    Full Text Available Muscoloskeletal disorders are the first cause of disability and the second cause of permanent disablement in Italy. Osteoarthritis is the most frequent rheumatic disease and affects about 4 million Italians. In spite of that, data concerning social costs are lacking. On account of this lack we measured sanitary costs of 314 patients suffering from osteoarthritis. A retrospective, prevalence- based multicentric study was performed using a bottom-up approach. The study period was 12 months and referred to 1999. Eight percent of patients didn’t take any drug for the treatment of osteoarthritis; NSAIDs were prescribed to 86.9% of patients, analgesics to 29.9%, chondroprotective drugs to 7.6%, and gastroprotective drugs to 36.9%. Total sanitary costs came to 455 € / patient / year: 122 € were spent on diagnostics, 293 € on therapy and 40 € on management of drug-related gastropathy. Since the costs of anti-inflammatory drugs came to 30 € we calculated iatrogenic cost factor of 2.3. Moreover, the study supplied interesting informations about prescriptive habits, which differ in Italy from international guidelines for the medical treatment of OA, about patient management, because of hospitalization, which by itself absorbs 1/3 of resources, and about physiotherapy, which costs twice as much as pharmacological therapy. At last, data analysis gave the cue for suggestions on changing patients’ management.

    2009-04-01

    Due to the emergence of multi-drug resistance, alternatives to conventional antimicrobial therapy are needed. This study aims to investigate the in vitro pharmacological interactions between essential oils (considered valuable as natural therapeutic treatments) and conventional antimicrobials (ciprofloxacin/amphotericin B) when used in combination. Interactions of the essential oils (Melaleuca alternifolia, Thymus vulgaris, Mentha piperita and Rosmarinus officinalis) when combined with ciprofloxacin against Staphylococcus aureus indicate mainly antagonistic profiles. When tested against Klebsiella pneumoniae the isobolograms show antagonistic, synergistic and additive interactions depending on the combined ratio. The R. officinalis/ciprofloxacin combination against K. pneumoniae displayed the most favourable synergistic pattern. The interactions of M. alternifolia (tea tree), T. vulgaris (thyme), M. piperita (peppermint) and R. officinalis (rosemary) essential oils with amphotericin B indicate mainly antagonistic profiles when tested against Candida albicans. While a number of interactions show complete antagonism, others show varied (synergistic, additive and/or antagonistic) interactions, thus the efficacy is dependent on the ratio in which the two components co-exist. The predominant antagonistic interactions noted here, suggests that some natural therapies containing essential oils should be used with caution when combined with antibiotics.

    Full Text Available Objective: To compare the influence of archwire material (NiTi, beta-Ti and stainless steel and brackets design (self-ligating and conventional on the frictional force resistance. Material and Methods: Two types of brackets (self-ligating brackets - Smartclip, 3M/Unitek - and conventional brackets - Gemini, 3M/Unitek with three (0, 5, and 10 degrees slot angulation attached with elastomeric ligatures (TP Orthodontics were tested. All brackets were tested with archwire 0.019"x0.025" nickel-titanium, beta-titanium, and stainless steel (Unitek/3M. The mechanical testing was performed with a universal testing machine eMIC DL 10000 (eMIC Co, Brazil. The wires were pulled from the bracket slots at a cross-head speed of 3 mm/min until 2 mm displacement. Results: Self-ligating brackets produced significantly lower friction values compared with those of conventional brackets. Frictional force resistance values were directly proportional to the increase in the bracket/ wire angulation. With regard to conventional brackets, stainless steel wires had the lowest friction force values, followed by nickel-titanium and beta-titanium ones. With regard to self-ligating brackets, the nickel-titanium wires had the lowest friction values, significantly lower than those of other materials. Conclusion: even at different angulations, the self-ligating brackets showed significantly lower friction force values than the conventional brackets. Combined with nickel-titanium wires, the self-ligating brackets exhibit much lower friction, possibly due to the contact between nickel-titanium clips and wires of the same material.

    2016-05-01

    We present a novel design of a honeycomb lattice geometry that uses a seamless combination of conventional and auxetic cores, i.e. elements showing positive and negative Poisson’s ratio. The design is aimed at tuning and improving the band structure of periodic cellular structures. The proposed cellular configurations show a significantly wide band gap at much lower frequencies compared to their pure counterparts, while still retaining their major dynamic features. Different topologies involving both auxetic inclusions in a conventional lattice and conversely hexagonal cellular inclusions in auxetic butterfly lattices are presented. For all these cases the impact of the varying degree of auxeticity on the band structure is evaluated. The proposed cellular designs may offer significant advantages in tuning high-frequency bandgap behaviour, which is relevant to phononics applications. The configurations shown in this paper may be made iso-volumetric and iso-weight to a given regular hexagonal topology, making possible to adapt the hybrid lattices to existing sandwich structures with fixed dimensions and weights. This work also features a comparative study of the wave speeds corresponding to different configurations vis-a vis those of a regular honeycomb to highlight the superior behaviour of the combined hybrid lattice.

    The focus of the FP7-EU project iSOIL “Interactions between soil related sciences - Linking geophysics, soil science and digital soil mapping” is to develop new and to improve existing strategies and innovative methods for generating accurate, high-resolution soil property maps. Thus we will develop, validate, and evaluate concepts and strategies for transferring measured physical parameter distributions into soil property, soil function and soil threat maps of different scales. The resulting soil property maps can be used for agriculture applications and soil degradation threats studies, e.g. erosion, compaction and soil organic matter decline. A fast and cost efficient way to detect physical parameters of soils at large areas is the application of mobile geophysical platforms. An advantage of these platforms is the flexibility since different kind of instruments can be mounted and combined. Following instruments are used on platforms within iSOIL project: EMI, GPR, gamma-spectrometry and magnetics. Since geophysical methods provide only physical parameters it is essential to combine them with conventional soil sampling methods for ground truthing. Physical parameters have to be converted into soil parameters via (site specific) transfer functions. One focus of the project was the development of measuring designs for the evaluation and combination of different geophysical methods. The application of a hierarchical approach is one way to combine different scales and parameters. The implementation of this approach will be presented and can be summarized as follows: - The first step is a survey of the total area with EMI and gamma-spectrometry. The distance between two lines is 10 - 20 meters. - By means of the geophysical data and a digital elevation model, representative soil sampling points are chosen, via a weighted conditioned latin hypercube sampling scheme (wLHS) based on conditioned latin hypercube sampling (cLHS). - All soil sampling points are probed

    Full Text Available Anaerobic digestion is an important alternative for domestic wastewater treatment, especially in warm climate regions. Two full-scale anaerobic schemes were investigated: septic tank combined with anaerobic filter (S T A NF and conventional UASB reactors. Treated effluents from these systems were subjected to disinfection by chlorination. The operational performance of 56 full-scale plants (36 S T A NF and 20 UASB provided a realistic view. Findings showed that the plants operated with low OLR (< 2.0 kg COD/m³.day. Despite this, the removal of organic material was below values suggested by the literature (around 60% for COD. A removal of 4.0 Log10 units of total coliform and E. coli can be reached with residual chlorine (R CL of at least 2.0 Cl-Cl2/l. Although UASB plants have performed better, improvement of maintenance is needed in both treatment configurations.

  4. Mixing and reaction processes in rocket based combined cycle and conventional rocket engines

    Science.gov (United States)

    Lehman, Matthew Kurt

    Raman spectroscopy was used to make species measurements in two rocket engines. An airbreathing rocket, the rocket based combined cycle (RBCC) engine, and a conventional rocket were investigated. A supersonic rocket plume mixing with subsonic coflowing air characterizes the ejector mode of the RBCC engine. The mixing length required for the air and plume to become homogenous is a critical dimension. For the conventional rocket experiments, a gaseous oxygen/gaseous hydrogen single-element shear coaxial injector was used. Three chamber Mach number conditions, 0.1, 0.2 and 0.3, were chosen to assess the effect of Mach number on mixing. The flow within the chamber was entirely subsonic. For the RBCC experiments, vertical Raman line measurements were made at multiple axial locations downstream from the rocket nozzle plane. Species profiles assessed the mixing progress between the supersonic plume and subsonic air. For the conventional rocket, Raman line measurements were made downstream from the injector face. The goal was to evaluate the effect of increased chamber Mach number on injector mixing/reaction. For both engines, quantitative and qualitative information was collected for computational fluid dynamics (CFD development. The RBCC experiments were conducted for three distinct geometries. The primary flow path was a diffuse and afterburner design with a direct-connect air supply. A sea-level static (SLS) version and a thermally choked variant were also tested. The experimental results show that mixing length increases with additional coflow air in the DAB geometry. Operation of variable rocket mixture ratios at identical air flow rates did not significantly affect the mixing length. The thermally choked variant had a longer mixing length compared to the DAB geometry, and the SLS modification had a shorter mixing length due to a reduced air flow. The conventional rocket studies focused on the effect of chamber Mach number on primary injector mixing. Chamber Mach

    There has been a growing interest in the use of robotic therapy to improve walking ability in individuals following stroke. The aim of this retrospective study was to compare conventional physiotherapy (CP) with robotic training (RT) combined with CP and to measure the effects on gait, balance, functional status, cognitive function, and quality of life in patient with stroke. We retrospectively identified 107 cases of new cerebral stroke. They were allocated into 2 groups. In the RT group (n = 36), patients received RT (Lokomat; 2 times per week) combined with CP (3 times per week) for at least 30 sessions. In the CP group (n = 71), patients received a program at least 30 sessions, 5 times per week. The evaluation parameters included modified Ashworth Spasticity Scale (MASS), Brunnstrom Recovery Scale (BRS), Functional Independence Measure (FIM), Functional Ambulation Categories (FAC), Berg Balance Scale (BBS), Mini-Mental State Examination (MMSE), and Short Form-36 (SF-36) Health Survey. Posttreatment results showed significant improvements for all parameters (except lower extremity MASS scores) in both groups. However, when we compared the percentage changes of parameters at discharge relative to pretreatment values, improvements in FIM, MMSE, and all subparts of SF-36 were better in the RT group (P stroke (up to 1 year) than the CP program.

    Besides x-ray imaging, sonography is the most common method for breast cancer screening. The intention of our work is to develop optoacoustical imaging as an add-on to a conventional system. While ultrasound imaging reveals acoustical properties of tissue, optoacoustics generates an image of the distribution of optical absorption. Hence, it can be a valuable addition to sonography, because acoustical properties of different tissues show only a slight variation whereas the optical properties may differ strongly. Additionally, optoacoustics gives access to physiological parameters, like oxygen saturation of blood. For the presented work, we combine a conventional ultrasound system to a 100 Hz laser. The laser system consists of a Nd:YAG-laser at a wavelength of 532 nm with 7 ns pulse duration, coupled to a tunable Optical Parametric Oscillator (OPO) with a tuning rage from 680 nm to 2500 nm. The tunable laser source allows the selection of wavelengths which compromising high spectral information content with high skin transmission. The laser pulse is delivered fiber-optically to the ultrasound transducer and coupled into the acoustical field of view. Homogeneous illumination is crucial in order to achieve unblurred images. Furthermore the maximum allowed pulse intensities in accordance with standards for medical equipment have to be met to achieve a high signal to noise ration. The ultrasound instrument generates the trigger signal which controls the laser pulsing in order to apply ultrasound instrument's imaging procedures without major modifications to generate an optoacoustic image. Detection of the optoacoustic signal as well as of the classical ultrasound signal is carried out by the standard medical ultrasound transducer. The characterization of the system, including quantitative measurements, performed on tissue phantoms, is presented. These phantoms have been specially designed regarding their acoustical as well as their optical properties.

    This study employed an innovative methodological framework that combines geomatics and conventional survey methods to monitor changes in forest conditions and examine their associations with local forest governance parameters in a mountain watershed covering 153.3 km2 in the middle mountains of Nepal. The study involved two spatial scales and analytical steps. First, geomatics techniques were used to map and detect changes in major land cover types in the watershed between 1976 and 2000 and to analyze relationships between forest cover changes and governance arrangements. This was followed by micro-level analysis of the relationships between the biological conditions of selected forests within the watershed and their governance arrangements, using conventional survey methods and analytical tools. The findings show that forest cover in the watershed increased by about 15 per cent during the period. The rate of increase in forest cover was highest in areas under a semi-government type of governance arrangement, while the community forests were generally better in terms of current biological conditions compared to the semi-government forests. This inconsistency between the findings from the two analyscs does not allow us to draw any firm conclusions regarding the role of property rights in determining forest condition, but it indicates that the outcomes of local forest management initiatives may be more dependent on local institutional arrangements regulating forest use and maintenance of forest resources than on the type of property rights arrangements. The findings also provide evidence of the methodological suitability of the research approach adopted, which may be useful for addressing many other research questions related to forestry and natural resources management, particularly those involving multiple spatial scales.

    Crop varieties with multiple GM events combined by conventional breeding have become important in global agriculture. The regulatory requirements in different countries for such products vary considerably, placing an additional burden on regulatory agencies in countries where the submission of additional data is required and delaying the introduction of innovative products to meet agricultural needs. The process of conventional plant breeding has predictably provided safe food and feed products both historically and in the modern era of plant breeding. Thus, previously approved GM events that have been combined by conventional plant breeding and contain GM traits that are not likely to interact in a manner affecting safety should be considered to be as safe as their conventional counterparts. Such combined GM event crop varieties should require little, if any, additional regulatory data to meet regulatory requirements.

    A solar photo-Fenton process combined with a biological nitrification and denitrification system is proposed for the decontamination of a landfill leachate in a pilot plant using photocatalytic (4.16 m(2) of Compound Parabolic Collectors - CPCs) and biological systems (immobilized biomass reactor). The optimum iron concentration for the photo-Fenton reaction of the leachate is 60 mg Fe(2+) L(-1). The organic carbon degradation follows a first-order reaction kinetics (k = 0.020 L kJ(UV)(-1), r(0) = 12.5 mg kJ(UV)(-1)) with a H(2)O(2) consumption rate of 3.0 mmol H(2)O(2) kJ(UV)(-1). Complete removal of ammonium, nitrates and nitrites of the photo-pre-treated leachate was achieved by biological denitrification and nitrification, after previous neutralization/sedimentation of iron sludge (40 mL of iron sludge per liter of photo-treated leachate after 3 h of sedimentation). The optimum C/N ratio obtained for the denitrification reaction was 2.8 mg CH(3)OH per mg N-NO(3)(-), consuming 7.9 g/8.2 mL of commercial methanol per liter of leachate. The maximum nitrification rate obtained was 68 mg N-NH(4)(+) per day, consuming 33 mmol (1.3 g) of NaOH per liter during nitrification and 27.5 mmol of H(2)SO(4) per liter during denitrification. The optimal phototreatment energy estimated to reach a biodegradable effluent, considering Zahn-Wellens, respirometry and biological oxidation tests, at pilot plant scale, is 29.2 kJ(UV) L(-1) (3.3 h of photo-Fenton at a constant solar UV power of 30 W m(-2)), consuming 90 mM of H(2)O(2) when used in excess, which means almost 57% mineralization of the leachate, 57% reduction of polyphenols concentration and 86% reduction of aromatic content.

    Prominent ears are the most common aesthetic abnormality of the external ear. Mustardè sutures and conchal setback are usually used for otoplasty, additional various cartilage-manipulation methods are also presented. One adjunctive technique that is often used involves the elevation of a fascial flap beneath which is sutured for additional cover, potentially reducing the risk of complications and recurrence. In the literature, this flap is traditionally raised with a proximal or distal base but it can be raised both distally and proximally with a number of advantages as we demonstrate. This article presents a technique to raise the fascioperichondrial flap with both a proximal and a distal base as an addition to conventional otoplasty. One hundred consecutive patients, followed up for at least 12 months, have been reviewed. One hundred ninety otoplasties were performed in 100 patients (10 unilateral), 65 women and 35 men. The mean age was 20.6 years, and the mean follow-up time was 16.3 months, respectively. No patient has developed skin necrosis or suture extrusion. In two patients (One bilateral and one unilateral for a total of three ears) a further procedure has been required to improve symmetry (1.5%). Using the retro auricular fascioperichondrial flap combined with other techniques offers good results and can be used as a standard procedure in the surgical treatment of prominent ears.

    Full Text Available The development of commercially available transfection reagents for gene transfer applications has revolutionized the field of molecular biology and scientific research. However, the challenge remains in ensuring that they are efficient, safe, reproducible and cost effective. Bacteriophage (phage-based viral vectors have the potential to be utilized for general gene transfer applications within research and industry. Yet, they require adaptations in order to enable them to efficiently enter cells and overcome mammalian cellular barriers, as they infect bacteria only; furthermore, limited progress has been made at increasing their efficiency. The production of a novel hybrid nanocomplex system consisting of two different nanomaterial systems, phage vectors and conventional transfection reagents, could overcome these limitations. Here we demonstrate that the combination of cationic lipids, cationic polymers or calcium phosphate with M13 bacteriophage-derived vectors, engineered to carry a mammalian transgene cassette, resulted in increased cellular attachment, entry and improved transgene expression in human cells. Moreover, addition of a targeting ligand into the nanocomplex system, through genetic engineering of the phage capsid further increased gene expression and was effective in a stable cell line generation application. Overall, this new hybrid nanocomplex system (i provides enhanced phage-mediated gene transfer; (ii is applicable for laboratory transfection processes and (iii shows promise within industry for large-scale gene transfer applications.

    The increased sales of organically produced food create a strong need for analytical methods, which could authenticate organic and conventional products. Combined chemometric analysis of (1)H NMR-, (13)C NMR-spectroscopy data, stable-isotope data (IRMS) and α-linolenic acid content (gas chromatography) was used to differentiate organic and conventional milk. In total 85 raw, pasteurized and ultra-heat treated (UHT) milk samples (52 organic and 33 conventional) were collected between August 2013 and May 2014. The carbon isotope ratios of milk protein and milk fat as well as the α-linolenic acid content of these samples were determined. Additionally, the milk fat was analyzed by (1)H and (13)C NMR spectroscopy. The chemometric analysis of combined data (IRMS, GC, NMR) resulted in more precise authentication of German raw and retail milk with a considerably increased classification rate of 95% compared to 81% for NMR and 90% for IRMS using linear discriminate analysis.

    Cerebral palsy leads to many complications as well as delayed motor development, and early intensive rehabilitation in infancy, which is based on the theory of brain plasticity, is emphasized. In addition to conventional treatment, including physical, occupational, or speech-language therapies, children also have a demand for traditional Korean medicine interventions such as acupuncture or herbal medicine; however, a lack of evidence has made traditional Korean medicine difficult to implement in practice. We planned a multicentre, prospective, observational study to assess the effectiveness, safety and cost-effectiveness of conventional treatment and traditional Korean medicine combination treatment for children with cerebral palsy. Three hundred children with cerebral palsy aged 6 to 78 months will be recruited from six institutions. Data from each child are collected every month for a one-year period, during which time treatment might be changed or discontinued. A qualified investigator visits the sites to measure effectiveness variables, including Gross Motor Function Measure and Paediatric Evaluation of Disability Inventory. Adverse events and cost-effectiveness variables are collected using surveys conducted at baseline, mid-study, and end of study, as well as monthly tracking surveys. In the analyses, participants will be classified into two groups: group A children will be the conventional treatment group with physical, occupational, speech-language or other conventional rehabilitation therapies, whereas group B children will be the combination treatment group with traditional Korean medicine interventions, that is, herbal medicine, chuna, moxibustion and acupuncture, in addition to conventional treatment. Only a few clinical case reports have evaluated the effectiveness and safety of traditional Korean medicine; therefore, more data are required to provide optimal information to children with cerebral palsy and their guardians. We hypothesized that

    Aim: To evaluate the treatment of male infertility with a strong natural antioxidant, in addition to conventional treatment.Methods: Using a double blind, randomized trial design, 30 men with infertility of ≥12 months and female partners with no demonstrable cause of infertility received conventional treatment according to the guidelines of the World Health Organization (WHO), and either a strong antioxidant Astaxanthin 16 mg/day (AstaCarox(R), AstaReal AB,Gustavsberg, Sweden) or placebo for 3 months. The effects of treatment on semen parameters, reactive oxygen species (ROS), zona-free hamster oocyte test, serum hormones including testosterone, luteinizing hormone (LH),follicle stimulating hormone (FSH) and Inhibin B, and spontaneous or intrauterine insemination (IUI)-induced pregnancies were evaluated. Results: ROS and Inhibin B decreased significantly and sperm linear velocity increased in the Astaxanthin group (n = 11), but not in the placebo group (n = 19). The results of the zona-free hamster oocyte test tended to improve in the Astaxanthin group in contrast with the placebo group, though not reaching statistical significance.The total and per cycle pregnancy rates among the placebo cases (10.5 % and 3.6 %) were lower compared with 54.5 % and 23.1% respectively in the Astaxanthin group (P = 0.028; P = 0.036). Conclusion: Although the present study suggests a positive effect of Astaxanthin on sperm parameters and fertility, the results need to be confirmed in a larger trial before recommending Astaxanthin for the complementary treatment of infertile men.

    Spice extracts under the form of essential oils (Eos) were tested for their efficiency to increase the relative bacterial radiosensitivity (RBR) of Listeria monocytogenes, Escherichia coli and Salmonellatyphi in culture media under different atmospheric conditions. The selected Eos were tested for their ability to reduce the dose necessary to eliminate E. coli and S.typhi in medium fat ground beef (23% fat) and Listeria in ready-to-eat carrots when packed under air or under atmosphere rich in oxygen (MAP). Results have demonstrated that depending of the compound added and the combined treatment used, the RBR increased from 2 to 4 times. In order to evaluate the industrial feasibility, EOs were added in ground beef at a concentration which does not affect the taste and treated at a dose of 1.5 kGy. The content of total mesophilic aerobic, E. coli, Salmonella, total coliform, lactic acid bacteria, and Pseudomonas was determined during 28 days. The results showed that the combined treatment (radiation and EOs) can eliminate Salmonella and E. coli when done under air. When done under MAP, Pseudomonas could be eliminated and a shelf life of more than 28 days was observed. An active edible coating containing EOs was also developed and sprayed on ready-to-eat carrots before radiation treatment and Listeria was evaluated. A complete inhibition of Listeria was obtained at a dose of 0.5 kGy when applied under MAP. Our results have shown that the combination of an edible coating, MAP, and radiation can be used to maintain the safety of meat and vegetables.

    Cancer is a problem of global importance, since the incidence is increasing worldwide and therapeutic options are generally limited. Thus, it becomes imperative to find new therapeutic targets as well as new molecules with therapeutic potential for tumors. Flavonoids are polyphenolic compounds that may be potential therapeutic agents. Several studies have shown that these compounds have a higher anticancer potential. Among the flavonoids in the human diet, quercetin is one of the most important. In the last decades, several anticancer properties of quercetin have been described, such as cell signaling, pro-apoptotic, anti-proliferative and anti-oxidant effects, growth suppression. In fact, it is now well known that quercetin has diverse biological effects, inhibiting multiple enzymes involved in cell proliferation, as well as, in signal transduction pathways. On the other hand, there are also studies reporting potential synergistic effects when combined quercetin with chemotherapeutic agents or radiotherapy. In fact, several studies which aim to explore the anticancer potential of these combined treatments have already been published, the majority with promising results. Actually it is well known that quercetin can act on the chemosensitization and radiosensitization but also as chemoprotective and radioprotective, protecting normal cells of the side effects that results from chemotherapy and radiotherapy, which obviously provides notable advantages in their use in anticancer treatment. Thus, all these data indicate that quercetin may have a key role in anticancer treatment. In this context, this review is focused on the relationship between flavonoids and cancer, with special emphasis on the role of quercetin.

    Laboratory-scale experiments were conducted in order to investigate the effect of ozone as pre-aerobic treatment and post-aerobic treatment for the treatment of the distillery wastewater. The degradation of the pollutants present in distillery spent wash was carried out by ozonation, aerobic biological degradation processes alone and by using the combinations of these two processes to investigate the synergism between the two modes of wastewater treatment and with the aim of reducing the overall treatment costs. Pollutant removal efficiency was followed by means of global parameters directly related to the concentration of organic compounds in those effluents: chemical oxygen demand (COD) and the color removal efficiency in terms of absorbance of the sample at 254 nm. Ozone was found to be effective in bringing down the COD (up to 27%) during the pretreatment step itself. In the combined process, pretreatment of the effluent led to enhanced rates of subsequent biological oxidation step, almost 2.5 times increase in the initial oxidation rate has been observed. Post-aerobic treatment with ozone led to further removal of COD along with the complete discoloration of the effluent. The integrated process (ozone-aerobic oxidation-ozone) achieved approximately 79% COD reduction along with discoloration of the effluent sample as compared to 34.9% COD reduction for non-ozonated sample, over a similar treatment period.

    Electric stimulation (E-stim) has been found to be an effective treatment in improving wound healing rates. However, the wound healing trajectory and its related predictors for complete wound closure (CWC) have not been reported with E-stim treatment. This was a retrospective study. Data on 159 patients treated at an outpatient wound clinic utilizing combined intervention of E-stim and conventional care were included. The Kaplan-Meier healing curve together with linear regression models depicted the percentage of patients with CWC against time. With 100, 112 and 140 days of treatment, the percentages of patients with CWC were 59·12%, 61·01% and 65·41%, respectively. Linear regression models predicted that all patients would achieve CWC by 21·55, 22·26 and 24·80 weeks, respectively. The speed for the increase in the number and percentage of patients with CWC peaked between 50-75 days of treatment. To optimize timely healing, referral to other treatment facilities or change of treatment protocol is warranted around the peak time. With the combined intervention of E-stim and conventional care, positive predictors for CWC included a shorter wound duration at initial evaluation (P = 0·005, OR = 3·10), better compliance with appointments (P = 0·007, OR = 3·38) and the diagnosis of venous leg ulcer (P = 0·001, OR = 3·88). This study provided preliminary data on wound healing trajectory and predictors with combined E-stim and conventional care. E-stim seemed to expedite wound healing; however, further research studies are needed. © 2016 Stichting European Society for Clinical Investigation Journal Foundation.

    Conventional sanitary landfill leachate treatment has recently been complemented and, in some cases, completely replaced by reverse osmosis technology. Despite the good quality of treated water, the efficiency of the process is low and a large volume of reverse osmosis concentrate has to be either discharged or further treated. In this study, the use of anodic oxidation combined with electro-Fenton processes to treat the concentrate obtained in the reverse osmosis of sanitary landfill leachate was evaluated. The anodic oxidation pretreatment was performed in a pilot plant using an electrochemical cell with boron-doped diamond electrodes. In the electro-Fenton experiments, a boron-doped diamond anode and carbon-felt cathode were used, and the influence of the initial pH and iron concentration were studied. For the experimental conditions, the electro-Fenton assays performed at an initial pH of 3 had higher organic load removal levels, whereas the best nitrogen removal was attained when the electrochemical process was performed at the natural pH of 8.8. The increase in the iron concentration had an adverse impact on treatment under natural pH conditions, but it enhanced the nitrogen removal in the electro-Fenton assays performed at an initial pH of 3. The combined anodic oxidation and electro-Fenton process is useful for treating the reverse osmosis concentrate because it is effective at removing the organic load and nitrogen-containing species. Additionally, this process potentiates the increase in the biodegradability index of the treated effluent.

    Clinical and experimental data suggest a synergistic antitumoral effect with the combined treatment of radiotherapy and 5-fluorouracil (5-FU) serving as a radiosensitizer. This combined modality was studied in 30 malignant melanoma patients with advanced locoregional or isolated, bulky, soft-tissue or visceral metastases. All patients were symptomatic, pain being the chief complaint, followed by symptoms related to large tumors. Treatment was given on an ambulatory basis, twice weekly, and consisted of 5-FU, 500 mg/m2 administered in 8-h i.v. drip infusion, followed by radiotherapy 8 h after completion of the 5-FU administration. /sup 60/Co teleunit, delivering 400 rad per dose per fraction, was given over 6 1/2 weeks to a total of 5,200 rad. The overall response rate was 70% (21 of 30 patients). Three patients (10%) achieved a complete response lasting from 3 to 11 months, and 18 (60%) achieved a partial response lasting from 3 to 13 months. The response rate was 82% for skin, 75% for lymph node, and 43% for visceral metastases. Symptomatic relief was obtained in 83% (25 of 30) of the patients. This palliative therapy was well-tolerated, and patients were able to maintain their routine lifestyles throughout. Only in one patient was 5-FU abandoned after 3 weeks, due to cardiac ischemia. Similar response rates have only been achieved with radiotherapy alone employing individual fractions of 600 rad or higher. Since the 5-FU we added is known to have a very limited effect on malignant melanoma, this study suggests its potential as a radiosensitizer in malignant melanoma.

    A preliminary study to combine electron beam irradiation process with biological treatment was carried out. Experiments were conducted using samples from a governmental wastewater treatment plant (WTP) that receives about 20% of industrial wastewater, with the objective of destroying the refractory organic pollutants and to obtain a better performance of this plant. Samples from five different steps of WTP were collected and irradiated in the electron beam accelerator in a batch system with 5.0, 10.0 and 20.0 kGy doses. The main results showed a removal of 99% of all organic compound analysed in the industrial receiver unit (IRU) effluent and in the coarse bar screen (CBS) effluent with a 20 kGy dose, and for the medium bar screen (MBS) and primary sedimentation (PS) effluent a 10 kGy dose was sufficient. In the case of final effluent (FE), a dose of 5 kGy removed the remaining organic compounds and dyes present after biological treatment.

    Full Text Available In high temperature reactors including gas cooled fast reactors and gas turbine modular helium reactors (GT-MHR specifically designed to operate as power plant heat sources, efficiency enhancement at effective cost under safe conditions can be achieved. Mentioned improvements concern the implementation of two cycle structures: (a, a stand alone Brayton operating with helium and a stand alone Rankine cycle (RC with regeneration, operating with carbon dioxide at ultrasupercritical pressure as working fluid (WF, where condensation is carried out at quasicritical conditions, and (b, a combined cycle (CC, in which the topping closed Brayton cycle (CBC operates with helium as WF, while the bottoming RC is operated with one of the following WFs: carbon dioxide, xenon, ethane, ammonia, or water. In both cases, an intermediate heat exchanger (IHE is proposed to provide thermal energy to the closed Brayton or to the Rankine cycles. The results of the case study show that the thermal efficiency, through the use of a CC, is slightly improved (from 45.79% for BC and from 50.17% for RC to 53.63 for the proposed CC with He-H2O operating under safety standards.

    Full Text Available ABSTRACT Objective: To compare the effects of either a carbohydrate-restrictive diets or a conventional hypoenergetic diet combined with resistance training. Methods: Twenty-one overweight and obese adults participated in an eight-week program consisting of progressive resistance training combined with carbohydrate-restrictive diets (initially set at <30 g carbohydrate; n=12 or conventional hypoenergetic diet (30% energetic restriction; carbohydrate/protein/lipid: 51/18/31% of total energy consumption; n=9. It was hypothesized that the carbohydrate-restrictive diets would induce greater weight loss but that both diets would elicit similar effects on selected health markers. Body mass, and body composition, blood variables and flow-mediated brachial artery dilation (flow-mediated brachial artery dilation; by ultrasound were used to assess changes due to the interventions. Results: Significant within-group reductions in body mass (-5.4±3.5%; p=0.001 versus -3.7±3.0%; p=0.015 and body fat (body fat; -10.2±7.0%; p=0.005 versus -9.6±8.8%; p=0.017 were identified for carbohydrate-restrictive diets and conventional hypoenergetic diet, respectively, but there were no significant differences between groups as the result of the interventions. Fat free mass, blood variables and flow-mediated brachial artery dilation did not significantly change, except for the total cholesterol/high-density lipoprotein ratio, which was reduced 10.4±16.9% in carbohydrate-restrictive diets (p=0.037 and 0.5±11.3% in conventional hypoenergetic diet (p=0.398. Conclusion: Carbohydrate-restrictive diets associated with resistance training was as effective as conventional hypoenergetic diet in decreasing body mass and body fat, as well as maintaining fat free mass, blood variables and flow-mediated brachial artery dilation, however it was more effective at lowering the total cholesterol/low density lipoprotein ratio.

    Campylobacter spp. are important causes of bacterial zoonosis, most often transmitted by contaminated poultry meat. From an epidemiological and risk assessment perspective, further knowledge should be obtained on Campylobacter prevalence and genotype distribution in primary production. Consequently, 15 Austrian broiler flocks were surveyed in summer for their thermophilic Campylobacter spp. contamination status. Chicken droppings, dust and drinking water samples were collected from each flock at three separate sampling periods. Isolates were confirmed by PCR and subtyped. We also compared three alternative methods (culture-based enrichment in Bolton broth, culture-independent real-time PCR and a lateral-flow test) for their applicability in chicken droppings. Twelve flocks were found to be positive for thermophilic Campylobacter spp. during the entire sampling period. Seven flocks (46.6%) were contaminated with both, C. jejuni and C. coli, five flocks harboured solely one species. We observed to a majority flock-specific C. jejuni and C. coli genotypes, which dominated the respective flock. Flocks within a distance jejuni genotypes indicating a cross-contamination event via the environment or personnel vectors. Multilocus sequence typing (MLST) of C. jejuni revealed that the majority of isolates were assigned to globally distributed clonal complexes or had a strong link to the human interface (CC ST-446 and ST4373). The combination of techniques poses an advantage over risk assessment studies based on cultures alone, as, in the case of Campylobacter, occurrence of a high variety of genotypes might be present among a broiler flock. We suggest applying the lateral-flow test under field conditions to identify 'high-shedding' broiler flocks at the farm level. Consequently, poultry farmers and veterinarians could improve hygiene measurements and direct sanitation activities, especially during the thinning period. Ultimately, real-time PCR could be applied to quantify

    Background and Objective. Anxiety/pain are experiences that make dental treatment difficult for children, especially during the time of anesthesia. Hypnosis is used in pediatric clinical situations to modify thinking, behavior, and perception as well as, recently, in dentistry; therefore the aim of this study was to evaluate the effectiveness of hypnosis combined with conventional behavior management techniques during infiltration anesthetic. Methods. Anxiety/pain were assessed with the FLACC scale during the anesthetic moment, as well as heart rate variability and skin conductance before and during the anesthetic moment, between the control and experimental group. Results. A marginal statistical difference (p = 0.05) was found in the heart rate between baseline and anesthetic moment, being lower in the hypnosis group. No statistically significant differences were found with the FLACC scale or in the skin conductance (p > 0.05). Conclusion. Hypnosis combined with conventional behavior management techniques decreases heart rate during anesthetic infiltration showing that there may be an improvement in anxiety/pain control through hypnotic therapy.

    Browning reactions in fruits and vegetables are a serious problem for the food industry. In mushrooms, the principal enzyme responsible for the browning reaction is polyphenoloxidase (PPO). Microwaves have recently been introduced as an alternative for the industrial blanching of mushrooms. However, the direct application of microwave energy to entire mushrooms is limited by the important temperature gradients generated within the samples during heating, which can produce internal water vaporization and associated damage to the mushrooms texture. A microwave applicator has been developed, whereby irradiation conditions can be regulated and the heating process monitored. Whole edible mushrooms (Agaricus bisporus) were blanched by conventional, microwave, and combined heating methods to optimize the rate of PPO inactivation. A combined microwave and hot-water bath treatment has achieved complete PPO inactivation in a short time. Both the loss of antioxidant content and the increase of browning were minor in the samples treated with this combined method when compared to the control. This reduction in processing time also decreased mushroom weight loss and shrinkage.

    Tracer testing is a well-established technique in hydrogeological site characterization. However, certain a priori knowledge of the hydraulic regime is required beforehand to avoid test failure, e.g. miss of tracer. In this study, we propose a novel tracer test concept for the hydraulic characterization of shallow unconsolidated sedimentary deposits when only scarce a priori information on the hydraulic regime is available. Therefore, we combine conventional salt tracer testing with direct push vertical high resolution electrical conductivity logging. The proposed tracer test concept was successfully tested on coarse, braided river deposits of the Tagliamento River, Italy. With limited a priori information available two tracer tests were performed in three days to reliably determine ground water flow direction and velocity allowing on-site decision-making to adaptively install observation wells for reliable breakthrough curve measurements. Furthermore, direct push vertical electrical profiling provided essential information about the plume characteristics with outstanding measurement resolution and efficiency.

    Full Text Available The paper deals with the selection of materials for the sea¬ling layer in the final cover of sanitary landfills. The sealing la¬yer is the most critical component of the final cover. Its role is to minimize percolation of water through the final cover. Ma¬terials used for the construction of the sealing layer are either of mineral origin (compacted clay or geosynthetic (geomem¬brane. They are most often used in combination creating com¬posite liners. Recently alternative materials are also used like paper mill sludge or discarded swelling clay.

    In cases of disputed paternity, the scientific goal is to promote either the exclusion of a falsely accused man or the affiliation of the alleged father. Until now, in addition to anthropologic characteristics, the determination of genetic markers included human leukocyte antigen gene variants; erythrocyte antigens and serum proteins were used for that reason. Recombinant DNA techniques provided a new set of highly variable genetic markers based on DNA nucleotide sequence polymorphism. From the practical standpoint, the application of these techniques to paternity testing provides greater versatility than do conventional genetic marker systems. The use of methods to detect the polymorphism of human leukocyte antigen loci significantly increases the chance of validation of ambiguous results in paternity testing. The outcome of 2384 paternity cases investigated by serologic and/or DNA-based human leukocyte antigen typing was statistically analyzed. Different cases solved by DNA typing are presented involving cases with one or two accused men, exclusions and nonexclusions, and tests of the paternity of a deceased man. The results provide evidence for the advantage of the combined application of various techniques in forensic diagnostics and emphasizes the outstanding possibilities of DNA-based assays. Representative examples demonstrate the strength of combined techniques in paternity testing.

    The present study was performed to improve early lung cancer diagnosis in bronchial washing fluid, thereby increasing the diagnostic sensitivity of bronchoscopy by means of high-resolution flow cytometry (FC). We combined dual-parameter DNA/protein FC and conventional cytology in bronchial washing fluid samples from 112 patients with neoplastic and non-neoplastic lung diseases and found 43% of histologically confirmed tumor cases to be cytologically positive; 63% of the tumor samples were aneuploid, 52% of the aneuploid cases were cytologically positive and 48% were negative. In the negative cases, FC was an independent diagnostic factor. In 32% of the cases, FC also failed to detect abnormalities. However, the combination of both techniques increased the sensitivity in detecting neoplastic cells to 73%. Furthermore, simultaneous DNA/protein analysis allowed the recognition of aneuploid cell lines not detectable by single DNA measurement. Identification of aneuploid subpopulations by dual-parameter analysis in cytologically negative one-parameter FC "diploid" samples assumes an important diagnostic value. Dual-parameter DNA/protein FC is a valuable technique that increases the diagnostic yield of bronchoscopy with no risk for the patient and a low additional cost.

    Highlights: • We assessed in ALS the diagnostic accuracy of MRI signal and MRS data used alone and in combination. • We found that T2-hypointensity and NAA decrease in motor cortex are two independent phenomena. • These two variables taken alone do not provide acceptable diagnostic accuracy in ALS. • The same variables, when used in combination, improve the diagnostic accuracy of MRI in ALS. - Abstract: Purpose: We aimed to assess, in amyotrophic lateral sclerosis (ALS), the diagnostic accuracy of the combined use of conventional MRI signal changes (namely, hypointensity of the precentral cortex and hyperintensity of the corticospinal tracts on T2-weighted images), and N-Acetyl-Aspartate (NAA) reduction in the motor cortex at Magnetic Resonance Spectroscopy (MRS), which are affected by limited diagnostic accuracy when used separately. Methods: T2-hypointensity and NAA/(Choline + Creatine) ratio of the precentral gyrus and T2-hyperintensity of the corticospinal tracts were measured in 84 ALS patients and 28 healthy controls, using a Region-of-Interest approach. Sensitivity and specificity values were calculated using Fisher stepwise discriminant analysis, and cross-validated using the leave-one-out method. Results: Precentral gyrus T2 signal intensity (p < 10{sup −4}) and NAA peak (p < 10{sup −6}) were significantly reduced in patients, and their values did not correlate significantly to each other both in patients and controls, while no significant differences were obtained in terms of T2-hyperintensity of the corticospinal tract. Sensitivity and specificity of the two discriminant variables, taken alone, were 71.4% and 75.0%, for NAA peak, and 63.1% and 71.4% for T2-hypointensity, respectively. When using these two variables in combination, a significant increase in sensitivity (78.6%) and specificity (82.1%) was achieved. Conclusions: Precentral gyrus T2-hypointensity and NAA peak are not significantly correlated in ALS patients, suggesting that they

    Military architecture heritage is frequently built on rock masses affected by slope instability and weathering processes, which progressively undermine the foundations and cause collapses and toppling of the masonries. The latter can be also weakened by alteration of the stone surfaces, as a consequence of the interactions with the local environmental conditions. These conservation issues are emphasized for those sites, whose susceptibility to structural damages is also due to the similarity between the lithotypes constituting the geologic substratum and the construction materials. Effective solutions for the protection from such a type of phenomena can be achieved if the whole "rock mass - built heritage system" is analyzed. In this perspective, we propose a new approach for the study of the weathering processes affecting historic hilltop sites, taking benefits from the combination of terrestrial laser scanning (TLS) and conventional investigations, the latter including geotechnical and minero-petrographic analyses. In particular, the results here presented were obtained from specific tests on the fortifications of Citadel, Gozo (Malta), performed in co-operation with the Restoration Unit, Works Division, Maltese Ministry for Resources and Rural Affairs and the private company Politecnica Ingegneria e Architettura. The Citadel fortifications are built at the top of a relatively stiff and brittle limestone plate, formed by Upper Coralline Limestone (UCL) and overlying a thick Blue Clay (BC) layer. Differential weathering creates extensively fractured ledges on the cap and erosion niches in the strata beneath, thereby favouring block detachment, even rockfall events, such as the last one occurred in 2001. The locally quarried Globigerina Limestone (GL), historically employed in restoration masonries, is also exposed to alveolization and powdering, and several collapses damaged the underwalling interventions. Since the erosion pattern distribution suggested a

    Treatment with nonsteroidal antiinflammatory drugs (NSAID) is the recommended first-line therapy in patients with axial spondyloarthritis (axSpA); and for those patients who have persistently active disease, the introduction of tumor necrosis factor-α (TNF-α) inhibitors is indicated. Conventional nonbiological disease-modifying antirheumatic drugs (DMARD), although effective and used in clinical practice for peripheral arthritis, are not recommended. Few studies have been conducted with the aim of evaluating the effect of conventional DMARD, either alone or in combination, in axSpA. As for psoriatic arthritis (PsA), DMARD are widely used, but few trials are available about their effects on axial involvement, which is not often assessed as a primary outcome in clinical trials. In rheumatoid arthritis, combination therapy of 2 or more conventional DMARD appears to confer better response than methotrexate monotherapy, and may even be a viable alternative to TNF-α inhibitors. In peripheral PsA, combination therapy can be used after treatment failure with 1 DMARD, but few studies have been conducted. However, available evidence for the combination of conventional DMARD indicates a lack of any significant benefit on axial symptoms; thus this treatment approach does not represent an effective alternative to anti-TNF-α therapy.

    Many European countries tend to shift from constructing combined sewer systems to separate ones, in order to optimise wastewater treatment efficiency and reduce CSO impact on surface waters. An economic design minimises maintenance requirements by aiming at self-cleansing pipes. However, providing the necessary slopes for self-cleansing sanitary sewer pipes often is unfeasible in flat regions, resulting in an increased risk of loss of hydraulic capacity or blocking. To reduce these risks, flushing tanks can be installed in the sewer system. Where most other researchers contribute to a better understanding of the hydraulics of flushing, this paper rather tries to formulate a methodology to design and test flushing devices in sanitary sewer systems using standards and hydrodynamic simulations. Therefore, several aspects that require consideration when incorporating flushing devices into a sanitary sewer system are discussed. For instance, when flushing sanitary sewers the increase in discharge has to be explicitly considered. A Belgian case study is used to investigate the suitability of the developed methodology. Although the pipe slopes in the methodology are derived assuming uniform flow, the simulation results comply with it. Furthermore, pressurisation of the conduits due to multiple flushing waves remains within acceptable limits.

    Objective: To evaluate the clinical efficacy of dendritic cell-activated cytokine-induced killer (DC-CIK) cells combined with conventional therapy in the treatment of malignant tumors. Methods: A total of 100 patients with malignant tumors were randomly divided into two groups. Treatment group received conventional therapy combined with DC-CIK while control group received conventional therapy alone. The short-term efficacy, adverse reactions and changes of lymphocyte subpopulation were all compared between two groups after treatment. Results: The overall response rate (ORR) was higher in treatment group (86.00%) than in control group (54.00%), the difference was statistically significant (P0.05). WBC reduced markedly, but the level of alanine aminotransferase (ALT) increased obviously after treatment in control group (P0.05). In treatment group, the levels of CD3+, CD3+CD4+, CD3+CD8+, and CD3+CD56+ increased (P0.05). In control group, the levels of CD3+ and CD3+CD4+ reduced (P0.05). The levels of CD3+, CD3+CD4+, CD3+CD8+and CD3+CD56+ in treatment group were higher than those in control group (P Conclusion:DC-CIK combined with conventional therapy, safe and effective, is capable of promoting the recovery of leukocytes and liver and kidney function, and improving the cellular immune function, which may provide a new therapeutic regimen for patients with malignant tumors.

    Concurrent panic disorder with agoraphobia (PDA) and generalized anxiety disorder (GAD) are the most common diagnostic occurrences among anxiety disorders. This particular comorbidity is associated with significant impairments in quality of life (QOL). The current study sought to investigate the efficacy of a combined cognitive-behavioral psychotherapy that addressed both conditions compared with a conventional psychotherapy, which attends solely to the primary disorder. The hypotheses postulated firstly, that both treatment conditions would lead to improvements in participants' QOL and secondly, that the combined therapy would lead to greater QOL ameliorations. Twenty-five participants with comorbid PDA/GAD diagnoses were evaluated with a number of clinical interviews and self-report questionnaires, and were provided with either conventional or combined cognitive-behavioral psychotherapy, which consisted of 14 one-hour weekly sessions. Participants were once again evaluated in the same fashion 2-weeks after the completion of the psychotherapy. The results revealed that both conditions led to significant improvements in participants' QOL, but that the two groups did not significantly differ in terms of the effect on QOL. The results also reveal that the two conditions did not significantly differ in terms of their effect on PDA and GAD symptomatology or psychiatric comorbidity. The results demonstrate that the combined psychotherapy, which addresses both conditions simultaneously, is similar to the conventional psychotherapy employed for the primary disorder in terms of QOL enhancement, symptom severity, and comorbidity reduction.

    This prospective study was to compare the image quality and diagnostic performance of breast cystic masses by conventional and advanced ultrasound (US) techniques including tissue harmonic, compound, and the combination of these techniques. All 91 patients, collectively having 109 breast cystic masses were scanned using four US techniques (complicated cysts in 36, septated cysts in 33, and complex cysts in 40). Two breast radiologists independently assessed the image quality and possibility of malignancy. Image quality was evaluated in terms of contrast and clarity of the wall and internal echo pattern and then graded on a scale of 1 (poor) to grade 3 (satisfactory). The possibility of malignancy was graded on a scale of 1 (suggestive of benignancy) to 5 (suggestive of malignancy) using US images. The histopathological results and follow-up images were used as the reference standard for the assessment of diagnostic performance. Results were evaluated by Friedman's test and receiver operating characteristic (ROC) analyses. In terms of image quality, a grade of 3 was significantly more frequent in the three advanced US techniques than conventional US (p < 0.05). For assessment of diagnostic performance, areas under the ROC curves in three advanced techniques were significantly higher than in conventional US (p < 0.05). Advanced US techniques including compound and tissue harmonic US techniques provide a better image quality in breast cystic masses and also improve the diagnostic performance compared with conventional US

    The exploitation of deep geothermal resources for energy production relies on finding cost effective solutions to increase the drilling performance in hard rocks. Conventional rotary drilling techniques, based on mechanical rock exportation, result in high rates of drilling tool wearing, causing significant costs. Additionally, rotary drilling results in low drilling speeds in the typically hard crystalline basement rocks targeted for enhanced geothermal energy utilization technologies. Furthermore, even lower overall drilling rates result, when considering tripping times required to exchange worn drill tools. Therefore, alternative drilling techniques, such as hammering, thermal drilling, plasma drilling, and jetting processes are widely investigated in order to provide cost-effective alternatives to conventional drilling methods. A promising approach, that combines conventional rotary and thermal drilling techniques, is investigated in the present work. Here, the rock material is thermally weakened before being exported by conventional cutters. Heat is locally provided by a flame, which moves over the rock surface, heat-treating the material. Besides reducing the rock strength, an in-depth smoothening effect of the mechanical rock properties is observed due to the thermal treatment. This results in reduced rates of drill bit wearing and higher rates of penetration, which in turn decreases drilling costs significantly, particularly for deep-drilling projects. Due to the high heating rates, rock-hardening, commonly observed at moderate temperatures, can be avoided. The flame action can be modelled as a localized, high heat transfer coefficient flame treatment, which results in orders of magnitude higher heating rates than conventional oven treatments. Therefore, we analyse rock strength variations after different maximum temperatures, flame-based heating rates, and rock confinement pressures. The results show that flame treatments lead to a monotonous decrease of

    Element load, conventional biomarkers and altered protein expression profiles were studied in Carcinus maenas crabs, to assess contamination of 'Domingo Rubio' stream, an aquatic ecosystem that receives pyritic metals, industrial contaminants, and pesticides. Lower antioxidative activities - glucose-6-phosphate and 6-phosphogluconate dehydrogenases, catalase - were found in parallel to higher levels of damaged biomolecules - malondialdehyde, oxidized glutathione -, due to oxidative lesions promoted by contaminants, as the increased levels of essential - Zn, Cu, Co - and nonessential - Cr, Ni, Cd - elements. Utility of Proteomics to assess environmental quality was confirmed, especially after considering the six proteins identified by de novo sequencing through capLC-muESI-ITMS/MS and homology search on databases. They include tripartite motif-containing protein 11 and ATF7 transcription factor (upregulated), plus CBR-NHR-218 nuclear hormone receptor, two components of the ABC transporters and aldehyde dehydrogenase (downregulated). These proteins could be used as novel potential biomarkers of the deleterious effects of pollutants present in the area. - Pollution assessment at 'Domingo Rubio' stream (Spain).

    The objective of this study was to compare the quality of legume cakes baked in microwave-infrared combination (MW-IR) oven with conventional oven. Legume cake formulations were developed by replacing 10 % wheat flour by lentil, chickpea and pea flour. As a control, wheat flour containing cakes were used. Weight loss, specific volume, texture, color, gelatinization degree, macro and micro-structure of cakes were investigated. MW-IR baked cakes had higher specific volume, weight loss and crust color change and lower hardness values than conventionally baked cakes. Larger pores were observed in MW-IR baked cakes according to scanning electron microscope (SEM) images. Pea flour giving the hardest structure, lowest specific volume and gelatinization degree was determined to be the least acceptable legume flour. On the other hand, lentil and chickpea flour containing cakes had the softest structure and highest specific volume showing that lentil and chickpea flour can be used to produce functional cakes.

    Regional differences in practices, ethnicity, and climate may influence the skin compatibility of sanitary pads. Although several clinical trials have been performed in North America, Mexico, Western Europe, Eastern Europe, and Africa, there is no clinical study reported for Asia. The purpose of this study was to examine the skin compatibility of two types of modern sanitary pads in Chinese women along with a dermatological assessment and their satisfaction and preference. The self-feeling and safety of a new sanitary pad with a non-woven top specially-shaped surface sheet was tested and compared with a conventional sanitary pad with a perforated film top sheet. The subjects studied were 22 Chinese women (age: 20-50 years) with a history of mild and occasional sanitary pad dermatitis residing in Shanghai. One subject wished to discontinue the trial for personal reasons, thus 21 subjects completed the trial. These subjects were randomly assigned to two types of sanitary pads, and used one type during their next menstrual period, and another type during their following menstrual period. After each menstrual period, a dermatologist examined the objective and subjective skin symptoms and determined a score. The subjects were asked to rate their level of satisfaction with respect to overall usability, softness, stickiness, dryness, and absorbency, and to choose which pad they had preferred. No adverse effect was observed for either type of pad. Edema, erythema, burning, and stinging were not obvious symptoms for either type of pad. For itching, 30-65% of the subjects scored slight or mild for both types of pads. A comprehensive evaluation showed that several symptoms were observed on both type of pads at slight and mild levels, but minimal and insignificant differences were found between them. The majority of subjects were highly satisfied with both types, but preferred the new sanitary pad with a non-woven specially-shaped surface top sheet for its softness and

    Conventional roentgenograms of 25 patients who underwent combined aortic and mitral valve replacement were evaluated and correlated with pre- and postoperative functional and haemodynamic parameters. The roentgenograms were obtained 6 months before and up to 24 months after valve replacement. A reduction in heart size could be seen in nearly all patients. This was independent of clinical and haemodynamic results. An increase in heart size always suggests severe haemodynamic worsening, especially a paravalvular leakage. The most valuable X-ray sign is the degree of pulmonary congestion, which is well correlated with the cardiac index.

  16. Ammonia nitrogen desorption from sanitary landfill leachate in filling towers

    Sanitary landfill leachates present high concentrations of carbonaceous and nitrogenous materials. The crucial point is that carbonaceous materials are of difficult biodegradation, what compromises the performance of biological treatment processes, while nitrogenous materials, such as ammonia nitrogen, probably preclude the use of biological treatments. Therefore, the aim of this work was to study the desorption process of ammonia nitrogen from sanitary landfill leachate in filling towers. De...

    Full Text Available The electrochemical treatment of leachate samples from a Portuguese intermunicipal sanitary landfill was carried out using anodic oxidation. The treatment was performed in a pilot plant that possesses an electrochemical cell, with boron-doped diamond electrodes, working in batch mode with recirculation. The influence of the applied current density and the flow rate on the performance of the electrochemical oxidation was investigated. Current density was decreased by steps, during the degradation, in order to study this effect on the efficiency of the process. For the assays run at equal flow rate and initial current intensity, chemical oxygen demand (COD removal seems to depend mainly on the charge passed and the variation of the current density during the anodic oxidation process can reduce the energetic costs. An increase in the recirculation flow rate leads to an increase in the organic load removal rate and a consequent decrease in the energetic costs, but it decreases the nitrogen removal rate. Also, the bias between dissolved organic carbon and COD removals increases with flow rate, indicating that an increase in recirculation flow rate decreases the mineralization index.

  19. Combination of Conventional and Advanced DInSAR to Monitor Very Fast Mining Subsidence with TerraSAR-X Data: Bytom City (Poland

    2015-04-01

    Full Text Available In this work, the analysis of TerraSAR-X satellite images combining both conventional and advanced Differential Synthetic Aperture Radar Interferometry (DInSAR approaches has proven to be effective to detect and monitor fast evolving mining subsidence on urban areas in the Upper Silesian Coal Basin (Poland. This region accounts for almost three million inhabitants where mining subsidence has produced severe damage to urban structures and infrastructures in recent years. Conventional DInSAR approach was used to generate 28 differential interferograms between 5 July 2011 and 21 June 2012 identifying 31 subsidence troughs that account up to 245 mm of displacement in 54 days (equivalent to 1660 mm/year. SqueeSARTM processing yielded a very dense measurement point distribution, failing to detect faster displacements than 330 mm/year, which occur within the subsidence troughs detected with conventional DInSAR. Despite this limitation, this approach was useful to delimit stable areas where mining activities are not conducted and areas affected by residual subsidence surrounding the detected subsidence troughs. These residual subsidence mining areas are located approximately 1 km away from the 31 detected subsidence troughs and account for a subsidence rate greater than 17 mm/year on average. The validation of this methodology has been performed over Bytom City were underground mining activity produced severe damages in August 2011. Conventional DInSAR permitted to successfully map subsidence troughs between July and August 2011 that coincide spatially and temporally with the evolution of underground mining excavations, as well as with the demolition of 28 buildings of Karb district. Additionally, SqueeSARTM displacement estimates were useful to delimit an area of 8.3 km2 of Bytom city that is affected by a residual mining subsidence greater than 5 mm/year and could potentially suffer damages in the midterm.

    Purpose: To evaluate the efficacy of pulsed low-dose radiation therapy (PLRT) combined with temozolomide (TMZ) as a novel treatment approach for radioresistant glioblastoma multiforme (GBM) in a murine model. Methods and Materials: Orthotopic U87MG hGBM tumors were established in Nu-Foxn1{sup nu} mice and imaged weekly using a small-animal micropositron emission tomography (PET)/computed tomography (CT) system. Tumor volume was determined from contrast-enhanced microCT images and tumor metabolic activity (SUVmax) from the F18-FDG microPET scan. Tumors were irradiated 7 to 10 days after implantation with a total dose of 14 Gy in 7 consecutive days. The daily treatment was given as a single continuous 2-Gy dose (RT) or 10 pulses of 0.2 Gy using an interpulse interval of 3 minutes (PLRT). TMZ (10 mg/kg) was given daily by oral gavage 1 hour before RT. Tumor vascularity and normal brain damage were assessed by immunohistochemistry. Results: Radiation therapy with TMZ resulted in a significant 3- to 4-week tumor growth delay compared with controls, with PLRT+TMZ the most effective. PLRT+TMZ resulted in a larger decline in SUVmax than RT+TMZ. Significant differences in survival were evident. Treatment after PLRT+TMZ was associated with increased vascularization compared with RT+TMZ. Significantly fewer degenerating neurons were seen in normal brain after PLRT+TMZ compared with RT+TMZ. Conclusions: PLRT+TMZ produced superior tumor growth delay and less normal brain damage when compared with RT+TMZ. The differential effect of PLRT on vascularization may confirm new treatment avenues for GBM.

    B-cell chronic lymphocytic leukemia (CLL) is characterized by an accumulation in peripheral blood of many long-lived lymphocytes that do not die because of the deregulation of apoptosis. Most CLL cells are quiescent, and therefore the leukemic lymphocytes are resistant to conventional chemotherapy. The aim of this study was to evaluate in vitro the chemosensitivity of CLL cells to cladribine or fludarabine used alone or in combinations with mafosfamide (Mf; the active form of cyclophosphamide) as well as to roscovitine, a potent inhibitor of cyclin-dependent kinases with proapoptotic potential. The results of flow cytometry revealed that tested agents differentially reduced the viability of leukemic cells. Interestingly, roscovitine exerts a similar cytotoxic effect as the combinations of the used purine analogs with Mf, but with other kinetics. Roscovitine kills leukemic cells after a much shorter exposure time. Immunoblotting analysis showed that the reduction of the number of living cells coincides with marked changes of the balance between pro- and antiapoptotic factors. The latter were markedly reduced. The activation of proapoptotic proteins became evident especially after exposure of cells to roscovitine alone or to combinations of purine analogs and Mf. Furthermore, exposure of CLL cells to tested drugs degraded p27(KIP1) protein. Our findings demonstrate that roscovitine alone significantly reduces the number of viable CLL cells by inducing them to undergo apoptosis, and it acts earlier than clinically applied combinations of purine analogs with Mf/cyclophosphamide. These results confirm the high efficacy of roscovitine against CLL cells.

    Surface deformation caused by an intrusion and small eruption during June 17-19, 2007, along the East Rift Zone of Kilauea Volcano, Hawaii, was three-dimensionally reconstructed from radar interferograms acquired by the Advanced Land Observing Satellite (ALOS) phased-array type L-band synthetic aperture radar (SAR) (PALSAR) instrument. To retrieve the 3-D surface deformation, a method that combines multiple-aperture interferometry (MAI) and conventional interferometric SAR (InSAR) techniques was applied to one ascending and one descending ALOS PALSAR interferometric pair. The maximum displacements as a result of the intrusion and eruption are about 0.8, 2, and 0.7 m in the east, north, and up components, respectively. The radar-measured 3-D surface deformation agrees with GPS data from 24 sites on the volcano, and the root-mean-square errors in the east, north, and up components of the displacement are 1.6, 3.6, and 2.1 cm, respectively. Since a horizontal deformation of more than 1 m was dominantly in the north-northwest-south-southeast direction, a significant improvement of the north-south component measurement was achieved by the inclusion of MAI measurements that can reach a standard deviation of 3.6 cm. A 3-D deformation reconstruction through the combination of conventional InSAR and MAI will allow for better modeling, and hence, a more comprehensive understanding, of the source geometry associated with volcanic, seismic, and other processes that are manifested by surface deformation.

    SPECT myocardial perfusion imaging (MPI) is a clinical mainstay that is typically performed with static imaging protocols and visually or semi-quantitatively assessed for perfusion defects based upon the relative intensity of myocardial regions. Dynamic cardiac SPECT presents a new imaging technique based on time-varying information of radiotracer distribution, which permits the evaluation of regional myocardial blood flow (MBF) and coronary flow reserve (CFR). In this work, a preliminary feasibility study was conducted in a small patient sample designed to implement a unique combined static-dynamic single-dose one-day visit imaging protocol to compare quantitative dynamic SPECT with static conventional SPECT for improving the diagnosis of coronary artery disease (CAD). Fifteen patients (11 males, four females, mean age 71 ± 9 years) were enrolled for a combined dynamic and static SPECT (Infinia Hawkeye 4, GE Healthcare) imaging protocol with a single dose of (99m)Tc-tetrofosmin administered at rest and a single dose administered at stress in a one-day visit. Out of 15 patients, eleven had selective coronary angiography (SCA), 8 within 6 months and the rest within 24 months of SPECT imaging, without intervening symptoms or interventions. The extent and severity of perfusion defects in each myocardial region was graded visually. Dynamically acquired data were also used to estimate the MBF and CFR. Both visually graded images and estimated CFR were tested against SCA as a reference to evaluate the validity of the methods. Overall, conventional static SPECT was normal in ten patients and abnormal in five patients, dynamic SPECT was normal in 12 patients and abnormal in three patients, and CFR from dynamic SPECT was normal in nine patients and abnormal in six patients. Among those 11 patients with SCA, conventional SPECT was normal in 5, 3 with documented CAD on SCA with an overall accuracy of 64%, sensitivity of 40% and specificity of 83%. Dynamic SPECT image

    In this paper are discussed essential issues about the concept, characteristics and general functions of sanitary regulation, as well as the principles and main lines of action contained in the Program of Modernization of the Sanitary Regulation, which is being implemented by the Ministry of Health of Mexico. In addition, some considerations are offered regarding the supporting role of such a program, in the context of the free trade era that Mexico is undergoing. After 40 years of an outdated sanitary regulation based in a non-functional licensing concept, the new and improved scheme relies on several ammendments to the General Health Law. Thus, the present approach, focuses on a set of flexible, simple and efficient rules, strengthened by proven scientific and technical procedures.

    To explore the correlations of conventional MRI (cMRI) and diffusion tensor imaging (DTI) values with the 1p/19 codeletion and IDH mutations in oligodendroglial tumours (OTs). Eighty-four patients with OTs who underwent cMRI and DTI were retrospectively reviewed. The maximal fractional anisotropy and minimal apparent diffusion coefficient (ADC) were measured and compared using the Mann-Whitney U test. Receiver operating characteristic curves, logistic regression analysis and four-table statistics analysis were performed to predict genotypings. OTs with 1p/19q codeletion or IDH mutations were prone to locate in frontal (P = 0.106 and 0.005, respectively) and insular lobes and were associated with absent or blurry contrast enhancement (P = 0.040 and 0.013, respectively). DTI values showed significant differences between OTs with and without IDH mutations (P < 0.05) but not in OTs with and without 1p/19q loss. The Ki-67 index significantly correlated with IDH mutations (P = 0.002) but not with 1p/19q codeletion. A combination of DTI and cMRI for the identification of IDH mutations resulted in sensitivity, specificity, positive and negative predictive values of 92.2 %, 75.8 %, 93.8 % and 71.1 %, respectively. Combination of DTI and cMRI correlates with isocitrate dehydrogenase 1/2 mutations but not 1p/19q genotyping in OTs. (orig.)

    Full Text Available The reduction of brain amyloid beta (Aβ peptides by anti-Aβ antibodies is one of the possible therapies for Alzheimer’s disease. We previously reported that the Aβ peptide vaccine including the T-cell epitope of diphtheria-tetanus combined toxoid (DT induced anti-Aβ antibodies, and the prior immunization with conventional DT vaccine enhanced the immunogenicity of the peptide. Cynomolgus monkeys were given the peptide vaccine subcutaneously in combination with the prior DT vaccination. Vaccination with a similar regimen was also performed on guinea pigs. The peptide vaccine induced anti-Aβ antibodies in cynomolgus monkeys and guinea pigs without chemical adjuvants, and excessive immune responses were not observed. Those antibodies could preferentially recognize Aβ40, and Aβ42 compared to Aβ fibrils. The levels of serum anti-Aβ antibodies and plasma Aβ peptides increased in both animals and decreased the brain Aβ40 level of guinea pigs. The peptide vaccine could induce a similar binding profile of anti-Aβ antibodies in cynomolgus monkeys and guinea pigs. The peptide vaccination could be expected to reduce the brain Aβ peptides and their toxic effects via clearance of Aβ peptides by generated antibodies.

    Creation of optimal sanitary - hygienic conditions allows to keep health and capacity of the crewmembers work at increase of space flight duration. There is a wide application experience of means, methods and equipment for sanitary - hygienic supply, which were developed and experimentally tested for space flights. However, about 800 kg personal hygiene means (napkins and towels are made with water and delivered with the Earth) are necessary for 3 crewmembers per one year. For long orbital and interplanetary flights (without an opportunity of stocks updating) it is necessary to increase a degree of Life-Support System isolation and optimization of goods turnover. Washing combined with water regeneration system is most perspective for sanitary - hygienic procedures. Therefore, creation of space equipment for washing with sanitary - hygienic water (SHW) regeneration system is especially important. The researches have shown, that to processes, which can be applied for SHW regeneration in space conditions and require insignificant quantity of additional materials (as against sorption), concern membrane methods (reverse osmosis, nanofiltration etc.). Two-step membrane unit for SHW regeneration recovered no less than 85 % of permeate with the organic and inorganic selectivity of 82-95 %. The tests of two-step membrane unit for SHW regeneration carried out on mock up solutions and real SHW, containing detergents really used in space flight conditions. The researches on a substantiation of an opportunity of clothing washing, clothing drying and the estimation of an opportunity of application of various detergents for clothing washing are urgent. The tests of water extraction technology from textile materials are carried out. Is established, that at conditional time of contact 1s, humidity of a leaving air flow from clothing drying unit comes nearer to 100 %. It is necessary to solve the problem for creation of Life-Support System of new generation for long-term space

    Oxidative stress has been described as a key pathway to initiate mercury (Hg) toxicity in fish. However, the mechanisms underlying Hg-induced oxidative stress in fish still need to be clarified. To this aim, environmental metabolomics in combination with a battery of conventional oxidative stress biomarkers were applied to the gills of golden grey mullet (Liza aurata) collected from Largo do Laranjo (LAR), a confined Hg contaminated area, and São Jacinto (SJ), selected as reference site (Aveiro Lagoon, Portugal). Higher accumulation of inorganic Hg and methylmercury was found in gills of fish from LAR relative to SJ. Nuclear magnetic resonance (NMR)-based metabolomics revealed changes in metabolites related to antioxidant protection, namely depletion of reduced glutathione (GSH) and its constituent amino acids, glutamate and glycine. The interference of Hg with the antioxidant protection of gills was corroborated through oxidative stress endpoints, namely the depletion of glutathione peroxidase and superoxide dismutase activities at LAR. The increase of total glutathione content (reduced glutathione+oxidized glutathione) at LAR, in parallel with GSH depletion aforementioned, indicates the occurrence of massive GSH oxidation under Hg stress, and an inability to carry out its regeneration (glutathione reductase activity was unaltered) or de novo synthesis. Nevertheless, the results suggest the occurrence of alternative mechanisms for preventing lipid peroxidative damage, which may be associated with the enhancement of membrane stabilization/repair processes resulting from depletion in the precursors of phosphatidylcholine (phosphocholine and glycerophosphocholine), as highlighted by NMR spectroscopy. However, the observed decrease in taurine may be attributable to alterations in the structure of cell membranes or interference in osmoregulatory processes. Overall, the novel concurrent use of metabolomics and conventional oxidative stress endpoints demonstrated to be

    Oxidative stress has been described as a key pathway to initiate mercury (Hg) toxicity in fish. However, the mechanisms underlying Hg-induced oxidative stress in fish still need to be clarified. To this aim, environmental metabolomics in combination with a battery of conventional oxidative stress biomarkers were applied to the gills of golden grey mullet (Liza aurata) collected from Largo do Laranjo (LAR), a confined Hg contaminated area, and São Jacinto (SJ), selected as reference site (Aveiro Lagoon, Portugal). Higher accumulation of inorganic Hg and methylmercury was found in gills of fish from LAR relative to SJ. Nuclear magnetic resonance (NMR)-based metabolomics revealed changes in metabolites related to antioxidant protection, namely depletion of reduced glutathione (GSH) and its constituent amino acids, glutamate and glycine. The interference of Hg with the antioxidant protection of gills was corroborated through oxidative stress endpoints, namely the depletion of glutathione peroxidase and superoxide dismutase activities at LAR. The increase of total glutathione content (reduced glutathione + oxidized glutathione) at LAR, in parallel with GSH depletion aforementioned, indicates the occurrence of massive GSH oxidation under Hg stress, and an inability to carry out its regeneration (glutathione reductase activity was unaltered) or de novo synthesis. Nevertheless, the results suggest the occurrence of alternative mechanisms for preventing lipid peroxidative damage, which may be associated with the enhancement of membrane stabilization/repair processes resulting from depletion in the precursors of phosphatidylcholine (phosphocholine and glycerophosphocholine), as highlighted by NMR spectroscopy. However, the observed decrease in taurine may be attributable to alterations in the structure of cell membranes or interference in osmoregulatory processes. Overall, the novel concurrent use of metabolomics and conventional oxidative stress endpoints demonstrated to

    The scientific rationale for preventive measures based on sanitary-and-epidemiological surveillance on environmental objects is considered. The sizes of functional zones and space for various types of communal services and amenities and leisure are regulated to ensure good urban vital activities. Multistorey housing causes an increase in the number of negative factors per area units and in their impact on health. A proposal has been made for the standardization of the ranges of urban population upsurge and size, by using the sanitary-and-hygienic rules and norms rather than climatic parameters. A criterion system for assessing the data of statistical observations has been substantiated and 5 levels of analysis and managerial decision-making have been proposed. Cause-and-effect relations may be determined for the parameters of the second level; models of program-oriented studies for the third level, only sanitary-and-epidemiological surveillance is possible for the fourth and fifth levels. The space planning scheme must provide for water supply reserves, generation areas for pure air coming into the town, and waste disposal areas. The general layout may use statistical observation parameters characterizing the second level of occurrence of negative phenomena. The statistical observation parameters characterizing the third and fourth levels of occurrence of negative phenomena may be used for municipal improvements and sanitary maintenance. These characterizing the fourth and fifth level may be used for prevention in therapeutic-and-prophylactic institutions.

    Full Text Available In the article the short historical review on the design of sanitary rooms and their configurations is given. The main errors of the recent years, which led to the decrease in accommodation convenience because of the wrong approach from both the architect and engineers, are given. It is possible to use a small useful area for sanitary facilities, but it is connected with the lack of possibility of connecting washing and dishwashers. The author considers the options of engineering equipment placement in sanitary rooms taking into account the convenience of use, safety, and also resource-saving aspect. Various solutions on the organization of heating and ventilation are provided. The possible technical solutions allowing solving a flooding problem of the first floors in elite housing estates in case of accident are offered with the help of full waterproofing of sanitary rooms, and also the whole area of the apartment. The main attention was focused on the improvements of sanitary rooms for one-room and two-room apartments, which are the most demanded in the modern market of real estate. Layout solutions of the reduced bathrooms on the placement of the necessary equipment with choice justification are provided. The attention is paid to the layout solution for modern kitchens on order to increase their comfort by the use of special two-section sinks, and also a grinder of food waste in order to allow to lower the load of the systems of rubbish disposal of a building, by dumping the crushed garbage in an internal sewer network. Various options of evolutionary development of sanitary rooms for increasing the comfort degree are given. First of all, the development should happen in the direction of not only sanitation and hygiene, but also of the maintenance of the physical health of the people living in the building. It can be carried out by increase in a useful area of sanitary rooms, installation of exercise machines, medical bathtubs and a Jacuzzi

    The process of investigating paintings includes the identification of materials to solve technical and historical art questions, to aid in the deduction of the original appearance, and in the establishment of the chemical and physical conditions for adequate restoration and conservation. In particular, we have focused on the identification of several samples taken from six famous canvases painted by Pedro Atanasio Bocanegra, who created a very special collection depicting the life of San Ignacio, which is located in the church of San Justo y Pastor of Granada, Spain. The characterization of the inorganic and organic compounds of the textiles, preparation layers, and pictorial layers have been carried out using an XRD diffractometer, SEM observations, EDX spectrometry, FT-IR spectrometry (both in reflection and transmission mode), pyrolysis/gas chromatography/mass spectrometry and synchrotron-based micro-X-ray techniques. In this work, the advantages over conventional X-ray diffraction of using combined synchrotron-based micro-X-ray diffraction and micro-X-ray fluorescence in the identification of multi-layer paintings is demonstrated.

    It has been established that disturbances in intracellular signaling pathways play a considerable part in the oncologic process. Phosphatidylinositol-3-kinase (PI3K) has become of key interest in cancer therapy because of its high mutation frequency and/or gain in function of its catalytic subunits in cancer cells. We investigated the therapeutic value of BYL719, a new specific PI3Kα inhibitor that blocks the ATP site, on osteosarcoma and bone cells. The in vitro effects of BYL719 on proliferation, apoptosis, and cell cycle were assessed in human and murine osteosarcoma cell. Its impact on bone cells was determined using human mesenchymal stem cells (hMSC) and human CD14+ osteoclast precursors. Two different murine preclinical models of osteosarcoma were used to analyze the in vivo biological activities of BYL719. BYL719 decreased cell proliferation by blocking cell cycle in G0/G1 phase with no outstanding effects on apoptosis cell death in HOS and MOS-J tumor cells. BYL719 inhibited cell migration and can thus be considered as a cytostatic drug for osteosarcoma. In murine preclinical models of osteosarcoma, BYL719 significantly decreased tumor progression and tumor ectopic bone formation as shown by a decrease of Ki67+ cells and tumor vascularization. To explore the maximum therapeutic potential of BYL719, the drug was studied in combination with conventional chemotherapeutic drugs, revealing promising efficacy with ifosfamide. BYL719 also exhibited dual activities on osteoblast and osteoclast differentiation. Overall, the present work shows that BYL719 is a promising drug in either a single or multidrug approach to curing bone sarcoma. © 2014 UICC.

    Sweet basil, Ocimum basilicum, is one of the most important and wildly used spices and has been shown to have antioxidant, antibacterial, and anti-diarrheal activities. In this study, high performance liquid chromatographic (HPLC) and flow-injection mass spectrometric (FIMS) fingerprinting techniques were used to differentiate organic and conventional sweet basil leaf samples. Principal component analysis (PCA) of the fingerprints indicated that both HPLC and FIMS fingerprints could effectively detect the chemical differences in the organic and conventional sweet basil leaf samples. This study suggested that the organic basil sample contained greater concentrations of almost all the major compounds than its conventional counterpart on a per same botanical weight basis. The FIMS method was able to rapidly differentiate the organic and conventional sweet basil leaf samples (1min analysis time), whereas the HPLC fingerprints provided more information about the chemical composition of the basil samples with a longer analytical time.

    2010-11-01

    This paper analyzes the Brazilian Sanitary Surveillance System as an arrangement aimed at regulating and reducing health risks associated with consumption of products, use of health services and the environment. Historical, political and tax aspects were considered and their development compared with the National Health Surveillance System, which has received strong international cooperation. The comparison was based on the trajectory of their national systems and related federal agencies, as well as on criteria adopted for decentralization. The central category of analysis is federative coordination and was based on the framework of federalism and intergovernmental relations. The institutional context of health and sanitary surveillance presents strong political competition, instability in the project and probable reduction of the ability of federal coordination after the Pact for Health. The National Sanitary Surveillance System due to its nature of public good and high externality in its field of action requires federal coordination for increasing the regional and local cooperation, also because of the structural heterogeneity of Brazilian municipalities.

    Highlights: • Photoelectrooxidation (PEO) emerges as a new technology for leachate treatment. • Aging of sanitary landfills acts on leachate composition and biodegradability. • PEO is applied as leachate pretreatment before the biological processes. • PEO produced significant changes in the leachate matrix, easing biological process. - Abstract: The sanitary landfill leachate is a dark liquid, of highly variable composition, with recalcitrant features that hamper conventional biological treatment. The physical–chemical characteristics of the leachate along the landfill aging, as well as their effects on the efficiency of the conventional treatment, were evaluated at this paper. The feasibility of photoelectrooxidation process as an alternative technique for treatment of landfill leachates was also determined. Photoelectrooxidation experiments were conducted in a bench-scale reactor. Analysis of the raw leachate revealed many critical parameters demonstrating that the recalcitrance of leachate tends to increase with time, directly influencing the decline in efficiency of the conventional treatment currently employed. The effects of current density and lamp power were investigated. Using a 400 W power lamp and a current density of 31.5 mA cm{sup −2}, 53% and 61% efficiency for the removal of ammoniacal nitrogen and chemical oxygen demand were respectively achieved by applying photoelectrooxidation process. With the removal of these pollutants, downstream biological treatment should be improved. These results demonstrate that photoelectrooxidation is a feasible technique for the treatment of sanitary landfill leachate, even considering this effluent’s high resistance to treatment.

    This study investigated the effect of a low-viscosity adhesive resin (Icon) applied after either hydrochloric (HCl) or phosphoric acid (H3PO4) on the adhesion of metal brackets to enamel. Failure types were analyzed. The crowns of bovine incisors (N = 20) were sectioned mesio-distally and inciso-gingivally, then randomly assigned to 4 groups according to the following protocols to receive mandibular incisor brackets: 1) H3PO4 (37%)+TransbondXT (3M UNITEK); 2) H3PO4 (37%)+Icon+TransbondXT; 3) HCl (15%)+Icon (DMG)+TransbondXT 4) HCl (15%)+Icon+Heliobond (Ivoclar Vivadent)+TransbondXT. Specimens were stored in distilled water at 37°C for 24 h and thermocycled (5000x, 5°C to 55°C). The shear bond strength (SBS) test was performed using a universal testing machine (1 mm/min). Failure types were classified according to the Adhesive Remnant Index (ARI). Contact angles of adhesive resins were measured (n = 5 per adhesive) on ceramic surfaces. No significant difference in SBS was observed, implying no difference between combinations of adhesive resins and etching agents (p = 0.712; ANOVA). The Weibull distribution presented significantly lower Weibull modulus (m) of group 3 (m = 2.97) compared to other groups (m = 5.2 to 6.6) (p group 1 (45.4 ± 7.9) > group 2 (44.2 ± 10.6) > group 3 (42.6 ± 15.5). While in groups 1, 3, and 4 exclusively an ARI score of 0 (no adhesive left on tooth) was observed, in group 2, only one specimen demonstrated score 1 (less than half of adhesive left on tooth). Contact angle measurements were as follows: Icon (25.86 ± 3.81 degrees), Heliobond (31.98 ± 3.17 degrees), TransbondXT (35 ± 2.21 degrees). Icon can be safely used with the conventional adhesives tested on surfaces etched with either HCl or H3PO4.

    The first formally adopted regulatory policy for irradiation as a phyto sanitary treatment in the United States was issued in 1989 and was based on Title 7 of the Code of Federal Regulations. These regulations authorized irradiation as a quarantine treatment for papayas intended for movement from the State of Hawaii to the continental United States (U.S.), Guam, Puerto Rico, and the U.S. Virgin Islands. This authorization was specific for commodity, place of origin, and program, but was designed for a complex of three fruit flies rather than a single pest. Routine commercial shipments were never realized under this regulation due to the lack of a treatment facility in Hawaii. However, the authorization has proven useful from the standpoint of beginning to establish policies for irradiation as a phyto sanitary treatment in the United States. The United States Department of Agriculture (USDA), Animal and Plant Health Inspection Service (APHIS), Plant Protection and Quarantine (PPQ) remains dedicated to using the most up-to-date, appropriate and least intrusive technology to provide quarantine security. The need for alternative treatments for pests mitigation systems is greater than ever. Global trade pressures and the possible loss of methyl bromide make it imperative that all practical treatment options be explored. Since 1989 irradiation treatment concepts have matured significantly. Technological advances, greater experience, and an increasingly larger body of research indicate that irradiation has important potential as a treatment for quarantine pest problems. It is in this light that PPQ is expanding its regulatory framework, is addressing irradiation treatment options, and is developing comprehensive policy statements intended to facilitate the development and formalization of new treatments for phyto sanitary applications.

    Landfilling is a major option in waste management hierarchy in developing nations. It generates leachate, which has the potential of polluting watercourses. This study analysed the physico-chemical components of leachate from a closed sanitary landfill in Malaysia, in relation to evaluating the toxicological impact on fish species namely Pangasius sutchi S., 1878 and Clarias batrachus L., 1758. The leachate samples were taken from Air Hitam Sanitary Landfill (AHSL) and the static method of acute toxicity testing was experimented on both fish species at different leachate concentrations. Each fish had an average of 1.3 ± 0.2 g wet weight and length of 5.0 ± 0.1 cm. Histology of the fishes was examined by analysing the gills of the response (dead) group, using the Harris haemtoxylin and eosin (H&E) method. Finneys' Probit method was utilized as a statistical tool to evaluate the data from the fish test. The physico-chemical analysis of the leachate recorded pH 8.2 ± 0.3, biochemical oxygen demand 3500 ± 125 mg L(-1), COD 10 234 ± 175 mg L(-1), ammonical nitrogen of 880 ± 74 mg L(-1), benzene 0.22 ± 0.1 mg L(-1) and toluene 1.2 ± 0.4 mg L(-1). The 50% lethality concentration (LC(50)) values calculated after 96 h exposure were 3.2% (v/v) and 5.9% (v/v) of raw leachate on P. sutchi and C. batrachus, respectively. The H&E staining showed denaturation of the nucleus and cytoplasm of the gills of the response groups. Leachate from the sanitary landfill was toxic to both fish species. The P. sutchi and C. batrachus may be used as indicator organisms for leachate pollution in water.

    The Mexican Electricity Utility (Comision Federal de Electricidad - CFE) growing program in Power Generation for the 2004 - 2008 period is based on Combined Cycle Power Plants (CCPP). In accordance with [CFE, 2000], the expected power generation capacity developed during such period will rise by the amount of 12876 MW, 10655 MW belonging to CCPP (82.75 %). With such important program for the increasing of Power Generation in Mexico, researches have to receive new technologies for CCPP, some of them not completely tested and immature, with the compromise to make then more efficient and reliable. Under such idea and looking to increase the automation level for CCPP with better control algorithms, the Supervisory Generalized Control (SGC) for CCPP was developed in this thesis, based on PID strategies and intelligent (fuzzy) control strategies. With the SGC is possible to get the best performance for the whole CCPP through the automatic starting, synchronizing and loading of the generating units (two gas turbines and one steam turbine) with a minimum participation of operators. To get the increased efficiency, the SGC generates the reference paths for both gas turbines (GT) first, and the steam turbine (ST). The SGC accelerates each unit with a minimum effort and vibrations getting the synchronizing speed in a minimum time and wasted energy. Then the SGC synchronize each unit taking minimum load quickly and loading up to the highest electric power value. All these can be done in an automated operation. The SGC employs two critical-process variable- control strategies, based on blade path temperature average (BPT Average) for Gas Turbines (GT) and the throttle steam pressure for the Steam Turbine (ST).

    Purpose: Evaluation of vertebroplasty using a combination of CT-fluoroscopy and conventional lateral fluoroscopy in patients with osteoporotic vertebral fractures. Materials and Methods: Fifty-eight patients (23male, 35 women, age 69.7 {+-} 10.2 years) with painful osteoporotic vertebral fractures were treated with vertebroplasty in conscious sedation and local anesthesia. Spiral-CT with sagittal reconstructions of the respective vertebral bodies was used for classification of the fracture. The cannula was placed under CT-guidance in the ventral third of the respective vertebral bodies and cement instilled under CT fluoroscopy and lateral fluoroscopy. When cement migrated towards the vertebral canal, the injection was immediately stopped for 30-60 seconds. After polymerization in this location, the injection was continued until sufficient filling of the vertebra. Results were documented by spiral CT with sagittal reconstructions. Results: A total of 123 vertebral bodies were treated, comprising 39 thoracic and 84 lumbar vertebral bodies, with a mean of 2.1 {+-} 1.3 (range 1 to 6) vertebral bodies in each patient and a maximum of 3 vertebral bodies per session. All interventions were successfully completed in conscious sedation and local anesthesia. A mean volume of 5.9 {+-} 0.6 ml (range 2 to 14 ml) cement was applied for each vertebra, with 79.7% of procedures performed using a unilateral access. To achieve a sufficient cement deposit, a bilateral access was used in 20.3%. The dorsal wall of the vertebra was included in 23.6% of the fractures. In one case, cement migration into the spinal canal was detected, reducing the diameter of the canal by 30%. In two other cases, cement leakage was seen at the puncture site of the vertebra (one intercostotransversally in the 10{sup th} thoracic vertebra and one dorsolaterally in the 1{sup st} lumbar vertebra) with retrograde cement migration through the neuroforamen into the epidural space. In one of these cases, the

    Eight wells of the LFW series monitor groundwater quality in the Steed Pond Aquifer (Water Table) beneath the Interim Sanitary Landfill at the Savannah River Site. These wells are sampled semiannually to comply with the South Carolina Department of Health and Environmental Control Modified Municipal Solid Waste Permit 025500-1120 and as part of the SRS Groundwater Monitoring Program. Trichlorofluoromethane and 1,1,1-trichloroethane were elevated in one sidegradient well and one downgradient well during 1996. Zinc was elevated in three downgradient wells and also was detected in the associated laboratory blanks for two of those wells. Specific conductance was elevated in one background well and one sidegradient well. Barium and copper exceeded standards in one sidegradient well, and dichloromethane (a common laboratory contaminant) was elevated in another sidegradient well. Barium, copper, and dichloromethane were detected in the associated blanks for these wells, also. The groundwater flow direction in the Steed Pond Acquifer (Water Table) beneath the Interim Sanitary Landfill was to the southeast (universal transverse Mercator coordinates). The flow rate in this unit was approximately 210 ft/year during first quarter 1996 and 180 ft/yr during third quarter 1996.

    Purpose: Dual-energy CT (DECT) affords quantitative information of tissue density and provides a new dimension for disease diagnosis and treatment planning. The technique, however, increases the imaging dose because of the doubled scans, and thus hinders its widespread clinical applications. The purpose of this work is to develop a novel hybrid DECT image acquisition and reconstruction strategy, in which one of the energies is dealt by interior tomography while the other one is obtained using conventional tomography approach. Methods: In the proposed hybrid imaging strategy, the projection data of one of the energies (e.g., high-energy) were acquired and processed in an interior scanning model, whereas the other energy in the conventional tomographic approach. It known that, if the ROI is piecewise constant or polynomial, the interior ROI can be reconstructed with TV or HOT minimization. Here we extend the TV based interior reconstruction method into dual-energy situation. The ROI images so obtained were overlaid in the context of conventional CT of the companion energy. A material based composition in ROI was used in the proposed reconstruction framework. Results: In the simulation experiment with a diagnostic DECT geometry and energies, we were able to derive the densities of soft-tissues and bones in the ROI with high fidelity. In the experimental CBCT study, both kV and MV data were collected using the on-board kV and MV imaging system. The MV data were truncated only across the ROI. Using the interior tomography reconstruction above, we were able to obtain the ROI images as that obtained using un-truncated MV data with known tissue densities. Conclusion: The proposed DECT imaging strategy provides an effective way to extract tissue density information in the ROI and in the context of anatomical images of CT imaging, with much reduced imaging dose.

    Full Text Available Background: The aim of the present study was to evaluate and compare the conventional (macro-surgical and microsurgical approach in performing the free rotated papilla autograft combined with coronally advanced flap surgery in treatment of localized gingival recession. Materials and Methods: A total of 20 sites from 10 systemically healthy patients were selected for the study. The selected sites were randomly divided into experimental site A and experimental site B by using the spilt mouth design. Conventional (macro-surgical approach for site A and micro-surgery for site B was applied in performing the free rotated papilla autograft combined with coronally advanced flap. Recession depth (RD, recession width (RW clinical attachment level (CAL. and width of keratinized tissue (WKT. were recorded at baseline, 3 months and 6 months post-operatively. Results: Both (macro- and microsurgery groups showed significant clinical improvement in all the parameters (RD, RW, CAL and WKT. However, on comparing both the groups, these parameters did not reach statistical significance. Conclusion: Both the surgical procedures were equally effective in treatment of localized gingival recession by the free rotated papilla autograft technique combined with coronally advanced flap. However, surgery under magnification (microsurgery may be clinically better than conventional surgery in terms of less post-operative pain and discomfort experienced by patients at the microsurgical site.

    The aim of this study was to assess the antihypertensive efficacy and safety of aliskiren versus ramipril or losartan in hypertensive patients with type 2 diabetes mellitus, microalbuminuria and uncontrolled hypertension, despite the use of optimal conventional antihypertensive therapy. In this open-label active comparator study, 126 patients were randomly assigned to receive 24 weeks of additional therapy with aliskiren (Group A) or either losartan or ramipril (Group B), according to whether a patient was already treated with an angiotensin-converting enzyme inhibitor or an angiotensin receptor blocker, respectively. After 24 weeks, both treatment groups experienced a significant reduction of systolic blood pressure (-11.37% and -8.47%, respectively; both p <0.001 vs. baseline) and diastolic blood pressure levels (-10.67% and -9.28%, respectively; both p <0.001 vs. baseline), with a greater reduction of mean systolic values in Group A compared with Group B (p <0.001). Furthermore, after six months microalbuminuria was significantly decreased in both treatment groups (-67.62% and -49.1%, respectively; both p <0.001), with a reduction rate in Group A significantly higher than in Group B (p<0.001). The addition of aliskiren to optimal conventional therapy provided a higher reduction of blood pressure and urinary albumin excretion when compared with the addition of losartan or ramipril. © The Author(s) 2014.

    The behavior along the potabilization process of 29 pharmaceuticals and 12 drugs of abuse identified from a total of 81 compounds at the intake of a drinking water treatment plant (DWTP) has been studied. The DWTP has a common treatment consisting of dioxychlorination, coagulation/flocculation and sand filtration and then water is splitted in two parallel treatment lines: conventional (ozonation and carbon filtration) and advanced (ultrafiltration and reverse osmosis) to be further blended, chlorinated and distributed. Full removals were reached for most of the compounds. Iopromide (up to 17.2 ng/L), nicotine (13.7 ng/L), benzoylecgonine (1.9 ng/L), cotinine (3.6 ng/L), acetaminophen (15.6 ng/L), erythromycin (2.0 ng/L) and caffeine (6.0 ng/L) with elimination efficiencies {>=}94%, were the sole compounds found in the treated water. The advanced treatment process showed a slightly better efficiency than the conventional treatment to eliminate pharmaceuticals and drugs of abuse. - Highlights: > The presence of pharmaceuticals and drugs of abuse in surface water was demonstrated. > Elimination in both potabilization processes reached levels >99% for most compounds. > Four pharmaceuticals and three drugs of abuse survived the potabilization process. - The efficiency of potabilization processes to eliminate or transform pharmaceuticals and illicit drugs is evaluated.

    An application of an unequal-weighted multi-objective decision making method in site selection of a waste sanitary landfill is discussed. The eight factors, which affected possible options, were: size and capacity of the landfill, permeability of the stratum, the average difference in elevation between the groundwater level and the bottom of the landfill pit, quality and source of clay, the quality grade of the landfill site, the effect of landfill engineering on nearby residents, distance to the water supply and the water source as well as the cost of construction and waste transport. These are determined, given the conditions of the geological environment, the need for environmental protection and landfill site construction and transportation related to the design and operation of a sanitary landfill. The weights of the eight factors were further investigated based on the difference in their relevance. Combined with practical experience from Xuzhou city (Jiangsu province, China), the objectives, effects and weights of grey decision-making were determined and the process and outcome of the landfill site selection are stated in detail. The decision-making results have been proven to be acceptable and correct. As we show, unequal-weighted multi-objective grey situation decision-mak- ing is characterized by easy calculations and good maneuverability when used in landfill site selection. The number of factors (objectives) affecting the outcome and the quantitative method of qualitative indices can be adjusted on the basis of concrete conditions in landfill site selection. Therefore, unequal-weighted multi-objective grey situation decision making is a feasible method in selecting landfill sites which offers a reference method for landfill site selection elsewhere. It is a useful, rational and scientific exploration in the choice of a landfill site.

    Full Text Available Context: Stroke has several consequences on survivors’ daily life even for those who experience short-lasting neurological symptoms with no functional disability. Depression and anxiety are common psychological disorders occurring after a stroke. They affect long-term outcomes and quality of life but they are difficult to diagnose because of the neurobiological consequences of brain lesions. Current research priority is given to the improvement of the detection and prevention of those post-stroke psychological disorders. Although previous studies have brought promising perspectives, their designs based on retrospective tools involve some limits regarding their ecological validity. Ecological Momentary Assessment (EMA is an alternative to conventional instruments that could be a key in research for understanding processes that underlined post-stroke depression and anxiety onset. We aim to evaluate the feasibility and validity of anxiety, depression and coping EMA for minor stroke patients.Methods: Patients hospitalized in an Intensive Neuro-vascular Care Unit between April 2016 and January 2017 for a minor stroke is involved in a study based on an EMA methodology. We use a smartphone application in order to assess anxiety and depression symptoms and coping strategies four times a day during 1 week at three different times after stroke (hospital discharge, 2 and 4 months. Participants’ self-reports and clinician-rates of anxiety, depression and coping are collected simultaneously using conventional and standard instruments. Feasibility of the EMA method will be assessed considering the participation and compliance rate. Validity will be the assessed by comparing EMA and conventional self-report and clinician-rated measures.Discussion: We expect this study to contribute to the development of EMA using smartphone in minor stroke population. EMA method offers promising research perspective in the assessment and understanding of post

    In order to reconstruct architectural changes during the centuries often we are forced to trust merely on the evidences of documentary and iconographical sources which could sometimes supply the description of the monument or of a specifically building phase. Such approach does not solve all the questions related to the interpretation of historical data (graphics, descriptions) useful for finding previous configurations of the building. The historical building structure and shape, as they appear at the present are often the final result of a stratification of different phases deeply connected with artistic and technological features of the age during which the building has been designed and realized. Stylistic features, building techniques and functional aspects change in time leaving often written traces in archive sources such as on the building masonry texture (sometimes hidden by plaster) or under the floor. In such situation the Non Destructive Testing investigations by means of infrared thermography and GPR could be useful to characterize masonry, to survey inhomogeneities in the masonry as well as to detect buried walls belongings to ancient building phases. This paper deals with the emblematic study case of San Francisco convent near Montella in Southern Italy. Its complex vicissitudes experienced in last centuries have been the reason of radical transformations of the church and its surrounding buildings. Historical research provided important information on structural interventions and planimetric transformations carried out between the 17th and 18th century. Such data have been correlated with the results obtained by infrared thermography surveys on plastered facades of the convent and GPR profiles carried out under the stone paved floor of the church and cloister, thus improving the knowledge of historical building phases of the monument. The integrated use of building analysis techniques based on NDT techniques together with historical and

    Ultraperformance liquid chromatography mass spectrometry (UPLC-MS), flow injection mass spectrometry (FIMS), and headspace gas chromatography (headspace-GC) combined with multivariate data analysis techniques were examined and compared in differentiating organically grown oregano from that grown conventionally. It is the first time that headspace-GC fingerprinting technology is reported in differentiating organically and conventionally grown spice samples. The results also indicated that UPLC-MS, FIMS, and headspace-GC-FID fingerprints with OPLS-DA were able to effectively distinguish oreganos under different growing conditions, whereas with PCA, only FIMS fingerprint could differentiate the organically and conventionally grown oregano samples. UPLC fingerprinting provided detailed information about the chemical composition of oregano with a longer analysis time, whereas FIMS finished a sample analysis within 1 min. On the other hand, headspace GC-FID fingerprinting required no sample pretreatment, suggesting its potential as a high-throughput method in distinguishing organically and conventionally grown oregano samples. In addition, chemical components in oregano were identified by their molecular weight using QTOF-MS and headspace-GC-MS.

    This paper presents data of a study undertaken to know the sanitary features of water supply (deep pools) for human consumption in the city of Campeche, Mexico. Levels of intestinal bacteria (total and fecal coliforms) were monitored, as well as heterotrophic plate counts and the surroundings of each deep pool were inspected. Each water supply was monitored three times from January to July, 1993 and presented unacceptable levels of heterotrophic plate counts and coliforms which is a strong evidence of fecal contamination of animal or human origin. These findings are a clear indication of unacceptable contamination of water supply for human consumption which requires an improvement and systematic inspection in order to provide good quality water to the population of Campeche.

    Sanitary and nutritional control of meals distributed by school catering services is one of the institutional duties of the Food Hygiene and Nutrition Services (Servizi Igiene Alimenti e Nutrizione - SIAN) of the Local Health Units. In order to carry out this activity properly it is necessary to ask oneself beforehand what the main outcome of control activities should be. The answer to this question can only be that "proper nutrition is essential for healthy growth". Starting from this assumption, control activities performed along the entire chain of the scholastic catering service, starting from the final dish served at school up to the primary producer, were reviewed. The review was carried out by a team of multiprofessionals which included a physician, a prevention technician, a dietician, a biologist, an agronomist and a veterinarian. Preliminary results are extremely positive and show that the multidisciplinary integration of roles entrusted to the coordinators of SIAN is crucial to obtaining the best results.

    A jet inncr-loop bioreactor (JIBR) was used to treat synthetic sanitary sewage with low, medium and high COD load. The experimental resuhs show that it could meet discharge standard at 20-30 min of HRT (hydraulic retention time) for low COD concentration and 60-120 min of HRT for medium and high COD concentration. The maximal COD volume loading and COD sludye loading of 27kg·m-3·d-1 and 5 kg/d per kg MLSS were achieved respectively, that were 10-20 times higher than those of traditional wastewater treatment processes. The BOD5 removal efficiency was more than 90 % and NH1-N more than 85 %. The study on the activity showed that the oxygen consumption rate of the activated times higher than that of the SBR(Sequencing Batch Reactor)and thc dominant bacteria in jet inner-loop bioreactor was Pseudomonas species.

    Full Text Available Abstract Background The coronary artery calcium (CAC score is an independent predictor of coronary heart disease. We sought to combine information from the CAC score with information from conventional cardiac risk factors to produce post-test risk estimates, and to determine whether the score may add clinically useful information. Methods We measured the independent cross-sectional associations between conventional cardiac risk factors and the CAC score among asymptomatic persons referred for non-contrast electron beam computed tomography. Using the resulting multivariable models and published CAC score-specific relative risk estimates, we estimated post-test coronary heart disease risk in a number of different scenarios. Results Among 9341 asymptomatic study participants (age 35–88 years, 40% female, we found that conventional coronary heart disease risk factors including age, male sex, self-reported hypertension, diabetes and high cholesterol were independent predictors of the CAC score, and we used the resulting multivariable models for predicting post-test risk in a variety of scenarios. Our models predicted, for example, that a 60-year-old non-smoking non-diabetic women with hypertension and high cholesterol would have a 47% chance of having a CAC score of zero, reducing her 10-year risk estimate from 15% (per Framingham to 6–9%; if her score were over 100, however (a 17% chance, her risk estimate would be markedly higher (25–51% in 10 years. In low risk scenarios, the CAC score is very likely to be zero or low, and unlikely to change management. Conclusion Combining information from the CAC score with information from conventional risk factors can change assessment of coronary heart disease risk to an extent that may be clinically important, especially when the pre-test 10-year risk estimate is intermediate. The attached spreadsheet makes these calculations easy.

    Posture, vision, and instrumentation limitations are the main predicaments of conventional laparoscopy. To combine the ETHOS surgical chair, the three-dimensional laparoscope, and the Radius Surgical System manipulators, and compare the system with conventional laparoscopy and da Vinci in terms of task completion times and discomfort. Fifteen trainees performed the three main laparoscopic suturing tasks of the Heilbronn training program (IV: simulation of dorsal venous complex suturing; V: circular suturing of tubular structure; and VI: urethrovesical anastomosis) in a pelvi trainer. The tasks were performed conventionally, utilizing the three devices, and robotically. Task completion times were recorded and the surgeon discomfort was evaluated using questionnaires. Task completion times were compared using nonparametric Wilcoxon signed rank test and ergonomic scores were compared using Pearson chi-square test. The use of the full laparoscopic set (ETHOS chair, three-dimensional laparoscopic camera, Radius Surgical System needle holders), resulted in a significant improvement of the completion time of the three tested tasks compared with conventional laparoscopy (psystem nullified heavy discomfort for Tasks IV and V and minimized it (6.7%) for the most demanding Task VI. Especially for Task VI, all trainees gained benefit, by using the system, in terms of task completion times and discomfort. The limited trainee robotic experience and the questionnaire subjectivity could be a potential limitation. The ergonomic laparoscopic system offers significantly improved task completion times and ergonomy than conventional laparoscopy. Furthermore, it demonstrates comparable results to robotic surgery. The study was conducted in a pelvi trainer and no patients were recruited. Copyright © 2016 European Association of Urology. Published by Elsevier B.V. All rights reserved.

    Decontaminating dental chair unit (DCU) suction systems in a convenient, safe and effective manner is problematic. This study aimed to identify and quantify the extent of the problems using 25 DCUs, methodically eliminate these problems and develop an efficient approach for reliable, effective, automated disinfection. DCU suction system residual contamination by environmental and human-derived bacteria was evaluated by microbiological culture following standard aspiration disinfection with a quaternary ammonium disinfectant or alternatively, a novel flooding approach to disinfection. Disinfection of multicomponent suction handpieces, assembled and disassembled, was also studied. A prototype manual and a novel automated Suction Tube Cleaning System (STCS) were developed and tested, as were novel single component suction handpieces. Standard aspiration disinfection consistently failed to decontaminate DCU suction systems effectively. Semi-confluent bacterial growth (101-500 colony forming units (CFU) per culture plate) was recovered from up to 60% of suction filter housings and from up to 19% of high and 37% of low volume suction hoses. Manual and automated flood disinfection of DCU suction systems reduced this dramatically (ranges for filter cage and high and low volume hoses of 0-22, 0-16 and 0-14CFU/plate, respectively) (Psuction handpieces could not be adequately disinfected without prior removal and disassembly. Novel single component handpieces, allowed their effective disinfection in situ using the STCS, which virtually eliminated contamination from the entire suction system. Flood disinfection of DCU suction systems and single component handpieces radically improves disinfection efficacy and considerably reduces potential cross-infection and cross-contamination risks. DCU suction systems become heavily contaminated during use. Conventional disinfection does not adequately control this. Furthermore, multicomponent suction handpieces cannot be adequately

    The Department of Physiology of Pramukhswami Medical College at Anand, Gujarat, India, started using problem-based learning in a modified way along with didactic lectures to improve students' understanding and motivate them toward self-directed study. After the didactic lectures were taken for a particular system, clearly defined short clinical problems related to that system were given to the students in the tutorial classes. Each tutor was assigned three to four groups of five to six students each. Problems were accompanied with relevant questions so as to streamline the thought processes of the first-year undergraduates. The tutor then facilitated the study process, and the students discussed among themselves to derive their solutions. At the end of the sessions, feedback was taken from the students through a planned questionnaire on a three-point scale. Of a total of 278 students over a span of 3 yr from 1999 to 2002, 74.4% of students favored a judicious mixture of didactic lectures and case-oriented problem solving in tutorial classes to be an efficient modality in understanding a system under study, and 84% of students stated the mixture of didactic lectures and case-oriented problem solving to be beneficial in relating a clinical condition to the basic mechanism; 82% of students believed that this module helped with better interactions among their batch mates, and 77.2% of students hoped to perform better in the university examination due to this new teaching/learning modality. They also expressed that this gave them ample motivation to do self-directed learning. It may therefore be concluded from the results of the present study that it is possible to have a problem-based learning module in the form of case-oriented problem-solving tutorials coexistent with the traditional didactic lecture module in the first year of medical education under a conventional curriculum.

    Objective To outline and discuss the main challenges for sanitary regulation contained in the federal-level Brazilian health policy. Methods For the present qualitative study, based on the analysis of public policies, information was collected from documents and interviews. Document analysis provided a historical overview of the insertion of sanitary regulation into the Brazilian health policy between 1999 and 2009 (first decade of existence of the national health surveillance agency, Anvisa). In addition, 13 interviews were carried out with actors selected for their historical, technical, or academic role in the field. Content analysis was used to define themes emerging from the materials analyzed with a focus on the "content" category, which refers to strategic and operational guidelines of policy programs, projects, initiatives, and normative framework. Results Content analysis revealed five themes that reflect the challenges to sanitary regulation in Brazil: 1) objects under regulation treated as isolated cases; 2) a Brazilian-specific model of sanitary regulation that is different from other international models; 3) ignorance regarding the role of sanitary surveillance in health care; 4) absence of an information system; and 5) absence of performance indicators and assessment tools. Conclusions Sanitary surveillance must have a mission that is disentangled from inspection tasks to become an effective instrument of health protection. For that, an information system that brings the National Sanitary Surveillance System together toward major objectives is essential. The adoption of tools for assessment of action is also required, with the establishment of adequate indicators.

    Ethiopia is one of the poorest countries of the word, with over 85 % of total population dependent from agriculture. Massive deforestation in the past and missing soil and water conservation (SWC) measures cause severe soil erosion problems in the northern highlands of Ethiopia. Different SWC methods are supposed to prevent ongoing land degradation, which is triggered by rainfall driven soil erosion in the Ethiopian agricultural lands. Common technologies for soil and water conservation are stone bunds, which reduce surface runoff and sediment loss. In June 2015 two field experiments were set up in the Gumara-Maksegnit watershed in Northern Ethiopia. The objective of this study was to evaluate the impact of graded stone bunds on surface runoff and sediment yield by using conventional and tracing approaches. Three consecutive runoff plots of 20 x 4 m length and width, respectively were established along the maximum slope direction. Each one was separated to the downstream one by a stone bund. The experimental setup allowed the measurement of surface runoff along each stone bund and the measurement of overflow over the lowest stone bund. To assess the pathway and the spatial distribution of the sediments a different tracer (Magnetite, Hematite and Goethite) was applied in a 40 cm wide strip at the top of each one of the plots. The second tracer experiment was conducted on the same hillslope. It consisted of a 20 m long hillslope without borders in which a 4 m long and 40 cm wide Magnetite strip was placed at the top. At the end of August 2015 soil samples of 0-2 cm depth were taken in a 1.5 x 1.5 m grid within the area of the hillslope. Soil samples parallel to the stone bund (above and underneath) were taken along 16 m to assess the soil movement/deposition. Tracer concentrations of soil and sediment samples in both trials were analysed. Runoff and sediment were collected in weekly intervals from July to September. Runoff and erosion data, as well as the evaluation

    Although Dickens is still known as having been a highly visible supporter of England's well-known nineteenth-century sanitary movement, he became, in fact, deeply troubled by many of this movement's fundamental tenets, as evidenced by journal narratives on fever that he edited and wrote in the mid-nineteenth century. Rather than water and sewer engineering works and a sanitary regime policed by government agencies as envisaged by Edwin Chadwick and other sanitary reformers, Dickens's view by 1855 was that only a massive erasure of the existing social and political systems and their replacement by an utterly new infrastructure would suffice.

    Nutritional depletion in chronic obstructive pulmonary disease (COPD) adversely affects health status and mortality. We aimed to evaluate the effects of nutritional supplementation (NS) with pulmonary rehabilitation (PR) on body composition, mid-thigh cross-sectional area (CSA), dyspnoea, exercise capacity, health-related quality of life, anxiety and depression in advanced COPD patients. Forty-six patients were randomized to PR and nutritional support (PRNS), PR or the control group. Dyspnoea was measured with Medical Research Council and BORG scales. Exercise capacity was measured through 6-min walk test and shuttle tests; health-related quality of life was assessed with St. George's Respiratory Questionnaire. Psychological status was measured with Hospital Anxiety and Depression Scale. Body weight and body mass indexes (BMI) were also evaluated. Fat-free mass was measured through bioelectrical impedance analyser. The CSA of quadriceps was calculated in mid-level of the thigh with magnetic resonance imaging. Dyspnoea and total scores of St. George's Respiratory Questionnaire improved in both groups (P < 0.05). Six-minute walk test and incremental shuttle walk test distances in PRNS and PR patients increased significantly as (62.6 ± 42.4 m, 43.3 ± 59.2 m, both P = 0.001; and 63.3 ± 70.1 m and 69.3 ± 69.7 m, both P = 0.001). Although anxiety improved in both groups (P < 0.05), there was no change in depression. Body weight, BMI and fat-free mass index (FFMI) (1.1 ± 0.9 kg, 0.2 ± 1.4 kg/m(2) and 0.6 ± 0.5 kg/m(2), P < 0.05) in PRNS, whereas body weight and FFMI (0.6 ± 0.7 kg, 0.1 ± 0.6 kg/m(2) P < 0.05) increased in PR after the intervention. There was a significant increase in mid-thigh CSA (2.5 ± 4.1 cm(2)) only in PRNS (P = 0.04). The combination of NS with PR resulted in improvements particularly in lean body mass and mid-thigh CSA. This study suggests combining NS with PR in reversing

    In accordance with 10 CFR 20, the US Nuclear Regulatory Commission (NRC) regulates licensees` discharges of small quantities of radioactive materials into sanitary sewer systems. This generic study was initiated to examine the potential radiological hazard to the public resulting from exposure to radionuclides in sewage sludge during its treatment and disposal. Eleven scenarios were developed to characterize potential exposures to radioactive materials during sewer system operations and sewage sludge treatment and disposal activities and during the extended time frame following sewage sludge disposal. Two sets of deterministic dose calculations were performed; one to evaluate potential doses based on the radionuclides and quantities associated with documented case histories of sewer system contamination and a second, somewhat more conservative set, based on theoretical discharges at the maximum allowable levels for a more comprehensive list of 63 radionuclides. The results of the stochastic uncertainty and sensitivity analysis were also used to develop a collective dose estimate. The collective doses for the various radionuclides and scenarios range from 0.4 person-rem for {sup 137}Cs in Scenario No. 5 (sludge incinerator effluent) to 420 person-rem for {sup 137}Cs in Scenario No. 3 (sewage treatment plant liquid effluent). None of the 22 scenario/radionuclide combinations considered have collective doses greater than 1000 person-rem/yr. However, the total collective dose from these 22 combinations was found to be about 2100 person-rem.

    Purpose. To evaluate surgical efficacy of in situ refixation technique for dislocated posterior chamber intraocular lens (PCIOL). Methods. This was a single-center retrospective case series. 34 patients (34 eyes) who underwent sclera fixation for dislocated IOLs combined with vitrectomy were studied. Of 34 eyes, 17 eyes underwent IOL exchange and the other 17 eyes underwent in situ refixation. Results. Mean follow-up period was 6 months. Mean logMAR best corrected visual acuity (BCVA) was not significantly different between the groups 6 months after surgery (0.10 ± 0.03 in the IOL exchange group and 0.10 ± 0.05 in the refixation group; p = 0.065). Surgically induced astigmatism (SIA) was significantly lower in the refixation group (0.79 ± 0.41) than in the IOL exchange group (1.29 ± 0.46) (p = 0.004) at 3 months, which persisted to 6 months (1.13 ± 0.18 in the IOL exchange group and 0.74 ± 0.11 in the refixation group; p = 0.006). Postoperative complications occurred in 3 eyes in the IOL exchange group (17.6%) and 2 eyes in the refixation group (11.8%). However, all of the patients were well managed without additional surgery. Conclusion. The in situ refixation technique should be preferentially considered if surgery is indicated since it seemed to produce a sustained less SIA compared to IOL exchange. PMID:27119019

    The infectious Salmon Anemia virus (ISAv) is a pathogen that mainly affects the Atlantic Salmon (Salmo salar). It was detected in Norway in 1984 and in June 2007 appeared in Chile, producing a drop of more than 30% in the country's production level. It is expected that with certain regularity, outbreaks will continue to appear in Chile without the need of reintroducing the virus from foreign countries. We present a numerical study of the influence of winds and tides in the dispersion of lagrangian particles to simulate the transport of ISAv in the Aysen region, in southern Chile. This study combines the use of numerical models of the ocean and atmosphere, lagrangian tracking and biological aspects of ISAv infections. As in previous results, a wider dispersion of ISAv was observed during spring tides. Temporal changes in wind significantly modified the transport of viral particles from an infected center. Under similar forcing conditions, the areas of risk associated to culture sites separated by a few kilometers could be very different. Our main results remark the importance of the use of a detailed knowledge of hydrographic and atmospheric circulation in the definition of boundaries for sanitary management areas. We suggest that a methodology similar to the one presented in this study should be considered to define sanitary strategies to minimize the occurrence of native outbreaks of ISAv.

    This paper focuses on the application of a multi-criteria analysis methodology - the analytical hierarchy process - for the locating of a sanitary landfill on the small island of Mauritius. Four candidate sites were assessed using three main criteria (environmental, technical and socio-economic) and twenty-one sub-criteria. Scores were assigned to each criterion and sub-criterion by stakeholders in the solid waste sector, based on the impact assessment of each site so as to obtain their relative importance. The analytical hierarchy process was then applied, which involved the combination of the weights obtained at the different stages of pair-wise comparisons. The candidate sites were finally ranked to obtain the optimum site. Because of political factors, the second best ranked site was chosen by the authorities for the location of a new landfill on the island. This technique provides a realistic approach for use by small island developing states such as Mauritius for choosing and justifying to all stakeholders the best location for a sanitary landfill site or any other waste management site.

    Adequate waste management is vital for the success of social life, because waste accumulation increases sanitary risks in dense societies. We explored why different leaf-cutting ants (LCA) species locate their waste in internal nest chambers or external piles, including ecological context and accounting for phylogenetic relations. We propose that waste location depends on whether the environmental conditions enhance or reduce the risk of infection. We obtained the geographical range, habitat and refuse location of LCA from published literature, and experimentally determined whether pathogens on ant waste survived to the high soil temperatures typical of xeric habitats. The habitat of the LCA determined waste location after phylogenetic correction: species with external waste piles mainly occur in xeric environments, whereas those with internal waste chambers mainly inhabit more humid habitats. The ancestral reconstruction suggests that dumping waste externally is less derived than digging waste nest chambers. Empirical results showed that high soil surface temperatures reduce pathogen prevalence from LCA waste. We proposed that LCA living in environments unfavourable for pathogens (i.e. xeric habitats) avoid digging costs by dumping the refuse above ground. Conversely, in environments suitable for pathogens, LCA species prevent the spread of diseases by storing waste underground, presumably, a behaviour that contributed to the colonization of humid habitats. These results highlight the adaptation of organisms to the hygienic challenges of social living, and illustrate how sanitary behaviours can result from a combination of evolutionary history and current environmental conditions.

    Full Text Available This investigation has three primary aims: 1 to study the traditional knowledge of Benjarong in Samut Sakhon Province; 2 to study designs and the production process of Benjarong sanitary ware in Samut Sakhon Province; 3 to develop Benjarong sanitary ware for commerce in Samut Sakhon Province. The research area for this investigation was purposively selected as Samut Sakhon Province. Data was gathered by document study, survey, participant and non-participant observation, structured and non-structured interview, focus group discussion and workshop. Results show that Benjarong sanitary products have been inherited from generation to generation in Samut Sakhon Province and continue to provide local jobs. Benjarong sanitary ware production uses a high budget because of the high price of colour inks, gold and electricity, so there are problems securing adequate funding. There are also problems with the management process and a lack of expert craftsmen to write and design modern patterns in harmony with contemporary art and Thai social identity. Moreover, many Thai people do not realize the value of cultural heritage and Benjarong inheritance is at risk. Benjarong sanitary ware can reflect local knowledge and traditional handicrafts. The researchers propose patterns for three types of Benjarong sanitary ware: washbasins, wall tiles and soap ledges. Development of these products will increase functionality and aesthetics, whilst maintaining Thai heritage.

    This study investigated the physiological and psychological effects of sanitary napkins (SN) on women in hemorrhage treatment during the menstrual phase. Mesh and non-woven napkins were employed, and the effects were studied during the follicular and menstrual phases; mesh SN presented a higher textural surface-roughness. In both phases, the increases in systolic and diastolic blood pressure were significantly dependent on the application intervals. The low-frequency component of systolic blood pressure variability significantly increased, while the salivary secretion rate decreased with the use of mesh SN during the follicular phase compared with non-woven SN. In addition, the heart rate during the menstrual phase significantly increased in subjects after the replacement of mesh SN compared with non-woven SN. In cases of wearing the unpleasant mesh SN, electroencephalography (EEG) manifested bilateral enhancements in beta and alpha2 waves in the frontal areas increased arousal level during both phases. From the above findings, napkin use increased physiological loading and wearing napkins with higher textural surface-roughness tended to increase activities of the autonomic nervous system and brain arousal level.

    Full Text Available The objectives were to identify maize germplasm for the organic productions system and to compare the genetic effects of the grain yield of maize cultivars in organic and conventional production systems. Diallel crosses were made between six maize cultivars and the hybrid combinations were evaluated in conventional and organic production systems. The hybrid combinations produced different grain yields in the two production systems. The interaction between general combining ability and production systems was significant for grain yield, ear height and number of ears. This indicates that the additive genetic effects differ in organic and conventional production systems. The specific combining abilities (SCA were significant for grain yield and plant height, indicating a significant difference between the non-additive effects. However, the SCA x production systems interactions were not significant for those traits. It was concluded that for the development of maize cultivars for the organic production system, selection must be made in the specific environment for the expression of favorable alleles that confer advantages for adapting to this system; the general combining ability of genitors is different for the two production systems, but the specific combining ability isn't different in organic and conventional systems.Os objetivos foram identificar germoplasma de milho para o sistema de produção orgânica e comparar os efeitos genéticos da produtividade de grãos de cultivares de milho em sistemas de produção orgânico e convencional.

In its surroundings live circa 16 million inhabitants, out of which 6 million live in Rio de Janeiro city, one of the largest cities of the country, and the host of the 2016 Olympic Games. Anthropogenic interference in Guanabara Bay area started early in the XVI century, but environmental impacts escalated from 1930, when this region underwent an industrialization process. Herein we present an overview of the current environmental and sanitary conditions of Guanabara Bay, a consequence of all these decades of impacts. We will focus on microbial communities, how they may affect higher trophic levels of the aquatic community and also human health. The anthropogenic impacts in the bay are flagged by heavy eutrophication and by the emergence of pathogenic microorganisms that are either carried by domestic and/or hospital waste (e.g., virus, KPC-producing bacteria, and fecal coliforms), or that proliferate in such conditions (e.g., vibrios). Antibiotic resistance genes are commonly found in metagenomes of Guanabara Bay planktonic microorganisms. Furthermore, eutrophication results in recurrent algal blooms, with signs of a shift toward flagellated, mixotrophic groups, including several potentially harmful species. A recent large-scale fish kill episode, and a long trend decrease in fish stocks also reflects the bay’s degraded water quality. Although pollution of Guanabara Bay is not a recent problem, the hosting of the 2016 Olympic Games propelled the government to launch a series of plans to restore the bay’s water quality. If all plans are fully implemented, the restoration of Guanabara Bay and its shores may be one of the best legacies of the Olympic Games in Rio de Janeiro. PMID:26635734

    Obiettivi: valutazione della prevalenza di fumatori negli studenti di medicina e di infermieristica al fine di migliorarne le competenze e i comportamenti in tema di tabagismo, in vista anche del loro futuro ruolo nelle Aziende Sanitarie1.

    Materiali e metodi: nell’ambito della Facoltà di Medicina dell’Università di Bologna è stato condotto uno studio sugli aspetti motivazionali e comportamentali delle abitudini al fumo nei giovani iscritti al primo anno di Medicina e di Infermieristica negli AA 1999-2000 e 2002-2003. L’indagine è stata svolta somministrando questionari anonimi agli studenti in aula. Si è ottenuta così una percentuale di rispondenti pari all’ 87 e al 90% della popolazione studentesca iscritta. Risultati: la prevalenza di fumatori cronici o occasionali è andata incrementandosi negli ultimi due anni del 7% tra gli studenti di infermieristica e dell’8,8% tra quelli di medicina, sino a raggiungere rispettivamente il 42,4% e il 25,7%. Nel 2002 il 13,5% dei fumatori ha dichiarato di contemplare la possibilità di smettere entro la fine del corso di studi. Nonostante la giovane età, il 10% di loro erano recidivi da tentativi di disassuefazione falliti.

    Conclusioni: evidente il trend di aumento dell’abitudine al fumo nelle categorie considerate e la difficoltà, a volte notevole, di evitare ricadute nel tabagismo in assenza di adeguato sostegno. Da questi dati è emersa la necessità di impegnarsi per garantire agli studenti sia una più specifica preparazione (si è previsto nel curriculum studi un modulo elective sul tabagismo che una possibilità di disassuefazione precoce, grazie a un canale preferenziale presso il centro per la Disassuefazione dal Fumo di Tabacco dell’ Azienda S.

    The aims of our study were to determine whether shear wave elastography (SWE) can improve the conventional B-mode differentiation of thyroid lesions, determine the most accurate SWE parameter for differentiation and assess the influence of microcalcifications and chronic autoimmune thyroiditis on SWE values. We examined 119 patients with 169 thyroid nodules who prospectively underwent B-mode ultrasound and SWE using the same ultrasound machine. The parameters assessed using SWE were: mean elasticity within the entire lesion (SWE-whole) and mean (SWE-mean) and maximum (SWE-max) elasticity for a 2-mm-diameter region of interest in the stiffest portion of the lesion, excluding microcalcifications. The discriminant powers of a generalized estimating equation model including B-mode parameters only and a generalized estimation equation model including both B-mode and SWE parameters were assessed and compared using the area under the receiver operating characteristic curve, in association with pathologic verification. In total, 50 and 119 malignant and benign lesions were detected. In generalized estimated equation regression, the B-mode parameters associated with higher odds ratios (ORs) for malignant lesions were microcalcifications (OR = 4.3), hypo-echogenicity (OR = 3.13) and irregular margins (OR = 10.82). SWE-max was the only SWE independent parameter in differentiating between malignant and benign tumors (OR = 2.95). The area under the curve for the B-mode model was 0.85, whereas that for the model combining B-mode and SWE parameters was 0.87. There was no significant difference in mean SWE values between patients with and without chronic autoimmune thyroiditis. The results of the present study suggest that SWE is a valuable tool for the characterization of thyroid nodules, with SWE-max being a significant parameter in differentiating benign and malignant lesions, independent of conventional B-mode parameters.

    At the time of the Second Republic of Poland, Warsaw, the capital of the rebirth country, was a neglected town as regards sanitary conditions. The genesis of this situation dates back to the period of the national bondage by the Russian partitioner, and since 1915 by the German invader who did not care about the problems associated with public health. The sanitary and hygienic conditions worsened significantly in 1916, after incorporating into Warsaw large out-of-town regions whose housing was of the rural character with numerous wooden cottages, field roads, without any sanitary sewage system. Poor municipal sanitary-maintenance conditions and infectious diseases spreading in Warsaw made the Town Authorities implement preventive action and entrust sanitary surveillances with this difficult task. These surveillances were set up at the time of the First World War, and after 1920 were changed into sanitary offices. Their duties included control of acute infectious diseases, sanitary inspection of living quarters, sites of production and selling of food articles, plants, service outlets, shops of a different character, as well as surveillance of food purchased by the inhabitants. In each sanitary office a doctor was employed who supervised the work of one, two or three sanitary inspectors.

    At the time of the Second Republic of Poland, in March 1922, the city of Vilnius together with the Vilnius Region was incorporated into Poland. Sanitary and health negligence was one of the main problems of the city. The genesis of that situation dates back to the 120-year national bondage, when the city was under the Russian rule. Since 1915 it was occupied by the German invader, and from January to April 1919 it belonged to Soviet Russia. The legacy left by this epoch concerned bad housing conditions, problems with removal of impurities, scarcity of fresh water supply, uneven and dirt roads, which along with other bionegative factors resulted in dissemination of contagious diseases and occurrence of other health risks. In Vilnius of the interwar period, similarly to other big cities in Poland, sanitary surveillances played a significant role in controlling acute contagious diseases, inspecting sanitary conditions of living quarters, service outlets, industrial plants, sites of production and selling food articles, as well as surveillance of food. Municipal doctors supervised the work of sanitary inspectors in each sanitary office.

    The recovery of the biogas generated from sanitary landfills, associated to its energetic use has been widely discussed. Thus, this paper aims to estimate the potential production of electric energy from sanitary landfill Santo Andre-SP. The biogas production was estimated using the rate of deposition of solid wastes in the landfill, using some mathematical models with parameters suggested by two models: LanGEM-USEPA (conventional landfill) and Word Bank. These results indicate that the potential of biogas production will be approximately 11 x 10{sup 6} Kg of methane/year in 2017 and production of electric energy in that year will be approximately 32,000 MWh, considering an of 75% over collection of biogas.

    Bollgard(®) III was developed by combining cotton events COT102 and MON 15985 through conventional breeding to improve efficacy against lepidopteran feeding damage. COT102 produces the Vip3Aa19 protein and MON 15985 produces the Cry1Ac and Cry2Ab2 proteins. COT102 × MON 15985 has also been bred with Roundup Ready Flex(®) cotton (MON 88913) that confers glyphosate tolerance. This study evaluated the activity of COT102 and MON 15985 and the combined activity of COT102 and MON 15985 against the cotton bollworm (CBW, Helicoverpa zea). COT102, MON 15985, COT102 × MON 15985 and COT102 × MON 15985 × MON 88913 have comparable Vip3Aa19 and/or Cry1Ac, Cry2Ab2 protein expression levels as determined by enzyme-linked immunosorbent assay. CBW demonstrated concentration-dependent growth inhibition after 7-days of feeding on lyophilized leaf tissue derived from COT102, MON 15985, COT102 × MON 15985 and COT102 × MON 15985 × MON 88913 incorporated into an artificial diet. Observed EC50 values for COT102 × MON 15985 and COT102 × MON 15985 × MON 88913 were comparable (≤4% deviation) with the predicted EC50 value under the assumption of additivity using the combined activity of COT102 and MON 15985. No interaction in biological activity between COT102 and MON 15985 is consistent with results from competition and ligand blotting assays that demonstrated that Vip3Aa does not inhibit the binding of either Cry1Ac or Cry2Ab2 and vice versa. The results from this study demonstrate that the activity of COT102 × MON 15985 against CBW is consistent with predictions of additivity.

    At the beginning of the First World War the most typical diseases in the Russian Army were typhoid, typhus, diphtheria, cholera, smallpox and other infectious diseases. At the beginning of the First World War the level of infectious morbidity was significantly low, but further increased and pandemic risk arose. Servicemen were mostly ill with typhus, relapsing fever, flux, cholera, smallpox and typhoid. The highest mortality rate was registered in patients with cholera, typhus and typhoid. According the prewar deployment program of the Russian Army anti-epidemiologic facilities were established. By the end of war were established 110 sanitary-and-hygienic and 90 disinfection units. However, organization of anti-epidemiologic security was unsatisfactory. Due to lack of specialists and equipment anti-epidemiologic facilities of units were under strength. Commanders of sanitary units and sanitary service had not enough resources for operational service in the Forces and facilities of rear area.

    This research paper presents a comparative study of the performance of conventional, ultrasound-assisted (UA), and temperature-controlled (TC) ionic liquid (IL) dispersive liquid-phase microextraction (IL-DLLME). Various parameters that affect extraction efficiency, such as type and volume of extraction and disperser solvent, centrifugation time, salt addition, effect of temperature on TC-IL-DLLME, and effect of sonication time on UA-IL-DLLME, were evaluated. UA-IL-DLLME was found to provide the best extraction efficiency. Under optimized conditions, great enrichment factors (506-515) and good recoveries (101.2-103.0%) were obtained by analyte extraction in real samples. The limit of detections (LODs) ranged from 0.21 to 0.38 μg L(-1). Good linearity was obtained in the range of 0.5-200 μg L(-1) for ethofenprox and tetramethrin, and 1-200 μg L(-1) for meperfluthrin and alpha-cypermethrin. Based on optimized conditions, the UA-IL-DLLME method was applied and combined with high-performance liquid chromatography with diode array detection (HPLC-DAD) to determine the presence of ethofenprox, tetramethrin, meperfluthrin, and alpha-cypermethrin in honey samples.

    microenvironment. It has been reported that metronomic chemotherapy enjoys obvious advantages in improving tumor microenvironment. The purpose of this study was to compare the antitumor effects in nude mice with human breast cancer with different cyclophosphamide chemotherapy regimens and to observe two balances: between pro-angiogenesis and anti-angiogenesis and between tumor cell proliferation and apoptosis. Methods: Breast ortho-topic transplantation tumor model was established. Twenty nude mice bearing carcinoma were divided into 4 groups randomly: metronomic chemotherapy group (LDM), conventional chemotherapy group (MTD), combination group (LDM+MTD) and control group. The general condition of mice was observed and the mice were weighed every other day, at the same time the volume of subcutaneous tumor was measured. WBC was counted every week. In the end, tumors were taken off and weighed to calculate inhibitory rates of each group. Immunohistochemistry was used to detect the tumor microvessel density (MVD), and the expressions of VEGF, TSP-1 and PCNA. TUNEL was used to detectthe apoptosis of the tumor cells. Results: All nude mice were in good condition throughout the trial period without significant side effects. Three chemotherapy regimens could inhibit the growth of xenografts in different degrees, whose inhibitory rates were 32.95%, 41.75% and 69.15%, respectively. LDM and MTD had similar tumor growth curve, while the xenografts in combination group appeared to grow significantly slower than the other groups. In the combination group and LDM group, xenografts expressed lower level VEGF and MVD and higher level TSP-1 than those in the other groups (P0.05). There was lower expression of PCNA in the combination group and MTD group than those in the LDM and control groups (P0.05). The apoptosis index (AI) in three chemotherapy groups had statically significant difference with control group (P<0.05). Furthermore, the AI in the combination group was the highest. Conclusion

    Full Text Available Qualitative study whose objective is to know battered women perception regarding sanitary professional’s attention on gender violence in Madrid Community. The results were validated by a triangulation process. Women identified sanitary assistance with those given when there exist physical injuries. However, if we keep questioning about it, they do express to look for something else from the professionals who attended them, although they are not able to say it before them.Somatizations that ill-treatment produces are treated by sanitary professionals without attending to the cause that caused them, and, when it is identified ill-treatment as the cause, rarely sanitary professionals send them to psychologies or psychiatrics. However, this is not identified as a bad practice, because women establish a very defined and rigid function for each professional, where, as they understand, Primary Care doctor will not be required to worry about psychic health and wellbeing of people who attend to their offices.We think, therefore, that it would be recommended that Madrid Community should create a specific health program to attend these women in order to guarantee, this way, a proper attention to people who may be in this situation as well as a minimum quality on the attention they received.

    Information about the quality of rural drinking water sources can be used to manage their safety and mitigate risks to health. Sanitary surveys, which are observational checklists to assess hazards present at water sources, are simpler to conduct than microbial tests. We assessed whether sanitary survey results were associated with measured indicator bacteria levels in rural drinking water sources in Kisii Central, Kenya. Overall, thermotolerant coliform (TTC) levels were high: all of the samples from the 20 tested dug wells, almost all (95%) of the samples from the 25 tested springs, and 61% of the samples from the 16 tested rainwater harvesting systems were contaminated with TTC. There were no significant associations between TTC levels and overall sanitary survey scores or their individual components. Contamination by TTC was associated with source type (dug wells and springs were more contaminated than rainwater systems). While sanitary surveys cannot be substituted for microbial water quality results in this context, they could be used to identify potential hazards and contribute to a comprehensive risk management approach.

    Sanitary conditions are essential for the production of meals and control of the presence of pathogensis important to guarantee the health of customers. The aim of this study was to evaluate the sanitary quality of food services by checking the presence of thermotolerant coliforms, Staphylococcus sp. and evaluate the toxigenic potential from the latter. The analysis was performed on water, surfaces, equipment, ready-to-eat foods, hands and nasal cavity of handlers in seven food services. The water used in food services proved to be suitable for the production of meals. Most food, equipment and surfaces showed poor sanitary conditions due to the presence of thermotolerant coliforms (60.6%). Twenty-six Staphylococcus species were identified from the 121 Staphylococcus isolates tested. Staphylococci coagulase-negative species were predominant in the foods, equipment and surfaces. In food handlers and foods, the predominant species was Staphylococcus epidermidis. Twelve different genotypes were found after PCR for the classical enterotoxin genes. The seb gene (19.8%) was the most prevalent among all Staphylococcus sp. Both coagulase-positive and coagulase-negative Staphylococci showed some of the genes of the enterotoxins tested. We conclude that there are hygienic and sanitary deficiencies in the food services analyzed. Although coagulase-positive Staphylococci have not been present in foods there is a wide dispersion of enterotoxigenic coagulase-negative Staphylococci in the environment and in the foods analyzed, indicating a risk to consumer health.

    There is growing evidence that requirements for particular AA increase when pigs are kept under low sanitary conditions. The extent to which reduction in growth performance is related to these increased requirements is unclear. To evaluate this relationship, an experiment (2 × 2 × 2 factorial arrangement) was performed with 612 male pigs (9 per pen) kept under low sanitary conditions (LSC) or high sanitary conditions (HSC) and offered ad libitum access to either a normal CP concentration diet (NP; 17, 15, and 15% CP for the starter, grower, and finisher phase, respectively) or a low CP concentration diet (LP; 20% CP reduced relative to NP for each phase), each of which containing a basal AA profile (AA-B) or a supplemented AA profile (AA-S). The supplemented diet type contained 20% more Met, Thr, and Trp relative to Lys on an apparent ileal digestible basis compared with the basal diet type. Pigs were followed for a complete fattening period and slaughtered at a targeted pen weight of 110 kg. Haptoglobin concentrations in serum (0.92 g/L for LSC and 0.78 g/L for HSC) and IgG antibody titers against keyhole limpet hemocyanin (3.53 for LSC and 3.08 for HSC) collected in the starter, grower, and finisher phases and pleuritis scores at slaughter (0.51 for LSC and 0.20 for HSC) were greater for LSC pigs compared with HSC pigs ( ≤ 0.01), illustrating that sanitary conditions affected health conditions. The ADG and G:F were greater for HSC pigs compared with LSC pigs ( ≤ 0.01). The number of white blood cells (WBC) was higher in (AA-S)-fed pigs compared with (AA-B)-fed pigs when kept at LSC but not at HSC [SS (sanitary conditions) × AA interaction, = 0.04]. Pigs fed NP had a lower number of WBC compared with pigs fed LP ( = 0.02). The number of platelets in pigs fed AA-S diets was higher compared with pigs fed AA-B diets ( ≤ 0.01). A 20% reduction in dietary supplementation of Met, Thr, and Trp relative to Lys decreased G:F more in LSC pigs than in HSC pigs

    Knowledge of the presence and extent of bone infiltration is crucial for planning the resection of potential bone-infiltrating squamous cell carcinomas of the head and neck (HNSCC). Routinely, plain-film radiography, multislice computed tomography (MSCT) and magnetic resonance imaging (MRI) are used for preoperative staging, but they show relatively high rates of false-positive and false-negative findings. Scintigraphy with {sup 99m}Tc-bisphosphonate has the ability to show increased metabolic bone activity. If combined with anatomical imaging (e.g. (SPECT)/CT), it facilitates the precise localization of malignant bone lesions. The aim of this study was to analyse the indications and advantages of SPECT/CT compared with standard imaging modalities and histology with regard to specificity and sensitivity A longitudinally evaluated group of 30 patients with biopsy-proven HNSCC adjacent to the mandible underwent {sup 99m}Tc-bisphosphonate SPECT/CT, MRI, MSCT and conventional radiography before partial or rim resection of the mandible was performed. Bone infiltration was first evaluated with plain films, MSCT and MRI. In a second reading, SPECT/CT data were taken into account. The results (region and certainty of bone invasion) were evaluated among the different imaging modalities and finally compared with histological specimens from surgical resection as the standard of reference. For a better evaluation of the hybrid property of SPECT/CT, a retrospectively evaluated group of 20 additional patients with tumour locations similar to those of the longitudinally examined SPECT/CT group underwent SPECT, MSCT and MRI. To assess the influence of dental foci on the specificity of the imaging modalities, all patients were separated into two subgroups depending on the presence or absence of teeth in the area of potential tumour-bone contact. Histologically proven bone infiltration was found in 17 patients (57 %) when analysed by conventional imaging modalities. SPECT/CT data

    Pollutant characteristics of surface runoff, sanitary sewage and sewer deposits from a combined sewer system in Shanghai were studied. It was confirmed that the content of Zn, NH4(+) -N, P, respectively in surface runoff, sanitary sewage and sewer deposits was specific and relatively stable based on contrasting pollutant characteristics of different sources. Three non-dimensional parameters-Zn/P, NH4(+) -N/Zn, P/K were proposed as characteristic index for surface runoff, sanitary sewage and sewer deposits. In order to find sources of pollutants in CSO, the application of chemical mass balance method was discussed: the average contributions to CSO were 42.8% for surface runoff, 12.2% for sanitary sewage, 23.8% for sewer deposits, and the results basically reflected the composition of CSO pollution. The research method and results can provide guidance for pollutant source apportionment of combined sewer overflows.

    Size-resolved bacterial concentrations in atmospheric aerosols sampled by using a six stage viable impactor at rice field, sanitary landfill, and waste incinerator sites were determined. Culture-based and Polymerase Chain Reaction (PCR) methods were used to identify the airborne bacteria. The culturable bacteria concentration in total suspended particles (TSP) was found to be the highest (848 Colony Forming Unit (CFU)/m(3)) at the sanitary landfill sampling site, while the rice field sampling site has the lowest (125 CFU/m(3)). The closed landfill would be the main source of the observed bacteria concentration at the sanitary landfill. The rice field sampling site was fully covered by rice grain with wetted conditions before harvest and had no significant contribution to the airborne bacteria concentration. This might occur because the dry conditions favor suspension of soil particles and this area had limited personnel and vehicle flow. The respirable fraction calculated by particles less than 3.3 mum was highest (26%) at the sanitary landfill sampling site followed by waste incinerator (19%) and rice field (10%), which showed a lower level of respiratory fraction compared to previous literature values. We identified 58 species in 23 genera of culturable bacteria, and the Microbacterium, Staphylococcus, and Micrococcus were the most abundant genera at the sanitary landfill, waste incinerator, and rice field sites, respectively. An antibiotic resistant test for the above bacteria (Micrococcus sp., Microbacterium sp., and Staphylococcus sp.) showed that the Staphylococcus sp. had the strongest resistance to both antibiotics (25.0% resistance for 32 microg ml(-1) of Chloramphenicol and 62.5% resistance for 4 microg ml(-1) of Gentamicin).

    The Savannah River Site (SRS) is a Department of Energy (DOE) facility located near Aiken, South Carolina which is currently operated and managed by Westinghouse Savannah River Company (WSRC). The Sanitary Landfill (Sanitary Landfill) at the SRS is located approximately 2,000 feet Northwest of Upper Three Runs Creek (UTRC) on an approximately 70 acre site located south of Road C between the SRS B-Area and UTRC. The Sanitary Landfill has been receiving wastes since 1974 and operates as an unlined trench and fill operation. The original landfill site was 32 acres. This area reached its capacity around 1987 and a Northern Expansion of 16 acres and a Southern Expansion of 22 acres were added in 1987. The Northern Expansion has not been used for waste disposal to date and the Southern Expansion is expected to reach capacity in 1992 or 1993. The waste received at the Sanitary Landfill is predominantly paper, plastics, rubber, wood, metal, cardboard, rags saturated with degreasing solvents, pesticide bags, empty cans, and asbestos in bags. The landfill is not supposed to receive any radioactive wastes. However, tritium has been detected in the groundwater at the site. Gross alpha and gross beta are also evaluated at the landfill. The objectives of this modeling study are twofold: (1) to create a local scale Sanitary Landfill flow model to study hydraulic effects resulting from capping the Sanitary Landfill; and (2) to create a Sanitary Landfill local scale transport model to support ACL Demonstrations for a RCRA Part B Permit Renewal.

    There are conflicting results on the growth and health of weanling pigs (Sus scrofa) fed high-fiber diets, and responses may differ according to sanitary conditions. This study was conducted to explore the growth, health, and fecal microbiota of weanling pigs fed either low- or high-fiber diets in 2 different sanitary conditions. Forty-eight pigs weaned at 28 d of age were individually housed in "good" (clean) or "poor" (unclean) sanitary conditions. During 2 consecutive phases, pigs were fed 2 diets containing a low (control) or high level of fiber: 121 or 169 g/kg total dietary fiber (TDF) for Phase I and 146 or 217 g/kg for Phase II, which lasted 15 and 20 d, respectively. This led to 4 experimental treatments in Phase I in a 2 × 2 factorial arrangement (2 sanitary conditions × 2 diets) and 8 experimental treatments in Phase II in a 2 × 2 × 2 factorial arrangement (2 sanitary conditions × 2 diets in Phase I × 2 diets in Phase II). The poor sanitary conditions led to a reduced G:F (0.617 vs. 0.680 for poor and good sanitary conditions, respectively; P = 0.01) over the entire experimental period. The number of pigs with diarrhea in Phase I tended to be greater in the poor sanitary conditions with the high-fiber diet than the control diet (7 vs. 3 pigs, P = 0.07). Enterococcus was prominent in feces of these diarrheic pigs. At 5 wk after weaning, compared with good sanitary conditions, the fecal microbiota of pigs housed in poor sanitary conditions was characterized by more Lactobacillus (9.24 vs. 8.34 log cfu/g, P pigs in poor sanitary conditions contained more total VFA and proportionally more butyrate (9.7 vs. 5.7% for poor and good conditions, respectively, independently of dietary treatment, P pigs fed the high-fiber diet during Phase II contained less Enterococcus bacteria than pigs fed the control diet (4.06 vs. 4.56 log cfu/g; P = 0.05), and more total VFA with a decreased proportion of branched-chain fatty acids (5.0 vs. 6.1%; P = 0.006).

    Full Text Available Landfill gases (LFG are produced due to biodegradation of organic fraction of municipal solid waste (MSW when water comes in contact with buried wastes. The conventional clay cover is still practiced to mitigate the percolation of water in landfills in India. Gas extraction systems in landfill for gas collection are used but are much expensive. Thus, “Phytocapping” technique can be one of the alternatives to mitigate landfill gases and to minimize percolation of water into the landfill. Indian plants with locally available soil and municipal solid waste can be tested for the purpose of methane mitigation, heavy metals remediation from leachate. Methane oxidation due to vegetation can be observed compared to non-vegetated landfill. Root zone methane concentrations can be monitored for the plant species.

In the newly-developed technique,a negative pulsed voltage,with respect to the vacuum chamber,was applied to the target so as to re-accelerate the impinging ions;and the conventional ion implantation was combined with plasma ion implantation.The various influencing factors,including the time evolutions of the field distribution above the negatively biased target surfaces,ion density distribution and ion trajectories,were modeled and simulated with 2-D software package particle-in-cell. The distributions of the implantation dosage,energy and incident angle of the ions at different times were statistically evaluated. The simulated results show that the negative bias significantly accelerates the ion for a second time,and the technique has a sold theoretical basis. Besides,the field distribution,originated from the bias,slightly bends the ion beam in such a way that its cylindrical shape changes into a bell-like one,considerably increasing the

    Hans Reichenbach famously argued that the geometry of spacetime is conventional in relativity theory, in the sense that one can freely choose the spacetime metric so long as one is willing to postulate a "universal force field". Here we make precise a sense in which the field Reichenbach defines fails to be a "force". We then argue that there is an interesting and perhaps tenable sense in which geometry is conventional in classical spacetimes. We conclude with a no-go result showing that the variety of conventionalism available in classical spacetimes does not extend to relativistic spacetimes.

    The field experiment was conducted by using a randomized complete block design to investigate the effects of different dosages coated controlled release urea(CRU) combined with conventional urea (U) used as basal application on the growth and development, grain yield, nitrogen uptake and utilization of winter wheat in this study. Five treatments were set, i.e. control (CK), 100% U (T1), 100% CRU (T2), 80% CRU + 20% U (T3), 60% CRU + 40% U (T4). The results showed that the 1000-grain weight, grain number per ear, harvest index and grain yield were significantly increased in the treatments of T3 and T4 compared with T1 treatment in the same N -application. The grain yield of winter wheat was increased by 7. 42% -13. 12%. Besides, in comparison with the T1 treatment, the amount of nitrogen accumulation in wheat grain was increased and the amount of residual nitrogen in vegetative organs was reduced at the mature stage in treatments T3 and T4. The nitrogen use efficiency were increased by 8. 37% ~ 14. 05% and the soil nitrogen dependency ratio was reduced by 7. 43% -11. 04% in these two treatments. Composite application of controlled-release urea and traditional urea could reduce fertilizer costs to some extent and improve the economic efficiency. In this study, the T4 treatment was recommended as the appropriate combination of controlled - release urea and traditional urea for the high grain yield, nitrogen use efficiency and maximum economic benefits.%采用完全随机区组设计,通过田间试验研究不同量的控释尿素(CRU)与普通尿素(U)配合基施(100%U,T1;100% CRU,T2;80% CRU+20%U,T3;60% CRU+40%U,T4)对冬小麦生长发育、产量及氮素吸收利用的影响.结果表明,在施氮量相等条件下,控释尿素与普通尿素配施处理(T3和T4)冬小麦千粒重、穗粒数和收获指数与单施尿素(T1)相比显著增加,冬小麦产量提高7.42%~13.12%;此外,两种尿素配施能增加冬小麦成熟期籽粒中

    The article presents the history of Polish sanitary and epidemiological services from 1918 until contemporary times. Emphasizing many achievements of National Sanitary Inspectorate, which are responsible for the low sick-rate of infectious diseases in Poland, the article also points to the increasing number and growing severity of environmental hazards in recent years. The article discusses problems caused by the "old" infectious diseases, which, though until recently regarded as passed, are posing threats to the society nowadays (e.g. TB, pestis, cholera). Equally, the article highlights problems caused by the "new" highly infectious diseases (e.g. Ebola fever, AIDS). Moreover, the article focuses on the particularly relevant subject of tackling biological weapons, the use of which can be traced past the recent events after September 11 and back to the Middle Ages. Finally, the article stresses the role of sanitary and epidemiological services in fighting recent animal epidemics, such as foot-and-mouth disease and mad cow disease. Discussing particular cases of the environmental hazards mentioned above, recorded in Poland, the article emphasizes the importance of the proper staff selection for National Sanitary Inspectorate. In the past decade in Poland, Sanitary Inspectors were selected mostly with regard to their political orientation, rather than their professional background. The author of the article hopes that human life and health will be treated with more respect in Poland in the neart future and the positions of Sanitary Inspectors will be given to professionals with proper epidemiological preparation. Radical changes in the policy of staff selection, modernization of training programs, as well as creation of a more practical structure of National Sanitary Inspectorate are the necessary conditions for transforming sanitary and epidemiological services in Poland into reliable and prestigious institutions, capable of dealing with the environmental hazards

    2007-12-01

    Increased atmospheric concentrations of greenhouse gases (GHG) caused by anthropogenic activities has been related to global climate change. Methane, the second most important GHG after CO2, is 21 times more effective at trapping heat than CO2. Therefore, methane emission control is of utmost importance for global warming reduction. To minimize leachate production and protect groundwater resources, modern sanitary landfills are equipped with composite covers and gas collection systems. Methane from modern sanitary landfills is vented directly to the atmosphere, except for some of the largest landfills where it is recovered as energy and burned at the site. However, the efficiency of energy recovery systems in larger landfills is reduced as the amount of CH4 generated from landfill begins to decrease. In this study, the performance of a lab-scale model biofilter system was investigated to treat CH4 gas emitted from modern sanitary landfills by conducting batch and column experiments using landfill cover soil amended with earthworm cast as the filter bed medium. From the batch experiments to measure the influence of moisture content and temperature of the filter medium on CH4 removal capacity of a biofilter system, the optimum moisture content and temperature were found to be 10-15% by weight and 25-35°C, respectively. The column experiment was conducted to measure the influence of inlet CH4 concentration and CH4 loading rate on CH4 removal capacity of a biofilter system. As the inlet CH4 concentration decreased, the percentage of CH4 oxidized increased. Up to a CH4 loading rate of 2785 g CH4 m3 h- 1 (EBRT = 7.7 min), the CH4 removal efficiency of the biofilter was able to reach 100%. Based on the results of the study, the installation of a properly managed biofilter system should be capable of achieving a reduction in atmospheric CH4 emissions from modern sanitary landfills at low CH4 generation stage.

    Sanitary and environmental regulations may have indirect effects on the wildlife and ecosystem services beyond their regulatory scope. To illustrate such effects, this paper examines how EU sanitary measures, in conjunction with additional regulations and socio-economic changes, have caused wolf diet to shift in Galicia, northwestern Spain. Prior to the bovine spongiform encephalopathy (BSE) crisis in Europe in 2000, livestock carcasses used to be left on the field and were eaten by scavengers and carnivores. As a result of the BSE crisis, sanitary regulations regarding the disposal of livestock carcasses were introduced. These regulations affected the populations of avian scavengers. We hypothesize that wolf ecology has also been affected by the aforementioned regulations. We analysed wolf diet for the period 2003-2006 and compared the results with those of a previously published study (1974-1978). We found a shift in wolf feeding habits following the implementation of these EU regulations. A decrease in carrion consumption was registered, and wolves increased their feeding on the rising population of wild ungulates, especially on roe deer, and on wild pony. Future regulations should assess their potential indirect effects in the early stages of drafting to allow for the design of proper mitigation measures.

    Full Text Available The three main ingredients of sanitary-ware are clay, feldspar and quartz. This ware is being widely used and has therefore, attracted the attention of researchers from time to time. Consequently, it has been extensively investigated. The present study describes the phase and micro-structural analysis of sanitary-ware samples collected from local (Durr Ceramics Peshawar industry. XRD (X-Ray Diffraction of samples fired at 1100oC reveals the presence of ? ? ? ? ?-quartz and primary mullite only. In addition to a-quartz and primary mullite, elongated needles of secondary mullite were also present in samples fired at 1200 and 1300oC. Unlike typical vitreous ceramics bodies, regions containing elongated secondary mullite originating from the clay relict and growing into the feldspar relict were few in number which is consistent with the high clay content in the starting body ingredients of the investigated samples. Another sample investigated for comparison purposes, contained all the phases mentioned above along with some corundum grains which indicated that the composition of sanitary ware varied from manufacturer to manufacturer. EDS (Energy Dispersive Spectroscopy detected high concentration of Fe in some regions in the bulk but the glaze did not contain any Fe.

    Full Text Available OBJECTIVE: Odorous compounds produced at the biosolids composting plant in Bariloche (NW Patagonia attract a variety of insects, mainly belonging to the order Diptera. In order to characterize these flies, collected specimens were taxonomically identified, their community characteristics were described and their sanitary and synanthropic importance and autochthonous or introduced character were determined. METHODS: Sampling was performed from October 1999 until March 2000. Adults were collected using an entomological net, and larvae and puparia were obtained from the composting material and incubated to obtain adults. Richness, abundance and sex ratio were calculated. RESULTS: A total of 9 taxa of Diptera were identified: Sarconesia chlorogaster, Phaenicia sericata, Calliphora vicina, Cochliomya macellaria, Ophyra sp, Muscina stabulans, Musca domestica, Sarcophaga sp and Fannia sp. Specimens of Anthomyiidae, Acaliptratae and one larva of Eristalis tenax were also found. Ophyra sp. was the most abundant taxa. All the captured Diptera belonged to introduced taxa. Most of them are considered to be eusynanthropic and/or hemisynanthropic and have sanitary importance as they may cause myiasis and pseudomyiasis. The high number of females registered and the finding of immature stages indicated that flies can develop their complete life cycle on biosolid composting windrows. CONCLUSIONS: The characterization of flies obtained in this study may be useful for defining locations of urban or semi-urban composting facilities. It also highlights the importance of sanitary precautions at such plants.

    The efficacy of directly killing tumors by conventional cancer therapies, such as chemotherapy and radiotherapy, has been for several decades well established. But, a suppressed immune response might become a lethal side effect after repeated cycles of intensive treatment. Recently, achievements in immune checkpoint inhibitors and adoptive T cell-mediated immunotherapies have resulted in changes in frontline management of advanced cancer diseases. However, accumulated evidence indicates that immunotherapeutic and conventional strategies alone are often ineffective to eradicate big tumors or metastasis. To improve the outcomes of treatment for advanced cancer diseases, the combination of conventional cancer treatment with various immunotherapeutic approaches has been attempted and has shown potential synergistic effects. Recent studies have unexpectedly demonstrated that some strategies of conventional cancer treatment can regulate the immune response positively, thus the understanding of how to adapt conventional treatment for immunotherapy is crucial to the design of effective combination therapy of conventional treatment with immunotherapy. Here, we review both experimental and clinical studies on the therapeutic effect and its mechanisms of combining conventional therapy with immunotherapy in treatment of cancer.

    Full Text Available The objective of this study was to investigate the efficiency of germicidal lamps in the tertiary treatment of sewage to control pathogens. The performance of the photochemical reactor used in the tests was monitored by microbiological analyses to quantify E. coli (bacteria indicator, C. perfringens (protozoa indicator, coliphages (virus indicator. The experiments were performed with effluent from an UASB reactor installed at the WTP- USP São Carlos campus subjected to an aerated submerged biological filter and a photochemical reactor with radiation UV at 254 nm. The results showed that the indicators coliphages and E. coli showed the least resistance to UV radiation reaching removal from 1.70 to 3.90 log and 1.60 to 5.20 log, respectively. On the other hand, the indicator C. perfringens was more resistant to the effect of germicidal lamps reaching values between 0.0 (no inactivation and 1.30 log. For SST concentrations greater than 100.0 mg.L-1, the effect of the germicidal lamps became less pronounced. However, in practice it was possible to notice significant results in tests with TSS concentrations of 135.0 mg.L-1. The experimental approach proved the usefulness of the combined method for inactivating pathogens commonly found in domestic sewage. Besides meeting the standards established by the Brazilian regulation, the final effluent is in agreement with the guidelines defined by WHO. This allows the reuse of the final effluent for unrestricted irrigation, although complementary examination must be performed.

    Conventional cerebrospinal fluid scanning (CSF scanning) today is mainly carried out in addition to computerized tomography to obtain information about liquor flow kinetics. Especially in patients with communicating obstructive hydrocephalus, CSF scanning is clinically useful for the decision for shunt surgery. In patients with intracranial cysts, CSF scanning can provide information about liquor circulation. Further indications for CSF scanning include the assessment of shunt patency especially in children, as well as the detection and localization of cerebrospinal fluid leaks.

    Full Text Available Five durum wheat cultivars were grown in a Mediterranean area (Southern Italy under conventional and organic farming with the aim to evaluate agronomic, technological, sensory, and sanitary quality of grains and pasta. The cultivar Matt produced the best pasta quality under conventional cropping system, while the quality parameters evaluated were unsatisfactory under organic farming. The cultivar Saragolla showed the best yield amount and pasta quality in all the experimental conditions, thus proving to be the cultivar more adapt to organic farming. In all the tested experimental conditions, nivalenol (NIV and deoxynivalenol (DON occurrence was very low and the other mycotoxins evaluated were completely absent. These data confirm the low risk of mycotoxin contamination in the Mediterranean climate conditions. Finally, it has been possible to produce high-quality pasta in Southern Italy from durum wheat grown both in conventional and organic farming.

    The terms "alternative" or "unconventional" have been used to describe any therapy used instead of conventional approaches. Conventional approaches, known as "standard" or "traditional" or "biomedical" approaches, have had broad application in Western medicine. Complementary and alternative medicine has been referred to as "integrative," "integrated," or "complementary" when therapies are combined with conventional approaches, such as those for cancer.

    Parabens (alkyl esters of p-hydroxybenzoic acid) are widely used as antimicrobial preservatives in personal care products, pharmaceuticals, and foodstuffs. Although parabens have been reported to be used as antimicrobials in certain types of papers (e.g., wet sanitary or hygiene wipes), little is known about the occurrence of these compounds in paper products. In this study, we determined the concentrations of six paraben analogs, methyl (MeP), ethyl (EtP), propyl (PrP), butyl (BuP), benzyl (BzP), and heptyl parabens (HepP), in 253 paper products divided into 18 categories, using liquid chromatography-tandem mass spectrometry (LC-MS/MS). At least one of the six parabens was detected in almost all (detection rate: 98%) paper samples, and the total concentrations (∑PBs; sum of six parabens) ranged from 1.85 to 3,220,000 ng/g (geometric mean (GM): 103; median: 55.1 ng/g). Sanitary wipes contained very high concentrations of ∑PBs (GM: 8300 ng/g). Paper currencies, tickets, business cards, food cartons, flyers, and newspapers contained notable concentrations of ∑PBs, and the GM concentrations in these paper categories were on the order of a few tens to thousands of nanograms per gram. One source of parabens in paper products is the use of these chemicals as antifungal agents. MeP and PrP were the predominant analogs, accounting for approximately 62% and 16% of the total concentrations of parabens, respectively. On the basis of measured concentrations and frequency of handling of paper products, we estimated the daily intake (EDI) of parabens through dermal absorption. The GM and 95th percentile EDI values were 6.31 and 2050 ng/day, respectively, for the general population. Among the paper categories analyzed, sanitary wipes contributed to the majority (>90%) of the exposures.

    We are updating a CH2M Hill study which found that the sanitary sewer system is sufficient to transport peak dry weather flow. However, under peak wet weather conditions, the system has insufficient capacity to transport the projected flows for existing and future development. This is due to the amount of infiltration/inflow (I/I) that enters the sewer system when it rains. Our goal is to examine the existing system to determine its adequacy to accommodate present and future peak flows, and also to further update and improve the CH2M Hill study. A set of alternatives was also developed to address deficiencies of the existing system.

    In 1991, a soil gas survey was performed at the Savannah River Site Sanitary Landfill as part of the characterization efforts required under the integrated Resource Conservation and Recovery Act (RCRA) Facility Investigation and Comprehensive Environmental Resource Conservation and Recovery Act (CERCLA) Remedial Investigation (RFI/RI) program. This report details the findings of this survey, which identified several areas of the landfill that were releasing volatile organic compounds to the atmosphere at levels exceeding regulatory standards. Knowledge of the rates of VOC outgassing is necessary to protect site workers, provide input into the human health and environmental risk assessment documents and provide input into the remedial design scenario.

    The pollution of particulates origin is one of the principle actual problem relative to air quality. In France, the fine particulates come from industry and automobile traffic, especially, the diesel vehicles. The most worrying characteristic is their fineness, that allow them to stay in suspension during a long time and penetrate into pulmonary alveoli, with toxic elements at their surface such metals, acids, polycyclic aromatic hydrocarbons. The objective of this work is to take stock of epidemiology and toxicology studies evaluating the sanitary impact of particulates in suspension. (N.C.)

    The Savannah River Site (SRS) has proposed a new sanitary landfill (NSL) for solid waste. A site selection team, comprised of representatives from Westinghouse Savannah River Company (WSRC) evaluated potential landfill sites. The site selection team conducted an initial screening of SRS to eliminate unsuitable areas. The screening was based on criteria that were principally environmental factors; however, the criteria also included avoiding areas with unacceptable features for construction or operation of the facility. This initial screening identified seven candidate sites for further evaluation.

    Sanitary challenges negatively affect feed intake and growth, leading to a negative impact on animal well-being and economic losses. The aim of this study was to carry out a meta-analysis to quantify the dynamic feed intake and growth responses of growing pigs after a sanitary challenge. A database was constructed using 122 published experiments reporting the average daily feed intake (ADFI) and the average daily gain (ADG) of pigs subjected to one of six sanitary challenges: digestive bacterial infections, poor housing conditions, lipopolysaccharide (LPS) challenges, mycotoxicoses, parasitic infections and respiratory diseases. The responses to experimental challenges were calculated relative to that of a control group. Statistical analyses were carried out for each challenge to quantify the mean and the dynamic responses in feed intake and growth and to identify the basis of the reduction in growth (i.e. reduction in feed intake or reduction in feed efficiency related to changes in maintenance requirements). All challenges resulted in a reduction in ADFI and ADG, with the strongest responses for mycotoxicoses, respiratory diseases and digestive bacterial infections (8% to 23% reduction in ADFI and 16% to 29% reduction in ADG). The reduction in ADG was linearly related to the reduction in ADFI for digestive bacterial infections, LPS challenge, parasitic infections and respiratory diseases. For poor housing conditions and mycotoxicoses, the relationship was curvilinear. A 10% reduction in ADFI resulted in a reduction in ADG varying from 10% for mycotoxicoses to 43% for digestive bacterial infections. More than 70% of the reduction in ADG could be explained by the reduction in ADFI for mycotoxicoses, LPS challenge and respiratory diseases. For challenges associated with the gastrointestinal tract, a large part of the reduction in ADG was due to an increase in maintenance requirements, suggesting digestive and metabolic changes. A dynamic pattern in the reduction in

    The calculation of a sanitary impact present a great interest at the decision level for the decision-makers and the whole of concerned actors. It constitutes a first step to organize a social debate around the risk acceptance, to analyze the feasibility of an inquiry or an epidemiological surveillance or to proportion an activity leading to pollutants emission in natural medium. Several conclusions are brought out: it is justified to estimate a sanitary impact from a sanitary risk excess, especially coming from animal tissue. It is conceivable to go beyond an estimation of the only individual risk and to calculate a number of cases in excess in the concerned population. The working group underlines that the characteristics of the situation are the determining factor to give the type of response to bring. The effective of the population is an important element and a situation has not to be underestimated because of the size at the pretext that the excess calculation leads to a number of cases inferior to one leading to believe that the impact is minor or negligible while the individual probability is high. The sanitary impact, expressed by the number of cancer cases in excess in an exposed population is quantified from the average value of excess of sanitary risk multiplied by the population effective, and expressed with a confidence interval. The sanitary impact can be expressed under the form of a percentage of the population present in the exposure area and goes past the comparison marks usually pointed up. This practice must be cheered. An analysis of uncertainties must be made as often as possible. (N.C.)

    The international experience gained during the past two centuries indicates that the most efficient and rational way to ensure the protection of the territories occupied by the therapeutic and health-promotion facilities, spa centres, and health resorts together with their natural medical resources is to set up sanitary (mountainous sanitary) protection districts or zones along the perimeter of these territories. Beginning from 2000, numerous changes and amendments have been annually introduced in the Russian legislation intended to ensure efficacious control over the rational exploitation of the territories of therapeutic and health-promotion value and their natural medical resources. These initiatives have negative effect on the activities of these organizations and the quality of the services they are expected to provide. Taken together these effects lead to the degradation of the spa and health resort business. Bearing in mind the current conditions for economic activities, it is proposed, in contrast to the former global approach, to envisage in the aforementioned projects the establishment of the sanitary (mountainous sanitary) protection districts or zones and determine their borders based on the results of the assessment of their potential for the protection of therapeutic factors and other valuable resources. Equally important is the maximum reduction of the areas of the second and third zones taking into account their relevant objective characteristics. In certain cases, the protective district may coincide with the second zone. As far as the federal health resorts and large territories of special health-promotion value are concerned, some of them may have two or more sanitary (mountainous sanitary) protection districts. Both the owners and the users of these territories should be provided the necessary and sufficient possibilities for the rational nature use at the grounds and in the adjacent water areas suitable for the development of health resort

    Perfluorooctane sulfonate (PFOS) and perfluorooctanoate (PFOA) are two emerging contaminants that have been detected in all environmental compartments. However, while most of the studies in the literature deal with their presence or removal in wastewater treatment, few of them are devoted to their detection in treated drinking water and fate during drinking water treatment. In this study, analyses of PFOS and PFOA have been carried out in river water samples and in the different stages of a drinking water treatment plant (DWTP) which has recently improved its conventional treatment process by adding ultrafiltration and reverse osmosis in a parallel treatment line. Conventional and advanced treatments have been studied in several pilot plants and in the DWTP, which offers the opportunity to compare both treatments operating simultaneously. From the results obtained, neither preoxidation, sand filtration, nor ozonation, removed both perfluorinated compounds. As advanced treatments, reverse osmosis has proved more effective than reverse electrodialysis to remove PFOA and PFOS in the different configurations of pilot plants assayed. Granular activated carbon with an average elimination efficiency of 64±11% and 45±19% for PFOS and PFOA, respectively and especially reverse osmosis, which was able to remove ≥99% of both compounds, were the sole effective treatment steps. Trace levels of PFOS (3.0-21 ng/L) and PFOA (water were significantly lowered in comparison to those measured in precedent years. These concentrations represent overall removal efficiencies of 89±22% for PFOA and 86±7% for PFOS.

    Full Text Available The scope of the paper is to review the literature that employs coordination games to study social norms and conventions from the viewpoint of game theory and cognitive psychology. We claim that those two alternative approaches are in fact complementary, as they provide different insights to explain how people converge to a unique system of self-fulfilling expectations in presence of multiple, equally viable, conventions. While game theory explains the emergence of conventions relying on efficiency and risk considerations, the psychological view is more concerned with frame and labeling effects. The interaction between these alternative (and, sometimes, competing effects leads to the result that coordination failures may well occur and, even when coordination takes place, there is no guarantee that the convention eventually established will be the most efficient.

    El objetivo de este artículo es presentar la literatura que emplea los juegos de coordinación para el estudio de normas y convenciones sociales, que se han analizado tanto desde el punto de vista de la teoría de juegos como de la psicología cognitiva. Argumentamos en este trabajo que estos dos enfoques alternativos son en realidad complementarios, dado que ambos contribuyen al entendimiento de los procesos mediante los cuales las personas llegan a coordinarse en un único sistema de expectativas autorrealizadas, en presencia de múltiples convenciones todas ellas igualmente viables. Mientras que la teoría de juegos explica la aparición de convenciones basándose en argumentos de eficiencia y comportamientos frente al riesgo, el enfoque de la psicología cognitiva utiliza en mayor medida consideraciones referidas al entorno y naturaleza de las decisiones. La interacción entre estos efectos diferentes (y en ocasiones, rivales desemboca con frecuencia en fallos de coordinación y, aun cuando la coordinación se produce, no hay garantía de que la convención en vigor sea la m

    The WHO Consensus Document on the epidemiology of the SARS epidemic in 2003, included a report on a concentrated outbreak in one Hong Kong housing block which was considered a ‘super-spreading event’. The WHO report conjectured that the sanitary plumbing system was one transmission route for the virus. Empty U-traps allowed the aerosolised virus to enter households from the sewerage system. No biological evidence was presented. This research reports evidence that pathogens can be aerosolised and transported on airstreams within sanitary plumbing systems and enter buildings via empty U-traps. A sanitary plumbing system was built, representing two floors of a building, with simulated toilet flushes on the lower floor and a sterile chamber with extractor fan on the floor above. Cultures of a model organism, Pseudomonas putida at 106–109 cfu ml-1 in 0·85% NaCl were flushed into the system in volumes of 6 to 20 litres to represent single or multiple toilet flushes. Air and surface samples were cultured on agar plates and assessed qualitatively and semi-quantitatively. Flushing from a toilet into a sanitary plumbing system generated enough turbulence to aerosolise pathogens. Typical sanitary plumbing system airflows (between 20–30 ls-1) were sufficient to carry aerosolised pathogens between different floors of a building. Empty U-traps allowed aerosolised pathogens to enter the chamber, encouraging cross-transmission. All parts of the system were found to be contaminated post-flush. Empty U-traps have been observed in many buildings and a risk assessment indicates the potential for high risk cross-transmission under defect conditions in buildings with high pathogen loading such as hospitals. Under defective conditions (which are not uncommon) aerosolised pathogens can be carried on the airflows within sanitary plumbing systems. Our findings show that greater consideration should be given to this mode of pathogen transmission. PMID:28187135

    Full Text Available Currently, tariffs do not represent the main barrier to foreign trade, due to the continued reduction of these measures in the multilateral or bilateral level. In contrast, non-tariff measures have increased to be considered as the main concern for exports. In this context, one kind of such measures becomes more important, the sanitary and phytosanitary (SPS measures. SPS measures serve to protect the health of people, animals and plants against risks associated with diseases, pests between others; however, by the design of those measures, they can distort trade or even been used for protectionist purposes in favor of national industries of importing countries. This article questions whether Peru has achieved real market access for its agricultural and fishery products, because of the wide range of international trade agreements in force. In this sense, historical and pending cases are presented in terms of market access due to SPS measures, like the access for Peruvian avocadoes In the Japanese market. Furthermore, the provisions of trade agreements in terms of sanitary and phytosanitary measures are analyzed in order to present potential opportunities that are established in these agreements and how they encourage trade. It is also presented that those kind of measures have not been used to facilitate Peruvian foreign trade.

    Full Text Available In order to analyze the ecological unbalance that affects a city like Quito, marked by an anarchic urban growth and problems on its environmental quality, it is interesting to relate three “Good Living” factors: Health, Education and Environment. There are numerous ways to establish links. Under this thought, based on scientific studies and public policies, we have defined to concrete facts: the impact of the environment on the health of the public and the possibility of reducing sanitary risks thru education. The economical, political and cultural dynamics of the Ecuadorian Capital could encourage the elaboration of programs and actions toward a better environmental and sanitary education. Which are the strategies, from the Municipal authorities, to create a collective dynamism that will take the population to become aware of the natural and anthropological risks? Many efforts have been realized to determine the natural threats, but little has been done in order to analyze the impact of the decay of the environment over our health. There are many different initiatives to sensitize the population on these risks. Nevertheless, there is a still lot to do with respect to the dissemination and follow up of programs and projects that are being carried out on the Distrito Metropolitano de Quito.

    Full Text Available The objective of this research was to evaluate the effects of using different herbicides as desiccants in pre - harvest and the effects of storage on the physiological and sanitary quality of azuki bean seeds ( Vigna angularis Willd. The experiment was arranged in a randomized complete block design in a split plot scheme, with four replications. Four herbicides were tested: paraquat (400 g a.i. ha - 1 , glufosinate ammonium (400 g a.i. ha - 1 , glyphosate (720 g a.i. ha - 1 , flumioxazin (30 g a.i. ha - 1 and a control without herbicide application. In the subplots seed quality was tested in two evaluation periods: at harvest and six months after harvest. Desiccant was applied when the azuki beans were physiologically mature. We assessed the physiological and sanitary quality of the seeds using a vigour and seed health test. The use of glyphosate resulted in a higher incidence of abnormal seedlings and reduced size and weight of the seedlings. With paraquat and flumioxazin the physiological quality was maintained and there was reduced pathogen infestation in the seeds six months after harvest. Storage affected the physiological quality of the azuki bean seeds.

    Full Text Available Soybean production accounts for approximately 43% of Brazil’s grain produce, worth over 81 million tons for the 2012- 2013 cropping season. The use of quality seeds is essential for a high-yield agriculture, since low quality seeds compromise plant standing and increase production costs due to reseeding. This will in turn reduce yields through delays on the establishment dates. Seed quality is affected by relative humidity levels, mechanical damage during harvest and processing, thermal damage during the drying process and the environmental conditions during storage that could foster insect and fungi damage. The climate in the state of Santa Catarina favors soybean seed production, and seed companies in general work with high levels of technology. This work is aimed at characterizing the physical and sanitary quality of soybean seeds produced by different companies at different locations throughout the state of Santa Catarina (municipalities of Xanxerê, Abelardo Luz, Campos Novos and Canoinhas. The physical purity, moisture level, sanitary quality and mechanical damage of soybean seeds were studied at three stages, i.e. reception at the seed processing unit, at the end of the processing process and before being marketed. Results pointed out at mechanical injury and cultivar mixture as the main issues concerning seed lot quality, and that soybean seeds produced in Santa Catarina show pathogen contamination, which emphasizes the need for seed treatment.

    Full Text Available Final disposal of solid waste is still a cause for serious impacts on the environment. In sanitary landfills, waste undergoes physical, chemical, and biological decomposition, generating biogas and leachate. Leachate is a highly toxic liquid with a very high pollution potential. The purpose of this work is to evaluate toxicity of in natura leachate samples collected from Limeira Sanitary Landfill, in Limeira, SP. The ecotoxicological evaluation comprised acute toxicity assays using as test organisms Daphnia Similis, seeds of Eruca sativa (arugula, and Allium cepa roots (onion. Analyses of color, pH, turbidity, conductivity, hardness, nitrogen, total organic carbon (TOC, adsorbable organic halogen (AOX, and metals were also carried out. The main results for Eruca sativa (arugula and Allium cepa (onion indicated that the diluted leachate 50% presented similar toxicity to the phenol solution of 1000 mg.L-1 for arugula and 2000 mg.L-1 for onion. With the solution of Cr+6 concentrations of 3000 mg.L-1 for arugula and 2000 mg.L-1 for onion were found. For analyses with Daphnia Similis the EC50 was 9.3% on average. This way it was possible to observe that biological tests are necessary to evaluate the pollution in the effluents or water bodies. These tests serve to determine the toxic potential of a chemical agent or complex mixture.

    Aim of this investigation is to identify possible sanitary risks connected with the practice of dentistry and to draw up guidelines which may help all those who work in this field. Between April and July 1998, we distributed 231 questionnaires to public and private dental offices in Milan, to evaluate dentists' knowledge of sanitary risks in their practices. One hundred and sixteen of the 231 distributed questionnaires were returned. All the dentists contacted, used protective measures such as gloves, masks, glasses, and high-speed aspirators. Survey responses indicated that the most readily transmittable infectious diseases in dentist's practices are, in order of importance, hepatitis, AIDS, airborne diseases, and herpes. Surgery, endodontics, and the use of sharp instruments most likely lead to transmission of pathogens in both patients and dentists. Dentist's knowledge of out-patient treatment is good whereas their knowledge of the use of disinfectants for dental equipment is poor. The latter suggests the utility of continuing education in this critical aspect of the practice of dentistry.

    Methyldibromo glutaronitrile (MDBGN) has rarely been reported as an allergen in adhesives but is recognized as a common allergen in skin care products in Europe. It has been banned for use in leave-on products by the European Union. In this study, we present a case with an unusual source of this common allergen and review all cases of allergy to MDBGN from our clinics over a 12-year period. A 49-year-old nurse presented with dermatitis affecting the vulva caused by MDBGN present in her sanitary pad. All other cases of allergy to MDBGN in patients attending the occupational dermatology or contact dermatitis clinics at the Skin and Cancer Foundation, Victoria, between January 1993 and December 2004, were reviewed. Patch testing was positive to her sanitary pad, the adhesive and MDBGN, which were used as a biocide in the pad adhesive. Only 20 cases of allergy to MDBGN have been diagnosed in 2837 patients tested during this period (0.7%). To conclude, this study highlights the importance of considering allergic contact dermatitis in the differential diagnosis of vulval rashes and the emergence of MDBGN as an important sensitizer. However, our review suggests that MDBGN remains an infrequent cause of allergy in Australia.

    Sanitary pads for menstrual hygiene have a layered design consisting of a fluid permeable surface (topsheet), an absorbent core, and an impermeable backing with adhesive. Most sanitary pads employ cellulose-based cores. This describes the safety evaluation of a menstrual pad with an emollient-treated topsheet and a novel polymeric foam core. A quantitative risk assessment was performed, which included: (1) toxicological evaluation of the raw material components; (2) quantitative exposure assessments of pad constituents, accounting for the fluid handling properties of the product and pertinent conditions of use; and (3) risk characterization for exposure to raw materials (e.g., potential for skin irritation, contact sensitization, or systemic effects, if relevant) and to the physical article itself (potential effects on skin friction, etc.). No significant risk of adverse effects was found. Five years of post-market surveillance substantiates that the product is well-tolerated (1 health complaint reported per 2 million products shipped to market) and surpasses women's expectations for menstrual protection and overall comfort and dryness. This report illustrates how the classical risk assessment paradigm, informed by the impact of product design, functionality and pertinent use conditions, allowed the systematic safety evaluation of a personal hygiene product with a novel, non-cellulosic absorbent foam core technology.

    Full Text Available Istrian Peninsula, one of the five districts within viticultural region of Coastal Croatia, provides great geological-reliefal and climatic diversity and various production conditions. This research studied the autochthonous varieties and their sanitary status in old vineyards. Considering the age of vineyard, ten locations were chosen where four autochthonous varieties ‘Malvasia istarska’, ‘Teran’, ‘Borgonja’, and ‘Pergola velika’ were identified using ampelographic description according to OIV descriptors. Morphological characteristics of chosen varieties were described using OIV parameters and must was chemically analysed (pH value, sugar content, titratable acidity. High intra cultivar variability was found for weight of a single bunch especially for ‘Teran’. There were also differences in sugar content of must particularly for ‘Pergola velika’. Must pH was low for all varieties with predominantly low acidity value. Sanitary status of vines was determined by testing the plant samples for the presence of three grapevine viruses (GLRaV-1, GLRaV-3 and GFLV using DAS-ELISA. The percentage of infection for GFLV was 55.6% while for GLRaV-1 and GLRaV-3 it was 61.1%. Results showed that some morphological characteristics differ from characteristics described in literature. With purpose of preserving the biodiversity of autochthonous varieties and for future researches, healthy propagation material will be collected and planted in collection field of autochthonous varieties at the Institute of Agriculture and Tourism, Poreč.

    Full Text Available This article presents a critical review of scientific literature on waste sanitary landfills and its effects on human health, with an approach to the adverse effects that are most commonly associated to living near waste landfills. The health variables included were low birth weight, congenital abnormalities, some types of neoplasms, allergies, asthma and other respiratory diseases using the MEDLINE, LILACS and CAPES’ thesis post graduation database for systematic review. In spite of the fact that some studies indicate positive asssociation between health risks and living close to landfills, the majority of the studies, mainly the most recent ones, do not demonstrate a significant health risk in this condition. Some common limitations and bias of the work in the field are discussed. The lack of direct quantification of exposure, lack of prospective approach and no comparaison of the different types and quality of management of the residues are common limitations to most studies. So far, there is weak evidence to support significant epidemiological health risks associated to landfills. More interdisciplinary research should improve the knoledge of the health risks related to living in the proximity to sanitary landfills.

    Phosphogypsum is a by-product of the phosphatic fertilizer production from the beneficiation of phosphate minerals (apatites). Produced in large quantities throughout the world and stored temporally in stacks, the final destination of this product is nowadays a subject of investigation. Due to the presence of radionuclides ({sup 226}Ra, {sup 232}Th and {sup 40}K, mainly), possible applications for the phosphogypsum must be verified for radiological safety. The goal of this paper was to elaborate a representative water flow conceptual model of a sanitary landfill for the safety assessment of the impact of using phosphogypsum as a cover material. For this, the ground water flow in variably saturated conditions and solute transport model HYDRUS-2D has been used for simulating the impact in the saturated zone of potential radionuclides leaching. The conceptual model was developed by collecting and analyzing the data from environmental license documentation of municipal sanitary landfills located on the State of Minas Gerais, Brazil. In order to fulfill the requirements of HDRUS-2D model in terms of the necessary parameters, the physical characteristics and typical configuration of the landfills, as well as the hydrogeological parameters of soils and aquifers related to the local of placement of the landfills, were taken in account for the formulation of the conceptual model.

    Evolution of microstructure and texture during heavy cold-rolling and annealing of Al-2.5%Mg-0.2%Sc alloy was investigated. For this purpose recrystallized sheets of 1mm thickness having finely dispersed precipitates were processed to 3 cycles of ARB (equivalent strain, εeq=2.4) followed by conventional rolling to a final thickness of 200μm resulting in total equivalent strain of 4.0. Evolution of ultrafine microstructure and strong copper or pure metal type texture were observed during deformation. During annealing very stable microstructure was observed up to 400°C but further annealing resulted in formation of a layered microstructure with deformed layer sandwiched between recrystallized layers. Formation of strong cube texture is not observed in the recrystallized layers. Isothermal annealing for longer time at 500°C leads to abnormal growth of Q orientation ({013}) within the deformed layer.

    The 1607-F3 waste site is the former location of the sanitary sewer system that supported the 182-F Pump Station, the 183-F Water Treatment Plant, and the 151-F Substation. The sanitary sewer system included a septic tank, drain field, and associated pipeline, all in use between 1944 and 1965. In accordance with this evaluation, the verification sampling results support a reclassification of this site to Interim Closed Out. The results of verification sampling demonstrated that residual contaminant concentrations do not preclude any future uses and allow for unrestricted use of shallow zone soils. The results also showed that residual contaminant concentrations are protective of groundwater and the Columbia River.

    At present, traditional fossil fuels are used predominantly in China, presenting the country with challenges that include sustainable energy supply, energy efficiency improvement, and reduction of greenhouse gas emissions. In 2007, China issued The Strategic Plan of the Mid-and-Long Term Development of Renewable Energy, which aims to increase the share of clean energy in the country's energy consumption to 15% by 2020 from only 7.5% in 2005. Biodiesel, an important renewable fuel with significant advantages over fossil diesel, has attracted great attention in the USA and European countries. However, biodiesel is still in its infancy in China, although its future is promising. This chapter reviews biodiesel production from conventional feedstocks in the country, including feedstock supply and state of the art technologies for the transesterification reaction through which biodiesel is made, particularly the enzymatic catalytic process developed by Chinese scientists. Finally, the constraints and perspectives for China's biodiesel development are highlighted.

    ABSTRACT We developed cergutuzumab amunaleukin (CEA-IL2v, RG7813), a novel monomeric CEA-targeted immunocytokine, that comprises a single IL-2 variant (IL2v) moiety with abolished CD25 binding, fused to the C-terminus of a high affinity, bivalent carcinoembryonic antigen (CEA)-specific antibody devoid of Fc-mediated effector functions. Its molecular design aims to (i) avoid preferential activation of regulatory T-cells vs. immune effector cells by removing CD25 binding; (ii) increase the therapeutic index of IL-2 therapy by (a) preferential retention at the tumor by having a lower dissociation rate from CEA-expressing cancer cells vs. IL-2R-expressing cells, (b) avoiding any FcγR-binding and Fc effector functions and (c) reduced binding to endothelial cells expressing CD25; and (iii) improve the pharmacokinetics, and thus convenience of administration, of IL-2. The crystal structure of the IL2v-IL-2Rβγ complex was determined and CEA-IL2v activity was assessed using human immune effector cells. Tumor targeting was investigated in tumor-bearing mice using 89Zr-labeled CEA-IL2v. Efficacy studies were performed in (a) syngeneic mouse models as monotherapy and combined with anti-PD-L1, and in (b) xenograft mouse models in combination with ADCC-mediating antibodies. CEA-IL2v binds to CEA with pM avidity but not to CD25, and consequently did not preferentially activate Tregs. In vivo, CEA-IL2v demonstrated superior pharmacokinetics and tumor targeting compared with a wild-type IL-2-based CEA immunocytokine (CEA-IL2wt). CEA-IL2v strongly expanded NK and CD8+ T cells, skewing the CD8+:CD4+ ratio toward CD8+ T cells both in the periphery and in the tumor, and mediated single agent efficacy in syngeneic MC38-CEA and PancO2-CEA models. Combination with trastuzumab, cetuximab and imgatuzumab, all of human IgG1 isotype, resulted in superior efficacy compared with the monotherapies alone.

    The non-conventional yeast Pichia ciferrii is known to secrete the sphingoid long-chain base phytosphingosine in a tetraacetylated form (TAPS). Sphingolipids are important ingredients in cosmetic applications as they play important roles in human skin. Our work aimed to improve TAPS production by genetic engineering of P. ciferrii. In the first step we improved precursor availability by blocking degradation of L-serine, which is condensed with palmitoyl-CoA by serine palmitoyltransferase in the first committed step of sphingolipid biosynthesis. Successive deletion of two genes, SHM1 and SHM2, encoding L-serine hydroxymethyltransferases, and of CHA1 encoding L-serine deaminase, resulted in a strain producing 65 mg((TAPS))g(-1)((cdw)), which is a threefold increase in comparison with the parental strain. Attempts to increase the metabolic flux into and through the L-serine biosynthesis pathway did not improve TAPS production. However, genetic engineering of the sphingolipid pathway further increased secretion of TAPS. Blocking of sphingoid long-chain base phosphorylation by deletion of the LCB kinase gene PcLCB4 resulted in a further increase in TAPS production by 78% and significant secretion of the direct precursor of phytosphingosine, sphinganin, in a triacetylated form (TriASa). Overproduction of two serine palmitoyltransferase subunits, Lcb1 and Lcb2, together with a deletion of the gene ORM12 encoding a putative negative regulator of sphingolipid synthesis resulted in a strain producing 178 mg((TAPS))g(-1)((cdw)). Additional overproduction of the C4-hydroxylase Syr2 converting sphinganine to phytosphingosine reduced TriASa production and further improved TAPS production. The final recombinant P. ciferrii strain produced up to 199 mg((TAPS))g(-1)((cdw)) with a maximal production rate of 8.42 mg×OD(600nm)(-1)h(-1) and a titer of about 2 g L(-1), and should be applicable for industrial TAPS production.

  6. Conventional mechanical ventilation

    Directory of Open Access Journals (Sweden)

    2010-01-01

    Full Text Available The provision of mechanical ventilation for the support of infants and children with respiratory failure or insufficiency is one of the most common techniques that are performed in the Pediatric Intensive Care Unit (PICU. Despite its widespread application in the PICUs of the 21st century, before the 1930s, respiratory failure was uniformly fatal due to the lack of equipment and techniques for airway management and ventilatory support. The operating rooms of the 1950s and 1960s provided the arena for the development of the manual skills and the refinement of the equipment needed for airway management, which subsequently led to the more widespread use of endotracheal intubation thereby ushering in the era of positive pressure ventilation. Although there seems to be an ever increasing complexity in the techniques of mechanical ventilation, its successful use in the PICU should be guided by the basic principles of gas exchange and the physiology of respiratory function. With an understanding of these key concepts and the use of basic concepts of mechanical ventilation, this technique can be successfully applied in both the PICU and the operating room. This article reviews the basic physiology of gas exchange, principles of pulmonary physiology, and the concepts of mechanical ventilation to provide an overview of the knowledge required for the provision of conventional mechanical ventilation in various clinical arenas.

The removed dumping earth found to have formaldehyde, benzenes, acetaldehyde, phenols, aromatic hydro carbons, polyaromatic compounds was a source of bad smelling substances that had entered the ambient air. A special study of the earth showed that it might yield volatile and bad smelling compounds, such as organic sulfides, aldehydes, mercaptans, ketones, etc. Their harmful health effects (during operations and in the late period) seem to be unlikely. When such work is under way, it is necessary to inform the population about possible consequences.

In agreement with the Italian legislative decree 81/08 we evaluated stress level of workers of three different sanitary structures located in the middle of Italy. 305 workers (physicians, nurses, technicians, auxiliary nurse, white collars) were submitted to a questionnaire designed by our team of work. The sector reporting higher stress level was represented by nurses, the sector with lower stress level was made of technicians. We proposed a set of measures aiming to reduce the load of stress based on the assumption that in this sector is fundamental to develop strategies of intervention both at organizational and individual level.

    Full Text Available The experiment was carried out in the years 2006-2008 in Bałcyny (N=53°35'49"; E=19°51'20". The aim of this study was to determine the effect of sulfur fertilization on the sanitary state of spring oilseed rape, winter oilseed rape, white mustard and Chinese mustard as well as on the species composition of fungi colonizing their seeds. Sulfur fertilization had a beneficial effect on the health of Brassicaceae plants infested by Alternaria blight, grey mould, Sclerotinia stem rot, Phoma stem canker and Verticillium wilt, but it had a varying effect on the occurrence of powdery mildew. Alternaria alternata and Penicillium spp. were isolated most frequently from Brassicaceae seeds. In general, more fungi (including pathogenic to Brassicaceae were isolated from the seeds of plants grown in non-sulfur fertilized plots. Pathogens occurred primarily on the seed surface, and their number decreased after surface disinfection of seeds.

    Environmental consequences from sanitary landfill as well as incineration with power generation were compared in terms of life cycle analysis (LCA) for Laohukeng Waste-disposal Plant that is under consideration in Shenzhen. A variety of differences will be resulted from the two technologies, from which the primary issue that affects the conclusion is if the compensatory phase in power generation can be properly considered in the boundary definition of LCA. Upon the compensatory phase is taken into account in the landfill system, the negative environmental consequences from the landfill will be more significant than those from the incineration with power generation, although the reversed results can be obtained as the compensatory phase is neglected. In addition, mitigation of environmental impacts through the pollutant treatment in the incineration process will be more effective than in the landfill process.

    Landfills are among the most common sources of pollution in ground water. Their widespread deployment, prolonged usage and the serious damage they cause to all of the elements of the environment are the reasons, which make the study of the problem particularly relevant. Most dangerous of all are the open dumps used until the middle of the twentieth century, from which large amounts of liquid emissions flowed freely (landfill infiltrate). In recent decades, the problem is solved by the construction of sanitary landfills in which they bury waste or solid residue from waste utilization plants. The bottom and the sides of the sanitary landfills are covered with a protective waterproof screen made of clay and polyethylene and the landfill infiltrate is led outside through a drainage system. This method of disposal severely limits any leakage of gas and liquid emissions into the environment and virtually eliminates the possibility of contamination. The main topic in the conducted hydrogeological study was a quantitative assessment of groundwater pollution and the environmental effects of re-landfilling of an old open dump into a new sanitary landfill, following the example of the municipal landfill of Asenovgrad, Bulgaria. The study includes: 1.A set of drilling, geophysical and hydrogeological field and laboratory studies on: -the definition and designation of the spatial limits of the main hydrogeological units; -identification of filtration parameters and migration characteristics of the main hydrogeological units; -clarifying the conditions for the sustentation and drainage of groundwater; -determininng the structure of the filtration field; -identifying and assessing the size and the extent of groundwater contamination from the old open dump . 2.Mathematical numeric models of migration and entry conditions of contaminants below the bottom of the landfill unit, with which the natural protection of the geological environment, the protective effect of the engineering

    weight are increased under both the controlled-release urea and conventional urea applications, while there are less effects on inflorescence diameters. Consequently, the yield increase is achieved mainly by increasing the inflorescence number per plant and 100-inforescence flesh weight. The yields treated by split fertilization of both controlled-release urea and conventional urea are higher than those treated by single basal application, and the highest yield is obtained in the application of controlled-release urea combined with conventional urea. Compared with conventional urea application treatments, the controlled-release urea application treat-ments lead to significant increases of total flavonoid content, chlorogenic acid content, soluble sugar content and protein content of C. morifolium, and those of the treatment applied controlled-release urea combined with conventional urea are higher than those others. Taking account of yield and quality, the split fertilization of controlled-release urea combined with conventional urea is the optimum under this experiment condition.

    Full Text Available This study aimed to verify the sanitary quality of tilapia (Oreochromis spp. sold in public markets in the city of Mossoro-RN. For such we made use of a checklist and an observational study to evaluate good handling practices in 10 establishments that commercialize fish. We obtained 30 samples of tilapia and evaluated them as to their sensory and microbiological aspects (Salmonella spp., coliforms at 45 ºC, Staphylococcus ssp. count, psychrotrophic bacteria and enterobacteria, as well as to their pH and internal and external temperature. We observed that none of the studied establishments were in accordance with the standards recommended by the legislation. Regarding the sensory evaluation, 83.3% of the samples showed compliance with the requirements of the legislation. As for the coliforms at 45 °C essay, the results ranged from 0.477 to 1.509 log10 CFU/g; in the Staphylococcus spp. essay we found results from 4.854 to 5.397 log10 CFU/g; and further, we found values from 3.884 to 4.937 and from 4.707 to 5.463 log10 CFU/g for enterobacteria and psychrotrophic bacteria, respectively. All the samples were within the requirements for contamination by Salmonella spp. (absence. The pH ranged from 5.99 to 6.18 and temperatures indicated non-compliance with the recommendations. Thus, we can infer that the sanitary quality of tilapia sold in public markets in Mossoro-RN was impaired, presenting a risk to consumer health due to unsatisfactory handling conditions.

    Because of fast-growing demand, export markets can absorb high value added products and offer high returns; for many developing countries export market development is thus a key requirement for rural income generation and rural growth. Although developing countries face increasingly strict sanitary and phytosanitary standards in their export markets, they can maintain and improve market access--and improve domestic food safety and agricultural productivity--by adopting a strategic approach to food safety, agricultural health and trade. High-income countries should increase development flows to help developing countries build the capacity to plan and execute the necessary strategies. The first proposal in this paper is to make two existing sets of guidelines widely available to interested parties, in particular through the World Bank and the World Organisation for Animal Health (OIE). The first covers the broad process of problem assessment, strategy development and action plan formulation; the second set deals with institutional analysis and training of staff of the official sanitary control services. The second proposal is that interested countries and donors should speed up the ongoing development of guidelines, computer software tools and training material to help countries quantify the importance and impact of food safety issues. The focus here is on a 'multipurpose agricultural data analysis and modelization system'. The third proposal is to carry out a case study to help demonstrate that a number of animal health issues related to food safety should be treated as relating to 'global public goods' and thus require intervention on a global scale. Possible candidates are foot and mouth disease and highly pathogenic avian influenza.

    Full Text Available Over the last decades, the emphasis on the health of dairy cows has changed from an individual to a herd level. In this scenario, the role played by the recording system and its interpretation by veterinarians has gained primordial importance. The records of productive and reproductive performance and of sanitary status from a southern Brazilian dairy cattle herd have been presented and discussed. The period of study was 2000-2009. Mean values per lactation period were 349D 8436M 290F 275P 201SCS (D: days in lactation, M: kg of milk yield, F: kg of fat, P: kg of protein and SCS: somatic cell score in 1000 cells/ml of milk. Major indexes of reproductive efficiency included age at first calving (31 months, services per conception (2.1, intercalving interval (428 days, calving to conception interval (146 days, mean annual rates of parturitions (76.2%, fetal losses (9.8-19.0%, and stillbirths (3.6%, apart of voluntary waiting period (94 days. Main information on sanitary status of the herd was associated with the mean prevalence of common disorders of dairy cattle such as anaplasmosis (29.8%, mastitis (27.8%, digital diseases (26.3%, ovarian cysts (21.3%, placental retention (19.7%, postpartum uterine infections (10.6%, and calf diarrhea (23.7% and pneumonia (16.8%, among others. In addition, culling reasons (low reproductive performance [56.3%] and udder/mastitis problems [33.6%], causes of cattle deaths (anaplasmosis [16.4%] and leukosis [11.4], and the impact of cattle diseases such as tuberculosis, leukosis, and neosporosis on the herd have also been presented and succinctly discussed.

    The U.S. Army Corps of Engineers and the Metropolitan Water Reclamation District of Greater Chicago regulate flows through control structures along the Lake Michigan lakefront and the Chicago Sanitary and Ship Canal (CSSC) for Lake Michigan diversion accounting, flood control, sanitary, and navigation purposes. This report documents the measurement and computation of flow through the Lockport Controlling Works (LCW) and the Lockport Powerhouse. This analysis aided in evaluation of the ratings at both structures, and the development of new ratings at the controlling works. The LCW structure consists of seven 30-feet (ft) wide sluice gates and is used to divert water from the CSSC and into the Des Plaines River. The flow regimes for the sluice gate included both free and submerged weir. Forty and 491 flow values from U.S. Geological Survey streamflow-gaging stations were used to develop equations describing free- and submerged-weir flow, respectively, through the sluice gates. The equations were developed for canal headwater elevations ranging from -7.0 to -10.5 ft Chicago City Datum (CCD), and tailwater (Des Plaines River at Lockport) to headwater (CSSC-LCW-Base) ratios ranging from 0.31 to 0.66. The Lockport Powerhouse structure consists of nine 9-ft wide by 14-ft high sluice gates and two 10-ft diameter turbines. Both tailwater and no-tailwater effect flow regimes occurred during nine measurements. Also, the canal headwater elevations ranged from -2.74 to -8.45 ft CCD, and the gates were configured six different ways during the measurements.

    Amongst all the different alternatives for the eliminator or treatment of MSW (Municipal Solid Waste), sanitary landfills is probably the one that is most widely employed to date, due to its economic advantages. With the coming into effect of the Spanish Containers and Packaging Law, alongside that of the Council Directive 1999/31/CE, concerning waste disposal, this situation will be substantially modified. At the same time, the application of said Directive will influence the amount of biogas generated in landfills. The present research work a study of the influence that the aforementioned Directive will have on the production of biogas in a sanitary landfill which currently disposes of around 400.000 Tm/year of MSW, 52% of which is easily biodegradable organic matter. The model proposed by Marticorena was applied and the kinetic parameters, MPO and d, were experimentally obtained by means of a pilot-plant study of MSW anaerobic degradation, the values employed being 173 Nm3 of biogas/Tm of the organic fraction of MSW for MPO, and 3 years for d. The results obtained in the model are compared with those obtained experimentally at the COGERSA landfill, Asturias, Spain. Twenty wells were chosen to analyse the production of biogas, giving an overall average yield of 70%. In 1999, around 4,100 m''3/h of biogas were extracted at the COGERSA landfill. Application of the model gave an estimation for 1999 of an average production of 5,369 m''3/h giving a maximum yield in the extraction of biogas of around 75%. The difference between the two average yields obtained may be due to the fact that the model only takes into account the easily biodegradable organic fraction, whilst in the landfill, given that more time has passed, other substances with a longer period of degradation, such as paper and cardboard, may also be degraded.

    The Quality Management System ISO 9001:2008 introduced by the Management Board of the hospital in the year 2007 resulted in change of the methods used by the Hospital Infection Control Team (HICT) to assess the sanitary-and-hygienic condition. The inspection protocol used by HICT was modified as part of the Quality Management System. It was supplemented by the score sheet which made the inspection results more objective. The purpose of the study was to assess the results of the supervision over the sanitary and epidemiologic condition of the hospital as well as personnel training carried out in the years 2007-2010 by the Hospital Infection Control Team (HICT) of Szpital Uniwersytecki nr 2 im. dr. J.Biziela (J.Biziel University Hospital no. 2). 407 inspection protocols issued in the years 2007-2010 were analysed. The sanitary/hygienic condition indicators and personnel education indicators were calculated based on the analysed data. The sanitary/hygienic condition indicator for the entire hospital in the years 2008-2010 amounted to over 91.50% and only in the year 2007 it was 89.33%. While the personnel education indicator for the entire hospital increased from 90.35% in 2007 to 93.75% in 2010. the assessment of hospital units performed on the basis of the new protocol of the sanitary/hygienic condition has been proven in practice, i.e. insufficient personnel education as regards hospital hygiene is efficiently detected by HICT at individual workstations and the Management Board of the hospital is notified on the ongoing basis on the results of supervision provided by HICT.

    To determine whether triple arterial phase acquisition via a combination of Contrast Enhanced Time Robust Angiography, keyhole, temporal viewsharing and parallel imaging can improve arterial phase acquisition with higher spatial resolution than single arterial phase gadoxetic-acid enhanced magnetic resonance imaging (MRI). Informed consent was waived for this retrospective study by our Institutional Review Board. In 752 consecutive patients who underwent gadoxetic acid-enhanced liver MRI, either single (n = 587) or triple (n = 165) arterial phases was obtained in a single breath-hold under MR fluoroscopy guidance. Arterial phase timing was assessed, and the degree of motion was rated on a four-point scale. The percentage of patients achieving the late arterial phase without significant motion was compared between the two methods using the χ{sup 2} test. The late arterial phase was captured at least once in 96.4% (159/165) of the triple arterial phase group and in 84.2% (494/587) of the single arterial phase group (p < 0.001). Significant motion artifacts (score ≤ 2) were observed in 13.3% (22/165), 1.2% (2/165), 4.8% (8/165) on 1st, 2nd, and 3rd scans of triple arterial phase acquisitions and 6.0% (35/587) of single phase acquisitions. Thus, the late arterial phase without significant motion artifacts was captured in 96.4% (159/165) of the triple arterial phase group and in 79.9% (469/587) of the single arterial phase group (p < 0.001). Triple arterial phase imaging may reliably provide adequate arterial phase imaging for gadoxetic acid-enhanced liver MRI.

    2016-03-01

    Spectral imaging systems need to be able to produce "conventional" images, and it's been shown that systems with energy discriminating detectors can achieve higher CNR than conventional systems by optimal weighting. Combining measured data in energy bins (EBs) and also combining basis material images have previously been proposed, but there are no studies systematically comparing the two methods. In this paper, we analytically evaluate the two methods for systems with ideal photon counting detectors using CNR and beam hardening (BH) artifact as metrics. For a 120-kVp polychromatic simulations of a water phantom with low contrast inserts, the difference of the optimal CNR between the two methods for the studied phantom is within 2%. For a polychromatic spectrum, beam-hardening artifacts are noticeable in EB weighted images (BH artifact of 3.8% for 8 EB and 6.9% for 2 EB), while weighted basis material images are free of such artifacts.

    Objective This research is to figure out whether the combination of Baoxinkang formula and conventional medicine therapy is better than conventional medicine therapy only in preservation of ATPase activity in chronic heart failure rat model. Methods Sprague-Dawley rats were randomly divided into 6 groups, the Baoxinkang group, conventional medicine therapy group, the Baoxinkang and conventional medicine therapy group, the trimetazidine and conventional medicine therapy group, control group and sham-operation group. Abdominal aortic constriction was performed to induce chronic heart failure . Baoxinkang(1020 mg·kg-1) in combination with conventional medicine therapy(Metoprolol 10 mg·kg-1, Captopril 5 mg·kg-1, Digoxin 0.0225 mg·kg-1) was administrated for 6 weeks. Echocardiography was performed to evaluate the cardiac function. The activity of Na+-K+-ATPase(NKA), Ca2+-Mg2+-ATPase(CMA) was examined by spectrometry. Results Echocardiography showed that either comparing with the control group or conventional medicine therapy group, Baoxinkang+conventional medicine therapy group had improved enlarged heart, higher ejection fraction, higher cardiac output and lower heart rate. Myocardial ATPase activity in Baoxinkang+conventional medicine therapy group were higher than those in the control group. Comparing with control group, Baoxinkang group has higher CMA activity, but similar NKA activity. No significant difference was observed in ATPase activity between Baoxinkang+conventional medicine therapy group and conventional medicine therapy group. Conclusion Baoxinkang formula could provide better protection to the activity of CMA, modulate the consumption of ATP to improve the cardiac function. The synergistic protection of Baoxinkang formula in combination with conventional medicine therapy may not completely cause by the preservation of ATPase activity. How does the Baoxinkang formula protect the activity of myocardial NKA and CMA needs further study.%目的:观察

    The 1607-F1 Sanitary Sewer System (124-F-1), consisted of a septic tank, drain field, and associated pipelines that received sanitary waste water from the 1701-F Gatehouse, 1709-F Fire Station, and the 1720-F Administrative Office via the 100-F-26:8 pipelines. The septic tank required remedial action based on confirmatory sampling. In accordance with this evaluation, the verification sampling results support a reclassification of this site to Interim Closed Out. The results of verification sampling show that residual contaminant concentrations do not preclude any future uses and allow for unrestricted use of shallow zone soils. The results also demonstrate that residual contaminant concentrations are protective of groundwater and the Columbia River.

    Full Text Available This paper describes the evaluation of the performance of an anaerobic-aerobic system, consisting of anaerobic filter (AF followed by biological aerated filter (BAF, operated with and without recirculation of treated effluent to mitigate the adverse effects of organic concentrations on nitrification and promote the removal of Total Nitrogen in anoxic ambient. In the first two steps, the application of the organic loading rate (OLR on BAF ranged from 0.49 ± 0.27 and 0.31 ± 0.08 kg BOD m-3 d-1 due to the reduction of surface application rate of 60 to 44 m3 m-2 d-1. In the third stage, with recirculation, OLR and surface application rate were 0.29 ± 0.02 kg BOD m-3 d-1 and 65.8 m3 m-2 d-1, allowing the system to reduce 43 ± 10% of average initial concentration of 72 mg L-1 Total Nitrogen. The application of organic loading rates in BAS, more than 0.30 kg BOD m-3 d-1 inhibited nitrification due to competition for oxygen

    Increased education of girls in developing contexts is associated with a number of important positive health, social, and economic outcomes for a community. The event of menarche tends to coincide with girls' transitions from primary to secondary education and may constitute a barrier for continued school attendance and performance. Following the MRC Framework for Complex Interventions, a pilot controlled study was conducted in Ghana to assess the role of sanitary pads in girls' education. A sample of 120 schoolgirls between the ages of 12 and 18 from four villages in Ghana participated in a non-randomized trial of sanitary pad provision with education. The trial had three levels of treatment: provision of pads with puberty education; puberty education alone; or control (no pads or education). The primary outcome was school attendance. After 3 months, providing pads with education significantly improved attendance among participants, (lambda 0.824, F = 3.760, peducation alone improved attendance to a similar level (M = 91.26, SD = 7.82) as sites where pads were provided with puberty education (Rural M = 89.74, SD = 9.34; Periurban M = 90.54, SD = 17.37), all of which were higher than control (M = 84.48, SD = 12.39). The total improvement through pads with education intervention after 5 months was a 9% increase in attendance. After 3 months, providing pads with education significantly improved attendance among participants. The changes in attendance at the end of the trial, after 5 months, were found to be significant by site over time. With puberty education alone resulting in a similar attendance level. This pilot study demonstrated promising results of a low-cost, rapid-return intervention for girls' education in a developing context. Given the considerable development needs of poorer countries and the potential of young women there, these results suggest that a large-scale cluster randomized trial is warranted. Pan African

    The 1607-F4 waste site is the former location of the sanitary sewer system that serviced the former 115-F Gas Recirculation Building. The system included a septic tank, drain field, and associated pipeline that were in use from 1944 to 1965. The 1607-F4 waste site received unknown amounts of sanitary sewage from the 115-F Gas Recirculation Building and may have potentially contained hazardous and radioactive contamination. In accordance with this evaluation, the verification sampling results support a reclassification of this site to Interim Closed Out. The results of verification sampling demonstrated that residual contaminant concentrations do not preclude any future uses and allow for unrestricted use of shallow zone soils. The results also showed that residual contaminant concentrations are protective of groundwater and the Columbia River.

    Last July the a new legal Rule concerning Sanitary Protection against Ionising Radiation was published, as a transposition of the EU Directive about the Basic Norms related to the sanitary protection of workers and population against the risks resultant of the ionising radiation. The origin of this legislation goes back to the revision of the protection doctrine by the International Commission of Radiation Protection (ICRP) en the year 1990. El scope of the revised Rule is the regulation of the protection of population and workers against ionising radiation, the establishment of the national protection system with its exposition and dose limits and the correspondent penalty regime. It also modifies the maximum radiation dose limits and reinforces the application of the optimisation principle in the use of ionising radiation. In this article, the novelties introduced by the new Rule are commented in detail, ordered by the Titles I to IX in which the Rule is divided. (Author)

    Full Text Available Abstract: This paper reviews and extends an understanding of a study on potential suitability of the natural soil in Endau Rompin National Park (PETA as a compacted soil liner for sanitary landfill. Since the demand for landfill system becomes obvious so that concerning construction and operation of landfills are increasing. A number of studies have been conducted for the liner system of landfill. Hence, study is required to choose the suitable type of material as liner barrier for the landfill system in term to achieve optimum long term performance. The sanitary landfill plays an important role in the framework of solid waste disposal. The compacted soil liner is a part of a liner structure for landfill to restrict leachate migration from facility into the environment. So that, if the landfill system is not well manage it will contaminate the soil and ground water, thus presenting a risk to human and environmental health. This study, natural soil will be taken from Endau Rompin National Park (PETA, Johor as soil sample for testing. Natural soil is an economy material as a liner system, and it does not decay easily from time to time. So it is an ideal material as a sanitary landfill liner system. In short, the purpose of this study is to compile and organize available information on the use of laboratory testing, as well as providing some guidance on the use of natural soil as barrier layer of landfill and also it suitability of physical and chemical properties natural soil as barrier layer of landfill. Based on the laboratory testing were conducted, found that soil sample taken form Endau Rompin National Park (PETA is suitable as compacted soil liner for sanitary landfill.

    Full Text Available Deaths by venomous animals are medical emergencies that can lead to death and thus constitute sanitary problems in some regions of the world. In the South of America, the accidents by these animals are a common sanitary problem especially in warm, tropical or subtropical regions, related with rural work in several countries. Argentina is located in the extreme South of South America and a minor part of the continental surface is in tropical or subtropical regions, where most of the accidents by venomous animals happen. However, in the big cities in the center and South of the country, with no relation to rural work, scorpionism, mostly due to the synanthropic and facultative parthenogenetic scorpion Tityus trivittatus, has become a sanitary problem in the last few decades. This scorpion is present in the biggest cities of Argentina and in the last decades has killed over 20 children in provinces of the center and north of the country, mostly in big cities. In addition, it seems that this species is growing and spreading in new regions of the cities. In this revision, some characteristics of this scorpion regarding its habitat, spreading in Buenos Aires city, combat measures and available treatments are discussed.

    Silicosis remains the most prevalent occupational disease worldwide. There have been no specific studies focusing on the association between exposure settings at work and the clinical severity in silicosis patients. In this study, we describe and compare the clinical characteristics and silicosis-associated exposure history at work among workers from several types of ceramic production facilities in Taiwan. We reviewed the medical records of 221 patients who were first diagnosed with silicosis at the Occupational Medicine Clinic of Northern Taiwan in 2012. For each patient, we collected data on demographic characteristics, smoking habits, working history, duration of exposure, and years on the first relevant job. We also retrieved clinical reports of the pulmonary function test and the baseline chest radiography used for silicosis staging. As compared to other ceramic workers, sanitary ceramic workers had a worse X-ray type (p=0.044), more advanced age (pceramic workers showed a comparable risk for worse X-ray findings to other ceramic workers (adjusted odds ratio=1.18, p=0.704). Results of multivariable regression models on individual lung function parameter also suggested comparably impaired lung function tests between sanitary and other ceramic workers (p>0.05). In this study, we found that sanitary ceramic workers were at a similar risk to other ceramic workers for moderate to severe silicosis when older age and longer working duration were accounted for.

    Full Text Available Energy forms the cornerstone of almost every economic, social and cultural sector in modern societies. Energy is regarded as an irreplaceable ingredient in such societies’ industrial development. The aim of this research was to estimate the generation of biogas in the city of Ensenada’s sanitary landfill to ascertain the amount of energy which could be generated from the solid waste being disposed of. Biogas estimates were conducted in two stages: a waste characterisation study followed by implementing the regulations proposed by SCS Engineers (SCS Engineers, 2009 regarding the Mexican biogas model (version 2.0. The results showed that a large quantity of organic matter (around 70% is a key element in anaerobic degradation of waste. As to energy generation, it is believed that a full 1.90 MW capacity will be reached in 2019. Such energy could increase Ensenada’s current electricity generation capacity by 3.46% and provide 60% of the energy needed for street lighting, thereby leading to USD $1.423 million in savings.

    This paper describes the trends in the recent fitness club facilities, their institutions as health improving facilities, and their facility management. The recent trend in opening new fitness clubs is characterized by noticeable decrease in new openings of small-scale clubs, and a single club is getting larger in size and fuller in menu line-up. The nationwide distribution of fitness clubs shows concentration in big cities like Tokyo and Osaka. Gymnastic devices, swimming pool, and athletic studios account for overwhelmingly highly in the kinds of facilities. Particularly, warm-water swimming pools have become indispensable, receiving high evaluation as an exercise safe and effective for middle to high aged people in terms of exercise physiology. Important considerations on joining a club are easiness in access, pleasant atmosphere, and high selectivity and cleanliness in facilities. Discontents include poor ventilation, and disagreeable temperature and humidity control. A medical expense deduction system for fitness club utilization based on physicians' prescriptions was inaugurated in 1992. Problems are in improving the quality of sanitary aspects, including air conditioning and air and water filtration in the facilities. 5 figs., 3 tabs.

    Full Text Available In 1999-2001 the effect of sowing method and plant density on the sanitary state of three cultivars of yellow lupine protected with fungicides against diseases was investigated. In spring of 2000 the seedlings on the experimental fields generally withered, which was most likely caused by the applied herbicide, however in 1999 and 2001 seedling black leg (complex of fungi was reported. The plants germinating from the seeds sown in points were clearly less attacked by pathogens evoking seedling black leg than those sown in rows. The most serious disease of yellow lupine was antracnose (Colletotrichum gloeosporioides. It occurred in all experimental years and its intensity increased during vegetation period. Cultivars of lupine used to the experiment were attacked by Colletotrichum gloeosporioides in a different degree, however, the injury index was mainly determined by weather conditions and the lupine development phase. The applied fungicides significantly limited the development of lupine antracnose. The effect of sowing method and varied plant density on disease intensity was varied.

    Full Text Available The preservation of seed quality during the storage period depends not only on the conditions during production and harvesting but also on the storage and maintenance of appropriate storage product conditions. Thus, the aim of this study was to evaluate the physiological and sanitary qualities of maize landrace seeds stored under two conditions. The maize seed batch varieties Oito carreiras, Cabo roxo and Lombo baio were used. Tests included germination, first count, cold test, accelerated aging and sanity. Based on the results it was concluded that the physiological quality of these seed varieties decreased with the storage period. The major fungi identified in the maize seeds during storage were from the genera Aspergillus, Fusarium and Penicillium, which caused deterioration and reduction of the physiological quality. Storage using a paper bag at a temperature of 10 °C did not prevent the deterioration of maize seeds but was more effective at preserving the quality of the seed compared with a plastic bag at room temperature.

    Analysis of national health insurance accounts in the Democratic Republic of Congo (DRC) clearly shows the importance of international sanitary aid, particularlyfor thefunding ofgeneral referral hospitals, the management of inpatients with AIDS, administration of health zones andfunding of preventive care providers. It The targeted changes described in this article could possibly optimize the efficiency ofinternational aidfor the DRC population, mainly for disorders considered to be a health care priority (i.e. malaria, AIDS, tuberculosis) as well as in the fight against malnutrition. Recommendations target the implementation of procedures for control offood chain security, changes in lifestyle and dietary habits of the population but also comprise extensive restructuring of the health care administration. A dramatic change of the structure in charge of drug distribution as well as eradication of the transfer of part of public health structure income to public health administrative personnel could result in the allocation of significantfunds to thefight against the most important diseases. Better collaboration between the various departments in charge of health care professional training, together with enhanced responsibility of health care personnel is essential. Independent and respected non-governmental organizations should be involved in an audit process, targeting all aspects of the current DRC health system. Eventually, in an equal opportunity perspective, taking into consideration the very high degree of poverty ofDRC inhabitants, implementation of health insurance programmes, use ofgeneric drugs and generalization ofmicro-credit initiatives should also be implemented.

    Full Text Available The monitoring of the water quality was done in the central valleys of Oaxaca state, finding very high concentrations of calcium, magnesium and carbonate in the waters from of deep wells that are located in the periphery of the river Atoyac, unlike the water that comes from the high parts of Etla valley, where there are maximum hardnesses of 140ppm, so for the distribution of both effluent to the city of Oaxaca and neighboring municipalities, suggesting a further dilution of the water treatment plant in "Fortin" in the city of Oaxaca, that after determining the Langelier index and other, with software found in the universal bibliography. The results indicate that water from the river Atoyac, have corrosive properties. In laboratory doing tests, the best dilution was 60 to 40% by volume, of water from Etla Valley and the periphery of the river respectively. Langelier index was converted to a negative, indicating saturation with respect to calcium carbonate (CaCO3 and will tend to dissolve, avoiding the deterioration of the sanitary units.

    Biological nitrogen removal via nitrite may represent a promising process for the optimization of nitrogen removal, in particular in the presence of a low biodegradable COD/TKN ratio. In the present study a lab-scale sequencing batch reactor (SBR) was monitored for approximately 2 years to evaluate the use of dissolved oxygen (DO), pH and oxidation-reduction potential (ORP) as monitoring parameters in order to optimize nitrogen removal via nitrite from leachate generated in old sanitary landfills. The SBR manifested a nitrification efficiency exceeding 99% whereas, due to the low biodegradability of the organic matter presents in the leachates, COD removal reached approximately 40% and the addition of external COD was required to accomplish denitrification process. Moreover, the results demonstrate that DO, pH and ORP are reliable parameters for use in the monitoring of nitritation and denitritation processes in SBRs treating landfill leachates. Through manual modification of the length of the SBR phases to achieve nitrogen removal via nitrite, the nitritation and denitritation processes were rendered unstable leading to the saving of 20% in addition of external COD, almost half the theoretically achievable value. Furthermore, the low dissolved oxygen concentration applied during the oxic phases in an attempt to increase the nitritation process would appear to cause the settling characteristics of the activated sludge to deteriorate.

    Full Text Available Palytoxin (PLTX, one the most potent marine toxins, and/or its analogs, have been identified in different marine organisms, such as Palythoa soft corals, Ostreopsis dinoflagellates, and Trichodesmium cyanobacteria. Although the main concern for human health is PLTXs entrance in the human food chain, there is growing evidence of adverse effects associated with inhalational, cutaneous, and/or ocular exposure to aquarium soft corals contaminated by PLTXs or aquaria waters. Indeed, the number of case reports describing human poisonings after handling these cnidarians is continuously increasing. In general, the signs and symptoms involve mainly the respiratory (rhinorrhea and coughing, skeletomuscular (myalgia, weakness, spasms, cardiovascular (electrocardiogram alterations, gastrointestinal (nausea, and nervous (paresthesia, ataxia, tremors systems or apparates. The widespread phenomenon, the entity of the signs and symptoms of poisoning and the lack of control in the trade of corals as aquaria decorative elements led to consider these poisonings an emerging sanitary problem. This review summarizes literature data on human poisonings due to, or ascribed to, PLTX-containing soft corals, focusing on the different PLTX congeners identified in these organisms and their toxic potential.

    The consumption of lacteal desserts in the province of Santa Cruz de Tenerife is notably high. However, there are no legal standards in Spain regarding microbiological quality. For this reason, we have decided that it would be of interest to carry out a health-sanitary study of these products, with the aim of discovering their microbial content. 330 samples of lacteal desserts on sale in the province of Santa Cruz de Tenerife have undergone analysis. They have been divided into three groups: cream caramel (egg and vanilla) (80), mousse (60) and the third group, known as "other desserts", which includes custard and the rest of lacteal desserts not included in the previous groupings (190). Neither E. coli, Salmonella spp., Shigella spp., nor Staphylococcus aureus have been detected in any of the samples analysed. In spite of the fact that the results obtained do not reflect high microbiological contamination, we consider it necessary to lay down legal standards, with reference values, for these lacteal products, which will guarantee good microbiological quality.

    Full Text Available ABSTRACT The purpose of this study was to evaluate the effect of the chemical treatment with fungicide, insecticide, micronutrient and polymer on physiological and sanitary quality of soybean seeds during storage. The treatments were arranged in a 3 x 5 x 5 factorial scheme (cultivars x seeds treatment x storage period, in completely randomized design with four replicates. Three cultivars were used: NA 4823RG, BMX TurboRR and Fundacep 62RR. The treatments were: T1: no chemical treatment, T2: fungicide, insecticide and micronutrient; T3: fungicide, insecticide, micronutrient and polymer, T4: fungicide; T5: insecticide. After the chemical treatment, the seeds were stored under environmental conditions from May to December 2012, and seed quality was evaluated at 0, 2, 4, 6 and 8 months of storage. Seeds water content and physiological quality were determined through tests of germination, accelerated aging, seedling length, seedling dry weight and sanity. The treatment with fungicides, insecticides, micronutrients and polymer did not affect seed quality over eight months of storage and promoted the control fungi associated with the seeds.

    There are many ways to eliminate the municipal solid wastes, but only a few help to treat them and to dispose of them suitably. Some of the forms to avoid the problems that the trash originate are: not to produce it, recycling it in a 100% or creating a fictitious market where its value is equal to or greater than the product that gave origin to it; in any case, these alternatives are not absolutely practical. The trash can be incinerated, be segregated, be recycled partially or also be arranged in sanitary landfills. Anyway, the trash has always existed and it will continue existing for sure.

    Correlation of unpleasantness and electroencephalography (EEG)-based responses induced by persistent mechanical/dry stimulation and acute wet stimulation via wearing sanitary napkins (SN) was investigated in the present study. Mesh and nonwoven SN were employed, and the effects were studied during the follicular and menstrual phases. The mesh SN characteristically displayed a higher textural surface-roughness. The results in the follicular phase revealed no change in EEG responses to nonwoven SN-induced persistent mechanical stimulation, while the same dry stimulus induced significant increases in alpha2 and beta activities in the bilateral frontal areas accompanied by markedly exacerbated unpleasantness with mesh compared with nonwoven SN. The present result with SN application confirms the previous finding that unpleasantness is well correlated with EEG responses of bilateral frontal areas. Interestingly, although the alpha2 activities were enhanced more with mesh than nonwoven SN during the menstrual phase, unpleasantness between the two textural materials was not different. Moreover, it is suggested that acute unpleasantness induced by wet stimulation is related with elevated EEG responses in the left hemisphere. These data suggest that subjective evaluation of effects of physical stimulation on the human body may not be adequately reliable, and objective assessment of physiological activities with EEG is warranted.

    The purpose of the study was to investigate the potential for stabilization of sanitary landfills by injecting fly ash. The method is supposed to prevent differential settlements in landfills and by that to counteract damages in the final cover. Injecting fly ash may also affect the chemical development in a positive way and prevent metal leaching. Pilot experiments at the Tveta waste recycling center (Tveta Aatervinningsanlaeggning) have been performed in order to estimate if the grouting technology is a suitable method for sanitary landfills. Fly ashes from the combustion of bio fuels were used in these tests. A literature study and laboratory experiments in order to prepare the field experiments were also part of the project. About 100 tons of ash slurry were injected during the pilot experiments. This corresponds to a filling degree of approximately 12-16 % of the available pores in the landfill body. As a result of the pilot test, the following conclusions can be drawn: Ash can be mixed with water to a pumpable slurry which can be injected without hardening inside the equipment. Neither the waste nor the grouting material caused a backpressure during the injection and nothing indicates that the injected ash deforms the landfilled waste. The ash-water-slurry flows through the voids in the waste easily. Thus, the ash may dispread quite far from the injection holes. Using a more powerful equipment backpressure and movements in the waste might occur. It was not possible to estimate the flow required for backpressure in this study. Large variations are possible but for safety reasons the maximal pressure should be limited with regard to the expected stability in the actual area. The grouted ash will harden within the landfill body within a couple of days. It accumulates in hard but brittle lumps, which may result in an increased stability of the landfill. Further studies are necessary in order to evaluate how the stability is affected and what amounts of ash are

    Full Text Available This study examined the possibility of reusing the ceramic wastes of sanitary ware as coarse aggregate, in partial substitution (15, 20 y 25 % of natural coarse aggregates. Firstly, the characterization of recycled coarse ceramic aggregate was carried out subsequently proceeded to establish the parameters of dosage and manufacture of different concretes. Lastly, tests were conducted using these mixes to characterize physical and mechanical, and a study was carried out to identify the crystalline phases. Results showed that as the substitution proportion increased, the mechanical properties of the concrete improved, whilst physical properties remained practically constant. In view of these results, we conclude that it is possible to use this type of ceramic waste as coarse aggregate when mixing concrete destined for structural purposes.

    Full Text Available The results of the comparative assessment of the sanitary and epidemiological quality of the ambient air in Moscow and the Russian Federation, that demonstrate a decrease of the air pollution level in 2014 in comparison with 2012, both in Moscow and in the Russian Federation, are presented in this study. It has been noted that most of the excess of hygienic air quality standards in the areas of Russian cities are recorded on stationary observation stations situated close to the motorway, located in residential areas, and in Moscow – in the zones of industrial enterprises’ impact. It has been revealed that the tendency to the reduction of the negative impact from industrial enterprises on air pollution is registered in the whole of the Russian Federation and in Moscow. It is demonstrated that the high-priority contaminating agents, the content of which for the year 2014 in the Russian Federation exceeded the hygienic daily average standards in 5 and more times, are mainly: benzo (a pyrene, suspended substances, sulfur dioxide, benzene, formaldehyde, nitrogen dioxide, hydrogen sulfide, etc. To assess the quality of the ambient air in Moscow, the method of "inverse distance" and inter- and extrapolation of the data obtained from the observation stations on the whole territory of Moscow has been used. The study shows that the air quality of the individual administrative districts of Moscow varies considerably, and is determined by the traffic load level as well as by the volume of emissions of the industrial enterprises and the wind rose. As high-priority contaminating agents affecting the air quality, nitrogen dioxide, ammonia, benzene, suspended substances, ozone and formaldehyde are distinguished. It is noted that close to the highway near Moscow there is an excessive concentration of nitrogen dioxide, formaldehyde, phenol, and carbon monoxide, and in areas close to industrial zones – nitrogen dioxide, phenol formaldehyde and benzo (a

    Full Text Available Introduction. Shopping habits have changed over the past several years and consumers choose shopping centres, where they can spend time and visit restaurants. People usually wash hands before meals, but toilets in shopping centres are visited by hundreds of users every day which makes their cleanliness questionable. Therefore, the aim of this study was to assess the sanitary condition of electrical hand dryers in toilets of the selected shopping centres in Kraków. Material and methods. Air was sampled at the outlet of electrical hand dryers and surface swabs of hand dryers were taken in toilets of five shopping centres. Air sampling was conducted using the MAS-100 impactor. The number of mesophilic bacteria, fungi, actinomycetes, staphylococci and Escherichia coli was determined. The results of air analyses were compared with the limits provided by the Polish Standards on air quality. Results. The number of microorganisms varied between the studied centres. In terms of mesophilic bacteria and fungi the air was unpolluted. The concentration of actinomycetes however significantly exceeded the limits set by the Polish Standards. Numerous Escherichia coli were found both in the air and in swabs in one of the centres. However the number of E. coli and staphylococci did not exceed the minimum infective dose. Conclusions. The studies showed high concentrations of airborne actinomycetes and staphylococci. Also the presence of E. coli in the air and swabs allows the conclusion that legal regulations for concentrations of airborne microorganisms are necessary to make people aware of this problem. However, it was found that using electrical hand dryers does not have impact on human health.

    This study was designed to provide a diagnostic, symptomatologic and sanitary assessment of schizophrenic patients in the network of institutions of the Plate-Forme Psychiatrique Liégeoise (Liège, Belgium). The diagnosis of schizophrenia was based on the DSM IV. Demographic, social and global functioning (GAF scale) data were collected from the Résumé Psychiatrique Minimum (RPM) , a clinical summary which has been imposed for each psychiatric hospital stay by the Belgian Ministry of Public Health. Symptoms components were derived from the Psychosis Evaluation tool for Commom Use by Caregivers (PECC). In the 44 participating institutions, 793 cases of schizophrenia were reported (533 men and 260 women) with a mean age of 46.1 14.4 years. The study confirmed the predominance of men in schizophrenia (67%) but revealed that women were about 6 years higher than men. PECC symptoms were studied in a random sample of 184 patients extracted from the 793 initial patients and analysed with respect to age, sex and type of care (full-time or part-time hospitalization, ambulatory care). Negative, cognitive and total PECC scores did not vary with sex but were positively correlated with age. Hospitalized patients were significantly older than the others. The cognitive deficit was significantly higher in hospitalized patients than in other patients, while the perception of the disease tended to be more apparent in ambulatory than in hospitalized patients. Data were also related to social information and global functioning. The GAF scores increased with age but were comparable in men and women. Moreover, GAF scores were significantly lower in catatonic type schizophrenia patients than in others.

    Full Text Available Internationalization consists of extending an organization's operations abroad. It involves decisions based on objective criteria and on an evaluation of strategies for entering the foreign market. The problem addressed in this study concerns a Brazilian firm’s difficulties developing its operations abroad. Thus, the purpose of this study was to identify the internationalization process of an industry in the sanitary ware segment in the development of its operations in another country. The research method employed was the single case study and data was collected by means of a semi-structured research script applied to company executives. The results showed that the internationalization process is characterized by the dynamic learning model (Uppsala Model, according to which an organization develops its activities abroad gradually, as it acquires experience and expertise in the market. The company is attempting to overcome cultural barriers and psychic distance in a slow internationalization process, aligned with the differentiation strategy and focus that it uses in the Brazilian market. This strategy comprises a sequence of planned and deliberate steps, with low investment exposure and risk. It was found that the firm adopts a strategy of exporting through distributors, this being a critical success factor, but that the distributor approval and development process lacks robust and formalized structuring. There are opportunities for improvement in the process of competitive intelligence in order to systematize the search and interpretation of information about the markets in which the company wants to operate.  Key-words: Internationalization of companies. Uppsala Model. Strategy. Competitive intelligence.

    The onset of menstruation is one of the most important physiological changes occurring among girls during the adolescent years. Menstruation heralds the onset of physiological maturity in girls. It becomes the part and parcel of their lives until menopause. Apart from personal importance, this phenomenon also has social significance. In India, menstruation is surrounded by myths and misconceptions with a long list of "do's" and "don'ts" for women. Hygiene-related practices of women during menstruation are of considerable importance, as it may increase vulnerability to Reproductive Tract Infections (RTI's). Poor menstrual hygiene is one of the major reasons for the high prevalence of RTIs in the country and contributes significantly to female morbidity. Most of the adolescent girls in villages use rags and old clothes during menstruation, increasing susceptibility to RTI's. Adolescents constitute one-fifths of India's population and yet their sexual health needs remain largely unaddressed in the national welfare programs. Poor menstrual hygiene in developing countries has been an insufficiently acknowledged problem. In June 2010, the Government of India proposed a new scheme towards menstrual hygiene by a provision of subsidized sanitary napkins to rural adolescent girls. But there are various other issues like awareness, availability and quality of napkins, regular supply, privacy, water supply, disposal of napkins, reproductive health education and family support which needs simultaneous attention for promotion of menstrual hygiene. The current article looks at the issue of menstrual hygiene not only from the health point of view, but also considers social and human rights values attached to it.

    Full Text Available Floating point multiplication is a critical part in high dynamic range and computational intensive digital signal processing applications which require high precision and low power. This paper presents the design of an IEEE 754 single precision floating point multiplier using asynchronous NULL convention logic paradigm. Rounding has not been implemented to suit high precision applications. The novelty of the research is that it is the first ever NULL convention logic multiplier, designed to perform floating point multiplication. The proposed multiplier offers substantial decrease in power consumption when compared with its synchronous version. Performance attributes of the NULL convention logic floating point multiplier, obtained from Xilinx simulation and Cadence, are compared with its equivalent synchronous implementation.

    Full Text Available Cheese type cabacinha from Vale do Jequitinhonha is obtained by curd heating in a similar process made to Mozzarella, but the raw milk is unpasteurized and the final product is stored unpackaged and at room temperature. This milk derivative may contribute to the increase the income of the local population, especially the residents of the edges of roads, due to the flow of vehicles and possible buyers. The purpose of this work was to identify the physical and sanitary conditions of cheese type cabacinha market places present in three municipalities of the Vale do Jequitinhonha, MG, Brazil. Previously the investigation was detected the number of marketplaces that sell these cheese in the Medina, Cachoeira de Pajeú and Pedra Azul, municipalities of the state of Minas Gerais, Brazil, located on the surrounding area of the highways BR 251 and BR 116. Afterward as developed a physical and sanitary checklist and it were filled in loco. It was observed that most market places were not provided of masonry walls, piped water or toilet and sink. It is also common to the presence of possible contamination vectors in surroundings, such as dogs and insects. It is verified that most of these cheese is exposed in pairs held by string and unpackaged. This study demonstrated the precariousness of the physical structures and consequently the lack of adequate sanitary conditions in the cheese type cabacinha market places. Because it is an artisanal product from family farming, which generates income and employment in the field deserve more attention of competent state and municipal authorities.

    The present study was conducted to evaluate the bacteriological and sanitary quality of drinking water produced in Makkah Al-Mokarama during the high season in the month of Ramadan. Water samples were collected both from the drinking water stations and the water tankers (in Arabic language called whitats) used to transport and distribute water in different places in the Holy city. Water samples were analyzed to determine the densities of HPC at 22 and 37 degrees C, total coliforms, E. coli and S. aureus. The bacteriological analysis of drinking water samples at 37 degrees C proved that 6.7-33.3, 20-46.7, 0-20 and 0-6.7% of total water samples contained HPC, total coliforms, E. coli and S. aureus, respectively which were higher than the safe limits for drinking water. The bacterial analysis of drinking water varied from one water station to another. On the other hand, drinking water transported by tankers appeared to be in the lowest category of water quality. Because out of total water samples 40-59%, 60-68.8%, 31.2-37.5%, 10-25% contained HPC, total coliforms, E. coli and S. aureus, respectively, which were higher than the established safe limits of drinking water. One possible reason for poor quality of drinking water could be attributed to the application of inadequate water disinfection treatments and also the absence of sanitary aspects as supported by the bacteriological analysis which holds true especially for water supplied by tankers. In conclusion, it is important to apply proper water disinfection measures and provide sanitary monitoring programs during the production of drinking water as a whole and for the water tanker in particular.

    The aim of this work was to study the yeast populations and the main hygienic-sanitary microbial indicators in water buffalo mozzarella produced and commercialized in Minas Gerais, Brazil. Forty-two water buffalo mozzarella samples were purchased from retail outlets in Belo Horizonte. In addition, five samples of consecutive starter cultures, curd before acidification, acidified curd and mozzarella were collected at an industry in the city of Oliveira. Only three of the five water samples analyzed were suitable for consumption according to Brazilian sanitary standards. Four milk samples were highly contaminated with fecal coliforms, and did not meet the minimal hygienic-sanitary standards according to Brazilian regulations. Only one sample of buffalo muzzarela purchased from retail outlets exceeded the limit for coagulase-positive Staphylococcus. Eleven samples showed counts of thermotolerant coliforms higher than 5 × 103 CFU.g−1, but still lower than the maximum permitted by the Brazilian laws. Salmonella spp. and Listeria monocytogenes were not isolated. Debaryomyces hansenii, Candida lusitaniae and C. parapsilosis were the prevalent yeast species isolated from cheese. Among samples from the production stages, the acidified curd presented the highest numbers of yeasts, with C. catenulata being the most frequent species isolated. Some opportunistic yeast species such as C. guilliermondii, C. tropicalis, C. parapsilosis, C. lusitaniae, C. catenulata, C. rugosa and C. krusei occurred in the mozzarella cheese samples analyzed. The mozzarella cheese presented a low microbial load as compared to other cheese already studied, and the yeast biota included species typical of cheese and also opportunistic pathogens.

    Metodi: lo studio è stato effettuato mediante l’invio postale di un questionario di 39 domande a risposta multipla ad un campione random di medici della provincia di Roma e della Calabria. I dati si riferiscono ai primi 211 questionari pervenuti.

    Risultati: il livello delle conoscenze appare elevato, in quanto la maggior parte dei medici intervistati riconosce l’utilità dei trials clinici nella valutazione di efficacia degli interventi sanitari (81.6% e sa che la meta-analisi è una metodica che consente di sintetizzare i risultati di diversi studi individuali (72.0%; le conoscenze, tuttavia, si abbassano in occasione di quesiti più tecnici, quali quelli relativi, ad esempio, alle misure di associazione. Più articolate sembrano essere le attitudini nei confronti della meta-analisi, in quanto, sebbene il 76.9% ritenga che solo gli interventi sanitari di provata efficacia debbano essere offerti gratuitamente ai cittadini (76.9%, molti medici, tuttavia, reputano che molte decisioni cliniche debbano basarsi soprattutto sulle esigenze del singolo paziente (61.3%. Sebbene molti medici leggano con regolarità trials clinici (76.1% e con minore frequenza meta-analisi (52.7%, decisamente elevate appaiono le percentuali di coloro che non hanno mai utilizzato nella loro attività professionale i risultati di trials clinici (38.7% e di meta-analisi (56.2%. Quasi la metà del campione esaminato giudica insufficiente il livello di conoscenze in materia (47.3%, e la quasi totalità ritiene importante migliorare le proprie conoscenze metodologiche (92.0%.

    Full Text Available The study examines the role of work life balance, career development and supervisor support on organization commitment over employees of unattended, ceramic sanitary ware factories in India. It also verifies the influence of organization commitment on retention and its mediating role. Findings reveal that organization commitment influences retention and all the above factors enhance it. Moreover, organization commitment partially mediates the relationship between proposed factors and retention. It also found that organization’s career development provision alone is not enough and need to be modified according to the employer’s expectation. Managerial implications and suggestions for future research were discussed.

    Background Health concerns unique to women are growing with the large number of women venturing into different trades that expose them to hot working environments and inadequate sanitation facilities, common in many Indian workplaces. Objective The study was carried out to investigate the health implications of exposures to hot work environments and inadequate sanitation facilities at their workplaces for women workers. Design A cross-sectional study was conducted with 312 women workers in three occupational sectors in 2014–2015. Quantitative data on heat exposures and physiological heat strain indicators such as core body temperature (CBT), sweat rate (SwR), and urine specific gravity (USG) were collected. A structured questionnaire captured workers perceptions about health impacts of heat stress and inadequate sanitary facilities at the workplace. Results Workplace heat exposures exceeded the threshold limit value for safe manual work for 71% women (Avg. wet bulb globe temperature=30°C±2.3°C) during the study period. Eighty-seven percent of the 200 women who had inadequate/no toilets at their workplaces reported experiencing genitourinary problems periodically. Above normal CBT, SwR, and USG in about 10% women workers indicated heat strain and moderate dehydration that corroborated well with their perceptions. Observed significant associations between high-heat exposures and SwR (t=−2.3879, p=0.0192), inadequate toilet facilities and self-reported adverse heat-related health symptoms (χ2=4.03, p=0.0444), and prevalence of genitourinary issues (χ2=42.92, p=0.0005×10−7) reemphasize that heat is a risk and lack of sanitation facilities is a major health concern for women workers.

    Full Text Available Background: Health concerns unique to women are growing with the large number of women venturing into different trades that expose them to hot working environments and inadequate sanitation facilities, common in many Indian workplaces. Objective: The study was carried out to investigate the health implications of exposures to hot work environments and inadequate sanitation facilities at their workplaces for women workers. Design: A cross-sectional study was conducted with 312 women workers in three occupational sectors in 2014–2015. Quantitative data on heat exposures and physiological heat strain indicators such as core body temperature (CBT, sweat rate (SwR, and urine specific gravity (USG were collected. A structured questionnaire captured workers perceptions about health impacts of heat stress and inadequate sanitary facilities at the workplace. Results: Workplace heat exposures exceeded the threshold limit value for safe manual work for 71% women (Avg. wet bulb globe temperature=30°C±2.3°C during the study period.

    Obiettivo: misurare la quota di differenza sociale nella salute generata dall’accesso al sistema di cure, attraverso un follow-up dei pazienti ricoverati presso il principale ospedale di Torino.

    Metodi: tutti i primi ricoveri per infarto del miocardio (patologia acuta - AD e per tumori del coloretto (patologia cronica - CD dal 2000 al 2001 erano arruolabili. A questi è stato proposto un questionario sulle modalità di accesso ai servizi sanitari. È stata inoltre analizzata la cartella clinica per la valutazione degli interventi intra-ospedalieri. Indicatore di categoria sociale: titolo di studio.

    Risultati: analizzati 268 pazienti. Il 99% con AD ed il 97.5% di quelli con CD hanno aderito. Arruolati maggiormente uomini pensionati (circa 67%, condizione dovuta al tipo di patologia in studio. Sintomatologia di esordio: tipica della patologia infartuale e del colon-retto. Per questa ultima la lievità, quando unico sintomo, risulta elemento fuorviante. I pazienti con AD si sono rivolti direttamente all’ospedale (87.4%; i pazienti con CD hanno scelto il medico di famiglia (MMG per l’iter diagnostico, una piccola percentuale lo specialista privato (8.6%.

    Il numero di medici consultati in caso di CD è mediamente

    Il ritardo diagnostico risulta per la CD nettamente
    più elevato nelle prime tappe della storia dell’accesso
    per le categorie sociali più svantaggiate, con brevissimo
    tempo fra la diagnosi e il ricovero.

    Conclusioni: per le categorie sociali più basse in caso di CD, il tempo fra primo sintomo e contatto con il medico è più lungo (minore sensibilità ai primi segni e sintomi di malattia rispetto agli strati sociali più alti; cosicché il paziente giunge al ricovero con prognosi peggiore; tuttavia, a questo ritardo si contrappone una

    The current study has proved the technical feasibility of including electrochemical advanced oxidation processes (EAOPs) in a multistage strategy for the remediation of a sanitary landfill leachate that embraced: (i) first biological treatment to remove the biodegradable organic fraction, oxidize ammonium and reduce alkalinity, (ii) coagulation of the bio-treated leachate to precipitate humic acids and particles, followed by separation of the clarified effluent, and (iii) oxidation of the resulting effluent by an EAOP to degrade the recalcitrant organic matter and increase its biodegradability so that a second biological process for removal of biodegradable organics and nitrogen content could be applied. The influence of current density on an UVA photoelectro-Fenton (PEF) process was firstly assessed. The oxidation ability of various EAOPs such as electro-Fenton (EF) with two distinct initial total dissolved iron concentrations ([TDI]0), PEF and solar PEF (SPEF) was further evaluated and these processes were compared with their analogous chemical ones. A detailed assessment of the two first treatment stages was made and the biodegradability enhancement during the SPEF process was determined by a Zahn-Wellens test to define the ideal organics oxidation state to stop the EAOP and apply the second biological treatment. The best current density was 200 mA cm(-2) for a PEF process using a BDD anode, [TDI]0 of 60 mg L(-1), pH 2.8 and 20 °C. The relative oxidation ability of EAOPs increased in the order EF with 12 mg [TDI]0 L(-1) < EF with 60 mg [TDI]0 L(-1) < PEF with 60 mg [TDI]0 L(-1) ≤ SPEF with 60 mg [TDI]0 L(-1), using the abovementioned conditions. While EF process was much superior to the Fenton one, the superiority of PEF over photo-Fenton was less evident and SPEF attained similar degradation to solar photo-Fenton.

    The influences of selected factors on the generation and recovery of methane gas from sanitary landfills were investigated. The factors included encapsulation, shredding, air classifying, moisture, and pH. Facilities consisting of six model sanitary landfill cells, each with a capacity of approximately 450 cubic yards of municipal waste, and auxiliary subsystems were constructed. Municipal waste in each cell is contained in a 30-mil thick polyvinly chloride plastic sheeting forming a virtually gas-tight envelope. Two cells were filled with as-collected urban waste, two with shredded waste, and two with shredded and air classified waste, constituting three pairs of cells. One of each pair is a control cell with the other used as an experimental variable. Systems were provided for adding measured amounts of water, removing and recirculating leachate, and for extracting gas and measuring gas flow. During testing, gas production and internal cell characteristics were measured to determine the effects of mechanical processing, moisture content, and leachate pH.

    GIS is a powerful tool that may help to better manage natural resources. In this paper, we present a GIS model developed for the state of Morelos as an aid to determine whether a potential site, Loma de Mejia, met the Mexican Federal Guidelines. The Mexican Government has established federal guidelines for sanitary landfill site selection (NOM-083-SERMARNAT-2003). These guidelines were translated into a water-based Geographic Information System and applied to the state of Morelos, Mexico. For these examples, we used the SIGAM® (Sistema de Información Geográfico del Agua en México; a water-based GIS for Mexico) which has at least 60 layers from the National Water Commission (CONAGUA), the national mapping agency (INEGI; Instituto Nacional de Estadística, Geografía e Informática), NASA, and academic institutions. Results show that a GIS is a powerful tool that may allow federal, state and municipal policy makers to conduct an initial regional site reconnaissance rapidly. Once potential sites are selected, further characterization must be carried out in order to determine if proposed locations are suitable or not for a sanitary landfill. Based on the SIGAM© software, the Loma de Mejia would not comply with the Mexican Federal Guidelines.

    This study analyses law bills towards the sanitary control of alcohol advertisement in the mass media presented to the Brazilian Congress from 1988 to 2004. The sanitary control of this advertising is a controversial issue bringing about an ethical-political debate in which the health-protecting interests conflict with commercial ones even after scientific evidence has established increasing alcohol intake as a health and social issue worldwide. The content analysis of 67 of such law bills was carried out, and these proposals were shown to consist mostly of strategies to both cope with alcohol advertising by dissociating from the product those values that might interfere with the children and teenagers' building of their social identity and limit advertisement contents in the mass media given the higher vulnerability of the subjects in that age range. This study reveals complexes challenges for the control of alcohol advertisement that in turn lead to rethinking the action of the State apparatus in dealing with this major public health issue.

    This study evaluated the breath CH4 excretion and concentration of M. smithii in intestinal microbiota of schoolchildren from 2 slums. One hundred and eleven children from a slum near a sanitary landfill, 35 children of a slum located away from the sanitary landfill, and 32 children from a high socioeconomic level school were included in the study. Real-time PCR was performed to quantify the M. smithii nifH gene and it was present in the microbiota of all the participating children, with higher (P landfill (3.16 × 10(7) CFU/g of feces), comparing with the children from the slum away from the landfill (2.05 × 10(6) CFU/g of feces) and those from the high socioeconomic level group (3.93 × 10(5) CFU/g of feces). The prevalence of children who present breath methane was 53% in the slum near the landfill, 31% in the slum further away from the landfill and, 22% in the high socioeconomic level group. To live near a landfill is associated with higher concentrations of M. smithii in intestinal microbiota, comparing with those who live away from the landfill, regardless of their socioeconomics conditions.

    The objective of this study was to evaluate the presence of hygienic and sanitary indicator microorganisms in samples of food served in public schools in Porto Alegre. All the food served in the meal of the session visited was analyzed for Escherichia coli, coagulase-positive Staphylococcus, Salmonella sp. and Shigella sp. Of the total of 196 food products analyzed in 120 schools, 4 contained and Escherichia coli score above the permitted level, and 2 contained coagulase-positive Staphylococcus. Neither Shigella nor Salmonella genus were detected. In the majority of schools studied, it was found that food was of an adequate hygienic-sanitary standard. However, only municipal schools had the supervision of a technician responsible for school food. In the state schools, 60% had never been visited by a nutritionist and in these schools several procedures failed to comply with legal requirements. In most of the schools studied, the food served to students was within adequate standards, though the problems detected revealed the need for the implementation of Best Practices in the school environment.

    Management of ankylosing spondylitis (AS) is challenged by the progressive nature of the disease. To date, no intervention is available that alters the underlying mechanism of inflammation in AS. Currently available conventional treatments are palliative at best, and often fail to control symptoms in the long term. Current drug treatment may perhaps induce a spurious state of "disease remission," which is merely a low level of disease activity. Non-steroidal anti-inflammatory drugs are first ...

    Full Text Available A great number of the conventions referring to nature, even if they do not refer ton particular species, were limited from the point of view of geography and territories: we may give as example here a convention for the protection of flora, fauna and panoramic beauties of America, the African convention for nature and natural resources… By the Stockholm conferences, from the 5th of June 1972, we entered in a “dynamic of globalization”. Article 1 of the Declaration that followed the conference is important for the global awareness: “Human beings have the basic right for freedom, equality and conditions of a satisfying life, in an environment with a quality that allows him to live with dignity and well being. He has the solemn duty to protect and improve the environment for the present and future generations (…”. This article proclaims a right for the environment. A new law seems to have arisen with the apparition of this convention: the right of a healthy human being and of a healthy environment. This law is bipolar because it associates the human beings to nature. Human beings have the right to live in a healthy environment and this is why he has to protect nature. This does not represent a right of the human beings from a strict point of view. This is a right that has a universal value. The right to a healthy environment can not be put in the same category as the right to live or the right to be healthy, because this right contains the latter.

    Tritium content in the leachate of sanitary landfills, in concentrations well above those observed in global precipitation, can be used as a tracer for the evaluation of the contamination of groundwater in piezometers of the landfills and in neighbouring tubular wells. This possibility was first investigated in Brazil for sanitary landfills in the region of Belo Horizonte City. Tritium levels together with the content of metals present in water and the measurement of soil electrical conductivity, proved to be valuable for these studies and also as a tracer for hydrodynamic studies of the surface water in the Ressaca creek.

    Background: The Tubu are nomadic people who live in remote parts of the central Sahara, primarily in the Tibesti massif (Chad), and in both Northeastern Niger and Southern Libya. All of these areas are close to become conflict zones. However, no data about the Tubu’s health and sanitary status are currently available, which would be of major concern if humanitarian interventions would become required. Methods: In 1970, the “Mission Anthropologique Belge au Niger” (MABN) investigated a Tubu tribe named Broaya that lived at Seguedine and Djado on the northeastern rim of the Tenere desert. One hundred fifty-one adult volunteers answered an oral questionnaire and underwent a medical examination, followed by the collection of blood thin films and samples of urine and stool. The environmental fauna of medical importance was also studied. Results: Albeit 43 year-old, these results have not been previously published. The estimated age of death for fathers was approximately 56 years, and that for mothers was 60 years. On average, each married woman had had 4.7 children. The overall perinatal mortality rate was 232 ‰, the overall infant mortality rate was 153 ‰, and the overall child mortality rate was 99 ‰. The mean height was 164.1 cm and 157.4 cm, the mean weight was 50.1 kg and 47.9kg, and the mean blood pressure was 131/78 mmHg and 127/75 mmHg for males and females, respectively. The physical examination found 6 cases of blindness (4.0%). Five subjects presented with an elevated blood pressure (3.3%), and 5 (3.3%) displayed an abnormal thoracic auscultation evocative of tuberculosis or of an acute lung infection. The abdominal examination and renal palpation found 5 large masses (3.3%), and 2 subjects had a palpable enlarged spleen (1.3%). The blood thin films were fixed in methanol and subsequently examined in Toulouse. The search for blood parasites was negative. The urine samples were centrifuged and then microscopically examined in the field. No blood

    DNA methylation is critical for gene silencing and is associated with the incidence of many diseases, including cancer. Underlying molecular mechanisms of human diseases and tissue-specific gene expression have been elucidated based on DNA methylation studies. This review highlights the advantages and drawbacks of various methylation screening techniques: blotting, genomic sequencing, bisulfite sequencing, methylation-specific PCR, methylated DNA immunoprecipitation, microarray analysis, matrix-assisted laser desorption ionization time-of-flight mass spectroscopy, nanowire transistor detection procedure, quantum dot-based nanoassay, single-molecule real-time detection, fluorimetric assay, electrochemical detection, and atomic force spectroscopy. The review provides insight for selecting a method or a combination of methods for DNA methylation analysis. Convergence of conventional and contemporary nanotechniques to enumerate methylation at specific CpG sites of oncogene would fill the gap in diagnosis of cancer.

    This document is a user`s guide to establishing layering standards for drawing development. Uniform layering standards are established to exchange of AutoCAD datasets between organizations and companies. Consistency in the layering conventions assists the user through logical separation and identification of drawing data. This allows the user to view and plot related aspects of a drawing separately or in combination. The use of color and Linetype by layer is the preferred layering convention method, however to accommodate specific needs, colors and linetypes can also be assigned on an entity basis. New drawing setup files (also identified in AutoCAD documentation as Prototype drawings) use this layering convention to establish discipline drawing layers that are routinely used. Additions, deletions or revisions to the layering conventions are encourage.

    Full Text Available The article reviews the results of long-term sanitary-epidemiological examination of projects of placing of ionizing radiation (generating sources in health care institutions of Saint-Petersburg. The majority among the placed sources presented for examination was X-ray diagnostic units and sets – 35.7%, dentist X-rays – 39.4% and fluorography units – 10.8%. Mammography units and computer tomographs made 6.7% each, accelerants – 0.7%.The most frequent reasons of primary refusals to accept design documentation were: absence of calculations of protection against all placed diagnostic X-ray devices (23.6% – at placing of diagnostic X-ray sets, 16.2% – at placing of dentist devices, absence of the upper floors layouts (26.5% – at placing of dentist X-rays and absence of permitting documentation for X-ray devices (at placing of dentist X-ray devices – 22.2%.At carrying out of design activity of special importance is creation of medical and technical projects which were absent in 22.9% of presented projects and in 34.6% were replaced with technical projects. Significant drawbacks of the projects were ignoring the necessity to consider the distance from the personnel workplaces and the width of technical passes (34.0%. That was caused by the absence of corresponding documentation from suppliers of equipment for X-ray rooms.At calculation of protection against X-ray radiation in 11.3% of projects of placing X-ray diagnostic devices (sets and in 7.7% of projects of placing dentist X-ray devices, radiation directivity factors (N were determined incorrectly.Of importance is the issue of adequate choice of building and finishing materials. In 50.0% of projects of placing of diagnostic X-ray devices (sets and 37.6% of projects of placing dentist X-ray devices there were no sanitary-epidemiological conclusions regarding the building and finishing materials to confirming their feasibility for healthcare institutions.Analysis of the main stages

    In 1993, as the CWC ratification process was beginning, concerns arose that the complexity of integrating the CWC with national law could cause each nation to implement the Convention without regard to what other nations were doing, thereby causing inconsistencies among States as to how the CWC would be carried out. As a result, the author's colleagues and the author prepared the Manual for National Implementation of the Chemical Weapons Convention and presented it to each national delegation at the December 1993 meeting of the Preparatory Commission in The Hague. During its preparation, the Committee of CWC Legal Experts, a group of distinguished international jurists, law professors, legally-trained diplomats, government officials, and Parliamentarians from every region of the world, including Central Europe, reviewed the Manual. In February 1998, they finished the second edition of the Manual in order to update it in light of developments since the CWC entered into force on 29 April 1997. The Manual tries to increase understanding of the Convention by identifying its obligations and suggesting methods of meeting them. Education about CWC obligations and available alternatives to comply with these requirements can facilitate national response that are consistent among States Parties. Thus, the Manual offers options that can strengthen international realization of the Convention's goals if States Parties act compatibly in implementing them. Equally important, it is intended to build confidence that the legal issues raised by the Convention are finite and addressable. They are now nearing competition of an internet version of this document so that interested persons can access it electronically and can view the full text of all of the national implementing legislation it cites. The internet address, or URL, for the internet version of the Manual is http: //www.cwc.ard.gov. This paper draws from the Manual. It comparatively addresses approximately thirty

    To provide for temporary restrictions of the public water supply system, storage tanks are commonly installed in the domestic water systems of houses and apartment buildings in Okinawa Prefecture of Japan. To learn more about the sanitary condition and management of these water supply facilities with storage tanks (hereafter called "storage tank water systems") and the extent of bacterial contamination of water from these facilities, we investigated their usage and the existence of Aeromonas, enteric and related bacteria. Verbal interviews concerning the use and management of the storage tank water systems were carried out in each randomly sampled household. A total of 54 water samples were collected for bacteriological and physicochemical examinations. Conventional methods were used for total viable count, fecal coliforms, identification of bacteria such as Aeromonas, Enterobacteriaceae and non-fermentative Gram-negative rods (NF-GNR), and measurement of residual chlorine. On Aeromonas species, tests for putative virulence factor and an identification using 16S rRNA and rpoB genes were also performed. Water from the water storage systems was reported to be consumed directly without boiling in 22 of the 54 houses (40.7%). 31 of the sampled houses had installed water storage tanks of more than 1 cubic meter (m(3)) per inhabitant, and in 21 of the sampled houses, the tank had never been cleaned. In all samples, the total viable count and fecal coliforms did not exceed quality levels prescribed by Japanese waterworks law. Although the quantity of bacteria detected was not high, 23 NF-GNR, 14 Enterobacteriaceae and 5 Aeromonas were isolated in 42.6%, 7.4% and 3.7% of samples respectively. One isolated A. hydrophila and four A. caviae possessed various putative virulence factors, especially A. hydrophila which had diverse putative pathogenic genes such as aer, hlyA, act, alt, ast, ser, and dam. Many bacteria were isolated when the concentration of residual chlorine

    The article deals with the legal framework of an application of administrative enforcement. The authors analyzed the information about a quantity and structure of administrative violation in the sanitary and epidemiological welfare, revealed during 2009-2011 while carrying-out of federal sanitary and epidemiological surveillance by the Center for Sanitary and Epidemiological Supervision of the Ministry of Defense (TsGSEN MF RF) in military units and organizations of the Armed Forces of the Russian Federation, and applied administrative sanctions. The acquired data was compared with the same data acquired by The Federal Service for Supervision of Consumer Rights Protection and Human Well-Being (Rospotrebnadzor). The results of research give a reason to consider TsGSEN MF activity according to index of application of administrative enforcement as ineffective. It shows the significant underestimate of administrative sanctions for the failure to comply with requirements of the health legislation. The authors formulated practical recommendations for activation of legal mechanics application by the specialists of TsGSEN MF RF while carrying-out of federal sanitary and epidemiological surveillance in the Armed Forces of the Russian Federation.

    Full Text Available An improved understanding of sources and timing of water and nutrient fluxes associated with urban stream restoration is critical for guiding effective watershed management. We investigated how sources, fluxes, and flowpaths of water, carbon (C, nitrogen (N, and phosphorus (P shift in response to differences in stream restoration and sanitary infrastructure. We compared a restored stream with 3 unrestored streams draining urban development and stormwater management over a 3 year period. We found that there was significantly decreased peak discharge in response to precipitation events following stream restoration. Similarly, we found that the restored stream showed significantly lower monthly peak runoff (9.4 ± 1.0 mm d−1 compared with two urban unrestored streams (ranging from 44.9 ± 4.5 to 55.4 ± 5.8 mm d−1 draining higher impervious surface cover. Peak runoff in the restored stream was more similar to a less developed stream draining extensive stormwater management (13.2 ± 1.9 mm d−1. Interestingly, the restored stream exported most carbon, nitrogen, and phosphorus loads at relatively lower streamflow than the 2 more urban streams, which exported most of their loads at higher and less frequent streamflow. Annual exports of total carbon (6.6 ± 0.5 kg ha−1 yr−1, total nitrogen (4.5 ± 0.3 kg ha−1 yr−1, and total phosphorus (161 ± 15 g ha−1 yr−1 were significantly lower in the restored stream compared to both urban unrestored streams (p < 0.05 and similar to the stream draining stormwater management. Although stream restoration appeared to potentially influence hydrology to some degree, nitrate isotope data suggested that 55 ± 1 % of the nitrate in the restored stream was derived from leaky sanitary sewers (during baseflow, similar to the unrestored streams. Longitudinal synoptic surveys of water and nitrate isotopes along all 4 watersheds suggested the importance of urban groundwater contamination from leaky piped

    Since the appearance of Einstein's general relativity, gravitation has been associated to the space-time curvature. This theory introduced a geometrodynamic language which became a convenient tool to predict matter behaviour. However, the properties of space-time itself cannot be measurable by experiments. Taking Poincaré idea that the geometry of space-time is merely a convention, we show that the general theory of relativity can be completely reformulated in a more general setting, a generalization of Riemannian geometry, namely, the Weyl integrable geometry. The choice of this new mathematical language implies, among other things, that the path of particles and light rays should now correspond to Weylian geodesies. Such modification in the dynamic of bodies brings a new perception of physical phenomena that we will explore.

    Full Text Available INTRODUCTION : Laparoscopic splenectomy (LS is an accepted procedure for elective splenectomy. Advancement in technology has extended the possibility of LS in massive splenomegaly [Choy et al., J Laparoendosc Adv Surg Tech A 14(4, 197-200 (2004], trauma [Ren et al., Surg Endosc 15(3, 324 (2001; Mostafa et al., Surg Laparosc Endosc Percutan Tech 12(4, 283-286 (2002], and cirrhosis with portal hypertension [Hashizume et al., Hepatogastroenterology 49(45, 847-852 (2002]. In a developing country, these advanced gadgets may not be always available. We performed LS using conventional and reusable instruments in a public teaching the hospital without the use of the advanced technology. The technique of LS and the outcome in these patients is reported. MATERIALS AND METHODS : Patients undergoing LS for various hematological disorders from 1998 to 2004 were included. Electrocoagulation, clips, and intracorporeal knotting were the techniques used for tackling short-gastric vessels and splenic pedicle. Specimen was delivered through a Pfannensteil incision. RESULTS : A total of 26 patients underwent LS. Twenty-two (85% of patients had spleen size more than 500 g (average weight being 942.55 g. Mean operative time was 214 min (45-390 min. The conversion rate was 11.5% ( n = 3. Average duration of stay was 5.65 days (3-30 days. Accessory spleen was detected and successfully removed in two patients. One patient developed subphrenic abscess. There was no mortality. There was no recurrence of hematological disease. CONCLUSION : Laparoscopic splenectomy using conventional equipment and instruments is safe and effective. Advanced technology has a definite advantage but is not a deterrent to the practice of LS.

    The import substitution becomes one of the strategic tasks of national economy as a result of prolongation of economic sanctions concerning the Russian Federation of part of the USA, EU countries, Japan and number of other countries. It is not proper to be limited in import substitution only by goods because in conditions ofsanctions when access toforeign technologies is complicated Russia is needed to substitute foreign technologies by national designs in faster manner One of directions of effective import substitution is localization of production of laboratory equipment and consumables for clinical and sanitary microbiology on the territory ofthe Russian Federation and countries of Customs union. In Russia, in the field ofdiagnostic of dangerous and socially significant infections, all components for import substitution to implement gene diagnostic, immune diagnostic. bio-sensory and biochip approaches, isolation and storage of live microbial cultures, implementation of high-tech methods of diagnostic are available. At the same time, national diagnostic instrument-making industry for microbiology is factually absent. The few devices of national production more than on 50% consist of import components. The microbiological laboratories are to be equipped only with import devices of open type for applying national components. The most perspective national designs to be implemented are multiplex polimerase chain reaction test-systems and biochips on the basis of national plotters and readers. The modern development of diagnostic equipment and diagnostic instruments requires supplement of national collections of bacterial and viral pathogens and working-through of organizational schemes of supplying collections with strains. The presented data concerning justification of nomenclature of laboratory equipment and consumables permits to satisfy in fill scope the needs of clinical and sanitary microbiology in devices, growth mediums, consumables of national production

    Poor menstrual knowledge and access to sanitary products have been proposed as barriers to menstrual health and school attendance. In response, interventions targeting these needs have seen increasing implementation in public and private sectors. However, there has been limited assessment of their effectiveness. Assess the impact of providing reusable sanitary pads and puberty education on girls' school attendance and psychosocial wellbeing outcomes. A cluster quasi-randomised controlled trial was conducted across 8 schools, including 1124 girls, in rural Uganda. Schools were allocated to one of four conditions: the provision of puberty education alone; reusable sanitary pads alone; puberty education and reusable sanitary pads; and a control (no intervention). The primary outcome was school attendance. Secondary outcomes reflected psychosocial wellbeing. At follow-up, school attendance had worsened for girls across all conditions. Per-protocol analysis revealed that this decline was significantly greater for those in the control condition d = 0.52 (95%CI 0.26-0.77), with those in control schools having a 17.1% (95%CI: 8.7-25.5) greater drop in attendance than those in any intervention school. There were no differences between the intervention conditions. High rates of school drop-out and transfer meant the trial suffered from substantial participant drop-out. Intention-to-treat analyses using two different imputation strategies were consistent with the main results, with mean differences of 5.2% attendance in best-case and 24.5% in worst-case imputations. Results were robust to adjustments for clustering. There was no impact of the interventions on girls' self-reported shame or insecurity during menstruation. Results of the trial support the hypothesised positive impact of providing sanitary pads or puberty education for girls' school attendance in a developing country context. Findings must be interpreted with caution in light of poor participant retention

    Full Text Available Energy security and independence, increase and fluctuation of the oil price, fossil fuel resources depletion and global climate change are some of the greatest challanges facing societies today and in incoming decades. Sustainable economic and industrial growth of every country and the world in general requires safe and renewable resources of energy. It has been expected that re-arrangement of economies towards biofuels would mitigate at least partially problems arised from fossil fuel consumption and create more sustainable development. Of the renewable energy sources, bioenergy draws major and particular development endeavors, primarily due to the extensive availability of biomass, already-existence of biomass production technologies and infrastructure, and biomass being the sole feedstock for liquid fuels. The evolution of biofuels is classified into four generations (from 1st to 4th in accordance to the feedstock origin; if the technologies of feedstock processing are taken into account, than there are two classes of biofuels - conventional and advanced. The conventional biofuels, also known as the 1st generation biofuels, are those produced currently in large quantities using well known, commercially-practiced technologies. The major feedstocks for these biofuels are cereals or oleaginous plants, used also in the food or feed production. Thus, viability of the 1st generation biofuels is questionable due to the conflict with food supply and high feedstocks’ cost. This limitation favoured the search for non-edible biomass for the production of the advanced biofuels. In a general and comparative way, this paper discusses about various definitions of biomass, classification of biofuels, and brief overview of the biomass conversion routes to liquid biofuels depending on the main constituents of the biomass. Liquid biofuels covered by this paper are those compatible with existing infrastructure for gasoline and diesel and ready to be used in

    Crohn's disease (CD) is a multifactorial disorder of unknown cause. Outstanding progress regarding the pathophysiology of CD has led to the development of innovative therapeutic concepts. Numerous controlled trials have been performed in CD over the last years. However, many drugs have not been approved by regulatory authorities due to lack of efficacy or severe side effects. Therefore, well-known drugs, including 5-ASA, systemic or topical corticosteroids, and immunosuppressants such as azathioprine, are still the mainstay of CD therapy. Importantly, biologicals such as infliximab have shown to be efficacious in problematic settings such as fistulizing or steroid-dependent CD. This review is intended to give practical guidelines to clinicians for the conventional treatment of CD. We concentrated on the results of randomized, placebo-controlled trials and meta-analyses, when available, that provide the highest degree of evidence. We provide evidence-based treatment algorithms whenever possible. However, many clinical situations have not been answered by controlled clinical trials and it is important to fill these gaps through expert opinions. We hope that this review offers a useful tool for clinicians in the challenging treatment of CD.

    Full Text Available Psoriatic arthritis is a heterogeneous condition, the pattern of which is determined by any combination of pathology affecting peripheral joints, the enthesis and the spine. There is a paucity of evidence for most of the conventional agents used to treat psoriatic arthritis, with many of them being used on the basis of experience in rheumatoid arthritis. Herein, we summarise the evidence compiled relating to effectiveness of treatment for various manifestation of PsA. For those patients with progressive forms of arthritis who may benefit from intervention of newer biological therapies, the continued use of conventional therapy needs ever increasing scrutiny.

    Migraine is a common neurological problem, which accounts for large morbidity and disability. Non-steroidal anti-inflammatory agents and triptans are mainly used to terminate the attack of moderate to severe migraine. This study compared the safety, efficacy and pharmaco-economics of rizatriptan (5HT(IB/ID) agonist) versus conventional therapy (paracetamol 500 mg + metoclopramide 10 mg + flunarizine 10 mg + alprazolam 0.5 mg). In this study, drug combinations used in conventional therapy was indigenously designed by the neurologist. Rizatriptan was found more efficacious than conventional therapy in terminating an attack of migraine and its' associated symptoms but looking into the contra-indications, side-effects and cost of the former there has been limitation in its prescription as well as the use.

    An improved understanding of sources and timing of water and nutrient fluxes associated with urban stream restoration is critical for guiding effective watershed management. We investigated how sources, fluxes, and flowpaths of water, carbon (C), nitrogen (N), and phosphorus (P) shift in response to differences in stream restoration and sanitary infrastructure. We compared a restored stream with 3 unrestored streams draining urban development and stormwater management over a 3 year period. We found that there was significantly decreased peak discharge in response to precipitation events following stream restoration. Similarly, we found that the restored stream showed significantly lower monthly peak runoff (9.4 ± 1.0 mm d-1) compared with two urban unrestored streams (ranging from 44.9 ± 4.5 to 55.4 ± 5.8 mm d-1) draining higher impervious surface cover. Peak runoff in the restored stream was more similar to a less developed stream draining extensive stormwater management (13.2 ± 1.9 mm d-1). Interestingly, the restored stream exported most carbon, nitrogen, and phosphorus loads at relatively lower streamflow than the 2 more urban streams, which exported most of their loads at higher and less frequent streamflow. Annual exports of total carbon (6.6 ± 0.5 kg ha-1 yr-1), total nitrogen (4.5 ± 0.3 kg ha-1 yr-1), and total phosphorus (161 ± 15 g ha-1 yr-1) were significantly lower in the restored stream compared to both urban unrestored streams (p export. Given that both stream restoration and sanitary pipe repairs both involve extensive channel manipulation, they can be considered simultaneously in management strategies. In addition, ground water can be a major source of nutrient fluxes in urban watersheds, which has been less considered compared with upland sources and storm drains. Goundwater sources, fluxes, and flowpath should also be targeted in efforts to improve stream restoration strategies and prioritize hydrologic "hot spots" along watersheds where

    Full Text Available CONTEXT: The number of elderly is constantly increasing in the western world and many of this people spend the last years of their life in a nursing home with physical and/or mental disabilities. OBJECTIVE: To estimate the Health Service resource and direct costs for Community Residential Care (CRC disabled elderly people. METHODS: A retrospective observational study was conducted between January 2002 and December 2002 among all CRC (23 CRC and 1665 disabled residential elderly population REP of the Local Health Authority n° 9 of Treviso. For each CRC data regarding patients, hospitalisation, clinical analysis, general practitioner and hospital medical doctor assistance, drug utilisation were collected and analysed. RESULTS: Males were 27% and female 73% with an average age 78 and 86 years old respectively. Frequency of hospitalisation, clinical analysis and drug utilisation vary widely between the CRC and an inverse correlation is observed between cost of hospitalisation and drug plus clinical analysis. The first causes of hospitalisation are pneumonia 7.2% and cardiovascular disease 4.9% both considered preventable cause of hospitalisation. Regarding the drug consumption analysis enalapril, furosemide, omeprazole are the most used molecules with a consumption of 308, 185, 166 DDD/1000 REP/die; systemic antibiotics are the more expensive drugs with a cost of 0.3 euro/REP/die. Unexpected laxatives consumption is lower than data from literature with a 17% of the total REP exposed. Finally average annually cost for a REP in CRC is 16,445 euros and beside the direct sponsor of local health authority to the CRC hospitalisations cost are the most important (899 euros while drugs, medical assistance and sanitary material cost are similar with an annual cost of 530 euros, 492 euros, 450 euros respectively. Hypnotic and anxiolytic consumption appear to be correct with literature data with about 30% population exposed. CONCLUSION: Females are disabled

    Following the development of an experimental system to expose adult fish to low and stable concentration of pollutant over a prolonged period, the in vivo effects of hydrocarbons on sanitary status, i.e. the health status of fish with regard to chemical pollution, and immune system in sea bass, Dicentrarchus labrax were assessed. A total of 90 fish were acclimated for 15 days, then 45 fish were exposed to the water soluble fraction (WSF) of Arabian crude oil, similar to a complex pollution by hydrocarbons chronically observed in situ in estuaries, while the 45 other control fish sustained the same experimental conditions in clean seawater. After 21 days of exposure, 30 contaminated and control fish were sampled, then 30 other fish were collected after a 15 day recovery period in clean sea water. PAH concentrations in crude oil, WSF, muscles and bile were measured by gas chromatography coupled with mass spectrometry analysis. White blood cell counts and differential leucocyte counts were determined by classical haematology methods. Cell mortality and phagocytosis activity of leucocytes were analyzed by flow cytometry. Haemolytic alternative complement activity and stress parameters were analyzed in blood plasma by spectrophotometry. After a 21 day exposure period to a mixture of 41 parent/alkylated-PAHs (835 ± 52/85 ± 1 5 ng L(-1)). Fish flesh was contaminated by a bioconcentration of naphthalene very closed to the Reference Dose for Oral Exposure estimated by US-EPA's Integrated Risk Information System, causing a potential risk for human consumers. A leucopenia due to a lymphopenia, a rise in leucocyte mortality and a decrease in phagocytosis activity were noted in contaminated fish compared to controls. All these results may be explained by the damage to membrane cells integrity by uptake of PAHs and suggested an impairment of specific and nonspecific immune systems. After a 15 day recovery period, effects were reversible for sanitary status and an offset in

    2012-09-01

    Calpains are intracellular Ca(2+)-dependent Cys proteases that play important roles in a wide range of biological phenomena via the limited proteolysis of their substrates. Genetic defects in calpain genes cause lethality and/or functional deficits in many organisms, including humans. Despite their biological importance, the mechanisms underlying the action of calpains, particularly of their substrate specificities, remain largely unknown. Studies show that certain sequence preferences influence calpain substrate recognition, and some properties of amino acids have been related successfully to substrate specificity and to the calpains' 3D structure. The full spectrum of this substrate specificity, however, has not been clarified using standard sequence analysis algorithms, e.g., the position-specific scoring-matrix method. More advanced bioinformatics techniques were used recently to identify the substrate specificities of calpains and to develop a predictor for calpain cleavage sites, demonstrating the potential of combining empirical data acquisition and machine learning. This review discusses the calpains' substrate specificities, introducing the benefits of bioinformatics applications. In conclusion, machine learning has led to the development of useful predictors for calpain cleavage sites, although the accuracy of the predictions still needs improvement. Machine learning has also elucidated information about the properties of calpains' substrate specificities, including a preference for sequences over secondary structures and the existence of a substrate specificity difference between two similar conventional calpains, which has never been indicated biochemically.

    An analysis of modern sanitary-epidemiological status of railway transport is presented. The mean index of occupational morbidity in railway transport workers in recent years is 1.2 cases per 10 thousand railway workers. Workers of locomotive brigades (locomotive drivers and their assistants), in whom occupational sensorineural hearing loss was predominantly revealed (78.3 +/- 3.4%) accounted for 30-40% of cases out of the total number of occupational morbidity in railway transport workers. Water samples from the sources of centralized and noncentralized water supply did not meet health standards for microbiological parameters in the 14-18%, and from the water pipes in 4-6% of cases. Suggestions for improving sanitary-hygiene monitoring in railway transport have been given.

    Full Text Available In order to fulfill the legal requirements for the transition to the new risk-based model of the state control (supervision in the Federal Service for Consumer Rights Protection and Human Welfare, the methodical approaches to the classification of economic entities and activities of potential risk of injury have been developed. The risk assessment takes into account the frequency of violations of sanitary legislation, the severity of the consequences of these violations for the health and extent of negative effects, which is estimated in terms of population under the influence of the economic entity. Algorithms and methods for calculating the exposed population: workers, consumers, including consumer food products, non-food products and services; residents of settlements under the negative impact of air pollution, water and soil, have been developed. Regional and federal registries of objects for sanitary and epidemiological supervision are formed. Testing of the risk-based approaches in the regions allowed excluding the low risk harm objects when forming the audit plans for 2016, due to what the number of planned inspections all over country was reduces by more than 20 %. The basic directions of further improvement of the risk-based model of sanitary and epidemiological surveillance: its extension to the system of technical regulation and consumer protection; scientific substantiation of its volume, content and laboratory support of the scheduled inspections of objects belonging to different classes of health risk; improving procedures and methods for evaluating the effectiveness and efficiency of risk-based supervisory activities; creation of an effective system of risk communication between the sanitary and epidemiological surveillance, economic entities, public organizations and associations and civil society.

    "The Sanitary Bureau of the Home Ministry Magazine," in which Sensai Nagayo served as the Director of the Sanitary Bureau of the Home Ministry also took part, provide valuable historical materials regarding the Sanitary Bureau at the beginning of the Meiji era. This paper reports on the hygiene policy plan at that time by using this magazine. That is, the plan considered the facts about the regional society when executing it, though it was based on the hygiene system assumed to be an ideal "Isei". In that case, it involved not only the police but also the doctors and pharmacists as practitioners who practiced hygienic clerical work, and it aimed at bringing the functions of the hygienic clerical work to the local populace. However, neither the doctors nor pharmacists came to play a role when cholera was prevalent in 1877. Rather, at that time, the police practiced the hygienic clerical work, and the police came to be parts of the hygienic policy thereafter, as indispensable practitioners.

    Iodine is an essential trace element implicated in synthesis of thyroid hormones. Iodine requirements vary throughout life. This iodine requirement is increased during pregnancy and breastfeeding. In a previous study carried out by our group in 2008, we detected an iodine-deficient area in the province of Huelva, specially in district Sierra de Huelva-Andévalo by means of neonatal TSH determinations. To reinforce the iodine supplementation campaign and its impact on their newborns in order to assess nutrition iodine status in pregnant women using questionnaire and ioduria determination. This study has been jointly carried out by Congenital Hypothyroidism Unit of the Clinical Biochemistry Department of the Virgen Macarena University Hospital (Seville) and the Gynecology and Clinical Analysis Unit of the Río Tinto Hospital (Huelva) during two years. We studied 313 pregnant women. All of them filled out a personal questionnaire to know the iodine nutritional status in their area. Ioduria was determinated by high-resolution liquid chromatography. Data from pregnant women and results of the studied variables were analyzed with SPSS v13.0. Pregnant women from the sanitary district Sierra de Huelva-Andévalo present a median for ioduria which corresponds to an insufficient iodine intake according to the WHO classification. The questionnaires suggest that this iodine deficiency is consequence of an insufficient iodine intake and a low adherence to the treatment.

    To measure the degree of stress among medical residents at a Third Level Hospital in Mexico City during the sanitary contingency caused by the AH1N1 influenza virus. A transversal descriptive study with a non-probabilistic sample of 99 medical residents with different fields of specialization related to respiratory medicine. Researchers applied the Maslach Burnout Inventory questionnaire to evaluate three dimensions: emotional fatigue, depersonalization, and personal fulfillment. The survey was self-administered and anonymous, and the study was conducted during the first AH1N1 influenza virus outbreak (April 23 to May 10, 2009). During that period, the hospital underwent a process of reorganization that included cancelling vacation periods for all medical residents and adjusting duty rosters. The highest proportion of medical residents with burnout syndrome was those in their second year of specialization in the area of pneumology. Results also showed that medical residents under 30 years of age had a higher probability of presenting burnout syndrome. No significant differences were found regarding the residents’ place of origin.

    Full Text Available The objective of this study was to evaluate the hygienic-sanitary conditions of hospital nutrition and dietary services using external and internal auditors. Eleven hospitals were evaluated for their nutrition and dietary services using an evaluation checklist based on food safety requirements in the current legislation. The checklist was applied by an internal auditor (a technical supervisor and an external auditor (a professional with experience in food services between August and October 2011. According to the number of items on the evaluation checklist that were considered adequate, the hospital facilities were ranked as excellent, good, regular, bad, or very bad. The results obtained by the auditors were compared. According to these results, it can be said that most of the hospital nutrition and dietary services were rated as good for overall quality by the internal auditor, while the external auditor classified them as Regular. There was a clear difference between the evaluations of the auditors, both in terms of the number of items considered adequate and the overall requirements' average score. It can be concluded that hospital nutrition and dietary services should meet safety requirements in order to provide food. These facilities should have external audits conducted as a way to prevent routine problems from being perpetuated.

    The study described in this article aimed at establishing a baseline assessment of the sanitary status of ice and guest rooms within Canadian hotels. Collectively, 54 hotel rooms belonging to six different national chains were sampled. High-contact surfaces (comforter, alarm clock, bedside lamp, TV remote, bathroom countertop, faucet, and toilet seat) were sampled using adenosine triphosphate (ATP) swabs and replicate organism detection and counting plates. ATP swab readings ranged from 2.12 to 4.42 log relative light units. Coliforms were recovered from 36% of surfaces with high prevalence being recovered from the comforter, TV remote, bathroom countertop, faucet, and toilet seat. Oxacillin-resistant bacteria were recovered from 19% of surfaces with 46% of isolates confirmed as methicillin-resistant Staphylococcus aureus. Two toxigenic Clostridium difficile isolates were recovered in the course of the study. Collectively, 24% of the ice samples harbored coliforms with a single sample testing positive for E. coli. The authors' study demonstrates that hotel rooms represent a potential source of community-acquired infections and the need for enhanced sanitation practices.

    Full Text Available The creation of superior courses related to the environmental area has increased surprisingly in Brazil in the last decade and in the beginning of the 21st century, situation possibly stimulated by the policy of increase of the superior education, courses, and offered vacancies propagated by the Education Ministry in the last years as well as by the increasing environmental preoccupation and the consequent addition in the search for qualified professionals in this area. In this context, new undergraduation courses in Environmental Engineering and Environmental Management have emerged to form professionals with similar habilitation to other already established professions such as the sanitary engineer and the ecologist as well as the other traditional professionals (engineers, geologists, biologists, geographers, chemist. Because of that, there is, currently, a very offensive discussion in the organs of the class, at the education institutes, and in the general society about the area of actuation of the professionals that works in the environmental area. In the present article it is shown a data survey about superior courses (graduation, technology or sequences of environment in Brazil as well as the norms and legislations that regulate the performance of these professionals. The aim is to analyze the basic questions related to each course, and to work as subsidy to further analyses and discussions.

The natural background radiation level can vary by tens and hundred times even for similar products, while areas of their application can differ from jewelry to medicine. However, normative documents (guidelines on the content of natural radionuclides in such products have not been yet created. To ensure radiation safety in the use of these products, the dose limit is set: the effective annual dose due to direct use of these products must not exceed 0.1 mSv. This article discusses issues related to the application of the dedicated sections of the documents OSPORB-99/2010 and SanPiN 2.6.1.2800-10 during sanitary-epidemiological assessment of the products, for which regulations on the content of natural radionuclide’s are not created. Possible scenarios of humanexposure when using these products with the primary purpose are considered. Based on the limit of 0.1 mSv annual effective dose, the criteria for a rapid compliance assessment of the radiological characteristics of the individual groups of these products are proposed.

    In 2016, the U.S. Fish and Wildlife Service, U.S. Geological Survey, and U.S. Army Corps of Engineers undertook a field study in the Chicago Sanitary and Ship Canal near Romeoville, Illinois to determine the influence of tow transit on the efficacy of the Electric Dispersal Barrier System (EDBS) in preventing the passage of juvenile fish (total length return current of water flowing between the tow and the canal wall that typically travels opposite the direction of tow movement, and cause a decrease in the voltage gradient of the barrier of up to 88%. Return currents and decreases in voltage gradients induced by tow passage likely contributed to the observed fish passage through the EDBS. The efficacy of the EDBS in preventing the passage of small, wild fish is compromised while tows are moving across the barrier system. In particular, downbound tows moving through the EDBS create a pathway for the upstream movement of small fish, and therefore may increase the risk of transfer of invasive fishes from the Mississippi River Basin to the Great Lakes Basin.

    Full Text Available Paca (Cuniculus paca Linnaeus, 1766 rearing has shown development in all Latin America countries. Fresh feces samples were collected from the soil and analyzed by Willis Mollay and Hoffmann’s techniques, aiming at accompanying the sanitary management, determining the prevalence of gastrointestinal parasites, and their respective load, of pacas raised in captivity, and evaluating parasite control strategies, between the months of November/2012 and June/2013. A McMaster’s camera was used for quantification. The reading was accomplished by optical microscopy with 25x and 40x lenses, which revealed 21,433 eggs per gram of feces (EPG, with an average of 2,679,12 (± 41.0 Strongyloides spp., and 3,325 EPG, with average of 415.6 (± 57.0 Trychuris spp. Besides, 482,101 oocytes per gram of feces (OPG were found, with an average of 60,263 (± 15.93 Eimeria spp., and 51 larvae of Strongyloides spp., with an average of 6.3 (± 6.86 larvae. Two eggs of Hymenolepis diminuta were identified in only one stall. An anthelminthic (albendazole 10% and trimethopim associated with sulfadiazine were used to treat the disease. We concluded the great index of parasitic infestation presented by the animals, in spite of the anthelminthic treatments, can be associated with the rainfall rates observed, the physical conditions of the instalations, as well as the adequate cleaning and sanitization of the facilities.

    An inventory of material and energy consumption during the construction and operation (C&O) of a typical sanitary landfill site in China was calculated based on Chinese industrial standards for landfill management and design reports. The environmental impacts of landfill C&O were evaluated through life cycle assessment (LCA). The amounts of materials and energy used during this type of undertaking in China are comparable to those in developed countries, except that the consumption of concrete and asphalt is significantly higher in China. A comparison of the normalized impact potential between landfill C&O and the total landfilling technology implies that the contribution of C&O to overall landfill emissions is not negligible. The non-toxic impacts induced by C&O can be attributed mainly to the consumption of diesel used for daily operation, while the toxic impacts are primarily due to the use of mineral materials. To test the influences of different landfill C&O approaches on environmental impacts, six baseline alternatives were assessed through sensitivity analysis. If geomembranes and geonets were utilized to replace daily and intermediate soil covers and gravel drainage systems, respectively, the environmental burdens of C&O could be mitigated by between 2% and 27%. During the LCA of landfill C&O, the research scope or system boundary has to be declared when referring to material consumption values taken from the literature; for example, the misapplication of data could lead to an underestimation of diesel consumption by 60-80%.

  2. Leachate treatment system using constructed wetlands, Town of Fenton sanitary landfill, Broome County, New York. Final report

    Energy Technology Data Exchange (ETDEWEB)

    1993-11-01

    Municipal sanitary landfills generate leachate that New York State regulations require to be collected and treated to avoid contaminating surface water and groundwater. One option for treating leachate is to haul it to municipal wastewater treatment facility. This option may be expensive, may require excessive energy for transportation, and may require pretreatment to protect the receiving facility`s processes. An alternative is on-site treatment and discharge. Personnel from the Town of Fenton, New York; Hawk Engineering, P.C.; Cornell University; and Ithaca College designed, built, and operated a pilot constructed wetland for treating leachate at the Town of Fenton`s municipal landfill. The system, consisting of two overland flow beds and two subsurface flow beds has been effective for 18 months in reducing levels of ammonia (averaging 85% removal by volatilization and denitrification) and total iron (averaging 95% removal by precipitation and sedimentation), two key constituents of the Fenton landfill`s leachate. The system effects these reductions with zero chemical and energy inputs and minimal maintenance. A third key constituent of the leachate, manganese, apparently passes through the beds with minimal removal. Details and wetland considerations are described.

    The Sanitary and Phytosanitary( SPS) measures are technical regulations,standards,and requirements closely related to food safety,plant and animal health,and environmental safety,aiming to prevent disease,pests,pathogens and other alien risk from entering China.Pork is favorite meat for Chinese consumers; its safety directly concerns the safety of whole food supply chain with rapid increasing of pork import. This paper analyzed SPS management system of swine and pork import,and evaluated SPS efficiency of swine industry in China from SPS notification number,swine health situation,and pork import standard. The study found that as for SPS notification number and chemical residue control standard,China’s SPS protection level is relatively high,while the control level of swine diseases is still low. In China,SPS management system has the problem of involving multiple authorities and poor coordination among them,leading to some standards lacking scientific basis and low enforcement.

    There are many ways to understand self-management. They vary from Government-dependent technical-administrative meanings (i.e. hospital self-management, in the context of health reform in Chile), to those related to efforts to abolish the State. Thus, the "self-management" concept was developed from the very beginning by the anarchist movement as one of its organizational principies. Henee, there is a need to break myths and prejudices about anarchist philosophy seen as a synonym of chaos, and to review its deeply constructive aspects and its highly moral character, hand in hand with genuine self-management in health. In this context, the work of Juan Gandulfo, a physician and anarchist, in the management of the Worker Polyclinic of the Industrial Workers of the World (IWW) and its diffusion media "The sanitary page" must be emphasized. The aim of this paper is to review the history of particular initiatives in self management, complementing them with some biographical aspects of Dr. Gandulfo's life.

    1993-01-01

    A technique for modeling the multilayer perceptron (MLP) neural network, in which input and hidden units are represented by polynomial basis functions (PBFs), is presented. The MLP output is expressed as a linear combination of the PBFs and can therefore be expressed as a polynomial function of its inputs. Thus, the MLP is isomorphic to conventional polynomial discriminant classifiers or Volterra filters. The modeling technique was successfully applied to several trained MLP networks.

    Magnetic resonance angiography is increasingly used as a non-invasive method in the evaluation of coarctation of the aorta. The aim of this study was to compare aortic dimensions calculated by MR angiography and those obtained by more conventional MR sequences and conventional angiography. Twenty-six consecutive patients with coarctation underwent three-dimensional MR angiography. Two independent observers retrospectively evaluated three aortic segments, site of coarctation, presence of aneurysm and existence of collateral circulation. Three aortic segments were also compared with those obtained on classical MR sequences and conventional angiography. The MR angiography was successfully performed in all showing 1 aneurysm and collateral circulation in 8 patients. Almost perfect intraobserver (r{sup 2}>0.91) and excellent interobserver (r{sup 2}>0.80) reliabilities were obtained for each aortic segment no matter which MR sequence was employed. Similarly, mainly excellent (r{sup 2}>0.80) concordance analysis was observed between MR angiography measurements and those calculated by either spin-echo/gradient-echo sequences or conventional angiography. This study demonstrates that MR angiography is a fast, accurate and reproducible method in the evaluation of coarctation of the aorta. It provides excellent anatomic information and reliably detects collateral vessels. Magnetic resonance angiography could probably replace the conventional angiography and will provide an additional diagnostic value in combination with turbo spin-echo sequence. (orig.)

    In this work, an innovative methodology for the treatment of landfill leachates, after aerobic lagooning, is proposed and adjusted at pilot-scale. This methodology involves an aerobic activated sludge biological pre-oxidation (ASBO), a coagulation/sedimentation step (240mgFe(3+)/L, at pH4.2) and a photo-oxidation through a photo-Fenton (PF) reaction (60mg Fe(2+), at pH2.8) combining solar and artificial light. The ASBO process applied to a leachate after aerobic lagooning, with high organic and nitrogen content (1.1-1.5gC/L; 0.8-3.0gN/L) and low biodegradability (BOD5/COD =0.07-0.13), is capable to oxidise 62-99% of the ammonium nitrogen, consuming only the affluent alkalinity (70-100%). The coagulation/sedimentation stage led to the humic acids precipitation, promoting a marked change in leachate colour, from dark-brown to yellowish-brown (related to fulvic acids), accompanied by a reduction of 60%, 58% and 88% on DOC, COD and TSS, respectively. The PF system promoted the degradation of the recalcitrant organic molecules into more easily biodegradable ones. According to Zahn-Wellens biodegradability test, a leachate with 419mg DOC/L after coagulation, would have to be photo-oxidized until DOC 60%. The PF step cost to treat 100m(3)/day of leachate was 6.41€/m(3), combining 1339m(2) of CPCs with 31 lamps. Copyright © 2016 Elsevier B.V. All rights reserved.

    2012-09-01

    The present study utilized a multi-criteria evaluation (MCE) method in a geographical information systems (GIS) environment to evaluate the suitability of potential landfill sites in Northern Cyprus. To determine the most suitable landfill site, one of the MCE techniques, called analytical hierarchy process (AHP), was combined with a GIS to examine 12 criteria: distance from waste generation centres; distance from roads; slope; distance from surface waters; distance from groundwater areas; distance from environmentally sensitive areas; vegetation types; soil productivity; soil permeability; distance from settlements; distance from cultural sites; distance from stone quarries. The relative importance weights of these criteria were estimated using AHP and criteria maps were developed by using GIS spatial analysis. At the final stage two different suitability maps were produced using two different groups of weights. The first group suitability map had 11 052 (ha) with high suitability class, whereas the high suitability areas decreased to 5982 (ha) in the second group. Moreover, the seven potential sites identified within the first group decreased to four in the second suitability map. However, potential sites such as Gungor, Degirmenlik, Kirklar and Cayonu had similarities with higher suitability values and these same locations were regarded as suitable according to the both first and second suitability map results.

    Open dumping is the most common practice for the disposal of urban solid wastes in the least developed regions of Africa, Asia and Latin America. Sanitary landfill design and operation has traditionally focused on large cities, but cities with fewer than 50,000 in population can comprise from 6% to 45% of a given country's total population. These thousands of small cities cannot afford to operate a sanitary landfill in the way it is proposed for large cities, where heavy equipment is used to spread and compact the waste in daily cells, and then to excavate, transport and apply daily cover, and leachate is managed with collection and treatment systems. This paper presents an alternative approach for small cities, known as the semi-mechanized trench method, which was developed in Villanueva, Honduras. In the semi-mechanized trench method a hydraulic excavator is used for 1-3 days to dig a trench that will last at least a month before it is filled with waste. Trucks can easily unload their wastes into the trench, and the wastes compact naturally due to semi-aerobic biodegradation, after which the trenches are refilled and covered. The exposed surface area is minimal since only the top surface of the wastes is exposed, the remainder being covered by the sides and bottom of the trench. The surplus material from trench excavation can be valorized for use as engineering fill onsite or off. The landfill in Villanueva has operated for 15 years, using a total land area of approximately 11 ha for a population that grew from 23,000 to 48,000, with a land requirement of 0.2m(2)/person year, a cover to waste ratio of 0.2, and an estimated soil surplus of 298,000 m(3) that is valorized and used onsite. The landfill has been operated solely by the municipality with an operational cost in 2010 estimated at US$4.60 per ton. A modified water balance analysis at Villanueva shows negligible leachate generation from covered trenches and 700 m(3)/yr (60 m(3)/ha yr) from the two open
