New hyper-K‰hler structures on tangent bundles

Let (M;g;J) be an almost Hermitian manifold, then the tangent bundle TM carries a class of naturally dened almost hyper-Hermitian structures (G;J1;J2;J3). In this paper we give conditions under which these almost hyper-Hermitian structures (G;J1;J2;J3) are locally confor- mal hyper-K‰hler. As an application, a family of new hyper-K‰hler struc- tures is obtained on the tangent bundle of a complex space form. Further- more, by restricting these almost hyper-Hermitian structures on the unit tangent sphere bundle T1M, we obtain a class of almost contact metric 3- structures. By virtue of these almost contact metric 3-structures, we nd a family of Sasakian 3-structures on the unit tangent sphere bundle of a complex space form of positive holomorphic sectional curvature.
Exploration of Factors Influencing on Choice the Activity-Based Costing System in Iranian Organizations

As a tool for planning and control, costing systems play a considerable role in providing information needs for managers. Given the diversity of costing systems and simultaneous advancement of new costing systems, choosing a costing system may challenge managers. This research seeks to explore such organizational factors as organization size, industry type, cost structure, the importance of cost information, and products and services diversity on adopting Activity-Based costing (ABC) system in the listed companies of the Tehran Stock Exchange. Using logistic regression model from 33.5% of respondents in the sample, the results of this survey study indicates a positive relationship among cost structure, the importance of cost information and products and services diversity (in term of products and services liner numbers). It also indicates a negative relationship among the type of industry, organization size and product and services diversity (in terms of support diversity and volume diversity) with adopting the mentioned system. There was not any significant relationship between above organizational factors and choice of the ABC system.
The fluorescence yield of air excited by electrons measured with the AIRFLY experiment

A very direct way to observe ultra high energy cosmic rays is the fluorescence technique. Fluorescence detectors are already used in various experiments since the early eighties, the latest being the Pierre Auger Observatory. The most important parameter for the description of the fluorescence light detected is the fluorescence yield that defines how much light a particle causes on its way through gas. The fluorescence yield depends on temperature, pressure, gas composition and energy of the exciting particle. Also, the fluorescence yield is a major source of uncertainty in the reconstruction of the primary energy, because up to now its value is only determined within around 15%. This thesis describes the AIRFLY experiment that was set up to determine the fluorescence yield precicely. The pressure dependence of 18 spectral lines in the range of 280 nm to 430 nm has been determined using high resolution spectra. The spectral distribution of the fluorescence light in air has been measured and the effect of argon has been found to be negligible. The proportionality of the fluorescence yield to the energy deposit of the electrons has been confirmed between 1 MeV and 3 MeV. Adopting an absolute scale for the fluorescence yield at 337 nm as given by Nagano et al., the consequences of this works results for cosmic-ray measurements has been investigated.
a prospective randomized clinical study of comparing low pneumoperitoneum pressure versus standard pressure for reduction of shoulder tip pain in laparoscopic cholecystectomy

Introduction: Laparoscopic Cholecystectomy (LC) is the gold standard treatment for gallstone disease. However, despite being a minimal invasive technique the commonest complaint following laparoscopic cholecystectomy is still post operative pain. Pain after laparoscopic cholecystectomy is multifactorial and pneumoperitoneum pressure is thought to be one of the reasons. This study was planned to evaluate the post operative shoulder pain after laparoscopic cholecystectomy using low (10mm Hg) and standard pressure (14 mm Hg) Pneumoperitoneum. Material & Method: A prospective randomized study was done in 100 ASA grades I and II patients of cholelithiasis in MGM Medical College and hospital, Aurangabad, India. The patients were divided into two groups-Group A patients undergoing laparoscopic cholecystectomy with low pressure (10 mm) and group B patients with standard pressure (14 mm). The intensity of shoulder pain was measured by VAS score and the results in both the groups were compared in terms of pain frequency, intensity, post operative analgesic requirement and hospital stay. Statistical Analysis: Demographic data and intraoperative complications were analyzed using chi-square test. Frequency of pain, intensity of pain and analgesic consumption was compared by applying ANOVA test. Results: Four patients of group A with low pressure (10mm) had shoulder tip pain and required rescue analgesia compared to 16 patients in group B with standard pressure. The intensity of pain was statistically significant with mean VAS score of 0.08 in low pressure and 1.00 in standard pressure group (p-value 0.045). There was more analgesic consumption in the post operative period in the standard pressure group. The operating time and complications were similar in both the groups. Conclusion: Laparoscopic cholecystectomy done under low pressure pneumoperitoneum significantly decreases the intensity and frequency of post-operative shoulder tip pain. It also decreases the demand for post operative analgesia, hospital stay and hence-forth early recovery and better outcome. 1 Volume 2017; Issue 12 J Surg, an open access journal ISSN: 2575-9760 Citation: Singh R, Suryawanshi PR, Singh K (2017) A Prospective Randomized Clinical Study of Comparing Low Pneumoperitoneum Pressure Versus Standard Pressure for Reduction of Shoulder Tip Pain in Laparoscopic Cholecystectomy.

Attitudinal Factors Associated with Prostate Cancer among Adult Males in South Eastern Nigeria

Prostate cancer is one of the most common and lethal cancers in the world. The incidence of prostate cancer has been increasing in recent years. Beliefs and awareness towards prostate cancer screening among men is very crucial for early detection and management of the condition. In Nigeria, it is the most common male cancer and maybe as high as that seen in African Americans in the united states. This paper examines the knowledge, belief and attitudes of men in Nigeria towards prostate cancer and prostate cancer screening for the peaceful existence in our society .
Nutrient uptake in ‘Venus’ grape vine grafted onto different rootstocks during two growing seasons

The current study aimed to assess the influence of the ‘IAC 766’, ‘IAC 572’, ‘IAC 313’ and ‘IAC 571-6’ rootstocks on nutrient uptake of ‘Venus’ grape vine by pruning branches and harvesting clusters during two consecutive grape growing seasons. The experiment was conducted in Votuporanga, state of Sao Paulo. Treatments consisted of the variety ‘Venus’ grafted onto four rootstocks during two growing seasons (2013 and 2014). The rootstocks evaluated were ‘IAC 766’, ‘IAC 572’, ‘IAC 313’ and ‘IAC 571-6’. We sampled the grape branches at pruning and their clusters at harvest time. The macro and micronutrient contents in both branches and clusters were analyzed. Nutrient uptake and removal were separately estimated in pruned branches and harvested clusters by uptake nutrient sum. Results indicated great nutrient uptake means in ‘IAC 572’ and ‘IAC 766’ during both seasons. Moreover, total removal uptake showed the following order K > N > Ca > P > Mg > S > Mn > Fe > Zn > B > Cu in pruned branches and harvested clusters.
Effect of Seed Vigour and Pretreatment on Germinability and Seedling Growth of Safflower under Drought and Salinity Conditions

The present research was carried out to investigate the effects of the seed vigour and pretreatment and osmotic and salt stresses on safflower seed germination and seedling development. For this purpose, a factorial experiment was conducted based on randomized complete block (RCB) design with three replications. The experimental treatments was also included in two levels of seed vigour, five levels of salinity and osmotic stresses and three levels of seed pretreatment. Our results showed that increasing seed deterioration level, salinity and osmotic strengths, had inhibitory effects on seed viability and germinability, germination speed, vigor index and seedling dry weight and length. Pretreatments increased percentage and speed of germination, vigour index and seedling length. Increasing the deterioration of seeds, and also the strengths of salt and osmotic stresses, were led to decrease of chlorophylls a and b content in safflower seedlings, while pretreatment improved chlorophylls a and b content of seedlings.
A nalysis of L aw R eview Strategic Non-Entry

Este artigo traz uma ideia simples e uma recomendação clara de política pública. A ideia é que uma empresa produtora num dado mercado geográfico ou mercado de produto A pode preferir não entrar noutro mercado geográfico ou de produto B para mais tarde adquirir o detentor do monopólio em B sem qualquer objeção da autoridade antitruste ou de concorrência competente por B – prejudicando assim os consumidores em B. Apresentamos fatos estilizados para este comportamento de não-entrada seguido de posterior entrada por aquisição e construímos um modelo teórico de jogo compatível com tais evidências. Nosso modelo estende o modelo clássico de entrada destacando a rationale para o comportamento observado. A implicação direta para política pública é que as autoridades de concorrência ou antitruste devem prestar mais atenção às fusões e aquisições propostas onde o poder de mercado só muda de mãos. A possibilidade de bloquear essas fusões – se não for demonstrado ganho de eficiência em comparação com a chamada entrada por construção ou entrada clássica – deve ser seriamente considerada, como sugere um arcabouço mais dinâmico como o nosso. ABSTRACT
Two compact H ii regions at the remote outskirts of the Magellanic Clouds

Aims. The Hii regions LMC N191 and SMC N77 are among the outermost massive star-forming regions in the Magellanic Clouds. So far, few works have dealt with these objects despite their interesting characteristics. We aim at studying various physical properties of these objects regarding their morphology (in the optical and Spitzer IRAC wavelengths), ionized gas emission, nebular chemical abundances, exciting sources, stellar content, age, presence or absence of young stellar objects, etc. Methods. This study is based mainly on optical ESO NTT observations, both imaging and spectroscopy, coupled with other archive data, notably Spitzer images (IRAC 3.6, 4.5, 5.8, and 8.0 μm) and 2MASS observations. Results. We show the presence of two compact Hii regions, a low-excitation blob (LEB) named LMC N191A and a high-excitation blob (HEB) named SMC N77A, and study their properties and those of their exciting massive stars as far as spectral type and mass are concerned. We also analyze the environmental stellar populations and determine their evolutionary stages. Based on Spitzer IRAC data, we characterize the YSO candidates detected in the direction of these regions. Massive star formation is going on in these young
Characterizing Near-Surface Fractured-Rock Aquifers: Insights Provided by the Numerical Analysis of Electrical Resistivity Experiments

Fractured-rock aquifers represent an important part of the groundwater that is used for domestic, agricultural, and industrial purposes. In these natural systems, the presence and properties of fractures control both the quantity and quality of water extracted, meaning that knowledge about the fractures is critical for effective water resource management. Here, we explore through numerical modeling whether electrical resistivity (ER) geophysical measurements, acquired from the Earth’s surface, may potentially be used to identify and provide information about shallow bedrock fractures. To this end, we conduct a systematic numerical modeling study whereby we evaluate the effect of a single buried fracture on ER-profiling data, examining how the corresponding anomaly changes as a function of the fracture and domain characteristics. Two standard electrode configurations, the Wenner-Schlumberger (WS) and dipole-dipole (DD) arrays, are considered in our analysis, with three different spacing factors. Depending on the considered electrode array, we find that the fracture dip angle and length will impact the resistivity anomaly curves differently, with the WS array being better adapted for distinguishing between sub-horizontal and sub-vertical fractures, but the DD array leading to larger overall anomaly magnitudes. We also find that, unsurprisingly, the magnitude of the resistivity anomaly, and thus fracture detectability, is strongly affected by the depth of overburden and its electrical resistivity, as well as the fracture aperture and contrast between the fracture and bedrock resistivities. Further research into the electrical properties of fractures, both above and below the water table, is deemed necessary.
Emotional Intelligence and Gender as Predictors of Academic Achievement among Some University Students in Barbados

This study investigated emotional intelligence (attending to emotion, positive expressivity and negative expressivity) and gender as predictors of academic achievement among 163 undergraduate psychology students in The University of the West Indies (UWI), Cave Hill Campus, Barbados . Results revealed significant positive and negative correlations among academic achievement, emotional intelligence components and gender. Additionally, using the stepwise multiple regression analysis, it was found that emotional intelligence contributed 40% (Rsq= 0.396) to the variance in academic achievement while simple regression analysis revealed that gender also contributed 5% (Rsq =0.048) to academic achievement and these results were significant indicating that both emotional intelligence and gender predicted academic achievement but emotional intelligence was a better predictor of academic achievement than gender. The Independent t-test analysis also revealed gender disparity in academic achievement and attending to emotions in favour of girls. These findings were discussed in the paper.
Inactivation of Francisella tularensis Utah-112 on food and food contact surfaces by ultraviolet light.

Francisella tularensis is the causative agent of tularemia, a plague-like illness that affects animals and humans, and has caused large illness pandemics in the last century. It has also been used as a biological warfare agent, and tularemia can be contracted through consumption of contaminated food and water. In this study the use of a U.S. Food and Drug Administration approved technology, 254 nm ultraviolet light (UV-C), to inactivate F. tularensis Utah-112 (a rodent pathogen) on food and food contact surfaces was investigated. The D10 value, the UV-C dose needed to inactivate one log of microorganism, was approximately 0.71 mJ/cm2 on agar plates using a low UV-C intensity of 100μW/cm2/s. When a commercial UV-C conveyor was used (5 mW/cm2/s) 0.5 J/cm2 inactivated >7 log CFU of F. tularensis Utah 121 on agar plates. At 0.5 J/cm2 UV-C inactivated >4 log CFU of Utah-112 in beef, chicken, catfish, frankfurter, and bratwurst exudates inoculated onto stainless steel coupons, and >7 log CFU was eliminated at 1 J/cm2 UV-C. Similar results were obtained when the exudates were inoculated onto high density polypropylene. Approximately 0.5 log CFU was inactivated on chicken breast, beef steak, and catfish fillets, and approximately 1.9 log CFU on frankfurters and bratwurst at a UV-C dose of 1 J/cm2. These results indicate routine use of UV-C during food processing would provide workers and consumers some protection against F. tularensis.
Labor Unrest and Incipient Collective Bargaining in China

ABSTRACT In this paper, we argue that both labor unrest and collective bargaining are increasing in China. Using McAdam's political process theory, we argue that Chinese workers are striking more and offensively in support of their economic demands. We identify the state's interests in promoting collective bargaining, and through an analysis of union and employers’ organizations, attempt to predict the future trajectory of collective bargaining in China. Using new data about strikes, we confirm our argument that strikes in China are increasing. Based on very limited past and current research, we create a taxonomy of baseline collective bargaining in China against which future developments can be compared.
Using Scaling Methods to Improve Support Vector Regression’s Performance for Travel Time and Volume Predictions

Long queues often happen on toll roads, especially at the tollgates. These create many problems, including having an impact on the regular roads nearby. If travel time and traﬃc volume at the tollgates can be predicted accurately in advance, this would allow traﬃc authorities to take appropriate measures to improve traﬃc ﬂow and the safety of road users. This paper describes a novel combination of scaling methods with Support Vector Machines for Regression (SVR) for travel time and tollgate volume prediction tasks, as part of the Knowledge Discovery and Data Mining (KDD) Cup 2017. A new method is introduced to handle missing data by utilising the structure of the road network. Moreover, experiments with reduced data were conducted to evaluate whether conclusions from combining scaling methods with SVR could be generalised.
Silk cotton cake as an alternate protein source in the diet of tiger shrimp, Penaeus monodon Fabricius 1798, and its effects on growth, nitrogen utilisation and metabolism

Silk cotton cake (SCC) was incorporated in the practical diets of tiger shrimp, Penaeus monodon at 5 different levels (0, 2.5, 5.0, 7.5 and 10.0%) by replacing fish meal. Growth cum digestibility study was conducted for 45 d in 500 l experimental tanks using shrimps weighing 2.09 ± 0.06 g with three replications for each treatment. There was significant (p<0.05) reduction in specific growth rate (SGR) and daily growth coefficient (DGC) in shrimps fed diets having more than 2.5% SCC compared to other treatments. Apparent crude protein, lysine and methionine digestibilities decreased (p<0.05) in shrimp fed with more than 2.5% SCC incorporation. The free amino acid profiles of shrimp muscle at 4 h post-feeding indicated significantly (p<0.05) lower levels for lysine and methionine in shrimp fed with higher levels of SCC. Post-prandial ammonia nitrogen excretion (PPANE) on hourly basis revealed that incorporation of SCC has greatly influenced the N excretion. SCC incorporation has not affected the haemolymph protein concentration up to 7.5% and the haemocyanin content up to 5% inclusion. The experimental results indicate that SCC can be incorporated up to 2.5% in the diet of black tiger shrimp P. monodon .
Determination of Concentrations of Natural Radionuclides in Soils and Water in Non-cultivated Sites in Seberang Perai, Malaysia

The purpose of this study is to evaluate the level of concentration of radionuclides in Non-cultivated soils and water, which are taken from Seberang Perai in Penang, Malaysia. The concentrations of natural radioactive nuclides; 226 Ra, 232 Th, and 40 K were assessed using HPGe detector. The concentrations of 226 Ra, 232 Th, and 40 K in soil samples are 4.98 to 160.09, 3.43 to 233.59 and from 56.40 to 819.63 Bq kg -1 respectively. The mean concentrations of 226 Ra, 232 Th, and 40 K are 36.00, 44.21 and 254.60 Bq kg -1 respectively. Similarly, the concentrations of 226 Ra, 232 Th, and 40 K in water samples were assessed to be from 0.19 to 2.13 (mean=1.07), 1.15 to 4.32 (mean = 3.08 ) and from 92.37 to 172.43 (mean = 132.43)Bq l -1 respectively. The outcomes using Pearson’s correlation shows that the relationship of concentrations of 226 Ra, 232 Th and 40 K amongst soil and water for the researched samples are R=0.85, R=0.91 and R= 0.75 correspondingly with p< 0.05. Statistical analysis using T-test showed significant distinction between concentrations of 226 Ra, 232 Th and 40 K in soil and water with t values equal to 3.92, 3.12, and 2.57 respectively at p < 0.05. The results clearly show the values of concentrations of these radionuclides are at the allowable levels with corresponding with dose assessment and radiological indexes.
Gender Inequality in New Media: Evidence from Wikipedia

Media is considered to be critical for gender equality. I analyze Wikipedia, one of the prominent examples of new media. I study why women are less likely to contribute to Wikipedia, the implications of the gender gap, and what can be done about it. I find that: (1) gender differences in the frequency of Wikipedia use and in beliefs about one's competence explain a large share of the gender gap in Wikipedia writing; (2) the gender gap among contributors leads to unequal coverage of topics; (3) providing information about gender inequality has a large effect on contributions.
Validation of satellite-based soil moisture retrievals from SMAP with in situ observation in the Simineh-Zarrineh (Bokan) Catchment, NW of Iran

Soil moisture is an influential parameter in land surface hydrology and precise soil moisture data that can help researcher to realize the climate changes and land-atmosphere interactions. A initial struggle for the utilize of soil moisture data from satellite sensors is their reliability. It is important to appraise the dependability of those data before they can be regularly used at a global or local scale. In this study, the satellite soil moisture data was evaluated from the Soil Moisture Active/Passive (SMAP) over Simineh-Zarrineh Catchment in Bokan region, NW of Iran. A total of 287 soil samples as ground-based observations in the time period of 03 April to 03 December 2017 were taken for SMAP data validation. Results showed that the satellite data and in situ observation has a good correlation, with a mean correlation (r) value of 0.63 in total. This correlation level showed that , commonly, the SMAP soil moisture products over Simineh-Zarrineh Catchment (Bokan) have great quality, and it would be valuable for versatile utilization, including monitoring of land surface, weather prediction, modeling of hydrological process, soil loess monitoring, and climate studies. The results reveal that the remotely sensed data demonstrate the good correlation with in situ observation across the dry land with mean correlation (r) values of 0.67 throughout the time period. Particularly, SMAP soil moisture reveal a constant structure for obtain the spatial distribution of surface soil moisture. Additional researches are necessary for well realizing the SMAP data.
