Displacement of soil particles by erosion can be seen as a major threat to the quality of agricultural land in the conditions of Czech Republic. While the effects of water and wind erosion have long been investigated and reported, the effect of soil tillage technology on soil particles translocation are relatively new area of agriculture research. Soil tillage may contribute to the undesirable translocation of soil particles towards lower-lying parts of fields especially on slopes. The effect of soil tillage implements on soil particle translocation has not been sufficiently explained yet. The object of this research was to assess the influence of different operating speed of power harrow on soil particle translocation during secondary tillage (soil preparation). Measurements to determine the displacement of soil particles were performed in location Nesperská Lhota in the Central Bohemia Region. Measurements were performed on a sandy loam cambisol after harvest spring cereals (oat for sillage production). To indicate displacement of soil particles was used grit of white limestone (size 10-16 mm). Limestone was put down into the trench with known position orthogonal to the direction of working operations. Subsequently were performed working operations in the specified sequence. Limestone particles were counted and weighed in each section. It was detected by measuring the different nature of displacement. Statistical significance of differences in the weight of translocated particles was evaluated for different operating speeds of power harrow from 4.5 to 12 km.h-1.

Mount Merapi eruption in 2010 that discharged more than 130 million m3 of landfill material brought impact on the thickness and height of caused damage to the yard and agricultural land. After mining heap of materials in the form of boulders, stones, gravels, and gravel to sand, RLKT activities (Rehabilitation and Soil Conservation) needs to be pursued to mobilize the people in the village of Kepuharjo. Cooperation between BPTKPDAS Solo with Kepuharjo Village community is incorporated in FPL PALEM (Environmental Care Forum Merapi Slope-Nature Lovers) by performing RLKT barrier in the form of grass planting (Grass Barriers) and manure treatment with the observation of surface erosion due to the effects of wind on the rorak. The purpose of this study was to quantify the effectiveness of grass barrier for wind erosion control at the land formerly affected by eruption at Merapi Mountain. The results show that the combination of grass and manure was able to suppress the erosion up to 88%. Effective rorak types were derived from bucket and it is not recommended that rorak includes a stick for a heap of unstable soil particles. Therefore, the usage of plastic is not suggested as it is easily torn. ABSTRAKBencana erupsi Gunung Merapi tahun 2010 telah mengeluarkan material lebih dari 130 juta m3 dan berdampak pada penimbunan material yang tebal dan tinggi, sehingga menyebabkan kerusakan lahan pekarangan dan pertanian. Setelah dilakukan penambangan, timbunan material berupa batu besar, batu, kerakal, kerikil sampai pasir, maka perlu diupayakan kegiatan RLKT (Rehabilitasi Lahan dan Konservasi Tanah) dengan menggerakkan masyarakat di Desa Kepuharjo. BPPTPDAS Solo telah bekerjasama dengan masyarakat Desa Kepuharjo yang tergabung dalam FPL PALEM (Forum Peduli Lingkungan-Pecinta Alam Lereng Merapi) dengan melakukan RLKT berupa rumput penghalang (Grass Barriers) dan perlakuan pupuk kandang dengan pengamatan erosi permukaan akibat pengaruh angin pada rorak. Tujuan penelitian ini adalah untuk menghitung tingkat efektivitas rumput penghalang terhadap pengendalian erosi angin pada lahan bekas erupsi di Merapi. Hasil yang diperoleh bahwa rumput dan kombinasi dengan pupuk kandang mampu menekan erosi sampai 88%. Jenis rorak yang efektif adalah rorak yang berasal dari ember. Tidak disarankan menggunakan rorak dengan stik di dalamnya karena timbunan partikel tanah disekitar rorak yang tidak stabil, ataupun dengan plastik karena akan mudah robek.

A field study was conducted for soil which was irrigated by partially treated and untreated sewage in the Surroundings of Taiz City. The study aims at evaluating the level of degradation on agricultural soil in the study area as a result of the wastewater application. Four samples of soils have been collected from four different sites within the areas of Al-Qurf, Al-Hawajalah, Al-Buraihy and Hidran Al-Dabab, in addition to a control sample of soil from agricultural land irrigated only from seasonal rainwater at Mafraq Sharab. The results of mechanical analysis of the soil showed that the soil texture at the four different sites varied from one location to another. For instance, at Al-Qurf and al-Hawjalah areas, the soil texture was found to be Silt-Loam, whereas at Al-Buraihy and Hidran Al Dabab, the soil texture was clay, while the soil texture in Mafraq Sharab was loam. The results of the chemical analysis of the soil samples indicate that the soil irrigated from partially treated and untreated wastewater compared to the irrigated soil of rainwater was most affected by the high level of salinity and the calcium carbonate ratio. In addition, the chemical and heavy metals elements contents of the soil are high which is probably accumulated in soil over several years. This suggests an action of rapid treatment of land where salinity has accumulated significantly through soil rehabilitation, including soil tillage mixed with limited quantities of gypsum and soil leach with fresh, low-salty water, and thus soil cultivation with barley or sorghum yield and rotation of freshwater and treated wastewater irrigation.

The soil preparation for citrus seedlings planting can affect the longevity, yield, plant health and the quality of the mechanized operations, which must be performed to ensure the future crop management. In this context, this study aimed to evaluate the quality indexes of soil tillage systems during citrus transplanting, through the performance of the operation and the study of times and movements of the mechanized sets. The experiment was conducted in the municipality of Matão - São Paulo, Brazil, in a completely randomized design, with two systems for mechanized soil preparation (conventional and conjugate) to transplant the citrus, with 66 replicates for each treatment. Were evaluated as indicators of quality the wheels slip of the tractor, speed of the mechanized sets, the accuracy of the GPS receiver and a study of time and motion operations, to perform the calculation of the efficiency of the tillage operations of tillage was carried out. All quality indexes for the mechanized sets were unstable, which negatively affects the operations quality. The conjugated tilled system and the liming presented the lowest and the highest speed of the tractor-equipment when compared to others, respectively.

Background: Dementia after stroke, particularly subacute period is often overlooked. Today the quality of human life is increasingly high, finding scales that have high value for detection of dementia in patients with stroke is increasingly interested. MoCA test is high sensitivity with mild dementia and identify more abnormalities of awareness caused by vascular, but MoCA have not been studied much in Vietnam. Objective: Assessing MoCA test in subacute stroke patients and compare MoCA versus MMSE in these patients. Subjects: 90 patients with subacute stroke period, these people are being treated at Department of cardiovascular internal medicine at Hue Central Hospital, from 7/2014 - 7/2015. Methods: cross-sectional description and analysis. Results: The mean age is 65.57 ± 13.38, accounting for 54.4% male and 45.6% female. Age, duration of illness has weak correlation with MoCA. The risk factors: hypertension, stroke ischemic transient, alcoholism, smoking, heart disease, diabetes, dyslipidemia related no statistical significance with MoCA. The proportion of dementia in subacute stroke according MoCA is 82.2%. The concordance between MoCA and MMSE was good (kappa = 0.684). Using DSM-IV criteria as the gold standard we found MoCA more valuable in the dementia diagnosis than MMSE (AUC 0.864 versus 0.774, p <0.05). Conclusion: The rate of dementia in stroke subacute period according MoCA is quite high. MoCA is valuable than MMSE in detecting dementia in patients with stroke subacute period, this scale is short, easy to implement so should put into using widely in clinical practice. Key words: MoCA test, subacute stroke, dementia

Objective: To predict the quality of anticoagulation control in patients with atrial fibrillation (AF) receiving warfarin in Thailand. Materials and Methods: The present study retrospectively recruited Thai AF patients receiving warfarin for three months or longer between June 2012 and December 2017 in Central Chest Institute of Thailand. The patients were classified into those with SAMe-TT₂R₂ of 2 or less, and 3 or more. The Chi-square test or Fisher’s exact test was used to compare the proportion of the patients with poor time in therapeutic range (TTR) between the two groups of SAMe-TT₂R₂ score. The discrimination performance of SAMe-TT₂R₂ score was demonstrated with c-statistics. Results: Ninety AF patients were enrolled. An average age was 69.89±10.04 years. Most patients were persistent AF. An average CHA₂DS₂-VASc, SAMe-TT₂R₂, and HAS-BLED score were 3.68±1.51, 3.26±0.88, and 1.98±0.85, respectively. The present study showed the increased proportion of AF patients with poor TTR with higher SAMe-TT₂R₂ score. The AF patients with SAMe-TT₂R₂ score of 3 or more had a larger proportion of patients with poor TTR than those with SAMe-TT₂R₂ score of 2 or less with statistical significance when TTR was below 70% (p=0.03) and 65% (p=0.04), respectively. The discrimination performance of SAMe-TT₂R₂ score was demonstrated with c-statistics of 0.60, 0.59, and 0.55 when TTR was below 70%, 65% and 60%, respectively. Conclusion: Thai AF patients receiving warfarin had a larger proportion of patients with poor TTR when the SAMe-TT₂R₂ score was higher. The score of 3 or more could predict poor quality of anticoagulation control in those patients.

Banyuwangi Regency is one of the agricultural centers in East Java province and Indonesia. Mostly,Banyuwangi people work as farmers due to the fertil soil and wide amount of agricultural land in Banyuwangi . Thelarge number of people who work as farmers initiating the formation of farmer groups. One of the farmer groups in theSrono sub-district of Banyuwangi is the "Tan Selo 1" farmers group located in the village of Sukomaju and the "TanSelo 2" farmers group in Sukonatar village. The normal average price of one banana bunch in Banyuwangi is between50-60 thousand depending on the type and quality of bananas. Problems arise when the quantity of bananas in the marketarose, the price of 1 bunch of bananas decreases dramatically. The price of 1 bunch which is usually set at 50-60thousand drops drastically to only 20-30 thousand. This is certainly a problem for farmers in the Tan Selo group. The lackof knowledge of Tan Selo farmers about alternative variants of processed banana based products and the lack ofknowledge of the marketing strategies make it hard for the Tan Selo farmers to increase the economic value of bananaswhich have been used as an alternative income for farmers. Therefore, the solutions offered to overcome the problems offarmers include: equipping and improving farmers' knowledge about the variety of processed banana-based foods andtheir marketing strategies, conducting training to make variations on banana-based foods, conducting training oneffective marketing strategies. Overall, a series of community service programs were carried out perfectly as it expected.The percentage of participants' understanding in choosing high quality bananas is 85%, the percentage of participants’ability in processing banana-based foods is 86%, and percentage of participants who successfully sell processed foodproducts by utilizing online shopping sites is 70%

Abstract The assessment of the six-week influence of Kinesio Taping combined with a rehabilitation on selected ultrasonography measurements, the level of disability, and the quality of life in patients with rotator cuff lesions. 60 participants were randomly assigned into a taping group (KT combined with a six-week rehabilitating protocol) and a control group (only rehabilitation protocol). In all patients the following assessments were performed twice: USG, UEFI and NHP questionnaires. In the examination of the subacromial space and the subacromial bursa in the taping group, no statistical significance was observed. A statistically significant change in the thickness of the muscles was obtained only for the thickness of the infraspinatus in the taping group. A statistically significant change was obtained in the assessment of tendinopathy only for the supraspinatus muscle in both groups. Within both groups a statistically significant difference was observed in the average UEFI and NHP scores; however, the differences in the scores obtained between the groups were not statistically significant. The use of KT with a rehabilitation program did not yield statistically significantly better results in the improvement of selected shoulder region indicators, the function of the upper limb and the quality of life.

Negative Effect

Cryopreserved haematopoietic progenitor cells are used to restore autologous haematopoiesis after high dose chemotherapy. Although the cells are routinely stored for a long period, concerns remain about the maximum storage time and the possible negative effect of storage on their potency. We evaluated the effect of cryopreservation on the quality of peripheral stem cell grafts stored for a short (3 months) and a long (10 years) period and we compared it to native products.The viability of CD34+ cells remained unaffected during storage, the apoptotic cells were represented up to 10% and did not differ between groups. The clonogenic activity measured by ATP production has decreased with the length of storage (ATP/cell 1.28 nM in native vs. 0.63 in long term stored products, P < 0.05). Only borderline changes without statistical significance were detected when examining mitochondrial and aldehyde dehydrogenase metabolic activity and intracellular pH, showing their good preservation during cell storage. Our experience demonstrates that cryostorage has no major negative effect on stem cell quality and potency, and therefore autologous stem cells can be stored safely for an extended period of at least 10 years. On the other hand, long term storage for 10 years and longer may lead to mild reduction of clonogenic capacity. When a sufficient dose of stem cells is infused, these changes will not have a clinical impact. However, in products stored beyond 10 years, especially when a low number of CD34+ cells is available, the quality of stem cell graft should be verified before infusion using the appropriate potency assays.

Abstract Background and study aims Bowel preparation for colonoscopy is frequently inadequate in hospitalized patients. We explored the impact of specific verbal instructions on the quality of inpatients bowel preparation and factors associated with preparation failure. Patients and methods Randomized (1:1), two strata (mobilized vs. bedridden; 3:2) trial of consecutive inpatients from four tertiary centers, who received either specific, verbal instructions or the standard of care (SOC) ward instructions about bowel preparation. The rate of adequate bowel preparation (Boston Bowel Preparation Score [BBPS] ≥ 6, no segment < 2) comprised the primary endpoint. Mean BBPS score, good (BBPS score ≥ 7, no segment score < 2) and excellent (BBPS = 9) were among secondary endpoints. Results We randomized 300 inpatients (180 mobile) aged 71.7 ± 15.1 years in the intervention (49.7 %) and SOC (50.3 %) groups, respectively. Overall, more patients in the intervention group achieved adequate bowel preparation, but this difference did not reach statistical significance neither in the intention-to-treat [90/149 (60.4 %) vs. 82/151 (54.3 %); P = 0.29] nor in the per-protocol analysis [90/129 (69.8 %) vs. 82/132 (62.1 %); P = 0.19]. Overall BBPS score did not differ statistical significantly in the two groups, but the provision of specific verbal instructions was associated with significant higher rates of good (58.1 % vs. 43.2 %; P = 0.02) and excellent (31.8 % vs. 16.7 %; P = 0.004) bowel preparation compared to the SOC group. Administration of same-day bowel preparation and patient American Society of Anesthesiologists score > 2 were identified as risk factors for inadequate bowel preparation. Conclusions Provision of specific verbal instructions did not increase the rate of adequate bowel preparation in a population of mobilized and bedridden hospitalized patients.

AbstractObjective: In recent years a number of articles have highlighted deficiencies in drinking histories taken by junior doctors. This study examines whether standards have improved as a result. It also examines for the first time: 1. the quality of drinking histories taken from patients following parasuicide; and 2. the quality of illicit drug usage histories.Method: An audit of case notes was undertaken of 114 patients admitted to a district hospital's acute psychiatric wards or assessed following overdose. Two periods were considered; one preceding many of the articles, and the second four years later.Results: There was an overall improvement from 58% of histories in 1988 having no mention of alcohol usage to 25% in 1992. (X2MH=10.57, p<0.01). There was, however, insufficient improvement of quantitative histories to reach statistical significance. Histories taken as part of an overdose assessment were not significantly different from those taken for inpatient admission. In 1992, 27% of patients had any illicit drug usage history recorded which represented a statistically significant improvement (X2MH=5.91, p<0.02) compared with four years earlier.Conclusions: Although improvements have been noted, alcohol and drug histories remain inadequate.
