Within a short span of time a number of economic blocs have emergedon the world horizon. In this race, all countriedeveloped, developingand underdeveloped-are included. Members of the North America FreeTrade Agreement (NAITA) and the European Economic Community(EEC) are primarily of the developed countries, while the EconomicCooperation Organization (ECO) and the Association of South EastAsian Nations (ASEAN) are of the developing and underdevelopedAsian countries.The developed countries are scrambling to create hegemonies throughthe General Agreement on Tariff and Trade (GATT). In these circumstances,economic cooperation among Muslim countries should be onthe top of their agenda.Muslim countries today constitute about one-third of the membershipof the United Nations. There are around 56 independentMuslim states with a population of around 800 million coveringabout 20 percent of the land area of the world.

Acephalic spermatozoa syndrome (ASS) is a rare but extremely severe type of teratozoospermia, defined by the presence of a majority of headless flagella and a minority of tail-less sperm heads in the ejaculate. Like the other severe monomorphic teratozoospermias, ASS has a strong genetic basis and is most often caused by bi-allelic variants in SUN5 (Sad1 and UNC84 domain-containing 5). Using whole exome sequencing (WES), we investigated a cohort of nine infertile subjects displaying ASS. These subjects were recruited in three centers located in France and Tunisia, but all originated from North Africa. Sperm from subjects carrying candidate genetic variants were subjected to immunofluorescence analysis and transmission electron microscopy. Moreover, fluorescent in situ hybridization (FISH) was performed on sperm nuclei to assess their chromosomal content. Variant filtering permitted us to identify the same SUN5 homozygous frameshift variant (c.211+1_211+2dup) in 7/9 individuals (78%). SUN5 encodes a protein localized on the posterior part of the nuclear envelope that is necessary for the attachment of the tail to the sperm head. Immunofluorescence assays performed on sperm cells from three mutated subjects revealed a total absence of SUN5, thus demonstrating the deleterious impact of the identified variant on protein expression. Transmission electron microscopy showed a conserved flagellar structure and a slightly decondensed chromatin. FISH did not highlight a higher rate of chromosome aneuploidy in spermatozoa from SUN5 patients compared to controls, indicating that intra-cytoplasmic sperm injection (ICSI) can be proposed for patients carrying the c.211+1_211+2dup variant. These results suggest that the identified SUN5 variant is the main cause of ASS in the North African population. Consequently, a simple and inexpensive genotyping of the 211+1_211+2dup variant could be beneficial for affected men of North African origin before resorting to more exhaustive genetic analyses.

Eighth Army

High rates of desertion and surrender during the battles in North Africa in the summer of 1942 were a major factor in Eighth Army’s poor combat performance. At the time, some suggested that these problems were symptomatic of a lack of courage or even of cowardice. There are two broad strands to the conceptualization of courage and cowardice. One focuses on the willingness of the person to fight; the other puts emphasis on how actions express an individual’s ability to cope with fear. Whichever conceptualization is used, high morale motivates the soldier to fight and shields the ordinary recruit from his fear, preventing it from overcoming him in battle. Where morale fails, the soldier is left demotivated and burdened with his terror and, therefore, and is therefore prone to desertion or surrender. Because it is extremely difficult to maintain morale at a continuously high level in an environment governed by chance and managed by humans, all soldiers can find themselves in situations where their actions may be judged as cowardly. Alternatively, if they are properly motivated to fight and prepared by the state and military to deal with the unavoidable fear of combat, all soldiers can be labelled courageous. Accordingly, emotive terms should be avoided when attempting to describe rationally explainable outcomes. The undoubtedly negative connotations attached to cowardice in battle and the positive ones attached to courage are, therefore, arguably unhelpful in understanding Eighth Army’s performance in the summer of 1942 and the human dimension in warfare more generally.

The topic of military settlements and the role of troops in the northern provinces of North Africa during the age of the Roman Empire has recently gained a strong interest in historical, archaeological, epigraphical, and economic studies. In particular, at Mauretania Tingitana (in the north-east area of modern-day Morocco), the presence of numerous military camps in the Early and Later Roman Empire has now been assessed. In this framework, the present work deals with the geophysical survey, by means of magnetometry, at the site of el Benian, where the largest military camp is located. In particular, the magnetic survey has highlighted the organization of the camp, almost totally unknown previously. The result of the magnetic survey has confirmed intense building activity over the centuries and made it possible to identify and characterize the structures typical of a military field.

AbstractWintertime precipitation is vital to the growth of glaciers in the northern hemisphere. We find a tripole mode of precipitation (PTM), with each pole of the mode extending zonally over the eastern hemisphere roughly between 30°W and 120°E, and the positive/negative/positive structure for its positive phase extending meridionally from the Arctic to the continental North Africa–Eurasia. The large-scale dynamics associated with the PTM is explored. The positive phase of the PTM is associated with the negative while eastward-shifted phase of the North Atlantic Oscillation (NAO) and a zonal band of positive SST anomaly in the tropics, together with a narrowed Hadley cell and weakened Ferrel cell. While being north-eastward tilted and separated from their North Africa-Eurasia counterpart in the climatological mean, the upper-tropospheric westerly jets over the east Pacific and north Atlantic become extending zonally and shifting southward and hence form a circumpolar subtropical jet as a whole by connecting with the westerly jets over the North Africa-Eurasia. The enhanced zonal winds over the north Atlantic promote more synoptic-scale transient eddies which are waveguided by the jet streams. The polar vortex weakens and cold air dips southward from the North Pole. Further diagnosis of the E-vectors suggests that transient eddies have a positive feedback on the weakening of Ferrel cell. Opposite features are associated with the negative phase of the PTM. The reconstructed time series using multiple linear regression on the NAO index and the tropical SST averaged over 20°S– 20°N, can explain 62.4% of the variance of the original the original precipitation time series.

Abstract This article aims at presenting ISIS expansion in North Africa in the first quarter of 2016, with its subsequent implication in the wider framework of Jihadist proliferation worldwide. It can be argued that, while losing real estate in the Middle East, ISIS has started a permanent search for extra-cellular matrices or an ongoing process of de- and reterritorialization. The allegiance and support pledged by other African-based terrorist groups or organizations such as Boko Haram, al-I’tisam of the Koran and Sunnah in Sudan, al-Huda Battalion in Maghreb of Islam, The Soldiers of the Caliphate, al-Ghurabaa, Djamaat Houmat ad-Da’wa as-Salafiya and al-Ansar Battalion in Algeria, Islamic Youth Shura Council, Islamic State Libya (Darnah), in Libya, Jamaat Ansar Bait al-Maqdis, Jund al-Khilafah and Mujahideen Shura Council in the Environs of Jerusalem in Egypt, Okba Ibn Nafaa Battalion, Mujahideen of Tunisia of Kairouan and Jund al-Khilafah in Tunisia and al-Shabaab Jubba Region Cell Bashir Abu Numan in Somalia is an alarming hypothesis of Jihadism reaching “the threshold of inevitability”- syntagm existent in the network theories of David Singh Grewal- turning a whole region, continent of even world into what Nassim Nicholas Taleb would call Extremistan.

The article considers a place and influence of Berber-speaking communities in each of five countries of the North Africa: Algeria, Morocco, Libya, Mauritania and Tunis.After gaining the independence, demands are growing in all these states to recognize cultural, regional, and sometimes political peculiarities of Berbers.The situation in every country is different due to local conditions and background of interactions of Amazigs (self-designation of Berber) with the Arab speaking majority, as well as their participation in political processes.The author investigates and discuss the impact of the Arab Spring on the rise of self-consciousness, solidarity and consolidation of Amazig minority. It is Berber, often European educated elite which usually expresses and propagates such conceptions and trends.

Abstract This article discusses The Met’s unpublished Dalāʾil al-khayrāt—2017.301—(MS New York, TMMA 2017.301), together with a group of comparable manuscripts. The earliest known dated manuscript within the corpus, it introduces several iconographic elements that are new to the Dalāʾil, and which compare with the traditions developing in the Mashriq and the Ottoman world in particular. The article discusses Dalāʾil production in seventeenth-century North Africa and its development in the Ottoman provinces, Tunisia, and/or Algeria. The manuscripts illustrate how an Ottoman visual apparatus—among which the theme of the holy sanctuaries at Mecca and Medina, appearing for the first time in MS New York, TMMA 2017.301—is established for Muhammadan devotion in Maghribī Dalāʾils. The manuscripts belong to the broader historic, social, and artistic contexts of Ottoman North Africa. Our analysis captures the complex dynamics of Ottomanization of the North African provinces of the Ottoman Empire, remaining strongly rooted in their local traditions, while engaging with Ottoman visual idioms.
