Effect of Seed Layer on the Growth of ZnO Nanorods

To investigate the effect of seed layer on the growth of ZnO nanorods during hydrothermal synthesis, different types of sputter-deposited ZnO films were used. The changes in growth rate, diameter, density, and surface area of highly oriented ZnO nanorods on each seed layer were examined. The growth rate of ZnO nanorods has a strong relationship with the intensity of (0001) orientation. The density of nanorods per unit area is larger if the diameter of the nanorods is smaller. The total surface area of ZnO nanorods is determined by the growth rate and density per unit area. It was found that the morphology of the ZnO nanorods is strongly influenced by the thickness of the seed layer and the corresponding crystal size. A thinner ZnO seed layer provides a higher surface area of ZnO nanorods because of the smaller crystal size of the seed layer. The orientation of the ZnO seed layer significantly affects the crystallinity of the nanorods.
Twitter as an Across-Border Social Media Platform: Who is Participating?

We propose a cross-cultural study of participation in across-border Twitter conversations, inspired by writer and speaker Siyanda Mohutsiwa’s views on Twitter as a tool for fostering social pan-Africanism among African youth. We study prior work on Twitter use and non-use, the role of Twitter in organizing groups of people, and social media use related to the interaction of different identities. We use this work to ground an exploratory cross-cultural study that would compare the tweets from Mohutsiwa’s #ifafricawasabar hashtag with tweets from a similar hashtag in India and the United States. We propose our overall research and methodological questions with the goal of formulating best practices for comparative analyses of Twitter data.
Clinical presentation of patients who developed narcolepsy type 1 after the influenza A (H1N1) epidemic and vaccination campaign in Norway -Health related quality of life, psychiatric symptoms and medical comorbidities Sebjørg

Objective: Cross-sectional studies show a lower health-related quality of life (HRQoL) in individuals with narcolepsy. We aimed to describe changes in HRQoL after two years of multidisciplinary follow-up in a cohort of mainly post-H1N1 vaccination narcolepsy type-1 (NT1) patients in Norway. Methods: Prospective-cohort study. Narcolepsy diagnosis was based on the International Classification of Sleep Disorders (third edition). Psychiatric comorbidity was assessed using the Achenbach System of Empirically Based Assessment (ASEBA). HRQoL was evaluated with the Pediatric Quality of Life Inventory (PedsQLTM Generic Core Scales 4.0) at baseline and follow-up. Mean follow-up timewas 20.7 (2.7) months. Results: Thirtyonepatients (18 females)withNT1,meanage14.6 (SD1⁄44.8)yearsansweredquestionnairesat baseline and follow-up. On a group level, the PedsQLTotal Health Summary score significantly improved by a mean of 5.9 (95%CI 1⁄4 0.4, 11.9), p 1⁄4 0.038; this was mainly driven by improvements in the Physical Health Summary score by 9.8 (3.0, 16.5) points, p 1⁄4 0.006 and the School Functioning Scale score by 7.5 (1.0, 13.9) points p1⁄4 0.025. The Total ASEBA scorewas correlatedwith PedsQLTotal Health Summary score at baseline, but not with changes in HRQoL. Sodium oxybate (Xyrem®) treatment at follow up was positively associated with changes in PedsQL Total Health Summary score, after adjusting for age and gender, p 1⁄4 0.027. Conclusion: HRQoL in NT1 patients improved after two years of follow-up. The use of sodium oxybate (Xyrem®) at follow-up was associated with increases in HRQoL. Psychiatric comorbidity was correlated with HRQoL at baseline but did not predict changes in HRQoL at follow-up. © 2018 Elsevier B.V. All rights reserved.
Virtual Machines for Dynamic Languages

A common approach to execute dynamic languages is inside a virtual machine (VM), usually implemented in a low level system language like C. Such VMs have to support the often complex syntax and semantics of the dynamic languages they are hosting. Additionally, some properties of dynamic language code can only be inferred at runtime making the optimization of code execution another challenging task. Therefore, it is hardly possible to provide general purpose implementations that support a large range of different dynamic languages. Furthermore, many commonly used dynamic languages such as Python or Javascript are still evolving which means that their VMs have to adapt constantly. This implies that it is necessary to write and maintain a sufficiently elaborated code base for every single dynamic language. As a result, there is a significant development overhead when creating efficient, well optimized, and feature complete dynamic language VMs which often stands in contrast to time and resource limitations. Tack-ling this problem, research has focused on techniques to lower the development effort required to create VMs while increasing their maintainability. Simultaneously, emphasis was placed on optimization strategies that enable efficient code execution despite dynamically inferred runtime properties. The goal of this work is to give an overview over techniques for writing dynamic language VMs proposed during the last 20 years and to evaluate them.
School Physical Safety and Social Relationships as Correlates of Teacher Productivity in Public Secondary Schools in Akwa-Ibom State of Nigeria

The study examined school physical safety and social relationships as correlates of teacher productivity in public secondary schools in Akwa-Ibom State of Nigeria. Two (2) research questions and 2 hypotheses guided the study. The design of the study was correlational, with the population as the 268 public secondary schools in the state. These schools have 268 principals, from which 203 (76%) were selected as sample, using the simple random sampling technique. The instruments of the study were the validated 18 item Physical Safety and Social Relationship Scale and the 11 item Teacher Productivity Scale (TPS), designed by the researchers with reliabilities of 0.86 and 0.88, respectively. Pearson Product Moment Correlation Co-efficient was used in answering the research questions while the Pearson r.values were converted to p.values and used in testing the hypotheses, at 0.05 level of significance. The results of the study show positive high correlation between school physical safety and social environment and teacher productivity. The findings also establishes significant correlation between school physical safety, social relationships and teacher productivity.
KNOWLEDGE ASPECT OF INTERROGATIVE SPEECH OF INDONESIAN LANGUAGE TEACHERS IN TEACHING PROCESSES

This study aims knowledge aspect of interrogative speech of Indonesian language teachers. The objectwas interrogative speechs of Indonesian language teachers. The data was analyzed by content analysis techniques. Based on data analysis reaveals four levels of knowledge aspect in interrogative speech of Indonesian language teachers: level I-Low Order Convergent, level II-High Order Convergent, level III-Low Order Divergent, and level IV-High Order Divergent. The result reaveals that interrogative speech of Indonesian language teachers level I was most frequently used. It’s mean, the teachers used many interrogative speech level I or low knowledge aspect in teaching processes.There are three contents of the interrogative speech act of Indonesian teachers in teaching processes: conceptual question, empirical question, and value question. Of the three contents of the question, the most frequently used is conceptual question, because in teaching the teachers ask more about the concept of a particular material.
Milk yield and genomewide expression profiling in the mammary gland of beef primiparous cows in response to the dietary management during the pre- and postweaning periods1

Accelerated growth programs during prepubertal periods have been promoted to advance the first calving of beef heifers. The objectives of the present study were to evaluate nutrition-induced changes on first lactation milk yield and composition and on gene expression of the mammary gland in Parda de Montaña primiparous cows. Female calves (n = 16) were involved in a 2 × 2 factorial experiment. In the preweaning period (PRE-W; 0–6 mo), female calves were either fed a creep feed supplement (Creep) or fed only their dam’s milk (Control). In the postweaning period (POST-W; 6–15 mo), heifers received either a high-energy diet (91.7 MJ/d) or a moderate-energy diet (79.3 MJ/d). All the heifers were managed together from breeding (15 mo) to the end of their first lactation (32 mo). Animal performance; milk production and quantity during the first lactation; plasma glucose, IGF-I, and leptin concentrations; and RNA samples from the mammary gland at the end of the first lactation of the primiparous cows (32 mo) were analyzed. The BW and ADG of the primiparous cow during its first lactation were not different among treatments; however, creep feeding during PRE-W reduced milk production (P < 0.01), milk CP, crude fat, lactose, nonfat solids, and casein content throughout lactation and increased somatic cell count in the third (P < 0.05) and fourth month of lactation (P < 0.10). The energy level during the POST-W had no effect on milk production and quality. Gene expression in the mammary gland was affected by the diet in the PRE-W and POST-W, with the PRE-W diet having the greatest impact. During the PRE-W, creep feeding resulted in upregulation of genes related to immune response and chemokine activity, suggesting that these animals might be in a compromised immune status. Therefore, this strategy would not be recommendable; meanwhile, increasing the energy level in the diet during the POST-W would be recommendable, because it had no deleterious effects on milk yield and composition.
Plasma functionalization of PCL nanofibers changes

18 The surface properties of electrospun scaffolds can greatly influence protein adsorption and thus 19 strongly dictate cell-material interactions. In this study, we aim to investigate possible correlations 20 between the surface properties of argon, nitrogen and ammonia/helium plasma-functionalized 21 polycaprolactone (PCL) nanofibers (NFs) and their cellular interactions by examining the protein 22 corona patterns of the plasma-treated NFs as well as the cell membrane proteins involved in cell 23 proliferation. As a result of the performed plasma treatments, PCL NFs morphology was preserved 24 while wettability was improved profoundly after all treatments because of the incorporation of 25 polar surface groups. Depending on the discharge gas, different types of groups are incorporated 26 which influenced the resultant cell-material interactions. Argon plasma-functionalized PCL NFs, 27 only enriched by oxygen-containing functional groups, were found to show the best cell-material 28 interactions, followed by N2 and He/NH3 plasma-treated samples. SDS-PAGE and LC-MS clearly 29 indicated an increased protein retention compared to non-treated PCL NFs. The nine proteins best 30 retained on plasma-treated NF are important mediators of extracellular matrix interaction, 31 illustrating the importance thereof for cell proliferation and viability of cells. Finally, 92 proteins 32 that can be used to differentiate the different plasma treatments are clustered and subjected to a 33 gene ontology study, illustrating the importance of keratinization and extracellular matrix 34
Critical success factors for mHealth services in rural Ghana

Ghana is a developing country in Sub Saharan Africa (SSA) with a population of more than 30 million [1], 44% living in rural areas [2] and a low health worker density [3]. The ‘doctor-to-population’ ratio is 0.12 and as low as 0.04 per 1000 people in the Upper East making healthcare not easily accessible. Although the number of communicable diseases like malaria has decreased in recent years, there is a substantial increase in non-communicable diseases like hypertension and diabetes [1]. In the last decades, innovative information and communication technologies have offered solutions in several fields including healthcare, not only in developed countries. In 2010, Ghana defined an eHealth strategy [4] and several mHealth projects have been initiated [5]. mHealth, or “mobile health”, is a component of eHealth being the use of information and communication technologies (ICT) for health. The World Health Organisation (WHO) defined mHealth as “the medical and public health practice supported by mobile devices, such as mobile phones, patient monitoring devices, personal digital assistants (PDAs) and other wireless devices” [6]. Given the shortage of medical professionals, the need for improving health care delivery and a mobile phone ownership of 80% mobile health services are very promising, especially for people in rural and remote areas [7]. However, transferring successful pilots to scaleable and sustainable solutions is a real challenge. This paper presents the lessons learnt from a selection of successful mHealth services developed and deployed in Ghana: MDNET, mPedigree and MoTeCH. Furthermore, relevant insights of recent research into the opportunities and barriers for mobile solutions are discussed. This paper highlights the most critical success factors for the implementation of mobile services in rural and remote areas in Ghana that could possibly be applied to other developing countries in a similar setting.
Effects of Supplemental Feed with Different Levels of Dietary Metabolizable Energy on Growth Performance and Carcass Characteristics of Grazing Naturalized Swan Geese (Anser cygnoides)

Simple Summary Swan geese are becoming a very popular economic wildfowl in China, however, there lacks nutrient requirement guidelines for farmed Swan geese. This study evaluated the effects of supplemental feeding of dietary metabolizable energy (ME) level [9.5, 11.5, and 13.5 MJ/kg of dry matter (DM)] on growth and carcass characteristics of grazing Swan geese. The results showed that growth performance and body-size measurements (except shank length) were greatly improved by offering supplemental feeds to grazing geese, with no difference among supplemental feeding treatments. As DM intake (DMI) decreased with increasing dietary ME from day 29 to 56; meanwhile, slaughter, semi-eviscerated, eviscerated, and thigh muscle yield decreased with increasing dietary ME on day 56, and a well-balanced supplemental diet with ME of 9.5 MJ/kg of DM was recommended to improve growth and meat production of grazing Swan geese. Abstract Grazing Swan geese (Anser cygnoides) have good meat quality but grow slowly. This study aimed to study whether supplemental feeding could improve growth performance of grazing Swan geese and investigate a suitable dietary metabolizable energy (ME) level of supplemental diet for grazing Swan geese. Naturalized healthy male Swan geese (n = 144; 42 ± 2.0 days and 1.21 ± 0.17 kg) were randomly allocated into 4 groups and grazed on pasture alone (control, CON) or offered supplemental diets with ME of 9.5, 11.5, or 13.5 MJ/kg of DM after grazing. Growth performance and body-size measurements (including bone development) were lower (p < 0.05) in CON versus supplemented geese, as well as slaughter measurements on days 28 and 56. The DM intake linearly decreased (p < 0.01) with increasing dietary ME from day 29 to 56. Slaughter, semi-eviscerated, eviscerated, and thigh muscle yield linearly (p < 0.01) decreased with increasing dietary ME on day 56. Lightness (L*) and yellowness (b*) for breast and thigh muscle on days 28 and 56, and breast muscle shear force on day 56, were lower (p < 0.01) in supplemented versus CON geese. In conclusion, supplemental feeding improved growth performance and carcass characteristics of grazing Swan geese, and supplemental feed with ME of 9.5 MJ/kg of DM could be offered to improve growth and meat quality of grazing Swan geese.
A Coding Scheme for Conversational Style Classiﬁcation in Online Microtasking

To improve satisfaction and engagement of workers in on-line crowdsourcing marketplaces, recent research in HCI has proposed the use of conversational interfaces to support the execution of a variety of tasks. Prior works in linguistics have shown that conversational styles have an important impact on human communication. Little is known about whether and how conversational styles of agents can be leveraged to improve outcomes in conversational micro-tasking. To this end, we propose a coding scheme to classify the conversational styles crowd workers and empirically observe how conversational styles of workers relate to work outcomes. Results show that crowd workers with a highly involved conversational style produced signiﬁcantly higher quality results, exhibited a higher user engagement and perceived less cognitive task load in comparison to those in a highly considerate style. Our ﬁndings can have important implications on task design in microtask crowdsourcing.
Chatbot with Touch and Graphics: An Interaction of Users for Emotional Expression and Turn-taking

Use of chatbots for emotional exchange is recently increasing in various domains. However, as existing chatbots have been considered in terms of natural language processing techniques for interaction with text-based chatting, chatbot interaction with users is lacking in terms of considering the emotions of users and managing turn-taking in conversation. This paper suggests an interaction technique having touch interactions with graphic interfaces (TwG) to solve these problems. In the system, users send their emotions and manage turn-taking through TwG technique. We conducted a Wizard of Oz study to evaluate user experience on emotional expression and turn-taking with TwG technique. Results showed that TwG interaction improved emotional expression compared to a traditional text-based chatbot interaction. Furthermore, the results showed that TwG positively affects natural turn-taking of the conversation.
The Effect of Yoga Exercise on Reducing Blood Pressure among Elderly with Hypertension : A systematic review

Hypertension is the most commonly encountered problems experienced by the elderly with sometimes unknown cause. One effort to lower blood pressure in the elderly is to provide yoga exercises, where yoga exercises can stimulate endorphin hormone expenditure. The purpose of review was to determine the effectiveness of yoga exercises for decreasing blood pressure in the elderly. An initial search for articles was done on Google Scholar and PubMed. Studies obtained about exercise therapy for hypertension elderly have 4,560 articles / journals but only 5 articles meet the search criteria. According to the search results, yoga exercises can reduce blood pressure in the elderly. Besides, it is also very important to be applied as a non-pharmacological therapy for the elderly who have a medical history of hypertension. It is expected that health professionals can recommend this as a therapy for lowering blood pressure in the elderly.
PHOTOCHEMICAL REACTION PATHWAYS OF ETHYLENE

Conical intersections are a common feature in most nondiabatic singlet photoreactions. For ethylene, several S1–S0 conical intersections could be located by CASSCF calculations. The energetically lowest one is different from the one determined by Ohmine [J. Chem. Phys. 83, 2348 (1985)]; its geometry suggests that cis–trans isomerization and a [1,2]hydrogen shift occur via the same funnel. © 1998 John Wiley & Sons, Inc. Int J Quant Chem 70: 1023–1028, 1998
INTRATUMORAL DNA-BASED GENE TRANSFER AS AN EFFICIENT DELIVERY APPROACH TO COMBINE CHECKPOINT-INHIBITING ANTIBODIES WITH INTERLEUKIN 12

Background The clinical benefit of CTLA-4 blockade to cancer patients has been well established. However, the promising antitumor activity shown by anti-CTLA-4 monoclonal antibodies (mAb) has been limited by the occurrence of immune-mediated adverse reactions, especially when CTLA-4 inhibition is used in combination with anti-PD-1 therapy. These dose-limiting toxicities restrict the therapeutic use of CTLA-4 blockade. To overcome these limitations, we have developed a potent anti-CTLA-4 antibody that is selectively active in the tumor microenvironment (TME). This antibody is engineered with an Fc region for enhanced Fc g R binding and peptides that mask antigen-binding regions. The masking peptides are designed to be selectively cleaved and released by proteases that are more active in the TME, resulting in restoration of full activity of the antibody in the TME.
The raging daycare debates

Politicians often use “the children” to justify policy choices. And certainly, nowhere but in the daycare debates are “the children” more of a handy excuse. But on Parliament Hill, the daycare debates are as much about economics and simple ideological politics as softwood lumber or tax cuts. In this environment, studies are used toward political ends. Studies should inform the debate—but how can parents—and politicians—know what constitutes good research?
On a simple model for describing convection of the rotating fluid: Integrability, bifurcations and global dynamics

The Glukhovsky-Dolzhansky (GD) model arises naturally from geophysical science, which describes rotating fluid convection inside the ellipsoid. This work aims to provide some new insights into the GD model. (i) We first show that, under some conditions there are homothetic transformations which covert the GD model into other similar quadric physical models, therefore, our results on the GD model can be naturally applied to the investigation of these models. (ii) We propose a complete classification of Darboux polynomials and exponent factors for the GD model, which implies that the GD model has no polynomial, rational, or Darboux first integrals. In addition, some integrable cases of the GD model are also given when the physical parameters are allowed to be non-positive. (iii) The existence of global attractor is proved. The stability and local bifurcations of all co-dimension one and two are investigated. Particularly, we show that the GD model undergoes two dynamical transitions as the Rayleigh number increases. (iv) To understand the asymptotic behavior of the orbits for the GD model, we use the Poincaré compactification method to study its dynamical behavior at infinity. More precisely, we prove that the phase portraits of the GD model at infinity consist of an infinite sequence of periodic solutions and two heteroclinic loops. Our results may help us better understand the complex and rich dynamics of rotating fluid convection.
