Three-dimensional printed millimetre wave dielectric resonator reflectarray

Reflectarray antennas have attracted extensive attention due to their low loss, high gain, compact volume, and their excellent abilities to control the radiated beam. The use of dielectric resonators as the reflectarray elements minimises the ohmic loss and the coupling between elements. This study uses fused deposition modelling (FDM) three-dimensional (3D) printing rapidly prototyping a low cost and light-weight dielectric resonator reflectarray. The demonstrated reflectarray is composed of 625 3D printed dielectric resonator elements to control the reflected phase over the reflector surface. The total size is 12 × 12 cm2 and the mass is 67 g. Measurements show that this reflectarray provides 28 dBi gain at 30 GHz when offset fed by a Ka-band horn antenna. This work demonstrates the potential of FDM for millimetre wave (mm-wave) applications. The new 3D printing approach can be deployed for high-gain mm-wave antenna fabrication with significantly reduced labour time and material costs.
Prevalence and Risk Factor Analysis of Equine Infestation with Gastrointestinal Parasites in Israel

The horse is a host for a large number of intestinal helminthic parasites. This study was designed as a survey for the prevalence, species distribution and potential risk factors of equine intestinal helminth parasites among horses in Israel. Fecal floatation and egg counts were performed on 485 fecal samples collected from 403 horses (mostly adults) at 30 farms across Israel. Strongyle eggs were found in 116/485 (24%) of the samples from 18/30 (60%) farms, of which 44 (38% of positive samples, 9% of the total population) were highly infested (over 500 eggs/gm feces). Ascarids were found in 26/485 (5%) samples from 10/30 (33%) farms, 7 (27% of positive samples, 1.4% of the total population) of which were highly infested. Singular flatworm eggs (family Anoplocephala) were detected in two samples. Risk factors significantly (p<0.005) associated with Strongyle infestation by the univariate statistical analysis were the farm, geographical location, age of the horse and breed, and the time of last deworning treatment. Season, horse gender, horse age, and housing were significantly associated with ascarid infestation.Infestation with gastrointestinal helminths in Israel appears to be low, and resistance against anthelminthics in adult horses is probably uncommon. These findings should lead to re-investigation and re-evaluation of deworming regimes in Israel recommended for adult horses in equine facilities in areas with low infestation rates.
Low Temperature Expansion in the Lifshitz Formula

The low temperature expansion of the free energy in a Casimir effect setup is considered in detail. The starting point is the Lifshitz formula in Matsubara representation and the basic method is its reformulation using the Abel-Plana formula making full use of the analytic properties. This provides a unified description of specific models. We rederive the known results and, in a number of cases, we are able to go beyond. We also discuss the cases with dissipation. It is an aim of the paper to give a coherent exposition of the asymptotic expansions for . The paper includes the derivations and should provide a self-contained representation.
Relation between Type of Personality and Academic Performance among Malaysian Health Sciences Students

Background: This study was carried out to determine the relationship between types of personality and level of academic performance among health sciences students in Malaysia. Methods: A total number of 246 students were participated in this study. The questionnaire was distributed randomly from students of each semester. Data were entered and analyzed using PASW Statistics Version 18.0. Relationship between GPA and BFA were analyzed using the multiple linear regressions. The Spearman’s correlation, multiple li near regression were used in this study. Findings were presented with adjusted OR, 95% CI and p-value. Results: The majority of the study participants were single (98%), Malay (62.2%). This study revealed that the most dominant personality trait was openness (32.8 ± 5.1) and the least dominant was neuroticism (23.9 ± 4.4). Spearman’s correlation analysis showed that there was correlation between GPA and the following types of personality: openness (p=0.001), conscientiousness (p<0.001), extraversion (p=0.018). Multiple linear regression analysis showed that openness and conscientiousness personalities were positively associated with academic performance (p=0.047, p=0.036; respectively). Conclusion: Our study, for the fist time, assessed the relationship between types of personality and level of academic performance among health sciences students in Malaysia. Openness and conscientiousness personalities were found to be positively associated with academic performance.
MICROCREDIT IN THE CONTEXT OF POLITICAL AND FISCAL DECENTRALIZATION

A growing number of developing countries are decentralizing, but is decentralization capable of creating a more enabling environment for pro-poor programs? This paper uses microcredit as an example of such a service and employs OLS regressions to examine the effect of political and fiscal decentralization on the operational and social efficiency of MFIs. The results suggest that political decentralization is linked with higher efficiency but it is outweighed by the negative effect of relying on intergovernmental transfers. In less developed countries, political decentralization’s positive correlation with MFI efficiency decreases and fiscal decentralization has a less negative effect.
Assessing the sensitivity and specificity of fish community indicators to management action

We assessed ten trophodynamic indicators of ecosystem status for their sensitivity and specificity to fishing management using a size-resolved multispecies fish community model. The responses of indicators to fishing depended on effort and the size selectivity (sigmoid or Gaussian) of fishing mortality. The highest specificity against sigmoid (trawl-like) size selection was seen from inverse fishing pressure and the large fish indicator, but for Gaussian size selection, the large species indicator was most specific. Biomass, mean trophic level of the community and of the catch, and fishing in balance had the lowest specificity against both size selectivities. Length-based indicators weighted by biomass, rather than abundance, were more sensitive and specific to fishing pressure. Most indicators showed a greater response to sigmoid than Gaussian size selection. Indicators were generally more sensitive at low levels of effort because of nonlinear sensitivity in trophic cascades to fishing mortality. No sing.
Understanding the Cash Flow-Fundamental Ratio

This article investigates the use of cash flow-fundamental ratio in forecasting stock market return and examines implications behind this ratio. By presuming the dynamics of cash flow-fundamental ratio I identify the relationship between economic uncertainty and risk premium. The evidence shows that cash flow-fundamental ratio is procyclical and is a predictor of cash flow growth and excess returns. The cash flow-fundamental ratio is proved to be negatively associated with risk premium. I also examine that the mean-reversion property of cash flow-fundamental ratio is triggered by profitability. In contrast to the assumption of stationary in stock price, mean reversion in profitability is more reasonable and has been proved by Fama and French (2000).
Women on boardroom: Does it create risk?

Abstract This study examines the impact of the women existence on corporate board. It is believed that the existence of women on board adds more value to the company as more women bring different perspectives on the decision-making process and the company’s strategic plans. Using Islamic listed-firms in the Indonesian Stock exchange, this study employs 7-year panel data comprising 840 observations from 2009 to 2015 quarterly data of 30 listed-firms that comply with Islamic law. Generalized Least Square is employed in this study and the results revealed that the presence of female CEOs has lowered the firm’s risk for all risk proxies. Female CEOs having a higher academic qualification, overseas qualification, and business degree tends to lower the firm’s risk. The result also indicates that the younger the age of female CEOs and the longer tenure of the female CEOs, the lower the firm’s risk. Furthermore, more female directors on boardroom have a significant impact on firm’s risk as the higher the number of female directors the lower the firm’s risk (CR and FCF). In addition, female chief financial officer tends to lower the firm’s risk as they are believed to be more conservative in dealing with the financial issues.
HERBAL METHIONINE (METHIOREP®) IMPROVES GROWTH PERFORMANCE OF BROILER CHICKENS WITHOUT AFFECTING CARCASS CHARACTERISTICS AND BLOOD INDICES

Methiorep®, an herbal methionine premix, which is reported to contain herbal ingredients that mimic the activity of Methionine such as SAMe (S-Adenosyl Methionine) and phosphatidyl choline, have recently introduced to Nigeria animal feed industry. An experiment was conducted with 120, one-week-old broilers to evaluate the effect of herbal methionine (methiorep®) as substitute for synthetic methionine on growth performance of broiler chickens. Five isocaloric and isonitrogenous diets were formulated and Diet 1 (control), comprised of 0.25% methionine (NRC, 1994) while diet 2, 3, 4 and 5 comprised of 25%, 50%, 75% and 100% Methiorep® as substitute for methionine in the diets. The birds were randomly allocated to five experimental treatments, each treatment was replicated three times with eight birds per pen in a completely randomized design. The study lasted 49-days. The results of growth performance revealed that body weight gain, average feed intake and feed conversion ratio at both starter and finisher phases were not influenced by dietary treatments (P>0.05). However cost per kg feed decreased as the level of Methiorep® increased in the diets (P<0.05). The results of blood profiles and carcass characteristics were not influenced (P>0.05) by the dietary treatments. It was concluded that Methiorep® can completely substitute for Methionine in the diets of broiler chickens without adverse effect on growth performance, blood profiles and carcass yield of birds.
Gait analysis in children after the lengthening of the lower limb by the Ilizarov technique

IN T R O D U C T IO N : Distraction osteogenesis for the correction of axial deformities and short lower limbs is a long-term process which adversely affects the functional state of the locomotor system and the child's emotions. Therefore, the aim of the study was to analyse the spatiotemporal parameters of gait, and to compare the results of treatment in children after lengthening the tibia or femur by the Ilizarov technique. M A T E R IA L AN D M ET H O D S : The study was performed in 40 children with lower limb asymmetry treated in the Department of Clinical Orthopaedics in Sosnowiec in 2000–2006. Each child was subjected to osteodistraction treatment using the Ilizarov technique. The subjects were divided into two subgroups: group 1 consisted of 20 children who had Ilizarov tibial lengthening, and group 2 consisted of 20 children who had Ilizarov femoral lengthening. Gait analysis was carried out using a dedicated system from Zebris, in which the patient is expected to walk along an approx. 2-metre long marked trajectory. The treadmill platform responded to the load, which enabled evaluation of the ground reaction force and the spatiotemporal parameters of gait. After completing measurements, the system produced a report with values of the tested parameters. R E S U L TS : The study shows that both in children with a lengthened femur or tibia, three of the five subphases of the stance phase in the operated on limb and unoperated on limb were longer, and two shorter as compared to the normal values reported by J. Perry. The subphases of initial contact, loading response and midstance were longer, while the terminal stance and preswing were shorter. C O N C L U S IO N S : In children with a short lower limb treated with the Ilizarov technique, a better outcome was achieved after lengthening the femur compared to the tibia. The gait cycle in children after limb elongation is different from normal.
Combined effects of high pressure and heat on shear value and histological characteristics of bovine skeletal muscle

Changes in shear force value, transverse sections, myofibrils and intramuscular connective tissue of bovine skeletal muscle exposed to the combination of high-pressure up to 400 MPa and heat (30 and 60°C) were studied. The shear force value decreased by pressure-heat treatment up to 200 MPa at 30 and 60°C, and then slightly increased over 200 MPa at 30°C. Shear force values of treated muscles were lower than those of untreated ones. Gaps between muscle fibers in the untreated muscle were a little clear, and then they became very clear in the treated muscles up to 200 MPa at 30 and 60°C. However, the gaps reduced significantly over 200 MPa at 30°C. The remarkable rupture of I-band and loss of M-line materials progressed in the myofibrils with increasing pressure applied. However, degradation and loss of the Z-line in myofibrils observed in the muscle treated at 60°C was not apparent in the muscle treated at 30°C. The length of the sarcomere initially contracted by pressure-heat treatment of 100 MPa at 30°C seemed to have recovered with increase of the pressure up to 400 MPa. In the muscle treated at 60°C, the length of sarcomere gradually decreased with increase of the pressure up to 400 MPa. In the treated muscles, changes in the honeycomb-like structure of endomysium were observed and accelerated with increase of the pressure. A wavy appearance clearly observed at the inside surface of endomysium in the untreated muscles gradually decreased in the treated muscles with increase of the pressure. Tearing of the membrane was observed in the muscles treated over 150 MPa at 30°C, as observed in the sample pressurized at 100 MPa at 60°C. The roughening, disruption and fraying of the membrane were observed over 200 MPa at 60°C. From the results obtained, the combination of high-pressure and heat treatments seems to be effective to tenderize tough meat. The shear force value may have some relationship with deformation of intramuscular connective tissue and myofibrils.
The P rehistoric Peopling of South America as Inferred from Epigenetic Dental Traits

The origins and genetic relations of New World populations have long been topics of scientific interest to physical anthropologists and archaeologists alike (Hrdlicka 1923, 1937). Because of a number of recently reported archaeological sites and human remains, the initial colonization of the New World is a topic of much discussion in both the popular press (Begley and Murr 1999; Malcomson 2000; Nova, “Mystery of the First Americans” 2000; Schurr 2000; Various Authors, Discovering Archaeology 2000) and scientific community (Jantz and Owsley 1998a, b; Neves and Blum 2000; Neves et al. 1999a, b, c, d, 2001; Powell 2000; Powell and Neves 1998, 1999; Powell and Rose 1999; Steele and Powell 1999). Turner’s (1969, 1971, 1981, 1983, 1985, 1990) investigations of genetically controlled discrete dental trait variability are, perhaps, the most comprehensive investigations on the origins of New World human biological variation. His surveys of dental trait variability reveal that Northeast Asians and all Native American populations demonstrate a more complex pattern of tooth cusp and root number relative to Southeast Asians. Turner refers to populations exhibiting this increased complexity of dental traits as “sinodonts,” whereas the more simple dental condition observed among southeast Asians, Australians, and Pacific Rim populations is referred to as “sundadonty. ” Turner (1985, 1986, 1987, 1990) estimates that sinodont dental traits evolved in northeast Asia from pre-existing, less elaborate “sundadont” tooth cusp and root traits approximately 20,000 years before present. For this study, I report on genetically influenced tooth root and cusp traits for 12 south central Andean mortuary populations and compare them to other previously reported samples in order to shed light on the genetic origins and number of migrations for prehistoric South America. I then consider broader implications of these results in light of current archaeological and paleoclimatic data.
Unravelling the potential of halophytes for marine integrated multi-trophic aquaculture (IMTA) a perspective on performance, opportunities and challenges

The present study critically analyses peer-reviewed literature addressing the potential of halophytes to remediate nutrient-rich effluents from marine and coastal aquaculture, as well as the potential for their economic valorization, from human consumption to an untapped source of valuable secondary metabolites with pharmaceutical potential. The growing body of evidence discussed in this review supports the perspective that halophytes can become a new source of nutrition and other high-value compounds and be easily incorporated into saltwater-based integrated multi-trophic aquaculture (IMTA) systems. In this context, halophytes act as extractors of dissolved inorganic nutrients, primarily nitrogen and phosphate, usually wasted in marine aquaculture farms. Phytoremediation using halophytes has been proven to be an efficient solution, and several ways exist to couple this practice with land-based marine aquaculture systems, namely through constructed wetlands and aquaponics. Focusing research on ecosystem-based approaches to aquaculture production will provide valuable data for producers and policy makers in order to improve decision making towards a sustainable development of this economic sector. Ecointensification of aquaculture through IMTA will potentially increase the overall productivity and resilience of the sector, and halophytes, in particular, are on the verge of becoming key players for the diversification and promotion of land-based IMTA. This work specifically documents the uncharted potential of Halimione portulacoides, an important halophyte in European salt marsh ecosystems, as a new extractive species for IMTA.
Fission of actinides using a tabletop laser

– Powerful tabletop lasers are now available in the laboratory and can be used to induce nuclear reactions. We report the first demonstration of nuclear fission using a high repetition rate tabletop laser with intensities of 10W/cm. Actinide photo-fission has been achieved in both U and Th from the high-energy bremsstrahlung radiation produced by laser acceleration of electrons. The fission products were identified by time-resolved γspectroscopy. Introduction. – Nuclear reactions induced by ultraintense lasers became amenable in the last couple of years by the evolution of experimental relativistic laser plasma physics. Highly sophisticated tabletop laser systems generate ultrashort laser pulses focusable to intensities of 10 W/cm. Matter in the focal spot is instantaneously turned into a hot dense plasma. In this intense light field electrons are accelerated to relativistic energies and the dense plasma heats up to temperatures of several MeV. Maximum detected energies of emitted particles (electrons, positrons, protons, neutrons) and photons (bremsstrahlung) reach tens or even hundreds of MeV [1–4]. Laser interaction with matter at these very high intensities is of relevance in a number of areas ranging from advanced accelerator concepts using plasmas, to astrophysics and inertial confinement fusion. The highly energetic particles and photons emitted by the plasma can induce nuclear reactions such as photofission (γ, f) or photo-neutron generation (γ, n) by bremsstrahlung photons [5–9]. These reactions which occur above specific energy thresholds provide a technique for the calibration of bremsstrahlung spectra of laser plasmas in an energy range above a few MeV and therefore allow for the investigation of mechanisms responsible for heating of plasmas to relativistic temperatures.

Writing Effective Business Memos in Alawdah Company Using Action Research

Writing skills are essential skills in the age of technological innovations. This study aimed to improve written communication among Alawdah Company staff. The purpose of this study was to improve written communication among Alawdah Company staff, with a particular focus on more effective business memoranda. Krathwohl (2004, p. 5) offered "two contrasting but equally important methods of doing research," generally described as either quantitative or qualitative methods. However, Creswell (2005, p. 52) explained that the two methods can be combined "to best understand and explain a research problem". The research methodology used to conduct this study was a combined quantitative/qualitative research method with an action research design. Creswell (2005, p. 53) defined action research design as "systematic procedures by teachers (or other individuals in an educational setting) to gather quantitative and qualitative data to address improvements in their educational setting, their teaching, and the learning of their students". Krathwohl (2004, p. 588-90) included action research in the broader context of evaluation studies and explained that, while evaluation may be identical to other forms of research in form, they differ in intent. While most other research methods and designs are aimed at discovering or validating a generalization, evaluations are aimed at making decisions, improving, expanding, or discontinuing programs. As stated earlier, the purpose of the present study was to help Alawdah employees write effective business memoranda.
Investigating ‘Aspect’ in NMT and SMT: Translating the English Simple Past and Present Perfect

One of the important differences between English and French grammar is related to how their verbal systems handle aspectual information. While the English simple past tense is aspectually neutral, the French and Spanish past tenses are linked with a particular imperfective/perfective aspect. This study examines what Statistical Machine Translation (SMT) and Neural Machine Translation (NMT) learn about 'aspect'and how this is reflected in the translations they produce. We use their main knowledge sources, phrase-tables (SMT) and encoding vectors (NMT), to examine what kind of aspectual information they encode. Furthermore, we examine whether this encoded 'knowledge'is actually transferred during decoding and thus reflected in the actual translations. Our study is based on the translations of the English simple past and present perfect tenses into French and Spanish …
Common Macro Factors and Currency Premia

We study the role of domestic and global factors in the payoffs of portfolios mimicking carry, dollar-carry, and momentum strategies. Using factors summarizing large data sets of macroeconomic and financial variables, we find that global equity-market factors are predictive for carry-trade returns, whereas U.S. inflation and consumption variables drive dollar-carry-trade payoffs, momentum returns are predominantly driven by U.S. inflation factors, and global factors capture the countercyclical nature of currency premia. We also find predictability in the exchange-rate component of each strategy and demonstrate strong economic value for risk-averse investors with mean-variance preferences, regardless of base currency.
