ANFIBIOS Y REPTILES EN PARQUES RECREATIVOS ECOLÓGICOS DE LA CIUDAD DE MÉRIDA, YUCATÁN, MÉXICO
Authors: Nahuat Cervera Pedro Enrique
Published: October 2021

La urbanización genera una gran variedad de impactos al medio ambiente que se consideran entre las principales causas de la disminución de las poblaciones de anfibios y reptiles, sin embargo, las áreas verdes dentro y a los alrededores de las ciudades amortiguan este impacto y se consideran un refugio para la flora y fauna. Pese a esto, muy pocos estudios se han centrado en conocer las especies que habitan las áreas verdes urbanas, por lo que el objetivo de este trabajo fue caracterizar la riqueza de anfibios y reptiles en parques recreativos ecológicos de la ciudad de Mérida, Yucatán, México. Se realizaron visitas ocasionales diurnas y nocturnas en cinco parques dentro y a las periferias de la ciudad de Mérida, implementando la inspección por encuentros visual por tiempo limitado. Para completar el listado de especies se revisó la plataforma iNaturalist. Se determinó su distribución y su estatus de conservación según la normatividad mexicana e internacional, y se evaluó la asociación entre localidades con base en la ocurrencia de especies. Durante el trabajo de campo se registraron 37 especies, donde 10 fueron anfibios y 27 reptiles. En adición, se obtuvieron tres especies más por medio de la plataforma iNaturalist. Siete especies se consideraron endémicas de la Península de Yucatán, y seis se consideran no nativas de esta región. Nueve especies se encuentran en la Norma Oficial Mexicana NOM-059-SEMARNAT-2010 y tres poseen un alto puntaje de vulnerabilidad ambiental. Se observó una asociación entre los parques ubicados a la periferia y los parques inmersos en la ciudad. Es importante considerar a las áreas verdes inmersas en las áreas urbanas como hábitats para los anfibios y reptiles, sin embargo, también es necesario evaluar su efectividad en la conservación de estas especies.

SEGREGACIÓN DE HÁBITAT DE INDIVIDUOS ADULTOS Y JUVENILES DEL GARROBO Ctenosaura similis EN EL PARQUE NACIONAL SANTA ROSA, GUANACASTE, COSTA RICA.
Authors: Mora José Manuel
Published: October 2021

Analizamos la distribución del garrobo Ctenosaura similis en tres tipos de hábitat del Parque Nacional Santa Rosa, Costa Rica: área abierta, área boscosa y área administrativa (suburbana). Registramos 101 individuos de los que un 32.7% eran hembras, 19.8% machos y 47.5% de sexo indeterminado. Registramos 58 individuos adultos y 43 individuos juveniles. El número de individuos adultos fue diferente al número de individuos juveniles (X²=8.21, df=2, p=0.02). Igualmente, la distribución de individuos por edad y apertura del dosel fue diferente (X²=20.97, df=4, p= < 0.001). En contraste, la cantidad de individuos por edad y tipo de sustrato fue igual (X²=3.12, df=3, p=0.37), tanto los individuos juveniles como los adultos se encontraron mayoritariamente en el suelo. Concluimos que los garrobos se segregan por edad y tipos de hábitat. Es posible que esta segregación esté determinada por la disponibilidad de recursos alimentarios y características del hábitat.

El giro de la investigación universitaria hacia la acción pública: el debate sobre los Centros de Pensamiento en Colombia
Authors: Medina-Muñoz Lina-Rocío
Published: October 2021

Este artículo examina los debates que sostienen los miembros de la comunidad académica colombiana con respecto a la reorganización de la investigación universitaria en Centros de Pensamiento, con el propósito de categorizar las tensiones que han emergido como resultado de este proceso y establecer qué aspectos de la actual organización deberían ser transformados. Para analizar estos debates se diseñó una aproximación metodológica cualitativa que atiende a los principales conceptos propuestos tanto por la sociología de la ciencia como por los estudios de redes. En primer lugar, se realizó una breve descripción del marco normativo que reestructuró el Sistema Nacional de Ciencia y Tecnología a partir de los años noventa. Luego, se caracterizaron las tensiones surgidas alrededor de los cambios organizativos, documentándolas mediante entrevistas semiestructuradas y ejercicios de observación etnográfica. Finalmente, se discutieron los obstáculos que deberían ser removidos por una reestructuración organizativa, a fin de que los productos de investigación tengan mayor incidencia social. Este trabajo concluye que la participación de los académicos en equipos de investigación heterogéneos se percibe ahora como un factor diferencial para ampliar el impacto del conocimiento universitario en la esfera pública.

Authors: Finco George , Fiametti Karina , Salva E.A. da , Palú Fernando , Wancura João , Valério Alexsandra , Oliveira Jose
Published: October 2021

Monoacylglycerol (MAG) and diacylglycerol (DAG) are two natural
components found in most edible oils and fats. Conventional synthesis of
MAG and DAG is usually conducted by glycerolysis of triacylglycerol
(TAG) at high temperatures (above 200 °C) in the presence of an alkaline
catalyst. In this work, the synthesis of MAG and DAG using enzymatic
glycerolysis of olive oil was investigated using Tween 80 as surfactant,
n-butanol as co-surfactant and the novel lipase in free/liquid
formulation Lipozyme TL 100L as catalyst. Experimental design was used
to evaluate the effect of enzyme load and reaction temperature on the
feedstock conversion. Enzyme load and system temperature were
significant variables in the statistical design and the best condition
was found at 35 °C, 7.5 vol% of Lipozyme TL 100 and glycerol to oil
molar ratio of 2:1 with conversion of TAG at approximately 98 % after 2
h of process. A mathematical model based on the Ping-Pong Bi-Bi
mechanism was used to describe the reaction kinetics. The model
adequately described the behavior of the system and can be a useful tool
for the design of reactors in larger scales.
Brainwave Controlled, Robotic Intelligent Assistive Device for People with Spinal Injuries, Cerebral Palsy, Amputation, and Muscular Dystrophy
Authors: Shrivastava Aryansh
Published: October 2021

People with spinal injuries, cerebral palsy, amputation, muscular
dystrophy, etc. have little to no control of their hands or feet, and
many times they cannot even speak to express their thoughts. Individuals
with such impairments encounter extreme physical, social, and
environmental challenges in their daily lives, which, in turn, create
impediments to self-supported living and to opportunities to take part
in economic and social aspects of life. To help these people, there is a
need of a neuro bio signal-controlled, machine learning based system
that can interpret their thoughts in a meaningful way, helping people
with disabilities conduct daily activities, enabling them to improve
their quality of life and live independently.
Persuading Pre-Professionals to be Participant Observers: Reflections on Teaching Anthropology and Education to Professional Teacher Candidates
Authors: McDonough Graham
Published: October 2021

This paper explains how I design and teach an Anthropology and Education course within a professional teacher education program. After establishing how some teacher candidates might initially imagine that this course is irrelevant to their professional education, I argue that anthropological knowledge and being able to think anthropologically enables teacher candidates to become better teachers. Specifically, I argue that becoming a participant observer of one’s own and others’ practices provides an easily accessible crossover between an anthropological method and mindset, on the one hand, and teacher actions like instruction, observation, assessment, and reflective practice (Schön 1982), on the other. To support this claim, I describe how I teach teacher candidates concepts and theory from anthropology that are applicable to the study of education, and can be used to inform their work on a video ethnography of a classroom (Hester 2012) that I assign to develop their practice of professional participant observation. I then describe how I prepare teacher candidates to consider the context of that video, especially as it offers an encounter with ideological diversity within the teaching profession and schools. The conclusion explains how I encourage the candidates to continue using the participant observer concept to inform their professional work post-graduation.
The influence of traditional Chinese landscape architecture on the image of small architectural forms in Europe

Published: October 2021

The article analyzes the influence of traditional Chinese landscape architecture on the shaping of European small architectural forms and the influence of European architecture on contemporary Chinese architectural practice. The purpose of the article is to identify the features of the architectural mutual influences of Chinese and European cultures. The method of historical analysis, the method of comparative analysis and the graphoanalytical method are used. The lack of identity between the Chinese and European gardens and the park with the pavilions is proved at the different hierarchical levels. Two groups of European Chinoiserie style pavilions have been identified: which give a false idea of Chinese architectural traditions and which represent a simplified version of those traditions. There is noticed the influence of the traditional Chinese approach to the architectural objects placement in the natural environment on the development of the contextualism concept in Western architecture (since the 1960s) which proclaims its purpose to preserve the natural beauty of the site through careful design that relates to its surroundings. The concept of contextualism is now widely used in the design of small architectural forms in the urban environment and in the design of the architectural environment in general, both in Europe and in China. This is a clear example of mutual enrichment with the ideas of two civilizations, each of which preserves its own culture.

In this paper we present an approach to text area detection using binary images, Constrained Run Length Algorithm and other noise reduction methods of removing the artefacts. Text processing includes various activities, most of which are related to preparing input data for further operations in the best possible way, that will not hinder the OCR algorithms. This is especially the case when handwritten manuscripts are considered, and even more so with very old documents. We present our methodology for text area detection problem, which is capable of removing most of irrelevant objects, including elements such as page edges, stains, folds etc. At the same time the presented method can handle multi-column texts or varying line thickness. The generated mask can accurately mark the actual text area, so that the output image can be easily used in further text processing steps.
Skull stripping using traditional and soft-computing approaches for magnetic resonance images: a semi-systematic meta-analysis
Authors: Azam Humera , Tariq Humera
Published: October 2021

MRI scanner captures the skull along with the brain and the skull needs to be removed for enhanced reliability and validity of medical diagnostic practices. Skull Stripping from Brain MR Images is significantly a core area in medical applications. It is a complicated task to segment an image for skull stripping manually. It is not only time consuming but expensive as well. An automated skull stripping method with good efficiency and effectiveness is required. Currently, a number of skull stripping methods are used in practice. In this review paper, many soft-computing segmentation techniques have been discussed. The purpose of this research study is to review the existing literature to compare the existing traditional and modern methods used for skull stripping from Brain MR images along with their merits and demerits. The semi-systematic review of existing literature has been carried out using the meta-synthesis approach. Broadly, analyses are bifurcated into traditional and modern, i.e. soft-computing methods proposed, experimented with, or applied in practice for effective skull stripping. Popular databases with desired data of Brain MR Images have also been identified, categorized and discussed. Moreover, CPU and GPU based computer systems and their specifications used by different researchers for skull stripping have also been discussed. In the end, the research gap has been identified along with the proposed lead for future research work.

Published: October 2021

Perovskite solid solution (1-x)Pb(Zr0.52Ti0.48)O3-xY(Ta1/2Sb1/2)O3 ceramics
(abbreviated as PZT-YTS, where x = 0, 0.01, 0.02, 0.03, 0.04 and 0.05) were
synthesized by conventional solid state method. The phase structure,
microstructure and corresponding electrical properties were studied. X-ray
diffraction and Raman analyses show that tetragonal phase structure was
obtained in all ceramics at room temperature. Scanning electron micrographs
of the samples show uniform grain distribution and grain growth inhibition
with the increase of doping content. The dielectric permittivity,
dissipation factor, electromechanical coupling factor, Young modulus,
mechanical quality factor, piezoelectric charge constant, actual density and
piezoelectric voltage constant, for the ceramics with x = 0.04 were: ?r =
714.9, tan ? = 0.03345, KP = 0.635, Y = 10.528 ? 1010 N/m2, Qm = 622.254,
d31 = 74.738 ? 10?12 C/N, ?a = 7.67 g/cm3 and g31 = 10.477 ? 10?3 m?V/N,
respectively, which are optimal in comparison to other studied samples.
Effect of particle size of Y2O3-Al2O3 additives on microstructure and mechanical properties of Si3N4 ceramic balls for bearing applications
Authors: Zhang Jing , Wang Wenxue , Sun Feng , Zhang Weiru , Li Boheng , Zhang Mingshuai
Published: October 2021

Si3N4 ceramic balls were prepared by gas pressure sintering with Y2O3 and
Al2O3 as sintering additives. The effects of particle size of Y2O3-Al2O3
additives on densification, microstructure and mechanical properties of
Si3N4 ceramic balls were investigated. The reliability of Si3N4 ceramic
balls was evaluated through the Weibull modulus. The results showed that
Si3N4 ceramic balls containing nanosized Y2O3-Al2O3 additives have a higher
relative density and better comprehensivemechanical properties compared with
the samples containing microsized additives, with relative density of 98.9 ?
0.2%TD, Vickers hardness of 14.7 ? 0.1GPa, indentation fracture toughness of
6.5 ? 0.1MPa?m1/2 and crushing strength of 254 ? 8.5MPa. The more
homogeneous and extensive dispersion of the nanosized sintering additives in
the Si3N4 matrix is the main reason for the enhancement in density and
mechanical properties of the Si3N4 ceramic balls.
Tribological and aging behavior of hybrid Al 7075 composite reinforced with B4C, SiC, and TiB2
Authors: Aksöz S. , Kaner S. , Kaplan Y.
Published: October 2021

In this study, B4C+SiC/B4C +TiB2/SiC+TiB2 hybrid reinforcements were added to
Al 7075 matrix via the powder metallurgy method. The powders were subjected
to mechanical grinding for 240 min, as shown in the graphical abstract. The
hybrid composite powder structure produced by the mechanical grinding was
then placed in a vertical casting chamber and molten Al 7075 (main matrix)
was added to obtain the samples. Samples were dissolved for 1 h at 480 ?C,
and then aged at 120 ?C in 4-h increments (32 h in total). After the aging
process, the wear behavior of the samples was investigated. In the study,
FESEM images were examined for microstructural analysis, and hardness plots
of the aged samples were created depending on the time after the solutioning
treatment. The friction coefficient, volume loss, and worn surface images
were investigated to determine the wear behavior of the hybrid structures.
Results showed that the increased reinforcement rate and the reinforcement
size and type directly affected the hardness and wear behavior. In the
experiments, the highest hardness and wear resistance behavior were obtained
in the hybrid sample of 3% B4C + 3% SiC after 12 h of aging.

Published: October 2021

In this work, we traced structural transformations of an Al62.5Cu25Fe12.5
alloy, in which a quasicrystalline icosahedral phase (i-phase) can be
formed, upon spraying onto a substrate and consolidation from the powder
into the bulk state. The Al62.5Cu25Fe12.5 powder was obtained by gas
atomization and consisted of i-phase and ?-phase AlCu(Fe). The powder was
detonation sprayed (DS) and consolidated by spark plasma sintering (SPS)/hot
pressing (HP). During DS, the particles experienced partial or complete
melting and rapid solidification, which resulted in the formation of
coatings of a complex structure. The composite regions containing i-phase
were inherited from the powder alloy. The fraction of the material that
experienced melting solidified as ?-phase AlFe(Cu) in the coating. It was
suggested that the difficulty of obtaining i-phase upon post-spray annealing
is related to aluminum depletion of the alloy during DS. During SPS and HP,
the elemental composition of the alloy was preserved, while the exposure to
an elevated temperature led to phase homogenization. SPS and HP conducted at
700?C resulted in full densification and the formation of a single-phase
quasicrystalline alloy. The sintered single-phase alloy showed a higher
microhardness in comparison with the DS coatings.

The present investigation was carried out in Kharif 2019 (July to November) to estimate the relative contribution of various traits for total genetic variability present in aromatic landraces by Principal Component Analysis. Here 90 aromatic rice landraces along with six check varieties were evaluated for 13 quantitative characters by Principal Component Analysis. Principal Component Analysis showed that, out of 13 quantitative characters studied, only five principal components (PCs) exhibited more than 1.00 eigen value and showed about 81.62% cumulative variability among the traits studied. Out of the five principal components exhibiting more than 1.00 eigen value PC1 had the highest variability (25.12%) followed by PC2 (21.8%). The first principal component PC1 was positively contributed mainly by two characters viz., Grain Length and 1000 grain weight. The second principal component PC2 was contributed mostly by three characters like grain yield plant-1, panicle weight and spikelet fertility percentage. The third principal component PC3 is positively associated with panicle weight, grain yield plant-1 and spikelet fertility percentage. The fourth principal component PC4 is positively associated with spikelet fertility percentage, Grain Length/ Breadth ratio and fertile grains panicle-1. The fifth principal component PC5 is positively associated with total grains per panicle-1, grain width and 1000 grain weight. All the principal components were showing positive contribution for yield and its attributing traits. These variations can be exploited in crop improvement programme for developing high yielding varieties.
Coxsackie Virus Induced Graves’ Disease in an Immunocompetent Patient
Authors: Tang, DO, MPH Wesley , Das, MD Sulagna , Krudy, MD Zoltán
Published: October 2021

Enteroviruses, such as Coxsackie virus, have been implicated in the past as a pathogen associated with subacute thyroiditis, also known as de Quervain’s thyroiditis. Less commonly are viruses associated with autoimmune thyroid diseases such as Hashimoto’s thyroiditis and Graves’ disease. We present a case of a healthy 43 year old female who presented to the emergency department complaining of several months of weakness, nausea, loose bowel movements, anxiousness, and shortness of breath. Physical exam revealed tachycardia, tremors, and a non-tender thyroid gland to palpation. Skin exam showed a rash on the palms of her hands and soles of her feet bilaterally with dark papules, suggestive of Hand, foot, and mouth disease. Laboratory workup would reveal an undetectable thyroid stimulating hormone (TSH), and levels of T3 & T4 too high to quantify. Thyroid receptor antibodies would return as positive, diagnostic of Graves’ disease. Coxsackie virus (the causative agent of Hand, foot, and mouth disease) IgM titers also returned positive suggesting recent infection. Although the etiology of Graves’ disease is still not clear, this case report provides evidence that environmental triggers such as Coxsackie viral infection may be involved in its pathogenesis.

Rolul domiciliului în responsabilitatea socială a grupurilor transnaționale de societăți în Uniunea Europeană
Authors: Ungureanu Carmen Tamara
Published: October 2021

Ca efect al globalizării și al dezvoltării tehnologice, societățile din Uniunea Europeană (UE) și-au extins activitățile dincolo de piața unică europeană, formând grupuri transnaționale de societăți (GTS). GTS influențează economia statelor, această influență având atât aspecte pozitive, cât și negative. Responsabilitatea socială a societății (Corporate Social Responsibility) intervine în vederea înlăturării efectelor negative, care rezultă, în principal, din încălcarea drepturilor omului și din încălcarea regulilor privind protecția mediului înconjurător.

Forma clasică a GTS este aceea a unui grup de societăți în care o societate-mamă controlează filialele ei prin intermediul acțiunilor sau altor forme de proprietate. În această lucrare vom avea în vedere societățile-mamă sau societățile dominante din grup cu domiciliul/sediul în UE și cu filiale sau societăți dependente având domiciliul/sediul în state terțe UE. Vom arăta, utilizând mecanismele dreptului internațional privat, că societatea-mamă cu sediul în UE poate fi trasă la răspundere pentru prejudiciile cauzate de o filială a sa cu sediul într-un stat terț. Vom prezenta câteva spețe emblematice soluționate de instanțe din UE, care ilustrează schimbarea de paradigmă în spațiul UE cu privire la responsabilitatea socială a GTS. În final, vor fi analizate succint evoluțiile legislative la nivelul UE și a unor state membre.

Effectiveness of Pollutant Removal At the Wastwewater Treatment Plant in Goleniów
Authors: Jakubaszek Anita
Published: October 2021

The article assesses the efficiency of pollutant removal at the sewage treatment plant in Goleniów after modernization of the technological system. The extension and modernization of the existing installation resulted from the need to adapt the treatment plant to accept larger loads of pollutants, improve the parameters of treated sewage discharged to the receiver, and the poor technical condition of the equipment. Before the modernization of the treatment plant, an increase in the loads of COD, BOD5, and periodic total suspended solids in raw sewage was observed as well as a reduction in the efficiency of removing pollutants from the sewage. The efficiency of removing pollutants after modernization was in the range of BOD5 - 94.4 ÷ 99.8%, COD - 89.3 ÷ 98.9%, total suspended solids TSS - 95.3 ÷ 99.7%, total nitrogen - 64.1 ÷ 95.4%, and total phosphorus - 75.4 ÷ 99.4%.

Published: October 2021

Analysing environmental impacts of mining activities involves detailed studies of the interactions between technological activities/operations carried out in a mining operation and environmental components affected by them. In order to carry out a more complex environmental impact assessment caused by mining in the eastern part of Jiu Valley on soil and water 4 mining units have been considered in the study, these being mining unit Lonea, Petrila, and Livezeni with their belonging dumps.

Main objective of this research is to analyse the impact caused by mining activities in Eastern part of Jiu Valley by the method of impact networks according to the model “causes - pressures, depreciation of the quality of environmental factors – affected parameters - impact”. Thus, impacts caused by the mining industry were identified based on the top-down typology, being shaped impact networks for underground coal exploitation and sterile material storage on the surface. The metal content of the dumps was also analysed in order to assess the degree of metals soil enrichment compared to the reference concentration of a blank sample. The analysis of the influence of the local rainfall regime aims to highlight the leaching potential of heavy metals in the body of the dump and the possibility of analysing the scenarios of extension of the pollution phenomenon to the saturated area. The study is addressed to researchers, environmental engineers, hydrogeologists and geologists who want to deepen the study of transfer mechanisms of contaminants from dumps to watercourses receiving areas and their dispersion in unsaturated and saturated areas.
Motivation as an indicator of performance and productivity from the perspective of employees
Authors: Uka Ana , Prendi Ardita
Published: October 2021

Motivation plays a crucial role on employees’ performance. Though organizations have an interest in keeping the employees motivated at work, they do not always have the complete picture on what indeed motivates an employee. Scholars agree that money (including employees’ wages) significantly affects employees’ performance and productivity, but they do not unanimously place it among the strongest determinants of employee motivation. The main purpose of this work was to explore the factors influencing the true motivation of employees to enhance their performance and productivity at work. This study employed a quantitative research design based on data collected during the severe period of the COVID-19 pandemic. There were 110 participants, of which 38 (34.5%) males 72 (65.5%) females working in different companies in Albania. The results showed a moderate level of satisfaction and motivation at work and a significant correlation between the motivation and success of the company. Additionally, the data indicated that most of the participants were satisfied with the financial allowances, but that they aspired to have higher wages and better workplace conditions. Therefore, higher salaries, extra bonuses and the promotion in their role at work or recognition and appreciation seem to be very important motivational factors for the employees. Finally, this study proposes recommendations for companies on how to implement different strategies to increase employees’ motivation and enhance the business effectiveness. This study analyses data collected during the global pandemic and would serve as reference for periods associated with dire financial difficulty.
