Aspectos teórico-metodológicos sobre la predicción de terremotos
Authors: Galbán Rodríguez Liber 
Published: August 2021

Los terremotos son los eventos de origen geológico que más transformaciones han generado en la historia de nuestro planeta. Si bien hasta la fecha los científicos no han podido predecir o pronosticar un terremoto, el conocimiento detallado de su génesis, la aplicación constante y combinada de las distintas teorías y métodos que se han diseñado para estas tareas; así como, la aplicación de un conjunto de estudios regionales, medidas organizativas y ejecutivas gubernamentales y locales, podrían reducir las altas situaciones de riesgo que hoy existen en varios países.
En esta ocasión se realiza un recorrido por las principales aristas de estas temáticas, partiendo de su marco conceptual, se revisan algunas de las principales teorías de predicción de terremotos inventadas por el hombre hasta la fecha, de manera que los científicos y decisores a nivel internacional puedan aplicar los preceptos metodológicos expuestos a su trabajo diario.

Published: August 2021

El objetivo de este artículo de reflexión es analizar la relación y el aporte que tienen los negocios inclusivos y la RSE vistos desde la cadena de valor, que vinculan a la base de la pirámide en los procesos productivos, que conlleven a la creación de valor y a la innovación como aporte a la disminución de la pobreza.

El presente documento se centra en una revisión teórica que permite hacer una aproximación al cumplimiento del ODS1Ffin de la pobreza, a partir de la revisión conceptual de la pobreza, gestión empresarial, responsabilidad social empresarial, innovación, negocios inclusivos y cadena de valor.

Resulta pertinente vincular la base de la pirámide a las cadenas de valor ya que se ofertan como una ventaja competitiva, en ese sentido, se analiza cómo contribuir a la disminución de la pobreza trabajando con la base de la pirámide donde el Estado, empresas privadas y la sociedad en conjunto sean incluyentes y orienten esfuerzos para combatirla desde la gestión empresarial. Las cadenas de valor facilitan que las empresas sean más incluyentes y sostenibles de forma que pueden contribuir a mejorar las condiciones de vida de la sociedad.

Este análisis se contrasta con los avances que en esta materia ha alcanzado América Latina, de manera que se pueda identificar si las cadenas de valor y la responsabilidad social han logrado contribuir con la disminución de la pobreza, esto con el propósito de avanzar en su estudio y se sugiere una fase práctica donde se puedan validar

Background: Cervical cancer is ranked as the most frequent cancer in women in India. Conventional papanicolaou smear has been the mainstay of cervical cancer screening since the 1960s. As an alternative liquid-based cytology (LBC) was introduced in the mid-1990s, which are found to increase cytologic detection of squamous intraepithelial lesions and a reduction in the number of unsatisfactory pap tests.Present study aims at comparison of liquid-based cytology with conventional cytology in detecting uterine cervical intraepithelial lesions.Methods: The present study was conducted in the department of pathology in collaboration with the department of obstetrics and gynecology, Pt. B.D. Sharma PGIMS Rohtak including 100 non-pregnant female patients coming in the outpatient department of obstetrics and gynecology. Both liquid based and conventional pap smears were examined under the microscope and reported according to the 2001 Bethesda system. Cell blocks were prepared sin all the cases from the residual material of LBC.Results: Median age was 42 years. More inadequate smears were reported on CS (17%) as compared to LBC (11%). In both, maximum number of cases reported were inflammatory. Equal number of cases were reported as SCC (n=4) in both.Conclusions: Liquid based cytology has been developed to address the sampling problems of conventional Pap smear. But because of the increased cost of LBC in terms of capital investment, operation and disposables, developing countries should carefully consider the potential benefits and drawbacks of LBC before adopting this new technology.

Published: August 2021

: Colorectal cancer, is third most frequently encountered malignancy worldwide. Histological grade, stage, and proliferative index act as vital prognostic markers, playing a decisive role in patient care and prognosis. While histopathological examination can determine grade and stage, Ki67 protein expression by immunohistochemistry represents the proliferative capacity of the malignant cell population. : This Study was conducted to immunohistochemically analyze expression of Ki67 protein and its change with respect to different grades and stage of colorectal adenocarcinoma. : A total of 66 histologically diagnosed cases of colorectal carcinoma underwent histopathological examination followed by immunohistochemistry for Ki67 protein. : A statistically significant (p=0.04) correlation was obtained between Ki67 labelling index and histopathological grade, with higher values of Ki67 labelling index in poorly differentiated carcinomas (43.2±1.7). The Ki67 labelling index value was lowest in stage IV disease (11.4±2.4) with metastatic burden, with higher values in lower stage diseases, however this correlation was not found to be significant statistically (p=0.07). : The rate of cell division and proliferation measured by Ki-67 antibody is related to histological grade of the malignancy, demonstrating higher mitotic activity with loss of differentiation and anaplasia. Stage IV disease have lower mitotic activity, thus may be less amenable to cytostatic chemotherapy drugs, and require multimodality treatment with addition of radiotherapy and other drug regimes.

Imaging studies have shown enlargement of pancreatic parts in children diagnosed with acute pancreatitis. The purpose here is to develop imaging based diagnostic evaluation criterion for acute pancreatitis in children. This study included 62 children of acute pancreatitis in the age range of 0.33 to 13 years, as reported in a single hospital center (1994-2019). A study was planned including 1116 normal healthy children in the age range of 0.16 to 18 years for pancreatic evaluation during 2016-17. Ultrasonography based measurement of three pancreatic parts were obtained for each individual in disease and normal groups. Age-adjusted receiver operating characteristics curve analysis was performed on each pancreatic part independently to derive respective cut-offs using a training set. These cut-offs were further referred to dichotomize the measurement data for each individual and was subjected to multiple logistic regression with presence/absence of acute pancreatitis as dependent variable. A probability score and accordingly the cut-off were obtained indicating a collective impression of enlargement of pancreas in disease condition independently for males and females. On test data, the accuracy of age-adjusted cut-offs for three parts was near 80% for males, while it ranged between 81-85% for females. ROC analysis of probability score resulted into threshold value of 0.024 for males and 0.044 for females, with sensitivity of 94.11% and 90.91% respectively. The classification accuracy of score derived for males and females was nearly same (83%). The extent of enlargement of pancreas in acute pancreatitis in children can be determined using the MLR method along with hypoechogenicity.

Published: August 2021

Pilonidal sinus is a blind ending track containing hair follicles within it and is primarily a disease involving sacrococcygeal region. The exact etiology of this disease process is unknown and is still controversial. There are various treatment methods for pilonidal sinus and the preferred method is Limberg flap reconstruction surgery due to its less complications and less recurrence. Our study was a prospective study including 28 patients who were admitted for pilonidal sinus and operated by Limberg flap reconstruction surgery at Veer Surendra Sai Institute of Medical Sciences And Research from January 2018 to June 2020. Our study included 28 patients, and the female to male ratio is 1:13. Duration of symptoms had a range from 1-4 months and the mean age of the study population was 28.5 year. Patients underwent Limberg flap reconstruction surgery and 89.28% followed a normal course after surgery , 7.14% developed seroma and 3.57% developed surgical site infection in their post-operative period. Limberg flap reconstruction surgery is the most preferred method of treatment for pilonidal sinus because of its low infection and recurrence rates, better aesthetic results after surgery and short duration of hospital stay.

Congestive heart failure (CHF) occurs when the heart doesn’t pump blood to meet the oxygen demand of the various organs. Usually congenital heart disease (CHD) like VSD, PDA, CoA, TGA physiology, ECD, Ebstein anomaly present with CHF before U5 age. In India most common cause of CHF from 5 to 15 yrs. age is due to Rheumatic Fever / RHD. We also get cases like pericardial effusion, constrictive pericarditis, DCM, AR in rheumatic disease, iron overload causing myocardial failure in Thalassemia and anemia presenting as CHF as in more than 5-year children. CHF cases contribute to about 10% of mortality in children.We conducted a Hospital based descriptive and cross-sectional study from November 2018 to October 2020 at Pediatric department of M.K.C.G Medical College Hospital, Berhampur. All pediatric patients with signs and symptoms of CHF as per clinical diagnosis in the age group of 1 month to 14 year were included in our study. The study population was 136. Out of the total cardiac cases, 57% were CHD, 43% were acquired. Among the total 105 cardiac cases of CHF, CHD were 60(57.2%). Out of the total CHD, acyanotic heart diseases were 46.7% and acquired heart diseases constituted 42.8%. Out of total 136 cases 87(63.2%) were discharged, 23(17.6%) died, 19 cases (14%) were referred to higher centre. After data collection detail analysis was made by SPSS software. An initiative regarding addressing the problematic Congestive heart failure along with its clinical management will definitely help the future generation and researchers.

Published: August 2021

State Agricultural Universities (SAUs), in India, have adopted the U.S. land-grant model to meet its goals. They are autonomous organisations with state-wide responsibility for agricultural education, research and extension education. Through teaching, research and extension activities the 64 SAUs across 28 states of India are significantly contributing to agricultural production and productivity of their respective states directly and therefore to the rural development. SAUs rural development strategies include technologies and innovations, extension and human resource development. Regional Agricultural Research Stations in various agro-climatic zones have strengthened research-extension-farmer (REF) linkages. KVKs under administrative control of SAUs serve as farm science centres of their respective districts. In this paper, the rural development approaches of Acharya N.G. Ranga Agricultural University, Guntur Andhra Pradesh is detailed. Furthermore, strategic planning by the SAUs to increase their effectiveness for direct rural development should be sustained.

Oil Saturation Index in Hydrophobic Carbonate Reservoir: Evaluation Aspects
Authors: Khanbikova Regina , Bazarevskaya Venera , Sotnikov Oleg , Bachkov Albert 
Published: August 2021

Abstract
Hydrocarbon reserves in carbonate reservoirs account for 38% - 60% of total world reserves, according to different estimates. In Tatarstan, carbonate reservoirs are found, mostly, in the eastern slope of the Melekess Depression and the South-Tatarian Arch. The carbonate reservoirs are confined to the Middle and Lower Carboniferous sediments, the Upper Devonian (including the domanik sediments), and the Upper Permian (the Kazanian heavy oil accumulations). Considering an extensive geographic and stratigraphic range and differing tectonic and sedimentation environments, the carbonate rocks are characterized by a variety of reservoir properties.
In contrast to terrigenous rocks, the carbonate void space is complicated by secondary processes that took place much later than the sedimentogenesis-lithogenesis stage. Numerous fissures, caves, sutures, and stylolites form the void space of the reservoir rock matrix containing commercial hydrocarbon reserves. In addition to fracturing and vugginess contributing to increase of void space of carbonate rocks, the secondary processes include sulphatisation and secondary dolomitization (in limestones), adding to deterioration of reservoir properties. The secondary processes impede understanding and evaluation of reservoir properties and saturation potential, in particular, determination of the oil and gas saturation factors (Dyakonova T.F. et al, 2019, Akhmetov R.T. et al, 2017)/
In the western slope of the South-Tatarian Arch, carbonate reservoirs are confined to the Middle and Lower Carboniferous sediments. Numerous RCAL and SCAL investigations provided valuable insight into these targets. In this paper, we used data from the laboratory experiments and studies of core and oil samples from the six neighbor fields on the western slope of the South-Tatarian Arch. Because of common sedimentological and tectonic sedimentation environments and lithological similarity of rocks within the stratigraphic referencing, the six fields under analysis were considered as analogous, and the results of the laboratory studies of the samples were reviewed collectively.

Abstract
A new virus, named Mutum virus, of the Family Tymoviridae was isolated from mosquitoes (Mansonia spp.). This virus was isolated in clone C6/36 cells. After complete sequencing, it presented a genome with 6,494 nt. The isolated virus is phylogenetically more related to two viruses isolated from Culex spp. mosquitoes: Ek Balam virus, isolated from Mexico, and Culex-originated Tymoviridae-like virus, isolated from China. Owing to the similarity of the protein coding domains, genomic organization, and phylogenetic analysis, we suggest that this virus belongs to a new genus, family Tymoviridae
Research on Anomalous Behavior Detection and Dangerousness Assessment among Civil Aviation Passengers at Checkpoints
Authors: Shen Haibin , Zhang yan 
Published: August 2021

Abstract
Traditional civil aviation security check measures are focused on baggage rather than passengers. The goal of this study is to enhance the level and effectiveness of security measures. We propose an anomalous behavior detection technique for civil aviation passengers and a passenger risk-assessment method based on a neural network method. A large number of real cases were analyzed and summarized to extract indicators of anomalous behavior of civil aviation passengers, and an index system was developed to detect anomalous behavior of passengers at checkpoints. A neural network method was used to evaluate the passengers and classify the risk level to detect potentially dangerous personnel, monitor people, and create an emergency warning system. The synthetic minority oversampling technique (SMOTE), the conjugate gradient method, and a multilayer perceptron neural network were used to classify the risk level of passengers at checkpoints. The results demonstrated that the proposed index system and evaluation method were well suited to deal with the ambiguity and uncertainty in the recognition process. The anomalous behavior of civil aviation passengers at checkpoints and the associated threat level were accurately identified.

Abstract
Cue-induced drug craving and disinhibition are two essential components of continued drug use and relapse in substance use disorders. While these two phenomena develop and interact across time, the temporal dynamics of their underlying neural activity and their interaction remain under-investigated. To explore these dynamics, an analysis of time-varying activation was applied to fMRI data from 62 men with methamphetamine use disorder in their first weeks of recovery in abstinence-based treatment program. Using a mixed block-event, factorial cue-reactivity/Go-NoGo task, and a sliding window across the task duration, dynamically-activated regions were identified in linear mixed effects models (LMEs). Habituation to drug cues across time was observed in the superior temporal gyri, amygdalae, left hippocampus, and right precuneus, while response-inhibition was associated with the sensitization of temporally-dynamic activations across many regions of the inhibitory frontoparietal network. Cue-reactivity and response-inhibition dynamically interact in the parahippocampal gyri and right precuneus (corrected p-value < 0.001) regions, which show a declining cue-reactivity contrast and an increasing response-inhibition contrast. Overall, the declining craving-related activations (habituation) and increasing inhibition-associated activations (sensitization) along the task duration suggest the gradual recruitment of response-inhibition process and the concurrent habituation to drug cues in areas with significant dynamic interaction. This exploratory study demonstrates the time-variance of the neural activations undergirding cue-reactivity, response-inhibition, and their interaction, and suggests potentials to assess this dynamic interaction. This preliminary evidence provides justifications for new avenues in biomarker development and interventions using cue exposure paradigms, which could promote habituation to drug cues and sensitization in inhibitory control regions.
