Evaluation of sustainable development capacity of water sources: a case study of China
Authors: Zhang Jingqi , Jiang Shaohua
Published: March 2024

The issue of water scarcity has drawn attention from all over the world. The coordination of the interaction between ecological and environmental development of water sources and socio-economic development is currently an essential issue that needs to be solved in order to safeguard the water resources environment for human survival. In this essay, we suggest a paradigm for assessing the sustainable exploitation of water resources. First, three ecological, economic, and social factors are investigated. Twenty essential evaluation indexes are then constructed using the Delphi approach, along with an index system for assessing the potential of water sources for sustainable development. The weights of each evaluation index were then determined using the combination assignment approach, which was then suggested. The coupled degree evaluation model of the capability for sustainable development of water sources was then developed. In order to confirm the viability and validity of the suggested model, the model was used to assess the Liwu River water source's capacity for sustainable growth in the context of the South-North Water Transfer in Shandong, China. It is believed that the aforementioned study would serve as a helpful resource when evaluating the capacity of water sources for sustainable development.

This study aims to develop a practical and facile one-pot synthesis of 2-
substituted quinazolines. Using a commercially available and structurally simple ruthenium(
II) complex as the catalyst to synthesize a series of quinazoline derivatives via acceptorless
dehydrogenative coupling. The mechanism of this reaction was explored by control
reaction and DFT calculation. This protocol offers access to a diverse array of quinazoline
derivatives (52 examples) in moderate to excellent yields (29%-98%). In summary, we
have developed an efficient one-pot ruthenium (II)-catalyzed ADC synthesis of quinazoline
under an air atmosphere. The reaction only produces hydrogen and water as by-products,
serving as a sustainable and atom-efficient synthetic approach.
Study on the Catecholase Activity in the Presence of a Mn(III)-based Catalyst and Base
Authors: Tripathy Rashmi Rekha , Sarkar Sohini , Jana Samaresh
Published: March 2024

Background:

This work describes the oxidation of a catechol moiety to the corresponding qui-none by using Mn(III)-based catalysts in the presence of an organic base. Two newly reported Mn(III)-Schiff base complexes were utilized for the oxidation of three different substrates, namely, 3,5-di tert-butyl catechol, 1,4-dihydroxy benzene and pyrocatechol, aerobically.

Objective:

We intended to understand the role of a base for the above-mentioned oxidation process. Also, we were interested to monitor the progress of reaction using 1H-NMR spectroscopy and to get more insight into the mechanistic path of the reaction.

Methods:

The oxidation processes were studied in open air in acetonitrile or methanol solvent. The reaction mixture containing concerned substrate, catalyst, and base were stirred in open air and 1H-NMR spectrum was recorded using the crude reaction mixture in different time intervals.

Results:

Interestingly, introduction of a base in the reaction mixture, enhanced the rate to a great extent for the first two substrates. This observation may provide an idea toward the rate determining step of the pro-cess. Notably, the third substrate, pyrocatechol, could not be oxidized by any of the two catalysts even with a base. The oxidation of 1,4-dihydroxy benzene may emphasize monodentate binding mode of the sub-strate. Each of the oxidation was monitored with the help of time dependent 1H-NMR spectroscopy.

Conclusion:

A mechanistic pathway has been proposed. The spectra obtained in different cases help to compare the efficiency of the catalysts with or without base. In the absence of the catalysts, triethylamine alone cannot complete the conversion in the stipulated time, which may establish the effectiveness of the catalysts via the base-assisted mechanism.

Published: March 2024

Background:

Congenital tracheal stenosis is defined as the narrowing of the airway lumen
due to the abnormal formation of complete tracheal cartilage rings. It may present with different
clinical pictures, depending on the range and extent of stenosis. We present two cases of congenital
tracheal stenosis, with a different range of severity and, consequently, different treatment
approaches.

Case Presentation:

We describe the case of a 3-month-old infant with breathing noise that worsened
particularly when crying and after nutrition. He presented a congenital funnel-shaped
tracheal stenosis with an associated tracheal bronchus, which was treated endoscopically with an
endobronchial stent. The second presented case is of a newborn who presented severe respiratory
distress and inspiratory stridor in the first hours of life. A congenital cylindrical tracheal stenosis
was diagnosed and it was treated surgically through slide tracheoplasty.

Discussion:

These two cases showed us that congenital tracheal stenosis can present with a very
variable clinical picture. Thus, according to clinical presentation, different treatments can be considered.

Conclusion:

We underline the importance of considering congenital tracheal stenosis in the differential
diagnosis of prolonged wheezing and recurrent airway infections.

Published: March 2024

Introduction: Infertility is presently a leading and longstanding gynaecological issue affecting approximately 15% of the couples in reproductive age group around the globe while 10-15% in Indian population. Ovulatory dysfunctions form the major cause of female infertility, out of which Anovulation accounts for 40%. Anovulation can be interpreted as Abeejotsarga or Abeejata. Panchakarma plays an important role in the management of Infertility. Thus, the present study aimed at evaluating the ovulation inducing effect of Jeevantyadi Yamaka through Matra Basti and Uttara Basti. Methodology: The study was conducted on 40 female subjects, diagnosed of anovulation with either primary or secondary infertility, fulfilling the inclusion and exclusion criteria and were randomly allocated into two groups with 20 subjects in each. But only 33 patients completed the trial with 18 patients in Group A and 15 patients in Group B. Group A received Jeevantyadi Yamaka Matra Basti while Group B were administered with Jeevantyadi Yamaka Uttara Basti for a period of three menstrual cycles. The assessment of results was done by follicular study conducted from 9th day of menstrual cycle till 20th day of every cycle for consecutive three cycles. Results: Both the groups showed significant improvement in assessment parameters. Although the number of patients were less in Group B than Group A but Ovulation was observed in 5.5% of subjects in Group A and 40% of subjects in Group B. Discussion: Jeevantyadi Yamaka Matra Basti and Uttara Basti both are equally effective in increasing the size of follicles and other assessment parameters. But in overall, Jeevantyadi Yamaka Uttara Basti was more effective in achieving Ovulation due to its local effect. As, this study was only for three months so no result was seen on Conception.
Role of Dhatvagni in disease pathogenesis
Authors: Monika Prajapat  , Ashok Kumar Sharma  , Kishori Lal Sharma
Published: March 2024

Agni is an important aspect of existence of human life. Agni is intended to be a symbol of wholesome life within the body. Its depletion poses a serious threat to life. It determines how much food should be consumed and also affects food digestion, metabolism, cell transformation and nourishment of tissues. It is crucial for determining the severity of disease and health. Agni is classified into 13 types: one Jatharagni, five Bhutagni, and seven Dhatvagni, based on its functions and site of action. The most significant is Jatharagni, which breaks down four different kinds of food into Rasa and Mala. The five Bhutagnis feed the Bhutas in the body by acting on the corresponding Bhutika part of the meal. Every Dhatu is divided into three parts by the seven Dhatvagni acting on its corresponding Dhatus. Thus, the two categories of goods that come from the full transformation process are Prasad (essence) and Kitta (excrete). The former is consumed for sustenance, whereas the latter is discarded because, if it remains in the body longer, it defiles it. Dhatu is either depleted or overproduced depending on whether the Agni rise or decrease. This shows that Agni has an autoregulatory and negative feedback system. The restoration of a well-formed Dhatu and the adjustment of Agni are necessary for disease treatment. Hence, our body’s normal physiology and pathology depends on Agni, mainly Dhatvagni.

Women represent the cornerstone of a family’s overall health. Healthy women, Healthy world embodies that women are custodians of family health; they play a critical role in maintaining the health and overall wellbeing of community. In Ayurveda word “Artava” denotes menstrual blood.  Artava is related to 2 seasons i.e., it may be due to presence of Ritukala (ovulation period) and Rajakal (menstruation period) in women. Human body is controlled by the three energies called Tridoshas - Vata, Pitta and Kapha which are characterized under seven Dhatus. These Dhatus have Updhatus also. Artava (menstrual blood) is one of the Updhatus of Rasa Dhatu.[1] The specific characteristics of menstrual blood with its physiological and pathological variation described in Ayurveda classics as Shudhartava and Artavdhusti respectively help in identifying the hormonal status of women. Shudhartava plays crucial role in maintaining women’s healthy reproductive life. When Artava is not quite same as highlights of Shudhartava mentioned in classics then there may be Artavdushti or menstrual abnormalities like dysmenorrhoea, menorrhagia, amenorrhoea etc uterine disorders like endometriosis, adenomyosis, uterine fibroid, etc which may be cause of infertility. Ayurveda classics explains about colour, texture, specific smell, amount and other associated features like type of pain in various Artavdushti. So, only by observing menstrual blood variation we can find out the disease associated with it. Thus, study of Artava and Artavdhusti plays a very significant role in diagnosis of pathological disorders related with female reproductive system.

A clinical assessment of Dhatu with Nadi Parikshan
Authors: Aishwarya Pandey  , Ashok Kumar Sharma
Published: March 2024

According to Ayurveda, the human body's physiology revolves around the balance of the Dosha, Dhatu, and Mala.[1] Dhatu acts as both structural and functional components of body. It gives strength to the body and performs many functions including nourishment of body, circulation of biomaterials, holding up the organs, reproduction and maintenance of body frame, etc. In Ayurveda the method of diagnosis and reporting of various clinical parameters has been mentioned under pulse diagnosis. It is a very important diagnostic tool referred to as the Ashtvidhpariksha. The only non-invasive diagnostic approach that can identify the state of Dosha is the Ayurvedic pulse diagnosis; however, it takes a lot of regular practice.
Ayurvedic approach to Embryogenesis: Exploring Fetal Development
Authors: Varsha  , Himanshu Chouhan
Published: March 2024

Background: Embryology in Ayurveda is the study of embryonic and fetal development using Ayurvedic principles. Ayurveda describes the conception process, fetal development, and the effect of Doshas (biological energies) on the fetus's growth and health. Ayurvedic embryology emphasizes the mother's health and well-being during pregnancy, as well as the effect of the father's Doshas on the child's genetic makeup. It also includes prenatal care guidelines, such as diet, lifestyle, and herbal remedies, to help the fetus develop normally. Aims: This review applies Ayurvedic concepts of Grabhasharir to embryology, analyzing the genesis of progeny using modern scientific knowledge. Materials and Methods: Brihattrayee along with other relevant literature were reviewed to identify the hidden core of embryology described in chapters about Garbhasharir. Results: The Ayurvedic essence outlines two types of processes in progeny genesis: dependent and independent, with dependent processes modifying and independent processes unaffected by parental efforts. Conclusion: Even though the embryology concepts outlined in Ayurveda extend back millennia, they are still relevant in today's scientific world when properly interpreted.

WHO defines stroke as a "neurological deficit of cerebrovascular cause that persists beyond 24 hours or is interrupted by death within 24 hours". There are two main types of stroke: ischemic, due to lack of blood flow, and hemorrhagic, due to bleeding. Both cause parts of the brain to stop functioning properly. Stroke is a major global public health problem. According to the Global Burden of Diseases (GBD) study in 1990, stroke was the second leading cause of death worldwide. Subsequent efforts to update the GBD study reported nearly 5.87 million stroke deaths globally in 2010.With the rising proportion of mortality, stroke still remains the second leading cause of death worldwide. The present study is a diagnosed case of ruptured right DACA aneurysm and unruptured right MCA M1 segment aneurysm and ICD (International classification of diseases) classification as Subarchnoid hemorrhage from middle cerebral artery. The patient presented with symptoms of loss of strength and weakness in left upper & lower extremity with stiffness. The Ayurvedic diagnosis of Vama Pakshaghata was done and managed with Dhanyamla Seka, Abhyanga, Shastika Shali Pinda Sweda, Dhara and Matrabasti. Two assessments were made before and after treatment using the National Institute of Health Stroke Scale (NIH-SS). The patient got significant improvement in the signs and symptoms and improvement in movements within 45 days. The results were remarkably encouraging.

Due to advent of commercialization longer shelf-life becomes the need of the hour for various pharmaceutical products, especially for the preparation of Kwatha Kalpana (Decoction). The shelf-life of Kwatha is 1 Prahara (3 hours). According to Acharya Sharangadhara it is considered as Sadhyo-sevana. Panchavidha Kashaya Kalpana are considered as basic pharmaceutical preparation and the most important form of Kalpana. But the preparation of Kwatha is not possible all the times as the shelf life of Kwatha is short and makes it impossible to market it as soon as it is prepared. Therefore, there is need to find different ways to preserve the Kwatha for longer duration for their easier usage and transportation. This present study is carried out mainly in 3 stages, that is, pharmaceutical study, analytical study and microbiological study. In pharmaceutical study, the preparation of Baladi Kwatha was carried out as per the classical reference of Shamana Kashaya and they were added with different ratios of preservatives (SB-0.1%, SB-0.2%, SB-0.2% + MP-0.05% + PP-0.05%, SB-0.48% + MP-0.1% + PP-0.1%). No much changes were noted in analytical studies.  Preservatives like, sodium benzoate, in permitted amounts could only preserve acidic Kwatha for a shorter period. Hence, marketing Baladi Kwatha with sodium benzoate cannot be properly stabilized by 0.1% & was observed that at least 0.2% is required to preserve the Kwatha for 60 days free from microbial contamination. It was observed that as per the permissible limit, the preservatives when used in combination of sodium benzoate 0.2%, methyl paraben 0.05%, propyl paraben 0.05%, has passed the shelf-life for 3 months.

Analysis of blockchain introduction strategies in maritime business with game theory modelling
Authors: Rusinov I. A. , Zatolokina M. Y.
Published: March 2024

In the last years the blockchain technology has attracted the focus of many companies in maritime business, due to its potential to make a revolution in this field. This technology became especially important in supply chains, where it offers the possibility to increase the transportation effectiveness. It is shown that currently there is no instrument to analyze the strategies on blockchain technology introduction in maritime shipping. In order to solve this problem, it is suggested to use game theory models, which allows you to simulate the relationships among maritime shipping participants. In order to create a model of such type, the description of main participants is represented in the paper and the main schemes of their interaction are analyzed. The structured schemes of the participants introduction, during the organization of maritime shipping in a traditional form and with the utilization of blockchain are suggested in the paper. The structure of basic game theory model of maritime shipping is shown. In order to show the possibilities of the analysis using the proposed model four experiments are considered. The first one is the traditional form of participants interaction. The second one is the interaction of participants fully through the blockchain. The third one is the change of attitude to blockchain depending on economic efficiency. The fourth one is the gradual introduction of blockchain technology. The results show the change of economical effectiveness of business participants in different cases. It is shown in the paper that the introduction of blockchain allows to speed up a company cash-flow, which makes the business management much easier. It is also proved that the suggested model must be improved with introduction of new conditions and motives of the participants.
Methodology for planning transportation and containerized cargo unloading in off-port conditions
Authors: Gorenkova V. S.
Published: March 2024

A methodology for planning the transportation and unloading of containerized cargo in off-port conditions, aimed at achieving the most labor-efficient result is presented in the paper. The effectiveness of using maritime transport facilities for transportation largely depends on the availability and technical condition of ports and port facilities. The study of ways to prepare an unequipped seashore for the organization of temporary transshipment points is of urgent importance due to the constant need to carry out supply transportation to Arctic destinations. In the specific conditions of the Russian Federation Arctic zone, a special transportation subsystem is formed by regular northern (expeditionary) delivery. Despite a significant amount of scientific research in the field of transport support, the specific tasks of scientific substantiation of transport and technological transportation systems in off-port conditions are currently insufficiently investigated. To solve the problem under consideration, it is necessary to develop new technical and technological solutions. Modern conditions for the cargo transportation implementation generally involve the use of two technological schemes for transporting containerized cargo units from the vessel hold to the coastal zone at each of the destinations by moving each individual unit using a pontoon or helicopter. To improve the transport and technological transportation system efficiency in off-port conditions, in addition to the existing ones, an alternative scheme based on the use of self-disassembling pontoons (lighters) when unloading cargo on an unequipped coast is proposed. The methodology for planning the transportation and unloading of containerized cargo in off-port conditions is based on the fact that the particular object of research is technological schemes for transporting certain volumes of batches of containerized cargo units of various categories, implemented within a given destination. The initial data and design characteristics used in the methodology implementation, as well as the structure of the developed methodology described in the form of a flowchart are presented in the paper. The methodology calculates a complex preference indicator for each technological scheme under consideration. The considered technique allows us to determine the most preferred technological scheme from a set of alternative schemes.
Hydroabrasive wear of jet pump nozzles
Authors: Tsvetkov Yu. N. , Petrov V. A. , Ivko I. Ye.
Published: March 2024

The measurements of hydroabrasive wear of the jet pumps nozzles, used on dredges operating on transferring pulp, are carried out. The measurement result is compared with the result of modelling the flow in the pump suction chamber near the nozzles. The modelling is carried out using the Fluent program complex as a part of the Ansys program; the pure water is being modelled in the suction pipe. This assumption is made taking into account that pulp contains approximately 10 percent by volume of sand, therefore the trajectories of sand particles movement coincide with the streamlines of water. The results of modeling have shown, that the angle of attack on the surface of nozzle nose part nearest to the pulpline outlet is close to zero, whereas the angles of attack on the surface of the nozzle nose part furthest from the pipeline outlet differ considerably from the zero and range from 20 to 50 degrees, that is the values at which the hydroabrasive wear increases severalfold compared to the angles close to zero. The results of modelling are confirmed by the examination of the worn nozzles. It is turned out that the nose part of the nozzles wears out along a circle unevenly, the part furthest from the pipeline outlet wears at higher rate, that leads to the bevel of the plane of the nozzle nose opening, the bevel angle reaches 20–25 degrees. The microhardness values of the nose part of the worn nozzle are also in agreement with the results of modelling. The measurements have shown, that the microhardness of the nose part of the worn nozzle is uneven along a circle, and the microhardness of the most worn side of the nozzle nose is least. This fact indicates that the different zones of the surface of the nozzle nose part differ from each other by the rigidity of stress state scheme in hydroabrasive attack. It can be used later in choosing the regime of laboratory tests on hydroabrasive wear.

Published: March 2024

This mini-compilation study included the chemical structure, mechanical, thermal, and dimensional properties of silk fiber, its production process, pre-treatment, and biomedical applications from various experimental studies, which are compiled and summarized. The silk fiber should have a degumming process before using biomedical applications. The 25% concentration for Na2CO3 in ethanol solution (80%) as a coagulant chemical with a salt such as LiB2 (9 M) at a temperature of 98°C for 45 minutes at pH between 6 and 7 should be applied for the degumming process of silk fiber. It has some biomedical applications such as artificial veins and surgical sutures. Its biomedical applications can be studied experimentally by changing manufacturing processes and their process parameters in the future.

Background

Peer specialists are hired, trained, and accredited to share their lived experience of psychiatric illness to support other similar individuals through the recovery process. There are limited data on the role of peer specialists in suicide prevention, including their role in intervention development.

Objective

To better understand peer specialists within the Veterans Health Administration (VHA), we followed partnership community engagement and a formative research approach to intervention development to (1) identify barriers, facilitators, and perceptions of VHA peer specialists delivering a suicide prevention service and (2) develop and refine an intervention curriculum based on an evidence-informed preliminary intervention framework for veterans with serious mental illness (SMI).

Methods

Following the community engagement approach, VHA local and national peer support and mental health leaders, veterans with SMI, and veteran peer specialists met to develop a preliminary intervention framework. Next, VHA peer specialist advisors (n=5) and scientific advisors (n=6) participated in respective advisory boards and met every 2-4 months for more than 18 months via videoconferencing to address study objectives. The process used was a reflexive thematic analysis after each advisory board meeting.

Results

The themes discussed included (1) the desire for suicide prevention training for peer specialists, (2) determining the role of VHA peer specialists in suicide prevention, (3) integration of recovery themes in suicide prevention, and (4) difficulties using safety plans during a crisis. There were no discrepancies in thematic content between advisory boards. Advisor input led to the development of Suicide Prevention by Peers Offering Recovery Tactics (SUPPORT). SUPPORT includes training in general suicide prevention and a peer specialist–delivered intervention for veterans with SMI at an increased suicide risk. This training aims to increase the competence and confidence of peer specialists in suicide prevention and the intervention supports veterans with SMI at an increased suicide risk through their recovery process.

Conclusions

This paper intends to document the procedures taken in suicide prevention intervention development, specifically those led by peer specialists, and to be a source for future research developing and evaluating similar interventions.
