Cytogenotoxicity Assessment of Aqueous Extracts of Rauvolfia vomitoria (Apocynaceae) on the Male Germ Line Cells of the Pest Grasshopper Zonocerus variegatus (Orthoptera: Pyrgomorphidae)

Cytogenotoxic effects of aqueous extracts of Rauvolfia vomitoria Afzel (Apocynaceae) stem bark were assessed on male germ line cells of the grasshopper Zonocerus variegatus. Concentrations of 0, 10, 15 and 20 μg/ml of infused and macerated aqueous extracts of R. vomitoria were prepared and administered through injection to the grasshoppers. Grasshoppers were dissected after 72 hours of incubation and the different parameters were then evaluated. Results revealed significant Original Research Article Ingrid et al.; AJBGMB, 7(2): 19-31, 2021; Article no.AJBGMB. 65339 20 (p < 0.05) reduction of the length and the width of testis follicles with increasing concentrations of the two aqueous plant extracts. Meiosis analysis revealed a significant (p < 0.05) increase in meiotic abnormalities with increasing concentrations of the two aqueous plant extracts. Infused and macerated aqueous extracts of R. vomitoria at different concentrations did not modify the karyotype of Z. variegatus. Cyclophosphamide (CP) induced chromosomes aberrations and significantly (p < 0.05) reduced the mean chromosomes complement number which ranged from 2n= 19.00 ± 0.00 (controlled individuals) to 2n= 17.60 ± 1.82 (CP treated individuals). These observations indicate that infused and macerated aqueous extracts of R. vomitoria stem bark could induced cytogenotoxicity on the germ line cells of the grasshopper Z. variegatus. These results also confirm the utilization of CP as positive control in chromosomes aberration assays on grasshoppers.
Long term effects of fertilizer and manure application on productivity, sustainability and soil properties in a rice-rice system on Inceptisols of Eastern India

ABSTRACT Long-term application of fertilizer and manure can affect soil properties with implications on the productivity and sustainability of crops. Data from a long-term fertilizer experiment at Bhubaneswar, India was used to study the impact of seven treatments viz. control, application of recommended dose of NPK (NPK), 150% NPK (1.5 NPK), NPK + Zn (NPKZn), NPK + FYM (NPKFM), NPK + Zn + B (NPKZnB) and NPK + Zn + S (NPKZnS) on productivity, sustainability (in terms of sustainable yield index (SYI)), soil properties (physical, chemical and biological) and soil organic carbon (SOC) sequestration of rice-rice cropping system. Results revealed that application of NPKFYM improved the average grain yield and SYI of wet and dry season rice and the system by 36.3, 21.6, and 28.3% and 28.8, 17.1, 22.8%, respectively, over NPK alone. Application of NPKFYM improved soil fertility by stimulating microbial activity, improving soil physical health, resisting drop in pH to more acidity and improving CEC and macro- and micro-nutrients levels. NPKFYM also sequestered higher SOC than NPK alone. Therefore, application of NPKFYM can be recommended for sustaining the productivity of the rice-rice system with improvement of soil health under Inceptisols of Eastern India.
Measuring Disruptions in Last-Mile Delivery Operations

The rapid growth of urbanisation and e-commerce has increased the number of home deliveries that need to be made in retail operations. Consequently, there is also an increase in unexpected incidents, such as adverse traffic, unavailability of parking space, and vehicle breakdowns. These disruptions result in delays, higher costs, and lower service levels in the last-mile delivery operation. Motivated by free, innovative, and efficient tools, such as the Google application programming interface (API) and Google OR, we built a model to measure the impact of disruptions in the last-mile delivery operation. Our model considers customers’ geographic information, speed estimation between nodes, routing optimisation, and disruption evaluation. Disruptions are considered here as external factors such as accidents and road works that imply the closure of or slow access to certain roads. Computational experiments, based on a set of real data from three different cities around the world, which contrast in size and characteristics (i.e., Boston, US; Bogotá, Colombia; and Pamplona, Spain), were conducted to validate our approach. The tests consider 50 different instances of up to 100 customers per city and analyse the impact of disruptions in terms of travelled time and distance. Our results provide managerial insights for key stakeholders (i.e., carriers, consumers, and government) to define policies and development plans that improve the resilience and capabilities of cities’ transportation systems.
Morphoanatomical study, seasonal variation, and larvicidal activity of volatile oils from the leaves of Campomanesia pubescens (DC.) O. Berg (Myrtaceae)

The aim of this study was to perform from the morpho-anatomical study, physicochemical characterization, chemical composition, seasonal variability and larvicidal activity of the volatile oils of Campomanesia pubescens (DC.) O. Berg leaves. The botanical material was collected in Hidrolândia, Goiás. Morpho-anatomical characterization and phytochemical screening were performed by conventional methods. Leaf powders were submitted to hydrodistillation in the Clevenger apparatus and the identification of the chemical components of the volatile oils obtained was done by GC-MS. The larvicidal activity was carried out with third-stage larvae of the Aedes aegypti. The leaf blade, the main vein, and the young stem have a uni-stratified epidermis covered by a cuticle. The mesophyll and cortical parenchyma of the main vein and young stem have secretory cavities and idioblasts with crystals. The main rib contains a bicolateral bundle in an open arch. The young stem has a discontinuous band of sclerenchyma external to the phloem cells. Most volatile oil compounds are spathulenol, caryophyllene oxide, α-macrocarpene, and z-caryophylleneIn phytochemical analysis, tannins, digitalis, flavonoids, and total phenols were detected. The content of volatile compounds was 7.36%, that of total ash was 1.77%, and that of mucilage was 3.52 ml. The volatile oil at the concentration used was inactive against Ae aegypti larvae. The present study contributes to the taxonomic knowledge of the species and provides parameters for quality control of the plant raw material. This work represents the first description of the chemical compounds and seasonal variability of volatile oils from C. pubescens leaves collected in Goiás state.
Decision Support for Removing Fractured Endodontic Instruments: A Patient-Specific Approach

The instrumental fracture is a common endodontic complication that is treated by surgical or non-surgical removal approaches. However, no tool exists to help the clinician to choose between available strategies, and decision-making is mostly based on clinical judgment. Digital solutions, such as Finite Element Analysis (FEA) and Virtual Treatment Planning (VTP), were recently proposed in maxillofacial surgery. The aim of the current study is to present a digital tool to help decide between non-surgical and surgical strategies in a clinical situation of a fractured instrument. Five models have been created: the initial state of the patient, two non-surgical removal strategies using a low or high root canal enlargement, and two surgical removal strategies using a 3- or 6-mm apicoectomy. Results of the VTP found a risk of perforation for the non-surgical strategies and sinus proximity for surgical ones. FEA showed the lowest mechanical risk for the apicoectomy strategy. A 3-mm apicoectomy approach was finally chosen and performed. In conclusion, this digital approach could offer a promising decision support for instrument removal by planning the treatment and predicting the mechanical impact of each strategy, but further investigations are required to confirm its relevance in endodontic practice.
The relationship between perceived social support and healthy life style in women with breast cancer in Iran

Background: Social support and life style are important for cancer patients, and many psycho-oncological studies have shown that social support improves their ability to cope with the cancer.Aims: The purpose of this study was to determine the relationship between perceived social support and healthy life style in women with breast cancer in Sabzevar, Iran 2020. Methods: In this cross-sectional study 300 of women with breast cancer are examined in Iran 2020. Questionnaires of Health Promoting Lifestyle Profile-II and Sarason’s Social Support were assessed. The data were analyzed through Pearson correlation coefficient analysis and descriptive statistics. Results: A positive relationship was found between the subscales of HPLP II and social support network total score (r=0.62, P =0.001), spiritual growth (r=0.56, P =0.001), interpersonal relations (r=0.61, P =0.001) and stress management (r=0.61, P =0.002). Strong relationship was found between the perceived satisfaction from social support network subscale and the HPLP II total score (r=0.71, P<0.001). Conclusions: The study suggests that the social support network would be strong relation to the healthy life of style among breast cancer patients. Thus, it would be beneficial to pay attention to providing social support to breast cancer patients, particularly to those who are more vulnerable. Furthermore, investigation of the most effective and efficient methods to deliver social support interventions would be worthwhile.
High-Temperature Synthesis of Metal–Matrix Composites (Ni-Ti)-TiB2

Currently, metal–matrix composite materials are some of the most promising types of materials, and they combine the advantages of a metal matrix and reinforcing particles/fibres. Within the framework of this article, the high-temperature synthesis of metal–matrix composite materials based on the (Ni-Ti)-TiB2 system was studied. The selected approaches make it possible to obtain composite materials of various compositions without contamination and with a high degree of energy efficiency during production processes. Combustion processes in the samples of a 63.5 wt. % NiB + 36.5 wt. % Ti mixture and the phase composition and structure of the synthesis products were researched. It has been established that the synthesis process in the samples proceeds via the spin combustion mechanism. It has been shown that self-propagating high-temperature synthesis (SHS) powder particles have a composite structure and consist of a Ni-Ti matrix and TiB2 reinforcement inclusions that are uniformly distributed inside it. The inclusion size lies in the range between 0.1 and 4 µm, and the average particle size is 0.57 µm. The obtained metal-matrix composite materials can be used in additive manufacturing technologies as ligatures for heat-resistant alloys, as well as for the synthesis of composites using traditional methods of powder metallurgy.
Electrochemical Corrosion and Metal Ion Release Protective Efficiency of the Multilayer TaN Coatings on CoCrMo Biomedical Alloy

CoCrMo alloy is widely used in artificial orthopedic joint applications due to its high mechanical properties. But, high levels of the metal ion release from alloy surfaces cause variable toxic and allergic effects on the patient in vivo use. This case restricts the lifetime of the implant and results in the failure of the artificial joint. In order to enhance the corrosion resistance and to decrease the metal ion release, alloy surface was multilayer-coated by closed field unbalanced magnetron system. The protective efficiency of the coatings was determined by potentiodynamic polarization tests and static immersion tests were performed for 45, 60 and 90 days in the simulated body fluid in order to understand the effect of the coatings on the metal ion release. The metal ion concentrations in the simulated body fluids were determined by using inductively coupled plasma mass spectrometry device. The electrochemical corrosion results showed that the multilayer coatings provided 93 % protective efficiency in terms of corrosion resistance. Multilayer coatings decreased the metal ions release levels significantly, especially Co leaking was decreased approximately 52 times compared to uncoated samples.
Open Research

Recent investigations of meteorites thought to originate from the asteroid 4 Vesta have suggested an early accretion of water on rocky bodies in the inner Solar System from a carbonaceous chondrite-like source. However, these studies have been based on the hydrogen isotope compositions ( d D) of late-crystallizing apatite grains in eucrites that likely do not record the primary magmatic composition. We have determined the d D and H 2 O concentrations in some of the earliest-formed silicates (clinopyroxenes) from several eucrites with the goal of constraining the hydrogen isotope composition of their source reservoir on their parent body. The H 2 O concentrations in clinopyroxenes from eucrites Juvinas, Stannern and Tirhert range from 5 to 18 l g/g, with a weighted average d D of –263 ± 70 ‰ . Their apatites and whitlockites exhibit a higher weighted average d D of – 165 ± 73 ‰ , possibly as a result of H 2 degassing during or after phosphate crystallization. Thermal metamorphism of these eucrites has most probably resulted in the loss of H, and an increase in their original d D values. While the weighted average d D value for the eucrite clinopyroxenes reported here is inferred to reﬂect an upper limit for the isotopic composition of the silicate mantle reservoir on their parent asteroid 4 Vesta, the average d D value of Stannern clinopyroxenes is considered to be closest to the initial d D of the source mantle (i.e
The PCPDTBT Family: Correlations between Chemical Structure, Polymorphism, and Device Performance

We highlight the influence of processing conditions on polymorphism and structure formation on the mesoscale for the family of PCPDTBT polymers with branched alkyl side chains. Direct correlations of morphology to the chemical structure and to transistor device performance are established. We found that up to four different packing motifs could be realized depending on the polymer derivative and the processing conditions: amorphous, π-stacked, cross-hatched and dimer-containing polymorphs. While C- and F-PCPDTBT display similar packing behavior organizing in π-stacked and dimer-like structures, Si-PCPDTBT gives rise to cross-hatched structures upon simple deposition from solution. The observed differences in chain packing for C-/F-PCPDTBT versus Si-PCPDTBT are attributed to differences in backbone conformations and aggregation behavior in solution. The effect of polymorphism on charge transport is probed using field-effect transistors, in which both π-stacked and cross-hatched polymer chain arrangements y.
Integrated Business Intelligence and Analytics: The Case of the Department of the Navy

From a stakeholder perspective, this study explores the viability of data analytics as a tool in government fraud prevention. Using an interview methodology, we analyze the implications of business intelligence and analytics fraud tools on procurement stakeholders. We find that implementing and integrating business intelligence and fraud program streamlines processes by consolidating information and presenting data within a unique program. The functioning data analytics program increases our stakeholders' confidence level without alleviating their responsibility to perform due diligence in their management functions. Our stakeholders recognized a potential increase in workload; however, they acknowledged no perceived increase in undue administrative burden.
How Memory Switches Brain Responses of Patients with Post-traumatic Stress Disorder

Abstract To characterize the brain responses to traumatic memories in post-traumatic stress disorder (PTSD), we conducted task-employed functional magnetic resonance imaging and, in the process, devised a simple but innovative approach—correlation computation between task conditions. A script-driven imagery task was used to compare the responses with a script of the patients’ own traumatic memories and with that of tooth brushing as a daily activity and to evaluate how eye movement desensitization and reprocessing (EMDR), an established therapy for PTSD, resolved the alterations in patients. Nine patients with PTSD (seven females, aged 27–50 years) and nine age- and gender-matched healthy controls participated in this study. Six patients underwent the second scan under the same paradigm after EMDR. We discovered intense negative correlations between daily and traumatic memory conditions in broad areas, including the hippocampus; patients who had an intense suppression of activation during daily recognition showed an intense activation while remembering a traumatic memory, whereas patients who had a hyperarousal in daily recognition showed an intense suppression while remembering a traumatic memory as a form of “shut-down. ” Moreover, the magnitude of the discrepancy was reduced in patients who remitted after EMDR, which might predict an improved prognosis of PTSD.
A Multireceiver Wireless Power Supply System with Power Equalization in Stereoscopic Space

With the rapid development of wireless power transfer (WPT) technology, the traditional single-transceiver WPT system has become more and more advanced; however, it is still difficult to meet its extensive application requirements. Aiming at the wireless charging of mobile phones in public places, electric vehicles (EVs) in multistorey garages, and electronic shelf labels (ESLs) in supermarket merchandise shelves, a multireceiver wireless power supply system with power equalization is proposed. The condition of power equalization is derived according to the equivalent circuit of the proposed WPT system, and the received power can be equally maintained by adjusting the transceiver loop resistance when the total load number or transmission distance changes. A simulation model is established to evaluate the electromagnetic environment of the proposed WPT system, and the results comply with the electromagnetic safety of the ICNIRP-2018 guidelines. Finally, the experimental results show that the power differential rate that meets the power equalization condition is 13 to 17% lower than that of the unsatisfied rate, which verifies the effectiveness of the proposed system in terms of power equalization.
Determinants of Corporate Anti-Corruption Disclosure: The Case of the Emerging Economics

Corruption is a key factor that affects countries’ development, with emerging countries being a geographical area in which it tends to generate greater negative effects. However, few empirical studies analyze corruption from the point of view of disclosure by companies in this relevant geographical area. Based on a regression analysis using data from the 96 large companies from 15 emerging countries included in the 2016 International Transparency Report, this paper seeks to understand what determinants affect such disclosure. In that context, this paper provides empirical evidence to understand the factors that influence reporting on anti-corruption mechanisms in an area of high economic importance that has been little studied to date, pointing to the positive effect of press freedom in a country where the company is located and with the industry being the unique control variable that strengthens this relationship.
Energy‐Based Scenarios for Great Thrust‐Type Earthquakes in the Nankai Trough Subduction Zone, Southwest Japan, Using an Interseismic Slip‐Deficit Model

We propose a new energy‐based method to construct rupture scenarios for anticipated megathrust earthquakes by using an interseismic slip‐deficit model. Our method bridges the gap between two well‐known approaches, namely, kinematic and dynamic modeling. We construct the source model as a static‐slip distribution, greatly reducing the computational load, and then examine whether the model follows the mechanics of faulting from the perspective of the energy balance of fault rupture. To quantify the energy balance, we introduce “residual energy,” which is defined as the difference between the strain energy released by the fault slip and the energy dissipated on the fault. Positive residual energy is a necessary condition for earthquake generation, which means that even if slip deficits accumulate, an earthquake does not occur unless the strain energy accumulation exceeds the dissipated energy. We apply the method to interplate earthquakes in the Nankai trough subduction zone, southwest Japan. Assuming a stress accumulation time of 150 years, 5 out of 10 scenarios meet the necessary condition, and one of these models can explain the crustal deformation of a historical Nankai earthquake. The significant amount of strain energy released by a rupture off Cape Muroto makes the scenario involving rupture of the whole subduction zone possible. The estimation of residual energy suggests that fault ruptures reaching the Nankai trough require more strain energy than buried ruptures. All of the scenarios eventually meet the condition, because the strain energy increases more with time than the fracture energy predicted from empirical scaling relationships.
Understanding information systems success: a hybrid view

ABSTRACT The information systems (IS) success model, introduced in 1992, provided IS research with a comprehensive set of dependent variables for project success. While the model addresses both process and variance considerations, the latter has dominated the research. Concurrently, the benefits of hybrid theories have been discussed in the literature, and there have been calls for an integrated view of IS success that includes the process perspective. We build on this momentum by presenting a hybrid model based on a longitudinal case study of the development and implementation of a patient-flow decision-support system at a large not-for-profit hospital. Our model remains true to the DeLone and McLean framing but elaborates on the process elements. The hybrid model expands our ability to analyse multiple dimensions of IS success and integrates diverse research findings into the IS success model, providing a revised version for future research to extend.
