lithiumization of the vacuum vessel wall of the Aditya tokamak using a lithium rod exposed to glow discharge cleaning plasma has been done to understand its effect on plasma performance. After the li-coating, an increment of ~100 eV in plasma electron temperature has been observed in most of the discharges compared to discharges without li coating, and the shot reproducibility is considerably improved. Detailed studies of impurity behaviour and hydrogen recycling are made in the li coated discharges by observing spectral lines of hydrogen, carbon, and oxygen in the visible region using optical fiber, an interference filter, and PMT based systems. A large reduction in O I signal （up to ~40% to 50%） and a 20% to 30% decrease of Ha signal indicate significant reduction of wall recycling. Furthermore, VUV emissions from O V and Fe XV monitored by a grazing incidence monochromator also show the reduction. lower Fe XV emission indicates the declined impurity penetration to the core plasma in the li coated discharges. Significant increase of the particle and energy confinement times and the reduction of Zeff of the plasma certainly indicate the improved plasma parameters in the Aditya tokamak after lithium wall conditioning.

上气道梗阻(UAO)是儿童气管插管拔管失败常见原因之一。糖皮质激素(GC)能减轻气道损伤所致的炎性水肿,可能有助于预防拔管后UAO,但其疗效仍存在争议。虽然有相关指南、共识建议存在拔管失败风险的高危患儿预防性应用全身性GC,但国内外尚无统一的用药方案。本文就全身性GC预防儿童气管插管拔管后UAO的临床研究进行综述,以期为临床治疗提供参考。

Background: Work related low back pain has been identified as a one of the most costly disorders among the worldwide working population. This condition was highly prevalent that approximately 85% patients having back pain were brought on by prolonged sitting. With the rapid development of modern technology, sitting has now become the most common posture in today’s work- place. Idea of using motor control learning approach provides the optimal control and coordination of the spine. The McKenzie evaluation was received using repeated movements and sustained positions. Therefore high quality randomized clinical trial was required to compare the effectiveness of these treatments for work related low back pain. Objectives: To compare the effectiveness of motor control exercises and McKenzie exercises in reducing pain and disability in work related low back pain. Method: The study included 40 subjects with work related low back pain due to prolonged sitting. They were randomly allocated into two groups (Group A and Group B). Group A was treated with motor control exercises and group B was treated with McKenzie exercises for 4 weeks. results: Both the groups have shown statically significant improvement in vas with p rison was done after the 4 weeks, the percentage of improvement in group A was much higher than Group B. Conclusion: The study concluded that motor control exercises have shown statically and clinically significant improvement in reducing pain and disability when compared to McKenzie exercises among work related low back pain subjects.

Introduction: The primary objective of this study was to determine whether risedronate sodium (Actonel?) therapy, in conjunction with conventional non-surgical periodontal treatment, reduces the rate of alveolar bone loss. Secondary aims were to compare the incidence of patient dropouts in the risedronate and placebo groups, and to document adverse events. Methods: This double-blind randomized placebo-controlled trial was conducted in 125 patients with moderate to severe periodontitis. At baseline, three, and nine months, standardized vertical bite-wing radiographs were taken and used to measure bone loss. Clinical periodontal examinations were taken at three-month intervals to assess whether or not the patient was experiencing rapid periodontal breakdown, in which case suitable treatment could be planned and delivered. Patients received scaling and root planing at baseline and periodontal maintenance at three-month intervals thereafter. At three months, subjects were randomly assigned to risedronate (35 mg/week by mouth) or placebo in blocks based on the severity of periodontitis (moderate, mean bone loss 2 -4 mm;or severe, mean bone loss >4 mm);smoking;and diabetes. Interval bone loss in millimeters was measured from the radiographs, and analysis of variance (ANOVA) was used to test for differences in bone loss between test and placebo groups. results: Over the nine-month study duration, the test group exhibited a significantly greater increase in bone height (0.31 ±0.09 mmgain test, 0.08 ±0.09 mmgain placebo, F = 4.94, p re were significantly fewer dropouts in the risedronate treated group (4.8%) than in the placebo treated group (17.5%;p r Exact Test). No serious adverse events or cases of osteonecrosis of the jaw (ONJ) were observed. Conclusions: Periodontitis subjects treated with risedronate had significantly more bone gain compared to placebo treated subjects. Significantly more subjects from the placebo group dropped out, suggesting

蒙古高原东部草原火频繁发生,波及面广,对畜牧业发展威胁很大。本研究以蒙古高原草原火高频区2001-2020年的MCD64A1遥感火烧迹地数据为基础,利用时空立方体模型挖掘草原火的时空演变模式。结果表明:整体上,草原火从西南向东北逐渐增多,以国境线为界的火发生面积差异明显,主要分布在蒙古国境内,并存在明显的年际变化,每隔3~4年出现一次草原火发生的高峰。草原火高频集聚立方体的空间和时间自相关关系比较复杂,火事件的规律性差,不具有连续性,对防火防灾带来困难。草原火发生频率显著高或低的个别点主要分布在人口聚集的镇所在地;呼伦贝尔市东部、西部国境线附近,肯特省北部,东方省西南角、东北部、东南部以及与新巴尔虎左旗交界处草原火虽不连续发生,但近期发生频率较高,需要高度警惕。利用时空立方体挖掘蒙古高原草原火高频区时空演变模式,可为准确、快速识别草原火多发点位及其时空演变特性,网格化管理草原火,管护员巡查调度、草原火预测、降低火灾发生频率等提供辅助决策。
