Climate change is rapidly warming high latitude and elevation regions influencing plant community composition. Changes in vegetation composition have motivated the coordination of ecological monitoring networks across Arctic, including International Tundra Experiment. We established a long-term passive experiment using open-top chambers, which includes five distinct communities (Dry Heath; Tuss...
The lack of women’s presence in firms’ top management positions reflects gender equity problems, especially South Asia, including Pakistan, and contours a firm’s financial behavior. Based on the underpinning conceptual framework developed by combination fourteen femininity theories, current study investigates induction its impact We collected data from annual reports 60 non-financial firms list...
effect of different co2 concentrations on sucrose metabolizing enzymes and on carbohydrate metabolism was studied for eight blackgram (vigna mungo l. hepper) genotypes grown in open top chambers under ambient (380 µmol mol-1) vs. elevated co2 (550 and 700 µmol mol-1) levels. the higher acid invertase activity over neutral invertase indicated the major role of acid invertase in sucrose breakdown...
Development of a dual-display handheld optical coherence tomography (OCT) system for retina and optic-nerve-head diagnosis beyond the volunteer motion constraints is reported. The developed system is portable and easily movable, containing the compact portable OCT system that includes the handheld probe and computer. Eye posterior chambers were diagnosed using the handheld probe, and the probe ...
The Resistive Plate Chambers (RPC) detector of the CMS experiment at the LHC proton collider (CERN, Switzerland) will employ an online gas analysis and monitoring system of the freon-based gas mixture used. We give an overview of the CMS RPC gas system, describe the project parameters and first results on gas-chromatograph analysis. Finally, we report on preliminary results for a set of monitor...
Microbes play an important role in the carbon cycle and nutrient flow of soil ecosystem. However, response microbial activities to long-term warming over decades is poorly understood. To determine how changes ecoenzyme activity limitation, we conducted a long-term, 21 years, experiment, on Qinghai—Tibet Plateau. We selected typical grass- shrub-covered plots, used fiberglass open-top chambers (...
