This paper derives the probabilistic continuous review backorders and lost sales inventory system when the order cost is a function of the order quantity. Our objective is to minimize the expected annual total cost under a restriction on the expected annual holding cost when the lead time demand follows some continuous distributions by using the Lagrangian method. Some published special cases are deduced and an illustrative numerical example with some graphs is added.

This experiment research adopts ordinary portland cement with the strength grade of 42.5, mixed it with slag, fly ash and water reducing agent to prepare C40 steel fiber reinforced concrete (SFRC). Via observing the compressive strength changes of steel fiber reinforced concrete when different amount of steel fiber, slag and fly ash were mixed, reasonable amount of steel fiber was determined with the maximum compressive strength of concrete. As a result, as concentrations of minerals and sand ratio changed, the compressive strength of concrete varied regularly. In addition, when the strength was maximum, the amount of steel fiber proved to be constant with the value of 1.4%.

In this paper, we suggest and analyze a new resolvent algorithm for finding the common solutions for a generalized system of relaxed cocoercive mixed variational inequality problems and fixed point of a nonexpansive mapping in Hilbert spaces. We also prove the convergence analysis of the proposed algorithm under some suitable mild conditions. In this respect, our results present a refinement and improvement of the previously known results.

Angiotensin II (AII) type I (AT1) receptor blockers are a well known group of drug that indicated principally for the treatment of hypertension as well as for the protection of kidney function in diabetic patients. Telmisartan is a highly selective angiotensin receptor blocker, and the favourable tolerability profile of telmisartan combined with its long elimination half- life ensure the drug provides pronounced reductions in blood pressure (BP) across the entire 24-hour dosage interval. There is relatively very little data and information available to reveal renoprotective activity of telmisartan in nondiabetic low grade albuminuric Kurd hypertensive patients. Our study explores the effect of telmisartan on mean arterial blood pressure and it also sheds more light on its crucial role in lowering albumin: creatinine ratio in Kurd patients. The results of our study demonstrate that telmisartan reduces mean arterial blood pressure significantly, furthermore the study had explained a significant reduction in albuminuria at the second month of treatment which is regarded as a positive sign of renoprotection.
血管紧张素II (AII) I型(AT1)受体阻滞剂是一组众所周知的药物,主要用于治疗高血压和保护糖尿病患者的肾功能。替米沙坦是一种高度选择性的血管紧张素受体阻滞剂,其良好的耐受性及其较长的消除半衰期确保该药物在整个24小时剂量间隔内提供明显的血压(BP)降低。关于替米沙坦对非糖尿病性低蛋白尿库德族高血压患者的肾保护作用的数据和信息相对较少。我们的研究探讨了替米沙坦对平均动脉血压的影响,也揭示了它在降低库尔德患者白蛋白:肌酐比率方面的关键作用。我们的研究结果表明,替米沙坦显著降低平均动脉血压,此外,研究还解释了在治疗第二个月时蛋白尿的显著降低,这被认为是肾保护的积极迹象。

This study was aimed at strengthening primary school children’s capacities as ‘health-promoting actors’. A participatory action research (PAR) design was implemented in five semi-rural primary schools in Mahasarakham Province. Selected students were identified as health promoting targets and planned for changing themselves by following a health promoting plan with the participatory action of their families and their schools. Quantitative data and qualitative data were collected and analyzed. The qualitative results indicated that to attain the goals of HPS it is important that using student capabilities to generate ways to solve their health-related problems becomes a fundamental strategy such as students communicating with health promotion strategies from the school through the families, building a stronger relationship between teachers-families-students, and students’ capability as ‘health promoting actors’. The possible roles for school teachers and health personnel assisting HPS program can revealed in quantitative analysis. Results showed that the student’s knowledge of health promoting school significantly decreased from before the training course (P < 0.001) The mean score of HPS knowledge after experiment was higher than before the experiment which are the HPS training scores (M = 9.5319, SD = 1.62) was significantly higher than before attending (M = 8.4681, SD = 1.52; t = - 6.173, p = < 0.001) HPS course. The result of this study using Home Visit can increase the participatory actions among Primary School students, teachers, family members. It can lead to more benefits in individual self efficacy and the development of healthcare among societies.

We introduce the Jungck-multistep-SP iteration and prove some convergence as well as stabiilty results for a pair of weakly compatible generalized contractive-like inequality operators defined on a Banach space. As corollaries, the results show that the Jungck-SP and Jungck-Mann iterations can also be used to approximate the common fixed points of such operators. The results are improvements, generalizations and extensions of the work of Chugh and Kumar (2011). Consequently, several results in literature are generalized. Key words : Jungck-multistep-SP iteration

A quaternionic mass defining longitudinal mass () and transverse mass () of a particle is introduced. The longitudinal and transverse masses represent the mass of the particle and matter wave accompanying it, respectively. A massive particle is found to have a bigger longitudinal mass than transverse mass. The particle nature due to the transverse mass of a particle is described by a scalar wave satisfying the Klein-Gordon equation. The transverse mass vector is found to be along the direction of the particle’s velocity (). A particle of an equal longitudinal and transverse mass travels at speed of light in vacuum. The transmission of matter wave energy is found to be opposite to the particle velocity. The momentum of the particle () and its matter wave () are equal. The direction of the transverse mass is found to be along the direction of the particle’s velocity.

Objectives : Actinidic archaea have been related to the pathogenesis of metabolic syndrome x. An actinide dependent shadow biosphere of archaea and viroids has been described in metabolic syndrome x with type 2 diabetes mellitus. Actinidic archaea have a mevalonate pathway and are cholesterol catabolizing. They can use cholesterol as a carbon and energy source. Archaeal cholesterol catabolism can generate porphyrins via the cholesterol ring oxidase generated pyruvate and GABA shunt pathway. Archaea can produce a secondary porphyria by inducing the enzyme heme oxygenase resulting in heme depletion and activation of the enzyme ALA synthase. Porphyrins have been related to metabolic syndrome x and type 2 diabetes mellitus. The role of archaeal porphyrins in regulation of cell functions, metabolism and endocrine function is discussed. Porphyrins play a key role in the generation of the Warburg phenotype, endogenous digoxin synthesis and metabolic syndrome x with type 2 diabetes mellitus.  Methodology : The following groups were included in the study: - metabolic syndrome x with cerebrovascular thrombosis and coronary artery disease. There were 10 patients in each group and each patient had an age and sex matched healthy control selected randomly from the general population. The blood samples were drawn in the fasting state before treatment was initiated. Plasma from fasting heparinised blood was used and the experimental protocol was as follows (I) Plasma + phosphate buffered saline, (II) same as I + cholesterol substrate, (III) same as II + rutile 0.1 mg/ml, (IV) same as II + ciprofloxacine and doxycycline each in a concentration of 1 mg/ml. The following estimations were carried out: - Cytochrome F420, free RNA, free DNA, polycyclic aromatic hydrocarbon, hydrogen peroxide, pyruvate, ammonia, glutamate, succinate, glycine, delta aminolevulinic acid and digoxin. The study also involved estimating the following parameters in the patient population- hexokinase, porphyrins, pyruvate, glutamate, ammonia, succinic acid, serine, glycine, HMG CoA reductase, cytochrome C, blood ATP and heme oxygenase. Results : Plasma of control subjects showed increased levels of the above mentioned parameters with after incubation for 1 hour and addition of cholesterol substrate resulted in still further significant increase in these parameters. The plasma of patients showed similar results but the extent of increase was more. The addition of antibiotics to the control plasma caused a decrease in all the parameters while addition of rutile increased their levels. The addition of antibiotics and rutile to the patient’s plasma produced the same changes but the extent of change was more in patient’s sera as compared to controls. There was upregulated archaeal porphyrin synthesis in the patient population which was archaeal in origin as indicated by actinide catalysis of the reactions. The cholesterol oxidase pathway generated pyruvate which entered the GABA shunt pathway. Thi
目的:锕系古细菌与代谢综合征x的发病机制有关,在2型糖尿病合并代谢综合征x中发现了一个依赖锕系元素的古细菌和类病毒的阴影生物圈。放线菌具有甲羟戊酸途径和胆固醇分解代谢。它们可以利用胆固醇作为碳和能量的来源。古菌胆固醇分解代谢可通过胆固醇环氧化酶生成丙酮酸和GABA分流途径生成卟啉。古生菌可以通过诱导血红素加氧酶导致血红素耗竭和ALA合成酶激活而产生次生卟啉症。卟啉与代谢综合征x和2型糖尿病有关。讨论了古细菌卟啉在调节细胞功能、代谢和内分泌功能中的作用。卟啉在Warburg表型的产生、内源性地高辛合成和代谢综合征x伴2型糖尿病中起关键作用。方法:以下组被纳入研究:代谢综合征x合并脑血管血栓形成和冠状动脉疾病。每组有10名患者,每名患者从普通人群中随机选择年龄和性别匹配的健康对照。在治疗开始前,在禁食状态下抽取血样。使用空腹肝素化血血浆,实验方案如下:(I)血浆+磷酸盐缓冲盐水,(II)与I +胆固醇底物相同,(III)与II +金红石0.1 mg/ml相同,(IV)与II +环丙沙星和多西环素浓度均为1mg /ml相同。对细胞色素F420、游离RNA、游离DNA、多环芳烃、过氧化氢、丙酮酸、氨、谷氨酸、琥珀酸、甘氨酸、氨基乙酰丙酸和地高辛进行了估计。该研究还涉及估计患者人群中的以下参数-己糖激酶、卟啉、丙酮酸、谷氨酸、氨、琥珀酸、丝氨酸、甘氨酸、HMG辅酶a还原酶、细胞色素C、血液ATP和血红素加氧酶。结果:对照组在孵育1小时后,血浆中上述参数升高,添加胆固醇底物后,上述参数进一步显著升高。患者血浆也有类似结果,但升高幅度更大。在对照血浆中添加抗生素使各项指标均下降,而添加金红石使各项指标升高。在患者血浆中添加抗生素和金红石也产生了同样的变化,但与对照组相比,患者血清中的变化程度更大。古菌卟啉合成在患者群体中有上调,其来源是古菌,锕系元素催化反应表明。胆固醇氧化酶途径产生丙酮酸进入GABA分流途径。这导致琥珀酸盐和甘氨酸的合成,它们是ALA合酶的底物。研究表明,患者血液中的血红素加氧酶活性增加,丝氨酸、甘氨酸、琥珀酸和卟啉增加。己糖激酶活性高。丙酮酸、谷氨酸、氨、GABA和琥珀酸水平升高,表明PDH活性被阻断,GABA分流通路运行。血清中细胞c水平升高,提示低血ATP水平提示线粒体功能障碍。这表明了Warburg的表型。HMG CoA还原酶活性高,表明胆固醇合成。RHCD人群的值与患者人群相似。而LHCD人群的数值则相反。结论:代谢综合征合并冠状动脉和脑血管疾病中古细菌和类病毒存在锕系依赖的阴影生物圈。卟啉可能参与代谢综合征x合并冠状动脉和脑血管疾病的发病机制。卟啉合成在这些疾病的发病机制中起着至关重要的作用。卟啉可以作为调节分子调节免疫、神经、内分泌、代谢和遗传系统。卟啉光氧化产生的自由基可以产生免疫活化,产生细胞死亡,激活细胞增殖,产生胰岛素抵抗和调节意识/量子感知。卟啉可以调节半球优势。古细菌卟啉是线粒体苯二氮卓类受体的重要调控分子。关键词:锕系元素;古菌;卟啉;GABA分流;外周苯二氮卓受体;氨基乙酰丙酸;代谢综合征;2型糖尿病;冠状动脉疾病;脑血管疾病

Archaeal cholesterol catabolism can generate porphyrins via the cholesterol ring oxidase generated pyruvate and GABA shunt pathway. Archaea can produce a secondary porphyria by inducing the enzyme heme oxygenase resulting in heme depletion and activation of the enzyme ALA synthase. Porphyrins have been related to metabolic syndrome x and type 2 diabetes mellitus. The role of archaeal porphyrins in regulation of cell functions, metabolism and endocrine function is discussed. Porphyrins play a key role in the generation of the Warburg phenotype, endogenous digoxin synthesis and metabolic syndrome x with type 2 diabetes mellitus.  Methodology : The following groups were included in the study: - metabolic syndrome x with cerebrovascular thrombosis and coronary artery disease. There were 10 patients in each group and each patient had an age and sex matched healthy control selected randomly from the general population. The blood samples were drawn in the fasting state before treatment was initiated. Plasma from fasting heparinised blood was used and the experimental protocol was as follows (I) Plasma + phosphate buffered saline, (II) same as I + cholesterol substrate, (III) same as II + rutile 0.1 mg/ml, (IV) same as II + ciprofloxacine and doxycycline each in a concentration of 1 mg/ml. The following estimations were carried out: - Cytochrome F420, free RNA, free DNA, polycyclic aromatic hydrocarbon, hydrogen peroxide, pyruvate, ammonia, glutamate, succinate, glycine, delta aminolevulinic acid and digoxin. The study also involved estimating the following parameters in the patient population- hexokinase, porphyrins, pyruvate, glutamate, ammonia, succinic acid, serine, glycine, HMG CoA reductase, cytochrome C, blood ATP and heme oxygenase. Results : Plasma of control subjects showed increased levels of the above mentioned parameters with after incubation for 1 hour and addition of cholesterol substrate resulted in still further significant increase in these parameters. The plasma of patients showed similar results but the extent of increase was more. The addition of antibiotics to the control plasma caused a decrease in all the parameters while addition of rutile increased their levels. The addition of antibiotics and rutile to the patient’s plasma produced the same changes but the extent of change was more in patient’s sera as compared to controls. There was upregulated archaeal porphyrin synthesis in the patient population which was archaeal in origin as indicated by actinide catalysis of the reactions. The cholesterol oxidase pathway generated pyruvate which entered the GABA shunt pathway.

This research is a descriptive and explorative study and is aimed at defining the composition and indication of Thai traditional herbal medicinal preparations which were derived from the ancient Thai medicinal of palm leaf scriptures, chapter no.3, and volume 5. The research was investigated by the team of Mahasarakham University committee which consisted of pharmacist, biologists, interpreters and editors. The complete manuscripts contained 5 volumes in Thai Noi, Tham Esarn, khemer and Thai traditional languages. Each traditional medicinal herb diagnosed the symptoms of the patients and treats them with herbal preparations according to their local herbal medicinal knowledge and experiences in order to relieve various symptoms and diseases. These historic formulations were created over a period of hundreds of years before the advent of modern medicine. Key words : Palm leaf manuscripts; Therapeutic treatments; Thai Folk Herbalists

The impact of information and communication technologies in bringing about a profound transformation in all aspects of national life in the world over does not need to be over stressed anymore. Information and communication technologies heralds a fundamental change in the dissemination of information with regard to among other things, economic, business and education. Ultimately, this paper attempts to give an overview of current initiatives around ICTs, and university development through a review of available literature. The overview will be followed by a selection of case studies of Ajayi Crowther University, documenting initiatives where ICT plays a prominent role and suggestions for further research and projects to inspire discussion for future research programme. This is part of a process to develop research programme exploring ICT innovations in, and the consequences of their possible application to university development. ICTs and university development are extensive fields, and it is not possible to address all aspects in this paper but only what has been found to be of greatest current importance. When applying ICT to university development, it has been found that the most important challenges that institutions are currently facing are the responsibilities that have been transferred to them through recent decentralization. In this paper this aspect will thus be deliberately focused upon along with the ICTs that are of most relevant to these institutions meeting their new responsibilities.
