Educational Data Mining (EDM) is gaining great importance as a new interdisciplinary research field related to some other areas. It is directly related to data mining (DM), the latter being a fundamental part of knowledge discovery in databases (KDD). This data is growing more and more and contains hidden knowledge that could be very useful for users (both teachers and students). It is convenient to identify such knowledge in the form of models, patterns, or any other representation scheme that allows better exploitation of the system. Data mining is revealed as the tool to achieve such discovery, giving rise to EDM. In this complex context, different techniques and learning algorithms are usually used to obtain the best results. Recently educational systems are adopting artificial intelligent systems, especially in the educational context, specific areas for extracting relevant information, such as EDM, which integrates numerous techniques that support the capture, processing, and analysis of these sets of records. The main technique associated with EDM is Machine Learning, which has been used for decades in data processing in different contexts, but with the advent of Big Data, there was an intensification in the application of this technique to extract relevant information from a huge amount of data. This paper proposes the student performance prediction using CNN (Convolution Neural Network) and BPSO (Binary Particle Swarm Optimization) based feature selection method. In this study, classifiers are made for 2-class and 5-class predictions. The proposed system claims an outperforming accuracy of 96.6% with various previous research works as well as found that the majority of attributes related to school activities as compared to data on demographic and socioeconomic characteristics.

Background

Limited budgets may often constrain the ability of health care delivery systems to adopt shared decision-making (SDM) systems designed to improve clinical encounters with patients and quality of care.

Objective

This study aimed to assess the impact of an SDM system shown to improve diabetes and cardiovascular patient outcomes on factors affecting revenue generation in primary care clinics.

Methods

As part of a large multisite clinic randomized controlled trial (RCT), we explored the differences in 1 care system between clinics randomized to use an SDM intervention (n=8) versus control clinics (n=9) regarding the (1) likelihood of diagnostic coding for cardiometabolic conditions using the 10th Revision of the International Classification of Diseases (ICD-10) and (2) current procedural terminology (CPT) billing codes.

Results

At all 24,138 encounters with care gaps targeted by the SDM system, the proportion assigned high-complexity CPT codes for level of service 5 was significantly higher at the intervention clinics (6.1%) compared to that in the control clinics (2.9%), with P<.001 and adjusted odds ratio (OR) 1.64 (95% CI 1.02-2.61). This was consistently observed across the following specific care gaps: diabetes with glycated hemoglobin A1c (HbA1c)>8% (n=8463), 7.2% vs 3.4%, P<.001, and adjusted OR 1.93 (95% CI 1.01-3.67); blood pressure above goal (n=8515), 6.5% vs 3.7%, P<.001, and adjusted OR 1.42 (95% CI 0.72-2.79); suboptimal statin management (n=17,765), 5.8% vs 3%, P<.001, and adjusted OR 1.41 (95% CI 0.76-2.61); tobacco dependency (n=7449), 7.5% vs. 3.4%, P<.001, and adjusted OR 2.14 (95% CI 1.31-3.51); BMI >30 kg/m2 (n=19,838), 6.2% vs 2.9%, P<.001, and adjusted OR 1.45 (95% CI 0.75-2.8). Compared to control clinics, intervention clinics assigned ICD-10 diagnosis codes more often for observed cardiometabolic conditions with care gaps, although the difference did not reach statistical significance.

Conclusions

In this randomized study, use of a clinically effective SDM system at encounters with care gaps significantly increased the proportion of encounters assigned high-complexity (level 5) CPT codes, and it was associated with a nonsignificant increase in assigning ICD-10 codes for observed cardiometabolic conditions.

The Use of Machine Learning to Reduce Overtreatment of the Axilla in Breast Cancer: Retrospective Cohort Study
Authors: Jozsa Felix , Baker Rose , Kelly Peter , Ahmed Muneer , Douek Michael
Published: October 2022

Background

Patients with early breast cancer undergoing primary surgery, who have low axillary nodal burden, can safely forego axillary node clearance (ANC). However, routine use of axillary ultrasound (AUS) leads to 43% of patients in this group having ANC unnecessarily, following a positive AUS. The intersection of machine learning with medicine can provide innovative ways to understand specific risks within large patient data sets, but this has not yet been trialed in the arena of axillary node management in breast cancer.

Objective

The objective of this study was to assess if machine learning techniques could be used to improve preoperative identification of patients with low and high axillary metastatic burden.

Methods

A single-center retrospective analysis was performed on patients with breast cancer who had a preoperative AUS, and the specificity and sensitivity of AUS were calculated. Standard statistical methods and machine learning methods, including artificial neural network, naive Bayes, support vector machine, and random forest, were applied to the data to see if they could improve the accuracy of preoperative AUS to better discern high and low axillary burden.

Results

The study included 459 patients; 142 (31%) had a positive AUS; among this group, 88 (62%) had 2 or fewer macrometastatic nodes at ANC. Logistic regression outperformed AUS (specificity 0.950 vs 0.809). Of all the methods, the artificial neural network had the highest accuracy (0.919). Interestingly, AUS had the highest sensitivity of all methods (0.777), underlining its utility in this setting.

Conclusions

We demonstrated that machine learning improves identification of the important subgroup of patients with no palpable axillary disease, positive ultrasound, and more than 2 metastatically involved nodes. A negative ultrasound in patients with no palpable lymphadenopathy is highly indicative of low axillary burden, and it is unclear whether sentinel node biopsy adds value in this situation. Further studies with larger patient numbers focusing on specific breast cancer subgroups are required to refine these techniques in this setting.

Published: October 2022

Teachers feel their work is becoming increasingly stressful and their status is falling leading to less job satisfaction with a concomitant loss in motivation. This study sought to find out in quantitative terms, the amount of motivation that the intrinsic and extrinsic socio-economic factors make to teacher motivation. The research design employed for this research is quasi-experimental. Two thousand and ninety-eight (2,098) teachers were selected from the Upper East Region of Ghana. Both quantitative and qualitative data was collected. The results showed that intrinsic and extrinsic socio-economic factors do motivate teachers in the execution of their work. However, not a strong association exist between teacher motivation and the intrinsic and extrinsic socio-economic variables. Not much of teacher motivation depends on socio-economic factors. Per the findings of the study, the association between the degree of motivation that teachers receive from the intrinsic and extrinsic socio-economic factors, M€, and the percentage of respondents that claim they are motivated by the factors, f€, could be represented by the polynomial relation, M€ = µ3(f€)3 - µ2(f€)2 + µ1(f€) - µ0. Intrinsic and extrinsic (socio-economic) factors cannot sustain the motivation of teachers permanently, even though the lack of them will lead to demotivation of teachers.
The United Nations Human Rights Council’s 2017 Report on Financialization of Housing
Authors: Ninepence Prof. Albert Mcbell
Published: October 2022

Financialization of housing has attracted plenitude of divergent reviews and discussions on the subject matter. The termfinancialization of housing has been associated with reduced housing affordability in recent debates. Irrespective of financialization of housing cementing a springboard to augment growth of the financial and housing markets, enhanced employments and deepened international trade and relations, it has also created its own setbacks. The financialization of housing has been reviewed to trigger excessive demerits of capital gains exceptions, rent seeking and disregard to upholding and defense of human rights tenets, provisions and conventions. In support of these demerits, the United Nations Human Rights Council’s 2017 report on the financialization of housing underscore financialization of housing creating an overall negative impact. The UN reports posits that the finacializationof housing is now a means to secure and accumulate wealth. Housing is now dehumanized and sold as a commodity on global markets and hence has lost its currency as a universal human right. The copious reviews and contention on the financialization of housing warrants further inquiry into the compendious scholarship. This paper therefore examined and argued in favour of the UN standpoints though making counter perspectives on the discourse of financialization of housing.

Published: October 2022

This article considers the origins and historical evolution of agroecology and its connection with the multi and interdisciplinarity, highlighting the main theoretical concepts and their epistemological and methodological bases built by classical and postmodernist thinkers through their formulations on the themes, where, despite the diversified views, agroecology in a hegemonic way is pointed out as a science under construction that seeks alternative and sustainable models for the socioeconomic, cultural, environmental and ethical development of the farmer with respect to the environment. It also brings the discussion of agroecology and interdisciplinarity into the academy in undergraduate and graduate courses in agroecology, highlighting the importance of continuing education for teachers and students, with a view to building new approaches that recognize the importance of cultural diversity and exchanges between scientific and popular knowledge. Women are identified here as protagonists of advances in the transition from conventional to agroecological agriculture, either for their participation or for the struggles undertaken in the consolidation of this system, which, in addition to production, constitutes a way of life and work.

The Bovine Respiratory Diseases Complex (BRD) is characterized by respiratory tract infection and may be origin by viral, bacterial or through the association of both. BRD has been identified as one of the most important causes of morbidity and mortality of intensive breeding, especially in young animals, causing serious economic losses with the use of drugs for treatment of animals and significant losses of weight, directly affecting the meat production. The objective of this study was to verify the presence, through the serological and / or antigenic detection, of etiological agents that cause BRD in blood and nasal swab samples, such as Bovine Hespesvirus Type 1 (BoHV-1), Bovine Viral Diarrhea Virus, Parainfluenza Type 3 virus (BPI-3). There were evaluated 100 bulls from four properties in the municipality of Paranatinga sent for termination in a feedlot located in the municipality of Ipiranga do Norte, MT. According to the results obtained, a high prevalence of the viral agents studied was observed, mainly the BPI-3 and BoHV-1 viruses. The results indicate the circulation of agents that cause diseases of importance in beef cattle, thus requiring greater vigilance over them in feedlots.
Analogy between the Philosophical Ideas of Simone de Beauvoir and Amrita Pritam
Authors: Goel Somya
Published: October 2022

This paper focuses on the works of both of these women and aims to carry out a comparative study via a conceptual methodology of research. Both were about 4000 miles apart yet so closely linked with their philosophical ideas and stand on topics like sexuality, women and their sufferings, feminism, etc. There is a vast difference between the works of both spectacularly talented women, in terms of language, context, and writing style but still, the very essence of their work denotes similar notions. Even after decades, their works are widely read and deliberated upon by people when it comes to feminism. Having said that, it is also true that their work did not die even after so many years and it will most probably continue in the future as well, whether supported, discussed, opposed, or criticized. The paper focuses primarily on the question of the relevance of their work in the present period, and on whether the ideas of Amrita Pritam and Simone de Beauvoir remain similar throughout or did they contradict each other at some point.

Published: October 2022

Simulation is an approach used in teaching to enhance students learning especially when the concept being taught is abstract and hands on activity is not possible. However, it serves its purpose only if it is effectively implemented in the real classroom situation. Using a mixed method approach, a study on the effectiveness of simulation in teaching Geometrical Optics in class IX physics was conducted in one of the schools of Bhutan. For the quantitative approach quasi-experimental design was employed involving 70 students (35 experimental, 35 control group) and two physics teachers. Five students from experimental group and two subject teachers were interviewed. The findings of the study revealed that students taught using the simulation approach performed better than those using the conventional method. The finding also revealed that the simulation approach enriched students’ attentiveness and self-exploration in learning physics. Some of the recommendations from the study included the need to provide professional training on simulation to teachers, and make adequate ICT facilities available in the schools to support learning through simulation. The study also recommends future researchers to replicate this study in other subjects to find the effectiveness of the approach.

Published: October 2022

Abstract: Many construction projects experience schedule and expense overruns which results in poor planning, scheduling, and execution, which causes number of problems such as delays in the provision of facilities, development, a decline in construction quality, and an increase in project cost. A little thought reveals that the amount of time needed to accomplish the job is inversely related to the availability of labor. When the number of workers is raised, the project's completion time is shortened; conversely, when the number of workers is reduced, the project's completion time is lengthened. The present study deals with the manpower, planning, scheduling and resource optimization of “Construction of a Villa Project at Chaitanya Sharan, Bengaluru”, a two storied (G+2) building of 26 units whose construction is complete at Gunjur, Bengaluru, Karnataka. This study uses Microsoft Project 2013 to schedule various building activities, allocating resources, and level those resources in order to examine project management strategies. In essence, it relates to finding a solution to the project's excessive resource allocation. This project illustrates how resource levelling may be accomplished with Microsoft Project and what impact it might have on overall project duration.

Abstract: In a digital era, people prefer to use smart gadgets and it is growing to be instrumental in daily lives. The features of the smartphone are also evolving, leading to effectiveness for end users. With such an aim, an android-based contact application was developed that would benefit an organization. As an interim measure, this application is based on Jigme Namgyel Engineering College under the Royal University of Bhutan. Currently, this organization do not have a 'contact application' that can be used as a digital phonebook. Therefore, the entire faculty, staff, and students have to search for contact details through person-to-person communication leading to several inconveniences. This android base application called JNEC Contact made contact detail of the college’s staff available and accessible to staff and students without an internet connection. This application is implemented specifically for JNEC to ease the difficulties of acquiring contact information of faculty and staff. The application titled JNEC Contact has other features such as text messages and mail-to-direct correspondence. It is known to be more comfortable, efficient, and user-friendly to find a contact, unlike the phonebook. The current version of the application has limited compatibility with the android version only, but it can be developed for IOS phones in the future.

Semi-Automatic Solar Powered Grass Cutter
Authors: Pawar Abhishek , Bhalerao Anushka , Tagunde Ruturaj , Undirwade Nikita
Published: October 2022

Abstract: Due to the constant rise in fuel prices and the impact of gas emissions from burned fuel into the atmosphere, it became necessary to use the sun's plentiful solar energy as a source of electricity to operate a lawn cutter. Based on the fundamental idea of mowing, a solar-powered lawn cutter was created. Direct current (DC) motor, rechargeable battery, solar panel, stainlesssteel blade, and control switch make up the solar-powered lawn cutter's design. The DC motor, which is directly connected to the shaft of the DC motor and provides the necessary torque to drive the stainless steel blade, is used to mow the lawn. The switch on the board, which shuts the circuit and permits electricity to pass to the motor, which in turn drives the blade used for mowing, is used to operate the solar-powered lawn cutter. The system will use some automation for obstacle identification and direction. A solar panel will be fixed to the top of the robot and serve as the system's power source in addition to a battery. Nobody like moving the lawn cutters when they are driven by a normal motor since it is a hassle. Elderly or younger people may find it difficult to cut the grass since a lawn cutter moving with an engine produces both local air pollution from engine combustion and noise pollution owing to the noisy engine. A motor-powered engine also needs routine maintenance, including changing the oil. Despite being ecologically beneficial, electrified solar grass may still be a pain. Electric grass cutters, like motor-powered ones, are dangerous and difficult for everyone to use. Additionally, if the electric lawn cutter is tethered, cutting might be difficult and dangerous. The prototype will also use solar panels to charge from the sun.
Interaction between a barrette and multilayered surrounding and underlying soils, taking into account their elastic and elastic-viscoplastic properties
Authors: Ter-Martirosyan Zaven G. , Ter-Martirosyan Armen Z. , Dam Hung Huu
Published: October 2022

Introduction. Upon interaction between a single barrette with underlying and loose surrounding soils the settlement of the barrette can occur for a long period of time. Therefore, the prediction of barrette settlement in time is significantly essential for building, foundation analysis and design under such geological conditions. As a result, it is vitally necessary to consider rheological processes of soils the cause of the change of barrette settlement in time. In order to clarify the abovementioned problem the setting and solutions to the problem of the interaction between a single barrette and elastic-viscoplastic surrounding and underlying soil are presented. The result indicates that the viscocity of surrounding soils greatly affects time-dependent settlement curves of a vertically loaded barrettle.

Materials and methods. The problem is considered in a linear formulation. The solution is acquired in analytical method. To figure out the changing in time process of barrette settlement, constant and variable coefficients of viscosity of soils are applied.

Results. The expressions are obtained to determine barrette settlement, friction forces on side surfaces of the barrette and reaction forces under the barrette heel. The relationship between the reaction forces under barrette toe; barrette settlement and the time are derived in regard to elastic-viscoplasticity of multilayered surrounding soil. Acquired results are presented by graphs in the article. The graphs demonstrating abovementioned relationships are provied according to various values of constant and variable coefficients of viscosity of soils.

Conclusions. The acquired solution can be applied to determine vertical displacement of a barrette when interacting with an elastic as well as elastic-viscoplastic heterogeneous soil mass. Coefficients of viscosity of surrounding soil have a significant effect on the rate of barrette settlement and stress under the barette heel. Taking into account the increase in the coefficients of soil viscosity over time affects greatly the values of long-term settlement of the barrette, as well as pressure under the barrette toe. As a result, it is possible to predict the values of stabilized settlement as well as long-term bearing capacity of a barrette interacting with an elastic-viscoplastic heterogeneous soil mass.
Estimating Poisson's Ratio and Young's Modulus of the Outer Fruit Shell of Corn Grain
Authors: Pastukhov A. G. , Vol'vak S. F.
Published: October 2022

The paper highlights the need of reducing damage caused to corn grain during cobs threshing. The damage to the grain fruit shell can be eliminated by introducing limiting conditions and ensuring optimal parameters for the threshing and separating device operation. It has been confi rmed that the patterns of corn cobs threshing can be adequately described by applying the Hertzian elastic contact theory. (Research purpose) To obtain the Poisson's ratio and Young's modulus of the fruit shell of corn grain, whose surface is in direct contact with the working bodies of the threshing device. (Materials and methods) One-factor-ata- time experiments were conducted with the subsequent statistical processing of the data array. Poisson's ratio was experimentally studied for the fruit shell of dent corn and so was Young's modulus for the grain of fl int corn, dent corn, sugar corn and popcorn. (Results and discussion) Research methods and experimental equipment have been developed to determine the Poisson's ratio and Young's modulus of the fruit shell of corn grain. It was established that with a confi dence probability of 0.95, the average Poisson's ratio value of the fruit shell of the dent corn grain equals 0.356. Young's modulus was obtained by the following corn varieties: fl int corn – 98-125 megapascals, dent corn – 78-127 megapascals, sugar corn – 97-124 megapascals, popcorn – 127-169 megapascals. It was found out that the maximum permissible speed mode of threshing can be provided if the speed of contact interaction between the grain and the threshing device pin does not exceed 1.6 meters per second. (Conclusion). It was proved that for a more comprehensive application of the Hertzian elastic contact theory when modeling the processes of threshing corn cobs, it is necessary to know the Poisson's ratio and Young's modulus for the outer fruit shell of grain. The obtained numerical values of these mechanical and technological characteristics are recommended to be used in modeling the deformation processes that regulate the threshing speed regimes.

Authors: Belyakov M. V. , Nikitin E. A. , Efremenkov I. Yu.
Published: October 2022

The spectral evaluation systems for controlling the feed mixtures homogeneity were analyzed. (Research purpose) To study the optical luminescent properties of the feed mixtures main components in the ultraviolet and visible range and develop a method for their photoluminescent quality control. (Materials and methods) Two groups of feed mixture components were studied: granular compound feed and corn silage. The spectral characteristics were measured by Fluorat-02-Panorama spectrofluorimeter. The synchronous scanning helped to identify the excitation spectra and, on their basis, the photoluminescence spectra were determined according to a previously tested technique. (Results and discussion) The components excitation spectra revealed the main maxima of 362 nanometers and 424 nanometers. All the photoluminescence characteristics proved to be single-modal, for each excitation wavelength, the measured curves are qualitatively similar, but differ quantitatively: for example, the difference in the compound feed and light silage flows is 2.4 times at a length of 232 nanometers, 2.8 times at 424 nanometers and 3.8 times at 362 nanometers. It is advisable to use 362-nanometer wavelength radiation to excite the experimental sample of the feed mixture, and to record photoluminescence within the range of 390-540 nanometers. The method of express quality control of mixing includes the following stages: initial calibration by the compound feed luminescence, sample preparation, mixture luminescence excitation, the luminescence flux registration, photo signal amplifiation and processing according to diagnostic algorithms, followed by either feed distribution or sequel mixing with repeated express control. (Conclusions) The proposed method for assessing the quality of mixing the feed mixture components can be implemented using a compact spectral device. It was found that the use of the proposed method in the technological process of preparing the feed mixture will reduce the energy costs.
The Interface of Mad Studies and Indigenous Ways of Knowing: Innovation, Co-Creation, and Decolonization
Authors: Dwornik Ania
Published: October 2022

This paper explores the interface between Mad Studies and Indigenous ways of knowing, and argues that the dialogical expanse that exists between these two fields could be a site for innovation, co-creation, and decolonization. Mad Studies is a radical approach to studying the ways we organize and respond to mental health experiences. The field questions and unsettles biomedical understandings of mental illness, and frames psychiatric experiences as diverse forms of human emotional or spiritual expression. Indigenous perspectives on disability describe mental health using a holistic, wellness-based lens, with many scholars highlighting the link to colonial violence and oppression. The interface of Mad Studies and Indigenous ways of knowing could provide a unique platform for gaining a broader understanding of Indigenous mental health while resisting Western, psy explanations of emotional distress. Different interpretations and understandings can be discussed and debated, and through ethical spaces (Ermine, 2007) new understandings or ideas may emerge. These, in turn, may help decolonize some of the dominant biomedical biases that underpin many contemporary psychiatric treatment approaches.Social workers have a particularly important role to play in these conversations. Our professional commitment to anti-oppression and social justice implores us to take an active role in these debates. Through our workplaces we can problematize dominant discourses from within dominant systems, and make our contribution to decolonization.

The result showed that students have different mathematical problem-solving abilities from each indicator, namely 1) identifying the adequacy of data for problem-solving, 2) making mathematical models from everyday situations or problems, 3) selecting and implementing strategies to solve math and math problems outside of using virtual reality games through open-ended based.
Human resource management practices and organisational performance: Evidence from small and medium-sized enterprises in Australia
Authors: Mamun Mehadi
Published: October 2022

Small and medium-sized enterprises (SMEs) are the drivers of economic activities in Australia. The present study provides empirical evidence on the connexion between the four key dimensions of human resource management (HRM) practices and organisational performance, in response to the call by earlier researchers that the influence of specific HRM practices on organisational performance needs to be further investigated across different countries and organisational contexts. A survey among SMEs in the South-Western region of Sydney in Australia was conducted and self-reported measures were applied to attain data on HRM practice aspects and businesses’ performance. Regression analyses were employed to assess the proposed relationships, and it was found that all dimensions except training and development exhibited positive relationships to organisational performance, as hypothesised.

Published: October 2022

Objective: To study the incidence of sinonasal mucormycosis in active
and post COVID-19 patients in a district-level hospital in India. Study
Design: A prospective, interventional cohort study conducted from April
2021 to January 2022. Setting: A district-level/secondary level hospital
in North India. Methods: Inclusion Criteria: All COVID-19 positive
patients with diabetes mellitus as co-morbidity and with at least one of
the following:received steroid therapy and/or on high flow oxygen
therapy and/or had prolonged hospital stay (>7 days).
Exclusion Criteria: Patients already immunocompromised/having
malignancy/organ transplant recipients. Clinical workup: History,
examination, imaging (CECT/MRI nose and paranasal sinuses if indicated),
diagnostic nasal endoscopy + Nasal scrapings for KOH mount to detect
fungal elements. Results: Fourteen out of 250 patients tested positive
for Mucormycosis (incidence 5.6%). Out of these 13 were symptomatic and
only one patient was asymptomatic and detected on screening. No
significant difference was found in mucormycosis vs. non-mucormycosis
group with respect to HbA1c status, vaccination status or steroid +
oxygen treatment (p>0.05 in all scenarios). Patients were
treated with intravenous Liposomal Amphotericin B and surgical
debridement when indicated. Two succumbed to disease (survival 85.7%).
A clinical screening protocol was thus developed which can be used as an
effective tool even at far-flung and remote healthcare facilities for
diagnosis and timely referral of patients. Conclusion: Mucormycosis is a
potentially lethal disease which needs rapid diagnosis and timely action
to decrease morbidity and mortality.

Studies have shown that fluvoxamine can be useful in preventing the
spread of Covid-19 disease (in the early stages of the disease) by
strengthening the body’s immune system. For this purpose, in this work,
the structural and electronic properties of fluvoxamine drug were
investigated using quantum theory of atom in molecule (QTAIM) and
Density-functional theory (DFT) at B3LYP-DFT/6-311G+ (at presence of
water as solvent and the CPCM model) computational level. Also, in order
to improve the electronic/pharmaceutical properties, the effect of
electron donor/acceptor groups of NO2 and NH2 on fluvoxamine was
studied. According to the results, electronic properties changed
significantly in the presence of the NO2 group. So that (in the presence
of NO2) cohesive energy, energy gap, dipole moment, adsorption energy,
antioxidant properties, and recovery time improved by 20%, 70%, 84%,
48%, 48%, and 46% respectively. Although the electronic properties
were improved in the presence of the NH2 group, the effect of the NO2
functional group was more noticeable. Therefore, it is expected that the
presence of the NO2 electron-acceptor electron group will improve its
medicinal function by changing the electronic properties of the drug
fluvoxamine.

Analyzing the dynamics of landscape connectivity is of great
significance for biodiversity conservation, but the description of
multiple ecological processes and the depth of coupling requires to be
strengthen. Taking the grassland of Poyang Lake as a case, based on the
integrated perspective of habitat and biology, comprehensively
considering the ecological process of water level change and species
diffusion, this study firstly analyzed the changes of landscape
connectivity of grassland with different water levels and diffusion
distances by using the graph-based connectivity indices. then, landscape
pattern indices were applied to analyze the dynamics of landscape
pattern of grassland and further study the effects of landscape pattern
on connectivity. The results showed as follows: (1) From the perspective
of habitat, grassland connectivity showed a sharp decrease with the
increase of water level. From the perspective of ecology, the species
diffusion distance had an absolutely positive impact on landscape
connectivity. With the increase of diffusion distance, grassland
connectivity increased significantly. (2) The dynamics of landscape
pattern of grassland showed that with the increase of water level, the
patch area shrank, the patch shape tended to be simple, the patch
density decreased and the patch fragmentation aggravated. (3) The
correlation results between landscape pattern and connectivity indicated
that F had a significant positive relationship with PD, ED, PC had a
strong significant positive relationship with LPI, COHESION, and NC had
a negative relationship with LPI, ED, COHESION. This study provides
theoretical guidance for the conservation and management of grassland in
Poyang Lake.
Handling and preservation of buffy coat isolated T cells for homologous dendritic cell co-cultures
Authors: Alobaid Meshal
Published: October 2022

The use of T cells is increasing both in healthcare and in research yet
the preservation methodologies for longer periods of times are yet to be
optimized. In order to overcome these issues, we have optimized a
protocol in sample handling and preservation of T cells in order to
perform a successful donor homologous co-culture with DCs and preserve
these cells for subsequent testing. This method will help in saving time
and effort as well as the ease of use for experiments requiring use of T
cells in mono or co-cultures. Handling and preservation of T cells using
our methodology showed stability and viability of these cells in
co-cultures. Data showed viability of >93% before and
after liquid nitrogen preservation. Moreover, preserved cells had no
unspecific activation which can be seen in unchanged expression of the T
cell activation marker CD25. T cell proliferation profile showed that
preserved T cells used in DC-T cell co-cultures (LPS stimulated DCs) had
the ability to interact and proliferate indicating potency of these
cells. This provides evidence of the efficiency of our handling and
preservation methodology in maintaining cell viability and stability.
Preserving donor T cells would facilitate reuse of these cells in donor
homologous co-cultures reducing inconvenience of multiple donations of
fresh blood and provides accessibility of the same population of T cells
for experiments that requires repetition, commercial availability of the
cells or for preservation of cells for clinical therapies such as
chimeric antigen receptor T cells.
Rate of change of J-integral in creep-fatigue condition
Authors: Tiwari Abhishek
Published: October 2022

The operational conditions in next generation power plants and other
high temperature applications such as turbine blades in jet engines
demand the component to perform under extreme conditions where metallic
materials show time dependent deformation under cyclic loading
conditions. Under creep-fatigue loading condition, the crack tip is
exposed to both time dependent and independent plastic deformation.
Conventional crack characterizing parameters such as (C t ) , avg has
shown good correlation with dominant damage based crack velocity, (d
a/d t ) avg . However, the true definition or prediction of crack
driving forces under such scenario are vague due to limited theoretical
validity of the conventional crack tip characterizing parameters, such
as J or C . In this work, the concept of
configurational forces are applied for the first time to understand the
creep-fatigue crack growth behaviour. The crack growth is simulated
using node-release technique and the configurational forces are
calculated using post processing the finite element results for
calculation of dJ/dt.

Published: October 2022

Background: Surgical management of coexisting cardiac disease
and extra-cranial carotid artery disease is a controversial area of
debate. Thus, in this challenging scenario, risk stratification may play
a key role in surgical decision making. Aim: To report the
results of single stage coronary/valve surgery (CVS) and carotid
endarterectomy (CEA), and to identify predictive factors associated with
30-day mortality. Methods: This was a multicenter,
retrospective study of prospectively maintained data from three academic
tertiary referral hospitals. For this study, only patients treated with
single stage CVS, meaning coronary artery bypass surgery or valve
surgery, and CEA between March 1, 2000 and March 30
2020, were included. Primary outcome measure of interest was 30-day
mortality. Secondary outcomes were neurologic events rate, and a
composite endpoint of postoperative stroke/death rate. Results:
During the study period, there were 386 patients who underwent the
following procedures: CEA with isolated coronary-artery bypass graft in
243 (63%) cases, with isolated valve surgery in 40 (10.4%), and
combination of coronary artery bypass grafting and valve surgery in 103
(26.7%). Postoperative neurologic event rate was 2.6% (n = 10) which
includes 5 (1.3%) TIAs and 5 (1.3%) strokes (major n = 3, minor n =
2). The 30-day mortality rate was 3.9% (n = 15). Predictors of 30-day
mortality included preoperative left heart insufficiency (OR: 5.44,
95%CI: 1.63-18.17, p = 0.006), and postoperative stroke (OR:
197.11, 95%CI: 18.28-2124.93, p < 0.001). No predictor
for postoperative stroke and for composite endpoint was identified.
Conclusions: Considering that postoperative stroke rate and
mortality was acceptably low, single stage approach is an effective
option in such selected high-risk patients.
