Authors: Satria Hanafi Aprizal , Sholihah Qomariyatus
Published: September 2019

Unlocked energy in the machine can cause heavy equipment to move suddenly, it can hit the mechanics that are working. LOTO devices are required in this case. LOTO is a locking and labeling system for energy sources so that occupational accidents can be prevented. This study aim to know the difference of occupational accident cases on heavy equipment mechanics before and after using LOTO devices. A quasy experiment approach was used to evaluate occupational accidents. This design uses two group, intervention group, and control group, 32 heavy equipment mechanics were given LOTO device and 32 heavy equipment mechanics were not given LOTO device.Based on pre-evaluation, evaluation 1, and evaluation 2Â  there is a decrease in the number of occupational accidents in the intervention group after given LOTO device. Statistical test showed there was a difference in occupational accidents before and after the use of LOTO device on heavy equipment mechanics based on type of accidents (beaten, p = 0.001), (falling, p = 0.005), (pinched, p = 0.001), (pressed, p = 0.001), (crushed, p = 0.000).LOTO devices proved to be effective in preventing and reducing the number of occupational accidents in the heavy equipment mechanics.

Authors: Karamoy Youla
Published: September 2019

Dental and mouth health play an important role to get good health. Mouth disease cause pain, suffering, social deprivation and psychologi-cal barriers, which are highly detrimental to both individuals and society including the children. School age children is one of the groups that are vulnerable to dental and mouth health problems. The study aim to know the relationship of dental and mouth disease with the childâ€™s quality of life. The study design was cross-sectional conducted in North Minahasa subdistrict with sample taken by convenience sampling. Data analysis of univariate and bivariat analysis. Results of univariate analysis obtained average dental caries with PUFA index was 0.77 and the Calculus Index (CI) was 0.75. The average of PUFA index of subjects whose parents work in nonformal higher (0.88) than subjects whose parents work in a formal (0.76). Bivariat analysis obtained significant corelation between dental caries and the childâ€™s quality of life index PUFA (r =-0.418, p = 0.000) and Calculus Index (r =-0.158, p = 0,091). The better childrenâ€™s dental health status the betterÂ  the childâ€™s quality of life. It is therefore advised to care for dentalÂ  and mouth health in children so thatÂ  can increase the quality of life .
Rural Poverty, Participation and Poverty-Reduction Strategies in Nigeria
Authors: Akindola Rufus Boluwaji , Ehinomen Chris O.
Published: September 2019

Despite Nigeria’s abundant oil, gas and other natural resources, the experience of the majority of its population in rural areas has been, and still is, one of abject poverty. Nigerians remain poor because of the failure of successive governments to manage the country’s enormous wealth effectively. Although poverty is equally widespread in urban areas, poor economic and social policies have aggravated the extent of poverty in rural areas. This article utilises a historical analysis technique to examine the nature of rural poverty in Nigeria and also the failure of the government’s poverty-reduction strategies. Information was sourced from previous studies, reports of government agencies and institutions, the World Bank, and relevant journals articles. The researchers have found that the limited understanding of the nature of poverty, and the failure to engage the rural poor and the wider community in decision-making processes, especially relating to poverty analysis, have been important factors that have contributed to the failure of past poverty-reduction strategies in the country. The researchers come to the conclusion that involving the poor is placing them at the centre of their own development process.

Published: September 2019

Resumo: Este trabalho se propôs de forma narrativa a revisar na literatura estudos que envolvem a utilização do ensino à distância em odontologia no Brasil, quais são suas metodologias e as ferramentas desenvolvidas para aplicação na graduação e pós-graduação. A grande maioria dos cursos de atualização “via internet” são em sua grande maioria transcrições do ensino presencial com formatos de alta acessibilidade e baixa interatividade. Existe uma oferta mínima de cursos de atualização e especialização em Odontologia na modalidade à distância. Dos agentes deste novo processo, os alunos de graduação estão capacitados a utilizar ferramentas para educação à distância e obtêm um melhor aproveitamento do curso com elas. O docente, entretanto, ainda necessita de dimensão técnica básica, aprender a utilizar as ferramentas, para desenvolver o curso à distância e do aspecto pedagógico, atuar como facilitador e mediador do processo de ensino-aprendizagem deixando de ser o centro dele.

CONSIDERATION OF THE VALIDITY OF THE STATISTICAL CHARACTERISTICS OF pH IN SURFACE WATERS
Authors: Korobov V. B. , Miskevich I. V. , Lokhov A. S. , Seredkin K. A.
Published: September 2019

Abstract: pH is one of the most important parameters characterizing the state of water systems. The arithmetic mean values of samples are often used when averaging serial pH measurements in water bodies, as is usually done for other characteristics of the state of the natural environment (temperature, salinity, oxygen concentrations, suspended solids, etc.). However, in this case such an operation is illegal, since the addition of logarithms, which by definition are pH, is non-additive. The authors conducted a study to determine the extent to which pH variability in natural objects such an operation would not distort the results. For this, several samples of the pH index were generated in various ranges of its theoretically possible and natural variability. It was established that with pH variability of less than a unit characteristic of marine pH values, the statistical characteristics of the indicator and [H+ ] concentrations differ slightly, and the medians of the samples coincide. It is concluded that with such ranges characteristic of the waters of the oceans, there is no need to recalculate previously obtained results. However, for the estuaries of rivers flowing into tidal seas, as shown by field measurements, the pH variability in the mixing zone of sea and river waters is several times higher. Similar situations may occur when heavy precipitation falls on the water surface, as well as during floods. In these cases, a simple averaging of the pH values will no longer be correct. In such cases, the use of other averaging algorithms and the choice of stable statistical characteristics are required.

Authors: Tatarskiy A. Yu. , Volynin A. F.
Published: September 2019

Abstract: at present, the range of tasks solved by geophysical methods is expanding. This is facilitated by the progress in the development of geophysical equipment, methods for performing field work and data processing. At the same time, the conditions of research are complicated. Often it is the site of industrial facilities or urban areas. The main factors complicating the implementation of the geophysical researches at urban areas are the high level of industrial noise and solid coverage. The article discusses the possibility of using resistance technology with 2D data inversion when solving engineering problems in urban areas. The conditions of the use of the measurement technique with capacitive electrodes for approximation by grounded electrode array at a direct current are shown. The results of the comparison of the dipole-dipole method with capacitive electrode array and its equivalent with galvanic grounded electrodes are presented. To assess the effectiveness of using of the capacitive electrodes array for solving engineering tasks in the city, the authors carried out researches on a site of regularly emerging subsidence of pavement in the center of St. Petersburg. According to the research results, a 2D resistivity section of the pavement deformation was constructed. The results were interpreted using geological information. The studies revealed a spatial correlation of the identified anomalies of specific electrical resistances with the local site of the embankment pavement destruction. The possible causes of the identified anomalies are described. The results of electrical prospecting with linear capacitive electrodes can be used for detailing engineering geological structure of urbanized areas.

Published: September 2019

Cultural practice of nutritional consumption during pregnancy can affect the quality of maternal and fetal health. Mothers need sufficient nutrients to be able to adapt of pregnancy changes. The growth and development of the fetus is depends on the mother. Some cultural practices believe that some types of food have a bad impact on both the mother and the fetus, so that the food is prohibited to be consumed during the pregnancy period. The purpose of the study was to explore the types of prohibited foods during pregnancy in Pulau Godang Kari, Kuantan Singingi. This is an ethnographic research was conducted on 15 informants consisting of pregnant women, families, midwife and traditioanl birth attendance. Data collection used direct observation, focus group discussions and interviews that are analyzed by using content analysis. Prohibition of certain types of food based on the type of food that was believed that the properties are not good, so it was believed to have a bad effect on the mother and fetus. The implementation of cultural practices related to dietary restrictions is still being carried out, because of the belief that something unwanted will happen if you choose to consume these foods. Therefore, health workers must be able to provide culturally sensitive health services, so they can provide alternative food choices to fulfill nutritional needs during pregnancy period

On the Linear Geometry of Lanthanide Hydroxide (Ln—OH, Ln=La-Lu)
Authors: Harb Hassan , Thompson Lee , Hratchian Hrant
Published: September 2019

Lanthanide hydroxides are key species in a variety of catalytic processes and in the preparation of corresponding oxides. This work explores the fundamental structure and bonding of the simplest lanthanide hydroxide, LnOH (Ln=La-Lu), using density functional theory calculations. Interestingly, the calculations predict that all structures of this series will be linear. Furthermore, these results indicate a valence electron configuration featuring an occupied sigma orbital and two occupied pi orbitals for all LnOH compounds, suggesting that the lanthanide-hydroxide bond is best characterized as a covalent triple bond.

Designing synthetic surrogates of functional proteins is an important, albeit challenging, task in the field of chemistry. A strategy toward the design of synthetic agonists for growth factors or cytokine receptors that elicit a desired signal activity has been in high demand, as such ligands hold great promise as safer and more effective therapeutics. In the present study, we used a DNA aptamer as a building block and described the strategy-guided design of a synthetic receptor agonist with fine-tuned agonism.

Retaining glycoside hydrolases cleave their substrates through stereochemical retention at the anomeric position. Typically, this involves two-step mechanisms using either an enzymatic nucleophile via a covalent glycosyl enzyme intermediate, or neighboring group participation by a substrate-borne 2-acetamido neighboring group via an oxazoline intermediate; no enzymatic mechanism with participation of the sugar 2-hydroxyl has been reported. Here, we detail structural, computational and kinetic evidence for neighboring group participation by a mannose 2-hydroxyl in glycoside hydrolase family 99 endo-α-1,2-mannanases. We present a series of crystallographic snapshots of key species along the reaction coordinate: a Michaelis complex with a tetrasaccharide substrate; complexes with intermediate mimics, β-1,2-aziridine and β-1,2-epoxide; and a product complex. The 1,2-epoxide intermediate mimic displayed hydrolytic and transfer reactivity analogous to that expected for the 1,2-anhydro sugar intermediate supporting its catalytic equivalence. Quantum mechanics/molecular mechanics modelling of the reaction coordinate predicted a reaction pathway through a 1,2-anhydro sugar via a transition state in an unprecedented flattened, envelope (E3) conformation. Kinetic isotope effects for anomeric-2H and anomeric-13C support an oxocarbenium ion-like transition state and that for C2-18O (1.052 ± 0.006) directly implicates nucleophilic participation by the C2-hydroxyl. Collectively, these data substantiate this unprecedented and long-imagined enzymatic mechanism.

The Properties of α-Synuclein Secondary Nuclei are Dominated by the Solution Conditions Rather than the Seed Fibril Strain
Authors: Peduzzo Alessia , Linse Sara , Buell Alexander
Published: September 2019

α-synuclein (α-syn) is a natively unfolded protein predominantly localized in the presynaptic terminals of neurons. It has been shown that α-syn fibrils are the major component of abnormal neuronal aggregates known as Lewy bodies, the characteristic hallmark of Parkinson’s disease. Amyloid fibrils arise through primary nucleation from monomers, which in the case of α-syn is accelerated by suitable surfaces with an affinity for the protein, followed by the elongation of the nuclei by monomer addition. Secondary nucleation, on the other hand, corresponds to the formation of new fibrils when it is facilitated by pre-existing fibrils. While

α-synuclein (α-syn) is a natively unfolded protein predominantly localized in the presynaptic terminals of neurons. It has been shown that α-syn fibrils are the major component of abnormal neuronal aggregates known as Lewy bodies, the characteristic hallmark of Parkinson’s disease. Amyloid fibrils arise through primary nucleation from monomers, which in the case of α-syn is accelerated by suitable surfaces with an affinity for the protein, followed by the elongation of the nuclei by monomer addition. Secondary nucleation, on the other hand, corresponds to the formation of new fibrils when it is facilitated by pre-existing fibrils. While it is well-established that the newly added monomer in the process of fibril elongation adopts the conformation of the monomers in the seed, often called templating, it is still unclear under which conditions fibrils formed through secondary nucleation of monomers on the surface of fibrils copy the structure of the parent. Here we show by biochemical and microscopical methods that the secondary nucleation of α-syn, enabled at mildly acidic pH, leads to fibrils that structurally resemble more closely those formed de novo under the same conditions, rather than the seeds if these are formed under different solution condition. This result has important implications for the mechanistic understanding of the secondary nucleation of amyloid fibrils and its role in the propagation of aggregate pathology in protein misfolding diseases.
Geometric Analysis of Shapes in Ion Mobility-Mass Spectrometry
Authors: Haler Jean , Béchet Eric , Far Johann , De Pauw Edwin
Published: September 2019

Experimental ion mobility-mass spectrometry (IM-MS) results are often correlated to three-dimensional structures owing to theoretical chemistry calculations. The bottleneck of this approach is the need for accurate values, both experimentally and theoretically predicted. Here, we analyze experimental and theoretical collision cross-section (CCS) evolutions instead of interpreting absolute CCS values. Experimentally, the CCS trends of synthetic homopolymers are analyzed as a function of increasing degrees of polymerization (DP) for different charge states. Then, shape evolutions of modeled shape deformations yield theoretical CCS trends, calculated using new software called MoShade (projected area calculations). The shapes are modeled using computer-aided design software where we considered only geometric factors: no atoms, chemical potentials or interactions are taken into consideration to make the method orthogonal to classical methods for 3D shape assessments using time-consuming computational chemistry. We are able to correlate modeled shape evolutions to experimentally-obtained polymer CCS trends. We thus modeled the apparent volume or envelope of their ion-drift gas interactions as sampled by IM-MS. Moreover, the CCS of convex shapes could be directly related to their surface area. The relation seems to hold even for concave shapes which could be correlated to geometry-optimized structures of ions obtained by conventional computational chemistry methods. Modeling beads-on-a-string shape evolutions allows extracting precise dimension relations between two homopolymers, without modeling any chemical interactions.
The Missing Label Problem: Addressing False Assumptions Improves Ligand-Based Virtual Screening
Authors: Martin Lewis , Bowen Michael
Published: September 2019

Ligand-based virtual screening (LBVS) uses machine readable representations of chemicals to learn a mapping function that can predict binding interactions with protein labels. Because it is highly scalable it is increasingly used in drug development in academic and pharmaceutical contexts. We have identified assumptions commonly used in LBVS that are false, which collectively can be described as the missing label problem. Firstly, many of the binding interactions in the bioactivity databases typically used to train LBVS models have never been tested before, but the absence of a label is interpreted by most models as a true negative. Secondly, many proteins have multiple binding sites with unrelated shapes but the associated ligands are grouped together under the one protein label. These assumptions frustrate the ability of the model to learn a correct mapping function. Here we use statistical techniques to predict values for the missing labels and binding sites and show how this improves the ability of LBVS models to rank ligands correctly. In the process we introduce a new technique for removing bias during model evaluation based on data blocking from experimental design theory. All data and code for analysis and generating figures is publicly available on github (https://github.com/ljmartin/Missing_label_problem).
Comparison Between SMILES-Based Differential Neural Computer and Recurrent Neural Network Architectures for De Novo Molecule Design
Authors: Johansson Simon Viet , Prykhodko Oleksii , Arús-Pous Josep , Engkvist Ola , Chen Hongming
Published: September 2019

In recent years, deep learning for de novo molecular generation has become a rapidly growing research area. Recurrent neural networks (RNN) using the SMILES molecular representation is one of the most common approaches used. Recent study shows that the differentiable neural computer (DNC) can make considerable improvement over the RNN for modeling of sequential data. In the current study, DNC has been implemented as an extension to REINVENT, an RNN-based model that has already been used successfully to make de novo molecular design. The model was benchmarked on its capacity to learn the SMILES language on the GDB-13 and MOSES datasets. The DNC shows improvement on all test cases conducted at the cost of significantly increased computational time and memory consumption.

"Conocimiento" en un Sistema de Drones Levantando una Carga
Authors: Suárez Joel , López Morales Virgilio , Juárez Vargas César Eduardo
Published: September 2019

El sistema de ecuaciones diferenciales asociado al problema de levantar y transportar una carga por medio de un grupo de drones tiene una estructura compleja que presenta acoplamiento, y una serie de  transformaciones lineales y no lineales sobre diversas variables dinámicas. Esencialmente, se observan transformaciones del tipo rotacional (a través de la presencia de matrices skew–symmetric), traslacional (transformación afı́n) y proyectivas (por medio de matrices de rotación de sistemas de coordenadas locales); lo que permite lanzar el ansage de que el “conocimiento” (entendido como información puesta en acción)  que un sistema tiene se hace patente por medio de la manipulación de información a través de  transformaciones lineales o no lineales. El sistema de drones que transportan una carga resulta interesante porque, además de lo anteriormente escrito, se presta para introducir la idea de “intencionalidad” del sistema para lograr un objetivo, y de que ésta también tenga una interpretación como transformación.Este trabajo introduce los primeros pasos en el estudio del concepto de “conocimiento” en esta dirección. En este sentido, el giro interpretativo (basado en la idea de pensamiento lateral) que se le da a la dinámica del sistema es único y prometedor.

Information Literacy Strategies Used by Second- and Third-Year Biology Students
Authors: Lantz Catherine , Dempsey Paula R
Published: September 2019

Results from focus groups with 23 second- and third-year biology students revealed gradual gains in information literacy (IL) abilities and dispositions needed for them to join the community of scientific practice as laid out in the ACRL Framework for Information Literacy for Higher Education. Students were consumers of information and not yet producers of information. They interacted often with primary research articles but struggled to use research tools effectively; remembered active learning vividly; and relied on video resources, Google, and discussions with peers and instructors to define terms and understand results. Findings support the value of collaboration between librarians and science faculty to incorporate IL skills in the process of scientific discovery.
