The study was conducted to assess the livelihood of fishermen in Monirampur Upazila of Jessore district from July to December, 2012. The mean age and fishing experience of fishermen were 35.22±9.67 and 17.9±7.12 years, respectively. Primary occupation for majority fishermen (90%) was fishing. The mean monthly income of the household (HH) was BDT 9470±4806.89. Only 2% fishermen were landless. 4% fishermen had training on fishing/fish culture. 46% fishermen involved in NGOs for loan and savings. 52% fishermen cultivated paddy during boro (summer) season whereas only 18% cultivated paddy during aman (rainy) season. Major protein sources to the HHs (monthly) were- small indigenous species (SIS) (4.60±2.64 kg), non-SIS (6.31±4.18 kg), meat (3.54±1.67 kg), eggs (18.73±22.20 pieces), and milk (11.10±15.54 liter). The major HH expenditures were- food, education, health, furniture, cloths and others. All fishermen were vulnerable to vabadaha, a situation when water logging takes place during monsoon due to lack of sufficient water drainage system.

Sample Method

Radium-bearing barytes (radiobarytes) have been known since the beginning of the 20th century. They are mainly found as precipitates of low-temperature hydrothermal solutions. In anthropogenic environments, they frequently occur as crusts on oil industry equipment used for borehole extraction, in leachates from uranium mill tailings, and as a by-product of phosphoric acid manufacturing. Recently, we recognized Ra-rich baryte as a precipitate in the water drainage system of a bituminous coal mine in the Czech part of the Upper Silesian Basin. The precipitate is a relatively pure baryte, with the empirical formula (Ba0.934Sr0.058Ca0.051Mg0.003)Σ1.046S0.985O4.000. The mean specific activity of 226Ra was investigated by the two-sample method and it equals 39.62(22) Bq/g, a level that exceeds known natural occurrences. The values for 228Ra and 224Ra are 23.39(26) Bq/g and 11.03(25) Bq/g. The radium content in the baryte is 1.071 ng/g. It is clear that the Ra-rich baryte results from the mixing of two different mine waters—brines rich in Ba, Sr, and isotopes 226Ra and 228Ra and waters that are affected by sulfide weathering in mine works. When this mixing occurs in surface watercourses, it could present a serious problem due to the half-life of 226Ra, which is 1600 years. If such mixing spontaneously happens in a mine, then the environmental risks will be much lower and will be, to a great, extent eliminated after the closure of the mine.

Abstract Background: Adequate and healthy diet during pregnancy is essential for the health of both mother and newborn. Dietary diversity is a proxy indicator of maternal nutrient adequacy. However, little is documented on the prevalence of dietary diversity among pregnant women. This study was aimed to assess the dietary diversity practice and associated factors among pregnant women attending antenatal care in health centers of the coffee keranyo sub city, Addis Ababa, Ethiopia. Methods: Institution based cross-sectional study was conducted on 406 randomly selected pregnant women attending ANC in health centers of the coffee keranyo sub city, Addis Ababa from March 2-April 2/ 2018. Data were collected by using interviewer and 24 H dietary recall method. Data had entered and analyzed using SPSS version 21. Multiple logistic regression was run to assess factors associated with the dependent variable at P<0.05. Results: The mean Dietary Diversity Score of pregnant women was 5. 45+-1. 83. About 60.9% of pregnant women had good dietary diversity practice. Pregnant women who learned collage and above had more dietary diversity practice than the illiterate one [AOR=2.26, 95% CI: (1.066, 4.808)]. Pregnant women with monthly income more than 5,000 ETB had more dietary diversity than income less than 2,000 ETB [AOR=2.33, 95% CI: (1.234, 4.416)]. Pregnant women at second antenatal care visit had more dietary diversity than at the first visit [AOR=2.42, 95% CI: (1.183, 4.952)]. Having nutrition information during pregnancy increases 2 times better dietary diversity practice than none informed ones [AOR=2.10, 95% CI: (1.294, 3.422)].Conclusions: The mean Dietary Diversity Score of pregnant mothers was 5.45. And 60.9% of pregnant women had a good dietary diversity score, whereas 39.1 % of them had a poor diet diversity score. Mothers’ education, monthly income, second and third antenatal care visit and nutrition information had a significantly associated with pregnant mothers’ dietary diversity.

INTRODUCTION This is a prospective study looking at the effectiveness of autologous postoperative drains in primary uncemented total hip replacement (THR) surgery. PATIENTS AND METHODS A total of 86 patients were studied, with 43 using standard suction drains (normal drain group) and 43 using autologous drains (autologous drain group). RESULTS Thirty-seven units of homologous blood were transfused in the normal drain group and 5 units in the autologous drain group. The mean number of units of homologous blood transfused per patient was reduced from 0.86 to 0.12 (P < 0.01) with the use of autologous drains and the transfusion rate was reduced from 23% to 6% (P < 0.02). The mean length of hospital stay was also reduced by two nights (P < 0.05). There were no adverse effects from using the autologous system and it does reduce the need for a homologous blood transfusion. CONCLUSIONS The system is simple and easy to use and we have also found it to be cost effective. Previously, it has not been reported as being effective in hip arthroplasty surgery, unlike knee arthroplasty surgery. We would recommend using autologous postoperative drains in primary THR surgery.

In the paper were made the verification of the operation of a rainwater drainage system in the residential communities of Gaj and Tarnogaj in Wrocław, carried out in the hydrodynamic model using SWMM software. There were used two criterial precipitation: Euler’s model (with a frequency of C = 3 years) and the actual precipitation (C = 5 years). The criteria of overloading the system was the specific flood volume (SFV). For both cases of precipitation load of catchment, the simulated calculations showed the occurrence of outflows from the channels. Due to the value of SFV indicator (respectively: 19 m3/ha and 42,9 m3/ha), it was found that the tested system needs modernization, therefor acceptable instantaneous water level above the maximum water impoundment were more often than 1 per 3 years, which leads to overflows from channels for residential areas more often than allowed once every 20 years.

Abstract Objectives Pruritus is the most common reason for dog visits to veterinarians for dermatological diagnosis. Here we hypothesize that dietary intervention alleviates pruritus by reducing intestinal inflammation to improve skin health. Methods Control food (CF) and Test food (TF) were formulated to meet or exceed AAFCO nutritional recommendations. Difference between the foods was inclusion of grains in TF. Both foods had similar macronutrient levels (fat: 15.33% ± 1.73, protein: 16.57% ± 0.35, carbohydrate: 53.16% ± 1.15, crude fiber: 2.1% ± 0.1, total dietary fiber: 9.5% ± 0.3, moisture: 7.35% ± 0.08 and ash: 5.49% ± 0.05). A feeding study was performed with 15 derm disorder dogs (DD) and pair-matched 15 healthy dogs (HD). All dogs were pre-fed with maintenance food for 28 days and then randomized into 2 groups based on their age, gender and disease condition. A feeding study was performed using a cross-over design without a washout period and each phase was fed for 42 days. Fecal and blood samples were collected and assessment of skin symptoms was conducted by a veterinarian for all dogs at all phases of the study. Results DD increased the response rate 14.29% for pruritus reduction when fed TF compared with CF. Also, DD fed with TF decreased the mean level of fecal calprotectin (FC) (57.914 ng/g SE ± 52.26) compared with CF (129.09 ng/g SE ± 54.10). However, HD fed with TF showed no decrease in the mean level of FC (36.40 ng/g SE ± 6.49) compared with CF (33.68 ng/g SE ± 6.49). Number of DD that responded by decreasing FC levels increased to 42.86% fed with TF compared with CF. FC is a major protein released from neutrophils during the period of active inflammatory status and DD fed with TF increased the mean level of neutrophils count (4.28 k/µl SE ± 0.34) compared with CF (3.85 k/µl SE ± 0.34). However, HD fed with TF did not show any increase in the mean level of neutrophils count (3.97 k/µl SE ± 0.21) compared with CF (3.77 k/µl SE ± 0.22). Our results suggest that a decrease in FC levels with TF, likely indicating a reduction in the inflammatory status in the gut, was due to the addition of grains in TF. Conclusions TF intervention alleviates pruritus by reducing intestinal inflammation to improve skin health in dogs. Funding Sources This study was funded by Hill's Pet Nutrition, Inc.

Englacial Drainage

AbstractRecent speleological surveys of meltwater drainage systems in cold and polythermal glaciers have documented dynamic englacial and in some cases subglacial conduits formed by the ‘cut-and-closure’ mechanism. Investigations of the spatial distribution of such conduits often require a combination of different methods. Here, we studied the englacial drainage system in the cold glacier Longyearbreen, Svalbard by combining speleological exploration of a 478 m long meltwater conduit with a high-resolution ground penetrating radar (GPR) survey with two different centre-frequencies (25 and 100 MHz). The results yielded a 3-D documentation of the present englacial drainage system. The study shows that the overall form of englacial conduits can be detected from velocity−depth converted GPR data, and that the 3-D model can facilitate a method to pinpoint the reflections in a radargram corresponding with the englacial drainage system, although fine detail cannot be resolved. Visible reflections approximately parallel to the mapped englacial water drainage system likely result from sediment incorporated in the ice or from abandoned parts of the englacial drainage system.

Horizontal Grid

&lt;p&gt;Several current general atmospheric circulation models provide sufficiently high resolutions to resolve important parts of the internal gravity wave spectrum allowing for numerical experiments without GW drag parameterizations. GWs start to be well resolved from horizontal wavelengths of about 7 times the horizontal grid spacing. How much does the resolved wave spectrum and its forcing on the mean circulation depend on the vertical resolution?&lt;/p&gt;&lt;p&gt;&amp;#8722;1,The middle atmosphere summer hemisphere provides a suitable background to investigate this question. The mean stratospheric and mesospheric circulation is characterised by prevailing easterlies which prevent planetary wave propagation upwards and represents a mean state driven by IGWs. The sensitivity of the forcing by IGWs is analysed on the basis of the Eliassen-Palm (EP) flux divergence, which describes the forcing on the circulation by resolved eddies.&lt;br&gt;Model simulations are performed using the upper atmosphere version of the ICON (ICOsahedral Nonhydrostatic) general circulation model, UA-ICON (Borchert et al. 2019, GMD). The simulations start in October and run for an extended austral summer season until March with a horizontal grid spacing of roughly 20 km. The top of the model atmosphere is located at 150 km. Three different model configurations are used with 90, 180, and 360 vertical model layers. The mean vertical grid spacing ranges from roughly 1300 m (90 layers) to 320 m (360 layers) at stratospheric levels, and from roughly 2300 m to 500 m at mesospheric levels. Gravity wave drag parameterizations (orographic and non-orographic) are turned off. The resolved forcing on the mean state due to the EP flux divergence is decomposed into contributions of different scales with respect to horizontal wave numbers. For contributions of IGWs wave numbers above 20 are considered.&lt;/p&gt;&lt;p&gt;The stratospheric and mesospheric easterlies appear stronger in the lower resolution from October to the end of the austral summer season. Westerlies occur above the mesopause. This strong vertical gradient in the zonal mean zonal wind amplifies in the lower resolution. At the beginning of the simulation period, differences between the mean states are weak, of the order of 5 ms&lt;sup&gt;&amp;#8722;1&lt;/sup&gt; , and strengthen during the summer season. The forcing due to internal GWs appears stronger in the lower resolution at higher altitudes and amplifies in the region of the strong vertical gradient of the zonal mean zonal wind. Furthermore, wave spectra are discussed. In accordance with previous studies, an increased vertical resolution results in a reduction of the IGW forcing close to strong zonal mean zonal wind gradients in the upper mesosphere/lower thermosphere.&lt;/p&gt;
