Lasing characteristics of InAs quantum-dot lasers on (001) InP substrate

Single-stack InAs self-assembled quantum-dot (QD) lasers based on (001) InP substrates have been grown by metalorganic vapor-phase epitaxy. The narrow ridge waveguide lasers lased up to 260 K in continuous-wave operation, and near room temperature in pulsed mode, with emission wavelengths between 1.59 to 1.74 μm. Above 200 K, a very low wavelength temperature sensitivity of 0.09 nm/K was observed. Lasing spectra at different temperatures suggests that the ground states and the excited states almost overlap, and form a quasicontinuous band due to the large size of the InAs dots and their inhomogeneous broadening. These results will provide guidance for further development of long wavelength InAs QD lasers based on InP substrates.
Innovation Adoption Behaviour in the Construction Sector: The Case of the Queensland Road Industry

This paper examines ‘imitative’ innovation, which involves the adoption of innovations that are new to a particular business, rather than new to the world. The paper is based on a survey of over 200 participants in the Australian road industry, in the state of Queensland. The survey covered clients, contractors, consultants and suppliers. Innovation directions and levels were measured via adoption patterns, based on a list of technologies and advanced practices presented in the survey questionnaire. The research investigated innovation rates, types, success, impact, drivers, strategies, and obstacles. The paper commences by exploring the term ‘innovation’, before describing and analysing empirical data from the study. The evidence presented points to the: • importance of innovation to business success; • importance of people-centred/non-technical innovation processes; • role played by inadequate resources and perceived risk in impeding innovation activity; • importance of clients in ‘driving’ innovation activity; and • the usefulness of active evaluation systems in maximising the benefits of innovation.
Effects of Arg-vasopressin and corticosterone on IL-1ß-induced modifications of pituitary ACTH-producing cells.

Interleukin 1b (IL-1b) stimulates the hypothalamic- pituitary-adrenal axis, however the autoparacrine effects of IL-1b? on pituitary ACTHproducing cells and the relations among IL-1b and Arg-vasopressin or corticosterone have not yet been analyzed. To address these effects, pituitary monolayer cultures were treated with IL-1b, Arg-vasopressin and corticosterone, either alone or in combined treatment, and an immunocytochemical, morphometric and densitometric study of ACTH-positive cells was carried out. IL-1b significantly increased the percentage and cellular and nuclear size of ACTH-positive cells, and similar effects were found following treatment with Arg-vasopressin. Combined treatment with IL-1b and Arg-vasopressin increased these parameters more than in separate treatments. Corticosterone decreased these parameters and blocked the effects of IL-1b and Arg-vasopressin in the combined treatments. In sum, our results suggest that IL-1b is an auto-paracrine regulator of pituitary ACTH-producing cells, that it reinforces the stimulatory effects of Arg-vasopressin and that corticosterone is an inhibitory regulator of the auto-paracrine effects of IL-1b and Argvasopressin.
Particle Production at CBM in a Thermal Model Approach

The Compressed Baryonic Matter (CBM) experiment planned at Facility for Antiproton and Ion Research (FAIR) will provide a major scientific effort for exploring the properties of strongly interacting matter in the high baryon density regime. One of the important goal behind such experiment is to precisely determine the equation of state (EOS) for the strongly interacting matter at extreme baryon density. In this paper, we have used a thermal model EOS incorporating excluded volume description for the hot and dense hadron gas (HG). We then predict different particle ratios and the total multiplicity of various hadrons in the CBM energy range i.e. from $10$ A GeV to $40$ A GeV lab energies, which corresponds to $4.43$ A GeV and $8.71$ A GeV center-of-mass energies. Our main emphasis is to estimate the strange particles enhancement as well as increase in the net baryon density in CBM experiment. We have also compared our results with the results obtained from various other theoretical approaches existing in the literature such as hadron string dynamics (HSD) model and ultra-relativistic quantum molecular dynamics (UrQMD) etc.
Sparse regularization for functional logistic regression models

We consider the problem of variable selection in logistic regression models where predictors are functions, with the help of sparse regularization. Observations corresponding to the predictors are supposed to be measured repeatedly at discrete time points, and then they are treated as smooth functional data. Parameters included in the functional logistic regression model are estimated by the penalized likelihood method with L1 type penalties. Tuning parameters which control the degree of the regularization are decided by model selection criteria. In order to investigate the effectiveness of the proposed method we apply it to the analysis of real data.
Effect of Boundary-Layer Tripping on Turbulence Generation and Trailing-Edge Noise in Transitional Airfoils

Lewis, James Benjamin MSAE, Embry-Riddle Aeronautical University, August 2017. Effect of Boundary-Layer Tripping on Turbulence Generation, And Trailing-Edge Noise in Transitional Airfoils. The need arises for developing quiet aircraft and silent Unmanned Aerial Vehicles (UAVs) to minimize the environmental effects as well as for stealth missions. We focus here on attempting to directly predict the noise associated with airframe by considering a single isolated airfoil. Developing an ability to directly predict the radiated noise and how it is generated is a first step for passive or active control of the generated noise. We choose herein a NACA0012 airfoil and specific flow condition to test whether we can directly predict the sound in accordance with the corresponding experimental data identified in the Benchmark Problems for Airframe Noise Computations (BANC, 2016). We implement a high-fidelity large-eddy simulation code initially developed by the U.S. Air Force Research Laboratory. To understand the mechanisms involved and possibly control it, we considered both the case of clean (untripped) airfoil as well as a tripped one. Our results for flow near the airfoil surface show that our prediction of the boundary layer and turbulence intensities are consistent with that of experimental results. Tripping, while it does modify the initial transition process, has little effect on the flow fluctuations near the trailing edge. The calculated spectra of the acoustic field as well as its directivity were found to be in close agreement with the experimental data. Tripping had little effect, if any, on the radiated sound. This indicates that, for this case, the dominant noise source is the scattering of the boundary layer fluctuations at the trailing edge.
Brine formation in relation to climate changes and ice retreat during the last 15,000 years in Storfjorden, Svalbard, 76–78°N

Storfjorden, Svalbard, is an area of intense brine formation. The brine is cold, dense, rich in oxygen and CO2, and has reduced pH. Storfjorden is unique because it contains well-preserved agglutinated foraminifera dating back to the beginning of the last deglaciation. We have investigated the distribution of calcareous and agglutinated benthic foraminifera, benthic oxygen and carbon isotopes, calcium carbonate, total organic carbon, and ice-rafted debris in five cores from Storfjorden comprising the Holocene and the deglaciation. The purpose of the study is to reconstruct brine formation in the past under different climate scenarios. The data indicate that in Storfjorden the ratio of agglutinated to calcareous benthic foraminifera can be taken as a measure of the strength of brine formation. The foraminiferal data, which are supported by stable isotopes, degree of fragmentation, and geochemical parameters, signify that brine formation intensified during cold periods and weakened during warm periods. During the deglaciation, increased brine flow coincides with the Older Dryas, the Intra-Allerod Cold Period, and the Younger Dryas. Brine formation increased from circa 8200 years B.P. reaching periodic maxima during the last 4000 years B.P. in response to the unstable climate. Maximum brine production correlates with the Dark Ages Cold Period circa 1500–1100 years B.P. and the Little Ice Age circa 600–100 years B.P. Lower production correlates with the Roman Warm Period circa 2500–2000 years B.P. and the Medieval Warm Period circa 1000–700 years B.P.
Can lower mantle slab‐like seismic anomalies be explained by thermal coupling between the upper and lower mantles?

Below subduction zones, high resolution seismic tomographic models resolve fast anomalies that often extend into the deep lower mantle. These anomalies are generally interpreted as slabs penetrating through the 660‐km seismic discontinuity, evidence in support of whole‐mantle convection. However, thermal coupling between two flow systems separated by an impermeable interface might provide an alternative explanation of the tomographic results. We have tested this hypothesis within the context of an axisymmetric model of mantle convection in which an impermeable boundary is imposed at a depth of 660 km. When an increase in viscosity alone is imposed across the impermeable interface, our results demonstrate the dominant role of mechanical coupling between shells, producing lower mantle upwellings (downwellings) below upper mantle downwellings (upwellings). However, we find that the effect of mechanical coupling can be significantly weakened if a narrow low viscosity zone exists beneath the 660‐km discontinuity. In such a case, both thermally induced ‘slabs’ in the lower mantle and thermally activated plumes that rise from the upper/lower mantle boundary are observed even though mass transfer between the shells does not exist.

Anatomical Measurements of the Distal Clavicle in a Kenyan Population

Anatomical measurements of the distal clavicle are important in the design of clavicular implants for fixing clavicular fractures and reconstruction of the coraco-clavicular complex in acromio-clavicular joint dislocations. These measurements show population variations however, little data exists from the African population and none for the Kenyan one. One hundred and eighty unpaired dry adult human clavicles were obtained from the Department of Human Anatomy, University of Nairobi. The length of clavicle and distance of conoid and trapezoid tuberosities from the distal end were measured using a ruler. The superoinferior thickness of the distal end was measured using a vernier caliper. The mean clavicle length was 148.57±12.63mm. The left clavicle was longer (150.4mm) than the right one (146.8mm). Conoid tubercle (CT) and trapezoid tuberosity (TT) were 39.52±5.93mm and 17.96±3.42mm respectively from the lateral edge of clavicle. These distances correlated positively with the length of clavicle and occupied 0.3 and 0.15 of total clavicular length respectively. The supero-inferior thickness of the lateral edge was 10.09±2.36mm. The distance of CT and TT positively correlated with clavicular length. The CT lies at a junction of lateral one third and medial 2/3 while the TT is midway between CT and lateral end. Designers of clavicular implants should consider these measurements and surgeons involved in fixation of acromoclavicular joints fractures. Key words : Clavicle, conoid tubercle, trapezoid tuberosity.

Evaluation of Dietary Supplementation of Delta-aminolevulinic Acid and Chito-oligosaccharide on Production Performance, Egg Quality and Hematological Characteristics in Laying Hens

The effects of delta-aminolevulinic acid (DALA) or chito-oligosaccharide (COS) in layer diets on production performance, egg quality and hematological characteristics were investigated in this 8-week trial. Two hundred and seventy 27-week-old (Hy-Line brown) layers were randomly assigned to 5 treatments with 9 replications per treatment. Dietary treatments were i) Control (basal diet); ii) DALAI (basal diet+DALA 2 mg/kg); iii) DALA2 (basal diet+DALA 4 mg/kg); iv) COS1 (basal diet+COS 100 mg/kg) and v) COS2 (basal diet+COS 200 mg/kg). In this study, no significant difference was observed in feed intake and egg shell quality (eggshell breaking strength and egg shell thickness) among treatments. The inclusion of DALA increased egg production during the first 4 weeks. Egg weight was increased in both DALA (quadratic, p<0.05) and COS (linear, p<0.05) treatments compared with the control treatment. Laying hens fed the DALA treatment had an increased yolk color unit (quadratic, p<0.05) and haugh unit (linear, p<0.05) compared with the control group. Similarly, these characteristics were also affected by COS treatments, with both values being linearly increased (p<0.05) in COS treatments compared with the control treatment. Additionally, birds fed DALA treatments significantly increased (quadratic, p<0.05) the number of RBC, WBC and lymphocytes compared with the control treatment. Dietary DALA supplementation linearly increased (p<0.05) the serum iron concentration at the end of the 8th week. The inclusion of COS increased (linear, p<0.05) the concentration of RBC, WBC and lymphocytes compared with the control treatment. In conclusion, dietary DALA at the lower dosage (2 mg/kg) could exert better effects in laying hens than higher dosage (4 mg/kg). Birds fed DALA supplemented diet had an increased iron availability, egg weight, eggshell quality and immunity. Moreover, the inclusion of COS (200 mg/kg) can increase egg weight, eggshell quality and immunity in laying hens. Therefore, both the utilization of COS and DALA could be considered as a new strategy for optimizing egg quality and health condition of laying hens.
EFFECTS OF DIETARY SUPPLEMENTATION LEVELS OF TURMERIC POWDER ( CURCUMA LONGA ) ON PERFORMANCE , CARCASS CHARACTERISTICS AND GUT MICROFLORA IN BROILER CHICKENS

The study was conducted to determine the effect of turmeric powder at different levels (0, 2, 4, 6, 8, 10 g/ kg), and a single dose of chlortetracycline (10 mg/kg) to broiler diets on performance, carcass yield and gut microflora. The results revealed that adding 10 g/kg turmeric powder to the ration significantly decreased feed intake (FI). Meanwhile, adding 2 g/kg turmeric powder improved feed conversion ratio (FCR). Neither carcass yield nor weights of heart and liver organs were significantly affected by dietary treatments. The colony forming unit of lactic acid bacteria was found to be higher in the group of birds fed on the diet supplemented with 2 g/kg turmeric powder than the other groups of birds. While the highest E. coli content was determined in the birds received control diet and those received the diet added with 10 mg/kg antibiotic, the lowest E. coli content was determined in the groups of birds fed with the diets added with 6, 8 and 10 g/kg turmeric powder.In conclusion, increasing dieatry supplementation levels of turmeric powder, except for the 10 g/kg level has positive effects on bird’s performance and gutmicroflora. In particular, a level of 2 g/kg turmeric powder could be recommended as an alternative to feed antibiotics due to significantly improved FCR.
Perceived Organisational Support and Its Impact to Teachers ’ Commitments : A Malaysian Case Study

This study examined the role of perceived organisational support in developing teachers’ commitment. Using organisational support theory, we reasoned that organisational support perceived by teachers influenced their commitment to the organisation and profession. Questionnaires were distributed among teachers in nine primary schools in Malaysia, namely in Kuala Lumpur, Selangor, and Pahang area. A total of 221 usable questionnaires were obtained which is about 74 per cent rate of return. Data analyses involved correlation, and regression test. Consistent with our hypotheses, we found that perceived organisational support was positively associated with teachers’ commitment (i.e., affective, continuance, normative). The results of this study urge further attention to teachers’ issues, concerns and needs in creating a better policies and support.
Ana Júlia Fernandes Moreira

Understanding the type of lexical-semantic connections and their establishment in second language (L2) acquisition is a main topic in bilingualism research. Recent studies showed the learning method used (picture vs. word-based methods) influence the access to the conceptual system in early stages of L2 learning (Comesaña et al., 2009). Moreover, this effect seems to vary according to word status, especially in children (Comesaña et al., 2012a). This study aimed to further explore list composition effects in the establishment of L2 wordsto-concepts connections by using a picture-based method. Fifth-grade children were taught cognate and noncognate words, presented separately or in a mixed way. Afterwards, they performed a backward-translation recognition task. Results revealed, as expected, that children took longer and made more errors when rejecting semantically related than unrelated words as correct translations (semantic interference effect). Importantly, a differential processing for cognate words was observed in the blocked condition. These findings are discussed within the light of the Revised Hierarchical Model (Kroll & Stewart, 1994).
Plant Regeneration Capacity of Calluses Derived from Mature Seed of Five Indonesian Rice Genotypes

Abstract Establishment of a suitable system for plant regeneration of rice calluses derived from mature seed is a prerequisite for genetic transformation using callus as the target tissue. Selecting the most suitable medium and assessing the genotype performance for in vitro response are essential requirement for this purpose. The experiment with five Indonesian rice genotypes showed that callus-proliferation capacity (CPC) and callus-growth capacity were significantly affected by genotype and CPC by medium. The shoot-regeneration capacity and plantlet-regeneration capacity were affected by the interaction effect between genotype and medium. However for green plant-regeneration capacity, it was affected independently by genotype and medium. Culture media D1 and NB5 were the most suitable media for callus subculture and plant regeneration, respectively. Genotypes Fatmawati and BP-140 consistently performed best in the callus subculture and plant regeneration.
Benford ’ s Law and Earnings Management Detection : The Case of REITs

A mathematical property, which has become known as Benford’s Law, was discovered independently by Newcomb (1881) and Benford (1938). Benford’s Law holds that, contrary to intuition, the digits in large sets of positive-valued, naturally occurring numbers that range over many orders of scale are not uniformly distributed. Instead, they often (but not always) follow a logarithmic distribution such that numbers beginning with smaller digits appear more frequently than those beginning with larger ones. Because manipulated, unrelated, or created numbers usually do not follow a Benford distribution, Benford’s Law has been used to identify suspicious data in a variety of settings. Financial auditors, for example, routinely check individual firm data for compliance with Benford’s Law (Kumar and Bhattacharya, 2007), and researchers have used Benford’s Law to investigate whether financial data has been manipulated for a group of firms or an entire industry.
Evaluation of PLAGA/n-HA Composite Scaffold Bioactivity in vitro

Polymeric sintered microsphere scaffolds have shown their tremendous potential in bone tissue engineering applications due to their highly porous and interconnected three dimensional structure and excellent mechanical properties. While these scaffolds are able to support basic cellular activity after seeding cells on them, the bioactivity of these scaffolds in terms of enhancing the biological performance of stem cells during bone regeneration is still under satisfactory. We hypothesized that incorporation of bioactive addictive such as hydroxyapatite into these scaffolds could improve their bioactivity without sacrificing the bulk properties of the scaffolds. We have successfully incorporated nano-hydroxyapatite (n-HA) into poly (lactic acid-glycolic acid) (PLAGA) microsphere based scaffolds in our previous studies. Herein, we aimed to evaluate the bioactivity of PLAGA/n-HA composite scaffolds, with a focus on studying the mineralization of the scaffolds in vitro. The capability of inducing apatite formation in vitro was largely enhanced in the composite scaffolds compared to plain PLAGA scaffolds. More importantly, PLAGA/n-HA composite scaffolds have been shown to improve rabbit mesenchymal stem cells (RMSCs) proliferation, differentiation, and mineralization as compared to control PLAGA scaffolds. Taken together, introduction of n-HA appears to be an efficient approach to improve the bioactivity of PLAGA scaffolds for bone tissue engineering.
