Published: August 2022

Today, a comparative rethinking of the historical-pedagogical experience of forming the values of student youth through physical culture and sports in the theory and practice of the developed countries of the world, in particular the USA, is of particular importance. The article provides a comprehensive analysis of intramural sports in the USA as an important integral component of the physical education system, which contributes to the involvement of students with different levels of motor skills and qualities in active physical activity outside of school hours within the general secondary education institution. The study of positive experience in the USA on the mentioned problem is useful, taking into account the need to improve the domestic system of physical education and sports. The purpose of our research is to find out the characteristic features of the organizational, substantive and methodical support for the functioning of the system of intramural sports in the USA based on the analysis of literary sources of scientists. During the study, the following research methods were used: methods of theoretical, retrospective analysis, generalization of data from scientific and methodical literature and official documents. In the process of the conducted research, we established the peculiarities of the organization, content and methodical support of intramural sports programs in the USA. In particular, the system-logical process is described in detail, starting with the definition of the type (character) and scope of the program, types of physical (sports) activity, planning, buildings, equipment and inventory, rules of admission, determination of the winner and awards, accounting, use of modern information technology, medical review and concluding with funding, program support and promotion, arbitration, program administration and evaluation. The participation of schoolchildren in intramural sports programs is based on voluntary principles, and its numerous types are usually recreational or competitive in nature. However, these two important functions of intramural sports can be combined.

Published: August 2022

Cold spray is adding another dimension to thermal spray coating processes with numerous applications that have yet to be realized. Current activities in the field of Cold Spray are rapidly moving from R&D to commercial applications in industry. To successfully commercialize the technology, cost effective, low maintenance, highly reliable, easy to operate equipment must be available and supported that is designed so that the spray processes can be controlled and repeated. With the growth of this technology there will be a demand for laboratory systems to perform applications research and development as well as high volume production machines for specific industrial applications. The recent focus of Cold Spray equipment development has been to perfect nozzles and gun assemblies, gas heaters, gas flow, powder feed, and process control. This paper describes the automated equipment that is available in the market today and presents advances in nozzle and gas heater performance as well as development of a laboratory powder feeder. This equipment will serve as the baseline for equipment that will soon be installed in industry for commercial production applications.

Authors: Blose R.E. , Vasquez D. , Kratochvil W.
Published: August 2022

This report presents results of a new technology that looks promising to apply high quality corrosion resistant coatings in limited special areas. This technology could minimize or eliminate maintenance activities experienced today with existing corrosion preservation management systems. Four passivation coatings (aluminum, zinc, 85Zn- 15Al, and 55Al-45Zn) were deposited and evaluated using the Cold Spray process. The composite powders were not chemically alloyed but mixed by weight percent (powder alloyed) to prepare the composite mixture. Each coating was deposited with both nitrogen and helium gas. Deposition efficiency measurements were made for each powder/gas combination. Coatings were applied to DH-36 steel specimens and analyzed for quality of the bond line between the coating and substrate, porosity, bond strength, weight percent of metal constituents resident in the composite coatings, and integrity of the coating after 1000 hours of exposure to accelerated salt spray testing. Cold sprayed results are compared with specimens sprayed with aluminum using the flame sprayed process. Cost comparisons are made for depositing the various powders using both Cold Spray and flame spray processes.
Adjusted Thermal Spraying Layers to Enhance the Electromagnetic Forming of Metal Sheets
Authors: Tillmann W. , Vogli E. , Kleiner M. , Beerwald C. , Risch D.
Published: August 2022

The electromagnetic forming (EMF) is a process for forming sheet metals or thin metal tubes with a high electrical conductivity such as Al-alloys. Extremely high forming velocities can be achieved by employing this process based on pulsed electro-magnetic fields. To exploit the advantages of this process in forming sheet materials with a limited electrical conductivity thermal spraying methods have been applied. The essential requirement is based on the design and development of an electrically conductive layer system, which can act as a “driver“ for materials to be formed. Therefore, the layer has to fulfil high demands on its density as well as on the adhesion to the substrate. In this contribution a new coating concept for thin sheets to be electromagnetically formed is presented. The influences of pre-cleaning processes, coating parameters, layer properties and sheet thickness on the deformation are scrutinized. Accompanying metallographic, mechanical and microscopic investigations of the coated layers help to understand the mechanisms of materials behaviour during EMF processes.

Published: August 2022

The suspension plasma spraying (SPS) technique implemented on DC plasma spray guns is a complex thermal spraying process. In order to gain a better understanding of this deposition technique a systematic “splat” study using a shutter mechanism and the line-scan test was conducted varying liquid feedstock properties (viscosity and surface tension) and injection parameters (stream velocity and mass-loading). Splat morphology revealed the degree of particle agglomeration within the droplet formed from the liquid/plasma interaction, as well as their impacting velocity and heating history. The droplet formation was correlated to the liquid feedstock injection velocity and its viscosity. A simple model was developed to explain the experimental results correlating suspension properties to suspension droplet fragmentation mechanism.

Authors: Lugscheider E. , Zwick J. , Hertter M. , Sporer D.
Published: August 2022

The efficiency of gas turbines is highly dependent upon the clearance between compressor housing and rotating blades. Abradable seal coatings are employed to minimize the clearance and control the over-tip leakage by allowing the blade tips to cut into the coating and herewith implementing a method of self-adjustment. These coatings consist of a thermally sprayed multiphase material, comprising a metal matrix, a dislocator and a defined level of porosity. Thermally sprayed abradable linings aim at a well balanced profile of properties relevant for the application as abradable seals. Amongst others these include: abradability, ageing resistance, corrosion and oxidation resistance as well as surface finish and bond strength to substrate materials. Due to the high demands in aircraft industry, the coating properties also have to match strict requirements with regards to quality control. Hence the spraying process has to be stable and well controlled. In this work, an APS sprayed abradable coating was sprayed with different sets of parameters and analysed by an on-line diagnostic system. The coating microstructure and properties were evaluated and related to the diagnostic results.

Authors: Barbezat G.
Published: August 2022

A reduction of the size and weight of connecting rods can be obtained using the deposition of bearing materials by thermal spraying directly on the substrate. For this application several thermal spray processes are coming in competition. However the aspect of the metallurgical reactions during the coating deposition should be taken in count. The alternative of different technologies is presented with respect on the coating characteristics, the potential of industrialization and of the costs. The characteristics of the coatings are also strongly depending of the part geometry.
Fast Determination of Particle Critical Velocity in Cold Spraying
Authors: Raletz F. , Vardelle M. , Ezo’o G.
Published: August 2022

Cold spray process is a low temperature spraying method (<600°C) based on particle high kinetic energy at impact (velocity in the range 300-1200 m/s). Powder is injected in a specific designed nozzle and, there, reaches high velocity. Even if bounding mechanisms are not perfectly known, it is established that adhesion can’t exist below a definite particle velocity called critical velocity. This specific velocity depends on both powder and substrate characteristics (chemical composition, mechanical properties…). The large number of parameters makes the determination of critical velocity very complex. But it is a fundamental value to determine the correct operating conditions. This work presents an imaging technique that allows a fast measurement of critical velocity. In this paper, the measuring method is first validated by comparing the critical velocity of copper (sprayed on copper substrate) found in the literature, with the measured one. Its accuracy is then tested with other materials and, finally, some improvements of the method are proposed.

HVOF sprayed WC/Co(Cr) and Cr3C2/Ni20Cr composite coatings have gained high acceptance in many industrial applications for protection of components against wear. The achieved coatings have quite good corrosion resistance for use of chromium containing matrices. Present research in the field of PTA-Surfacing resulted in the development of high chromium and high vanadium containing iron based hard alloys with simultaneous improvement of abrasive wear and corrosion resistance. These properties of the PTA-Surfaced coatings were studied and it was found that the newly developed alloys have nearly same wear resistance and improved corrosion resistance compared to Co-based alloys reinforced with Fused Tungsten Carbides (FTC). One major advantage of high chromium and high vanadium containing iron based coatings is machinability by turning and milling processes. These features make it attractive to be used in thermal spraying. The absence of substrate melting in HVOF-spraying is advantageous, as the coatings preserve the properties of the alloy due to prevention of dilution with substrate material in contrast to PTA-Surfacing. High chromium and high vanadium containing iron based atomized powder was used for HVOF spraying and deposition efficiency was measured. The sprayed coatings were studied metallographically by optical microscopy, SEM, XRD and micro-hardness measurements. Later, abrasive wear and corrosion properties of the coatings are investigated.
Supersonic Nozzles for the Wire Arc Spraying
Authors: Wilden J. , Schwenk A. , Bergmann J.P. , Zimmermann S. , Landes K.
Published: August 2022

One of the most effecting parameters for the wire arc spraying with the regard to the properties of the sprayed coatings is the flow characteristic of the atomizing gas. Depending on the nozzle inner contour at the entrance of the torch, the atomizing gas is emanating the nozzle as a non-adjusted supersonic gas jet, either under- or over expanded. Thus, a convergent-divergent nozzle with a bell-shaped divergent exit is designed in order to generate a completely expanded atomizing gas flow inside the nozzle without any shock nodes in the emanating gas jet. The influence of the flow characteristic of the atomizing gas (air) on the droplet velocity is investigated by Laser- Doppler-Anemometry measurements. The coating quality is characterised with regard to the surface roughness and porosity.
In-Flight Behavior of Ni-Al Powder During Its Plasma Spraying
Authors: Voleník K. , Kolman B. , Dubský J. , Chráska P.
Published: August 2022

A Ni-Al pseudo-alloy powder was studied from the point of view of spheroidization during spraying by a water-stabilized plasma gun. The powder particles of irregular shape were conglomerates of elemental Ni and Al, the average Al content being 9.7 %. To conserve the shape and composition of particles flying in the plasma stream, these were trapped in liquid nitrogen. Scanning electron microscopy and X-ray microanalysis were used to obtain information about particle shape and element distribution. Most plasma sprayed particles trapped in liquid nitrogen were composed of a Ni-Al alloy, where the Al content varied in a wide range. Spherical "caps" composed of Al-oxide covered partially their surfaces. It follows that on the interface between molten Ni and Al, the interaction of both components gave rise to a Ni-Al alloy. On the contrary, if Al was exposed to air, it oxidized rapidly during the flight of the particles. The X-ray diffraction lines of the metallic phase in the particles trapped in liquid nitrogen were shifted from the positions corresponding to pure Ni as observed in the feedstock powder. This, together with the line asymmetry, showed the presence of Ni-Al alloy containing varying amounts of Al. The X-ray diffraction did not find any elemental Al in the liquid nitrogen trapped powder, i.e. neither in the metallic phase nor in the "caps". This means that all Al accessible to the ambient oxygen was converted into oxide. The "caps" contained metastable γ- and δ- Al2O3. The mechanism of the "cap" formation appears to be based on the fact that after an acceleration and melting period, significant slowing down of a molten particle occurs. Due to the drag forces, the lighter Al2O3 melt concentrates on the rear part of the droplet surface. The main condition, under which this mechanism holds, is the presence of two immiscible melts in the droplets and the significantly differing densities of both melts.

Published: August 2022

The Sulzer Metco Triplex II gun marks a new generation of three cathode plasma guns. In opposition to conventional single cathode guns, it features a stationary plasma jet. Liquid precursors, wire- and powder shaped spray materials were processed with a modified Triplex II gun under controlled atmosphere and characteristics of the obtained coatings were investigated. A new shroud system was developed to handle susceptible to oxidation and reactive materials such as Ti and B4C. A conception of a wire conveyance system enables the handling of three wires of titanium simultaneously. Furthermore a liquid spray material feed system, for the generation of Al2O3-coating with low porosity based on nanoparticle suspensions, was developed and built. All coatings, which were manufactured by the different procedures, are characterized comprehensively by means of optical microscopy (OM) including interactive image analysis, scanning electron microscopy (SEM) with attached electron dispersive X-ray analysis (EDX) system, X-ray diffraction (XRD) and microhardness.
Some Key Advices for the Modeling of Plasma Jets using FLUENT
Authors: Bolot R. , Li J. , Coddet C.
Published: August 2022

Many CFD software packages are commonly used for the modeling of thermal plasma jets. Unfortunately, according to some recent results reported in the literature, one may notice that two different software products do not always provide similar results for a similar case. For example, PHOENICS and FLUENT were recently used in a single study and some abnormal differences were observed in the numerical predictions [1]. After some intensive search, the reasons were identified and are explained in the present paper: it appears that all Fluent built-in k-å type turbulence models have to be modified especially for high temperature flows. Since Fluent is now extensively used for the modeling of plasma jets, it was considered useful to report the required correction to the scientific thermal spray community and this is the purpose of the present paper.

Authors: Gao Y. , An L. , Kang Y.
Published: August 2022

Compound coatings of MCrAlY and alumina shows a sandwich structure with good wear-resistance and intensity at elevated temperature, the coating are usually applied to the furnace roll in modern continuously annealing line or continuously galvanizing line, to prevent the pickup forming on the roll surface. Coatings were prepared by the detonation spraying and the effect of spraying parameter of the denotation gas composition on the microstructure of coatings was investigated. The percentages of MCrAlY and alumina in the coating were determined by the composition of detonation gas mixture. Alumina content in the coating increased with the reduction of the nitrogen dilution in the gas mixture, which resulted in the hardness enhancement of the coating. The microstructure of coatings is different from that prepared by thermal plasma spraying or HVOF.

Authors: Gruner H. , Gruner Ph. , Moens J.
Published: August 2022

The reliability and reproducibility of thermal sprayed coatings depend, apart from all other coating parameters, on a regular powder flow into the energy source. During the coating development, all parameters are optimized in respect to the coating application. Unfortunately with some desired coating conditions, the powder feeding becomes a difficult process. Quality management is not just a topic for medical and aerospacial industry, it has become increasing importance to all branches. Therefore the mechanic, volumetric powder dosing, which is now state of the art for thermal spraying, will be replaced by gravimetric supported and / or digitally controlled systems which combines high precision and permanent data control and storage. In this presentation the powder feeding process is described, beginning at the powder stock and ending at the injection into the energy source. Technical difficulties are discussed and actual solutions to improve the process are presented.

Students’ Expectations of Offline Learning Road to Endemic Covid-19 Status as the Effect of Online Learning
Authors: Alriavindrafunny Rindu
Published: August 2022

Many methods and strategies of learning were being searched, made, and invented by a lecturer to provide an effective online learning process. Two years passed, and now Indonesia is on the road to endemic of covid-19 status, which soon caused the permission for offline learning. Indeed, students have their own expectations for this condition. Do they like it? Do they have difficulties so far? Do they want other methods? or other expectations of students which have not been explored yet? Therefore, this research will explore students' expectations of welcoming offline learning using a qualitative research method. The questionnaire was used as the instrument to collect the data from the students in the first year of the pandemic. The instrument mostly asked about the students' opinion of their online learning, then related to their expectations when it became offline learning soon. It was simply analyzed using excel to show the percentage of each data. The result showed that 75% did not like online learning since it impacts their score, which decreased from an average of about 70 to 50. Therefore, many students expect to understand the material with offline learning (80%) better than online. The reason for being less understandable with online learning and the decreasing score of students, becomes the evaluation of online learning found in this research. That strongly becomes the reason why the students expect to have a better understanding of offline learning in 2022

(Un)Doing the Colombian Armed Conflict
Authors: Olarte-Sierra María Fernanda
Published: August 2022

English Abstract:
In 2005, Colombia enacted the Justice and Peace Law, which was a transitional framework for addressing the legal status of demobilised members of the paramilitary group Autodefensas Unidas de Colombia [United Self-Defence of Colombia] and other armed groups. In exchange for providing intelligence on the whereabouts of the bodies of people these groups had kidnapped and killed, prison sentences could be reduced. Forensic experts from the Attorney General’s Office were in charge of exhuming and identifying the bodies, placing them centre-stage as a source of scientific evidence, testimony and authority based on their presumed objectivity and non-prejudicial approach. However, forensic knowledge, like all knowledge, is situated, partial and performative. Here, I attend to the effects of forensic knowledge on victims’ right to truth, memory practices and the administration of justice under the Justice and Peace Law. I argue that forensic knowledge co-produces conflict by producing victims and perpetrators whose identities and stories can be at odds with other accounts of the violence that occurred.

French Abstract:
En 2005, la loi sur la justice et la paix a été promulguée en Colombie. Il s’agissait d’un cadre transitoire permettant de régler le statut juridique des membres démobilisés du groupe paramilitaire Autodefensas Unidas de Colombia [Autodéfenses unies de Colombie] et d’autres groupes armés. Cette loi prévoyait la réduction des peines de prison en échange de renseignements sur l’emplacement des corps des personnes que ces groupes avaient enlevées et tuées. Des experts médico-légaux du bureau du procureur étaient chargés d’exhumer et d’identifier les corps. Cela les plaçait au centre de la scène en tant que source de preuves scientifiques, de témoignages et d’autorité, en raison de leur objectivité présumée et de leur approche non préjudiciable. Cependant, la connaissance médico-légale, comme toute connaissance, est située, partielle et performative. Je m’intéresse ici aux effets des connaissances médico-légales sur le droit des victimes à la vérité, les pratiques de mémoire et l’administration de la justice dans le cadre de la loi Justice et Paix en Colombie. Je soutiens que les connaissances médico-légales coproduisent des conflits en produisant des victimes et des auteurs dont les identités et les histoires peuvent être en contradiction avec d’autres récits de la violence qui s’est produite.
Situating the Investigation on Clandestine Graves in Mexico
Authors: Robledo Silvestre Carolina , Ramírez González Paola Alejandra
Published: August 2022

English Abstract:
Over 90,000 people have been disappeared as a result of the War on Drugs that takes place in Mexico. Most of them are young people from poverty-stricken communities, stigmatised and targeted by an ongoing military campaign for their alleged connection to ‘organised crime’. Drawing on the experience of the search for bodies in hidden mass graves initiated by a group of mothers of those who have disappeared in the state of Sinaloa (Mexico), this article aims to provide a comprehensive reflection of the emotional turn and the forensic turn, from a feminist perspective. Our ethnographic contribution focuses on how Las Buscadoras (The Searching Women) resist rational acts related to the legal and scientific treatment of dead bodies through the mobilisation of symbolic, ritualistic and political community actions that reveal novel forms of affective recognition of and care for the dead. This, we argue, has resulted in a plurality of practices and meanings around truth and justice.

French Abstract:

La plupart d’entre elles sont des jeunes issus de communautés pauvres, stigmatisés et ciblés par une campagne militaire permanente en raison de leurs liens supposés avec le « crime organisé ». S’appuyant sur l’expérience de la recherche de corps dans des fosses communes cachées initiée par un groupe de mères de disparus dans l’État de Sinaloa (Mexique), cet article vise à fournir une réflexion globale sur le tournant émotionnel et le tournant médico-légal, dans une perspective féministe. Notre contribution ethnographique se concentre sur la façon dont Las Buscadoras (les femmes qui cherchent) résistent aux actes rationnels liés au traitement légal et scientifique des cadavres par la mobilisation d’actions communautaires symboliques, rituelles et politiques qui révèlent de nouvelles formes de reconnaissance affective et de soins pour les morts. Nous soutenons que cela a donné lieu à une pluralité de pratiques et de significations autour de la vérité et de la justice.

Authors: Huang Xiao , Nie Fang , Zhu Ju , Liu Luping , Wang Nan
Published: August 2022

BACKGROUND: Conventional ultrasound (US), which include gray scale US and Doppler US, is the first-line imaging modality for the evaluation of renal allograft; however, conventional US indicators have limitations. OBJECTIVE: To explore the application value of shear-wave elastography (SWE) combined with monochrome superb microvascular imaging (mSMI) in renal allograft chronic rejection (CR). METHODS: From November 2021 to February 2022 in the Lanzhou University Second Hospital, the US features of 54 patients with renal allograft were retrospectively analyzed. Patients were categorized into two groups: stable group(n = 44) and CR group(n = 10), with clinical diagnosis as reference standard. The vascular index (VI) on mSMI and parenchymal stiffness were measured in the middle cortex of all renal allografts and receiver operating characteristic (ROC) curves were drawn to evaluate the feasibility of differentiation. Statistically significant US features and biochemical indicators such as creatinine were scored, and the results of the scores were analyzed by ROC curve. RESULTS: The VI on mSMI of the stable group (49.5±2.0) was significantly greater than that of the CR group (33.8±5.9) (P = 0.028). There was a statistically significant difference in parenchymal stiffness between stable group (16.2kPa±1.2) and CR group (33.9kPa±6.6) (P = 0.027). The sensitivity was 90% and specificity was 81.8% of the scores in the differentiation of stable group from CR group (cut-off value, 2; P = 0.000). CONCLUSION: SWE combined with mSMI may help differentiate stable renal allograft from renal allograft CR and have the potential application value in the diagnosis of renal allograft CR.

We study the sequence ta,b(n) = T(Kn; a, b) where a, b are integers, and show that for every μ ∈ ℕ the sequence ta,b(n) is ultimately periodic modulo μ provided a ≠ 1 mod μ and b ≠ 1 mod μ. This result is related to a conjecture by A. Mani and R. Stones from 2016. The theorem is a consequence of a more general theorem which holds for a wide class of graph polynomials definable in Monadic Second Order Logic. This gives also similar results for the various substitution instances of the bivariate matching polynomial and the trivariate edge elimination polynomial ξ(G; X, Y, Z) introduced by I. Averbouch, B. Godlin and the second author in 2008. All our results depend on the Specker-Blatter Theorem from 1981, which studies modular recurrence relations of combinatorial sequences which count the number of labeled graphs.

Background: We previously reported the effects of a probiotic strain, Bifidobacterium breve MCC1274, in improving cognitive function in preclinical and clinical studies. Recently, we demonstrated that supplementation of this strain led to decreased amyloid-β production, attenuated microglial activation, and suppressed inflammation reaction in the brain of APP knock-in (AppNL - G - F) mice. Objective: In this study, we investigated the plasma metabolites to reveal the mechanism of action of this probiotic strain in this Alzheimer’s disease (AD)-like model. Methods: Three-month-old mice were orally supplemented with B. breve MCC1274 or saline for four months and their plasma metabolites were comprehensively analyzed using CE-FTMS and LC-TOFMS. Results: Principal component analysis showed a significant difference in the plasma metabolites between the probiotic and control groups (PERMANOVA, p = 0.03). The levels of soy isoflavones (e.g., genistein) and indole derivatives of tryptophan (e.g., 5-methoxyindoleacetic acid), metabolites with potent anti-oxidative activities were significantly increased in the probiotic group. Moreover, there were increased levels of glutathione-related metabolites (e.g., glutathione (GSSG)_divalent, ophthalmic acid) and TCA cycle-related metabolites (e.g., 2-Oxoglutaric acid, succinic acid levels) in the probiotic group. Similar alternations were observed in the wild-type mice by the probiotic supplementation. Conclusion: These results suggest that the supplementation of B. breve MCC1274 enhanced the bioavailability of potential anti-oxidative metabolites from the gut and addressed critical gaps in our understanding of the gut-brain axis underlying the mechanisms of the probiotic action of this strain in the improvement of cognitive function.

BACKGROUND:

Scaling and root planing [SRP] being the mainstay of treatment of periodontitis encompasses unambiguous impediments. antiseptics represent an aid to nonsurgical periodontal therapy.

OBJECTIVE:

This randomized controlled, split mouth study design with an observation period of three months aims to clinically evaluate the efficacy of ozonised oil and chlorhexidine as an adjunct to SRP.

METHODS:

Twenty-five patients of both sexes with an age range of 30–65 years diagnosed with chronic periodontitis and having a periodontal probe depth (PD)≥5 mm and CAL≥3 mm on at least 1 site in each quadrant were included in this randomised split mouth design study. Patients were allocated in 2 experimental treatment groups as SRP + chlorhexidine gel (control sites) and with SRP + ozone oil (test sites). The plaque index (PI), gingival index (GI), and periodontal pocket depth (PPD), clinical attachment level (CAL) were recorded at baseline data and after 30 days post-baseline.

RESULTS:

The present study showed significant results in both the groups with regards to the improvement in the clinical parameters. When comparison was made between the two groups, it has been assessed that the use of the ozonized oil in addition to SRP did not show significant differences when compared to conventional SRP + chlorhexidine.

CONCLUSION:

For bye to SRP, ozonized oil can be considered as a viable alternative to chlorhexidine in the treatment of periodontitis, especially considering its low toxicity compared to chlorhexidine.

In order to ensure the safe transmission of the information of the secondary distribution system across the regional network, this paper studies a security monitoring method of the secondary distribution system across the regional network based on the Internet of things technology and the improved fuzzy clustering algorithm. The Internet of things technology is used to collect the information transmission in cross region network of the secondary power distribution system and store it in the database; Combined with the shadow set to improve the basic fuzzy C-means clustering algorithm, the improved fuzzy C-means clustering algorithm is obtained. The cross region information transmission in the clustering database is divided into two categories: security and risk, and the risk information obtained by clustering is divided into four risk types, so as to realize the security monitoring of information transmission in cross region network of secondary power distribution system. The results show that the average monitoring rate of this method can reach 93.93%, the information collection is efficient and accurate, the number of packet losses is low, and the clustering results are stable and reliable, which can ensure the safe information transmission of cross region network of the secondary power distribution system.

Published: August 2022

Multiple system atrophy (MSA) is a sporadic and progressive neurodegenerative disorder with a complex differential diagnosis. A range of disorders— also of nondegenerative etiology— can mimic MSA, expanding its differential diagnosis. Both misdiagnosis and diagnostic delays are relatively common in clinical practice. A correct diagnosis is vital for daily clinical practice, in order to facilitate proper counselling and to timely install therapies in treatable disorders that mimic MSA. A correct diagnosis is also essential for including properly classified individuals into research studies that aim to better understand the pathophysiology of MSA, to develop specific biomarkers or to evaluate novel symptomatic or disease-modifying therapies. Here, we offer some practical guidance to support the diagnostic process, by highlighting conditions that may be considered as MSA lookalikes, by emphasizing some key clinical aspects of these mimics, and by discussing several useful ancillary diagnostic tests.
GBA1 and The Immune System: A Potential Role in Parkinson’s Disease?
Authors: Al-Azzawi Zaid A.M. , Arfaie Saman , Gan-Or Ziv
Published: August 2022

It is clear that the immune system and inflammation have a role in Parkinson’s disease (PD), including sporadic PD and some genetic forms such as LRRK2-associated PD. One of the most important genes associated with PD is GBA1, as variants in this gene are found in 5–20% of PD patients in different populations worldwide. Biallelic variants in GBA1 may cause Gaucher disease, a lysosomal storage disorder with involvement of the immune system, and other lines of evidence link GBA1 to the immune system and inflammation. In this review, we discuss these different pieces of evidence and whether the interplay between GBA1 and the immune system may have a role in PD.

PURPOSE: This pooled analysis of data from three Phase 3 studies investigated the effects of incobotulinumtoxinA on spasticity-related pain (SRP) in children/adolescents with uni-/bilateral cerebral palsy (CP). METHODS: Children/adolescents (ambulant and non-ambulant) were evaluated for SRP on increasingly difficult activities/tasks 4 weeks after each of four incobotulinumtoxinA injection cycles (ICs) using the Questionnaire on Pain caused by Spasticity (QPS; six modules specific to lower limb [LL] or upper limb [UL] spasticity and respondent type [child/adolescent, interviewer, or parent/caregiver]). IncobotulinumtoxinA doses were personalized, with all doses pooled for analysis. RESULTS: QPS key item responses were available from 331 and 155 children/adolescents with LL- and UL-spasticity, respectively, and 841/444 (LL/UL) of their parents/caregivers. IncobotulinumtoxinA efficacy was evident with the first IC. Efficacy was sustained and became more robust with further subsequent ICs. By Week 4 of the last (i.e. fourth) IC, 33.8–53.3% of children/adolescents reported complete SRP relief from their baseline pain for respective QPS items. Children/adolescents reported reductions in mean LL SRP intensity at levels that surpassed clinically meaningful thresholds. Similarly, parents/caregivers observed complete SRP relief and less frequent SRP with incobotulinumtoxinA. Similar results were found for UL SRP. CONCLUSION: These findings indicate that incobotulinumtoxinA could bring considerable benefit to children/adolescents with spasticity by reducing SRP, even during strenuous activities.
