Two field Experiments were carried out at the Research Farm of Nasser’s Faculty of Agricultural Sciences, University of Aden (Delta Tuban) Lahej Governorate. during 2015/2016 and 2016/2017 seasons, to study the effect of intercropping patterns on yield and some yield components as well as competitive relantionships of maize and cowpea. This experiment included three interplanting systems(1:1, 2:1 and 1:2) for maize and cowpea respectively, in addition to sole cropping treatment. The results showed that the different interplanting systems significantly reduced biological yield, grain and seed yield/hectare of the two crops as well as a number of pods/plant of cowpea. Grain index (1000 kernel weight) of maize was significantly increased by interplanting systems ,except interplanting system(1:2) compared with pure planting in both seasons. The highest biological and grain yield of maize were obtained under(2:1) pattern, while biological and seed yield of cowpea significantly increased by (1:2) pattern, compared with the other intercropping systems in both seasons. Land equivalent ratio(LER) values indicated that intercropping cowpea with maize gave yield advantage at all intercropping patterns. Maize was the dominant intercrop, while cowpea was the dominated intercrop.

Al-zabor construction one of the old Yemeni building styles (Analysis study)

Ahmed Ibrahim Hanshoor

University of Aden Journal of Natural and Applied Sciences, Vol. 21 No. 2 (2017), 31 August 2017, Page 241-253



Al-zabor construction is one of the oldest multi– stories construction technique in Yemen, This technique is based on mixing clay with 30% sand, submerged in water for period time, then begins to build mud walls on a stone base,in the form of building layers by wooden molds. The building process is performed by filling the wooden molds with mud thrown by hand strongly; to achieve adhesion and connectivity with the foundation stone or mud bottom tier. After the layer dries relatively down,the construction begins to build another layer above it, and stacked layers successively until the of the structural construction complete is completed.

University of Aden Journal of Natural and Applied Sciences, Vol. 21 No. 2 (2017), 31 August 2017, Page 257-264



This study was carried out to investigate the effects of partial replacement of wheat flour (Buhooth 13) with naked barely the flour on chemical and rheological of composite flour, and qualitative and organoleptic characteristics of produced bread, using different replacement levels. Different types of composite flour were prepared via partial replacement of wheat flour (5, 15, 25 and 35%) with naked barley flour. Experimental obtained results showed positive relationships between content values (ash, protein, fat and crude fiber) and percentages of naked barley flour. Farinogram properties; such as dough water absorption, development time, stability and degree of softness (degree of resistance to kneading – critical kneading rate) were increased as an amount of replaced level increased. Whereas, Extensogram parameters showed that as naked barley levels increased in the blend, resulted in increased energy, elasticity (resistance to extension of dough), energy of dough and relative number (ratio of resistance to extensibility). Reduction in extensibility of dough was noted as levels of replacement and as fermentation time increased, but it was contributed to reduction in extensibility of dough. In respect of characteristic of bread specific volume, the obtained results showed a significant gradual reduction in values of specific volume as levels of replacement increased Organoleptic evaluation showed an overall reduction in the total sensory characteristics as levels of replacement elevated. Organoleptic evaluation revealed that composite flour with 5% naked barley flour was considered, to be the best treatment since excellent results were recorded, compared with the other treatments; therefore, can be recommended.

University of Aden Journal of Natural and Applied Sciences, Vol. 21 No. 2 (2017), 31 August 2017, Page 291-296



Tomato is known to contain nutritional components with several types of health-promoting actions. Lycopene which is an antioxidant present in tomatoes has been identified as being responsible for the beneficial effect of tomatoes. With the aim of increasing the antioxidants contents of tomato, two dark fruited single recessive mutants were crossed to produce double mutant with higher antioxidants contents. The high pigment (hp) mutant of tomato characterized by dark green fruits, when it is immature and deep red mature fruit which is a monogenic mutant of tomato, was crossed with atroviolacea (atv) monogenic non-allelic mutant which had the same phenotype. Although it was easy to distinguish the hpatv segregating double mutant in the f2 generation, the conformation of the hpatv double mutant was made genetically. The double mutant showed darker phenotype in stem, leaves,and much darker fruits due to higher pigments content. The double mutant qualitatively showed higher pigments content which is of great nutritional value the detailed estimation of the quantitative differences in pigments of the wild type, singlemutants and constructed mutant is recommended.

Adobe is a software development company established in 1982, and has developed a number of software applications for use in various fields.The program Animate cc (flash previously) is one of the most prominent products and is widely used in the design of programming and producing best animation websites. Adobe has included in Flash software releases (Adobe Flash Professional CS6,Adobe Flash Professional CS5.5, Adobe Flash Professional CS5 and previous releases) a text-processing library called Text Layout Framework(TLF). This library supports Arabic-language writing from right to left and supports left-to-right writing of numbers and texts written from left to right such as Latin numbers and letters. However, the versions of Animate cc have not include the text-formatting library, which resulted in the inability of designers and programmers to produce interactive Arab applications. In this research, we designed a component for writing in Arabic called Arabic Text component that contains a wide range of fonts, text control properties and the addition of aesthetic and artistic effects of Arabic characters that are not included in the previous versions of Flash. The ArabicText component is included once in the flash program components, then it is used for writing by inserting it into stage.

Qasem and Ali [15] defined the \(K^h– BR\)- affinely connected space. In thin space, they obtained the condition for some tensors to be birecurrent, proved some tensors are birecurrent, gave new definition for some tensors and found some identities. Also they defined for \(K^h–BR–\) Lands bergspace and obtained various identities in such space. In this paper we have used the property of \(K^h-BR-F_n\) in \(P2-like\) space and \(P^*\)-Finsler space. We have obtained different theorems for some tensors to be satisfying the conditions of the above spaces and various identities in such spaces were also obtained.

Lymphoid neoplasms are clonal lymphoproliferations and are heterogeneous in clinical presentation, histopathology, immunophenotype, and prognosis.
The objectives of the study are to determine the main subtypes of lymphoma at the National Oncology Center in Aden and to analyze the clinical parameters including age, gender, anatomic distribution (nodal and extra nodal), signs, symptoms, grading, and to compare our results with other geographic regions.
A total number of 127 cases of lymphoma were collected during two years, the diagnosis was based on histological morphology following the International Working Formulation Classification System. Data were subjected to statistical software; Statistical Package for Social Sciences SPSS version 19. Age, gender, type of lymphoma, anatomic location, signs and symptoms were computed in term of frequency.
This is a retrospective study of 127 cases of lymphoma during the years 2013-2014, the ratio of NHL to HL was 1.59: 1. NHL was 61.4% ,38.6% were males and 22.8% were females, with a male to female ratio of 1.68:1. Hodgkin lymphoma was 38.6%; 22.0% were males and 16.5% were females, with a male to female ratio was 1.3:1.
The most common age groups affected for NHL in both sexes was ≥ 60& 45-59, 22.8%& 15.0%, respectively, together accounting for more than 50% of NHL, while the most common age groups affected for HL was 30-44& 15-29, 14.2% &10.2% respectively, together accounting for more than 50% of HL. According to the grading of NHL, high grade lymphoma was 14.1%, intermediate grade 48.7%, low grade 37.2 %. Regarding the subtypes of HL, the most common subtypes were mixed cellularity and nodular sclerosis 57.1% & 38.8% respectively. NHL with nodal presentation was seen in 39.37% of cases, and extranodal 22.04%, while HL mainly was manifested as nodal in 37.79% and only 0.78% extra nodal. Swelling in neck, axilla, groin was the most common symptom for NHL and HL 48.7%& 67.3% respectively. Anemia was the most common sign for NHL and HL (62.8%&67.3% respectively), followed by hepatomegaly and splenomegaly in HL (38.8% & 51.0% respectively).
Non-Hodgkin lymphoma was twice the Hodgkin lymphoma. NHL was the most common in elder age group, while HL was in younger age group. Histological grade of NHL revealed the highest frequency of intermediate grade. Mixed cellularity was the most common subtype of HL. Nodal presentation predominate than extranodal. Lymphoma presents commonly as lymphadenopathy, fever, wt. loss, hepatomegaly, splenomegaly.

The aim of our work is to determine the frequency of metabolic syndrome with age and sex difference analysis. This is a cross-sectional study conducted at Al-Rayan Hospital, Mukalla, Hadhramout, Republic of Yemen, from 4/2013 to 10/2014. Metabolic syndrome was estimated according to the International Diabetes Federation (IDF) criteria. of 702 patients, 239 were diagnosed as metabolic syndrome (34%), females were more than males (52.7%, 47.3% respectively), and the mean age of males was significantly higher than that of females. Raised waist circumference was present in all cases, and was higher in males, followed by diabetics with no significant difference. This was followed by hypertension, systolic and diastolic blood pressures were significantly higher in males, followed by triglycerides which was non-significantly higher in males, the least frequent component was HDL which was significantly lower in males than females. A percentage of 50% and or more of males and female patients had four metabolic syndrome components. The percentage of metabolic syndrome was 34%. It was more common in females which affected by the syndrome earlier in age than males. Most patients had more than three component of the syndrome.

University of Aden Journal of Natural and Applied Sciences, Vol. 21 No. 2 (2017), 31 August 2017, Page 399-412



The structure and kinetics of the crystallization reaction of amorphous \(Cd_{10} Se_{90}\) were studied at different heating rates (5–30 K/min) under non-isothermal conditionsby X-ray powder diffraction, scanning electron microscopy (SEM) and differential thermal analysis (DTA) techniques. The Johnson–Mehl–Avrami(JMA) and isoconversional models were used to describe the DTA crystallization data.A strong heating rate dependence of the activation energy was observed when the data were analyzed using Matusita method. This variation of the activation energy was confirmed by the application of the isoconversional methods of Kissinger–Akahira–Sunose (KAS), Flynn–Wall–Ozawa (FWO), Tang, Starink, and Friedman. These methods showed that the activation energy of crystallization is not constant but varies with the degree of conversion and hence with temperature. This variation indicates that the transformation from amorphous to crystalline phase is a complex process involving different mechanisms of nucleation and growth.

University of Aden Journal of Natural and Applied Sciences, Vol. 21 No. 2 (2017), 31 August 2017, Page 413-420



Materials interact with pollutant in a very complex manner, the possibility of erosion, adsorption, desorption, transportation, deposition, and phase change will appear because of the interaction between the pollutant and the material surface. The effect of many other environmental effects also appear, like the effect of rain water in breaking away tiny rock particles (grit productivity). All the actions mentioned or any one of them may causes high damage or weaken the structure. This research highlights the importance of specific physical properties and material weakness, the effect of specific environmental factors (humidity, rain, and temperature) on materials, such as building materials and the potential occurrence places of cracks in the material, by knowing the quality of the material.

Groundwater wells are the major source of drinking water in Hadhramout-Yemen. The current study assessed the quality of fifty-five water wells data for coastal Hadhramout-Yemen. The samples were tested for physical parameters such as color, Hydrogen ion concentration (pH), electrical conductivity (EC), turbidity (Turb) and total dissolved solids (TDS). This assessment is based on comparing water quality of physical parameter values to the Yemeni standards, calculating the water quality index (WQI) for each well and the correlation coefficients (R) between each pair of the selected physical parameters. The correlation coefficient between (WQI), and the selected physical parameters was also calculated. The percentage of compliance to the Yemeni standards in water samples varies from 71.19 % for TDS to 100% for PH. The WQI reflects that most of the samples (forty-nine) are of good and excellent quality. A good relationship was found (simple linear regression) between the color and the turbidity. The current results show that all physical parameters of drinking water are more or less correlated with each other and the WQI, is a very useful and easy tool for monitoring drinking water.
