Fragmentation, infall, and outflow around the showcase massive protostar NGC7538 IRS1 at 500 AU resolution

Aims: Revealing the fragmentation, infall, and outflow processes in the immediate environment around massive young stellar objects is crucial for understanding the formation of the most massive stars. Methods: With this goal in mind we present the so far highest spatial-resolution thermal submm line and continuum observations toward the young high-mass protostar NGC7538 IRS1. Using the Plateau de Bure Interferometer in its most extended configuration at 843mum wavelength, we achieved a spatial resolution of 0.2"x0.17", corresponding to ~500AU at a distance of 2.7\,kpc. Results: For the first time, we have observed the fragmentation of the dense inner core of this region with at least three subsources within the inner 3000 AU. The outflow exhibits blue- and red-shifted emission on both sides of the central source indicating that the current orientation has to be close to the line-of-sight, which differs from other recent models. We observe rotational signatures in northeast-southwest direction; however, even on scales of 500 AU, we do not identify any Keplerian rotation signatures. This implies that during the early evolutionary stages any stable Keplerian inner disk has to be very small (<=500 AU). The high-energy line HCN(4-3)v2=1 (E_u/k=1050K) is detected over an extent of approximately 3000 AU. In addition to this, the detection of red-shifted absorption from this line toward the central dust continuum peak position allows us to estimate infall rates of ~1.8x10^(-3)Msun/yr on the smallest spatial scales. Although all that gas will not necessarily be accreted onto the central protostar, nevertheless, such inner core infall rates are among the best proxies of the actual accretion rates one can derive during the early embedded star formation phase. These data are consistent with collapse simulations and the observed high multiplicity of massive stars.
Evaluation of Eucalyptus tereticornis, Tagetes minuta and Carica papaya as Stored Maize Grain Protectants against Sitophilus zeamais (Motsch.) (Coleoptera: Curculionidae)

Sitophilus zeamais (Motsch.) is an important storage pest of maize grain in several parts of Africa including Zimbabwe. Although synthetic pesticides are effective at controlling the pest, environmental and health hazards of these chemicals are of increasing concern. The study assessed efficacy of botanical leaf powders of Eucalyptus tereticornis, Tagetes minuta and Carica papaya in controlling S. zeamais using rates of 5 g, 10 g and 20 g per 200 g of open pollinated maize grain (variety ZM421). The trial was laid in a completely randomised design (CRD), with 12 treatments replicated three times. The grain was put in a freezer at -4oC for a fortnight, before the botanicals were added, to kill any prior sources of weevil inoculum and eggs which might be already pre-existing in the grain. 200 g maize grain was infested with 200 three week old unsexed pure culture weevils in 750 ml jars. After 14, 28, 42, 56 and 70 days, weevils were sieved and their mortality determined. Percentage grain weight loss was assessed after 35 days post pests introduction. There were significant differences (p<0.05) in number of weevil mortality and grain weight loss among treatments and their application rates. The findings showed that conventional chemical control was most effective than all botanicals used. E. tereticornis was the most effective of all the botanical pesticides at an application rate of 20 g as evidenced by high weevil mortality and less grain weight loss. It was concluded that botanicals have storage pesticidal properties to suppress S. zeamais in maize grain and could be used as an alternative control option to synthetic pesticides.
A Causal Model of Breast Cancer Preventive Behaviors among Female Relatives of Thais with Breast Cancer

The purpose of this study was to test the Casual Model of Breast Cancer Preventive Behaviors among 200 first-degree female relatives of Thais with breast cancer. Development of our hypothesized Model was informed by the Health Belief Model and a literature review. A total of 200 relatives of patients receiving treatments at a tertiary care hospital in Bangkok were recruited using convenience sampling. Data collection used six self-administered questionnaires: The Demographic Data Form, Perceived Risk Questionnaire, Impact of Event Scale, Powe Fatalism Inventory, Perceived Self-efficacy Scale, and Health-Promoting Lifestyle Behavior Questionnaire. Descriptive statistics were used to describe the demographic characteristics of the participants, while path analysis was undertaken using AMOS.The results showed that the final Model fitted well with the empirical data of all variables, except the relative breast cancer index, and explained 52% and 49 % of the total variance in breast cancer screening and healthy lifestyles, respectively. Age and education had an indirect effect on these behaviors through breast cancer fatalism, perceived self-efficacy, and perceived risk while breast cancer specific distress had indirect effect only through perceived risk. Breast cancer fatalism had the lowest effect, whereas perceived risk and perceived self-efficacy had the strongest effect on both breast cancer screening and healthy lifestyle. Our findings suggest that nurses should conduct interventions to enhance perceived self-efficacy and perceived risk of breast cancer for motivating these high-risk women to perform regular breast cancer prevention behaviors. Further, longitudinal research to refine our Model with women with a family history of breast cancer is recommended.
A compact polymer optical fibre ultrasound detector

Polymer optical fibre (POF) is a relatively new and novel technology that presents an innovative approach for ultrasonic endoscopic applications. Currently, piezo electric transducers are the typical detectors of choice, albeit possessing a limited bandwidth due to their resonant nature and a sensitivity that decreases proportionally to their size. Optical fibres provide immunity from electromagnetic interference and POF in particular boasts more suitable physical characteristics than silica optical fibre. The most important of these are lower acoustic impedance, a reduced Young’s Modulus and a higher acoustic sensitivity than single-mode silica fibre at both 1 MHz and 10 MHz. POF therefore offers an interesting alternative to existing technology. Intrinsic fibre structures such as Bragg gratings and Fabry-Perot cavities may be inscribed into the fibre core using UV lasers. These gratings are a modulation of the refractive index of the fibre core and provide the advantages of high reflectivity, customisable bandwidth and point detection. We present a compact in fibre ultrasonic point detector based upon a POF Bragg grating (POFBG) sensor. We demonstrate that the detector is capable of leaving a laboratory environment by using connectorised fibre sensors and make a case for endoscopic ultrasonic detection through use of a mounting structure that better mimics the environment of an endoscopic probe. We measure the effects of water immersion upon POFBGs and analyse the ultrasonic response for 1, 5 and 10 MHz.
Liberalization and the Behavior of Output During the Transition from Plan to Market

This paper deals with liberalization and the evolution of output during the transition from plan to market. It explains why strong liberalization leads to a comparatively steep fall in output early in the transition, but a relatively strong recovery later on. Because it takes time to restructure the capital stock inherited from the old system, liberalization initially leads to transitional unemployment of capital and the contraction of the old enterprise sector. By making room quickly for the new, more efficient enterprises, however, liberalization also sets the stage for recovery and a much higher level of income in the medium term.
Synthesis of N-vinylpyrrolidone/Acrylic acid nanoparticles for drug delivery: Method optimization

*Corresponding author: tonglairoum_p@su.ac. th; Tel. : +66-08-5191-2848 Abstract. There are various approaches to deliver therapeutic agents to the preferred target. Polymeric nanoparticles were found to have pleasing suitability as a drug carrier. The goal of this research was to optimize the synthesis method to obtain the desirable %yield and particle properties of the new biocompatible polymer-based nanoparticles. The non-toxic polymer, N-vinyl pyrrolidone (NVP) and a widely used hydrophilic biocompatible acrylic acid (AA) monomer were used to form the drug nanocarriers. The synthesis method was optimized by changing the types of initiator (KPS or V50) and the monomers molar ratio (NVP:AA). It was found that by varying both the monomer molar ratio and the type of reaction initiator, did not have significant effect on the physicochemical characteristics of the nanocarriers. The FTIR spectra of all products exhibited the peaks of carboxylic acid, carbonyl, and tertiary amine functional group vibration. The particle size of the nanocarriers was in the range of 173.6 ± 18.4 to 201.4 ± 17.1 nm with negative surface charge. However, the yield obtained increased as the initiator was altered from KPS to V50, and when the acrylic acid molar ratio was increased from 1:1 to 1:3. In conclusion, changing the initiator and monomer molar ratio may affect the physicochemical properties of the nanocarriers and the %yield of the nanocarrier product. Further investigations are essential to obtain the favorable drug nanocarriers for drug delivery.
Financial Development and the Velocity of Money in Nigeria: An Empirical Analysis

The paper investigates the impact of financial development on the velocity of money in Nigeria, over the time horizon 1986:1 — 2010:4. The paper confirms the existence of a unique and statistically significant relationship between velocity of money (narrow and broad) and measures of financial development. The error-correction results show that current exchange rate has statistically significant negative effect on velocity of money in Nigeria. Per capita income has statistically significant relation with velocity of money (narrow and broad), which clearly supports the quantity theory. The results show that money issuing authorities cannot obtain additional leverage by issuing more money without generating high inflationary pressure. The results also show the importance of financial sector innovations for velocity.

Yet another facet of research is the scientific evidence of yoga for the management of comorbid disorders associated neurological disorders.
RESOURCE-BASED COLLABORATIONS AND PERFORMANCE OF COURIER FIRMS NAIROBI CITY COUNTY, KENYA

The Communications Authority of Kenya (2016) documented a 14.3% drop in courier transactions from the year 2010 to 2015. Further, outgoing international transactions experienced a 20.6% decline. This downward trend has been attributed to development of communication technology and organisational competitiveness which has immensely affected the performance of the firms in this business portfolio. This has led most organisations to embrace certain corporate strategies and partnering with other organizations to strengthen their market positions and improve on performance. This study sought to establish the effect of resource-based collaborations on performance of courier firms in Nairobi City County. The study was anchored on the Resource Based View Theory. The study used a combination of descriptive and explanatory research designs. The target population consisted of 423 managers in 141 courier firms as at January 30th 2015(CAK, 2015) and the stratified sampling procedure was used to group the firms into strata using the licensing category. The study used mainly Primary data which was collected using self-administered questionnaire. Quantitative data was analyzed using both descriptive and inferential statistics. Descriptive statistics was used to summarize data while inferential statistics applied stepwise multiple regression analysis to test hypothesized relationships. Content analysis was also used for qualitative data. The analysis used SPSS Version 21 to aid data analysis. The study findings were that resource based collaborations had a positive significant influence on the performance of Courier firms in Nairobi City County. The study recommended that firms should re-think on configuration of resources in assessment of any collaborations the firm intended to engage itself in order to enhance performance. Key Words: Resource Based Collaboration, Organizations Performance, Courier Firms
The size of stable international environmental agreements in the case of stock pollution

Most of the literature on stability of International Environmental Agreements is essen- tially static and can therefore not identify changes in the size of the stable coalition in connection with changes in the stock of pollutants. This is a relevant issue because most global pollution problems are dynamic with stock externalities. This paper shows that the incentives for membership indeed change with changes in the stock of pollutants and that technology choice is an important factor when considering the consequences.
Preference and Predatory Potential of Chrysoperla carnea (Stephens) and Coccinella undecimpunctata Linnaeus on Phenacoccus solenopsis Tinsley: A New Threat to the Egyptian Economic Crops

The predatory potential and preference of Chrysoperla carnea (Stephens) larvae and both larvae and adult females of Coccinella undecimpunctata Linnaeus to the cotton mealybug, Phenacoccus solenopsis Tinsley and cotton aphid, Aphis gossypii Glover were investigated under laboratory conditions at Sakha Agricultural Research Station, Egypt. In no choice trails, 3 instar larvae of C. carnea were the most voracious feeder comparing to 1 and 2 instar larvae and consumed 673.3+ 6.38, 2756.3 + 20.10, 326.9 + 5.07 and 115.2 + 3.45 insects of aphid, 1, 2, and 3 instar nymphs of the mealybug, respectively. Similarly, 4 instar grubs of C. undecimpunctata proved to be the most voracious as compared to the younger instar grubs and devoured 112.4 + 1.63, 546.4 + 3.69, 174.1 + 1.07 and 40.2 + 1.22 individuals of aphid, 1, 2, and 3 instar nymphs of the mealybug, respectively. First instar nymphs of P. solenopsis were significantly the most consumed prey by both predators in the no choice feeding. Adult females of C. undecimpunctata exhibited more feeding potential than its larval stages on all the studied hosts. In free choice tests, A. gossypii was significantly the most preferred host for both predators comparing to the different instar nymphs of P. solenopsis. When C. carnea and C. undecimpunctata larvae were fed in free choice tests, the durations of their larval stages were significantly shorter than that of no choice feeding. The obtained results suggest that both predators could be successfully used as biological control agents for P. solenopsis management under the Egyptian conditions.
How can I improve provision for mathematics on a primary PGCE Initial Teacher Education programme in a context of national change

In this study, which was the focus for an MA dissertation, I focused on my own practice as subject leader for mathematics on a university-based PGCE Initial Teacher Education (ITE) programme and the ways in which I could examine, critique and ultimately change my practice in a time of change within the ITE sector. By using a mixed methods paradigm and an action research methodology, I explored elements of my practice and placed them in the context of recent developments in the sector, notably the introduction of the revised national curriculum in 2014 and the Carter review in 2015. In particular, I identified how the national context impacted on my own pedagogy in relation to trainees’ acquisition of mathematical subject knowledge, curriculum knowledge and pedagogical knowledge. The study demonstrates that by making small changes to ITE provision to implement national priorities, trainee satisfaction with the quality of their training experience can be improved.

Bifurcation of Lane Change and Control on Highway for Tractor-Semitrailer under Rainy Weather

A new method is proposed for analyzing the nonlinear dynamics and stability in lane changes on highways for tractor-semitrailer under rainy weather. Unlike most of the literature associated with a simulated linear dynamic model for tractor-semitrailers steady steering on dry road, a verified 5DOF mechanical model with nonlinear tire based on vehicle test was used in the lane change simulation on low adhesion coefficient road. According to Jacobian matrix eigenvalues of the vehicle model, bifurcations of steady steering and sinusoidal steering on highways under rainy weather were investigated using a numerical method. Furthermore, based on feedback linearization theory, taking the tractor yaw rate and joint angle as control objects, a feedback linearization controller combined with AFS and DYC was established. The numerical simulation results reveal that Hopf bifurcations are identified in steady and sinusoidal steering conditions, which translate into an oscillatory behavior leading to instability. And simulations of urgent step and single-lane change in high velocity show that the designed controller has good effects on eliminating bifurcations and improving lateral stability of tractor-semitrailer, during lane changing on highway under rainy weather. It is a valuable reference for safety design of tractor-semitrailers to improve the traffic safety with driver-vehicle-road closed-loop system.
Spline Dynamic Matrix: a Novel Representation of Dynamic Models

In the field of dynamic simulation, Finite Impulse Response (FIR), Step Response (SR) and discrete state-space (DSS) approaches are the most widespread model representations developed so far. Such representations, however, have some disadvantages, regarding simulation speed, computational load and fixed sampling. To cope with these restrictions, this work introduces a new model representation called Spline Dynamic Matrix (SDM), which combines the dynamic matrix model with the inputs parameterized by piecewise cubic splines. Such representation results in reduced matrixes, allowing variable spacing over simulation horizon. When compared with DSS representation, SDM behaves remarkably well, with mild deviations inherent to spline interpolation, keeping model adherence. SDM also presents itself as an effective way to implement model predictive controllers (MPC), being robust when compared to traditional formulation.
An Energy-Efficient Clustering Design Apply Security Method in Ubiquitous Sensor Networks

The ubiquitous sensor network consists of micro sensors with wireless communication capabilities. Compared to wired communication, wireless communication is more subject to eavesdropping as well as data variation and manipulation. Accordingly, there must be efforts to secure the information delivered over the sensor network. Providing security to the sensor network, however, requires additional energy consumption, which is an important issue since energy transformation is difficult to implement in a sensor network. This paper proposes a routing mechanism based on the energy-efficient cluster that features security functions capable of safely processing the data acquired from the sensor network. The proposed algorithm reduces energy consumption by fixing the clusters formed at the initial stage and using the pre-distribution scheme so that the cluster and node keys generated and exchanged at the initial stage are not re-generated or re-exchanged. Simulation experiments confirmed that the proposed approach reduces energy consumption compared to implementing security measures to the conventional cluster-based routing mechanism.
Speed Marking: Can intuitive skill replace conscious analysis?

This paper discusses the results of an experiment to determine the efficacy and accuracy of evaluating report-based assignments using intuitive cues versus conscious analysis. The experiment involves the evaluation of typewritten reports an average of four pages in length. A conscious analysis requiring twelve to fifteen minutes was performed on each report. The reports were also evaluated using an intuitive technique averaging three to four minutes each. After normalizing, the grades were compared. The data show a moderate correlation (r = .47) between the intuitive and analytical assessments. The paper concludes that the while the efficiency is attractive, the accuracy is inadequate for practical application. Future work could include an investigation to determine ways to “train” intuition by utilizing identifiable cues
Valorisation of Personal Health Records in Delivering Patient-centric Healthcare Services in a Resource Constrained Setting

Personal Health Records (PHRs) play a pivotal role in improving the delivery of patient-centric healthcare services. They have proven to be an indispensable tool in the self-management of personal health and wellbeing. Most high income countries have managed to implement PHRs in the provision of patient-centric healthcare services. However, resource constrained settings such as developing countries encounter a lot of challenges in utilizing PHRs in the delivery of patient-centric healthcare services. This paper therefore gives a comprehensive discussion on the comparative analysis of viability of the deployment of PHRs in both developed and resource constrained settings in providing patient-centric healthcare services. It is envisaged that the findings from this study will be the starting point towards the formulation of guidelines in deploying PHRs that will facilitate the provision of patient-centric healthcare services in a resource constrained environment. Furthermore, the study will provide valuable information for PHR designers, health providers and patients for patient-centric systems in a resource constrained setting.
