Authors: Dantas Sulivan Pereira
Published: November 2021

A climatologia geográfica como conteúdo da disciplina de Geografia traz consigo diversas situações que podem ser abordadas dentro da sala de aula, assim como do ambiente escolar. Entretanto, entre as várias dificuldades encontradas pelo docente de Geografia, os desafios são: a abordagem dos conteúdos da climatologia de acordo com as suas mais recentes concepções, diante dos recursos (in) disponíveis na maioria das escolas da rede pública de ensino fundamental, e o esforço intelectual a ser feito para sua conotação geográfica já. Através da pesquisa qualitativa de Estudo de Caso nos sextos anos do Ensino Fundamental da Escola pública do município de Fortaleza/CE foi possível mostrar se há de fato a utilização de recursos didáticos ou não na sala de aula, onde tivemos como resultado dificuldades quanto ao ensino de Geografia e aos conteúdos de Climatologia. Assim foram listados alguns conteúdos de clima e a partir de entrevistas com os alunos do ano supracitado foi possível identificar que eles têm maior dificuldade em definir e diferenciar Tempo e Clima, expressando vários motivos.

Published: November 2021

Viral respiratory infections are a leading cause of illness and mortality in all age groups
worldwide. The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) that causes Coronavirus
disease 2019 (COVID-19) has spread throughout the world, igniting the twenty-first century’s
deadliest pandemic. Research has shown that phages, which are bacterial viruses, can help
treat viral infections with the effect on the immune system and their antiviral activity. Phages have
specific activity and affect only the target without any side effects on other parts of the human
body. Human phage-related diseases have not been reported yet; therefore, phages can be a very
safe treatment, especially in many viral infections. The results of clinical studies have a promising
future regarding the use of phages. It is possible that the phages display technique aided in the production
of SARS-CoV-2 specific antibodies against its viral protein, which prevented the virus
from binding or replicating and preventing secondary microbial infections, which have been linked
to many patient deaths. Furthermore, an effective antiviral vaccine can be produced by using the
same technique. Given the growing number of coronaviruses cases around the world, in the present
paper, we review the possible mechanisms of phages against the COVID-19 disease and the
method that may be a solution to eliminate the virus.
The Effect of Dicarboxylic Acid Catalyst Structure on Hydrolysis of Cellulose
Model Compound D-Cellobiose in Water
Authors: Amarasekara Ananda S. , Fernando Harshica
Published: November 2021

Background:

Polycarboxylic acids are of interest as simple mimics for cellulase enzyme catalyzed depolymerization of cellulose. In this study, DFT calculations were used to investigate the effect of structure on dicarboxylic acid organo-catalyzed hydrolysis of cellulose model compound D-cellobiose to D-glucose.

Methods:

Binding energy of the complex formed between D-cellobiose and acid (Ebind), as well as glycosidic oxygen to dicarboxylic acid closest acidic H distance were studied as key parameters affecting the turn over frequency of hydrolysis in water.

Result:

α-D-cellobiose - dicarboxylic acid catalyst down face approach showed high Ebind values for five of the six acids studied; indicating the favorability of down face approach. Maleic, cis-1,2-cyclohexane dicarboxylic, and phthalic acids with the highest catalytic activities showed glycosidic oxygen to dicarboxylic acid acidic H distances 3.5-3.6 Å in the preferred configuration.

Conclusion:

The high catalytic activities of these acids may be due to the rigid structure, where acid groups are held in a fixed geometry.

Authors: Yasynetskyi Mykola , Banyra Oleg , Nikitin Oleg , Ventskivska Iryna , Kozlov Vadym , Kvach Mykola , Borzhievskyy Andrii
Published: November 2021

Background:

Trichomonas vaginalis (TV), Mycoplasma genitalium (MG) and Ureaplasma
urealyticum (UU) are common sexually transmitted infections (STIs) that are diagnosed in infertile
couples (cps). In cases with their simultaneous presence in a patient (mixed STI, MSTIs),
treatment is complicated by the different sensitivity of microorganisms to antibacterial drugs. Moreover,
in cases of complicated infections, the empirical treatment should be started before obtaining
the results of drug susceptibilities.

Objective:

The objective of the current study is to find the effective and well-tolerated combination
of drugs for the empirical antibacterial treatment of mixed STIs presented by TV, MG and UU in
infertile couples. We also aimed to establish the influence of mixed STIs on semen quality.

Method:

Our prospective study included 154 infertile couples (308 patients) with confirmed symptomatic
MSTIs in one of the couples caused by the simultaneous presence of TV, MG and UU. All
couples were randomized on three groups for empirical treatment: Group 1 (n=49 cps, 98 pts) who
were treated by initial prescribing of anti-trichomoniasis drug Secnidazole, 2.0 g po followed by
Azythromycin 500 mg on day 1 continuing by 250 mg on days 2-7; Group 2 (n=52 cps, 104 pts:
Secnidazole, 2.0 g po followed by Josamycin 1000 mg bid for 12 days); Group 3 (n=53 cps, 106
pts: Secnidazole, 2.0 g po followed by Moxifloxacin 400 mg once daily for 12 days). The endpoints
were clinical and microbiological cure rates as well as the frequency of side-effects in analyzed
groups. We determined the basic parameters of the spermogram and Deoxyribonucleic acid
(DNA) fragmentation levels in 59 patients with MSTIs before and at the 3rd, 6th and 9th month after
pathogens eradication comparing them with results in 63 healthy sperm donors.

Result:

After the treatment, clinical cure rates in analyzed groups were 82.6% (Group 1) vs.
96.1% (Group 2) vs. 92.3% (Group 3). Microbiological cure rates (UU+MG) were 73.9% vs.
97.1% vs. 84.5% correspondingly (p < 0.05). TV microbiological cure rates were 97.8% vs. 98.0%
vs. 96.1% (p>0.05). Side-effects were registered in 28.6% vs. 12.5% vs. 18.9% cases correspondingly
(p<0.05). In MSTIs patients, we registered the increasing DNA fragmentation rates, leucocytes
count and decreasing semen volume, motility, vitality, sperm concentration, total spermatozoa
number and number of spermatozoa with normal morphology. At the 6th month after complete
pathogens eradication, these parameters approached normal values.

Conclusion:

At the present time, the combination of Secnidazole+Josamycin can be considered the
most effective and well-tolerated for the empirical treatment in patients with MSTIs presented by
TV, MG and UU. Complete eradication of these MSTIs in males improves their semen parameters.

Authors: Irawan Bambang , Hidayat Muhammad
Published: November 2021

Pandemi global Covid-19 memberikan dampak kehidupan manusia, mulai dari dampak sosial sampai dengan tata laksana pemerintahan. Selain berkutat pada pengendalian penyebaran penyakit, pemerintah di seluruh dunia juga menghadapi ancaman lain yakni penyebaran informasi palsu terkait Covid-19. Distorsi informasi ini pada gilirannya justru menghambat upaya pemerintah dalam menangani dampak pandemi dan menambah masalah baru. Untuk itu penyampaian informasi yang benar dan tepat sasaran menjadi penting dalam upaya penanganan pandemi. Pada titik ini, peran e-government dituntut lebih dari sekadar memindahkan proses bisnis pemerintah dari luring ke daring. Evaluasi dari situs web resmi pemerintah ditujukan untuk menilai apakah situs web tersebut mampu mendukung tujuan-tujuan pemerintahan serta mendukung terwujudnya Good Governance. Penelitian ini akan mengevaluasi situs web resmi pemerintah yang memberikan informasi resmi terkait pandemi di Provinsi Kalimantan Timur melalui laman covid19.kaltimprov.go.id. Evaluasi ini menggunakan software bernama SortSite 5.3.5 yang akan berfungsi sebagai alat penguji otomatis berbasis daring. Adapun hal-hal yang diuji adalah errors, accessibility, compatibility dan standards yang juga disebut sebagai variabel pengukuran evaluasi situs web berdasarkan panduan W3C (World Wide Web Consortium). Berdasarkan hasil evaluasi yang didapatkan dari aplikasi SortSite 5.3.5 didapatkan data bahwa masalah terbanyak pada situs web covid19.kaltimprov.go.id berada pada variabel Accessibility dengan 85%, kemudian variabel compatibility dan standards dengan rata-rata 72% dan yang terakhir adalah variabel errors dengan rata-rata permasalahan sebesar 71% atau lebih tinggi daripada standar yang ditetapkan oleh W3C. Tentu saja hal ini merupakan temuan yang mengkhawatirkan dikarenakan banyaknya permasalahan secara teknis yang terdapat dalam situs web covid19.kaltimprov.go.id, yang pada gilirannya dapat mengakibatkan terhambatnya penyebaran informasi yang benar dan resmi terkait Covid-19.

Published: November 2021

A new analytic theory is developed for asymptotic stage of self-catalyzed growth of III-V nanowires (NWs) by molecular beam epitaxy (MBE), where NWs collect all group III atoms deposited from vapor. The shadowing NW length is derived which corresponds for the full shadowing of the substrate surface in MBE. The NW length and radius are derived depending on the effective deposition thickness and MBE growth parameters. It is shown that the NW length increases, and their length decreases with decreasing the array pitch and increasing the V/III flux ratio.

An experimental study of pulsations characteristics of the zone of flow separation arising at a small airplane-type UAV with a pushing two-blade propeller were carried out. The measurements were done in wind tunnel by unsteady pressure sensors and microphones built into the skin of the UAV for the test cases with and without a rotating propeller. A significant effect of the propeller on the level of pulsations was found. An increase of the incoming flow velocity led to a weakening of this effect. Analysis of the spectral data of the disturbances did not reveal a direct relationship between the propeller noise and the unsteady characteristics of the separation zone.

The Effectiveness of Pfizer-BioNTech and Oxford-AstraZeneca Vaccines to Prevent Severe COVID-19 in Costa Rica: Nationwide, Ecological Study of Hospitalization Prevalence (Preprint)
Authors: Rosero-Bixby Luis
Published: November 2021

BACKGROUND

The Costa Rican COVID-19 vaccination program has used Pfizer-BioNTech and Oxford-AstraZeneca vaccines. Real-world estimates of the effectiveness of these vaccines to prevent hospitalizations range from 90%-98% for two doses and from 70%-91% for a single dose. Almost all of these estimates predate the Delta variant.

OBJECTIVE

The aim of this study is to estimate the dose-dependent effectiveness of COVID-19 vaccines to prevent severe illness in real-world conditions in Costa Rica, after the Delta variant became dominant.

METHODS

This observational study is a secondary analysis of hospitalization prevalence. The sample is all 3.67 million adult residents living in Costa Rica by mid-2021. The study is based on public aggregated data of 5978 COVID-19–related hospital records from September 14, 2021, to October 20, 2021, and 6.1 million vaccination doses administered to determine hospitalization prevalence by dose-specific vaccination status. The intervention retrospectively evaluated is vaccination with Pfizer-BioNTech (78%) and Oxford-AstraZeneca (22%). The main outcome studied is being hospitalized.

RESULTS

Vaccine effectiveness against hospitalization (VEH) was estimated as 93.4% (95% CI 93.0-93.9) for complete vaccination and 76.7% (95% CI 75.0-78.3) for single-dose vaccination among adults of all ages. VEH was lower and more uncertain among older adults aged ≥58 years: 92% (95% CI 91%-93%) for those who had received full vaccination and 64% (95% CI 58%-69%) for those who had received partial vaccination. Single-dose VEH declined over time during the study period, especially in the older age group. Estimates were sensitive to possible errors in the population count used to determine the residual number of unvaccinated people when vaccine coverage is high.

CONCLUSIONS

The Costa Rican COVID-19 vaccination program that administered Pfizer-BioNTech and Oxford-AstraZeneca vaccines seems to be highly effective at preventing COVID-19–related hospitalization after the Delta variant became dominant. Even a single dose seems to provide some degree of protection, which is good news for people whose second dose of the Pfizer-BioNTech vaccine was postponed several weeks to more rapidly increase the number of people vaccinated with a first dose. Timely monitoring of vaccine effectiveness is important to detect eventual failures and motivate the public to get vaccinated by providing information regarding the effectiveness of the vaccines.

Published: November 2021

Lambung merupakan salah satu sistem pencernaan yang berfungsi sebagai media pengolah dan penyimpanan makanan, serta untuk menyingkirkan zat berbahaya dan menyerap zat baik bagi tubuh. Biasanya, sekolah dasar menggunakan torso sebagai alat bantu peraga organ lambung. Namun, hal ini sangat tidak fleksibel bagi siswa sekolah dasar yang memiliki keterbatasan jam belajar di sekolah. Oleh karena itu, perlu dikembangkan suatu sistem pembelajaran organ lambung yang dapat dipelajari kapan saja dan di mana saja. Pada makalah ini dirancang suatu aplikasi pembelajaran organ lambung berbasis Android dengan menerapkan Augmented Reality (AR). Untuk menjalankannya, pengguna perlu menginstal aplikasi terlebih dahulu, kemudian membuka aplikasi, memilih menu yang diinginkan, lalu mengarahkan smartphone ke arah marker yang sesuai sampai tampilan AR muncul. Berdasarkan hasil pengujian, aplikasi tidak dapat memunculkan objek AR dari organ lambung pada tempat yang gelap karena marker tidak terdeteksi. Jarak terbaik untuk deteksi marker yaitu pada rentang jarak 20 cm sampai 35 cm, dengan rata-rata delay 0,3 s pada kondisi indoor dan 0,45 s pada kondisi outdoor.

Cómo se siente el dolor no depende de la lesión corporal
Authors: Fajardo-Chica David
Published: November 2021

La experiencia del dolor suele caracterizarse por su temporalidad, localización, intensidad, por qué tan desagradable se experimenta y la manera particular en el que se siente (como “caliente”, “un latigazo”, “profundo” u “hormigueante”). Estas últimas son las cualidades sensoriales del dolor (csd). Discuto aquí la tesis representacionista según la cual las csd se explican por un contenido mental que describe la naturaleza del daño corporal. Desarrollo dos argumentos en contra de la regularidad que tal tesis supone entre las csd y la naturaleza de la lesión, y presento evidencia a partir del “Cuestionario del dolor de McGill”, un instrumento clínico para la comunicación del dolor. Concluyo que la lesión corporal y las cualidades sensoriales del dolor no covarían como supone esta forma de representacionismo.
El extraño criterio utilizado para crear “la Doxa” de Parménides
Authors: Cordero Nestor-Luis
Published: November 2021

En 1795, un filólogo de origen kantiano, G.G. Fülleborn, agrupó en dos “partes” los fragmentos recuperados del Poema de Parménides: “la Verdad” (frgs. 1–8.50) y “la Doxa” (frgs. 8.51–18; el frg. 19 fue descubierto después). Con pequeñas modificaciones, esta estructura se convirtió en clásica y se acepta hoy en forma unánime. Sin embargo, una lectura de cada fragmento en forma aislada no justifica dicha división, la cual se basa en una interpretación de Simplicio influida por Aristóteles, quien encuentra ya en Parménides un esbozo del dualismo platónico entre lo “sensible” y lo “inteligible”, inexistente en éste. Analizo aquí en forma crítica el criterio que emplea Fülleborn, anacrónico para el caso de un pensador preplatónico.

Vertebral osteomyelitis (VO) is an infection of the spine mainly caused by bacterial pathogens. The pathogenesis leading to destruction of intervertebral discs (IVDs) and adjacent vertebral bodies (VBs) is poorly described. The present study aimed at investigating the connection between infection and bone/disc metabolism in VO patients. 14 patients with VO (infection group) and 14 patients with burst fractures of the spine (fracture group; control) were included prospectively. Tissue biopsies from affected IVDs and adjacent VBs were analysed by RT-qPCR for mRNA-expression levels of 18 target genes including chemokines, adipokines and genes involved in bone metabolism. Most importantly, the receptor activator of NF-κB/osteoprotegerin (RANK/OPG) expression ratio was drastically elevated in both VBs and IVDs of the infection group. In parallel, expression of genes of the prostaglandin-E2-dependent prostanoid system was induced. Such genes regulate tissue degradation processes via the triad OPG/RANK/RANKL as well as via the chemokines IL-8 and CCL-20, whose expression was also found to be increased upon infection. The gene expression of the adipokine leptin, which promotes inflammatory tissue degradation, was higher in IVD tissue of the infection group, whereas the transcription of omentin and resistin genes, whose functions are largely unknown in the context of infectious diseases, was lower in infected VBs. In summary, similar expression patterns of pro-inflammatory cytokines and pro-osteoclastogenic factors were identified in VBs and IVDs of patients suffering from VO. This suggests that common immuno-metabolic pathways are involved in the mechanisms leading to tissue degradation in VBs and IVDs during VO.

This study was carried out in the dental school of Ahram Canadian University in Egypt to investigate the knowledge and compliance of senior students and interns toward infection control practices. A self‑administered questionnaire was employed with questions pertinent to the participants’ knowledge of risks in the dental settings, the practice of hand hygiene, the use of protective equipment, and the management of sharp injuries, among others. Although the knowledge and practice of the 240 surveyed participants were good; they were not up to the coveted standards. Despite being an integral part of their curriculum, an alarming percentage (19.6%) of the participants denied receiving knowledge about infection control instructions. Meanwhile, only 72.5% were aware of being at risk in the dental settings, and 78.3% confirmed their practice of hand hygiene. On the other hand, 84.6% of the surveyed participants confirmed the availability of protective equipment and 94.2% of them expressed their willingness to apply infection control measures in the future. The defects in the knowledge and practice mandate corrective actions to promote and upgrade the students’ compliance. Meanwhile, other gaps can be rectified via developing state-of-the-art communicative strategies. Efforts are warranted to enhance the attitude and motivate the students to conform to the protective safety measures. With all the infection control procedures already established in dental schools, the challenge lies in improving the students’ compliance with these recommendations.

Published: November 2021

Abstract: Plastics has become the necessity of our daily life. Its production and consumption has been rising rapidly due to its wide range of application in the domestic and industrial usage. But due to its non-biodegradable nature, it cannot be easily decomposed in the environment and hence is a major issue of Environment pollution. So, nowadays new technology is being used to treat the waste plastic by a known chemical reaction - pyrolysis. Under the pyrolytic conditions and cracking process, the plastic wastes can be decomposed into three different states thereby the converted product can be reused in different processes. The waste plastics consisting of high-density polyethylene (HDPE) was pyrolyzed using catalyst and the recovered crude was analyzed and used as flow improvers. The liquid hydrocarbons obtained from the Pyrolysis of waste polymer products was used as diluent to change the characteristics of crude oil. The aim of the research work is to evaluate the change in the flow when blended with the Crude oil of different place. The Crude oil was Blended with the recycled diluents were in different fractions of 5%, 15%, and 25% of diluent. The plastic pyrolysis oil were then tested in a with fractions of 5, 10 and 15 volume% of diluent and their performance and characteristics analyzed and compare with it.

Abstract: Everybody knows about the importance of water. Water is the only source which distinguish our planet compare to all the others. The demand of water increasing day by day due to population growth and economic development. While the global supply of available of fresh water is more than adequate to meet all the current and fore see able water demands, its spatial and temporal distribution are not. The severity of water have direct impact in future. All of us must find ways to remove these constraints. Both central and state governments has various programmes for water conservation and management. Water conservation programs increase irrigation potential and try to improve the water and food security situation in country. In India due to rapidly growing population increase the drinking water consumption and decrease rain fall. Due to poor management, ignorance, lacking of technologies and in the absence of responsibilities by the people the water problem arise in India. Here is the major focus on factors responsible for water pollution and waste water treatment, so that focusing the remedy for major water pollution and waste water treatment will help to conserve water and will be helpful for effective management of our precious water. There are numerous methods to reduce water losses and improve water conservation and management like harvesting rain water, fog and dew, mulching, contour farming, and some technologies like nitration, ion-exchange and chlorination method.
