    1985-07-01

    The government of the Yemen Arab Republic does not have a population policy, but promotes family planning for health reasons since one of its goals is to reduce maternal and child mortality and morbidity. The 2nd 5-Year Plan (1982-86) aims for increased gross domestic product and per capita income, regional development, infrastructure development, job creation, and human resources mobilization. The population increased from 4.8 million in 1970 to 5.8 million in 1980 and is projected to reach 6.5 million by 1985 (indicating a 2.4% growth rate from 1980-1985). Life expectancy is 44 years for both sexes; infant mortality now stands at a high 156/1000 due largely to early marriage and little maternal care. The government concentrates on improving health care, mainly through its national health plans, by emphasizing immunization, education, and training doctors abroad. Current total fertility is 6.7, the birth rate is 48.5/1000, and the average age at marriage for girls is 13. Contraceptives and sterilization are available; abortion for contraceptive purposes is illegal. Up to 30% of Yemen's labor force may have emigrated to neighboring Gulf states and Saudi Arabia. The shortage in labor is partially made up by immigrants from the People's Democratic Republic of Yemen, but the government still considers emigration too high since many of those who leave are the most skilled. There is no policy on international migration, due to the great value of remittances, but the government would like to encourage return migration. Yemen's urban population increased from 1.9% in 1950 to 15.3% in 1980. 4/5 of the population live in 5 of Yemen's 10 governorates. The government's policy seeks to strengthen the agricultural sector, improve living quality in rural areas, build up a balanced regional infrastructure, and establish more educational opportunities in small cities and villages.

    West Africa, particularly Niger Republic is home to thousands of tourists annually. The vast Saharan desert and it's numerous oases in the northern parts of the Republic are a hot attraction on their own. However, in a recent survey of medicinal springs within the West African sub-region, the only hot spring in this country known locally for its therapeutic egress was analyzed. Located about 160km West of Agadez, the "Tafadek" spring with a yield of over 5l/s and temperature of about 50oC, rich in fluoride and silica is a specific water with capacity for application in balneotherapy for the treatment of orthopaedic, rheumatological, neurological, urinary tract infections, and osteoporosis. If the Tafadek spring is developed into a modern health resort promoting balneotherapy, health (balnear) tourism which is non-existent in Niger Republic today could kick start a new dawn in the health/economic development of the nation and the sub-region at large.

    Urbanization in African cities has major impact on malaria risk. Niamey, the capital of the Republic of Niger, is situated in the West African Sahel zone. The short rainy season and human activities linked with the Niger River influence mosquito abundance. This study aimed at deciphering the factors of distribution of urban malaria vectors in Niamey. The distribution of mosquito aquatic stages was investigated monthly from December 2002 to November 2003, at up to 84 breeding sites, throughout Niamey. An exploratory analysis of association between mosquito abundance and environmental factors was performed by a Principal Component Analysis and confirmed by Kruskall-Wallis non-parametric test. To assess the relative importance of significant factors, models were built for Anopheles and Culicinae. In a second capture session, adult mosquitoes were collected weekly with pyrethrum sprays and CDC light-traps from June 2008 to June 2009 in two differentiated urban areas chosen after the study's first step. Members of the Anopheles gambiae complex were genotyped and Anopheles females were tested for the presence of Plasmodium falciparum circumsporozoite antigens using ELISA. In 2003, 29 % of 8420 mosquitoes collected as aquatic stages were Anopheles. They were significantly more likely to be found upstream, relatively close to the river and highly productive in ponds. These factors remained significant in regression and generalized linear models. The Culicinae were found significantly more likely close to the river, and in the main temporary affluent stream. In 2009, Anopheles specimens, including Anopheles gambiae s.l. (95 %), but also Anopheles funestus (0.6 %) accounted for 18 % of the adult mosquito fauna, with a large difference between the two sampled zones. Three members of the An. gambiae complex were found: Anopheles arabiensis, Anopheles coluzzii, and An. gambiae. Nineteen (1.3 %) out of 1467 females tested for P. falciparum antigen were found positive. The

    1959-04-15

    In response to a request from the UAR Government, the IAEA sent a Soviet expert, to make an on-the-spot study of data on the mining and processing of phosphates in the UAR and to examine the possibility of recovering uranium from the phosphate ores. In his report to the IAEA Director General, he has listed the following conclusions: 1.The uranium content of run-of-the-mine phosphoric ores in the United Arab Republic is very low and the recovery of uranium from them is therefore hardly likely to be an economic proposition. 2. It is essential to press on with prospecting work in order to discover richer uranium deposits and regions of phosphoritic ores. 3. It is essential to organize scientific research work on the recovery of uranium from the various types of uranium-bearing phosphoritic ores in the United Arab Republic, using mechanical concentrating methods and chemical processing methods. 4. The Agency could assist in carrying out this work either by sending as many technicians as a required to help in planning and undertaking the research work in the UAR or by getting appropriate Member States to carry out this work on preliminary samples of ore with the participation of representatives of the UAR

    Full text: 1. Introduction: It is interesting to examine how the need to develop and maintain skills in term of human resources was dealt with Niger's nuclear sector. Although the country is one of poorest in the world, some insight can be derived from its experience. The Niger politics and strategies for both demand and supply side of human resources in the nuclear sector are to promote tangible socio-economic impact to the achievement of major sustainable development priorities. Member state of International Atomic Energy Agency (IAEA) since 1968, Niger was started during the same year, its nuclear activities by extraction and processing uranium from open pit mine of SOMAIR. With 2960 tons of uranium from two big mines, Niger becomes the 3rd world producer. Training and education are critical components of the development of human resources related to the nuclear sector in Niger Republic. The country has gone through a number of initiatives to consolidate its legal framework concerning radiation safety. The National Centre of Radio Protection (NCRP), under the Ministry of Heath, is operational and is responsible for national regulatory activities programme, while the Ministry of Mines and Energy regulates uranium mining and milling activities. Both regulatory authorities need to develop their human resources to be able to inspect users and enforce regulatory requirements in all areas. 2. Human resources suppliers: In order to establish a pool of competency, mining companies send their workers to France for education and training. Incentives (good social condition, salaries etc) were provided to attract people to work in nuclear programme. Many foreign professionals were short-term consultants, but many of them are employed by the companies, forming a pool of well-skilled and motivated professionals. One way that was used to enhance and maintain the pool of trained professionals was the technical co-operation with the IAEA In this regard, we thank IAEA who has

  1. Perspectives of application of isotope techniques in hydrology in the Syrian Arab Republic

    1986-01-01

    The Syrian Arab territories are located in the warm moderate region, under arid and semi-arid conditions. In spite of the occurrence of main springs and permanent rivers, groundwater resources available are a limiting factor for socio-economic development in several Syrian regions. Investigation and development of these resources are facing serious problems, for which the application of isotope and nuclear techniques could be a significant process and a deterministic tool. So far, and on the light of current applications, the Syrian Arab Republic is already involved in the isotopic hydrology sector, and so it is needful to set up, in the near future, a relevant unit, on a centralized basis covering the concerned authorities demands, under co-ordinated and integrated conditions. The international co-operation would be of a concrete importance in this respect, to provide the mentioned unit with equipment, training of scientific and technical staff, and consultancy services during the period of establishment. 14 refs.

    2004-04-01

    Full Text Available The purpose of this paper is to examine how ICT development is progressing and what kind of political and social effects have been occurring (or could occur in the near future in Middle Eastern Arabic countries. To examine this theme, this paper will adopt the Syrian Arab Republic as a case. To understand the Syrian government's policy toward the ICT development, it is necessary to examine the domestic political situation, since they are closely related. Under the Bashar Al- Asad's regime, we can confirm several reasons why they have to move forward on their ICT development policy and why it has become a crucial issue, which they cannot evade, as they had done under the previous regime, Hafez Al- Asad's regime. The situation that the Syrian government is facing right now is known by the term, "Dictator's Dilemma". This paper tries to provide bases in order to examine and explore this dilemma in Syria. Also, when we examine ICT development in Syria, it is important to consider the ICT support policies, which are mainly conducted by OECD countries and international organizations and stem from the issue of "Digital Divide". This is why international assistances could have great effect on ICT development in Syria. As a provisional conclusion of this paper, I will summarize how we can understand the current situation of ICT development in Syria, and I will also comment on the future prospect of the dilemma that the Syrian government is facing at the present time.

    Dried seeds and nuts are widely consumed by indigenous populations of the western Sahel, especially those who inhabit rural areas. In light of the need for quantitative information regarding the content of particular nutrients in these plant foods, we collected dried pumpkin (Cucurbita spp) seeds and nuts of Cyperus esculentus in the Republic of Niger and analyzed them for their content of essential amino acids, minerals and trace elements, and fatty acids. On a dry weight basis, pumpkin seed contained 58.8% protein and 29.8% fat. However, the lysine score of the protein was only 65% relative to the FAO/WHO protein standard. The pumpkin seed contained useful amounts of linoleic (92 microg/g dry weight) and the following elements (on a microg per g dry weight basis): potassium (5,790), magnesium (5,690), manganese (49.3), zinc (113), selenium (1.29), copper (15.4), chromium (2.84), and molybdenum (0.81), but low amounts of calcium and iron. Except for potassium (5,573 microg/g dry weight) and chromium (2.88 microg/g dry weight), the C. esculentis nuts contained much less of these same nutrients compared to pumpkin seeds. In conclusion, pumpkin seeds represent a useful source of many nutrients essential to humans. The data in this report should of practical value to public health officials in rural areas of sub-Saharan Africa.

    This study investigated the prevalence of iron-deficiency anaemia, glucose-6-phosphate dehydrogenase (G6PD) deficiency and β-thalassaemia trait among Arab migrating nomad children in southern Islamic Republic of Iran. Blood samples were analysed from 134 schoolchildren aged child had G6PD deficiency. A total of 9.7% of children had HbA2 ≥ 3.5 g/dL, indicating β-thalassaemia trait (10.8% in females and 7.8% in males). Mean serum iron, serum ferritin and total iron binding capacity were similar in males and females. Serum ferritin index was as accurate as Hb index in the diagnosis of iron-deficiency anaemia. A high prevalence of β-thalassaemia trait was the major potential risk factor in this population.

    The FMPP is a fuel plates manufacturing plant for test reactors. This facility was designed, constructed in El Cairo and turned-key handled by INVAP SE to the Arabian Republic of Egypt. In this project, CNEA participated in the transference of technology, elaboration of documents, training of Egyptian personnel and technical services during the setup of the facility in El Cairo. These tasks were undertaken by UPMP (Uranium Powder Manufacturing Plant) and ECRI (Research Reactors Fuel Elements Plant) personnel. Both plants in CNEA served as a FMPP design basis. During the setup of the facility a fuel element with natural uranium was firstly manufactured and then another one using uranium with 20% enrichment. In this paper the responses of the system regarding safety, after finishing the first two stages of manufacturing, are analyzed and evaluated. (author)

    Full Text Available Bien que connue depuis les temps les plus anciens, la dépression de Wadi el Natroun n'avait jamais été prospectée autrement que pour sa richesse en sels minéraux. C'est en 1977 que les auteurs, cherchant à savoir s'il existait des lacs naturels à Spirulines en République Arabe d'Égypte, découvrirent dans la dépression de Wadi el Natroun certains lacs comme Abou Gobara et El Khadra où croissaient spontanément les algues spirulines. Le climat du site, l'origine et la composition des eaux, ainsi que la concentration en algues, ont été étudiés afin d'estimer la productivité du site en vue d'une éventuelle exploitation industrielle. L'exploitation de ces lacs permettrait de mettre en valeur le site de Wadi el Natroun par la production d'une substance très riche en protéine pour l'alimentation humaine dont à tant besoin la République Arabe d'Égypte. Even though it has been known from olden days, the depression of Wadi el Natrun had never been prospected other than for its wealth of mineral salts. It was in 1977 that the authors began searching for natural lakes with Spirulina algae in the Arab Republic of Egypt and, in the depression of Wadi el Natrun, discovered varions lakes such as Abu Gobara and El Khadra where Spirulina algae grew in a natural state. The climate of the site, the original and composition of the water as well as the algae concentration were analyzed to evaluate the productivity of the site for eventual industrial exploitation. The exploitation of these lakes would give value to the Wadi el Natrun site by producing a very protein-rich substance for human nourishment which the Arab Republic of Egypt needs so badly.

    2013-01-01

    The past year witnessed considerable turbulence in the Arab world-in this case, Syria, a lower middle-income country with a record of a strong public health infrastructure. This paper explores the current challenges facing its health system from reforms, civil strife and international sanctions all of which we argue have serious implications for population health. The health sector in Syria was little known, and until recently, it was well integrated to provide preventive and specialized care when needed. Regionally, it was one of the few countries ready and capable of addressing the challenges of demographic and epidemiologic transition with a long-standing emphasis on primary care and prevention, unlike most countries of the region. This context has changed dramatically through the recent implementation of reforms and the current civil war. Changes to financing, management and the delivery of health service placed access to services in jeopardy, but now, these are compounded by the destruction from an intractable and violent conflict and international sanctions. This paper explores some of the combined effects of reforms, conflict and sanctions on population health. Copyright © 2013 John Wiley & Sons, Ltd.

    Full Text Available The diversity of cattle in Niger is predominantly represented by three indigenous breeds: Zebu Arabe, Zebu Bororo and Kuri. This study aimed at characterizing the genetic diversity and relationship of Niger cattle breeds using short tandem repeat (STR marker variations. A total of 105 cattle from all three breeds were genotyped at 27 STR loci. High levels of allelic and gene diversity were observed with an overall mean of 8.7 and 0.724 respectively. The mean inbreeding estimate within breeds was found to be moderate with 0.024, 0.043 and 0.044 in Zebu Arabe, Zebu Bororo and Kuri cattle respectively. The global F statistics showed low genetic differentiation among Niger cattle with about 2.6 % of total variation being attributed to between-breed differences. Neighbor-joining tree derived from pairwise allele sharing distance revealed Zebu Arabe and Kuri clustering together while Zebu Bororo appeared to be relatively distinct from the other two breeds. High levels of admixture were evident from the distribution of pairwise inter-individual allele sharing distances that showed individuals across populations being more related than individuals within populations. Individuals were assigned to their respective source populations based on STR genotypes, and the percent correct assignment of Zebu Bororo (87.5 to 93.8 % was consistently higher than Zebu Arabe (59.3 to 70.4 % and Kuri (80.0 to 83.3 % cattle. The qualitative and quantitative tests for mutation drift equilibrium revealed absence of genetic bottleneck events in Niger cattle in the recent past. High genetic diversity and poor genetic structure among indigenous cattle breeds of Niger might be due to historic zebu–taurine admixture and ongoing breeding practices in the region. The results of the present study are expected to help in formulating effective strategies for conservation and genetic improvement of indigenous Niger cattle breeds.

    The kidnapping on 16 September 2010 of seven Areva and Satom (a subsidiary of the Vinci Group) employees, which was claimed by the Salafist brigade of Al Qaeda in the Islamic Maghreb (AQIM), thrust the Republic of Niger into the political and media spotlight. This commando-type operation at the Arlit mining site was followed four months later by a similar operation, this time in the heart of Niger's capital, Niamey. While four of the seven hostages are still being held in northern Mali (three were released in February 2011), the two young people abducted from a restaurant in Niamey were probably executed by their captors as they were pursued at the Malian border by the Niger army supported by French troops. [2] According to another version, one of the young people...[2] Among the poorest countries in the world, Niger rarely features in the headlines, except for the dramatic periods of drought which regularly affect the population, leading to solidarity campaigns, and for coups d'etat impacting the country's political life. The most recent of these coups d'etat (February 18, 2010) deposed President Mamadou Tandja who had modified the Constitution in order to remain in power (Gregoire 2010). Since then, the chain of historical events has accelerated at a rapid pace. The latest event was the election of Mahamadou Issoufou as president of the republic, after an election that took place under conditions of transparency and respect for democracy (March 12, 2011). The task facing the ninth Niger president will not be easy. Among other things, he will have to address the insecurity resulting from the presence of AQIM in Mali's territory, which was 'refueled' by western hostages in Niger. He will also need to eradicate the criminal economy (trafficking of all kinds, starting with drugs) now widespread in the Sahara region, and attempt to lift the country out of underdevelopment.

    2006-07-15

    A study was carried out during 2001 on mine tailings in NW Bohemia aimed at describing the spatial patterns of nests distribution and epigeic activity of ants in relation to the vegetation mosaic. Lasius niger was the most abundant species of ant and its nest mounds were significantly more numerous in patches with sparse vegetation than inside dense Calamagrostis epigejos vegetation; this was particularly true for small and medium-sized nests. Small and medium nests also occurred more frequently near the edges of a given patch than in the center. Large and medium nests were randomly distributed in the area, whereas small nests had an aggregated distribution. Pitfall trapping reveal significantly higher activity of L. niger workers in tall and dense vegetation stands in comparison with low and sparse vegetation. This pattern was particularly pronounced during the peak of foraging activity in summer and was not so significant in spring or autumn. We expect that ants preferentially forage in shaded habitats during the summer months when bare soil may be too hot. The results indicated that nesting and foraging may differ in their microclimatic requirements and the formation of vegetation mosaics may be important to changes in the ant population during succession.

    The research work undertaken by the Atomic Energy Commission on the territory of the Republic of the Niger has led to the discovery of two major uranium deposits, Arlit and Akouta, which are situated at the of the Sahara to the West of the massif of l'Air at approximately 850 km from Niamey. These deposits are exploited by two firms according to Nigerian law with a head office at Niamey. The firm Somair acts for Arlit and operates an open pit; the mining company Akouta works the Akouta deposit which is deeper and entails an underground operation. The production capacities are 2300 t and 2000 t of uranium metal per year, respectively [fr

    There are substantial needs of the Sahelien Zone to detail the state of regional agricultural resources in the face of a sixth year of serious drought conditions. While most of the work has been done in the Republic of Niger, the principles which have emerged from the analysis seem to be applicable to much of the Sahel. The discussion relates to quite specific rehabilitation and development initiations under consideration in Niger which are based in part upon direct analysis of ERTS imagery of the country, in part on field surveys and on discussions with Nigerian officials and technicians. Again, because the entire Sahelien Zone (including Niger) has large zones of similar ecologic characteristics, modificiations of the approaches suggested for Niger are applicable to the solution of rehabilitation of the desert, the savannah and the woodlands of West Africa in general.

    Niger is a Sahelian country bordered by Algeria and Libya to the north, Mali and Burkina Faso to the west, Benin and Nigeria to the south and Chad to the east. Niger has approximately 17 million habitants in the last census (2013) and covers an area of 1.27 million km"2. Niger’s climate is very hot and dry (45-50°C in the hot season, 30°C in the winter), daily ranges of temperature vary from 20 to 30°C. There is a rainy season with light rain fall (40 mm) extending from June to September. Niger’s economy is centered on subsistence agriculture, animal husbandry and uranium production. Uranium exports accounted for 70% of the national export economy during the 1970s, but falling prices have caused the contribution from uranium to shrink substantially in recent years. Uranium ore deposits in the Niger Republic are located in the western part of the country, west of the Aïr Mountains. The Arlit site is located 250 km north of Agadez, and 1200 km north-west of Niamey, the capital of Niger. After the discovery of the first uranium occurrences in 1956, systematic exploration programmes were conducted between 1960 and 1968 along the western sedimentary margin of Aïr Mountains, in North Central Niger by French company CEA. These programmes led to the discovery of several uranium deposits including the Arlit and Akouta deposits which are presently being mined respectively by SOMAIR and Cominak. Further works by CEA and its 100% subsidiary COGEMA and other companies consisted basically in follow up of the different targets outlined by the above programmes. The rocks hosting the uranium mineralisation are commonly arenites of the Carboniferous age Guezouman and Tarat Formations. Some beds within the Tchirozerine Formation of Jurassic age and the Irhazer Formation of Cretaceous age also contain uranium. The depositional environment of these formations was fluvial to deltaic. Apparently uranium was leached from the basement. Tectonic, lithological and geochemical

    In Niger Republic, uranium exploitation has begun since 1970. It is an economic resource but also causes social and environmental problems. To exploit according to the rule, to protect social environment, to work in safe conditions and contribute to the development of local population one side and Niger Republic in the other side, a mining law was voted in March 1993. It is about the ordinance n°93-16 on mining law which was modified in August 2006 by a new mining law, the ordinance n°2006-26 of 9 August 2006. As well as the presidential decree affecting the application of this new law was issued. Other legislative and regulatory texts have been taken as far as exploration and exploitation mining. For example, the mining agreement, the order n°0073/PM of 4 July 2005 relative to the transparency on mining exploitation; ordinance n°97-001 of 10 January 1997 appointing the environmental studying impact and the law 98–56 of 29 December 1998 relative to the management of environment. For acquisition of an exploration licence or a mining licence, a mining agreement is signed between the mining company and Niger Republic which makes clear social, environmental, financial, and economic conditions in which the mining company must exploit natural resources. The ordinance n°93-16 of 2 March 1993 related to the mining law in chapter IV, clarifies conditions for acquisition of exploration and mining licence in Niger Republic. It clarifies again in the same chapter, title VI, rights and obligations relating to mine or quarry operations for companies and tax provisions relative those activities. In the same order, in title VIII, hygiene and security conditions in mines are been specified. The mining agreement in title IV, specify rights, obligations and administration in mining activities, particularly article 18.2 which stipulates “the mining company undertakes to contribute to the development of municipalities in which it shall carry out activities, by contributing to

    Full Text Available Stemming is a main step used to process textual data. It is usually used in several types of applications such as: text mining, information retrieval (IR, and natural language processing (NLP. A major task in stemming is to standardize words; which can be achieved by reducing each word to its base (root or stem. Arabic stemming is not an easy task. Unlike other languages, Arabic language is a highly inflected language, since it uses many inflectional forms. Researchers are divided on the benefit of using stemming in fields of IR, NLP...etc., since in Arabic the morphological variants of a certain word are not always semantically related. The aim of this paper is to design and implement a new Arabic light stemmer (ARS which is not based on Arabic root patterns. Instead, it depends on well defined mathematical rules and several relations between letters. A series of tests were conducted on ARS stemmer to compare its effectiveness with the effectiveness of two other Arabic stemmers. Test shows clearly the effectiveness superiority of ARS compared to effectiveness of these two Arabic stemmers.

    2011-01-01

    Mycelial fungi use hyphae to colonize substrates. These hyphae secrete enzymes that convert complex polymers into breakdown products that can be taken up to serve as nutrients. Using GFP as a reporter it has been shown that exploring hyphae of Aspergillus niger are heterogenic with respect to expression of the glucoamylase gene glaA; some hyphae strongly express the glucoamylase gene glaA, while others express it lowly. This was a surprising finding considering the fact that all hyphae were e...

    2014-01-01

    Aspergillus niger is a black-spored filamentous fungus that forms asexual spores called conidospores (‘conidia’). Germination of conidia, leading to the formation of hyphae, is initiated by conidial swelling and mobilisation of endogenous carbon and energy stores, followed by polarisation and emergence of a hyphal germ tube. These morphological and biochemical changes which define the model of germination have been studied with the aim of understanding how conidia sense and utilise different...

Namun, pada kaedah penulisan Arab Melayu Riau saat ini, semua kosa-kata ditulis sesuai dengan konsonannya tanpa membedakan antara kosa-kata yang berasal dari bahasa Arab atau bukan bahasa Arab. Implikasi dari pergeseran kaedah penulisan ini, banyak kosa kata yang diadobsi dari bahasa Arab berbeda penulisannya dari bentuk asalnya. Perbedaan penulisan yang kontras ini menyebabkan banyak peserta didik, baik di tingkat sekolah menengah maupun perguruan tinggi salah dalam menulis nama sendiri, nama pahlawan, nama jalan, nama instansi, yayasan, dan kosa kata lainnya yang berasal dari bahasa Arab. Akibat dari kesalahan tersebut tidak hanya sekedar salah dilihat dari segi kaedah, bahkan juga dapat merubah makna kata dari makna asalnya dalam bahasa Arab. Jika hal ini tidak dikaji ulang, maka misi penulisan Arab Melayu tidak lagi untuk mendekatkan penggunanya agar mudah mempelajari bahasa Arab, akan tetapi keberadaannya akan mengganggu kesuksesan pengajaran bahasa Arab di bumi Lancang Kuning

    Aspergillus niger, as an important industrial fermentation strain, is widely applied in the production of organic acids and industrial enzymes. With the development of diverse omics technologies, the data of genome, transcriptome, proteome and metabolome of A. niger are increasing continuously, which declared the coming era of big data for the research in fermentation process of A. niger. The data analysis from single omics and the comparison of multi-omics, to the integrations of multi-omics based on the genome-scale metabolic network model largely extends the intensive and systematic understanding of the efficient production mechanism of A. niger. It also provides possibilities for the reasonable global optimization of strain performance by genetic modification and process regulation. We reviewed and summarized progress in omics research of A. niger, and proposed the development direction of omics research on this cell factory.

  7. Arab Media Discourse: Breaking Taboos

    Directory of Open Access Journals (Sweden)

    El Mustapha Lahlali

    2016-01-01

    Full Text Available This paper examines the development and change of Arab media discourse since mid-1990s. The paper looks at how the production and consumption of media discourse have changed dramatically in the Arab world over the last decade or so, notably in relation to taboos such as religion, governance and gender. The paper argues that transnational Arab media, particularly al-Jazeera, have contributed to this change by adopting a liberal and critical approach when dealing with Arab taboos. This change is clearly reflected in the new discourse adopted by both the Arab public and Arab media. Such a discourse practice shapes and is shaped by a new Arab social, cultural and political practice.

  8. The Niger Delta Amnesty Program

    2016-06-01

    Full Text Available The armed conflict between militias and government forces in Nigeria’s Niger Delta region has spanned for more than two decades, defying all solutions. A disarmament, demobilization, and reintegration (DDR program was established in August 2015 in effort to end the violence and has remained in place. It is a radically different approach from past approaches that displayed zero tolerance to all political challenges to oil production or the allocation of oil profits. The approach appeared to be immediately successful in that it forced a ceasefire, engaged militants in planned programs to rehabilitate and reintegrate them into civilian society, and opened up the oil wells (many of which had been shut due to the crisis with the effect of increasing government revenue, which depends 85% on oil exports. Yet, few studies have attempted to understand the dynamics within the country that are responsible for the design and implementation of this broad policy shift or to understand whether and how the current initiative is able to end the conflict and institute peace beyond the short term. This study, therefore, is important because it provides a critical perspective that anticipates and explains emerging issues with the Niger Delta Amnesty Program, which have implications for DDR adaptation and implementation all over the world. Ultimately, the research demonstrates how the DDR program both transforms the Niger Delta conflict and becomes embroiled in intense contestations not only about the mechanism for transforming the targeted population but also whether and how the program incorporates women who are being deprioritized by the program.

    The FMPP is a fuel plates manufacturing plant for test reactors. This facility was designed, constructed in El Cairo and turned-key handled by INVAP SE to the Arabian Republic of Egypt. In this project, CNEA participated in the transference of technology, elaboration of documents, training of Egyptian personnel and technical services during the setup of the facility in El Cairo. These tasks were undertaken by UPMP (Uranium Powder Manufacturing Plant) and ECRI (Research Reactors Fuel Elements Plant) personnel. Both plants in CNEA served as a FMPP design basis. During the setup of the facility a fuel element with natural uranium was firstly manufactured and then another one using uranium with 20% enrichment. In this paper the responses of the system regarding safety, after finishing the first two stages of manufacturing, are analyzed and evaluated. (author)

    1985-02-01

    This discussion of the United Arab Emirates focuses on the following: the people; geography; history; government; political conditions; defense; the economy; foreign relations; and relations between the US and the United Arab Emirates. In 1983 the population was estimated at 1,194,000. In 1984 the annual growth rate was negative. Life expectancy is about 60 years. Fewer than 20% of the population are UAE citizens. Indigenous Emiris are Arab; the rest of the population includes significant numbers of other Arabs -- Palestinians, Egyptians, Jordanians, Yemenis, Omanis, as well as many Iranians, Pakistanis, Indians, and West Europeans, especially in Dubai. The UAE is in the eastern Arabian Peninsula, bounded on the north by the Persian Gulf. European and Arab pirates roamed the Trucial Coast area from the 17th century into the 19th century. Early British expeditions against the pirates led to further campaigns against their headquarters. Piracy continued intermittently until 1835, when the shaikhs agreed not to engage in hostilities at sea. Primarily in reaction to the ambitions of other European countries, the UK and the Trucial States established closer bonds in an 1892 treaty. In 1968 the British government announced its decision, reaffirmed in March 1971, to end the treaty relationship with the gulf shaikhdoms. When the British protective treaty with the Trucial Shaikhdoms ended on December 1, they became fully independent. On December 2, 1971, 6 of them entered into a union called the United Arab Emirates. The 7th, Ras al-Khaimah, joined in early 1972. Administratively, the UAE is a loose federation of 7 emirates, each with its own ruler. The pace at which local government in each emirate is evolving, from traditional to modern, is set primarily by the ruler. Under the provisional constitution of 1971, each emirate reserves considerable powers, including control over mineral rights, taxation, and police powers. In this milieu, the growth of federal powers has

    Full Text Available Twitter, an online micro blogs, enables its users to write and read text-based posts known as “tweets”. It became one of the most commonly used social networks. However, an important problem arises is that the returned tweets, when searching for a topic phrase, are only sorted by recency not relevancy. This makes the user to manually read through the tweets in order to understand what are primarily saying about the particular topic. Some strategies were developed for summarizing English micro blogs but Arabic micro blogs summarization is still an active research area. This paper presents a machine learning based solution for summarizing Arabic micro blogging posts and more specifically Egyptian dialect summarization. The goal is to produce short summary for Arabic tweets related to a specific topic in less time and effort. The proposed strategy is evaluated and the results are compared with that obtained by the well-known multi-document summarization algorithms including; SumBasic, TF-IDF, PageRank, MEAD, and human summaries.

    Full Text Available The essay studies the contribution of Moriscos to Arabic studies. It concludes that the contributions of Moriscos in the Iberian peninsula remained modest. Some contributed actively to the knowledge of Arabic through their Arabic-Islamic learning. I show that the Mudejar convert known as Juan Andrés, who wrote one of the most influential treatises against Islam, was indeed a canon of the cathedral of Granada. I briefly discuss the contribution of Moriscos to the translations and interpretations of the Lead Books and studied their post-expulssion contribution to Arabic and Islamic studies. The last part focuses on the Dutch Republic, where, as a result of historical circumstances and contingent factors such as personal relations, Moriscos played an important role. Here, in addition to the study of the Arabic language itself, the physical sciences played a noteworthy role. This, I suggest, can be connected to the broad scope of the emergence of Arabic studies in Europe, which incorporated both the physical sciences and religion and philosophy, and an interest in North Africa itself because of developments in the physical sciences, including their application in daily life.

    2015-12-01

    Virginity is part of our existence in the world as embodied sexual subjects. While many meanings are associated with virginity, in most of the Arab world virginity relates to the presence of a hymen and extends to encompass the honor of the Arab community, and virginity loss commonly relate to first vaginal intercourse. This study explored the meanings of virginity from the perspectives of Arab and Arab American women. A qualitative phenomenological approach, informed by the philosophy of Maurice Merleau-Ponty, was used to conduct in-depth interviews with ten women. We identified one over-arching theme Virginity as Identity , and two major themes Embodiment of Virginity and "We are Arabs." To reach an embodied virginity, participants went through a disembodied virginity process, reflecting society's perceptions and values of virginity related to anatomical presence of a hymen and society's honor. "We are Arabs" describes the ways women identified with the Arab ethnic identity as a shared overall identification, but differed from one lived experience to another, and influenced how participants embodied virginity. Our participants provided a better understanding of the diverse meanings of virginity that move beyond the binary of virginity and virginity loss, and into a spectrum of embodied meanings. Findings suggest the need for future research around sexuality in Arab Americans with attention to socio-political contexts in order to understand the nature and context of sexual initiation and its impact on sexual behaviors and well-being.

    2012-01-01

    Novel Techniques for Dialectal Arabic Speech describes approaches to improve automatic speech recognition for dialectal Arabic. Since speech resources for dialectal Arabic speech recognition are very sparse, the authors describe how existing Modern Standard Arabic (MSA) speech data can be applied to dialectal Arabic speech recognition, while assuming that MSA is always a second language for all Arabic speakers. In this book, Egyptian Colloquial Arabic (ECA) has been chosen as a typical Arabic dialect. ECA is the first ranked Arabic dialect in terms of number of speakers, and a high quality ECA speech corpus with accurate phonetic transcription has been collected. MSA acoustic models were trained using news broadcast speech. In order to cross-lingually use MSA in dialectal Arabic speech recognition, the authors have normalized the phoneme sets for MSA and ECA. After this normalization, they have applied state-of-the-art acoustic model adaptation techniques like Maximum Likelihood Linear Regression (MLLR) and M...

    Full Text Available To promote Arabic teaching, researchers examined attitudes and expectations of parents regarding the importance of their children's Arabic study. In four states Researchers surveyed 238 Arabic-speaking and 128 non-Arabic speaking parents of children at urban and suburban schools offering Arabic as part of their mainstream programs. Most parents demonstrated positive attitudes toward language learning. They involved and encouraged their children's Arabic study and involved themselves in it. Arabic-speaking parents believed Arabic important for their children to maintain communication and affinity with family; preserve culture, religion, and traditions; maintain cultural heritage in the United States; and maintain moral and professional values. Non-Arabic speaking parents expressed similar reasons. However, Arabic-speaking parents recognized a wider variety of benefits to learning Arabic. Researchers concluded that parental attitudes toward language learning have great impact on children's learning process, but noted a discrepancy between the attitudes and expectations of Arabic- versus non-Arabic-speaking parents regarding learning Arabic.

    This review explains the situation of petroleum products and gas in Arab countries. Several kinds of difficulties are exposed: too many projects, concurrence of other producers like Australia, Indonesia, Malaysia, Norway, Russian Federation, will be rude. New exporters (Iran, Venezuela, Nigeria, even Alaska) will appear and will want a part of market and western countries will probably diversify their tradesmen. An other point is that producers overestimate future growth of worldwide demand or underestimate the impact of more expansive gas price on this demand. Inversely if this one is too low, several projects, would not be profitable. The last point is in the concurrence between gas and petroleum products, which needs a consistent policy

    Under the IAEA expert's guidance, the seeds of some important field crops were irradiated with gamma rays in order to obtain beneficial mutations, especially with regard to improving the quality of the product and increasing the yield potential in addition to increasing the resistance against disease and lodging and shortening the vegetation period and plant height. The irradiation was done with a cobalt-60 unit. Once the seeds were irradiated, they were examined for the degree of germination attained. About 45 days after irradiation, the seeds were planted at an agricultural experimental field at Inshas. For cytological investigations, i.e. for a study of the radiation effects on cell tissues, the root tips of the seedlings were cut off after the germination test and were examined by a special process. Another type of experiment carried out consisted in soaking small samples of certain seeds in a solution of radioactive phosphorus (phosphorus-32) before planting them. This was intended to obtain beneficial mutations in some of the morphological and physiological characteristics of the plants. Some of the seeds were soaked for 24 hours, others for 48 hours. Later they were washed in distilled water and planted at the Inshas experimental field

    Many cells and organisms go through polarized growth phases during their life. Cell polarization is achieved by local accumulation of signaling molecules which guide the cytoskeleton and vesicular trafficking to specific parts of the cell and thus ensure polarity establishment and maintenance. Polarization of signaling molecules is also fundamental for the lifestyle of filamentous fungi such as Aspergillus niger and essential for their morphogenesis, development and survival under environmental stress conditions. Considerable advances in our understanding on the protagonists and processes mediating polarized growth in filamentous fungi have been made over the past years. However, how the interplay of different signaling pathways is coordinated has yet to be determined. We found that the A. niger RmsA protein is central for the polarization of actin at the hyphal tip but also of vital importance for the metabolism, viability and stress resistance of A. niger. This suggests that RmsA could occupy an important position in the global network of pathways that balance growth, morphogenesis and survival of A. niger. PMID:20585521

    The Niger River Delta is a prolific hydrocarbon province and a mega-delta of economic and environmental relevance. To understand patterns of its recent shoreline evolution (1923-2013) in response to the Niger River hydrology, and establish the role played by forces of Nature and Human, available topographic and satellite remote sensing data, combined with hydro-climatic (rainfall and runoff) data were analyzed. Results indicate that the entire delta coastline dramatically receded: 82% of the >400 km-long coast retreated, during the period 1950-1987; and 69% between 2007 and 2012. Prior to 1950, there was a continuation of seaward advancement along 53-74% of the delta coast. The 1950-1987 shoreline recession coincided with occurrences of two major events in the Niger River basin; these are downward trends in hydro-climatic conditions (the great droughts of the 1970s-1980s), and dam construction on the Lower Niger River at Kainji (1964-1968). The 2007-2012 event corresponded with the extensive channel dredging during 2009-2012 in the Lower Niger River from the coastal town of Warri in the south to Baro in the north. Remarkably, the largest net shoreline advancement recorded in 74% of the entire delta area occurred within a year (2012-2013), which we link to increased sediment supply to the coast caused by the '2012' floods, adjudged the worst floods in the entire Niger River Basin in the last few decades. With both anthropogenic and environmental factors inducing delta evolution, only innovative river and coastal management can determine the fortune of the future coastal development of the Niger Delta.

    To determine the smoking behavior in pregnant Arab American women who attended a Women, Infant and Children (WIC) program at a local county public health clinic and compare the incidence of smoking behaviors of pregnant Arab American women with pregnant women who were not Arab Americans. Data were extracted from a computer database that contained information from health history charts of pregnant Arab and non-Arab American women. The study sample was 830 women, 823 of whom were Arab American participants enrolled in the WIC program in Michigan. Approximately 6% of pregnant Arab Americans smoked during pregnancy. The prevalence of smoking behavior among pregnant Arab American women was similar to that of smoking behaviors of Hispanics and Asian Americans in the United States. Although smoking behavior is a serious problem among Arab American immigrants in general and in the Arab world in particular, cultural factors that support healthy behavior during pregnancy in the Arab culture seem to limit the use of tobacco in pregnant women. Nurses who care for Arab American pregnant women can use this information to better inform their care of these patients.

    2006-09-01

    Aspergillus niger is a filamentous ascomycete fungus that is ubiquitous in the environment and has been implicated in opportunistic infections of humans. In addition to its role as an opportunistic human pathogen, A. niger is economically important as a fermentation organism used for the production of citric acid. Industrial citric acid production by A. niger represents one of the most efficient, highest yield bioprocesses in use currently by industry. The genome size of A. niger is estimated to be between 35.5 and 38.5 megabases (Mb) divided among eight chromosomes/linkage groups that vary in size from 3.5 - 6.6 Mb. Currently, there are three independent A. niger genome projects, an indication of the economic importance of this organism. The rich amount of data resulting from these multiple A. niger genome sequences will be used for basic and applied research programs applicable to fermentation process development, morphology and pathogenicity.

    1986-01-01

    This paper considers interactions of uranium with the microfilamentous fungus Aspergillus niger grown as pellets 4 mm in diameter for column application. Adsorption and desorption isotherms, a range of physical measurements, and a derived mechanistic model, indicated that a simple ion exchange process predominates in which uranyl cations reversibly replace protons on the amino acid groups of proteins and glycoproteins within the cell wall structure. Under the conditions employed uranium adsorbed onto A. niger (CMI 296409) some fourteen times more efficiently at pH 4 than onto the ion exchange resin IRA-400, and was readily desorbed at pH 1. The fungus had inferior selectivity and wet volume/dry weight ratio. Uranium was adsorbed semi-continuously by heat-killed A. niger pellets fluidised in a compartmentalised column. When operated with an intermittent countercurrent flow of the biomass, uranium concentrations of 100 g/m 3 and 5 g/m 3 at pH 4 could be reduced to less than 10 g/m 3 and 1 g/m 3 , respectively.

  2. Polycistronic gene expression in Aspergillus niger.

    Science.gov (United States)

    Schuetze, Tabea; Meyer, Vera

    2017-09-25

    Genome mining approaches predict dozens of biosynthetic gene clusters in each of the filamentous fungal genomes sequenced so far. However, the majority of these gene clusters still remain cryptic because they are not expressed in their natural host. Simultaneous expression of all genes belonging to a biosynthetic pathway in a heterologous host is one approach to activate biosynthetic gene clusters and to screen the metabolites produced for bioactivities. Polycistronic expression of all pathway genes under control of a single and tunable promoter would be the method of choice, as this does not only simplify cloning procedures, but also offers control on timing and strength of expression. However, polycistronic gene expression is a feature not commonly found in eukaryotic host systems, such as Aspergillus niger. In this study, we tested the suitability of the viral P2A peptide for co-expression of three genes in A. niger. Two genes descend from Fusarium oxysporum and are essential to produce the secondary metabolite enniatin (esyn1, ekivR). The third gene (luc) encodes the reporter luciferase which was included to study position effects. Expression of the polycistronic gene cassette was put under control of the Tet-On system to ensure tunable gene expression in A. niger. In total, three polycistronic expression cassettes which differed in the position of luc were constructed and targeted to the pyrG locus in A. niger. This allowed direct comparison of the luciferase activity based on the position of the luciferase gene. Doxycycline-mediated induction of the Tet-On expression cassettes resulted in the production of one long polycistronic mRNA as proven by Northern analyses, and ensured comparable production of enniatin in all three strains. Notably, gene position within the polycistronic expression cassette matters, as, luciferase activity was lowest at position one and had a comparable activity at positions two and three. The P2A peptide can be used to express at

  5. Nigeria National Petroleum Reserves Asset: Looking Beyond the Niger Delta

    2002-01-01

    Nigeria's current national petroleum reserves asset (proven) put at 28 billion barrels of oil and 150 trillion standard cubic feet of gas derives mainly from the Niger Delta onshore and offshore.However, there are opportunities to tremendously add to this asset from the inland basins. These inland basins have continued to frustrate the efforts of many explorers, principally because of their virginity and far distance from existing infrastructure, and for these reasons, many international companies have turned their focus away from frontier onshore to frontier deep-water and ultra deep-water offshore.Petroleum exploration, particularly in the Sudan and Chad Republics has shown that commercial success can be achieved in our own sector, even if it may take some time to put all the elements together. Some pointers have been found from the successes in the other rifted inland basins and the strategies adopted there have been examined in this paper. Congnizance has also been taken of the relative success of Shell's Kolmani River-1 well (33 billion cubit feet of gas) in the Gongola Basin. The paper went ahead to highlight potential petroleum systems in the different sectors of Nigeria's inland basins.Recommendations have also been put forward, which include amongst others (i) the introduction of a JV arrangement that allows State Governments on the inland basins to participate in the exploration for hydrocarbons in their domains (ii) tie future allocation of offshore blocks to acquisition of at least a block in any of the inland basins (iii) initiate a programme of deep drilling and coring of at least one research well to penetrate the entire sedimentary rock successions in each of the inland basins to facilitate a better understanding of their petroleum geology and benefit future exploration campaigns; to be funded and supervised by the Petroleum Technology Development Fund (PTDF)

  9. Aspergillus niger Secretes Citrate to Increase Iron Bioavailability

    Odoni, Dorett I.; van Gaal, Merlijn P.; Schonewille, Tom; Tamayo-Ramos, Juan A.; Martins dos Santos, Vitor A. P.; Suarez-Diez, Maria; Schaap, Peter J.

    2017-01-01

    Aspergillus niger has an innate ability to secrete various organic acids, including citrate. The conditions required for A. niger citrate overproduction are well described, but the physiological reasons underlying extracellular citrate accumulation are not yet fully understood. One of the less understood culture conditions is the requirement of growth-limiting iron concentrations. While this has been attributed to iron-dependent citrate metabolizing enzymes, this straightforward relationship does not always hold true. Here, we show that an increase in citrate secretion under iron limited conditions is a physiological response consistent with a role of citrate as A. niger iron siderophore. We found that A. niger citrate secretion increases with decreasing amounts of iron added to the culture medium and, in contrast to previous findings, this response is independent of the nitrogen source. Differential transcriptomics analyses of the two A. niger mutants NW305 (gluconate non-producer) and NW186 (gluconate and oxalate non-producer) revealed up-regulation of the citrate biosynthesis gene citA under iron limited conditions compared to iron replete conditions. In addition, we show that A. niger can utilize Fe(III) citrate as iron source. Finally, we discuss our findings in the general context of the pH-dependency of A. niger organic acid production, offering an explanation, besides competition, for why A. niger organic acid production is a sequential process influenced by the external pH of the culture medium.

    Bibliometric analysis is increasingly employed as a useful tool to assess the quantity and quality of research performance. The specific goal of the current study was to evaluate the performance of research output originating from Arab world and published in international Integrative and Complementary Medicine (ICM) journals. Original scientific publications and reviews from the 22 Arab countries that were published in 22 international peer-reviewed ICM journals during all previous years up to December 31(st) 2013, were screened using the Web of Science databases. Five hundred and ninety-one documents were retrieved from 19 ICM journals. The h-index of the set of papers under study was 47. The highest h-index was 27 for Morocco, 21 for Jordan, followed by 19 for each Kingdom of Saudi Arabia (KSA), and Egypt, and the lowest h-index was 1 for each of Comoros, Qatar, and Syrian Arab Republic. No data related to ICM were published from Djibouti, and Mauritania. After adjusting for economy and population power, Somalia (89), Morocco (32.5), Egypt (31.1), Yemen (21.4), and Palestine (21.2) had the highest research productivity. The total number of citations was 9,466, with an average citation of 16 per document. The study identified 262 (44.3 %) documents with 39 countries in Arab-foreign country collaborations. Arab authors collaborated most with countries in Europe (24.2 %), followed by countries in the Asia-Pacific region (9.8 %). Scientific research output in the ICM field in the Arab world region is increasing. Most of publications from Arab world in ICM filed were driven by societal use of medicinal plants and herbs. Search for new therapies from available low cost medicinal plants in Arab world has motivated many researchers in academia and pharmaceutical industry. Further investigation is required to support these findings in a wider journal as well as to improve research output in the field of ICM from Arab world region by investing in more national and

    Full Text Available In this paper, an Arabic statistical learning-based text classification system has been developed using Polynomial Neural Networks. Polynomial Networks have been recently applied to English text classification, but they were never used for Arabic text classification. In this research, we investigate the performance of Polynomial Networks in classifying Arabic texts. Experiments are conducted on a widely used Arabic dataset in text classification: Al-Jazeera News dataset. We chose this dataset to enable direct comparisons of the performance of Polynomial Networks classifier versus other well-known classifiers on this dataset in the literature of Arabic text classification. Results of experiments show that Polynomial Networks classifier is a competitive algorithm to the state-of-the-art ones in the field of Arabic text classification.

    1969-01-01

    In this study, retting was carried out by Aspergillus niger. The pH, galacturonic acid (GA), and total reducing sugar were determined; the end point was identified by the classic empirical processes and by the maximal GA content of the retting water. The process gave clear and resistent fibers, and the retting time was similar to that of current industrial processes with bacterial enzymes. Control of total acidity was not required, since the pH remained close to neutrality throughout the entire process. PMID:16349835

    An energy issue for the United States and a political challenge for Europe, Nigeria is experiencing growing instability and is on the verge of civil war; the ecosystem and the population of the Niger Delta are the main victims. The State, corrupt, is powerless to contain the rising violence and redistribute the proceeds of oil sales. It is high time for oil-consuming countries, starting with the United States, to concern themselves with stabilizing the region. Europe must contribute to the lasting development of this country.

This study uses a case study on three figure writers of religious texts that using the Arabic alphabet in southern part of Central Java (Yogyakarta, namely Asrori Ahmad (Magelang, Ali Maksum (Yogyakarta, and Ahmad Mujab Mahalli (Bantul. This study concluded that the writing of religious texts in Arabic alphabet in the southern Java area had been carried out by means of using Arabic Pegon, and only a few people who wrote in the Arabic language. The transmission of Arabic Pegon in Yogyakarta is allegedly from north coast of Java, especially from Lasem / East Java. The tradition of Arabic language teaching in the pesantrens still focuses mostly on the reading effort, communication, and understanding and it is not oriented to the writing skill. The presence of international journals initiated by the College of Islamic religious institutions and the effort of translation business into Arabic from certain institutions gives an opportunity to strengthen the use of the Arabic alphabet in Indonesia.

    2015-04-01

    Full Text Available Stemming algorithms are used in information retrieval systems, indexers, text mining, text classifiers etc., to extract stems or roots of different words, so that words derived from the same stem or root are grouped together. Many stemming algorithms were built in different natural languages. Khoja stemmer is one of the known and widely used Arabic stemmers. In this paper, we introduced a new light and heavy Arabic stemmer. This new stemmer is presented in this study and compared with two well-known Arabic stemmers. Results showed that accuracy of our stemmer is slightly better than the accuracy yielded by each one of those two well-known Arabic stemmers used for evaluation and comparison. Evaluation tests on our novel stemmer yield 75.03% accuracy, while the other two Arabic stemmers yield slightly lower accuracy.

  6. Effect of simulated microgravity on Aspergillus niger

    Pratap, Jeffrey J.

    2005-08-01

    A rotating bioreactor was developed to simulate microgravity and its influence was studied on fungal growth. The reactor was designed to simulate microgravity using 'free fall' principle, which creates an apparent weightlessness for a brief period of time. In this experiment, a sealed vertically rotating tube is the reactor in which the cells are grown. For the first time vertically rotating tubes were used to obtain 'free fall' thereby simulating microgravity. Simulated microgravity served significant in the alteration of growth and productivity of Aspergillus niger, a common soil fungi. Two other sets of similar cultures were maintained as still and shake control cultures to compare with the growth and productivity of cells in rotating culture. It was found increased growth and productivity occurred in simulated microgravity. Since this experiment involves growth of cells in a liquid medium, the fluidic effects must also be studied which is a limitation.

    Keni, Sarita; Punekar, Narayan S

    2016-02-01

    Aspects of manganese metabolism during normal and acidogenic growth of Aspergillus niger were explored. Arginase from this fungus was a Mn[II]-enzyme. The contribution of the arginase protein towards A. niger manganese metabolism was investigated using arginase knockout (D-42) and arginase over-expressing (ΔXCA-29) strains of A. niger NCIM 565. The Mn[II] contents of various mycelial fractions were found in the order: D-42 strain niger mycelia harvested from acidogenic growth media contain substantially less Mn[II] as compared to those from normal growth media. Nevertheless, acidogenic mycelia harbor considerable Mn[II] levels and a functional arginase. Altered levels of mycelial arginase protein did not significantly influence citric acid production. The relevance of arginase to cellular Mn[II] pool and homeostasis was evaluated and the results suggest that arginase regulation could occur via manganese availability.

  14. Fumonisins in Aspergillus niger: Industrial and food aspects

    DEFF Research Database (Denmark)

    Frisvad, Jens Christian; Nielsen, Kristian Fog; Mogensen, Jesper

    Introduction: Fumonisins are toxic seconday metabolites from Fusarium verticillioides and other Fusaria, from Tolypocladium and Aspergillus niger 1,2. Being a generalist Aspergillus niger is the workhorse in a very large number of industrial applications, and is also a common contaminant in foods....... Fumonisin production by A. niger is depending on temperature and water activity, but is produced mostly on substrates with high maounts of sugar or salt 1,3,4. We wanted to find out whether industrial strains could produce fumonisins in worst case scenarios and if fumonisin production was only a feature...... ever used in biotechnology could produce fuminisins B2, B4 & B6. The strains could be subdivided into two clades (representing A. niger and the “phylospecies” A. awamori), and there were fumonisin producers in both clades. Ochratoxin A was also produced by strains in both clades, but only...

    Bhalerao, Tejomyee S

    2013-11-28

    Endosulfan is a chlorinated pesticide; its persistence in the environment and toxic effects on biota are demanding its removal. This study aims at improving the tolerance of the previously isolated fungus Aspergillus niger (A. niger) ARIFCC 1053 to endosulfan. Released chloride, dehalogenase activity, and released proteins were estimated along with analysis of endosulfan degradation and pathway identification. The culture could tolerate 1,000 mg/ml of technical grade endosulfan. Complete disappearance of endosulfan was seen after 168 h of incubation. The degradation study could easily be correlated with increase in released chlorides, dehalogenase activity and protein released. Comparative infrared spectral analysis suggested that the molecule of endosulfan was degraded efficiently by A. niger ARIFCC 1053. Obtained mass ion values by GC-MS suggested a hypothetical pathway during endosulfan degradation by A. niger ARIFCC 1053. All these results provide a basis for the development of bioremediation strategies to remediate the pollutant under study in the environment.

  19. Islam and the Arabs in the work of a Maronite scholar in the service of the Catholic church (Abraham Ecchellensis

    Directory of Open Access Journals (Sweden)

    Heyberger, Bernard

    2010-12-01

    Full Text Available As an expert in Arabic documents in the “Republic of Letters”, Abraham Ecchellensis devoted himself in his work to an attempt at synthesis that was characteristic of his time: he tried to reconcile contemporary scholars’ expectations of specialised knowledge both with his Catholic and controversialist commitments and with his status, in his role as a Maronite, as a spokesman for Arabic and even Muslim culture. Ecchellensis provided the public with translations of Arabic Muslim philosophical and scientific texts which he deemed to have drawn on universal “wisdom”. However, a disinterested curiosity concerning Islam could not be publicly advertised and had to be cloaked in the form of anti-Protestant controversy or Catholic apology. In the work of Ecchellensis this stance was accompanied by an expurgation of all Islamic terminology from the Arabic language and by a recourse to the Christian Arabic literature writen during the first centuries of the Hijra.

    [fr] Expert en documents arabes dans la « République des Lettres », Abraham Ecchellensis se livre dans son oeuvre à un essai de synthèse caractéristique de son temps : il tente de concillier l’attente de connaissances des savants de son temps avec son engagement catholique et controversiste, et avec son identification, en tant que maronite, comme porte-parole de la culture arabe, y compris musulmane. Il fournit au public des traductions de textes philosophiques et scientifiques arabes musulmans qui lui paraissent participer d’une « sagesse » universelle. Mais une curiosité désintéressée pour l’islam ne peut s’afficher : elle doit prendre les formes de la controverse anti-protestante ou de l’apologie catholique. Chez Ecchellensis cette posture s’accompagne d’une expurgation de toute terminologie islamique dans la langue arabe, et d’un recours à la littérature arabe chrétienne élaboré aux premiers siècles de l’Hégire.

    Full Text Available Arab-American (AA populations in the US are exposed to discrimination and acculturative stress-two factors that have been associated with higher suicide risk. However, prior work suggests that socially oriented norms and behaviors, which characterize recent immigrant ethnic groups, may be protective against suicide risk. Here we explored suicide rates and their determinants among AAs in Michigan, the state with the largest proportion of AAs in the US.ICD-9/10 underlying cause of death codes were used to identify suicide deaths from among all deaths in Michigan between 1990 and 2007. Data from the 2000 U.S. Census were collected for population denominators. Age-adjusted suicide rates among AAs and non-ethnic whites were calculated by gender using the direct method of standardization. We also stratified by residence inside or outside of Wayne County (WC, the county with the largest AA population in the state. Suicide rates were 25.10 per 100,000 per year among men and 6.40 per 100,000 per year among women in Michigan from 1990 to 2007. AA men had a 51% lower suicide rate and AA women had a 33% lower rate than non-ethnic white men and women, respectively. The suicide rate among AA men in WC was 29% lower than in all other counties, while the rate among AA women in WC was 20% lower than in all other counties. Among non-ethnic whites, the suicide rate in WC was higher compared to all other counties among both men (12% and women (16%.Suicide rates were higher among non-ethnic white men and women compared to AA men and women in both contexts. Arab ethnicity may protect against suicide in both sexes, but more so among men. Additionally, ethnic density may protect against suicide among Arab-Americans.

Among non-ethnic whites, the suicide rate in WC was higher compared to all other counties among both men (12%) and women (16%). Suicide rates were higher among non-ethnic white men and women compared to AA men and women in both contexts. Arab ethnicity may protect against suicide in both sexes, but more so among men. Additionally, ethnic density may protect against suicide among Arab-Americans.

    2001-01-01

    Full text: Niger (Guizotia abyssinica Cass.), an important oilseed crop of the family Compositae is highly cross-pollinated due to the twin mechanisms of protandry and incompatibility. Studies revealed the functional nature of protandry and the breakdown of incompatibility with alteration in temperature. It has very small flowers (disc florets) arranged in a capitulum that open on 3-4 consecutive days which pose problems in emasculation for cross-breeding. To induce mutations, seeds of variety 'IGP-76' were irradiated with γ-rays 200 to 1000 Gy. All seeds of M 1 plants were sown separately in individual plant-to progeny rows. The results of screening of M 2 segregating material indicated that γ-ray treatment was effective in induction of male sterility. Frequency of visible mutations were higher in sibbed progeny as compared to open pollinated population and male sterile plants were observed only in sibbed population (1000 Gy). Male sterile plants could easily be identified at the flowering stage by their altered floral morphology (disc florets transformed into ligulate ray florets) and complete absence or presence of a rudimentary anther column. Seeds were collected following sib-mating with the fertile counterparts. Progeny segregated in a ration of 3 normal : 1 male sterile. Further work on the mechanism of sterility, maintenance and linkage relationships with associated characters is under progress. This is the first report of induction of male sterility in niger through the use of physical mutagens. The availability of this mutant will be of great value for exploitation of heterosis on commercial basis. (author)

    Science.gov (United States)

    2011-01-01

    Single cell profiling was performed to assess differences in RNA accumulation in neighboring hyphae of the fungus Aspergillus niger. A protocol was developed to isolate and amplify RNA from single hyphae or parts thereof. Microarray analysis resulted in a present call for 4 to 7% of the A. niger genes, of which 12% showed heterogeneous RNA levels. These genes belonged to a wide range of gene categories. PMID:21816052

    The aim of this work was to select strains of Aspergillus niger for tannase production. Growth of colonies in plates with tannic acid-containing medium indicated their ability to synthesize tannase. Tannase activity was also measured in solid-state fermentation. A. niger 11T25A5 was the best tannase producer (67.5 U.g-1/72 hours of fermentation).

  7. The identity and witness of Arab pre-Islamic Arab Christianity: The Arabic language and the Bible

    Directory of Open Access Journals (Sweden)

    David D. Grafton

    2014-10-01

    Full Text Available This article argues that Arab Christianity has had a unique place in the history of World Christianity. Rooted in a biblical witness, the origins and history of Arab Christianity have been largely forgotten or ignored. This is not primarily as a result of the fact that the Arab Christian historical legacy has been overcome by Islam. Rather, unlike other early Christian communities, the Bible was never translated into the vernacular of the Arabs. By the 7th century the language of the Qur’an became the primary standard of the Arabic language, which then became the written religious text of the Arabs. This article will explore the identity and witness of the Christian presence in Arabia and claims that the development of an Arabic Bible provides a unique counter-example to what most missiologists have assumed as the basis for the spread of the Christian faith as a result of the translation of the Christian scriptures into a vernacular.

  8. Arab Youth: A Contained Youth?

    Directory of Open Access Journals (Sweden)

    Joerg Gertel

    2017-12-01

    Full Text Available Young people in the Arab world increasingly have to struggle with economic hardship and difficulties to start their own lives, although the majority is better educated than ever before. The problematic labor market situation combined with weak public schemes to support young careers force large sections of young people to postpone their ambitions to marry. This period of delayed marriage is captured as 'waithood'. I will argue that this term is misleading. Two points of critique apply: The social dimension of waiting exceeds the status of remaining inactive until something expected happens; the ever-changing present continuously generates new realities. Simultaneously uncertainties and insecurities have dramatically expanded since 2011 and further limit livelihood opportunities and future perspectives, particularly of the youth. Young people are hence becoming both, increasingly frustrated and disadvantaged the longer they "wait", and even more dependent on parents and kin networks. This hinders them to develop their personality – they rather have to accommodate with values that are not always suitable to master the present requirements of a globalizing world. In this paper I will inquire, in how far young people of the Arab world have thus to be considered as a “contained youth”.

  9. Preference for Democracy in the Arab World

    2016-12-01

    Full Text Available We take a new look at the question of the Arab democratic exception by looking at the preference for democracy among individuals in the Arab world in a comparative context. We use the new sixth wave of the World Value Survey, which was collected between 2012 and 2013, and which included for the first time 12 Arab countries (up from only four in wave 5 and 68 non-Arab countries. We innovate empirically by measuring the preference for democracy over strong rule in a way that, we argue, is more adapted to an understanding of the Arab world than other measures used in past studies. Our statistical analysis reveals a democratic gap in the Arab region compared to global experience, which is especially marked among the more educated individuals, and to a lesser extent among the youth and the middle class. We conclude by discussing the reasons that may explain the Arab exceptionalism, and argue that it is unlikely to be related to culture alone.

    2012-04-01

    The objectives of this study were to: (1) calculate age-specific and age-adjusted cause-specific mortality rates for Arab Americans; and (2) compare these rates with those for blacks and whites. Mortality rates were estimated using Michigan death certificate data, an Arab surname and first name list, and 2000 U.S. Census data. Age-specific rates, age-adjusted all-cause and cause-specific rates were calculated. Arab Americans (75+) had higher mortality rates than whites and blacks. Among men, all-cause and cause-specific mortality rates for Arab Americans were in the range of whites and blacks. However, Arab American men had lower mortality rates from cancer and chronic lower respiratory disease compared to both whites and blacks. Among women, Arab Americans had lower mortality rates from heart disease, cancer, stroke, and diabetes than whites and blacks. Arab Americans are growing in number. Future study should focus on designing rigorous separate analyses for this population.

    2017-12-01

    Full Text Available This article offers a critical analysis of the Arab Human Development Report (AHDR 2016, that was released by the United Nations Development Programme in November 2016. AHDR 2016 represents the return of the Arab Human Development project, that had been interrupted by the Arab Spring uprisings of 2011. It also epitomizes the Arab youth paradigm that has increasingly come to frame development and security discourse in the region. While there is much that is familiar in AHDR 2016, there are also concerning developments: a historical revisionism that holds Arab youth responsible for the Arab Spring, and the Arab Spring responsible for the Arab Winter that followed; and a new trend that views not just Arab youth deficits as a dangerous threat to regional and global security, but Arab youth abilities and surfeits as well.

    An energy issue for the United States and a political challenge for Europe, Nigeria is experiencing growing instability and is on the verge of civil war; the ecosystem and the population of the Niger Delta are the main victims. The State, corrupt, is powerless to contain the rising violence and redistribute the proceeds of oil sales. It is high time for oil-consuming countries, starting with the United States, to concern themselves with stabilizing the region. Europe must contribute to the lasting development of this country.

    Infections due to Aspergillus species cause significant morbidity and mortality. Most are attributed to Aspergillus fumigatus, followed by Aspergillus flavus and Aspergillus terreus. Aspergillus niger is a mould that is rarely reported as a cause of pneumonia. A 72-year-old female with chronic obstructive pulmonary disease and temporal arteritis being treated with steroids long term presented with haemoptysis and pleuritic chest pain. Chest radiography revealed areas of heterogeneous consolidation with cavitation in the right upper lobe of the lung. Induced bacterial sputum cultures, and acid-fast smears and cultures were negative. Fungal sputum cultures grew A. niger. The patient clinically improved on a combination therapy of empiric antibacterials and voriconazole, followed by voriconazole monotherapy. After 4 weeks of voriconazole therapy, however, repeat chest computed tomography scanning showed a significant progression of the infection and near-complete necrosis of the right upper lobe of the lung. Serum voriconazole levels were low–normal (1.0 μg ml−1, normal range for the assay 0.5–6.0 μg ml−1). A. niger was again recovered from bronchoalveolar lavage specimens. A right upper lobectomy was performed, and lung tissue cultures grew A. niger. Furthermore, the lung histopathology showed acute and organizing pneumonia, fungal hyphae and oxalate crystallosis, confirming the diagnosis of invasive A. niger infection. A. niger, unlike A. fumigatus and A. flavus, is less commonly considered a cause of invasive aspergillosis (IA). The finding of calcium oxalate crystals in histopathology specimens is classic for A. niger infection and can be helpful in making a diagnosis even in the absence of conidia. Therapeutic drug monitoring may be useful in optimizing the treatment of IA given the wide variations in the oral bioavailability of voriconazole. PMID:20299503

  20. Historical perspectives on health. Early Arabic medicine.

    Science.gov (United States)

    Brewer, Harry

    2004-07-01

    The Arabian conquests during and after the 7th century led to a spread of Islam as well as the consequential influence of theology on health through the teachings of the Qur'an (Koran). Although traditional medicine was widely accepted and used, the character of early aggrandisement of Arabic medicine involved a facility for adapting and absorbing Graeco-Roman knowledge. The translation schools and libraries, famous in both the East and West, preserved and expanded the knowledge acquired. European academic learning owed much to the Arabs. Information came through Spain to Italy, France and, later on, England. The founding of hospitals, whilst not an Arab initiative, received a fillip from the religious prescriptions for care of the sick. The Military Orders developed specialist institutions for the sick, probably as a result of what they saw during their sojourn in the Middle East. The legacy of Arabic medical care is still with us today and deserves understanding and greater appreciation.

    Distinct functional pathways for processing words and numbers have been hypothesized from the observation of dissociated impairments of these categories in brain-damaged patients. We aimed to identify the cortical areas involved in Arabic number reading process in patients operated on for various brain lesions. Direct cortical electrostimulation was prospectively used in 60 brain mappings. We used object naming and two reading tasks: alphabetic script (sentences and number words) and Arabic number reading. Cortical areas involved in Arabic number reading were identified according to location, type of interference, and distinctness from areas associated with other language tasks. Arabic number reading was sustained by small cortical areas, often extremely well localized (area (Brodmann area 45), the anterior part of the dominant supramarginal gyrus (Brodmann area 40; p area (Brodmann area 37; p areas.

    In the framework of the developments taking place in nuclear sciences and technologies during the twentieth century and the resulting increase of useful applications of these technologies, the international efforts aiming at helping different countries to establish nuclear safety systems. This was also increased through the promulgation of legislations that render the practices, which could be accompanied with exposure to ionizing radiations, more safe within a firm legal system that is also backed by promulgating suitable executive regulations. Most Arab countries are keen to promulgate their legislations for regulating the work with ionizing radiations and protection against their dangers. Those legislations usually get their genesis and provisions from the international recommendations as well as from the general legal system of the country. The present work consists of four chapters. The first chapter deals with the definition of legislations for regulating the work with ionizing radiations. Chapter two discusses the international trend to promulgate legislations for protection against ionizing radiations. Chapter three includes an analytical comparative study on the legislations that regulates the work with ionizing radiations in the Arab countries. Finally, chapter four deals with the legislations for protection against ionizing radiations in the Arab Republic of Egypt

  7. Nutritional characteristics of forages from Niger

    F. Infascelli

    2010-04-01

    Full Text Available In the production systems of the semi-arid areas low quality forages are commonly used as the basal diet (Wilkins, 2000 and, as a consequence, the nutritional status of ruminants depends mainly on the ability of rumen fermentation to yield nutrients such as the short chain fatty acids and microbial biomass (Preston and Leng, 1987. The forages browsed by the livestock can be classified into two main groups: ephemeral annual plants, which germinate and remain green for only a few weeks after rain, perennial shrubs and tree fodders. Despite their potential as feeds, little research has determined their nutritive value. In vivo evaluation is the best estimation method of feed’s nutritional value, however it is very laborious and difficult to standardize with browsing animals. O the contrary, in vitro methods are less expensive, less time consuming and allow a better control of experimental conditions than in vivo experiments. The in vitro gas production technique (IVGPT appears to be the most suitable method for use in developing countries where resources may be limited (Makkar, 2004. Increased interest in use of non-conventional feed resources has led to an increase in use of this technique, since IVGPT can provide useful data on digestion kinetics of both the soluble and insoluble fractions of feedstuffs. The aim of the present research was to evaluate twelve forages from the arid zone of Niger using the IVGPT.

    This study is the first in a series of investigations designed to test the acoustic characteristics of the normal Arabic voice. The subjects were three hundred normal Jordanian Arabic speakers (100 adult males, 100 adult females, and 100 children). The subjects produced a sustained phonation of the vowel /a:/ and stated their complete names (i.e. first, second, third and surname) using a carrier phrase. The samples were analyzed using the Multi Dimensional Voice Program (MDVP). Fundamental frequency (F0) from the /a:/ and speaking fundamental frequency (SF0) from the sentence were analyzed. Results revealed a significant difference of both F0 and SF0 values among adult Jordanian Arabic-speaking males (F0=131.34Hz +/- 18.65, SF0=137.45 +/- 18.93), females (F0=231.13Hz +/- 20.86, SF0=230.84 +/- 16.50) and children (F0=270.93Hz +/- 20.01, SF0=278.04 +/- 32.07). Comparison with other ethnicities indicated that F0 values of adult Jordanian Arabic-speaking males and females are generally consistent with adult Caucasian and African-American values. However, for Jordanian Arabic-speaking children, a higher trend in F0 values was present than their Western counterparts. SF0 values for adult Jordanian Arabic-speaking males are generally consistent with the adult Caucasian male SF0 values. However, SF0 values of adult Jordanian-speaking females and children were relatively higher than the reported Western values. It is recommended that speech-language pathologists in Arabic-speaking countries, Jordan in specific, utilize the new data provided (F0 and SF0) when evaluating and/or treating Arabic-speaking patients. Due to its cross-linguistic variability, SF0 emerged as a preferred measurement when conducting cross-cultural comparisons of voice features.

    Breast cancer is one of the most common types of cancers affecting women worldwide. The main objective of this study was to assess and compare research activity in breast cancer in Arab countries with non-Arab Middle Eastern countries. Publications about "breast cancer" as a research topic were retrieved using the ISI Web of Science database. Analysis was confined to original research and review articles. Research productivity was assessed by assessing number of publications and time trend of these publications, names of journals, citation analysis, top 10 active institutions as well as country contribution to breast cancer research. The quantity and quality of publications from Arab countries in addition to 3 other Middle East countries (Turkey, Iran and Israel) were assessed and compared using the h-index tool. A total of 1658 original research and review articles about "breast cancer" were published from Arab countries. Annual research productivity from Arab countries in the field of "breast cancer" was negligible but showed a significant increase in the last decade. Retrieved documents had relatively high citation parameters as measured by h-index of 61 and average citations of 17.46 per document. The highest research productivity was from Egypt with a total publication of 582 (35.10%). Cairo University with a total of 149 (8.99%) publications had the highest research productivity among institutions in Arab world. Forty four documents (2.65%) of breast cancer documents were published in Saudi Medical Journal. Arab researchers collaborated mostly with researchers from the United States of America (305; 18.40%) in breast cancer research. Compared with other non-Arab Middle Eastern countries, Arab countries had higher research productivity than some countries and lower than others, particularly Israel. The present data reveals a good contribution of some Arab countries to the field of "breast cancer" research. There is a gap between Arab countries and Israel in

    Aspergillus section Nigri is an important group of species for food and medical mycology, and biotechnology. The Aspergillus niger 'aggregate' represents its most complicated taxonomic subgroup containing eight morphologically indistinguishable taxa: A. niger, Aspergillus tubingensis, Aspergillus acidus, Aspergillus brasiliensis, Aspergillus costaricaensis, Aspergillus lacticoffeatus, Aspergillus piperis, and Aspergillus vadensis. Aspergillus awamori, first described by Nakazawa, has been compared taxonomically with other black aspergilli and recently it has been treated as a synonym of A. niger. Phylogenetic analyses of sequences generated from portions of three genes coding for the proteins β-tubulin (benA), calmodulin (CaM), and the translation elongation factor-1 alpha (TEF-1α) of a population of A. niger strains isolated from grapes in Europe revealed the presence of a cryptic phylogenetic species within this population, A. awamori. Morphological, physiological, ecological and chemical data overlap occurred between A. niger and the cryptic A. awamori, however the splitting of these two species was also supported by AFLP analysis of the full genome. Isolates in both phylospecies can produce the mycotoxins ochratoxin A and fumonisin B₂, and they also share the production of pyranonigrin A, tensidol B, funalenone, malformins, and naphtho-γ-pyrones. In addition, sequence analysis of four putative A. awamori strains from Japan, used in the koji industrial fermentation, revealed that none of these strains belong to the A. awamori phylospecies.

    2011-01-01

    Background Considering that the costs of cellulases and hemicellulases contribute substantially to the price of bioethanol, new studies aimed at understanding and improving cellulase efficiency and productivity are of paramount importance. Aspergillus niger has been shown to produce a wide spectrum of polysaccharide hydrolytic enzymes. To understand how to improve enzymatic cocktails that can hydrolyze pretreated sugarcane bagasse, we used a genomics approach to investigate which genes and pathways are transcriptionally modulated during growth of A. niger on steam-exploded sugarcane bagasse (SEB). Results Herein we report the main cellulase- and hemicellulase-encoding genes with increased expression during growth on SEB. We also sought to determine whether the mRNA accumulation of several SEB-induced genes encoding putative transporters is induced by xylose and dependent on glucose. We identified 18 (58% of A. niger predicted cellulases) and 21 (58% of A. niger predicted hemicellulases) cellulase- and hemicellulase-encoding genes, respectively, that were highly expressed during growth on SEB. Conclusions Degradation of sugarcane bagasse requires production of many different enzymes which are regulated by the type and complexity of the available substrate. Our presently reported work opens new possibilities for understanding sugarcane biomass saccharification by A. niger hydrolases and for the construction of more efficient enzymatic cocktails for second-generation bioethanol.

To understand how to improve enzymatic cocktails that can hydrolyze pretreated sugarcane bagasse, we used a genomics approach to investigate which genes and pathways are transcriptionally modulated during growth of A. niger on steam-exploded sugarcane bagasse (SEB. Results Herein we report the main cellulase- and hemicellulase-encoding genes with increased expression during growth on SEB. We also sought to determine whether the mRNA accumulation of several SEB-induced genes encoding putative transporters is induced by xylose and dependent on glucose. We identified 18 (58% of A. niger predicted cellulases and 21 (58% of A. niger predicted hemicellulases cellulase- and hemicellulase-encoding genes, respectively, that were highly expressed during growth on SEB. Conclusions Degradation of sugarcane bagasse requires production of many different enzymes which are regulated by the type and complexity of the available substrate. Our presently reported work opens new possibilities for understanding sugarcane biomass saccharification by A. niger hydrolases and for the construction of more efficient enzymatic cocktails for second-generation bioethanol.

    Full Text Available  Abstract Pen-name (Takhalloss is one of the main features of Persian poetry. It has been a matter of concern among many of Persian language geography poets in the orient at least up to the Mashrouteh era. Pen-name has been promoted among the other Muslim nations throuph Persian poetry. Although it is not as famous in the Arab nations as in the Persian speaking nations, it is known as “Alqab-o-shoara” among the Arab nations and, through this way, it has affected the poetrical wealth of the Arabic poets.   The Present paper, using description-analystic approach, compares the pen-names of Persian and Arabic poets under the title of “pen-names” and investigates their features in both cultures. The main research question is: What are the similarities and differences of poetic-names, in Persian and Arabic poets in terms of the type of name, position and importance? The results showed that Pseudonym by its amazing expansion in Persian poetry has also influenced Arabic poetry. In addition to the factors affecting in the choice of pen-names (like pseudonym, pen-name, nickname..., sometimes such external factors as events, commends, community benefactors and climate, as well as internal factors including the poets’ inner beliefs are associated too. .

  15. Towards Verbalizing SPARQL Queries in Arabic

    Full Text Available With the wide spread of Open Linked Data and Semantic Web technologies, a larger amount of data has been published on the Web in the RDF and OWL formats. This data can be queried using SPARQL, the Semantic Web Query Language. SPARQL cannot be understood by ordinary users and is not directly accessible to humans, and thus they will not be able to check whether the retrieved answers truly correspond to the intended information need. Driven by this challenge, natural language generation from SPARQL data has recently attracted a considerable attention. However, most existing solutions to verbalize SPARQL in natural language focused on English and Latin-based languages. Little effort has been made on the Arabic language which has different characteristics and morphology. This work aims to particularly help Arab users to perceive SPARQL queries on the Semantic Web by translating SPARQL to Arabic. It proposes an approach that gets a SPARQL query as an input and generates a query expressed in Arabic as an output. The translation process combines both morpho-syntactic analysis and language dependencies to generate a legible and understandable Arabic query. The approach was preliminary assessed with a sample query set, and results indicated that 75% of the queries were correctly translated into Arabic.

    Full Text Available Hollywood has a long history of stereotyping the Arab. From The Cafe in Cairo to The Siege, this Arab – invariably male – figures as the religious fundamentalist who sees in terrorism the only way to spread Islam over the entire globe. Having said this, this is not to argue either that Hollywood is ideologically corrupt, or that Arab (Americans are the only ethnic group stereotyped in Hollywood's cultural imagination. Yet while Hollywood’s Orientalism, which is actually based on a fascination with ancient Middle Eastern heritage, reflects a stereotypical depiction of everything Arab, Arab American literature can be seen as the other side of this projection or stereotype. Where Hollywood dramatizes, through the busting of ancient statues for the cause of terrorism, the Arab's disregard for his own culture, novels such as Khaled Hosseini's The Kite Runner and Nada Awar Jarrar's Somewhere, Home set out to preserve precisely a distinct cultural heritage, and go on to celebrate the contemporaneity and complexity of diasporic Afghan and Lebanese experience.

  17. Toward Understanding Arab Women's Cultural Landscapes

    Full Text Available The cultural representation of women in the Arab world is a complex issue due to the sensitivity surrounding their status in the region. We are confronted with many ways in which women are misrepresented and distorted.  There are false claims used by male dominated culture(s in the Arab world about women and their intellectual and physical capabilities. Indeed, Arab women are often prevented from representing themselves.  When they are present, they are conceptualized as serving a decorative purpose. When women are given platforms from which they may speak, they are expected to reiterate male discourses.The paper focuses on the cultural and political marginalization and misrepresentation of Arab women and describes a number of cultural biases against women in Arabic-speaking societies. Based on culturally constructed misconceptions, Arab women are effaced and excluded from decision-making processes both politically, where they are subjugated and denied a social voice in the public sphere in favour of male-dominated discourses, and within the private sphere of the family where they are subordinate to male relatives.

    We used computational and mass spectrometric approaches to characterize the Aspergillus niger secretome. The 11,200 gene models predicted in the genome of A. niger strain ATCC 1015 were the data source for the analysis. Depending on the computational methods used, 691 to 881 proteins were predicted to be secreted proteins. We cultured A. niger in six different media and analyzed the extracellular proteins produced using mass spectrometry. A total of 222 proteins were identified, with 39 proteins expressed under all six conditions and 74 proteins expressed under only one condition. The secreted proteins identified by mass spectrometry were used to guide the correction of about 20 gene models. Additional analysis focused on extracellular enzymes of interest for biomass processing. Of the 63 glycoside hydrolases predicted to be capable of hydrolyzing cellulose, hemicellulose or pectin, 94% of the exo-acting enzymes and only 18% of the endo-acting enzymes were experimentally detected.

    The acuB gene of Aspergillus niger is an ortholog of facB in Aspergillus nidulans. Under carbon-repression conditions, facB is repressed, thereby preventing acetate metabolism when the repressing carbon source is present. Even though facB is reported to be repressed directly by CreA, it is believed...... that a basal level of FacB activity exists under glucose-repressive conditions. In the present study, the effect of deletion of acuB on the physiology of A. niger was assessed. Differences in organic acid and acetate production, enzyme activities and extracellular amino and non-amino organic acid production...... were determined under glucose-repressing and -derepressing conditions. Furthermore, consumption of alternative carbon sources (e.g. xylose, citrate, lactate and succinate) was investigated. It was shown that AcuB has pleiotropic effects on the physiology of A. niger. The results indicate that metabolic...

  10. The "Protests against Charlie Hebdo" in Niger: A Background Analysis

    Directory of Open Access Journals (Sweden)

    Jannik Schritt

    2015-01-01

    Full Text Available In many Muslim countries in West Africa and beyond, “protests against Charlie Hebdo” occurred when citizens went out on the streets following Friday prayers on 16 January 2015. However, only in Niger did these protests turn extremely violent. This report analyses the social, political and religious workings behind the protests in Niger. In doing so, it shows that the so-called “protests against Charlie Hebdo” are only superficially linked to the Muhammad cartoons by the French satirical magazine. Similarly violent protests have occurred in Niger – often in the town of Zinder – for quite different reasons and on different occasions in recent years. The report therefore argues against simplistic notions of religious fundamentalism and shows that the protests can be explained more appropriately in terms of politics and socio-economic exclusion.

    The Tertiary Niger Delta is stratigraphically framed by the Dahomey, Anambra, Abakaliki, Afikpo and Calabar Flank basins. From the apex at Onitsha a fluvial plain splays southwards and translates progressively into a freshwater swamp, succeeded by a mangrove swamp belt. Along the coast is a strip of wave-washed barrier bars indented by large estuaries, fronted by submerged moth bars. Habitation in the delta is on levees, point bars, and barrier bars. These landforms provided the firm salients for buildings the ports that facilitated international trade from the pre-colonial times.There are four lithofacies-clean, pebbly, and muddy sandstones, and mudstones. Their subdivision, based on sedimentary structures, textures and fossil content yields twenty reservoir and seven nonreservoir classes. Their environments of deposition, identified using facies associations, fall into fluvial, wave-and tide-dominated, marginal, and shallow marine, with localised canyons incised into the delta front and filled with deeper marine facies.The reservoirs are composed of 70 90% quartz, 4 15% feldspar, and 3 13% clay matrix, with minor mica, bioclasts, carbonaceous debris, glauconite, and heavy minerals. Grain size varies from very fine to coarse and pebbly, implying the presence of sands of varying textural and compositional maturities. Silica, K-feldspar, and carbonates constitute the cements.Porosity in the reservoirs has remained about the same as at deposition due to low mechanical compaction occasioned by shallow burial. Meteoric water-flushed progradational sequence are characterised by cementation with quartz and kaolinite. In contrast, marine water-flushed transgressive sands show grain coating illite-smectite, chlorite and K-feldspar overgrowths

    Enzymes can be used to catalyze a myriad of chemical reactions and are a cornerstone in the biotechnology industry. Enzymes have a wide range of uses, ranging from medicine with the production of pharmaceuticals to energy were they are applied to biofuel production. However, it is difficult to produce large quantities of enzymes, especially if they are non-native to the production host. Fortunately, filamentous fungi, such as Aspergillus niger, are broadly used in industry and show great potential for use a heterologous enzyme production hosts. Here, we present work outlining an effort to engineer A. niger to produce thermophilic bacterial cellulases relevant to lignocellulosic biofuel production.

    Full Text Available Displacement is one of the characteristics of language and common phenomena in the Arabic language. Not only is this phenomenon limited to Arabic poetry and prose, but it is also broadened, so we can see examples of this in the Qur'an. Because of this phenomenon extensively in Arabic literature and also because of its essence that leads to the transmission of the elements for the first visibility to the other visibility in the sentence and sometimes had to change the grammatical role of the words, its identify helps us in a better understanding of text and the correct translation of it and protects the reader from mistakes. This paper in the descriptive analytical approach tries studying of the phenomenon of the displacement in the Arabic language and bringing its instances in Arabic poetry and prose as well as verses contained in the Holy Quran, to show that through the types and characteristics in the Arabic language and to response to several questions, including: how important is the displacement and what is its types in rhetoric, and the reasons of the displacement, and etc...

    Recently many Arab countries have expressed their interest in adopting nuclear power for electricity generation and seawater desalination in their energy strategies and hence sought assistance from IAEA and Arab Atomic Energy Agency. The Council of the League of Arab States at the summit level encouraged member states to develop peaceful use of atomic energy in different aspects of development, especially in energy generation and to establish a cooperative Arab program in this field. The burden of infrastructure can be reduced significantly if an Arab country forms a sharing partnership with other Arab countries. The sharing can be between two or more Arab states. It can include physical facilities, common programmes and knowledge, which will reflect in economic benefits. The sharing can also contribute in a significant manner to harmonization of codes and standards in general and regulatory framework in particular. This article outlines the major direct benefits of joint nuclear Arab programme to build a Nuclear Power Plants. (author)

  7. Consanguinity and reproductive health among Arabs

    Directory of Open Access Journals (Sweden)

    Al Ali Mahmoud T

    2009-10-01

    Full Text Available Abstract Consanguineous marriages have been practiced since the early existence of modern humans. Until now consanguinity is widely practiced in several global communities with variable rates depending on religion, culture, and geography. Arab populations have a long tradition of consanguinity due to socio-cultural factors. Many Arab countries display some of the highest rates of consanguineous marriages in the world, and specifically first cousin marriages which may reach 25-30% of all marriages. In some countries like Qatar, Yemen, and UAE, consanguinity rates are increasing in the current generation. Research among Arabs and worldwide has indicated that consanguinity could have an effect on some reproductive health parameters such as postnatal mortality and rates of congenital malformations. The association of consanguinity with other reproductive health parameters, such as fertility and fetal wastage, is controversial. The main impact of consanguinity, however, is an increase in the rate of homozygotes for autosomal recessive genetic disorders. Worldwide, known dominant disorders are more numerous than known recessive disorders. However, data on genetic disorders in Arab populations as extracted from the Catalogue of Transmission Genetics in Arabs (CTGA database indicate a relative abundance of recessive disorders in the region that is clearly associated with the practice of consanguinity.

  13. Case Study: Neglected Health Issues in Niger

    Directory of Open Access Journals (Sweden)

    Cameron Neylon

    2017-10-01

    Full Text Available The project “Problemes négligés du système de santé au Niger” focusses on a core set of often-neglected issues that nevertheless have an overall negative impact on health system effectiveness in Niger. For example, poor quality maternal health services result from challenges related to the midwifery profession and from pressures from addressing the effects of illegal termination of pregnancy. Overall health system governance is undermined by weak management of human resources and health information systems as well as problems related to decentralisation of health care provision and dependence on external funding for health projects. LASDEL applies a rapid assessment and qualitative research approach to working with patients and health care professionals to identify the scale and characteristics of these problems. The project goal is to develop an evidence base to support tackling these neglected issues. Développer des recherches sur les « problèmes négligés » dans la gouvernance de la santé, et sur cette base contribuer à des réformes des systèmes de santé permettant une meilleure qualité des soins pour les populations vulnérables. "Develop research on "neglected problems" in the provision of health systems, and through this work, contribute to health system reforms, that provide better quality of care for vulnerable populations." As can be seen above, many of these issues relate to reproductive health and more generally to health issues of disadvantaged groups. Some issues are neglected for political or social reasons meaning that they are not recognised or acknowledged and in some cases are criminalised. Therefore there are profound issues of participant privacy, protection and even safety for this project. Data sharing therefore requires thoughtful anonymisation and selection. The project group is Francophone with limited English language knowledge and the researchers and the context is largely in French. In common with

    2016-12-15

    Phosphate solubilizing fungi have high ability to secrete organic acids. In this study, fungus Aspergillus niger and geological fluorapatite were applied in lead remediation in aqueous solution. Formation and morphology of the lead minerals, e.g., pyromorphite and lead oxalate, were investigated by SEM, XRD, and ATR-IR. The total quantity of organic acids reached the maximum at the sixth day, which improved the concentration of soluble P up to ∼370mg/L from ∼0.4mg/L. The organic acids, especially the oxalic acid, enhance the solubility of fluorapatite significantly. The stable fluoropyromorphite [Pb 5 (PO 4 ) 3 F] is precipitated with the elevated solubility of fluorapatite in the acidic environment. Furthermore, A. niger grows normally with the presence of lead cations. It is shown that >99% lead cations can be removed from the solution. However, immobilization caused by the precipitation of lead oxalate cannot be ignored if the fungus A. niger was cultured in the Pb solution. This study elucidates the mechanisms of lead immobilization by FAp and A. niger, and sheds its perspective in lead remediation, especially for high Pb concentration solution.

The system takes profit of a Multilingual Framework covering four languages (Arabic, English, French, and Spanish, in a way that resources available for each language can be used to improve the results of the others, this is specially important for less resourced languages as Arabic. The approach has been evaluated against Wikipedia pages of the four languages belonging to the medical domain. The core of the system is the definition of a base tagset consisting of the three most represented classes in SNOMED-CT taxonomy and the learning of a binary classifier for each semantic category in the tagset and each language, using a distant learning approach over three widely used knowledge resources, namely Wikipedia, Dbpedia, and SNOMED-CT.

  10. Muslim Feminist Agency and Arab American Literature

    Koegeler-Abdi, Martina

    2017-01-01

    Mohja Kahf’s novel the girl in the tangerine scarf highlights a broad spectrum of Muslim feminist agencies. In this essay I look at how her literary representations negotiate religious and feminist discourses in doing so. I further argue that her focus on empowerment through self......-defined spirituality and religion sets her novel apart within the canon of contemporary Arab American literature, as most other Arab American feminist narratives focus rather on reappropriations of orientalist Scheherazade figures to reclaim the transnational histories of Muslim women’s agency. The genre of the Arab...... to the intersectional specificity encountered by Muslim feminist writers who have to work within both Western Orientalisms and the disapproval of Muslim conservatives who denounce feminism as a Western import and refuse any critique of their own patriarchy. Kahf suggests a constant double critique and careful...

    Full Text Available Language is very important for everyone used to deliver information, ideas, and thought from a person to others. One of the oldest languages in this world is Arabic. It is used in oral and written form and it contributes to the development of Islamic thought tradition in some Islamic texts such as Qur’an, Hadits, Tafsir, Fiqih, Tasawuf, etc. Therefore, it is very important for Moslems to learn Arabic language especially in the realm of Islamic education as to gain deep understanding about the substances or contents (meaning sense of the text. This article discusses about the important roles of Arabic in islamic education to increase the faith quality and good behavior of Moslems.

    The Upper Niger Basin is located in Western Africa, flowing from Guinea Highlands towards the Sahel region. In this area lies the seasonally inundated Niger Inland Delta, which supports important environmental services such as habitats for wildlife, climate and flood regulation, as well as large fishery and agricultural areas. In this study, we present the application of MGB-IPH large scale hydrologic and hydrodynamic model for the Upper Niger Basin, totaling c.a. 650,000 km2 and set up until the city of Niamey in Niger. The model couples hydrological vertical balance and runoff generation with hydrodynamic flood wave propagation, by allowing infiltration from floodplains into soil column as well as representing backwater effects and floodplain storage throughout flat areas such as the Inland Delta. The model is forced with TRMM 3B42 daily precipitation and Climate Research Unit (CRU) climatology for the period 2000-2010, and was calibrated against in-situ discharge gauges and validated with in-situ water level, remotely sensed estimations of flooded areas (classification of MODIS imagery) and satellite altimetry (JASON-2 mission). Model results show good predictions for calibrated daily discharge and validated water level and altimetry at stations both upstream and downstream of the delta (Nash-Sutcliffe Efficiency>0.7 for all stations), as well as for flooded areas within the delta region (ENS=0.5; r2=0.8), allowing a good representation of flooding dynamics basinwide and simulation of flooding behavior of both perennial (e.g., Niger main stem) and ephemeral rivers (e.g., Niger Red Flood tributaries in Sahel). Coupling between hydrology and hydrodynamic processes indicates an important feedback between floodplain and soil water storage that allows high evapotranspiration rates even after the flood passage around the inner delta area. Also, representation of water retention in floodplain channels and distributaries in the inner delta (e.g., Diaka river

    Data about Arab-Americans, a growing ethnic minority, are not routinely collected in vital statistics, registry, or administrative data in the USA. The difficulty in identifying Arab-Americans using publicly available data sources is a barrier to health research about this group. Here, we validate an empirically based probabilistic Arab name algorithm (ANA) for identifying Arab-Americans in health research. We used data from all Michigan birth certificates between 2000 and 2005. Fathers' surnames and mothers' maiden names were coded as Arab or non-Arab according to the ANA. We calculated sensitivity, specificity, and positive (PPV) and negative predictive values (NPV) of Arab ethnicity inferred using the ANA as compared to self-reported Arab ancestry. Statewide, the ANA had a specificity of 98.9%, a sensitivity of 50.3%, a PPV of 57.0%, and an NPV of 98.6%. Both the false-positive and false-negative rates were higher among men than among women. As the concentration of Arab-Americans in a study locality increased, the ANA false-positive rate increased and false-negative rate decreased. The ANA is highly specific but only moderately sensitive as a means of detecting Arab ancestry. Future research should compare health characteristics among Arab-American populations defined by Arab ancestry and those defined by the ANA.

    The Arab countries, 22 in total, are divided into three groups. Group one consists of all countries of the Middle East. The second group is the Arabian Peninsula, and the third group consists of all Arab countries in Africa. The paper outlines the solar density and sunshine hours, as well as wind data in the region and compares them with some industrialized countries. Brief surveys of various solar energy projects are tabulated: that is solar, wind and biomass. Several specific major projects in various parts of the Arab World will be discussed. More specifically, the cooling of the solar energy research building in Baghdad (120 tons of solar absorption chillers, 80 tons of heat pumps), the heating of King Abdu-Asis Airborne and Physical Training School near Tabuk, Saudi Arabia, the 350 kW PV. field of the solar energy village near Riyadh and the 100 kW solar thermal plant in Kuwait are discussed. It is worth noting that the present photovoltaic capacity in the Arab world is more than 3.0 MW and the yearly installation potential per year is 2.0 MW. There are at least five photovoltaic production facilities in the Arab countries. Two of them in Saudi Arabia with capacity of 400 kW, one in Iraq with a capacity of 200 kW, one in Tunisia with a capacity of 100 kW and on in Algeria with capacity of 100 kW. The Arab countries can absorb 5MW per year and more countries like Egypt, Sudan, Morocco, Jordan and Libya are thinking of having their own production capabilities. Five desalination plants are also mentioned, plus the Yanbu plant of 240m/day, which is one of the largest in the world. The potential of wind energy utilisation is considered. Obstacles hindering the process of solar energy in the region are also outlined. (author). 11 refs, 1 fig., 4 tabs

  16. Fumonisin and Ochratoxin Production in Industrial Aspergillus niger Strains

    2011-01-01

    Aspergillus niger is perhaps the most important fungus used in biotechnology, and is also one of the most commonly encountered fungi contaminating foods and feedstuffs, and occurring in soil and indoor environments. Many of its industrial applications have been given GRAS status (generally regarded as safe). However, A. niger has the potential to produce two groups of potentially carcinogenic mycotoxins: fumonisins and ochratoxins. In this study all available industrial and many non-industrial strains of A. niger (180 strains) as well as 228 strains from 17 related black Aspergillus species were examined for mycotoxin production. None of the related 17 species of black Aspergilli produced fumonisins. Fumonisins (B2, B4, and B6) were detected in 81% of A. niger, and ochratoxin A in 17%, while 10% of the strains produced both mycotoxins. Among the industrial strains the same ratios were 83%, 33% and 26% respectively. Some of the most frequently used strains in industry NRRL 337, 3112 and 3122 produced both toxins and several strains used for citric acid production were among the best producers of fumonisins in pure agar culture. Most strains used for other biotechnological processes also produced fumonisins. Strains optimized through random mutagenesis usually maintained their mycotoxin production capability. Toxigenic strains were also able to produce the toxins on media suggested for citric acid production with most of the toxins found in the biomass, thereby questioning the use of the remaining biomass as animal feed. In conclusion it is recommended to use strains of A. niger with inactive or inactivated gene clusters for fumonisins and ochratoxins, or to choose isolates for biotechnological uses in related non-toxigenic species such as A. tubingensis, A. brasiliensis, A vadensis or A. acidus, which neither produce fumonisins nor ochratoxins.

  17. Nigeria. Petroleum, pollution and poverty in the Niger Delta

    International Nuclear Information System (INIS)

    2009-06-01

    The oil industry has operated in the Niger Delta in Nigeria for more than half a century - bringing almost no benefit to the people living there. Instead, widespread and unchecked human rights violations have pushed many people deeper into poverty and deprivation, fuelled conflict and led to a pervasive sense of powerlessness and frustration. This multidimensional crisis is driven by many factors - abuses committed by the security forces and militant groups, extensive pollution of land and water, corruption, serious corporate bad practice and government neglect. Nigeria: Petroleum, pollution and poverty in the Niger Delta focuses on one dimension of the crisis: the impact of pollution and environmental damage caused by the oil industry on the human rights of those living in the Niger Delta. Many people in the oil-producing areas of the delta rely on fisheries, subsistence agriculture and associated processing industries for their livelihood. Decades of pollution and environmental damage have resulted in violations of the right to an adequate standard of living - including food and water - violations of the right to gain a living through work, and violations of the right to health. The report examines who is responsible for this situation in a context where multinational oil companies have been operating for decades. It highlights how companies take advantage of the weak regulatory systems that characterize many poor countries, and how the poorest people are often the most vulnerable to exploitation. The people of the Niger Delta have seen their human rights undermined by oil companies that their government can not - or will not - hold to account. They have been systematically denied access to information about how oil exploration and production will affect them, and are repeatedly denied access to justice. The Niger Delta provides a stark case study of the lack of accountability of a government to the people, and of multinational companies' almost total lack of

    The state of oil and gas production in each of twelve Arab states in 1996 is reviewed. A table of proved oil reserves and production in these countries as at the end of 1995 is provided. For Arab oil producers, 1996 was a good year in price terms. Crude oil was selling at an average of $3 a barrel more than in 1995. Factors contributing to prices rises were the increase in demand accompanying global economic growth, especially in the developing economies of Asia, which was not matched by supply growth, and the news that Iraq is unlikely to return to international markets in the near future.

    Full Text Available The paper is analysing the geopolitical structure and dynamics of Arab space. Based on structural analysis of social, political, cultural and spatial changes the key-problems and geopolitical features are recognized. Arab space is – more or less – the largest ‘shatter belt’ known by contemporary crises and similar processes in the near past. These are caused by inner and, even more, by outer geopolitical factors in the large regional surrounding. The western economic and military forces are perhaps loosing the role of key-factor in the area. In the near future, Asiatic powers might play a dominant role.

  5. self-criticism to Arab and Muslim intellectuals

    Directory of Open Access Journals (Sweden)

    Fachrizal Halim

    2007-06-01

    Full Text Available Contemporary Arab Thought: Studies in Post-1967 Arab Intellectual Historyis written as a self-criticism addressed to Arab and Muslim intellectuals, especially those who reside in the West. The Arab intellectuals or Muslims alike, who have received Western education and have decided to live in Western countries in the first half of twentieth century, have actually benefited from their modern secular education. The liberalization of U.S. immigration laws in 1965 for non-European immigrants has even enlarged the number of Arabs and Muslims who have trained in the best institutions in the U.S. By the dawn of the twentieth century, the number of Arab intellectuals who reside in the West is estimated to double, as the result of the emergence of a second generation. However, the large number of educated Arab people does not always fulfill the promise of transformation of the social conditions of the Arab World. Far from being ‘organic intellectuals’, to use Gramsci’s favorite term, who would transform Arab societies from imperialism and Western hegemony, and the impact of dependency on the so called ‘globalization,’ most Arab thinkers in the West as well as the elite in the Arab world have been party to Western capitalist interests which aim to control the Arab World. By no means denigrating the works of Isma‘il Raji al-Faruqi, Edward Said, Ghada Hashem Talhami, Halim Barakat, or the feminist Leila Ahmad, to mention some brilliant Arab intellectuals, most Arab thinkers in the West seem to have forgotten the social conditions of the Arab world that have been in acute crisis since the mid nineteenth century or from the time colonialism stepped into the Arab world. Pseudo modernization—to say that there has never been any modernization as it emerged from the middle class as in Europe, but was initiated mainly by the elites—has kept Arab intellectuals in the West completely in the dark and unable to offer radical solution to the crises of

    The difficult and tense political climate Arab populations are currently facing may be exacerbating mental health issues, reducing forms of social support in friend circles, and decreasing the desire to seek health care. There is room to better understand the mental health needs of Arab women residing in the United States and to develop policies and interventions that keep these women safe and in care. This column reviews two recent studies; the first examines barriers to reporting intimate partner violence and depression among Arab American women and the second highlights stressors and social support for Arab women immigrants throughout their immigration experience. © 2017 AWHONN, the Association of Women’s Health, Obstetric and Neonatal Nurses.

    The 22 Arab nations have a unique genetic structure, which reflects both conserved and diverse gene pools due to the prevalent endogamous and consanguineous marriage culture and the long history of admixture among different ethnic subcultures descended from the Asian, European, and African continents. Human genome sequencing has enabled large-scale genomic studies of different populations and has become a powerful tool for studying disease predictions and diagnosis. Despite the importance of the Arab genome for better understanding the dynamics of the human genome, discovering rare genetic variations, and studying early human migration out of Africa, it is poorly represented in human genome databases, such as HapMap and the 1000 Genomes Project. In this review, I demonstrate the significance of sequencing the Arab genome and setting an Arab genome reference(s) for better understanding the molecular pathogenesis of genetic diseases, discovering novel/rare variants, and identifying a meaningful genotype-phenotype correlation for complex diseases.

    Full Text Available In this article we discuss three interrelated topics, framed within discourses of individual and collective human rights, right of self-determination, democratic processes, people`s uprisings, and geopolitical (imbalances. First, we are interested in the situation of Western Sahara and the 37 years of ongoing Moroccan occupation; we refer to this country as Africa’s last colony. Discussion leads us to reflection of the political strategies of Sahrawis to achieve their national liberation, one of them being Gdeim Izik camp, understood by some relevant authors as the beginning of the »Arab spring«. The »Arab spring« is the second focus of our discussion. We offer a timetable and stress the context of events from the Western Sahara attempt in Gdeim Izik, popular uprisings in Tunisia, Egypt and Yemen that ended in the resignations of their leaders and governments, civil wars in Syria and Libya, to bigger and smaller protests and their consequences in Oman, Kuwait, Bahrain, Jordan, Morocco, Mauretania, Algeria, Sudan, Saudi Arabia, Iraq, Lebanon and Djibouti. We try to offer a deconstruction and reconstruction of the »Arab spring«. In the third part, we discuss the Israeli/Palestinian conflict and the perspectives for solution. The conclusion reflects on the strategic, social and political implications of the »Arab spring«, the role and response of the international community, and the new global wave of resistance against political and financial elites.

    Full Text Available   This research aimed at knowing the ability of applying Synectics strategy in teaching rhetoric in Arabic language at secondary schools and universities   Synectics is identifying as a process of joining elements that has no obvious relationship using the rhetoric arts, especially “metaphor” in addition to logical arts especially “analogy,” within a methodology aims to reach creative solutions to problems. This definition is completely similar to Arabic rhetoric such as analogy and metaphor.   When metaphor in language contains aesthetic and rhetorical values in expression, it carries explanatory connotations in philosophy and science which is the using of a specific experience to shed the light on another one. It also helps us to comprehend, insight and clarifying and explaining the concepts. And what we mean with analogy in Arabic language is nearer to simile which is one of the rhetoric arts.   This research will review the Synectics strategy, how the western scientists applied it to develop creativity, and to what extent it is suitable to teach Arabic rhetoric subject in the university and secondary stage. In addition, It will provide application forms about applying Synectics strategy which will at the same time increase creativity of the students in all fields.

    Biosorption is a property of certain types of inactive, dead, microbial biomass to bind and concentrate heavy metals from even very dilute aqueous solutions. Biomass exhibits this property, acting just as a chemical substance, as an ion exchanger of biological origin. It is particularly the cell wall structure of certain algae, fungi and bacteria which was found responsible for this phenomenon. Some of the biomass types come as a waste by-product of large-scale industrial fermentations (the mold Rhizopus or the bacterium Bacillus subtilis). Other metal-binding biomass types, certain abundant seaweeds (particularly brown algae e.g. Sargassum, Ecklonia), can be readily collected from the oceans. These biomass types, serving as a basis for metal biosorption processes, can accumulate in excess of 25% of their dry weight in deposited heavy metals: Pb, Cd, U, Cu, Zn, even Cr and others. Sorption experiments using the Aspergillus niger fungus for cadmium removal were carried out to study the factors influencing and optimizing the biosorption of this metal. The effects of pH, time, biomass concentration, and initial concentration of the heavy metal on the rate of metallic biosorption were examined. (author)

Transition to motherhood is a universal phenomenon in which every culture has its own expectations and varying supports for women moving through this transition. International studies have provided models or categories of maternal responses related to cultural aspects of transition to motherhood. However, no known research has focused on transition to motherhood among Gulf Arab women. In the initial cohort seventeen first time Gulf Arab mothers in the United Arab Emirates were interviewed during the following three times: before childbirth, two-four weeks after childbirth, and forty-days after childbirth. A second cohort of seventeen first time new mothers was interviewed after childbirth in Sultanate of Oman. Four patterns were identified as indicators of change as women transitioned into motherhood: 1) Women's personal transition: women changed from feeling of freedom to feeling of dependency to self-confidence. 2) Mother/baby relationships: women changed from fear, anxiety, and uncertainty to feelings of care and confidence. 3) Family influences: women experienced family support to being integrated and feeling respected by family. 4) Cultural/religious beliefs and practices: women felt they were initially observers of culture, to experiencing cultural/religious beliefs and practices. This was followed by accomplishment in childbearing and childrearing practices. As Gulf Arab new mothers made the transition to motherhood, four implications for international nursing practice emerged: 1) patient teaching to help relieve anxiety, fears, and uncertainty, 2) facilitation of mother/baby relationships, 3) family-centered care, and 4) the importance of cultural/religious beliefs and practices to new mothers.

    Arab Atomic Energy Agency (AAEA) is one of the organizations of the League of Arab States (LAS). AAEA is working within the framework of the LAS to coordinate the scientific efforts of the Arab Countries in the field of peaceful uses of atomic energy. So, AAEA works hard to enhance the socio-economical development in Arab countries by promoting the peaceful applications of atomic energy in many aspects of life. The Arab Authority contributes for the implementation of training programs for Arab staff in the field of parameters mentioned above through the implementation of training courses, workshops and expert meetings in addition to scientific visits exchanged between the researchers and Arabs scientists and translation of books from the International Atomic Energy Agency (IAEA) to the Arabic language and circulated to the Arab countries. At Arab Summits (Riyadh - 2007 - Damascus and Doha 2008 - 2009), AAEA elaborates 12 projects on the Arab strategy for the peaceful uses of atomic energy until 2020 and planed all applications of atomic energy. Integration of radioisotopes production in the Arab countries is among these projects. This project aims to unify efforts and coordinate cooperation between the Arab countries together to develop the human potential and benefit from the expertise available in some Arab countries in the production of radioisotopes to insure the integration between Arab countries. Nuclear and radioactive facilities in Arab countries are:- Research reactors (RRs) that can produce isotopes (Egypt -2, -2 Algeria, Libya -1) and (-1 Morocco, Syria -1).- Ions accelerators (cyclotron) for isotope production (Morocco, Algeria, Syria, Saudi Arabia, Egypt).- Ions accelerators (VDG) for research and analysis (Egypt, Syria, Lebanon, Algeria and Jordan).- Electron accelerator (LINAC) for research and industry applications (Tunisia, Egypt, Syria, Morocco, Saudi Arabia, Algeria, UAE and Kuwait).- Electron accelerators (LINAC) for nuclear medicine therapy

    The ability of the ascomycete Aspergillus niger N402 to transform exogenous progesterone was investigated. We found that this strain has steroid-hydroxylating activity and can introduce a hydroxyl group into the progesterone molecule mainly at positions C11(α) and C21 with predominant formation of 21-hydroxyprogesterone (deoxycortone). In addition, formation of 6β,11α-dihydroxyprogesterone was also observed. Studying the effects of the growth medium composition and temperature on progesterone conversion by A. niger N402 showed that the most intense accumulation of 21-hydroxyprogesterone occurred in minimal synthetic medium at 28°C. Increasing the cultivation temperature to 37°C resulted in almost complete inhibition of the hydroxylase activity in the minimal medium. In the complete medium, a similar increase in temperature inhibited 11α-hydroxylase activity and completely suppressed 6β-hydroxylase activity, but it produced no effect on 21-hydroxylating activity.

    The production of transglucosidase by Aspergillus niger was examined in batch culture with thin-layer chromatography (t.l.c.). Corn steep liquor was used as the nitrogen source and the activities obtained with four different carbon sources were examiend both qualitatively and quantitatively. Prompted by the non-quantitative nature of the t.l.c. assay technique, a quantiative transglucosidase assay procedure was developed subsequently. This was based on the hydrolysis of alpha-methyl-D-glucoside which was shown to be unaffected not only by amyloglucosidase of A. niger but also by that from a number of other organisms. The glucose released was measured by the glucose oxidase-peroxidase reagent, thus providing a rapid and reliable quantitative assay procedure for determining transglucosidase in the presence of amyloglucosidase.

    Full Text Available Good indoor environmental quality is desired for a healthy indoor environment. The microbial growth under indoor environments contribute to the poor indoor environmental quality that can cause various of health problems. In this study, the applications of three types of antifungals to prevent microbial migration, subsequent growth and bio-deterioration of the substrates. The aim of this research was to evaluate the coating-bio resistance in remediation of indoor fungal using three types of antifungals with different types of wall finishing materials. The treatment was exposed to optimum temperature and relative humidity at 30°C and 90% respectively. The potassium sorbate, zinc salicylate and calcium benzoate are tested against Aspergillus niger which is collected from indoor rooms. This study has revealed the growth of A. niger are more affected by the potassium sorbate on thick wallpaper, which is the percentage growth are 47%.

    Three classes of coloured mutations, viz., fawn, yellow and green, occurred recurrently among the population following UV- and γ-radiation from Co 60 of a wild Aspergillus niger strain 350. Ten mutants were picked up and complementation tests were performed by growing them in pairwise combinations. In two cases, allelic mutants of the same colour were observed. All these mutants were again grown in pairwise crosses with a brown A. niger mutant of different lineage. A poor heterokaryotic growth was, however, observed in one combination which later produced a diploid heterozygous nucleus. It segregated spontaneously to develop a large variety of colonies ranging from haploidy to diploidy including aneuploids. These have been analysed genetically and the possible explanations have been given. (auth.)

    New steps of NAD metabolism were shown in Aspergillus niger. Radioactive nicotinic acid and nicotinamide were incorporated into nicotinamide ribose diphosphate ribose (NAmRDPR), which had been isolated from the culture filtrate. The enzyme preparation of the mold degraded NAmRDPR to form nicotinamide mononucleotide and nicotinic acid under the neutral and alkaline conditions. In the acid extracts of the mycelia grown on the radioactive precursors, high level of radioactivity was detected on NAD. The experimental results showed that the Preiss-Handler pathway and the NAD cycling system function in the NAD biosynthesis in A. niger. A part of the radioactive precursors was also incorporated into nicotinic acid ribonucleoside, which was thought to be formed from nicotinic acid mononucleotide. (auth.)

    Both of culture temperature and pH value had impacts on the degree of uranium extraction through changing types and concentrations of mixed organic acids produced by Aspergillus niger, and significant interactions existed between them though pH value played a leading role. And with the change of pH value of mixed organic acids, the types and contents of mixed organic acids changed and impacted on the degree of uranium extraction, especially oxalic acid, citric acid and malic acid. The mean degree of uranium extraction rose to peak when the culture temperature was 25 deg C (76.14 %) and pH value of mixed organic acids was 2.3 (82.40 %) respectively. And the highest one was 83.09 %. The optimal culture temperature (25 deg C) of A. niger for uranium leaching was different from the most appropriate growing temperature (37 deg C). (author)

    Aspergillus niger A-5 produced beta-glucosidase, exocellobihydrolase (C1 enzyme) and endo-1, 4-beta-glucanase (Cx enzyme) in a culture medium containing farm residues of plant origin: wheat straw, ground maize stalks, wheat bran, and micricell as substrates. Maize stalk and wheat bran were the best inducers of the cellulase complex. Intensive aeration stimulated growth and enzyme synthesis. The highest beta-glucosidase activity (54 units/mL) was observed after 96 h of cultivation.

    1973-01-01

    A new nonphosphorylative pathway for gluconate degradation was found in extracts of a strain of Aspergillus niger. The findings indicate that gluconate is dehydrated into 2-keto-3-deoxy-gluconate (KDG), which then is cleaved into glyceraldehyde and pyruvate. 6-Phosphogluconate was not degraded under the same conditions. In addition, KDG was formed from glyceraldehyde and pyruvate. Very weak activity was obtained when glyceraldehyde 3-phosphate replaced glyceraldehyde in this reaction. PMID:4698214

    1981-11-01

    A mathematical model for the study of gluconic acid fermentation by Aspergillus niger has been developed. The model has been deduced from the basic biological concept of multicellular filamentous microorganisms, i.e. cell population balance. It can be used to explain the behaviour of both batch and continuous cultures, even when in a lag phase. A new characteristic, involving the existence of dual equilibrium stages during fermentation, has been predicted using this mathematical model. (Refs. 6).

    Full Text Available The industrial A. niger strain producing citric acid was mutagenized with the use of new chemical mutagens: free nitroxyl radicals. Strains of higher citric acid production yield were obtained. Citric acid was produced in a shorter time compared to the initial strain. During 6-12 months of storage most of the strains preserved their positive features which proves that mutants with profitable biotechnological properties were obtained. These mutants are used in industrial process.

    Colonies of Aspergillus niger are characterized by zonal heterogeneity in growth, sporulation, gene expression and secretion. For instance, the glucoamylase gene glaA is more highly expressed at the periphery of colonies when compared to the center. As a consequence, its encoded protein GlaA is mainly secreted at the outer part of the colony. Here, multiple copies of amyR were introduced in A. niger. Most transformants over-expressing this regulatory gene of amylolytic genes still displayed heterogeneous glaA expression and GlaA secretion. However, heterogeneity was abolished in transformant UU-A001.13 by expressing glaA and secreting GlaA throughout the mycelium. Sequencing the genome of UU-A001.13 revealed that transformation had been accompanied by deletion of part of the fluG gene and disrupting its 3' end by integration of a transformation vector. Inactivation of fluG in the wild-type background of A. niger also resulted in breakdown of starch under the whole colony. Asexual development of the ∆fluG strain was not affected, unlike what was previously shown in Aspergillus nidulans. Genes encoding proteins with a signal sequence for secretion, including part of the amylolytic genes, were more often downregulated in the central zone of maltose-grown ∆fluG colonies and upregulated in the intermediate part and periphery when compared to the wild-type. Together, these data indicate that FluG of A. niger is a repressor of secretion.

    The aim of the current study was to address a gap in the literature by determining prevalence, specific types of violence, and risk factors of intimate partner violence (IPV) among Israeli born Arab women compared with Israeli born Jewish women. The following measures were compared: demographic and socioeconomic measures; measures relating to the characteristics of the violence, that is, the three types of violence (physical, emotional, and verbally threatening), sense of danger, and history of violence in childhood; family support levels; and perpetrator characteristics. The sample consisted of 154 Israeli born Arab women and 149 Israeli born Jewish women who were staying in shelters for victims of domestic violence in Israel. A comparison of the two groups revealed that the Arab women were exposed to more physical violence and received less family support than did their Jewish counterparts. The proportion of Arab perpetrators with access to weapons was higher than that of Jewish perpetrators, whereas the proportion of police complaints against Jewish perpetrators was higher than that against Arab perpetrators. Arab women were also younger, less educated, and less a part of the workforce than Jewish women. The contribution of the woman's age to the variance in levels of physical violence was negative and significant. In contrast, the contribution of her sense of danger, and various perpetrator characteristics, was positive. Moreover, the interaction between sense of danger × ethnicity contributed significantly to levels of violence. This study extends the existing knowledge about the contribution of ethnicity as one of many variables that play a role in the lives of women who are victims of domestic violence and highlights the need to develop, in particular, unique individual, community, and social interventions for Arab women in Israeli society.

    Biosorption of 241 Am by a fungus A. niger, including the spore and hyphae, was investigated. The preliminary results showed that the adsorption of 241 Am by the microorganism was efficient. More than 96% of the total 241 Am could be removed from 241 Am solutions of 5.6-111 MBq/l (C 0 ) by spore and hyphae of A. niger, with adsorbed 241 Am metal (Q) of 7.2-142.4 MBq/g biomass, and 5.2-106.5 MBq/g, respectively. The biosorption equilibrium was achieved within 1 hour and the optimum pH range was pH 1-3. No obvious effects on 241 Am adsorption by the fungus were observed at 10-45 deg C, or in solutions containing Au 3+ or Ag + , even 2000 times above the 241 Am concentration. The 241 Am biosorption by the fungus obeys the Freundlich adsorption equation. There was no significant difference between the adsorption behavior of A. niger spore and hyphae. (author)

    Objective The purpose of this study was to examine the nutritional adequacy and dietary composition among women residing in Zinder and Maradi of Niger, and the factors that affect the variety of their dietary intake. Methods Data from 3360 women of ages 15-49 were used in the analysis. The variable of interest was the Women Dietary Diversity Score (WDDS), which is the simple sum of scores of the 9 categorized food groups, ranging from 0 to 9. Lower values for WDDS indicate nutritionally inadequate dietary diversity. Analysis included descriptive, Mann-Whitney U test and linear regression. Results The majority of the participants were residing in the Maradi Region (56.7%) and were living in households with both male and female adults (94.9%). The mean WDDS was 3.5 in Zinder compared to 2.5 in Maradi (p Hunger Scale (HHS) had a negative and significant effect on WDDS. Conclusion Niger has one of the highest concentrations of malnutrition in the world. In 2012, approximately 2.5 million Nigeriens were affected by malnutrition. Our study results reinforce the importance to conduct more studies that examine the nutritional intake of women in Niger.

    Full Text Available Niger is an oleaginous species whose cultivation has been spreading, but there is not much information on the adverse conditions during its seedling establishment. This study aimed at evaluating the effects of substrate water availability and seed water content on niger germination. Seeds were moistened using the humid atmosphere method for 0; 24; 48; and 72 hours, obtaining the water contents of 7.0 %, 12.8 %, 16.8 % and 32.2 %. Then, they were sown in substrate moistened with PEG 6000 solutions with different osmotic potentials: 0.0 MPa (control, -0.1 MPa, -0.2 MPa, -0.3 MPa and -0.4 MPa. A completely randomized design, in a 4 x 5 factorial scheme (water content x osmotic potential, with four replications of 50 seeds, was used. First count and germination percentage, germination speed index and mean time, shoot and root length and seedlings dry weight were evaluated. The reduction in the substrate osmotic potential decreases the niger seed germination and seedling growth, regardless of water content, but with a higher evidence in seed water contents below 32.2 % and 12.8 %, respectively.

    1999-12-01

    In the Maradi district of southwestern Niger, the country¿s commercial hub, children are born with business sense. Parents in the district expect their young daughters to take part in the region¿s business activities by selling products at village markets. Therefore, only 13% of girls in the district attend school and during market days, classrooms are almost empty, but particularly devoid of female students. Students in Sabon Machi village have school vacation every Tuesday in order to attend the weekly market, then catch up on coursework on Wednesdays. Parents approve of such district norms because they prefer to keep their girls at home to help with household chores. Otherwise, they enroll their daughters in a Koranic school, where they can learn the basics of becoming a wife. Girls in this part of Niger are either promised to someone else in the future or they are under the control of their mothers, who are charged with teaching daughters what they need to know to be proper wives. Girls sell market products to slowly accumulate funds for their dowries. Also with regard to daughters, many parents believe that school attendance is synonymous with unwanted pregnancies, abortions, and other sorts of aberrations. Niger¿s government and nongovernmental organizations (NGOs) are wondering how to convince parents in this region to send their daughters to school. Some approaches employed to reassure and convince parents to that end are described.

  14. Floods in the Niger basin - analysis and attribution

    This study addresses the increasing flood risk in the Niger basin and assesses the damages that arise from flooding. Statistics from three different sources (EM-DAT, Darthmouth Flood Observatory, NatCat Munich RE) on people affected by floods show positive trends for the entire basin beginning in the 1980s. An assessment of four subregions across the Niger basin indicates even exponential trends for the Sahelian and Sudanian regions. These positive trends for flooding damage match up to a time series of annual maximum discharge (AMAX): the strongest trends in AMAX are detected in the Sahelian and Sudanian regions, where the population is also increasing the fastest and vulnerability generally appears to be very high. The joint effect of these three factors can possibly explain the exponential increase in people affected by floods in these subregions. In a second step, the changes in AMAX are attributed to changes in precipitation and land use via a data-based approach within a hypothesis-testing framework. Analysis of rainfall, heavy precipitation and the runoff coefficient shows a coherent picture of a return to wet conditions in the basin, which we identify as the main driver of the increase in AMAX in the Niger basin. The analysis of flashiness (using the Richards-Baker Index) and the focus on the "Sahel Paradox" of the Sahelian region reveal an additional influence of land-use change, but it seems minor compared to the increase in precipitation.

    The objective was to determine the contribution of female genital cutting to genital fistula formation in Niger from the case records of a specialist fistula hospital. A retrospective review was undertaken of the records of 360 patients seen at the Danja Fistula Center, Danja, Niger, between March 2014 and September 2016. Pertinent clinical and socio-demographic data were abstracted from the cases identified. A total of 10 fistulas resulting from gurya cutting was obtained: 9 cases of urethral loss and 1 rectovaginal fistula. In none of the cases was genital cutting performed for obstructed labor or as part of ritual coming-of-age ceremonies, but all cutting procedures were considered "therapeutic" within the local cultural context as treatment for dyspareunia, lack of interest in or unwillingness to engage in sexual intercourse, or female behavior that was deemed to be culturally inappropriate by the male spouse, parents, or in-laws. Clinical cure (fistula closed and the patient continent) was obtained in all 10 cases, although 3 women required more than one operation. Gurya cutting is an uncommon, but preventable, cause of genital fistulas in Niger. The socio-cultural context which gives rise to gurya cutting is explored in some detail.

    Technological and cultural innovations as well as climate changes are thought to have influenced the diffusion of major language phyla in sub-Saharan Africa. The most widespread and the richest in diversity is the Niger-Congo phylum, thought to have originated in West Africa ∼ 10,000 years ago (ya). The expansion of Bantu languages (a family within the Niger-Congo phylum) ∼ 5,000 ya represents a major event in the past demography of the continent. Many previous studies on Y chromosomal variation in Africa associated the Bantu expansion with haplogroup E1b1a (and sometimes its sublineage E1b1a7). However, the distribution of these two lineages extends far beyond the area occupied nowadays by Bantu-speaking people, raising questions on the actual genetic structure behind this expansion. To address these issues, we directly genotyped 31 biallelic markers and 12 microsatellites on the Y chromosome in 1,195 individuals of African ancestry focusing on areas that were previously poorly characterized (Botswana, Burkina Faso, Democratic Republic of Congo, and Zambia). With the inclusion of published data, we analyzed 2,736 individuals from 26 groups representing all linguistic phyla and covering a large portion of sub-Saharan Africa. Within the Niger-Congo phylum, we ascertain for the first time differences in haplogroup composition between Bantu and non-Bantu groups via two markers (U174 and U175) on the background of haplogroup E1b1a (and E1b1a7), which were directly genotyped in our samples and for which genotypes were inferred from published data using linear discriminant analysis on short tandem repeat (STR) haplotypes. No reduction in STR diversity levels was found across the Bantu groups, suggesting the absence of serial founder effects. In addition, the homogeneity of haplogroup composition and pattern of haplotype sharing between Western and Eastern Bantu groups suggests that their expansion throughout sub-Saharan Africa reflects a rapid spread followed by

    Discoveries from the human genome, HapMap, and 1000 genome projects have collectively contributed toward the creation of a catalog of human genetic variations that has improved our understanding of human diversity. Despite the collegial nature of many of these genome study consortiums, which has led to the cataloging of genetic variations of different ethnic groups from around the world, genome data on the Arab population remains overwhelmingly underrepresented. The National Arab Genome project in the United Arab Emirates (UAE) aims to address this deficiency by using Next Generation Sequencing (NGS) technology to provide data to improve our understanding of the Arab genome and catalog variants that are unique to the Arab population of the UAE. The project was conceived to shed light on the similarities and differences between the Arab genome and those of the other ethnic groups.

    Full Text Available The scientific contribution in deciphering drama series falls under the discipline of understanding the narratology of distinctive cultures and traditions within specific contexts of certain societies. This article spells out the interferences deployed by the provocations that are induced through the functions of values in modeling societies which are projected through the transmission of media. The proposed operational model consists of providing an à priori design of common Arab values assimilated into an innovative grid analysis code book that has enabled the execution of a systematic and reliable approach to the quantitative content analysis performance. Additionally, a more thorough qualitative content analysis has been implemented in terms of narratolgy where actions have been evaluated based on the grid analysis code book for a clearer perception of Arab values depicted in terms of their context within the Arab drama milieu. This approach has been deployed on four Arab drama series covering the transnational/national and non-divisive/divisive media aspects in the intention of extracting the transmitted values from a common identity perspective for cause of divulging Arab people’s expectancies.

    2006-01-01

    Full Text Available Herbal remedies are widely used for the treatment and prevention of various diseases and often contain highly active pharmacological compounds. Many medicinal herbs and pharmaceutical drugs are therapeutic at one dose and toxic at another. Toxicity related to traditional medicines is becoming more widely recognized as these remedies become popular in the Mediterranean region as well as worldwide. Most reports concerning the toxic effects of herbal medicines are associated with hepatotoxicity although reports of other toxic effects including kidney, nervous system, blood, cardiovascular and dermatologic effects, mutagenicity and carcinogenicity have also been published in the medical literature. This article presents a systematic review on safety of traditional Arab medicine and the contribution of Arab scholars to toxicology. Use of modern cell biological, biochemical, in vitro and in vivo techniques for the evaluation of medicinal plants safety is also discussed.

    Full Text Available Text normalization is an important technique in document image analysis and recognition. It consists of many preprocessing stages, which include slope correction, text padding, skew correction, and straight the writing line. In this side, text normalization has an important role in many procedures such as text segmentation, feature extraction and characters recognition. In the present article, a new method for text baseline detection, straightening, and slant correction for Arabic handwritten texts is proposed. The method comprises a set of sequential steps: first components segmentation is done followed by components text thinning; then, the direction features of the skeletons are extracted, and the candidate baseline regions are determined. After that, selection of the correct baseline region is done, and finally, the baselines of all components are aligned with the writing line.  The experiments are conducted on IFN/ENIT benchmark Arabic dataset. The results show that the proposed method has a promising and encouraging performance.

Domestication designates the type of translation in which a transparent and fluent style is adopted to minimize the strangeness of the foreign text for the target language readers; while foreignization means a target text is deliberately produced to break target conventions by retaining something of the foreignness of the original.Most of Said's work have been translated into Arabic; some have been translated twice, and some three times.  One of these translations forms the core of this paper, which attempts to discuss foreignization strategy. To accomplish this task, Edward Said's Orientalism (1978/2003 is chosen as the source text (ST, and the Arabic translation undertaken by Kamal Abu Deeb (1981/1995 is chosen as the target text (TT.

ADP’s final goal is to provide a number of tools that can enable scholars to effectively query, compare and investigate all known variants of the text that will be encoded as far as possible in compliance with the Text Encoding Initiative (TEI guidelines. The paper addresses a number of issues involved in the process of digitalising manuscripts included in the two existing editions (Ciasca 1888 and Marmardji 1935, adding variants in unedited manuscripts, encoding and lemmatising the text. Issues involved in the design of the ADP include presentation of variants, choice of the standard text, applicability of TEI guidelines, automatic translation between different encodings, cross-edition concordances and principles of lemmatisation.

    Al-Hadhrami, Ahmed A N; Allen, Mike; Moffatt, Colin; Jones, Allison E

    2015-02-01

    From each of four Arabic countries; Morocco, Tunisia, Jordan and Oman, 150 participants produced handwriting samples which were examined to assess whether national characteristics were discernible. Ten characters, which have different configurations depending upon their position in the word, along with one short word, were classified into distinguishable forms, and these forms recorded for each handwriting sample. Tests of independence showed that character forms used were not independent of country (phandwriting samples that underwent 'blind' classification. When the countries were combined into two regions, North Africa and Middle East, the grouping was more marked. Thus, there appears to be some scope for narrowing down the nationality, and particularly the wider geographical region of an author based upon the character forms they use in Arabic handwriting.

    Full Text Available Social media is a huge source of information. And is increasingly being used by governments, companies, and marketers to understand how the crowd thinks. Sentiment analysis aims to determine the attitudes of a group of people that are using one or more social media platforms with respect to a certain topic. In this paper, we propose a semantic approach to discover user attitudes and business insights from social media in Arabic, both standard and dialects. We also introduce the first version of our Arabic Sentiment Ontology (ASO that contains different words that express feelings and how strongly these words express these feelings. We then show the usability of our approach in classifying different Twitter feeds on different topics.

    Rashed, Abdullah; Santos, Henrique

    Basically, neglecting the human factor is one of the main reasons for system failures or for technology rejection, even when important technologies are considered. Biometrics mostly have the characteristics needed for effortless acceptance, such as easiness and usefulness, that are essential pillars of acceptance models such as TAM (technology acceptance model). However, it should be investigated. Many studies have been carried out to research the issues of technology acceptance in different cultures, especially the western culture. Arabic culture lacks these types of studies with few publications in this field. This paper introduces a new biometric interface for ATM machines. This interface depends on a promising biometrics which is odour. To discover the acceptance of this biometrics, we distributed a questionnaire via a web site and called for participation in the Arab Area and found that most respondents would accept to use odour.

  18. A rule-based stemmer for Arabic Gulf dialect

    Directory of Open Access Journals (Sweden)

    Belal Abuata

    2015-04-01

    Full Text Available Arabic dialects arewidely used from many years ago instead of Modern Standard Arabic language in many fields. The presence of dialects in any language is a big challenge. Dialects add a new set of variational dimensions in some fields like natural language processing, information retrieval and even in Arabic chatting between different Arab nationals. Spoken dialects have no standard morphological, phonological and lexical like Modern Standard Arabic. Hence, the objective of this paper is to describe a procedure or algorithm by which a stem for the Arabian Gulf dialect can be defined. The algorithm is rule based. Special rules are created to remove the suffixes and prefixes of the dialect words. Also, the algorithm applies rules related to the word size and the relation between adjacent letters. The algorithm was tested for a number of words and given a good correct stem ratio. The algorithm is also compared with two Modern Standard Arabic algorithms. The results showed that Modern Standard Arabic stemmers performed poorly with Arabic Gulf dialect and our algorithm performed poorly when applied for Modern Standard Arabic words.

    To explore some of the main methodological challenges faced by interviewers in Arab settings, particularly during interviews with psychiatric nurses. Interviews are a tool used commonly in qualitative research. However, the cultural norms and practices of interviewees must be considered to ensure that an appropriate interviewing style is used, a good interviewee-interviewer relationship formed and consent for participation obtained sensitively. A study to explore the nature of psychiatric nurses' practices that used unstructured interviews. This is a methodology paper that discusses a personal experience of addressing many challenges that are specific to qualitative interviewing in Arab settings, supported by literature on the topic. Suggestions for improving the interview process to make it more culturally sensitive are provided and recommendations for future research are made. Openness, flexibility and a reflexive approach by the researcher can help manage challenges in Arab settings. Researchers should allow themselves to understand the cultural elements of a population to adapt interviewing methods with the aim of generating high quality qualitative research.

    When traveling in a region where the local language is not written using a "Roman alphabet," translating written text (e.g., documents, road signs, or placards) is a particularly difficult problem since the text cannot be easily entered into a translation device or searched using a dictionary. To address this problem, we are developing the "Rosetta Phone," a handheld device (e.g., PDA or mobile telephone) capable of acquiring an image of the text, locating the region (word) of interest within the image, and producing both an audio and a visual English interpretation of the text. This paper presents a system targeted for interpreting words written in Arabic script. The goal of this work is to develop an autonomous, segmentation-free Arabic phrase recognizer, with computational complexity low enough to deploy on a mobile device. A prototype of the proposed system has been deployed on an iPhone with a suitable user interface. The system was tested on a number of noisy images, in addition to the images acquired from the iPhone's camera. It identifies Arabic words or phrases by extracting appropriate features and assigning "codewords" to each word or phrase. On a dictionary of 5,000 words, the system uniquely mapped (word-image to codeword) 99.9% of the words. The system has a 82% recognition accuracy on images of words captured using the iPhone's built-in camera.

  7. Health Care, the Arab Spring and After

    Full Text Available This study analyzes the effect of health care on Middle Eastern countries on the eve of and soon after the Arab Spring. It posits that countries that were most stable were the healthiest ones; countries which underwent revolutions were the unhealthiest ones; whereas countries that settled for reforms were moderate in health. It presents a hypothesis, the Inverted Funnel Model Hypothesis, that states that as the level of health care of a country rises so does its stability, which in turn leads to better health care as if down an inverted funnel to hypothetical maximums of both health care and stability. To test the hypothesis both quantitative and qualitative methods are used. The quantitative part involves first of all compiling seven health indicators based on the World Health Organization Annual Reports on twelve individual countries, for a period of five years preceding the Arab Spring’s onset in 2011 and in the immediate aftermath of 2011, and, second of all running correlations with political stability of each country, grouped in a three-way typology of countries. This is supplemented by a qualitative part which analyzes the health perceptions and demands of Arab Spring protesters in search of social justice.

  8. Islamophobia and Arab and Muslim Women's Activism

    Full Text Available The aim of this article is to compare women’s activism in Diaspora communities in Muslim majority countries, such as Iran, with some of the experiences of women activists in Western counties such as Australia. This is by no means a definitive account of Arab and Muslim women’s activism in either country but an attempt to raise some questions and provide a framework in order to understand some of the issues facing Arab and Muslim activists today. I believe that it is important to look at these issues in a way that is contextualized in terms of the material circumstances in which women living in Diaspora communities find themselves. In doing so, I hope to reveal the complexity and dynamism of women’s activism and to take on critically, Orientalist, essentialist and racist arguments regarding the nature of Arab and Muslim women’s role in opposing war and neo-liberalism and in the struggle for gender equality. As Edward Said argues, exile forces us to “see things not simply as they are, but as they have come to be that way. Look at situations as contingent, not as inevitable, look at them as a series of historical choices made by men and women, facts of society made by human beings not as natural or God-given, therefore unchangeable, permanent, irreversible.”

    Full Text Available How did Syria’s conflict interact with the broader wave of regional protest known as the Arab Spring? This article uses a unique, complete Twitter dataset of tweets including the word “Syria” in English or Arabic to empirically test how Syria’s conflict was discussed online. The analysis shows a high level of interaction between Syria and other Arab countries through 2011. Other Arab countries experiencing popular protests (“Arab Spring countries” were referenced far more often in 2011 than were Syria’s immediate neighbors, while keyword analysis shows the framing of the conflict in terms of Syria’s “regime” aligned the conflict with other Arab uprisings. In 2012–2013 this changed sharply, with significantly fewer mentions of other Arab countries, particularly Arab Spring countries, more fundraising and political appeals across the Gulf, and growing Islamization. These findings offer one of the first empirical demonstrations of the integration and disintegration of a unified Arab discourse from 2011 to 2013, with significant implications for theories of the diffusion of protest and ideas.

    2011-01-01

    There is a lack of comparable data on physical activity, sedentary behavior, and dietary habits among Arab adolescents, which limits our understanding and interpretation of the relationship between obesity and lifestyle parameters. Therefore, we initiated the Arab Teens Lifestyle Study (ATLS). The ATLS is a multicenter collaborative project for assessing lifestyle habits of Arab adolescents. The objectives of the ATLS project were to investigate the prevalence rates for overweight and obesity, physical activity, sedentary activity and dietary habits among Arab adolescents, and to examine the interrelationships between these lifestyle variables. This paper reports on the objectives, design, methodology, and implications of the ATLS. The ATLS is a school-based cross-sectional study involving 9182 randomly selected secondary-school students (14-19 years) from major Arab cities, using a multistage stratified sampling technique. The participating Arab cities included Riyadh, Jeddah, and Al-Khobar (Saudi Arabia), Bahrain, Dubai (United Arab Emirates), Kuwait, Amman (Jordan), Mosel (Iraq), Muscat (Oman), Tunisia (Tunisia) and Kenitra (Morocco). Measured variables included anthropometric measurements, physical activity, sedentary behavior, sleep duration, and dietary habits. The ATLS project will provide a unique opportunity to collect and analyze important lifestyle information from Arab adolescents using standardized procedures. This is the first time a collaborative Arab project will simultaneously assess broad lifestyle variables in a large sample of adolescents from numerous urbanized Arab regions. This joint research project will supply us with comprehensive and recent data on physical activity/inactivity and eating habits of Arab adolescents relative to obesity. Such invaluable lifestyle-related data are crucial for developing public health policies and regional strategies for health promotion and disease prevention.

    The north African country of Tunisia (632,387 square miles) consists largely of desert, with some rich farmlands and a rocky transitional zone. Despite the government's family planning efforts, the population grew from 5.6 million in 1975, to 7.2 million in 1985, and, with its 2.4% annual growth rate, is projected to reach 8.1 million by 1990. Tunisia's rural population decreased to 46% in 1985 as workers and their families moved into urban areas. 98% of the population is Arab-Berber; Arabic and French are the offical languages. The age-sex distribution is typical of developing countries; the median age has increased from 16.8 years in 1966 to 19.5 in 1950 and persons over age 60 have increased from 5.1% in 1956 to 6.7% in 1980. Tunisian families average 5.7 persons in rural areas, and 5.4 persons in urban one. Marriages are declining, polygamy is outlawed, and divorce, once easy, is more difficult and declining. At independence in 1956, only 15% of Tunisians were literate, now 85-90% of primary school age children are enrolled and literacy had risen to 53% in 1980. Women, once heavily veiled, now have full rights and access to education. More than 60 thousand new workers compete for the 40,000 new job openings each year. An estimated 7000 laborers found work in Europe in 1984. Women composed only 11% of the 1975 work force, but by 1980, held 20% of jobs, although they were mainly low paying positions. In 1980, 35% of the laborers worked in agriculture, 19% in industry, 17% in service industries, and 10% in construction. Agriculture and tourism have declined in recent years, contributing to social unrest, currency decline, and inflated wages and consumer prices.

    The present study assessed the relations between reading anxiety, classroom anxiety, language motivation, and readers' self-perception for a sample of Arab-American students in Arabic classes. The effects of sex, grade, and years studying Arabic on academic achievement were examined as well. Measures were administered to 118 middle school students (56 boys, 62 girls; M age = 13.0 yr., SD = 0.8), and teachers reported academic grades in Arabic. Reading anxiety was significantly correlated with classroom anxiety and reader self-perception. Classroom anxiety scores were significantly correlated with motivation and reader self-perception. Significant positive correlations were found between language motivation and reader self-perception scores, and between years studying Arabic and reader self-perception scores. Boys in the second year of Arabic had significantly lower classroom anxiety than girls, and students in Grade 7 had higher reader self-perception than those in Grade 8. Classroom anxiety, language motivation, and reader self-perception significantly predicted Arabic achievement. Pedagogical implications are discussed.

  6. “We are Arabs:” The Embodiment of Virginity Through Arab and Arab American Women’s Lived Experiences

    2015-01-01

    Virginity is part of our existence in the world as embodied sexual subjects. While many meanings are associated with virginity, in most of the Arab world virginity relates to the presence of a hymen and extends to encompass the honor of the Arab community, and virginity loss commonly relate to first vaginal intercourse. This study explored the meanings of virginity from the perspectives of Arab and Arab American women. A qualitative phenomenological approach, informed by the philosophy of Maurice Merleau-Ponty, was used to conduct in-depth interviews with ten women. We identified one over-arching theme Virginity as Identity, and two major themes Embodiment of Virginity and “We are Arabs.” To reach an embodied virginity, participants went through a disembodied virginity process, reflecting society’s perceptions and values of virginity related to anatomical presence of a hymen and society’s honor. “We are Arabs” describes the ways women identified with the Arab ethnic identity as a shared overall identification, but differed from one lived experience to another, and influenced how participants embodied virginity. Our participants provided a better understanding of the diverse meanings of virginity that move beyond the binary of virginity and virginity loss, and into a spectrum of embodied meanings. Findings suggest the need for future research around sexuality in Arab Americans with attention to socio-political contexts in order to understand the nature and context of sexual initiation and its impact on sexual behaviors and well-being.

    Full Text Available Abstract Background The health authorities of Niger have implemented several malaria prevention and control programmes in recent years. These interventions broadly follow WHO guidelines and international recommendations and are based on interventions that have proved successful in other parts of Africa. Most performance indicators are satisfactory but, paradoxically, despite the mobilization of considerable human and financial resources, the malaria-fighting programme in Niger seems to have stalled, as it has not yet yielded the expected significant decrease in malaria burden. Indeed, the number of malaria cases reported by the National Health Information System has actually increased by a factor of five over the last decade, from about 600,000 in 2000 to about 3,000,000 in 2010. One of the weaknesses of the national reporting system is that the recording of malaria cases is still based on a presumptive diagnosis approach, which overestimates malaria incidence. Methods An extensive nationwide survey was carried out to determine by microscopy and RDT testing, the proportion of febrile patients consulting at health facilities for suspected malaria actually suffering from the disease, as a means of assessing the magnitude of this problem and obtaining a better estimate of malaria morbidity in Niger. Results In total, 12,576 febrile patients were included in this study; 57% of the slides analysed were positive for the malaria parasite during the rainy season, when transmission rates are high, and 9% of the slides analysed were positive during the dry season, when transmission rates are lower. The replacement of microscopy methods by rapid diagnostic tests resulted in an even lower rate of confirmation, with only 42% of cases testing positive during the rainy season, and 4% during the dry season. Fever alone has a low predictive value, with a low specificity and sensitivity. These data highlight the absolute necessity of confirming all reported

    Full Text Available Background: Helleborus niger L (Ranunculaceae is used Ayurvedic and Unani systems and other herbal medicine systems. The roots of H. niger have a good medicinal value. Aims: To conduct a pharmacognostical and phytochemical study of H. niger. Materials and Methods: The pharmacognostical studies on roots including parameters such as taxonomical, macroscopic, microscopic characters, physico-chemical, ultra-violet analysis and phytochemical studies are established. Results: Macroscopically, the roots are brownish-black in colour, cylindrical in shape, feeble odour, slightly acrid taste with irregularly branched. Microscopically the root showed the presence of epidermis, air-chambers, fissure periderm, periderm, inner cortex, pith, phloem, xylem, vessels and xylem vessels. Microscopic examination of the powder showed the presence of parenchyma cells, parenchyma mass, periderm, cell inclusion, laticifer, lateral wall pith, perforation, xylem bundle and xylem elements. Ultra-violet and ordinary light analyses with different reagents were conducted to identify the drug in powder form. Physico-chemical evaluation established, Ash values - Total, acid insoluble, water soluble and sulphated ash values were 7.3%, 4.1%, 3.7% and 5.2%, respectively. Extractive values - Alcohol soluble, water soluble and ether soluble extractive values were 22.8%, 7.4% and 5.6%, respectively. Loss on drying was 3.3%. Preliminary phytochemical screening showed the presence of carbohydrate, glycoside, saponins, flavonoid, phytosterols, tannins and phenolic compounds. Conclusions: The results of the study can serve as a valuable resource of pharmacognostic and phytochemical information. This will serve as appropriate, standards for discovery of this plant material in future investigations and applications and also contribute towards establishing pharmacopoeial standards.

    1995-12-31

    It can be difficult to obtain reliable rheological data for filamentous fermentation broths using conventional instruments. One common approach is to measure the torque drawn by an impeller rotating in the suspension. Many previous workers have assumed that the applicable shear rate in such a device is related to the impeller speed by a fluid-independent constant determined by calibration with Newtonian and non-Newtonian fluids. The rheology of Aspergillus niger broths have been characterized using the impeller viscometer approach. The changes in the broth rheology were measured, and used to interpret the growth of biomass and the evolution of the microorganism morphology.

    1999-01-01

    River erosion processes in the Niger Delta and the effectiveness of locally applied remedial measures is appraised, using information on channel geometry, flow velocity distribution, soil type, stratification, bank height and steepness, state of compaction, together with pool level variation in river channels. High flow velocity and bank height were identified as the major erosion causative factors. Local responses towards erosion mitigation have involved structural methods to varying degree of success. River training has been recommended as a long - term regional approach to mitigate river bank erosion. However, in the short -term revetments, concrete and sheets piles may be applied cautiously

    Full Text Available In Malaysia, Arabic language is spoken, and commonly used among the Malays. Malays use Arabic in their daily life, such as during performing worship. Hence, in this paper, some of the Arabic vowels attributes are investigated, analyzed and initial findings are presented based on tokens articulated by Malay speakers as we can consider the spoken Arabic by Malays as one of the Arabic dialects. It is known that in Arabic language there are 28 consonants and 6 main vowels. Firstly, the duration, variability, and overlapping attributes are highlighted based on syllables of Consonant–Vowel with each syllable representing every Arabic consonant with the corresponding vowels. Next, the dispersion of each vowel is examined to be compared with each other along with the variability among vowels that may cause overlapping between vowels in the vowel-space. Results showed that the vowel overlapping occurred between short vowels and their long counterpart vowels. Furthermore, an investigation of the Arabic vowel duration is addressed as well, and duration analysis for all the vowels is discussed, followed by the analysis for each vowel separately. In addition, a comparison between long and short vowels is presented as well as comparison between high and low vowel is carried out.

    AlHagbani, Eman Saad; Khan, Muhammad Badruddin

    2016-07-01

    The future information systems are expected to be more intelligent and will take human queries in natural language as input and answer them promptly. To develop a chatbot or a computer program that can chat with humans in realistic manner to extent that human get impressions that he/she is talking with other human is a challenging task. To make such chatbots, different technologies will work together ranging from artificial intelligence to development of semantic resources. Sophisticated chatbots are developed to perform conversation in number of languages. Arabic chatbots can be helpful in automating many operations and serve people who only know Arabic language. However, the technology for Arabic language is still in its infancy stage due to some challenges surrounding the Arabic language. This paper offers an overview of the chatbot application and the several obstacles and challenges that need to be resolved to develop an effective Arabic chatbot.

  6. Naming to empower: lesbianism in the Arab Islamicate world today.

    Amer, Sahar

    2012-01-01

    After a brief review of the proliferation of newly coined Arabic words to speak about LGBTQIA (lesbian, gay, bisexual, transgender, queer, intersex, and ally) identities, this article interrogates the facile imitation of Western labels and questions their usefulness in the context of Arab societies and cultures. It demonstrates that the assumptions that underlie the creation of new wordlists overlook and ultimately erase the very rich tradition on alternative sexual practices that has been prominent in the Islamicate world at least since the ninth century. Salvaging this tradition and its accompanying terminology on homosexuality challenges the claim that homosexuality is a Western importation, and renders the recourse to English categories superfluous. Moreover, uncovering the forgotten Arabic cultural material on alternative sexualities offers contemporary Arab gays and lesbians a rich and empowering indigenous heritage, as well as home-grown modes of resistance that are poised to challenge homophobic attitudes and policies in the Arab world, and the hegemony of Western sexual and cultural imperialism.

  7. Working for change in the Arab world. Advocacy for reproductive health: Arab world.

    Science.gov (United States)

    Hamand, J

    1996-01-01

    The International Conference on Population and Development (ICPD) revealed that within the Arab world there are special difficulties with regard to family planning (FP) and the status of women. There is general social opposition to women's empowerment and employment outside the home, which FP associations have to tackle. At the Cairo ICPD in 1994 the Vatican and Islamic fundamentalists formed a holy alliance against undesirable Western ideas. Eventually most Arab governments became convinced about the need for the program of action. A regional conference was also held in January 1996 on this agenda organized by the IPPF Arab World Region in Cairo to implement the program of action with the participation of 140 representatives. The question of population at the Cairo meeting was linked to economic and social development leading up to the women's conference in Beijing in 1995. At the 1996 implementation meeting the unmet need for reproductive health services was voiced along with the need for solid research in this area. FP has a vital role in social development and in combating poverty. The implementation of IPPF's Vision 2000 strategic plan also contributes to the implementation of the ICPD program of action, which deals with sex education, unsafe abortion, marginalized groups, and women's empowerment. Even Islam has come to support responsible FP for the sake of the well-being of the family. The Grand Mufti of Egypt pronounced his support for FP for health and socioeconomic reasons, for the education of girls, and for equality with men. In Arab countries the outstanding problems are early marriage, female genital mutilation, sexually transmitted diseases (STDs) and HIV, unwanted pregnancy, unsafe abortion, and ignorance about reproduction. Listening to young people, funding restrictions hampering progress, and an advocacy group of prominent leaders, and the formation of an Arab parliamentarians group on FP were other high points.

  11. Stylistic Features of Comment in Arabic Blogosphere

    2017-11-01

    Full Text Available One of the most important issues in the study of the functioning of the Internet language is the definition of the features of each Internet genre presented in online communication, taking into account the linguocultural features of the language in question. This paper studies the genre of the Internet comments of the Arabic-speaking blogosphere and reveals its stylistic features. The most common goal of the comment is gratitude, followed by praise. We created a corpus of comments from blogs of various subjects, and then conducted the tagging, having identified the group to which we attributed a comment, depending on the subject and the communicative goal. With the help of the Lexico 3 software, the most frequent lexical units were identified, the lexical features of the comments were described, the main one being the widespread use of religionyms, and the relationship between the blog subject and the stylistic characteristics of communication was revealed. The article traces the correlation between the literary and colloquial functional style in the comments, and also draws a conclusion that the comments are of a conversational, informal character. The main devices of expressiveness that are characteristic for both network and pre-network communication were revealed, and the tendency of the analysts to observe in the comments a stable three-part composition (greeting, message, final formula. The influence of traditional Arabic rhetoric, as well as the epistolary genre, was preserved. The results of the paper can be used when studying other genres of Internet communication in Arabic and in comparative studies to create the linguistic software.

  12. Water ethics perspectives in the Arab Region

    International Nuclear Information System (INIS)

    Al-Awar, F.; Abdulrazzak, M. Jameel; Al-Weshah, R.

    2006-01-01

    Water ethics has only recently emerged in academic and development arenas as an independent field of professional discussion. Concerns over water conservation and adequate access to basic needs of water and sanitation pose a difficult ethical dilemma that should be addressed based on societal and ethical frame works. Issues such as water allocation and pricing, privatization of various water services and efficient water management need to be contested within an ethical framework according to principles of equity and social justice. This paper presents the basic concepts of water ethics, as well as water ethics perspectives and applications within the framework of integrated water resources management (IWRM) in the Arab Region, which suffers from one of the fastest growing water deficits in the world. The deteriorating status of the water resources situation in Arab Region is no longer tolerable due to the high costs in terms of negative environmental consequences and deteriorating livelihoods of poor populations associated with lack of access to clean water and sanitation. Nevertheless, most of the national efforts for IWRM implementation in the Region have been dominated by neo-liberal economic policies stressing privatization of various water services; cost recovery through different pricing and tariffication schemes; as well as sectoral water (re)allocation. However, many negative impacts due to the shift to neo-liberal market-led economies have been surfaced throughout the developing world in the past decade and a half, especially with respect to the increased levels of poverty and worsening environmental degradation. It is, therefore, critical to adopt IWRM approaches in the region within an ethical framework that takes full consideration of all social implications regarding the poor, and that could be used as a means to achieve water-related international goals of poverty reduction. Finally, the paper also shows that there is no contradiction between Islamic

    To examine the prevalence of diabetes and glucose intolerance by age and sex in the Arab-American community of Dearborn, Michigan. Participants were randomly selected adult Arab Americans, 20-75 years of age, from randomly selected households in Dearborn, Michigan. Demographic and anthropometric data were recorded. Glucose tolerance was assessed with 2-h 75-g oral glucose tolerance tests and classified according to 1997 American Diabetes Association and 1998 World Health Organization criteria. A total of 626 eligible adults were selected, and 542 participated (87% response rate). Because prevalence increases with age and the overall response rate for women (328/352; 93%) was higher than that for men (214/274; 78%), prevalence rates were adjusted for age and sex. The overall prevalence of diabetes was 15.5% (95% CI 12.2-18.7%) in women and 20.1% (15.0-25.2%) in men (P = 0.13). The prevalence of previously diagnosed diabetes was similar to that of undiagnosed diabetes. Impaired glucose tolerance (IGT) and/or impaired fasting glucose (IFG) were present in 16.8% (12.8-20.8%) of women and 29.7% (23.4-35.9%) of men (P = 0.0007). The combined rates of glucose intolerance (diabetes, IGT, and IFG) were 32.3% (27.8-36.7%) for women and 49.8% (43.1-56.4%) for men (P women. As expected, subjects with diabetes or IGT/IFG were older and had greater BMI and waist-to-hip ratios than subjects with normal glucose tolerance. The prevalence of diabetes and glucose intolerance is extremely high among adult Arab Americans in Michigan and represents a major clinical and public health problem. Community-based intervention programs to prevent and treat diabetes are urgently needed.

    Since late 2010, the Arab world has entered a tumultuous period of change, with populations demanding more inclusive and accountable government. The region is characterised by weak political institutions, which exclude large proportions of their populations from political representation and government services. Building on work in political science and economics, we assess the extent to which the quality of governance, or the extent of electoral democracy, relates to adult, infant, and maternal mortality, and to the perceived accessibility and improvement of health services. We compiled a dataset from the World Bank, WHO, Institute for Health Metrics and Evaluation, Arab Barometer Survey, and other sources to measure changes in demographics, health status, and governance in the Arab World from 1980 to 2010. We suggest an association between more effective government and average reductions in mortality in this period; however, there does not seem to be any relation between the extent of democracy and mortality reductions. The movements for changing governance in the region threaten access to services in the short term, forcing migration and increasing the vulnerability of some populations. In view of the patterns observed in the available data, and the published literature, we suggest that efforts to improve government effectiveness and to reduce corruption are more plausibly linked to population health improvements than are efforts to democratise. However, these patterns are based on restricted mortality data, leaving out subjective health metrics, quality of life, and disease-specific data. To better guide efforts to transform political and economic institutions, more data are needed for health-care access, health-care quality, health status, and access to services of marginalised groups.

    2013-01-01

    Full Text Available This article reveals, by studying correlative relationships between US regime support and regime properties, that the US foreign policy in the Middle East has traditionally helped governments to limit the political participation of Islamists, communists, enemies of Israel and populations that could be hostile to the US oil interests. This way the US economic and strategic security interests have contributed to human insecurity in the region. With the exception of the last interest, the US has relaxed its support for repression of the above-mentioned groups. This seems to be one of the international factors that made the Arab Spring possible.

  20. Molecular Dynamics Approach in Designing Thermostable Aspergillus niger Xylanase

    Malau, N. D.; Sianturi, M.

    2017-03-01

    Molecular dynamics methods we have applied as a tool in designing thermostable Aspergillus niger Xylanase, by examining Root Mean Square Deviation (RMSD) and The Stability of the Secondary Structure of enzymes structure at its optimum temperature and compare with its high temperature behavior. As RMSD represents structural fluctuation at a particular temperature, a better understanding of this factor will suggest approaches to bioengineer these enzymes to enhance their thermostability. In this work molecular dynamic simulations of Aspergillus niger xylanase (ANX) have been carried at 400K (optimum catalytic temperature) for 2.5 ns and 500K (ANX reported inactive temperature) for 2.5 ns. Analysis have shown that the Root Mean Square Deviation (RMSD) significant increase at higher temperatures compared at optimum temperature and some of the secondary structures of ANX that have been damaged at high temperature. Structural analysis revealed that the fluctuations of the α-helix and β-sheet regions are larger at higher temperatures compared to the fluctuations at optimum temperature.
