Atualmente o hábito de se alimentar fora do lar tem sido cada vez mais incorporado ao dia a dia dos brasileiros. Sabe-se que a alimentação saudável proporciona qualidade de vida, pois com isso, é necessário que se aprenda a administrar as horas do dia a dia de forma organizada a fim de realizar as tarefas cotidianas com otimização do tempo. Para tal, além de um esforço pessoal, há a necessidade de se buscar recursos tecnológicos que ajudem a “ganhar” tempo a cada dia. Como forma de aliar à tecnologia a sustentabilidade, este trabalho visa elaborar uma solução lógica para um software com funções de monitoramento para irrigação de uma horta caseira, a fim de proporcionar uma vida com costumes mais saudáveis dentro de um tempo administrado pela própria pessoa. Neste contexto, o presente estudo tem como o objetivo a elaboração de um protótipo para instalação de um pequeno motor que permitirá bombear água para a irrigação das mudas; temporizador e interpretação de comandos lógicos que permitam controlar uma irrigação à distância; modelagem de dados das funções a serem implementadas. Foi possível montar um circuito compatível com módulos Arduíno, possibilitando automatizar o processo de irrigação de uma horta caseira, juntamente com o desenvolvimento de uma lógica que monitorasse e corrigisse a umidade necessária do solo da horta para a produção de mudas de hortaliças em uma residência. A solução utiliza sensores de monitoramento de umidade do solo para medir e acionar a irrigação quando necessário.

Published: February 2020

Different mix of clients visit primary health care (PHC) facilities, and the quality of services is critical even in rural communities. The study objective was to determine the relationship between socio-demographic characteristics and client satisfaction with the quality of PHC services in Calabar Municipality, Cross River State, Nigeria. Specifically to describe aspects of the health facilities that affect client satisfaction; determine the health-care providers’ attitude that influences client satisfaction; and determine the socio-demographic characteristics that influence client satisfaction with PHC services. A cross-sectional survey was adopted. Ten PHCs and 500 clients utilizing services in PHC centers in Calabar Municipality were randomly selected. Clients overall satisfaction with PHC services was high (80.8%). Divorced clients were less (75.0%) satisfied than the singles and the married counterparts (81%), respectively. Clients that were more literate as well as those with higher income were less satisfied, 68.0% and 50.0%, respectively, compared to the less educated and lower-income clients, 92.0% and 85.0% respectively. These differences in satisfaction were statistically significant (P = 0.001). Hence, it was shown that client characteristics such as income and literacy level show a significant negative relationship with the clients satisfaction with the quality of PHC services in Calabar Municipality.
Evaluation of microbial flora of the external surface of housefly (Muscadomestica) in Umuahia Metropolis, Abia State, Southeast Nigeria
Authors: Nwankwo E. O. , Ekemezie C. L. , Adeyemo S.
Published: February 2020

Objective:

Houseflies are vectors responsible for the mechanical transmission of pathogens acquired from feeding in feces and decayed organic debris. Human consumption of such food without warming could lead to gastroenteritis, a major public health problem. The aim of this research was to evaluate the range of microbial pathogens associated with the external surfaces of fly vectors and to determine the antibiotic susceptibility pattern of the bacterial pathogens.

Materials and Methods:

A total of 150 houseflies were collected with a sterile net from different parts of Umuahia, Abia State. Their external surfaces were screened for bacteria, fungi, and protozoan parasites in the Microbiology Laboratory of Michael Okpara University of Agriculture, Umudike by standard microbiological procedures. Antibiotic sensitivity pattern of bacterial isolates was carried out by disc diffusion method.

Results:

The most frequently observed microorganisms wereEscherichiacoli(22.9%),Klebsiellaspp. (16.6%),Staphylococcusaureus(14.6%),Aspergillusspp. (28.3%), Mucor spp. (21.7%),Entamoebahistolytica(32.7%), andEndolimaxnana(30.9%). Houseflies from broken sewage had the highest total viable counts and frequency of bacteria, fungi, and parasites. Bacterial isolates from houseflies gotten from health-care facilities showed higher levels of multiple drug resistance to ampicillin and cotrimoxazole.

Conclusion:

In this study, pathogenic microorganisms were recovered from the external surface of houseflies, the vectoral agents of mechanical transfer of microbial contaminants to exposed food. Most of the microorganisms observed in this study are known pathogens that can cause gastroenteritis which is a public health concern.

Published: February 2020

Objective:

There is different perception of HIV/AIDS counselling fatique among counsellors of patients. This descriptive study assessed perceived HIV/AIDS counseling fatigue among HIV/AIDS counselors in Calabar, Nigeria.

Materials and Methods:

A total of 90 counselors were assessed using a 35-item questionnaire measuring a variety of counseling activities. Fatigue was ranked on a 5-point Likert-type scale. The counseling fatigue was categorized in five subscales: accessibility of clients for HIV Counseling and Testing (HCT), explains and facilitates, monitoring and follow through, trusting relationships, policies in counseling activities, and burnout responses.

Results:

The results showed that counselors’ perceptions on fatigue were mostly on accessibility of clients for HCT (Mean = 72.50, standard deviation [SD] = 6.124) with statistical significance of Chi-square calculated = 161.419, df = 5; P < 0.001, monitoring and follow through activities (mean = 71.80, SD = 11.23, Chi-square calculated = 31.223; df = 4; P < 0.001), and policies in counseling activities (mean = 66.0 SD = 9.62, (Chi-square calculated = 11.906, df = 6; P < 0.05). Explain and facilitate statistically and significantly correlated with age (r = 0.610, P = 0.000) and years of experience (r = 0.695, P = 0.000). Burnout responses were also statistically significant (Chi-square calculated = 144.000; df = 7; P < 0.001).

Conclusion:

Findings show HCT counseling activities generally cause fatigue for counselors, however, explain and facilitate counseling activities correlated with age (20–29 years) and years of experience (1–2 years) as these were found to be more fatigued among the participants. The years of experience correlation could be attributed to lack of formal HCT counseling training reported by 20 (20%). Further research is needed to explore counselors’ perceptions of HIV/AIDS counseling fatigue in different cultures.

Anti-arthritic evaluation of Eclipta alba in a murine model Freund’s adjuvant provoked arthritis
Authors: Tirupathi Rao Y R K V  , Gopal Rao K  , Satishchandra A
Published: February 2020

Eclipta alba (E.alba) is a medicinal plant with wide range of biological action encompassing antioxidant and anti-inflammatory. However, its anti arthritic activity is not reported till date.  So we have evaluated the anti-arthritic property of E.alba methanolic extract in arthritis induced rats. The rats were made arthritic by single intradermal injection of complete freunds adjuvant (CFA) and E.alba (200 and 400mg/kg) were administered for 28 days. The assessment of arthritis was done by evaluating body weight, paw volume and alteration in hematological parameters (WBC, RBC, Hb and ESR). Further, to evaluate oxidative stress, malondialdehyde (MDA), a marker of lipid peroxidation and antioxidants (SOD, CAT, GPx and GSH) were measured. The arthritis induced rats showed significant decrease in body weight, elevated paw oedema, and changes in blood parameters. Treatment with E.alba significantly reduced the arthritic symptoms by its anti-inflammatory effect. Further, arthritic rats displayed elevated MDA and decreased antioxidant levels and treatment with E.alba inhibited the lipid peroxidation and restored the antioxidants to normal. The present study reveals that Eclipta alba showed effective anti-arthritic activity through its antioxidant and anti-inflammatory property.  Further the anti-arthritic activity of E. alba might be due to the presence of various phytochemicals such as flavanoids and polyphenols.

Uniformity or Unilateralism in the Law of Carriage of Goods by Sea?
Authors: Myburgh Paul
Published: February 2020

The ideal of international uniformity has always been regarded as particularly important to maritime law. However, over the past decade or so, the uniformity of the law of international carriage of goods by sea has increasingly been undermined by the unilateral adoption by maritime jurisdictions of "hybrid carriage regimes" which depart from the established international uniform rules.In this article Paul Myburgh argues that this trend towards adoption of divergent carriage regimes is highly problematic, not merely because of their detrimental effects on international uniformity and the coherence of maritime law and international transport law in general, but also because of more fundamental concerns about the validity of these regimes at international law, the practical conflict of laws problems that that they will generate, and their distorting effects on multimodal transport. The article concludes with some suggestions for future reform in this area.
Pure Ideology: the "Ownership Split" of Power Companies in the 1998 Electricity Reforms
Authors: Kalderimis Daniel
Published: February 2020

In April 1998 the New Zealand Government announced a reform package for the electricity industry. This package was designed to create the competition promised since deregulation first began in 1987. The 1998 reforms had two main aspects: first, the split of the Electricity Corporation of New Zealand (ECNZ), New Zealand's dominant state-owned enterprise (SOE) generator, into three competitive units; second, a rule business (the ownership split) that local power companies could not own both a lines business (the local distribution wires) and a generation or retail.The ownership split caused a revolution in the industry. Effectively, small community-owned companies were forced to sell their retail and generation businesses to larger companies or to the State, in the form of the ECNZ "babies". The Government believed that the ownership split would facilitate retail competition and deliver lower domestic power prices. This article asks whether the Government was right – whether the ownership split was necessary, or able, to reduce domestic power prices. It concludes that the ownership split was a staggering mistake. The Government's reasoning was based on inconclusive evidence, inadequate research, and contained major logical flaws. The Government rejected unanimous policy advice warning against the split. Since the split, average domestic power prices have risen by almost four per cent. A major factor is the demise of community-owned supply companies which had offered unique advantages to consumers.The root of this disaster was ideological bias. The Government did not understand the electricity industry but treated it as an abstract economic construct. This article documents the way in which ideology led the Government to wreak havoc on an industry in order to cure problems which did not exist.
"We are all Here to Stay"; Addressing Aboriginal Title Claims after Delgamuukw v British Columbia
Authors: Yurkowski Rachel A
Published: February 2020

This article outlines how the Canadian courts dealt with the interface between aboriginal title and common law notions of property throughout the various Delgamuukw decisions.  Through examination of the different judgments in the case, at different judicial levels, the article traverses issues around the source of aboriginal title, and subsequent limitations on the content of aboriginal title which arise from that.  The article concludes that the unique concept of aboriginal title cannot be interpreted within the paradigm of the common law.  The article further concludes that courts are the wrong forum for adjudicating aboriginal claims.

Authors: Armstrong Daniel
Published: February 2020

This article comprehensively catalogues and critiques the differences between the mortgagee remedies of entry into possession and receivership. In particular, the article looks at differences in how rights, duties, powers and liabilities of a mortgagor in possession as opposed to a receiver affect the choice of remedy. The author concludes that recent changes to the law in New Zealand have undermined the traditional advantages of receivership, and that equity is currently re-emphasising the rights of mortgagors.

This article is a book review of Bryan Gilling The Ombudsman in New Zealand (Dunmore Press in association with the Historical Branch, Department of Internal Affairs, Palmerston North, 1998) (190 pages, $29.95). Gilling's book provides an important account of the evolution of the New Zealand ombudsman providing an accessible and careful analysis of its first thirty years, which contained periods of both government stability as well as radical changes in the government's structure, the economy, the class structure, the status of minority groups and foreign relations. Vosburgh states that the book stands as a study of institutionalism and evolution of government structures, and praises Gilling for containing a comprehensive account with a compact and sharp focus.
A Short History of Western Legal Theory by J M Kelly
Authors: Petersson Sandra
Published: February 2020

This article is a book review of J M Kelly A Short History of Western Legal Theory (reprint, Clarendon Press, Oxford, 1997) (466 + xvi pages, $75). Kelly's aim was to make the reader see jurisprudence in its historical setting, something that Petersson agrees was done well. The book discusses the history of Western legal theory through the ages, tracing key themes including Theory of the State, Validity of Law, Rule of Law, Nature and Purpose of Law, Natural Law, Equality, Property, Equity, Criminal Law and Punishment, and International Law. Petersson notes that Kelly's work is notably non-Anglocentric. However, Petersson comments on Kelly's failure to treat positivism as its own separate conception of law, as well as Kelly's omission of feminist legal theories.

Authors: Rohmaniah Siti Alfiatur , Chandra Novita Eka
Published: February 2020

The price of life insurance premiums for each person depends on the probability of death, not only based on age and gender as offered by an Indonesian insurance company.  The purpose of this study is to determine premium prices on underwriting factors and frailty factors using Generalized Linear Mixed Models (GLMM). GLMM is used for modeling a combination of fixed effect heterogeneity (underwriting factors) and random effects (frailty factors) between individuals. The data used longitudinal data about underwriting factors that have Binomial distribution are taken from the Health and Retirement Study and processed using R software. Because the data used by survey data within an interval of two years, so the probability of death is obtained for an interval the next two years. Underwriting factors that have a significant effect on the probability of death are age, alcoholic status, heart disease, and diabetes. As a result, is obtained the probability of death models each individual to determine life insurance premium prices. The premium price of each individual is different because depends on underwriting factors and frailty. If frailty is positive, it means that a person level of vulnerability when experiencing the risk of death is greater than negative frailty.

Three-dimensional matrices of biodegradable polymers are promising materials for regenerative medicine. They are widely used in restoring the integrity and functions of tissues and organs using bio-artificial tissue engineering structures. We present the results of studying the structure of porous bioresorbable polymer matrices for tissue engineering using X-ray microtomography. Samples were obtained by supercritical fluid plasticization of D,L-polylactide with subsequent foaming in cylindrical molds. The tomographic method makes it possible to construct a three-dimensional voxel model of the object under study and gain apart from the estimate on the integral matrix porosity (characteristic data obtained by traditional sorption procedures) additional information about the size and spatial distribution of pores thus providing a possibility of optimization of the process parameters for production of polylactide matrices required for specific biomedical applications of architectonics, as well as forecasting the processes of their bioresorption in enzymatic media. The experiments were carried out on a laboratory microtomograph (Mo anode, the scan time of the sample is 120 min, the detector pixel size is 9 μm). Tomographic reconstruction was performed by algebraic method. The binarization procedure required for calculation of the structural characteristics of studied matrices was implemented by the method with the choice of a global threshold. Calculations of the porosity and homogeneity of the porosity distribution in the bulk, as well as estimation of the specific surface area of pores revealed the isotropy of the spatial structure of polylactide matrices.
Data fitting problem under interval uncertainty in data
Authors: Shary Sergey P.
Published: February 2020

We consider the data fitting problem under uncertainty, which is not described by probabilistic laws, but is limited in magnitude and has an interval character, i.e., is expressed by the intervals of possible data values. The most general case is considered when the intervals represent the measurement results both in independent (predictor) variables and in the dependent (criterial) variables. The concepts of weak and strong compatibility of data and parameters of functional dependence are introduced. It is shown that the resulting formulations of problems are reduced to the study and estimation of various solution sets for an interval system of equations constructed from the processed data. We discuss in detail the strong compatibility of the parameters and data, as more practical, more adequate to the reality and possessing better theoretical properties. The estimates of the function parameters, obtained in view of the strong compatibility, have a polynomial computational complexity, are robust, almost always have finite variability, and are also only partially affected by the so-called Demidenko paradox. We also propose a computational technology for solving the problem of constructing a linear functional dependence under interval data uncertainty and take into account the requirement of strong compatibility. It is based on the application of the so-called recognizing functional of the problem solution set — a special mapping, which recognizes, by the sign of the values, whether a point belongs to the solution set and simultaneously provides a quantitative measure of this membership. The properties of the recognizing functional are discussed. The maximum point of this functional is taken as an estimate of the parameters of the functional dependency under construction, which ensures the best compatibility between the parameters and data (or their least discrepancy). Accordingly, the practical implementation of this approach, named «maximum compatibility method», is reduced to the computation of the unconditional maximum of the recognizing functional — a concave non-smooth function. A specific example of solving the data fitting problem for a linear function from measurement data with interval uncertainty is presented.
USE OF AGRICULTURAL WASTE ASHES AS ADDITIVES MATERIAL IN BIOACTIVE GLASS PRODUCTION
Authors: ÖZOCAK Murat
Published: February 2020

Demand for renewable energy sources is increasing day by day. The rapidly increasing population and energy needs on a global scale have increased the number of studies on renewable energy sources. In addition to energy needs, the search for disposal and storage of wastes harmful to the natural environment is of great importance. Disposal and storage requires high costs and labor. The need for energy and the necessity of protecting the natural environment provided the solution to convert wastes into energy or value added products without damaging the environment. The wastes of the crops produced as a result of agricultural production can be converted into energy or value added products. Some of the plant wastes meet the energy needs and some of them can be used in the production of value-added biomaterials. Biomaterials are materials which are used in the field of health and show bioactivity with parts such as organs and tissues. Bioactive glasses, which are one of these materials, are used in the health sector especially in dental filling, prosthesis and composite applications. The most important feature of raw materials to be used in the production of bioactive glasses is SiO2 (silica). Plants receive silica from soil during development and this silica is also present in plant waste. In this study, a wide literature review was conducted and the percentage of mass ash after burning of rice stalks, corn stalks, hazelnut shells, corn stalks which were firstly burned for heating and energy purposes were determined. Then, the composition of the ash obtained SiO2 (silica) and other substances were determined and all the results obtained in the light of this information was compiled to provide information about the possibilities of use in bioactive glass production.

Published: February 2020

El presente artículo está basado en una investigación de enfoque etnográfico realizada entre 2016 y 2018, y ofrece un acercamiento a la percepción de lo que se podrían denominar identidades homosexuales en contextos indígenas, específicamente en una escuela secundaria ubicada en un ejido del municipio de Ocosingo, Chiapas. Se analizan situaciones conflictivas que experimentaron tres alumnos que se habían asumido como antsiwiniketik partir de la relación con sus compañeros y adultos dentro y fuera de la escuela. Para su análisis se recuperan aportaciones teóricas y conceptos tales como: lucha de poder, heteronorma, sistema sexo-género, estudios de género, teoría queer e interculturalidad.
El liderazgo "mandar obedeciendo" se fundamenta en el sacrificio del hermano mayor
Authors: García Bravo Ana Bertha , Parra Vázquez Manuel Roberto
Published: February 2020

En México, donde el 15% de la población es indígena, hay poca literatura que trate sobre las características del liderazgo indígena local. El objetivo de este estudio fue describir las características del liderazgo indígena tsotsil. Se encontró un sistema de organización en el que el líder obedece lo encomendado por el grupo al que representa. El principal rasgo motivacional que busca la comunidad en el líder es el "sacrificio", lo cual se entiende por el concepto bankilal (hermano mayor), persona que debe cuidar de los hermanos menores. Se puede confirmar lo que afirman los zapatistas: en las comunidades indígenas los líderes mandan obedeciendo a la comunidad que representan.
Fluid Inclusions and Rare Earth Elements (REE) analysis in calcite veins: Tectonic - diagenesis interaction in the Rosablanca formation, Mesa de los Santos sector, eastern cordillera, Colombia
Authors: Conde-Gómez Jairo
Published: February 2020

Studies conducted by means of petrography, cathodoluminescence, SEM, fluid inclusion and REE geochemistry in core samples from the Rosablanca Formation in the Mesa de Los  Santos sector, identified two types of material: the host rock classified as Packstones and Grainstones, and veins that texturally expose three types of filling (blocky texture, blocky elongate texture, fibrous texture). Diagenesis is characterized by dissolution, carbonate cement precipitation, compaction, fracturing and fluid circulation through fractures during at least three episodes; these diagenetic processes were contemporaneous with the distensive and compressive tectonic regimes regionally dominant during the Cretaceous, Paleogene and Neogene in the study area. The fluids that generated the different types of texture inside the veins were brines that belonged to the H2O – NaCl – CaCl2 system, with salinities between 0.03 – 12.96 % wt eq NaCl, derived from the Rosablanca Formation that was deposited under oxic conditions, retaining their marine character and implying an autochthonousorigin for the REE present in the veins. The conditions of entrapment for fluid inclusions during the early event were heterogeneous, arising from an immiscible mixture of brines andhydrocarbons, while in the second, they were homogeneous with later post-entrapment processes.later post-entrapment processes.

Biourine which is widely known as liquid organic fertilizer is one of the alternative efforts in waste treatment, especially animal urine to become something that is more beneficial for the environment. One of the biourine benefit is to maintain soil fertility which is can increase farmer productivity. The aim of the research was to test the quality of local microorganisms (MOL) and goat biourine which had been made in different formulas, and to determine the best biourine in kale. MOL was made by four main raw materials, they are cow’s rumen, golden snail, bamboo shoots, and banana weevil. The making of MOL needed 14 days of processing in aerobic system. Then, 10% of MOL that had been made was added to goat urine to make biourine in the same aerobic system. The best biourine will be tested by watering kale. From the observations, it was obtained that the composition of raw materials from existing formulas affects the quality of the MOL produced. The quality affects the final result of the biourine. The best selected biourine has N and P content of 2.23% and 0.11% respectively. The amount of biourine applied to water kale was 0.4 ml / planting hole. The result showed kale which was watered by biourine treatment produced higher production levels than negative control plants but the difference was not significant. But these results was still lower than positive control by the treatment of chemical fertilizers.

The aim of this study was to identify the polymorphism of the CD1B gene in c.248 in exon 3 and its association with IgY and ND titers in sentul chicken Sensi-1 Agrinak line. IgY is the main antibody of chickens while the ND titer is an ND specific antibody, both of which have an important role in the response of disease resistance. The Cluster of differentiation 1B (CD1B) gene is one of the major genes of disease resistance that functions in representing antigens through specific immune responses. This study used 17 sensi-1 chicken lines. The study was conducted by PCR sequencing method, ELISA test, and HI test. The result showed mutation on c248 A>G in exon 3. The SNP were polymorphic and Hardy Weinberg equilibrium. Thre were two A and G alleles and 3 genotypes namely AG, GG, and AA. The frequency of the GG genotype was higher (0.41) compared to other genotypes. The AG genotype were associated with IgY production and were not associated with ND titers.
