Diagnostic Utility and Accuracy of Scrape Cytology in Evaluation of Neoplastic Lesions
Authors: Sharma Tanya , Singhal Sheetal , Kapoor Neelkamal 
Published: November 2021

Background:
Frozen section, intraoperative fine needle aspiration cytology (FNAC) and imprint cytology have been used traditionally by the surgical pathology laboratories for rapid intraoperative diagnosis of tumors. Scrape cytology is a modification of imprint cytology that involves lightly scraping or brushing cells from freshly cut surface of the surgically removed tumor specimens. The present study was carried out to evaluate the utility of scrape cytology in diagnostic evaluation of tumors.

Material and Methods:
A prospective study was carried out at a tertiary care teaching hospital in Central India. A total of 50 consecutively received specimens in the Department of Pathology and Laboratory Medicine with clinical or radiological suspicion of neoplasia were included in the study. Scrape smears were prepared from freshly cut surface of tumor specimens received unfixed or in 10% formalin.

Results:
Overall, the scrape cytology diagnosis was concordant with final histopathological diagnosis in 48 out of 50 cases with a diagnostic accuracy of 96%. The sensitivity was 90.9% (CI-58.72% to 99.77%) and specificity was 97.4%(CI-86.52% to 99.94%). Positive predictive value and negative predictive value were 90.91% and 97.44%, respectively.

Conclusion:
Scrape cytology is a cost-effective and reasonably accurate cytodiagnostic technique for rapid tumor diagnosis. Scrape cytology can be a useful supplementary tool to frozen section, and may be applied for rapid diagnosis where frozen section technique is not available. The material and knowledge obtained from scrape cytology of routinely received histopathological specimens can be utilized as a teaching material and may help unveil diagnostic cytopathological features of infrequent cytologically encountered lesions.

Objective:
This study aimed to describe the cytological features of neuroendocrine breast tumors and to show the effect of the extent of neuroendocrine differentiation on cytological features.

Methods:
Breast tumor excision materials showing immunostaining with neuroendocrine markers (Synaptophysin or Chromogranin A) were determined and divided into two groups: cases with focal (10%–50% of tumor cells) staining and cases with diffuse (>50% of tumor cells) staining. A group of cases without neuroendocrine features/staining was used as control group. Fine needle aspiration biopsy specimens of the tumor mass or metastatic lymph nodes were examined and compared.

Results:
Twenty cases with neuroendocrine differentiation were included. Eleven cases were in the diffuse group, nine cases were in the focal group. Clean background, high cellularity, loosely cohesive cell groups with monotonous appearance, and naked nuclei were more common in the diffuse group. On the contrary, tight cohesive cell groups, the proportion of large cells, nuclear pleomorphism, and nucleolar prominence were higher in the group with focal staining. Plasmocytoid appearance, isolated cell groups, and binucleation were in similar distribution in both groups. Although round-oval nuclei were dominant in both groups, round nuclei were observed to be slightly more in the diffuse group. Only two cases in diffuse group showed cytoplasmic granularity and one case in focal group showed necrosis and mitosis. In the control group, tight cohesive groups, large cell size, pleomorphism, prominent nucleoli, and coarse chromatin were more commonly encountered.

Conclusions:
Clean background, hypercellularity, loss of cohesion, naked nuclei, monotonous cells with round nucleus, and granular cytoplasm were more prominent in cases showing diffuse staining with neuroendocrine markers. Suspecting neuroendocrine differentiation in tumors that show focal staining with neuroendocrine markers can be challenging in cytological preparations.

Informal land disputes settlement mechanisms epitomize a classic example of valuable and useful indigenous knowledge, which Africans have acquired for ages but is not being recognized and sometimes not fully utilized in contemporary African societies. The study aimed to assess the role of informal land dispute settlement mechanisms on family land ownership in Tanzania: A case of Mbeya district. The specific objectives of the study were to identify nature and causes of informal land dispute settlement mechanisms on family land ownership in Mbeya district and to examine the effectiveness of informal land dispute settlement mechanisms on family land ownership in Mbeya district. The study adopted case study research design, target population of the study was 446 respondents, and sample size of the study was 128 respondents. This study employed both qualitative and quantitative research approach data collection tools used was questionnaires, interview and focus group discussion. The study findings indicated that causes of disputes on family land ownership and effectiveness of informal dispute settlement mechanism significantly lead to family land ownership conflicts in Mbeya district as well as in Tanzania. The study concluded that informal land dispute settlement mechanisms help people within the community to attain land ownership through chiefs and community elders because this mechanism can strengthen solidarity, ethnics discipline in the community and recommended that the government should formulate policy and law governing informal land dispute settlement mechanisms on family land ownership to be accommodated in the local system to facilitate quickly land matters rather than depending on western system.

Published: November 2021

Topics related to the modeling of turbulent flow feature significant relevance in several areas, especially in engineering, since the vast majority of flows present in the design of devices and systems are characterized to be turbulent. A vastly applied tool for the analysis of such flows is the use of numerical simulations based on turbulence models. Thus, this work aims to evaluate the performance of several turbulence models when applied to classic problems of fluid mechanics and heat transfer, already extensively validated by empirical procedures. The OpenFOAM open source software was used, being highly suitable for obtaining numerical solutions to problems of fluid mechanics involving complex geometries. The problems for the evaluation of turbulence models selected were: two-dimensional cavity, Pitz-Daily, air flow over an airfoil, air flow over the Ahmed blunt body and the problem of natural convection between parallel plates. The solution to such problems was achieved by utilizing several Reynolds Averaged Equations (RANS) turbulence models, namely: k-ε, k-ω, Lam-Bremhorst k-ε, k-ω SST, Lien-Leschziner k-ε, Spalart-Allmaras, Launder-Sharma k-ε, renormalization group (RNG) k-ε. The results obtained were compared to those found in the literature which were empirically obtained, thus allowing the assessment of the strengths and weaknesses of the turbulence modeling applied in each problem.

Published: November 2021

Knowledge about coastal and small island ecosystems is increasing for the monitoring of marine resources based on remote sensing. Remote sensing data provides up-to-date information with various resolutions when detecting changes in ecosystems. Studies have defined a shift in marine resources but were limited only to pixel or object classification in changes of seagrass area. In the present study, two classification method analysis approaches were compared to obtain optimum results in detecting changes in seagrass extent. It aimed to determine the dynamics of a seagrass ecosystem by comparing two classification methods in the waters of Gusung Island and Pajenekang, South Sulawesi, these methods being pixel-based and object-based classification methods. This research used SPOT-7 satellite imagery with 6 m2 of spatial resolution. Accuracy assessment using the confusion matrix showed optimum accuracy in object-based classification with an accuracy value of 87 %. Meanwhile, pixel-based classification showed an accuracy value of 78 % around Gusung Island. Pajenekang Island had accuracy values of 69 % with object-based classification and 65 % with pixel-based classification. A comparison of both classification methods revealed statistically high accuracy in mapping the benthic habitats of seagrass ecosystems. The results of the classifications showed a decline in the area of seagrass populations around Gusung Island from 2016 - 2018 and around Pajenekang Island from 2013 - 2017, with a change rate of 11.8 % around the island of Gusung and 7.6 % around the island of Pajenekang. This can explain the reason for the temporal method of object-based research classification having the best potential to process data changes in areas of seagrass in South Sulawesi waters and remote sensing information for the mapping of coastal area ecosystems.
HIGHLIGHTS

Information on coastal ecosystems globally with remote sensing data is currently very easy to access, but information related to ecosystem management and seagrass ecology in certain areas is still limited
Analysis of seagrass benthic changes in shallow water requires data processing methods with high accuracy
The OBIA (Object Based Image Analysis) method is one of the analytical methods that can provide optimal results in observing changes in seagrass ecosystems in the waters of South Sulawesi, Indonesia

Published: November 2021

Researchers have collected Twitter data to study a wide range of topics, one of which is a natural disaster. A social network sensor was developed in existing research to filter natural disaster information from direct eyewitnesses, none eyewitnesses, and non-natural disaster information. It can be used as a tool for early warning or monitoring when natural disasters occur. The main component of the social network sensor is the text tweet classification. Similar to text classification research in general, the challenge is the feature extraction method to convert Twitter text into structured data. The strategy commonly used is vector space representation. However, it has the potential to produce high dimension data. This research focuses on the feature extraction method to resolve high dimension data issues. We propose a hybrid approach of word2vec-based and lexicon-based feature extraction to produce new features. The Experiment result shows that the proposed method has fewer features and improves classification performance with an average AUC value of 0.84, and the number of features is 150. The value is obtained by using only the word2vec-based method. In the end, this research shows that lexicon-based did not influence the improvement in the performance of social network sensor predictions in natural disasters.
HIGHLIGHTS

Implementation of text classification is generally only used to perform sentiment analysis, it is still rare to use it to perform text classification for use in determining direct eyewitnesses in cases of natural disasters
One of the common problems in text mining research is the extracted features from the vector space representation method generate high dimension data
A hybrid approach of word2vec-based and lexicon-based feature extraction experiment was conducted in order to find a method that can generate new features with low dimensions and also improve the classification performance

Electron impact dissociation of CO2 (a review)
Authors: Lebedev Yurii , Shakhatov Vyasheslav 
Published: November 2021

Based on a detailed analysis and generalization of the results of calculations of the energy spectrum of electrons using different models in gas discharges in pure carbon dioxide CO2 and in mixtures containing CO2 , the rate constant of CO2 dissociation by electron impact in a gas discharge of direct current at atmospheric pressure is found. It is shown that, at values of the reduced electric field from 55 Td to 100 Td, the predominant
mechanism of decomposition of the CO2 molecule is the collision of CO2 molecules with electrons. An expression is obtained for calculating the rate constant of CO2 dissociation by electron impact as a function of the reduced electric field.
Theoretical analysis of the factors, influencing composition uniformity of the cadmium zinc telluride substrates grown by THM
Authors: Senchenkov Alekxander 
Published: November 2021

The effect of the sample composition, variation of the temperature field and the feed material non-homogeneity on uniformity of the growing crystal is considered. It is shown
that optimization of the solvent composition makes it possible to minimize the jump of the ZnTe concentration at the seed/crystal boundary. The composition fluctuations at variation of the thermal field during crystal growth are smooth enough and relatively
non-significant. The feed composition distribution has, as a rule, a random character. Different harmonics of composition distribution non-uniformity in the feed material differently affect the homogeneity of the growing crystal. Longwave non-uniformities in the feed transform into the growing crystal almost completely. At the wavelength equals to a half of the solvent length or shorter, the perturbations of the growing crystal composition are relatively small. Evidently, the cause of the local composition variations, found in real crystals, is, basically, the feed composition non-uniformities

Published: November 2021

Data from 2 randomized controlled trials indicated a statistically significant benefit in progression-free survival and overall survival for patients with follicular lymphoma who received R2 as compared to patients who received rituximab plus placebo or R-CHOP.
The frequency of all types of adverse events in patients receiving R2 as compared to rituximab plus placebo or R-CHOP was comparable, but patients receiving R2 experienced more severe adverse events.
Two economic analyses concluded that R2 was cost-effective for the treatment of patients with follicular lymphoma as compared to rituximab plus placebo (UK and Dutch contexts).
Evidence identified in this review was mostly limited to that describing patients with follicular lymphoma.
Most evidence identified in this review was generated with support and/or funding from a private industry pharmaceutical manufacturer.
The Role of Mathematical Values Concept in the Internalization of Insan Kamil
Authors: 'Azizah Nilatul , Fitriya Ita 
Published: November 2021

The lack of knowledge and understanding of human beings to the values implied in mathematics that causes mathematics is considered as a lesson that is very contrary to the concept of religion, especially the field of Sufism when in fact mathematics is a means provided by Allah SWT to facilitate people to carry out the task of servitude and the task of the caliphate to the level of insan kamil. This research uses a qualitative approach. Literature review was used to obtain research data. The results of this study state that the concept of mathematical values in the internalization of insan kamil is to encourage humans to develop problem solving skills, communication skills, and reasoning skills to face every situation and problem in life. This discussion also presented that mathematics in addition to teaching to think and reason but also teach honest, humble, not arrogant, sincere, iffah, consistent and systematic attitude. This is a reflection of insan kamil.
