Budding YeastBFA1Has Multiple Positive Roles in Directing Late Mitotic Events
Authors: Whalen Jenna , Sniffen Courtney , Gartland Siobhan , Vannini Michael , Seshan Anupama
Published: January 2019

The proper regulation of cell cycle transitions is paramount to the maintenance of cellular genome integrity. In Saccharomyces cerevisiae, the mitotic exit network (MEN) is a Ras-like signaling cascade that effects the transition from M phase to G1 during the cell division cycle in budding yeast. MEN activation is tightly regulated. It occurs during anaphase and is coupled to mitotic spindle position by the spindle position checkpoint (SPoC). Bfa1 is a key component of the SPoC and functions as part of a two-component GAP complex along with Bub2. The GAP activity of Bfa1-Bub2 keeps the MEN GTPase Tem1 inactive in cells with mispositioned spindles, thereby preventing inappropriate mitotic exit and preserving genome integrity. Interestingly, a GAP-independent role for Bfa1 in mitotic exit regulation has been previously identified. However the nature of this Bub2-independent role and its biological significance are not understood. Here we show that Bfa1 also activates the MEN by promoting the localization of Tem1 primarily to the daughter spindle pole body (dSPB). We demonstrate that the overexpression of BFA1 is lethal due to defects in Tem1 localization, which is required for its activity. In addition, our studies demonstrate a Tem1-independent role for Bfa1 in promoting proper cytokinesis. Cells lacking TEM1, in which the essential mitotic exit function is bypassed, exhibit cytokinesis defects. These defects are suppressed by the overexpression of BFA1. We conclude that Bfa1 functions to both inhibit and activate late mitotic events.

Published: January 2019

Implicit assumption of common (co)variance for all loci in multi-trait Genomic Best Linear Unbiased Prediction (GBLUP) results in a genomic relationship matrix (G) that is common to all traits. When this assumption is violated, Bayesian whole genome regression methods may be superior to GBLUP by accounting for unequal (co)variance for all loci or genome regions. This study aimed to develop a strategy to improve the accuracy of GBLUP for multi-trait genomic prediction, using (co)variance estimates of SNP effects from Bayesian whole genome regression methods. Five generations (G1-G5, test populations) of genotype data were available by simulations based on data of 2,200 Danish Holstein cows (G0, reference population). Two correlated traits with heritabilities of 0.1 or 0.4, and a genetic correlation of 0.45 were generated. First, SNP effects and breeding values were estimated using BayesAS method, assuming (co)variance was the same for SNPs within a genome region, and different between regions. Region size was set as one SNP, 100 SNPs, a whole chromosome or whole genome. Second, posterior (co)variances of SNP effects were used to weight SNPs in construction of G matrices. In general, region size of 100 SNPs led to highest prediction accuracies using BayesAS, and wGBLUP outperformed GBLUP at this region size. Our results suggest that when genetic architectures of traits favor Bayesian methods, the accuracy of multi-trait GBLUP can be as high as the Bayesian method if SNPs are weighted by the Bayesian posterior (co)variances.

Authors: Mardiah Irma
Published: January 2019

Endophytic bacteria is an excellent candidates for the biological control of pathogenic fungi in plantations. The objectives of this study were to isolate and examine anti-fungal activity of endophytic bacteria from oil palm plantations in South Kalimantan against Ganoderma boninense. This research was performed in three phases, i.e., isolation, selection, and assessment of endophytic bacteria isolates against Ganoderma boninense. A total of 126 colonies of endophytic bacteria were isolated. The result of the anti-fungal activity test with dual culture method demostrated that BKA 10 isolate had the largest inhibition zone (62.22%). Molecular identification by DNA analysis using 16S rRNA primers showed that BKA 10 is most closely related to Bacillus cereus. In conclusion, isolate with the best anti-fungal acitivity against Ganoderma boninense has the closest kinship with Bacillus cereus. Keywords: antifungal, dual culture, Bacillus cereus.

OBJECTIVES:

To identify modifiable factors that facilitate discussion of potentially sensitive topics between health care providers and young people at preventive service visits after Patient Protection and Affordable Care Act implementation.

METHODS:

We used data from a national internet survey of adolescents and young adults (13–26 years old) in the United States. Questionnaire construction was guided by formative research and Fisher’s Information-Motivation-Behavioral Skills model. Those who had seen a regular health care provider in the past 2 years were asked about 11 specific topics recommended by national medical guidelines. Four multivariable regression models were used to identify independent predictors of discussions of (1) tobacco use, (2) drug and/or alcohol use, (3) sexually transmitted infections or HIV, and (4) the number of topics discussed.

RESULTS:

Fewer than half of young people reported having discussed 10 of 11 topics at their last visit. Predictors were similar across all 4 models. Factors independently associated with health discussions included the following: ever talked with a provider about confidentiality (4/4 models; adjusted odds ratio [aOR] = 1.85–2.00), ever had private time with a provider (1 model; aOR = 1.50), use of health checklist and/or screening questionnaire at last visit (4 models; aOR = 1.78–1.96), and time spent with provider during last visit (4 models). Number of years that young men had seen their regular provider was significant in 1 model. Other independent factors were positive youth attitudes about discussing specific topics (3/3 models) and youth involvement in specific health risk behaviors (3/3 models).

CONCLUSIONS:

Discussions about potentially sensitive topics between health care providers and young people are associated with modifiable factors of health care delivery, particularly provider explanations of confidentiality, use of screening and/or trigger questionnaires, and amount of time spent with their provider.
The results of the research of sandstones closed porosity
Authors: Baranov V. A. , Antipovich Y. V.
Published: January 2019

The article presents the results of the study of gas inclusions in quartz grains of Donets Basin sandstones. It describes the main genetic types of inclusions, their conditions of formation, shape, size, as well as features of the transformation under the conditions of catagenesis of rocks.The presence and distinctive features of the primary and secondary inclusions were established by studying of their homogenization temperatures. Thanks to these studies, it was found that the homogenization temperature of the primary inclusions is 1.5–2 higher than for secondary ones. Also, characteristic of the primary inclusions is that they are mainly gas-liquid. In size, primary inclusions are 1.5–2 times larger than secondary ones, and on average they are 2–3 µm. Secondary inclusionsessentially consist of gas. A characteristic feature of secondary inclusions in quartz grains of the sandstones of the Donetsk Basin is that they decorate the microdeformations of these grains, thereby forming numerous Boehm stripes. The gas inclusions of Boehm strips are indicators of paleotemperature, and the Boehm strips themselves carry information about paleopressure. To calculate the volume of gas inclusions, a methodwas proposed.This method is easy to use and does not require significant financial expenses. For its implementation, standard petrographic thin sections are used, which are examined using an optical microscope with a total magnification of 1000-1200 times. Using the proposed method, the volumes of gas inclusions in quartz grains of sandstones of different substages of catagenesis were established. Considering that gas inclusions are part of closed porosity, it is proposed to conditionally subdivide closed porosityinto cement closed porosity (volume of closed pores in the cementing substance of the rock) and grain closed porosity (volume of closed pores in detrital grains of the rock). It is established that the indicator of grain closed porosity is 2-3 times higher than the indicator of cement closed porosity. The largest volumes of gas inclusions are established for the middle substage of catagenesis. Considering that rock and gas outbursts occur only at the middle substage of catagenesis, this confirms the theory about the additional effect of gas inclusions on the progress of gas-dynamic phenomena in mine opening.Also, duringthe determination of absolute porosity of rocks in laboratory conditions, it is very important to grind the rock to micron-sized fraction. This will allow opening a part of inclusions in the clastic grains of rocks, which will substantially complement the indexes of absolute porosity.

The results of analysisof the patterns of the spatial relationship between hydrothermal gold ore formations and the zones of metasomatites and systems of deep faults within the Chortomlyk greenstone structure of the Middle Pridniprovie megablock in the Ukrainian Shield are given. As a result of studying the localization conditions of gold mineralization, it was established that the gold-bearing mineralization is confined to tectonically fractured zones and is localized among metasomatically altered rocks. The hydrothermal series of metasomatites in the Chortomlyk greenstone structure is represented by greisens, propylites, amphibole-carbonate metasomatites and listvenite-berezites. The mineralization of Au and Mo is associated with metasomatites of the greisen type. The study of spatial relationship between the fields of metasomatites and the gold mineralization and zones of deep faults revealed that the closest relationship is expressed with systems of faults with azimuths of 0° and 270°, 17° and 287°, 77° and 347°. The results of the studies allowed us to develop a newprospecting criterion, which, in turn allows us to state that the gold mineralization within the Chortomlyk greenstone structure is spatially confined to metasomatites related to the schistosity, fracture, millonitization, and cataclase zones with high content of sulphide mineralization. These zones are localized in nodes of intersecting faults of the first order of the system 77° and 347° with discontinuous violations of high orders of azimuths of 0° and 270°, 17°and 287°. The results of the research can be used to develop a set of predictive criteria and the allocation of promising sites of hydrothermal mineralization of gold within the Chortomlyk greenstone structure of the Middle Pridniprovie megablock in the Ukrainian shield.

An Examination of the Validity and Factor Structure Regarding Cognitive and Affective Responses for the Development of a Travel Involvement Scale: Based on the Kapferer-Laurent’s CIP and Zaichkowsky’s PII Scales
Authors:   The Tourism Sciences Society Of Korea, Choi In Mook
Published: January 2019

This study intended to develop travel involvement scales as a preliminary method for researchers to gradually change and specialize these scales. In order to develop a scale, Kapferer-Laurent’s CIP and Zaichkowsky’s PII scales were reviewed in detail as the validity of those scales had been tested for quite a long time. Reconstruction of the reviewed scales helped to develop a preliminary one. The researchers perceived that the product involvement under product dominant logic could not include intangibility and heterogeneity of travel services rather than under service dominant logic. This study suggests that the factor structure regarding affective factors including “enjoyable,” “trustworthy,” “friendly,” and “addictable” and the cognitive factors including “comparable,” “expressible,” and “considering safety” are valid. Furthermore, the level of travel involvement verified discriminant validity through HCHA, HCLA, LCLA, and LCHA. This would indicate that this study supports an interaction between affective and cognitive, rather than separated paths, in the information process for travel involvement.

The solution of the problem of controlling the arc welding process by robotic technological complexes by the quality criterion of the produced products is proposed in this paper. The statement of the problem is given, the criterion of the quality in the form of the goal function is described. The mathematical models based on the principles of J. Forrester’s system dynamics is developed. The main indicators that affect the quality of the welding process in RTC and their relationships are identified as system levels. The external factors that depend on the indicators and affect them are also defined. The functional dependencies of the indicators were obtained as a result of approximation of statistical data based on long-term observations of the process. A system of the differential equations that describe the cause-effect relationships between the indicators and the factors is developed. Based on the mathematical model, an algorithm for the search for control actions, the implementation of which minimizes the goal function was developed. The developed models and the control algorithms might significantly improve the quality of the arc welding process. The proposed software is testing as a part of the RTC Kawasaki technical control system at OJSC "Transmash" (Engels, Russia).

Authors: Averianova Nina
Published: January 2019

It is shown, that for the further development of the Ukrainian Statehood the feeling of the national unity of all elitist groups and agreement by them about strategical perspectives of the nation’s progress is necessary. The powerful factors of consolidation of Ukrainianess are forming presence of national elite that must instance public unity. Influence of national elite on development of all spheres of life of the state, on introduction and efficiency of functioning of democratic reforms in a country, on the level of economic and spiritual stability in society does not cause doubts. Consolidation of Ukrainianess depends on ability national of economic, intellectual and other political elites to produce strategies of development of the state protect her interests directly. The process of consolidation is protracted and heavy, he presents a main socio-political task to development of society. And as exactly a national elite forms reference points for advancement of the state, then it is necessary, that she, first of all, was of interest all society, was highly skilled and enjoyed a confidence among a population, successive and open in the actions, shut out internal conflicts and squabbles, that will become the mortgage of rallying of all Ukrainianess. As elites play in the society certain social functions, so the different elite’s groups are marked out. Each of these groups realizes its own complex of duties, so that the criteria, determining the belonging to some of the elitist group are different. In this study the condition of the modern Ukrainian artistic elite is analyzed. The result of artistic and practical activity of the artistic elite is art which appears as a specific means of influencing public consciousness. The art represents significant and value dimension of the national being of the Ukrainianess, gives a vision of historical being of the Ukrainian national, reflects spiritual links between a personality and the national, spiritual unity and succession of generation. That is why purposeful usage of art in modern conditions the can be a powerful factor of consolidation of Ukrainianess. The artistic elite of Ukraine creating artistic works offering cultural and artistic programs and projects should lay the ideas of national unity and patriotism in them.

This article seeks to answer the following research question: would it be possible to claim that in the events of the births of babies suffering from a congenital disease that involves a physical or a mental disability which went promptly unnoticed due to a prenatal diagnosis error, the parents should be awarded any kind compensation for damages provided under the Colombian legal system? In order to answer the question, the legal claim referred as wrongful birth is reviewed under the comparative law and its autonomy against other wrongful actions related to the exercise of the reproductive freedom and the responsible parenthood liberties (wrongful life, wrongful conception and wrongful adoption), based upon which, the analysis of each one of the elements of civil liability in our country is undertaken in the events of wrongful birth, to conclude its viability in Colombia and introduce a possible damage compensation scheme for this subject.
Legalidad de la prueba y la exclusión
Authors: Echeverry Enciso Yecid
Published: January 2019

The principles, within the Colombian legal system, are considered as norms of immediate application, for the role they play in the protection of fundamental and constitutional guarantees to citizens. In this sense, they are precepts against which one cannot be indifferent, especially when dealing with the actions of a judicial or administrative authority, since their activities are regulated by legal requirements, which must always support such actions. This is how we arrive at the principle of legality or duty of justification of administrative action in previous normative precepts. In this sense, the principle of legality guarantees in the process that all stages are met in accordance with what is legally established, a situation that involves, as is logical, the evidentiary stage both in obtaining the evidence and in its incorporation into the process; these stages are expressly regulated, and the lack of those guidelines or the violation of rights and fundamental guarantees during their execution are sufficient reason to invalidate and exclude the evidence of the process as sanction for its illegality.

Published: January 2019

A ocorrência de mamíferos do Pleistoceno é registrada desde o século XIX em quase todos os estados do Brasil. Na Bahia, entre 1817 e 1820, Johann Baptiste von Spix e Carl von Martius relataram fósseis no povoado de Barriga Mole (Andorinha), microrregião de Senhor do Bonfim, mas somente a partir da década de 1980 esta área começou a figurar na bibliografia nacional, especialmente após os trabalhos de campo de Castor Cartelle (PUC-MG) e colaboradores. A coleção do Laboratório de Arqueologia e Paleontologia da UNEB (Campus VII) apresenta fósseis de mamíferos do Pleistoceno da microrregião de Senhor do Bonfim, coletados em cavernas e em outros jazigos fossilíferos de quatro municípios: Senhor do Bonfim, Campo Formoso, Filadélfia e Andorinha. No presente trabalho foram estudados e identificados seis taxa de mamíferos, incluindo Eremotherium laurillardi, Glyptotherium sp., Panochthus sp., Notiomastodon platensis, Palaeolama major e Toxodontinae indeterminado, colaborando com o conhecimento acerca da composição paleofaunística da região durante o Pleistoceno final.

Published: January 2019

A área de estudo está localizada na plataforma continental do município de Luís Correia, no estado do Piauí, região ainda pouco estudada, no contexto da bacia do Ceará, especificamente a sub-bacia do Piauí-Camocim. Dada à falta de estudos nesta área, foi considerado importante realizar uma caracterização morfológica da plataforma continental de Luís Correia. Para desenvolver este trabalho foram utilizadas imagens do satélite Landsat 8 para identificação das formas de fundo. Adquiridas no site do INPE, as imagens foram gravadas, filtradas e interpretadas nos softwares ArcGIS 10 e Envi 4.8, com a correção geométrica com base nas imagens do Geocover. Foram também utilizados dados batimétricos extraídos da base de dados ETOPO-1 no site NOAA, os quais foram validados de acordo com as cartas náuticas da Diretoria de Hidrografia e Navegação (DHN). Com os dados batimétricos foram traçados dois perfis, um na costa leste, outro na costa oeste da área e a elaboração de um mapa de declividade. Com isso, foi possível identificar algumas estruturas como os paleocanais associados à foz do rio Parnaíba e rio Portinho. Através dos perfis foi possível compartimentar a plataforma em interna, média e externa com a zona de quebra da plataforma continental ocorrendo a cerca de 80 km do continente. Exibe inclinação menor que 1º, pequenas variações ocorrendo, sendo a maior variação na plataforma externa e na zona de quebra da plataforma, onde a declividade muda abruptamente para uma inclinação de 8,5º, variação esta que ocorre a 80 km da linha de costa. Recomenda-se um estudo batimétrico mais detalhado para a melhor caracterização das feições submersas identificadas na área.

Published: January 2019

Background: Vitamin D deficiency in exclusively breast fed infants was increasing in young infants. Many studies were done previously but still the data on vitamin D status of healthy term infants are scanty. Hence the present study was done to determine the prevalence of subclinical vitamin D deficiency among exclusively breast fed babies by estimating the serum levels of relevant parameters.Methods: The present descriptive study included 40 babies that are exclusively breast fed healthy term babies with birth weight >2.5kg. After collection of complete demographic and antenatal data, serum was collected from all the babies to estimate serum levels of vitamin D (25OH-D3) and calcium, phosphate, and alkaline phosphatase.Results: Out of 40 babies, vitamin D deficiency was found in 33 (83%) babies. Of them, hypocalcaemia was seen in 13 (39.3%) infants. Raised ALP was noticed in all babies with a mean value of 464.97 IU/L. Phosphorus levels were normal in all babies with a mean value of 6.12 mg/ml.  Serum 25 OH vitamin D3 levels were low (mean-10.02 ng/ml) and mean calcium was 8.81 mg/dl.Conclusions: Prevalence of vitamin D deficiency was found to be high in exclusively breastfed babies with hypocalcemia in 39% of babies and associated seizure in one baby in this study.

White Mensural Manual Encoding: from Humdrum to MEI
Authors: Rizo Valero David , Pascual León Nieves , Sapp Craig Stuart
Published: January 2019

The recovery of musical heritage currently necessarily involves its digitalization, not only by scanning images, but also by the encoding in computer-readable formats of the musical content described in the original manuscripts. In general, this encoding can be done using automated tools based with what is named Optical Music Recognition (OMR), or manually writing directly the corresponding computer code. The OMR technology is not mature enough yet to extract the musical content of sheet music images with enough quality, and even less from handwritten sources, so in many cases it is more efficient to encode the works manually. However, being currently MEI (Music Encoding Initiative) the most appropriate format to store the encoding, it is a totally tedious code to be manually written. Therefore, we propose a new format named **mens allowing a quick manual encoding, from which both the MEI format itself and other common representations such as Lilypond or the transcription in MusicXML can be generated. By using this approach, the antiphony Salve Regina for eight-voice choir written by Jerónimo de la Torre (1607–1673) has been successfully encoded and transcribed.

Introduction: bacterial keratitis caused by Pseudomonas aeruginosa is one of the causes of blindness in the world, due to pathogenicity of the bacteria that can lead to corneal perforation. Studies on the protein annexin A1 (AnxA1) point it as one of the essential mediators in homeostasis of inflammation and ocular infections. However, there are no known reports of AnxA1 in keratitis. Objetive: to investigate the expression profile of AnxA1 in the P. aeruginosainduced keratitis model in two strains of mice (susceptible and pathogen resistant).Method: for the development of experimetal keratitis, the mice had their right eyes ulcerated and immediately inoculated with 5 μl of P. aeruginosa in PBS. The animals were euthanized after 24 hours of the bacteria inoculation. The eyes were clinically evaluated and histopathologically processed for quantitative analyses of the inflammatory infiltrate and immunohistochemical studies of the expressions of the AnxA1 and the receptor for formylated peptides (fpr2).Results: our results demonstrated a higher influx of inflammatory cells, mainly neutrophils in the susceptible animals (C57BL / 6) compared to those considered resistant (BALB / c) and controls. Immunohistochemical studies indicated weak expression of AnxA1 and fpr2 in the anterior epithelium and stroma of the cornea. However, after keratitis induction, overexpression of AnxA1 and fpr2 occurred in the corneas of both mice strains. Furthermore, greater expression of AnxA1 in the anterior corneal epithelium was observed in the C57BL / 6 animals.Conclusions: AnxA1 and fpr2 may be related to infectious keratitis induced by P.aeruginosa, which stimulates further investigations on the use of AnxA1 as a possible coadjuvant therapeutic strategy in bacterial keratitis.
Complete Scheme for Fullerene, Graphene, and Soot Formation in Flame
Authors: Mansurov Z.A.
Published: January 2019

Soot formation processes have been studied for more than 100 years, they include empirical and phenomenological description of conversion of various fuels to soot particles. This article provides an overview of current state of soot formation foundations, including the chemistry of soot nucleation, nucleation, mass growth as well as size of soot particles. Consideration of this issue shows that a great progress has been made, but there is still a lot of ambiguity in many areas of our knowledge. This concerns the role of aromatic molecules and radicals in nucleation and subsequent growth mass in laminar pre-mixed flames. Along with environmental problems, in recent time there are considered soot particles as an environment for nanomaterial synthesis, such as fullerenes, carbon nanotubes and graphenes. In this regard, a complete scheme of nanomaterials formation in mode of soot formation has been developed.

Published: January 2019

The possibility of using sewage sludge (WWS) as an organic fertilizer has been studied. The Sludge is formed after the wastewater treatment of the meat industry production with actinomycetes Str. chromogenes s.g. 0832. This microorganism is adapted to specific protein contamination of wastewater. The sludge is characterized by a high content of organic matter (57.3-62.5%). Free amino acids make up 70% of the total protein. The share of essential amino acids in WWS accounts for 41.44%. Of the heavy metals, only Zn and Cu were detected in it. At the same time, Zn content is 7.9 times lower than permissible, Cu - 3.8 times. WWS is not toxic in doses applied to the soil. Marked a significant increase in the biomass of spring rapeseed on all experimental samples. The highest yield increase of 187.6% is observed at the dose of WWS 10t/ha. Evaluation of rapeseed seed products showed a high increase of seeds on soils with addition.

Authors: Fomenko A.I. , Sokolov L.I.
Published: January 2019

The sorption characteristics of aluminosilicate microspheres of fly ash from thermal power plants with respect to heavy metal ions were studied with a view to their subsequent use for integrated treatment of household and industrial wastewater. The mechanism and kinetics of the sorption of total iron ions from aqueous solutions are studied, quantitative characteristics of the sorption capacity and adsorption equilibrium constants are obtained. It has been established that aluminosilicate microspheres of fly ash possess sorption properties with respect to common iron ions. The sorption isotherm of iron ions from water by the material under study is characteristic of microporous sorbents. The quantitative characteristics of the sorption process allow us to conclude about the possibility of using aluminosilicate fly ash microspheres without any additional treatment for the purification of waste water from heavy metal ions.

Published: January 2019

Background: Scorpions are one of the most important venomous animals in Iran. Their sting has more prevalence in the south and southwest areas. The aim of this study was to introduce their sting agent species in the country.
Methods: Data were extracted by a mini review on scorpion stinging articles in Iran until early 2018 and then the sting agent species in each area were studied. Geographical and provincial distribution of each species also was provided.
Results:  Twelve scorpion species are causative agents of sting. According to their deadly rate and clinical symptoms, some of them are considered the most dangerous venomous animals in Iran. Some death cases have been reported be­cause of the sting of 3 species of Hemiscorpius lepturus, H. acanthocercus and Androctonus crassicauda. Remaining species have not deadly sting but because of their frequency, they encounter the individuals and cause the stinging.
Conclusion: The highest number of sting agents is in Khuzestan, however Gilan and Mazandaran have the lowest fre­quency. Because of the high prevalence of sting agent species in that province, the necessity of providing control and prevention programs is very important.

Published: January 2019

Background: The common bed bug (Cimex lectularius), a nocturnal blood-feeding ectoparasite, is considered an urban pest with public health importance in human environments. We aimed to determine the repellency effect of oregano essential oil, Origanum vulgare, against this pest under laboratory conditions.
Methods: The essential oil was prepared from dried leaves using hydro-distillation method. A gas chromatography-mass spectrometer (GC-MS) was used for analysis and identification of oregano essential oil compounds. Treated surface method in Petri dish was carried out to evaluate repellency potential of the oil using 4th and 5th instar nymphs and adults. The concentration-repellency response of oregano essential oil was calculated and compared with a commercial insect repellent stick containing 33% N, N-diethyl-meta-toluamide (DEET).
Results: The oregano essential oil consisted of 158 compounds with terpineol (22.85%) and α–terpinene (20.60%) being the major components by volume. The EC50 and EC99 of oregano oil (effective concentrations causing 50% and 90% repellency of bed bugs) were 1.61 and 6.57mg/cm2 at 9h after application, respectively. The 40% oregano es­sential oil exhibited 100% repellency against bed bug at 3, 5, 9 and 24h after application while the repellency index of DEET 33% was 100% at 3 and 5h and it decreased to 80% and 27% at 9 and 24 hours.
Conclusion: Oregano oil 40% exhibited more repellency compared to commercial insect repellent stick containing 33% DEET. Further studies are warranted to confirm the effectiveness of oregano essential oil in personal protecting against bed bug biting.

Published: January 2019

Modal pseudocomplemented De Morgan algebras (or mpM-algebras) were investigated in A. V. Figallo, N. Oliva, A. Ziliani, Modal pseudocomplemented De Morgan algebras, Acta Univ. Palacki. Olomuc., Fac. rer. nat., Mathematica 53, 1 (2014), pp. 65–79, and they constitute a proper subvariety of the variety of pseudocomplemented De Morgan algebras satisfying xΛ(∼x)* = (∼(xΛ(∼x)*))* studied by H. Sankappanavar in 1987. In this paper the study of these algebras is continued. More precisely, new characterizations of mpM-congruences are shown. In particular, one of them is determined by taking into account an implication operation which is defined on these algebras as weak implication. In addition, the finite mpM-algebras were considered and a factorization theorem of them is given. Finally, the structure of the free finitely generated mpM-algebras is obtained and a formula to compute its cardinal number in terms of the number of the free generators is established. For characterization of the finitely-generated free De Morgan algebras, free Boole-De Morgan algebras and free De Morgan quasilattices see: [16, 17, 18].
Logiki dyskursów

Główną tezą przedstawioną w artykule jest twierdzenie, że różne rodzaje komunikacji mają różne bazy odniesienia sensu i różne mechanizmy interpretacyjne, które pozwalają na osiągnięcie stanu rozumienia w odpowiednim rodzaju komunikacji. Można przyjąć, że istnieje jedna początkowa uniwersalna logika, pozwalająca na racjonalizację całego procesu analizy rzeczywistości przez człowieka, jej kategoryzację i ustalenie związków przyczynowo-skutkowych, lecz nie pozwala ona na skuteczną interpretację i rozumienie przekazów we wszystkich złożonych sytuacjach komunikacyjnych i w każdym wyspecjalizowanym dyskursie. Jak pokazuje praktyka, uczestnictwa w różnych rodzajach komunikacji (dyskursach) trzeba się uczyć i wstępne predyspozycje logiczne każdego człowieka nie wydają się wystarczające, by od razu skutecznie w nich komunikować.

Groundwater plays a pivotal role as the largest potable water sources in Bangladesh. However, the quality of the groundwater faces challenges due to xenobiotic compounds in it. Excess amount of arsenic (As) has already been found in groundwater in many parts of Bangladesh. Thus, this study was conducted to assess the water quality and associated human health risk in central Bangladesh. A total of 99 groundwater samples from the central part of Bangladesh were analyzed to assess human health risk due to high level of nitrate (NO3-) and other trace elements i.e. arsenic (As), iron (Fe), and manganese (Mn). It was found that NO3- concentration (253.17 mg/L) in the groundwater samples exceeds the recommended guideline value by the WHO (50 mg/L). Moreover, this study area also characterized with elevated concentration of As (19.44 µg/L), Fe (811.35 µg/L), and Mn (455.18 µg/L) in the groundwater. Non-carcinogenic human health risk was calculated by justifying HQ (Hazard Quotient) and HI (Hazard Index) and attributed potential conjunctive human health risks due to NO3-, As, Fe and Mn in the study area. Moreover, high carcinogenic risk was found due to As contamination in the groundwater samples in the study area.

Published: January 2019

SME funding needs have not been fully met. IPO is one of the efforts that can be done by SMEs to meet these funding needs. However, it is not yet known whether the financial performance of SMEs will increase after conducting an IPO. This study aims to analyze the financial performance of SMEs before and after the IPO. The sample of this study is SMEs that listed on the IDX in 2017, which is as many as five SMEs. SME financial performance is measured through three SME financial ratios, namely liquidity, solvency, and profitability. The paired sample t-test was used to compare the financial performance of SMEs before and after the IPO. The results showed that there is no significant difference in the financial performance of SMEs before and after the IPO. The results of this study provide recommendations for further research related to the valuation and performance of SME IPOs.
