Effectiveness of the use of biologically active substances (bas) at different levels of mineral nutrition of beans (paseolus vulgaris l.) grown under condition Afghanistan
This experiment was carried out in experimental field of Alberoni University of Kapisa province of Afghanistan, in the summer of 2022 and 2023. The experiment was carried out in the form of randomized complete block design with three replications. The treatment included three different levels nitrogen (N30, N45, N60), phosphorus (P20, P40, P60), potassium (K10, K20, K30), and one level of gibberellic acid GA3 (G1 = 100ppm). This study flowing the weight of 1000-grain, Grain yield, biological yield and straw yield were affected by experimental treatments. In evaluating the effects, the highest rate of studies traits was obtained at yield parameters in bean. Moreover, due to the application of 100ppm gibberellic acid with N60, P60, K30 kg/ha the highest rate was obtained from weight of 1000 grain, Grain yield and biological yield, but in the parameter of straw yield was earned low amount then T4 during 2022 and 2023 year. In addition, investigating the effect of gibberellic acid showed that the highest rate of grain yield was obtained at T7
The influence of agrotechnologies of organic farming on the content of humus, phosphorus and potassium in the soil
Abstract Organic agriculture is becoming an increasingly popular direction in modern agriculture. At the same time, some researchers and practitioners still have doubts about the ability of this technology to maintain the balance of nutrients in the soil. The article is a contribution to the study of the influence of long-term organic farming on agrochemical soil parameters. The aim of the study was to study the influence of organic farming technology on the content of humus, mobile forms of potassium and mobile forms of phosphorus in the soil of the most important components for fertility – humus, mobile forms of potassium and mobile forms of phosphorus in the non-carbonate chernozems of Western Siberia. The chernozems of Western Siberia are characterized by a high content of humus and nutrients, have optimal properties for agricultural crops. A statistically processed comparison of the quantitative content of humus, mobile forms of potassium and mobile forms of phosphorus in fields with long-term use of organic farming technology, and in similar fields where this technology was not used, was carried out. The article includes a brief geographical, geological, climatic characteristics of the place of the experiment, a description of the applied agricultural technologies and fertilizers. As a result, it was found that the use of organic farming technology has a positive effect on the state of soils, which is confirmed by an increase in the content of humus, mobile forms of potassium and mobile forms of phosphorus
The optical module of the Baikal deep underwater neutrino telescope
A deep underwater Cherenkov telescope has been operating since 1993 in stages
of growing size at 1.1 km depth in Lake Baikal. The key component of the
telescope is the Optical Module (OM) which houses the highly sensitive
phototube QUASAR-370. We describe design and parameters of the QUASAR-370, the
layout of the optical module, the front-end electronics and the calibration
procedures, and present selected results from the five-year operation
underwater. Also, future developments with respect to a telescope consisting
from several thousand OMs are discussed.Comment: 30 pages, 24 figure

Baikal-GVD
We present the status of the Gigaton Volume Detector in Lake Baikal (Baikal-GVD) designed for the detection of high energy neutrinos of astrophysical origin. The telescope consists of functionally independent clusters, sub-arrays of optical modules (OMs), which are connected to shore by individual electro-optical cables. During 2015 the GVD demonstration cluster, comprising 192 OMs, has been successfully operated in Lake Baikal. In 2016 this array was upgraded to baseline configuration of GVD cluster with 288 OMs arranged on eight vertical strings. Thus the instrumented water volume has been increased up to about 5.9 Mtons. The array was commissioned in early April 2016 and takes data since then. We describe the configuration and design of the 2016 array. Preliminary results obtained with data recorded in 2015 are also discussed
The Baikal Deep Underwater Neutrino Experiment: Results, Status, Future
We review the present status of the Baikal Underwater Neutrino Experiment and
present results obtained with the various stages of the stepwise increasing
detector: NT-36 (1993-95), NT-72 (1995-96) and NT-96 (1996-97). Results cover
atmospheric muons, first clear neutrino events, search for neutrinos from WIMP
annihilation in the center of the Earth, search for magnetic monopoles, and --
far from astroparticle physics -- limnology.Comment: Talk given at the Int. School on Nuclear Physics, Erice, Sept.199
Diplomacy methods of the zhango period (on the example of the activities of Su Qin and Zhang Yi)
The article is devoted to the development of the diplomacy of Ancient China during the Warring States (Zhanguo). The material of the study were texts in Chinese, as well as works in Russian and Chinese. The article notes the growing role of the personality of the ambassador, diplomat. Particular attention is paid to the activities of two famous diplomats and strategists of the time, Su Qin and Zhang Yi. Su Qin is considered the founder of the idea of uniting the six kingdoms (Wei, Chu, Han, Qi, Zhao, Yan) into the anti-Qin alliance “vertically” (“hezong”) The merit of Zhang Yi is to create a pro-Qin alliance “horizontally” (“lianheng”) with the same kingdoms: Wei, Chu, Qi, Han, Zhao, Yan. The article provides a comparative analysis of the diplomatic activities of strategists Su Qin and Zhang I. The novelty of the study is that the activities of famous diplomats are examined through their use of “stratagems”. © 2021, Rossiiskaya Akademiya Nauk, Institut Istorii (Russian Academy of Sciences, Institute of General Hist.

Core-shell nanosize particles Mg@Ni: synthesis and properties
В данной работе исследованы частицы со структурой металлическое ядро (магний) – металлическая оболочка (никель), полученные в металлсодержащей ВЧ плазме дугового разряда. Методами рентгенофазового анализа, рентгенофлуоресцентного анализ, сканирующей электронной микроскопии показано, что частицы имеют сплошную никелевую оболочку, что также косвенно подтверждается сравнением результатов гидрирования частиц Mg и Mg@Ni. С помощью измерений объёмной намагниченности установлено, что размер наибольшая часть частиц имеет толщину оболочек не более 22 нм
