Temporal-spatial Changes in Inner Mongolian Grassland Degradation during Past Three Decades

[Objective] This study aimed to analyze the temporal-spatial variation of Inner Mongolian grassland degradation during past three decades. [Method] The dis- tribution characteristics of grassland were described by land use types supervised classification with TM/ETM. Then, temporal-spatial changes of grassland coverage were quantified by the mean of maximum vegetation coverage in last 30 years. Lastly, the grassland degradation reasons were explored through statistic analysis between the grassland coverage and precipitation, temperature and grazing intensity. [Result] The grassland degradation index of Inner Mongolia was increased from 1.38 to 1.68, and the smallest was 1.28 in 2005s. Grassland degradation and improve- ment were concurrent after 1980s, but grassland degradation was the major change trend for Inner Mongolia grassland. The area of grassland degradation was enlarged from 18.08×10^4 km2 in 1980s to 22.47×10^4 km2 in 2010s on the whole and distribu- tion range was shifted from central-eastern to west in Inner Mongolia that mainly distributed on Hulun Buir and Xilin Gol grassland in 1980s and Ordos and Alax grassland in 2010s. The grassland area of degradation had a rising trend form 1980s to 1995s, then reduced to 10.8x104 km2 in 2005s, and decreased in 2010s, which mainly speared in the west of Xilin Gol grassland. [Conclusion] Inner Mongo-lian grassland degradation were become more seriously in last 30 years because that temperature, precipitation and graze intensities change, which not performance on decreasing coverage but grassland areas.

Nutritional support teams increase percutaneous endoscopic gastrostomy uptake in motor neuron disease

AIM:To examine factors influencing percutaneous endoscopic gastrostomy(PEG) uptake and outcomes in motor neuron disease(MND) in a tertiary care centre.METHODS:Case notes from all patients with a confirmed diagnosis of MND who had attended the clinic at the Repatriation General Hospital between January 2007 and January 2011 and who had since died,were audited.Data were extracted for demographics(age and gender),disease characteristics(date of onset,bulbar or peripheral predominance,complications),date and nature of discussion of gastrostomy insertion,nutritional status [weight measurements,body mass index(BMI)],date of gastrostomy insertion and subsequent progress(duration of survival) and quality of life(QoL) [Amyotrophic Lateral Sclerosis Functional Rating Scale-Revised(ALSFRS-R)].In addition,the type of clinician initiating the discussion regarding gastrostomy was recorded as Nutritional Support Team(involved in providing nutrition input viz Gastroenterologist,Speech Pathologist,Dietitian) and other(involved in non-nutritional aspects of patient care).Factors affecting placement and outcomes including length of survival,change in weight and QoL were determined.RESULTS:Case records were available for all 86 patients(49 men,mean age at diagnosis 66.4 years).Thirty-eight patients had bulbar symptoms and 48 had peripheral disease as their presenting feature.Sixty-six patients reported dysphagia.Thirty-one patients had undergone gastrostomy insertion.The major indications for PEG placement were dysphagia and weight loss.Nine patients required immediate full feeding,whereas 17 patients initially used the gastrostomy to supplement oral intake,4 for medication administration and 1 for hydration.Initially the PEG regime met 73% ± 31% of the estimated total energy requirements,increasing to 87% ± 32% prior to death.There was stabilization of weight in patients undergoing gastrostomy [BMI at 3 mo(22.6 ± 2.2 kg/m 2) and 6 mo(22.5 ± 2.0 kg/m 2) after PEG placement compared to weight at the time of the procedure(22.5 ± 3.0 kg/m 2)].However,weight loss recurred in the terminal stages of the illness.There was a strong trend for longer survival from diagnosis among MND in PEG recipients with limb onset presentation compared to similar patients who did not undergo the procedure(P = 0.063).Initial discussions regarding PEG insertion occurred earlier after diagnosis when seen by nutrition support team(NST) clinicians compared to other clinicians.(5.4 ± 7.0 mo vs 11.9 ± 13.4 mo,P = 0.028).There was a significant increase in PEG uptake(56% vs 24%,P = 0.011) if PEG discussions were initiated by the NST staff compared to other clinicians.There was no change in the ALSFRS-R score in patients who underwent PEG(pre 34.1 ± 8.6 vs post 34.8 ± 7.4),although in non-PEG recipients there was a nonsignificant fall in this score(33.7 ± 7.9 vs 31.6 ± 8.8).Four patients died within one month of the procedure,4 developed bacterial site infection requiring antibiotics and 1 required endoscopic therapy for gastric bleeding.Less serious complications attributed to the procedure included persistent gastrostomy site discomfort,poor appetite,altered bowel function and bloating.CONCLUSION:Initial discussion with NST clinicians increases PEG uptake in MND.Gastrostomy stabilizes patient weight but weight loss recurs with advancing disease.

The Research of the Influential Factors of Wearing Comfort of Functional Underwear

Along with the rich material life, the change of the diet structure, people＇s shape also began to change.With performance m females is the body fat＇s increasing, the shape is not beautiful, therefore, body sculpting underwear has become the first choice for women to pursue beauty.To the requirement of sculpting body underwear is also becoming higher and higher for women.Comfortable and fashion is the sign of measuring a sculpting body underwear quality. This paper introduces the development history of sculpting body underwear, sculpting body underwear comfort evaluation index.And from the three aspects of the human body, clothing, environment do research to sculpting body underwear about the influence factors of wearing comfort.lt provides the certain reference value for consumers to purchase the sculpting body underwear and for enterprise to product sculpting body underwear.

A Probe on the Influential Factors in Content-Based ESP Courses Design

Recent years, problems of the current college English courses, such as test-oriented teaching, wasteful duplication of language skills teaching, etc., have been criticized by educators and students in China. Thus, turning skill-based English courses into content-based ESP （English for Special Purposes） courses has become a tendency at colleges and universities in China. The purpose of this paper is to analyze factors influencing the design of such courses through the means of questionnaire, individual interviews, data survey （e.g., educational plans） etc.. We found the following factors throw light on the questions relating to curriculum design of ESP courses： （1） the learners＇ learning needs; （2） the social needs （esp. labor market needs）; and （3） the academic needs from the university. The analysis serves to reveal the gap between the school system and actual social and students needs. With these factors in mind, designers of such courses can adjust goals, contents, approaches, and assessments in the practical teaching. And thus these factors would enable content-based ESP courses to reflect learners＇ needs better and lead to more effective langrage learning in college English teaching field.

Building towards a standardised approach to biocorrosion studies: a review of factors influencing Mg corrosion in vitro pertinent to in vivo corrosion

The factors that influence magnesium（Mg）corrosion in vitro are systematically evaluated from a review of the relevant literature. We analysed the influence of the following factors on Mg biocorrosion in vitro：（i） inorganic ions,including both anions and cations,（ii） organic components such as proteins, amino acids and vitamins, and（iii） experimental parameters such as temperature, p H, buffer system and flow rate. Considerations and recommendations towards a standardised approach to in vitro biocorrosion testing are given. Several potential simulated body fluids are recommended. Implementing a standardised approach to experimental parameters has the potential to significantly reduce variability between in vitro biocorrosion tests, and to help build towards a methodology that accurately and consistently mimics in vivo corrosion. However, there are also knowledge gaps with regard to how best to characterise the in vivo environment and corrosion mechanism. The assumption that blood plasma is the correct bodily fluid upon which to base in vitro methodologies is examined, and factors that influence the corrosion mechanism in vivo, such as specimen encapsulation, bear consideration for further studies.
