Long-term (13 years) impact of organic and conventional farming on soil physical properties was evaluated under a rice (Oryza sativa L.) – wheat (Triticum aestivum cropping system in sandy clay loam at New Delhi. The treatments included unfertilized control (T1), conventionally managed (T2) five (T3: FYM @ 10 t/ha to wheat, T4: SGM for LGLM T5: + BGA Azotobacter T6: T7: wheat). application amen...
Starting in 1998, the electricity market in England and Wales will be opened up to full competition, and all consumers will be allowed to choose their electricity supplier. This promises to result in lower prices, but there will be additional transactions costs exceeding £100 million a year for the first five years. Relative to a counterfactual without competition, there are likely to be large ...
This paper is devoted to the study of products of classes of right $S$-posets possessing one of the flatness properties and preservation of such properties under products. Specifically, we characterize a pomonoid $S$ over which its nonempty products as right $S$-posets satisfy some known flatness properties. Generalizing this results, we investigate products of right $S$-posets satisfying Condi...
Abstract A framework for a IoT-based local landslide early warning system (Lo-LEWS) has been proposed. Monitoring, modelling, forecasting and represent the main phases of proposed framework. In this study, first two have applied to capture hydrological behaviour natural unsaturated slope located adjacent railway track in Eastern Norway. The is monitored stability kept under frequent observation...
BACKGROUND Depression is associated with physical inactivity, which may mediate the relationship between depression and a range of chronic physical health conditions. However, few interventions have combined a psychological intervention for depression with behaviour change techniques, such as behavioural activation (BA), to promote increased physical activity. METHODS To determine procedural ...
[1] The center of Hurricane Felix passed 85 km to the southwest of the Bermuda Testbed Mooring (BTM; 31 440N, 64 100W) site on 15 August 1995. Data collected in the upper ocean from the BTM during this encounter provide a rare opportunity to investigate the physical processes that occur in a hurricane’s wake. Data analyses indicate that the storm caused a large increase in kinetic energy at nea...
Sustainable soil management with the appropriate understanding of characteristics is vital in maintaining and improving agriculture management. The objectives present study are to characterize spatial variability using GIS technique used agglomerative hierarchical clustering (AHC) for delineation zones (MZs) precision agriculture. A total 111 samples were collected from 37 profiles systematic d...
در پژوهش حاضر از نرمافزار HYDRUS-2D/3D برای برآورد پارامترهای هیدرولیکی مدل ونگنوختن-معلم در سه بافت متفاوت خاک به روش معکوس، با استفاده از دادههای نفوذسنج استوانههای دوگانه، استفاده شد. برای این منظور نه گزینه با تعداد متفاوت پارامترهای هیدرولیکی انتخابشده برای فرایند بهینهسازی (5، 4 و 3 پارامتر)، در سه گروه مجزا تعریف شد. در گروه اول تنها از دادههای نفوذ تجمعی اندازهگیریشده به عنوان ...
This article investigates the regulation of angular speed an electric drive (ED) with a pulse-width converter (PWC) and direct current motor (DC motor) independent excitation (NV) when controlled in closed-loop system. A proportional-integral (PI) -regulator was used as regulator velocity. To analyze processes SHIP-DPT system, methods simulation are used. The principle operation control from PW...
