Enterprise risk management and company ethics: The case of a short-term insurer in South Africa
Authors: K. Govender Krishna , Hassen‐Bootha R.
Published: April 2022

The aim of this study was to investigate the relationship between enterprise risk management (ERM) and company ethics, so as to understand the central role of risk management in improving company ethics. A 5-point Likert scale questionnaire was used to survey all 122 employees of an insurance organization. The level of ethics was measured by posing questions on the integrity, trustworthiness, and level of respect for top management, middle management, and non-management. The overall Cronbach’s alpha for the instrument measuring the level of ethics was 0.865, indicating that the instrument was highly reliable.The relationship between ERM controls and the level of ethics was determined using regression analysis, which produced a F value of 0.268 (p-value 0.607), which implied that there is no relationship between ERM controls and the level of ethics. It was also ascertained that ethics and compliance-related issues are not fully embraced by the organization. This implied that the insurance company is at a level of “nominal” risk management with uncoordinated, top-down risk management activities.Since ethics risk exposure resulting from poor corporate governance has been identified by the Institute of Risk Management as being a key contributor to many business failures in South Africa (and internationally), the exploratory findings can stimulate the leadership to institute polices to mitigate poor governance and risk as this will benefit all stakeholders.

Published: April 2022

The aim of the study was to demonstrate correlation between selected body condition indices of roe deer Capreolus capreolus (KFI, carcass weight) and the health status of the carcass (i.e. pathological changes found through external and internal examination of the carcass) of deer killed by hunting or road traffic. The study material consisted of 34 carcasses of roe deer found dead due to road collisions or obtained through hunting in accordance with the Principles of Individual and Population Selection of Game Animals in Poland. The results showed a significant correlation between the occurrence of disease signs (especially the presence of parasites) and the mean values of indices describing the individual condition of animals (carcass weight, KFI). This confirms that the preliminary examination of game harvested and animals killed by road collisions plays an important role in inhibiting the spread of epizootic diseases and in assessing the individual condition of animals.

Authors: Adisa Ajibola
Published: April 2022

Severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2)-infection is characterized by several malfunctions, including severe pulmonary disorders. Other metabolic consequences of SARS-CoV-2-infection have not been clearly defined. The present study assessed the status of blood gases, calcium metabolism, and electrolytes in SARS-CoV-2-infected individuals. One hundred and thirty-four newly diagnosed SARS-CoV-2-infected patients (age ranged 65-82years) attending Mullingar Regional Hospital, Republic of Ireland, participated in this study. They all had pulmonary disorders, pyrexia, body pains, etc. SARS-CoV-2 was confirmed in all patients using the RT-PCR molecular test method. The data of another 121 plasma samples of apparently normal, non-SARS-CoV-2-infected individuals taken before the emergence of Covid-19 served as controls. Levels of partial pressure of oxygen (pO2), saturated oxygen (SatO2), partial pressure of carbon dioxide (pCO2), and ionized calcium (Ca2+) were determined in all participants using the potentiometric method in RAPIDPOINT 500 Blood Gases System. Plasma vitamin-D was determined by immune enzymatically technique using DXi 800 Access Immunoassay System. Total calcium, phosphate, albumin, magnesium, and electrolytes were determined by the photometric method using Beckman Au680- Chemistry Analyzer. The results showed significantly (p<0.05) higher levels of pCO2 and HCO3- in COVID-19-patients compared to controls. Significantly(p<0.05) lower levels of pO2, SatO2, pH, K+, albumin, total-calcium, Ca2+, magnesium, and vitamin-D were observed in COVID-19 patients compared to controls. Corrected calcium, PO4-, Na+, and Cl- levels did not show significant (p>0.05) changes in the COVID-19-patients compared to controls. Abnormal blood gases, acidosis, hypomagnesaemia, hypoalbuminemia, hypovitaminosis D and calcium metabolic disorders could be features of COVID-19-disease.
Assessing Health Workers’ Adherence to the National Guidelines for Diagnosis and Treatment of Severe Malaria in Children (0-5 Years) - A Cross-Sectional Study of Hospitals in Kebbi State, Nigeria
Authors: Hassan Manir Jega
Published: April 2022

Adherence to treatment guidelines for severe malaria (SM) is a vital component of malaria control strategies. Non-compliance with treatment guidelines has implications on effective SM case management, particularly in children. The study aimed to assess Health workers’ adherence to the National Treatment Guideline for Diagnosis and Treatment of SM in children. A retrospective audit of patients’ records treated for SM from 1st January 2018 to 30th December 2019 was carried out through data abstraction in 5 General hospitals in Kebbi state. Also, questionnaires were distributed to health workers to assess their knowledge of the treatment guideline. Data from the hospitals were analyzed using SPSS version 23.0 and evaluated for HW’s adherence to treatment guidelines in the management of SM cases. A total of 377 cases of severe malaria (SM) were identified. All the cases (100%) were tested for malaria, with RDT being the commonest (60.2%) technique used, while 71 (18.83%) cases received intra-artesunate, 24 (6.36%) received intravenous quinine, and 41 (19.80%) received a follow-up dose of ACT. From the 50 health workers sampled, 38 (76%) of the responders established laboratory confirmation for SM, and all (100%) the responders had received one or more pieces of training on malaria treatment, with 28 (56%) respondents confirming the availability of National Treatment Guidelines for Diagnosis and Treatment of malaria. Findings suggest good compliance with the National Guidelines for Diagnosis and Treatment of severe malaria. However, there is a need to ensure the availability of a copy of the Guidelines in hospitals to sustain the present adherence observed.

A tanulmány annak a Rokonai Lajos Simonnak mutatja be élete első szakaszát, akire a hálás bakonyi leventék, mint vezetőre, pártfogóra, lelkiatyára gondolnak, ahogy azt márvány emléktáblán is megörökítették. Kevés forrás áll rendelkezésre a cisztercita szerzetes tanárról, aki önként elkísérte Zircről a 800 bevagonírozott leventét Németországba 1945. február 28-án. Ez az írás arra vállalkozik, hogy a tények töredékeiből, apró cserepekből építkezzen, és azokat kiegészítse társadalom-, kultúr- és mentalitástörténeti vonatkozásokkal. A választott megközelítésnek a jogosultságát a szocializációs közegek (agencies of socialization) fogalma adja (Giddens, 2006), amely a szocializáció és az enkulturáció színtereiként számításba vehető csoportokat vagy társadalmi kontextusokat jelöli. Giddens a szocializációs közeget mindig strukturáltnak tekinti, ami arra készteti az egyént, hogy a társadalmi gyakorlatban egy bizonyos keretrendszerben vegyen részt. Giddens úgy tartja, hogy az egyén életének egyes szakaszaiban ezen közegek közül több is szerepet játszhat, voltaképpen annyi szocializációs közeg létezik, ahány csoportban vagy társadalmi helyzetben az emberek életük egy számottevő részét eltöltik (Giddens, 2006, p. 143-147). A szocializációs hatással egyidejűleg informális tanulás is történik, így az adott keretrendszer hatása nemcsak az abban eltöltött időtől függ, hanem attól is, hogy milyen intenzitású a részvétel, milyen maga az egyén és mennyire reflektál a saját informális tanulására (Horváth H., 2011b, 2019). Rokonai életének főbb helyszínei ismertek, így ezeket a szociális közegeket vizsgálva kaphatunk kiegészítő információkat a fragmentált életrajzhoz. Itt kereshetjük, ezekben a keretrendszerekben, hogy az azokkal folytatott interakciók során milyen benyomások, jellemformáló hatások érték/érhették a cisztercita szerzetes tanárt. Az így nyert apró tényekből, következtetésekből, valószínűsítésekből próbáljuk körvonalazni Rokonai emberi, pedagógusi-szerzetesi vonásait.
Predicting hydraulic jump characteristics in a gradually expanding stilling basin with roughness elements by Sugeno Fuzzy Logic
Authors: Hassanpour Nasrin , Sadeghfam Sina , Crookston Brian , Abdollahpour Milad
Published: April 2022

The hydraulic behavior of a hydraulic jump can be challenging to estimate in order to design gradually expanding stilling basins with roughness elements on the bed. In this study, five dependent variables were identified that comprise: (i) the sequent depth ratio; (ii) the relative length of the jump; (iii) the relative roller length of the jump; (iv) the relative energy dissipation; and (v) the water surface profile. This study undertook a set of formulations based on the regression analysis and Sugeno Fuzzy Logic (SFL) to predict these variables based upon experimental data. Results demonstrate that the trained SFLs predicted the behavior of the dependent variables with the Nash–Sutcliffe Coefficient (NSC) greater than 0.96 in the testing phase. In contrast, the NSC values for the regression models are greater than 0.79. The higher accuracy of SFL is attributed to its capability in managing uncertainty and imprecise data owing to water surface profile oscillations of the hydraulic jump. Also, the results indicate that the prediction residuals for SFL are homoscedastic for all hydraulic parameters investigated except for the water surface profile, the prediction residuals of which for the regression equations are heteroscedastic.
Gallic acid enhanced bisphenol A degradation through Fe3+/peroxymonosulfate process
Authors: Zhang Lei , Qian Zheng , Wang Lingzhen , Jin Pengkang , Yang Shengjiong
Published: April 2022

Fe2+ is widely used for effective peroxymonosulfate (PMS) activation to eliminate refractory organics. However, Fe2+/PMS process suffers from difficulty on Fe2+ regeneration. Herein, we report an Fe3+/PMS process by using gallic acid (GA) as an effective promotor for efficient degradation of bisphenol A (BPA). The process exhibited considerable oxidation performance in the pH range of 3.0–10.0. Higher concentration of Fe3+/GA complex exhibited better BPA degradation performance whereby BPA could be completely degraded within 4 mins. Reactive oxidation species (ROS) quenching experiments, electron paramagnetic resonance (EPR) analysis, and methyl phenyl sulfoxide (PMSO) probing experiments revealed that sulfate radical (SO4•−), hydroxyl radical (HO•), and ferryl species are involved and responsible for the BPA degradation. Electrochemical analysis and density function theory (DFT) calculation explored that the self-oxidation of GA boosted the reduction of Fe3+ into Fe2+ for continuous activation of PMS. The GA boosted Fe3+/PMS system reached an intriguing mineralization efficiency of 86.4%. Findings from this work proposed references to improve the oxidation performance of Fenton-like reaction and provided new sight into the Fe3+/Fe2+ cycling.

Digital Twins (DTs) are on the rise as innovative, powerful technologies to harness the power of digitalisation in the WRRF sector. The lack of consensus and understanding when it comes to the definition, perceived benefits and technological needs of DTs is hampering their widespread development and application. Transitioning from traditional WRRF modelling practice into DT applications raises a number of important questions: When is a model's predictive power acceptable for a DT? Which modelling frameworks are most suited for DT applications? Which data structures are needed to efficiently feed data to a DT? How do we keep the DT up to date and relevant? Who will be the main users of DTs and how to get them involved? How do DTs push the water sector to evolve? This paper provides an overview of the state-of-the-art, challenges, good practices, development needs and transformative capacity of DTs for WRRF applications.
Hydroxylamine enhanced activation of peroxymonosulfate by Fe(III)/Cu(II) bimetallic for high-efficiency degradation of AO7
Authors: Zhang Ming , Zhang Kuo , Zhou Runjuan , Wang Jinpeng
Published: April 2022

In this study, a new type of iron/copper bimetallic combined with hydroxylamine (HA) activated peroxymonosulfate (PMS) was constructed to treat organic pollutants. Selecting the azo dye acid orange 7 (AO7) as the representative of organic pollutants, the new system can achieve nearly 100% degradation of AO7 within 5 min. The Fe(III)/Cu(II)/HA/PMS system mainly generates SO4·− to achieve the degradation of AO7 in acidic environment, while neutral and alkaline environments rely on ·OH. The presence of hydroxylamine accelerates the cycle of Fe(III)/Fe(II) and Cu(II)/Cu(I) in the system, and enhances the degradation ability of the system for organic pollutants. The addition of trace Cu(II) (1 μM) enhances the ability of a single Fe(III)/HA/PMS system to degrade AO7 in neutral and alkaline environments without causing secondary copper pollution. The common inorganic anions Cl− and NO3− in water have almost no effect on the degradation of AO7 in the system. The constructed Fe(III)/Cu(II)/HA/PMS system is an efficient and clean organic pollutant wastewater treatment process, which has very promising application prospects.

Structure-Activity Relationships of Amino Acid-Containing lntegrin Antagonists
Authors: Scarborough Robert M.
Published: April 2022

Interest in the development of specific antagonists of the 3 family of integrins
{platelet aub3 and the vitronectin receptor av3 ) has been principally driven by efforts to design
more potent antithrombotic agents than either aspirin or the thienopyridine-type ADP receptor modulators. The platelet fibrinogen receptor (aub3) and the vitronectin receptor (av 3) bind the RGD tripeptide sequence found within adhesive ligands. Because of this, many approaches to
antagonists of 3 receptors have utilized an RGD mimetic to identify antagonists. lntegrin antagonists of many structurally diverse classes have been discovered. One of the larger 3 integrin antagonist classes employs -amino acids to mimic the aspartate residue of the RGD mimetic. Structure-activity investigations have revealed the potent activity of agents which have
substituents appended to both the a and position of the -amino acid units of these antagonists. Several clinical candidates targeting platelet a11 b3 contain these -amino acid units and are currently being evaluated clinically.

Published: April 2022

The peptide calcitonin (CT) was initially discovered in 1962 as a novel hypocalcemic hormone. This hypocalcemic response was principally due to a potent inhibitory action of CT on osteoclast mediated bone resorption and it is this action which underlies its widespread clinical use for the treatment of bone disorders, including Paget's disease, osteoporosis and hypercalcemia of malignancy. In this article we review the basic physiology of CT action, structure-function studies on CT peptides, cloning of CT receptors and the identification of isoforms of the receptor derived from alterative splicing of the receptor mRNA. We also review the state of understanding on CT receptor mediated signaling and receptor regulation, along with developing concepts of how CT peptides interact with the receptor, including how the receptors may interact with receptor activity modifying proteins to produce novel phenotypes. Finally, current therapeutic use is reviewed, and the potential for expanded use that may come with advances in delivery of peptides or CT mimetics.
Dietary Lifestyle of Clinical Nutrition Students Compared with That of
Age-Matched Non-Medical Students
Authors: Hakim Noor A. , Alwagdany Demah A. , Hammad Jehan M. , Kattan Maram F. , Mannan Shahad A.
Published: April 2022

Background:

There is an assumption that clinical nutrition (CLN) students should
have better nutrition and health statuses and practice healthier lifestyles than other students.
However, the effect of pursuing nutritional studies on student dietary lifestyle is not well known.

Objective:

To investigate differences in nutritional status between CLN-major and Administration/
Humanities-major (AHM) students as well as determine their sources of health and nutrition-
related information.

Method:

This is a descriptive and cross-sectional study in which CLN and AHM (mainly English
and Arabic majors) students were recruited. Anthropometric measurements were taken, and
a questionnaire was administered to assess their dietary lifestyle.

Results:

In total, 160 female students (CLN, 86; AHM, 74) participated in the study. Most students
from both groups (>44%) were within the normal body mass index (BMI) range (18.5-24.9
kg/m2); no CLN students had class II or III obesity. No significant difference in BMI between the
two groups was observed. CLN students tended to consume breakfast and snacks more than
AHM students. Daily fruit and vegetable consumption was significantly higher among CLN than
AHM students. No significant difference was found in fried food or water intake between the
two groups. Additionally, CLN students were more involved in high-intensity exercise than their
counterparts.

Conclusion:

Our findings suggest that health status and dietary lifestyle among CLN students are
influenced by their study major. Obesity is less prevalent, and consumption of healthy foods,
such as fruits and vegetables, is higher among CLN students. Future studies investigating the
long-term effect of studying CLN on lifestyle and social relations with family and friends are
warranted.

Authors: Sadhu Surya Prabha , Yarla Nagendra Sastry , Pragada Rajeswara Rao , Konduri Prasad
Published: April 2022

Background:

Saccharumoside-B and its analogs were found to have anticancer potential
in vitro. The present study reports acute toxicity, molecular docking, ADMET profile analysis,
and in vitro and in vivo anti-inflammatory activity of saccharumoside-B for the first time.

Methods:

The in vitro enzyme inhibitory activity of saccharumoside-B on PLA2, COX-1, COX-2,
and 5-LOX enzymes was evaluated by the cell-free method, and its effect on TNF-α, IL1β, and IL-
6 secretion levels in LPS stimulated THP-1 human monocytes was determined by ELISA-based
methods. The anti-inflammatory activity was evaluated in vivo by carrageenan-induced rat paw
edema model. To test its binding affinity at the active site pockets of PLA2 enzymes and assess
drug-like properties, docking experiments and ADMET studies were performed.

Results:

Saccharumoside-B showed selective inhibition of the sPLA2 enzyme (IC50 = 7.53 ±
0.232 μM), and thioetheramide-PC was used as a positive control. It showed significant inhibition
(P ≤ 0.05) of TNF-α, IL-1β, and IL-6 cytokines compared to the positive control dexamethasone.
Saccharumoside-B showed a dose-dependent inhibition of carrageenan-induced rat paw edema,
with a maximum inhibition (76.09 ± 0.75) observed at 3 hours after the phlogistic agent injection.
Saccharumoside-B potentially binds to the active site pocket of sPLA2 crystal protein (binding
energy -7.6 Kcal/Mol). It complies with Lipinski’s Rule of Five, showing a promising safety profile.
The bioactivity scores suggested it to be a better enzyme inhibitor.

Conclusion:

Saccharumoside-B showed significant PLA2 inhibition. It can become a potential
lead molecule in synthesizing a new class of selective PLA2 inhibitors with a high safety profile in
the future.

Lawsonia inermis on Croton Oil Induced Hemorrhoidal Rats
Authors: Nallajerla Sai Krishna , Ganta Suhasin
Published: April 2022

Background:

Hemorrhoids are a common recto-anal disorder commonly known as piles or tissue clumps in the rectum. In normal individuals, they were known as anal cushions. In the anus, they are composed of rectal blood vessels, muscles, and elastic fibres when bulged,it can cause bleeding, constipation, itching, severe pain, and bleeding in the anus. Inflammation of the anal cushion remains major pathogenesis for the development of hemorrhoids. Inflammatory mediators like neutrophils, TNF-α, and IL-6 seem to play a major role in the development of disease.

Objective:

This study aims to carry out the ethanolic leaf extract of Lawsonia inermis (L. inermis) and evaluate its anti-hemorrhoidal activity both invitro and in vivo. Furthermore, Molecular Docking was performed on the crystal structure of COX-2 with the selective compound 23d-(R) (PDB ID: 3NTG) protein.

Methods:

The current study is to estimate an anti-inflammatory mediated anti-hemorrhoidal activity of ethanolic leaf extract of L. inermis at different doses of 200 mg/kg/ir and 400 mg/kg/ir in croton oil-induced hemorrhoidal rats. Pilex ointment is taken as a reference standard in the present study. Evan's blue extravasation technique were applied in the study to quantify the proinflammatory protein.

Results:

From the study results, a dose-dependent effect was found for ethanolic leaf extract of Lawsonia inermis at 200 mg/kg and 400 mg/kg causing a significant reduction of serum Pro-inflammatory mediators TNF-α, IL-6, and plasma neutrophils in croton oil-induced hemorrhoidal rats.

Conclusion:

Studies represented that the plant extract can significantly inhibit protein denaturation of egg albumin in invitro and has a beneficial role in anti-hemorrhoidal agent.
The Potential Role of Gut Microbiota in the Pathogenesis of Type 2 Diabetes
Mellitus via Epigenetics and Inflammasome
Authors: Sharma Bunty , Kumar Aman , Sharma Ujjawal , Pal Deeksha , Prashar Sourabh
Published: April 2022

The gut microbiota that comprises over 100 trillion microorganisms with a weight of
about 1-2 kg is regarded as one of the most crucial players in the regulation of the metabolic
health of host organisms. In recent years, the incidence of type 2 diabetes mellitus (T2DM),
characterized by high levels of sugar in the blood, has been exponentially increasing due to
obesity and other lifestyle risk factors. It was shown that dysbiosis, change in the overall
composition, and diversity of gut microflora can result in T2DM. Conversely, the microbial
composition can also influence the epigenetics of the host organism (DNA methylation as well
as histone modifications), which might have a potential effect on the metabolic health of the
individual. Another mechanism of gut microbiota in the development of T2DM is through the
involvement of nucleotide-binding oligomerization domain, Leucine-rich Repeat, and Pyrin
domain containing 3 (NLRP3) inflammasome, a part of the innate immune system. NLRP3
inflammasome produces inflammatory cytokines, promoting the secretion of microbial antigens
in the intestinal epithelium. Therefore, it is important to understand the possible connecting link
between gut microbiota and T2DM that might help in the modulation of gut microflora to better
understand the disease. In this review, the role of gut microbiota in the pathogenesis of T2DM
will be discussed.

Published: April 2022

Background:

Chronic Pain (CP) is a crucial determinant for disability in older adults. CP amplifies the impact of other common age-related diseases and increases cardiovascular risk. Physical exercise can improve CP. Randomized Controlled Trials (RCTs) with high-intensity exercise in older adults excluded people with Moderate Chronic Illness (MCI) and CP.

Objective:

This study aimed at evaluating in an RCT whether moderate exercise training can improve chronic pain in a sample of older adults, including people with MCI, and if any modification persists over time.

Methods:

A sample of 120 older adults was randomly selected for a moderate-intensity exercise program or cultural activities (control group). Chronic pain was assessed at t0, at t12 (end of the trial), and t48 weeks, by means of the Italian version of the SIP-Roland Scale.

Results:

Seventy-nine participants completed the follow-up (age 72.3±4.7, women 55.3%). At the end of RCT, an improvement in the SIP scale score was found in the exercise group (p=0.035), showing a lower score than the control group; this difference was not maintained at 48 weeks (p=0.235).

Conclusion:

Our study highlighted that a moderate-intensity exercise intervention reduced chronic pain in older adults, but this effect disappeared at follow-up after 36 weeks from the end of the training program. These findings suggested that such kinds of programs, easily accessible to old people even with MCI, should be implemented and supported over time, thus promoting active aging and preventing CP of age-related diseases.

An Unsteady Nanofluid Flow Past Parallel Porous Plates: A Numerical
Study
Authors: Mondal Sabyasachi , Mburu Zachariah M. , Sibanda Precious
Published: April 2022

Background:

This study investigates an unsteady, two-dimensional, incompressible viscous
boundary layer flow of an electrically conducting nanofluid past parallel plates. The plates are permeable
to allow both suction and injection to take place. It is assumed that viscosity, thermal conductivity and
mass diffusivity of the nanofluid vary with temperature. The novelty of this study is in consideration of
the combined effects of chemical reaction, permeability, externally applied magnetic field, and
momentum diffusivity on the flow varibles. The magnetic field force is significant because it provides
information regarding the boundary layer characteristics.

Methods:

The highly nonlinear partial differential equations are solved numerically using the newly
developed bivariate spectral quasilinearization method (BSQLM) along with varying thermal and
concentration boundary conditions. The BSQLM method is an innovative technique that is more reliable
and robust as it demands fewer grid points and has a global approach to solving PDEs.

Results:

An analysis and comparison of results with existing literature are reported. Excellent agreement
has been found between our results and those previously published. Among the findings, we show, inter
alia, a significant increase in the profiles for fluid velocity, temperature and concentration with an
increase in the chemical reaction, applied magnetic field, and thermal radiation. The BSQLM converges
fast and is computationally efficient when applied to boundary layer problems that are defined on a large
computational domain.

Conclusions:

A numerical study on nanofluid flow between parallel porous plates has been carried out,
and here are the key findings:
1. Heat flux is directly related to thermal radiation, the applied magnetic field, permeability, and the
chemical reaction involved.
2. Mass flux increases with increased chemical reaction, permeability, and the magnetic parameters.
3. The nanofluid concentration is directly related to the Prandtl and magnetic numbers and inversely
related to the Reynolds number and chemical reaction.
4. The skin-friction coefficient reduces with higher values of magnetic field and permeability parameters
and increases with an increment in thermal radiation and chemical reaction.
5. The BSQLM has a high convergence rate with high accuracy.
SMBF: Secure Data Transmission using Modified Bloom Filter for
Vehicular Ad Hoc Networks
Authors: Kumar Rajeev , Kumar Dilip , Kumar Dinesh
Published: April 2022

Objective:

Privacy in VANETs commands short-lived pseudonyms since the nodes
are very mobile. It results in big computational overheads during secure communication between
vehicles, which could place the safety of people and vehicles at risk. To overcome such a
limitation, we are using the validation approach of pseudonyms based on Bloom Filter, which
provides less computational overheads than other authentication procedures. A complete end-toend
system is developed in three phases: authorization, clustering, encryption, and decryption
phase, to establish secure transmission of data in VANETs.

Methods:

The authorization phase uses Bloom’s Filter authentication based on the pseudonym
scheme. Based on the distributed parameters related to vehicles, clusters of vehicles are created
to save power and bandwidth in communications. These clusters are chained to the next cluster
with the help of the cluster head to share the information. First, only authenticated vehicles that
are regular travelers on the road segment are allowed to become part of the cluster. SMBF
ensures that any vehicle that is not a frequent traveler on the given road segment is not taking
part in the communication process. Clustering is used to ensure the speed of communication.

Results:

The proposed scheme results are compared with other state-of-art techniques in
VANETs. The analysis indicates that the storage and computational processing requirements are
reduced by 28%, resulting in decreased communication costs.

Conclusion:

The proposed authentication process stores the pseudonyms in the certificate
authority database. Hence, more memory requirements are required to maintain this technique.
Overall, the performance of SMBF needs to be tested under different types of attacks.
Role of Cotton as Nesting Material in Female Mice as a Behavioral Indicator
for Pup’s Health
Authors: Srivastava Rajnish , Rastogi Mansi
Published: April 2022

Background:

Nesting is an essential neuropsychological motor behavior that helps conserve
heat for reproduction and shelter building to protect offspring from environmental change.

Aim:

The aim of the present study was to investigate how putting cotton in the cage influenced the
nesting behavior of female mice.

Objective:

The objective of the present work is to validate and establish the role of cotton as nesting
material.

Materials and Methods:

The female mice (n=25), after monogamous mating, were kept individually in
a separate cage for the entire gestation period to prepare for delivery. Sterile cotton was kept inside the
cage after immediate delivery to observe the nesting and burrowing neuropsychological behaviour. The
quality of the resulting nest was scored by a definitive 5-point nest scoring scale as 0 for no nest, 1 for
the flat nest, and 2 onwards for nests covering the offspring by mice. Furthermore, the neurobehavioral
maternal health was also evaluated in terms of grooming, rearing activity, mean time spent by the dam,
frequency of nurturing and mean time spent on the nest for each mouse for 10min daily for 15 days.

Results:

Based on scoring, out of 25 female mice, 16 were found to show a maximum score of 5, as
they build a nest with which they reveal better neuropsychological nurturing behavior as compared to
the remaining 4 with a score of 4 to protect their offspring from environmental change to maintain a
homeostatic microenvironment.

Conclusion:

Cotton was considered a suitable choice as nest-building material, which was better utilized
by the swiss albino mice. It also improves nesting and burrowing performance, observed in the
home cage, proving to be a valuable and easy-to-use tool for assessing motor impairment due to brain
damage as well as neurobehavioral changes.
