This work performs a comparative numerical study of the impurity average self-frequency w in an unconventional superconducting alloy with non-magnetic impurities. Two methods are used: the Levenberg-Marquardt algorithm as a nonlinear minimization problem, and a fixed-point iteration procedure. The unconventional superconducting renormalized by impurities w is a self-consistent complex nonlinear equation with two varying parameters: the impurity concentration ?+ and the strength of the impurities c, for which its numerical solution is a computational challenge. This study uses an order parameter that corresponds to the high-temperature superconducting ceramics (HTS) with a wellestablished gap symmetry. The results reveal the computational efficiency of the non-linear minimization technique by improving the calculations of the w computation when using a two-dimensional parameter space (?+, c), particularly in the unitary regime, where the imaginary part of w is a complicated expression of those parameters; this allows to enhance the study of the universal behavior of this particular quantum mechanical state.

Benchmarking the composition of bismuth (Bi), thorium (Th) and uranium (U) in breakfast cereals has not been previously documented and could be considered a baseline study in this domain of research. Detection of naturally occurring actinides is generally below the lower limit of detection in most contemporary methods of analysis. However, hyphenated plasma mass spectrometry (ICP-MS) has the capability of achieving a limit of detection in the ng/L (ppt) range and is, therefore, favorable for investigating levels of noxious metals at ultra-low levels in foodstuffs. Bismuth, thorium and uranium rarely occur at appreciable levels in most foodstuffs and their detection would be a useful contribution to knowledge related to nutrients. For the metals of interest we detected the following range of concentrations in breakfast cereals: Bi: 3-14 ?g/L; Th: 6-100 ?g/L and U: 1-15 ?g/L. The elemental profiles of these metals are discussed and the feasibility of employing the data for fingerprinting studies is reported. There are no wellknown toxicological guidelines for these elements and their health effects form part of ongoing studies in clinical research. Our study could make a significant contribution to sustainability and current nutritional research.

Information Systems (IS) organizations are experiencing a mounting pressure to contribute organizational success and to secure information asset, therefore, protection of information assets has become a paramount concern in IS organizations. IS organizations recognize the importance of evaluation of information systems and implemented controls so that any risk either could be removed or mitigated for their information asset and infrastructure by implementing appropriate measures. The aim of this paper is to analyze, explain and demonstrate the effectiveness of software and hardware acquisition controls in IS organizations to ensure optimum benefits in the organizations. Also, the study determines that whether organizations are careful in implementing the preventative controls and how effectively the organizations benefit from the controls for software and hardware acquisition. In order to complete the current study data has been collected from different financial organizations, which have an existing IS audit function in place. The data has been analyzed and approach used by these organizations has been evaluated in view of specific industry standards of IS audit and control set by organizations

It is known that every completely j-simple semigroup is isomorphic to a normalized Rees matrix semigroup over a ? - monoid. Utilizing this result, we show that the homomorphism of a completely j-simple semigroup is a good homomorphism. Consequently, we give a construction theorem of homomorphisms between completely j-simple semigroups. This result strengthens the one given by Ren et al. (2018) on homomorphisms of completely j-simple semigroups

Parasitoids are the most widely used group of natural enemies in biological control programs of insect pests especially for aphid species. Among the aphid parasitoids, Diaeretiella rapae is one of the most important to parasitize the aphid species Brevicoryne brassicae. The present study was done under laboratory condition (25±2 ºC temperature and 65- 70% R.H.) to assess the biotic potential of D. rapae on B. brassicae. We used host densities of 10, 20, 40, 80 and 120 aphids per cage. For each host density only two couples of male and female of D. rapae were released. Results showed that the highest parasitism rate (40.95%) was observed at the lowest host density (10 aphids), while minimum parasitism (23.41%) was observed at the highest host density (120 aphids). Parasitism rates of 36.08%, 33.63% and 31.76% were observed in host densities of 20, 40 and 80 aphids, respectively. The percent emergence of adult D. rapae from each host density of 10, 20, 40, 80 and 120 aphids was 81.17%, 69.44%, 63.34%, 48.42% and 44.76% respectively. The coefficients of determination (R2) values for percent parasitism and adult emergence were 91.95% and 90.24%, respectively. Our f0069ndings revealed that an increase in host density decreased the parasitic potential as well as the percent emergence of the aphid parasitoid

In the present paper following the previous work (Walker and Contreras, 2002; Walker, 1980; Walker et al., 2001; Contreras, 2006) we calculate the jumps for the thermal expansion ??xy, the specific heat C?xy, and the elastic compliance ????? ??? in the basal plane of Sr2RuO4. We use here the 4th rank tensor notation because of the Voigt notation, where the stress and strain are treated differently. Henceforth, we clarify some issues regarding a Ginzburg-Landau analysis suitable to explain the sound speed experiments (Lupien, 2002), and partially the strain experiments (Hicks et al., 2014; Steppke et al., 2017) in strontium ruthenate. We continue to propose the following: (1) the discontinuity in the elastic constant Cxyxy of the tetragonal crystal Sr2RuO4 gives an unambiguous experimental evidence that the Sr2RuO4 superconducting order parameter ? has two components with a broken time-reversal symmetry state, and (2) the ? band couples the anisotropic electron-phonon interaction to the [xy] in-plane shear stress in Sr2RuO4 (Walker et al., 2001; Contreras, 2006)

Field surveys were undertaken from 2015 to 2019 in major ecological zones of the Balochistan province to collect data on the distribution and status of its wildlife. Based on five years field observations, 92 species of mammals, 373 species of birds, 120 species of reptiles and seven species of amphibians were documented. The present study gives an update list of Wildlife Protected Areas of the Province, the list of Threatened/Near-threatened species, the important wildlife hotspots, important ecotourism sites and key/peculiar of wildlife species. In regard to the Threatened/Naer-threatened species of wildlife, among mammals four species are Endangered (EN), eight species are Vulnerable (VU) and three species are Near-threatened (NT). Among birds, two species are Critically Endangered (CR), four species are EN, three species are Vulnerable and 15 species are Near-threatened. Among reptiles, one species is Critically Endangered, one species is Endangered and six species are Vulnerable. The threats along with Protected Areas Management issues have also been identified and Priority Actions for the conservation and management of wildlife and its habitats have been suggested. The achievements made so far in the Province have been highlighted for awareness of the scientific community and for appreciating the commendable efforts in the Province made so far.

Hormones involved in the regulation of carbohydrate metabolism in amphibians have been shown to exhibit seasonal variable effects. The present study investigated the effects of adrenaline, glucagon, and cortisol on blood glucose level in the Common African toad Bufo regularis during three rainy and dry seasons. Adult toads of either sex weighing between 70-100g were randomly selected and used in the experimental study. Each animal was anesthetized with sodium pentobarbitone 3mg/100g body weight given intraperitoneally. The truncus arteriosus was used for blood sampling while the anterior abdominal vein was cannulated for injection of drugs. Blood sample was taken from truncus arteriosus to determine blood glucose using the modified glucose oxidase method. Adrenaline (10?g/kg) produced 70% increase in blood glucose during rainy season and 92% increase in blood glucose during dry season. Glucagon (10?g/kg) caused 102% increase in blood glucose during the rainy season and 88% increase in blood glucose during the dry season while cortisol (10?g/g) caused delayed but 50% increase in blood glucose during the rainy season and 61% increase in blood glucose during the dry season. The results of this study suggest that seasonal variation exists in the blood glucose response to adrenaline, glucagon and cortisol in the Bufo regularis. Therefore, seasonal changes should be taken into consideration in hormonal studies involving amphibians such as the B. regularis
