Published: August 2023

Purpose

The aim of this study was to evaluate the capillary vessel density (CVD) and the flow of superficial and deep capillary plexuses (SCP and DCP) using optical coherence tomography angiography (OCTA) after vitrectomy for rhegmatogenous retinal detachment (RRD) and to correlate these changes with the visual outcome.

Patients and methods

This is a prospective interventional study that was conducted on 17 eyes with macula-off RRD. All patients underwent 23-G vitrectomy with silicone oil (SO) injection. OCTA was performed 1 month after SO removal. The outcome measures included the CVD, SCP arcade disruption, capillary dropout, SCP and DCP disorganization, and best corrected visual acuity (BCVA).

Results

There was a statistically significantly less density of the mean DCP (40.82±6.87%, P=0.03), and the mean SCP (38.95±6.75%, P=0.007) in the operated eye compared to the fellow eye. The central foveal thickness (CFT) was statistically significantly higher in the operated eye (309.06±92.12 μm) compared to the fellow eye (242.29±25.48 μm), (P=0.019). The SCP capillary arcade disruption was statistically significantly more frequent in the operated eyes (12=70.6%) especially in the eyes with subretinal fluid (SRF) (P=0.049) and those with cystoid spaces (P=0.049).

Conclusion

The CVD, excluding the fovea, was significantly worse in the operated eyes. The SCP arcade disruption, capillary dropout, and SCP and DCP disorganization were detected in most patients following RRD repair, but with no significant correlation with BCVA.

Published: August 2023

Background:

To investigate the incidence of falls in elderly in nursing homes and to determine the differences in confidence indexes of daily living in the Activities-Specific Balance Confidence Scale (ABC) in elderly fallers or nonfallers.

Methods:

We conducted a perspective study with elderly (ages >75 years old) from January 1, 2018, to December 31, 2020, living in community nursing homes in Tongzhou district, Beijing. All the participants were able to walk independently, had not experienced any fall episodes, were capable of following commands, and they sufficiently cooperated with the process of the examination. A face-to-face visit or telephone interview was conducted with participants on a regular basis for 12 months. The falling incidence and the differences of ABC scale confidence indexes between fallers and nonfallers were investigated.

Results:

This study included 87 older adults (67 nonfall participants and 20 fall participants). Falls occurred at a rate of 23 per 100 people per year. The ABC scale index of the faller group was 37%, which indicated very low balance confidence and a high risk of falling. The ABC scale index of the nonfaller group was 80%, which indicated normal balance confidence and no risk of falling. There were significant differences in ABC scale indexes between the faller and nonfaller groups (37% vs. 80%, P = 0.005). There were significant differences in activities such as walking around the house, climbing up and down stairs, picking up slippers from floor, reaching on tiptoes, standing on a chair to reach, walking outside to a nearby car, getting in/out of a car, walking across a parking lot, walking up and down a ramp, walking in a crowded mall between two groups of people, walking in a crowd (risk of bumping into other people), going up an escalator without rail assistance, and walking on an icy sidewalk between the two groups (P < 0.05).

Conclusion:

Nursing homes have a high rate of falls among older adults. The ABC scale can assess balance confidence and the risk of falling in older adults. To reduce or prevent falls, health-care professionals should screen those who are at high risk of falling and enroll them in a fall prevention program.

Published: August 2023

Objective:

This study aimed to determine the risk factors associated with short-term neurological decline in acute ischemic stroke patients with large vessel occlusion (LVO) who have undergone successful endovascular recanalization through mechanical thrombectomy.

Subjects and Methods:

We included 168 LVO patients who had successful recanalization in this study. We collected the patients' demographic data and related disease test results. We noted the National Institutes of Health Stroke Scale (NIHSS) scores at the onset and on the 7th day postonset. After comparing the NIHSS scores at these two time points, we analyzed the correlation between the collected data and the NIHSS scores. We selected the logistic regression model variables based on the correlation significance. We included gender, age, diastolic blood pressure, glycosylated hemoglobin, urea nitrogen, hemoglobin, neutrophil-to-lymphocyte ratio (NLR), low-density lipoprotein, and total protein in a logistic regression model. We used the receiver operating characteristic (ROC) curve to evaluate the predictive power of NLR for deterioration.

Results:

Mechanical thrombectomy significantly lowered the median NIHSS score of LVO patients on the 7th day of onset, while a subset of patients experienced an increased NIHSS score. Correlation analysis revealed significant correlations between the NIHSS score at onset and diastolic pressure, white blood cell count, neutrophil count, creatinine, and urea nitrogen. On the 7th day postonset, NIHSS scores showed significant correlations with glycosylated hemoglobin, white blood cell count, neutrophil count, NLR, red blood cell count, hemoglobin, and urea nitrogen. Logistic regression analysis further revealed that patients with higher NLR are at significantly increased risk of short-term neurological decline. ROC analysis indicated that a higher NLR can serve as a diagnostic marker for potential adverse outcomes of mechanical thrombectomy.

Conclusion:

While mechanical thrombectomy substantially improves neurological deficits in LVO patients, some patients still experience deterioration. Higher NLR at stroke onset is associated with short-term neurological function decline in acute LVO patients postsuccessful recanalization.

Published: August 2023

Introduction:

High fluoride concentration in groundwater can result in endemic fluorosis and is a major public health problem in India.

Aim:

To know the association between prevalence of dental fluorosis and dental caries and fluoride level in the water in urban Vadodara.

Methodology:

An analytical ecological cross-sectional study was conducted in 4 zones of Vadodara district. Thirty-eight water samples were sent to Gujarat Ecology Society in Vadodara for chemical analysis to test fluoride levels. The data collection was made by house-to-house visit twice during the study involving 2,609 participant interviews. These participants included 449 children belonging to the age group of <15 years. Examination for dental fluorosis and dental caries using Dean's criteria was done. Chi-Square and Mental Hensel Chi-Square were applied for statistical analysis.

Results:

The prevalence of dental fluorosis was 17.36% in high-fluoride areas and 22.46% in normal-fluoride areas among children (<15 years of age). There was no statistically significant association in dental fluorosis between high-fluoride areas and normal-fluoride areas (P = 0.2533). The prevalence of dental caries was 29.26% in high-fluoride areas and 75.36% in normal-fluoride areas. There was a statistically significant association in dental caries between high-fluoride areas and normal-fluoride areas (P ≤ 0.0001).

Conclusions:

The risk of dental caries was clearly higher in the areas showing normal-fluoride content compared to places with high fluoride levels in drinking water. The risk of dental fluorosis was higher in area with high-fluoride level but the difference was not statistically significant.

Published: August 2023

Objective:

This study aimed at observing the prognostic factors for Graves' disease (GD) recurrence after treatment with antithyroid drugs.

Patients and Methods:

Clinical data for 247 patients with primary GD hyperthyroidism diagnosed in the endocrinology department of our hospital between March 2014 and February 2017 were collected. Age, sex, thyroid size, thyroid hormone levels, thyrotropin receptor antibody (TRAb), thyroglobulin antibody, thyroid peroxidase antibody, urinary iodine, and other prognostic factors before and after treatment were analyzed and compared.

Results:

After ATD treatment, 151 cases were in remission and 96 cases were not. The mean age at diagnosis was 37.3 ± 14.0 years in the remission group and 31.2 ± 12.2 years in the nonremission group (P = 0.032). The levels of free triiodothyronine (FT3) in the nonremission group and remission group were 25.7 ± 8.4 and 18.3 ± 9.1 pmol/L, respectively. The proportion of patients with goiter and thyroid-associated orbitopathy was higher in the nonremission group than the remission group. Similarly, both the FT3/FT4 ratio (4.63 ± 1.08 and 3.72 ± 0.69, P= 0.020) and TRAb level (27.4 ± 10.7% and 18.1 ± 9.8%, P= 0.001) significantly increased. Logistic regression analysis indicated that high thyroid volume (odds ratio [OR] =9.647, P= 0.003), high free T3/free T4 ratio (OR = 1.541, P= 0.019), and TRAb level (OR = 1.317, P= 0.002) were independent factors influencing drug treatment failure and were associated with poor prognosis. After drug withdrawal, patients with distinctly enlarged thyroid glands, thyroid-associated eye disease, and low serum thyroid-stimulating hormone (sTSH) levels were higher in the nonremission group than in the remission group.

Conclusion:

GD patients with goiter, high TRAb level and high FT3/FT4 ratio had poor poor response to drugs. The recurrence rate was high in patients with thyroid-related eye disease, and sTSH delayed recovery.

Authors: Shrivastava Saurabh RamBihariLal , Shrivastava Prateek Saurabh
Published: August 2023

The problem of burns has been recognized as one of the major global public health concerns primarily due to the millions of people succumbing to the burn-related complications each year. In addition, nonfatal burns are a predominant cause of morbidity, disability, impaired quality of life, and prolonged hospitalization, which are commonly associated with secondary infections. Acknowledging the fact that the developed nations have made remarkable progress in reducing the death rates through the strengthening of prevention strategies and improvement in medical care to the victims, it is very much possible to minimize the incidence of burns and the associated complications. To conclude, there is an immense need to have a multifaceted approach to minimize the incidence of burns and upgrade the quality of care offered to the victims, especially in low- and middle-income nations. Furthermore, sustained efforts are required to reduce the rates of disability and burn attributed death rates.

Authors: Shrivastava Saurabh RamBihariLal , Shrivastava Prateek Saurabh
Published: August 2023

The human immunodeficiency virus (HIV) infection has been regarded as a global public health concern. In the global mission to minimize the existing gap on the diagnostic front, a number of strategies to promote HIV testing have been encouraged in heterogeneous settings. Detection of HIV infection using self-testing kits has emerged as an important approach to ascertain the identification of new cases and for connecting the affected people with the health-care delivery system. It is quite an alarming fact that despite HIV is a major public health problem in India, we to date have no policy on the promotion of self-testing. The findings of a recently released report in India revealed that self-testing was found to be acceptable to vulnerable population groups and their partners. To conclude, acknowledging the merits that have been linked with self-testing and considering the encouraging results obtained in Indian settings, it is the need of the hour that policymakers draft the much-awaited policy on the promotion of HIV self-testing in the nation and promote it.

n this paper, we investigate the geometric properties of quasi-trees and prove some equivalent criteria. We give a general construction of a tree that approximates the ends of a geodesic space, and use this to prove that every quasi-tree is

(1,C)

-quasi-isometric to a simplicial tree. As a consequence, we show that Gromov's tree approximation lemma for hyperbolic spaces (1987) can be improved in the case of quasi-trees to give a uniform approximation for any set of points, independent of cardinality. From this we show that having uniform tree approximation for finite subsets is equivalent to being able to uniformly approximate the entire space by a tree. As another consequence, we note that the boundary of a quasi-tree is isometric to the boundary of its approximating tree under a certain choice of visual metric, and that this gives a natural extension of the standard metric on the boundary of a tree.

Authors: ARSLAN Eylem , ASLAN Cumhur
Published: August 2023

Sosyal bilimler literatüründe sembol, siyaset ve ideoloji birbiriyle oldukça yakından ilişkili kavramlardır. Sembolik siyaset kavramı ise sembollerin siyasi düşünce ve temsilcileri tarafından ideolojik bir araç olarak kullanılması anlamına gelir. Bu bağlamda sembolik siyaset; sembol, siyaset ve ideoloji arasındaki ilişkiyi anlamaya olanak sağlar. Türk sembolik siyaseti özelinde ise Ayasofya, içerdiği farklı sembolik anlamlar ve ideolojik kavramlar neticesinde geçmişten günümüze dek bir araç olagelmiştir. Hem Doğu hem de Batı kültürüne ait olan Ayasofya, Türk siyasi ideolojilerindeki Doğu-Batı ikiliğinin somutlaştığı başlıca yapılardandır. Bu nedenle aidiyet duygusu, üstünlük ve kutuplaşma için de elverişli bir semboldür. Özellikle İslamcı ve milliyetçi-muhafazakâr bakış açısında Ayasofya Cami sembolü sıklıkla kullanılır. Bu sembolü kullanan önemli isimlerden biri ise İslamcı düşünür ve yazar Necip Fazıl Kısakürek’tir. Kısakürek’in Ayasofya ile ilgili söylemleri, sembollerin siyasi ve ideolojik özelliklerini içerir. Dolayısıyla Ayasofya’nın sembolik siyasetteki rolünü ortaya koymak amacıyla çalışmamızda Necip Fazıl Kısakürek’in Ayasofya Hitabesi’ndeki söylemlerine eleştirel söylem çözümlemesi yapılmıştır. Böylelikle ideolojilerin meşrulaştırılmasında ve iktidar/güç ile hegemonyanın kurulmasında Ayasofya’nın nasıl araçsallaştırıldığı açıklanmaya çalışılmıştır.

Objective: Although the MLCs who are admitted to the Pediatric Intensive Care Unit establish a crucial health burden, the risk factors, epidemiologic data and clinical signs of such cases have not been documented in a regular and comprehensive way.

Methods: A retrospective patient review was made. This study was conducted in the PICU of Bursa Yuksek Ihtisas Training and Research Hospital, Bursa, Turkey, between 01 January 2017 and 01 January 2022. This study enrolled 31 males (35.4%) and 17 females (64.6%) aged 4.7 ±4.1 years. We classified MLCs into nine groups as Foreign Body Aspiration (FBA), Blunt Trauma (BT), Asphyxia (ASP), Firearm Injury (FI), Sharp and Penetrating Object Injury (SPOI), Electric Injury (EI), Sports-Related Injury (SRI), Animal Bite Injury (ABI), Home Accident (HA).

Results: FBA is the dominant type of MCL of this study (29,1%). The average hospital stay of FBA cases in the ward was 3 (1-11) days; in PICU was 2 (1-8) days. The average hospital stay of BT cases in the ward was 4 (1-12) days; in PICU was 3 (1-10) days. The average hospital stay of ASP cases in the ward was 2 (1-6) days; in PICU was 2 (1-7) days. 29,1 percent of the patients (n=14) required the surgery. In our study, we calculated that the mean voice of treatment of a case is 5744 ₺ (around US$308,57). The most significant proportion of the MLCs was caused by FBA (n=14, 43%), followed by BT (n=9, 18%) and ASP (n=8, 16%).

Conclusion: All parties which want to make decrease in the number of the MLCs, should draw attention to prevention efforts
Notice of a new Crataegus ‘Kokhno’ and +Crataegomespilus
Authors: Mezhenskyi Volodymyr , Klymenko Yurii
Published: August 2023

Crataegus (+Crataegomespilus) ‘Kokhno’ is a new graft chimera originated from the junction where Crataegus germanica (= Mespilus germanica) scion was top-grafted onto a stock Crataegus sp. In 1993, in the arboretum of one of the forestry-division offices in the Volhynia region, Vladyslav Oleshko found a putative hybrid between hawthorn and medlar, which was named in honor of well-known Ukrainian dendrologist Mykola Kokhno. He believed this plant was the result of a crossing between Mespilus germanica and Crataegus ucrainica because it was characterized by heterophylly having a mixture of both medlar and hawthorn leaves. The flowers of this plant are not solitary but placed in corymbs. The fruits are not aligned in size and range from 0.5–5.0 cm in diameter. The study of this hawthorn-medlar in the dendrological collection of the M.M. Hryshko National Botanical Garden (Kyiv, Ukraine) led to the conclusion that it is a graft chimera, not a hawthorn-medlar sexual hybrid. This hawthorn-medlar cultivar is morphologically similar to medlar but differs in the arrangement of flowers and fruits. The fruits typical for varietal medlar develop from solitary flowers, whereas atypical small fruits are located in groups. Both types of fruits have no germs in the stones. The cultivar ‘Kokhno’ is adapted to the Forest-Steppe of Ukraine and performs well as an ornamental and fruit plant. An outline of the history and nomenclature of graft hybrids (chimeras) between Crataegus and Mespilus is given.

Authors: KOÇASLAN İlhan , ÜSER Yavuz , KÖSE Utku
Published: August 2023

BLDC (Brushless DC) motors have advantages over asynchronous motors and dc motors in various aspects. Particularly in electric bicycles and flying cars, BLDC motors are utilized widely. Electric bicycles and flying cars are becoming increasingly popular, and as a result, the significance of BLDC motors and their cost-effective and efficient utilization has been growing rapidly. PID (Proportional Integral Derivative) controllers are generally used in motor control because they are cheap and perform well. Many methods have been used to adjust PID parameters. Although methods such as Ziegler-Nichols, Cohen-Coon etc. are widely used, there are also new methods such as optimization algorithms PSO (Particle Swarm Optimization), Whale Optimization Technique, Gray Wolf Optimization technique etc. The hybrid method: HPSOGWO (Hybrid Algorithm of Particle Swarm Optimization and Grey Wolf Optimizer) is a combination of PSO and GWO (Grey Wolf Optimizer) techniques, and it can be used for tuning PID parameters. As associated with this, the aim of this study is to show the superiority of HPSOGWO algorithm in optimizing the PID parameters. In the content of this study, the essentials regarding the optimization background, and details of the BLDC motor modeling was explained first. After that, the methodology of the hybrid solution was expressed and then the application phase was explained in detail, by including the results generally. In the context of the intelligent optimization approach of this study, the results were obtained in the MATLAB Simulink environment. The application of the used solution method revealed its superiority over the study conducted solely with GWO in various parameters.

This study aims to determine the appropriate application time interval of rabbit urine POC to support optimal growth and production of mustard greens. This study used an experimental method designed using a completely randomized design (CRD) with 4 treatments, including W0 (control), W1 (treated with 60 ml/L rabbit urine every 1 week), W2 (treated with 60 ml of rabbit urine /L every 2 weeks), and W3 (treated with 60 ml/L rabbit urine fertilizer every 3 weeks). Variables observed in this study included growth variables consisting of plant height, number of leaves, leaf width, and leaf length at 1 – 6 WAP, as well as production variables in the form of wet stover weight per plant (grams) and plant consumption weight (grams) at 6 WAP. The data obtained were analyzed by ANOVA and if it had a significant effect then continued by the Tukey test at the 95% level of confidence. The results of the study showed that the time interval treatment for application of POC rabbit urine only had a significant effect on the variable number of leaves, leaf length, and leaf width at 6 WAP and plant consumption weight. The time interval application of 2 weeks (W2) rabbit urine POC tend to give better results than other time interval treatments in almost all observation variables.

This study used a Factorial Completely Randomized Design (CRD). The first factor was planting media (M) which consisted of three categories, namely: topsoil (M0), mixed soil and goat manure with a ratio of 2:1 (M1), soil and chicken manure with a ratio 2:1 (M2). The second factor was foliar fertilizer (P), which consisted of no foliar fertilizer (P0) and application of gandasil D fertilizer (P1). The results showed that the M0 treatment had a significant effect on the weight of the pods and the fresh weight of the plant, but did not have a significant effect on the plant height, the number of branches and the flowering time. The application of gandasil D has no significant effect on all observed variables. The combination of media type and gandasil D had a significant effect on plant height at 3 WAP in the M2P1 treatment, the number of pods in the M2P1 treatment, the weight of the pods planted in the M0P1, M0P0 treatments, and the fresh pod weight in the M0P0, M2P1, M1P0 treatments, but had no significant effect on plant height, number of branches and flowering time. In the observed variables of pod weight and fresh pod weight, the application of animal manure gave a good response to the availability of nutrients that can be absorbed by plants.

Syzygium aromaticum seed from the family of Myrtaceae is a highly priced natural spice used in preparation of food which have been acclaimed and reported by previous researchers to have anticancer activities potentials. Due to the rising burden of cancer worldwide its severity and fatality coupled with side effects of synthetic drugs calls for an alternative treatment solution. Hence the current research studied the phytocompounds from the seed by extracting and screening the compounds using solvent maceration method and gas chromatography coupled to mass selective detector respectively to extract, identify and quantify the component phytochemicals present in the seed. Site directed multi-ligand docking of the identified compounds was performance on progesterone receptor protein responsible for breast cancer development using the compounds from GCMS results and compared with four standard breast cancer drugs by molecular docking method. The result showed that the alpha cubebene (-7 kcal/mol), Velerena -4, 7- (II) diene (-7.1 kcal/mol), caryophyllene (-7.4 kcal/mol), caryophyllene oxide (-7.4 kcal/mol), dibutyl phthalate have binding affinity close to the standard breast cancer drugs Abemaciclib (-8.3), Anastrozole (-7.2 kcal/mol) and Paclitaxel (-8.8 kcal/mol) and they have better binding affinity than the drug Cyclophasphamide (-5.6 kcal/mol). The result also revealed that some compounds from the GC-MS were found to have a binding affinity closer tothat of thecocrystallized ligand (-10.7 kcal/mol). Other compounds from clove seed showed favourable docking scores in comparison with the drugs as many of the compounds have docking scores of more than (-6 kcal/mol) suggesting that the compounds have anti breast cancer activities since their amino acids showed hydrogen bonding corresponding to that on the binding site

Acts of terrorism targeting Very Very Important Person (VVIP) have occurred several times in Indonesia. This shows that VVIP is one of the targets of terrorist attacks. So that the evaluation of the VVIP security system is mandatory, so that VVIP  do not become victims of terrorist attacks again. The human factor, namely the mistakes of VVIP security officers, became the dominant factor in the success of terrorist attacks on VVIP. Strict sanctions against security officers who violate applicable rules need to be implemented so that other security officers do not repeat them. The implementation of a strict VVIP security system SOP is a must so that no more terrorist attacks against VVIP occur. In routine activity theory, a capable guard system can prevent a person from becoming a target for crime (terrorism).
The Influence of the Family Environment on Student Learning Outcomes in Class IV Social Studies Content di SDN 38 Ampenan
Authors: Jumiarti Jumiarti
Published: August 2023

The family environment greatly influences students' success in achieving good learning outcomes. This is reinforced by the theory in Djaali's book; Family situations (father, mother, siblings, younger siblings, older siblings, and extended family) have a significant impact on a child's success within the family. Parental education, economic status, home environment, the percentage of parental relationships, words, and parental guidance all influence a child's learning achievements. This study aims to determine the influence of the family environment on student learning outcomes in the Social Studies subject for fourth-grade students at SDN 38 Ampenan. This research falls under the category of population research and is Expost Facto in nature. The study was conducted at SDN 38 Ampenan in fourth-grade classes, consisting of parallel classes IV/A and IV/B, during the academic year 2022/2023. The data collection instrument used was a family environment questionnaire and data on student test scores in the Social Studies subject. The family environment indicators used include parenting styles, family member relationships, home atmosphere, family economic conditions, and parental understanding. The data analysis techniques employed include descriptive statistical tests, tests for homogeneity, normality, and hypothesis testing. Hypothesis testing uses simple linear regression. The research results show that the significance value obtained is less than 0.005, and the calculated t-value is greater than the tabulated t-value. This indicates that the null hypothesis (Ho) is rejected, and the alternative hypothesis (Ha) is accepted, suggesting a significant influence of the family environment on student learning outcomes in the Social Studies subject at SDN 38 Ampenan.

Unconventional mining (IT) practices are not foreign to the people of Bangka Belitung, including in Penagan Village. IT practices which are also carried out at sea certainly have an effect on the coastal fishing communities in Penagan Village. The dominant change is seen in the social and economic dynamics of the Penagan Village community. Social dynamics can be subdivided into aspects of education, health, and government policy. Meanwhile, economic dynamics can be further grouped into aspects of capital, access to and use of fishing technology, fishermen's income, and fishermen's lifestyle. In this study, we found IT to have a number of positive and negative impacts. However, the negative impact turned out to be more dominating for the coastal fishing community of Penagan Village.

NEW CONCEPT OF THE MAIN PART OF MULTICHARGED IONS LINEAR ACCELERATOR ON THE COMBINED RF FOCUSING BASIS
Authors: Tishkin S.S. , Dyachenko O.F.
Published: August 2023

A new concept of the main part of multicharged ions linear accelerator (MILAC) NSC KIPT on the combined RF focusing (CRFF) basis is proposed. In CRFF acceleration and focusing of the charged particles occurs at the expense of the same accelerating field. Absence of an external focusing field sources a design and operation of the accelerator main part considerably simplifies. The construction principle of accelerating&focusing channels with
CRFF is considered. The mathematical modeling findings of a beam dynamics for particles with mass-to-charge ratio of A/q=5 in the energies range of 1…9.2 МeV/u are resulted. Realization of this focusing method on a basis of an interdigital H type accelerating structure is proposed.

The study of SNF reprocessing is impossible without obtaining and studying a multicomponent, low-energy and complex ion beam of an “umbrella” shape. The beam is obtained from a plasma flow created in a plasma source (PS) with a magnetic field of about 3 T, flowing along the axis into a weak magnetic field, at a level of 0.1…0.5 T. At the same time, its density decreases, and the entire energy of the plasma is converted into a jet directed along the axis. To randomize the particles of the jet plasma, a reflecting magnetic field is further placed on the axis. Without changing direction, the plasma flows in a hollow magnetic force tube around a solenoid with a reverse magnetic field. In this region, ions are drawn out in the radial direction towards the annular hole of the “pocket”. The target
ions, M (230-277) follow umbrella trajectories and, being neutralized, are deposited in the “pocket” on the inner walls, the remaining ~ 3% are scattered and remain on the walls of the separator.
COSMIC RAY SOURCE AND SOLAR ENERGETIC PARTICLES

Published: August 2023

The acceleration of particles to the high energy is one of the key issues of solar physics, cis-lunar irradiations, astrophysics, and astroparticle physics. With the development of space astronomy, people started to realize that plasma disturbances in solar flares, Earth’s magnetosphere, and interplanetary space can also produce a large population of non-thermal particles. Cosmic ray promotion i.e. selective energization of matter in the cosmos requires, as on earth, three distinct stages: ionization, injection and acceleration to high energy. Supernova remnants and stellar winds of massive stars grouped in associations appear to be excellent celestial accelerators or re-accelerators through the shock waves they induce in their superbubbles. The injection of ions seems devoted to stars, except the smaller ones. In cosmic several mechanisms lead charged particle acceleration. Electrons are accelerated in direction of Earth’s poles by long train of electric double layers of small amplitudes. Charged particles are accelerated by the pondermotive force of electromagnetic radiation. Also, in a nonequilibrium current plasma or a plasma with particle flows, a strong electric double layer can be formed, which accelerates charged particles to high energies. The reconnection of
the magnetic field lines also leads to the acceleration of charged particles.
