Potato crops occupy high rank among different agricultural crops as per its production and consumption despite its propagation high cost by tubers due to the rising of its import quotation. Thus a lot of attempts were done to propagate it vegetatively in order remain its genotype constant. For this purpose, two experiments were independently carried out, the first one was in Sana’a-Yemen by using perlite medium and the other one was in Mitem, Ibb governorate by using sand medium, both were under plastic tunnel conditions, in April during summer agriculture season. The aim of this research was to study the effect of different concentrations (0, 150, 300, 450 and 600 ppm) of indole butyric acid (IBA) and three types of cuttings (terminal, medium and basal) on rooting and growth of potato cuttings. The result showed that IBA at 450ppm recorded the best values for all studied parameters in perlite medium. Terminal cutting gave the highest values for all investigated parameters irrespective of cutting type. Interaction between IBA at 450ppm and terminal cuttings was the best significantly at all studied parameters. Almost all results by the use of sand medium with the three types of cuttings and IBA with its determined concentrations were similar to those produced by perlite medium in general. This investigation demonstrated the probability of propagation of potato crops vegetatively by using stem cutting.

This study was conducted on sexually mature male rats weighing 200-230gms. Topographic characteristics of an individual animal under experiment were studied in an open field manner (10). The rats were divided into three groups: stimulated, balanced and inhibited by the nervous system. Emotional stress leads to the activation of the peroxide oxidation of fat as a result, biological antioxidants as a result of the enzymes of this system. Results showed substantial transformations due to emotional stress in the microvascular circulation system (slow electrical movement red blood cells, blood flow velocity, vascular cavity change, high blood vessel deposition velocity, redness and transport function of red blood cells [Co2, O2]). Resistance of red blood cells peroxide was insignificantly lower in balanced animals compared to stimulated animals, while in inhibited animals there was an increase, compared to balanced animals.

The objective of the present study is to investigate risk assessment and geochemical forms of Pb, Mn, Zn and Cu in Aden Coasts sediments as well as the content of sediment texture, organic carbon, and carbonates. Sequential extraction technique was applied to estimate the metals in five different fractions; exchangeable, bound to carbonate, bound to oxides, bound to organic matter and residual. The results indicated that the metals bound to non-residual fraction (anthropogenic input) represent 72.8 % of the total extractable fractions for Pb, 79.7 % for Mn, 87.4 % for Zn, and 87.3 % for Cu. The five fractions of the metals in the present study could be arranged in the following sequence: Residual > Exchangeable > Oxide form > Organic form > Carbonate for Pb; Residual > Oxides form > Organic form > Carbonate > Exchangeable for Mn or Zn; Organic form > Residual > Oxide form > Carbonate > Exchangeable for Cu. The risk assessment of the metals showed medium risk for Pb at all sampling sites except Sira zone which revealed very high risk to aquatic environment. Fractionation pattern of Zn and Cu showed low risk, while Mn showed low (most sites) to medium risk (Sira and Caltex) to aquatic environment. In general, the risk assessment of the metals in the study area decreased as follows: Pb >Mn>Zn> Cu.

Reservoir description is a process of describing various reservoir characteristics using all the available data. The nature of the description of reservoir properties is related to the availability of sample data and geologic complexity of reservoir. Reservoir characterization is needed for effective reservoir management studies. Reservoir rock properties can be estimated by several methods. Rock properties are determined by performing laboratory analyses on cores extracted from the reservoir. However, obtaining the properties from core analysis or well logging is time consuming and an expensive operation. For that, in this work, new models for estimating rock properties (porosity, permeability) are developed by adapting Artificial Neural network model (ANN). Models were successfully demonstrated for predicting reservoir rock properties (porosity and permeability) forBiyad formation of Kharir oil field. The models were tested against properties yielded from core laboratories using statistical error analysis. Result showed a great potential in predicting reservoir properties using artificial intelligence models.

A Finsler space \(F_{n}\) for which the h(v) - curvature tensor \(U_{jkh}^{i}\) satisfies the condition \(B_{m} U_{jkh}^{i}\)=\(λ_{m} U_{jkh}^{i}+μ_{m} (δ_{j}^{i} g_{kh}+δ_{k}^{i} g_{jh} )\), where \(λ_{m}\) and \(μ_{m}\) are non-zero covariant vector fields and \(B_{m}\) is covariant derivative of first order in the sense of Berwald (Berwald’s covariant differential operator). In the present paper, satisfying this condition will be called a generalized \(B_{m} U\)-recurrent space. The tensor \(G_{rkh}^{r}\), the h(v)-torsion tensor \(U_{kh}^{i}\), the G- Ricci tensor \(G_{jk}\) and the U- Ricci tensor \(U_{jk}\) are non-vanishing. Under certain conditions, a generalized \(B_{m} U\) - recurrent space becomes a generalized recurrent tensor. Also, we discuss the decomposing of the h(v) - curvature tensor \(U_{jkh}^{i}\) in Finsler space.

In this paper, we have applied the mapping method to solve the (3+1)-dimensional Boussinenesq equation where we have obtained exact solutions for evolution equation to construct exact periodic and soliton solutions of nonlinear partial differential evolution equation. Many have obtained new families of exact traveling wave solutions, but the Boussinesq equation is successfully. These solutions may be significantly important for the explanation of some practical physical problems. New exact travelling wave solutions are obtained and expressed in terms of hyperbolic functions, trigonometric functions, rational functions and elliptic functions. It is shown that the mapping method provides a powerful mathematical tool for solving a great many nonlinear partial differential equations in mathematical physics.

The aim of this paper is to prove new variations of uncertainty principles for Weinstein operator. The first of these results is variation of Heisenberg-type in equality for Weinstein transform that is for s>0. Then, there exists a constant C(α,s), such that for all f∈L\(_{α}^{1}\) (R\(_{+}^{d}\) )∩L\(_{α}^{2}\) (R\(_{+}^{d}\))
\(‖|x|^{2s} f‖_{L_{α}^{1} (R_{+}^{d})} ‖|ξ|^{s} F_{W} (f)‖_{L_{α}^{2} (R_{+}^d)}^{2}≥C(α,s)‖f‖_{L_{α}^{1} (R_{+}^{d})} ‖f‖_{L_{α}^{2} (R_{+}^{d})}^{2}.\)
The second result is variation of Donoho-Strak's uncertainty principle for Weinstein transform, Let S,Σ⊂R\(_{+}^{d}\) and f∈L\(_{α}^{1}\) (R\(_{+}^{d}\))∩L\(_{α}^{2}\) (R\(_{+}^{d}\)). If f is (ε\(_{1}\),α)-timelimited on T and (ε\(_{2}\),α)-bandlimited on Σ, then μ\(_{α}\) (S) μ\(_{α}\) (Σ)≥(1-ε\(_{1}\))\(^{2}\) (1-ε\(_{2}^{2}\)). The third result is variation of the local uncertainty for Weinstein and Weinstein-Gabor transform.

The aim of the study is to determine the incidence, sociodemographic factors, indications, maternal characteristics and maternal and perinatal outcome of emergency obstetric hysterectomy. This is a retrospective hospital based study of the cases of emergency obstetric hysterectomy performed over a period of 5 years from Jan 2014 to November 2018. A total of 55 cases of emergency obstetric hysterectomy (EOH) were studied in the Department of Obstetrics and Gynecology, in a Al-Sadaqa Teaching Hospital, Aden. During the study period there were 55 emergency obstetric hysterectomies and 33903 deliveries, giving an incidence of 0.16% or 1.6/1000. The majority of the cases were unbooked (36.4%). It was more common in multipara and grandmultipara (57.3%). Ruptured uterus (60.0%) , atonics postpartum hemorrhage (10.9%) and morbidly adherent placenta (9.1%) were the common indications. Subtotal hysterectomy was performed in 69.1% of the cases and total hysterectomy in the rest. The perinatal mortality was (67.0%), and the maternal mortality was 1.8%. Emergency obstetric hysterectomy is a lifesaving procedure. Uterine rupture, uterine atonia and morbid adherent placenta are the leading indications for emergency obstetric hysterectomy.

However, while thyroid nodules are common, thyroid malignancy is relatively rare, constituting about 1% of all malignancies. The main point of the approach of the thyroid nodule is the detection of the malignant nodules and deciding for the surgical treatment. Ultrasonography (US) plays a crucial role in the diagnostic management of thyroid nodules. The aim was to assess the reliability of using hypoechoic, solid and ill-defined margin as independent predictors for the identification of malignant thyroid nodules on US. We retrospectively analysed the three suspicious US features of malignancy for 145 patients with 255 thyroid nodules who underwent thyroid resection. We used histological results as gold standard reference test. Of the 255 surgical resected nodules; hypoechoic nodules had a sensitivity of 66.7%, and positive predictive value (PPV) of 8.7%. Solid nodules had a sensitivity of 33.3% and PPV of 3.7%. Ill-defined margins nodules had a sensitivity of 66.7% and PPV of 6.9% in predicting malignancy. The present study adds further evidence on the poor PPV in our results, indicated, that individual US features are not reliable used as independent predictors for the identification of malignant potential thyroid nodules on US.

In recent years, there has been renewed interest in forensic sciences about forensic age and sex estimation in living subjects by means of radiology. Costal cartilage bridges, the sternum and the ribs play a key role in the biomechanics of the chest, and is known to be calcified in local regions with age. This study aims at finding out the patterns of costal cartilage calcification in relation to sex and age, and was conducted on digital thorax X-rays to test the usefulness of some radiological changes in the costal cartilage. A descriptive cross sectional study of 1371 radiographs of chest plates were collected from a Diagnostic Medical Center (DMC) in Aden city / Yemen, during the period January 2017 to December 2018, all data were analyzed for their calcification patterns according to the methods of McCormick et al. The incidence of calcification increased with the advancement of age and the earliest appearance of calcification in costal cartilage was seen at 18-19 years in both sexes but more significantly in females. The tendency of central calcification of cartilage was displayed in females, while the peripheral calcification preferred in males, and the mixed calcification seen in both sexes but more in males. It is safe to conclude that different patterns of calcification at rib cartilage observed in digital radiographs are sex specific, that is to say male subjects predominantly show peripheral pattern and female subjects predominantly show central pattern. Calcification of costal cartilage starts at the age of 18-19 years in both sexes and increases with age.

The present study evaluates the anti-diabetics and glycemic control of type 2 diabetic patients attending the out-patients clinics Aden. It is a cross-sectional study carried out in Aden Diabetic Center at Al-Gamhouria General Modern Hospital, Aden. Thirty two type-2-patients attended the center during the period from 15 January to 15 February 2018, using anti-diabetic drugs for more than one year, were included. Data were collected through direct interviews using a structured questionnaire, including patients characteristics as well as medical and medications characteristics. Blood samples were drawn to measure glycated hemoglobin HbA1c. Data were analyzed by using SPSS. (Version 22). Thirty seven and a half percent were females and 62.5% males. The mean age of the participants was 55 ±8.23 years. 56.2% of the patients showed good adherence to the exercise with the preponderance to the males, p=0.043. The mean BMI of the participants was 26.62± 3.89 Kg/m2, with half of them considered overweight (25-29.9 Kg/m2), while almost one fifth of the samples were obese. Half of the patients had hypertension and high cholesterol as comorbid conditions. The most frequent antidiabetic classes utilized by the patients were sulfonylureas, 62.5% and biguanides 62.5%. There was a limited use of DPP-4 inhibitors, sitagliptin and alogliptin (6.2%). 53.1% of the studied patients utilized monotherapy, followed by a combination of oral antidiabetics 37.55%, and a combination of oral antidiabetics and insulin (9.3%). The mean value of HbA1c of the samples studied was 9.65 ±2.33%. Only 12.5% of the patients had good glycemic control and 87.5% of the participants had HbA1c of ≥ 7 %. Almost forty percent of the patients with HbA1c ≥7% had cardiovascular diseases such as hypertension and higher cholesterol (p=0.019). In conclusion, the most frequent antidiabetic classes utilized by type-2-patients who attended outpatients clinics were sulfonylureas and biguanides with a tendency to use combination regimens. The majority of patients had poor glycemic control associated with cardiovascular morbidity. Attention should be given on the treatment regimens and dosage.
