以价值共创为出发点,通过构建偏最小二乘法-结构方程模型(PLS-SEm)并验证,在线交互学习平台扮演着调节变量的角色。在线交互有助于用户社交价值的持续提升,进而增强用户粘性。在交互平台的调节作用下,通过直接影响和间接影响的对比揭示了行为参与和认知参与对于4个维度的价值产生影响;而情感参与仅对社交价值有局部影响。研究结论揭示了平台在线交互的内在机制,对于改进交互平台的设计具有积极作用。

Objective: To confirm the efficacy of non-antibiotic treatment with prostaglandin F2α(PGF2α) in dairy cows affected by severe clinical endometritis in (30±3) days in milk. methods: Cows with clinical endometritis Ⅲ (n=399) were aligned into three groups randomly. The first group (n=115) received PGF2α, the second group (n=84) received intrauterine infusion (IUI) of oxytetracycline 10% + PGF2α, and the third group (n=200) received IUI. Cows were inseminated following estrus. The pregnancy status, parity, calving and artificial insemination season, ovaries with corpus luteum at the time of treatment, dystocia, body condition score and treatment groups were included in data analysis. Results: Total pregnancy rate was 40.1% after the first insemination and 94.2% after the third insemination. Overall pregnancy rate of treated cows with IUI+PGF2α(84.5%) was significantly lower than the treated cows with PGF2α(98.3%) or IUI (96%) (Pminated cows in summer (14.3%) was lower in comparison with cows inseminated in spring (40.4%), fall (41.4%) and winter (51.7%) (Pmetritis in dairy cows with corpus luteum in comparison with other treatments.

The current research was carried out at Rakh Khaire Wala, which is well known as one of the most developed animal husbandry in Punjab, Pakistan. This location in the arid region, where sheep farming is a common practice, was selected for this study. The aim of the study was to determine and collect data on the mineral contents of forages or feedstuffs that are harvested and used in animal nutrition in the region, in order to gain information on the deficiency and/or excess of mineral levels for ruminants grazing therein, fed mainly with these feedstuffs. These pastures were visited twice during the study, in summer and winter, to collect samples in order to determine the effect of seasonal changes on the mineral contents of forages. In each location, samples from the available forages were collected. Forage samples were analyzed in order to determine the Ca, mg, Na, K, Fe, Cu, Zn and mn levels using an Atomic Absorption Spectrophotometer. These results show that pasture grasses/forages had sufficient levels of K, Ca, mg, mn and Zn to meet requirements of ruminant animals, but the occurrence of marginal to deficient supplies of Na, and Cu appear very likely. There is an urgent requirement for experimentation on supplementation regimes involving these minerals, so that appropriate recommendations can be formulated.

Currently, there are a limited number of dynamic models available for braided composite plates with large overall motions, despite the incorporation of three-dimensional(3D) braided composites into rotating blade components. In this paper, a dynamic model of 3D 4-directional braided composite thin plates considering braiding directions is established. Based on Kirchhoff's plate assumptions, the displacement variables of the plate are expressed. By incorporating the braiding directions into the constitutive equation of the braided composites, the dynamic model of the plate considering braiding directions is obtained. The effects of the speeds, braiding directions, and braided angles on the responses of the plate with fixed-axis rotation and translational motion, respectively, are investigated. This paper presents a dynamic theory for calculating the deformation of 3D braided composite structures undergoing both translational and rotational motions. It also provides a simulation method for investigating the dynamic behavior of non-isotropic material plates in various applications.

The aim of this study was to compare the quality characteristics and mineral content of the fiber from male and female cashmere goats raised under different management systems. male and female Raeini cashmere goats （〈1.5 years of age, n=48） were selected from flocks raised at a government breeding station or raised commercially under either rural or nomadic conditions. The staple length, cashmere fiber diameter, coefficient of variation for fiber diameter, percentage of cashmere in a fleece, percentage of guard hair in a fleece and cashmere tenacity averaged 4.6 ±0.1 cm, 18.0 ±0.1 um, 20.9±0.4%, 66.1 ± 1.5%, 33.8± 1.5% and 1.8±0.2 gf/tex, respectively. The sulfur, copper and zinc content of the cashmere averaged 2.8 ± 0.1%, 0.00065 ± 0.00002% and 0.01276 ± 0.00025%, respectively. Rearing method significantly affected staple length, coefficient of variation of fiber diameter, cashmere tenacity and copper content. males had a higher coefficient of variation of fiber diameter and cashmere tenacity than females （P 〈 0.05）.
