Wheat is an important source of energy and nutrition including antioxidants having health benefits to humans. In this investigation, 19 12 prominent wheat genotypes grown (during cropping season 2019-20) at three locations in two production environments representing North-Western Plains Zone (NWPZ) Central (CZ), respectively, were used for evaluating their antioxidant potential. There was a sig...
The terms “Pink Puffers” and “Blue Bloaters” have been around for many years. They are used in a colloquial sense by speleologists to describe how cavers react to an elevated concentration of carbon dioxide (CO2) and reduced oxygen (O2) in a cave’s “foul air” atmosphere. Foul air is only found in a small number of Australian caves and is defined as having a noticeable abnormal physiological eff...
To study on the characteristics of the vibration signals of coal and stone hitting the armor plate during caving, a hybrid algorithm based on first order forward difference and wavelet transform modulusmaxima method is presented which can be used in the longwall top coal face. First, in order to reduce the noise interference, the pre-processing of the vibration signals is done by the first orde...
Two antigen detection systems (MicroTrak [MT], Syva Co., Palo Alto, Calif.; and Chlamydiazyme [CZ], Abbott Laboratories, North Chicago, Ill.) were compared with semiquantitative culture for diagnosis of chlamydial infection in 1,059 patients. Cultures were done on microtiter plates and blind passaged once. Culture-negative but CZ- or MT-positive specimens were recultured. True positives were po...
Based on the engineering background of Meishan iron mine with sublevel caving (SLC) method, in this work, we adopted method for identifying shape mined orebody (the original location blasted slice), which analyzed and determined reasonable stope structure parameters. In field test, markers were arranged slice, was measured by situ tests, reliable data achieved. The obtained through test when wi...

Purpose. Determining the actual dimensions of protecting and crown pillars ore bodies by seismic survey assessing possibility rock mass collapse fracturing at lower levels Zhairemskoye field. Methods. An integrated approach is used, which involves analysis complete development during combined mining. To determine geological strength index (GSI) rating (RMR), structure studied, as well executed ...
The paper presents a part of the results obtained in a complex research project on Romanian Grey Steppe breed, owner of some remarkable qualities such as hardiness, longevity, adaptability, special resistance to ban weather and diseases and included in the genetic fund (G.D. no. 822/2008.) from Romania. Following the researches effectuated, we identified alleles of six loci, codifying the six t...
The factors that control the partial pressure of carbon dioxide ( p CO 2 ) in Pacific sector Southern Ocean were investigated April 2018, onboard icebreaker, ARAON. mean (± 1σ) sea surface was estimated to be 431 ± 6 μatm north Ross Sea (NRS), 403 18 Amundsen–Bellingshausen (ABS), and 426 16 western Antarctic Peninsula Weddell (WAP/WS). controlling for NRS appeared meridionally different based ...
Hard rock aquifers (HRAs) in West Africa (WA) are located within a thick regolith layer. The representation of tropical integrated hydrological models lacks consensus on aquifer geometries and parameter ranges. Our main objective was to determine the knowledge requirements saturated hydraulic conductivity (Ks) model critical zone (CZ) HRAs WA. A parametric sensitivity analysis with focus Ks het...
