DFT Studies on Substituent Effects in Palladium-Catalyzed Olefin Polymerization

Gradient-corrected density functional theory has been used to study substituents effects on the cationic N∧N−Pd(II) diimine catalyst in ethene and propene polymerization. Here N∧N = −C(R)−N(Ar)−N(Ar)−C(R)− with R = H, −CH3, −An and Ar = H, C6H5, −2,6-C6H3(Me)2, −2,6-C6H3(iPr)2. Calculations have been performed on the [N∧N-Pd(II)−P]+ (P = n-propyl and isopropyl) alkyl complexes (1) and the corresponding [N∧N-Pd(II)−P(η2-CH2CHRo)]+ π-complexes of ethene (Ro = H) and propene (Ro = CH3), as well as the ethene and propene (1,2- and 2,1-) insertion transition states. The results show that an increase in the size of the substituents on the Pd(II) catalyst enhances the preference of 1 for the isomer with the branched isopropyl alkyl group P, while for the olefin complexes [N∧N-Pd(II)−P(η2-CH2CHRo)]+ the isomer with the linear n-propyl group P becomes preferred. Further, an increase in the size of the substituents affects the relative binding of ethene and propene. Thus, the electronic preference of propene comple.
Vascularization of Human Embryonic Stem Cell-derived Cardiac Tissues

Cardiovascular diseases can leave permanent lesions and cardiac repercussions, especially concerning extensive cardiomyocyte death and regression of coronary microvasculature, as a result of heart failure, myocardial infarction or ischemia/reperfusion episodes. In the past few decades, several approaches aiming to restore the native function in damaged hearts have been attempted, including through the generation of tissue-engineered cardiac constructs that are intended to repopulate the injured cardiac muscle with a new group of contractile cells. However, the major limitation to these constructs has been their inadequate vascularization and reperfusion in vitro that highly limits their long-term efficacy and viability, particularly in thick and complex tissueconstructs. Moreover, the paracrine cross-talk between endothelial cells and cardiomyocytes also plays a critical role in improving tissue functionality, which can further promote the tissue-engineered construct survival. In the present work, a fluidic device able to support the co-culture between cardiomyocytes, entrapped in a fibrin matrix, and endothelial cells, both derived from human sources, was successfully established. In this currently optimized fluidic device, it was possible to generate several human beating cardiac constructs with endothelial cells co-presented in their networks, establishing significant ground work for further formation of a vascular system throughout the entire construct. Key-words: Vascularization, Tissue Engineering, Cardiomyocytes, Endothelial Cells, Organ-on-a-Chip, Co-culture.
Liquidity , Credit risk and Corporate Bond Spreads

This paper investigates the interaction between liquidity and credit risk based on a large transaction data set from July, 2006 to June, 2016, including the monthly data of 3716 bonds in China's bond market. In this paper, we examine the impact of the interaction between liquidity and credit risk on the non-default spread from different liquidity dimensions of market liquidity and macro factors. We find that the non-default spread is significantly related to the interaction between liquidity and credit risk. Moreover, we study the timing characteristics of the interaction between liquidity and credit risk, and show that the interaction between liquidity and credit risk has greater impact on the spreads during the financial crisis. Finally, our findings contribute to bond risk hedging.

The Transnational Dimension of Innovation in China

Advances in Chinese innovative capacity are characterized by two major features: (1) Chinese high-tech industries remain highly dependent on transfers from foreign MNCs, while the majority of China’s high-tech exports are still brought about by foreign firms. (2) The innovative capabilities of Chinese provinces are increasingly diverging, with some developing extremely fast and others not advancing at all. While the widely used national innovation system (NIS) approach is well-suited to analysing large-scale, national level policies and programmes, the Chinese case necessitates a complementary perspective that includes the transnational and the regional dimensions of technological innovativeness. Therefore, this paper reviews recent approaches in the study of technological development that focus on innovation in its regional and transnational contexts. It addresses the intersections in the analysis of transnational R&D and regional innovation systems (RIS). And it stresses the role of public policy and regional context in promoting innovative capabilities.
ANTIBIOTIC SUSCEPTIBILITY OF STAPHYLOCOCCUS AUREUS STRAINS ISOLATED FROM BLOODSTREAM INFECTIONS

Bloodstream infections (BSI) have high morbidity and mortality rates. Staphylococcus aureus is one of the two most common causes of BSI. Methicillin resistance has been increased in S.aureus strains. In this study, antimicrobial susceptibility patterns of S.aureus isolated from BSI has been evaluated. Blood cultures were performed with automated system. Th e isolates were identified as S.aureus by conventional methods and antimicrobial susceptibility were determined by Kirby–Bauer disc diff usion method according to the criteria of Clinical Laboratory Standarts Institute Of the 274 S.aureus strains, 132 (48.2%) were MRSA (methicillin resistant S.aureus) and 142 (51.8%) were MSSA (methicillin susceptible S.aureus). MRSA strains showed resistance to multiple antibiotics. Th e susceptibility rates of vancomycin, gentamycin, erythromycin, tetracycline and ciprofl oxacin in methicillin resistant strains (MRSA) were 100%, 13%, 12%, 10% and 9%, respectively. In the methicillin susceptible group; susceptibility rates of vancomycin, gentamycin, tetracycline ciprofloxacin and erythromycin, were 100%, 97%, 94 %, 93 % and 91 %, respectively. Th e incidence of methicillin-resistant S.aureus was 25.7% in 2003 and increased to 67.8% in 2006 (For 2004, 2005 and 2006 were 36.7%, 42.2% and 67.8%, respectively) but decreased to 57.1% in 2007 In every region; antimicrobial susceptibility profile and colonisation rate of S.aureus strains should be provided for better management of the BSI and to develop rational strategies for public health policies.
Quantitative XPS analysis of bimetallic Cu-Co catalysts

The surfaces of bimetallic Cu-Co/SiO 2 catalyst with 1 Cu:2 Co atomic ratio has been studied focusing on the determination of bimetallic phase thickness and its distribution using a mathematical formalism from X-ray photoelectron spectroscopy (XPS) intensities. X-ray diffraction analysis indicated a Cu-Co alloy formation and XPS qualitative analysis showed that Cu 0 and Co 0 species were present on the surface. Atomic ratios of Cu/Si, Co/Si and Co/Cu from XPS and atomic absorption (A.A.) analyses suggested homogeneous particle formation with a slight Cu surface enrichment in the catalyst. A mathematical model was proposed from relative intensity ratios, which was able to determine the metallic particle thickness and its coverage fraction at the support. Considering that these values were comparable to those for the particle size obtained from transmission electron microscopy (TEM) measurements, it may be said that the model describes the evaluated system accurately.
Theoretical Calculation of Crystal Cohesive Energy of (ZrTi)B2 Solid-Solutions

The two kinds of the Ti-rich (Ti0.8Zr0.2)B2 and Zr-rich (Zr0.8Ti0.2)B2 permutation solid solutions were formed when hot pressed ZrB2 and TiB2 ceramics. On the base of the empirical electron theory (EET) of solids and molecules, the crystal bond energy of the two solid-solutions was calculated by use of Average Atom Model, Average Cell Model and Real Cell Model. In Real Cell Model, the crystal cell parameters were assumed to be unchanged and changed. The calculation results were compared among the three models. The results showed that the general trend about the deviation electrons of B element is consistent except Real Cell Model when the lattice constant is unchanged. Namely, the number of the deviation electrons in TiB2 is more than that in ZrB2.The maximum error of crystal bond energy calculated by the three models is 38KJ/mol and the relative error is less than 2%. The general trend of the crystal bond energy calculated by the three models is monotonically increased similar to the trend of melting point of these materials. Relatively speaking, the calculation of crystal bond energy calculated by Average Atom Cell Model is simpler and more reasonable.
The Phase Separation Capabilities of Two T-Junctions Placed in Series

The phase split that occurs almost inevitably at a T-junction can be utilized to effect partial phase separation. Previous experimental investigations have been confined to considering individual T-junctions. This paper considers the performance of a separating system consisting of two large diameter (0.127 m) T-junctions, and how the geometry of the system can be altered and the effects this has on the separation performance. Experiments monitored the separation capabilities of each junction, thus allowing the phase separation capabilities of different outlet combinations to be compared. Experiments were performed in both the semi-annular and stratified flow patterns at ambient temperature and pressure.
Cereal Fiber and Health: Current Knowledge

The average American consumes only half of the recommended daily intake of fiber, and despite dietary guidance to increase intake, fiber consumption has not increased. Thus, additional consumer choices and consumer-oriented messaging on the sources and benefits of fiber is warranted. Fiber, in particular cereal fiber, is associated with protection against development of gastrointestinal disorders such as constipation, as well as weight gain, cardiovascular disease, type 2 diabetes, and total mortality. Fiber in cereal grains is primarily located in the bran: wheat bran is 4 times higher in fiber than whole grain wheat and more than 10 times higher in fiber than white wheat flour. Cereal fiber and bran contain fewer calories than whole grains or white flour, and bran is a concentrated source of other bioactive compounds that may contribute to many of the health benefits associated with cereal fiber and whole grains. Formulating foods with cereal fiber and bran would provide consumers with more choices for .

Analysis of reliability for fault tolerant design in NANO CMOS logic circuit

The emerging nano scaled electronic devices are Carbon Nanotubes (CNT), Silicon nanowires (SINW), nano CMOS switches etc. In Nano CMOS switches, the devices can be interconnected to build the nano scaled CMOS circuit. In this nano CMOS circuit, faults occur at three levels, such as gate level, circuit level and switch level. This paper focusses on the switch level faults of stuck-open or stuck-off and stuck-short or stuck-on that frequently occurs in CMOS switches. To overcome the switch level faults and to increase the reliability, the fault tolerant technique known as the Quadded Transistor (QT) structure is used. An analytical model has been formulated to determine the probability of failure by analyzing the stuck open and stuck short faults. Also, the model has been formulated by implementing QT structure for the single CMOS NAND2 gate. By the use of analytical formulations, the results has been simulated for the occurrence of minimum to maximum number of defective transistors in CMOS logic circuit.
Acute and sub-acute toxicity of the aqueous extract of the stem bark of Rauwolfia vomitoria (Apocynaceae) in Wistar rats.

The present study investigated the toxicological potential of the oral administration of the stem bark aqueous extract of R. vomitoria on the liver and kidney in rats. Acute oral toxicity study of the extract to a single dose of 2000 mg/kg was studied in 10 rats of both sexes. Sub –acute oral toxicity of aqueous extract of was carried out on 60 rats. We constituted 4 groups of 10 rats each (5 males and 5 females) which were orally administered 300, 600, and 900 mg/kg of aqueous extract and control group received water. 2 group satellites (SAT) of 10 rats each (5 males and 5 females) in which one group (SAT 900 mg/kg) was received orally 900 mg/kg of aqueous extract and another (SAT control) water. Serum blood was collected for biochemical and haematological parameters. The liver and kidney served for histological examination. No deaths of acute oral toxicity were recorded. In female rats, Aspartate Aminotransferase (ASAT) activity increased by 31.20 % and Alamine Aminotransferase (ALAT) increased by 37.20 %. In male rats, only ALAT activity increased significantly by 35.37 % compared to control. Haematological analysis revealed in male rats treated at the dose of 900 mg/kg an increase significant (p<0.001) level of white blood cells with 52.20 %, compared to control group. Histological examination of liver and kidney showed normal architecture. Aqueous extract has untoward effect on liver and kidney, could be considered non-toxic.

Dipartimento di Promozione Della Salute, Materno-Infantile, Medicina Interna e Specialistica di Eccellenza “G. D’Alessandro” (PROMISE), Sezione di Malattie Endocrine, del Ricambio e della Nutrizione, Università di Palermo, Palermo, Italy Purpose: To evaluate circulating irisin levels in patients with active and controlled Cushing’s disease (CD). Design: Forty-four patients with CD evaluated during the active phase and after 12 months of biochemical remission and 40 controls were recruited. Methods: Phenotypic, anthropometric, hormonal and metabolic parameters, including insulin sensitivity estimation by homeostatic model of insulin resistance, Matsuda index and oral disposition index and circulating irisin levels were evaluated. Results: Patients with active CD showed lower irisin levels compared to controls (p<0.001) and controlled CD (p<0.001). The independent variables significantly associated with irisin were waist circumference (WC) (p=0.025), body fat percentage (BF%) (p=0.009), PTH (p=0.007) and chair rising test (CRT) (p<0.001) in active CD and WC (p=0.013), BF% (p=0.014), PTH (p=0.038), CRT (p=0.029) and urinary-free cortisol (p<0.001) in controlled CD. Conclusion: Circulating irisin levels tend to be lower in patients with active CD compared to those with controlled CD and controls. They are strongly associated with osteosarcopenia and central obesity in CD and therefore may be a possible marker of diagnosis.
The Work-Related Stress among Members of Integrated Rescue Service and Influence of this Stress to Couple Relationship

Integrated rescue system members (firefighters, police officers, and rescue workers) are affected by specific stress factors for example: intercourse with death and human suffering, health damage, or feelings of helplessness [1]. Their work is usually psychologically, physically and emotionally demanding and they must work in shifts [2]. It can affect couples and family relationships. A working stress can be transferred to family members. Fallowing this, as more than 50% of marriage end with divorce, it is particularly important to determine how much the performance in profession can affect family stability [3]. Unfortunately, not only in the Czech Republic, the issue of the partner life of IZS members has been given very little attention [1]. However, with regards to occupational health and life-safety workloads and increased work-related stress, it would be advisable to prepare IRS members and their partners for this situation [4]. Using effective coping strategies, it could have a considerable positive impact on partners’ life, but also on the work performance of both partners as well [2]. Of course there are also positive impacts on the whole society, because society needs this professions and its members.
Heterosis and combining ability studies in rice hybrids (Oryza sativa L.) with an emphasis to gall midge resistance

The aim of this study was to develop rice hybrids with resistance to gall midge and make inferences regarding components of heterosis in hybrids obtained by crossing six lines and seven testers in Line X Tester mating design. General combining ability (GCA) of parents (six lines and seven testers) and specific combining ability (SCA) and heterosis among 42 hybrids for gall midge resistance, yield and its related traits were analyzed. The magnitude of SCA variances was higher than GCA variance for all the traits except panicle length and thousand-grain weight, where the GCA variance was higher. Among the lines, JMS 21A was found to be a good general combiner for spikelet fertility, number of grains per panicle, grain yield per plant and gall midge incidence. Among the testers, JR 67 recorded high grain yield per plant along with favorable GCA for the number of grains per panicle, grain yield per plant and gall midge incidence. Most of the hybrids recorded positive significant standard heterosis for grain yield per plant. Hybrid JMS 19A X JR 80 recorded significantly positive SCA effect and highest relative heterosis, heterobeltiosis and standard heterosis over checks for grain yield per plant along with moderate resistance to gall midge. The alleles that control resistance to gall midge resistance have a degree of dominance more than 1, which indicates a favorable situation for obtaining resistant hybrids.
A Study on Impact of Internal Mobility on Organisational Performance: A Case of Automotive Axles Pvt Ltd, Mysuru

-Over a time, manufacturing Industry in India is essentially an outstanding amongst the most well-known enterprises in Indian market. Manufacturing is the producing of goods and a service using labor and other machinery tools this helps to understand the organization performance directly or indirectly has an impact on internal mobility of an employee. Internal mobility mainly tells that relying upon worker's expertise skill and prerequisites with the toss of the employment with organizational commitment and the change in job structure, job design occurs with or without raise in the salary. Organization performance which has many factors which influence the performance but internal mobility is also a supporting factor which has an impact in achieving the vision of the company. This gives an understanding that apart from providing all the necessary facility and good working culture, healthy promotion and transfer employee exit rates are increasing. Thus, internal mobility is most preferable objective to success which implies observable career accomplishments such as promotion, transfer & hierarchical level held and salary. In future to achieve internal mobility, company should adapt the principle of succession management at all ranks, provide transparent discussion of skill and the potential, as well as organizational needs. The reason for this would the favoritism and lack of recognition which is making an employee dissatisfaction towards their organization by this I conclude that the unfair or unethical practices in organization with respect to the internal mobility in the future periods make employee unhappy this is one of the reason to leave an organization which creates a huge impact in the organization performance
Finding Mr. Schumpeter: An Empirical Study of Competition and Technology Adoption∗

We estimate the effect of competition on the adoption of a cost-reducing technology in the cement industry, using data that span 1953-2013. The new technology, the precalciner kiln, reduces fuel usage and hence fuel costs. We find adoption is more likely if the fuel cost savings are large, and less likely if there are many nearby competitors. We also find that competition damps the positive effect of cost savings. The results are consistent with a dynamic theoretical model in which competition can deprive firms of the scale necessary to recoup sunk adoption costs.
Expressive density models for high energy physics using a custom latent space

Testing the compatibility between experimental observations and hypotheses about nature is the heart of the scientific method. This often requires us to model the probability density of possible observations, which is a challenging analytic task when data are multi-dimensional. We show that density models describing multiple observables with (i) hard boundaries and (ii) dependence on external parameters may be created using an auto-regressive Gaussian mixture model. The model is made more expressive using a novel method in which data are projected onto a custom latent space. The method is demonstrated on particle physics data sensitive to anomalies in the electroweak production of a Z boson in association with a dijet system. Such an approach may be applied to similar problems within other fields.
