An exclusive study of weeds spread in Alqatten Directorate farms in Hadramout Governorate was carried out from 20/10/2015 to 20/11/2016. The aim of this study is to identify the types and number of weeds in the farms. The study area included 16 farms in 4 different regions. 42 plant species belonging to 22 plant family were identified. Grassy family was the most present with 7 species on this average of 16.67%. The most wide spread grass was، Cynodon dactylon and Setaria verticillata; as they were found in all studied farms, while Heliotropium longiflorum and Maerua crassifolia، were less prevalent، as they found separately (one in each farm). The study revealed that there is a difference in the number of weed plants in the farms studied. The high number of weed types was found at AL-Rashasha farm in Alaqqad area where 29 types of the total number of types were found in the place of the study on an average of 69%. The minimum number of weeds was found at Alkaraba area, in Al –Moustagbal farm where 11 types were on an average of 26.19% of the total number of types found in the place of study.

This investigation was carried out during 2016/2017 to study the effect of extract and powder of Licorice (Glycyrrhizaglabra L.) on the growth of onion (Allium cepa L. cv. Bafatiem). For this purpose a field experiment was conducted in a farmer field in the village of Al-Wahat, Tuban District,Lahej Governorate.The experiment consisted of 7 treatments: spraying licorice extract with three concentrations (5, 10, 15 g / L) and thev addition of powder to the soil at three levels (5, 10, 15 g / m²) in addition to the control (without spraying and without addition). The soil of the experiment was cultivated and the seedlings were planted in the permanent land. Spraying was done in three batches after planting in the field for 60 days with a two weeks gap (interval), and the plants were sprayed until the fully wetness. In addition, the licorice root powder was added to the soil during planting; the second was added after 60 days of the first batch and then the experiment was carried out using the randomized complete block design with three replicates. The results of the field experiment showed that all the treatments of spraying and addition of powder to soil gave the low values of plant, height, compared with control which gave the highest average plant height of 81.23 cm. Licorice extract spraying at 5g/L and the addition to soil of powder at 5 and 10 g/m² recorded the highest tuber blade number which reached to 20.47, 20.6 and 20.53 blade/plant. Thus, the addition of powder to soil at 5g/m² caused a significant increase in tuber blade number compared with control which was the lowest in tuber blade number and reached to 19.6 blade/plant. Onion plants treated with licorice powder at 15g/m² and spraying at 5g/L caused increase in the leaves area that reached 19.73 cm² and 18.82 cm² respectively. The difference was significant compared with control and all other treatments, except the difference was not significant between the spraying at 5g/L and addition to soil of powder at 5g/m². Licorice extract spraying at 5g/L and the addition of powder to soil at 5g/m² caused an increase in dry weight of total vegetative of 11% for both.

A field experiment was carried out at the Farm of Nasser's Faculty of Agricultural Sciences which located in Delta of Tuben, during 2011/2012 and 2012/2013 seasons, to evaluate three maize cultivars (Tehama-1, Taiz-2 and local one) in three planting dates (November 4^th, December 4^th and January 4^th). The results of the combined analysis of the two seasons showed that the delay of planting, date from November 4^th to December 4^th and January 4^th significantly reduced the number of days to 50% tassling and silking, plant height, ear height, leaf area of topmost ear, leaf area index, ear length, number of grains/ row, 100-grain weight, grain weight/ear, and grain yield/ hectare and this reduction ingrain yield was 10.96 and 21.31% in the second and the third planting dates compared with the first one, respectively. Cultivars had significant differences in all of the characters under study except ear diameter with the superiority of Taiz-2 and Tehama-1 over the local on by 28.14 and 25.46% in grain yield, respectively. The interaction between planting dates and cultivars significantly affected plant height and leaf area of topmost ear as well as grain yield and its components ear length, number of grain/ row and ear grain weight. Highly significant positive correlations were found between grain yield and previous yield components.

The experiment was carried out at the Department of Biology, Faculty of Education– Aden, University of Aden. It aims at knowing the effect of zinc element on the growth of tomato plants (Samia type). The study depends on the foliar spray by zinc, the leaves were treated by four zinc element concentrations (25, 50, 100 and 200 mg/L) and another without treatment used as control. All treatments and control were repeated for three times. The tomato seeds have been planted in black plastic bags and then sprayed twice with zinc. The first foliar spraying was after appearance of the real leaves (4-6) and the second spraying was done after on month. The results revealed that all the zinc treated leaves of the tomatoes plants showed higher values for the vegetative qualities. The concentration (200mg/L) of zinc treatment showed a best result of vegetative qualities like length and diameter of the stem, root length, leaves area and dry and wet weight of the root and stem and chlorophyll content of leaves, compared to the other treatments.

This study was conducted in the Research Farm of the Faculty of Agricultural and veterinary medicine- Ibb University, Yemen, in 2012 – 2013 to study the effect of 4 levels of phosphate fertilizer, (tri super phosphate 46%(T1(0) T2(100), T3(200) and T4(300) )kg/ha P2O5) on alfalfa forage. The experimental design was randomized complete Block deign (R.C.B.D) in quadruplicates. The results showed a significant difference among the treatments (T3, T4, T2), respectively, and control (T1) in each of harvests (2, 5, 7, 8, 9, 10 and11), also showed significant difference between T3 and T4 compared with T2 in the harvests (2,4) with the highest plant high in (T3) in most harvests. The number of branches was not significant except between both of T3, T4 and both of T2, T1in harvest 9. The production of alfalfa forage were between (3.78- 18.67 t/ha) the production was increased with the increasing of P levels up to (200kg/ha) T3, and it decreased at (300kg/ha) T4.There were significant differences with the three treatments and control at (p≤ 0.05) where the highest differences were for T3 followed by T4 in all harvests, and there were differences among T3, T4 and T2 which surpassed T1. Dry matter and fiber were increased by P increasing directly.

This study focuses on the estimation of heavy metal concentrations in the protected environment of Al-Hoswah, Yemen, Aden. The heavy metals were of great importance in this study, such as cadmium (Cd), cobalt (Co), copper (Cu), iron (Fe), manganese (Mg), lead (Pb)and zinc(Zn). For this study, the samples of water reaching to Al-Hoswah protected environment and some other samples of soil, plants, such as grass, Sorghum bicolor (L.) moench , Azadirachta indica (L.) A.juss, Pithecellobium dulce (Roxb.) Benth, weed and grass were analyzed by the Atomic Spectrometer (AS), for the estimation of the heavy metals concentration in samples. The findings of the study revealed that the concentration of zinc, cobalt and lead in the treated wastewater which reached to Al-Hoswah protected environment are less than the allowed limit for irrigating the plants. Besides, the concentration of cadmium was in its maximum allowed limits, while the concentration of manganese slightly exceeded the allowed limit. Iron also exceeded the allowed concentration for irrigating the plants. It has been appeared that the soil content of the simple easy iron and zinc elements in depth of 25-50cm were greater than the critical limit of the element in the soil of agriculture, while the concentration of manganese element in depth was found at its lowest critical limit. But, the concentration of zinc, lead, cadmium and manganese in the studied plants was at the allowed limit. Furthermore, the concentration of cobalt in the samples of weed, grass, Neem tree and the Deiman tree was a little raising of the natural level. The concentration of iron was high in all the samples and less concentration was found in sorghum.

The aim of this paper is to study the quality of drinking water of the Al-Ain and its surrounding, comparing it with the local and international standards.

The study have shown that the drinking water of Al-Ain project is unsuitable for human requirement or use. The bacteriologic ally results show that most of the samples under study are bacteriological polluted with (Most probable number) (MPN) with degrees ranging from (100 and above).

This study was carried out during different seasons between 'August 2015 to February 2016 in the Dhala District Dhala Governorate, during the study identified on 59 plant species belonging to 49 genera of 31families that are used in different medical purposes. Varied plant parts of use as noted above the use of the plant leaves have more uses than any other parts (44.06%), followed by the succulents part (25.42%), then the fruits by 8.47%), followed by the roots, stems (6.77%) each. ,seeds ,full plant (3.38%) each, and the lowest percentage represents (1,69%). The sicknesses that are treated by the plant parts verified the inner sicknesses such as stomach, worms, diabetic, kidney, in addition to the outer sickness such as the treatment of wounds, vitilago and Burns … etc, and the method of usage could be specified by the type of disease and the used plant.

This study presented an applied model for the use of geographic information system GIS in the construction of geographical database of the morphometric characteristics of their drainage systems in the Haidibu-Socotra Island area to obtain an understanding of hydrological characteristics. The study has been concluded with a number of findings. As a result, the morphological analysis was carried out for the three main basins of Hidibuplain, namely Wadi Fardahaa basin, covering 28 km², Wadi Danajn basin, covering 15.3 km², Wadi Sawaq Basin, covering 43 km². The study of the morphological characteristics of drainage basins in the Hidibu area found that they all are in the growing stage. The large number of gorges, undulation of watershed divides, rectangular shape, are good evidences about growing stage of drainage basins in the study area. Due to that, the arrival of the flood is delayed after the storm. The study revealed that, low value of Texture Topography and coarse shape ofdrainage basins, due to the dominance of the structure rifting, showed the large number of faults and joints that contributed to increased leakage and reduced runoff. The study recommended that the flow at downstream of the catchment areas must be regulated, especially in the lower part of Fardahaa basin that crosses the highly populated city in the island (Haidibou city). The study also recommended the necessity of establishing water measuring stations in the wadis for the purpose of regulating water flow and utilization in agriculture and other human uses.

In this study, the mechanical properties (toughness Tensile) of the 6063 aluminum alloy were improved by reinforcing it with a continuous three-dimensional metal fiber mesh by weaving metal wires of wrought steel Diameter (0.4mm) and by weaving each layer of wire independently, each layer was weaved with the next layer (the first layer with the second layer, then the second layer with the third layer... etc), in order to obtain a mesh of continuous woven fibers. The mesh was placed in a metal mold, poured the 6063 aluminum smelter at 800 °C and kept the mold inside the furnace for 30min. The process of filling the melt was completed within the mesh, then the mold was cooled and the reinforced alloy was obtained. Standard samples were tested for their tensile properties and the results were compared with reinforced Alloys by particles of aluminum oxide, or titanium oxide or silicon carbide. It was observed that the aluminum Alloy toughness Tensile & yeild point were increased after using the reinforcing Particles, while there was a noticeable increase in them when the aluminum was reinforced with a mesh of three dimensional reinforcing fibers, while there was a decrease in the elongation.

The Study of the Effect of Aluminum powder on the bending resistance properties and fire retardant for unsaturated polyester, which is manufactured in Turkey, a function of the percentages of Aluminum powder (0.5%, 0.8%, 1%, 1.5%, 2%, 2.5%), a particular size (150 µm), were investigated through several variables, such as, bending resistance and the flame resistance. In addition, the samples of the base material (unsaturated polyester) were measured in a pure and when the aluminum powder was added by optical microscopy. Absorption spectrometer measurements were taken in the infrared (FTIR) area of the pure and the polymer with the weight ratios of the fillers. The results lead to that the strength at bending resistance is (140 Mpa) at the percentage (0.8%). The obtained results appeared that, when the added Aluminum powder to reduce the spaces between the polymer chains, which reflects the high ability of the polymer against the applied stress, the degree of homogeneity is high between polymer and additives. Also, the results indicated a lowered percentage in bending resistance at the percentage (2.5%) is (84.3Mpa), and observe that the average time of burning starts strong impact when (0.5%) as increasing to (168 Sec) and then begins to decline behavior when increasing proportions weight and then increasing behavior when increasing proportions when (2.5%) as increasing to(195 Sec). The results also indicated that the percentage for the time of burning ranged between negative values at the low weight ratios of the added (1.5% - 0.5%) and positive values at the high weight ratios (2% -2.5%).

A laboratory experiment was conducted to study the effects of salinity and presoaking treatments on final germination percentage, days to 50% germination, and recovery percentage of Nigella sativa seeds. Seeds were divided into two groups and for 24h one group was presoaked in different NaCl concentrations (25, 50, 75, and 100 mM), while the other was presoaked in distilled water. They were then sown in Petri dishes and watered with salinity treatments. Results showed high significant difference between the two presoaking treatments. Final germination percentage of seeds of the first group was negatively affected where it decreased as salinity concentration increased. Only seeds at 25 mM reached to 50% of germination after ten days, while those at other concentrations failed. Results also showed that seeds of the second group were germinated well after being exposed to salinity stress. They also achieved more than 50% germination during the first five days of experiment. The recovery percentage of the un-germinated seeds of the two groups was low indicating toxic ionic effect on seed germination and viability. It was concluded that salinity effect on germination traits increases with the increase in concentration and presoaking treatment in distilled water helps seeds to reduce salinity stress.

This study was designed to compare the production performance of both Ross 308 and Marshall R Plus broiler breeder strain, whereas the ambient temperature ranged between 7.9ºC to 30.10ºC. A total of 36,000 25 wks- old hens of broiler breeders Marshall R Plus and Ross 308. The hen of each strain (18000 hens) was randomly distributed to five open houses as replicates (3,600 hens per house). Fed ad libitum on balanced ration and available water according to Management Guide recommendations for each strain. Production performance percentage, such as egg production of hen housed (HH) and hen day (HD), feed intake (FI), feed conversion ratios (FCR), mortality, selected and unselected eggs for hatching, broken and a double yolk, was recorded from 26 to 57 weeks of age. The whole production period divided into eight production periods for each strain by randomized complete block design as 2 × 8 factorial arrangement of treatments. The results showed significant differences in strain, production period and their interaction on HD, HH, FI and FCR. Ross 308 strain had higher HD and HH, lower FI and better FCR than Marshall Strain. Also, the strain and production period had a significant effect on the selected, unselected, broken and double yolk and mortality. Ross 308 strain had higher selected eggs for hatching, broken and mortality and lower unselected and double yolk eggs than Marshal strain during the completely experimental period. It can be concluded from this study that Ross had better performance in all studied traits except mortality and broken eggs percentages.

Honeybee hives were setup in Feeg village of Al-Baha province- Saudi Arabia, where Ficus palmata plants are dominant in the Juniperus procera forest. Propolis samples were collected from these hives for over a year. The propolis samples were extracted using three different solvents including dichloromethane (DCM), mixture of dichloromethane and methanol (DCM:MeOH, v:v, 2:1) and methanol (MeOH). The chemical compositions of the different propolis extracts were determine by gas chromatography-mass spectrometry (GC-MS). The total phenol content (TPC) in each extract was quantified using the Folin-Ciocalteu method. The free radical-scavenge activities (FRSA) of the various propolis extracts were measured by the method of 1,1-Diphenyl-2-picrylhydrazyl (DPPH). The chemical analysis showed that the propolis extracts of the different solvents varied in composition and contained mainly diterepenoids, triterpenoids, fatty acids, n-alkane, and n-alkene. The TPC ranged from 30.5±7.8 for DCM to 168.5±23.3 mg GA/g for DCM:MeOH propolis extracts. The FRSA ranged from 6.56 % for the DCM to 19.22 % for the DCM:MeOH extracts of July 2014. The MeOH extracts of the propolis showed higher toxicity against Escherichia coli and Staphylococcus aureus than the DCM:MeOH propolis extracts. The latter extracts showed the highest toxicities against Candida albicans and Aspergillus niger.

Chub mackerel Scomber japonicus (Scombridae) is a pelagic species that inhibits warm and temperate coastal waters of the Atlantic, Indian and Pacific Oceans. The topological characteristics of the mouth cavity of the carnivorous fish S. japonicas was studied by using light microscope. The results revealed that all the teeth of S. japonicas are pointed and canine-like, papilliform teeth present on the premaxillae and the anterior regions of the dentaries are associated with seizing, grasping and holding of prey. The morphology and distribution of different taste buds of S. Japonicas were predominantly localized at tongue and the anterior regions of the mouth cavity. Two types of taste buds are elevated from the epithelium at different levels, which may be useful for ensuring full utilization of the gustatory ability of the fish, detection and analyzing of taste substances, as well as for assessing the quality and palatability of food, during its retention in the mouth cavity. Observations of the surface architecture of the mouth cavity of S. japonicas have been discussed within the context of feeding and habitat preferences, as well as ecomorphological adaptation of the species.

In the present paper, a Finsler space F_n whose Cartan's second curvature tensor P\(_{jkh}^i\) satisfies \(P_{jkh|l|m}^i=a_{lm} P_{jkh}^i, P_{jkh}^i\) ≠0, where \(a_{lm}\) is non-zerocovariant tensor field of second order , is introduced and such space is called as P^h–birecurrentspace and denoted briefly by P^h–BR–F_n. The aim of this paper is to obtain some birecurrent tensors in this space. Also, we introduced Ricci birecurrent space. We proved the projection of some curvature tensors on indicatrix are birecurrent.

There is an evidence that inadequate clinical information is associated with an increased level of inaccurate reports. In our practice, we have noticed that sonography requests sometimes do not contain enough information to aid to better sonography report. The aim of this study is to analyze the requests for sonography examination in the Emergency Department of Algamhuria Modern General Hospital –Aden- Republic of Yemen, and to determine if requests provide adequate information for sonographers. We have retrospectively reviewed 250 randomly selected request forms received by the ultrasound unit of Radiology Department, at the Emergency Department. The ultrasound most frequently requested by area is the abdominal and pelvic ultrasound, being 80.8% of the analyzed requests while one (0.4%) did not have the specific part of the body area to be investigated written on the request form. Four requests (1.6%) with no patient's name (s) and seven (2.8%) with no father name (s). Eighty eight requests (35.2%) did not have date of request on it. One hundred and twenty seven (50.8%) of the request form did not have the age of the patient. Patient status wasn't mentioned in almost all except 9 /250 (3.6%). Clinical and laboratory information were absent in 128(51.2%) of the requests forms. Only 10 (4%) had information of previous radiographic investigations, while 240 (96%) did not have any previous radiographic information.. Two hundred and nine (83.6%) of the request forms had the doctors names and signatures on the request. Our audit’s data analysis revealed that only two of the 250 requests reviewed were completed in full. We found that requests for sonography examination in the Emergency Department of our hospital haven't provided adequate information for sonographers.

Non-Hodgkin’s lymphoma (NHL) is a common hematological malignancy, it's incidence has been rising globally since the 1970s with an increasing prevalence of diabetes mellitus (D.M) and NHL, the number of patients suffering from both diseases is growing. Among adult patients, regardless the gender, the second most common cancers among Yemeni population was NHL with 8.0%. This is a descriptive record-based study of 42 NHL cases admitted to Al-Sadqa Teaching Hospital, ‎National Oncology Center - Aden, from 1st January to 31st December 2017, to identify the prevalence of D.M among NHL patients. In this study, there was 6.37% of patients admitted with NHL,11.9% of them with history of DM, the mean age was higher for patient with diabetes 62.6 ﻍ7.7, male patient percentage was higher with 13.6% and obesity with 42.9 % among patients for NHL and D.M. In this study, 76.8 % of patients treated by CHOP (cyclophosphamide, doxorubiicin, vincristine and prednisone) regime with only adjustment of prednisolone dose for diabetes patients. This study provided, for the first time, the prevalence of diabetes among NHL patients.

In this work, common analytical expression for potential energies of molecules (interaction energy between electrons and nuclear, and between electrons), and kinetic energies of electrons have been obtained. As basis functions Slater , Atomic Orbitals have been used.

Congenital methemoglobinemia is a rare overlooked differential diagnosis in patients presented with generalized (peripheral and central) cyanosis unrelated to cardiopulmonary causes. Here, we report a case of 9-year-old boy who was diagnosed as methemoglobinemia. He was presented with peripheral and central cyanosis, while his cardiovascular and respiratory system were normal. This case stresses the importance of alertness among the treating physicians to this disease occurring in a patient with cyanosis unconnected to cardiopulmonary causes.
