We introduce a new jet clustering algorithm named SIFT (scale-invariant filtered tree) that maintains the resolution of substructure for collimated decay products at large boosts. The scale-invariant measure combines properties ${k}_{\mathrm{T}}$ and anti-${k}_{\mathrm{T}}$ by preferring early association soft radiation with resilient hard axis, while avoiding specification fixed cone size. Int...

Mujāhid b. Jabr (d. 103/721) is one of the prominent scholars tābiʿīn generation. There consensus among that he was a reciter (qāriʾ), jurist (faqīh), and trustworthy (thiqa) scholar. A disciple Ibn ʿAbbās 68/687-688), particularly known for his contributions to science Qur’an exegesis (tafsīr), therefore has been referred by such appellations as al-Imām leader reciters exegetes (shaykh al-qurr...

In considering how development studies can best be taught at the postgraduate level, one question which arises at a very early stage of curriculum planning is whether the subject has an intellectual core.1 There are at least a hundred different ways in which one might design a postgraduate course in the subject. But these hundred or so designs can be divided into two main groups. One group foll...

The presented work deals with synthesis and isolation of constitutional isomers of triazolo-fused azaphthalocyanines. Distribution of the isomers did not follow the statistical calculations due to steric effects of the substituents preferring the least sterically stressed C(4h) isomer.

In higher plants, the shoot and the root generally show negative and positive gravitropism, respectively. To elucidate the molecular mechanisms involved in gravitropism, we have isolated many shoot gravitropism mutants in Arabidopsis. The sgr2 and zig/sgr4 mutants exhibited abnormal gravitropism in both inflorescence stems and hypocotyls. These genes probably are involved in the early step(s) o...

Infertility affects 20% of couples in Nigeria. Assisted reproductive techniques (ART) offered in Nigeria include in-vitro fertilization (IVF), gamete donation and surrogacy. This cross-sectional questionnaire study aimed at assessing the acceptability of ART to women seeking infertility treatment at the University College Hospital, Ibadan, Nigeria. Of the 307 respondents, 58.3% were aware of IV...

Aims and method To explore the current salience of 'brain fag' as a nosological, diagnostic and clinical construct in modern West African psychiatry. A semi-structured questionnaire and vignette based on classical symptoms of brain fag syndrome were used to explore current knowledge, explanatory models and practice among Nigerian psychiatrists. Results Of 102 psychiatrists who responded, 98% re...

the verses of the qur’ān apparently talk about the six-day creation of the heavens and the earth but the new science views the process of the formation of heavenly bodies and the earth in a longer time span and does not approve the formation of the universe in a period of a few days. thus, many of the contemporary qur’ān researchers have withdrawn from the formalistic and generally accepted (ma...

criticism of public extension services has resulted in various countries seeking alternative approaches for provision of these services. in all these approaches, extension personnel are the key factors to the success of the implementation. today, agricultural extension services in turkey bear the responsibility of the ministry of food, agriculture and livestock. a number of non-public extension...
