Conservation tillage is commonly used in regions affected by water and wind erosion. To understand the effects of conservation tillage on soil nutrients and yield, a long-term experiment was set up in a region affected by water and wind erosion on the Loess Plateau. The treatments used were traditional tillage (CK), no tillage (NT), straw mulching (SM), plastic-film mulching (PM), ridging and p...

This study aims to examine the basic mathematical knowledge of primary education student teachers according Ck¢ theory. The data this qualitative is collected through exams applied and clinical interviews undertaken with teachers. To determine conceptions teachers, examinations on subjects Sets, Equations, Functions, Numbers were 61 classroom , then 26 them interviewed. A detailed analysis exam...

The effects of biochar application on dry direct-seeded rice paddies remains unclear. Therefore, we applied to paddy fields over 3 consecutive years assess its soil physicochemical properties and bacterial diversity (conventional fertilization [CK]; + conventional [BC]). BC increased the content 0.25–5 mm water-stable aggregate particles, but decreased that <0.25 aggregates. At different dep...

OBJECTIVE Oxidative stress is implicated in the initiation and progression of congestive heart failure, but the putative reactive species and cellular targets involved remain undefined. We have previously shown that peroxynitrite (ONOO(-), an aggressive biological oxidant and nitrating agent) potently inhibits myofibrillar creatine kinase (MM-CK), a critical controller of contractility known to...

This study was conducted to explore the effects of heat stress (HS) and γ-aminobutyric acid (GABA) on antioxidation in intestinal mucosa of Wenchang chickens. One-day-old male chickens were randomly divided into GABA and control (CK) groups after 15 days feeding. The chicken from GABA group fed with 0.2 ml GABA solution and the chicken from CK group fed with 0.2 ml normal saline daily. At the a...

Dissolved organic matter (DOM) is the immediate energy, carbon, and other nutrient substrates for microbial growth and, therefore, plays an essential role in agroecosystem biochemical processes. The aim of this study was to elucidate interrelationships among watermelon growth, DOM chemical characteristics, content, functional diversity soilless growing substrates. We analyzed effect no fertiliz...

The importance of content knowledge on proficiency in teaching practices is well documented (Borko et al., 1992; Shulman, 1986). But is this statement completely unimpeachable? Are there drawbacks for teaching that are specifically due to subject matter expertise? In this paper we draw on evidence from mathematics and language arts education to show ways that advanced knowledge in a content are...

The exchange of semantically rich digital content over distributed applications facilitates knowledge exchanges in mixed human / machine environments as envisaged by scenarios within the scope of Ambient Intelligence and Semantic Web. For this class of domain, we introduce a semantically annotated data structure (KCO) and a distributed, layered protocol-based system architecture (KCCA, KCTP) th...

Deficiency of dystrophin in skeletal muscles is supposed to be responsible for all the symptoms associated with Duchenne dystrophy (DMD) and Becker dystrophy (BMD). The dystrophin-deficient mdx mice, however, are clinically almost asymptomatic. Hence, other factor(s) might be responsible for the muscle pathology in DMD and BDM. As sulfhydryl groups are involved in maintaining the structure of m...
