Copper Delafossites under High Pressure—A Brief Review of XRD and Raman Spectroscopic Studies

Delafossites, with a unique combination of electrical conductivity and optical transparency constitute an important class of materials with their wide range of applications in different fields. In this article, we review the high pressure studies on copper based semiconducting delafossites with special emphasis on their structural and vibrational properties by synchrotron based powder X-ray diffraction and Raman spectroscopic measurements. Though all the investigated compounds undergo pressure induced structural phase transition, the structure of high pressure phase has been reported only for CuFeO2. Based on X-ray diffraction data, one of the common features observed in all the studied compounds is the anisotropic compression of cell parameters in ambient rhombohedral structure. Ambient pressure bulk modulus obtained by fitting the pressure volume data lies between 135 to 200 GPa. Two allowed Raman mode frequencies Eg and A1g are observed in all the compounds in ambient phase with splitting of Eg mode at the transition except for CuCrO2 where along with splitting of Eg mode, A1g mode disappears and a strong mode appears which softens with pressure. Observed transition pressure scales exponentially with radii of trivalent cation being lowest for CuLaO2 and highest for CuAlO2. The present review will help materials researchers to have an overview of the subject and reviewed results are relevant for fundamental science as well as possessing potential technological applications in synthesis of new materials with tailored physical properties.
The effects of low-dose aspirin treatment in ovarian and uterine responsiveness implantation and pregnancy rates in patients undergoing ICSI.

Vascularization of the follicle may play a role in its maturation and aspirin seems to increase this vascularization.In this investigation we have studied the effects of low-dose aspirin on ovarian and uterine response, implantation and pregnancy rates in patients undergoing intracytoplasmic sperm injection (ICSI). This prospective semirandomized, double-blind, placebo-controlled study was undertaken in Mirza Kochek Khan IVF center. Forty four infertile patients who were undergoing ICSI cycle were studied and they were divided in two groups. The mean age of patients and distribution of the cause of infertility in two groups were similar. In the treatment group, 22 patients underwent controlled ovarian hyperstimulation and received a daily dose of 100 mg aspirin. In the control group 22 patients underwent controlled ovarian hyperstimulation in association with placebo. Number of follicles ≥ 15mm in diameter, number of oocytes retrieved, endometrial thickness, cancellation rate, number of transferred embryos and implantation and pregnancy rates were analyzed in two groups.There was no statistically significant difference between the treatment and control groups for each of the above variables (P >0.05). This study showed that low dose aspirin therapy has no added effect to ovarian and uterine response, implantation and pregnancy rates in ICSI patients.Further studies are recommended for confirmation of our results.
Phototransferred Thermoluminescence from Obsidian Using Ultraviolet Radiation

The behavior of TL and PTTL under UV stimulation in gamma-irradiated obsidian was investigated. The noticeable change of the shape of the main TL peak after thermal or optical stimulation clearly shows that this peak is related to at least two traps. The PTTL curves recorded after preheating up to a given increased end temperatures are described by two processes. The first one is associated to the decay of the traps responsible for the main TL peak. The second is related with the phototransfer from the deep to the main trap. Fading studies over a period of 14 days show that the PTTL faded by 5% when exposed to 50Gy.The results further predict the potential of obsidian as a phosphor in TL dating, accident and industrial dosimetry. Keywords: Obsidian, Phototransfer, Phosphor, Fading.

Choice of Product Architecture, Product Quality, and Intra-Firm Coordination: Theory and Evidence Choice of Product Architecture, Product Quality, and Intra-Firm Coordination: Theory and Evidence

Coordination within organizations has been recognized as an issue of central importance in the organizational economics literature, where the degree of interdependence between individuals’ actions is taken as given. In reality, however, the degree of interdependence is affected by the choice of an organization’s strategy, and hence there are inter-relationships among the interdependence of individuals’ actions within organizations, their ability to coordinate their actions, and the choice of the organization’s strategy. We explore these inter-relationships by focusing on coordination between engineers. In our theoretical model, we consider a firm that designs and sells a product which consists of two components, 1 and 2. Engineer i (= 1, 2), who is in charge of the design of component i, attempts to maximize component i’s quality (local quality). The degree to which designs of different components interact with each other is a key determinant of success in product development. In this context, previous research on product design has found that product architecture is a useful concept. In our model, a firm can increase the product’s global quality by increasing the integrality of the product’s architecture. Higher integrality, however, also increases the degree of interaction between the two components’ designs, making coordination between engineers more important. We hypothesize that the longer the engineers work together the better they can coordinate their actions. Our model yields the following testable prediction: “As consumers’ valuation of product quality increases, the firm invests more to reduce engineers’ turnover rate. A lower turnover rate, in turn, increases the integrality of the product architecture. ” We investigate this prediction empirically by analysing data we collected through administration of questionnaire surveys to manufacturing and software companies in Japan, Korea, and China. A novelty of our questionnaire survey is that it measures the integrality of product architecture with a continuous variable ranging from 0 to 100, whereas previous studies on product architecture are based on a dichotomy of modular or integral architecture. We test our theoretical prediction by the two-stage least squares procedure, and find empirical support for our theoretical prediction in Japan and China but not in Korea. We discuss possible reasons for the lack of empirical support in Korea.
14C Ages of Bone Fractions from Armenian Prehistoric Sites

Prehistoric cultures in Armenia are still poorly known; thus, accelerator mass spectrometry (AMS) radiocarbon dates are invaluable in constructing an accurate chronology. Bone samples have been collected from sites representing the Middle Paleolithic, Chalcolithic, and Early Bronze periods. Most of the bone samples are poorly preserved. We describe the separation technique for the extraction of both the bioapatite and collagen fractions. In many cases where the bone had very low organic material content, the collagen fractions yielded a younger age, although the ages of bioapatite fractions were found to be in good agreement with associated archaeological artifacts. In cases where bone was well preserved, both fractions exhibited ages in good agreement with the artifacts. The accuracy of 14C dating of bone material always depends on its degree of preservation, and each case should be carefully evaluated to determine which fraction is less contaminated in order to accurately date a burial event.
A FRAMEWORK FOR EVALUATING IT BENEFITS IN CONSTRUCTION COMPANIES

Information Technology (IT) is seen as an enabling mechanism to allow radical change to be effected in construction industry. However, firms in the construction industry are slowly responding and adapting to developments in information and communication technologies (Love, et al., 2000). A key barrier to the more effective exploitation and application of IT in the construction sector has been the lack of investment on a scale comparable with other sectors. A primary reason cited for the low level of investment is the low level of perceived benefits from IT investments amongst construction business managers (Andresen, et al., 2000). Based on literature review and a survey in the local construction companies, this paper presents a “5Cs” evaluation framework to assist construction companies to predict, measure and evaluate the potential benefits that can or should be achieved by the introduction of IT. The proposed framework answers questions concerning about all factors that need to be considered in the evaluation, such as why, what, when, who and how to perform the evaluation. It is not only presented as a research result but also can be used as a guideline in practice.
Does workplace bullying experiences impact, on long-term, employees levels of strain?

-The present study reports the long-term effects of workplace bullying exposure on Romanian employees’ physical strain. 73 (Mage=31.5; SDage=8.91) Romanian employees participated at baseline (t1June-September 2012) and at follow-up six months later (t2. March 2013June 2013). The results of the present article showed that workplace bullying consequences are more important for the longterm than for the short one. The results showed that workplace bullying predicted at time 1 only 6.2% of physical strain’s variance while at time 2 it predicted 13.1% of physical strain’s variance. These results emphasize that the more prolonged are workplace bullying acts the more physically strain Romanian employees will feel. It seems that the negative effects of workplace bullying exposure are more salient on long-term than on short-term. The results of the present article can have practical implications because they can bring new information useful for human resources practitioners, helping them designing and conducting more efficient training programs.
Seasonal dynamics and depth distribution of Planktothrix spp. in Lake Steinsfjorden (Norway) related to environmental factors

To investigate factors and mechanisms regulating toxin-producing populations of Planktothrix, we conducted a field study (2001-04) in the mesotrophic Lake Steinsfjorden, South-eastern Norway. The occurring species, Planktothrix rubescens and P agardhii, had similar depth distributions and seasonal dynamics, both forming metalimnetic blooms in 10-14m depth. By comparing the resource availability and temperature in Lake Steinsfjorden with demands determined in laboratory studies, temperature and light were identified as the most important factors controlling growth and depth distribution of Planktothrix spp. In addition, macronutrients, especially nitrogen, may have limited growth in periods. A lowering of nutrient supplies over time could in addition to the prevailing suboptimal temperature and light conditions prevent the population of Planktothrix spp. from forming blooms. On two occasions, a major decrease in Planktothrix spp. abundance in the open water could be linked to a transport towards the banks of Lake Steinsfjorden with subsequent decomposition in the littoral zone. Our results show that the depth distribution and seasonal dynamics of Planktothrix spp. in Lake Steinsfjorden is controlled by environmental factors in a similar way as in other Nordic, Central European and North American lakes.
Conduction mechanisms in P(VDF-TrFE)/gold nanowire composites: tunnelling and thermally-activated hopping process near the percolation threshold

High-aspect ratio gold nanowires were dispersed in a P(VDF-TrFE) matrix to form conducting polymer composites. The composites were found to follow a percolation law, with a low percolation threshold of 2.2%vol and attaining a conductivity value of 100 S m−1. The temperature and frequency dependence of the composites were studied using broadband dielectric spectroscopy. Tunnelling was found to be the main charge transport mechanism at temperatures below −100 °C and a thermally-activated hopping mechanism was determined to be responsible for conduction at temperatures above −100 °C. The correlated barrier hopping model was found to be the best fit to explain the conduction mechanisms in the composites.
Balance de nitrógeno, emisión de amonio y olores de cerdos alimentados con dietas bajas en proteína

The effect of reducing the crude protein (CP) levels in diets fed to growing pigs, was evaluated in two experiments,each using two diets formulated to contain either a normal (19%) or a reduced CP level (14%), with constantlevels for standardized ileal digestible lysine (0.85%), and metabolizable energy (3.37 Mcal ME/kg). Exp Imeasured the N balance of pigs (n= 24) initially weighing 17.7±1.29 kg, while Exp II used 24 pigs from 17.9±0.76kg to assess aerial ammonia (NH3) emissions and odor levels in dynamic airflow chambers for 21 d. InExperiment I, N intake (26.6 %), urinary N (56 %), and total N excretion (41 %) were lower (P 0.4). In Experiment II, reducing dietary CP did not affect(P>0.10) growth performance, but tended to reduce (P<0.10) manure pH (6.71, normal and 6.21±0.186 forreduced CP) and NH3 emissions, which were diminished after d-9 trial (dietary CP and days in the experimentinteracted, P<0.001). Odor levels measured on d-14 and 21 of the study, assessed by olfactometry, did not differbetween treatments (512 and 540±115.6 threshold units for the reduced and normal CP diets), but increased(P<0.01) with time on feed (440 and 612 ± 111.3 threshold units on d-14 and 21, respectively). These resultssuggest that each one percentage unit reduction in dietary CP (combined with the appropriate AA supplementation)lowers N excretion (by 8 %) and NH3 emissions from manure (by 15 %), with no effect on manure odor.
DEFATTED RICE BRAN LOW PHYTIC ACID IN THE DIET OF GRASS CARP

Com a necessidade de suplementação da alimentação da carpa capim (Ctenopharyngodon idella) com dietas artificiais, tem-se buscado ingredientes com disponibilidade regional para sua formulação. Países produtores de arroz possuem grande oferta de farelo de arroz desengordurado, porém sua utilização na alimentação de não ruminantes é limitada pela presença de ácido fítico. Assim, avaliou-se o desempenho e deposição de minerais nos ossos de juvenis de carpa capim alimentados com ração contendo 25 % de farelo de arroz desengordurado (FADE), 25 % de farelo de arroz desengordurado com ácido fítico extraído (FADEX) ou ração controle com ingredientes convencionais (CONT) na nutrição de peixes. Para isso, 300 juvenis de carpa capim (7,37 ± 0,61 g) foram alimentados com ração peletizada três vezes ao dia durante 60 dias em sistema de recirculação de água com temperatura controlada. Aos 30 e 60 dias foram avaliados peso, comprimento total (CT), taxa de crescimento específico (TCE), ganho médio diário (GMD), fator de condição (FC) e conversão alimentar aparente (CAA) e, aos 60 dias, ganho em peso (GP), rendimento de carcaça, deposição de cálcio, fósforo e cinzas nos ossos. O delineamento experimental foi inteiramente casualizado com quatro repetições. Os dados passaram por análise de
Endothelin-1 and nitric oxide in 3-year prognosis after acute myocardial infarction

Background/Aim. Acute myocardial infarction (AMI) is an important cause of mortality/morbidity worldwide. Biomarkers improve diagnostic and prognostic accuracy in AMI. The aim of this study was to investigate an increase of markers of endothelial dysfunction in AMI, measured on the 3rd day after the initial event and to investigate their association with short- and long-term (3-year) prognosis (out-come). Methods . The prospective study included 108 patients with AMI in the experimental group and 50 apparently healthy subjects in the control group. Endothelin-1 (ET-1) and nitric oxide degradation products (NOx) were determined. Results. The average age of the participants in the experimental group was 62 ± 10 years and 59 ± 9 years in the control group; 74.1% of the patients in experimental group were males and 68.8% in the control group. and long-term (3-year) prognosis (outcome). Endothelin-1 positively correlated with conventional prognostic markers in AMI.
Coherent multidecadal variability in North Atlantic sea level

Tide gauge records from around the North Atlantic are examined and found to show variability on 20–30 year time scales. Sea surface height variability along the western boundary of the North Atlantic shows a particularly strong and coherent signal. Similar variability is also found in an ensemble of runs using a state‐of‐the‐art climate model (GFDL CM2.1). This sea surface height variability is linked to variability of temperatures in the upper layers of the ocean and thence to the Atlantic Multidecadal Oscillation. The variability is consistent with the excited internal ocean mode mechanism of multidecadal variability derived from idealised models and the timescale is consistent with that derived from observations of sub‐surface temperature variability.
GENERATOR PARAMETER IDENTIFICATION USING AN EXTENDED PARTICLE SWARM OPTIMISATION METHOD

This paper presents an extended method of particle swarm optimisation (EPSO) to the generator parameter identification problem. Compared with the original particle swarm optimisation (PSO) method, EPSO method uses more particles’ information to control the mutation operation. A new adaptive strategy for choosing parameters is also proposed to assure convergence of EPSO method. Comparison among the three different methodologies, PSO, EPSO and EP, is presented in the paper to show the potential of applications of EPSO method to parameter identification and system modeling, especially in the case of large noise.
How context repetition influences the N400 and reaction times - a metaphor study

In cognitive metaphor research a lot of different variables can exert their influence on the results. To control for all these variables limits the set of possible stimuli used. However, previous studies have already indicated that it may be possible to work with single word repetitions in psycholinguistic studies of language to broaden the set of possible stimuli. The effects of repeating stem sentences on the processing of language are less known. This study aims at expanding existing findings by examining the effect of repeating stem sentences on the processing of metaphorical, literal and anomalous expressions. Participants had to judge whether an expression was metaphorical, literal or anomalous, while N400 ERP responses were recorded. Repetition of stem sentences had no effect on the N400 amplitude. Reaction times were longest for first presentations of the stem sentences compared to second or third presentations. Unexpectedly, faster reaction times for anomalous sentences were found compared to metaphorical and literal sentences, which may be explained by task design. The findings from this study suggest, that it may be possible to work with repetition of stem sentences in psycholinguistic research, without compromising the validity of results.
Leptin as a risk factor for the development of colorectal cancer

Obesity has been associated with many types of cancer, including colorectal cancer (CRC). The mechanisms by which obesity increases the risk for development of CRC can be explained by factors such as hyperinsulinemia, increases in proinflammatory cytokines, estrogens and insulin-like growth factors (IGFs), and alterations in adipokines levels. Leptin is the most abundant adipokine, and has also been associated with an increased risk for development of CRC, as demonstrated by innumerous in vitro and in vivo experiments, and by large epidemiological studies. By binding to its receptor, leptin activates several intracellular cascades, stimulating cell growth and proliferation, inhibiting apoptosis, and promoting angioneogenesis. Leptin has also proinflammatory effects that promote a low-grade inflammatory state and contribute to the development of CRC. A better understanding of the associations between leptin and CRC might lead to the development of novel approaches for the diagnosis, risk stratification, and treatment of CRC.

Positive and Negative Work-family Interaction: How Burnout is Related to Job Satisfaction

Aims: The main objective of this study was to test competitive path models describing the relationship between Work–Home Interference, job burnout and job satisfaction. Study Design: Data was obtained from a sample of 95 dentists. A conceptual model in which burnout totally mediates the relationship between Work–Home Interference and job satisfaction was compared to another model in which this mediation was partial. The mediator role was demonstrated using the rationale and procedure suggested by Holmbeck [1]. The results were discussed in light of the literature dealing with burnout. Sample: Data was obtained from a sample of 95 denstists. Practical Implications: The research suggests the very importance of relationships between work and home life, and the mediator role of job burnout for current research in quality of work
Beta momentum strategy after extreme market movements

The authors adopt an event study method and empirically investigate the performance of a beta momentum strategy (long in past winners of small beta and short in past losers of large beta) after extreme market movements in 20 countries. The researchers find that the beta momentum strategy yields material abnormal returns after controlling for return factors of size (SMB), book-to-market (HML) and momentum (UMD). The results are consistent for both extreme market UP days or DOWN days and regardless of whether the extreme market movements are identified by three percent or two percent cut-off points. In addition, the results based on the beta momentum strategy are more consistent than those of conventional momentum and betting against beta (BAB) strategies over different test windows from (0, +1) days to (0, +90). Finally, the abnormal returns based on momentum, BAB, and our beta momentum strategies are statistically insignificant for the Asian and Australian subsamples, whereas the results are significant for the European and North American samples.
A Tightrope Walk between Legality and Legitimacy: An Analysis of the Israeli Supreme Court's Judgment on Targeted Killing

Abstract The Israeli official policy of targeted killing has often been a subject of controversy and criticism. Although still applied by the state of Israel, this cruel practice was recently limited in a courageous decision handed down by the Israeli Supreme Court. The new restrictions on targeted killing represent an important step towards its criminalization. Despite this, the Court's interpretation of the international humanitarian law requirements is still too broad and there is a need for more restrictive safeguards. In addition, the current uncertainties of this field of law, replicated in the decision, exacerbate the problem further. The main difficulty, however, lies in the theoretical assumption that targeted killing is legal. This article proposes instead to view targeted killing as an exception to the presumption of protection of the civilian population. The authors review the recent trends in international humanitarian law in order to assess the impact of the Court's reasoning. Although this landmark case represents an important breakthrough, it will certainly not be the last word on targeted killing.
