    PCR-denaturing gradient gel electrophoresis (PCR-DGGE) was used to study the diversity of lactic acid bacteria (LAB) in two Flemish artisan raw milk Gouda-type cheeses. In parallel, conventional culturing was performed. Isolates were identified using (GTG)(5)-PCR and sequence analysis of 16S rRNA and pheS genes. Discriminant analysis revealed some differences in overall LAB diversity between the two batches and between the two cheeses. Within each batch, the diversity of 8- and 12-week-old cheeses was relatively similar. Conventional isolation mainly revealed the presence of Lactobacillus paracasei, Lactobacillus plantarum, Lactobacillus brevis, Lactobacillus rhamnosus and Pediococcus pentosaceus. PCR-DGGE revealed the presence of three species of which no isolates were recovered, i.e. Enterococcus faecalis, Lactobacillus parabuchneri and Lactobacillus gallinarum. Conversely, not all isolated bacteria were detected by PCR-DGGE. We recommend the integrated use of culture-dependent and -independent approaches to maximally encompass the taxonomic spectrum of LAB occurring in Gouda-type and other cheeses.

    Full Text Available The aim of this study is the isolation, characterization and identification of autochthonous lactic acid bacteria (LAB from artisanal Vlasina raw goat's milk cheese for the selection of potential starter cultures. Soft white Vlasina cheese was manufactured at a household on the Stara Planina Mountain using traditional techniques without starter cultures. One hundred and forty nine LAB isolates were collected from two samples of Vlasina cheese, designated as BGVL2 (5 days old and BGVL2a (15 days old. The population of LAB in the cheese samples was characterized by phenotype-based assays and presumptively identified using repetitive element palindromic polymerase chain reaction (rep-PCR with the primer (GTG5. Results were confirmed by 16S rDNA sequencing. Among the BGVL2 isolates (56, the most numerous LAB species were Leuconostoc pseudomesenteroides (27 and Lactococcus lactis (26. In 15-day-old BGVL2a (93 isolates, Lactobacillus plantarum (33, Enterococcus durans (26 and Pediococcus pentosaceus (14 were predominant. Lc. lactis ssp. lactis BGVL2-8 showed good acidification ability and the ability to produce antimicrobial compounds, Lb. plantarum BGVL2a-18 had good proteolytic ability and produced exopolysaccharides, while BGVL2-29 and BGVL2-63, which belonged to the species Ln. pseudomesenteroides, utilized citrate and produced diacetyl and acetoin. They appeared to be suitable candidates for inclusion in the starter culture. This study contributed to the understanding of the role of autochthonous LAB in the quality of artisanal cheese and the possibility of using the selected LAB as potential starter cultures for cheese making under controlled conditions.

    Full Text Available The aim of this study was to assess the microbial characteristics of a batch of Conciato Romano during manufacturing and ripening. Conciato Romano is a traditional cheese made from raw sheep’s milk without starter cultures in the province of Caserta (Southern Italy using traditional methods. A total of 7 samples (raw milk, curd and cheese wheels taken after 25, 60, 120 and 180 days of ripening were screened for hygiene indicators microorganisms counts (total viable count, Enterobacteriaceae, total coliforms, E. coli, clostridia sulphite reducing, yeasts, coagulasepositive staphylococci, enterococci, for autochthonous lactic acid flora counts (mesophilic and thermophilic lactococci and lattobacilli, and also for Salmonella spp. and Listeria monocytogenes presence. In raw milk, low values were detected for total aerobic flora (3.2 log cfu/mL, Enterobacteriaceae and total coliforms (2 cfu/mL, and the autochthonous starter lactic flora was predominant (3.2 log cfu/mL. During ripening, total aerobic flora was constant (107-108 cfu/g; total coliforms, E. coli, Enterobacteriaceae and yeasts were not detected starting from the 60th day of ripening. Enterococci ranged from 4.2 to 6.2 log cfu/g. The mesophilic lactic flora was dominant with values always >6 log cfu/g during the whole ripening period. Pathogens were never detected. The results of this study highlighted how the raw milk indigenous lactic flora, the traditional production techniques and the cheesemaker’s experience are essential to guarantee the unique nature of Conciato Romano.

    Full Text Available In this study, prevalence, biotechnological and safety profi les of 588 Enterococcus isolates isolated from raw milk and Istrian cheese during diff erent stages of ripening were analyzed. Despite the low and variable presence of enterococci in milk ((3.65±2.93 log CFU/mL, highly comparable enterococcal populations were established aft er 30 days of cheese ripening ((7.96±0.80 log CFU/g, confi rming Enterococcus spp. as a major part of the core microbiota of Istrian cheese. The dominant species were E. faecium (53.8 % and E. faecalis (42.4 %, while minor groups, consisting of E. durans (2.84 % and E. casselifl avus (0.95 %, also occurred. A pronounced intraspecies variability was noticed based on molecular fi ngerprinting, with 35 strains (genotypes detected. Most of the genotypes were farm-specifi c with one third being shared between the farms. This genotype variability refl ected particular diff erences of Istrian cheese production, mainly variable salt concentration, ripening temperature and air humidity as well as microclimatic or vegetation conditions. There was considerable variation between the strains of the same species regarding wide range of biotechnologically important traits as well as their ability to survive in simulated gastrointestinal conditions. A considerable number of strains were resistant to critically important antibiotics such as tetracycline (43.56 %, erythromycin (35.79 % and vancomycin (23.48 %. Polymerase chain reaction-based detection did not identify any of the common genetic determinants for vancomycin and erythromycin resistance; for tetracycline tetM gene was detected. The presence of virulence genes including agg, efaAfs, gelE, cylM, cylB, cylA, esp, efaAfm, cob and cpd was frequently recorded, especially among E. faecalis strains.

    The objective of this review is to present an overview of some of the most commonly consumed artisanal Mexican cheeses, as well as those cheeses that show potential for a protected designation of origin. A description is given for each of these cheeses, including information on their distinguishing characteristics that makes some of them potential candidates for achieving a protected designation of origin status. This distinction could help to expand their frontiers and allow them to become better known and appreciated in other parts of the world. Due to the scarcity of scientific studies concerning artisanal Mexican cheeses, which would ultimately aid in the standardization of manufacturing processes and in the establishment of regulations related to their production, more than 40 varieties of artisanal cheese are in danger of disappearing. To preserve these cheeses, it is necessary to address this challenge by working jointly with government, artisanal cheesemaking organizations, industry, academics, and commercial partners on the implementation of strategies to protect and preserve their artisanal means of production. With sufficient information, official Mexican regulations could be established that would encompass and regulate the manufacture of Mexican artisanal cheeses. Finally, as many Mexican artisanal cheeses are produced from raw milk, more scientific studies are required to show the role of the lactic acid bacteria and their antagonistic effect on pathogenic microorganisms during aging following cheese making.

    Full Text Available Traditional Serbian cheese production has a long history and generates products with rich flavor profiles. To enable the industrial manufacture of these home-made Serbian cheeses, the lactic acid bacteria present in them needs to be characterized. Five fresh white cheeses made from raw cow’s milk without commercial starter cultures were collected from households on the mountain Stara Planina, Serbia. According to phenotypical and molecular analysis, 262 isolated Lwere found to belong to Lactococcus, Lactobacillus, Streptococcus, Leuconostoc or Enterococcus. The unique bacterial composition of each cheese indicates that the preservation of household industry is the way to maintain production of distinct cheeses.

    2013-03-01

    Full Text Available This essay is about the ensuing problem that in general it is nothelpful to talk about non-standard knowledge practices as modeled after our Western ideas of what knowledge is. It negotiates this problem by arguing that artisanal knowledge is an independent and self-contained mode of knowledge and is arranged in three parts. In the first part an outline is given of the key assumptions of the interactionist conception of knowledge that needs to be put in place as an alternative to the basically Kantian mixture of empiricist and rationalist assumptions of the folk model of Western academic thinking about knowledge. In this interactionist conception of knowledgeartisanal knowledge gets center stage. In the second part, the notion of craftknowledge is opened up as much as possible. The third and final part takes upthe question whether craft knowledge is a cultural universal.

    Minas artisanal cheese, produced in the Campo das Vertentes region of Brazil, is made from raw milk and endogenous starter cultures. Although this cheese is of great historical and socioeconomic importance, little information is available about its microbiological and physical-chemical qualities, or about its beneficial microbiota. This work was aimed at evaluating the qualities of the cheese and the components used for its production, comparing samples collected during the dry and rainy seasons. We also conducted molecular identification and isolated 50 samples of lactic acid bacteria from cheese (n=21), water (n=3), raw milk (n=9), and endogenous starter culture (n=17). The microbiological quality of the cheese, water, raw milk, and endogenous starter culture was lower during the rainy period, given the higher counts of coagulase-positive Staphylococcus and total and thermotolerant coliforms. Enterococcus faecalis was the lactic acid bacteria isolated most frequently (42.86%) in cheese samples, followed by Lactococcus lactis (28.57%) and Lactobacillus plantarum (14.29%). Lactobacillus brevis (5.88%), Enterococcus pseudoavium (5.88%), Enterococcus durans (5.88%), and Aerococcus viridans (5.88%) were isolated from endogenous starter cultures and are described for the first time in the literature. The lactic acid bacteria identified in the analyzed cheeses may inhibit undesirable microbiota and contribute to the safety and flavor of the cheese, but this needs to be evaluated in future research.

    2013-12-01

    Full Text Available Uruguayan artisan cheese is elaborated with raw milk and non-commercial starters. The associated native microbiota may include lactic acid bacteria and also potentially pathogenic bacteria. Lactic acid bacteria were isolated from artisan cheese, raw milk, and non-commercial starter cultures, and their potential bacteriocin production was assessed. A culture collection of 509 isolates was obtained, and five isolates were bacteriocin-producers and were identified as Enterococcus durans,Lactobacillus casei, and Lactococcus lactis. No evidence of potential virulence factors were found in E. durans strains. These are promising results in terms of using these native strains for cheese manufacture and to obtain safe products.

    Full Text Available The decline in apprenticeship in both the public and private sectors, the increasing use of sub-contractors as well as the uncoordinated approach in the informal sector are contributing factors to the shortage of skilled artisans in the construction industry. Artisans training can be introduced and implemented through the adoption of progressive implementation of construction processes commencing work from areas requiring low skill demands to areas of high skill demand. The success of this principle hinges on the collaborative effort of the key project stakeholders. The client should be willing to absorb extra cost and delays in the project; the design and contract documentation should facilitate on-site training, and  the consultant actively guide the contractor and the construction processes to achieve the training objectives. The exploratory research method was adopted in this study and research revealed that this principle was used in a project in the UK and in the development of infrastructure in the tourism industry of South Africa .It is being recommended that the principle be adapted by the public sector for the development of small size infrastructures that can be repeated in many places. This will boost the quality and quantity of artisans, enhance employability, reduce rural urban migration and alleviate poverty.Keywords: Skilled artisans, on-site training, progressive construction processes, project stakeholders, contract documentation.

    Testicular cancer is thought to have a great impact on its survivors, yet there has been limited literature on the topic globally and no literature on the topic in Lebanon and the Arab region. The purpose of this study was to explore the lived experience of Lebanese testicular cancer survivors and gain an in-depth understanding of the psychosexual aspect of their experience. A hermeneutic phenomenological approach with semistructured digitally recorded interviews and observational field notes was utilized. A purposive sample of Lebanese testicular cancer survivors, aged between 18 and 50 years, in remission for at least 3 years, and willing to share personal information was recruited. Interviews were transcribed verbatim in Arabic. Data saturation was achieved at the seventh interview; a total of eight informants were recruited. The opening question was, "Tell me about your life since you got treated for testicular cancer," and was followed by probing questions. Two to three weeks after the initial interview, informants were called to validate the investigators' primary analysis. Six core themes emerged: cancer perception in the Lebanese culture; "do not show, do not tell"; cancer experience is a turning point; fertility, manhood, and relationships; coping with cancer; and preserved aspects of life. The findings provide an in-depth understanding of the experience of Lebanese testicular cancer survivors with a focus on the psychosexual aspect of this experience. The results suggest the need to educate patients about testicular cancer and its effect on their fertility.

    Full Text Available Orientation: South Africa is facing a critical shortage of artisans. Therefore it is important to investigate which factors contribute to the retention of artisans by organisations.Research purpose: The objective of this study was to investigate the factors that are important for artisan retention at a South African organisation.Motivation for the study: Organisations that employ artisans need to understand what the main reasons are for keeping or losing artisans from the perspective of the artisans themselves. This information can be used to plan and implement interventions to deal with artisan retention in organisations.Research design, approach and method: A qualitative design was used and a purposive sample was taken (n = 14. A biographical questionnaire was administered and semi-structured interviews were conducted to gather data from artisans.Main findings: Remuneration had the highest rank of all the factors for the retention of artisans, closely followed by development opportunities. Other factors that were perceived as important for artisan retention included equality, recognition, management and the working environment, and working relationships.Practical implications: Organisations that employ artisans should especially attend to their remuneration and development opportunities.Contribution: The results of this study add to the knowledge of why artisans remain with a specific organisation.

    Full Text Available This study investigated the presence of Arcobacter species in two cheese factories; a total of 22 environmental samples and 10 food samples were collected from an artisanal and an industrial cheese factory; Arcobacter species were isolated after enrichment, and isolates were identified at species level by multiplex-polymerase chain reaction (PCR assay. In the artisanal cheese factory, Arcobacter spp. were isolated from several environmental samples, cow and water buffalo raw milk and ricotta cheese. In the industrial plant, Arcobacter spp. were isolated from surfaces not in contact with food and from a cleaned surface in contact with food; no Arcobacter spp. was isolated from food. All isolates were identified as A. butzleri. We report of the presence of A. butzleri in a ready-to-eat cheese produced for retail. In addition, the isolation of A. butzleri in food processing surfaces in the two cheese factories could be assessed as a source of potential contamination for cheeses

    Our modus operandi is to adopt an ontological and epistemological approach in the study of Orientalism, while, at the same time, exploring the realities of sectarian divisions in Lebanon, which determine how people, in the formation of identity, respond to and interact with their immediate surroundings. Bearing in mind the inherent religious differences that divide the Lebanese, where then is otherness to be located? Arguably, the ideological fissures that exist between them have allowed outsiders to penetrate their culture and to monopolise their knowledge.

  4. Toxicogenetic profile and cancer risk in Lebanese.

    Dhaini, Hassan R; Kobeissi, Loulou

    2014-01-01

    An increasing number of genetic polymorphisms in drug-metabolizing enzymes (DME) were identified among different ethnic groups. Some of these polymorphisms are associated with an increased cancer risk, while others remain equivocal. However, there is sufficient evidence that these associations become significant in populations overexposed to environmental carcinogens. Hence, genetic differences in expression activity of both Phase I and Phase II enzymes may affect cancer risk in exposed populations. In Lebanon, there has been a marked rise in reported cancer incidence since the 1990s. There are also indicators of exposure to unusually high levels of environmental pollutants and carcinogens in the country. This review considers this high cancer incidence by exploring a potential gene-environment model based on available DME polymorphism prevalence, and their impact on bladder, colorectal, prostate, breast, and lung cancer in the Lebanese population. The examined DME include glutathione S-transferases (GST), N-acetyltransferases (NAT), and cytochromes P-450 (CYP). Data suggest that these DME influence bladder cancer risk in the Lebanese population. Evidence indicates that identification of a gene-environment interaction model may help in defining future research priorities and preventive cancer control strategies in this country, particularly for breast and lung cancer.

  5. Phytomining for Artisanal Gold Mine Tailings Management

    2016-08-01

    Full Text Available Mine tailings are generally disposed of by artisanal and small scale gold miners in poorly constructed containment areas and this leads to environmental risk. Gold phytomining could be a possible option for tailings management at artisanal and small-scale gold mining (ASGM locations where plants accumulate residual gold in their above ground biomass. The value of metal recovered from plants could offset some of the costs of environmental management. Getting gold into plants has been repeatedly demonstrated by many research groups; however, a simple working technology to get gold out of plants is less well described. A field experiment to assess the relevance of the technology to artisanal miners was conducted in Central Lombok, Indonesia between April and June 2015. Tobacco was planted in cyanidation tailings (1 mg/kg gold and grown for 2.5 months before the entire plot area was irrigated with NaCN to induce metal uptake. Biomass was then harvested (100 kg, air dried, and ashed by miners in equipment currently used to ash activated carbon at the end of a cyanide leach circuit. Borax and silver as a collector metal were added to the tobacco ash and smelted at high temperature to extract metals from the ash. The mass of the final bullion (39 g was greater than the mass of silver used as a collector (31 g, indicating recovery of metals from the biomass through the smelt process. The gold yield of this trial was low (1.2 mg/kg dry weight biomass concentration, indicating that considerable work must still be done to optimise valuable metal recovery by plants at the field scale. However, the described method to process the biomass was technically feasible, and represents a valid technique that artisanal and small-scale gold miners are willing to adopt if the economic case is good.

    The study evaluated the antimicrobial resistance of molecularly characterized strains of Staphylococcus aureus and S. saprophyticus isolated from 3 Lebanese dairy-based food products that are sometimes consumed raw: kishk, shanklish and baladi cheese. Suspected Staphylococcus isolates were identified initially using standard biochemical tests, then strains that were confirmed by polymerase chain reaction (29 S. aureus and 17 S. saprophyticus) were evaluated for their susceptibility to different antimicrobials. The highest levels of contamination with staphylococci were in baladi cheese. Resistance rates ranged from 67% to gentamicin to 94% to oxacillin and clindamycin. The results suggest that these locally made dairy-based foods may act as vehicles for the transmission of antimicrobial-resistant Staphylococcus spp.

    Autism spectrum disorder (ASD) is characterized by ritualistic-repetitive behaviors and impaired verbal/non-verbal communication. Many ASD susceptibility genes implicated in neuronal pathways/brain development have been identified. The Lebanese population is ideal for uncovering recessive genes because of shared ancestry and a high rate of consanguineous marriages. Aims here are to analyze for published ASD genes and uncover novel inherited ASD susceptibility genes specific to the Lebanese. We recruited 36 ASD families (ASD: 37, unaffected parents: 36, unaffected siblings: 33) and 100 unaffected Lebanese controls. Cytogenetics 2.7 M Microarrays/CytoScan™ HD arrays allowed mapping of homozygous regions of the genome. The CNTNAP2 gene was screened by Sanger sequencing. Homozygosity mapping uncovered DPP4, TRHR, and MLF1 as novel candidate susceptibility genes for ASD in the Lebanese. Sequencing of hot spot exons in CNTNAP2 led to discovery of a 5 bp insertion in 23/37 ASD patients. This mutation was present in unaffected family members and unaffected Lebanese controls. Although a slight increase in number was observed in ASD patients and family members compared to controls, there were no significant differences in allele frequencies between affecteds and controls (C/TTCTG: γ2 value = 0.014; p = 0.904). The CNTNAP2 polymorphism identified in this population, hence, is not linked to the ASD phenotype. PMID:28358038

  8. Behaviour of Salmonella Typhimurium during production and storage of artisan water buffalo mozzarella cheese

    2012-07-01

    Full Text Available Water buffalo mozzarella cheese (WBMC is a fresh pasta filata cheese produced from whole chilled buffalo milk. Although pasteurization of milk and the use of defined starter cultures are recommended, traditional technology involving the use of unpasteurized milk and natural whey cultures is still employed for WBMC production in Italy. The aim of this study were to assess the behaviour of Salmonella Typhimurium during the production of artisan water buffalo mozzarella cheese and during its shelf life under different temperature conditions. Raw milk was inoculated with S. Typhimurium and the evolution of S. Typhimurium count during production and shelf life was monitored. In artisan WBMC production technology S. Typhimurium multiplied in the curd during ripening, but its growth rate expressed in log CFU/g/h was lower than the growth rate reported by theoretical predictions. Stretching proved to be a process with good repeatability and able to reduce S. Typhimurium contamination by 5.5 Log CFU/g. The intrinsic characteristics of traditional WBMC proved to be unable to obstacolate the growth of S. Typhimurium during storage in the case of thermal abuse. Control of raw milk contamination and a proper refrigeration temperature are key factors in reducing the risk for consumers.

    2007-01-01

    The objectives of this study were to establish weight, height and body mass index curves and to calculate the prevalence of obesity by sex and age groups in Lebanese adolescents of private schools. Body weight, height and body mass index (BMI) were measured among 12299 adolescents aged 10 to 18 years from Lebanese private schools. Adolescents' growth charts were established. Obesity and at risk of obesity individuals were identified according to International Obesity Taskforce thresholds, and our numbers were compared to those of other countries. Curves of weight, height and BMI were drawn. In boys, 10.1% were obese and 28.8% at risk of obesity. In girls, 4.2% were obese and 19.0% were at risk of obesity. Lebanese private schools adolescents, particularly boys, present high prevalences of obesity and risk of obesity. Pediatricians should identify early adolescents at greater risk, in order to achieve a more favorable prognosis.

    The objective of this paper is to assess the impact of the new ISO 9001:2000 standard on the Quality Management Systems (QMS) of Lebanese firms that were already certified under ISO 9000:1994. To get an accurate feedback of stakeholders in a firm, three different questionnaires were developed and distributed to management, employees, and customers respectively. Empirical results indicate that ISO 9001:2000 has improved the QMS performance of Lebanese firms over that of the 1994 edition. Nevertheless, results showed that the new standard still has some weaknesses when it comes to improving suppliers' relationships and empowering employees.

    Given limited funds for research and widespread degradation of ecosystems, environmental scientists should geographically target their studies where they will be most effective. However, in academic areas such as conservation and natural resource management there is often a mismatch between the geographic foci of research effort/funding and research needs. The former frequently being focused in the developed world while the latter is greater in the biodiverse countries of the Global South. Here, we adopt a bibliometric approach to test this hypothesis using research on artisanal fisheries. Such fisheries occur throughout the world, but are especially prominent in developing countries where they are important for supporting local livelihoods, food security and poverty alleviation. Moreover, most artisanal fisheries in the Global South are unregulated and unmonitored and are in urgent need of science-based management to ensure future sustainability. Our results indicate that, as predicted, global research networks and centres of knowledge production are predominantly located in developed countries, indicating a global mismatch between research needs and capacity.

    Artisanal miners employ rudimentary techniques for minéral extraction and often operate under hazardous, labour intensive, highly disorganized and illegal conditions. Gold is the main mineral extracted by artisanal miners, and the ecological and human health impacts resulting from mercury (Hg) use in gold extraction warrant special consideration. More than 30% of world's 13 million artisanal miners are women and, as they are often perceived to be less suited for labour intensive mining methods, the majority of women work in the processing aspect of artisanal mining, including amalgamation with Hg. As women are also predominantly responsible for food preparation, they are in an excellent position to respond to health risks associated with consumption of Hg-contaminated foods in impacted areas. In addition to their influence on consumption habits, women in artisanal mining communities may be in a position to effect positive change with respect to the technologies employed. Thus, gender sensitive approaches are necessary to reduce exposure risks to women and their families, promote clean technologies and support the development of stronger, healthier artisanal mining communities. This paper describes the roles of women in artisanal gold mining, highlights their importance in reducing the Hg exposure in these communities, and provides insight into how risks from Hg pollution can effectively be communicated and mitigated.

    Nasr, Rawad; Tall, Ibrahim; Nachabe, Nour; Chaaban, Farid

    2016-07-01

    The main purpose of this paper is to estimate the carbon footprint of a typical Lebanese household, and compare the results with international standards and trends. The estimation of this footprint will reflect the impact of the daily Lebanese household activities on the environment in terms of carbon dioxide emissions. The method used in estimating the carbon emissions is based on gathering the primary footprints from various household activities. Another proposed method that provides more accurate results is the estimation of emissions based on secondary footprint, which reflects the total emissions not only from the regular activities but also from a lifecycle perspective. Practical and feasible solutions were proposed to help reduce the amount of C02 emissions per household. This would lead to a better air quality, money savings, greenhouse gases emissions reduction and would ensure the sustainability and prosperity of future generations. A detailed survey was conducted in which the questions were focused mainly on energy, food, and transportation issues. The fourteen questions were addressed to one hundred families in different Lebanese regions coming from different social and economic backgrounds. This diversity would constitute a reflective sample of the actual Lebanese society, allowing us to extrapolate the gathered results on a national level.

    2017-01-01

    Australia’s regulatory framework has resulted in the standardisation of cheese production based on pasteurisation. Up until early 2015, regulations effectively prohibited raw milk cheese-making in Australia and thus stifled artisanal on-farm production. Although the introduction of Food Standards Australia New Zealand Standard 4.2.4 has allowed the production of certain hard, low-moisture raw milk cheeses, the new standard is rigid and does not encourage new entrants into the emerging raw ...

  2. Work and Masculinity in Katanga’s Artisanal Mines

    Directory of Open Access Journals (Sweden)

    Jeroen Cuvelier

    2014-01-01

    Full Text Available This article, based on 16 months of anthropological fieldwork between 2005 and 2012, examines the relationship between work and masculinity among artisanal miners, or creuseurs, in Katanga, the southeastern province of the Democratic Republic of the Congo. It argues that men’s involvement in artisanal mining should be considered not only as an economic survival strategy but also as an attempt to experiment with new ways of being a man in a context of economic crisis and changing gender relations. Furthermore, the article criticizes the tendency to downplay or underestimate the complexity and diversity of processes of masculine identity construction in Africa’s artisanal-mining areas. In order to do justice to the intricacy of these processes, the article proposes using concepts and insights from the field of masculinity studies and distinguishing between a levelling and a differentiating trend in artisanal miners’ masculinity practices.

    Full Text Available Most historians interpret the political situation of the artisans in the XIX century in Colombia like that of a social group which was compelled to take part in politics, because the pressure of the economic policies of free trade tendency. This thesis has been sustained on the basis of the artisan societies that were created since 1838 on, against the policies of the government. In spite of this common thesis, I dare say that even though the artisans protested by brandishing arguments against the free trade, nevertheless their political activity took place without knowing the real implications of the free trade concerning their own production. I will demonstrate this thesis of mine by focusing my study on the situation of the artisans in Bogotá, particularly the period between 1832 and 1836; in this period the "rst riot against the free trade took place in the XIX century in Bogotá. My arguments shall sustain that the custom laws reforms were protectionist essentially, and despite that the artisans protested against the free trade. I will also put under evidence that the artisan¿s products for the home market did not compete with the foreign products.

    The present study aimed to investigate the presence, distribution, and persistence of Arcobacter spp. in an artisanal dairy plant and to test the isolates to determine their different genotypes in the processing plant and in foods. Samples were collected in an artisanal cheese factory on four occasions between October and December 2012. Food samples (raw milk, ricotta cheese, mozzarella cheese, and conditioning liquid), water samples, and environmental samples were analyzed by the culture method; isolates were identified by multiplex PCR and genotyped by pulsed-field gel electrophoresis (PFGE) analysis. Arcobacter butzleri was isolated from 29 out of 59 samples (46.6%), 22 of which were from environmental samples and 7 of which were from food samples. Cluster analysis divided the strains into 47 PFGE patterns: 14 PFGE clusters and 33 unique types. Our findings indicate that the plant harbored numerous A. butzleri pulsotypes and that the manual cleaning and sanitation in the studied dairy plant do not effectively remove Arcobacter. The recurrent isolation of A. butzleri suggests that the environmental conditions in the dairy plant constitute a good ecological niche for the colonization of this microorganism. In some cases, the presence of indistinguishable strains isolated from the same facilities on different sampling days showed that these strains were persistent in the processing environment.

    Breast cancer is commonest cancer in women worldwide. Elucidation of underlying biology and molecular pathways is necessary for improving therapeutic options and clinical outcomes. Molecular alterations in breast cancer are complex and involve cross-talk between multiple signaling pathways. The aim of this study is to extract a unique mRNA fingerprint of breast cancer in Lebanese women using microarray technologies. Gene-expression profiles of 94 fresh breast tissue samples (84 cancerous/10 non-tumor adjacent samples) were analyzed using GeneChip Human Genome U133 Plus 2.0 arrays. Quantitative real-time PCR was employed to validate candidate genes. Differentially expressed genes between breast cancer and non-tumor tissues were screened. Significant differences in gene expression were established for COL11A1/COL10A1/MMP1/COL6A6/DLK1/S100P/CXCL11/SOX11/LEP/ADIPOQ/OXTR/FOSL1/ACSBG1 and C21orf37. Pathways/diseases representing these genes were retrieved and linked using PANTHER®/Pathway Studio®. Many of the deregulated genes are associated with extracellular matrix, inflammation, angiogenesis, metastasis, differentiation, cell proliferation and tumorigenesis. Characteristics of breast cancers in Lebanese were compared to those of women from Western populations to explain why breast cancer is more aggressive and presents a decade earlier in Lebanese victims. Delineating molecular mechanisms of breast cancer in Lebanese women led to key genes which could serve as potential biomarkers and/or novel drug targets for breast cancer. PMID:27857161

    2017-05-01

    Full Text Available The serrano artisan cheese produced from raw milk of dairy cattle is a typical product of high-altitude farms in the states of Santa Catarina and Rio Grande do Sul. However, marketing of the cheeses occurs illegally because they lack the minimum maturation period required for cheese produced from raw milk. The production of artisan cheeses is required to follow strict hygiene standards. This study aimed to test the quality and safety of cheeses that were produced in 31 farms of the Serrana region in Santa Catarina after 14 and 28 days of maturation. Coliform count was measured at 35 °C, and presence of other microorganisms such as Escherichia coli, Staphylococcus, Listeria spp., and Salmonella spp. were also tested. Fat and protein percentages, acidity, salt content, and humidity were also evaluated. Data were subjected to statistical analyses using the SAS® software. After 14 and 28 days of maturation, 74.19% (23/31 and 64.52% (20/31 of samples, respectively, showed higher numbers of coliforms at 35 °C than those permissible by law. Higher than permissible numbers of E. coli were observed in 45.16% (14/31 and 48.39% (15/31 of the samples analyzed after 14 and 28 days of maturation, respectively. Coagulase-positive staphylococci values above 103 CFU/g were observed in 54.84% (17/31 and 51.61% (16/31 of cheese samples after 14 and 28 days of maturation, respectively. Contamination with Salmonella spp. was not detected. However, Listeria monocytogenes serovar 4b was isolated in 3.23% (1/31 and 6.45% (2/31 of samples after 14 and 28 days of maturation, respectively. The results of humidity tests classified the cheese samples into three categories: low, medium, and high humidity. Semi fat cheeses were predominant in both maturation periods, although the samples were classified in thin, semi fat, and fat cheeses. The main variations in the compositions of analyzed samples occurred for salt and acidity levels. The maturation process has not proven

    There is a lack of knowledge regarding the composition, production, distribution, and consumption of artisanal alcohol, particularly in the developing world. In Nahuala, an indigenous Mayan municipality located in highland Guatemala, heavy alcohol consumption appears to have had a significant negative impact on health, a major role in cases of violence and domestic abuse, and a link to street habitation. Cuxa, an artisanally, as well as commercially produced sugarcane alcohol, is widely consumed by heavy drinkers in this community. Cuxa samples from all distribution points in the community were obtained and chemically analyzed for health-relevant constituents and contaminants including methanol, acetaldehyde, higher alcohols, and metals. From those, only acetaldehyde was confirmed to be present in unusually high levels (up to 126 g/hl of pure alcohol), particularly in samples that were produced clandestinely. Acetaldehyde has been evaluated as 'possibly carcinogenic' and has also been identified as having significant human exposure in a recent risk assessment. This study explores the reasons for the elevated levels of acetaldehyde, through both sampling and analyses of raw and intermediary products of cuxa production, as well as interviews from producers of the clandestine alcohol. For further insight, we experimentally produced this alcohol in our laboratory, based on the directions provided by the producers, as well as materials from the town itself. Based on these data, the origin of the acetaldehyde contamination appears to be due to chemical changes induced during processing, with the major causative factors consisting of poor hygiene, aerobic working conditions, and inadequate yeast strains, compounded by flawed distillation methodology that neglects separation of the first fractions of the distillate. These results indicate a preventable public health concern for consumers, which can be overcome through education about good manufacturing practices

    Full Text Available The typical Lebanese classroom is teacher centered, whereby the teacher is respected and is considered to be the bearer of all information. Active learning teaching methods are not in the Lebanese teacher’s expectations. The students are not expected to assume responsibility for their educational development and learning process. This paper aims to highlight the issues that prevent teachers from adopting the active learning teaching method. A small scale survey from 100 teachers of 10 different schools selected from various areas in Lebanon was undertaken. The survey results were compared and tested in order to evaluate the reasons for not adopting active learning instruction in the Lebanese schools.

    Full Text Available Lebanon is a small democratic country with a population of less than four million and a range of diversity; there are at least 18 different religious sects and 19 different political parties. The diversity among ethnic, religious and/or political groups has created conflicts that severely impact the Lebanese economy, environment, politics and most importance our young citizens. The aim of this investigation is to capture students’ awareness and attitudes toward the accountability and mechanisms of peace and democracy. Data for the study was obtained from extensive literature reviews and questionnaire surveys of 70 high school students. The investigation was conducted in the fall of the year 2013. The results of the study showed that most Lebanese young citizen view peace and democracy process associated with the end of violence and conflict behaviors; very small percent of respondents believe that bringing peace and democracy process should be answered by the people or by themselves. Results also indicate a lack of a sense of security among young citizen. This raises the urgent need to put into practice an effective peace education program that inspires and motivates young citizens to be involved in the peace and the democracy building process.

    2014-04-01

    Full Text Available There is an expressive artisanal cheeses production in Brazil, manufactured from raw milk, and within this context, the state of Minas Gerais has a highlight in this activity with its five micro regions officially recognized. Within these, “Campo das Vertentes” was the last to have recognition. Evaluating the effect of dry and wet periods during the ripening of artisanal Minas cheese of the micro region above mentioned was the main objective of this study, which also related aspects of physicochemical composition of 10 to 30 days of ripening. Four registered dairies were selected and who attended legal requirements and good manufacturing practice to compose the experiment. The analysis of moisture content, moisture to the non fat substance (MNFS and pH showed that these values varied greatly among cheeses and were highest in the dry season. Indexes of proteolysis behaved with variation between samples and advanced in the period of ripening, however, they were higher in the wet season. Even aware that the moisture content of the cheeses exerts strong influence on proteolysis, as well as other factors such as dosage of coagulant and “drop”, the room temperature observed in two periods of ripening was also very important for the advancement of proteolysis.

    2002-12-01

    Elemental Hg-Au amalgamation mining practices are used widely in many developing countries resulting in significant Hg contamination of surrounding ecosystems. We have measured total Hg and methyl-Hg concentrations in sediment and water collected from artisanal Au mines and these are the first Hg speciation data from such mines in Suriname. Total Hg and methyl-Hg contents in mine-waste sediment and water are elevated over local uncontaminated baselines. Total Hg (10-930 ng/L) and methyl-Hg (0.02-3.8 ng/L) are highly elevated in mine waters. Increasing total Hg contents in discharged mine waters correlate with increasing water turbidity indicating that most Hg transport is on suspended particulates. Our Hg results are similar to those found in artisanal Au mines in the Amazon basin, where Hg contamination has led to adverse effects on tropical ecosystems.

  6. Artisanal Fisheries in Zimbabwe: Options for Effective Management

    Directory of Open Access Journals (Sweden)

    Wilson Mhlanga

    2013-08-01

    Full Text Available The small-scale (artisanal fisheries in Zimbabwe play an important role in income-generation and food security at the household level. This sector has the potential to significantly increase its contribution to household income and food security if more effective fisheries management strategies are put in place. Historically, fisheries management has adopted a centralised “Top-down” approach. This approach has had very limited effectiveness. Over the last decade, efforts have been made to implement co-management in the fisheries sector. Several factors have hampered the success of fisheries co-management in the artisanal fishery. These factors have been institutional, ecological, human and financial. This paper discusses these factors and proposes possible solutions. A more innovative and effective fisheries management approach is also proposed.

    Leichtman, Mara A.

    2013-01-01

    This article examines the changing relationship between religion, secularism, national politics, and identity formation among Lebanese Christians in Senegal. Notre Dame du Liban, the first Lebanese religious institution in West Africa, draws on its Lebanese “national” character to accommodate Lebanese Maronite Catholic and Greek Orthodox Christians in Dakar, remaining an icon of “Lebanese” religion, yet departing from religious sectarianism in Lebanon. As such, transnational religion can vary from national religion, gaining new resonances and reinforcing a wider “secular” ethno-national identity. PMID:24077518

    Full Text Available Background. Ellis-van Creveld (EvC syndrome is a rare, autosomal recessive disorder characterized by short stature, short limbs, growth retardation, polydactyly, and ectodermal defects with cardiac anomalies occurring in around 60% of cases. EVC syndrome has been linked to mutations in EVC and EVC2 genes. Case Presentation. We report EvC syndrome in two unrelated Lebanese families both having homozygous mutations in the EVC2 gene, c.2653C>T (p.(Arg885* and c.2012_2015del (p.(Leu671* in exons 15 and 13, respectively, with the latter being reported for the first time. Conclusion. Although EvC has been largely described in the medical literature, clinical features of this syndrome vary. While more research is required to explore other genes involved in EvC, early diagnosis and therapeutic care are important to achieve a better quality of life.

    Many cultural and religious beliefs place virginity at a high level of social significance, in that women who lose their virginity before marriage may face humiliation, ostracism, divorce, and extreme violence. This led to an increase in the demand for virginity restoration through surgical hymen reconstruction among these cultures. However, data regarding the acceptance of hymenoplasty in societies that consider sexuality a taboo are scarce. In this cross-sectional study, we investigated the effects of gender and religion on sexual attitudes towards hymenoplasty, premarital sex, and virginity in a sample of 600 Lebanese university students. Our findings showed that approval of hymenoplasty was low among participants regardless of gender (25.7 % men vs. 19.1 % women) and religious affiliations (22.5 % Muslims vs. 22.3 % Christians). Arguments for rejection were rooted in moral ethics and personal convictions: "form of deceiving and cheating" (80.7 %) and "betrayal of honesty in the relationship" (80.4 %). Reasons for acceptance included: personal belief in "women's rights, autonomy, and freedom" (72.2 %) and "physical harm and death" (63.5 %).Male participants were more likely to approve premarital coital sex than females (61.0 vs. 27.3 %). Muslims were also more likely to reject marrying a non-virgin than Christians (39.9 vs. 18.0 %). Female participants expressed more tolerance towards marrying a non-virgin male partner (78.3 vs. 57.3 %). Low acceptance of hymenoplasty among Lebanese university students was found to be related to moral ethics and personal convictions independently from gender and religious affiliation. Differences in sexual attitudes towards premarital coital sex and virginity, however, were more significantly influenced by culture and religion.

    cheeses, the new standard is rigid and does not encourage new entrants into the emerging raw milk cheese consumer market. This article compares the Australian system with the French raw milk cheese regulation and production system, and argues that its approach in encouraging and supporting small farmhouse artisanal traditional raw milk cheese is beneficial to both producer and consumer, and has not resulted in any significant health risks. The Australian approach amounts to a missed opportunity to encourage the emergence of a value-added industry with local and export potential, and is at odds with important movements in food policy, such as recognition of the value of localism and terroir.

    The artisanal Minas cheese is produced from raw cow's milk and wooden utensils were employed in its manufacture, which were replaced by other materials at the request of local laws. This substitution caused changes in the traditional characteristics of cheese. Due to the absence of scientific studies indicating the microbial composition of biofilms formed on wooden forms, tables and shelves used in these cheese production, the present work evaluated the counts of Staphylococcus aureus, Escherichia coli, coliforms at 32 °C, yeasts, presumptive mesophilic Lactobacillus spp. and Lactococcus spp. in these biofilms, milk, whey endogenous culture and ripened cheese in two traditional regions: Serro and Serra da Canastra. Also, we checked for the presence of Salmonella sp. and Listeria monocytogenes in the ripened cheeses. The ultra structure of the biofilms was also assessed. Counts above legislation (> 2 log cfu/mL) for the pathogens evaluated were found in milk samples from both regions. Only one shelf and one form from Serro were above limits proposed (5 cfu/cm(2) for S. aureus and E. coli and 25 cfu/cm(2) for coliforms) in this study for contaminants evaluated. In Canastra, few utensils presented safe counting of pathogens. There was no Salmonella sp. and Listeria monocytogenes in the cheeses after ripening. Thus, the quality of the cheese is related to improving the microbiological quality of milk, implementation and maintenance of good manufacturing practices, correct cleaning of wooden utensils, and not its replacement.

    Full Text Available Changes in the microbial flora of “Caprino dei Nebrodi”, a raw goat’s milk cheese produced in Sicily, were studied during ripening. From 2 batches of cheese, 4 samples were taken at day 0, 2, 15, and 30 of ripening. Also, samples of curd and milk used in the manufacturing process were analyzed. By the end of the ripening process (day 30, high log10 cfu/g were found for Lactobacilli (7.20, Lattococci (7.10, and Enterococci (7.00, whereas counts of Enterobacteriaceae (3.91, Escherichia coli (3.30, and Staphylococcus (3.89 were found to be lower. The study provides useful information on the microbiological properties of “Caprino dei Nebrodi” cheese, and the results obtained suggest that in order to increase the quality of this artisanal product, it is necessary to improve the sanitary conditions of milking and cheese-making. The study was intended as a preliminary step towards the isolation and identification of bacterial species found in this type of goat’s cheese.

    A total of 114 lactic acid bacteria were isolated at one and 21 days of ripening from a traditional raw cow's milk cheese without the addition of starter culture, produced by three artisanal cheese-makers in Azores Island (Pico, Portugal). Identification to species and strain level was accomplished by16S rRNA gene and PFGE analysis. Carbohydrate utilization profiles were obtained with the relevant API kits. Isolates were evaluated according to safety and technological criteria. The most frequently observed genus identified by 16S rRNA sequencing analysis was Enterococcus, whereas API system mostly identified Lactobacillus. The highest percentages of antibiotic resistance were to nalidixic acid (95%), and aminoglycosides (64-87%). All isolates were sensitive to several beta-lactam antibiotics and negative for histamine and DNase production. Gelatinase activity was detected in 49.1% of isolates, 43% were able to degrade casein and 93% were α-hemolytic. Most enterococci presented virulence genes, such as gelE, asaI, ace. Diacetyl production was found to be species dependent and one strain (Leu. citreum) produced exopolysaccharides. Selected strains were further studied for technological application and were found to be slow acid producers in milk and experimental cheeses, a desirable trait for adjunct cultures. Two strains were selected on the basis of technological and safety application as adjunct cultures in cheese production and presented the best cheese aroma and flavor in consumer preference tests. This is the first effort to characterize Pico cheese LAB isolates for potential application as adjunct cultures; the results suggest the potential of two strains to improve the quality of this traditional raw milk product.

  20. Temporal Stability in Fishing Spots: Conservation and Co-Management in Brazilian Artisanal Coastal Fisheries

    2006-06-01

    Full Text Available The management of small-scale artisanal fisheries in Brazil should be a priority because of their importance as a source of food for internal markets and their location in sites with high biodiversity, such as the Atlantic Forest coast. Fishing spots, territories, and sea tenure have been widely studied within artisanal fisheries, and, in this study, a fishing spot of this type may be a defended area or an area that imposes rules for users, making the exclusion of outsiders feasible, or even a place in which fishing occurs with some exclusivity. This analysis takes into account the importance of fishing areas for the conservation of artisanal fishing in Brazil and the relative temporal stability of these areas. In particular, examples of the use of the marine space on the coast of Brazil in areas such as Rio de Janeiro, São Paulo, and Bahia States are presented. Fishing spots used by artisanal fishers were marked using a Global Positioning System (GPS. An informal division of the marine space and high temporal stability, often in the range of 10–30 yr, in the use of the fishing spots were found. For some fishing areas, information published in the 1960s provided a relevant comparison for the current use of the fishing spots at sea. Such information is very helpful for the management of artisanal fishing in Brazil because tourism has increased in some areas, recreational fishers have been fishing in marine spots used by artisanal fishers, and industrial fishers are spread over a wide range of the marine space in these coastal waters. This stability in the use of marine space among artisanal fishers plus local rules support the case for local co-management of artisanal fisheries. Reserving areas for artisanal fishers and understanding the behavior of other users are essential aspects for the management and conservation of artisanal fishing in Brazil.

    The absence of Croatian- and Arabic-language measures to assess illness representations has contributed to lack of research among Croatian and Lebanese populations. Utilising the robust confirmatory factor analysis (CFA) approach, this study aimed to validate Croatian and Arabic versions of the Revised Illness Perception Questionnaire for Healthy People (IPQ-RH) in the breast and cervical cancer contexts, and compared these illness perceptions among Croatian and Lebanese women living in Australia. Forward and back-translated versions of the IPQ-RH were administered in Croatian to Croatian-born (n = 238), and Arabic to Lebanese-born (n = 240) women. The IPQ-RH illness perceptions were assessed for each cancer type, and the Negative Affect (NA) subscale of the Positive and Negative Affect Schedule (PANAS) assessed discriminant validity. The CFA method demonstrated acceptable models across the Croatian and Lebanese IPQ-RH measures. The internal reliabilities for the IPQ-RH subscales were adequate and the subscales had low correlations with the NA subscale of the PANAS, indicating that the IPQ-RH measures are largely distinguishable from negative affective dispositions. These findings demonstrate that the Croatian and Lebanese IPQ-RH breast and cervical cancer measures have a factor structure similar to the originally developed IPQ-RH scale and provide further support for the theoretically developed illness representations. © 2013 John Wiley & Sons Ltd.

    Full Text Available Abstract Background In the past year Lebanon has been experiencing a nutritional transition in food choices from the typical Mediterranean diet to the fast food pattern. As a consequence, the dietary habits of young adults have been affected; thus, overweight and obesity are increasingly being observed among the young. The purpose of this study is to assess the prevalence of overweight and obesity on a sample of students from the Lebanese American University (in Beirut and to examine their eating habits. Methods A cross-sectional survey of 220 students (43.6% male and 56.4% female, aged 20 ± 1.9 years, were chosen randomly from the Lebanese American University (LAU campus during the fall 2006 semester. Students were asked to fill out a self-reported questionnaire that included questions on their eating, drinking and smoking habits. Also, their weight, height, percentage body fat and body mass index were measured. Body mass index (BMI was used to assess students' weight status. Statistical analyses were performed using the Statistical Package for Social Sciences software (version 13.0 to determine overweight and obesity among students and to categorize eating habits. Results This study showed that the majority of the students (64.7% were of normal weight (49% male students compared to 76.8% female students. The prevalence of overweight and obesity was more common among male students compared to females (37.5% and 12.5% vs. 13.6% and 3.2%, respectively. In contrast, 6.4% female students were underweight as compared to 1% males. Eating habits of the students showed that the majority (61.4% reported taking meals regularly. Female students showed healthier eating habits compared to male students in terms of daily breakfast intake and meal frequency. 53.3% of female students reported eating breakfast daily or three to four times per week compared to 52.1% of male students.

A sample (N = 476 of Lebanese undergraduates took part in the study (215 men and 261 women. They answered Arabic versions of the Oxford Happiness Inventory (OHI, the Satisfaction with Life Scale (SWLS, the Love of Life Scale, as well as five self-generated rating scales. Men obtained a significantly higher mean score on happiness and mental health than did their female counterparts, whereas women obtained a significantly higher mean score on religiosity. All the Pearson correlations between the study scales were significant and positive but one (between the self-rating scales of physical health and religiosity among men. Principal components analysis yielded one salient component separately in men and women, and labeled “Happiness, health, and religiosity.” The predictors of happiness as assessed with the OHI were love of life and SWLS, and happiness self-rating scale. Based on the responses of the present sample, it was concluded that those who consider themselves as felt happiness, reported higher mental and physical health, and being more religious.

    Full Text Available Purpose. The upper airway space is significant in orthodontic diagnosis and treatment planning. The objectives of this study are to assess the dimensions of soft tissue elements of the upper pharyngeal space and evaluate potential correlations with modifying variables such as gender, skeletal class, and anthropometric parameters. Materials and Methods. Lateral cephalograms were obtained from 117 healthy young adult Lebanese subjects. Nineteen cephalometric linear/angular measurements of the nasopharynx, oropharynx, and hypopharynx were recorded. Anthropometric parameters including body mass index and neck circumference were measured. Results. Significant differences were demonstrated for 12 out of the 19 parameters considered between genders. Uvula and tongue dimensions and the distances between epiglottis-posterior pharyngeal wall and epiglottis-posterior nasal spine were significantly larger in males. The anteroposterior inclination of the uvula and the distances between the uvula and posterior pharyngeal wall were significantly greater in females. No significant differences were found between skeletal classes relative to most of the variables. Body mass index and neck circumference were positively correlated with the dimensions of tongue and uvula. Conclusions. Sexual dimorphism relative to some cephalometric variables and anthropometric parameters may account partly for larger oronasopharyngeal spaces in females. Anthropometric data need to be accounted for in population-related comparisons.

    Dieting is becoming a popular phenomenon among university students to achieve or maintain a healthy weight. The purpose of this study is to obtain a preliminary understanding of what dieting practices university students use in order to achieve their desirable body weight and to determine the magnitude of body dissatisfaction in relation to weight status among a sample of students (n=252) from the Lebanese American University in Beirut, Lebanon. Students filled out a self-reported questionnaire that included questions on their dieting and physical activity practices in addition to the body shape questionnaire (BSQ). Weight and height were measured to calculate body mass index. Percentage body fat was measured using Tanita scale body fat analyzer 300A. The outcome of this study showed that smoking and unhealthy dieting practices were not common among students (only 26% reported smoking, 8% reported taking laxatives and 4% taking diet pills). Half of the students reported practicing regular physical activity. Multivitamin intake was also not popular among students. BSQ scores indicate that the majority of students were not worried about their body image perception (64% reported not being worried, 19% were slightly worried, 12% were moderately worried and 5% were extremely worried). A gender difference was observed in the BSQ scores, as 89% of the "extremely worried" students were females. Collectively, results indicate that unhealthy dieting practices are uncommon among students. However, developing health promotion awareness' programs to promote good self image within the concept of a realistic healthy weight will be beneficial, especially among females.

    Phenylketonuria is an autosomal recessive inborn error of metabolism resulting from phenylalanine hydroxylase deficiency. Genetic basis of phenylalanine hydroxylase deficiency has been reported in various European and Asian countries with few reports available in Arab populations of the Mediterranean region. This is the first pilot study describing phenotype and genotype of 23 Lebanese patients with phenylketonuria. 48% of the patients presented mainly with neurological signs at a mean age of 2 years 9 months, as newborn screening is not yet a nationwide policy. 56.5% of the patients had classical phenylketonuria. Thirteen different mutations were identified: splice site 52%, frameshift 31%, and missense 17% with no nonsense mutations. IVS10-11G>A was found mainly in Christians at high relative frequency whereas Muslims carried the G352fs and R261Q mutations. A rare splice mutation IVS7+1G>T, not described before, was identified in the homozygous state in one family with moderate phenylketonuria phenotype. Genotype-phenotype correlation using Guldberg arbitrary value method showed high consistency between predicted and observed phenotypes. Calculated homozygosity rate was 0.07 indicating the genetic heterogeneity in our patients. Our findings underline the admixture of different ethnicities and religions in Lebanon that might help tracing back the PAH gene flux history across the Mediterranean region.

Uvula and tongue dimensions and the distances between epiglottis-posterior pharyngeal wall and epiglottis-posterior nasal spine were significantly larger in males. The anteroposterior inclination of the uvula and the distances between the uvula and posterior pharyngeal wall were significantly greater in females. No significant differences were found between skeletal classes relative to most of the variables. Body mass index and neck circumference were positively correlated with the dimensions of tongue and uvula. Conclusions. Sexual dimorphism relative to some cephalometric variables and anthropometric parameters may account partly for larger oronasopharyngeal spaces in females. Anthropometric data need to be accounted for in population-related comparisons. PMID:28133482

    Artisanal 'Coalho' cheese is a product typically popular in the Brazilian north-eastern region. Production of this cheese represents about 9.2% of the internal crude product of Pernambuco State. Several peptides are generated from hydrolysis of αS1 -, αS2 -, β-, and κ-caseins during manufacture of this cheese. The commercial importance of Brazilian artisanal 'Coalho' cheese justifies the examination of both the protein and peptide profiles of cheeses from six cities of the semi-arid region of Pernambuco State, Brazil. SDS-PAGE of the aqueous extracts of 'Coalho' cheeses (WSP) showed bands of lactoferrin, β-lactoglobulin, β-lactoglobulin (dimer), α-lactoalbumin, bovine serum albumin, α-casein, β-casein, κ-casein and para-κ-casein. A total of 57 to 72 peptides were confirmed by mass spectra in the different samples of 'Coalho' cheese which 32 known peptides (11 from αS1 -casein, three from αS2 -casein, 15 from β-casein and three from κ-casein), comprising seven caseinphosphopeptides. Among the unidentified peptides, three showed high intensity peaks in all 'Coalho' cheeses studied (with molecular weights of 1597, 1725/1726, 2778/2779 Da). The proteomic studies revealed peptides that may represent molecular markers or fingerprints for investigating the quality control and regional characterisation of these 'Coalho' cheeses. © 2016 Society of Chemical Industry. © 2016 Society of Chemical Industry.

    2008-09-15

    In India, mining is one of the main economic activities since time immemorial, giving rise to a long historical tradition of artisanal mining. As modern mining rose during the colonial occupation, artisanal mining activities began to be overlooked and this great tradition became obscure. This invisibility, added with confusion with regard to legally accepted definitions has enhanced the negligence of the artisanal mining sector in India. This study draws attention to the contemporary artisanal mining practices in India - both traditional and non-traditional ones - with regard to four commodities, gold, tin, coal and lignite, and gemstones. It briefly discusses the occurrences of such mining, their salient features and concludes with four specific recommendations. Recommendations primarily deal with the need for creation of a broader information base, delineating a responsible body to deal with this kind of mining, legal reforms leading to definitional changes and finally, the recognition of the poverty alleviation potential of this sector in view of the Millennium Development Goals.

    Full Text Available Aim. Lebanon exhibits one of the highest prevalences of factor V-Leiden (FVL in the world (14.4%. The aim of this study is to evaluate the incidence of FVL mutation among Lebanese patients with lower extremity venous thrombosis. Material and Methods. From January 2003 to January 2011, 283 consecutive Lebanese patients, diagnosed with deep venous thrombosis (DVT by duplex scan, were retrospectively reviewed. FVL mutation was tested among patients with conditions highly suggestive of hypercoagulation states (65 patients. Results. FVL mutation was detected among 56.9% of patients, 68.6% of patients younger than 50 years, and 43.4% of patients older than 50 years (=0.041. FVL mutation was commonly reported in young adults, in patients with pregnancy, estrogen drugs, recurrent DVT, and resistance to anticoagulation. Conclusion. The high rate of FVL mutation observed among Lebanese patients with venous thrombosis is related to the high prevalence of this mutation in the Lebanese population. Thrombophilia screening should be tailored to accommodate a population's risk factor. In countries with high prevalence of FVL, this mutation should be screened among patients younger than 50 years and patients with situations highly suggestive of hypercoagulation states.

    The solid waste generated by artisanal gold mining, with high mercury and gold contents, can be found in several areas in the South America. The present study focused on the tailings of an artisanal gold mine area located in the Brazilian northeastern. Samples of the mine tailings were taken and used to perform a physical and chemical characterization study using X-ray diffraction, scanning electron microscopy, neutron activation, X-ray fluorescence, induced coupled plasma-mass spectrometry, among others analytical methods. The results indicate that the material is composed mainly by quartz and goethite, the characteristic size of the particles (d(50)) is about 150 microm, and the density is close of that of quartz. The main constituents are silicon, iron, and aluminum. The tailings gold content is of about 1.8 mg/kg and the mercury content is of about 10 mg/kg. A remarkable feature of this solid waste is that the gold and mercury are both concentrated in both the fine and the coarse particles, but not in particles of intermediary size. Leaching studies indicated that the tailings are stable in weak organic acids, but soluble in alkaline and aired cyanide solutions, in which 89% of gold and 100% of mercury are extracted in 24 h. Electroleaching experiments, performed using sodium chloride as electrolyte, indicated that mercury and gold are extracted simultaneously and the recovery of both metals can be as high as 70% in 4 h. In addition, chromium, nickel, and lead are found in relatively large amounts in the solution, which indicate an effectively action of the electroleaching method to clean up solid wastes contaminated with metals.

  15. Isolation of Cronobacter spp. (Enterobacter sakazakii from artisanal mozzarella

    Full Text Available Cronobacter spp. (Enterobacter sakazakii is an opportunistic bacterial pathogen capable of causing disease and even fatalities in newborn infants within the first weeks of life if consumed as part of the diet. Premature and immunocompromised newborn infants are at particular risk. The microorganism has been isolated from a variety of foods including contaminated infant milk formula powder and milk powder substitute. The study aimed to evaluate the level of microbiological contamination in 47 samples of mozzarella cheese made with cow’s milk collected from artisan cheese producers in Southern Italy. Samples were collected from commercial sales points and underwent qualitative and quantitative microbiological analyses to test for the bacterial contaminants most commonly found in milk and cheese products. The 47 samples underwent qualitative and quantitative microbiological tests according to ISO UNI EN standards. Analyses focused on Staphylococcus aures, Salmonella spp., Listeria monocytogenes, Pseudomonas spp., E. coli, Yersinia spp., total coliforms and Cronobacter sakazakii. The ISO/TS 22964:2006 method was used to investigate possible contamination by C. sakazakii. Biochemical identification was carried out using an automated system for identification and susceptibility tests. None of the samples examined resulted positive for Salmonella spp. or Listeria spp. Only one sample resulted positive for Staphylococcus aureus. Pseudomonas spp. was isolated in 10 (21% of 47 samples. High levels of total coliforms were found in 10 of 47 samples. Cronobacter spp. (Enterobacter sakazakii was isolated in one sample. This is the first study to confirm isolation of C. sakazakii in artisan mozzarella cheese made from cow’s milk. The presence of C. sakazakii could be related to external contamination during the phases of production or to the use of contaminated milk. Since mozzarella is recommended in the diet of children and adults of all ages, this

    The main aims of this study are to describe the characteristics of the meat pie, a typical product of the regional gastronomy of Murcia and to determine its nutritional and energy values, fatty acid profile and fat quality. There were studied 24 samples of Murcia's meat pie from the six best-selling retail establishments in this Region (four units per establishment).The moisture, protein, fat, carbohydrates, fibre and minerals, contents and the energy value, fatty acid profile and fat quality were analyzed using the Official Analysis Methods of Foods. All analyses were performed by triplicate. The average weight of this product was 192.3 ± 11.8 g, with three differentiated parts (base, filling and pastry lid). All ingredients were natural raw materials: wheat flour, lard, ground beef, sliced boiled egg and chorizo, water and spices (salt, pepper, garlic, paprika and nutmeg). Most of its organoleptic attributes are due to the type and amount of fat or lard. The combination of the other ingredients and the particular formulation of the spices are also responsible of other attributes. Due to its protein content (11.0%), this meat pie can replace other meat dishes, and be incorporated into a balanced diet. However, it is necessary to take into account its fat and energy contents (17.3 g and 317 kcal/100 g, respectively). Unlike many common pastry products, it contains no trans fatty acids. The results of the research show that the studied product remains, at present, an artisan food, and offer reliable information that it is representative of the energy and nutritional values of the Murcia's meat pie, a typical product of the gastronomy of the Region of Murcia.

    This work presents the first study on the bacterial communities in Pico cheese, a traditional cheese of the Azores (Portugal), made from raw cow's milk. Pyrosequencing of tagged amplicons of the V3-V4 regions of the 16S rDNA and Operational Taxonomic Unit-based (OTU-based) analysis were applied to obtain an overall idea of the microbiota in Pico cheese and to elucidate possible differences between cheese-makers (A, B and C) and maturation times. Pyrosequencing revealed a high bacterial diversity in Pico cheese. Four phyla (Firmicutes, Proteobacteria, Actinobacteria and Bacteroidetes) and 54 genera were identified. The predominant genus was Lactococcus (77% of the sequences). Sequences belonging to major cheese-borne pathogens were not found. Staphylococcus accounted for 0.5% of the sequences. Significant differences in bacterial community composition were observed between cheese-maker B and the other two units that participated in the study. However, OTU analysis identified a set of taxa (Lactococcus, Streptococcus, Acinetobacter, Enterococcus, Lactobacillus, Staphylococcus, Rothia, Pantoea and unclassified genera belonging to the Enterobacteriaceae family) that would represent the core components of artisanal Pico cheese microbiota. A diverse bacterial community was present at early maturation, with an increase in the number of phylotypes up to 2 weeks, followed by a decrease at the end of ripening. The most remarkable trend in abundance patterns throughout ripening was an increase in the number of sequences belonging to the Lactobacillus genus, with a concomitant decrease in Acinetobacter, and Stenotrophomonas. Microbial rank abundance curves showed that Pico cheese's bacterial communities are characterized by a few dominant taxa and many low-abundance, highly diverse taxa that integrate the so-called "rare biosphere".

    Cardiac disease is the leading cause of death in Lebanon, accounting for 22% to 26% of total deaths in the country. A thorough understanding of perceptions of cardiac illness and related self-care management is critical to the development of secondary prevention programs that are specific to the Lebanese culture. To explore the cultural perceptions of cardiac illness and the associated meaning of self-care among Lebanese patients. Using a qualitative descriptive method, semistructured interviews were conducted with a purposive sample of 15 Lebanese cardiac patients recruited from a medical center in Beirut, Lebanon. The qualitative descriptive analysis yielded one overarching and two other themes describing perceptions of cardiac illness and self-care within the Lebanese cultural context. The overarching cultural theme was, "Lebanese cardiac patients were unfamiliar with the term concept and meaning of self-care." Lebanese cardiac patients thanked God and accepted their fate (Theme I). The participants considered their cardiac incident a life or death warning (Theme II). Health care providers need to consider patients' cultural perception of illness while planning and evaluating cardiac self-care programs. © The Author(s) 2015.

    Highlights: • We simulated artisanal incineration of four component categories of cellphones. • We identified metals and organic chemicals in the resulting electronic waste ash. • We used USETox model to demonstrate potential ecotoxicity and human health impacts. • We identify targets for risk reduction for hazardous chemicals in cellphones. - Abstract: The potential environmental and human health impacts of artisanal mining of electronic waste through open incineration were investigated. A market-representative set of cellphones was dismantled into four component categories—batteries, circuit boards, plastics and screens. The components were shredded, sieved and incinerated at 743–818 °C. The concentrations of 17 metals were determined using U.S. EPA methods 6010C (inductively coupled plasma-atomic emission spectrometry; 6020A (inductively coupled plasma-mass spectrometry, or 7471B and 7470A (cold-vapor atomic absorption). EPA Method 8270 (gas chromatography/mass spectrometry) was used to identify polyaromatic hydrocarbon compounds and polybrominated diphenyl ethers. EPA Method 8082A was used to measure polychlorinated biphenyls and EPA Method 8290 was used for dioxin/furans in the residue ash. The life cycle assessment model USEtox{sup ®} was used to estimate impacts of the ash residue chemicals on human health and the ecosystem. Among metals, copper in printed circuit boards had the highest ecotoxicity impact (1610–1930 PAF m{sup 3}/kg); Beryllium in plastics had the highest impact on producing non-cancer diseases (0.14–0.44 cases/kg of ash); and Nickel had the largest impact on producing cancers (0.093–0.35 cases/kg of ash). Among organic chemicals, dioxins from incinerated batteries produced the largest ecotoxicological impact (1.07E − 04 to 3.64E − 04 PAF m{sup 3}/kg). Furans in incinerated batteries can generate the largest number of cancers and non-cancer diseases, representing 8.12E − 09 to 2.28E − 08 and 8.96E − 10 and 2.52E

    Full Text Available Traps are used by artisanal fishers as fishing gear in places where other fishing modalities are impeded or limited. The advantage of this type of fishing modality is the possibility of keeping fish alive and in the case of capturing species of low commercial value or size below the permitted minimum this fishing gear allows the release of such specimens back to nature, resulting in a sustainability aspect to the use of this fishing gear. This study aims to evaluate the effects of different attractors and times of submersion on the efficiency of the traps used. Sardines, shrimps and trash fish were employed as attractors. To evaluate the soak time, two periods were tested: 24 and 96 hours. The sardines, used as the attractor, resulted in a production of 1,296.4 ± 397.4g, significantly superior (p <0.05 to other attractors. In relation to the soak time, the period of 24 hours resulted in an average production of 1,719.2 ± 866.0g, significantly (p <0.05 superior to the period of 96 hours. The results led to the conclusion that to optimize this capture by fishing gear, sardines should be used as the attractor, together with a soak time of 24 hours.

    Full Text Available The aim of this study was to evaluate some physical and chemical parameters (total solids, pH, acidity, fat, acid degree value of fat, salt, protein and nitrogen fractions and their effects on the beneficial (lactic acid bacteria: LAB and undesirable microbial populations (coliforms, Escherichia coli, Staphylococcus aureus, moulds, and yeast during ripening of Artisanal Corrientes Cheese, an Argentinian cow's milk variety, to determine whether a longer ripening period than usual improve its hygienic-sanitary quality. The protein content was much higher than that of other cow's milk cheeses with similar values of fat. The larger peptides showed values three times higher in the 30 day-old cheese than those obtained in the beginning of the process. Staphylococcus aureus and Escherichia coli were detected (3.04 ± 1.48 log10 cfu/g of cheese, 2.21 ± 0.84 log10 MPN/g of cheese even at 15 and 30 days of ripening, respectively. The distribution of three hundred LAB strains classified to the genus level (lactococci:lactobacilli:leuconostocs was maintained during the ripening period. The high number of LAB in rennet may have contributed to the fermentation as a natural whey starter, unknown source of LAB for this specific cheese so far. The physicochemical changes that occur during ripening were not big enough to inhibit the growth of undesirable microorganisms.

    Solar salinas are man-made systems exploited for the extraction of salt, by solar and wind evaporation of seawater. Salt production achieved by traditional methods is associated with landscapes and environmental and patrimonial values generated throughout history. Since the mid-twentieth century, this activity has been facing a marked decline in Portugal, with most salinas either abandoned or subjected to destruction, making it necessary to find a strategy to reverse this trend.It is, however, possible to generate revenue from salinas at several levels, not merely in terms of good quality salt production, but also by obtaining other products that can be commercialized, or by exploring their potential for tourism, and as research facilities, among others. Furthermore, with an adequate management, biodiversity can be restored to abandoned salinas, which constitute important feeding and breeding grounds for resident and migratory aquatic birds, many of which are protected by European Community Directives.The aims of this manuscript are to present a brief overview on the current state of sea salt exploitation in Portugal and to stress the importance of recovering these salinas for the conservation of this particular environment, for the regional economy, the scientific community and the general public. The Aveiro salina complex is presented in detail, to exemplify salina structure and functioning, as well as current problems and potential solutions for artisanal salinas.

    The present study characterises the commercial fisheries of the basin of the Xingu River, a major tributary of the Amazon River, between the towns of Gurupá (at the mouth of the Amazon) and São Félix do Xingu. Between April, 2012, and March, 2014, a total of 23,939 fishing trips were recorded, yielding a total production of 1,484 tons of fish, harvested by almost three thousand fishers. The analysis of the catches emphasizes the small-scale and artisanal nature of the region's fisheries, with emphasis on the contribution of the motorised canoes powered by "long-tail" outboard motors. Larger motorboats operate only at the mouth of the Xingu and on the Amazon. Peacock bass (Cichla spp.), croakers (Plagioscion spp.), pacu (a group containing numerous serrasalmid species), aracu (various anostomids), and curimatã (Prochilodus nigricans) together contributed more than 60% of the total catch. Mean catch per unit effort was 18 kg/fisher-1.day-1, which varied among fishing methods (type of vessel and fishing equipment used), river sections, and time of the year. In most cases, yields varied little between years (2012 and 2013). The technical database provided by this study constitutes an important resource for the regulation of the region's fisheries, as well as for the evaluation of future changes resulting from the construction of the Belo Monte dam on the Xingu River.

    In Mongolia, artisanal gold mining, modern gold rush, in which people use mercury to extract gold, is being proliferated rapidly and the mercury contamination of mining site is becoming a serious social issue. For the risk assessment of mercury, it is necessary to understand how much mercury is introduced to the environment from what kind of materials during mining activity. It is already known that major contribution of the contamination comes from mercury that was bought at shops and brought to mining sites by miners. However, no information is available on how much mercury is removed from electrum (natural gold grain) to the environment. Since gold deposit is always accompanied by mercury anomaly, it is anticipated that electrum grains contain some amount of mercury of natural origin, and this mercury (primary mercury) contributes to some extent to the contamination. In order to clarify how much mercury is incorporated in electrum grains, micro-PIXE at CSIRO was used for grain-by-grain analysis. The result showed that electrum from study area contains mercury up to 8260 ppm. It is concluded that for the risk management of mercury contamination, release of natural mercury from electrum grains during smelting must not be ignored.

    In the context of a worldwide physician brain drain phenomenon, Lebanon has the highest emigration factor in the Middle East and North Africa. In this manuscript we aim to identify and develop a conceptual framework for the factors underlying the decisions of graduating Lebanese medical students to train abroad. We conducted two focus groups and seven semi-structured individual interviews with 23 students. In the deductive analysis (based on the push-pull theory), students reported push factors in Lebanon and pull factors abroad related to five dimensions. They focused predominantly on how training abroad provides them with a competitive advantage in an oversaturated Lebanese job market. An inductive analysis revealed the following emerging concepts: repel factors abroad and retain factors locally; societal expectations that students should train abroad; marketing of abroad training; and an established culture of migration. The marketing of abroad training and the culture of migration are prevalent in the academic institutions.

    Full Text Available The Lebanese Shouf Biosphere Reserve (SBR counts among the most successful Middle Eastern conservation projects today. This article describes the evolution and contemporary management of conservation in Shouf. Using SBR as the empirical foci it argues that mobilisation of customary political hierarchies to secure environmental protection is not bound to impede conservation agendas as suggested by Kingston (2001, but rather provided the SBR with managerial flexibility under a weak state. The case study shows how new environmental agendas articulated with traditional political regimes in building novel, stable institutions. From these emerged contextually flexible solutions for mediating resources and negotiating nature. The Shouf′s particular clientelist political structure gave rise to networks simultaneously civic and part of the Lebanese state. Explaining the apparent stability of conservation practice in Shouf requires shifting analytical frames away from polarised debates either for or against the roles of state, civil society, and patronage in conservation.

    To monitor the effect of the indigenous milk microbiota and of technological and environmental parameters on the microbiota established in ripened cheese, the diversity and dynamics of the predominant microbial communities in artisan Gouda-type cheeses produced under different conditions was studied. A total of 22 cheese types differing in milk source, milk treatment, production environment and brining conditions were analyzed by PCR-denaturing gradient gel electrophoresis (PCR-DGGE) using total DNA extracts as well as DNA extracted from culturable fractions. Through band position analysis and band sequencing, the majority of DGGE bands could be attributed to lactic acid bacteria (LAB), although a few bands also belonged to staphylococci and gamma-Proteobacteria. Aided by principal component analysis (PCA) and multivariate analysis of variance (MANOVA), cheeses produced at different locations could clearly be differentiated. The same approach also allowed to distinguish raw and pasteurized milk cheeses, the former showing a more diverse microbiota in terms of a higher species richness and number of DGGE bands. No substantial differences were found between cheeses brined at two different locations. In conclusion, the combined PCR-DGGE approach relying on both total DNA extracts and culturable fractions proved its value for analyzing the effect of technological and environmental parameters on the diversity and dynamics of the microbiota in Gouda-type cheeses.

    The microbiota associated with a highly-perishable Belgian artisan-type cooked ham was analyzed through plating and (GTG)(5)-fingerprinting of isolates throughout its processing chain. The raw tumbled meat was characterized by the presence of a versatile microbiota around 4.8 log(cfu g(-1)), consisting of lactic acid bacteria, staphylococci, Brochothrix thermosphacta, Gram-negative bacteria, and yeasts. Pasteurisation of the ham logs reduced bacterial counts below 2 log(cfu g(-1)) and subsequent manipulations selected for leuconostocs and carnobacteria. Also, B. thermosphacta and several Enterobacteriaceae were found at this stage. During storage in an intermediate high-care area for 2 days, a selection towards certain Enterobacteriaceae (Hafnia alvei, Enterobacter spp., and Pantoea agglomerans) and lactic acid bacteria (mainly vagococci and Streptococcus parauberis) was observed. B. thermosphacta, Leuconostoc carnosum and carnobacteria were also detected, but only after allowing bacterial outgrowth by incubating the meat logs at 7 degrees C for four weeks. After a mild post-pasteurisation process and subsequent handling, incubation of the meat logs at 7 degrees C for four weeks led to outgrowth of Enterobacteriaceae (mainly Enterobacter spp. and Serratia spp.). B. thermosphacta, and lactic acid bacteria (Enterococcus faecalis, Leuc. carnosum, and Carnobacterium maltaromaticum) were also found. After slicing and packaging under modified atmosphere, the microbiota of the refrigerated end-product consisted of leuconostocs, carnobacteria, and B. thermosphacta.

    Objective: The aim of this study was to evaluate the length of the greater palatine canal in a Lebanese population using cone-beam computed tomography (CBCT) technology. Material and methods: In this study, we measured the length of 148 greater palatine canals in 74 CBCT images of Lebanese adult patients (38 females and 36 males). The data obtained was analyzed statistically to determine 1) if age is related to the length of the canal, 2) if the length of the left side tends to be systematically larger or smaller than the length of the right side, and 3) if the mean length of the canals in females is different than the one in males. Results: In a sagittal plane, the average length of the greater palatine canal was 30.62 (30.64 mm on the right and 30.60 mm on the left). Conclusion: Within the limits of this study, we concluded that in our sample in a Lebanese population, the length of the greater palatine canal does not significantly vary according to age, gender, and side.

    Polychlorinated biphenyls (PCBs) are persistent organic pollutants that are still routinely detected 30 years after their restriction in many countries. PCBs have been associated with several non-communicable diseases. They are best measured via human biomonitoring (HBM). The concentrations of six indicator PCBs (PCBs 28, 52, 101, 138, 153, and 180) were measured in the serum samples of 316 Lebanese students and employees from Saint Joseph University of Beirut, Lebanon, using gas chromatography coupled to an iron trap mass spectrometer detector. PCBs were detected in 56.3 to 59.2% of the serum samples. The sum of PCB (∑PCBs) levels ranged from food contributors, we found no relation between PCB levels and fish consumption and a moderate relation with dairy product consumption (moderate consumers of dairy products had higher PCB levels compared to lower consumers) (16.92 ± 0.1/6.92 ± 0.12; p = 0.025). The present study is the first to provide information regarding PCB levels in a Lebanese population. Larger studies are required in order to estimate the PCB exposure parameters of the Lebanese population.

  15. The transformation of Lebanese firms from ISO 9000 certified to TQM.

    2000-01-01

    Over the past decade, the most effective method of implementing a quality system has been ISO 9000 certification. Lebanese companies have recently followed the same path of adopting and improving their status in quality systems. The overwhelming belief is that ISO 9000 is, by itself, not enough. It is a first stepping-stone in the road to business excellence, but ISO 9000 does not guarantee an improvement in the product or service being offered. All indications are that Total Quality Management (TQM) is the method for improving quality as a whole. This improvement is, of course, entirely reliant on the proper implementation and understanding of the scope and underlying objectives. The relatively new adoption of TQM as an effective tool in the struggle to achieve substantial improvements in quality is made clear in the results of a survey that are presented in this article. Recommendations as how to make the transition between ISO 9000 and TQM are made, and a discussion is provided of the need for organizational change, both internal and external, within companies in the Lebanese market. The aim of this work is to present a clear representation of what is actually occurring within the Lebanese domestic market with regards to the understanding the TQM philosophy.

    This article presents an analysis of how scientists are portrayed in the Lebanese national science textbooks. The purpose of this study was twofold. First, to develop a comprehensive analytical framework that can serve as a tool to analyze the image of scientists portrayed in educational resources. Second, to analyze the image of scientists portrayed in the Lebanese national science textbooks that are used in Basic Education. An analytical framework, based on an extensive review of the relevant literature, was constructed that served as a tool for analyzing the textbooks. Based on evidence-based stereotypes, the framework focused on the individual and work-related characteristics of scientists. Fifteen science textbooks were analyzed using both quantitative and qualitative measures. Our analysis of the textbooks showed the presence of a number of stereotypical images. The scientists are predominantly white males of European descent. Non-Western scientists, including Lebanese and/or Arab scientists are mostly absent in the textbooks. In addition, the scientists are portrayed as rational individuals who work alone, who conduct experiments in their labs by following the scientific method, and by operating within Eurocentric paradigms. External factors do not influence their work. They are engaged in an enterprise which is objective, which aims for discovering the truth out there, and which involves dealing with direct evidence. Implications for science education are discussed.

    Lebanon is witnessing an increased emigration of physicians. The objective of this study was to understand the perceptions of Lebanese policymakers of this emigration, and elicit their proposals for future policies and strategies to deal with this emigration. We conducted semi-structured individual interviews with the deans of Lebanon's seven medical schools, the presidents of the two physicians professional associations, and governmental officials. We analyzed the results qualitatively. Participants differed in the assessment of the extent and gravity of emigration. Lebanon has a surplus of physicians, driven largely by the over-production of graduates by a growing number of medical schools. Participants cited advantages and disadvantages of the emigration on the personal, financial, medical education system, healthcare system, and national levels. Proposed strategies included limiting the number of students entering medical schools, creating job opportunities for graduating students, and implementing quality standards. Most participants acknowledged the globalization of the Lebanese physician workforce, including exchanges with the Gulf region, exchanges with developed countries, and the involvement of North American medical education institutions in the region. Many Lebanese policy makers, particularly deans of medical schools, perceive the emigration of the physician workforce as an opportunity in the context of the globalization of the profession.

    Full Text Available Implantation of iris-claw Artisan intraocular lens (IOL is a surgical option for correction of aphakia; however, these IOLs have not been used in eyes with uveitis including Fuchs′ heterochromic iridocyclitis (FHI due to possible risk of severe postoperative intraocular inflammation. In the case reported here, we secondarily implanted an Artisan IOL in a 28-year-old man with FHI who had aphakia with no capsular support due to a previous complicated cataract surgery. Enclavation was easily performed and no intraoperative complication was noted. Postoperative course was uneventful with no significant anterior chamber inflammation during 12 months of follow-up. Although there were few deposits on the IOL surface, the patient achieved a best-corrected visual acuity of 20/20 without developing glaucoma or other complications. Therefore, Artisan IOL may be considered for correction of aphakia in patients with FHI. However, studies on large number of patients are required to evaluate safety of the procedure.

    This paper reviews what is known about the problems and structural challenges facing the 20-30 million artisanal and small-scale miners and their communities worldwide. Better understanding of these structural challenges is needed to improve policies and policy implementation to further sustainable development opportunities for the sector. The paper explores the current gaps in knowledge to achieve policy change from researchers, practitioners and artisanal and small-scale miners themselves. It explores how a 'knowledge intermediary', which acts to link knowledge with policy, could address these gaps and includes case studies of IIED’s work on knowledge networks and programmes. The paper concludes by proposing a way forward for designing a knowledge programme to meet the particular needs of the artisanal and small-scale mining (ASM) sector, and by inviting ASM sector stakeholders to share their views on the options outlined.

  1. LIVE/DEAD YEAST VIABILITY STAINING AS A TOOL FOR IMPROVING ARTISANAL PILSNER BEER PRODUCTION

    Directory of Open Access Journals (Sweden)

    Benedetta Bottari

    2014-10-01

    Full Text Available The production of an artisanal beer, made by brewers using traditional practices on a small scale, is founded on the empirical adjustment of parameters, including yeasts handling and serial repitching. The aim of this study was to monitor yeast viability during different stages of artisanal beer productions through the Live/Dead Yeast viability staining and to correlate it with fermentation dynamics in order to increase process standardization and to maintain the quality of final products. Yeast viability and fermentation activities were evaluated during seven fermentation cycles of an artisanal pilsner beer. Yeast inoculated with higher viability performed generally better in fermentation, resulting in faster sugar consumption, faster ethanol production and stability. Handling yeast and serial repitching based on Live/Dead viability measurements, could be the key way to ensure reliable manufacture of high quality beer and to improve process standardization particularly for microbreweries, where variability of production can be a challenging point.

    The artisanal fisheries of Ecuador operate within one of the most dynamic and productive marine ecosystems of the world. This study investigates the catch composition of the Ecuadorian artisanal fishery for large pelagic fishes, including aspects of its spatio-temporal dynamics. The analyses of this study are based on the most extensive dataset available to date for this fishery: a total of 106,963 trip-landing inspection records collected at its five principal ports during 2008 ‒ 2012. Ecuadorian artisanal fisheries remove a substantial amount of biomass from the upper trophic-level predatory fish community of the eastern tropical Pacific Ocean. It is estimated that at least 135 thousand metric tons (mt) (about 15.5 million fish) were landed in the five principal ports during the study period. The great novelty of Ecuadorian artisanal fisheries is the "oceanic-artisanal" fleet component, which consists of mother-ship (nodriza) boats with their towed fiber-glass skiffs (fibras) operating with pelagic longlines. This fleet has fully expanded into oceanic waters as far offshore as 100°W, west of the Galapagos Archipelago. It is estimated that nodriza operations produce as much as 80% of the total catches of the artisanal fishery. The remainder is produced by independent fibras operating in inshore waters with pelagic longlines and/or surface gillnets. A multivariate regression tree analysis was used to investigate spatio-environmental effects on the nodriza fleet (n = 6,821 trips). The catch species composition of the nodriza fleet is strongly influenced by the northwesterly circulation of the Humboldt Current along the coast of Peru and its associated cold waters masses. The target species and longline gear-type used by nodrizas change seasonally with the incursion of cool waters (Coryphaena hippurus) dominates the catches. However, in warmer waters, the fishery changes to tuna-billfish-shark longline gear and the catch composition becomes much more diverse.

    Full Text Available In a study using three replicates, Marzolina goat cheese made with artisanal rennet paste from goat kid was compared with cheese made with commercial liquid rennet from calf. Samples of fresh cheese were subjected to chemical and microbiological analyses. Samples of ripened cheese collected after 50 days of ripening were submitted to chemical and sensory analysis. Results of this study show that cheese made with artisanal rennet pastes did not contain pathogenic microorganisms and that this kind of rennet provided the enzymatic content necessary to achieve the typical characteristics of traditional cheeses.

    The potential environmental and human health impacts of artisanal mining of electronic waste through open incineration were investigated. A market-representative set of cellphones was dismantled into four component categories-batteries, circuit boards, plastics and screens. The components were shredded, sieved and incinerated at 743-818 °C. The concentrations of 17 metals were determined using U.S. EPA methods 6010C (inductively coupled plasma-atomic emission spectrometry; 6020A (inductively coupled plasma-mass spectrometry, or 7471B and 7470A (cold-vapor atomic absorption). EPA Method 8270 (gas chromatography/mass spectrometry) was used to identify polyaromatic hydrocarbon compounds and polybrominated diphenyl ethers. EPA Method 8082A was used to measure polychlorinated biphenyls and EPA Method 8290 was used for dioxin/furans in the residue ash. The life cycle assessment model USEtox(®) was used to estimate impacts of the ash residue chemicals on human health and the ecosystem. Among metals, copper in printed circuit boards had the highest ecotoxicity impact (1610-1930PAFm(3)/kg); Beryllium in plastics had the highest impact on producing non-cancer diseases (0.14-0.44 cases/kg of ash); and Nickel had the largest impact on producing cancers (0.093-0.35 cases/kg of ash). Among organic chemicals, dioxins from incinerated batteries produced the largest ecotoxicological impact (1.07E-04 to 3.64E-04PAFm(3)/kg). Furans in incinerated batteries can generate the largest number of cancers and non-cancer diseases, representing 8.12E-09 to 2.28E-08 and 8.96E-10 and 2.52E-09 cases/kg of ash, respectively. The results reveal hazards of burning discarded cellphones to recover precious metals, and pinpoints opportunities for manufacturers to reduce toxic materials used in specific electronic components marketed globally.

    Full Text Available The burrata cheese is a traditional product from Southern Italy, consisting of an envelope of pasta filata (stretched curd filled with cream and pasta filata strips (usually leftovers from mozzarella production. Physical [water activity (aw, pH], chemical (moisture, NaCl content and microbiological [total viable count (TVC, Listeria monocytogenes, Salmonella spp., Yersinia enterocolitica, Bacillus cereus, Escherichia coli, Enterobacteriaceae, coagulase-positive staphylococci] characteristics of burrata cheeses manufactured in artisanal and industrial plants were evaluated. The artisanal burrata showed lower aw values in the filling and the final product. The same was recorded in the filling for the moisture, probably due to differences between the types of cream used in the artisanal and the industrial cheesemaking. The pH value of the filling differed between the two groups but no difference was recorded in the final product. Microbiological differences were also recorded, with higher values for TVC and E. coli in artisanal than industrial burrata. All samples were negative for the other microbial determinations, with the exception of coagulase-positive staphylococci and Y. enterocolitica, which were detected in artisanal burrata. Differences in cheesemaking process were probably responsible for the strong variability of the physical and chemical data between the two cheeses; furthermore, differences in the hygienic features were also recorded. Even though artisanal products showed lower aw and pH values and higher NaCl concentration, the higher E. coli loads highlighted the need for a more accurate compliance with hygienic procedures along the artisanal cheesemaking process.

    The widespread patient use of artisanal cannabis preparations has preceded quality validation of cannabis use for epilepsy. Neurologists and cannabinoid specialists are increasingly in a position to monitor and guide the use of herbal cannabis in epilepsy patients. We report the retrospective data on efficacy and adverse effects of artisanal cannabis in Patients with medically refractory epilepsy with mixed etiologies in Washington State, California, and Maine. Clinical considerations, including potential risks and benefits, challenges related to artisanal preparations, and cannabinoid dosing, are discussed. Of 272 combined patients from Washington State and California, 37 (14%) found cannabis ineffective at reducing seizures, 29 (15%) experienced a 1-25% reduction in seizures, 60 (18%) experienced a 26-50% reduction in seizures, 45 (17%) experienced a 51-75% reduction in seizures, 75 (28%) experienced a 76-99% reduction in seizures, and 26 (10%) experienced a complete clinical response. Overall, adverse effects were mild and infrequent, and beneficial side effects such as increased alertness were reported. The majority of patients used cannabidiol (CBD)-enriched artisanal formulas, some with the addition of delta-9-tetrahydrocannabinol (THC) and tetrahydrocannabinolic acid (THCA).

    Full Text Available Introduction: This study focuses on accidents in artisanal mining, to support policies improving miners' employability. Materials and Methods: Based on a questionnaire administered in November 2009 to a sample of 180 miners from the artisanal mining of LUPOTO, in the Province of Katanga, we explored significant trends between the accidents and their consequences and behavioral or sociological variables. Results: During the 12 months preceding the study, 392 accidents occurred, affecting 72.2% of miners. Tools handling represents 51.5%, of the accidents' causes, followed by handling heavy loads (32.9%. Factors such as age, seniority or apprenticeship did not generate significant differences. Contusions were the most common injuries (50.2%, followed by wounds (44.4%. These injuries were located in upper limbs (50.5% and in lower limbs (29.3%. 80.5% of miners were cared for by their colleagues and 50% of them could not work for more than 3 days. Physical sequelae were reported by 19% of the injured miners. Discussion: Many surveys related to accidents in the area of artisanal mining report such high frequency. The unsuitability of tools to jobs to be done is usually raised as one of the major causes of accidents. The lack of differentiation of the tasks carried out in relation to age is another factor explaining the lack of protective effect of seniority as it minimizes the contribution of experience in the worker's safety. The apprenticeship reported is inadequate; it is rather a learning by doing than anything else. That is why it lacks protective effect. Low income combined with precariousness of artisanal mining are likely to explain the low level of work stoppages. Conclusion: Tools improvement associated with adequate training seem to be the basis of accident prevention. Availability of suitable medical care should improve artisanal miners' recovery after accidents.

    The aims of this study are to establish reference values for TSH in Lebanese schoolchildren; to look at the relationship between TSH and age, gender, BMI, socioeconomic status (SES), and thyroid antibodies (TAb); and to investigate the prevalence of abnormal TAb in this population. 974 Lebanese schoolchildren aged 8–18 years were recruited from 10 schools of different SES. Third-generation TSH, TPO-Ab, and Tg-Ab measurements were performed using the IMMULITE chemiluminescent immunoassay. The mean TSH is 2.06 ± 1.05 μUI/ml. TSH values are inversely correlated with age (p < 0.0001), are higher in boys than in girls (resp., 2.14 ± 1.10 and 1.98 ± 0.99 μUI/ml, p = 0.017), and are positively correlated with BMI (p < 0.0001). They are also significantly higher in subjects from low-SES schools (p = 0.03) and in girls with positive TAb (p = 0.026). In boys, TSH is independently associated with age, BMI, and schools' SES (p = 0.01, p = 0.03, and p = 0.026, resp.) while in girls, the association is only significant for age and TAb (p = 0.0001 and p = 0.015, resp.). The prevalence of TAb is 4.3% (3% for TPO-Ab and 2.1% for Tg-Ab). Our results showed higher TSH values in the pediatric Lebanese population compared to western populations. TSH varies according to age, gender, BMI, and SES and is associated in girls with TAb. PMID:28250769

    Full Text Available Abstract Background The international migration of physicians is a global public health problem. Lebanon is a source country with the highest emigration factor in the Middle East and North Africa and the 7th highest in the World. Given that residency training abroad is a critical step in the migration of physicians, the objective of this study was to survey students of Lebanese medical schools about their intentions to train abroad and their post training plans. Methods Our target population consisted of all students of Lebanese medical schools in the pre-final and final years of medical school. We developed the survey questionnaire based on the results of a qualitative study assessing the intentions and motives for students of Lebanese medical schools to train abroad. The questionnaire inquired about student's demographic and educational characteristics, intention to train abroad, the chosen country of abroad training, and post-training intention of returning to Lebanon. Results Of 576 eligible students, 425 participated (73.8% response rate. 406 (95.5% respondents intended to travel abroad either for specialty training (330 (77.6% or subspecialty training (76 (17.9%. Intention to train abroad was associated with being single compared with being married. The top 4 destination countries were the US (301(74.1%, France (49 (12.1%, the United Kingdom (31 (7.6% and Canada (17 (4.2%. One hundred and two (25.1% respondents intended to return to Lebanon directly after finishing training abroad; 259 (63.8% intended to return to Lebanon after working abroad temporarily for a varying number or years; 43 (10.6% intended to never return to Lebanon. The intention to stay indefinitely abroad was associated male sex and having a 2nd citizenship.

    Anti-N-methyl-D-aspartate (NMDA) receptor encephalitis is a recently recognized autoimmune neurologic disorder that presents with severe neuropsychiatric symptoms in previously healthy children. A 4-year-old Lebanese girl presented with new-onset behavioral changes, orofacial dyskinesias, fluctuation in consciousness, inability to walk, and mutism. Antibodies directed against NMDA receptors were detected in the patient's serum and cerebrospinal fluid. Prompt treatment with a single course of intravenous immunoglobulin resulted in early complete recovery. This is the first case report of a Middle Eastern child affected with this condition.

    Coagulase-negative staphylococci (CNS) that are naturally present in the raw meat batter of fermented sausages or that originate from the addition of a starter culture play a role in flavour development. A wide species diversity of CNS can be present in fermented meats, but it is not fully clear yet how specific process parameters select for specific CNS by affecting their community dynamics. Therefore, the influence of smoking and moulding treatments on the CNS community dynamics in spontaneously fermented, artisan-type sausages was investigated. During the fermentation stage, the meat batter was in all cases dominated by Staphylococcus saprophyticus, in addition to Lactobacillus sakei as governing lactic acid bacterium. Following fermentation, the bacterial communities were not perturbed by the smoking treatment, since both L. sakei and S. saprophyticus remained dominant throughout the ripening stage and prevailed in the end-products. Yet, when fermentation was followed by a moulding step with Penicillium nalgiovense, a shift of the CNS communities towards dominance by Staphyloccocus equorum was seen, despite a similar evolution of L. sakei. This effect was possibly due to a pH rise caused by the mould, a hypothesis which was reinforced by the finding that the isolated strain S. equorum DBX-S-17 was more sensitive to low pH than the isolated strain S. saprophyticus DFL-S-12 during growth experiments in brain heart infusion (BHI). Differences in CNS communities may affect sausage flavour, due to intraspecies variations in metabolic conversions of, for instance, amino acids. The fact that 3-methyl-butanal was only found in the moulded sausage, which was dominated by S. equorum, may be related to the finding that the isolated strain of this species was able to produce this compound in BHI medium, whereas the isolated strain of S. saprophyticus was not.

  7. The Ecuadorian Artisanal Fishery for Large Pelagics: Species Composition and Spatio-Temporal Dynamics.

    Full Text Available The artisanal fisheries of Ecuador operate within one of the most dynamic and productive marine ecosystems of the world. This study investigates the catch composition of the Ecuadorian artisanal fishery for large pelagic fishes, including aspects of its spatio-temporal dynamics. The analyses of this study are based on the most extensive dataset available to date for this fishery: a total of 106,963 trip-landing inspection records collected at its five principal ports during 2008 ‒ 2012. Ecuadorian artisanal fisheries remove a substantial amount of biomass from the upper trophic-level predatory fish community of the eastern tropical Pacific Ocean. It is estimated that at least 135 thousand metric tons (mt (about 15.5 million fish were landed in the five principal ports during the study period. The great novelty of Ecuadorian artisanal fisheries is the "oceanic-artisanal" fleet component, which consists of mother-ship (nodriza boats with their towed fiber-glass skiffs (fibras operating with pelagic longlines. This fleet has fully expanded into oceanic waters as far offshore as 100°W, west of the Galapagos Archipelago. It is estimated that nodriza operations produce as much as 80% of the total catches of the artisanal fishery. The remainder is produced by independent fibras operating in inshore waters with pelagic longlines and/or surface gillnets. A multivariate regression tree analysis was used to investigate spatio-environmental effects on the nodriza fleet (n = 6,821 trips. The catch species composition of the nodriza fleet is strongly influenced by the northwesterly circulation of the Humboldt Current along the coast of Peru and its associated cold waters masses. The target species and longline gear-type used by nodrizas change seasonally with the incursion of cool waters (< 25°C from the south and offshore. During this season, dolphinfish (Coryphaena hippurus dominates the catches. However, in warmer waters, the fishery changes to tuna

    . The concepts of raw art and outsider art were typical of a time when oppositional politics still infused artistic and academic discourses. But modernity seems to have ‘grown out’ of its adolescence, so to speak: out of politics of opposition and absolutes. Of course, it is neither desirable nor possible...... to return to the oppositional dynamics and binary divisions of yesterday, now that we have crossed this paradigmatic threshold. But the schizoanalytic stance may offer us another view of the emerging paradigm. It affords different tools of interpretation and suggests ways artists may grow out of modernity...

    Aiming to evaluate the effects of organic pollution, environmental parameters and phytoplankton community were monitored during a two-year period (from April 2010 till March 2012) in the central coast of Lebanon in the Levantine Sub-basin. Data were collected for hydrological (temperature and salinity), chemical (nitrites, nitrates and phosphates), and biological (chlorophyll-a and phytoplankton populations) parameters. Our results show that temperature follows its normal seasonal and annual cycles, usually noted in the Lebanese coastal waters. Salinity presents spatial and temporal variations with low values (19.07 - 39.6) in the areas affected by continental inputs. Significant fluctuations (P total phytoplanktonic cells were observed between the sites and through the years. Moreover, a perturbation of the natural phytoplanktonic succession and an occurrence of toxic or potentially harmful algae were noticed in the polluted sites, reflecting the influence of wastewater effluents on the coastal seawater equilibrium and thus on the Lebanese marine biodiversity. This study sheds the light on the current environmental condition of few coastal areas which could facilitate the management of their pollution sources.

    Very little information is available on the characteristics of the Lebanese olive germplasm. Therefore, the aim of this work was to evaluate the fruit and oil characteristics of the main Lebanese olive varieties (Aayrouni, Abou chawkeh, Baladi, Del and Soury) from two successive crop seasons (2010-2011). All of the genotypes had medium-high oil content in the fruit, indicating their suitability for oil production; Aayrouni had particularly high values. The variety Abou chawkeh also had a high pulp/pit ratio, which is a very desirable trait in table olives. For all the varieties the values of free fatty acids, peroxide values, absorbances in ultraviolet, fatty acid composition, sterol content and composition and erythrodiol + uvaol content of the oils were within the requirements of the International Olive Council's Trade Standard for extra virgin olive oil. The only exception was for the values of Δ-7-stigmastenol in 2011 in Soury and, especially, in Baladi, which were higher than 0.5%. In some cases, stearic and arachidic acids fluctuated around the maximum values allowed. The findings of this study provide a first picture of the main characteristics of olives and oils currently produced in Lebanon. © 2015 Society of Chemical Industry. © 2015 Society of Chemical Industry.

    In Middle-Eastern countries, more particularly in Lebanon, the incidence of vitamin D deficiency has been found to be surprisingly high in schoolchildren and young individuals. However, the prevalence and risk factors for vitamin D inadequacy amongst Lebanese osteoporotic women seeking medical health care has never been studied. We analysed vitamin D-inadequacy risk factors among the 251 Lebanese postmenopausal osteoporotic women (from both Muslim and Christian communities) who participated in a vitamin D international epidemiological study. Vitamin D inadequacy prevalence (25-hydroxyvitamin D (25(OH)D) , 30 ng/ml) was 84.9%. 25(OH)D was negatively correlated with BMI (r 20.41; Pdress code covering the arms (Pdress code covering the arms are the independent predictors of 25(OH)D inadequacy (P<0.001 for both variables). However, in Christians, the predictors are inadequate vitamin D supplements, high BMI and low educational level (P<0.001; P=002 and P=0.02 respectively). There is an urgent need to increase vitamin D supplement use in Middle-Eastern osteoporotic women, more particularly in those from the Muslim community.

    This research attempts to provide an understanding of the Lebanese pharmaceutical industries' environmental management strategies, priorities, and perceptions as well as drivers, barriers, and incentives regarding the implementation of the voluntary ISO 14001 Environmental Management System. Accordingly, a semistructured in-depth interview was conducted with the pharmaceutical industries. The findings revealed a significant lack of knowledge about the standard among the industries. The main perceived drivers for adopting the ISO 14001 are improving the companies' image and overcoming international trade. The main perceived barriers for acquiring the standard are the lack of government support and the fact that ISO 14001 is not being legally required or enforced by the government. Moreover, results revealed that adopting the ISO 14001 standard is not perceived as a priority for the Lebanese pharmaceutical industries. Although the cost of certification was not considered as a barrier for the implementation of ISO 14001, the majority of the pharmaceutical industries are neither interested nor willing to adopt the Standard if they are not exposed to any regulatory pressure or external demand. They are more concerned with quality and safety issues with the most adopted international standard among the industries being the ISO 9001 quality management system. This study highlights the aspect that financial barriers are not always the hurdles for implementing environmental management strategies in developing countries and underscores the need for regulatory frameworks and enforcement.

    Full Text Available The majority of workers have many occasional difficulties that sometimes become a problem affecting the worker’s performance. When this will repeatedly fail to meet expectations, a serious problem may become the main reason which contributes to the job decline. Therefore, a pattern of reduced performance indicates the need for a supervisory action from managers. Poor performance could be reflected under three main categories, such as employee availability, employee productivity, and employee conduct. The reasons and causes of this poor performance could be a personal issue related to the employee. Many types of personal problems are affecting the job performance in organizations, such as marital strife, financial difficulties and child care complication. More serious difficulties and the abuse of these problems-if not resolved-may cause unending issues at work. This problem is highly important especially that it can affect the job performance and the company income. Moreover, it can simply result in the failure of the employee to meet the performance standards, which kills productivity. The purpose of this qualitative exploratory phenomenological study is to clarify the management role in dealing with employees personal issues in the Lebanese organizations as perceived by the lived experience of managers. The research instrument which will be used is a face-to-face structured interview with six managers of the major functions in different Lebanese organizations. The sample type will be by convenience.

    The challenge posed by the nutrition transition occurring throughout the world is enormous: rates of chronic disease, particularly overweight and obesity and cardiovascular disease, have reached alarming levels-often occurring in parallel with high levels of micronutrient deficiencies. Lebanon is no exception. And yet this Mediterranean country enjoys a rich biodiversity, with thousands of endemic species and an equally rich culinary history, largely based on its local biodiversity, including wild edible plants. To record traditional Lebanese recipes based on wild edible plants and to investigate their potential to contribute to a more diversified diet. A series of nine focus group meetings was conducted with key informants knowledgeable in wild edible plant identification, harvesting, and use. Common recipes based on wild edible plants were collected and standardized from rural communities where collection of wild edible plants is common. Nutrient analysis and food-composition analysis were performed, including comparisons with processed dishes that are increasingly common in the Lebanese diet, revealing that the wild edible plant-based dishes offered a healthier alternative. Since traditional recipes often use items from several food groups in one dish, they can be a good model for diet diversification. The promotion of the collection and use of wild edible plants and their derived products can lead to improved nutrition.

  20. La publicité des artisans en France au XXème siècle

    OpenAIRE

    2008-01-01

    Les artisans sont généralement considérés comme des entrepreneurs qui ne font pas de publicité. La façon dont s'est organisée la profession publicitaire au début du XXème siècle tend à les reléguer hors de ce champ. Pourtant, il existe bien une communication commerciale des artisans. Pour exister dans leur espace, ceux-ci communiquent par des moyens qui se diversifient au cours du XXème siècle (enseignes, documents commerciaux, encarts...). Cette communication a ses thématiques propres. Avec ...

    Full Text Available The relationship between environmental exposure and health outcomes is complex, multidirectional and dynamic. Therefore, we need an understanding of these linkages for effective health risk communication. Despite the severe health hazards, artisanal gold mining is widespread globally, with an estimated 30 million people engaged in it. In this study, the relationships between artisanal gold miners’ knowledge of environmental and health effects of Hg and compositional, contextual and occupational factors were assessed using generalized linear models (negative log-log regression. A cross-sectional survey in three urban gold mining hubs in Ghana (Prestea, Tarkwa and Damang, was carried out among 588 (482 male and 106 female artisanal gold miners. The results showed that 89% of artisanal gold miners had very low to low levels of knowledge whereas 11% had moderate to very high levels of knowledge of deleterious health effects of Hg. Also, individuals who perceived their health-related work conditions to be excellent had very low to low levels of knowledge of environmental and health effects of Hg. Interestingly, artisanal gold miners who were still working were less likely to know the environmental and health effects of Hg compared with their counterparts who were currently unemployed. Similarly, artisanal gold miners who had attained either primary or secondary education were less likely to know the environmental and health effects of Hg compared with their counterparts who had no formal education. This finding, although counterintuitive, can be understood within the fact that artisanal gold miners in Ghana without formal education tend to have considerably higher number of years of practical experience compared with their counterparts with formal education. Female artisanal gold miners were 68% less likely to know the environmental and health effects of Hg compared with their male counterparts (OR=0.32, p<0.05. Artisanal gold miners who had

    Present study will treat the next topics: ecology of the natural and man made environments and functional diversity of bacteria. The microbial communities in artisanal goat cheeses produced in mountain pastures (typical farms) in Piemonte mountain (North of Italy) change a lot during precessing and ripening time. Moreover cheese microbial ecosystems are different in each small dairy because adventitious microflora can come from the environment and contamination the milk before the cheese making process and the product during manufacture and ripening.

    2014-10-01

    Full Text Available Based on a review of published and unpublished reports we analyzed Rapa Nui's (Easter Island traditional and artisan fisheries. We include information from 2000-2009 on landings, species, fishing grounds, fleet and number of fisherfolks according to the Servicio Nacional de Pesca (SERNAPESCA and personal communication with SERNAPESCA officials. Presently, 29 species of fishes and two invertebrates are fished (along with a group of species reported as "non-identified", primarily from the 10 main fishing grounds within 5 nm from the shore. Sporadic fishing trips reach areas up to 25 nm offshore. Statistics about the artisan fleet and number of operative fishers is spotty and unreliable. In 2011 SERNAPESCA reported 123 artisan fishers and 31 boats for the island. Landings occur in five coves, of which Hanga Piko and Hanga Roa are the most important. Between 2000-2009 the mean annual landing ranged between 109-171 ton. The main exploited resources during this period were yellowfin tuna, snoek, Pacific rudderfin, rainbow runner, glasseye, oilfish, deep-water jack and swordfish. We highlight the urgent need to improve fisheries statistics (catch, effort, fishing grounds in order to develop a science-fishery management and conservation plan, particularly linked with artisan fishery activities. Globally, we identify the need to integrate across fields (i.e., ecology, conservation, fisheries, education, outreach more broadly in the national research system, to improve the management and conservation of Easter Island's unique marine environment. Within this framework, we identify an urgent need to create a research marine station on the island with permanent personnel, which can focus on this fragile oligotrophic ecosystem.

  6. Assessing environmental impacts using a comparative LCA of industrial and artisanal production processes: "Minas Cheese" case

    2014-09-01

    Full Text Available This study uses the Life Cycle Assessment (LCA methodology to evaluate and compare the environmental impacts caused by both the artisanal and the industrial manufacturing processes of "Minas cheese". This is a traditional cheese produced in the state of Minas Gerais (Brazil, and it is considered a "cultural patrimony" in the country. The high participation of artisanal producers in the market justifies this research, and this analysis can help the identification of opportunities to improve the environmental performance of several stages of the production system. The environmental impacts caused were also assessed and compared. The functional unit adopted was 1 kilogram (Kg of cheese. The system boundaries considered were the production process, conservation of product (before sale, and transport to consumer market. The milk production process was considered similar in both cases, and therefore it was not included in the assessment. The data were collected through interviews with the producers, observation, and a literature review; they were ordered and processed using the SimaPro 7 LCA software. According to the impact categories analyzed, the artisanal production exerted lower environmental impacts. This can be justified mainly because the industrial process includes the pasteurization stage, which uses dry wood as an energy source and refrigeration.

    Full Text Available Purpose: To evaluate the efficacy, safety, predictability and stability of implanting a polymethylmethacrylate phakic intraocular lens (PIOL in high myopia. Materials and Methods: A retrospective analysis of the data of patients who underwent Artisan phakic IOL implantation between 2002 and 2003 with a follow-up of at least 24 months. Results: An Artisan myopia lens was implanted in 60 eyes of 36 patients with preoperative myopia ranging from -5.0 to -24.0 D. Mean patient age was 22.6 years. Mean spherical equivalent of manifest refraction stabilized by the first postoperative week. At three months follow-up, 54 eyes (90% had a postoperative refraction within ± 1D emmetropia and 45 eyes (75% had uncorrected visual acuity of 20/40 or better. Seven eyes (11.6% had loss of one Snellen line and none had loss of two Snellen lines or more at three months. The mean endothelial cell loss was 3.8% at three months, 5.2% at six months, 5.25% at 12 months and 6.38% at two years, which was not significant. Postoperative complications included anterior chamber reaction in two eyes (3.3%, rise in intraocular pressure in six eyes (10% and dislocation of PIOL in two eyes (3.3%. Conclusion: Implantation of Artisan myopia lens to correct high myopia resulted in a stable and fairly predictable refractive outcome with few complications. Significant endothelial damage was not detected in two years of follow-up.

  8. The artisanal elasmobranch fishery of the Pacific coast of Baja California Sur, Mexico, management implications

    Directory of Open Access Journals (Sweden)

    Sergio R. Ramirez-Amaro

    2013-09-01

    Full Text Available Artisanal fisheries in Mexico account for approximately 40% of the total national catch. In 2009, Baja California Sur (BCS had the second largest catch of elasmobranchs on the Mexican Pacific coast. This paper characterizes and describes the artisanal elasmobranch fishery of Pacific coast of BCS from 2000 to 2010. Sixty artisanal camps were documented, of which 45 targeted elasmobranchs, using primarily gillnets and longlines. We identified 52 elasmobranch species. Gillnetting accounted for 73.5% of the fishing effort and most frequently captured Rhinobatos productus, Mustelus henlei and Myliobatis californica. Longline fishing accounted for 26.5% of effort, most frequently capturing Prionace glauca and Isurus oxyrinchus. The prevalence of juveniles of several species (e.g., Cephaloscyllium ventriosum, Galeorhinus galeus, Isurus oxyrinchus, and Myliobatis californica within landings suggests that fishing effort may be opportunistically directed at breeding or nursery areas. Despite the dominance of species with wide distributions, we observed a significant biogeographic pattern in the abundance of some species relative to Bahia Magdalena. Results of the present study will be useful to detect changes in the structure of commercially exploited elasmobranch populations, and to provide useful indications for management purposes.

    Full Text Available Problem statement: The possible exposure of heavy elements to life as a result of artisanal gold mining activities can be of great concern because of its associated effect on health. Approach: Soil samples from the artisanal gold mining sites of Awwal and Bagega villages in Kebbi and Zamfara states of Nigeria were collected and analyzed for heavy and other elements by X-Ray Fluorescence (XRF technique. Ten of the element analyses are presented in this study, based on their toxicity levels. Results: Four of the ten elements (Pb, Si, Rb and Fe showed relatively high concentrations. Two of these four elements presented, (Si and Pb may pose latent and immediate hazards to health. Respiratory crystalline silica is the major element constituent of the ever-well-pronounced mining dusts of the two sites. Its form of occurrence portends irreversible health problem called silicosis and is well linked to cancer forming properties; both of which develop through latency periods. Pb at whatever concentration portends both immediate and long term hazards to women and children at the greatest risks of exposures. Conclusion: Based on the results presented, there exist a possibility of an immediate and long term health risks associated with the artisanal gold mining exercises in the two sites studied if the said uncoordinated and unprofessional activities of the miners are left unchecked.

    The artisanal fisheries of Ecuador operate within one of the most dynamic and productive marine ecosystems of the world. This study investigates the catch composition of the Ecuadorian artisanal fishery for large pelagic fishes, including aspects of its spatio-temporal dynamics. The analyses of this study are based on the most extensive dataset available to date for this fishery: a total of 106,963 trip-landing inspection records collected at its five principal ports during 2008 ‒ 2012. Ecuadorian artisanal fisheries remove a substantial amount of biomass from the upper trophic-level predatory fish community of the eastern tropical Pacific Ocean. It is estimated that at least 135 thousand metric tons (mt) (about 15.5 million fish) were landed in the five principal ports during the study period. The great novelty of Ecuadorian artisanal fisheries is the “oceanic-artisanal” fleet component, which consists of mother-ship (nodriza) boats with their towed fiber-glass skiffs (fibras) operating with pelagic longlines. This fleet has fully expanded into oceanic waters as far offshore as 100°W, west of the Galapagos Archipelago. It is estimated that nodriza operations produce as much as 80% of the total catches of the artisanal fishery. The remainder is produced by independent fibras operating in inshore waters with pelagic longlines and/or surface gillnets. A multivariate regression tree analysis was used to investigate spatio-environmental effects on the nodriza fleet (n = 6,821 trips). The catch species composition of the nodriza fleet is strongly influenced by the northwesterly circulation of the Humboldt Current along the coast of Peru and its associated cold waters masses. The target species and longline gear-type used by nodrizas change seasonally with the incursion of cool waters (< 25°C) from the south and offshore. During this season, dolphinfish (Coryphaena hippurus) dominates the catches. However, in warmer waters, the fishery changes to tuna

    The aims of this work were to characterize the fermentation process of mezcal from San Luis Potosi, México and identify the yeasts present in the fermentation using molecular culture-dependent methods (RFLP of the 5.8S-ITS and sequencing of the D1/D2 domain) and also by using a culture-independent method (DGGE). The alcoholic fermentations of two separate musts obtained from Agave salmiana were analyzed. Sugar, ethanol and major volatile compounds concentrations were higher in the first fermentation, which shows the importance of having a quality standard for raw materials, particularly in the concentration of fructans, in order to produce fermented Agave salmiana must with similar characteristics. One hundred ninety-two (192) different yeast colonies were identified, from those present on WL agar plates, by RFLP analysis of the ITS1-5.8S- ITS2 from the rRNA gene, with restriction endonucleases, HhaI, HaeIII and HinfI. The identified yeasts were: Saccharomyces cerevisiae, Kluyveromyces marxianus, Pichia kluyveri, Zygosaccharomyces bailii, Clavispora lusitaniae, Torulaspora delbrueckii, Candida ethanolica and Saccharomyces exiguus. These identifications were confirmed by sequencing the D1-D2 region of the 26S rRNA gene. With the PCR-DGGE method, bands corresponding to S. cerevisiae, K. marxianus and T. delbrueckii were clearly detected, confirming the results obtained with classic techniques.

    Proper nutrition is critical for healthy aging and maintaining functional independence. Limited research has been done on the assessment of dietary patterns of older adults and their association with diet quality indices. This study was conducted to identify, characterize, and evaluate the dietary patterns and diet quality of older adults in Lebanon, a middle-income country undergoing nutrition transition. A cross-sectional population-based study was conducted on a nationally representative sample of community-dwelling older adults aged >50 years (n = 525). Socio-demographic, anthropometric, and lifestyle variables were collected through interviews, and dietary intake was assessed using a semi-quantitative food frequency questionnaire (FFQ). Five commonly used diet quality indices (DQIs) were calculated, including the Alternative Healthy Eating Index (AHEI), the alternate Mediterranean diet score (aMed), the Dietary Approach to Stop Hypertension (DASH) style diet score, and the Lebanese Mediterranean Diet index. Dietary patterns (DPs) were derived using exploratory factor analysis. Associations of identified DPs with energy, energy-adjusted nutrients, and DQIs were evaluated by Pearson's correlations. Multiple linear regression analyses were used to examine correlates of DPs. Three DPs were derived: Lebanese, Western, and High Protein/Alcohol patterns. The Lebanese pattern had highest correlations with fiber, folate, vitamin C, and all five DQIs. The Western was positively associated with energy and sodium and was inversely correlated with fiber, most vitamins, and a number of DQIs, namely AHEI, aMED, and DASH-style diet score. Highest correlations with intakes of proteins and fat were observed for the High Protein/Alcohol pattern. The Lebanese pattern was associated with female gender, education, nonsmoking and physical activity, whereas the Western pattern was associated with adverse health behaviors, including smoking, skipping breakfast, and physical inactivity

    In Lebanon, neglect of the electricity sector has led to a serious shortage in installed capacity. Recently, the government of Lebanon declared its intention to raise the share of renewable energy (RE) year by year in order to reduce energy consumption. This paper gave a cost-benefit analysis and reviewed the replacement of five major traditional household appliances with their energy efficient (EE) or renewable energy counterparts. This initiative would mostly be felt in three main areas: electricity consumption, consumer costs, and government expenditure. There is a strong possibility that the electricity demand of the 1.2 million Lebanese households can be reduced by introduction of these EE household appliances. Benefits would also accrue to the government in the form of avoided subsidies and reduced need for installed capacity. This paper finds that the benefits to be expected from these policy recommendations largely outweigh the costs.

    Nosocomial infections are a significant problem and hospitals need to be aware of their nosocomial infection status. This retrospective study aimed to identify nosocomial bacterial infections in patients admitted to the Lebanese Hospital Center from January 2006 to January 2008 and determine the causative micro-organisms, the antibiotic sensitivity of the micro-organisms and evaluate the hospital treatment. In total 96 patients with nosocomial infection were included. Urinary infections were the commonest nosocomial infections (42%) followed by pulmonary infections (28%). Gram-negative bacteria were responsible for 89% of nosocomial infections and staphylococci for 7%, with Escherichia coli and Pseudomonas aeruginosa being the most common (46% and 26% respectively). The organisms were resistant to multiples antibiotics and 18% of the patients were treated with imipenem, 7% with vancomycin, 42% with third-generation cephalosporins and 24% with amikacin. Hospital hygiene measures and antibiotic prescription policies are required to fight nosocomial infections and reduce antibiotic resistance among organisms.

    Artisan fresh Mexican-style cheeses are commonly made from raw milk that provides not only rich flavors, but also a diversity of associated lactic acid bacteria (LAB) strains. Enterococcus faecium UQ31 was isolated from panela cheese and produced bacteriocin-like inhibitory substances (BLIS) with a strong anti-Listeria activity. A modified pH-mediated adsorption-desorption purification process resulted in (after SDS-PAGE) two bands showing antimicrobial activities, where most of the activity corresponded to the band with an estimated molecular weight of 7.5 kDa. The BLIS produced by E. faecium UQ31 were heat resistant, stable at ambient storage conditions, and active in the pH range 5--9. The BLIS antimicrobial activities were detected during logarithmic growth phase and remained constant until the end of incubation time (19 h). These BLIS showed a wide anti-Listeria monocytogenes spectra. The E. faecium UQ31 strain or their BLIS represent a promising potential as antimicrobial food preservatives.

    Plasminogen activator inhibitor-1 (PAI-1) is an inhibitor of fibrinolysis. Increased plasma PAI-1 levels play an essential role in the pathogenesis of cardiovascular risk and other diseases associated with thrombosis. The 4G/5G polymorphism of the PAI-1 promoter region has been extensively studied in different populations. We studied 160 healthy unrelated Lebanese individuals using a reverse hybridization PCR assay to detect the 5G/5G, 4G/5G and, 4G/4G genotypes of the PAI-1 gene and the frequencies of the 4G and 5G alleles. We found that 4G/5G genotype was the most prevalent (45.6%) followed by 5G/5G (36.9%) and 4G/4G (17.5%). The frequencies of the 4G and 5G alleles were calculated to be 0.403 and 0.597, respectively. Compared to other ethnic communities, the Lebanese population was found to harbour a relatively high prevalence of the rare 4G allele. This, in turn, may predispose this population to develop cardiovascular diseases and other thrombotic clinical conditions. This study aids to enhance our understanding of the genetic features of the Lebanese population.

    Neuropsychological tests (NPTs) are highly dependent on education, culture differences as well as age and sex. It is therefore essential to take these factors into consideration when translating NPTs to be used in screening for cognitive impairment. Translations into Arabic must respect the principles of linguistic relativity and cultural specificity of the population under study. The objective is to assess feasibility and outcome of translating neuropsychological tests to Arabic. A team of Lebanese professionals selected a battery of screening NPTs. These tests were translated into Arabic and independently back translated by a team of sociolinguists and cultural specialists. The translations were adapted to suit the Lebanese culture. The final NPT translated versions were reached by consensus of an expert panel and tested on a group of independently living community-dwelling elderly. Translated items had to be modified when: (1) terms could not be translated using one word as required by the test; (2) Concepts were foreign to the culture; (3) Translated words carried multiple meanings; (4) Words were rarely used in Lebanon; (5) Sentences did not have an equivalent; and (6) Words had letters pronounced differently by subgroups in Lebanon. Despite all measures to maintain cultural sensitivity in translations, non-linguistic challenges remained. A battery of cognitive screening tests were translated into Arabic and adapted for the Lebanese population. These adaptations allow for a better assessment of cognitive abilities since they reflect the thought patterns of the population. The challenge is to establish local normative data.

    The aims of our study were to establish reference values for insulin-like growth factor 1 (IGF-1) in Lebanese schoolchildren and to evaluate the relationship between IGF-1 and age, sex, body mass index (BMI), vitamin D, and ferritin. This cross-sectional study included 952 Lebanese schoolchildren (495 boys and 457 girls) aged 8 to 18 years. Blood samples were taken from children attending 10 schools with different socio-economic status (SES). Chemiluminescent immunoassays were used for IGF-1, 25 hydroxyvitamin D (25(OH)D), testosterone, and ferritin measurements. The mean age was 13.46 ± 2.80 with no significant difference according to sex. IGF-1 was correlated with age in both sexes (Pferritin values. After adjustment for age, BMI, and height, the correlation between IGF-1 and 25(OH)D disappeared, whereas the relationship with ferritin persisted (Pferritin. An association was also noted in boys for BMI and testosterone. Our results showed higher and earlier peak IGF-1 values in the pediatric Lebanese population compared to western populations. In addition, an independent inverse relationship was observed between IGF-1 and ferritin. Further studies are needed to identify the reason(s) underlying these results. BMI = body mass index CRP = C-reactive protein CV = coefficient of variation GH = growth hormone IGF-1 = insulin-like growth factor 1 25(OH)D = 25 hydroxyvitamin D SES = socio-economic status TSH = thyroid-stimulating hormone.

    Objective: The aim of this study was to describe the diameter and the position of the greater palatine foramen (GPF) in relation to adjacent anatomical landmarks in the maxilla in a Lebanese population using cone-beam computed tomography (CBCT) technology. Materials and Methods: CBCT images of 58 Lebanese adult patients were included in this study and a total of 116 GPF were evaluated bilaterally. The diameter of the GPF and its position relative to the maxillary molars, and distances to the midline maxillary suture and to the anterior nasal spine were analyzed. Results: Of all foramina assessed, 41.38% were located opposite to the third molar, 29.31% were distal to it, 27.59% were between the second and the third, and only 1.72% were opposite to the second. The average diameter was 5.633 mm on the right and 5.723 mm on the left, and the average distances to midline maxillary suture and anterior nasal spine were 16.228 mm and 48.294 mm on the right and 14.907 mm and 48.122 mm on the left, respectively. Conclusion: Within the limits of this study, we conclude that in Lebanese patients, the GPF location is variable, very rarely opposite to the second molar, and more closely related to the third, but may present mesial or distal to it in one-fourth of patients.

    Ice cream, a popular product worldwide, is usually a milk-based product with other types of ingredients (fruit, eggs, cocoa, dried fruit, additives, and others). Different materials are used to obtain the desired taste, texture, consistency, and appearance of the final product. This study surveyed ice cream products available in Italy for heavy metals (lead, cadmium, chromium, tin, and arsenic). The differences between artisanal and industrial ice cream were also investigated because of the importance in the Italian diet and the diffusion of this ready-to-eat food. Ice cream sampling was performed between October 2010 and February 2011 in the northeast of Italy. A total of 100 samples were randomly collected from different sources: 50 industrial samples produced by 19 different brands were collected in coffee bars and supermarkets; 50 artisanal ice cream samples were gathered at nine different artisanal ice cream shops. Ten wooden sticks of industrial ice cream were analyzed in parallel to the ice cream. All samples were negative for arsenic and mercury. None of the artisanal ice cream samples were positive for lead and tin; 18% of the industrial ice cream samples were positive. All positive lead samples were higher than the legal limit stated for milk (0.02 mg/kg). All industrial ice cream samples were negative for cadmium, but cadmium was present in 10% of the artisanal ice cream samples. Chromium was found in 26% of the artisanal and in 58% of the industrial ice cream samples. The heavy metals found in the wooden sticks were different from the corresponding ice cream, pointing out the lack of cross-contamination between the products. Considering the results and the amount of ice cream consumed during the year, contamination through ice cream is a low risk for the Italian population, even though there is need for further analysis.

    Environmental geochemistry classifies elements into essential, non-essential and toxic elements in relationship to human health. To assess the environmental impact of mining at Datoko-Shega area, the distributions and concentrations of trace elements in stream sediments and soil samples were carried out. X-ray fluorescence analytical technique was used to measure the major and trace element concentrations in sediments and modified fire assay absorption spectrometry in soils. The results showed general depletion of major elements except titanium oxide (TiO2) compared to the average crustal concentrations. The retention of TiO2 at the near surface environment probably was due to the intense tropical weathering accompanied by the removal of fine sediments and soil fractions during the harmattan season by the dry north-east trade winds and sheet wash deposits formed after flash floods. The results also showed extreme contamination of selenium (Se), cadmium (Cd) and mercury (Hg), plus strong contaminations of arsenic (As) and chromium (Cr) in addition to moderate contamination of lead (Pb) in the trace element samples relative to crustal averages in the upper continental crust. However Hg, Pb and Cd concentrations tend to be high around the artisanal workings. It was recognised from the analysis of the results that the artisanal mining activity harnessed and introduces some potentially toxic elements such as Hg, Cd and Pb mostly in the artisan mine sites. But the interpretation of the trace element data thus invalidates the elevation of As concentrations to be from the mine operations. It consequently noticed As values in the mine-impacted areas to be similar or sometimes lower than As values in areas outside the mine sites from the stream sediment results.

  5. Optimum Fisheries Management under Climate Variability: Evidence from Artisanal Marine Fishing in Ghana

    2015-06-01

    Full Text Available In most developing coastal countries, the artisanal fisheries sector is managed as a common pool resource. As a result, such fisheries are overcapitalized and overfished. In Ghana, in addition to anthropogenic factors, there is evidence of rising coastal temperature and its variance, which could impact the environmental carrying capacity of the fish stock. This study investigates the effect of climate variation on biophysical parameters and yields. Our results indicate that the rising temperature is decreasing the carrying capacity. As a result, an optimum tax on harvest must reflect climate variability, as well as the congestion externality.

    The artisanal gold mining sector in Colombia has 200,000 miners officially producing 30tonnes Au/a. In the Northeast of the Department of Antioquia, there are 17 mining towns and between 15,000 and 30,000 artisanal gold miners. Guerrillas and paramilitary activities in the rural areas of Antioquia pushed miners to bring their gold ores to the towns to be processed in Processing Centers or entables. These Centers operate in the urban areas amalgamating the whole ore, i.e. without previous concentration, and later burn gold amalgam without any filtering/condensing system. Based on mercury mass balance in 15 entables, 50% of the mercury added to small ball mills (cocos) is lost: 46% with tailings and 4% when amalgam is burned. In just 5 cities of Antioquia, with a total of 150,000 inhabitants: Segovia, Remedios, Zaragoza, El Bagre, and Nechí, there are 323 entables producing 10-20tonnes Au/a. Considering the average levels of mercury consumption estimated by mass balance and interviews of entables owners, the mercury consumed (and lost) in these 5 municipalities must be around 93tonnes/a. Urban air mercury levels range from 300ng Hg/m(3) (background) to 1million ng Hg/m(3) (inside gold shops) with 10,000ng Hg/m(3) being common in residential areas. The WHO limit for public exposure is 1000ng/m(3). The total mercury release/emissions to the Colombian environment can be as high as 150tonnes/a giving this country the shameful first position as the world's largest mercury polluter per capita from artisanal gold mining. One necessary government intervention is to cut the supply of mercury to the entables. In 2009, eleven companies in Colombia legally imported 130tonnes of metallic mercury, much of it flowing to artisanal gold mines. Entables must be removed from urban centers and technical assistance is badly needed to improve their technology and reduce emissions. Copyright © 2011 Elsevier B.V. All rights reserved.

    Artisanal and small-scale gold mining (ASGM) is growing in many regions of the world including Ghana. The problems in these communities are complex and multi-faceted. To help increase understanding of such problems, and to enable consensus-building and effective translation of scientific findings to stakeholders, help inform policies, and ultimately improve decision making, we utilized an Integrated Assessment approach to study artisanal and small-scale gold mining activities in Ghana. Though Integrated Assessments have been used in the fields of environmental science and sustainable development, their use in addressing specific matter in public health, and in particular, environmental and occupational health is quite limited despite their many benefits. The aim of the current paper was to describe specific activities undertaken and how they were organized, and the outputs and outcomes of our activity. In brief, three disciplinary workgroups (Natural Sciences, Human Health, Social Sciences and Economics) were formed, with 26 researchers from a range of Ghanaian institutions plus international experts. The workgroups conducted activities in order to address the following question: What are the causes, consequences and correctives of small-scale gold mining in Ghana? More specifically: What alternatives are available in resource-limited settings in Ghana that allow for gold-mining to occur in a manner that maintains ecological health and human health without hindering near- and long-term economic prosperity? Several response options were identified and evaluated, and are currently being disseminated to various stakeholders within Ghana and internationally. PMID:26393627

    2015-03-01

    Full Text Available Physical, physicochemical, and microbiological changes were monitored in 256 samples of artisanal Minas cheese from eight producers from Serro region (Minas Gerais, Brazil for 64 days of ripening to determine the minimum ripening time for the cheese to reach the safe microbiological limits established by Brazilian legislation. The cheeses were produced between dry season (April–September and rainy season (October–March; 128 cheeses were ripened at room temperature (25 ± 4 °C, and 128 were ripened under refrigeration (8 ± 1 °C, as a control. No Listeria monocytogenes was found, but one cheese under refrigeration had Salmonella at first 15 days of ripening. However, after 22 days, the pathogen was not detected. Seventeen days was the minimum ripening time at room temperature to reduce at safe limits of total coliforms > 1000 cfu.g−1, Escherichia coli and Staphylococcus aureus (> 100 cfu.g−1 in both periods of manufacture. Otherwise under refrigeration, as expected, the minimum ripening time was longer, 33 days in the dry season and 63 days in the rainy season. To sum up, we suggest that the ripening of artisanal Minas cheese be done at room temperature, since this condition shortens the time needed to reach the microbiological quality that falls within the safety parameters required by Brazilian law, and at the same time maintain the appearance and flavor characteristics of this traditional cheese.

  13. The Legal Regulation of Artisan and Trade Corporations in the Cities of Medieval Europe

    Valentine G. Medvedev

    2015-06-01

    Full Text Available This article features an analysis of the legal regulation of the formation and activity of artisan and trade corporations in the cities of medieval Europe. Based on the findings of an analysis of existing scientific theories, as well as a study of legal and regulatory acts, the author aims to explore the issue of the emergence of cities and workshop organizations in them and reveal their legal essence and content. The relevance of this paper is due to the fact that up until now a sufficiently definitive opinion is yet to be propounded in historical and historical/legal science as to the origin and development of such specific urban institutions as workshops and workshop corporations, with their special legal regulation. The author comes to the conclusion that the formation of cities and workshop organizations reflected the evolution of the economic and social development of medieval society, which was associated with social division of labor. The paper’s major focus is not on the statutory regulation of the work of masters and not on the regulation of workshop craft methods, which can be explained quite logically by the economic need for adapting medieval artisan production to the limited needs and capacity of the local market, and which is the subject of study for the majority of present-day scholars, but issues related to the very organization of the workshop, its position in the system of urban establishments, as well as the legal status of its members.

    The sampling of fish from the artisanal fleet operating with surface lines off north-eastern Brazil was carried out between 1998 and 2000. Generalized linear models (GLMs) were used to standardize mean abundance indices using catch and fishing effort data on dolphinfish Coryphaena hippurus and to identify abundance trends in time and space, using 1215 surface line deployments. A standard relative abundance index (catch per unit effort, CPUE) was estimated for the most frequent vessels used in the sets, employing factors and coefficients generated in the GLMs. According to the models, C. hippurus catches are affected by the operating characteristics and power of different fishing vessels. These differences highlight the need for standardization of catch and effort data for artisanal fisheries. The highest mean abundance values for C. hippurus were off the state of Rio Grande do Norte, with an increasing tendency in areas with greater depths and more distant from the coast, reaching maximal values in areas whose depths range from 200 to 500 m. The highest mean abundance values occurred between April and June. The higher estimated abundance of C. hippurus in this period off the state of Rio Grande do Norte and within the 200-500 m depth range may be related to a migration pattern of food sources, as its main prey, the flying fish Hirundichthys affinis, uses floating algae as refuge and to deposit its pelagic eggs.

    Full Text Available This study investigated the profitability of artisanal fishing in river Asa in Asa Local Government Area of Kwara State, Nigeria. A total of 80 respondents were randomly selected for the study. Data were collected by the use of structured set of questionnaires. Three research questions guided the study. Results of profitability analysis showed that an average fisherman makes a Gross Margin of ₦52883.99/fisherman/month. The problems of artisanal fishing included lack of storages facilities, lack of government support and seasonal change in the volume of the river. The study recommends among others; fishermen should be given adequate training and the required assistance on modern fishing techniques and use of modern fishing equipment to ensure sustainability. There is also the need to organise the farmers into cooperatives to enable them have better access to government programmes and credits. It is also recommended that the government should build mini cold rooms with good storage facilities to help the fishermen overcome the problem of fish spoilage which reduces the quality of their products.

    Soil contamination with heavy metals due to mining activities poses risks to ecological safety and human well-being. Limited studies have investigated heavy metal pollution due to artisanal mining. The present study focused on soil contamination and the health risk in villages in China with historical artisanal mining activities. Heavy metal levels in soils, tailings, cereal and vegetable crops were analyzed and health risk assessed. Additionally, a botany investigation was conducted to identify potential plants for further phytoremediation. The results showed that soils were highly contaminated by residual tailings and previous mining activities. Hg and Cd were the main pollutants in soils. The Hg and Pb concentrations in grains and some vegetables exceeded tolerance limits. Moreover, heavy metal contents in wheat grains were higher than those in maize grains, and leafy vegetables had high concentrations of metals. Ingestion of local grain-based food was the main sources of Hg, Cd, and Pb intake. Local residents had high chronic risks due to the intake of Hg and Pb, while their carcinogenic risk associated with Cd through inhalation was low. Three plants (Erigeron canadensis L., Digitaria ciliaris (Retz.) Koel., and Solanum nigrum L.) were identified as suitable species for phytoremediation. Copyright © 2017. Published by Elsevier Inc.

    Full Text Available This paper introduces a socio-ecological analysis of the artisanal fisheries system on Easter Island (27°07'S, 109°22'W through the identification and interaction of stakeholders. It also comprises a structural analysis of the system aiming to identify any key issues and then propose research and development programs for multiple fisheries that will contribute to their sustainable development. The methodology is divided into four stages: i identification of issues with stakeholder (fishers, government workers and expert scientists participation, ii analysis of a structural matrix consisting of a direct causality study of the symmetric, structural and binary matrix based on socio-ecological issues allowing the calculation of the level of influence and dependence of each issue, iii identification of key issues with an influence/dependency diagram, and iv proposal of research and development programs according to the needs and opportunities identified in the previous stages. The Easter Island artisanal fishing system is used as a case study for this methodological approach. Thus, the fishers identified 108 issues, which were then grouped by similarity, reducing the number to 27 global issues, of which seven were identified as key. Surveyed local and central government workers and expert scientists identified 7, 2 and 5 issues, respectively. Finally, research and development programs are proposed that will encourage a series of changes to the fisheries situation on the island, in order to resolve issues and promote their sustainable development.

  18. Injuries among Artisanal and Small-Scale Gold Miners in Ghana

    2015-09-01

    Full Text Available Artisanal and small-scale gold miners are confronted with numerous hazards often resulting in varying degrees of injuries and fatalities. In Ghana, like many developing countries, there is paucity of information on the causes and nature of the accidents that result in the injuries. The study was a retrospective, cross sectional type that examined the records of injuries of artisanal and small-scale gold miners presented to the emergency department of a district hospital in the Eastern Region of Ghana from 2006 to 2013. The causes, types, and outcomes of reported injuries were analyzed for 72 cases. Occurrences of mining accidents reported in selected Ghanaian media during the year 2007–2012 were also analyzed to corroborate the causes of the accidents. Fractures and contusions constituted the most frequently occurring injuries, with collapse of the mine pits and falls being the most frequent cause of accidents reported both by the hospital and media records. This study shows that though varied degrees of injuries occur among the miners, the potential for serious injuries is substantial. Measures to reduce the incidence of injuries and fatalities should include education and training on the use of safe working tools and means of creating a safe working environment.

    Artisans in Masisi and other parts of the North Kivu province in the eastern Democratic Republic of Congo (DRC) mine columbite-tantalite mineral ores (also called 'coltan') for the tantalum content. The potential occupational radiation exposures in the course of this operation, due to the presence of naturally occurring radioactive material (NORM), have been investigated in this screening survey. Activity concentrations of the naturally occurring radionuclides in samples of coltan were measured using gamma-ray spectrometry. The average values in Bq g(-1) are 10.75 +/- 5.11 for (238)U, 7.06 +/- 3.39 for (226)Ra, 1.75 +/- 0.85 for (232)Th, and 1.63 +/- 0.52 for (40)K. Based on these values and the working scenarios involved in artisanal coltan mining, the occupational doses that may accrue from a variety of exposure pathways were determined by model calculations. The results, assuming conservative dust load and dilution factors, indicate that grinding and sieving coltan can give rise to high occupational doses, up to 18 mSv per annum on average.

    Mercury exposure has been described among small-scale gold mining communities in developing countries, but reports of inhalational mercury toxicity among home gold extractors in the US remain uncommon. We sought to identify inhalational mercury exposures and toxicity among artisanal gold extractors. This is an observational case series of a single Poison Center database from 2002-2015. We review all cases of "mercury" or "mercury inhalation" exposures, with detailed description of a recent representative case. Nine cases were reported, with patients' ages ranging 32-81 years. Eight (89%) patients were male. Seven of eight (88%) patients with acute exposures reported pulmonary symptoms consistent with mercury vapor inhalation such as dyspnea and cough; two (29%) patients had severe toxicity requiring intubation. Four of six (67%) patients had markedly elevated whole blood mercury concentrations up to 346 mcg/L; each received a different chelation regimen. Four (44%) patients used methamphetamines at the time of their exposure. The case report describes a patient with elevated mercury concentrations who required intubation for hypoxic respiratory failure. He received chelation therapy based on chelator availability, with decreasing 24-hour urine mercury concentrations. The house where he was exposed remains uninhabitable from elevated ambient mercury vapor concentrations. Artisanal gold extraction may be associated with inhalational mercury toxicity, including elevated blood mercury concentrations and acute hypoxic lung injury requiring intubation.

    Current solutions continue to be inadequate in addressing the longstanding, worldwide problem of mercury emissions from small artisanal gold mining. Mercury, an inexpensive and easily accessible heavy metal, is used in the process of extracting gold from ore. Mercury emissions disperse, affecting human populations by causing adverse health effects and environmental and social ramifications. Many developing nations have sizable gold ore deposits, making small artisanal gold mining a major source of employment in the world. Poverty drives vulnerable, rural populations into gold mining because of social and economic instabilities. Educational programs responding to this environmental hazard have been implemented in the past, but have had low positive results due to lack of governmental support and little economic incentive. Educational and enforced intervention programs must be developed in conjunction with governmental agencies in order to successfully eliminate this ongoing problem. Industry leaders offered hopeful suggestions, but revealed limitations when trying to develop encompassing solutions to halt mercury emissions. This research highlights potential options that have been attempted in the past and suggests alternative solutions to improve upon these methods. Some methods include buyer impact recognition, risk assessment proposals exposing a cost-benefit analysis and toxicokinetic modeling, public health awareness campaigns, and the education of miners, healthcare workers, and locals within hazardous areas of mercury exposure. These methods, paired with the implementation of alternative mining techniques, propose a substantial reduction of mercury emissions.

    The relationship between natural resources and armed conflict gained public and political attention in the 1990s, when it became evident that the mining and trading of diamonds were connected with brutal rebellions in several African nations. Easily extracted resources such as alluvial diamonds and gold have been and continue to be exploited by rebel groups to fund their activities. Artisanal and small-scale miners operating under a quasi-legal status often mine these mineral deposits. While many African countries have legalized artisanal mining and established flow chains through which production is intended to travel, informal trading networks frequently emerge in which miners seek to evade taxes and fees by selling to unauthorized buyers. These networks have the potential to become international in scope, with actors operating in multiple countries. The lack of government control over the artisanal mining sector and the prominence of informal trade networks can have severe social, political, and economic consequences. In the past, mineral extraction fuelled violent civil wars in Sierra Leone, Liberia, and Angola, and it continues to do so today in several other countries. The significant influence of the informal network that surrounds artisanal mining is therefore an important security concern that can extend across borders and have far-reaching impacts.

This study aimed to explore the impact of the national accreditation system in Lebanon on patient satisfaction. Methods An explanatory cross-sectional study of six hospitals in Lebanon. Patient satisfaction was measured using the SERVQUAL tool assessing five dimensions of quality (reliability, assurance, tangibility, empathy, and responsiveness. Independent variables included hospital accreditation scores, size, location (rural/urban, and patient demographics. Results The majority of patients (76.34% were unsatisfied with the quality of services. There was no statistically significant association between accreditation classification and patient satisfaction. However, the tangibility dimension – reflecting hospital structural aspects such as physical facility and equipment was found to be associated with patient satisfaction. Conclusion This study brings to light the importance of embracing more adequate patient satisfaction measures in the Lebanese hospital accreditation standards. Furthermore, the findings reinforce the importance of weighing the patient perspective in the development and implementation of accreditation systems. As accreditation is not the only driver of patient satisfaction, hospitals are encouraged to adopt complementary means of promoting patient satisfaction.

    Full Text Available Objective. To examine the prevalence and correlates of Complementary and Alternative Medicine (CAM use in Lebanon. Methods. A cross-sectional survey was conducted through face to face interviews on a nationally representative sample of 1,475 Lebanese adults. The survey questionnaire explored the sociodemographic and health related characteristics as well as the types and modes of CAM use. The main outcome in this study was the use of CAM during the last 12 months. Results. Prevalence of CAM use was 29.87% with “folk herbs” being the most commonly used (75%. Two out of five CAM users indicated using it as alternative to conventional therapies and only 28.4% of users disclosed the use of CAM to their physician. CAM use was significantly associated with higher income, presence of a chronic disease, and lack of access to needed health care. Lower odds of CAM use were observed among older adults and those with a higher education level. Conclusions. This study revealed a high prevalence of CAM use in Lebanon. Health policy and decision makers need to facilitate proper regulation and integration of CAM into mainstream medicine and educate health care providers and the public alike on the safe and effective use of CAM therapies.

    The study investigated three subjective wellbeing (SWB) components, namely positive affect (PA), negative affect (NA), and life satisfaction (LS), along with optimism and self-esteem and their association with academic achievement and multilinguality in a sample of 1401 Lebanese university students. As predicted, optimism and self-esteem correlated positively with LS and PA, and negatively with NA. Optimism, self-esteem and each of the SWB components jointly predicted academic achievement (GPA), with PA being an individually significant positive predictor. There were differences in the five key variables across language groups, specifically between Arabic-only speakers and some other groups: Compared Arabic-only speakers, bilingual speakers of Arabic and either English or French scored higher on self-esteem, PA and optimism, and lower on NA, while trilingual speakers of Arabic, English, and French scored higher on self-esteem, PA and LS. Language grouping was a significant predictor of the SWB components, optimism, and self-esteem even when controlling for GPA, socioeconomic status (SES), and religion. Lastly, the relevance of SES and religion for the prediction of SWB is discussed, and implications and future research questions are advanced.

    BACKGROUND In the present study, phytochemical screening, antioxidant, anti-inflammatory, and antiproliferative capacities of 3 extracts from leaves of Lebanese Crataegus azarolus L. were evaluated. MATERIAL AND METHODS Fresh leaves were dissolved in 3 different solvents: distilled water, ethanol, and methanol. The chemical composition was determined using high-performance liquid chromatography (HPLC) and the content of essential oil of this plant was examined by gas chromatography (GC) coupled with mass spectrometry (MS). The antioxidant potential was evaluated using DPPH radical scavenging and Fe2+ chelating activity assays. Anti-inflammatory effect was investigated by measuring the secreted amounts of the proinflammatory mediator PGE2 using ELISA technique, as well as by assaying the mRNA levels of the proinflammatory cytokines (IL-α, IL-β, and Il-6), chemokines (CCL3 and CCL4) and inflammation-sensitive COX2 and iNOS enzymes using quantitative real-time PCR (qRT-PCR). The antiproliferative effect was evaluated using the XTT viability assay. RESULTS The obtained results show that alcohol (methanol and ethanol) extracts were rich in bioactive molecules with medical relevance and exerted substantial antioxidant, anti-inflammatory, and antiproliferative capacities. On the other hand, aqueous extract contained fewer chemical components and exhibited less therapeutic efficiency. CONCLUSIONS Our observations indicate that Crataegus azarolus L. could be used for treating diseases related to oxidative stress, inflammatory reactions, and uncontrolled cell growth.

    The aim of this study is to assess the dissolved concentration of 45 pesticides in the surface waters of the Lebanese Republic using Polar Organic Chemical Integrative Sampler "POCIS". All of the sampling sites are located in the major agricultural land areas in Lebanon. POCIS (n = 3) were deployed at Ibrahim River, Qaraoun Lake and Hasbani River for a duration of 14 days. The total concentration of pesticides ranged from not detected (nd) to 137.66 ng.L-1. Chlorpyrifos, DDE-pp, diazinon and Fenpropathrin were the most abundant compounds. Qaraoun Lake and Hasbani River were found to be more polluted than Ibrahim River, since they receive large amounts of waste water derived from nearby agricultural lands and they had the lowest dilution factor. The aqueous average concentration of the target compounds were estimated using sampling rates obtained from the literature. Comparison between Time Weighed Average concentrations "TWA" using POCIS and spot sampling is presented. Results showed that POCIS TWA concentrations are in agreement with spot sampling concentrations for Ibrahim and Hasbani Rivers. The toxicity of the major detected pesticides on three representative aquatic species (Daphnia magna, Scenedesmus quadricauda and Oncorhynchus mykiss) is also reported.

Adult patients visiting the pharmacies with prescriptions of BDZs were included in the study. Seven hundred and eighty-six current BDZ users were included, of whom 54.2% were females. Twenty-three percent reported being alcohol consumers and were mostly males. The two most commonly used BDZs were alprazolam (34.6% and bromazepam (33.6%. The indication for use was mainly anxiety (44.4%, insomnia (22.5%, and depression (15.9%. The prescribing physicians were primarily psychiatrists (43.2%, followed by general practitioners (29.7%. Forty percent had been taking the drug for more than a year. Among those using BDZs for at least 1 month, 35.5% increased the dose with time. Thirty-three percent reported having experienced side effects. Eighteen patients (2.3% reported taking more than one BDZ concomitantly, while 18.3% were taking drugs that should not be prescribed along with BDZs. In conclusion, the use of BDZs is highest among females, especially for the treatment of anxiety. Moreover, continuous use of the drugs for more than a year as well as significant potential drug interactions was identified. Keywords: benzodiazepines, prescribing patterns, controlled substances

    Objective:To determine the chemical composition, total phenolic and total flavonoid contents of the crude extracts from leaves and stems of a Lebanese plant Euphorbia macroclada schyzoceras (E. macroclada), and to evaluate their antioxidant potential using DPPH, H2O2, and chelating of ferrous ions tests. Methods:Quantification of the total phenolic and total flavonoid contents of the crude extracts from leaves and stems and the antioxidant activities were evaluated using spectrophotometric analyses. The chemical composition has been estimated using different techniques such as IR, LC/MS and NMR. Results:Ethanolic extract from leaves of E. macroclada was better than aqueous extract and showed higher content in total phenolic and total flavonoid than found in the stems. On the other hand, using DPPH and H2O2 tests, this extract from leaves showed higher antioxidant capacity than aqueous extract. However, using the chelating of ferrous ions test, the antioxidant activity of the aqueous extract of both stems and leaves was stronger than that of ethanolic once. The chemical composition of the whole plant showed the presence of some aromatic compounds and fatty acids. Conclusions:Both ethanolic and water extracts from both parts of this plant are effective and have good antioxidant power. So, this plant can be used in the prevention of a number of diseases related to oxidative stress.

    Full Text Available Background. It is well established that the Mediterranean and Arab populations are at high risk for thalassemias in general and for alpha-thalassemia in particular. Yet, reports on alpha-thalassemia in Lebanon are still lacking. In this study, we aim at assessing the incidence of alpha-thalassemia in the Lebanese population. Methods. 230 newborns’ dried blood cards remaining from routine neonatal screening at the American University of Beirut Medical Center were collected for DNA extraction. Samples were screened for the 21 most common α-globin deletions and point mutations reported worldwide, through multiplex Polymerase Chain Reaction (PCR and Reverse-Hybridization technique. Results. Upon analyses, the carrier rate of α-thalassemia was found to be 8%. Two mutations detected the −α3,7 single gene deletion found in 75% of cases and the nongene deletion α2 IVS1 [−5nt] in the remaining samples. Conclusion. This study is the first dedicated to investigate α-thalassemia trait incidence in Lebanon. Data obtained demonstrates a high carrier rate in a relatively, highly consanguineous population; it also highlighted the presence of two common mutations. These results may be of an important impact on premarital and newborn screening policies in our country.

    Domestic violence is a worldwide epidemic. This study examines the effects of narrative exemplars and a celebrity spokesperson in anti-domestic violence ads on Lebanese college students' attitudes and beliefs towards domestic violence and whether these effects are impacted by personal experience. The practical significance is derived from the high prevalence of domestic violence internationally, making it important to find ways to effectively use media to address this health-related issue that has huge consequences for the individual and society. This study adds to the theoretical understanding of narrative persuasion and media effects. Results indicated that narrative exemplars in anti-domestic violence ads promoting bystander awareness and intervention were more beneficial for people without relevant experience compared to people who know someone affected by domestic violence. Anti-domestic violence ads without narrative exemplars, but that also featured an emotional self-efficacy appeal targeting bystanders, were more effective for participants who know someone who had experienced domestic violence compared to participants without relevant experience. The presence of a celebrity spokesperson elicited more positive attitudes about the ad than a noncelebrity, but failed to directly affect relevant anti-domestic violence attitudes or beliefs. These results highlight the significance of formative audience research in health communication message design.

    Coping strategies used by Multiple Sclerosis patients play a key role in adjusting to the disease and affect their overall quality of life. This relationship has been investigated in developed countries, but none has been studied in developing ones such as Lebanon. Factors including barriers to health care delivery, economic pressure and political instability influence which coping strategies are used and often increases the use of negative coping mechanisms. The current pilot study explored the association between different coping strategies with quality of life and depression, anxiety, fatigue and social support in 34 Lebanese Multiple Sclerosis patients. Results indicated that Multiple Sclerosis patients using positive coping strategies had significantly higher scores of quality of life (U=46, p=.038) and social support (U=33.5, p=.011), and lower depression (U=44, p=.030) and anxiety levels (U=46.5, p=.038) as compared to those using negative coping strategies. Specifically, escape avoidance coping strategy was associated with poor quality of life scores (r=-.609, pstrategies is needed to develop proper therapeutic interventions which increase quality of life. Future studies are required to confirm these results. Copyright © 2015 Elsevier B.V. All rights reserved.

    Introduction six million of deaths are due today to stroke, while stroke survivors will depend on their caregivers at home. As the literature noted in, these caregivers meet challenges and satisfactions, encouraging them to resort to adaptation strategies in order to cope with their care situation. The purpose of this article is to describe and understand the experience of Lebanese family caregivers who take care at home of a relative stroke survivor. Using the phenomenological approach of Giorgi (1997), twelve interviews were conducted with six family caregivers who have been recruited through a rehabilitation center in Beirut. Eight themes have emerged from the phenomenological analysis: the family caregiver burden, the missing social support, the learning through his experience of a family caregiver, the contribution to caregiving survivor, the selflessness in the caregiving, the gratitude in the caregiving, the familiarization with new routines and reconciliation with new lifestyle. The proposed essence from this phenomenological analysis is: the satisfaction in taking care of the stoke survivor by facing challenges and bringing order into the chaos caused by the stroke. The knowledge gained from this study would allow nurses to identify family caregivers at risk in order to help them to adapt to their new role as caregivers, and to develop health promotion strategies, taking into consideration their experience.

    Full Text Available Hemoglobinopathies are highly prevalent diseases and impose a public health burden. Early diagnosis and treatment can ameliorate the course of these diseases and improve survival. Despite purported high incidence of hemoglobinopathies in Lebanon, there are no nationwide screening programs. In this study, newborn screening utilizing high pressure liquid chromatography was executed in all public hospitals across Lebanon between 2010 and 2013. All newborns with an abnormal hemoglobin (Hb were offered genetic counseling and all those with disease were enrolled in comprehensive hemoglobinopathy clinics. Among newborns, 2.1% were found to have an abnormal Hb variant with sickle Hb being the most common while 0.1% were found to have sickle cell disease (SCD. The majority of those with SCD had non-Lebanese origins. The most common causes of hospitalizations in infants with SCD were acute splenic sequestration and pain crises. No bacteremia or other life threatening infections were noted. At a median follow up 14 months (follow up range 7 to 34 months, all children with disease are alive and compliant with treatment. Systematic screening for SCD and other Hb variants was shown to be feasible, cost effective, and of accurate predictive value. This program was also clinically effective because it led to the identification of babies with disease and to providing them with free early multidisciplinary care. Conclusively, a newborn screening program should be implemented across Lebanon to detect hemoglobinopathies and initiate early therapeutic and preventive strategies and genetic counseling.

Materials and Methods: A nonrandomized prospective comparative case study was performed on 57 eyes; of which, 54 were myopia and 3 were hyperopia. Twenty-four patients had artisan pIOL implantation and 33 had artiflex pIOL implantation. Higher-order aberration (HOA and CS were obtained 1 year after surgery. Results: Total HOA in artisan group was greater than artiflex group (P = 0.044 with a mean HOA of 0.44 ± 0.15 root mean square (RMS for artisan and 0.35 ± 0.15 RMS for artiflex. Although, there were no significant differences in the vertical trefoil, vertical coma, horizontal trefoil, horizontal coma, secondary astigmatism, quatrefoil, and fourth order spherical aberration in two groups. CS in mesopic conditions was better in artiflex-treated eyes at three spatial frequencies of 6, 12, and 18 cycles per degree (cpd (P = 0.003, P = 0.007, and P = 0.00, respectively, and no significant difference was seen between two lenses at 3 cpd. Conclusion: Although the components of HOA were not significantly different between two groups, total HOA was higher in artisan group, which may be due to the slight differences in each component, increasing the HOA as a total. CS was significantly better in artiflex group.

    Full Text Available The aim of the present study was to investigate the prevalence of S. aureus in raw sheep milk cheese and to assess the enterotoxigenic profile of the isolated strains. N.16 raw milk sheep cheese, collected from 8 artisan dairies, were analyzed to detect the presence of Coagulase Positive Staphylococci (CPS. In the frame of Regulation (EC No 2073/2005 cheese samples were tested for the presence of staphylococcal enterotoxins (SEs when a CPS count >105 cfu/g was detected. CPS isolates identified as S. aureus were analyzed using multiplex PCR for the detection of classical (sea-see and enterotoxins-like (seh, sek, sel, sem, seo, sep genes. S. aureus was recovered in all cheese samples and in 50% with levels >105 cfu/g. 14 strains carried at least one of the genes coding for enterotoxins. In none of the cheese samples SEs were detected. Although a correct acidification (pH 5.1-5.4 at 6 hours was observed in dairies using natural starter culture, in cheese samples obtained from these dairies, CPS counts were greater (P<0.05 as compared with those where starter culture were not used. This result might be related to the main role of microbial competition on the control of S. aureus in early stage of cheesemaking. Further research is needed to better understand the effect of lactic acid bacteria competition on the growth of S. aureus.

  9. HIV/AIDS, artisanal fishing and food security in the Okavango Delta, Botswana

    Ngwenya, B. N.; Mosepele, K.

    Generally, rural households pursue all year round natural and non-natural resource-based livelihood systems to diversify these options in order to cope with risks emanating from a range of shocks and stressors. Artisanal fishing in the Delta is not only a major livelihood option but also a source of food security. This paper is based on analysis of primary data collected from a survey of 248 subsistence fishers’ households through simple random sampling in 22 villages in the Delta. The overall objectives of the survey were to assess the general prevalence of HIV/AIDS in the Ngamiland district of Botswana, to investigate potential effects of AIDS-related stressors, particularly chronic illness on artisanal fishing activities, and to assess implications towards food security. Results from this study indicate that HIV prevalence rates for pregnant women attending antenatal clinics in the Delta are approximately 30% and are related to factors such as marriage, education, and employment. Despite this relatively high prevalence percentage, most of the affected households do not have adequate access to HIV/AIDS support facilities. Support services are provided on the basis of population size and/or status of the settlement (i.e. urban, urban village, rural or remote). Therefore, since about 50% of the Delta’s population lives in settlements of less than 500 people, they receive health services indirectly through major population centres whose capacity to deliver timely HIV/AIDS services is limited. This disproportionate access to HIV/AIDS services disadvantages the majority of fishing communities in the Delta, and may affect their ability to fish. Moreover, about 53% of sampled households had cared for a continuously ill person/s (CIP’s) in the last 5 years, out of which approximately 29% felt that this seriously impacted fishing activities. These serious impacts included sale of family assets, depletion of savings, and switching or abandoning fishing activities

    Farah J Nassar

    Full Text Available Relative to western populations, the percentage of women diagnosed with breast cancer at a young age in Lebanon is high. While the younger age of the Lebanese population compared to the West certainly contributes to this difference, potential genetic, reproductive and/or biological factors likely play an important role. The objective of this study is to investigate the contribution of miRNAs in this setting through the analysis of the expression of five reported dysregulated miRNAs, miR-148b, miR-10b, miR-21, miR-221, and miR-155 in 20 normal and 57 cancerous breast tissues from Lebanese breast cancer patients. After finding their relative expression by quantitative reverse transcription real time PCR, the results were analyzed with respect to the patients' clinical and histopathology presentations. Compared to normal breast tissues, significant upregulation of miR-155, miR-21 and miR-148b, notable downregulation of miR-10b and non-significant expression of miR-221 were observed in tumor tissues. Moreover, miR-10b was significantly underexpressed in estrogen/progesterone receptor (ER/PR negative tumors relative to ER/PR positive tumor tissues. miR-155 was also significantly overexpressed in postmenopausal patients and in those of age at diagnosis greater than 40 years old as well as in PR negative or in human epidermal growth factor 2 (Her2 positive tissues. This study is the first one to report miRNA expression patterns in Lebanese breast cancer patients. We found that differential miRNA expression in breast cancer could be variable between Lebanese and Western populations. miR-10b was positively correlated with the ER and PR status and miR-155 could be a noteworthy biomarker for the menopausal state, age at diagnosis, PR and Her2 status. Hence, miRNA can be used as biomarkers for early breast cancer detection.

    Contrary to the safe practices of milk pasteurization or sterilization, which effectively reduce foodborne outbreaks incidence associated with raw milk and dairy products use, outbreaks caused by such products continue to occur. Despite this fact, a worldwide movement advocating for the rights of raw milk and cheese selling and consumption, due to their specific nutritive characteristics, has strengthened significantly in recent years. Traditional agricultural manufacturers from Serbia still sell products related to thermally unprocessed milk, such as cottage cheese and raw cream. In AP Vojvodina during the period of 1981-2010 a total of 179 foodborne outbreaks were reported, where the incriminated cause of the outbreak were milk or diary. In 126 (70.39%) outbreaks, totaling 2276 sick individuals and one casualty, it was confirmed that the incriminated food was from the group of dairy products. In 48 instances (26.82%), bacteriological tests confirmed that milk and dairy products were excluded as the outbreak causes, while in another 5 (2.79%) outbreaks, microbiological analysis of food failed to confirm any relation to the actual epidemiological instances. In some cases, bacteriological testing of incriminated foods was not possible. In the cases of outbreaks associated with the consumption of milk and dairy products, traditional raw milk products were cited as being used. Consumption of unpasteurized milk and cheese represents public health threat. National and international rules ensuring use of safe products for human consumption have to set rules of trade of thermally processed milk and products on the market.

    Bacanora is a spirituous beverage elaborated with Agave angustifolia Haw in an artisanal process. Natural fermentation is mostly performed with native yeasts and bacteria. In this study, 228 strains of yeast like Saccharomyces were isolated from the natural alcoholic fermentation on the production of bacanora. Restriction analysis of the amplified region ITS1-5.8S-ITS2 of the ribosomal DNA genes (RFLPr) were used to confirm the genus, and 182 strains were identified as Saccharomyces cerevisiae. These strains displayed high genomic variability in their chromosomes profiles by karyotyping. Electrophoretic profiles of the strains evaluated showed a large number of chromosomes the size of which ranged between 225 and 2200 kpb approximately.

    The aim of this paper is to examine the iconography on a set of star charts by Albrecht Dürer (1515), and celestial globes by Caspar Vopel (1536) and Christoph Schissler (1575). The iconography on these instruments is conditioned by strong traditions which include not only the imagery on globes and planispheres (star charts), but also ancient literature about the constellations. Where this iconography departs from those traditions, the change had to do with humanism in the sixteenth century. This "humanistic" dimension is interwoven with other concerns that involve both "social" and "technical" motivations. The interplay of these three dimensions illustrates how the iconography on celestial charts and globes expresses some features of the shared knowledge and shared culture between artisans, mathematicians, and nobles in Renaissance Europe.

    Full Text Available This study seeks to analyze the benefits, as well as the likely risks of cultivating Jatropha curcas in small production units of rain fed lands in Yucatán. In order to analyze the possible development of local artisanal agri-industry in the context of policies related to biofuels in Mexico, interviews with key informants were made to identify the agricultural potential of Jatropha c. in monoculture and associated crops. Its cultivation and using for biodiesel in the country will be possible as long as it not implies competition with crops for family consumption and it not represents an environmental degradation factor. Production of Jatropha c. on small areas could be a productive choice if public policies are established to promote biodiesel production and its use in national industry.

    Full Text Available Rural women's discrimination and the lack of effective implementation of the legislation on gender equality is a phenomenon found around the world. Women have been traditionally the responsible of family care and feeding, thus they have developed productive tasks that allow combining productive and reproductive activities in the farm. Food processing is one of these activities and it allows women to have a paid work or to complement agrarian rents in a context where most of agricultural works are vetoed to them. Nevertheless, women are usually linked to small-scale agricultural projects which prioritize quality and local food production, and the expansion of industrial food systems has worsened the situation of artisan women. In the present research we aimed, through the use of qualitative methodologies, at conducting a diagnosis of the situation of women leading small-scale food transformation projects in Spain while eliciting their main difficulties, needs and claims.

    Objective: To evaluate exploitation status of the stocks of demersal fishes in Omani artisanal fisheries. Methods: Time-series data between 2005 and 2014 on catches and effort represented by the number of fishing boats were used to estimate catch per unit effort and maximum sustainable yields applying Schaefer surplus production model. Regression analyses were made online using GraphPad software. Results: The study revealed that increasing the number of boats on the fishery caused a decrease of catch per unit effort of some species. Maximum sustainable yields and exploitation status were estimated for these species applying. Conclusions: Some demersal fish species were found to be caught in quantities exceeding maximum sustainable yields during some fishing seasons indicating overexploitation of their stocks.

  1.  Miners’ magic: artisanal mining, the albino fetish and murder in Tanzania

    2010-01-01

    A series of murders of albinos in Tanzania’s north-west mining frontier has been shrouded in a discourse of primitivism by the international and national press, sidestepping the significance of the contextual circumstances of an artisanal mining boom firmly embedded in a global commodity chain...... and local profit maximisation. The murders are connected to gold and diamond miners’ efforts to secure lucky charms for finding minerals and protection against danger while mining. Through the concept of fetish creation, this article interrogates the agency of those involved in the murders : the miners who...... purchase the albino charms, the waganga healers renowned for their healing, divination and sorcery skills who prescribe and sell the charms, and the albino murder victims. The agrarian background, miners’ ambitions and a clash of values comprise our starting point for understanding the victimisation...

    As molecular synthesis advances, we are beginning to learn control of not only the chemical reactivity (and function) of molecules, but also of their interactions with other molecules. It is this basic idea that has led to the current explosion of supramolecular science and engineering. Parallel to this development, chemists have been actively pursuing the design of very large molecules using basic molecular building blocks. Herein, we review the general development of supramolecular chemistry and particularly of two new branches: supramolecular coordination complexes (SCCs) and metal organic frameworks (MOFs). These two fields are discussed in detail with typical examples to illustrate what is now possible and what challenges lie ahead for tomorrow's molecular artisans.

    2010-09-01

    Full Text Available This article represents the first ethnospongiological study in Brazil, and it aimed at recording artisanal fishermen’s knowledge about sea sponges and their ecological interactions. The study was carried out in the Ilha do Contrato community at Camamu Bay, Bahia State, Brazil. The data were obtained by means of open-ended interviews and projective tests, and followed the usual techniques of ethnographic surveys. The interviewees had knowledge regarding ecological interactions among fish, sea sponges and sponge endofaunal composition. According to the results, there is some congruence between folk wisdom and scientific knowledge. The importance of integrating local knowledge into management and conservation plans designed for the Camamu Bay region, as well as the set of data on ecology of reef communities, should be considered.

    Full Text Available Background: Health insurance (HI can serve as a vital risk protection for families and small businesses and also increase access to priority health services. This study determined the knowledge, attitude of artisans toward HI as well as their health-seeking pattern and willingness to join the HI scheme. Methodology: This descriptive cross-sectional survey used a multistage sampling technique to recruit 260 participants, using self-designed, pretested, interviewer-administered questionnaire. Data were analyzed using Epi-info version 7.0. Chi-square test, Fisher′s exact test, and logistic regression were used for associations; the level of significance was set at 5%. Results: The respondents were predominantly male, i.e., 195 (75.0%, with a mean age of 32.36 + 6.20 years and mean income of N 29,000 + 5798.5 ($1 ~ N 161. Majority of the respondents, i.e., 226 (86.9% were not aware of HI. The overall knowledge was poor (6.5% and the main source of information was through radio/television (41.2%. Nearly, half of the respondents (33 out of 67 identified the concept of HI as a pool of contributors′ fund for only healthcare service. A high proportion of the respondents (27 out of 34 were aware of the benefits of HI, although majority, i.e., 27 (79.4% identified access to medication as the benefit. The majority of the respondents, i.e., 228 (87.7% expressed negative attitude toward the scheme; however, 76.5% were willing to join the HI scheme. Conclusion: The artisans had low awareness/poor knowledge of HI which translated to a negative attitude toward the scheme. There is need for an aggressive stakeholders′ enlightenment campaign for increasing coverage.

    Full Text Available The aim of this study was to investigate the status of artisanal fisheries in the lower Phongolo River floodplain in northern KwaZulu-Natal, South Africa. A cross-sectional quantitative survey design was used that included the development of a questionnaire and a systematic survey among the five villages bordering the Ndumo Game Reserve. Data were collected over a 5-day period by a group of 16 fieldworkers and analysed using the Statistical Package for the Social Sciences, version 21. The results revealed that fish was the third most consumed protein in the area, that people consumed fish on average twice a week, that at least six fish species (and one recently introduced crayfish species were consumed regularly, and that most fish were obtained from local vendors, who in turn bought it from local fishermen and -women. Fishing activities also appeared to occur predominantly along the river system and targeted mainly red-breasted tilapia (Tilapia rendalli and Mozambique tilapia (Oreochromis mossambicus and, to a slightly lesser extent, African sharptooth catfish (Clarias gariepinus and brown squeaker (Synodontis zambezensis.Conservation implications: Given that Ndumo residents predominantly catch fish by means of non-commercial methods, that they do so for reasons of personal consumption and subsistence, and that they mostly target rivers and dams rather than the ecologically sensitive pans in the region, it would seem likely that fishing in the region might be sustainable for the moment. However, it is recommended that studies on the local fish populations and their reproductive rates be conducted so that the actual impact on local fish populations can be determined more accurately. This study serves to provide the necessary baseline data on fish utilisation in the region, which would enable the impact of artisanal fishing on fish reserves in the Ndumo region to be determined once population studies have been completed.

    2013-01-01

    Background: In 2010, Médecins Sans Frontières discovered a lead poisoning outbreak linked to artisanal gold processing in northwestern Nigeria. The outbreak has killed approximately 400 young children and affected thousands more. Objectives: Our aim was to undertake an interdisciplinary geological- and health-science assessment to clarify lead sources and exposure pathways, identify additional toxicants of concern and populations at risk, and examine potential for similar lead poisoning globally. Methods: We applied diverse analytical methods to ore samples, soil and sweep samples from villages and family compounds, and plant foodstuff samples. Results: Natural weathering of lead-rich gold ores before mining formed abundant, highly gastric-bioaccessible lead carbonates. The same fingerprint of lead minerals found in all sample types confirms that ore processing caused extreme contamination, with up to 185,000 ppm lead in soils/sweep samples and up to 145 ppm lead in plant foodstuffs. Incidental ingestion of soils via hand-to-mouth transmission and of dusts cleared from the respiratory tract is the dominant exposure pathway. Consumption of water and foodstuffs contaminated by the processing is likely lesser, but these are still significant exposure pathways. Although young children suffered the most immediate and severe consequences, results indicate that older children, adult workers, pregnant women, and breastfed infants are also at risk for lead poisoning. Mercury, arsenic, manganese, antimony, and crystalline silica exposures pose additional health threats. Conclusions: Results inform ongoing efforts in Nigeria to assess lead contamination and poisoning, treat victims, mitigate exposures, and remediate contamination. Ore deposit geology, pre-mining weathering, and burgeoning artisanal mining may combine to cause similar lead poisoning disasters elsewhere globally.

    2013-10-15

    Participatory research has become increasingly common in natural resources management. Even though participatory research is considered a strategy to facilitate co-management, there is little empirical evidence supporting this. The objective of the present paper is to analyze the contributions of participatory research to help encourage the emergence of co-management, based on a case study in Piriápolis artisanal fishery in coastal Uruguay (where management has been top-down). We argue that participatory research involving artisanal fishers, government, and other stakeholders (university scientists and NGOs) can be a key stimulus towards co-management. We build this argument by considering "seven faces" by which co-management can be analyzed: (1) as power sharing; (2) as institution building; (3) as trust building; (4) as process; (5) as learning and knowledge co-production; (6) as problem solving; and (7) as governance. Our findings show that participatory research had an impact on these various faces: (1) power was shared when making research decisions; (2) a multi-stakeholder group (POPA), with a common vision and goals, was created; (3) trust among participants increased; (4) the process of group formation was valued by participants; (5) stakeholders learned skills for participation; (6) two problem-solving exercises were conducted; and (7) a diversity of stakeholders of the initial problem identified by fishers (sea lions' impact on long-line fishery) participated in the process. The case shows that participatory research functions as a platform which enhances learning and knowledge co-production among stakeholders, paving the way towards future co-management.

    2015-02-01

    Full Text Available Artisanal small-scale mining (ASM has devastating impacts on the environment, such as deforestation, over-stripping of overburden, burning of bushes and use of harmful chemicals like mercury. These environmental impacts are a result of destructive mining, wasteful mineral extraction and processing practices and techniques used by the artisanal small-scale miners. This paper explores the ecological problems caused by ASM in Mzingwane District, Zimbabwe. It seeks to determine the nature and extent to which the environment has been damaged by the ASM from a community perspective. Interviews, questionnaires and observations were used to collect qualitative data. Results indicated that the nature of the mining activities undertaken by unskilled and under-equipped gold panners in Mzingwane District is characterised by massive stripping of overburden and burning of bushes, leading to destruction of large tracts of land and river systems and general ecosystem disturbance. The research concluded that ASM in Mzingwane District is an ecological time bomb, stressing the need for appropriate modifications of the legal and institutional frameworks for promoting sustainable use of natural resources and mining development in Zimbabwe. Government, through the Ministry of Small Scale and Medium Enterprises, need to regularise and formalise all gold mining activities through licensing, giving permanent claims and operating permits to panners in order to recoup some of the added costs in the form of taxes. At the local level, the Mzingwane Rural District Council (MRDC together with the Environmental Management Agency (EMA need to design appropriate environmental education and awareness programmes targeting the local community and gold panners.

    The Infant Feeding Intentions (IFI) scale was shown to reliably measure maternal intentions to initiate breastfeeding and continue exclusive breastfeeding until 1, 3, or 6 months in English and Spanish but not in Arab contexts. Research aim: This study aimed to validate an Arabic version of the IFI scale (IFI-A) and examine its ability to predict exclusive breastfeeding at 1, 3, or 6 months in pregnant Lebanese women. The internal consistency reliability and construct validity of the IFI-A scale were tested on 50 pregnant women (Group 1), whereas its predictive ability was tested on 196 pregnant women (Group 2), who were surveyed monthly about their infants' nutrition method until 6 months. The IFI-A scale's Cronbach's alpha internal consistency reliability is .82. Its corrected item-total correlations ranged from .26 for Item 2 ("at least give breastfeeding a try") to .86 for Item 4 ("will be exclusively breastfeeding at 3 months"). Exploratory factor analysis revealed that it is unidimensional. IFI-A scores correlated significantly with exclusive breastfeeding duration in Group 1 ( r = .624; p = .001) and with participants' breastfeeding attitude ( r = .390; p scale predicted exclusive breastfeeding at 3 months, albeit weakly (odds ratio = 1.16; 95% confidence interval [0.99, 1.36]), but not at 1 or 6 months. The IFI-A scale is a reliable and valid tool to assess maternal feeding intentions and predict exclusive breastfeeding at 3 months in the Arab context. Further studies are needed in other Arab contexts to confirm our findings.

    Full Text Available Abstract Background Although the health benefits of breastfeeding are well established, early introduction of formula remains a common practice. Cultural beliefs and practices can have an important impact on breastfeeding. This paper describes some common beliefs that may discourage breastfeeding in Lebanon. Methods Participants were healthy first-time mothers recruited from hospitals throughout Lebanon to participate in a study on usage patterns of a telephone hotline for postpartum support. The hotline was available to mothers for the first four months postpartum and patterns of usage, as well as questions asked were recorded. Thematic analysis of the content of questions which referred to cultural beliefs and practices related to breastfeeding was conducted. Results Twenty four percent of the 353 women enrolled in the study called the hotline, and 50% of the calls included questions about breastfeeding. Mothers expressed concern about having adequate amounts of breast milk or the quality of their breast milk. Concerns that the mother could potentially harm her infant though breastfeeding were rooted in a number of cultural beliefs. Having an inherited inability to produce milk, having "bad milk", and transmission of abdominal cramps to infants through breast milk were among the beliefs that were expressed. Although the researchers live and work in Lebanon, they were not aware of many of the beliefs that are reported in this study. Conclusion There are a number of cultural beliefs that could potentially discourage breastfeeding among Lebanese women. Understanding and addressing local beliefs and customs can help clinicians to provide more culturally appropriate counselling about breastfeeding.

    The prevalence of dyslipidelmia in pediatric Middle-Eastern populations is unknown. Our study aims to investigate the distribution and correlates of non-high-density lipoprotein cholesterol (non-HDL-C) and triglycerides among Lebanese school children. A total of 969 subjects aged 8-18 years were included in the study (505 boys and 464 girls). Recruitment was done from 10 schools located in the Great Beirut and Mount-Lebanon areas. Non-fasting total cholesterol, triglycerides, and HDL-cholesterol (HDL-C) were measured. Non-HDL-C was calculated. Schools were categorized into 3 socioeconomic statuses (SESs; low, middle, and high). In the overall population, the prevalence of high non-HDL-C (>3.8 mmol/L), very high non-HDL-C (>4.9 mmol/L), and high triglycerides (>1.5 mmol/l) are respectively 9.2%, 1.24%, and 26.6%. There is no significant gender difference for non-HDL-C or triglycerides. Non-HDL-C and triglycerides are inversely correlated with age in girls (P triglycerides are higher in children from lower SES schools. After adjustment for age and body mass index (BMI), testosterone is inversely associated with triglycerides in boys (P triglycerides are independently associated with BMI and schools' SES in both girls and boys. This study confirms, in our population, the association between obesity and both high non-HDL-C and triglycerides, and between high triglycerides and low SES.

    Since the early 1990s, international recommendations have promoted folic acid supplementation during the periconception period as an effective way of preventing neural tube defects (NTDs). However, the adoption of this recommendation remains insufficient. To assess the awareness and actual intake of folic acid among married Lebanese women aged 18-45 years, a cross-sectional study was conducted among 600 women selected from all five administrative districts in Lebanon, using a multistage cluster sampling procedure. An anonymous questionnaire was completed which covered measures of knowledge and use of folate supplements, as well as demographic, socioeconomic and obstetrical factors. Sixty percent of surveyed women (60%; n = 360) had heard about folic acid. Doctors were the most frequent source of information (61.1%) but only 24.7% of women have been told of the correct period during which folic acid supplementation was useful. Overall, only 6.2% had taken folic acid tablets during the adequate period. Younger age, higher education level and stability/sufficiency of income appeared to be significant predictors of awareness among Lebanese women. Actual folic acid intake was significantly associated with younger age, higher number of pregnancies, planning the last pregnancy and having had that last one after 1990. In Lebanon, the level of folic acid awareness and adequate intake remain relatively low. Several approaches should be used to promote folic acid intake including awareness campaigns, and routine counseling by primary health care physicians on folic acid during preconception visits.

Antimicrobial activity and high thermostability of a novel BLIS secreted by Enterococcus Mundtii isolated from lebanese cow’s milk. 2016. Lebanese Science Journal, 17(2: 166-176. Lactic acid bacteria (LAB are used in many fields such as fermentation agents, increasing nutritional value and improving organoleptic quality of food. Also they are used as probiotics and preservatives against pathogens and spoilage microbes by producing antimicrobial substances such as bacteriocins. Fifty cow’s milk samples were collected and 175 LAB isolates were isolated and identified by using biochemical method. Fifteen isolates showed an antimicrobial activity against Listeria monocytogenes ATCC® 19115™. One strain, BL4 which showed the strongest activity, was chosen to extract and characterize its antimicrobial substance in order to evaluate its potential use as a new food protective agent. This strain was identified as Enterococcus mundtii by pyrosequencing method. The active substance was extracted using solvent method. This Bacteriocin like Inhibitory Substances “BLIS” can support a high temperature (121 ˚C for a long time and resist pH variation. The BLIS BL4 can be considered as a peptide active against many food pathogen and food-spoilage microbes, such as Listeria monocytogenes and Penicillium spp. BLIS BL4 can be used in food application as bio-preservative to reduce food-spoilage and food-borne diseases in food products.

    Exposure to mycotoxins may be associated with carcinogenic, immunosuppressant and estrogenic effects. In the Middle-East, studies investigating food contamination and dietary exposure to mycotoxins are particularly scarce. This study aims at evaluating the dietary exposure of an adult Lebanese urban population to four mycotoxins (AFB1, AFM1, OTA, DON) classified as priority food contaminants by the WHO. Dietary exposure assessment was performed by means of the total diet study approach. Average and excessive consumer exposure estimates (p95) were calculated and compared with appropriate toxicological reference values (TRVs). Average dietary exposure levels to OTA and DON represented 29.9% and 156.8% of the respective TRVs, with the p95 exposure estimates approaching or exceeding the TRVs for these mycotoxins (95.1% and 355.8%, respectively). Based on the mean dietary exposure level to AFB1, cancer risk was estimated at 0.0527-0.0545cases/100,000persons/year, while mean exposure to AFM1 was associated with a population risk of 0.0018-0.0027cases/100,000persons/year. The study's findings place Lebanon among countries that are highly exposed to mycotoxins through the diet and call for larger-scale studies aiming at providing a comprehensive assessment of the dietary exposure of the Lebanese population to mycotoxins as well as to other food contaminants.

    Full Text Available Considerable efforts have been devoted to map the relations between the home environment and selected aspects of child’s development. A recent instrument was developed that aimed at assessing the affordances in the home environment, the AHEMD-SR. Although the AHEMD-SR gave insight into affordances in the home, it was focused on two specific populations from the United States and Portugal. Currently, there is limited research regarding the validity of this instrument when used in different cultures. The purpose of this study was to compare a sample of Middle Eastern children to the normative sample that was used to validate the AHEMD. Results showed a significance difference between the socioeconomic statuses between the groups. Concerning factor analysis, results showed that the Lebanese group had five factors loading as did the American/Portuguese sample but with variables loading differently. Interestingly, the Lebanese group showed higher scores for affordances inside the home such replica toys and games. Our findings show that the state of the environment may play a role in the affordances and development. Future work is needed to look at the specific loading and possible variables that may be included in the AHMED-SR to look at other cultures that may have other limitations.

    Full Text Available Contrary to the safe practices of milk pasteurization or sterilization, which effectively reduce foodborne outbreaks incidence associated with raw milk and dairy products use, outbreaks caused by such products continue to occur. Despite this fact, a worldwide movement advocating for the rights of raw milk and cheese selling and consumption, due to their specific nutritive characteristics, has strengthened significantly in recent years. Traditional agricultural manufacturers from Serbia still sell products related to thermally unprocessed milk, such as cottage cheese and raw cream. In AP Vojvodina during the period of 1981-2010 a total of 179 foodborne outbreaks were reported, where the incriminated cause of the outbreak were milk or diary. In 126 (70.39% outbreaks, totaling 2276 sick individuals and one casualty, it was confirmed that the incriminated food was from the group of dairy products. In 48 instances (26.82%, bacteriological tests confirmed that milk and dairy products were excluded as the outbreak causes, while in another 5 (2.79% outbreaks, microbiological analysis of food failed to confirm any relation to the actual epidemiological instances. In some cases, bacteriological testing of incriminated foods was not possible. In the cases of outbreaks associated with the consumption of milk and dairy products, traditional raw milk products were cited as being used. Consumption of unpasteurized milk and cheese represents public health threat. National and international rules ensuring use of safe products for human consumption have to set rules of trade of thermally processed milk and products on the market.

    Adolescent obesity is associated with both immediate and longer-term health implications. This study aims to identify dietary patterns among a nationally representative sample of Lebanese adolescents aged between 13 and 19 years (n 446) and to assess the association of these patterns with overweight and obesity. Through face-to-face interviews, socio-demographic, lifestyle and anthropometric variables were collected. Dietary intake was assessed using a sixty-one-item FFQ. Dietary patterns were derived by factor analysis. The following two dietary patterns were identified: Western and traditional Lebanese. The Western pattern was characterised by high consumption of red meat, eggs and fast-food sandwiches. The traditional Lebanese pattern reflected high intakes of fruits and vegetables, legumes and fish. Female sex and a higher maternal education level were associated with a greater adherence to the traditional Lebanese pattern. As for the Western pattern, the scores were negatively associated with crowding index, physical activity and frequency of breakfast consumption. After adjustment, subjects belonging to the 3rd tertile of the Western pattern scores had significantly higher odds of overweight compared with those belonging to the 1st tertile (OR 2·3; 95% CI 1·12, 4·73). In conclusion, two distinct dietary patterns were identified among adolescents in Lebanon: the traditional Lebanese and the Western, with the latter pattern being associated with an increased risk of overweight. The findings of this study may be used to guide the development of evidence-based preventive nutrition interventions to curb the obesity epidemic in this age group.

    Full Text Available In a general context of fisheries decline due to overfishing and to other phenomena such as climate change, it appears to be crucial to implement a sustainable management of natural resources by finding a balance between conservation and exploitation purposes. Artificial reefs (ARs have recently become one of the existing management tools, often in combination with fishing quotas or marine protected areas. To evaluate the effectiveness of the studied ARs, different methods have been used: (i visual census by SCUBA diving (AR scale, (ii fisheries landings survey (local scale and (iii external fish tagging (regional scale. Underwater visual census (UVC showed a significantly higher species richness and density in ARs than in the control site. Abundance, biomass and LPUE data (Landings Per Unit Effort issued from artisanal fisheries landings survey were not significantly different around the AR system from other fishing grounds of the French Catalan coast. The tagging experiments on Diplodus sargus suggested that the connectivity of demersal fish populations must be taken into account to evaluate the influence area of ARs and thus their indirect impacts on artisanal fisheries. The present study highlights the interest of combining methods covering different spatial scales in order to evaluate direct and indirect impacts of ARs on artisanal fisheries. Methods for the evaluation of AR efficiency are discussed.Dentro do atual contexto de redução nos estoques de peixes ligados à sobrepesca, e também à outros fenômenos tais como as mudanças climáticas, é indispensável implementar um plano de gestão durável para os recursos pesqueiros, conciliando sua exploração e conservação.

    Full Text Available Institutional Analysis and Development (IAD studies how institutions (the rules of the game of a society determine the performance of a social-economic system. Elinor Ostrom extends the institutional analysis to the collective action for a particular case, the study of the social-ecological systems (SESs. Any group that attempts to manage a common resource (e.g. aquifers, pastures for optimal sustainable production must solve a set of problems in order to create institutions to facilitate collective action. Some evidences show that following a set of design principles in creating institutions can lead to overcome these problems. The aim of the paper is to apply the SES framework to an artisanal fishery community in Argentina in order to: 1 describe the principal features, key variables and relations of the small-scale fishery system; 2 detect the principal drivers of a potential common-management and the leading detractors from the current communal performance; and 3 analyze the possibility that a self-governing for sustainable fishery may appear. Several drivers for potential common-management and some detractors from the current common performance are summarized. Artisanal fishery SES is currently at a bifurcation point. A common historical and cultural root, the presence of leaderships, the relevance of local knowledge, the dependence on the resource to sustainable livelihoods and the threat of big-scale fisheries area have generated incentives to collective-action. But, simultaneously, internal conflicts are the most important barrier for an integrated community-based management. The heterogeneity among actors and the relevant external conditions have resulted in two groups diverging in their self-organization. The work is framed by the project COMET-LA (COmmunity-based Management of Environmental challenges in Latin America; European Commission’s Seventh Framework Programme of Research and Development, which aims to identify sustainable

    Full Text Available Background: Influenza is a common preventable infectious disease associated with high mortality and morbidity. Vaccination is the most cost-effective measure to prevent influenza, yet the vaccine uptake is known to be low. No previous studies have assessed the rate of seasonal influenza vaccination use among the Lebanese population, nor examined the knowledge and attitudes towards the influenza vaccine. Methods: A cross-sectional survey was performed in 30 pharmacies randomly selected across Lebanon. A 19-item questionnaire was used to record influenza vaccination status, knowledge and attitudes towards the influenza vaccine among the Lebanese general population. Results: The survey response rate was 93%. Among the 640 study participants, the overall 2014-2015 seasonal influenza vaccination rate was 27.6%. The majority of participants (72.4% reported irregular uptake of the vaccine. Results of the multivariate analysis revealed that elderly people (OR = 2.25, CI = 1.08–4.71, with higher education (OR = 1.42, CI = 1.09–1.84, higher physical activity (OR significantly higher than 1 for all categories, and chronic respiratory disease (OR = 3.24, CI = 1.58–6.62 were more regularly vaccinated, while those who visit the doctor “only when needed” (OR = 0.55, CI = 0.34–0.88 and those who consume more than seven drinks/week (OR = 0.24, CI = 0.09–0.65 were less regularly vaccinated. When introducing knowledge and attitude variables to the model, “thinking that the vaccine was not needed” was the only correlate that demonstrated a significant inverse association with regular influenza vaccination (OR = 0.15; p = 0.017. Conclusions: Suboptimal vaccination rates exist among the Lebanese ambulatory adult population. Clear misinformation on the importance of regular influenza immunization is also highlighted. This evidence underscores a compelling need to raise public awareness regarding the efficacy of the influenza vaccine.

    Pierre-Joseph Macquer (1718-1784) is well known as one of the major chemists in the eighteenth century as a theoretician and a teacher. He is also known for his works on dyeing. This paper presents a new face of Macquer. He proposed a theory on mordants in dyeing as early as 1775. Besides his activity at the Académie des sciences, he played an important role in Government as the commissioner of dyeing from 1766 where he established close links with artisan inventors. Académicien chimiste at the royal Manufactory of Sèvres from 1757, he was also the inventor of French porcelain. His notebooks show his organization, method, courage, passion and obstinacy in the search for the paste for hard porcelain. He also proposed an interpretation of its formation. Macquer was both a theoretician and a practical expert in dyeing as well as in porcelain making. He managed to bridge the gap between science and art.

    Lactic acid bacteria (LAB) and coagulase negative cocci (CNC) were isolated from artisanal dry sausages sampled from the northeastern region of Chaco, Argentina. In order to evaluate their performance in situ and considering technological features of the isolated strains, two mixed selected autochthonous starter cultures (SAS) were designed: (i) SAS-1 (Lactobacillus sakei 487 + Staphylococcus vitulinus C2) and (ii) SAS-2 (L. sakei 442 + S. xylosus C8). Cultures were introduced into dry sausage manufacturing process at a local small-scale facility. Microbiological and physicochemical parameters were monitored throughout fermentation and ripening periods, while sensory attributes of the final products were evaluated by a trained panel. Lactic acid bacteria revealed their ability to colonize and adapt properly to the meat matrix, inhibiting the growth of spontaneous microflora and enhancing safety and hygienic profile of the products. Both SAS showed a beneficial effect on lipid oxidation and texture of the final products. Staphylococcus vitulinus C2, from SAS-1, promoted a better redness of the final product. Sensory profile revealed that SAS addition preserved typical sensory attributes. Introduction of these cultures could provide an additional tool to standardize manufacturing processes aiming to enhance safety and quality while keeping typical sensory attributes of regional dry fermented sausages.

    In this work a methodology to evaluate the sensory properties of honeys has been developed. The sensory analysis was carried out by means of a quantitative descriptive analysis (QDA) method, based on several reference scales, for the coverage of the designed range for each descriptor. The peculiarity of this sensory analysis is that the reference scales have been constituted by common foodstuffs agreed upon by consensus of the panel. The main sensory attributes evaluated in the analyses were: adhesiveness, viscosity, bitterness, aroma, sweetness, acidity, color and granularity. Both the intensity and persistence of honey aromas have also been estimated, together with the classification of the identified aromatic attributes into different groups. The method was applied to 55 artisanal honeys from Madrid (Spain) with the following results: (i) the developed sensory profile sheet allowed a satisfactory description of Madrid honeys; (ii) correlations between sensory attributes of three broad groups of Madrid honeys were obtained and (iii) aroma persistence, sweetness, bitterness, color and granularity appeared as the main sensorial characteristics of honey with discrimination power between floral and honeydew honeys.

    Pulque is a traditional fermented alcoholic, acidic, viscous drink of the Mexican central highlands. Its production from the "aguamiel" (sap) of agave plants dates back ~1,500 years and continues to be made by artisanal methods. However, the variability of pulque's quality and its instability hamper its widespread distribution and consumption. Microbiological surveys of pulque from three ranches revealed tremendous variability in the types and quantity of the indigenous microbiota. The population of lactic acid bacteria ranged from 6 × 10(7) to 2 × 10(11) CFU/mL. This variability might be attributed to the conditions on the ranches where the pulque was made. In an attempt to identify these sources of variability, the microbial populations of aguamiel and pulque from a single agave plant were determined. Surprisingly, the population size of the "unfermented" aguamiel and the pulque converged by the end of 3 weeks. The potential use of bacteriocinogenic LAB and known starter cultures to improve pulque properties are discussed.

    Brazilian artisanal "Coalho" cheeses from six Northeast towns were investigated as a functional food based on their peptide profiles and antioxidant, zinc-binding and antimicrobial activities. The peptides (WSP) from "Coalho" cheese showed high antioxidant activity, the best value of TEAC being 2223±10.10μM, which means 91.1±0.43% oxidative inhibition and peptide concentration for IC(50) of 7mg/mL (21μg of peptides) for sample from the town of Correntes. The smallest TEAC value (1896±17μM), which means 75.9±0.7% oxidative inhibition and IC(50) of 10.5mg/mL (31.5μg of peptide), was obtained for samples from the town of São Bento do Una. The zinc-binding activities were: Arcoverde (72.21±0.24%) Cachoeirinha (75.02±0.02%), Capoeiras (61.78±0.65%), Correntes (75.47±0.5%), São Bento do Una (75.41±0.15%), and Venturosa (74.36±0.04%). The WSP extracts showed antimicrobial activity against Enterococcus faecalis, Bacillus subtilis, Escherichia coli and Pseudomonas aeruginosa. All the results obtained suggest that "Coalho" cheese has potential as a functional food. Copyright © 2012 Elsevier Ltd. All rights reserved.

    An average of 209 cases of decompression sickness (DCS) have been reported every year among artisanal fishermen. divers of the Yucatan Peninsula, Mexico. DCS is a major problem among fishermen divers worldwide. This paper explores how diving behavior and fishing techniques among fishermen relate to the probability of experiencing DCS (Pdcs). Fieldwork was conducted in two communities during the 2012-2013 fishing season. Fishermen were classified into three groups (two per group) according to their fishing performance and followed during their journeys. Dive profiles were recorded using Sensus Ultra dive recorders (Reefet Inc.). Surveys were used to record fishing yields from cooperative and individual fishermen along with fishing techniques and dive behavior. 120 dives were recorded. Fishermen averaged three dives/day, with an average depth of 47 ± 2 feet of sea water (fsw) and an average total bottom time (TBT) of 95 ± 11 minutes. 24% of dives exceeded the 2008 U.S. Navy no-decompression limit. The average ascent rate was 20 fsw/minute, and 5% of those exceeded 40 fsw/minute. Inadequate decompression was observed in all fishermen. Fishermen are diving outside the safety limits of both military and recreational standards. Fishing techniques and dive behavior were important factors in Pdcs. Fishermen were reluctant to seek treatment, and symptoms were relieved with analgesics.

    Full Text Available The geography of Punjab, a land-locked region divided between India and Pakistan, makes it an unlikely player in oceanic sojourns. But imperial interventions in Punjab in the middle of the 19th century triggered movements from Punjab that inserted this region in the littoral narrative of the Indian Ocean. Unlike the movements of lascars and traders, who have been central to the revisionist histories of the Indian Ocean, those from Punjab have not featured in oceanic dialogues. The absence of Sikhs in Indian Ocean studies is largely due to the silence of Sikh soldiers, skilled craftsmen and cultivators with largely rural roots who were uprooted to strange lands. The confusion of Sikhs with Hindus, Muslims and, even Afghans, in the colonial era, as well as the classification of Punjabi Muslims as Pakistani in the post-colonial, further problematizes the Sikh migration narrative. Drawing on a wide range of official and unofficial historical sources, this essay argues that twin developments in Punjab, namely the construction of Sikhs as ‘a martial race’ and their integration into the imperial capitalist economy, connects the movements of soldiers and policemen to Shanghai, Hong Kong, the Straits Settlements and Kenya with those of skilled artisans to Mombasa and Uganda. Keywords: Sikhs, Indian Ocean, labour migration, cultural identity

    Full Text Available Scale issues are fundamental in the analysis of temporal and institutional dimensions of fishing territory. To understand actions and decisions at local and regional levels regarding fishing activity, we studied fishing communities at the Ubatumirim Bay, giving particular attention to the Almada community – north coast of the state of São Paulo. Data were collected between 2004 and 2005, a period in which artisanal fishers, officials and representatives of non-governmental organizations were interviewed. The results indicate the absence of territoriality at local level (within the community, but it exists implicitly at regional level (between communities. Both intercommunity relationships and fishing in areas outside the communities contributed to the building of a perception among fishers that “the sea belongs to everyone”. However, such perception that the sea is public does not imply the kind of free access that is unbound by rules. On the contrary, a large number of fishers believe that is important to have some mechanisms of control, and this must be agreed upon by officials and grassroots organizations within a horizontal institutional arrangement, i.e., all the stakeholders must have equal rights to vote and to make decisions.

Significant differences were found between the samples (p £ 0.05 as well as nonconformities in relation to national regulations. The mineral contents showed significant differences between lots of samples (p £ 0.05 and some lots presented Cd and Pb concentrations above the maximum values allowed by Brazilian legislation. High quantities of unwanted materials were detected and none of the samples presented microbiological contamination. The results suggest the creation of technical standards for quality control for the production of rapaduras to ensure food safety.

    Full Text Available The chemical composition of rice hulls produced in an artisan mill and its conversion to fermentable sugars was investigated. The carbohydrate fraction represented 59.2% (w/w of the dry hulls. Cellulose, with 36.6%, was the main component, followed by xylan with 13.9%. An important contribution of starch (8.7% was also detected. The content of ash (19.6% and lignin (15.5% was comparable with that of rice hulls obtained in industrial mills. Dilute-sulphuric acid hydrolysis at different temperatures, from 160 to 210°C, was evaluated for production of fermentable sugars. Due to starch hydrolysis, the concentration of glucose in the hydrolysates produced at 160°C was higher than the values that have previously been reported for industrial sorts of rice hulls under comparable conditions. The xylan-to-xylose conversion increased steadily with increase of the temperature and reached a maximum (67.7% at 190°C. Further increases of the hydrolysis temperature decreased the yield of sugars due to their dehydration to furfural and HMF.

    Full Text Available Regarded as relevant nursery areas for fishes, the estuarine systems shelter many commercially important species. From October 2008 to November 2009, we investigated the ichthyofaunal composition and described the routine of artisanal fishing with camboa net in the estuary at the Cassurubá Extractive Reserve, Bahia, Brazil. Samplings were conducted in three rivers, during the new and full moons. A total of 1,074 fishes were caught in 17 fisheries with nets, belonging to 26 species and 17 families, with a total biomass of 378.4 kg. The Gerreidae and Centropomidae families were the most abundant ones, and there was a predominance of catches. Out of the total, 50% of individuals which were at the first gonadal maturation (L50 described in the literature had a size less than the expected one, indicating growth overfishing. We recommends the establishment of management systems shared between the actors involved in this fishing art and the Cassurubá Extractive Reserve managers, in order to reduce the capture of individuals below the first gonadal maturation size.

  20. Incidental catch of marine turtles by the artisanal fisheries on Santa Catarina Island, SC, Brazil

    Full Text Available The five species of sea turtles, which inhabit the Brazilian shore, have a wordwide distribution and are threatened with extinction. The south of Brazil is characterized as a feeding and breeding area of at least three of these species. The presence of turtles close to the shore and their incidental catch are occurrences reported by artisan fishermen of the Island of Santa Catarina in this work. The study was based on a questionnaire, applied to fishermen and fishfarmers at selected spots on the island. Scientific and popular names were matched using illustrations. The spots with the highest number of events and captures were close to the islands, rocky coasts and stony grounds, i.e. areas related with the foraging habits of the most abundant species, Chelonia mydas. The place, depth and size of the net are characteristics, which influence the capture. The time the net remains in the water is a factor which is fundamental to the survival of the captured turtles. The flesh of the turtle is used as an occasional feeding resource. Capacitation programs and training applied to the communities involved are recommended.

    Yabrudi, Philip F; Diab, Lutfy N

    1978-12-01

    This study was designed to investigate the effects of attitudinal similarity and topic importance on interpersonal attraction when the religion of the stimulus stranger was the same as or was different from that of the S. Each of 80 Lebanese male and female undergraduates at the American University of Beirut responded to an eight-item attitude scale dealing with four important and four unimportant issues, examined later the same scale purportedly filled out by a stranger, and then indicated his attraction toward that stranger. The standard stranger technique was followed which consisted of experimentally manipulating similarity or dissimilarity of a stranger's attitudes and religion with respect to those of the S. The results confirmed the hypothesis in showing that while the variable of religion had no significant effect on interpersonal attraction, the latter was significantly influenced by attitudinal similarity between subject and stranger, particularly on topics considered important by the S.

    2010-02-01

    This cross-sectional study was designed to assess the predictors of coping behaviors of 147 Lebanese parents (101 mothers and 46 fathers) with a child with intellectual disability. It assessed the contribution of child's and parent's characteristics, informal social support, and stress on the coping behaviors of fathers and mothers. Multiple regression analysis confirmed that the father's education, informal social support, and stress were the best predictors of coping. The child's age, severity of illness, and parental health did not significantly contribute to predicting coping behaviors. Contrary to expectations in a Middle Eastern culture, both fathers and mothers reported similar levels of stress, perceived informal social support, and coping. Although informal social support cannot be forced on parents, health professionals can mobilize resources that are culturally sensitive, such as home visitation by nurses or support from other parents. This may especially be beneficial in developing countries with limited resources.

    The chemical and microbiological properties of Lebanese perennial coastal rivers were studied during the dry season extending from July to September 2004. The results indicate significant levels of pollution in all eight rivers. Although many physical and chemical variables were within WHO guidelines for drinking water, coliform levels were unacceptably high indicating pollution from untreated sewage. The most polluted rivers in most categories were the Abu Ali and Antelias. With the exception of bacterial and phosphate loadings, Awali River provides the highest amount of pollution to the Mediterranean mainly due to its high water flow, although it is one of the least polluted rivers. The urgent need for controlling wastewater dumping into river streams is emphasized. The data obtained should serve as a reference point to assess the efficiency of planned wastewater treatment plants.

    2015-01-01

    Recent advances in metabolic profiling techniques allow global profiling of metabolites in cells, tissues, or organisms, using a wide range of analytical techniques such as nuclear magnetic resonance (NMR) spectroscopy and mass spectrometry (MS). The raw data acquired from these instruments are abundant with technical and structural complexity, which makes it statistically difficult to extract meaningful information. Preprocessing involves various computational procedures where data from the instruments (gas chromatography (GC)/liquid chromatography (LC)-MS, NMR spectra) are converted into a usable form for further analysis and biological interpretation. This chapter covers the common data preprocessing techniques used in metabonomics and is primarily focused on baseline correction, normalization, scaling, peak alignment, detection, and quantification. Recent years have witnessed development of several software tools for data preprocessing, and an overview of the frequently used tools in data preprocessing pipeline is covered.

    Full Text Available The natural lactic flora of the artisanal chilli “Tramonti” cheese, a typical product manufactured in the “Lattari mountains”, area of Salerno province (Italy, was investigated. Particular attention was paid to the growth dynamics assessment and to the molecular identification of the indigenous lactic acid bacteria involved in the ripening of this cheese made with raw sheep milk without starter cultures. One batch was monitored taking 4 sample on 0, 30, 50 and 105 ripening days. Lactobacillus and Lactococcus were enumerated and randomly isolated on MRS and LM17 agar (32ºC x 48h -mesophilic flora- and 42°C x 48h -thermophilic flora, respectively. N. 66 presumptive lactic acid bacteria isolates, gram positive and catalase negative, were genotipically identified by Ribotyping. Mesophilic Lactobacillus remained at levels of 107 cfu/g during whole maturation time and thermophilic Lactobacillus, from initial values of 105 cfu/g, reached concentratios of 106 cfu/g at the end of maturation. Mesophilic and thermophilic Lactococcus showed, on average, levels of 106 since the beginning of the ripening. Ribotyping allowed to detect 4 lactic acid bacteria species: Enterococcus faecium (65,15%, Lactococcus lactis spp. cremoris (24,24%, Enterococcus faecalis (6,06% and Enterococcus durans (4,54%, showing the diversity of indigenous lactic acid bacteria of chilli “Tramonti” cheese.

    Full Text Available Fermentation and ripening specificity of traditional cheeses are predominantly directed by the natural microbial community present in milk selected by the cheese-making environment and technology. Therefore the traditional cheeses are unique products with specific microbiota biodiversity. There are several approaches for the identification of microbial population, however all of them have certain advantages and disadvantages. In this study the eligibility and performance of the Biolog phenotypic identification system (Biolog, Inc. with GEN III microplates was tested. Parallel to this method, polymerase chain reaction with genus- and species-specific primers was performed. One hundred sixty-five isolates from nine types of artisan cheeses were isolated and analysed. Cheeses were produced from raw ewe’s milk in Slovenia, Bosnia and Herzegovina, Croatia and Serbia. The Biolog phenotypic identification system identified 90 isolates, but only 55 identifications acquired by the Biolog system were supported by polymerase chain reaction at a genus level and 28 at a species level. The obtained results showed that the reliability of commercial phenotypic identification systems was inadequate when analysing lactic acid bacteria isolates from natural, spontaneous fermentations and needs to be additionally corroborated by genotypic identification methods.

  8. [Two Lebanese villages in the Gulf: village transfers and labour markets].

    Nancy, M

    1985-01-01

    This article analyzes the experiences of 2 cohorts of Lebanese emigrants who departed from 2 dissimilar villages, a large agricultural village called Kfar Rumman with a tradition of significant migration to Kuwait beginning in 1950 and a small village called Kaakour located 30 km from Beirut in which agriculture is secondary to stonecutting and emigration to Saudi Arabia has assumed importance more recently. Among 168 current or formar migrants to Kuwait from Kfar-Rumman, 125 are still in Kuwait, almost all with their families. Members of the same village and family have shown great solidarity over 30 years in helping new migrants find jobs, and their network of friendships and alliances in Kuwait has allowed them to diversify their employment opportunities. Transport and construction were the dominant employment of the 1st 75 migrants who entered Kuwait between 1950-60; they were adroit in building up small businesses in Kuwait and in departing for Saudi Arabia or elsewhere when the construction boom slowed in Kuwait and better opportunities arose elsewhere. Among other jobs, migrants in Kuwait worked in plumbing, furniture making, interior decoration, printing, administrative and other salaried employment in the public or private sector, and iron working and transport. The history of Kfar-Rumman in Kuwait depended greatly on the solidarity and collective life of the village, which greatly reduced the external constraints of the labor market and applied internal economic capacities to the most promising situations. Villagers from Kaakour began migrating to Saudi Arabia in 1958; by 1973 the pace had accelarated greatly due to the oil boom. Until 1974 they had little difficulty establishing themselves as stonecutters and in related trades, but competition increased thereafter with the arrival of stoneworkers from other Arab countries and especially after 1978 with the entrance of Asian workers. Village migrants showed great mobility; most workers were single or left

    2016-01-01

    **Background:** Mercury is used in more than 70 countries to extract gold in artisanal small-scale gold mining (ASGM). The application of mercury is simple and plays a key role in the livelihood for more than 16 million gold miners. Mercury is added to the crushed ore and builds an amalgam with the gold it contains. The amalgam is then smelted, the mercury evaporates, and gold remains. The amalgam smelting is the main source of mercury exposure in ASGM. ASGM is the largest anthropogenic sourc...

    Artisan cheese makers lack access to valid economic data to help them evaluate business opportunities and make important business decisions such as determining cheese pricing structure. The objective of this study was to utilize an economic model to evaluate the net present value (NPV), internal rate of return, and payback period for artisan cheese production at different annual production volumes. The model was also used to determine the minimum retail price necessary to ensure positive NPV for 5 different cheese types produced at 4 different production volumes. Milk type, cheese yield, and aging time all affected variable costs. However, aged cheeses required additional investment for aging space (which needs to be larger for longer aging times), as did lower yield cheeses (by requiring larger-volume equipment for pasteurization and milk handling). As the volume of milk required increased, switching from vat pasteurization to high-temperature, short-time pasteurization was necessary for low-yield cheeses before being required for high-yield cheeses, which causes an additional increase in investment costs. Because of these differences, high-moisture, fresh cow milk cheeses can be sold for about half the price of hard, aged goat milk cheeses at the largest production volume or for about two-thirds the price at the lowest production volume examined. For example, for the given model assumptions, at an annual production of 13,608kg of cheese (30,000 lb), a fresh cow milk mozzarella should be sold at a minimum retail price of $27.29/kg ($12.38/lb), whereas a goat milk Gouda needs a minimum retail price of $49.54/kg ($22.47/lb). Artisan cheese makers should carefully evaluate annual production volumes. Although larger production volumes decrease average fixed cost and improve production efficiency, production can reach volumes where it becomes necessary to sell through distributors. Because distributors might pay as little as 35% of retail price, the retail price needs

  16. From Artisanal to CAD-CAM Blocks: State of the Art of Indirect Composites.

    2016-05-01

    Indirect composites have been undergoing an impressive evolution over the last few years. Specifically, recent developments in computer-aided design-computer-aided manufacturing (CAD-CAM) blocks have been associated with new polymerization modes, innovative microstructures, and different compositions. All these recent breakthroughs have introduced important gaps among the properties of the different materials. This critical state-of-the-art review analyzes the strengths and weaknesses of the different varieties of CAD-CAM composite materials, especially as compared with direct and artisanal indirect composites. Indeed, new polymerization modes used for CAD-CAM blocks-especially high temperature (HT) and, most of all, high temperature-high pressure (HT-HP)-are shown to significantly increase the degree of conversion in comparison with light-cured composites. Industrial processes also allow for the augmentation of the filler content and for the realization of more homogeneous structures with fewer flaws. In addition, due to their increased degree of conversion and their different monomer composition, some CAD-CAM blocks are more advantageous in terms of toxicity and monomer release. Finally, materials with a polymer-infiltrated ceramic network (PICN) microstructure exhibit higher flexural strength and a more favorable elasticity modulus than materials with a dispersed filler microstructure. Consequently, some high-performance composite CAD-CAM blocks-particularly experimental PICNs-can now rival glass-ceramics, such as lithium-disilicate glass-ceramics, for use as bonded partial restorations and crowns on natural teeth and implants. Being able to be manufactured in very low thicknesses, they offer the possibility of developing innovative minimally invasive treatment strategies, such as "no prep" treatment of worn dentition. Current issues are related to the study of bonding and wear properties of the different varieties of CAD-CAM composites. There is also a crucial

    Artisanal and small-scale gold mining (ASGM) offers low-skilled workers an opportunity to elevate themselves out of poverty. However, this industry operates with little to no pollution controls and the cost to the environment and human health can be large. The objectives of this study were to measure levels of arsenic (As), manganese (Mn), cobalt (Co), lead (Pb), and mercury (Hg) in the environment and characterize health risks to miners and residents in an area with active ASGM operations. An exposure assessment was conducted at two different mining sites and a nearby village in the Bolivian Anders. The resulting measurements were then used to quantify cancerous and noncancerous health risks to children and adults working at and living near ASGM areas. Soil concentrations of As were well above background levels and showed great variations between the village and mining area. Mercury vapor levels at the two mining sites were approximately 30 times larger than the EPA reference concentration. The risk of developing non-cancerous health effects were primarily due to exposure to As and Hg. The probability of individuals developing cancer was considerably increased with adult miners having a probability of 1.3 out of 100. Cancer potential was driven by exposure to As, with de minimus cancer risk from all other elements. Based on the environmental characterization of elements in soils and Hg vapors, the risk of developing cancerous and non-cancerous health outcomes were above a level of concern based on EPA risk assessment guidance. Personal protective equipment was not worn by workers and Hg amalgam is commonly heated in workers' homes. Better education of the risks of ASGM is needed as well as simple controls to reduce exposure. Published by Elsevier Inc.

    2015-11-01

    Soils near artisanal and small-scale gold mines (ASGM) have high arsenic (As) contents due to the presence of arsenopyrite in gold ores and accelerated accumulations due to mine wastes disposal practices and other mining activities. We determined the content and speciation to understand the fate and environmental risks of As accumulations in 24 bulk and 12 rhizosphere soil samples collected in the Virgen Del Rosario and the Rayo Rojo cooperative mines in the highlands of Bolivia. Mean total As contents in bulk and rhizosphere soils ranged from 13 to 64 mg kg(-1) and exceeded the soil environmental quality guidelines of Canada. Rhizosphere soils always contained at least twice the As contents in the bulk soil. Elemental mapping using 4×5 μm synchrotron-generated X-ray micro-beam revealed As accumulations in areas enriched with Fe. Results of As-X-ray Absorption Near Edge Spectroscopy (As-XANES) showed that only As(V) species was detectable in all samples regardless of As contents, size fractions and types of vegetation. Although the toxicity of As(V) is less than As(III), we suggest that As uptake of commonly-grazed vegetation by alpaca and llama must be determined to fully understand the environmental risks of high As in soils near ASGM in Bolivia. In addition, knowledge on the speciation of the As bio-accessible fraction will provide another useful information to better understand the fate and transfer of As from soils into the food chain in environments associated with the ASGM in Bolivia and other parts of the world.

    Ricotta cheese is a ready-to-eat product with properties (pH >6.0, aw >0.98-0.99) and moisture content (75-80%) that may pose a risk to public health due to postprocess contamination by several bacterial pathogens, including Arcobacters. The objective of the study was to evaluate the behavior of Arcobacter butzleri and Arcobacter cryaerophilus in ricotta cheese during its shelf life assuming postprocessing contamination. Two types of ricotta cheese, artisanal water buffalo (WB) and industrial cow milk ricotta cheese, were experimentally contaminated with A. butzleri and A. cryaerophilus and the count was monitored at 2 different temperatures (6°C and 12°C) during shelf life of 5 d for WB cheese and 22 d for industrial ricotta cheese. In WB ricotta cheese the A. butzleri count remained stable during the 5 d of storage at 6°C, whereas a moderate but significant decrease was observed in A. cryaerophilus count. The counts of both species increased when WB ricotta cheese was stored at 12°C. In industrial ricotta cheese stored at 6°C, a significant reduction was observed both in A. butzleri and A. cryaerophilus counts during the 22-d storage period; at 12°C storage, a count increase was observed for both Arcobacter species up to d 14 of storage after which the log cfu/g count resulted constant until d 22 of storage. The ability of A. butzleri and A. cryaerophilus to survive at 6°C and to grow at 12°C in ricotta cheese has significant food safety implications.

    Full Text Available Loggerhead sea turtles can be incidentally captured by artisanal gears but information about the impact of this fishing is inconsistent and scarce. Recent studies have observed that the bycatch, or incidental catch rate, in fishermen surveys is irregular. The aim of this study was to compare direct data (onboard observers concerning the incidental catch of loggerhead sea turtles by the artisanal vessels versus data from fishermen surveys. The study area was the Cabo de Gata-Níjar marine protected area, situated in the western Mediterranean (southeast of the Iberian peninsula. We observed two loggerhead turtles that were incidentally caught in a total of 165 fishing operations. According to fishermen surveys, a total of nine loggerheads were incidentally caught in 861 fishing operations. The differences between the loggerhead sea turtle bycatch reported by fishermen surveys and scientific observations versus random distribution (x2 = 0.3146, P = 0.575, df = 1 were not significant. We conclude that the surveys are useful but that findings should be interpreted with caution.

Given the unavailability of sleep data about Lebanon, the cultural shifts and socioeconomic pressures that have affected many aspects of society, particularly for students and working adults, as well as our understanding of sleep in university students in other countries, we conducted a national study to assess sleep quality and factors contributing to sleep and general health in a culture-specific context. A self-filled questionnaire, inquiring about sociodemographics, health-risk behaviors, personal health, and evaluating sleep quality and chronotype using standard scales was completed by 540 students at private and public universities in Lebanon. Overall, they reported sleeping 7.95±1.34 hours per night, although 12.3% reported sleeping <6.5 hours and more than half scored in the poor-sleeper category on the Pittsburgh Sleep Quality Index (PSQI. Sleep timing differed markedly between weekdays and weekends, with bedtimes and wake-up times delayed by 1.51 and 2.43 hours, respectively, on weekends. While most scored in the "neither type" category on the Morningness–Eveningness Questionnaire (MEQ, 24.5% were evening types and 7.3% were morning types. MEQ score was significantly correlated with smoking behavior and daily study onset, as well as with PSQI score, with eveningness associated with greater number of cigarettes, later study times, and poor sleep. We conclude that the prevalence of poor sleep quality among Lebanese university students is associated

    The Mediterranean--mare nostrum--has always been a cradle of exchanges for the different inhabitants of its shores, as highlighted by myths and legends dating back to antiquity. Cooperation between France and Lebanon expanded markedly in the 17th century and has continually expanded since, in fields such as education, through initiatives launched by the French government and by religious institutions. The Faculty of Medicine is an excellent example. The instigator was the Society of Jesus, which had created St Joseph University in 1875, eventually being supported by the French government. Following an agreement signed on 7 May 1883 between the Society of Jesus and the French authorities, the medical school opened on November 30th of the same year. The school soon became a faculty, and was managed until 1976 by a chancellor who answered to a French academic institution and delivered French state medical degrees. In 1976, however, following changes to the statutes of St Joseph University and the Faculty, the latter became a fully fledged Lebanese Faculty of Medicine delivering its diplomas through St Joseph University. The faculty soon needed a hospital complex to meet its students' medical needs. After some trials with local hospitals, it was decided to build the facility from scratch, and to name it Hotel Dieu de France. Construction was financed by the French government, and by a subscription launched by the French Press Syndicate, at the initiative of the newspaper Le Temps and at the request of the French Asia Committee (Comité de l'Asie Française). The Hospital was inaugurated on May 27, 1923. It soon encompassed a French maternity unit and cancer center, thus constituting the French Hospital Association (Association Hospitalière Française). In 1984, following an agreement between the French government and St Joseph University, Hotel Dieu became the property of the university, and the vice-chancellor became chairman of the board.

    The prevalence of obesity within countries varies by gender, age, lifestyle and socioeconomic factors. Identification of behavioural factors that are associated with obesity within the country's context is critical for the development of effective public health programs which aim to prevent and manage obesity. The objective of this study was to assess age and gender differentials in the prevalence of obesity in Lebanon and examine correlates of obesity with a focus on socioeconomic disparities. Following the WHO STEPwise guidelines, a national survey was conducted in Lebanon in 2008-2009. Households were selected randomly from all Governorates based on stratified cluster sampling method. One adult aged 20 years and over was randomly selected from each household for the interview. Anthropometric measurements and 24 hour recall dietary intake were obtained. The final sample included 1244 men and 1453 women. Descriptive statistics were computed for BMI, waist circumference, and percent body fat. Multivariate logistic regression analysis was carried out to assess the relationship between energy intake and obesity adjusted for relevant co-variables. The prevalence of obesity among Lebanese adults was 26.1%. Gender differences in obesity estimates were observed across age groups and the three obesity classes, with men showing higher prevalence rates at the younger age groups (20-49 years), and women showing higher prevalence rates in older age groups (50 years and above). Obesity showed significant associations with socio-economic status in women; it decreased with higher educational attainment (OR = 0.54, 95% CI: 0.32, 0.91), greater household assets (OR = 0.26; 95% CI: 0.10, 0.72) and lower crowding index (OR = 0.62; 95% CI: 0.39, 0.98), net of the effect of other co-variates. There was a significant positive association between obesity and energy intake in both genders, and a negative association between obesity and physical activity, significantly

    Coastal communities worldwide rely on small-scale artisanal fisheries as a means of increasing food security and alleviating poverty. Even small-scale fishing activities, however, are prone to resource depletion and environmental degradation, which can erode livelihoods in the long run. Thus, there is a pressing need to identify viable and resilient artisanal fisheries, and generate knowledge to support management within the context of a rapidly changing climate. We examined the ecosystem-level consequences of an artisanal kelp fishery (Macrocystis pyrifera), finding small-scale harvest of this highly productive species poses minimal impacts on kelp recovery rates, survival, and biomass dynamics, and abundances of associated commercial and culturally important fish species. These results suggest that small-scale harvest poses minimal trade-offs for the other economic benefits provided by these ecosystems, and their inherent, spiritual, and cultural value to humans. However, we detected a negative impact of warmer seawater temperatures on kelp recovery rates following harvest, indicating that the viability of harvest, even at small scales, may be threatened by future increases in global ocean temperature. This suggests that negative impacts of artisanal fisheries may be more likely to arise in the context of a warming climate, further highlighting the widespread effects of global climate change on coastal fisheries and livelihoods.

    We report 2 patients who had radial keratotomy (RK) to correct myopia. The first patient developed a postoperative hyperopic shift and cataract. Nine years post RK, she had intracapsular cataract extraction and implantation of an Artisan aphakic intraocular lens (IOL). Twenty years post RK, hyperopia and astigmatism progressed to +7.0 -5.75 x 100 with a best corrected visual acuity (BCVA) of 20/20. Due to contact lens intolerance, the Artisan aphakic IOL was exchanged for an Artisan toric aphakic IOL. Three months later, the BCVA was 20/20 with +1.0 -0.50 x 130. The second patient demonstrated residual myopic astigmatism 6 years after bilateral RK and had become contact-lens intolerant. An Artisan toric phakic IOL was implanted in both eyes. Four months later, the BCVA was 20/25 with a refraction of +0.25 -1.0 x 135 and 20/20 with a refraction of -1.0 x 40. Both patients were satisfied with the visual outcomes.

    The Serra da Canastra region, located in southwestern Minas Gerais, Brazil, is recognized worldwide for its tradition of producing artisanal cheeses. However, as production is done by hand, great variability exists in the characteristics of artisanal Minas cheese. Thus, it is important to characterize the sensory profile of these products and verify the quality attributes that lead to their acceptance. Therefore, this study aimed to characterize the dynamic sensorial profile of artisanal Minas cheese produced in the Serra da Canastra region through temporal dominance of sensations and sensory acceptance tests and verify the attributes that lead to product quality. We observed that the texture and flavor profile varied among the evaluated artisanal Minas cheeses from Serra da Canastra, some cheeses being more characterized by creamy and soft or hard and firm sensations, whereas others had high dominance rates for crumbly texture. In relation to flavor, salty and bitter tastes were dominant in most cheeses, some also being characterized by a sour taste, and others by buttery and rancid attributes, which indicates a lack of product standardization. However, all samples obtained scores between 6 (liked slightly) and 7 (liked moderately), indicating good acceptability in relation to the texture and flavor of the evaluated cheeses. Moreover, it is possible to infer that creamy and soft or hard and firm are positive attributes for cheese texture, and bitter, buttery, salty, and acid taste drive cheese acceptance. This study provides important information for product standardization, quality improvement, and process origin indications, besides providing quality attributes that meet consumer desires.

This study aims at examining dietary, lifestyle, and socio-economic correlates of overweight, obesity, and abdominal adiposity amongst children and adolescents in Lebanon, a country of the Eastern Mediterranean basin. A nationally representative cross-sectional survey was conducted on 6–19-year-old subjects (n = 868. Socio-demographic, lifestyle, dietary, and anthropometric data (weight, height, waist circumference were collected. Overweight and obesity were defined based on BMI z-scores. Elevated waist circumference (WC and elevated waist to height ratio (WHtR were used as indices of abdominal obesity. Of the study sample, 34.8% were overweight, 13.2% were obese, 14.0% had elevated WC, and 21.3% had elevated WHtR. Multivariate logistic regression analyses showed that male gender, maternal employment, residence in the capital Beirut, sedentarity, and higher consumption of fast food and sugar sweetened beverages were associated with increased risk of obesity, overweight, and abdominal adiposity, while regular breakfast consumption, higher intakes of milk/dairies and added fats/oils were amongst the factors associated with decreased risk. The study’s findings call for culture-specific intervention strategies for the promotion of physical activity, healthy lifestyle, and dietary practices amongst Lebanese children and adolescents.

    The personal dosimetry service at the Lebanese Atomic Energy Commission uses Harshaw 8814 cards with LiF:Mg,Ti detectors. The dosemeters are read in a Harshaw 6600 TLD reader. In the process of accreditation for the ISO 17025 standard((1)), different influence factors are investigated and the uncertainty has been determined. The Individual Monitoring Service Laboratory-LAEC reads the dosemeters once it receives them from the customer, and new cards are immediately given for the next wearing period. The wearing period is 2 months. The dosemeter results are reported to the customers without background subtraction. Both Hp(10) and Hp(0.07) are reported. For this paper, only the uncertainty on Hp(10) will be focussed. The following factors are taken into account for the uncertainty: calibration factor, dosemeter homogeneity and repeatability, energy and angular dependence, non-linearity, temperature dependence, etc. Also the detection limit was determined. One of the important factors is the correction for fading. This fading correction depends on the procedure used such as storage temperatures, the time-temperature profile of the read-out, pre-heat and annealing conditions. Pre- and post-irradiation fading curves were measured for a storage period up to 182 d at room temperature (15-25°C). The resulting final combined standard uncertainty on the reported doses is of the order of 24 % for doses of ∼1 mSv.

    Full Text Available The purpose of this study was to investigate the bacterial etiology of urinary tract infections in one of the busiest hospitals of Lebanon and to examine the epidemiologic and microbiologic properties of Escherichia coli isolated from urinary tract infections of Lebanese patients over a 10-year period. Methods. This retrospective study analyzed the data generated between 2000 and 2009 (10,013 Gram-positive and Gram-negative bacteria. Bacterial identification was based on standard culture and biochemical characteristics of isolates. Antimicrobial susceptibility was tested by the disk diffusion method, and ESBL production was detected by synergy with third-generation cephalosporins and amoxiclav. Results. E. coli was the most frequent isolate throughout the ten years (60.64% of the total isolates. It was followed by Klebsiella pneumoniae and Proteus sp., Pseudomonas aeruginosa, Enterococcus sp., and Streptococcus agalactiae. E. coli occurred more frequently in women (69.8% than in men (61.4%. The lowest percentage of susceptibility of E. coli was manifested against piperacillin and ampicillin. An increase in the production of ESBL was observed (2.3% in 2000 to 16.8% in 2009. Conclusions. The etiology of urinary tract infections and their susceptibility profiles are important to be evaluated in countries like Lebanon where a severe misuse of antibiotics at all levels is observed.

    The present comparative cross-cultural study aimed to explore the relationship between eating behaviour and sociocultural influences with respect to appearance and body image in female university students from two cultural contexts, namely Cyprus and Lebanon. The Dutch Eating Behavior questionnaire (DEBQ) and the Perceived Sociocultural Influences on Body Image and Body Change Questionnaire were used to assess sociocultural influences and body image, respectively, in 200 students from each country. The results indicated that the Lebanese students were more likely to engage in emotional and external eating and their body image was impacted to a larger extent by sociocultural agents, including media influences, compared to the Cypriot students. Also, a positive relationship was found between emotional and external eating in both cultures. Finally, sociocultural influences correlated positively with external eating only in the Cypriot sample. Culture-specific factors, such as the societal values and norms, as well as the Westernisation history of each country, are discussed as underpinnings for the differences found. These findings are significant for understanding the rise of eating pathology in these two cultures and provide evidence for a need to consider cultural environment when designing public health policies addressing the negative aspects of nutrition transition. © 2013 The Authors Journal of Human Nutrition and Dietetics © 2013 The British Dietetic Association Ltd.

    High-fidelity simulation (HFS) offers a strategy to facilitate cognitive, affective, and psychomotor outcomes and motivate the new generation of students. The purpose of this study was to examine the impact of using high-fidelity simulation on the development of clinical judgment and motivation among Lebanese nursing students. A post-test, quasi-experimental design was used. Two private universities in Lebanon were targeted to implement the intervention. A convenience sample of 56 nursing students from two private universities in Lebanon were recruited. Data were collected using the Lasater Clinical Judgment Rubric and the Motivated Strategies for Learning questionnaires. Nursing students exhibited significant improvement in clinical judgment and motivation due to exposure to HFS. There was a significant difference post HFS between the intervention group and the control group in clinical judgment intervention (t=5.23, pmotivation for academic achievement (t=-6.71, pmotivation (198.6, SD=10.5) in the intervention group than in the control group (161.6, SD=20). The analysis related to differences between the intervention and control groups in motivation and clinical judgment; controlling for previous experience in health care services, the analysis showed no significant difference (Wilk's lambda =0.77, F=1.09, p=0.374). There is a need for nursing educators to implement HFS in nursing curricula, where its integration can bridge the gap between theoretical knowledge and nursing practice and enhance critical thinking and motivation among nursing students.

    Lead concentrations and isotopic composition of sediment samples collected from three sites within the Lebanese coastal zones were measured: at Akkar, Dora and Selaata. Akkar is located far from any direct source of contamination, while Dora and Selaata receive urban and industrial wastes, respectively. Low Pb concentrations (6-16 {mu}g g{sup -1}) were detected in the Akkar sediments, and high concentrations of Pb (70-101 {mu}g g{sup -1}) were detected in the Dora sediments. Measuring stable isotope ratios of Pb makes it possible to identify the principal sources of Pb in the Akkar sediments as Pb emitted from gasoline combustion and Pb originating from natural sources. On the other hand, Pb stable isotopic ratios in Dora sediments indicate that they are more highly influenced by anthropogenic sources. Isotopic Pb ratios in the Selaata deposits, where Pb concentrations range between 5 and 35 {mu}g g{sup -1}, have an exceptional radiogenic signature for marine sediments 1.25 < {sup 206}Pb/{sup 207}Pb < 1.6 and 0.5 < {sup 206}Pb/{sup 208}Pb < 0.67, which shows the impact of the phosphogypsum discharged by Selaata's chemical plant. Isotopic Pb analysis applied to EDTA extracts, to test the mobility of Pb, shows that that this mobility is high (>60%) after 24 h of extraction, and that the extracted Pb is less radiogenic than the residual Pb.

    Disordered eating behaviors are on the rise among youth. The present study investigates psychosocial and weight-related variables as predictors of eating disorders (ED) through disordered eating (DE) dimensions (namely restrained, external, and emotional eating) in Lebanese university students. The sample consisted of 244 undergraduates (143 female) aged from 18 to 31 years (M = 20.06; SD = 1.67). Using path analysis, two statistical models were built separately with restrained and emotional eating as dependent variables, and all possible direct and indirect pathways were tested for mediating effects. The variables tested for were media influence, perfectionism, trait emotional intelligence, and the Big Five dimensions. In the first model, media pressure, self-control, and extraversion predicted eating disorders via emotional eating. In the second model, media pressure and perfectionism predicted eating disorders via restrained eating. Findings from this study provide an understanding of the dynamics between DE, ED, and key personality, emotion-related, and social factors in youth. Lastly, implications and recommendations for future studies are advanced.

    Alcohol, tobacco and other drugs (ATOD) abuse and addiction are serious problems among Lebanese youth. Peer education on ATOD abuse in several settings has been found to be an effective way of prevention. This paper describes a collaborative project which trained 30 young activists to lead awareness campaigns in the Lebanon about ATOD abuse and healthy alternatives for relieving stress. The project was initiated by the Armenian Relief Cross in Lebanon (ARCL), funded by the Oxfam Canadian Fund for Social Development and implemented in collaboration with stakeholders in the Armenian community and Oum El Nour organization. Following training, the activists offered awareness sessions to a total audience of 5200:1250 secondary students, 50 university students, 1050 scouts, 300 working adolescents, 50 policemen and 2500 parents. Workshop objectives were met and awareness campaigns evaluated positively by the activists, parents of young people, ARCL and other stakeholders: leaders of Armenian institutions dealing with adolescents and the mayor of Bourj Hammoud. Resource constraints precluded seeking feedback from the young people who participated. Collaboration was deemed to have enhanced the capacity of ARCL, Oum El Nour, and the stakeholders in training young trainees to offer awareness campaigns. The author recommends continuing the project; offering another workshop to support the trainees and building in ways to evaluate the impact of the awareness campaigns on knowledge, attitude and behaviors of the young people taking part. To this effect, evaluation of the impact of the awareness campaigns is already started among school students with the use of control/comparison group design.

    Full Text Available Basic raw materials belong to the key input sources in the production of pig iron. The properties of basic raw materials can be evaluated using a variety of criteria. The essential ones include the physical and chemical properties. Current competitive pressures, however, force the producers of iron more and more often to include cost and logistic criteria into the decision-making process. In this area, however, they are facing a problem of how to convert a variety of vastly different parameters into one evaluation indicator in order to compare the available raw materials. This article deals with the analysis of a model created to evaluate the basic raw materials, which was designed as part of the research.

    Basic raw materials belong to the key input sources in the production of pig iron. The properties of basic raw materials can be evaluated using a variety of criteria. The essential ones include the physical and chemical properties. Current competitive pressures, however, force the producers of iron more and more often to include cost and logistic criteria into the decision-making process. In this area, however, they are facing a problem of how to convert a variety of vastly differ...

    Artisanal gold mining is the main economic activity in the Yani district, Northern Bolivia. In this area abundant orogenic gold deposits constituted by quartz veins hosted in paleozoic turbiditic series that contain either free gold or associated with pyrite. Gold is recovered in processing plants by gravimetric methods using shaking tables in several communities of this district. Previously, miners ground the mineral in ball mills together with mercury. The present study aims to evaluate the effect of mercury used in the gold recovering process to the environment and human health in the Yani district. The assessment was based on the analysis of human hair, sediments and water from the river nearby the processing plant and drinking water from the fountain that supplies these communities. 47 samples of hair from miners and other people from the Yani and Señor de Mayo communities were obtained in 2014 and 52 samples in 2015. All were analysed to evaluate the mercury exposure in these places. The results from the 2014 sampling show a wide range of Hg concentration in hair, especially in Señor de Mayo, with values up to 136 μg/g THg. However, in 2015 among the 43 residents in Señor de Mayo, 29 (67%) exhibit concentrations higher than 2 μg/g THg, with an average value of 5.36 μg/g THg. On the other hand, in Yani only 40% have concentrations above 2 μg/g THg, with an average value of 2.34 μg/g THg. The content in Hg in most of the hair samples exhibit values above the tolerable limits established by the US Environmental Protection Agency (1 μg/g Hg) and the World Health Organisation (WHO, 2 μg/g Hg). These high Hg concentrations are found not only in miners but also in the other members of the community, in spite of low fish consumption in this area. Part of the hair was analysed before and after cleaning. Usually in the second case the content of Hg is reduced, but still show high Hg levels, then probably the atmosphere is polluted with Hg and population is

    Full Text Available Quality of life is an indicator of how well one perceives that he/she is functioning physically and mentally. The aim of this paper is to determine the health-related quality of life (HRQOL of artisanal fisherwomen/shellfish gatherers from the Saubara municipality in Bahia, Brazil in comparison to the general population. A structured questionnaire was administered to a sample of 209 artisanal fisherwomen selected at random. The HRQOL questionnaire, known as the 36-Item Short-Form Health Survey version 1 (SF-36v01, was also used, having been translated and verified cross-culturally for the Brazilian population. Sociodemographic, lifestyle and comorbidity information was also collected. Chronic diseases and indicators of musculoskeletal disorders (MSDs were self-reported. The study population consisted primarily of individuals between 30 and 45 years of age (78%, of self-classified races black or brown (96.2%, with no more than an elementary school education (77% and married (64.6%. In all the SF-36v01 dimensions, the values in the sample were lower than in the general population of Brazil, which was used as the reference population. In the “Physical Health” domain (Physical Functioning; Physical Role Limitations; Bodily Pain; General Health Perception a tendency toward a lower health-related quality of life was observed among those who were older, had a lower education level, and had a prevalence of MSDs, hypertension or arthritis. The interference of health conditions linked to the fisherwomen’s work activities may contribute to lower HRQOL in all analyzed aspects, in comparison to the general population. In light of these findings, public health policies must consider these informal workers who contribute greatly to Brazil’s economy and food system.

    Full Text Available The purpose of this study was to characterize factors affecting lactose quantities in raw cow's milk. This study combined the survey design with laboratory analysis. Selected farm members of Nong Poh Dairy Cooperatives, from Ban Pong and Photharam Districts, Ratchaburi Province, were sampled. From the selected farms, data collected included lactose quantities in the raw milk and dairy farming information. The raw milk of selected farms was sampled at the delivery site of Nong Poh dairy cooperatives in the morning during December 2003 till February 2004. Lactose in the raw milk was then quantified by the Fourier Transform Infrared Analysis (FTIR using the MilkoScan FT6000 at the Department of Livestock Development. The farm owners or managers of selected farms were in-depth interviewed on dairy farming information including cowsí health and cows' diet. The data revealed that all cows from the selected farms were fed with concentrate diet purchased from Nong Poh Dairy Cooperatives and grass as high fiber diets. Sample of eighteen farms also fed their cows with one of supplements: corn stem, soybean meal, or rice straw. All cows from these farms were Holstein-Friesian Hybrid. As supplemented high fiber diets, corn stem significantly increased the lactose quantities over soybean meal and rice straw (planned comparison, pvalue = 0.044. The study concluded that some high fiber diets, specifically corn stem, significantly contributed to the lactose quantities in raw milk.

    In Ukraine 13 VVER-1000 and 2 VVER-440 reactor units generate about 50 % of the country's energy production. By contrast, when looking at the large volume of radioactive waste of all categories, which is produced by these nuclear power plants (NPP), the radioactive waste (RAW) management - onsite of NPP, towards interim storage as well as towards final disposal - is still not adequately developed. Currently all operational waste of Ukrainian NPP is incompletely treated/conditioned and stored onsite, though insufficient storage capacity is available at the NPP. As no effective Ukraine-wide strategy is yet established to manage RAW beyond NPP a serious situation could arise, which even leads to constrained temporary shut-down of reactor units, threatening the energy supply of whole the country. In addition large quantities of RAW, partly badly sorted, derive from decommissioning of the shut-down Chernobyl NPP. Also other sources of RAW contribute to the whole volume, which has to be managed in Ukraine, as research reactors, reprocessing of spent nuclear fuel and other nuclear facilities and applications. Nevertheless, operational and shut-down NPP in Ukraine are by far the largest producers. To support Ukraine in managing their radioactive waste NUKEM Technologies GmbH was appointed to provide technical support for the improvement of the current situation in cooperation with responsible Ukrainian experts towards a targeted, comprehensive and effective RAW management.

    Organic amendments, green manure and plant residues incorporation are the main sources of nutrients in organic farming, their decomposition rate is crucial for the accumulation and long-term storage of organic matter in soils. In this study the decomposition of compost from olive mill waste (N: 29.3 g kg-1; total dissolved nitrogen or TDN: 3.82 g kg-1), goat manure (N: 31.5 g kg-1; TDN: 0.94 g kg-1), the shoots (N: 33.6 g kg-1; TDN: 17.57 g kg-1) and roots (N: 22.12 g kg-1; TDN: 8.87 g kg-1) of Medicago sativa was followed in three Lebanese soils. The nitrogen, phosphorus and potassium released were followed over one year, starting in early winter (December-January). The mild sub-humid Mediterranean conditions allowed a rapid mass loss in alfalfa shoots 30 days after incorporation. Manure and compost were more persistent. Between 80 and 90% of TDN were released, after 30 days of in-situ incubation for compost, the release was over 90% for alfalfa shoots. The movement of P was slower, as the compost (6.99 g kg-1 of P) and manure (9.81 g kg-1 of P) lost 33% and 22%, respectively, during 30 days of incubation. After one year, 15 to 35% of P remained in the soils. The manure was the richest in potassium (19.66 g kg-1) followed by the alfalfa shoots (15.56 g kg-1), the compost (8.19 g kg-1) and the roots (5.96 g kg-1). The loss of potassium was important, as over 88% had disappeared over the year. All decomposition curves followed an exponential model. The calculated coefficients of decomposition for total nitrogen (lnfinal - lninitial/days) were significantly higher for alfalfa shoots (0.00547 day-1) and similar for the compost (0.00184 day-1) and the manure (0.00175 day-1). The ANOVA test showed a difference between two of the sites (Site A: 521 g kg-1 of clay and 42 g kg-1 of calcium carbonate; Site S: 260 g kg-1 of clay and 269 g kg-1 of CaCO3) and the third one (Site L: 315 g kg-1 of clay and 591 g kg-1 of CaCO3).

    Full Text Available Canastra cheese is one of the oldest and most traditional cheeses made from raw milk in Brazil. However, this type of practice may have severe consequences for human health. According to the current legislation, any cheese made from raw milk must be aged for at least 60 days. Traditionally, Canastra cheese is consumed after different ripening periods, but consumers usually prefer those that are aged less than eight days. This study aimed to evaluate the effects of physicochemical and microbiological parameters, with emphasis on the pathogenic microbiota regulated by law, on cheese aged at room temperature and under refrigeration. Cheese samples were collected from eight different cheese producers located in the Serra da Canastra region twice a year (rainy and dry seasons and analyzed with 8, 15, 22, 29, 36, and 64 days of ripening. Room temperature aging effectively reduced pathogens, reaching the total count established by law in 22 days, regardless of the season. However, ripening under refrigeration, it was ineffective in reducing the Staphylococcus aureus counts to the legislation limits, even after 64 days. Therefore, Canastra cheese should be ripened for at least 22 days at room temperature in order to fulfill the safety regulatory limits.

    Water buffalo mozzarella cheese (WBMC) is a fresh stretched cheese produced from whole chilled buffalo milk. Although pasteurization of milk and the use of defined starter cultures are recommended, traditional technology involving unpasteurized milk and natural whey cultures is still employed for WBMC production in Italy. The purpose of this study was to assess the behavior of Arcobacter butzleri during WBMC production and storage under different temperature conditions (5, 10, and 20 °C). Raw milk was experimentally inoculated with one reference strain and two isolates of A. butzleri, and the count was monitored during WBMC production and storage. The bacterial count of A. butzleri decreased during curd ripening (from 7.83 log colony-forming units (CFU)/g to 4.14 log CFU/g in about 4 h) and a further decrease (>4 log CFU/g) was observed at the end of curd stretching. During storage testing, A. butzleri was never detected by direct plating, whereas it was recovered from 12 of the total 162 WBMC until the end of storage testing by enrichment. The results revealed that A. butzleri is able to survive during WBMC production and storage at different temperature conditions. Consequently, traditional WBMC produced from raw milk could represent a potential source of Arcobacter infection for humans.

    Full Text Available The early treatment of urinary tract infections is directly related to decrease in morbidity, which makes the empirical treatment of great importance. Recently, beta lactamases of several types have emerged as significant mechanisms of resistance in Gram negative bacilli, especially Escherichia coli. Our aim was to study the urinary E.coli isolated from Lebanese patients and to characterize their mechanisms of resistance. The study analyzed data between 2005 and 2012 of urinary tract infections caused by E.coli. The mechanisms of resistance were characterized by phenotypic and genotypic methods and the Pulsed Field Gel Electrophoresis was used to determine the different bacterial clusters. As expected, the highest incidence was observed with E. coli (60.53 to 73.98% followed by K pneumoniae (5.32 to 8.33%. ICU isolates were constantly associated with the lowest rates of susceptibility to extended spectrum cephalosporins, ciprofloxacin, as well as most of the tested antibiotics. A 100% occurrence of CTX-M in ESBL producing isolates was recorded, followed by TEM, SHV, and OXA. In addition, 15.9% harbored 4 different ESBL enzymes and only 13 isolates (14.8% harbored only one enzyme (CTX-M. Over the years, the simultaneous susceptibility of E. coli to ceftazidime and ciprofloxacin decreased from 62.5% in 2006 to 48.7% in 2012. PFGE results demonstrated that 10 clusters were 32 generated, denoting diversity among detected isolates. Understanding the epidemiology of resistance is 33 instrumental for the implementation of recommendations for the management of antimicrobials, infection 34 control measures, as well as active surveillance and antimicrobial stewardship.

Between December 2012 and January 2014, 67 individuals were collected by bottom longlining in coastal Lebanese marine waters at different ports at depths ranging from 10 to 110 m. The total length (L(T)) of the specimens ranged from 50 to 143 cm, and the mean ± s.d. was 76.2 ± 19.7 cm. The most common L(T) classes were between 60 and 70 cm. The total mass of the specimens ranged from 410 to 10,000 g, and the mean ± s.d. was 1841 ± 1987 g. A total of 34 males and 33 females were collected, and the sex ratio was not significantly different from 1:1. The mass and L(T) relationship showed positive allometric growth (b = 3.096 and r(2)  = 0.99), and the mean ± s.d. L(T) at which 50% of the individuals were sexually mature was 84.73 ± 5.81 cm for females and 78.57 ± 4.88 cm for males. The gonado-somatic and hepato-somatic indices were determined along with a condition factor, and parturition appeared to occur in winter. The primary prey items found in the fish stomachs during the autumn and winter seasons were Penaeidae. The results of this study will help to parameterize models of the population dynamics for this exploited fish stock to ensure the long-term sustainability of its fishery.

    Full Text Available The first part of this review article considers general data about ethanol as an industrial product, its qualities and uses. It is emphasized that, if produced from biomass as a renewable raw material, its perspectives as a chemical raw material and energent are brilliant. Starchy grains, such as corn, must be used as the main raw materials for ethanol production. The production of bioethanol by the enzyme-catalyzed conversion of starch followed by (yeast fermentation, distillation is the process of choice. If used as a motor fuel, anhydrous ethanol can be directly blended with gasoline or converted into an oxygenator such as ETBE. Finally, bioethanol production in Yugoslavia and the possibilities for its further development are discussed.

    The objective of this study was to evaluate whether nicotine dependence was higher in Lebanese women smokers compared with men smokers. Data were taken from a national cross-sectional study. Lebanese residents aged ≥ 40 years were enrolled between October 2009 and September 2010. After informed consent, participants answered a standardized questionnaire about smoking behaviors and dependence (measured by the Fagerström-Test-Nicotine-Dependence for cigarettes and the Lebanon-Waterpipe-Dependence-Scale 11 for waterpipes): 1,066 males and 1,134 females were interviewed. 58.7% versus 42.9% of them, respectively, ever smoked cigarettes, while 6.9% versus 6.7% ever smoked a waterpipe (p waterpipe smokers (p = 0.076), and 67.9% versus 43.6% in mixed smokers were tobacco dependent. A dose-effect relationship was observed with increased rates of women versus men with waterpipe dependence) and an increased odds of dependence among women in multivariable analysis (ORa = 2.28). Positive (smoking waterpipe for pleasure and conviviality) and negative (smoking waterpipe to relax nerves and improve morale) reinforcements were significantly more frequent in women, while no significant sex difference was observed for nicotine dependence or psychological craving. In exclusive waterpipe smokers, significantly higher respiratory diseases and symptoms prevalences were found in females compared with males.

    Full Text Available The supply chain is a major issue in a global market. The efficient relationship between supplier-producer-retailer conforms the perfect combination to achieve a high level of competitiveness according to the needs of increasingly demanding and changing markets. The difficulty of synchronizing the members within the SC is related to the inherent uncertain factors. This paper proposes a methodology for integrating the supply chain that can be applied in any type of business. To demonstrate its relevance, a case study is performed at a handmade shoe company. An improved demand forecasting, an optimal balanced production line, a proper inventory management of raw materials, and an efficient calculation of the delivery time to the customer represent some of the main results.

    There is an urgent need to quantify the impacts of artisanal fisheries and define management practices that allow for the recovery and conservation of exploited stocks. The extent of illegal catch is particularly critical as a driver of overexploitation in artisanal fisheries. However, the lack of data at proper spatial scales limits the evaluation of illegal fishing and effectiveness of management practices. We used a catch curve analysis to estimate total instantaneous mortality as a proxy of fishing pressure in the artisanal benthic fishery in central Chile. We compared the patterns of total mortality in fishing grounds under the well-studied territorial use rights for fisheries system (TURF) immersed in a landscape of open access areas (OAA; no access restriction), and from these patterns determined the extent of illegal fishing in open access areas focusing on the two most frequently extracted resources: locos (Concholepas concholepas) and keyhole limpets (Fissurella spp.). The beauty of this seascape is the presence of the no-take (NT) area of Las Cruces as control (no fishing), allowing us to estimate natural mortality. Loco exploitation is banned in OAAs. However, loco mortality in OAAs was 92% higher than in the NT, and 42% higher than in TURFs. Keyhole limpet mortality was similar between TURFs and the NT, but doubled in OAAs. We also found strong differences in mortality among fishing grounds with the same level of protection (i.e. TURFs), and over time. Our results highlight (a) the high level of illegal fishing that may occur in artisanal fisheries under traditional management regimes, and (b) that TURFs can be effective to reduce fishing mortality. However, large variability among TURFs suggests the need for a deeper understanding of the drivers of success of TURFs.

    2011-06-01

    We present a low-complexity method for compression of raw Synthetic Aperture Radar (SAR) data. Raw SAR data is typically acquired using a satellite or airborne platform without sufficient computational capabilities to process the data and generate a SAR image on-board. Hence, the raw data needs to be compressed and transmitted to the ground station, where SAR image formation can be carried out. To perform low-complexity compression, our method uses 1-dimensional transforms, followed by quantization and entropy coding. In contrast to previous approaches, which send uncompressed or Huffman-coded bits, we achieve more efficient entropy coding using an arithmetic coder that responds to a continuously updated probability distribution. We present experimental results on compression of raw Ku-SAR data. In those we evaluate the effect of the length of the transform on compression performance and demonstrate the advantages of the proposed framework over a state-of-the-art low complexity scheme called Block Adaptive Quantization (BAQ).

    2011-05-01

    The results of heavy element profiling of the gold ores and sediments associated with the artisanal gold mining activities of the Migori gold belt of Southwestern Nyanza, Kenya, were reported in this paper. The analysis was made to assess the occupational exposure of the miners as well as to investigate the environmental impact of toxic heavy metals. Gold ores and sediments from the artisanal gold processing were sampled in four artisanal gold mining areas: Osiri A, Osiri B, Mikei and Macalder (Makalda) and analyzed for heavy elemental content using (109)Cd radioisotope excited EDXRF spectrometry technique. Analysis consisted of direct irradiating of sample pellets. The concentrations of major elements detected were: titanium (711.41-10,766.67 mg/kg); cobalt (82.65-1,010.00 mg/kg); zinc (29.90-63,210 mg/kg); arsenic (29.30-8,246.59 mg/kg); gold (14.07-73.48 mg/kg); lead (16.31-14,999.40 mg/kg) and mercury (16.10-149.93 mg/kg). The average concentration of the heavy toxic metals i.e. arsenic, lead, titanium and zinc were found to be above 50 mg/Kg as recommended by World Health Organization.

    Contraceptive uptake in Ghana, especially in the Ashanti region remains low. This may be partly due to products' characteristics and choice which are influenced by attribute utility trade-offs by consumers in determining which method offers the optimal combinations, given the needs and desires of the individuals making the choice. The study sought to determine how specific attributes of contraceptives influence artisanal auto mechanics' stated preferences for a hypothetical contraceptive use in the Tafo-Suame industrial area of Kumasi, Ghana. A discrete choice experiment was conducted with artisanal auto mechanics in the study area from May to September 2011. Based on the summary of the attributes from the focus group discussion and in-depth interviews preceded administration of structured questionnaire, a discrete choice experiment (DCE) was created. The attributes used were; side effects, reversibility, ease of use, ability to prevent both pregnancy and sexually transmitted infection (STI's), price and privacy in acquiring and attractiveness of the method. A total of 340 consented respondents aged 15 to 49 years participated in the study. Data were entered in Access and Sawtooth software SSI Web CAPi module and then exported to Stata for analysis. The study showed a universal (99.4%) knowledge on contraception, ever used 87% and currently using a method, 58%. The study revealed that methods' reversibility (β = 21.74; 95% CI: 20.17, 23.3), minimal allergic reaction (β = 13.93; 95% CI: 12.8, 15.05) and no effect on blood pressure (β = 12.71; 95% CI: 11.62, 13.79), were strongly associated with contraceptive preference and use. While contraceptives' ability to prevent "only pregnancy", (β = -15.13: 95% CI: -16.2, -14.02; "only STI's") (β = -11.65; 95% CI: -11.84, -11.46); and interrupt during sexual activity (β = -4.26; 95% CI: -5.19, -3.34), had large negative influence on contraceptive preference and use.

    Full Text Available This research was carried out to evaluate the influence of seasonal variation in physicochemical composition and microbiological profile of buffalo milk and of the artisanal cream and butter types cheeses produced on Marajó Island. Eighteen farms located of the island were involved in the study. Milk and cheese quality were evaluated in two typical seasons. The rainy, from January to June and dry, from July to December. Samples were submitted to a detailed set of laboratorial analyses. Physicochemical composition of buffalo milk was influenced by the seasons. Compared to rainy, the dry period showed an increase in fat (5.53±0.71 to 6.74±1.19 and lactose (4.77±0.20 to 5.20±0.20 concentrations and reduction in total solids (16.89±0.92 to 15.77±1.54, nonfat dry matter (9.94±0.36 to 8.99±1.23 and minerals (0.84±0.12 to 0.62±0.09 concentrations (p<0.05. The season influence was observed in physicochemical composition of both cheese-types. Compared to rainy season, in the cream cheese type, higher values (p<0.05 were found for titratable acidity (0.63±0.02 to 0.78±0.15, fat (32.38±3.22 to 36.89±4.59, fat in the dry matter (55.06±3.26 to 63.92±2.49 but lower values for water activity (0.99±0.02 to 0.49±0.03, minerals (2.37±0.55 to 1.40±0.02 and calcium (0.28±0.08 to 0.18±0.07. For the butter cheese type, in the dry season, higher values were found only for titratable acidity (0.49±0.02 to 0.38±0.0 and lower values for water activity (0.18±0.07 to 0.45±0.08. The study have shown that some components of the buffalo milk and artisanal cheeses produced on Marajó Island are influenced by the dry and rainy typical seasons and therefore, some sensory variations are expected around the year.

    The study concerns the impact of the atmospheric pollution of automobile origin in the drivers population. It includes two parts:the first part is an inquiry to 188 Parisian artisans taxi drivers, with a questionnaire. The objective is to determine the behavior about this phenomenon and what perception they have of it. The second part is an exposure study that consists in four pollutants (carbon monoxide, fine particulates in suspension, nitrogen monoxide and nitrogen dioxide). It is in order to reveal the concentrations of these pollutants inside 29 cabs during the professional activity. The taxi drivers complain of headaches, eyes and throat irritations, respiratory difficulties. The results of exposure measurements show 3.8 p.p.m. for carbon monoxide, 168 micrograms/m{sup 3} for the fine particulates in suspension, 625 micrograms for nitrogen monoxide and 139 micrograms/m{sup 3} for nitrogen dioxide. These measures are clearly higher than these ones measured in Parisian ambient air, even higher than these ones of stations that are exposed to the maximum level to automobile effluents. (N.C.)

    Full Text Available In this study two raw cow's milk cheeses of a different ripening period were examined. The cheeses were taken from a country household in the region of mountain Stara Planina and manufactured without adding of starter culture. A total 106 lactic acid bacteria (LAB strains were isolated from both cheeses. They are tested by classical physiological tests as well as by API 50 CH tests. Proteolytic and antimicrobial activities were done too. Identification of LAB isolates was done by repetitive extragenic palindromic-polimerase chain reaction (rep-PCR with (GTG5 primer. The LAB isolates from cheese BGPT9 (four days old belonged to the eight species of LAB (Lactobacillus plantarum, Lactobacillus paracasei subsp. paracasei, Lactobacillus delbrueckii, Lactobacillus brevis, Enterococcus faecium, Enterococcus faecalis, Enterococcus durans and Leuconostoc garlicum, while in the BGPT10 cheese (eight months old only two species were present (Lactobacillus plantarum and Enterococcus faecium. Proteolytic activity showed 30 LAB from BGPT9 cheese, mainly enterococci. From BGPT10 cheese only one isolate (which belonged to the Lactobacillus plantarum species possessed partial ability to hydrolyze β-casein. Seven enterococci from BGPT9 cheese and four enterococci from BGPT10 cheese produced antimicrobial compounds.

    2011-01-01

    Many reviews have discussed Salmonella in poultry and suggested best practices to minimize this organism on raw poultry meat. Despite years of research and conscientious control efforts by industry and regulatory agencies, human salmonellosis rates have declined only modestly and Salmonella is still found on raw poultry. Expert committees have repeatedly emphasized the importance of controlling risk, but information about Salmonella in poultry is often limited to prevalence, with inadequate information about testing methods or strains of Salmonella that are detected by these methods and no information about any impact on the degree of risk. This review examines some assumptions behind the discussion of Salmonella in poultry: the relationships between sampling and cultural methodology, prevalence and numbers of cells, and the implications of serotype and subtype issues. Minimizing Salmonella contamination of poultry is not likely to reduce human salmonellosis acquired from exposure to contaminated chicken until these issues are confronted more systematically.

    Full Text Available This paper deals with raw material problems in the territory of West Central Serbia geologically determined as the Čačak-Kraljevo (or West Morava basin. Our research is presented through the most striking case studies, Lojanik, Vlaška Glava and Lazac.  The Lojanik hill is a silicified forest by origin. It has occasionally been in use from the earliest periods of prehistory until today as a source of black and ochre-coloured flint, opal and silicified wood. A detailed prospection, including the mapping of surface finds using square nets, was conducted during two research campaigns.The Vlaška Glava is an open-air Palaeolithic site at which artefacts made of white, ochre, red, brown and black chert, silicified magnesite, volcanic and metamorphic rocks were found. Our research of primary and secondary geological deposits in the vicinity of the site showed equivalent raw material. We also found an interesting primary deposit of high quality bluish grey flint with outcrop activities (Workshop 1.The Lazac shaft is a contemporary magnesite mine, recently abandoned because of the high percentage of silicon-dioxide. We determined the same raw material in collections found at nearby Neolithic sites. Certain similarities between the wooden support systems of ore exploration in the Middle Ages and modern times were established at the entrance of the shaft.Our research in the territory of the West Morava basin resulted in reconstruction of some links between geological deposits and settlements and also creation of a relevant base for future raw material studies.

    Full Text Available Milk production in Thailand has gradually increased since 1961. Occasional oversupply of raw milk has become one of dairy farmers' major problems. Increasing the consumption of milk by making use of its separated nutrients may offer a solution. This study was to assess the composition of raw milk produced in Thailand, which included fat, protein, lactose, solid-not-fat (SNF and total solid (TS. A large dairy cooperatives in Saraburi Province was selected for the study. About 9% of its total members, constituting 108 farms, were randomly chosen. They consisted of small size (less than 20 cows/farm, medium size (21-100 cows/farm and large size (>100 cows/farm. The majority was medium-size. Raw milk from each farm was sampled at the delivery site of the cooperatives in the morning. Milk data of the 108 farms were compiled at 3 different periods between February and July 2003. The raw milk was analyzed by the Fourier Transform Infrared Analysis (FTIR using MilkoScan FT6000. The results showed the average fat content of 3.50±0.47%, protein of 3.13±0.16%, lactose of 4.59±0.12%, SNF of 8.42±0.20%, and TS of 11.92±0.54%. The samples were superior in all of the nutrients as compared to the standard levels set by the Department of Livestock Development, except for TS. This indicates the possibility of a local production of milk nutrients such as lactose and protein as ingredients for the pharmaceutical and health food industries.

    2009-09-01

    An increasing number of people are consuming raw unpasteurized milk. Enhanced nutritional qualities, taste, and health benefits have all been advocated as reasons for increased interest in raw milk consumption. However, science-based data to substantiate these claims are limited. People continue to consume raw milk even though numerous epidemiological studies have shown clearly that raw milk can be contaminated by a variety of pathogens, some of which are associated with human illness and disease. Several documented milkborne disease outbreaks occurred from 2000-2008 and were traced back to consumption of raw unpasteurized milk. Numerous people were found to have infections, some were hospitalized, and a few died. In the majority of these outbreaks, the organism associated with the milkborne outbreak was isolated from the implicated product(s) or from subsequent products made at the suspected dairy or source. In contrast, fewer milkborne disease outbreaks were associated with consumption of pasteurized milk during this same time period. Twenty nine states allow the sale of raw milk by some means. Direct purchase, cow-share or leasing programs, and the sale of raw milk as pet food have been used as means for consumers to obtain raw milk. Where raw milk is offered for sale, strategies to reduce risks associated with raw milk and products made from raw milk are needed. Developing uniform regulations including microbial standards for raw milk to be sold for human consumption, labeling of raw milk, improving sanitation during milking, and enhancing and targeting educational efforts are potential approaches to this issue. Development of pre- and postharvest control measures to effectively reduce contamination is critical to the control of pathogens in raw milk. One sure way to prevent raw milk-associated foodborne illness is for consumers to refrain from drinking raw milk and from consuming dairy products manufactured using raw milk.

    Colombia is one of the largest per capita mercury polluters in the world as a consequence of its artisanal gold mining activities. The severity of this problem in terms of potential health effects was evaluated by means of a probabilistic risk assessment carried out in the twelve departments (or provinces) in Colombia with the largest gold production. The two exposure pathways included in the risk assessment were inhalation of elemental Hg vapors and ingestion of fish contaminated with methyl mercury. Exposure parameters for the adult population (especially rates of fish consumption) were obtained from nation-wide surveys and concentrations of Hg in air and of methyl-mercury in fish were gathered from previous scientific studies. Fish consumption varied between departments and ranged from 0 to 0.3 kg d(-1). Average concentrations of total mercury in fish (70 data) ranged from 0.026 to 3.3 μg g(-1). A total of 550 individual measurements of Hg in workshop air (ranging from Colombia.

    Full Text Available The drying behaviour of dry-fermented sausage Petrovská klobása ripened in traditional and industrial conditions has been studied. Obtained results indicated that sausages dried in industrial room (batch I had higher weight loss and lower water activity (aw values than counterparts from traditional/artisanal production (batch T. Difference in drying intensity between internal and external fractions of sausages was much more marked for batch I. The experimental data of water content in Petrovská klobása, dried in respective conditions, were compared with values predicted by seven different mathematical models. Comparing the coefficient of determination (r2, root mean square error (ERMS and the reduced chi-square (χ2 values of all equations, it was concluded that the Page mathematical model satisfactorily represents drying characteristics of Petrovská klobása both in traditional (0.990; 2.22 x 10-2 and 6.01 x 10-4, respectively and industrial conditions (0.995; 1.79 x 10-2; 3.91 x 10-4, respectively.

    Full Text Available This paper is one of three synthesis documents produced via an integrated assessment (IA that aims to increase understanding of artisanal and small-scale gold mining (ASGM in Ghana. Given the complexities surrounding ASGM, an integrated assessment (IA framework was utilized to analyze socio-economic, health, and environmental data, and co-develop evidence-based responses with stakeholders. This paper focuses on the causes, status, trends, and consequences of ecological issues related to ASGM activity in Ghana. It reviews dozens of studies and thousands of samples to document evidence of heavy metals contamination in ecological media across Ghana. Soil and water mercury concentrations were generally lower than guideline values, but sediment mercury concentrations surpassed guideline values in 64% of samples. Arsenic, cadmium, and lead exceeded guideline values in 67%, 17%, and 24% of water samples, respectively. Other water quality parameters near ASGM sites show impairment, with some samples exceeding guidelines for acidity, turbidity, and nitrates. Additional ASGM-related stressors on environmental quality and ecosystem services include deforestation, land degradation, biodiversity loss, legacy contamination, and potential linkages to climate change. Though more research is needed to further elucidate the long-term impacts of ASGM on the environment, the plausible consequences of ecological damages should guide policies and actions to address the unique challenges posed by ASGM.

    Full Text Available This study aimed to evaluate the presence of enterotoxigenic S. aureus in the endogenous starter and in Artisan Minas cheeses from the Serra da Canastra. Sixteen samples of endogenous starters and cheese were collected during the rainy and dry seasons. The isolation and enumeration of S. aureus were performed using the PetrifilmTM-Rapid S. aureus Plate Count method. The presence of enterotoxin in the cheese samples was analyzed by the Optimal Sensitivity Plate (OSP method and the ELFA-VIDAS®-Staph enterotoxin-II assay. S. aureus strains were tested for their ability to produce enterotoxins using the Optimal Sensitivity Plate (OSP method and the polymerase chain reaction (PCR assay for the classical enterotoxin genes. The Optimal Sensitivity Plate (OSP method data showed that staphylococcal enterotoxin A (SEA was detected in 75% of the cheese samples, but no toxin was detected with the ELFA-VIDAS method. It was found that 12.5% of the isolated strains produced staphylococcal enterotoxin A (SEA and staphylococcal enterotoxin C (SEC. When using the the polymerase chain reaction (PCR assay, only one isolate was found to harbor an enterotoxin gene, contrary our expectations. However, discrepancies between the immunological and molecular assays are not uncommon. Despite the fact that most isolates did not produce classical enterotoxins, high S. aureus counts in the cheese samples causes concern since there is a risk of the presence of non-classical enterotoxins.

    Full Text Available This study focuses on the small-scale artisanal fishery that captures blue marlins Makaira nigricans in Cote dIvoire. The sizes weights and quantities landed of this species were approached according to the marine seasons and fishing areas. These fishermen mostly Ghanaians use canoes 12 to 17 m as craft and drifting gillnets 4800 to 5400 m to catch fish. The choice of fishing area depends on the direction of the current. When the current flows westward fishing takes place in the east and vice versa. These choices have the advantage that at the return the driving force is developed in the direction of the current. In either case the net is arranged perpendicularly to the direction of the current to act as a filtering barrier. In the absence of marine current the net is arranged perpendicularly to the north-south axis. The Man-Whitney test applied to maturity states following seasons and fishing areas showed a significant difference P 0.05. Sector A2 offshore waters in front of Abidjan Grand Bassam and Jacqueville would be conducive to the capture of mature individuals during warm seas. On the other hand during upwelling fishing should be favorable to sector B offshore waters in front of Grand-Lahou and Fresco where adult marlins are accessible. Capturing M. nigricans on the continental shelf should be discouraged as recruits abound in this area to feed and shelter from large offshore predators.

    Full Text Available This report is one of three synthesis documents produced via an integrated assessment (IA that aims to increase understanding of artisanal and small-scale gold mining (ASGM in Ghana. Given the complexities surrounding ASGM, an IA framework was utilized to analyze economic, social, health, and environmental data, and co-develop evidence-based responses with pertinent stakeholders. The current analysis focuses on the health of ASGM miners and community members, and synthesizes extant data from the literature as well as co-authors’ recent findings regarding the causes, status, trends, and consequences of ASGM in Ghana. The results provide evidence from across multiple Ghanaian ASGM sites that document relatively high exposures to mercury and other heavy metals, occupational injuries and noise exposure. The work also reviews limited data on psychosocial health, nutrition, cardiovascular and respiratory health, sexual health, and water and sanitation. Taken together, the findings provide a thorough overview of human health issues in Ghanaian ASGM communities. Though more research is needed to further elucidate the relationships between ASGM and health outcomes, the existing research on plausible health consequences of ASGM should guide policies and actions to better address the unique challenges of ASGM in Ghana and potentially elsewhere.

    Full Text Available The aim of this work was to isolate and to characterize strains of lactic acid bacteria (LAB with bacteriocin-like inhibitory activity from 27 traditional cheeses artisanal-produced obtained from different Peruvian regions. Twenty Gram+ and catalasenegative strains among 2,277 isolates exhibited bacteriocin-like inhibitory activity against Listeria monocytogenes CWBIB2232 as target strain. No change in inhibitory activity was observed after organic acid neutralization and treatment with catalase of the cell-free supernatant (CFS. The proteinic nature of the antimicrobial activity was confirmed for the twenty LAB strains by proteolytic digestion of the CFS. Two strains, CWBI-B1431 and CWBI-B1430, with the best antimicrobial activity were selected for further researches. These strains were taxonomically identified by phenotypic and genotypic analyses as Enterococcus mundtii (CWBI-B1431 and Enterococcus faecium (CWBI-B1430. The two strains were sensitive to vancomycin (MIC 2 μg.ml-1 and showed absence of haemolysis.

    Honey has always been regarded as a food which is advantageous for one's health and as a product which has healing qualities. For this reason, is necessary to protect consumers from the fraudulent mislabeling of inferior honeys. The purpose of this study was to investigate some properties of artisanal honey samples (n=45) collected from the Northwest of Portugal by using different honey analysis tests such as moisture, ash, pH, free acidity, electrical conductivity, hydroxymethylfurfural (HMF), apparent sucrose, reducing sugars and diastase activity. 77.8% of the total exceeded the quality parameters and should be labeled as "virgin" (humidity ≤18% and HMF ≤25 mg/kg). The present study found a linear correlation (y=0.551x-0.089; R=0.995) between the electrical conductivity of honeys and their ash content. All of the samples showed an Erica sp. pollen percentage ≥15%, and 42% of the total were monofloral Erica sp. In respect to coliforms and Salmonella's presence, all the honey's samples shown to be negative. The existence of sulphite-reducing Clostridia was low, and well below the established limit by MERCOSUR. Yeasts, moulds and aerobic mesophiles were detected in low amounts.

    Full Text Available The Mexican sport of charrería, or Mexican rodeo, developed in post-conquest Mexico as a way of preserving and celebrating traditional cowboy riding and livestock handling skills. Today, charrería is considered the national sport of Mexico and the charro (cowboy is also a celebrated icon of Mexicanness. Special handcrafted ropes used in charrería, known as sogas finas, or charro lariats, are made from the fibers of the Agave inaequidens. The manufacture of charro ropes is an artisinal practice that requires both cultural and botanical knowlege. In the last ten years, there has been a significant decline in the A. inaequidens population in the Cerro Viejo mountain range of the central-western Mexican state of Jalisco, putting the financial wellbeing of local lariat artisans at risk. Drawing on fieldwork and laboratory analysis conducted from 2002 through 2010, we discuss the socio-cultural significance of charro lariats, detail the harvesting of A. inaequidens in relation to lariat craftsmanship, document the physical characteristics of the A. inaequidens from this region, and describe the relationship between traditional knowledge and the local economy. The goal of this research is two-fold: 1 to stimulate feedback between producers and consumers in an attempt to leverage the existing business cluster based on traditional knowledge and 2 to initiate dialogue concerning conservation, domestication, and sustainable management of the wild A. inadequidens population.

    A total of 143 presumptive yeast isolates were obtained from the predominant microflora of 21 short-ripened starter-free raw cow's milk cheeses made in Galicia (NW Spain), and the following 68 isolates were identified by both genotyping and sequencing methods: Yarrowia lipolytica (21 isolates), Kluyveromyces lactis (18), Debaryomyces hansenii (11), Pichia guilliermondii (11), Pichia fermentans (4) and Saccharomyces cerevisiae (3). Of these, Y. lipolytica and K. lactis displayed the strongest extracellular proteolytic activity on skim milk agar, and none of the D. hansenii isolates showed any activity on this medium. Y. lipolytica also displayed the highest lipolytic activity on Tween 80 and on tributyrin. This species, which was characterized by production of butanoic acid, free fatty acid esters and sulfur compounds in pasteurized whole milk, was responsible for rancid and cheesy flavors. K. lactis mainly produced acetaldehyde, ethanol, branched chain aldehydes and alcohols, and acetic acid esters, which were responsible for alcoholic, fruity and acetic notes. The volatile profiles of D. hansenii were rather limited and characterized by high levels of methyl ketones. Most of the yeast isolates were described as tryptamine producers, although low concentrations of histamine were produced by five Y. lipolytica and two P. fermentans isolates. We conclude that selected Y. lipolytica strains could be used as adjunct cultures in the manufacture of Arzúa-Ulloa and Tetilla cheeses, and selected K. lactis strains could be used as co-starters in the manufacture of acid curd Cebreiro cheese, thus contributing to the sensory quality and typicality of the cheeses.

    Bioactive vitamin D is a steroid hormone transported in blood via the vitamin D binding protein (DBP). Our study aimed to investigate the vitamin D status in a young Lebanese population and study the association of hypovitaminosis with levels of DBP. Polymorphisms in the GC gene that encodes DBP were also screened. Blood samples were collected from 179 university students. Vitamin D status and DBP levels were assayed by enzyme-linked immunosorbent assay (ELISA). DNA was extracted from 128 participants, and genotyping of the two GC gene SNPs, rs7041, and rs4588, was carried out by restriction fragment length polymorphism. Forty-seven percent of participants had hypovitaminosis D (hypovitaminosis D observed in sunny countries.

    The Canaanites inhabited the Levant region during the Bronze Age and established a culture that became influential in the Near East and beyond. However, the Canaanites, unlike most other ancient Near Easterners of this period, left few surviving textual records and thus their origin and relationship to ancient and present-day populations remain unclear. In this study, we sequenced five whole genomes from ∼3,700-year-old individuals from the city of Sidon, a major Canaanite city-state on the Eastern Mediterranean coast. We also sequenced the genomes of 99 individuals from present-day Lebanon to catalog modern Levantine genetic diversity. We find that a Bronze Age Canaanite-related ancestry was widespread in the region, shared among urban populations inhabiting the coast (Sidon) and inland populations (Jordan) who likely lived in farming societies or were pastoral nomads. This Canaanite-related ancestry derived from mixture between local Neolithic populations and eastern migrants genetically related to Chalcolithic Iranians. We estimate, using linkage-disequilibrium decay patterns, that admixture occurred 6,600-3,550 years ago, coinciding with recorded massive population movements in Mesopotamia during the mid-Holocene. We show that present-day Lebanese derive most of their ancestry from a Canaanite-related population, which therefore implies substantial genetic continuity in the Levant since at least the Bronze Age. In addition, we find Eurasian ancestry in the Lebanese not present in Bronze Age or earlier Levantines. We estimate that this Eurasian ancestry arrived in the Levant around 3,750-2,170 years ago during a period of successive conquests by distant populations. Copyright © 2017 The Author(s).

    Full Text Available The concentrations of eight trace elements, Cadmium (Cd, lead (Pb, iron (Fe, zinc (Zn, manganese (Mn, copper (Cu, mercury (Hg and arsenic(As in sediment and water were assessed in four artisanal and small-scale mining(ASM localities in the Amansie West District (6°28′N 1°53′W of Ghana along two river courses from May 2011to July 2011. Triplicate water and sediment samples were randomly taken at five different points at each of the localities and the elements determined using Atomic Absorption Spectrophotometer (AAS . Using the Geo-accumulation Index( Igeo assessment, the sediments were found to be polluted to different degrees with Cu(Uncontaminated to moderately contaminated/Moderately contaminated, Hg (Uncontaminated to moderately contaminated/Moderately contaminated and As(Moderately contaminated/Moderately to strongly contaminated. The Enrichment Factor (EF indicated human influence - artisanal mining activities on the sediment concentration of Cd and Pb for all the localities and only some of the localities for the rest of the trace elements. The elements are major sediment pollutants ( EF > 2 in one or more of the localities. The Igeo and EF gave diverse status of the sediment qualities of the localities. Cd, Pb, Hg and As water concentrations in the four artisanal mining localities were all found to be above the WHO maximum acceptable of levels for drinking water. Inhabitants in the mining localities face the risk of getting various diseases by drinking the waters contaminated with the trace elements.

    Full Text Available In Argentina, the franciscana dolphin is one of the most vulnerable cetaceans regularly entangled in coastal artisanal fishery nets. The aim of this paper is to estimate the species' incidental mortality on the Southern coast of Buenos Aires province through interviews with the captains of artisanal fishing vessels, in the period 2006-2009. Franciscana bycatch was reported for gillnets and shrimper gear all year round but it occurred more frequently between October and February, at 5 km offshore and 10-20 m depth. The estimated mean annual incidental mortality was 107 dolphins (CI 95% = 87-129, 92 caught in gillnets (CI 95% = 73-112 and 15 in shrimpers' gear (CI 95% = 8-25 with a capture per unit effort of 0.029 dolphins per km of gillnet (CI 95% = 0.023-0.036 and 0.022 per shrimpe r's net (CI 95% = 0.012-0.035. Annual fluctuations were due to differences in the number of gillnetting fishing days. If mortality estimates for the Northern coast are also taken into account, values attain a maximum of 360-539 dolphins bycaught in the entire Buenos Aires province, representing 2.5-3.7% of the species' abundance in Argentina. This will inevitably lead to the decline of franciscana dolphin populations in the near future unless alternative fishing grounds are identified and alternative gearadopted.Na Argentina, a toninha é um dos cetáceos mais vulneráveis devido às capturas por rede de pesca artesanal.

  11. Biogenic amines in raw and processed seafood

    Directory of Open Access Journals (Sweden)

    Pierina eVisciano

    2012-06-01

    Full Text Available The presence of biogenic amines in raw and processed seafood, associated with either time/temperature conditions or food technologies is discussed in the present paper from a safety and prevention point of view. In particular, storage temperature, handling practices, presence of microbial populations with decarboxylase activity and availability of free amino acids are considered the most important factors affecting the production of biogenic amines in raw seafood. On the other hand, some food technological treatments such as salting, ripening, fermentation or marination can increase the levels of biogenic amines in processed seafood. The consumption of high amount of biogenic amines, above all histamine, can result in food borne poisoning which is a worldwide problem. The European Regulation established as maximum limits for histamine, in fishery products from fish species associated with high histidine amounts, values ranging from 100 to 200 mg/kg, while for products which have undergone enzyme maturation treatment in brine, the aforementioned limits rise to 200 and 400 mg/kg. Preventive measures and emerging methods aiming at controlling the production of biogenic amines are also reported for potential application in seafood industries.

    Soil and water samples were collected from a watershed in Burkina Faso where illegal artisanal gold extraction using cyanidation occurs. The samples were used to evaluate cyanide contamination and the presence of cyanide degrading bacteria (CDB). Free cyanide (F-CN) was detected in all samples, with concentrations varying from 0.023 to 0.9 mg kg(-1), and 0.7-23 μg L(-1) in the soil and water samples, respectively. Potential CDB also were present in the samples. To test the effective F-CN degradation capacity of the isolated CDB species, the species were cultivated in growth media containing 40, 60 or 80 mg F-CN L(-1), with or without nutrients, at pH 9.5 and at room temperature. More than 95% of F-CN was degraded within 25 h, and F-CN degradation was associated with bacterial growth and ammonium production. However, initial concentrations of F-CN higher than 100 mg L(-1) inhibited bacterial growth and cyanide degradation. Abiotic tests showed that less than 3% of F-CN was removed by volatilization. Thus, the degradation of F-CN occurred predominately by biological mechanisms, and such mechanisms are recommended for remediation of contaminated soil and water. The bacteria consortium used in the experiment described above exist in a Sahelian climate, which is characterized by a long hot and dry season. Because the bacteria are already adapted to the local climate conditions and show the potential for cyanide biodegradation, further applicability to other contaminated areas in West Africa, where illegal gold cyanidation is widespread, should be explored.

  13. Linking fishery management and conservation in a tropical estuarine lagoon: biological and physical effects of an artisanal fishing gear

    Science.gov (United States)

    Rueda, M.; Defeo, O.

    2003-04-01

    Information coming from fishery monitoring, surveys and experimental fishing with participation of fishers was employed to determine the impact of an artisanal gear, 'boliche', on the biodiversity of the Ciénaga Grande de Santa Marta (CGSM), an estuarine lagoon on the Caribbean coast of Colombia. Fishery monitoring (catch data) included landings before (1968 and 1978) and after (1994-1996) the introduction of the boliche in the CGSM (1985), whereas surveys were conducted seasonally during 1993-1994. Fishing experiments involved evaluating different mesh sizes and the short-term effect of physical disturbance by the boliche. Monitoring suggested potential trophic effects of this fishing gear: the catch of large, long-lived, carnivorous species declined after the introduction of the boliche in the CGSM, whereas catch rates of smaller, shorter-lived, and lower trophic level species increased. Surveys revealed that the boliche retained 41 species. The by-catch made up 62% of the total catch and the remaining 38% involved the three target species Eugerres plumieri, Mugil incilis and Cathorops spixii. Selectivity experiments showed that 2.5 in. stretched mesh size gill nets caught more species than the 3.0-in. mesh. The smaller mesh also increased the risk of a critical reduction in the spawning stock of target species (notably E. plumieri); a situation that could affect the fish community if mesh sizes lower than 2.5 in. were intensively used. Suspended particulate matter significantly increased after fishing activity, with higher resuspension on mud-shells and mud substrata, whereas dissolved oxygen showed no appreciable changes after fishing operations. Notwithstanding, the activity of the boliche would generate sediment resuspension between 382 and 470 t day -1, which could lead to potential cascade impacts on water quality. We propose a framework of redundancy in management measures in order to simultaneously reach management and conservation goals.

    This is the first assessment of catch rates for the legal, artisanal green turtle, Chelonia mydas, fishery in Caribbean Nicaragua. Data were collected by community members, monitoring up to 14 landing sites from 1991 to 2011. We examined take levels, and temporal and spatial variability in catch rates for the overall fishery, by region, and community using General Additive Mixed Models (GAMMs). More than 171,556 green turtles were killed during the period, with a mean estimated minimum 8,169±2,182 annually. There was a statistically significant decline in catch rates overall. Catch rates peaked in 1997 and 2002, followed by a downward trend, particularly from mid-2008 to the end of the study period. Similar downward trends were evident in both study regions. Community specific catch rate trends also indicated declines with decreases ranging from 21% to 90%. Decrease in catch rates in Nicaragua is cause for concern even though the principal source rookery at Tortuguero, Costa Rica, shows an increase in nesting activity. Explanations for the apparent discrepancy between the increasing trend at Tortuguero and decreasing catch rate trends in Nicaragua include: i) an increase in reproductive output, ii) insufficient time has passed to observe the impact of the fishery on the rookery due to a time lag, iii) changes in other segments of the population have not been detected since only nesting activity is monitored, iv) the expansive northern Nicaragua foraging ground may provide a refuge for a sufficient portion of the Tortuguero rookery, and/or v) a larger than expected contribution of non-Tortuguero rookeries occurring in Nicaragua turtle fishing areas. Our results highlight the need for close monitoring of rookeries and in-water aggregations in the Caribbean. Where consumptive use still occurs, nations sharing this resource should implement scientifically based limits on exploitation to ensure sustainability and mitigate impacts to regional population diversity.

There was a statistically significant decline in catch rates overall. Catch rates peaked in 1997 and 2002, followed by a downward trend, particularly from mid-2008 to the end of the study period. Similar downward trends were evident in both study regions. Community specific catch rate trends also indicated declines with decreases ranging from 21% to 90%. Decrease in catch rates in Nicaragua is cause for concern even though the principal source rookery at Tortuguero, Costa Rica, shows an increase in nesting activity. Explanations for the apparent discrepancy between the increasing trend at Tortuguero and decreasing catch rate trends in Nicaragua include: i an increase in reproductive output, ii insufficient time has passed to observe the impact of the fishery on the rookery due to a time lag, iii changes in other segments of the population have not been detected since only nesting activity is monitored, iv the expansive northern Nicaragua foraging ground may provide a refuge for a sufficient portion of the Tortuguero rookery, and/or v a larger than expected contribution of non-Tortuguero rookeries occurring in Nicaragua turtle fishing areas. Our results highlight the need for close monitoring of rookeries and in-water aggregations in the Caribbean.

    Full Text Available This article is one of three synthesis reports resulting from an integrated assessment (IA of artisanal and small-scale gold mining (ASGM in Ghana. Given the complexities that involve multiple drivers and diverse disciplines influencing ASGM, an IA framework was used to analyze economic, social, health, and environmental data and to co-develop evidence-based responses in collaboration with pertinent stakeholders. We look at both micro- and macro-economic processes surrounding ASGM, including causes, challenges, and consequences. At the micro-level, social and economic evidence suggests that the principal reasons whereby most people engage in ASGM involve “push” factors aimed at meeting livelihood goals. ASGM provides an important source of income for both proximate and distant communities, representing a means of survival for impoverished farmers as well as an engine for small business growth. However, miners and their families often end up in a “poverty trap” of low productivity and indebtedness, which reduce even further their economic options. At a macro level, Ghana’s ASGM activities contribute significantly to the national economy even though they are sometimes operating illegally and at a disadvantage compared to large-scale industrial mining companies. Nevertheless, complex issues of land tenure, social stability, mining regulation and taxation, and environmental degradation undermine the viability and sustainability of ASGM as a livelihood strategy. Although more research is needed to understand these complex relationships, we point to key findings and insights from social science and economics research that can guide policies and actions aimed to address the unique challenges of ASGM in Ghana and elsewhere.

    Indonesian artisanal and small-scale gold mining activities (ASGM) have been described for the islands of Borneo (Kalimantan) and Sulawesi. But the increased gold price over recent years has seen operations extend to the islands of Lombok and Sumbawa. For the current research, an environmental assessment was conducted across three new ASGM locations. Gold is recovered by miners through a two-stage process of whole-ore amalgamation and cyanidation. Waste (tailings) is discharged to land or sea with no concern for contaminants in the tailings. The gold grade of ore is up to 5000 mg kg(-1). The mean gold grade of the amalgamation tailings is 7 mg kg(-1), dropping to 1.2 mg kg(-1) for the cyanidation tailings. The mean mercury concentration of the amalgamation tailings is about 3000 mg kg(-1) and greater than 1600 mg kg(-1) for the cyanidation tailings. Samples of paddy rice grain collected adjacent to cyanidation tailings ponds showed methyl mercury concentrations greater than 100 ng g(-1). This is five times above the Chinese permissible level for total mercury in food crops. The mean total mercury concentration in hair of Lombok ASGM workers was greater than that in a non-exposed population; however there was no difference in methyl mercury concentration. This indicates the primary pathway of mercury exposure is inhalation of volatile mercury in the atmosphere. Future exposure may come from ingestion of methyl mercury contaminated rice where discharge of cyanide tailings to paddies continues. To protect the environment and to enhance the sustainability of ASGM, appropriate tailings management must be implemented. The gold grade of the tailings indicates that the residual value might be recoverable with appropriate technology. Ongoing research is investigating systems such as phytoextraction that might assist ASGM operators in Lombok and Sumbawa to improve their environmental performance.

    The objective of this study was to evaluate the bacteriological quality of raw cow's milk utilized for the production of Traditional Minas Serro cheese, a Brazilian farmstead raw milk cheese. Raw milk samples were collected from six farmstead cheese operations manufacturing raw milk cheese from cow's milk. Coliform count (CC) and Escherichia coli counts were determined using Petrifilm™ EC plates, and Staphylococcus aureus counts were determined using Petrifilm™ Staph Express count plates. The standard plate count (SPC) was determined using plate count agar. The somatic cell count (SCC) was determined with a DeLaval cell counter. The detection of Listeria monocytogenes was based in the ISO 11290-1 protocol. A total of 165 samples were analyzed, and the SPC was 1.85-7.88 log CFU/mL. Coliform were detected in 140 (84.8%) of the 165 samples, with counts of 1-6.39 log CFU/mL. E. coli was detected in 17 (10.3%) samples, with counts of 1-2.18 log CFU/mL. The SCC in raw milk was 10,000-1,390,000 cells per mL, with mean and geometric mean values of 247,000 and 162,181, respectively. The SCC did not differ significantly between the seasons (p>0.05), but differed between different farms (pcount was 1.47-5.03 log CFU/mL. The median of SPC, CC, and S. aureus counts differed significantly between seasons and between farms (pbacterial (including pathogenic) presence.

    For chemical industries, fresh water availability is a pre-requisite for sustainable operation. However, in many delta areas around the world, fresh water is scarce. Therefore, the E4 Water project (www.e4water.eu) comprises a case study at the Dow site in Terneuzen, The Netherlands, which is designed to develop commercial applications for mild desalination of brackish raw water streams from various origins to enable reuse in industry or agriculture. This study describes an effective two-stage work process, which was used to narrow down a broad spectrum of desalination technologies to a selection of the most promising techniques for a demonstration pilot at 2-4 m³/hour. Through literature study, laboratory experiments and multi-criteria analysis, nanofiltration and electrodialysis reversal were selected, both having the potential to attain the objectives of E4Water at full scale.

    Here, we review what is known about the microorganisms present in raw milk, including milk from cows, sheep, goats and humans. Milk, due to its high nutritional content, can support a rich microbiota. These microorganisms enter milk from a variety of sources and, once in milk, can play a number of roles, such as facilitating dairy fermentations (e.g. Lactococcus, Lactobacillus, Streptococcus, Propionibacterium and fungal populations), causing spoilage (e.g. Pseudomonas, Clostridium, Bacillus and other spore-forming or thermoduric microorganisms), promoting health (e.g. lactobacilli and bifidobacteria) or causing disease (e.g. Listeria, Salmonella, Escherichia coli, Campylobacter and mycotoxin-producing fungi). There is also concern that the presence of antibiotic residues in milk leads to the development of resistance, particularly among pathogenic bacteria. Here, we comprehensively review these topics, while comparing the approaches, both culture-dependent and culture-independent, which can be taken to investigate the microbial composition of milk.

    These series of lectures describes the work that lies between the raw data taken by the detector elements and the physics variables used to study particular reactions. We start by defining some simple physics variables of interest, then describe the fitting process used to extract values from the observed patterns in typical detectors. This is followed by a discussion of the various problems of pattern recognition in tracking, calorimetry and particle identification detectors. The process of calibration and alignment is surveyed, with emphasis on getting "reasonable" results in the absence of formally complete information. Finally, the role of Monte Carlo simulation in understanding the quality of the obtained information is examined. Throughout, we emphasize how the use of "composite" observables is required due to what our instrumentation and reconstruction can achieve.

    Full Text Available Purposeful use of proteins of connecting fabrics is based first of all on structural and mechanical and physical and chemical properties of collagen, his physiology to a human body. Traditional source of collagen is the split of skins of the cattle, but in view of the objective reasons (spongy encephalopathy, reduction of a livestock of cattle, there was a need for search of alternative sources. The particular interest and popularity represent collagenic proteins in biomedical technologies, when receiving surgical sutural materials, wound healing means, prolongator of medicines, artificial organs and fabrics, implatant. New data on use the collagen containing of sources are directly connected with expansion of a source of raw materials of processing industries of agrarian and industrial complex on the basis of deep processing of biological resources and their maximum involvement in the main and special production with significant growth in an exit of useful products from raw materials unit. In this regard, researches of a microstructure of skins and fractional composition of proteins of objects of research are conducted; data on the general chemical composition and the content of collagen in them are received. Experimental data showed that the most perspective source of collagen from the studied fishes of internal reservoirs is the skin of a silver carp that is caused by the high content of target substance collagen, the low content of fat. The technology of receiving collagenic substances with the high technical characteristics allowing to apply them in production of medical materials is proved and realized in vitro. The comparative analysis showed that substances from a split of skins of cattle and a silver carp have an identical set of amino acids, but are characterized by the different content of separate amino acid s.

    Full Text Available Sea turtles are reptiles that occur on the Brazilian coast, mainly on nesting and feeding grounds. The consumption of turtle meat and eggs is an ancient habit in many coastal communities around the world. The main dangers that threaten these species are the increase in fishing and the drastic changes in the environment. This study aimed to elucidate the interaction between the artisanal fishermen and the sea turtles in Cananéia, São Paulo state, Brazil. Local fishermen had developed an artisanal trap to fish, the “cerco-fixo”, and through interviews and illustrations, as well as by accompanying the fishermen’ daily activities, three main aspects were verified: (i the perception of the fishermen about the sea turtles; (ii the identification of species and morphological characteristics of these animals; and (iii a description of the incidental bycatch of sea turtles in these traps. The data indicates that this fishing trap is not harmful to the sea turtles. Location of traps can influence the capture of these animals, particularly those traps placed on rocky shores and other similiar points.

    Full Text Available This article aims to analyze the social representations of small-scale artisans working for associated Association of Artisans and food producers Homemade of Viçosa, Minas Gerais State-Brazil (Adapac. To this end we have tried to identify and analyse the trajectory of the craftsmen and the reasons for becoming involved with crafts and renditions of the craft for craftsmen linked to this Association. The methodological strategy adopted for the research consisted in case study. As an instrument of data collection, were used to survey participant and application of semi-structured interviews. The method of "content analysis" was used in the Organization and analysis of data. For discussion of the results were defined two categories: (i motivations for the craft and (ii representations of the craft. The results show that this type of work associates itself as the premier opportunity to occupation and income generation found by some members and another as vocation and manual skills. For women the social representations of craft relate the condition of personal satisfaction and possibility of reconciliation with the domestic activities, while for men representations indicate the enhancement of the economic dimension of the craft, distinguishing it from domestic activities.

    Full Text Available Mercury concentrations in the environment (river sediments and fish and in the hair of artisanal gold miners and inhabitants of the Gorontalo Utara Regency were determined in order to understand the status of contamination, sources and their impacts on human health. Mercury concentrations in the sediments along the Wubudu and Anggrek rivers are already above the tolerable level declared safe by the World Health Organization (WHO. Meanwhile, commonly consumed fish, such as snapper, have mercury levels above the threshold limit (0.5 μg/g. The mean mercury concentrations in the hair of a group of inhabitants from Anggrek and Sumalata are higher than those in hair from control group (the inhabitants of Monano, Tolinggula and Kwandang. The mean mercury concentration in the hair of female inhabitants is higher than that in the hair of male inhabitants in each group. Neurological examinations were performed on 44 participants of artisanal and small-scale gold mining (ASGM miners and inhabitants of Anggrek and Sumalata. From the 12 investigated symptoms, four common symptoms were already observed among the participants, namely, bluish gums, Babinski reflex, labial reflex and tremor.

    Considering that both Western Science and Local Knowledge Systems share a common ground—observations of the natural world—the dialogue between them should not only be possible, but fruitful. Local communities whose livelihoods depend on traditional uses of the local biodiversity not only develop knowledge about nature, making several uses of such knowledge, but, with that process, several inquiries about nature can be raised. Here we present our experience with the engagement of Western Science with golden grass artisan's knowledge about the buriti palm (M. flexuosa). We applied 25 semi-directive interviews, combined with field diary and participative observation, in two quilombola communities from Jalapão region (Central-Brazil). One of the inquiries that emerged from the artisan's perspectives was about the differences between male and female buriti palms' fiber. We then engaged both local and scientific perspectives regarding this issue using plant anatomy as a dialogue instrument. Here we describe this experience and resort to Paulo Freire's ideas on dialogue to argue that, to integrate Western Science and Local Knowledge Systems in a collaborative and contextualized perspective, the research should be faced as a mutual learning practice.

    Full Text Available Increased consumer interest in healthier food products is driven by a variety of factors including growing awareness of the link between diet and health, the desire to age ‘gracefully’ by maintaining good health, greater convenience in meeting nutritional needs and preventing chronic diseases. In raw food diet, food is consumed predominantly or exclusively as uncooked and unprocessed raw food; the main components of the diet are fruits, nuts, seeds, and sprouted grains and beans. The aim of this study was to obtain two raw-vegan bars using dry raw materials and to establish the physicochemical and sensory characteristics of the products. Raw-vegan bars were formulated using fruits and seeds (cranberries, figs, raisins, raspberries, cashew, chia seeds, etc. and binding agents (honey. Raw-vegan bars stands out among fast foods due to their balanced nutritional content and convenience.

    Full Text Available The state of Michoacán, México, has almost 50 collective trademarks registered for artisanal products, which were created by initiative of different state institutions. This article aims to understand the different influences that are mediated by law when collective forms of intellectual property are incorporated and negotiated by different institutions with different aims within the realm of the state. By looking closely at the experience in Michoacán, I argue that two economic/cultural agendas can be identified. On the one hand, there is the federal agenda that aims for a national and international projection of a Mexican product, focused on the successfully industrialized national products closely linked with México's imagery for a foreign audience. On the other hand, there are the expectations of Michoacán's local government, which are strongly related with a pluralist discourse and with the different policy approaches it inspires. Between the two, the country’s cultural agenda becomes shaped by economic concerns that are, in turn, defined by the worldviews of state institution's agents. El estado de Michoacán, México, tiene casi 50 marcas colectivas de productos artesanales, que fueron registradas por iniciativa de diferentes instituciones estatales. Este artículo busca comprender las variadas influencias que son mediadas por el derecho cuando se incorporan formas colectivas de propiedad intelectual, mediante la negociación de diferentes instituciones con diferentes objetivos dentro del ámbito estatal. A través de la experiencia de Michoacán, sostengo que se pueden identificar dos agendas económicas/culturales. Por un lado, se encuentra la agenda federal que busca una proyección nacional e internacional de un producto identificable como mexicano, enfocándose en los productos nacionales que han tenido una industrialización exitosa. Por otro lado, se encuentran las expectativas del gobierno local de Michoacán, que se

    Full Text Available Rhinobatos percellens is one of three species of Rhinobatidae found on Brazilian shores and is one of the most abundant species on the shallow continental shelf of Paraná and Santa Catarina States. Specimens caught by artisanal fishery between July/2001 and March/2003 by fishing communities located on the frontier between two southern Brazilian States (Paraná and Santa Catarina had their stomach contents analyzed. According to the Alimentary Index (IAi, Decapoda (69% and Teleostei (22% were the main items consumed. Polychaeta, a common prey consumed by several benthonic fishes, was poorly represented in the feeding of R. percellens. This fact may be related to the availability of prey in the environment, or to the size of the guitarfish analyzed (ontogeny. Seasonal variance of main preys (with higher IAi was observed: Dendrobranchiata and Pleocyemata displayed higher percentages in spring and autumn, Teleostei in the winter and Brachyura during the summer.Rhinobatos percellens é uma das três espécies de Rhinobatidae encontrada na costa brasileira e uma das espécies de elasmobrânquio mais abundante na plataforma continental dos estados do Paraná e Santa Catarina.

  18. Economic Efficiency of Artisanal Fishing Households under Oil Pollution Environment in the Niger Delta Region of Nigeria

    Directory of Open Access Journals (Sweden)

    Gbigbi, TM.

    2014-01-01

    Full Text Available Fish supplies more than 87% of the animal protein in Nigeria, and more than 90% of coastal communities depend solely on fishing and fisheries related activities for their survival. Available information however, shows that Nigeria's inland water bodies are producing less than 13% of their estimated fishery potential. And domestic demand for fish has never been met by dependence on output from available aquatic sources. Nigeria therefore imports over US$ 200 million worth of frozen fish per annum. The capacity of artisanal fisheries to play its role of bridging this food gap, providing employment and generating income, particularly for the coastal communities in Nigeria, will largely depend on the adoption of appropriate management strategies that will ensure efficiency and sustainability given their debilitating oil pollution environment. This study employed a Cobb- Douglas stochastic frontier cost function to measure the level of economic efficiency and its determinants among these households. A multi-stage random sampling technique was used to select 160 respondents from whom input-output data, prices and socioeconomic characteristics were obtained. The results of the analysis showed that individual levels of economic efficiency ranged from 0.10 - 0.96 with a mean of 0.68. While age, household size and number of fishing trips made in a week decreased, access to credit, membership of co-operative society, and oil spill increased, significantly, the respondents' level of economic inefficiency. These observations particularly suggest that the farmers were yet to harness the potentials of farm credit and membership of cooperative societies in their farm business, perhaps as a result of poverty. We recommend training workshops and seminars to remedy this. There is also the need for policies that could compel oil companies to minimize oil spill within the farmers' fishing environment. The adverse effects of oil spill on the environment and the

    Emissions of elemental mercury, Hg(0), from artisanal small-scale gold mining activities accounted for 37% of total global Hg(0) emissions in 2010. People who live near gold-mining areas may be exposed to high concentrations of Hg(0). Here, we assessed the human health risk due to Hg(0) exposure among residents of Palu city (Central Sulawesi Province, Indonesia). The area around the city has more than 60t of gold reserves, and the nearby Poboya area is the most active gold-mining site in Indonesia. Owing to its geography, the city experiences alternating land and sea breezes. Sampling was done over a period of 3 years (from 2010 Aug. to 2012 Dec.) intermittently with a passive sampler for Hg(0), a portable handheld mercury analyzer, and a mercury analyzer in four areas of the city and in the Poboya gold-processing area, as well as wind speeds and directions in one area of the city. The 24-h average concentration, wind speed, and wind direction data show that the ambient air in both the gold-processing area and the city was always covered by high concentration of mercury vapor. The Hg(0) concentration in the city was higher at night than in the daytime, owing to the effect of land breezes. These results indicate that the inhabitants of the city were always exposed to high concentrations of Hg(0). The average daytime point-sample Hg(0) concentrations in the city, as measured with a handheld mercury analyzer over 3 days in July 2011, ranged from 2096 to 3299ngm(-3). In comparison, the average daytime Hg(0) concentration in the Poboya gold-processing area was 12,782ngm(-3). All of these concentrations are substantially higher than the World Health Organization air-quality guideline for annual average Hg exposure (1000ngm(-3)). We used the point-sample concentrations to calculate hazard quotient ratios by means of a probabilistic risk assessment method. The results indicated that 93% of the sample population overall was at risk (hazard quotient ratio ≥1 and cut off at

    Raw bagasse or sugar cane cellulosic residues were modified using acylation grafting with fatty acid. The capability of the grafted bagasse to absorb oil from aqueous solution was studied and compared with the raw bagasse. It was found that the grafted material was significantly more hydrophobic than the raw bagasse. This grafted bagasse had little affinity for water and good affinity for oil. It was also found that bleaching of raw bagasse did not enhance its oil absorptivity. The grafted raw bagasse would be most suitable for applications where oil is to be removed from an aqueous environment. For oil absorbing applications in the absence of water, the raw bagasse was an excellent material.

    Full Text Available Three high belite laboratory clinkers were prepared from traditional and alternative raw materials. Reference clinker was obtained from 77% limestone, 11% sandy clays, 11% fatty clays and 1% iron scales. The fatty clays were replaced by red brick powder in the raw meal of the second clinker and were lowered to 2% with the replacement of 10% of the limestone by egg shells in the third clinker. The SEM examination revealed clear presence of crossed striae and twinning in the rounded belite grains of the reference clinker caused by the transformation of the α´-belite to the β polymorph. Striae were weaker in the second and third clinkers indicating a probable stabilization of the α ‘-belite polymorph. Compressive strength of the respective cements were attained first after 28 days and the early strength did not improve with increasing fineness. Higher compressive strength values were found for the cement prepared from second clinker.Se han preparado tres clinkeres de laboratorio con altos contenidos en belita a partir de materias primas tradicionales y alternativas. El clinker de referencia se obtuvo a partir de una mezcla de caliza, arcillas arenosas y grasas y limaduras de hierro. Las arcillas grasas fueron sustituidas por polvo de ladrillo rojo en la preparación del segundo clinker, y en el tercero el contenido de arcilla grasa fue de solo un 2% y parte de la caliza fue sustituida por cascara de huevo. El estudio realizado por SEM muestra superficies estriadas alrededor de los granos de belita que indican una transformación del polimorfo α´ a la forma β-C₂S, durante el enfriamiento. Esas estrías son menos marcadas en el segundo y tercer clinker, indicando, una estabilización del polimorfo α´-C₂S. Los valores de resistencias a compresión de los correspondientes cementos, a 28 días de curado, no se ven incrementados por la finura de dichos cementos. Las mayores resistencias se obtuvieron en el cemento preparado a partir del cl

    Recycling human metabolic and plastic wastes minimizes cost and increases efficiency by reducing the need to transport consumables and return trash, respectively, from orbit to support a space station crew. If the much larger costs of transporting consumables to the Moon and beyond are taken into account, developing waste recycling technologies becomes imperative and possibly mission enabling. Reduction of terrestrial waste streams while producing energy and/or valuable raw materials is an opportunity being realized by a new generation of visionary entrepreneurs; several relevant technologies are briefly compared, contrasted and assessed for space applications. A two-step approach to nonpetroleum raw materials utilization is presented; the first step involves production of supply or producer gas. This is akin to synthesis gas containing carbon oxides, hydrogen, and simple hydrocarbons. The second step involves production of fuel via the Sabatier process, a methanation reaction, or another gas-to-liquid technology, typically Fischer-Tropsch processing. Optimization to enhance the fraction of product stream relevant to transportation fuels via catalytic (process) development at NASA Glenn Research Center is described. Energy utilization is a concern for production of fuels whether for operation on the lunar or Martian surface, or beyond. The term green relates to not only mitigating excess carbon release but also to the efficiency of energy usage. For space, energy usage can be an essential concern. Another issue of great concern is minimizing impurities in the product stream(s), especially those that are potential health risks and/or could degrade operations through catalyst poisoning or equipment damage; technologies being developed to remove heteroatom impurities are discussed. Alternative technologies to utilize waste fluids, such as a propulsion option called the resistojet, are discussed. The resistojet is an electric propulsion technology with a powered

    Full Text Available We compared the artisanal fisheries, in terms of catch strategies, productivity, and gross per capita income, at two reservoirs: the Barra Bonita (an eutrophic reservoir with some introduced species, and the Jurumirim (an oligotrophic reservoir, with no introduced species. Published data and structured interviews with fishers were used to evaluate fishing activity, fish biomass, and the financial performance of the fisheries. In the Barra Bonita Reservoir we analysed data from 745 fishing trips, from which 86,691.9 kg of fish were landed, with a mean CPUE of 62.4 kg/fisher-1 day-1. The main type of fish caught was tilapia (71,513.5 kg; CPUE of 51.5 kg/fisher-1 day-1, which constituted 82.5% of the biomass caught. In the Jurumirim Reservoir, we analysed data from 2,401 fishing trips, from which 25,093.6 kg of fish were landed, with a mean CPUE of 10.4 kg/fisher-1 day-1. The main type of fish caught was "traíra" (6,158.6 kg; CPUE of 2.6 kg/fisher-1 day-1, which constituted 24.5% of the biomass caught. Ordination analysis (PCA indicated that there was a difference in composition between the fishing reservoirs and ANCOVA showed that there was a significant difference in fish production between the reservoirs. A Student's t-test showed that fishers in the Barra Bonita Reservoir had a significantly higher gross per capita income than those from the Jurumirim Reservoir. Although the Barra Bonita Reservoir has a higher fish production and the fishers earn a higher gross per capita income, we recommend the Jurumirim Reservoir as a model for artisanal fishery management because fishing activity in this reservoir is viable in the long term and such a model would promote conservation and sustainability. This contrasts with the Barra Bonita Reservoir, in which the fishery is not viable in the long term, due to environmental problems caused by artificial eutrophication and the introduction of alien species. It is also noted that in many countries, management

    The International Raw Materials Observatory (INTRAW) project is working towards a sustainable future for the European Union in access to raw materials, from an availability, economical, and environmental framework. One of the major exercises for the INTRAW project is the evaluation of potential future scenarios for 2050 to frame economic, research, and environmental policy towards a sustainable raw materials supply. The INTRAW consortium developed three possible future scenarios that encompass defined regimes of political, economic, and technological norms. The first scenario, "Unlimited Trade," reflects a world in which free trade continues to dominate the global political and economic environment, with expectations of a growing demand for raw materials from widely distributed global growth. The "National Walls" scenario reflects a world where nationalism and economic protectionism begins to dominate, leading to stagnating economic growth and uneven dynamics in raw materials supply and demand. The final scenario, "Sustainability Alliance," examines the dynamics of a global political and economic climate that is focused on environmental and economic sustainability, leading towards increasingly towards a circular raw materials economy. These scenarios were reviewed, tested, and provided simulations of impacts with members of the Consortium and a panel of global experts on international raw materials issues which led to expected end conditions for 2050. Given the current uncertainty in global politics, these scenarios are informative to identifying likely opportunities and crises. The details of these simulations and expected responses to the research demand, technology investments, and economic components of raw materials system will be discussed.

    This article assesses the association of women's HIV/AIDS knowledge of transmission and prevention with socioeconomic status (SES). Data from the 2004 Lebanese PAPFAM (Pan-Arab Project for Family Health) survey were used. The survey was based on a representative household sample (n = 5532 households; n = 3315 women) of ever-married women aged 15 to 55 years. Adjusted analysis revolved around multivariate logistic regression models. 18% of women were knowledgeable of HIV/AIDS transmission methods and 21% of prevention methods. Income and education were significantly related to women's transmission and prevention knowledge. Significant differences were also found by region and media exposure. Women in the richest income quintile were 4 times (95% confidence interval [CI] = 2.43-6.42) more likely to be knowledgeable than those in the poorest. Women with the highest education were 2.57 times more likely (95% CI = 1.98-3.34) to be knowledgeable than those with elementary education or less. These results suggest the need for incorporating contextual regional and population differences for more effective HIV/AIDS awareness campaigns in Lebanon. © 2011 APJPH.

    Biomedical science in the 21(st) century is embedded in, and draws from, a digital commons and "Big Data" created by high-throughput Omics technologies such as genomics. Classic Edisonian metaphors of science and scientists (i.e., "the lone genius" or other narrow definitions of expertise) are ill equipped to harness the vast promises of the 21(st) century digital commons. Moreover, in medicine and life sciences, experts often under-appreciate the important contributions made by citizen scholars and lead users of innovations to design innovative products and co-create new knowledge. We believe there are a large number of users waiting to be mobilized so as to engage with Big Data as citizen scientists-only if some funding were available. Yet many of these scholars may not meet the meta-criteria used to judge expertise, such as a track record in obtaining large research grants or a traditional academic curriculum vitae. This innovation research article describes a novel idea and action framework: micro-grants, each worth $1000, for genomics and Big Data. Though a relatively small amount at first glance, this far exceeds the annual income of the "bottom one billion"-the 1.4 billion people living below the extreme poverty level defined by the World Bank ($1.25/day). We describe two types of micro-grants. Type 1 micro-grants can be awarded through established funding agencies and philanthropies that create micro-granting programs to fund a broad and highly diverse array of small artisan labs and citizen scholars to connect genomics and Big Data with new models of discovery such as open user innovation. Type 2 micro-grants can be funded by existing or new science observatories and citizen think tanks through crowd-funding mechanisms described herein. Type 2 micro-grants would also facilitate global health diplomacy by co-creating crowd-funded micro-granting programs across nation-states in regions facing political and financial instability, while sharing similar disease

    2010-01-01

    In order to precisely measure the diameters for obtaining the fineness of rolling raw silk, the physical features of raw silk are analyzed. By means of Fresnel principle, diffractions caused by different transparent raw silk filaments are analyzed and simulated. Image data of raw silk filament measured by digital CMOS camera are analyzed and processed for obtaining the precise diameters of the filament with the relative error of less than 1%. On the assumption of appropriate elliptic cross-section of the filament, the cross-section area is calculated as the fineness of the filament. Measurement experiments are carried out. Finally, some suggestions are proposed for photoelectric measuring the fineness of raw silk.

    2007-01-01

    The aim of this work was to evaluate the use of mineral coal fly ash as a raw material in the production of ceramic tiles. The samples of fly ash came from Capivari de Baixo, a city situated in the Brazilian Federal State of Santa Catarina. The fly ash and the raw materials were characterized regarding their physical chemical properties, and, based on these results; batches containing fly ash and typical raw materials for ceramic tiles were prepared. The fly ash content in the batches varied between 20 and 80 wt%. Specimens were molded using a uniaxial hydraulic press and were fired. All batches containing ash up to 60 wt% present adequate properties to be classified as several kinds of products in the ISO 13006 standard () regarding its different absorption groups (pressed). The results obtained indicate that fly ash, when mixed with traditional raw materials, has the necessary requirements to be used as a raw material for production of ceramic tiles.

    The availability and application of culture-independent tools that enable a detailed investigation of the microbiota and microbial biodiversity of food systems has had a major impact on food microbiology. This review focuses on the application of DNA-based technologies, such as denaturing gradient gel electrophoresis (DGGE), temporal temperature gradient gel electrophoresis (TTGE), single stranded conformation polymorphisms (SSCP), the polymerase chain reaction (PCR) and others, to investigate the diversity, dynamics and identity of microbes in dairy products from raw milk. Here, we will highlight the benefits associated with culture-independent methods which include enhanced sensitivity, rapidity and the detection of microorganisms not previously associated with such products.

    Full Text Available Bycatch assessments in trawl fisheries have been mainly referred to an annual scale, ignoring possible seasonal variations. In the Gulf of Salamanca, an artisanal shrimp trawl fleet operates recently and this study evaluates its bycatch for first time, considering the climatic and oceanographic seasonality that dominates the region (runoff and upwelling. 90 hauls in the calm or rainy season (November 2010 and 86 in the windy season (April 2011 were sampled on board of fishing boats. The bycatch to shrimp ratio was 2,69 (2,37 -3,21, 95 % CI and 6,37 (5,10 – 8,24, 95 % CI for the calm season and windy season respectively. We recorded a total of 101 taxa, with a large number of juveniles. The community structure of bycatch differed between seasons (ANOSIM, pStellifer spp., Symphurus caribbeanus y Callinectes sapidus, whereas, in addition, the calm season was characterized by Cathorops mapale, Anchovia clupeoides, Trichiurus lepturus, and the windy season by Larimus breviceps, Cnidaria (jellyfish, Cetengraulis edentulus (Simper. The results showed a seasonal change in the bycatch, raising the need to implement monitoring programs and management measures that address that temporal variability.

    Mercury (Hg) contamination is an issue of concern in the Amazon region due to potential health effects associated with Hg exposure in artisanal gold mining areas. The study presents a human health risk assessment associated with Hg vapor inhalation and MeHg-contaminated fish ingestion, as well as Hg determination in urine, blood, and hair, of human populations (about 325 miners and 321 non-miners) from two gold mining areas in the Brazilian Amazon (São Chico and Creporizinho, Pará State). In São Chico and Creporizinho, 73 fish specimens of 13 freshwater species, and 161 specimens of 11 species, were collected for total Hg determination, respectively. The hazard quotient (HQ) is a risk indicator which defines the ratio of the exposure level and the toxicological reference dose and was applied to determine the threat of MeHg exposure. The mean Hg concentrations in fish from São Chico and Creporizinho were 0.83 ± 0.43 and 0.36 ± 0.33 μg/g, respectively. More than 60 and 22 % of fish collected in São Chico and Creporizinho, respectively, were above the Hg limit (0.5 μg/g) recommended by WHO for human consumption. For all sampling sites, HQ resulted from 1.5 to 28.5, except for the reference area. In Creporizinho, the values of HQ are close to 2 for most sites, whereas in São Chico, there is a hot spot of MeHg contamination in fish (A2-São Chico Reservoir) with the highest risk level (HQ = 28) associated with its human consumption. Mean Hg concentrations in urine, blood, and hair samples indicated that the miners group (in São Chico: urine = 17.37 μg/L; blood = 27.74 μg/L; hair = 4.50 μg/g and in Creporizinho: urine = 13.75 μg/L; blood = 25.23 μg/L; hair: 4.58 μg/g) was more exposed to mercury compared to non-miners (in São Chico: urine = 5.73 μg/L; blood = 16.50 μg/L; hair = 3.16 μg/g and in Creporizinho: urine = 3.91 μg/L; blood = 21.04 μg/L, hair = 1.88 μg/g).

    This study aimed to select autochthonous lactic acid bacteria (LAB) with probiotic and functional properties from goat dairies and test their addition to artisanal cheese for the inhibition of Salmonella typhi. In vitro tests, including survival in the gastrointestinal tract (GIT), auto- and co-aggregation, the hemolytic test, DNase activity, antimicrobial susceptibility, antibacterial activity, tolerance to NaCl and exopolysaccharide (EPS), gas and diacetyl production were conducted for sixty isolates. Based on these tests, four LAB isolates (UNIVASF CAP 16, 45, 84 and 279) were selected and identified. Additional tests, such as production of lactic and citric acids by UNIVASF CAP isolates were performed in addition to assays of bile salt hydrolase (BSH), β-galactosidase and decarboxylase activity. The four selected LAB produced high lactic acid (>17 g/L) and low citric acid (0.2 g/L) concentrations. All selected strains showed BSH and β-galactosidase activity and none showed decarboxylase activity. Three goat cheeses (1, 2 and control) were produced and evaluated for the inhibitory action of selected LAB against Salmonella typhi. The cheese inoculated with LAB (cheese 2) decreased 0.38 log10 CFU/g of S. Typhy population while in the cheese without LAB inoculation (cheese 1) the pathogen population increased by 0.29 log units. Further, the pH value increased linearly over time, by 0.004 units per day in cheese 1. In the cheese 2, the pH value decreased linearly over time, by 0.066 units per day. The cocktail containing selected Lactobacillus strains with potential probiotic and technological properties showed antibacterial activity against S. typhi in vitro and in artisanal goat cheese. Thus, goat milk is important source of potential probiotic LAB which may be used to inhibit the growth of Salmonella population in cheese goat, contributing to safety and functional value of the product.

    Artisanal diving fisheries are a source of income, employment and food security of coastal areas in many countries. Understanding the dynamics of these fisheries, including the spatial and temporal dynamics of fishing effort, gears and species can help to address the challenges involved in fisheries management. We aimed to analyze the differences in fishing strategies undertaken by fishers that use two different diving methods (hookah and free diving), the conditions and their potential impacts on catches when adjustments to those strategies are applied over time. For this, detailed information of fishing operations from artisanal boats in the North Pacific coast of Costa Rica was analyzed in two fishing seasons (2007-2008 and 2011-2012). Data were collected by onboard observers (fishing site, fishing time, species composition, depth and visibility). Additionally, interviews with divers were applied to obtain information of price per species, species volume and fishing operations. From the total number of trips during both seasons, hookah diving was represented by a sample size of 69.3%, while free diving, with a sample of 41.9%. More than 15 species were identified in each fishing season. Nevertheless, three categories had substantial contributions in both seasons with differences in the proportions for each case: green lobster (Panulirus gracilis), octopus (Octopus sp.) and parrotfish (Scarus perrico and S. ghobban). It is worth noting that an important proportion of catch was retained by fishers for personal consumption purposes, including species of high commercial value. Additional night diving activity, increased the number of dives from one season to another. Besides, cooperation processes in free diving fishing operations, and changes in fishing effort between seasons, defined important changes in fishing strategies. Potential causes of changes in fishing strategies and the implications for management to ensure the sustainability of these fisheries in the

    Full Text Available Nile tilapia (Oreochromis niloticus, which is exotic to South America, is the most common species caught in artisanal fisheries at the Barra Bonita Reservoir, Southeastern Brazil. This species is of great socioeconomic importance for the region and keeps active a population of about 500 fishers. In the present study we assess reproduction, food dynamics and level of exploitation of O. niloticus, caught by artisanal fisheries in the Barra Bonita Reservoir. Specimens were collected monthly, from July 2004-June 2005, and a total of 1 715 specimens were analyzed. Each specimen was examined to obtain biological and biometric data: standard length (cm, total weight (g, reproductive data (sex and stage of maturation, and stomach contents (empty, partly full, and full. We also estimated the sex ratio (by macroscopic observation of gonads, reproductive period (by ovarian development and seasonal average of gonadosomatic index in females, and feeding habits (by stomach contents. The possible relationship between abiotic factors and the reproductive period was statistically verified using Spearman’s Rank Correlation. The FiSAT (ELEFAN I package was used to assess growth parameters, mortality rates and to infer exploitation rate from standard length frequencies.

    Full Text Available We have been working on pyrolysis of some organic raw materials including different rank coals, oil shale, wood waste, animal bone, cedar shell, polypropylene waste, milk casein and characterization of obtained hard residue, tar and pyrolytic water and gas after pyrolysis. The technical characteristics of these organic raw materials have been determined and the thermal stability characteristics such as thermal stability indices (T5% and T25% determined by using thermogravimetric analysis. The pyrolysis experiments were performed at different heating temperatures and the yields of hard residue, tar, pyrolysis water and gaseous products were determined and discussed. The main technical characteristics of hard residue of organic raw materials after pyrolysis have been determined and the adsorption ability of pyrolysis hard residue and its activated carbon of organic raw materials also determined. The pyrolysis tars of organic raw materials were distilled in air condition and determined the yields of obtained light, middle and heavy fractions and bitumen like residue with different boiling temperature. This is the first time to investigate the curing ability of pyrolysis tars of organic raw materials for epoxy resin and the results of these experiments showed that only tar of milk casein has the highest (95.0%, tar of animal bone has certain (18.70% and tars of all other organic raw materials have no curing ability for epoxy resin.

    Full Text Available Tests of the strain sweep, frequency sweep and stress relaxation for raw natural rubber coagulated by microorganisms (NR-m and raw natural rubber coagulated by acid (NR-a were carried out with the use of a rubber process analyzer (RPA. The results showed that the storage torque, complex viscosity of NR-m were higher than those of NR-a while the loss factor was lower. The effect of temperature on viscosity of raw NR was studied following the Arrhenious-Frenkel-Eyring model. The viscous flow behavior of NR-m was poorer than those of NR-a. Furthermore, stress relaxation measurements of raw NR showed a longer period of relaxation for NR-m.

  14. Hepatitis B virus DNA splicing in Lebanese blood donors and genotype A to E strains: implications for hepatitis B virus DNA quantification and infectivity.

    Science.gov (United States)

    2012-10-01

    Hepatitis B virus (HBV) is one of the major viruses transmissible by blood that causes chronic infection in immunocompromised individuals. The study of 61 HBV carrier blood donors from Lebanon revealed multiple patterns of spliced HBV DNA. HBV DNA splicing was examined and quantified in samples of five genotypes and in seroconversion panels. The Lebanese sample median viral load was 1.5 ×10(2) IU/ml. All strains were genotype D, serotype ayw; 35 clustered as subgenotype D1 and 7 clustered as subgenotype D2. Three splice variants (SP1, SP1A, and Pol/S) were observed in 12 high-viral-load samples. Twenty samples of each genotype, A to E, were tested for the presence of HBV spliced DNA and SP1-specific splice variant. An unspliced HBV genome was dominant, but 100% of strains with a viral load of ≥10(5) copies/ml contained various proportions of spliced DNA. SP1 was detected in 56/100 (56%) samples in levels that correlated with the overall viral load. HBV DNA quantification with S (unspliced) and X (total DNA) regions provided different levels of viral load, with the difference corresponding to spliced DNA. During the highly infectious window period, the SP1 variant became detectable shortly after the hepatitis B surface antigen (HBsAg), suggesting a correlation between the initiation of splicing and the production of detectable levels of HBsAg. The quantification of HBV DNA with primers located outside and inside the spliced region might provide different estimations of viral load and differentiate between infectious and defective viral genomes. The role of splicing neoproteins in HBV replication and interaction with the host remains to be determined.

    2010-05-01

    The control of the raw materials used to manufacture vaccines is mandatory; therefore, a very clear process must be in place to guarantee that raw materials are traced. Those who make products or supplies used in vaccine manufacture (suppliers of culture media, diagnostic tests, etc.) must apply quality systems proving that they adhere to certain standards. ISO certification, Good Manufacturing Practices for production sites and the registration of culture media with a 'Certificate of Suitability' from the European Directorate for the Quality of Medicines and Healthcare are reliable quality systems pertaining to vaccine production. Suppliers must assure that each lot of raw materials used in a product that will be used in vaccine manufacture adheres to the level of safety and traceability required. Incoming materials must be controlled in a single 'Enterprise Resource Planning' system which is used to document important information, such as the assignment of lot number, expiration date, etc. Ingredients for culture media in particular must conform to certain specifications. The specifications that need to be checked vary according to the ingredient, based on the level of risk. The way a raw material is produced is also important, and any aspect relative to cross-contamination, such as the sanitary measures used in producing and storing the raw material must be checked as well. In addition, suppliers can reduce the risk of viral contamination of raw materials by avoiding purchases in countries where a relevant outbreak is currently declared. 2010 The International Association for Biologicals.

    2011-01-01

    Full Text Available Abstract Sliding spotlight mode is a novel synthetic aperture radar (SAR imaging scheme with an achieved azimuth resolution better than stripmap mode and ground coverage larger than spotlight configuration. However, its raw signal simulation of extended scenes may not be efficiently implemented in the two-dimensional (2D Fourier transformed domain. This article presents a novel sliding spotlight raw signal simulation approach from the wide-beam SAR imaging modes. This approach can generate sliding spotlight raw signal not only from raw data evaluated by the simulators, but also from real data in the stripmap/spotlight mode. In order to obtain the desired raw data from conventional stripmap/spotlight mode, the azimuth time-varying filtering, which is implemented by de-rotation and low-pass filtering, is adopted. As raw signal of extended scenes in the stripmap/spotlight mode can efficiently be evaluated in the 2D Fourier domain, the proposed approach provides an efficient sliding spotlight SAR simulator of extended scenes. Simulation results validate this efficient simulator.

  2. Polymers Based on Renewable Raw Materials – Part I

    Directory of Open Access Journals (Sweden)

    2013-09-01

    Full Text Available This paper gives an overview of the production and application of polymer materials based on renewable raw materials – biopolymers. It is pointed out that, investment of resources in the study of renewable raw materials in the last twenty years has led to the improvement of old and development of completely new chemical and biochemical processes for using biomass for the production of low molecular weight chemical substances, and especially for the production of biopolymers, which are biodegradable and compostable, and biopolymers which are nonbiodegradable. In the same period, producers of polymers based on fossil raw materials have also developed biopolymers that are biodegradable and some of them compostable and, most important, compatible with biopolymers based on renewable raw materials. The facts considering the state of biopolymers based on renewable raw materials on the market, and prediction of production increase over the next five years are also stated. Additionally, the main renewable raw materials and the biopolymers made from them that are already present in the world market are briefly listed. A short review of biopolymers based on cellulose from wood and annual plants is also given.

    The Patient Health Questionnaire - 9 (PHQ-9) and Generalized Anxiety Disorder - 7 (GAD-7) are short screening measures used in medical and community settings to assess depression and anxiety severity. The aim of this study is to translate the screening tools into Arabic and evaluate their psychometric properties in an Arabic-speaking Lebanese psychiatric outpatient sample. The patients completed the questionnaires, among others, prior to being evaluated by a clinical psychiatrist or psychologist. The scales' internal consistency and factor structure were measured and convergent and discriminant validity were established by comparing the scores with clinical diagnoses and the Psychiatric Diagnostic Screening Questionnaire - MDD subset (PDSQ - MDD). Results showed that the PHQ-9 and GAD-7 are reliable screening tools for depression and anxiety and their factor structures replicated those reported in the literature. Sensitivity and specificity analyses showed that the PHQ-9 is sensitive but not specific at capturing depressive symptoms when compared to clinician diagnoses whereas the GAD-7 was neither sensitive nor specific at capturing anxiety symptoms. The implications of these findings are discussed in reference to the scales themselves and the cultural specificity of the Lebanese population.

  6. Raw material ‘criticality’—sense or nonsense?

    Science.gov (United States)

    Frenzel, M.; Kullik, J.; Reuter, M. A.; Gutzmer, J.

    2017-03-01

    The past decade has seen a resurgence of interest in the supply security of mineral raw materials. A key to the current debate is the concept of ‘criticality’. The present article reviews the criticality concept, as well as the methodologies used in its assessment, including a critical evaluation of their validity in view of classical risk theory. Furthermore, it discusses a number of risks present in global raw materials markets that are not captured by most criticality assessments. Proposed measures for the alleviation of these risks are also presented. We find that current assessments of raw material criticality are fundamentally flawed in several ways. This is mostly due to a lack of adherence to risk theory, and highly limits their applicability. Many of the raw materials generally identified as critical are probably not critical. Still, the flaws of current assessments do not mean that the general issue of supply security can simply be ignored. Rather, it implies that new assessments are required. While the basic theoretical framework for such assessments is outlined in this review, detailed method development will require a major collaborative effort between different disciplines along the raw materials value chain. In the opinion of the authors, the greatest longer-term challenge in the raw materials sector is to stop, or counteract the effects of, the escalation of unit energy costs of production. This issue is particularly pressing due to its close link with the renewable energy transition, requiring more metal and mineral raw materials per unit energy produced. The solution to this problem will require coordinated policy action, as well as the collaboration of scientists from many different fields—with physics, as well as the materials and earth sciences in the lead.

    2013-01-01

    Abstract Biomedical science in the 21st century is embedded in, and draws from, a digital commons and “Big Data” created by high-throughput Omics technologies such as genomics. Classic Edisonian metaphors of science and scientists (i.e., “the lone genius” or other narrow definitions of expertise) are ill equipped to harness the vast promises of the 21st century digital commons. Moreover, in medicine and life sciences, experts often under-appreciate the important contributions made by citizen scholars and lead users of innovations to design innovative products and co-create new knowledge. We believe there are a large number of users waiting to be mobilized so as to engage with Big Data as citizen scientists—only if some funding were available. Yet many of these scholars may not meet the meta-criteria used to judge expertise, such as a track record in obtaining large research grants or a traditional academic curriculum vitae. This innovation research article describes a novel idea and action framework: micro-grants, each worth $1000, for genomics and Big Data. Though a relatively small amount at first glance, this far exceeds the annual income of the “bottom one billion”—the 1.4 billion people living below the extreme poverty level defined by the World Bank ($1.25/day). We describe two types of micro-grants. Type 1 micro-grants can be awarded through established funding agencies and philanthropies that create micro-granting programs to fund a broad and highly diverse array of small artisan labs and citizen scholars to connect genomics and Big Data with new models of discovery such as open user innovation. Type 2 micro-grants can be funded by existing or new science observatories and citizen think tanks through crowd-funding mechanisms described herein. Type 2 micro-grants would also facilitate global health diplomacy by co-creating crowd-funded micro-granting programs across nation-states in regions facing political and financial instability, while

    The purpose of this study was to evaluate adherence and identify predictors of adherence to a raw vegan diet (i.e., uncooked plant foods) following a stay at a raw vegan institute. In this cohort study of guests at a raw vegan institute, subjects completed written questionnaires upon arrival and 12 weeks later. Of 107 eligible guests, 84 participated. Mean age was 54 years, 23 were male, and 73 white. Fifty-one completed the 12-week follow-up. Eight (16%) reported their diet to be 80% raw vegan at baseline and 14 (28%) at follow-up. Based on a raw vegan dietary adherence score (range 0-42) created for this study, mean adherence (SD) increased from 15.1 (5.4) to 17.0 (5.8) over 12 weeks (p=0.03). Baseline predictors of adherence included: education (beta=0.95), severity of disease (beta=0.98), and self-efficacy to adhere (beta=0.72). Future interventions that evaluate this diet should address self-efficacy, an important, potentially remediable predictor of adherence.

    Raw milk consumption in Italy has increased over the last few years and although raw milk is characterised by cold chain, short shelf-life and the duty of boiling before domestic consumption, it is still considered a hazard. From 2010 to 2013 a monitoring survey of raw milk sold through vending machines was carried out to investigate the occurrence of several foodborne pathogens stipulated in the national legal requirements, i.e. Listeria monocytogenes, Campylobacter spp., Salmonella spp., Escherichia coli O:157 and coagulase-positive Staphylococci. A total of 127 raw milk samples were collected from 19 dairy herds in Tuscany Region, Italy. In addition, the milk samples were tested for the presence and count of Yersinia genus. Results shown that only one sample was positive for non verocytotoxin-producing E. coli O:157, whereas a total of 38 samples (29.9%) were postive for Yersinia genus; of the total 39 isolated bacteria, 23.6% were Y. enterocolitica, 2.4% Y. kristenseni and 4.7% Y. frederiksenii. None isolate was enteropathogenic; serotypes O:5 and O:8 were found in 16.6 and 13.3% of the isolates respectively, whereas none of the serotypes tested was detected in 70% of the isolates. The most probable number method revealed a count value between 0.03 and 24 MPN/mL. Based on these data a general assurance on health safety of raw milk produced and sold in Tuscany could be assessed.

    Full Text Available A short review of biopolymers based on starch (starch derivatives, thermoplastic starch, lignin and hemicelluloses, chitin (chitosan and products obtained by degradation of starch and other polysaccharides and sugars (poly(lactic acid, poly(hydroxyalkanoates, as well as some of their basic properties and application area, are given in this part. The problem of environmental and economic feasibility of biopolymers based on renewable raw materials and their competitiveness with polymers based on fossil raw materials is discussed. Also pointed out are the problems that appear due to the increasing use of agricultural land for the production of raw materials for the chemical industry and energy, instead for the production of food for humans and animals. The optimistic assessments of experts considering the development perspectives of biopolymers based on renewable raw materials in the next ten years have also been pointed out.At the end of the paper, the success of a team of researchers gathered around the experts from the company Bayer is indicated. They were the first in the world to develop a catalyst by which they managed to effectively activate CO - and incorporate it into polyols, used for the synthesis of polyurethanes in semi-industrial scale. By applying this process, for the first time a pollutant will be used as a basic raw material for the synthesis of organic compounds, which will have significant consequences on the development of the chemical industry, and therefore the production of polymers.

    A human health risk assessment of artisanal miners exposed to toxic metals in water bodies and sediments in the PresteaHuni Valley District of Ghana was carried out in this study, in line with US EPA risk assessment guidelines. A total of 70 water and 30 sediment samples were collected from surface water bodies in areas impacted by the operations of artisanal small-scale gold mines in the study area and analyzed for physico-chemical parameters such as pH, TDS, conductivity, turbidity as well as metals and metalloids such as As, Cd, Hg and Pb at CSIR-Water Research Institute using standard methods for the examination of wastewater as outlined by American Water Works Association (AWWA). The mean concentrations of As, Cd, Hg and Pb in water samples ranged from 15 μg/L to 325 μg/L (As), 0.17 μg/L to 340 μg/L (Cd), 0.17 μg/L to 122 μg/L (Pb) and 132 μg/L to 866 μg/L (Hg), respectively. These measured concentrations of arsenic (As), mercury (Hg), cadmium (Cd) and lead (Pb) were used as input parameters to calculate the cancer and non-cancer health risks from exposure to these metals in surface water bodies and sediments based on an occupational exposure scenario using central tendency exposure (CTE) and reasonable maximum exposure (RME) parameters. The results of the non-cancer human health risk assessment for small-scale miners working around river Anikoko expressed in terms of hazard quotients based on CTE parameters are as follows: 0.04 (Cd), 1.45 (Pb), 4.60 (Hg) and 1.98 (As); while cancer health risk faced by ASGM miners in Dumase exposed to As in River Mansi via oral ingestion of water is 3.1 × 10(-3). The hazard quotient results obtained from this study in most cases were above the HQ guidance value of 1.0, furthermore the cancer health risk results were found to be higher than the USEPA guidance value of 1 × 10(-4) to 1 × 10(-6). These findings call for case-control epidemiological studies to establish the relationship between exposure to the

    The evolution of physicochemical parameters, and the most important microbial groups, were determined for the following three batches of 'Cameros' goat's milk cheese during ripening: Batch R elaborated with raw milk, Batch RS elaborated with raw milk and with the addition of a starter culture, and Batch PS elaborated with pasteurized milk and with the addition of the same culture. No differences in total solids (TS) or in the content of NaCl, fat and total nitrogen (expressed as percentages of TS) were found during the ripening. The pH, fat acidity and non-protein nitrogen (NPN, expressed as a percentage of TN) showed significant differences between the batches. The inoculated batches showed the fastest drop in pH at the beginning of the ripening period, but the cheeses of Batch R showed a higher degree of lipolysis and proteolysis. The addition of a starter influenced the microbiological quality of the cheeses. Differences in the counts of Enterobacteriaceae and faecal coliforms were found between Batches R and RS after 15 days. Staphylococcus aureus increased in number during the early period of ripening and attained a population above 6 log cfu g-1 in Batch R in the period from 5 to 10 days. However, enterotoxins were not detected in this Batch. Batch R showed lower values of lactic acid bacteria at the beginning of the ripening period, but no significant differences were found between batches in the period from 5 to 15 days of ripening. At the beginning of the ripening, Lactococcus was the main lactic acid bacteria, with L. lactis lactis being predominant. After 15 days, the lactic acid bacteria counts decreased in the three batches, especially in the cheeses of Batch PS (only 2.2 log cfu g-1 was found at 60 days), as lactococci (the only lactic acid bacteria present in Batch PS) are incapable of growing under the conditions found in cheeses at the end of their ripening period. At this time, Lactobacillus was the predominant genus in Batches R and RS, with L

    Full Text Available Textile industry processes need high amounts of water for wet treatment of textiles. Therefore, high amounts of wastewater also appear containing different inorganic and organic substances depending on the used materials and processes. Raw wool is contaminated with wool wax, suint, skin flakes, dirt, sand, vegetable matter, urine and various microorganisms. The methods for raw wool scouring and cleaning today often in use are: scouring in the suint, scouring with soaps or tenside in alkaline, extraction by organic solvents and freezing. The different methods for wastewater purification after scouring in use are: settling/floculation, biological treatment, adsorptionand catalytic oxidation. In this work, wastewater treatments after improved raw wool scouring with enzymes and EDTA have been investigated. Isothermal adsorption on zeolite A, active carbon and a natural and H+ type of bentonite for removal of the obtained wastewater impurities was used. The results were determined by means of different physical-chemical test methods.

    Notwithstanding several policy initiatives in many countries over a number of years, there remains a general sense that too much municipal solid waste is generated and that too much of the waste that is generated is landfilled. There is an emerging consensus that a sustainable approach to waste management requires further development of secondary raw material markets. The purpose of this paper is to propose a theoretical economic model that focuses upon this stage of a sustainable waste management program and explores policy options that could motivate efficiency in secondary raw material markets. In particular, we show how firm profit and social welfare optimizing objectives can be reconciled in a two-product market of waste management processes: landfilling and material reclamation. Our results provide theoretical support for building out recent Circular Economy initiatives as well as for the relatively recent emergence of landfill mining as a means for procuring secondary raw materials.

    The ethanol industry of today utilizes raw materials rich in saccharides, such as sugar cane or sugar beets, and raw materials rich in starch, such as corn and wheat. The concern about supply of liquid transportation fuels, which has brought the crude oil price above 100 /barrel during 2006, together with the concern about global warming, have turned the interest towards large-scale ethanol production from lignocellulosic materials, such as agriculture and forestry residues. Baker's yeast Saccharomyces cerevisiae is the preferred fermenting microorganism for ethanol production because of its superior and well-documented industrial performance. Extensive work has been made to genetically improve S. cerevisiae to enable fermentation of lignocellulosic raw materials. Ethanolic fermentation processes are conducted in batch, fed-batch, or continuous mode, with or without cell recycling, the relative merit of which will be discussed.

    The Radar Wind Sensor (RAWS) was proposed as a complement to laser wind sensors, allowing coverage in cloudy regions excluded from laser coverage. Previous University of Kansas studies showed the feasibility of the wind measurement at various levels in the atmosphere and indicated that RAWS can also measure rain rates and ocean-surface winds. Here we discuss measurement of the wind vector in terms of the scan patterns for a conically scanned antenna. By using many measurements from cells about 66 km square and 132 km square, a least-squares algorithm gives results that are reasonable for insertion into global atmospheric models. For RAWS to be used successfully as a complement to a laser wind sensor, the design of the two sensors should be integrated and radial velocity measurements in a given atmospheric cell should be combined to get the most accurate results.
