Five triorganotin（IV）（1-5） complexes of cinnamic acid, （Z）-2-acetamido-3-phenylacrylic acid, 3-methylbut-2-enoic acid, and 2,2-diphenylacetic acid have been synthesized and characterized by IH-13C-119Sn NMR, UV, and IR. The spectroscopic investigation demonstrated that the carboxylate group acts as a monodentate ligand in triorganotin（IV） compounds. Five triorganotin（IV） complexes were screened against the log phase culture of Mycobacterium tuberculosis H37Rv by colorimetric method using XTT dye as growth indicator. The MICs were found to he 0.08 and 1.25μg/mL.

Tectonic evolution of structures in Southern Sindh Monocline,Indus Basin,Pakistan formed in multi-extensional tectonic episodes of Indian Plate

引用

Geodesy and Geodynamics 2018年第5期9卷 358-366页

作者： Shabeer ahmed Sarfraz hussain Solangi Muhammad Saeed Khan Jadoon Adeel Nazeer Centre for Pure and Applied Geology University of Sindh Oil and Gas Development Company Limited

There are a number of structures and structural styles found in extensional tectonic settings of the world,and it is a big challenge to study the evolution of these structures. Evolution of structures formed in extensional tectonic settings have been studied by researchers on different extensional basins of the world. Southern Sindh Monocline lies on the western corner of Indian Plate and the tectonic history of Indian plate has also experienced different extensional episodes, and its journey rifted from Gondwanaland to its final welding to Asia. The aim of this study is to figure out the evolution of structures in the subsurface of Southern Sindh Monocline, Pakistan using the seismic data interpretation and flattening of horizons approach. Structures within the subsurface of Southern Sindh Monocline have been characterized by different tectonic episodes of Indian plate while rifting from Gondwanaland, rifting from other plates at different geological times and to its collision with the Asia. Basic structures within study area are classified into nine types while the structural styles have been classified into six types as horst and grabens, dominos, crotch, synthetic and antithetic, negative and flashlight structural style. The structures within the study area revealed evidence for three major structural episodes which can be characterized as Episode 1: Structures associated with rifting of Indian plate from Gondwanaland during Late Jurassic to Early Cretaceous, Episode 2: Modification and reactivation of previous structures while Madagascar rifted from Indian Plate during the Middle Cretaceous and during Episode 3: Inversion and reactivation of structures occurred when Indian Plate collided with Asia during Early Eocene.

Background: COVID-19 Pandemic is still circulating within the human population and proving to be a deadlier disease with a mortality rate ranging from 0.5% to 7%. Since COVID-19 is a highly transmissible disease;there is always a probability for its outward spread towards the general public and community from the hospitals and healthcare facilities where they come to seek treatment. Methodology: A prospective cohort study design was used, considering the limited available resources and time—a total of 200 healthcare workers (including doctors, nurses, para-medical staff, janitorial staff, reception staff & pharmacists) working in the OPDs of the two major public sector hospitals of Quetta were made part of this study. The study participants were selected using a simple random sampling technique and selection was made from the daily attendance register. The study participants from “Hospital-A” were first of all educated and trained on various COVID-19 IPC measures later on various COVID-19-IEC materials;written in simple Urdu language, were displayed clearly everywhere in the OPD. Similarly, handwashing stations along with hand sanitizers/soaps and surgical face masks were also made available free of cost for all the study participants of Hospital-A. Moreover the importance and effectiveness of COVID-19 IPC measures were continuously announced in the OPD gallery of Hospital-A, these announcements used simple wording in local languages (i.e., Urdu, Pashto, Balochi and Brahvi). On the other hand, in the OPD of “Hospital-B”, no such interventions were made. The study participants of both the hospitals were followed for one month and observations like which group showed more on-job noncompliance towards various COVID-19 IPC measures were recorded. The data was recorded on daily basis (from 1st May-to-31st May 2021) after observing the study participants for compliance towards using face masks, face shields,

Objective:To monitor the levels of aspartate transaminase (AST) and alanine transaminase (ALT) enzymes and testosterone hormone in months and seasons of ***: In this experiment, 20 (2.0-3.5 years old) Iraqi Awassi rams were used which were housed in semi opened shade. Blood samples (2-3 mL) were collected once a week for over period 12 mo. AST and ALT activities were measured by using colorimetric method, and testesterone analysis was performed with an automatic ***: The activities of both AST and ALT enzymes were increased significantly (P<0.05) during summer, on monthly basis, June showed the significantly highest value (P<0.05). The present study revealed that testosterone in autumn and summer was recorded significantly highest (P<0.05) in comparison with other seasons and on monthly basis the significant (P<0.05) highest level of testosterone was found between September and August ***: AST and ALT enzymes are the highest during summer, and on monthly basis they are the highest in June, while testosterone level is recorded highest in autumn season, and on monthly basis November shows the highest value.
