Changes in selected properties of Calcic Chernozem due to cultivation of Robinia pseudoacacia and Quercus robur
Authors: Gorban Vadym , Huslystyi Artem
Published: July 2023

The results of a comprehensive study on the particle size distribution, soil organic matter (SOM) content, and plant-available water in Calcic Chernozem are presented, along with the impact of Robinia pseudoacacia L. and Quercus robur L. plantations on these indicators. The study revealed that Calcic Chernozem under steppe vegetation and Q. robur plantation exhibited a silty clay loam texture. However, under the influence of R. pseudoacacia plantation, the chernozem’s texture transformed into loam. The planting of R. pseudoacacia resulted in a noticeable decrease in SOM content, while the growth of Q. robur plantations led to an increase in SOM content. Furthermore, both R. pseudoacacia and Q. robur plantations contributed to an increased content of plant-available water in the 0–20 cm layer of chernozem. These findings highlight the more pronounced effect of R. pseudoacacia plantation on the particle size distribution, SOM content, and plant-available water in Calcic Chernozem compared to Q. robur plantation.

Authors: Mougui Ahmed , Belouaham Sara , El Bouchti Imane
Published: July 2023

Introduction

Neuropathic pain (NP) is believed to be a distinct subtype of pain associated with knee osteoarthritis (KO). This study aimed to determine the prevalence of NP in patients with primary KO and examine its correlation with various factors.

Methods

A cross-sectional study was conducted on 195 patients with primary KO who did not have the following conditions: knee surgery, infection, rheumatic diseases, peripheral and central neurological diseases, patients who received treatment for neuropathic pain in the past 6 months, diabetes, renal failure, and alcoholism. NP was evaluated using two standardized questionnaires, the Douleur Neuropathique 4 questions (DN4) and the painDETECT questionnaire.

Results

The majority of patients were female (87.5%), with a mean age of 59.15 ± 7.62 years. NP was detected in 55.9% of patients according to the DN4 questionnaire and in 50.7% of patients according to the painDETECT questionnaire. The DN4 score was positively correlated with age (p=0.041; rs=0.145), visual analogue scale (VAS)-pain at rest (p=0.009; rs=0.188), VAS-pain at movement (p=0.017; rs=0.173), Western Ontario and McMaster Osteoarthritis Index (WOMAC) pain score (p=0.030; rs=0.157), WOMAC stiffness score (p=0.000; rs=0.253), physical function WOMAC score (p=0.000; rs=0.271), total WOMAC score (p=0.000; rs=0.305), Lequesne score (p=0.002; rs=0.221), and negatively correlated with quadriceps circumference (p=0.008; rs=−0.210). Whereas, the painDETECT score was positively correlated with VAS-pain at movement (p=0.002; rs=0.220), WOMAC stiffness score (p=0.043; rs=0.147), physical function WOMAC score (p=0.017; rs=0.172), and total WOMAC score (p=0.012; rs=0.182). NP according to the DN4 was associated with quadriceps circumference (p=0.01), while the painDETECT score was associated with VAS- pain at movement scores (p=0.022) and total WOMAC score (P=0.001).

Conclusion

This study found that NP is common among patients with primary KO and is associated with more painful pathology and functional impairment. These findings highlight the importance of recognizing and managing NP in this population to improve patient outcomes.

Published: July 2023

OBJECTIVES. We investigated peripheric and central olfactory pathways on MRI in Chronic Obstructive Pulmonary Disease (COPD) patients and the relationship between olfactory measurements of COPD patients and thorax CT images of emphysema classification in them.

MATERIAL AND METHODS. In this retrospective study, cranial MRI of 42 adult patients with COPD and 42 healthy adults without COPD were included. In both groups, peripheral (olfactory bulb (OB) volume and olfactory sulcus (OS) depth) and central olfactory areas (insular gyrus and corpus amygdala areas) were evaluated. We classified thorax CT findings according to emphysema by size as 1 to 4.

RESULTS. In the present study, left OB volume of the COPD group was significantly lower than that in the control group (p<0.05). On the right side, there were no significant differences between OB volumes of the COPD and control groups. Although right OB volume values were found to decrease proportionally, they were not found to be statistically significant. Also, insular gyrus and corpus amygdala areas of the COPD group were significantly lower than those in the control group, bilaterally (p<0.05). OS depths of the COPD group were significantly higher than those in the control group, bilaterally (p<0.05). In males, the right OB volume values were higher than those in females (p<0.05).

CONCLUSION. In COPD patients, left OB volumes decrease and OS depths increase bilaterally, and central areas decrease bilaterally, regardless of the thoracic emphysema classification. It may be related to hypoxemia that causes airway inflammation; inflammatory mediators may be harmful to the olfactory neuroepithelium.

The coexistence of inflation and unemployment rates especially in developing economies has been generating a lot of debate among researchers concerning the validity of Phillip’s curve. The current study examines the validity of Phillip’s curve in the context of the BRICS countries comprises of Brazil, Russia, India, China, and South Africa using data from the World Bank database (2020) and analyzed using a random effect static panel regression analysis. We find that the unemployment rate and output negatively and significantly influenced the inflation rate in the BRICS countries, which validates Phillip’s curve. This implies that raising unemployment and output level may likely reduce inflation rate in the BRICS countries. We, therefore, recommend the need for policymakers to choose to either stabilize prices or reduce unemployment. Also, the need for government to reduce inflation by increasing output thereby generating employment for the people. The BRICS countries should focus more on the labor-intensive technique of production to reduce the cost of production, create jobs and reduce prices.

Published: July 2023

The article computes cost, revenue and profit efficiency scores of Indian Life Insurance companies during the period 2013-14 to 2020-21 by employing a Non-Parametric Approach, namely, Data Envelopment Analysis (DEA). The paper also examines the efficiency of Life Insurers across ownership by comparing Public and Private Insurance Sector. The concrete findings suggest that the overall performance of Life insurance companies in terms of economic efficiencies is not satisfactory. The average cost, revenue and profit efficiency is .527, .402 and .589 respectively which is far less than the yardstick of 1. The highest level of inefficiency subsists on the revenue side, which is in turn reflected in the average of profit inefficiency. Significantly inferior efficiency scores in the Private Sector seem to have marred the average efficiency scores of Insurance sector in India.

Metode PCR-RFLP merupakan salah satu metode untuk deteksi mutasi pada daerah D-loop DNA mitokondria. Metode ini menggunakan enzim restriksi untuk dapat memotong DNA mitokondria dan menghasilkan ukuran fragmen DNA yang berbeda-beda. Enzim restriksi memerlukan kondisi yang optimal untuk melakukan pemotongan DNA. Penelitian ini bertujuan untuk mengetahui kondisi optimal enzim restriksi agar dapat melakukan digesti pada daerah D-loop DNA mitokondria. Optimasi dilakukan dengan membuat dua kombinasi formula digesti (formula 1 dan 2) dan empat macam waktu digesti (2 jam, 4 jam, 6 jam dan overnight). Hasil penelitian menunjukkan optimasi dari lima macam enzim restriksi (HaeIII (BsuRI), HindIII, HinfI, MboI dan HpyP31 (DdeI)) didapatkan bahwa  ada perbedaan formula dan waktu digesti tergantung dari jenis enzim. Enzim HaeIII(BsuRI), HinfI dan MboI menunjukkan formula 2 merupakan formula optimal, sedangkan enzim HpyP31 (DdeI) formula 1 merupakan formula yang optimal. Waktu digesti 2 jam menunjukkan hasil optimal pada Enzim HaeIII(BsuRI), MboI dan HpyP31 (DdeI), sedangkan enzim HinfI waktu digesti optimal adalah 4 jam. Enzim HindIII tidak mendapatkan hasil potongan fragmen DNA setelah digesti, maka enzim HindIII tidak memiliki situs pemotongan pada daerah D-loop DNA mitokondria.

Published: July 2023

PURPOSE: To evaluate the HPV vaccine coverage in adolescents and young adults relatives of women with cervical cancer. METHOD: A Prospective study held in the oncology department at a tertiary referral Hospital, using an adapted form. RESULTS: Epidemiological data were collected from 102 women with CC and 59 family members between 9-21 years. The degree of kinship between these young woman and cancer patients treated at the Hospital in the study was daughter (56%), sister (3%), niece (22%) and granddaughter (19%). Most of these girls (81%) were instructed to carry out HPV prevention, with the school (39%) being the main responsible for promoting vaccination. Regarding the reasons for not performing the immunization, the lack of information about the vaccine was the most mentioned (63%). When asking the girls relatives if they would vaccinate their daughters, 17% said they would not and none of these relatives knew the function of the vaccine. CONCLUSION: despite advances in HPV vaccination programs, there is still a great deal of misinformation about the topic in the population, especially among family members of the target audience. The school was identified as the protagonist in access to information and can be used as a means of access to the vaccine for young women and information for their families.

Introduction The aim of this study was to evaluate the effect of different treatments on lower incisor (L1) inclination in patients with Class II malocclusion. Methodology 73 patients (39 females, 34 males) with Class II malocclusion were retrospectively collected from the postgraduate orthodontic clinic. All patients were treated at least with multibracket appliance (MBA) and Class II elastics (CLII) alone (control group), or in combination with the removable-functional appliance (RFA), fixed-functional appliance (FFA), or lingual arch (LA). Pre- and post-treatment L1-NB (mm), L1-GoGn (°) and L1-NB (°) values were analyzed. The analysis of the treatment effect in relation to the outcomes and time were done by the Propensity Score Matching (PSM) method using Cox regression and Survival analysis. Results Regarding L1-NB distance, patients treated only with CLII elastics have lower risk of incisor proclination, however, the risk may occur from the beginning of the treatment. FFA, RFA and LA present higher risk of incisor proclination, but this occurs later in time (hazard ratio HR= 0.4 RFA/0.22 FFA and LA). Concerning L1-GoGn angle, all treatments have high risk of proclination. However, RFA reduces the rate of risk (p=0.003) (HR=0.22), while FFA increases the rate of risk (HR=0.35). Conclusion Multibracket orthodontic treatment with CLII elastics alone produces unfavorable labial incisor inclination rapidly. Combination treatment of RFA with CLII elastics delays the occurrence of proclination, while FFA highly increases the risk of proclination. The use of the lingual arch retains the position of the dentition for longer time, however once the lower incisor proclination occurs, it deteriorates fast.

Background ‘Virtopsy’ is made up of two words ‘virtual’ and ‘autopsy’. ‘Virtual’ means digitally available, while ‘autopsy’ means examination of deceased to find out the cause of death. Objective This review aims to provide an overall view about virtopsy in forensic odontology. Data sources A narrative review was performed with a literature search in the PubMed and Google Scholar electronic databases. Study selection Reference lists included full papers of any study design, published in peer-viewed English till June 2022. Data extraction Current literature indicates various methods and applications of virtopsy in forensic odontology. Moreover, recent advances in forensic odontology are discussed. Data synthesis Virtopsy is a virtual alternative to traditional autopsy. Conventional autopsy has its own pitfalls as it is an invasive procedure and not socially as well as emotionally accepted in certain religions. Virtual autopsy is a better adjunct for conventional autopsy. Virtual autopsy has its own advantages as digital storage of data can be done. Virtopsy used in forensic odontology is known as ‘Virdentopsy’. Various equipment and robotic science have also developed in this field of Virdentopsy

Published: July 2023

Urbanization, industrialization and consumerization have increased pollution levels in our growing cities. The activities of the people on a mass scale during festivities and celebrations can aggravate the problems of the environment. Diwali is a community festival during which the bursting of crackers and lighting of lamps mark the celebration. The large-scale burning of pyrotechnics effuses large amounts of gaseous chemicals into the surrounding atmosphere and sounds emanating from low-explosive substances can culminate into high-decibel noises. An attempt is made in this study to evaluate the air quality, concentration and pathways of the dispersing substances arising from the bursting crackers at this community celebration in the city of Visakhapatnam. Data on diurnal variations, concentration and ratio of the pollutants, namely PM2.5, PM10, SO2, NO2, CO, ozone, benzene and toluene are gleaned from the CPCB data and vis-a-vis the air quality index was evaluated. The role of meteorological parameters is analyzed and the correlation of meteorological parameters [Temperature (TEMP), Relative Humidity (RH), Wind Speed (WS)] with various pollutants is assayed. Transportation, dispersal and pathways of the pollutants during the study period are depicted through HYSPLIT trajectories. Correlation among the pollutants is also assessed. The study reveals that the use of firecrackers during Diwali is a significant source of particulate matter (PM2.5, PM10) and other gaseous pollutants (SO2, NO2, CO, Ozone, Benzene and Toluene) in the ambient air, thereby impacting urban air quality during the sampling period.

Published: July 2023

The structural requirement for a conducting polymer is a conjugated π electron system. It can be easily oxidised or reduced by charge -transfer agents which are called dopants. In the present study, a new conducting polymer based on glyoxal and p-phenylene diamine was synthesized in DMF and was characterized by IR spectra, GPC and TGA. In-situ polymerization of glyoxal and p-phenylenediamine was done in DMF containing different amounts of PE. The D.C. conductivity and the effect of dopants like HC1O4, HCl and 12 on conductivity of each sample was studied. The D.C. conductivity of the samples increased on doping with HCI, HC1O4 and iodine while the D.C. conductivity of all blends decreased with increase in the amount of polyethylene.

On the synthesis of WS2 nanotubes: reaction mechanism revelation by in-situ scanning and ex-situ transmission electron microscopy
Authors: Kundrat Vojtech , Novak Libor , Zalesak Jakub , Bukvisova Kristyna , Kolibal Miroslav , Tenne Reshef
Published: July 2023

This study provides a comprehensive understanding of the WS2 nanotube synthesis mechanism by conducting in-situ SEM and ex-situ TEM analyses of the sulfidation reaction of W18O49 nanowhiskers. The formation of WS2 nanotubes initiates with the rapid passivation of the reactive tungsten suboxide surface, followed by the evaporation of the oxide core and pressure buildup inside the nascent nanotube. The compactness and defectiveness of the initial passivation layer, gas pressure differences, and the structure of the W18O49 nanowhisker play crucial roles in determining the morphology of the final WS2 nanotubes. Additionally, this work elucidates the cause of open or closed nanotube tips based on gas pressure conditions. The combination of in-situ SEM technology and ex-situ sequential TEM analysis emerges as a robust and reliable methodology for investigating high-temperature heterogeneous reactions.

Published: July 2023

A new class of Lewis base stabilized formoxyboranes demonstrates the feasibility of catalytic transfer hydroboration. In the presence of a ruthenium catalyst, they have shown broad applicability for reducing carbonyl compounds. Various borylated alcohols are obtained in high selectivity and yields up to 99 %, tolerating several functional groups. Computational studies enabled to propose a mechanism of this transformation, revealing the role of the ruthenium catalyst and the absence of hydroborane intermediates.

Published: July 2023

Flexible metal-organic frameworks (MOFs) are highly desirable materials for gas separation but most of them become rigid when the particle size is reduced towards nanoscale. We aim to comprehend the effect of textural properties such as crystal size, its distribution and morphology on the gate-opening behaviour stimulated by adsorption of guest molecules in ZIF-7. The synthesis conditions are varied to obtain ZIF-7 batches with crystal sizes ranging between 0.05 and 15 m with various size distributions. We report for the first time a CO2-filled open pore phase of ZIF-7 at 195 K (OP2) derived from in situ powder X-ray diffraction (PXRD) data measured in parallel to CO2 physisorption. The adsorption of CO2 on ZIF-7 indicates persisting flexibility for all particle size regimes; with the crystal size, its distribution and morphology having a significant impact on both gate-opening and gate-closing pressures and slope of CO2 adsorption isotherms. In situ PXRD measurement indicated further expansion of ZIF-7 framework in presence of methanol as guest species. The capability of ZIF-7 to accommodate molecules larger than its 0.3 nm window diameter signifies the importance of intermolecular interactions to overcome the energy barrier for linker movement/gating of the framework.

Penyakit Alzheimer atau Alzheimer’ s disease (AD) merupakan salah satu penyakit neurodegeneratif yang paling umum didiagnosis pada populasi dunia, terkhusus pada wanita. Beberapa manifestasi patologi yang dapat diobservasi adalah deposisi beta-amyloid (Aβ), hiperfosforilasi protein tau, dan inflamasi yang ketiganya berperan sebagai core-pathology dari AD. Permasalahan terberat dari terapi AD saat ini adalah ketidakmampuan berbagai agen farmakologis saat ini untuk menghentikan progresivitas AD. Oleh karena itu, salah satu ikon terapi medis modern yaitu terapi sel punca atau stem cell (SC), khususnya menggunakan sel punca mesenkimal atau mesenchymal SC (MSCs) pada beberapa tahun terakhir telah dijadikan sebagai salah satu fokus studi terapi kuratif penyakit degeneratif yang selama ini hampir selalu tidak mungkin tercapai. Manuskrip tinjauan sistematis ini bertujuan untuk menjabarkan pengaruh transplantasi MSCs secara xenogenik maupun alogenik pada berbagai spesies tikus yang telah diinduksi dengan Aβ untuk mengalami kondisi AD buatan yang dilaporkan oleh berbagai penelitian orisinal pada beberapa tahun terakhir. Sebanyak 32 penelitian dijadikan sebagai referensi utama yang keseluruhannya menunjukkan perbaikan perihal manifestasi patologis seperti reduksi dari deposisi Aβ, penurunan kondisi inflamasi melalui berbagai biomarka, peningkatan aktivitas neurogenesis pada beberapa regio otak seperti hipokampus, dan efek neuroproteksi yang cukup signifikan. Pengaruh tersebut juga dapat diobservasi pada kondisi tingkah laku (behavior) tikus percobaan seperti perbaikan fungsi kognitif dan memori yang diukur berdasarkan metode observasi tertentu. Oleh karena itu, MSCs diduga memiliki potensi untuk menjadi sebuah terapi kuratif bagi AD yang selama ini tidak mampu menghentikan progresivitasnya.

Berada pada era revolusi industri 4.0 mengharuskan manusia berbasis informasi, tidak terkecuali peserta didik. Keharusan menghasilkan peserta didik yang berkarakter selalu menjadi prioritas, namun harus menyesuaikan dengan tantangan yang ada. Penggunakan internet cenderung memberikan penyimpangan pada sejumlah besar peserta didik untuk mengakses konten pornografi, tindakan bully, dan kata-kata makian pada laman media sosial karena minimnya pengawasan orang tua terhadap aktivitas digital yang dilakukan oleh anak, sehingga memicu timbulnya kejahatan cyber. Salah satu solusi yang dapat dikembangkan dalam dunia pendidikan adalah melalui kebijakan literasi digital. Tujuannya adalah bagaimana memberikan peta jalan agar kebijakan literasi digital diantara stakeholder di lingkungan sekolah dapat bersinergi dalam mengaplikasikan literasi digital untuk mengembangkan karakter peserta didik. Kajian ini menggunakan studi pustaka untuk mengurai kebijakan literasi digital dalam pengembangan karakter peserta didik. Hasil yang dapat dirumuskan bahwa pihak sekolah harus berkolaborasi antara dua elemen penting yaitu pihak keluarga dan lingkungan masyaraka untuk memberikan penguatan terhadap literasi digital dalam membentuk karakter peserta didik.

Published: July 2023

Purpose: The current analysis aimed to review the state-of-the-art about innovation and organizational culture in enterprises placed or working in South America.
 
Theoretical Framework: Innovation and organizational culture are critical concepts in management studies nowadays. In South America, in recent years, companies have had the trend to disrupt static and hierarchized organizations by allowing employees to participate actively in the organization's objectives. Moreover, flexible companies do not mean that hierarchies do not exist. Instead, it means that companies are eager to listen and accept the different points of view of the employees. Moreover, innovative companies seem to adapt rapidly to both beneficial and adverse environments. However, some firms resist changes and get revenues, but the evidence suggests that they put their sustainability in the long term.
 
Design/Methodology/Approach: In consequence, the methodological approach was the employment of the PRISM method to depurate the initial bibliographic resources from EBSCO and RENATI. EBSCO was used to analyze papers, and RENATI to review theses. Initially, there were 78 articles and 271 theses to be examined. After the PRISM depuration, it was analyzed 35 papers and theses from the period lasting from 2012 to 2021.
 
Findings: The results showed that flexible companies were more adaptative than rigid ones. Moreover, the literature suggested that flexible companies have more chances to be sustainable in the long term than other firms. Therefore, it is possible to state that innovation policies had a higher impact in flexible organizations than in rigid ones.
 
Originality/Value: The value of the study relies on the systematic review of the current literature of innovation and organizational culture in South America which is the nearest international environment for Peruvian companies.
