Cooperatives, family farms and dragon‐head enterprises are emerging as new subjects of agriculture in C hina being promoted by the hinese government engines agricultural development. The current dynamics increasing capitalization has been characterized scholar P hilip H uang ‘Capitalization without Proletarianization’. Through case studies, we examine accumulation agriculture, well government's policy shift. We argue that capitalist exist production they come from above below. also shift...

A novel Ti-doped Sm-Mn mixed oxide (TiSmMnOx) was first designed for the selective catalytic reduction (SCR) of NOx with NH3 at a low temperature. The TiSmMnOx catalyst exhibited superior performance, in which conversion higher than 80% and N2 selectivity above 90% could be achieved wide-operating temperature window (60-225 °C). Specially, also showed high durability against large space velocity excellent SO2/H2O resistance. Ti incorporation can efficiently inhibit MnOx crystallization tune...

AbstractRural cooperatives appear to be flourishing in China. Yet this blossom has been controversial. Some contest whether specialized farmer should promoted. They are opposed the implications and consequences that derive from growth of such cooperatives. Many criticize most thus far developed 'fake' propose comprehensive peasant associations Japan, South Korea Taiwan as a model for emulation. These contestations about rural cooperatives, but also go quite beyond them. For those...

Lester Brown sounded an alarm in 1995: who will feed China? Against this backdrop, contribution examines China's dramatic turn from having been a soybean net exporter, up until the mid-1990s, to being biggest importer of genetically modified (GM) soybeans, since 2000. With growing imports, domestic production has experienced drastic fall, creating outcry about 'soybean crisis' China. This paper competing interpretations imports and how wide arrange heated debates critical reflections have...

Objective: To investigate the current beliefs and attitudes of nurses in Yunnan Province toward prescriptive authority, analyze influencing factors, provide evidence for future research policy formulation to support establishment nurses’ authority China. Method: A cross-sectional survey was conducted among 937 using Beliefs Attitudes Scale on Nurses’ Prescriptive Authority. The scale assessed four dimensions: perceived need, self-efficacy, benefits, barriers. Multiple linear regression...

The lamellar structure of (Bi,Sb)2(Te,Se)3 alloys makes it difficult to achieve isotropic thermoelectric properties in the directions along and perpendicular c-axis, especially for n-type samples. In this work, by introducing Cu polycrystalline CuxBi2Te2.7Se0.3 applying traditional synthesis process high-energy ball milling hot pressing, substantial enhancement figure merit zT is obtained both in-plane out-of-plane directions. intercalated not only provides electron transport media mobility...

p-Type (Bi, Sb)2Te3 alloys are attractive materials for near-room-temperature thermoelectric applications due to their high atomic masses and large spin-orbit interactions. However, narrow band gaps originating from interactions lead bipolar excitation, thereby limiting average thermoelectrics within a local temperature region (300-400 K). Here, we introduce Cu2Te into the Bi0.3Sb1.7Te3 (BST) lattice implement over wide range. The carrier concentration is synergistically modulated via Cu...

This study examines the development of ACS industry by taking Agricultural Machinery Service (AMS) as a case and discussing its impacts on small-scale household producers. Drawing upon theory 'appropriationism', this article shows that, replacing family labor input, AMS providers take share total agricultural income. As input decreases, producers are increasingly marginalized in distribution Even if still retain small plots land, they have lost control over farming process become subsumed to...

Summary Background In Taiwan, the prevalence of colorectal cancer has been increasing in recent decades. As a result, fecal occult blood test (FOBT) advocated and widely used for screening areas with limited colonoscopy capacity. The goal this study was to analyze sensitivity single immunochemical FOBT (I‐FOBT) correlate it results detecting neoplasia asymptomatic Taiwanese population. Methods Data were collected from health examinations conducted on adults older than 40 years who...

Abstract Aim Acute skin failure (ASF) can happen in critically ill patients. Therefore, adequate knowledge and skills regarding ASF are essential to manage this disorder. The aim of work was investigate the nurses' knowledge, attitude, practice (KAP) patients analyze its influencing factors intensive care unit. Methods A multicenter cross‐sectional study performed 10 tertiary hospitals March 2022. Eligible nurses received a survey with self‐designed questionnaire about their KAP ASF, which...

Abstract Difficulty in labour supervision has been considered to be one of the obstacles development capitalist agriculture. This paper presents two distinctive management strategies China's large‐scale agriculture, which contribute agrarian capitalism China. As shown these cases, agribusiness companies engaged grain crop production retreat from direct by outsourcing cultivation, while acquiring profits upstream and downstream activities. On other hand, producers, who are involved...

Identifying topological insulators and semimetals often focuses on their surface states, using spectroscopic methods such as angle-resolved photoemission spectroscopy or scanning tunneling microscopy. In contrast, studying the properties of from bulk-state transport is more accessible in most labs but seldom addressed. We show that, quantum limit a insulator, backscattering between only two states Fermi lowest Landau band can be forbidden at critical magnetic field. The conductivity...

With the rapid development of China's economy, demand for electricity has grown rapidly, leading to an urgent need sides participate in power responses. At present, researches on response (DR) mainly focus industrial and commercial users, but few household users. However, energy consumption accounts a high proportion great potential development. Therefore, this paper proposes strategy DR households based communities. First, concept clustering is put forward, which are aggregated into...

Abstract Taking the case of agricultural mechanization service industry as an example, this study discusses dynamics transformation China’s contracting in context scaling-up production, and how is reshaping small-scale household farming grain production. With accelerated growth farmland transfer, large-scale producers have been emerging rapidly different parts China past years. Since their demand for services from that producers, production has promoted services. Meanwhile, capital surplus...

Using a pure electric current to control kagome noncollinear antiferromagnets is promising in information storage and processing, but full description still lacking, particular, on intrinsic (i.e., no external magnetic fields or spin currents) spin-orbit torques. In this work, we self-consistently describe the relations among electronic structure, accumulations, torques dynamics of antiferromagnet driven by current. Our calculation can yield critical density comparable with those...

Tetradymite-structured chalcogenides, such as Bi 2 Te 3 and Sb , are quasi-two-dimensional (2D) layered compounds, which significant thermoelectric materials applied near room temperature. The intercalation of guest species in van der Waals (vdW) gap implemented for tunning properties has attracted much attention recent years. We attempt to insert Ga atoms the vdW between layers p-type 0.3 1.7 (BST) further improving thermoelectrics. vdW-related defects (including extrinsic interstitial...
