Active Landslide Detection Based on Sentinel-1 Data and InSAR Technology in Zhouqu County, Gansu Province, Northwest China

Abstract Background Little information about the prevalence of gastrointestinal parasites in yaks (Bos grunniens) in northwest China is available. Therefore, the objective of the study was to quantify faecal egg counts of gastrointestinal parasites (helminths and coccidia) in free-range yaks from Gannan Tibetan Autonomous Prefecture, Gansu Province, Northwest China. Results Parasites were detected in 290 of 733 (39.56%) faecal samples. The results showed that Strongylidae, Trichuris spp. and Eimeria spp. were detected all year round, Strongyloides papillosus was detected in autumn and summer, and Nematodirus spp. was detected in both autumn and spring. In contrast, Fasciola spp. was only detected in spring. The prevalence rates of parasitic infections in different seasons were significantly different. Conclusions To our knowledge, this is the first investigation of gastrointestinal parasites in yaks (Bos grunniens) in Gansu, China. The results demonstrated a high prevalence of gastrointestinal parasitic infections, specifically GN infections, in yaks in GTAP and these infections can cause economic losses to the local cattle industry.

Different Seasons

Chlamydia abortus, an important pathogen in a variety of animals, is associated with abortion in sheep. In the present study, 1732 blood samples, collected from Tibetan sheep between June 2013 and April 2014, were examined by the indirect hemagglutination (IHA) test, aiming to evaluate the seroprevalence and risk factors ofC. abortusinfection in Tibetan sheep. 323 of 1732 (18.65%) samples were seropositive forC. abortusantibodies at the cut-off of 1 : 16. A multivariate logistic regression analysis was used to evaluate the risk factors associated with seroprevalence, which could provide foundation to prevent and controlC. abortusinfection in Tibetan sheep. Gender of Tibetan sheep was left out of the final model because it is not significant in the logistic regression analysis (P>0.05). Region, season, and age were considered as major risk factors associated withC. abortusinfection in Tibetan sheep. Our study revealed a widespread and high prevalence ofC. abortusinfection in Tibetan sheep in Gansu province, northwest China, with higher exposure risk in different seasons and ages and distinct geographical distribution.

The Impact

Rural living conditions (RLCs) in China are influential on the overall development and stability of regions, particularly for populations in distant poverty-stricken villages. This paper takes 16 villages of Chedao town in Gansu province, Northwest China (NWC) as our case study. Using data from the Poverty Alleviation and Assistance (PAA) project launched by Lanzhou University in June 2017, and the perceptions of residents of Chedao, we pinpoint RLC changes in the targeted poverty alleviation (TPA) process. The three main results show that: (1) From the residents’ perceptions, the impact of alleviation measures on RLC is mainly reflected in improved housing conditions, infrastructure, and public services. We find no significant effect on cultural conditions. However, eco-environmental conditions have obviously weakened. (2) Housing size, accessibility, distance to shops, and safe drinking water are the most significant factors in housing conditions, infrastructure, public services, and eco-environmental conditions, respectively. (3) Out of the different levels of rural poverty households (RPHs), severe rurality villages are more strongly aware of the positive changes in RLC than residents of mild rurality villages. Moreover, in residents’ view, housing conditions are most improved in severe rurality villages, infrastructure is most improved in moderate rurality villages, and public services are most improved in mild rurality villages. Eco-environmental conditions worsen across all levels. Our findings shed light on the perceptions of residents on changes occurring in rural living conditions, and provide a basis for subsequent studies of RLC in Northwest China.

In the highest soil erosion regions of arid and semiarid northwest China, water resource deficits and farmland misuse have further exacerbated soil degradation. Therefore, understanding how farmers in diverse agroclimatic zones perceive and respond to different conservation practices is important to the implementation of sustainable agriculture practices (SAPs). To this end, this study uses a best–worst scaling approach to examine the adoption preferences for nine SAPs among grain and cash crop farmers and investigates the influence of farm and climatic characteristics on adoption preferences based on a face to face survey of 554 households in Gansu province, which is classified as an arid and semiarid area in northwest China. Both grain and cash crop farmers had stronger preferences for the practices of using organic instead of chemical fertilizers and of improving irrigation practices. In addition, while cash crop farmers also had strong preferences for cover crop-related practices, they preferred long-term fallows least. Household income, livestock, and precipitation influence the potential perceived importance of SAPs. The different perceived importance of these practices suggests new possible combinations or packages for a sustainable agriculture program during the cropping structure adjustment in Gansu.

Toxoplasma Gondii Infection

AbstractPrevalence of antibodies to Toxoplasma gondii and risk factors with infection were assessed in dairy cattle from Gansu Province and Ningxia Hui Autonomous Region (NXHAR), northwest China. In total, 1657 serum samples were collected and assayed by the modified agglutination test. The overall seroprevalence was 4.83% at a 1:100 cut-off, with titers of 1:100 in 72, 1:200 in 4, 1:400 in 4. Among the risk factors examined, no statistically significant difference was observed between T. gondii seroprevalence and regions or age of dairy cattle in the logistic regression analysis (P>0.05) and left out of the final model. However, numbers of pregnancies of dairy cattle was considered as main risk factor associated with T. gondii infection. Dairy cattle in nulliparity group (8.89%) had 6 times (OR=6.31, 95% CI, 2.69-14.83, P<0.001) higher risk of being seropositive compared to dairy cattle in 3 or above 3 pregnancies group (1.52%), followed by 1 pregnancy group (4.27%) had nearly 3 times (OR=2.89, 95% CI, 1.11-7.52, P = 0.03) higher risk of being seropositive compared to dairy cattle in 3 or above 3 pregnancies group, although no statistical difference was found between 2 pregnancies group and 3 or above 3 pregnancies group (P = 0.70). The results of this survey indicated the presence of T. gondii infection in dairy cattle in Gansu Province and NXHAR, which enriches the epidemiological data of T. gondii infection in dairy cattle in China, and is helpful to strengthen prevention and control of T. gondii infection in dairy cattle in these two regions.

The purpose of this paper was to establish norm about the scale of self-concept on junior middle school students in the northwest China region by using the self-concept scale on junior middle school students in the northwest China region. The random samples of 1681 from Shannxi province, Gansu province, Ningxia autonomous region, Xinjiang autonomous region carried out the study. The results of the F test showed that there were significant differences in grade, gender, gender and grade interaction effect on most dimensions of self-concept. The study gave the norm of 10 factors about liberal arts self-concept, science self-concept, arts self-concept, family self-concept, friends self-concept, self-worth, mental and physical self-concept, appearance self-concept, conscience, honesty and second-order factors about academic self-concept, interpersonal self-concept, own self-concept, moral self-concept for the male and female students.
