Statistics show that, about 157 oil and gas fields were found in crystallized bedrocks, with oil reserves of 5048x 10^8 t, and gas reserves of 2681x10^8m3. Among the discovered industrial oil and gas fields hosted in crystallized rocks, most occurred in granite rocks, occupying 40% in quantity and 75% in reserves, followed by those hosted in mafic and ultra-mafic rocks （about 3%）, and then tbllowed by those in volcanic rocks and metamorphic rocks.展开更多

Ltd. last year were 4 percent higher than those in 2012. but the company didn＇t make much money, accord- ing to Li Haifu. owner of the company. Sitting in the Dahongmen area. Haifu is mainly engaged in the production of curtains and beddings. with most of its products being exported. According to Li. for exported products, the U.S. dollar is used at all stages from ordering to settling, and it takes four months for the company to collect the payment for goods. Owing to fierce competition in the textile market, the prices charged cannot be too high.展开更多

The use of Heart rate variability (HRV) has become increasingly popular as a non-invasive methodology that provides an indirect insight into the autonomic nervous system. HRV can be utilized as a diagnostic tool in detection of autonomic nervous system impairment and sympatho-vagal imbalance. HRV technology is employed to monitor the internal response of athletes to workload and identify athletes’s psychophysical stress to predict and therefore prevent injuries. Objective: The objective of the investigation is to establish whether the use of Polar H10 sensor heart rate monitors worn by athletes in a sitting position (inclination 60 degrees) during periods characterized by stress can provide a valid and non-invasive method to assess the psychophysiological state during sports competition and school exams. Method and Statistics: In the study, the HRV of 12 basketball students athletes and 4 students non-athletes was analyzed as a control group. The autonomic nervous system activity was assessed based on heart variability parameters (HRV): SDNN, rMSSD, LF, HF, and LF/HF. The measurements were made after establishing the baseline at rest, during the training phase (CT), competition phase (CC) and during the acute phase of stressors due to school exams coinciding with the competitive season (CC + E). Results: Compared to the respective values prior to the stress of the competitions and exams, a significant decrease in HRV indices was found: SDNN (P Conclusions: The analysis and examination of the data on the sample of the student population also showed a statistically significant correlation between decreased cardiac variability and injuries or indisposition to physical exertion.展开更多

Sleep driving (SD) is often classified as a variant of somnambulism. Although, somnambulism has been reported as a side effect of varenicline, varenicline-induced sleep driving (VISD) has not been reported. Case Report: A 56-year-old man with a history of 35 pack year smoking who presented for smoking cessation counseling. Treatment with varenicline was initiated. In the following night, the patient drove to a shopping center and woke up in his car. Varenicline was discontinued. SD has not been reported in the following nights. In a repeated attempt to stop smoking, treatment with varenicline was resumed by the patient. SD reoccurred in the following night. Varenicline was discontinued indefinitely, and SD has not been reported.展开更多
