The results of fundamental experiments revealed that the coal filled in a pipe was moved by low water pressure, and it flowed in a pipeline with little delay when velocity of stream exceeded 3.5m/s. According to these results a multi-pipe type coal feeder was invented. It consists of several parallel long lock chambers which are branched from a delivery pipe of a high pressure pump. And they have approximately the same diameter of the conveying pipe. One of these is fed coal and water mixture by means of a low pressure sand pump. After this, the mixture is pushed into the conveying pipe by the high pressure water. This process is repeated one after another, and coal is transported continuously.The auther produced a hand-operated model of this coal feeder for laboratory tests, then made its valves act automatically. The practical tests of this feeder was carried out at Yoshima colliery. 20.000t of coal was transported by 7 in. pipeline with it. The test results revealed that it had the transporting capacity of 100t/h, registering the volume concentration 20% Now the test is continued on commercial basis at Sunagawa colliery. The transportation height is 490m and the length of pipeline 2, 046m. There automatic control of concentration of coal in the pipeline is attemped to economize the transportation cost.

This paper analyzes the feasibility of introducing a bus rapid transit (BRT) system and the restructuring of the bus route network to improve the performance of the local bus service in Yangon, Myanmar. First, we summarize the characteristics of the current urban bus service in Yangon. We point out that the point-to-point bus route network results in many overlapping routes along main roads and this leads to serious traffic congestion. Then, we examine the feasibility of two policy options. The first case (Case 1) introduces a new BRT line to the existing bus network; while the second case (Case 2) restructures the bus route network whilst introducing a new BRT line. Five types of BRT fares are considered for each case. To evaluate these policy options, a travel demand forecast system, including the estimation of an origin-destination table and a bus route-choice model, is developed. The results of the evaluation show that Case 1-400, in which a new BRT with a flat fare of 400 Kyats, introduced to the existing bus route network offers the most desirable outcome.

One can relativize one's own environmental values by comparison with those of the people in other countries, thereby recognizing that these values are indispensable for sustainable development in each country. This study, which focused on Russia and Japan, aimed to clarify the commonality, differences, and factors influencing environmental attitudes, concerns, and a sense of value. Within the two countries, we selected seven universities as research sites and interviewed 282 respondents using three questionnaires. Respondents in both Japan and Russia showed a relatively strong concern and positive attitude toward environmental issues. However, those in Russia were relatively more concerned. Both countries showed a high sense of value regarding the maintenance and preservation of ecosystems; however, respondents in Russia generally valued ecocentrism over anthropocentrism. Gender was found to be the strongest influence on indicators, followed by research sites, age, and faculty.

Advanced glycation end-products are toxic by-products of metabolism and are also acquired from high-temperature processed foods. They promote oxidative damage to proteins, lipids and nucleotides. Aging and chronic diseases are strongly associated with markers for oxidative stress, especially advanced glycation end-products, and resistance to peripheral insulin-mediated glucose uptake. Modifiable environmental factors including high levels of refined and simple carbohydrate diets, hypercaloric diets and sedentary lifestyles drive endogenous formation of advanced glycation end-products via accumulation of highly reactive glycolysis intermediates and activation of the polyol/aldose reductase pathway producing high intracellular fructose. High advanced glycation end-products overwhelm innate defenses of enzymes and receptor-mediated endocytosis and promote cell damage via the pro-inflammatory and pro-oxidant receptor for advanced glycation end-products. Oxidative stress disturbs cell signal transduction, especially insulin-mediated metabolic responses. Here we review emerging evidence that restriction of dietary advanced glycation end-products significantly reduces total systemic load and insulin resistance in animals and humans in diabetes, polycystic ovary syndrome, healthy populations and dementia. Of clinical importance, this insulin sensitizing effect is independent of physical activity, caloric intake and adiposity level.

Cancer is a leading cause of death worldwide. The Western dietary pattern is an established risk factor for many cancers, particularly for colorectal cancer (CRC). The Western diet is typified by the high consumption of red and processed meats, high fat foods, sugary foods and refined grains, whereas a more prudent diet replaces these foods with whole grains, fruits and vegetables, many of which are rich in dietary bioactives known to reduce cancer risk. Agricultural production of many of the foods common to the Western diet is also estimated to have a high environmental impact. Thus, diet modification to reduce cancer risk by consumption of more fruits and vegetables would also be considered a more environmentally sustainable diet.This review summarizes the impact of dietary bioactives on gastrointestinal health, with a focus on the role of the gut microbiome and intestinal inflammation in colorectal carcinogenesis. Four dietary bioactives with purported anti-cancer activities are discussed, including catechins (green tea), anthocyanins (red/blue berries), proanthocyanidins (cocoa) and isoflavones (soy), with special consideration given to evidence for their interaction with the gut microbiome. The review concludes with a proposed model for investigating the impact of dietary bioactives for prevention of colon cancer that incorporates the Western nutritional pattern and considers the role of human gut microbiota in pre-clinical studies.

A climatic regime shift is characterized by an abrupt transition from one quasi-steady climatic state to another. We attempted to explain the change of multifractal behavior of climate indices when a regime shift occurred. We used the wavelet - transform method to analyze the multifractal behaviors of the El Niño/Southern Oscillation (ENSO) index (Niño3.4 index), Pacific Decadal Oscillation (PDO) index, North Pacific Index (NPI), Pacific/North American pattern (PNA) index, and West Pacific pattern (WP) index. We showed the change of multifractality of these climate indices. When the wavelet coherences between the Niño3.4 index and NPI, NPI and PDO index, and Niño3.4 and PDO indices became strong, changes from multifractal to monofractal behavior were observed at climatic regime shifts. It may be possible to explain the background of the change of fractality by regarding climate change as the consequence of mutual interactions of various climatic elements. A fluctuation increase is observed in a coupled chaotic system just before chaos synchronization, which is when fractality and states change. We expect that a similar mechanism possibly exists for a climatic regime shift. When fluctuations became large and multifractality became strong, a climatic regime shift occurred and a change from multifractal to monofractal behavior was observed. The strong interaction of climatic phenomena, such as the ENSO, PDO, and Aleutian Low, caused a climatic regime shift. The fractality change of the PDO index almost corresponded to the regime shifts. In terms of multifractal analysis, we conclude that a climatic regime shift corresponds to a change from multifractality to monofractality of the PDO index.

小説を読む場合には,しばしば裏表紙などに書かれた紹介文を参考として図書を選択することが行われる。しかし実際には,紹介文を読んだ時に期待したものとは異なる感想を持つ結果となることも少なくない。このような齟齬の原因としては,小説に対する感想の個人差がある場合のほか,読書前後で図書に対して注目する観点が異なることも考えられる。本研究では,読書前にこのような感想を持つだろうと予想して作成された文章と,読書後に実際に作成された文章(感想文)との比較を行い,読書前後で観点が変化するかどうかを調査した。10冊の小説を対象として読書前後に作成された文章の中に出現する語の品詞や意味の種類の分析を行ったところ,出現する語の品詞や意味の種類は読書前後で共通であり,読書前後での観点そのものには大きな違いはないことが明らかとなった。

[Purpose] This study aimed to investigate the effects of prone bridge exercise on trunk muscle thickness. [Subjects and Methods] Thirty-seven chronic low back pain patients participated in this study. Each participant was randomly assigned to one of three exercise groups, namely, a prone bridge exercise group, supine bridge exercise on a Swiss ball group, and supine bridge exercise group. The thicknesses of the transverse abdominis (TrA), internal oblique (IO), and external oblique (EO) were measured using ultrasound. [Results] After eight weeks of training, the three groups showed significant increases in the thicknesses of the TrA, IO, and EO. Among the groups, TrA and IO showed significantly different muscle thicknesses. [Conclusion] The prone bridge exercise significantly affected the thicknesses of the TrA, IO, and EO unlike the supine bridge exercises. Based on the results of this study, the prone bridge exercise is a more effective method to improve trunk stability than conventional supine bridge exercises.

This study evaluated anesthesia quality, degree of analgesia, and cardiorespiratory parameters after intramuscular (IM) injection of a combination of butorphanol (0.1 mg/kg), medetomidine (10 µg/kg), and alfaxalone (1.5 mg/kg) in ten healthy adult Beagle dogs. Rectal temperature (T), heart rate (HR), respiratory rate (fR), arterial pressure, arterial blood gases, and M-mode echocardiographic left ventricular (LV) indices were measured before drug administration and every 10 min thereafter until extubation. Mean duration of anesthesia, recovery, and analgesia were 89 ± 17, 6 ± 1, and 80 ± 12 min. HR, fR, partial pressure of arterial CO2 and O2, arterial pressure, and LV contractility were significantly altered during anesthesia. IM administration of the drug combination provided acceptable anesthesia, but produced substantial cardiorespiratory suppression.

Arterial blood gas analysis is an important diagnostic and monitoring tool for respiratory abnormalities. In human medicine, lung complications often occur as a result of liver disease. Although pulmonary complications of liver disease have not been reported in dogs, we have frequently encountered hypoxemia in dogs with liver disorders, especially extrahepatic biliary obstruction. In addition, respiratory disorders account for 20% of perioperative fatalities in dogs. Therefore, in this study, we evaluated the respiratory status in dogs with hepatobiliary disease by arterial blood gas analysis. PaO2 and PaCO2 were measured. Alveolar-arterial oxygen difference (AaDO2), the indicator of gas exchange efficiency, was calculated. Compared to healthy dogs (control group), hepatobiliary disease dogs had significantly lower PaO2 and higher AaDO2. Hypoxemia (PaO2 of ≤80 mmHg) was observed in 28/71 dogs with hepatobiliary disease. AaDO2 was higher (≥30 mmHg) than the control group range (11.6 to 26.4 mmHg) in 32/71 hepatobiliary disease dogs. By classifying type of hepatobiliary disease, dogs with extrahepatic biliary obstruction and chronic hepatitis showed significantly lower PaO2 and higher AaDO2 than in a control group. Dogs with chronic hepatitis also had significantly lower PaCO2. The present study shows that dogs with hepatobiliary disease have respiratory abnormalities more than healthy dogs. Preanesthetic or routine arterial blood gas analysis is likely beneficial to detect the respiratory abnormalities in dogs with hepatobiliary disease, especially extrahepatic biliary obstruction and chronic hepatitis.
