A verified model of laser direct metal deposition using an analytical enthalpy balance method

Analytical modelling of a quasi-stationary laser melt pool without mass addition can be achieved using relatively simple moving surface heat flux solutions. However, including mass addition from a coaxial powder stream alters the laser flux and energy and mass flow pathways and often leads to the problem being modelled using numerical methods. The model described in this paper combines an analytical beam attenuation model to account for beam powder interaction above the melt pool with series of standard solutions for a moving Gaussian heat source to calculate melt pool size and substrate isotherms. A negative enthalpy method is used to compensate for the mass addition to the melt pool. The model is verified using a variety of methods and can predict powder stream mass and temperature distribution at the substrate and final melt pool shape in three dimensions from the major laser direct metal deposition process variables. The model highlights the role of beam-powder interaction in the process.

The Effect of Audit Committe on Internet Financial Reporting: Study from Financial Industry in Indonesia

: The purpose of this study was to determine the effect of the audit committee on the internet financial reporting (IFR). Audit committees are measured by the number of members, educational background, professional background, and number of audit committee meetings. The measurement of financial report quality uses the full disclosure of companies reporting. This study uses data of financial institutions listed on the IDX in 2017. The total population of companies that meet the criteria is 95 companies with the number of observations is 110 companies. Data were analyzed using multiple regression analysis. The results showed that the number of members, educational background, and the number of audit committee meetings did not affect the IFR. It only frequencies of audit committee meeting affect the IFR. The selection of the audit committee is based on the professional background of the audit committee which has an impact on the selection of public accountant firm (KAP).
Development of System Continuance Models for Assessing among Local E-Government in Indonesia

: This study reports how to combine technology acceptance and use models based on expectations and confirmations in the information system success model to objectively assess the continuance of local e-government based on the organizational perspective and perspective of users in Indonesia. The developed model is arranged in 11 variables and 48 indicators. Pathways of influence between variables are presented by 16 links. However, this study does have some limitations. With regard to the level of use, there is no fully mandatory use of the system, and not all UTAUT2 variables and the possibility of a moderator are integrated with the model. Other studies used various assumptions, methods, and different understandings can present different propositions. In addition, limitations can help to further study, especially the validity of the proposed model. Future research can explore additional expansion variables and moderators, so that in the new model between variables can be made more explicit relationships.
Doing business in a deals world: the doubly false premise of rules reform

ABSTRACT The Doing Business reports have evoked an intense policy debate about whether countries should simplify regulatory rules or make them more stringent. We argue that doing business in developing countries is based on deals struck between firms and the state, rather than rules. We show that there is a weak relationship between rules and deals, and at low levels of state capability, more stringent rules leading to less compliance, rather than more. We provide a diagnostic approach to rules reform where the appropriate reform depend on the level of stringency of the rules, and the level of its state capability.
Impact of Metacognitive Awareness on Academic Adjustment and Academic Outcome of the Students

The study aimed to examine the impacts of metacognition and gender on the academic adjustment and academic outcome of the participants. Five hundred twenty two undergraduate and postgraduate male (M = 20.53, SD = 2.06) and female (M = 20.47, SD = 2.00) students served as the participants in the study. Metacognitive Awareness Inventory (Schraw & Dennison, 1994) and Academic Adjustment Scale (Anderson et al., 2016) were employed to measure the metacognitive awareness and academic adjustment of the participants. The results of the study exhibited no gender differences in metacognition and academic adjustment except academic achievement and academic outcome of the male and female participants. The results of the study also evinced that scores on declarative knowledge, procedural knowledge, conditional knowledge, planning, information management, monitoring, debugging, evaluation components of metacognition and overall metacognitive awareness demonstrated positive correlations with the academic achievements, overall academic adjustment and academic outcome. Contrarily, the scores of planning and evaluation were found to be negatively correlated with the scores of academic lifestyle of the male, female and all the participants. Lastly, the results of the study demonstrated that the scores on declarative knowledge, procedural knowledge, conditional knowledge, planning, information management, monitoring, debugging, evaluation components of metacognition and overall metacognitive awareness accounted for significant variance in the scores of academic life style, academic achievements, overall academic adjustment and academic outcome. The results of the study have significant implications of for researchers, academicians, laymen, counselors and school psychologists. The limitations and future directions for researchers have also been discussed.

Heavy metal concentrations in tissues of Egeria radiata (bivalvia: tellinacea) from creeks in Burutu area of Delta state, Nigeria.

Levels of heavy metal concentrations in tissues of Egeria radiata from Obotebe and Gbekobor Creeks in Burutu Local Government Area were investigated. E. radiata samples were collected fortnightly for 12 months in 2008. The soft tissues of E. radiata were extracted, weighed and dried in oven for three days at 60 0 C. Ten grams of the dried samples were homogenized and digested before analysis using the atomic absorption spectrophotometer (AAS) to determine levels of heavy metals such as (copper, lead, manganese, cadmium, mercury, chromium and nickel). The results obtained showed that tissues of E. radiata from the creeks were contaminated with heavy metals. The mean concentrations of heavy metals in tissues of E. radiata followed an increasing sequence of Hg < Cd < Cr < Mn < Pb < Cu < Ni. Heavy metal concentrations in tissues of E. radiata were higher but were not significant in the dry season than in the rainy season. Levels of heavy metals in tissues of E. radiata were found to be below the FAO/WHO acceptable limits of heavy metal pollution in fishes and shell fish. Mean levels of lead (Pb), manganese (Mn) and Cadmium (Cd) were found to be higher than world standard but not significant. Nickel were significantly lower than world standard. There is a need for constant monitoring of levels of heavy metals in the area of study in order to forestall any significant rise in their levels.
Experimental investigation of the effects of hydrogen addition on the dynamics of turbulent premixed flames

With an ever increasing need for the reduction of carbon and nitrogen based emissions, gas turbine technology has evolved over the years. Lean burning (i.e. high air to fuel ratio) has proven to be an effective method in reducing the nitrous oxide emissions. However, these flames are susceptible to combustion oscillations that could lead to excessive heat transfer, oscillatory thermal and mechanical stresses and flame blow-off or flashback. The addition of hydrogen fuel to turbulent flames has been studied in the past and been reported to have reduced combustion oscillations and nitrous oxide formation, however, there are studies in literature that show combustion oscillations triggered by the addition of hydrogen. This project aimed to further investigate the effects of local hydrogen addition on the dynamics of turbulent lean premixed flames in a model gas turbine combustor. The flames were subjected to controlled reactant mass flow oscillations (created by acoustic speakers) that led to flame surface roll-up, thus causing heat release perturbations (i.e. combustion oscillations). Under these conditions hydrogen fuel was locally added into the flow to study the effects on the response of the flame. A secondary objective was to develop a laser technique for imaging the laser induced fluorescence of atomic hydrogen in turbulent flames. While earlier studies had only focused on laminar flames, this project concentrated on imaging large sections of turbulent premixed flames which were subjected to acoustic forcing. The results showed that the local addition of hydrogen reduced the heat release oscillations of the flame under certain operating conditions. The change in the response of the flame was due to the alteration of the flame surface area. While there were benefits of reducing heat release oscillations, the addition of hydrogen to the flame had a negative impact on the nitrous oxide exhaust emissions.
Equilibrative Nucleoside Transporters Mediate the Import of Nicotinamide Riboside and Nicotinic Acid Riboside into Human Cells

Nicotinamide riboside (NR), a new form of vitamin B3, is an effective precursor of nicotinamide adenine dinucleotide (NAD+) in human and animal cells. The introduction of NR into the body effectively increases the level of intracellular NAD+ and thereby restores physiological functions that are weakened or lost in experimental models of aging and various pathologies. Despite the active use of NR in applied biomedicine, the mechanism of its transport into mammalian cells is currently not understood. In this study, we used overexpression of proteins in HEK293 cells, and metabolite detection by NMR, to show that extracellular NR can be imported into cells by members of the equilibrative nucleoside transporter (ENT) family ENT1, ENT2, and ENT4. After being imported into cells, NR is readily metabolized resulting in Nam generation. Moreover, the same ENT-dependent mechanism can be used to import the deamidated form of NR, nicotinic acid riboside (NAR). However, NAR uptake into HEK293 cells required the stimulation of its active utilization in the cytosol such as phosphorylation by NR kinase. On the other hand, we did not detect any NR uptake mediated by the concentrative nucleoside transporters (CNT) CNT1, CNT2, or CNT3, while overexpression of CNT3, but not CNT1 or CNT2, moderately stimulated NAR utilization by HEK293 cells.
TP preparation in open and distance learning: Lecturer and student views

For Teaching Practice (TP) to be productive adequate preparation of student teachers is necessary. In Open and Distance learning both practical and theoretical activities can be employed in the preparation of student teachers for TP. At the time students in intake 10 who were studying the Diploma in Education Primary (DIPED) at Zimbabwe Open University (ZOU) went to seek for places where they could do TP some school heads were reluctant to offer them places as they questioned the thoroughness with which the students had been prepared for TP in comparison with students at conventional colleges. A study was conducted to determine challenges faced in preparing students for TP and the ways in which TP preparation for DIPED students was perceived as adequate or otherwise by students and lecturers. Data were generated from participants in the ZOU Midlands region only via open-ended questionnaires. The study established that students had adequate and relevant theoretical input on educational foundations and activities linked to TP such as mentoring, whose content was covered in pre-TP modules and tutorials. The one-month home based observation organised for students, peer and micro teaching were viewed as efficient in preparing students for TP although some loopholes were opined in the use of these strategies. Nonetheless, practice in the use of modern technology in the classroom and production and use of media were viewed as inadequately covered for purposes of preparing students for TP. The study recommends the development of student teacher skills in integrating ICT in their TP, inter alia.
Prejudice towards Host Culture and Acculturative Stress: Studies on Internal Migrants in Indonesia

: Many researchers on prejudice have focused on minority ethnic students at the receiving end of prejudice by the host cultures. This study focuses on the prejudice of minority ethnic students towards the host culture and its contribution to acculturative stress. It also attempts to analyse the influence of perceived language proficiency (c.q. Javanese language) and gender on acculturative stress. Participants comprised 69 undergraduate students studying in a state university and coming from various ethnicities other than Javanese that was considered the host culture in Surakarta. Results indicated that prejudice to the host cultures was a predictor of acculturative stress. Meanwhile, perceived language proficiency and gender didn’t have significant effect on acculturative stress. Implications, limitations and future research direction are discussed.
A Novel Multiprotein Bridging Factor 1-Like Protein Induces Cyst Wall Protein Gene Expression and Cyst Differentiation in Giardia lamblia

The capacity to synthesize a protective cyst wall is critical for infectivity of Giardia lamblia. It is of interest to know the mechanism of coordinated synthesis of three cyst wall proteins (CWPs) during encystation, a differentiation process. Multiprotein bridging factor 1 (MBF1) gene family is a group of transcription coactivators that bridge various transcription factors. They are involved in cell growth and differentiation in yeast and animals, or in stress response in fungi and plants. We asked whether Giardia has MBF1-like genes and whether their products influence gene expression. BLAST searches of the Giardia genome database identified one gene encoding a putative MBF1 protein with a helix-turn-helix domain. We found that it can specifically bind to the AT-rich initiator promoters of the encystation-induced cwp1-3 and myb2 genes. MBF1 localized to cell nuclei and cytoplasm with higher expression during encystation. In addition, overexpression of MBF1 induced cwp1-3 and myb2 gene expression and cyst generation. Mutation of the helixes in the helix-turn-helix domain reduced cwp1-3 and myb2 gene expression and cyst generation. Chromatin immunoprecipitation assays confirmed the binding of MBF1 to the promoters with its binding sites in vivo. We also found that MBF1 can interact with E2F1, Pax2, WRKY, and Myb2 transcription factors that coordinately up-regulate the cwp genes during encystation. Using a CRISPR/Cas9 system for targeted disruption of mbf1 gene, we found a downregulation of cwp1-3 and myb2 genes and decrease of cyst generation. Our results suggest that MBF1 is functionally conserved and positively regulates Giardia cyst differentiation.
Establishment a diagnostic strategy of pheochromocytoma by plasma free metanephrines determined by liquid chromatography-tandem mass spectrometry

Objective To set up reference intervals of plasma free metanephrine (MN) and normetanephrine (NMN) by liquid chromatography-tandem mass spectrometry (LC-MS/MS) and diagnostic strategies of pheochromocytoma. Methods 255 healthy people were recruited to set up reference intervals.110 patients with pheochromocytoma were also enrolled, in addition to 1 262 subjects taken as disease control group and 500 subjects taken as health control group. Positive rates of plasma free MN and NMN were compared among different groups. Diagnostic strategies were designed according to reference intervals and cut-off value with optimal specificity determined by receiver operating characteristic (ROC) curve. Results The reference intervals of MN and NMN are <64.97 pg/ml and <185.83 pg/ml, respectively. Significant differences in the level of MN and NMN were found between not only pheochromocytoma group and disease control group (Z=-17.410, P=0.000; Z=-17.278, P=0.000), but also pheochromocytoma group and health control group (Z=-16.434, P=0.000; Z=-16.439, P=0.000). We establish diagnostic strategy A for either of MN and NMN above the upper limit of the reference range and B for either of MN and NMN above specific diagnostic cutoff value to rule in or rule out the diagnosis of pheochromocytoma. Conclusion The reference intervals of plasma free MN and NMN by LC-MS/MS and diagnostic strategies of pheochromocytoma. Key words: Liquid chromatography-tandem mass spectrometry; Metanephrine; Normetanephrine; Pheochromocytoma
RNA Sequencing Data: Hitchhiker's Guide to Expression Analysis

Gene expression is the fundamental level at which the results of various genetic and regulatory programs are observable. The measurement of transcriptome-wide gene expression has convincingly switched from microarrays to sequencing in a matter of years. RNA sequencing (RNA-seq) provides a quantitative and open system for profiling transcriptional outcomes on a large scale and therefore facilitates a large diversity of applications, including basic science studies, but also agricultural or clinical situations. In the past 10 years or so, much has been learned about the characteristics of the RNA-seq data sets, as well as the performance of the myriad of methods developed. In this review, we give an overview of the developments in RNA-seq data analysis, including experimental design, with an explicit focus on the quantification of gene expression and statistical approachesfor differential expression. We also highlight emerging data types, such as single-cell RNA-seq and gene expression profiling using long-read technologies.
Studies on freshness of refrigerated poultry meat.

The research aimed at assessing the quality of poultry meat stored for 10 days under the refrigeration conditions (temperature of +1.7 °C and moisture of 76%) through a series of tests on pH value, easily hydrolysable nitrogen content and hydrogen sulphide. The acidity of pectoral muscle increased from the first day (5.87) by the 10-day of storage (6.38), aspect also applies to muscular thighs, the limits of variation ranged from 6.07 to 6.48. Also easily hydrolysable nitrogen content has ascended in both pectoral muscles (from 17.36 mg/100g on the first day, at 28.48 mg/100g in 10-a day), and in the thigh (17.58 mg/100g of fresh meat and 28.01 mg/100g to the 10 days’ storage). Our results concerning the value of indicators which define the state of fresh poultry meat stored under the refrigeration conditions showed, that food may be considered suitable for public consumption until the 6 th day of storage.
