Background: Birth asphyxia is one of the major causes of neonatal deaths worldwide. Queen Elizabeth Central Hospital (QECH) neonatal ward records indicate that 36.5% of neonates admitted in the ward from April to September 2012 had birth asphyxia. This study was conducted to explore associative factors for birth asphyxia at QECH. Methodology: The study design was descriptive cross sectional that employed quantitative methods of data collection and analysis. Data sources were case notes of neonates and their mothers. Sample size was 87 neonates with birth asphyxia and 87 neonates admitted with conditions other than birth asphyxia as controls. Data were collected from November to December 2013. Statistical Package for Social Science (SPSS) version16.0 was used to analyze data. Results: Findings revealed that there were no maternal associative factors for birth asphyxia, however, foetal distress, prolonged first and second stage of labour were significant associative factors for birth asphyxia. Conclusion: Associative factors for birth asphyxia at QECH are Foetal distress, prolonged first and second stage of labour. These factors can be prevented if quality care is provided to women in labour through close monitoring of foetal heart, appropriate use of the partograph, prompt decision making and early interventions.

Formation of Eutectic Carbides in the Structure of High-Purity White Cast Iron in the Forging Process

Authors: D. A. Sukhanov, L. B. Arkhangelsky

It is found that the deformation of white cast iron under forging production is only possible with a minimum number of permanent impurities. The developed modes of high-temperature intermediate annealing facilitate the deformation of the forging under normal production conditions. It is shown that in the process of isothermal annealing of white cast iron begins the process of disintegration of ledeburite in the more stable eutectic carbides, providing technological plasticity for subsequent forging. The installed influence of the purity of white cast iron on the morphology of the excess carbides and their ability to divide. Studies the morphology of the excess eutectic carbides after melting, pre-annealing and after deformation forging. Discovered that after severe plastic deformation the structure of white cast iron becomes more stable, due to the appearance of eutectic carbides. It was determined that the deformed structure of white iron, because of its lack ledeburite component, was more identical with the structure of the alloy ledeburite steels. The data obtained can be used for making Damascus bladed weapons products, experiencing shock-variables loads.

A Final Solution to the Mind-Body Problem by Quantum Language

Author: Shiro Ishikawa

Recently we proposed “quantum language”, which was not only characterized as the metaphysical and linguistic turn of quantum mechanics but also the linguistic turn of Descartes = Kant epistemology. And further we believe that quantum language is the only scientifically successful theory in dualistic idealism. If this turn is regarded as progress in the history of western philosophy (i.e., if “philosophical progress” is defined by “approaching to quantum language”), we should study the linguistic mind-body problem more than the epistemological mind-body problem. In this paper, we show that to solve the mind-body problem and to propose “measurement axiom” in quantum language are equivalent. Since our approach is always within dualistic idealism, we believe that our linguistic answer is the only true solution to the mind-body problem.

Author: Jiayi Zhao

Bearing the responsibility of the rising strategy of central region of China, Changsha-Zhuzhou-Xiangtan Urban Agglomeration is an important growth pole of the development of the Yangtze river economic belt. Reasonable position of urban function in Changsha-Zhuzhou-Xiangtan Urban Agglomeration, is an inevitable requirement for the cooperative development of regional economy in Changsha, Zhuzhou and Xiangtan. This paper takes the basic economic activities of these cities as the starting point to determine the urban function. Subsequently, this paper uses the related statistical data, introduces multivariate statistical analysis method, such as regression analysis, factor analysis and cluster analysis to clarify the function of 20 cities in Changsha-Zhuzhou-Xiangtan Urban Agglomeration. The findings reveal that the most common functions of the regional urban agglomeration are construction, transportation, postal services, finance, real estate, manufacturing, social services, wholesale and retail industry. At the same time, the paper classifies these 20 cities according to the urban function. The classification results provide the basis for accelerating Changsha-Zhuzhou-Xiangtan Urban Agglomeration construction of urban function.

Effects of Post-Weaning Consumption of Soy Isoflavones on Prepubertal and Postpubertal Serum Levels of Some Reproductive Hormones of Male Wistar Rats

Authors: Ssimbwa Godfrey, Eze Ejike Daniel, Sheu Sulaiman Oluwadare, Begumya Yovani

Chemically, soy contains a group of phytoestrogens called isoflavones, pre-dominantly genistein and daidzein. The aim of the present study was to determine the effects of post weaning consumption of dietary soy isoflavones on prepubertal and postpubertal serum levels of some reproductive hormones of male Wistar rats. The study involved investigating the effects of different doses of isoflavones in the diet. Male rats were weaned on either soy isoflavone free diet or on isoflavone containing diets, formulated by adding increasing amounts of Novasoy, a commercially available isoflavone supplement to the isoflavone free diet to give varying concentrations of isoflavones. Three isoflavone containing diets were used and these had 74.5, 235.6 and 1046.6 mg total isoflavones/kg pelleted diet. These diets represented the isoflavone concentration lower, equal to and more than that found in soy-based infant formulas respectively. Continue reading

A New Augmented Lagrangian Objective Penalty Function for Constrained Optimization Problems

Authors: Ying Zheng, Zhiqing Meng

In this paper, a new augmented Lagrangian penalty function for constrained optimization problems is studied. The dual properties of the augmented Lagrangian objective penalty function for constrained optimization problems are proved. Under some conditions, the saddle point of the augmented Lagrangian objective penalty function satisfies the first-order Karush-Kuhn-Tucker (KKT) condition. Especially, when the KKT condition holds for convex programming its saddle point exists. Based on the augmented Lagrangian objective penalty function, an algorithm is developed for finding a global solution to an inequality constrained optimization problem and its global convergence is also proved under some conditions.

An Experimental Study of the Atmospheric Oxidation of a Biogenic Organic Compound (Methyl Jasmonate) in a Thin Water Film as in Fog or Aerosols

Authors: Aubrey A. Heath, Kalliat T. Valsaraj

Experiments on the reactions of OH radicals in thin films of water were conducted in a photochemical reactor. The OH radical reactivity of a biogenic molecule (methyl jasmonate) was observed to be much larger in thin films of water than in the bulk aqueous phase. The pseudo-first order reaction rate was enhanced by an order of magnitude on a 38-micron film compared to the bulk liquid. However, the first order rate constant increased by 349%. This has implications in atmospheric systems like fog and mist which have large specific surface areas. The enhanced reactivity is attributable to both the partial solvation and faster diffusion at the air-water interface compared to the bulk liquid.

A Basic Study of the Forecast of Air Transportation Networks Using Different Forecasting Methods

Authors: Yuya Takahashi, Rie Osawa, Susumu Shirayama

This research applies network structuring theories to the aviation domain and predicts aviation network growth, considering a flight connection between airports as a link between nodes. Our link prediction approach is based on network structure information, and to improve prediction accuracy, it is necessary to estimate the mechanism of aviation network growth. This research critically evaluates the prediction accuracy of two methods: the receiver operating characteristic curve method (ROC) and the logistic regression method. We propose a four-step method to evaluate the relative predictive accuracy among different link prediction methods. A case study of US aviation networks indicated that the ROC method provided better prediction accuracy compared with the logistic regression method. This result suggests that tuning of the prediction distribution and the regression model coefficients can further improve the accuracy of the logistic regression method.

Surgical Treatment of Idiopathic Multiple Pulmonary Arteriovenous Malformation Identified at the Onset of Cerebral Infarction: A Case Report

Authors: Masahiro Kitada, Shunsuke Yasuda, Nana Takahashi, Satoshi Okazaki,
Kei Ishibashi, Satoshi Hayashi, Yoshinobu Ohsaki

Pulmonary arteriovenous malformation (PAVM), which is asymptomatic in most cases, is often identified in patients with central nervous system disorders such as brain abscesses and/or cerebral infarctions. We have reported a patient with idiopathic multiple PAVM identified at the onset of cerebral infarction. A 69-year-old woman visited the Department of Neuropathic Internal Medicine at our hospital with chief complaints of numbness in her left hand and a feeling of weakness. The patient was given a diagnosis of subacute cerebral infarction. Multiple old lacunar infarctions were also observed in the deep white matter of the left frontal lobe. Chest computed tomography showed multiple nodular structures, mainly in the right lower lung field (S8), as well as continuous arteries and veins at the site; thus, the patient was finally diagnosed with multiple PAVM. Right lower thoracoscopic lobectomy was performed, as is typical surgical practice in such cases. The patient had a favorable postoperative course, and had no recurrence of cerebral infarction. Although the patient’s lesions were mainly restricted to S8, the fact that there were multiple lesions deemed a lobectomy as the appropriate course of treatment. This case emphasizes that attention should be paid to cases of multiple PAVM since cerebral infarction may arise from the disease.
