Secure and Energy Efficient Data Transaction in WSN through SSCHS Routing Protocol
Authors: Soundarya R.
Published: October 2021

Abstract: Wireless sensor networks are widely used due to its usage and advantages because it can utilize in mission critical tasks. One of the major issues in WSN is reliable data delivery without any loss and to increase network lifetime by utilizing energy efficient process. The objective of this work is to increase network lifetime at the same time ensuring high packet delivery ratio. Clustering is one of the best methods to increase network lifetime, however election process of cluster head will consume energy and reduces network performance. Therefore in proposed work, energy efficient cluster based routing protocol has been implemented which includes residual energy and distance as major parameter to form cluster. Cluster head selection will be a static process, once cluster is formed cluster head will be selected through election process after transaction the residual energy in CH will be checked with the threshold value and same CH will again act as head this reduces cluster formation and election process. In addition to provide secure data transaction MD5 algorithm has been implemented. Attack based data loss is also reduced and concentrated in proposed work to achieve objective of this work. Keywords: (SSCHS) Secure static cluster head selection, network lifetime, cluster, MD5 and Static cluster head.
Failure Rate Prediction of Belt Conveyor Systems using 2-parameter Weibull distribution
Authors: Ogunmilua Olutayo Opeyemi
Published: October 2021

Abstract: The conveyor belt is one of the most operational critical equipment’s in the mining industry, they are mostly used in the transportation of crushed materials from the crushing station to where there’ll be further processed. Due to the increasing complexity of belt conveyor systems, managing their integrity has become even more difficult, as they are now used across various industries, environments and carry materials of different weight variations, leaving them susceptible to failures (1). This paper provides an industry specific knowledge on how Weibull analysis can be used to predict the failure rate of a conveyor belt system, using parameters such as the time to failure (TTF), installation and failure dates, as determinant parameters for the predictions. Several Weibull failure distributions and functions have been used to establish accuracy of results and to create comparisons on the different ways in which risk, unreliability and availability are quantified, using calculated values such as the Shape and scale parameter. The paper utilizes real world case studies in the area of mining, which sheds light on key component failures and their cut sets within the conveyor belt system (2) Keywords: TTF, TTR, Threshold parameter, Repair date, Shape parameter, B10, B15, B20, Scale parameter, ECA, CDF, PDF

Authors: Alfiyah Nur Inna , Tini Dwi Listia Rika
Published: October 2021

The election of a female village head in Lembung Timur is part of the maturity of the village community of Lembung Timur in seeing the meaning of gender equality in village leadership concerning leadership, especially in the decision-making process. Is it true that the appearance of a female village head to lead the village will be part of the better or more effective village leadership, which will lead to the decision-making process? This study aims to describe the role of female village heads in the decision-making process in Lembung Timur village, Lenteng district. The research method uses descriptive qualitative methods by utilizing qualitative data with descriptive elaboration. This study shows that, mainly in the decision-making process, Mrs. Faizah, as the village head in carrying out her role (manifest function), is only limited to the data collection stage. It can be said that Faizah has carried out her manifest function effectively because, from each stage of the decision-making process, she was done independently. The constraints faced are the lack of ability and experience and the occurrence of gender bias. Qualitatively, this study shows that the latent role or function of women's leadership in decision-making is not practical because the latent function performed in each decision-making process is played by Faizah's parents, namely Mr. Abdul Latif. Therefore, it is needed relating to the ability, skill, courage in playing the latent function for female village heads to break the hegemony of decision-making control by Mrs. Faizah's parents.
Humeanismo y leyes de la naturaleza: alcance y límites
Authors: Soto Cristián
Published: October 2021

Nomological Humeanism has developed into a research program encompassing several variations on a single theme, namely, the view that laws are statements about regularities that we find in nature. After briefly revisiting an early form of nomological Humeanism in Hume’s critique of the idea of necessary connection, this article critically examines Lewis’ two-fold approach based on Humean supervenience and the best system account. We shall point out three limits of nomological Humeanism, which are widely recognized in the literature: its inadequacy in view of physical theories, its explanatory circularity, and its purported anthropomorphism, all of which advocates of nomological Humeanism have attempted to overcome Humeanism (Jaag y Loew 2020, Loewer 2004 y Massimi 2018). Lastly, we will argue that nomological Humeanism fails to provide a suitable notion of modality for laws of nature. This latter issue continues to represent a live challenge for empiricism in the philosophy of physical laws.
Términos teóricos y teorías híbridas de la referencia
Authors: Serebrinsky Dalila , Borge Bruno
Published: October 2021

Both descriptivism and the causal theory of reference fail to account for the meaning of theoretical terms in a way consistent with scientific realism. Faced with this problem, hybrid theories of reference have been developed. They combine features of both descriptivism and the causal theory and seek to capture the advantages of each. In this work, we critically analyze two strategies to articulate hybrid theories of reference in the face of the problem of the meaning of theoretical terms. They are exemplified by the proposals of Psillos and Kitcher. We argue that neither of these strategies is successful in articulating the descriptive and causal elements in a genuine hybrid theory of reference that satisfies the standards of scientific realism.

Published: October 2021

This paper seeks to highlight the French philosopher Michel Foucault's contributions regarding his analysis of power. In this sense, the text proposes a conceptual transition around the ideas that could have interested the author within a digital context, integrating some notes and examples from the 2019 Chilean mobilizations.The article has an initial section that exposes genealogy as a way of approaching social reality. Then, it shows the social behaviors anticipation possibilities and their relationship with the information available on the web. Later, it renders an account of the algorithmic governmentality notion as a key to reading it in both normative structure and a political possibility to final state reflections.
El problema del seguimiento de reglas en Michael Oakeshott
Authors: González de Requena Farré Juan Antonio
Published: October 2021

The role of rules in our normative practices constitutes a relevant philosophical problema, mainly associated with Wittgenstein’s philosophy, but to which Michael Oakeshott has also attempted to answer. Not surprisingly, some scholars have found parallels between their conceptions of human practices and rule-following. Through an exegesis of the notion and uses of the rule in Oakeshott's works, this article aims to clarify the link between rule-following and normative authorization. In this way, it will be possible to to decide the originality and specificity of Oakeshott’s contribution and settle the question of the differences with the Wittgensteinian problematization of rule-following.
Using Padlets as E-Portfolios to Enhance Undergraduate Students’ Writing Skills and Motivation
Authors: Meletiadou Eleni
Published: October 2021

Despite the increasing support for the use of e-portfolios, research on its utility is just beginning to emerge. In terms of the current study, 200 students were asked to create digital portfolios with Padlet, share their e-portfolios via their Virtual Learning Platform (VLE), and ask for peer and lecturer feedback every time they completed a written task. Using a diagnostic test and their final assignment, students had to write a reflective report at the beginning and the end of an academic term. They also interacted every week using a forum created by their lecturer to enhance collaboration and peer support. At the end of each interactive feedback session, they had to reflect on their work and the feedback they received and post their self-reflections on the forum. Findings indicated that students managed to improve their writing performance significantly and enhance their motivation towards writing and learning in general due to this innovative alternative assessment method. This was evident from their final reflective reports, their focus group discussions, and the anonymous feedback they provided through Mentimeter. Students reported that they enjoyed this interactive experience which was both engaging and rewarding. However, students expressed their wish for more support when using IT tools and e-portfolios and asked to be guided to develop their writing and reflective skills and engage even more with their e-portfolios.

Comparison of Bleeding Profiles of Sugammadex and Neostigmine in Orthotopic Liver Transplantation
Authors: Liang Hong , White Launia , Chadha Ryan M , Renew J Ross
Published: October 2021

In the era of “fast-track’ liver transplantation (LT), neuromuscular
blockade (NMB) antagonists such as neostigmine or sugammadex are used to
achieve the restoration of neuromuscular function. While sugammadex
reverses NMB faster than neostigmine, it has been shown to prolong
prothrombin time (PT) and activated thromboplastin time (aPTT). However,
this agent’s impact on coagulation during LT is not understood. We
compare bleeding risk associated with sugammadex versus neostigmine
during liver transplantation. This is a single-center, retrospective
review of LT patients who received NMB antagonists intraoperatively
between 01/01/2015 to 05/31/2018 at Mayo Clinic in Florida. The primary
outcomes were postoperative day (POD) 0-1 bleeding events and POD 0
values of aPTT and INR. Total 241 patients were included, with 135
patients in the neostigmine group (NG) and 106 in the sugammadex group
(SG). POD 0-1 postoperative bleeding requiring transfusion occurred in
20% of NG versus 10.4% in SG. POD 0-1 re-operation for bleeding
occurred in 1.5% in NG vs. 0% in SG. POD 0 mean INR was 2.0±0.4 in
both groups. POD 0 mean aPTT was 45.5±7.9 in NG vs. 49.3±9.0 in SG. Our
retrospective study suggests that sugammadex is not associated with an
increased risk of bleeding compared to neostigmine use.

Objective To document longitudinal changes in brain development in
fetuses with congenital diaphragmatic hernia (CDH). Design Retrospective
cohort study Setting Single tertiary fetal surgery center Population
Fetuses with isolated CDH and at least two MRI-examinations (n=42
fetuses). Fifty-six fetuses who underwent MRI for a condition not
interfering with fetal brain development or fetuses from healthy
volunteers served as controls. Methods Biometry included biparietal and
fronto-occipital diameter, ventricular atrial width, transcerebellar
diameter, head circumference and width of the extra-axial space.
Cortical maturation was assessed using a qualitative and quantitative
grading system. 3D volumes were segmented for white matter, intra-axial
and extra-axial cerebrospinal fluid and cerebellum. Main outcome
measures Brain development on MRI with subjective and objective
assessment. Results The mean GA at first MRI was 28.0 ± 2.1 wks and at
the second 33.2 ± 1.3 wks. The mean GA in controls was 30.7 ± 4.2 wks.
At 28 weeks CDH fetuses displayed abnormal maturation grading
(p<0.003) and fissure depth (p<0.05). By 33 wks, the
brain grading indices were still abnormal (p<0.01), but
fissure depth measurements were in the normal range
(p>0.05). Also, the extra-axial fluid and the ventricular
volume were increased (resp. p 0.0054 and p 0.0243). There was no
difference in white matter or cerebellum volume (p>0.05).
Conclusions Brain development in CDH fetuses around 28 weeks appears to
be delayed. This is less prominent at 33 weeks. In addition, there was
an increase in ventricular and extra-axial space volume in the third
trimester.
John Henry Guy: A Man of Many Parts
Authors: Edwards John Richard
Published: October 2021

John Henry Guy worked in Britain and the United States throughout the first half of the twentieth century. He became the financial vice president of the M. Rumely Company of Indiana at just 31 years of age and, on his return to Britain, made a major contribution to the war effort while working as an accountant at the British Ministry of Munitions. It is also revealed that Guy took a broad view of accounting as a mechanism capable of achieving the more efficient use of resources by demonstrating its potential role within the domestic sphere. Throughout his career, Guy's religious convictions caused him great anxiety as he believed that the objectives of capitalism were fundamentally irreconcilable with the Christian principles that defined the legitimate conduct of daily life. Indeed, his own story demonstrates how easy it is for businesspeople to become associated with the shady side of commercial affairs.

Authors: Flynn Lauren N. , Julien Katie , Noureldin Amal , Buschang Peter H.
Published: October 2021

Objectives

To compare the efficacy of casein phosphopeptide (CPP)-amorphous calcium phosphate (ACP) MI Varnish (GC America, Inc, Alsip, IL) and ProSeal (Reliance Orthodontic Products, Itasca, IL) sealant in preventing the development of white spot lesions (WSLs) in orthodontic patients.

Materials and Methods

This prospective randomized clinical trial included 40 orthodontic patients 12–17 years of age. One group had sealants placed on their anterior maxillary teeth, with reapplications every 3 months. The other group had MI Varnish applied every 4–6 weeks. WSL formation and oral hygiene were evaluated at the initial appointment before bonding (T1) and 12 months later (T2). Standardized digital photographs were analyzed using the enamel decalcification index (EDI). Statistical comparisons were made using independent and paired-sample t-tests as well as chi-square tests.

Results

In this trial, 43% of patients and 15% of teeth developed new WSLs. Lateral incisors showed the highest incidence of decalcification and WSL formation. WSL formation and EDI score increases during treatment were significantly greater in the gingival region than in the mesial, distal, or incisal regions. Of the EDI scores at T2, 93.8% were 0 and 5.5% were 1. Poor oral hygiene at T2 showed a high positive predictive value (76%) for the development of WSLs. There were no statistically significant between-group differences for the development of WSLs.

Conclusions

MI Varnish and ProSeal sealant provided similar levels of protection during the first 12 months of fixed orthodontic treatment. The severity of the WSLs that developed was minimal. WSLs were most likely to develop on lateral incisors and in the gingival regions of teeth, especially among patients with poorer oral hygiene.

Authors: B Avinash
Published: October 2021

Coconut is one the major economic crop in India; a considerable amount of crop will be lost every year due to bud rot disease. Phytophthora palmivora is an omnipresent pathogen which causes many different diseases on a wide range of plants including bud rot of coconut. In the present investigation, we have successfully isolated bud rot disease causing fungus from the infected coconut plant samples. The isolated fungus was primarily identified by observing in microscopy further the same sample was sent for molecular identification. The presence of Phytophthora palmivora was confirmed in 18s rRNA sequencing. The growth of isolated fungus was effectively inhibited using biosynthesized Silver and Copper nanoparticles. The inhibition effects of nanoparticles against Phytophthora palmivora were observed excellent in dose-dependent manner. The silver nanoparticles synthesized using Silkworm fecal matter was shown superior inhibition activity towards Phytophthora palmivora compare to standard fungicide Fluconazole. Hence, these silver Nano particles could be successfully used in inhibiting the pathogenic fungus causing bud rot disease to coconut.

Published: October 2021

Because forest cover changes directly affect the sustainability of the forest value, they should be observed carefully. This study analyzed the spatial and temporal pattern of land use/land cover change (LULCC) along with the effects of some socio-economic factors such as forest crime rates, rural population change, and annual gross national product (GNP) on spatiotemporal change of forest dynamics between 1970 and 2015 in the Olur forest planning unit using ArcGIS software and Patch Analyst extension.The results showed that high forest areas increased by 47.14% between 1970 and 2015. Coppice stands completely transitioned to other cover types in 2015 due to the changing of management policy in the case study area. Based on landscape pattern, the total number of patches (NP) increased by 50.07%, and mean patch size (MPS) decreased by 31.88% during the period. Results indicated that the forest ecosystem became more sensitive as it turned into a more spatially fragmented structure, making continued efforts to maintain biodiversity and insure sustainability a challenge. Depending on the decrease in the rural population and economic growth, there was a serious decrease in forest crime rates. This study has shown that socio-economic factors can be effective on landscape dynamics besides management activities.
La prensa musical española de los 80 como perpetuadora del androcentrismo

Published: October 2021

La presente investigación se inscribe en la tradición de los estudios de género y examina, mediante un análisis cuantitativo y cualitativo, una de las principales revistas musicales de España, como fue Vibraciones. El objetivo principal es conocer el tratamiento informativo otorgado a la mujer en la prensa musical, mediante un análisis de contenido que nos permita descubrir cómo se transmiten los roles y estereotipos y de qué manera se configuran las identidades sexuales en la música de la década de los ochenta del siglo pasado. Una fecha clave con cambios sociales, políticos y económicos que propicia el contexto adecuado para llevar a cabo un análisis de cómo la prensa musical ha ido incurriendo en una discriminación de género hacia las artistas. Los resultados muestran una cifra ínfima de contenidos e imágenes protagonizados por mujeres, abundando los estereotipos físicos compatibles con una cosificación y revelando que el lenguaje de los medios es un arma de control que puede utilizarse para ejecutar opresión, impregnando la obra de las mujeres de una misoginia que trasciende fronteras culturales, geográficas y estéticas.
Relación del optimismo y el estrés con la calidad de vida en pacientes oncológicos: diferencias por tiempo de diagnóstico
Authors: Granillo-Velasco Ana Daniela , Sánchez-Aragón Rozzana
Published: October 2021

El cáncer representa una crisis personal y social en la vida de quienes lo padecen. Mientras que ciertas variables fungen como protectoras de la salud y la calidad de vida, otras pueden resultar de riesgo en una o más esferas, aunadas al tiempo que aquellos han tenido que hacer frente a la enfermedad, tanto si ya se han sometido al tratamiento, como si el diagnóstico es reciente. El presente estudio tuvo como objetivos identificar posibles diferencias en el optimismo, el estrés y la calidad de vida en función del tiempo de diagnóstico, y examinar la relación del optimismo y el estrés con la calidad de vida de los pacientes. Para ello, se empleó una muestra no probabilística de 196 pacientes adultos oncológicos (91 con un tiempo de diagnóstico máximo de 24 meses y 105 con un tiempo de diagnóstico mayor a dos años), quienes respondieron las escalas de Optimismo, de Estrés Percibido y de Estado de Salud Mental y Física SF-36. Los resultados evidencian, por un lado, que en los pacientes con un tiempo de diagnóstico de dos años o menos el optimismo, la calidad de vida y el estrés fueron menores que en quienes tenían un diagnóstico más antiguo; por otro lado, que el optimismo y el control del estrés se relacionan con menos afectaciones en el rol emocional y en una mayor vitalidad, siendo el descontrol del estrés lo que afecta más estos aspectos de la calidad de vida de los pacientes oncológicos.

Published: October 2021

Un diagnóstico de cáncer en un miembro de la pareja afecta de manera importante al otro. En esta travesía, ambos deben afrontar diversos retos físicos, psicológicos, económicos y de organización familiar que solo pueden ser resueltos si cuentan con el recurso relacional que caracteriza a las relaciones cercanas: la mutualidad. De acuerdo con algunos autores, este constructo se define por aspectos cognoscitivos, emocionales y conductuales, de los cuales el presente estudio retomó los dos últimos. Así, los objetivos de esta investigación fueron: 1) Examinar las posibles diferencias entre los pacientes con cáncer y sus parejas respecto a su mutualidad, correlatos emocionales (acompañamiento de la pareja, apoyo emocional y empatía y satisfacción con el apoyo recibido) y conductuales (compartir tiempo, frecuencia de sus relaciones sexuales, afectividad y corregulación de emociones negativas); 2) Explorar la relación entre los correlatos emocionales y los conductuales con la mutualidad experimentada por los participantes, y 3) Identificar los principales predictores de la mutualidad a partir de los correlatos mencionados. Participaron de manera voluntaria, confidencial y anónima 195 parejas heterosexuales, en las que uno de sus miembros había sido diagnosticado con algún tipo de cáncer, quienes respondieron a una batería de pruebas para cada correlato. Los resultados mostraron similitud entre ambos miembros de la pareja respecto a los aspectos estudiados, observándose relaciones significativas entre estos y la mutualidad, y finalmente se identificaron el acompañamiento de la pareja, la satisfacción con el apoyo cotidiano, la comunicación armoniosa, la afectividad y el compartir tiempo como sus predictores.
Socio-Cultural Space of the City: Ethno-Sociological Focus of Research
Authors: Madyukova S. А.
Published: October 2021

The article highlights the importance of the ethno-social focus of the research in the analysis of the socio-cultural space of the city. The use of the concept of "creolization" allows us to understand the socioculture of the city as formed on the basis of the ethnic composition of the city in а certain period of time, including а differentiated plurality of ethnocultures, not homogeneous in its structure, but implying an eclectic mixing of cultures into а socio-cultural integrity. Using the example of NovosiЬirsk, the article analyzes the influence of the ethno-confessional composition on the socio-cultural portrait of the city. Using the example of visually identifiaЬle "ethnically marked" objects of urban space (museums, temples) and events (holidays, festivals), the author comes to the conclusion that а complete meaningful understanding of the sociocultural space of modern NovosiЬirsk is impossiЬle without taking into account its ethno-social component.

А descrip­ tion of current proЬlems with understanding of the general meaning and context of situations in which narrow AI agents are found is presented. The definition of semantic supervised learning is given and its relationship with other machine learning methods is described. In addition, а thought experiment is presented, which shows the essence and meaning of supervised semantic learning.
Comparison and Analysis of Neural Solver Methods for Differential Equations in Physical Systems
Authors: Sim Fabio M , Budiarto Eka , Rusyadi Rusman
Published: October 2021

Differential equations are ubiquitous in many fields of study, yet not all equations, whether ordinary or partial, can be solved analytically. Traditional numerical methods such as time-stepping schemes have been devised to approximate these solutions. With the advent of modern deep learning, neural networks have become a viable alternative to traditional numerical methods. By reformulating the problem as an optimisation task, neural networks can be trained in a semi-supervised learning fashion to approximate nonlinear solutions. In this paper, neural solvers are implemented in TensorFlow for a variety of differential equations, namely: linear and nonlinear ordinary differential equations of the first and second order; Poisson’s equation, the heat equation, and the inviscid Burgers’ equation. Different methods, such as the naive and ansatz formulations, are contrasted, and their overall performance is analysed. Experimental data is also used to validate the neural solutions on test cases, specifically: the spring-mass system and Gauss’s law for electric fields. The errors of the neural solvers against exact solutions are investigated and found to surpass traditional schemes in certain cases. Although neural solvers will not replace the computational speed offered by traditional schemes in the near future, they remain a feasible, easy-to-implement substitute when all else fails.

Published: October 2021

Induction motors are widely used in industrial processes, vehicles and automation. Three-phase induction motors can be used for traction systems on electric locomotives. In this case, the speed control system is an important thing that must be applied to the propulsion system. This study aimed to test the indirect torque control for a Three-phase induction motor. A proportional integral (PI) controller was applied for speed controller. The indirect torque control system was modeled and simulated using PSIM software. According to the result, the control method showed a good performance. The speed could be maintained even the speed reference was changing or a load was applied. The steady state error of the speed response was just 0.1% with rise time around 0.06 s. The stator current went up to 39.5 A in starting condition. The stator current reached 12 A rms when the load of 10 Nm was applied. Then, the current rose to 15.7 A rms when the load was increased to 40 Nm and the current came down to 12.8 A rms when the load was decreased to 20 Nm.

Present policies of most Governments, with a few predictable exceptions, concentrate on the desperate need to get to zero carbon emissions as soon as possible. This is a necessary but not sufficient objective. There is strong evidence from the Keeling curve in figure 1, about the difficulty (Figure 1). Figure 1: But if we could reduce, carbon emissions to zero the concentration of atmospheric greenhouse gases will be what we have now plus what we will be emitting between now and the zero-emission date minus the amount taken up by the oceans. This means that typhoons, floods, droughts, bushfires, sea-level rise, Arctic ice loss and damage to coral will all be worse, perhaps much worse than now. If you think that present conditions are not acceptable you have to conclude that zero is not low enough. As well as reducing emissions we will HAVE TO remove greenhouse gases, probably with help from phytoplankton, and also do direct cooling a soon as we can and hopefully ramp it down as emissions reduce [1].

Soft tissue defects in the posterior ankle region with underlying Achilles tendon loss pose a reconstructive challenge to both Orthopaedic and Plastic surgeons. Such injuries can result in a severely debilitating sequelae for the patient, therefore reconstruction of the area must provide reliable function and durability with minimal complications and aesthetically pleasing results to enable normal foot wear. We describe the case of a twenty-seven year old male, who presented following a traumatic open rupture of the Achilles tendon and failed reverse sural artery flap. We performed a single stage composite soft tissue reconstruction with a free anterolateral thigh (ALT) flap and rolled vascularised Tensor Fascia Lata (TFL) for functional Achilles tendon reconstruction. The patient had no post-operative complications and was able to fully weight bear and dorsiflex his foot beyond ninety degrees at seven month follow-up. Whilst many options are available to reconstruct this area, we review the literature to illustrate the advantages of using this technique to achieve all of the above factors, and advocate for all foot and ankle surgeons to be aware of its use in their reconstructive repertoire.

Management of euryhaline species, such as Anguillid eel, is very important. Anguillid eel is an important economic fish which the partly of its life cycle spent in inland waters then migrates into the ocean for spawning. The objective of this study is to identify the morphological diversity and length-weight relationship of Anguillid eels in this province. The total of 148 individuals of elver and adult Anguillid eels were caught was identified using the comparison of ano-dorsal with total length parameter. Cluster analysis was obtained based on measurement of morphometric parameter. The current work used cluster analysis and dendrogram to group the population characteristic of Anguilla eel. It revealed that in the Jenggalu, Kungkai and Manna rivers of Bengkulu province, there are two groups of Anguilla eel with significant difference of ano-dorsal length. The value of the ano-dorsal varied from 2.56 ± 1.54 and 17.78 ± 1.33 for A.bicolor bicolor and A.marmorata, respectively. The length-weight relationships between total length (TL) and weight (W) for Anguilla bicolor and A.marmorata were found to be highly significant (r2 > 0.94, p < 0.001). The average value of 'b' for length and weight were higher than 3, i.e., 3.2677 and 3.4821 in A.bicolor and A.marmorata respectively which indicated a positive allometric growth trend of this species in the studied area.

Leachate treatment containing methylmercury (CH3Hg+) can be done by using biodegradation method. Bacteria used in methylmercury biodegradation of the bacteria Empedobacter brevis. This study aims to examine the ability of bacteria in degrading methylmercury in leachate and determine the value of ?max and Ks. The degradation process is done with variation of inoculum concentration and incubation time aerobically. The parameters analyzed were the decrease of methylmercury content in the biodegradation process. The results showed that biodegradation of methylmercury by the bacterium Empedobacter brevis at 15% inoculum concentration was the highest decrease efficiency of 81%. The values of ?max and Ks in the bacterium Empedobacter brevis were 0.994 per hour with a substrate concentration of 1.588 mg /l.

This research was conducted to (1) analyze the household waste management system, and (2) develop a strategy for household waste management in Suzuki Resident, Watutumou III Village, Kalawat District, getting in the era of "New Normal". This research uses quantitative methods with SWOT and AHP ((Analytical Hierarchy Process) techniques. The results show that the Waste Management system has Strength, such as the efforts to apply the 3R concept (Reduce, Reuse, and Recycle), waste management fees, and improvement, facilities and infrastructure, strengthening public understanding, support from local government and APBD (Local Government Budget) of North Minahasa Regency. The waste management system has several weaknesses, such as (1) lack of facilities and infrastructure for trash bins, the absence of 3R Landfill in residential areas, and limited human resource capacity toward waste management Opportunities which is faced by the waste management system including support for provincial government policies, facilitating the marketing of waste management products that are economically valuable. Threats which are faced are the increasing volume of waste, not optimal waste management and sorting, people behavior of littering. Based on these conditions, the priority of the Household Waste Management Strategy is to improve facilities and infrastructure to support waste management. The current strategy for developing a household waste management system is in quadrant IV that is diversifying the use of force and creating more opportunities. Strategic steps in managing household waste in Suzuki Resident, Watutumou III Village, Kalawat District, getting in the era of "New Normal, are improving existing facilities and infrastructure and adding to those that do not exist, optimizing waste retribution to support waste management costs, gathering support from stakeholders who related, strengthening public understanding of household waste management, and promoting efforts to apply the 3R concept in household waste management.

Aim – to assess the electromyographic features of the pelvic floor muscles and the sphincter apparatus in patients who underwent radical cystprostatectomy with the formation of an artificial bladder.The main study group consisted of 57 patients with muscle invasive bladder cancer who underwent a standard radical cystprostatectomy with ileocystoplasty. The study of the pelvic floor muscular bioelectric activity with computed electromyography (EMG) of the sphincter apparatus of the pelvic organs was carried out on a 2-channel computer electromyograph "NeuroTrac ™ MyoPlus4". The obtained results of the study of the bioelectric activity of the pelvic floor muscles showed a decrease in the amplitude of contractions in the Work Average mode by 42.1% (p≤0.001) for the perineal electrode, and by 35.7% (p≤0.05) for the rectal electrode, compared with the control group, which indicates a low contractility of the muscular diaphragm of the pelvis and may cause incontinence in patients with an artificial bladder. The average deviation over the entire duration of the session in Work mode in the group of patients with neobladder in channels A and B was 2.3 (p≤0.05) and 1.9 (p≤0.05) times higher, respectively, compared with control group. These data indicate an imbalance in the muscle tone of the pelvic floor in patients after extensive reconstructive intervention on the pelvic organs and can potentiate urodynamic disorders in the study group of patients. The average amplitude (Rest Average) of the activity of biopotentials in the resting state of the pelvic floor muscles along channels A and B is higher by 42.4% and 47.6% (p≤0.05), in comparison with the control group, which indicates insufficient relaxation and rest of striated muscles and sphincter. Despite the change in bioelectric potentials from the rectal electrode in the study group of patients, there were no signs of functional insufficiency of the anal sphincter, in contrast to the severity of urinary incontinence, which correlated and corresponded to the results of bioelectrical changes obtained through channels A and B, up to oscillations and loss of complete control. The EMG analysis of the pelvic floor muscles revealed characteristic changes in the biopotentials of the pelvic sphincters and indicated their relationship with the clinical features of the rehabilitation of this group of patients and the prospect of including the biofeedback method. It is a derivative form of the electromyographic signal in the treatment of incontinence in patients with neobladder.
