In the context of modified gravity, we study the appearance of anisotropic compact stellar objects. The space–time geometry is characterized by the metric potentials, and to solve the field equations, we consider their specific form known as the Tolman–Kuchowicz space–time. The obtained solutions are free of singularities and satisfy all requirements for stellar objects. We consider the observational data for models of the stars Cen X-3, EXO 1785-248, and LMC X-4, and taking these data into account, we obtain the values of the physical parameters from the matching conditions for the interior Tolman–Kuchowicz space–time and the exterior Schwarzschild metric. In addition, we discuss some physical attributes of anisotropic compact stellar structures to verify the physical validity and stability of the proposed model. We perform a three-dimensional graphical analysis that allows obtaining a representation of the physical behavior of these compact objects. We note that all three compact objects correspond to physically accepted models. [ABSTRACT FROM AUTHOR]

In this study, electric quadrupole transition properties in some even-even Ti nuclei have been investigated by using different effective charges and interactions. In this respect, B(E2) transition rates, deformation parameters and intrinsic quadrupole moments have been calculated. In calculations, NuShellX code has been used to calculated one body matrix elements (OBDM). Theoretical calculations on these quantities have been compared with the experimental results, and it has been seen that theoretical values obtained by using the kb3 and vpnp interactions and Bohr Mottelson (B-M) and Standard (S-T) effective charges are close to the corresponding experimental results.

We study compact stars for f() gravity model using modified Tolman–Oppenheimer–Volkoff equation. Firstly, the hydrostatic equilibrium equations have been developed in the context of f() gravity. Secondly, the profiles of energy density, pressure and mass of stars are investigated through two different equations of state models, p = ωρ5/3 and p = a(ρ – 4b), ρ being the energy density, ω, a and b are the specific constants. For f() = α model with α being an arbitrary constant, the physical attributes of the compact objects have been discussed for the different values of model parameter α. It is concluded that in the framework of f() gravity, neutron and strange stars follow physically accepted patterns and the results agree with those already available in literature.

Strangles is the most common infectious and contagious disease of equines that affects upper respiratory tract. It is prevalent among the horses in sub-continent from pre partitioned times, an effective study to isolate locally prevalent strains in the area and study of factors affecting their consequent growth is essential. For the said purpose, twenty nasal swab samples were collected, ten from clinically sick and ten from apparently healthy horses with the history of disease. Isolated strains were undergone identification through biochemical and lancefield testing. Maximum in-vitro growth of Streptococcus equi (S. equi) is a critical factor for its cost effective bioceutics production. Effect of different factors like composition of medium such as (Tryptic Soy Broth (TSB), Nutrient Broth, Brain Heart Infusion broth (BHI), Reinforced Clostridial Medium (RCM) and Peptone Broth, pH (5, 7, 9), gas (oxygen availability, 5% CO2, aeration), horse serum (2%, 5%, 10%) and temperature (35°C, 37°C, 39°C) on growth of S. equi was therefore carried out. Growth was expressed in form of Colony Forming Units (CFU) which was converted into log values followed by statistical analysis. TSB among media, pH 7, CO2 5% gas, horse serum 5% and incubation temperature 37°C showed optimum growth of S. equi. [ABSTRACT FROM AUTHOR]

Among the established breeds of buffalo in Pakistan, the Nili-Ravi breed is dominant in the Punjab Province. The purpose of the study is to determine the chemical composition and fatty acid profile of buffalo milk. Milk is a complete food and contains all the nutritional components in balanced form. It helps to meet important nutritional needs of the human body. The buffaloes were divided into 3 groups on the basis of lactation period i.e. early, middle and late lactation. A total of 90 milk samples were obtained for analysis. Buffalo milk samples were analyzed for proximate analysis, parameters like fat, crude protein, lactose, ash, solids not fat (SNF), total solids (TS), pH and acidity were determined. Fatty acid profile of buffalo milk was determined by the method, Association of Office of Agricultural Chemists (AOAC, 2000). Milk fat content (%) was found to be significantly (p<0.05) lower in the early (6.52) and mid lactation (6.61) stages than the late lactation stage (6.85). The content of TS (%) was found to be significantly (p<0.05) higher in the late lactation (14.62 and 15.45) stage than the early (12.94 and 13.65)) and mid lactation (13.76 and 14.14) stages. In contrast, the content of total protein (4.31% to 4.78%), Solid not fat (8.40% to 8.70%), lactose (4.36% to 4.74%) and ash (0.18% to 0.19%) did not vary significantly among the different lactation stages. The values of Butyric acid, Caproic acid, Myristic acid, Stearic acid and Oleic acid showed significant increase towards end of lactation. These values of fatty acids also revealed that there is significant difference among the animals and lactation stages of Nili Ravi buffalo milk. Results showed that Capric acid, Lauric acid, Palmitic acid, Linoleic acid and Linolenic acid decreased in early to middle and increased towards end of lactation. [ABSTRACT FROM AUTHOR]

The worldwide rising incidence of cardiovascular diseases and the associated risk factors could be country or area specific. A case control study identifying important risk factors of myocardial infarction (MI) prevailing in the northern region of Bangladesh, was conducted in two major northern region hospitals, Rajshahi and Rangpur Medical College for a period of 6 months. Majority of the cases (66%) and controls (56%) were in the age range of 41 - 60 years. The proportion of male, married and urban residents were predominant in both the case and control group. The highest percentage of patients with MI were involved in business comparatively patients without MI. Clinical symptoms like chest pain, epigastric pain, breathlessness, dizziness and fatigue were observed to be somewhat higher in cases compared to controls. The logistic regression analysis showed that smoking habit, smokeless tobacco consumption, sedentary lifestyle and dyslipidemia were found independent predictors of MI in northern district patients with odds ratio (OR) (95% confidence interval) being 3.1 (1.2 to 3.7), 2.5 (1.0 to 3.5), 2.0 (1.1 to 3.6) and 2.3 (1.3 to 4.1), respectively.

The necessity of artificial irrigation due to arid climate of Pakistan and the shortage of canal water force the use of raw industrial effluents to grow crops, especially around big cities. The sewage contains heavy metal ions, including cadmium. The cultivars of the same crop do differ in their ability to absorb and translocate Cd. Four varieties of mungbean were investigated for their responses to Cd concentration, translocation from roots to shoots and bioaccumulation. The varieties NM-28, NM-54, NM-92 and NM-98 were tested in hydroponics with Cd application rates of 0.04, 0.08, 0.13, 0.17, 0.22 mM. For root dry weight varieties ranked in the order as NM-98 > NM-54 > NM-92 > NM-28, for shoot dry weight the order was NM-54 > NM-98 > NM-28 ~ NM-92. The NM-28 had the highest root Cd concentration followed by NM-92, NM-54 and NM-98. For shoot Cd concentration the varieties ranked as NM-28 > NM-54 > NM-92 > NM-98. All varieties retained most of the absorbed Cd in their roots and also these all have the ability to accumulate Cd in their roots and shoots. For root and shoot Cd bioaccumulation factor, the varieties were found to be in the decreasing order as NM-28 > NM-92 > NM-54 > NM- 98. From the results, NM-98 was found to be a good source for future mungbean breeding programs with the aim to produce low Cd accumulating varieties. It may also be recommended when mandatory to cultivate mungbean on slightly Cd contaminated areas while NM-28 seemed better to avoid under such conditions. [ABSTRACT FROM AUTHOR]
