The Chinese jujube (Ziziphus jujuba Mill.), originating from China, with a history of over 4000 years, is one of the major fruit crops cultivated in China and on important areas in Central Asia, India, Iran, the Middle East etc. The high resistances to drought, salty soils and similar climate to that of China recommend this fruit tree as a valuable crop, especially in the context of climate changes and extended desertification. Chinese jujube has a high tolerance to pests and disease, being suitable for organic farming. The lack of divulgative papers on jujube true nutritional, medicinal and economic value, makes it still unknown for the great part of Romanian and European consumers, intensive advertising campaign is needed. The aim of this review is to highlight the requirements of the Chinese jujube (Ziziphus jujuba Mill.) in regards to the soil, water, climate as well as its high nutritional and medicinal values.

Chinese jujube (Ziziphus jujubaMill. [Rhamnaceae]), native to China, is a major dried fruit crop in Asia. Although many simple sequence repeat (SSR) markers are available for phylogenetic analysis of jujube cultivars, few of these are validated on the level of jujube populations. In this study, we first examined the abundance of jujube SSRs with repeated unit lengths of 1–6 base pairs, and compared their distribution with those inArabidopsis thaliana. We identified 280,596 SSRs in the assembled genome of jujube. The density of SSRs in jujube was 872.60 loci/Mb, which was much higher than inA. thaliana(221.78 loci/Mb). (A+ T)-rich repeats were dominant in the jujube genome. We then randomly selected 100 SSRs in the jujube genome with long repeats and used them to successfully design 70 primer pairs. After screening using a series of criteria, a set of 20 fluorescently labeled primer pairs was further selected and screened for polymorphisms among three jujube populations. The average number of alleles per locus was 12.8. Among the three populations, mean observed and expected heterozygosities ranged from 0.858 to 0.967 and 0.578 to 0.844, respectively. After testing in three populations, all SSRs loci were in Hardy-Weinberg equilibrium (HWE) in at least one population. Finally, removing high null allele frequency loci and linked loci, a set of 17 unlinked loci was in HWE. These markers will facilitate the study of jujube genetic structure and help elucidate the evolutionary history of this important fruit crop.

This book presents a history of nineteenth century metaphysics in Britain, providing close textual readings of the key contributions to First Philosophy made by the key philosophers of the period (such as Hamilton, Mansel, Spencer, Mill, and Bradley) as well as some lesser known figures (such as Bain, Clifford, Shadworth Hodgson, Ferrier, and John Grote). The story focuses on the elaboration of, and differing reactions to, the concept of the unknowable or unconditioned, first developed by Sir William Hamilton in the 1829. The idea of an ultimate but unknowable way that things really are in themselves may be seen as supplying a narrative arc that runs right through the metaphysical systems of the period in question as, relative to this concept, these thought schemes may be divided into three broad groups which were roughly consecutive in their emergence but also overlapping as they continued to develop. In the first instance there were the doctrines of the agnostics who further progressed Hamilton’s basic idea that fundamental reality lies for the great part beyond our cognitive reach, but these philosophies were followed, immediately by those of the empiricists and, in the last third of the century by those of the idealists, both of whom—albeit in profoundly different ways—reacted against the epistemic pessimism of the agnostics. By presenting, interpreting, criticizing and connecting together their various contrasting ideas this book explains how these three traditions developed and interacted with one another to comprise the history of metaphysics in Victorian Britain.

Twenty years ago, the field of ancient DNA was launched with the publication of two short mitochondrial (mt) DNA sequences from a single quagga ( Equus quagga ) museum skin, an extinct South African equid ( Higuchi et al . 1984 Nature 312 , 282–284). This was the first extinct species from which genetic information was retrieved. The DNA sequences of the quagga showed that it was more closely related to zebras than to horses. However, quagga evolutionary history is far from clear. We have isolated DNA from eight quaggas and a plains zebra (subspecies or phenotype Equus burchelli burchelli ). We show that the quagga displayed little genetic diversity and very recently diverged from the plains zebra, probably during the penultimate glacial maximum. This emphasizes the importance of Pleistocene climate changes for phylogeographic patterns in African as well as Holarctic fauna.

The Lebanese singer Fairuz is one of the most popular and critically acclaimed performers in the history of Arab musical arts. Born Nuhad Haddad in 1935, Fairuz attained extraordinary success, in great part, through her cultivation of an exceptional command of the voice, her development of a deep individual artistry, and her solid rooting in the performance practices of Lebanese and Arab art and popular song. From early in her career, this achievement was in collaboration with the Rahbani family of composer-poets. Assi Rahbani (b. 1923–d. 1986) and Mansour Rahbani (b. 1925–d. 2009) were siblings who worked together as the duo known as the Rahbani Brothers. Fairuz and the Rahbani Brothers met at the Lebanese Radio Station, where she took her professional name, and they began a collaboration there that gave rise to their first international hit in 1952. Occasionally, younger brother Elias Rahbani (b. 1938–d. 2021) joined in the composing as well. Following the marriage of Fairuz and Assi in 1954, Fairuz gave birth to their first child, Ziad Rahbani (b. 1956), who was raised in the presence of some of the most accomplished artists from across Arab society and who similarly showed a remarkable aptitude for musical arts early in life. Following the death of Assi in 1986, Ziad became the primary composer for Fairuz, after which her lyrical and musical style to some extent began increasingly to reflect more of the sensibilities of a younger generation. Since their beginnings, the Fairuz-Rahbani team has changed with the times and given rise to a prodigious artistic output that has included the production of operettas, musical theater sketches, musical films, and over a hundred record albums. Thematically, the wide-ranging repertoire has sometimes addressed universalistic spiritual matters with references to God, eternity, prayer, and other mystical subjects. The artists also have presented material of more expressly religious character that mentions churches, mosques, and houses of worship; that covers esteemed geographical locales, such as Jerusalem and Mecca; and that presents traditional repertoire like Good Friday chanting and Christmas carols. While Fairuz and the Rahbani composers are Christians, their repertoire has appealed across society irrespective of religious and sectarian affiliation. In the process, Fairuz has become a multifaceted icon to listeners from diverse backgrounds in Lebanon, throughout the eastern Mediterranean, across Arab society, and in the diaspora. As for transliteration of the names from Arabic into Latin script, “Rahbani” is fairly consistent, but “Rahbany” also occurs. The plural (i.e., three or more) is “Rahabina” and also is found in the forms “Rahbaniyun” and “Rahbaniyin” while in English it appears as “Rahbanis” as well. While the duo of the Rahbani Brothers has been consistently translated into English in this way, the Arabic form is either “al-Akhawan Rahbani” or “al-Akhawayn Rahbani” (i.e., the two Rahbani Brothers). “Fairuz,” which means “turquoise” in Arabic, has numerous variants in transliteration stemming, in part, from the various possibilities for each syllable of the name (e.g., Fairouz, Fayruz, etc.), but some degree of standardization has come, in part, from the use of this spelling by Voix de l’Orient, the record label that has produced the bulk of her recordings.

In the particular and peculiar case of the Booker Prize, regarded as the most prestigious literary award in the United Kingdom (as measured by economic value to the author and publisher, and total audience for the awards announcement), the cultural and economic valences of literary prizes collide with the imperial history of Britain, and its after-empire relationships to its former colonies. From its beginnings, the Booker prize has never been simply a British prize for writers in the United Kingdom. The Booker’s reach into the Commonwealth of Nations, a loose cultural and economic alliance of the United Kingdom and former British colonies, challenges the very constitution of the category of post-imperial British literature. With a history of winners from India, South Africa, New Zealand, and Nigeria, among many other former British colonies, the Booker presents itself as a value arbitrating mechanism for a majority of the English-speaking world. Indeed, the Booker has maintained a reputation for bringing writers from postcolonial nations to the attention of a British audience increasingly hungry for a global, cosmopolitan literature, especially one easily available via the lingua franca of English. Whether and how the prize winners avoid the twin colonial pitfalls of ownership by and debt to an English patron is the subject of a great deal of criticism on the Booker, and to understand the prize as a gatekeeper and tastemaker for the loose, baggy canon of British or even global Anglophone literature, there must be a reckoning with the history of the prize, its multiplication into several prizes under one umbrella category, and the form and substance of the novels that have taken the prize since 1969.

This paper examines how the past of desert landscapes has been interpreted since European explorers and scientists first encountered them. It charts the research that created the conceptual space within which archaeologists and Quaternarists now work. Studies from the 1840s–1960s created the notion of a ‘Great Australian Arid Period'. The 1960s studies of Lake Mungo and the Willandra Lakes by Jim Bowler revealed the cyclical nature of palaeolakes, that changed with climate changes in the Pleistocene, and the complexity of desert pasts. SLEADS and other researchers in the 1980s used thermoluminescence techniques that showed further complexities in desert lands beyond the Willandra particularly through new studies in the Strzelecki and Simpson Dunefields, Lake Eyre, Lake Woods and Lake Gregory. Australian deserts are varied and have very different histories. Far from ‘timeless lands', they have carried detailed information about long-term climate changes on continental scales.

This article examines the history of silkworm breeding, the role of silkworm breeding in the national economy of the Republic of Uzbekistan and the role of silkworm breeding in the development of the industry. This is because the interrelationship of traits of economic value is of great importance in selection and breeding work. The experiments were conducted in 2015-2017 at the Silk Research Institute of Uzbekistan. The life expectancy of the experimental butterflies was 10.9-12.8 days and the variability was 33.9-56.6%. The coefficient of variability indicates the degree of diversity in the population on this trait. Thus, it is clear from the results that the population of “Marvarid” and “Liniya 27” has the ability to carry out selection work on the sign of life expectancy of female butterflies.

The purpose of zakat to develop the social economic value of society is difficult to materialize if there is no active role of zakat managers (amil) who are required to be professional and innovative in managing zakat funds. The main function of the amil zakat institution lies in the activities of collecting, distributing, and utilizing zakat. The activity of collecting zakat in the history of Islam, is an activity or effort of amil in collecting zakat by picking up or taking from the place of amil. In addition to taking zakat, the amils who are in charge of taking zakat must also pray for those who pay zakat.This study aims to determine the implementation of productive zakat fund management and empowerment of the poor on zakat funds that are given by LAIZSNU Lamongan. By using the case study method, so as to be able to photograph how LAZISNU Lamongan's performance is in managing productive zakat funds . Lazisnu Lamongan has 3 zakat distribution programs, namely humanitarian, health and economic assistance. The mustahik empowerment program is included in the economic assistance program.
