福島第一原子力発電所事故で放射性物質が多量に降下してから約2か月後に,耕起されていない水田の深さ15cmまでの表土を厚さ1~5cmの6層に分割してサンプリングし,放射性セシウム(134Csと137Cs)の鉛直濃度分布を求めた結果,放射性Csの88%が0~3cmに,96%が0~5cmに止まっていた。しかし,量的に大半は表面付近に存在するものの,15~20cmの層まで新たに降下した放射性Csの影響が及んでいた。濃度分布から求めた放射性Csの平均移動距離は約1.7cmで,70日間の雨量(148mm)から蒸発散量を引いて体積含水率で割った水分子の平均移動距離は約20cmと推定され,土壌への収着により,Csの移流速度は水の移流速度に比べて1/10であった。しかし,文献にみられる実験室で測定した収着平衡時の土壌固相と土壌水との間の分配係数から計算される移流速度よりは2~3桁大きく,現場の移動現象が収着平衡からほど遠いことを示している。一方,耕起された水田では,表層の高濃度の放射性セシウムが0~15cmの作土層内に混合されて平均値(約4000Bq/kg)となっていた。
The mechanics of crack formation and the influence soil stress history were described using tip opening angle (CTOA) measured with fractography. Two soils studied: a model consisting 40% Ca‐bentonite 60% fine silica sand remolded paddy similar clay content mineralogy. Fracture testing used deep‐notch bend specimens formed by molding at liquid limit into rectangular bars, equilibrating to water suction ranging from 5 kPa 50 (with some wetted kPa), inserting 0.4× specimen thickness. Bend tests...
Core Ideas Paddy soil shrinkage behaviors and cracking patterns were significantly influenced by wetting drying cycles. Wetting (WD) intensity had a greater impact on than WD frequency sequence. The crack area can be better predicted curve when considering geometry factor is linked to cracking. Linking Soil cracks develop in paddy soils during Although changes structure related have often been described as shrinkage, the relationship between remains unclear. objectives of this study...
Transseptal puncture (TSP) has become a common approach in catheter ablation of arrhythmia originating from the left atrium. In paediatric patients, however, TSP can be challenge due to narrower access vessels and small atrial size, safety smaller children is yet understood. The purpose this study was retrospectively evaluate feasibility weighing below 30 kg.Among 655 patients who underwent between July 2009 April 2015, 43 cases having structurally normal hearts, <30 kg requiring were...
Percutaneous occlusion of atrial septal defect (ASD) has recently become a standard therapeutic strategy, but little is known about left (LA) function thereafter. The present study aimed to determine LA in 43 children with ASD and 13 controls based on strain measured by two-dimensional echocardiographic speckle tracking (2DE-ST). Among these children, 12 underwent surgery (ASD-S), 31 had device closure (ASD-D), were included as controls. was significantly decreased after ASD-D not altered...
Abstract Shrinkage cracks in clayey paddy fields are major pathways for the drainage of excess water through tile drainage. In this study, factors that affect cracking pattern were investigated a field where paddy-rice was planted rows. The examined included 1) existence transpiration, 2) row spacing, and 3) puddling intensity. experiment designed according to Taguchi method experimental design. induced by drying after release ponding mid-summer. patterns between rows recorded on transparent...
The clinical effectiveness and side effects of DL-8280 in the treatment lower respiratory tract infections including pneumonias were compared with those amoxicillin (AMPC) by a double-dummy fashion.The following diseases included this study; infectious exacerbation chronic bronchitis diffuse panbronchiolitis, (bronchiectasis, bronchial asthma, pulmonary emphysema, lung fibrosis, inactive tuberculosis) various kinds bacterial pneumonias.Two hundred mg dose was orally administered 3 times per...
Acid sphingomyelinase (ASM) is a lysosomal enzyme that hydrolyzes sphingomyelin into ceramide, bioactive lipid to regulate cellular physiological functions. Thus, ASM activation has been reported as key event in pathophysiological reactions including inflammation, cytokine release, oxidative stress, and endothelial damage human diseases. Since associated with extracellular secretion through unknown mechanisms, it can be detected by recognizing the elevation of secretory (S-ASM) activity....
The clinical efficacy and safety of ofloxacin (OFLX; DL-8280) cefaclor (CCL) were compared bya double-blind study using 250 patients with bacterial bronchitis. Patients orally administered witheither 200 mg OFLX or CCL three times a day for 14 days, the following results wereobtained.1) Clinical judged by committee:The rate acute bronchitis was 86.7% in group 85.7% group. On theother hand, 78.4% 50.0% those effective inchronic Statistically significant difference observed between andCCL...
The ratio of the diffusion coefficient a solute in soil to bulk water ( D r ) has been shown be proportional volumetric content (θ) power n , and studies dependency on θ have that is approximately 2. This value can explained physically using simple tortuosity model. However, values 4 found two soils (sandy loamy) with low contents, these high attributed an electrically diffuse double layer formed near charged solid surfaces, restricting ion within it. We examined effect electrical charge...
Abstract The occurrence of water ponding on soil surfaces during and after heavy rainfall produces surface run‐off or accumulation in low‐lying areas, which might reduce the supply to soils result a reduction that plants can use, especially arid climates. On Mongolian rangeland, we observed ponded specific condition subjected 30 mm/hr. By contrast, was not for same type where livestock grazing had been removed 6–8 years via fence nearby containing less clay. We measured infiltration rate...
Background Left ventricular noncompaction (LVNC) is a hereditary type of cardiomyopathy characterized by prominent trabeculations. Detailed characteristics biventricular (BiVNC) remain unknown. This study aimed to elucidate the clinical and genetic landscape BiVNC. Methods Results We recruited children with left from Japanese multi‐institutional centers 2013 2021. was classified as BiVNC, congenital heart disease, arrhythmia, dilated cardiomyopathy, or normal function. In these patients,...
