Smart gloves have been under development during the last 40 years to support human-computer interaction based on hand and finger movement. Despite the many devoted efforts and the multiple advances in related areas, these devices have not become mainstream yet. Nevertheless, during recent years, new devices with improved features have appeared, being used for research purposes too. This paper provides a review of current commercial smart gloves focusing on three main capabilities: (i) hand and finger pose estimation and motion tracking, (ii) kinesthetic feedback, and (iii) tactile feedback. For the first capability, a detailed reference model of the hand and finger basic movements (known as degrees of freedom) is proposed. Based on the PRISMA guidelines for systematic reviews for the period 2015–2021, 24 commercial smart gloves have been identified, while many others have been discarded because they did not meet the inclusion criteria: currently active commercial and fully portable smart gloves providing some of the three main capabilities for the whole hand. The paper reviews the technologies involved, main applications and it discusses about the current state of development. Reference models to support end users and researchers comparing and selecting the most appropriate devices are identified as a key need.

Cryopreservation Method

 Commercial artificial insemination with boar semen still prefers the usage of refrigerated semen up to 5 days over frozen-thawed, to date. This is because of the uneconomical properties of frozen-thawed boar semen, such as low motility, viability, fertility rates and the need for higher semen doses, because of the decreased quality after cryopreservation. Since boar semen is highly susceptive to cold shock damage, the invention of a successful cryopreservation method would be greatly beneficial for the swine industry. This review briefly focuses on the many factors that influence the quality of frozen-thawed boar semen, including the different compositions of extenders, comparison of commercial extenders, freezing and thawing methods (temperature and duration). It could be concluded from the present review that optimum freezing/thawing protocol for swine is not standardized, so far being the current status still considered poor-to-fair.

Abstract Introduction Management of concomitant use of ART and TB drugs is difficult because of the many drug–drug interactions (DDIs) between the medications. This systematic review provides an overview of the current state of knowledge about the pharmacokinetics (PK) of ART and TB treatment in children with HIV/TB co-infection, and identifies knowledge gaps. Methods We searched Embase and PubMed, and systematically searched abstract books of relevant conferences, following PRISMA guidelines. Studies not reporting PK parameters, investigating medicines that are not available any longer or not including children with HIV/TB co-infection were excluded. All studies were assessed for quality. Results In total, 47 studies met the inclusion criteria. No dose adjustments are necessary for efavirenz during concomitant first-line TB treatment use, but intersubject PK variability was high, especially in children <3 years of age. Super-boosted lopinavir/ritonavir (ratio 1:1) resulted in adequate lopinavir trough concentrations during rifampicin co-administration. Double-dosed raltegravir can be given with rifampicin in children >4 weeks old as well as twice-daily dolutegravir (instead of once daily) in children older than 6 years. Exposure to some TB drugs (ethambutol and rifampicin) was reduced in the setting of HIV infection, regardless of ART use. Only limited PK data of second-line TB drugs with ART in children who are HIV infected have been published. Conclusions Whereas integrase inhibitors seem favourable in older children, there are limited options for ART in young children (<3 years) receiving rifampicin-based TB therapy. The PK of TB drugs in HIV-infected children warrants further research.

Objective . Robotic surgery has gained ground in recent years in benign and malignant gynecological interventions. The purpose of this article is to present the main indications of robotic surgery, to identify the advantages and disad­van­tages of this surgical technique and to present our ex­pe­rience in this field. Materials and method. An analysis of ar­ti­cles published in literature to observe the in­di­ca­tions of robotic surgery in gynecology, both for be­nign and ma­lig­nant interventions. Comparison of li­te­rature data with the main surgical indications found in the pa­tient group selected by us who received robotic sur­ge­ry. Results . The integration of robotic technology is a significant advance in the minimal invasive treatment techniques of the gynecological pathology used to treat both benign and malignant conditions. The advantages of robotic surgery are: 3D view of the operator field, superior dexterity, seven degrees of freedom for the movement of the brushes, superior capability of stitches and knots, superior ergonomics, elimination of the effect of the rebound, movement of the movements and reduction of tremor. The disadvantages of surgery are: the high cost of surgery, the lack of tactile feedback and the increased size of the device. Conclusions . Robotic surgery is an effective, safe and feasible method for the treatment of benign and malignant gynecological disorders. The optimal knowledge of trocars (adapted to the body mass index of each patient) is important in order to benefit from all the advantages of robotic surgery. Regarding the robotic surgical treatment group in which the feasibility of this procedure was observed, there are: oncological interventions, endometriosis, in reproductive medicine and in obese patients.

Abstract Comprehensive accounts of resource-rational attempts to maximise utility shouldn't ignore the demands of constructing utility representations. This can be onerous when, as in humans, there are many rewarding modalities. Another thing best not ignored is the processing demands of making functional activity out of the many degrees of freedom of a body. The target article is almost silent on both.

The International conference “Flora and conservation in the Caucasus: history and current state of knowledge” dedicated to the 130-year anniversary of the Perkalsky Arboretum took place at 22–25 of May 2019 in Pyatigorsk (Stavropol Territory) on the base of the Pyatigorsk Museum of local lore and natural history. The participants were from 11 cities of Russia and 7 Republics of the Caucasus and represented 14 institutions. Proceedings of the conference were published by the beginning of the meeting the book of abstracts includes 49 papers on the study of vascular plants, bryophytes, lichens and fungi, plant communities, as well as the protection of rare and endangered species, unique plant communities, and ecological problems in the Caucasus. The following geobotanical topics were highlighted in 13 papers: forest communities (3 reports), meadow and steppe vegetation (2), xeric open forests (2), communities of ecotone areas (1), structure of populations of rare plant species (3), as well as the history and current status of nature protected areas (2). The great emphasis has been focused on the study of floristic composition and plant populations. Thus, the conference showed that very few studies от vegetation are currently carried out in the Caucasus, and a lot of districts are not affected by the research. The greatest attention is paid to forest vegetation while meadow, steppe, alpine heath and xerophytic communities are studied rather poorly. Besides, there are “white spots” — mire, floodplain and aquatic vegetation. In nowadays, when the anthropogenic impact on the plant cover of the Caucasus is intensively increasing, it is especially important to study natural undisturbed communities preserved in protected natural areas. Another important issue is the conservation of the unique vegetation cover of the whole Caucasus. Thus, the study of vegetation of this region opens a wide field for researchers using various methods of modern plant science.

The Impact

Abstract Racial and ethnic disparities are endemic to the United States and are only beginning to attract the attention of researchers. With an increasingly diverse population, focused and tailored medicine to provide more equitable care is needed. For surgical trauma populations, this topic is a small but expanding field and still rarely mentioned in burn medicine. Disparities in prevention, treatment, and recovery outcomes between different racial and ethnic minorities who are burned are rarely discussed. The purpose of this study is to determine the current status of identified disparities of care in the burn population literature and areas of future research. A systematic review was conducted of literature utilizing PubMed for articles published between 2000-2020. Searches were used to identify articles that crossed the burn term (burn patient OR burn recovery OR burn survivor OR burn care) and a race/ethnicity and insurance status-related term (race/ethnicity OR African-American OR Black OR Asian OR Hispanic OR Latino OR Native American OR Indigenous OR Mixed race OR 2 or more races OR socioeconomic status OR insurance status). Inclusion criteria were English studies in the US that discussed disparities in burn injury outcomes or risk factors associated with race/ethnicity. 1,169 papers were populated, 55 were reviewed, and 36 articles met inclusion criteria. Most studies showed minorities had poorer inpatient and outpatient outcomes. While this is a concerning trend, there is a paucity of literature in this field and more research is needed to create culturally-tailored medical care and address the needs of disadvantaged burn survivors.

ABSTRACT This study aims at presenting the process of machine design and agricultural implements by means of a reference model, formulated with the purpose of explaining the development activities of new products, serving as a guideline to coach human resources and to assist in formalizing the process in small and medium-sized businesses (SMB), i.e. up to 500 employees. The methodology used included the process modeling, carried out from case studies in the SMB, and the study of reference models in literature. The modeling formalism used was based on the IDEF0 standard, which identifies the dimensions required for the model detailing: input information; activities; tasks; knowledge domains; mechanisms; controls and information produced. These dimensions were organized in spreadsheets and graphs. As a result, a reference model with 27 activities and 71 tasks was obtained, distributed over four phases of the design process. The evaluation of the model was carried out by the companies participating in the case studies and by experts, who concluded that the model explains the actions needed to develop new products in SMB.

We address the problem of computing the hydrodynamic forces and torques among $N$ solid spherical particles moving with given rotational and translational velocities in Stokes flow. We consider the original fluid–particle model without introducing new hypotheses or models. Our method includes the singular lubrication interactions which may occur when some particles come close to one another. The main new feature is that short-range interactions are propagated to the whole flow, including accurately the many-body lubrication interactions. The method builds on a pre-existing fluid solver and is flexible with respect to the choice of this solver. The error is the error generated by the fluid solver when computing non-singular flows (i.e. with negligible short-range interactions). Therefore, only a small number of degrees of freedom are required and we obtain very accurate simulations within a reasonable computational cost. Our method is closely related to a method proposed by Sangani & Mo (Phys. Fluids, vol. 6, 1994, pp. 1653–1662) but, in contrast with the latter, it does not require parameter tuning. We compare our method with the Stokesian dynamics of Durlofsky et al. (J. Fluid Mech., vol. 180, 1987, pp. 21–49) and show the higher accuracy of the former (both by analysis and by numerical experiments).

the article analyzes the influence of cultural, social, religious, scientific and technical factors on the histori-cal development, current status and future directions of development of the architecture of medical institu-tions in Yemen. The research attempted to study the features of the work of medical institutions in Yemen. The study begins with a description of the literature on a general overview of the location, geographic sec-tions, climate and economy of the port city of Yemen. The study describes the problems and factors that influence the design of medical institutions in Yemen. The current situation demonstrates a tendency to-wards centralization of attention on the patient himself and the doctor-patient system. The hospital should create the most comfortable conditions for the patient, and the medical staff acts as consultants. That is, pa-tients should receive maximum attention, sympathy and psychological assistance. Based on this position, architectural decisions should take into account the relationship between the doctor and the patient. The ar-chitectural design of medical facilities in hot climates should be carried out taking into account the regional characteristics of the environment. The choice of a construction site for the architectural and planning organ-ization of a network of medical institutions for children and adults must be made based on the general con-ditions for the development of the city and its suburban area. The theoretical and methodological basis of the study are the provisions and conclusions of the works of domestic and foreign scientists in the field of development of the architecture of medical institutions. The research used materials from scientific seminars and conferences. In the process of research, a systematic approach and logical analysis methods were used. The scientific literature notes that the modern concept of the formation of the architectural and spatial environment of urban hospitals is associated with modern medical technologies, as well as with the increasing role of medical institutions at the present stage.
