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 4th, December 4th and January 4th). The results of the combined analysis of the two seasons showed that the delay of planting, date from November 4th to December 4th and January 4th 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.

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.

University of Aden Journal of Natural and Applied Sciences, Vol. 22 No. 2 (2018), 31 October 2018, Page 337-349



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%).

University of Aden Journal of Natural and Applied Sciences, Vol. 22 No. 2 (2018), 31 October 2018, Page 383-392



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.

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.

University of Aden Journal of Natural and Applied Sciences, Vol. 22 No. 2 (2018), 31 October 2018, Page 481-484



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.
