PEMODELAN REAKTOR ABSORPSI MENGGUNAKAN ABSORBEN LIMBAH LAS KARBID UNTUK MENGOLAH CO2
Authors: Dewi Kania , Law Steffani
Published: May 2018

Model transfer massa dalam reaktor absorpsi semi batch untuk mengolah CO2 menggunakan limbah las karbid telah dikembangkan berdasarkan hukum kesetimbangan massa, teori transfer massa dan laju reaksi. Simulasi model reaktor dilakukan dengan solver ODE45 program MATLAB R2009a dengan pendekatan Metode Runge-Kutta orde 4. Asumsi yang digunakan dalam pemodelan ini adalah reaktor bekerja pada kondisi steady state, kedua fasa berada pada suhu 25°C, kecepatan pengadukan serta bubbler diabaikan, dan orde reaksi merupakan pseudo orde satu. Model divalidasi dengan menggunakan hasil penelitian laboratorium absorpsi CO2 oleh limbah las karbid dalam reaktor semi batch dengan konsentrasi inlet sebesar 18%. Absorpsi CO2 oleh limbah las karbid yang mengandung Ca(OH)2 terutama terjadi pada liquid-bulk sehingga perpindahan massa akan terjadi lebih besar di liquid-bulk dibanding dengan perpindahan massa di gas-liquid film. Model matematis yang dikembangkan dengan solusi numerik menggunakan metode Runge Kutta orde 4 secara umum dapat menggambarkan pola yang hampir sama dengan hasil penelitian laboratoirum, walaupun digunakan nilai  konstanta reaksi hasil penelitian yang jauh lebih lambat daripada nilai konstanta reaksi teoritis.

Published: May 2018

The aim of the research was to determine the copper deposit volume on winter oilseed rape in three development phase (according to the BBCH scale: 12, 14 and 16). The experiment was performed in triplicate at the spraying speed of 0.86 m s-1. Two working fluids were used: foliar fertilizer Mikrovit Copper 80 and a nanocopper preparation, at the dose of 160 g Cu ha-1. The deposition treatment of the plants was conducted in the spraying chamber ‘Aporo1’ at two pressures (0.20 and 0.28 MPa), using two different types of flat fan nozzles. The dried rape plants were mineralized, and then, in order to determine the deposit, the Cu element concentration was measured using the spectrometer. The largest deposit of copper was obtained using the foliar fertilizer Mikrovit Copper 80 and using a double flat fan nozzle DF 120-02. The statistical analysis of the results of the study showed a significant effect of the type of liquid used on the value of copper deposit on winter oilseed rape plants.

Lääkemääräys on laadittava sähköisesti 1.1.2017 alkaen. Laissa määriteltyjen poikkeustapausten perusteella laaditussa kirjallisessa ja puhelinlääkemääräyksessä on perusteltava, miksi sitä ei ole annettu sähköisesti. Valtakunnallisen toiminnallisen muutoksen myötä on mahdollista selvittää ensimmäisen kerran lääkemääräysten kokonaismäärä Suomessa. Tutkimusaineistona ovat reseptikeskukseen tallennetut potilastietojärjestelmissä ja Kelaimessa laaditut sähköiset lääkemääräykset sekä apteekeissa tallennetut (sähköistetyt) kirjalliset, puhelin- ja erityislupavalmisteiden lääkemääräykset tutkimusjaksolla 1.1.–30.11.2017. Reseptikeskukseen tallennettiin tutkimusjaksolla 29,477 (100 %) milj. sähköistä lääkemääräystä, joista 96,6 % oli laadittu potilastietojärjestelmissä ja 1,0 % Kelaimella. Apteekeissa sähköistettiin 0,375 (1,3 %) milj. lääkemääräystä, joista 0,246 (0,8 %) milj. oli kirjallisia ja 0,122 (0,4 %) milj. puhelinlääkemääräyksiä. Apteekeissa sähköistetyistä lääkemääräyksistä yli puolet oli kirjallisia lääkemääräyksiä, jotka oli laadittu teknisen häiriön perusteella. Tutkimuksessa selvitettiin ensimmäisen kerran Suomessa lääkemääräysten kokonaismäärää vuoden 2017 yhdentoista kuukauden tietojen perusteella. Valtakunnallisessa seurannassa ilmeni päivittäin teknisiä häiriöitä, joiden perusteella laadittiin kirjallisia ja puhelinlääkemääräyksiä.

Authors: Mejia Alzate Mario Andres , Melo Trujillo Joel David , Padilha Feltrin Antonio , Sánchez Zuleta Carmen Cecilia , Fernández Gutiérrez Juan Pablo
Published: May 2018

In recent years, the population growth in urban areas of Latin American cities has resulted in an increase in demand for electricity in a dispersed manner, bringing challenges to the planning of distribution systems to supply this demand. In addition, incentives for the installation of distributed generation make it necessary to carry out analyzes with a spatial perspective to determine the places of impact in the electricity distribution networks. Geographic information systems are computational tools that allow the processing of data with geographic reference. These systems can collaborate in the visualization of the socioeconomic characteristics and the variables distributed in the zone of study, being able to provide information to the distribution planners. This work shows computational tools that will help distribution utilities, using techniques available in geographic information systems to characterize the local factors in concession zone of the distribution utilities.

Published: May 2018

Aims

SCN5A is a disease-causing gene associated with familial dilated cardiomyopathy (FDC). We examined the possible association between a common polymorphism in the SCN5A gene (c.1673A>G-p.H558R; rs1805124) and the risk of dilated cardiomyopathy (DCM) occurrence.

Methods

We genotyped 185 DCM cases (familial DCM, idiopathic DCM and postischemic DCM) and 251 controls for the p.H558R polymorphism in the SCN5A gene, to test the association of the molecular epidemiology of the individuals with the presence/absence of various types of DCM.

Results

Our results showed that the rs1805124 polymorphism was significantly associated with DCM, and the association was more significant in patients with FDC; furthermore, in these individuals, the less frequent GG genotype was associated with a 7.39-fold increased risk of disease [95% confidence interval (95% CI) = 2.88–18.96; P < 0.0001] compared with the AA genotype. Moreover, logistic regression analysis showed that GG carriers had a higher risk of DCM than AA + AG carriers (odds ratio = 5.45, 95% CI = 2.23–13.35; P < 0.001). No association was observed between the rs1805124 and DCM risk in postischemic DCM patients.

Conclusion

Our study demonstrates an association between familial DCM and the rs1805124 polymorphism in the SCN5A gene, which may unravel additional genetic predisposition to the development of a multifactorial disease as DCM.

Published: May 2018

One of the ways to maintain the security of data transfer over the network is to encrypt the data before sending it, for the purpose of increasing data privacy and its importance, Steganography, is used to hide encrypted data in various documents, such as sheets of MS Excel sheets.

The purpose of the encrypted data packaging during transport from one place to another is,  to convince an unauthorized person, nothing has not been added to the transport data. The art of concealment is embodied hidden words to be passed confidentially within a file without influence on the properties of the file and this can't be anyone's hand is to know that there is confidential data encapsulated by transport data. Whereas, the Microsoft Excel file size being used to hide data remains constant in spite of the file containing the confidential data.

The secret for the survival of file size unchanged despite the addition of encrypted data, is that confidential data is added to the value of the color of the font used in the cells, leading to the font color change slightly.

 Previous research used the Excel file to hide data in different ways, but the data masking and packaging by changing the color content writing is what distinguishes our research and make it alone in this area.
Vehicle Intersection Collision Monitoring Algorithm Based on VANETs and Uncertain Trajectory
Authors: Ding Hongwei , Wu Hao , Dong Lan , Li Zejun
Published: May 2018

In order to ensure driving safely, the driving safety assistance system must be able to aware of potential collision accidents in advance, especially significant for the intersection where traffic accidents occur more frequently. Considering that VANETs is one of the most important applications for improving the safety of driving, furthermore, vehicles have an inherent uncertainty of location because the exact position of a moving object is known, with certainty, only at the time of an update on position information. In order to reduce the accident rate at intersection and combine the driving characteristics of vehicles at traffic intersections, a vehicle intersection collision monitoring algorithm based on VANETs and uncertain trajectory is proposed. The algorithm is divided into two categories: uncertain trajectory prediction algorithm and vehicle collision monitoring algorithm. The proposed approach provides approximate answers to the user at the user’s required level of accuracy while achieving near-optimal communication and computational costs. Finally, extensive experiments were conducted to show the efficiency and efficacy of the proposed approach.

Field methods to assess pectoral muscle mass in moulting geese
Authors: Nyeland Jens , Fox Anthony D. , Kahlert Johnny , Therkildsen Ole R.
Published: May 2018

In this paper, we report two new simple field methods to assess changes in pectoral muscle mass in live moulting geese. In the first method, transverse chest profiles of Canada geese Branta canadensis and greylag geese Anser anser were recorded using soldering wire. This standard measure of the chest angle showed a highly significant relationship with actual pectoral muscle mass. Chest angle measures showed a highly significant polynomial correlation with an index of moult stage, i.e. length of the ninth primary (p9). This indicated an initial slight decline in pectoral muscle mass as p9 length increased, followed by an increase in muscle mass in preparation for regaining the ability to fly. In the second method, visual pectoral profile scores from 0 (thin pectoral muscles concave) to 3 (convex bulky) recorded at distances using telescope or binoculars also proved to be useful as a field measure of pectoral muscle mass in moulting geese. Hence, the first method provides a non‐consumptive means of predicting pectoral muscle mass in moulting geese without the need to dissect birds, and the second method enables field prediction of muscle mass in moulting geese without resort to capture of birds.
A comparison of age estimation methods for the saiga antelope Saiga tatarica
Authors: Lundervold Monica , Langvatn Rolf , Milner‐Gulland E.J.
Published: May 2018

Age estimation is particularly crucial for the conservation of the saiga antelope Saiga tatarica, but modern laboratory methods for aging have not previously been applied to this species. There is an urgent need for evaluation of the techniques that could be used for age estimation in order that long‐term ecological data sets can be correctly interpreted and conservation advice given. We evaluated the repeatability, practical feasibility and comparability of three techniques for age estimation of saiga antelopes; the tooth sectioning technique (TS), the tooth eruption and wear technique (TEW), and a visual aging technique routinely used in field studies. We found that TS and TEW gave repeatable results, and agreed well. The visual method underestimated the age of males compared to laboratory methods. It assigned animals consistently to the age class of at least one year old, but less consistently to the age class less than one year old. Although studies of known‐age animals are needed to evaluate precision and accuracy of these methods, we suggest that either TS or TEW would be suitable for aging saiga antelopes, with the choice being determined by practicalities such as the availability of the necessary expertise and equipment.
Feral pigs in tropical lowland rainforest of northeastern Australia: ecology, zoonoses and management
Authors: Heise‐Pavlov Peter M. , Heise‐Pavlov Sigrid R.
Published: May 2018

Feral pigs are well established in the lowland tropical forests of northeastern Queensland, Australia. Circumstantial evidence, e.g. the presence of a Melanesian tick, an exotic nematode and a dominant coat colour other than black, indicates that they do not originate from escaped domestic animals as feral pigs throughout other parts of Australia. It is likely that the ancestral population was established from animals originating from islands to the north and northwest of Australia, i.e. pigs domesticated from naturally occurring wild pigs in Indonesia and southeastern Asia. Pigs in lowland rainforests show relatively stable populations with a high reproductive potential in age classes 4–7. Seasonally there are negative interactions between residents and pigs. Pigs not only damage gardens and fruit orchards due to their rooting, they are also important vectors of zoonoses. Feral pigs are carriers of 11 Leptospirosis serovars, some of which are important zoonoses, e.g. L. australia, L. hardjo and L. zanoni. They also have a high burden of parasites. Lice Hematopinus suis and thorny headed worm Macracanthorhynchus hirudinaceous have been more frequently found in females than in males, whereas males seem to be more susceptible to ticks Ambylomma cyprium cyprium. The infection with lungworms Metastrongylus sp. is higher in younger pigs than older ones indicating that lungworms represent a major mortality factor of young pigs. In contrast, kidney worm Stephanurus dentatus and thorny headed worm is present at all ages. Leptospirosis, lung worm and kidneyworm are known causes of infertility and/or mortality in pigs and can be assumed to contribute to the lower than expected population density in this environment.
Variation in ranging and activity behaviour of European wild boar Sus scrofa in Sweden
Authors: Lemel Jonas , Truvé Johan , Söderberg Bo
Published: May 2018

The present wild boar Sus scrofa population in Sweden mainly originates from animals that have escaped from enclosures. At some locations wild boars have evidently been released deliberately. Whatever their origin, rapid increases in both number and distribution of free‐ranging wild boars have occurred. As wild boars are considered exotic in the Swedish fauna, sportsmen very often provide supplemental food in varying degrees, partly to facilitate and secure hunting possibilities, partly to keep wild boars out of farmed crops. In this paper we describe wild boar activity behaviour and intend to show how wild boar adjust their activity behaviour under different ambient conditions. The aim of our study was to increase the knowledge of managers to improve hunting effectivity and risk assessment concerning crop damage. The wild boars were, almost without exceptions, active during night. The mean time for an activity bout was 7.2 hours and the wild boars in the study area were only to a minor degree adjusting their activity bout to the prevailing night length. However, the hour of sunset seemed to be the cue which triggered the onset of activity bouts. The mean distance that the wild boars travelled during activity bouts was 7.2 km and the estimated mean activity range was 104.4 ha. The mean effort when roaming the activity range was 110.9 m/ha. A substantial variance was typical for all activity variables. For activity distance, 72% of the variation was explained by adding wind speed, season, minimum temperature and snow cover to our model. Significant effects of minimum temperature, snow cover and an interaction between activity time and minimum temperature explained 42% of the variation in activity range. The variation in relative air humidity explained 41% of the time active during an activity bout.
Birth rate and offspring survival in a free‐ranging wild boar Sus scrofa population
Authors: Náhlik András , Sándor Gyula
Published: May 2018

We estimated birth rates in wild boar Sus scrofa by counting embryos in the uterus of females killed in individual or drive hunts. Counting corpora lutea in the ovaries gave information on embryo:corpus luteum rate, which can be useful for estimating birth rates in early stages of pregnancy. Birth rates were estimated separately for the different age groups. Age was estimated by means of teeth wear. Survival was estimated by direct observations counting the piglet:female ratio in matrilineal groups. The method is suitable for assessing summer survival only, as 8–9 months after birth, matrilineal groups begin to disintegrate. Average estimated birth rate was 6.7 ± 2.1 (N = 51).We found a positive linear relationship between conception rate and age of female, conception rate and body mass, and conception rate and body length, respectively. In late stages of pregnancy, embryo:corpus luteum rate proved to be 0.83 ± 0.15. Recruitment of piglets to the female population was low; more than half of the piglets had perished by the end of September.

Authors: McKinney Richard A. , Glatt Sarah M. , Williams Scott R.
Published: May 2018

We developed models to estimate the soft tissue content of benthic marine invertebrates that are prey for aquatic wildlife. Allometric regression models of tissue wet weight with shell length for 10 species of benthic invertebrates had r2 values ranging from 0.29 for hermit crabs Pagurus longicarpus to 0.98 for green crabs Carcinus maenas. As a class, bivalves had the highest r2 values (0.84) and crustaceans the lowest (0.48). Energy and nutrient content of soft tissue is also presented for the 10 benthic species. The energy content was lowest in crabs, and ranged within 2.20–4.71 kcal g‐1 dry weight. Fat content was highly variable (range: 3.5–16.0%), and protein content ranged within 43.1–68.1% and was highest for shrimp Palaemonetes pugio. Comparison between classes of organisms of the amount of soft tissue per unit shell length showed that crustaceans yield five times more soft tissue per unit shell length than bivalves, and four times more than gastropods. The models we present use simple measures, such as the length of shell or wet weight of the entire animal, to quantitatively estimate the amount of available soft tissue in benthic prey that are usually consumed in total (with shell and soft tissue intact) but for which only the soft tissue is used for nutritional gain. This information can be combined with energy and nutrient content data to calculate energy or nutrient based carrying capacities that can help assess available resources for shorebirds, waterfowl and marine mammals.
Great bustard Otis tarda habitat selection in relation to agricultural use in southern Portugal
Authors: Moreira Francisco , Morgado Rui , Arthur Stephen
Published: May 2018

We investigated habitat selection patterns of the great bustard Otis tarda in a dynamic agricultural landscape in southern Portugal. Combining data from 26 bustard counts with habitat mapping, we used resource selection functions to characterise habitat selection in two areas with different agricultural uses. Selection patterns were compared among areas, seasons (breeding, post‐breeding and winter), and flock types (male, female and mixed) during the breeding season. Seasonal differences in selection patterns generally parallelled changes in estimated food availability. Stubbles (i.e. recently harvested fields) and stream margins were preferentially selected by all bustards during the post‐breeding period, whereas cereal and fallow fields were selected during winter. During the breeding season, males selected fallow fields more than other habitat types, whereas females selected cereal fields. Habitat selection seemed to be influenced by habitat availability, with birds showing stronger selection for preferred habitats in the areas where they were less available. Great bustards used different habitat types throughout the agricultural year, and we recommend that habitat management promotes a rotational crop system that includes cereal and fallow fields.

Published: May 2018

The recolonising wolf Canis lupus population has created conflicts in Scandinavia, and it will eventually be necessary to control wolf numbers if the population continues to grow. One mechanism for this is hunting. Under what circumstances will the Swedish public support hunting of wolves? We examined this question for the general public and for three stakeholder groups: all hunters, the public living in areas with wolf populations and hunters living in wolf population areas. A majority of all four groups found it acceptable to hunt wolves to reduce the risk of livestock depredation (53–91%), and if wolves had been coming into populated areas (54–86%). However, about one fifth of the Swedish public was neutral to any justification, so an extreme or a well‐publicised event could alter the current levels of support. The majority in all groups did not support wolf hunting merely because people were afraid of them (22–46%), or because wolves compete with humans for game (11–45%). A majority of all hunters found wolf hunting to be justified if wolves were a threat to dogs in the area, but the majority of the general public even in the wolf population areas did not find this to be appropriate justification. Our study shows the importance of surveying stakeholder groups as well as the general public to develop sound and acceptable conservation and management plans for rebounding populations of large carnivores such as wolves.
Culturally Important Objects as Signs of Cretan Protolinear Script
Authors: Kenanidis Ioannis K. , Papakitsos Evangelos C.
Published: May 2018

This paper presents seven “syllabograms” of the Cretan Protolinear script (signs used for Consonant-Vowel [CV] syllables). This presentation is conducted following the theory of the Cretan Protolinear (CP) script as the one that all the Aegean scripts evolved from, including Linear A, Cretan Hieroglyphics and Linear B. The seven syllabograms of this particular set depict inanimate objects or constructions that were very common or important in everyday life, economy and religion. It is also demonstrated that the phonetic value of each syllabogram corresponds to the Sumerian name of the object depicted by the syllabogram, in a conservative dialect. Thus, more light is shed on the linguistic ancestry of the Aegean scripts, the practice followed for their creation, and, indirectly, on some cultural aspects of the Minoan Civilization.
Population Growth and Life Expectancy in Nigeria: Issues and Further Considerations
Authors: POPOOLA Oladayo Timothy
Published: May 2018

This study empirically investigates the effects of population growth on average life expectancy in Nigeria taking into account the explicit role of healthy citizens in economic development as well as other control variables not considered in prior studies. Predicted on country-specific regression and Granger Causality test using time series data between 1986 and 2015, the findings reveal that rising population growth have positive and insignificantly impacts life expectancy; but 1% decrease in fertility rate and population of 65-and-above dependency ratio could positively stimulates an improvement in longevity by 5.84, and 81.5 respectively in Nigeria. Furthermore, the granger causality test shows that population growth could granger cause low life expectancy in Nigeria at least at 10% level of significant. The findings therefore make a case for strengthening efforts towards reducing both fertility rate and age 65 and above dependency ratio with priority given to the welfare of ages 65 and above population in Nigeria.

Scientific knowledge as well as experiment keeps on growing every day.  Experiments flourished in the seventeenth century. Previously, information about world development was obtained by connecting the roles of prominent epistemology. Experimentation is defined as a planned program for restoring hypotheses by providing empirical evidence to people. Science is a process of seeking the truth. Activities in finding the truth involves a series of scientific method including experiment. The development of physics history is divided into five periods. Period one is indicated by the absence of systematic and independent experiment. In period two, experimental methods had been accountable, and well accepted as a scientific issue. In period three, (investigations developed more rapidly when classical physics development began to be foundation of current famous quantum physics). Period four which is called The Old Quantum Mechanics is indicated by the invention of microscopic phenomena. Period five is well known by the emergence of new quantum mechanics theory.

Published: May 2018

This article summarizes results of a unique, 10-year collaboration between the New Mexico Medical Board and the University of New Mexico School of Medicine's mini-sabbatical program for physicians considering relicensure and reentry into practice. The Board assesses all physicians wishing to reenter active practice to determine their background and needs, and the medical school's office of continuing medical education then evaluates candidates for their retraining goals, coursework, and faculty involvement. Progress is measured weekly, at course completion, and three months thereafter. Of the 27 physicians referred from the Board between 2004 and 2014, five were judged to require more extensive residency retraining and four received administrative medical licenses. Twelve of the 18 eligible candidates elected to enter the medical school's mini-sabbatical program. The median training was four weeks (160 AMA PRA Category 1 Credits™). Their education did not interfere with the learning of medical students and residents. All except one demonstrated acceptable core clinical skills to permit granting of an unrestricted medical license. Eleven completed the program and were successful in attaining employment in New Mexico. This collaboration permitted a determination for a physician about the extent of retraining before relicensure. The mini-sabbatical program was successful in returning eligible physicians to practice in our state.

Published: May 2018

This paper discusses the information needs of regulators in the face of increasing globalization in medical education and practice, the history of information resources cataloging the world's medical education institutions, and the development of a tool that can fill an information gap concerning where and how physicians around the world are educated — the World Directory of Medical Schools. The World Directory was developed to meet the needs of medical regulators and other stakeholders who rely on specific data about medical schools and their educational programs. Its data model captures information about schools and programs as separate entities, allowing for greater flexibility and utility in the areas of regulation and workforce research.
