A high resolution nonhydrostatic tropical atmospheric model is developed by using a ready-made regional atmospheric modeling system. The motivation is to investigate the convective activities associated with the tropical intraseasonal oscillation (IsO) through a cloud resolving calculation. Due to limitations in computing resources, a

We collected soil samples from two representative sites at Aatmile of Khagarachari hill district in Chittagong Hill Tracts. One of the sites was under shifting cultivation and the other an adjacent 13-year old teak plantation. Both sites were in the same physiographic condition and same aspect with parable soil type, which enabled us to measure the effects of shifting cultivation on soil micro-flora. We studied soil phys-ico-chemical properties and the biochemical and biological properties of soil microbes. Moisture and organic matter content as well as fungi and bacterial populations, both in surface and subsurface soils, were signifi-cantly （p≤0.001） lower in shifting cultivated soils compared to soils not under shifting cultivation, i.e. the teak plantation site. The most abundant bacteria in surface （0-10 cm） and sub-surface （10-20 cm） soils under shifting cultivation were Pseudomonas diminuta and shigella, respec-tively, while in corresponding soil layers of teak plantation, predominant microbes were Bacillus firmus （0-10 cm） and Xanthomonas （10-20 cm）. The microbial population differences cannot be explained by soil texture differences because of the textural similarity in soils from the two sites but could be related to the significantly lower moisture and organic mat-ter contents in soils under shifting cultivation.

Gas tungsten arc (GTA) welding was performed both in a microgravity environment and in a terrestrial environment,and the arc shapes in both environments were compared. A microgravity condition was obtained using the free fallsystem at the Japan Microgravity Center. The system can maintain a 10 s microgravity of less than 10-5 g. Awater-cooled Cu plate was used to simplify the arc phenomenon. The electric arc current was between 15 and 80 A,and the shielding and atmospheric gas was 99.9995% Ar and its flowing rate was 10 l/min. The polarity was a directcurrent electrode negative (DCEN). The arc gap was 3 mm and careful attention was also paid to the arc gap in boththe terrestrial and microgravity environments being the same. As a result, it was found that no effect of gravity onthe arc shape is observed under general welding conditions (over 60 A). When the electric arc current is lower than25 A, the arc shape is determined by the initial position of the arc root and is constant with time. Accordingly, itcan not be judged whether or not the arc shape is affected by gravity for this range. When the electric arc current isbetween 25 A and 60 A, it is estimated that the arc shape is not affected by gravity though it is occasionally affectedby other minor effects.

The purpose of this experimental study was to evaluate and record the effects of T-2 toxicity alone and in association with IBV infection on haematobiochemical parameters. A total of 128 one-week-old chicks were divided into four groups of 32 birds each and were treated respectively with T-2 toxin alone, IBV alone, T-2 toxin and co-infected with IBV, and no treatment (control) for a period of 6 weeks. Haematologically, the birds treated with T-2 toxin developed anaemia as indicated by significant decrease in haemoglobin levels, total erythrocyte counts and packed cell volume values;leucopenia, lymphocytopenia heterophilia and thrombocytopenia. The IBV infected birds exhibited lymphocytophilia and heteropoenia;the degrees of severity of leucopenia, lymphocytopenia heterophilia and thrombocytopenia were more pronounced in T-2+IBV groups. The serum biochemistry revealed hypoproteinemia and hypoalbuminemia in all the treated groups consistently. Besides, hypoglobulinemia and increased levels of alanine aminotransferase in T-2+IBV, and increased levels of alkaline phosphatase in toxin group alone were recorded. The changes in biochemical parameters were more in magnitude in the combination treatment group and their severity increased with duration of treatment. It was concluded that T-2 toxin made the birds more susceptible to IBV infection.

The objective of this study was to determine if sleep indicators are associated with subjective fatigue in nurses working in a rotating, two-shift system with a 16-hour night shift, using the wearable device Fitbit One. subjective fatigue was evaluated using the subjective Fatigue symptom Questionnaire (sFsQ), a rating scale developed by the Working Group for Occupational Fatigue of the Japan society for Occupational Health. subjects were asked to continuously wear a Fitbit One to obtain the following data: time in bed (TIB), deep sleep time, length and frequency of nighttime awakening, sleep efficiency, waking time, and bed time. Nurses had a mean age and standard deviation of 33.2 ± 7.5 years and had worked as nurses for 9.8 ± 6.2 years on average. Eight nurses were in their 20s (42.1%), 5 in their 30s (26.3%), and 6 in their 40s (31.6%). All participants were female. Participants’ sFsQ scores calculated from the 9 evenings in the study period were averaged to establish a threshold for categorizing high-fatigue (HF) and low-fatigue (LF) groups. No significant differences were found between HF and LF nurses in terms of TIB, deep sleep time, nighttime awakening time or frequency, or sleep efficiency on any type of day (as classified by shift, day off, etc.). Nurses in both groups woke up significantly later on days off and on pre-night-shift days than on day-shift days. These results demonstrate the variation in sleep patterns of nurses on a rotating, two-shift system between day-shift and night-shift days.

Islet transplantation could become an ideal treatment for severe diabetes to prevent hypoglycemia shock and irreversible diabetic complications, once some of the major and unresolved obstacles are overcome, including limited donor supplies and side effects caused by permanent immunosuppressant use. Approximately 30 years ago, some groups succeeded in improving the blood glucose of diabetic animals by transplanting encapsulated islets with semi-permeable membranes consisting of polymer. A semi-permeable membrane protects both the inner islets from mechanical stress and the recipient’s immune system (both cellular and humoral immunities), while allowing bidirectional diffusion of nutrients, oxygen, glucose, hormones and wastes, i.e., immune-isolation. This device, which enables immune-isolation, is called encapsulated islets or bio-artificial pancreas. Encapsulation with a semipermeable membrane can provide some advantages: (1) this device protects transplanted cells from the recipient’s immunity even if the xenogeneic islets (from large animals such as pig) or insulin-producing cells are derived from cells that have the potential for differentiation (some kinds of stem cells). In other words, the encapsulation technique can resolve the problem of limited donor supplies; and (2) encapsulation can reduce or prevent chronic administration of immunosuppressants and, therefore, important side effects otherwise induced by immunosuppressants. And now, many novel encapsulated islet systems have been developed and are being prepared for testing in a clinical setting.

INTRODUCTION The United Nations(UN)Decade of Healthy Ageing(2021–2030),coordinated by the World Health Organization(WHO),1 is a global collaborative initiative aimed at improving the lives of older people,their families and the communities.23 The Action Areas 3(ie,‘deliver person-centred,integrated care and primary health services responsive to older people’)and 4(ie,‘provide access to long-term care(LTC)for older people who need it’)of the Decade’s work programme focus on reorienting health and care systems to promote‘ageing in place’and the delivery of personalised interventions in a seamless continuum of care.
