The effects of light intensity on seed germination and seedling growth of cassia fistula (linn.), enterolobium saman (jacq.) Prain ex king. And delonix
No full textThe present study investigated the effect of 100, 50 , and 25 % light intensities
on seed germination and early seedling development of Cassia fistula, Enterolobium
saman and Delonix regia. The experiment was carried out under temperature of 25°C
- 15°C day and night and 65 % relative humidity, in the greenhouse. One hundred
percent light intensity significantly produced the highest seed germination and
seedling growth of the three species for all growth characteristics measured. Fifty
percent light intensity treatment produced seed germination and seedling growth to
come in the second order and, sometimes, shared full light intensity treatment. The
growth characteristics of Delonix regia seedlings had almost the highest values
among species and in full light intensity treatment. Although Cassia fistula seedlings
had lower growth, in comparison with the other two species, however, they tolerated
low light intensity and had the highest survival and root growth.Corresponding Author:

Effects of pre-germination treatments and sowing depths upon germination potential of some Acacia species
No full textSeeds of Acacia farnesiana (L.) Willd., A. salicina Lindley, A.
nilotica (L.) Willd. ex Del., A. ehrenbergiana Hayne, A. seyal Del., A.
saligna (Labill.) H. L. Wendl. and A. tortilis (Forssk.) Hayne were
subjected to pre-germination treatment. This was either by soaking
seeds in water for 24 or 48 or 72 hours or by placing them in boiling
water and left them to cool to the room temperature. All seeds were
sowed either at 2 or 4 or 6-cm at soil. The higher germination
percentage for all Acacia species was obtained after boiling seeds in
water and at 2-cm sowing depth apart from A. ehrenbergiana. It
showed no response to boiling in water but had the best result with
soaking in water for 24h. The results of this study suggest that boiling
seeds of the investigated Acacia species in water is recommended with
sowing depth not deeper than 4 cm.Corresponding Author:

Performance of Leucaena leucocephala and Albizia lebbeck trees under low irrigation water in the field
No full textGrowth of Leucaena leucocephala and Albizia lebbeck trees was investigated under
low water supply in the field using a complete randomized block design at the
Research and Experiments Station of the College of Food Science and Agriculture,
Riyadh, Saudi Arabia. The trees were irrigated at either 160 (well water supply) or
500 mm (low water supply) of a class "A" evaporation-pan records for two years.
Differences were occurred between L. leucocephala and A. lebbeck trees across
irrigation treatments with greater values for L. leucocephala in most of the growth
characteristics measured. Comparing with L. leucocephala, leaves of A. lebbeck
comprises only small proportion of the total weight of tree while allocated equal
proportions to their branches and roots (41%).while L. leucocephala trees allocated
almost similar proportions to their branches, stem and roots (27-28%). Low water
supply decreased stem by 19.5% with stem diameter was unaffected. Leaf, branches,
stem, root and consequently total dry weight of the trees decreases by 42, 51.5, 45, 51
and 94% in low water supply. However, the performance of L. leucocephala and A.
lebbeck trees endured low irrigation conditions in terms of survival and maintaining
reasonable growth.Corresponding Author:

Rubaies of İbrahim Aczî kendî (The last 180 rubaies)
No full text1881-1965 yılları arasında Konya'da yaşayan İbrahim Aczî Kendî, Konya'nın XX. yüzyılda yetiştirdiği önemli şair, gazeteci, araştırmacı, yazar, mutasavvıf ve folklorculardandır. Konya'da öğretmenlik yapan İbrahim Aczî Kendî, Arapça ve Farsça öğrenerek kendini geliştirmiş, tasavvuf, edebiyat ve tarihle ilgili kitaplar hazırlamıştır. İbrahim Aczî Kendî'nin bizzat kendisinin kaleme aldığı, tek nüshası Yusuf Ağa Kütüphanesinde 10465/1 numara ile kayıtlı olan Devr-i Zaman adlı eseri, 360 Farsça rubâî ve bu rubâîlerin Osmanlı Türkçesiyle yazılmış açıklamalarından oluşmaktadır. Bu çalışmada İbrahim Aczî Kendî'nin hayatı incelenmiş, Devr-i Zaman adlı eserinde bulunan 360 rubâînin son 180 tanesi çalışılmıştır. Her bir rubâînin Farsça ana metinleri bilgisayar ortamına aktarılmış, bazen sadece tercüme, bazen de çeşitli açıklamalar içeren Osmanlı Türkçesiyle yazılan kısımlar ise latin harfleriyle aktarılmıştır. İbrahim Aczî Kendî, bu çalışmada ele alınan rubâîlerinde, genellikle ilahi aşk, toplumsal ahlâk, zamandan şikâyet, riya ve kibirden uzak durmanın gerekliliği gibi birçok konuya değinmiştir.İbrahim Aczî Kendî who lived the years between 1881 and 1965 in Konya is an important poet, a journalist, an investigate author, a mystic and a folklorist who raised by Konya in 20th century. İbrahim Aczî Kendi, worked as a tutor in Konya, improved himself by learning Arabian and Persian, prepared books about mysticism, literature and history. Devr-i zaman, which is written by İbrahim Aczî Kendî by himself and whose only transcript is registered with the number 104657/1 in Yusuf Ağa Library, is made of 360 Persian rubaies and their explanation which is written in Ottoman Turkish. In this study İbrahim Aczî Kendî's life and last 180 of 360 Persian rubaies are studied. Each of rubaies' Persian main texts are transferred to electronic environment. Parts that sometimes include translation, sometimes also include various types of explanations written Ottoman Turkish are transferred with Latin letters. İbrahim Aczî Kendî, rubaies that handled in this study, touches on many topics, such as sociel ethics, complaints about today's youht, hypocrisy and staying away from and arrogance
External interventions and the duration of civil wars
No full textThe authors combine an empirical model of external intervention, with a theoretical model of civil war duration. Their empirical model of intervention allows them to analyze civil war duration, using"expected"rather than"actual"external intervention as an explanatory variable in the duration model. Unlike previous studies, they find that external intervention is positively associated with the duration of civil war. They distinguish partial third-party interventions that extend the length of war, from multilateral"peace"operations, which have a mandate to restore peace without taking sides - and which typically take place at war's end, or at least when both sides have agreed to a cease-fire. In a future paper, the authors will examine whether partial third-party interventions - whatever their effect on a war's duration - increase the risk of war's recurrence. If that proves true, then even if interventions reduce the length of civil war, they may do so at the cost of further destabilizing the political system, and sowing the seeds of future rebellion.Children and Youth,Peace&Peacekeeping,Post Conflict Reconstruction,Post Conflict Reconstruction,International Affairs,Post Conflict Reconstruction,Social Conflict and Violence,Peace&Peacekeeping,Post Conflict Reconstruction,International Affairs
Effects of Initial Thinning on the Growth and Biomass Characteristics of Zizyphus spina-christi Trees
No full textSeedlings of Zizyphus spina-christi trees grown from seeds were planted intensively in the field at the Experiments and Research Station of College of Agriculture, King Saud University near Riyadh City. After
a year, the trees were subjected to thinning through three consecutive years and evaluated for growth and biomass production. Starting from the second year of thinning, the thinned trees increased stem diameter and
all above-ground biomass components. Branches and foliage biomass ratio also increased due to thinning at the expense of stem biomass ratio. Unthinned trees were superior in biomass production after three years of the treatment application.Corresponding Author:

Morphological and grammatical study of the fuctional derived nouns in the six anthologies by Sheikh Ibrahim Inyas / Ibrahim Shaaban
No full textThis research is a morphological, grammatical and analytical study on the multiplicity of the
scale of five derived nouns and their formulas as used in the six anthologies (dawawin) of
Senegalese Sheikh Ibrahim Inyas al-Kaulakhi, based on the chosen rulings, methods and context
used by the author of the six collections. The research focuses and discusses on the subject
noun, the accusative noun, the hyperbolic participles, the attributive participle,
comparative/superlative adjective, and their scales and formulas, both standard and nonstandard,
and the usage of their multiple meanings according to the methods employed in these
six dawawin, including infinitive and augmented noun of three or four lettered origin, with
grammatical rulings associated with alif and lam (al), as selected or chosen according to the
usage of Sheikh Ibrahim Inyas al-Kaulakhi. In order to find out the context of morphological and
grammatical methods, analyses were made that acquaint readers with the taste of Sheikh
Ibrahim's ability in applying morphological and grammatical rules. Through extrapolation, the
morphological and syntactic source of each derivative was separately traced in those six
dawawin. In reviewing the morphological and syntactic language of those derivatives, books and
the theories of ancient and modern linguists, according to consensus and contrast, were used in
shedding light on each derived noun by studying the ancient morphological and syntactic
sources according to the information and theories derived therefrom and made analysis
thereon. In this regard, a morphological or grammatical context was established using a
qualitative rather than quantitative approach based on which the research was conducted and
its structure, sections and chapters arranged accordingly, with clarification and detailed
analyses. Findings of this research have established the functioning of morphological structure
and scales of the five derived nouns as well as the semantic meaning, application and usage of
augmented derived nouns as dealt with in their grammatical rulings associated with the Arabic
definite article - alif and lam (al), to enable them function in the past, present and future tenses,
and what not. The research concluded with a revelation which is indicative of Sheikh Ibrahim
Inyas’ ability and mastery of morphological scales and grammatical expertise as though he lived
with and learnt from Khalil, Sibawayh, Ibn Jinni and Asma'i and their ilk
