Published: May 2019

Hanna Fury Nur Ramdany, Heru Winarno in this paper explain that inductors have an important role in the field of electronics. Many values of capacitors and inductors whose values are difficult to translate, namely when capacitors and inductors are of low value and the color of the print is less clear , also considering the human read factor when an analog measuring instrument is used. From these problems, it is designed an inductance measuring instrument (L Meter) whose results can be directly displayed.The research method used in the manufacture of inductance meter measuring instruments is the literature method and laboratory tests using frequency variables generated or read by the oscillator circuit. The inductance measuring instrument designed in this researc is simple and meticulous measuring instrument that can be read and used by everyone. This digital inductance meter can be used to measure inductance - inductance with a level or a range of measurements between 20μH –100mH.The lower the inductor value measured, the higher the percentage error. So that the tools designed must be able to work well. The average error ratio of an inductance meter with a standard LCR meter is 6.5%. .

ALAT UKUR TDS (TOTAL DISSOLVED SOLID) AIR GARAM DENGAN RESISTIF SEBAGAI INDIKATOR
Authors: Dewa Aloisius Wisnu Lalita , Sasmoko Priyo 
Published: May 2019

Aloisius Wisnu Lalita Dewa, Priyo Sasmoko in this paper explain that, physical water quality can be identified in various ways, one of which is measuring the amount of solute called Total Dissolved Solid (TDS). This study aims to design and make a TDS solution by using two electrodes as sensors. These two electrodes flow alternating current and negative values alternately into water. Analog signal in the form of voltage is read by the microcontroller by converting it into a digital signal, then the microcontroller processes the data and displays the TDS value. Tests are carried out by measuring the same solution using TDS meters and salt water TDS. Testing starts from a solution of 175 ppm to 8500 ppm. Making solutions based on TDS meter factory production. The results of salt water TDS measurements showed that the measured tds values increased from 173 ppm to 8007 ppm. Error reading at 8500 ppm, this is because the reading distance of salt water TDS is only up to 8260 ppm. Keywords : TDS, conductivity, electroda, measurement device.ReferencesMalvino. 1995.

Addressing Construct Intensity in Entrepreneurship: Log-Transformed Guttman Scaling with Need for Achievement as Exemplar
Authors: Conejo Francisco J. , Young Clifford E. , Wooliscroft Ben , Parthasarathy Madhavan 
Published: May 2019

AbstractUnlike physical science, entrepreneurship lacks measurement units through which to quantify constructs properly. This study explores the viability of logarithmically transformed Guttman scaling (GS).Need for Achievement(nAch), a quintessential entrepreneurial feature, illustrates the technique’s application. A valid and reliable 10-item Guttman nAch scale is developed, its unidimensionality psychometrically confirmed. Compliant with measurement theory, the scale offers concatenatable units that quantify nAch intensity. GS is a viable complement to psychometric methods, a useful addition to entrepreneurship’s methodological repertoire. Researchers are encouraged to expand their view of entrepreneurial constructs. Also approaching them from an intensity perspective offers fertile ground for future inquiry.
Kavalactones from Kava (Piper methysticum) root extract as modulators of recombinant human glycine receptors
Authors: Hegazy Nada Hany , Breitinger Hans-Georg , Breitinger Ulrike 
Published: May 2019

Abstract
Roots of kava (Piper methysticum) plant are used in almost all Pacific Ocean cultures to prepare a drink with sedative, anesthetic and euphoric properties. One of the main active ingredients of the extract are kava lactones. Here, kava root CO2 extract and three kavalactones, DL-kavain, dihydrokavain and yangonin (isolated from whole extract by column chromatography) were tested for their inhibitory action on recombinant homomeric human α1 glycine receptors expressed in HEK293 cells. Kava CO2 root extract, as well as the individual components DL-kavain, dihydrokavain and yangonin inhibited glycine receptor activity in a dose-dependent manner. DL-kavain was the most potent inhibitor (IC50 = 0.077 ± 0.002 mm), followed by yangonin (IC50 = 0.31 ± 0.04 mm) and dihydrokavain (IC50 = 3.23 ± 0.10 mm) which were 4- and 40-fold less active than DL-kavain, respectively. Application of kava root extract did not reduce maximum currents, but increased EC50 of glycine. Simultaneous application of kava extract and strychnine showed additive inhibition, suggesting that binding of kavalactones and strychnine on the receptor is mutually exclusive. Overall, kavalactones exert a moderate inhibitory effect on the human α1 glycine receptor with DL-kavain being the most potent constituent.

Abstract

Background
To date, only a limited number of studies have evaluated the importance of abdominal subcutaneous fat thickness (ASFT) on gestational diabetes mellitus (GDM) screening. The aim of this study was to investigate the effectiveness of ASFT measurement during routine obstetric ultrasound performed between 24 and 28 weeks of gestation in predicting cases with GDM.

Methods
This prospective comparative study was conducted on 50 cases with GDM and 50 cases without GDM in the GDM screening program at 24–28 gestational weeks between January 2018 and May 2018. The most accurate ASFT cut-off point values were determined for the prediction of cases with GDM by performing receiver operator characteristic (ROC) curve analysis.

Results
The ASFT was higher in those with GDM compared to those without GDM (P < 0.05). For an ASFT cut-off point value of 18.1 mm for the prediction of cases with GDM, the sensitivity, specificity, negative and positive predictive values were 72.0%, 60.0%, 64.2% and 68.1%, respectively. The risk of GDM increased 3.86-fold in those with ASFT level >18.1 mm (P = 0.001).

Conclusion
The ASFT value measured by routine obstetric ultrasound performed at 24–28 weeks of gestation was found to be significantly higher in patients with GDM in comparison to those without GDM. However, further multi-centered and comprehensive prospective studies are required to better demonstrate this relationship.

Nasointestinal tube in mechanical ventilation patients is more advantageous
Authors: Ge Wu , Wei Wu , Shuang Pan , Yan-Xia Zheng , Ling Lv 
Published: May 2019

Abstract

Objective
To assess the effects of two different nutritional mode on the occurrence of ventilator-associated pneumonia (VAP) in patients on mechanical ventilation.

Methods
70 patients admitted to the ICU and under mechanical ventilation, were randomly divided into the nasointestinal tube group and nasogastric tube group. Patients from both groups received enteral nutrition, using the same nutritional agent, through intubation. The duration of stay in the ICU, duration of mechanical ventilation, incidence of VAP, nutritional state, and survival of the intestinal tract were compared between the two groups.

Results
The duration of stay in the ICU, duration of mechanical ventilation and incidence of VAP in the nasointestinal tube group was lower than that in the nasogastric tube group (P<0.05). There was an increase in the levels of prealbumin and transferrin in the nasointestinal tube group (P<0.05). However, there were no obvious difference in the nasogastric tube group (P<0.05). The incidence of abdominal distension, diarrhea, regurgitation, aspiration, and hyperglycemia in the nasointestinal tube group was much lower than that in the nasogastric tube group (P < 0.05).

Conclusion
This study showed that enteral nutrition delivery using a nasointestinal way can effectively reduce the incidence of VAP and improve the nutritional status of patients under mechanical ventilation.
Naming Rights
Authors: Baird Kingsley W. 
Published: May 2019

Abstract
This paper explores the rich and dynamic history of a physically modest hill called Pukeahu Mount Cook, located on the southern outer edges of the central business district in New Zealand’s capital city, Wellington. The hill was named »Pukeahu« by Māori who originally settled in the area and renamed »Mount Cook« by British colonists soon after their arrival in the nineteenth century. The story of Pukeahu Mount Cook is one of Māori habitation, tribal tensions and migrations, of conflict between Māori and Pākehā and the assertion of British colonial rule, and of the official narrative of New Zealand’s national identity forged through overseas wars and reinforced by associated remembrance practices. The hill’s two names, the ascendency of one over the other, and finally their »peaceful coexistence« are a reflection of changing cultural dynamics, a recognition of the nation’s founding bicultural principles and a process of restoration.

Published: May 2019

Abstract
While micronutrient malnutrition has become a major public health problem in developing countries, consumption of biofortified foods such as orange fleshed sweet potato has proved to be cost effective means of addressing vitamin A deficiency. This paper describes consumer preferences and willingness to pay for Orange fleshed Sweet potato (OFSP) juice based on a structured survey and taste tests administered to 946 participants (384 female and 562 male) chosen at random in Rwanda. Four juices types were tested: two popular brands of 100% pineapple juice, one 100%-OFSP juice, and one 80% OFSP- 20% pineapple juice blend. Consumers ranked different attributes of each juice such as aroma, taste, color, “right” amount of sugar, and aftertaste using a Likert scale (1 to 5). Heckman two-stage probit model was used to analyze willingness to pay and a multinomial logit model was used to analyze the determinants of juice choice. Gender of the consumer, juice buying frequency, aroma, the taste of the juice, and vitamin A knowledge were positively associated with willingness to pay and juice choice. Without nutritional information on OFSP juice, the willingness to pay for the standard juices were statistically higher; but with nutritional information, the willingness to pay and choice of OFSP juice was significantly improved. It is concluded that nutrition information is an important factor influencing the acceptance and willingness to pay for OFSP juice.
Cite This Economics Paper! It Is Time for the House of Cards to Fall Down
Authors: Payson Steven 
Published: May 2019

AbstractThis paper takes a fresh look at citation counts and publications in top-rank journals, which the academic economics profession uses to evaluate and promote its members. It first examines how and why citations are mentioned in an article, and what this implies about their counts. The discussion then examines how average citation counts to articles are used to rank journals, and the paper reviews the concerns that have been expressed about this practice. These concerns identify the large variance in citation counts among articles of the same journal, implying that those articles themselves must vary greatly in quality (Engemann and Wall 2009). To address these concerns, the paper proposes the classification of citations into three categories: Fodder Citations (for references that contribute only trivially to a paper), Relevant Citations (which substantively contribute to the paper, though the paper would remain roughly the same without them), and Essential Citations (which have a major influence). The paper argues that counts of citations by the last two categories offers greater credibility in the application of citation counts to evaluate economic literature. Finally, the paper provides an opportunity for economists to participate in a new project that solicits information on citations by these categories.
Verbal Symbols and Demonstrations Across Modalities
Authors: Ramchand Gillian 
Published: May 2019

AbstractIn this paper, I develop a new theory of the ingredients of semantic composition for the verb phrase, building on work in Ramchand (2018). I argue that the essential properties of this new approach make possible a new rapprochement between the theoretical analyses of symbolic verbal meaning across the visual and auditory modalities. The innovation of the new theory is that it partitions the verb phrase into a lower purely symbolic zone and a higher instantiational situation zone, mediated by the demonstrative act (cf. Davidson 2015, Henderson 2016). In the first part of the paper, I lay out the system, and then I show how it can be used to give a formal analysis of gestural and iconic elements in language. Along the way, I discuss the different ways in which iconicity in the two modalities plays out.
Hyperthermic intraperitoneal chemotherapy with cisplatin and mitomycin C for colorectal cancer peritoneal metastases: A systematic review of the literature
Authors: Pinto Amandine , Pocard Marc 
Published: May 2019

AbstractBackgroundThe randomized trial PRODIGE 7 failed to show the benefit of oxaliplatin hyperthermic intraperitoneal chemotherapy (HIPEC) in colorectal peritoneal metastasis treatment (CR PM). This systematic review focuses on the association of cisplatin (CDDP) with mitomycin C (MMC) in HIPEC in CR PM.ContentExperimental studies demonstrated that hyperthermia, in addition to CDDP ± MMC treatment, gradually improved the cytotoxic effect by increasing early apoptosis, eATP interaction, intracellular CDDP concentration (by 20%) and p73 expression. Recent studies with highly selected patients reported unusual prolonged survival with a median overall survival (OS) of approximately 60 months, with a HIPEC combination of CDDP (25 mg/m2/L) plus MMC (3.3 mg/m2/L) at a temperature of 41.5–42.5 °C for 60–90 min. Major complications occurred in less than 30% of patients with limited hematological toxicity (less than 15%). In addition, in a phase 2 trial, an adjuvant HIPEC benefit was demonstrated in colorectal cancer patients with high risk for peritoneal failure (5-year OS: 81.3% vs. 70% for the HIPEC group vs. the control group, respectively, p=0.047). After a recurrence, an iterative procedure permitted similar recurrence-free disease (13 vs. 13.7 months) with an acceptable morbidity (18.7% of severe complications).Summary and outlookThe combination of CDDP and MMC seems to be an interesting protocol as an alternative to high-dose and short-term oxaliplatin.
