Egg Yield and Quality in Laying Hens Fed Diets Containing Black Cumin Seed and/or White Wormwood Leaves
Bakheit A. Yagoub,Ahmed E. Amin,Nabiela M. El Bagir,Ahmed Alhaidary,Hasab E. Mohamed,Anton C. Beynen
Journal of Animal and Veterinary Advances , 2012, DOI: 10.3923/javaa.2010.2600.2603
Abstract: Laying hens were fed diets containing either black cumin seed or white wormwood leaves or the combination of the two additives and the effects on egg production and egg quality characteristics were determined. Final body weights were significantly increased in the birds fed the diet with 1% black cumin seed and in those fed the diet with 0.5% of both black cumin seed and white wormwood leaves. Feed intake was numerically lower after the feeding of the diets with 1% white wormwood leaves. Egg production was not significantly influenced by dietary treatment but group-mean egg production was lowered in the hens fed the diet with 1% black cumin seed. Feed conversion efficiency was significantly decreased by the diet containing 1% white wormwood leaves and by the diet with the combination of 1% of black cumin seed and 1% white wormwood leaves. The diet containing 0.5% black cumin seed plus 0.5% white wormwood leaves also significantly decreased feed conversion. Egg weight, shape index, albumen height, Haugh unit, shell thickness and yolk color were not significantly affected by the dietary treatments. The major finding of this study may be that dietary white wormwood improved feed efficiency in laying hens whereas black cumin seed did not.
Bilateral origin of ovarian arteries from accessory renal arteries
Mohamed A. Bakheit
Saudi Medical Journal , 2012,
Abstract: Ovarian arteries generally arise from the anterolateral (or lateral) aspect of the abdominal aorta caudal to the origin of the renal arteries at the level of L2 vertebra. The ovarian arteries may arise from the renal, suprarenal, inferior phrenic, superior mesenteric, lumbar, common iliac, or internal iliac arteries. This was a unique case, in which both ovarian arteries originated from 2 differently-originating bilateral accessory renal arteries. This unique variation may provide significant information to surgeons and gynecologists dissecting the abdominal cavity. The case was found in a female cadaver aged 55 years during routine dissection in the Anatomy Department, College of Medicine, University of Dammam, Kingdom of Saudi Arabia in 2009. The subject had an average built without any abnormal external features. Both right and left ovarian arteries arose from the bilateral accessory renal arteries. Knowledge of ovarian arteries and their definitive course to the ovaries is of great interest to the anatomists, surgeons, radiologists, urologists, and gynecologists to avoid clinical complications during surgical interference, or radiological examination of this region.

Amani A. Beshir,Yagoub M. Yagoub,Salih Ahmed Babiker
Pakistan Journal of Nutrition , 2009,
Abstract: The present study was conducted to evaluate water melon (Citrullus Lanatus) seed cake as a possible protein supplement for growing Iamb in comparison to groundnut cake. Graded proportion of water melon seed cake (WMSC) (0, 25, 50, 75, 100%) which replace groundnut cake (GNC) were incorporated in five diets iso-caloric, iso-nitrogenous diets for lamb. Diet A contained 0% proportion of MWSC, diet B, C, D and E contained 25, 50, 75 and 100% WMSC proportions, respectively. Forty five yearling male lambs of Sudan desert sheep ecotype Kabashi with average body weight of 31.5kg were used for feeding trial. There was a significant (P < 0.01) linear decrease in feed intake and average daily live weight gain with increasing WMSC level in the diet, but dietary treatments had no significant effect on feed conversion efficiency and final body weight. However, lambs fed diet A (0% WMSC) was found to be superior over the other treatment groups in previous parameters.

Farah A. Mohammadi;Mustapha C. E. Yagoub
PIER B , 2008, DOI: 10.2528/PIERB07101802
Abstract: This paper presents an accurate and robust time-domain electromagnetic model for microwave components of integrated circuits. The time-domain model has been validated on different structures such as metallic waveguides, planer lines and the transition of waveguide-microstrip line under harmonic oscillation excitation. The results obtained from simulation were compared to the experimental test results. The simulation results demonstrated that the approach is suitable to model microwave components of integrated circuits.

Journal of Geoscience and Environment Protection (GEP) , 2018, DOI: 10.4236/gep.2018.65004
Abstract:
The aim of this study is to investigate the impact of temperature trend on glacier-mass balance, snow density, snowmelt, snow depth and runoff by using observations of nine glacier stations that covered most of the China over the period of 1979-2013. Trend analysis showed an increasing trend of temperature on all of the selected stations. On an average, temperature was increasing at the rate of 0.46/10a. The increasing trend of temperature showed a negative relationship with annual glacier-mass balance on most of the stations and caused a decrease in annual balance. Results of Pearson’s correlation analysis showed a highly significant negative correlation between temperature and snow density (correlation coefficient (CC = -0.661 at 0.01 significance level). There was a significant positive correlation between temperature and snowmelt (CC = 0.532 at 0.01 significance level). There was a significant negative correlation between temperature and snow depth (correlation coefficient (CC = -0.342 at 0.05 significance level). Moreover, there was a significant positive correlation between temperature and runoff (CC = 0.586 at 0.01 significance level). Increasing trend of temperature caused an increasing trend of annual snowmelt and runoff anomaly% at the rate of 24.82/10a and 9.87/10a, respectively. On the other hand, a declining trend in annual snow density and snow depth anomaly% was found at a rate of -5.32/10a and -1.93/10a, respectively. We concluded that the snow density, snowmelt and runoff are significantly sensitive to temperature in China. This contribution has provided information for further understanding of glacier variation and its influencing factors.

Research Journal of Applied Sciences , 2012, DOI: 10.3923/rjasci.2010.285.302
Abstract: The study integrates the results of field observations, petrographic investigations and whole-rock/wall-rock alteration chemistry to emphasize the occurrence of gold mineralization at Al Abeidiya area, Northern Sudan and to determine its type and distribution, as well as the geological, mineralogical and geochemical controlling factors. The area is a regionally metamorphosed terrane underlain by crystalline Proterozoic basement complex comprising predominantly low to medium-grade, altered and polydeformed, calc-alkaline metavolcanic rocks and minor metasediments intruded by medium to high K, calc-alkaline, metaluminous and I-type granitoidal batholiths that emplaced as volcanic arc plutonics above a Noeproterozoic subduction zone during the syn to late collision stages of crust evolution of the Nubian Shield. The study confirmed the existence of promising medium to high-grade gold mineralization (with content ranging between 0.01-24.0 g ton-1) occurring as a shear zone-hosted, gold-quartz, gold-sulfide and disseminated gold formations in gold-bearing quartz veins, veinlets, sub parallel stringers and wall rock alteration zones. It is hosted by intensely sheared and hydrothermally altered granitoids and the surrounding greenschist-facies assemblages as well as, the ophiolitic sequences and controlled by post-batholithic brittle-ductile deformation with different intensity of shearing and hydrothermal alteration. Gold is preferentially encountered as fine to medium-grained native gold or as dispersed, tiny invisible grains associated with sulphides. Pyrite, arsenopyrite, sphalerite, chalcopyrite and minor galena, malachite, pyrrhotite and chalcocite are the sulfide phases associated with the gold, whereas iron oxide (limonite), carbonates (ankerite, siderite and calcite), chlorite and minor talc occur as gangue minerals. The country rocks locally suffered an extensive wall rock alteration that developed around the mineralized zones and encountered as; sericitisation, carbonatisation, chloritisation, pyritazation, silicification kaolinitisation and epidotization. Au-mineralization postdated metamorphism, older shearing/faulting events and batholithic intrusion and was synchronous with the latest stage of shear-induced deformation. The mineralization is interpreted as consistent with mesothermal type of hydrothermal deposits, where post-metamorphic and syn-deformation hydrothermal fluids ascending through channel ways within sheared zone leached elements from the metavolcanics and the nearby mafic/ultramafic rocks and precipitated in the host rocks. The credible energy sources for the hydrothermal activity that brought about the mineralization is likely unexposed intrusions at deeper levels within the shear zones.
Geochemistry and Geotectonic Setting of Neoproterozoic Granitoids from Artoli Area, Berber Province, Northern Sudan
N.H. Lissan,A.K. Bakheit
Journal of Applied Sciences , 2011,
Abstract: The research aimed at deciphering the genetic relationship of the Artoli area, Berber Province, Northern Sudan with the domains of Saharan Metacraton and Arabian Nubian Shield and tries to define the boundary between them. In order to determine the tectonic environment, the petrographic characteristics and the original protoliths of granitoid rocks occurring within the area, several discrimination and variation diagrams were constructed using their whole-rock geochemical analysis and integrated with field observations and petrographic investigations. The results revealed that the rocks constitute voluminous, intermediate to acidic granitoidal batholith of granodiorite, quartz-diorite and diorite with lesser amount of granite that emplaced in a crystalline Proterozoic basement complex, comprising of low-grade schistosed metavolcanic rocks and minor high-grade metasediments. The Artoli granitoids are identified as medium-to high-K, calc-alkaline, metaluminous and I-type granitoid suite emplaced as volcanic arc granites above a Noeproterozoic subduction zone during the syn- to late-collision stages of crust evolution. The magmas of these granitoids were derived from the mantle with involvement of minor crust components. The overall geological and geochemical characteristics of the Artoli granitoids are comparable to the plutonic rocks of the Arabian-Nubian shield in Arabia, Egypt and NE Sudan. Thus, the area considered as a part of the westernmost Nubian Shield with its boundary with Saharan Metacraton lying further west.

Pakistan Journal of Nutrition , 2008,
Abstract: Indigenous furundu is prepared by cooking the karkade (Hibiscus sabdariffa L.) seed and then fermenting it for 9 days. Physicochemical properties and HCl-extractability of minerals of the karkade seeds and of furundu ferments were analyzed. Microbial growth during fermentation was also screened. Furundu fermentation resulted in increase in total protein of the karkade seed, suggesting changes in dry matter composition. Significant decrease in karkade seed protein fractions, albumin plus globulin and prolamin and a significant increase in G1, G2 and G3 on fermentation was found. Also a decrease in total acidity and pH was observed. The amino acids profile of the karkade seed was dominated by glutamic acid, aspartic acid and arginine. The sulfur amino acids (Methionine and cystine) and threonine were the limiting amino acids in karkade seed and they remained limiting in furundu. Slight mobilization in amounts of some amino acids, simultaneously with increase in the level of ammonia during preparation of furundu was noticed. The contents of K, Na, Cu, Mn and Fe of the karkade seed were decreased significantly in furundu. The HCl-extractability of K, Mn and Fe in karkade seed was improved in furundu product. Fermentation of the cooked seed increased growth of bacteria, yeasts and moulds. The endospore-forming Bacillus species is predominately the active organism in the substrate medium.

Abstract: A field experiment was conducted for two consecutive seasons (2009/2010 and 2010/2011) on the Demonstration Farm of the College of Agricultural Studies, Sudan University of Science and Technology at Shambat, to study the effect of some fertilizers on growth and yield of soybean (Glycine max L. merril). The experiment was laid out in a randomized complete block design (RCBD) with four replicates. The fertilizers treatments consisted of three types of fertilizers: urea (180?kg/ha), NPK (361?kg/ha), compost (%) and the control. The results showed that fertilizers treatments in first season had significant difference on number of pods/plant, economic yield, harvest index. Mean while, highly significant difference on green, biological and straw yield. In second season fertilizers treatments had significant difference on plant height at 30 days, leaf area at 45 and 60 days, green yield, biological yield and straw yield. 1. Introduction Soybean (Glycine max L.) is a member of Leguminosae family, rich in nutrients, and it is regarded as a nutrient storage. Soybean is not only seen as an oil plant but also used for various purposes [1]. Among grain legumes, soybean is an economically important crop that is grown in diverse environments throughout the world. Its adaptation to tropical and subtropical regions is still involving extensive breeding work [2]. To use land continuously for crop cultivation, incorporating organic and inorganic fertilizers to soil would provide multiple benefits for improving the chemical and physical status of the soil which results in improved crop yield [3]. Organic fertilizers include compost, farm yard manure (FYM), slurry, worm castings, urine, peat, green manure, dried blood, bone meal, fish meal, and feather meal [4]. Inorganic fertilizers include sodium nitrate, rock phosphate, limestone, ammonium nitrate, potassium nitrate, NPK fertilizers, muriate of potash (MOP), and supper phosphates [5]. Both organic and inorganic fertilizers are sources of mineral elements, which plants require for effective growth and development. Essential mineral elements are required in optimum amounts and are classified into micro and macro. Nitrogen, phosphorus, and potassium have great effects in plant growth and development. Their deficiencies or excesses result in marked effects on the growth and yield of crops. Nitrogen is a chlorophyll component, and it promotes vegetative growth and green colouration of foliage [6]. Phosphorus plays a major role in photosynthesis, respiration, energy storage, cell division, and maturation. Potassium is
