Authors: Mikulak Hillary , Gordon-Evans Wanda J. 
Published: December 2021

PICO question
In dogs with gastrointestinal foreign-body obstruction undergoing surgical correction, is the mortality rate in the perioperative period for those receiving resection and anastomosis higher, lower, or equivalent to those receiving an enterotomy?

Clinical bottom line
Category of research question
Outcome
The number and type of study designs reviewed
Four retrospective studies were reviewed
Strength of evidence
Weak
Outcomes reported
It would appear that the mortality rate for resection and anastomosis for the purpose of foreign-body removal is higher than that of enterotomies performed for the same reason
Conclusion
There is insufficient evidence directly comparing enterotomies with resection and anastomoses in foreign-body obstructions to definitively state that the mortality rate is higher among resection and anastomosis procedures

How to apply this evidence in practice
The application of evidence into practice should take into account multiple factors, not limited to: individual clinical expertise, patient’s circumstances and owners’ values, country, location or clinic where you work, the individual case in front of you, the availability of therapies and resources.

Zbrodnicze umysły i muzyczne harmonie. „Tajemnica Edwina Drooda” Charlesa Dickensa jako utwór protodetektywistyczny
Authors: Kokot Joanna 
Published: December 2021

The paper analyses the role of music in Dickens’ last, unfinished novel and its relation to the criminal puzzle which — for obvious reason — was left unsolved. Contrary to the traditional cultural associations (harmony, beauty, order), music in The Mystery of Edwin Drood is related to darkness, which shrouds the places where it is performed (the cathedral, Jasper’s room); it also functions as the background of various disharmonies (physical indisposition, quarrel, signs of hatred, fear). The theme of the only two religious songs that are referred to is sin and wickedness. On the one hand, considering the fact that music is John Jasper’s domain, the discordance not only functions as an “ethical metaphor” and externalization of the man’s character, but also points to him as the murderer of his nephew. On the other hand, the aforementioned songs foreground the motif of repentance or turning away from sin, which undermines the ostensibly obvious conclusions concerning Jasper’s guilt.
Similarly to the detective novel of the (much later) Golden Age period, the hints prompting the puzzle’s solution are provided here, though they are not univocal, leaving a shadow of doubt as to the guilt of the most obvious suspect. Yet, contrary to the genre conventions, the clues appear mainly on the implied level of communication, available to the implied reader deciphering textual patterns and not merely “observing” the presented reality.

For industrial complexes artificial microclimate (ICAM) proposed a methodology to develop a comprehensive mathematical model of industrial air conditioning in the space of a condition that involves the analysis of the structure of an automatic control system (ACS) and the development of appropriate control algorithms. On the basis of the developed methodology received a comprehensive model for technological schemes of industrial air conditioners as a single multidimensional control object. For the proposed methods use dynamic models of climatic equipment in the space of States . For the General model ICAM presents matrices that define a comprehensive model of industrial air conditioner with a steam humidifier. The algorithm of synthesis of multidimensional linear-quadratic digital controller (LQDC) for ICAM developed. The problem of synthesis of optimal LQDC considered and synthesized matrix feedback LQDC, which the state parameters of the control object determines the trajectory of the vector of optimal exposure that minimizes the quadratic criterion. From the classical procedure of synthesis LQDC the proposed algorithm is characterized by the presence of the logical selection of accessories for optimal control. This approach allows us to rethink the synthesis of ACS, as air conditioning is based on the separation of the mutual impact of the regulatory options. This allows you to transfer the control system is conditioned to a qualitatively new level and ensures the efficient use of energy for artificial microclimate systems. The obtained formulas are recommended experts on design automation of control systems and optimization of existing ones.
Method of parametric studies of computational models first approximation of the aircraft with aerostatic SUPPORT
Authors: Олег Львович Лемко  , І. В. Король  
Published: December 2021

In recent years, scientists of the leading countries of the World, designers, specialists of different industries are paying close attention to aircrafts lighter than air. These aircraft use much less fuel than similar planes and helicopters with load capacity, capable to transport heavy loads on thousands of miles away, with the possibility of landing on unprepared sites or hang in the air for a long time with a cargo during the construction works. In addition, they provide a significant increase in safety of the flight in their exploitation.One of the most promising types of airships are aircraft with aerostatic support (hybrid airships) using two principles generate lift: aerodynamic and aerostatic. They can incorporate the best qualities of the airplane (speed), the airship (large capacity and range), and helicopter (the possibility of implementing a short or vertical takeoff and landing).For the formation of aerodynamic lift of the aircraft needs a wing only. All other units of aircraft not involved in the creation of lift is desirable to place inside the wing. Therefore, for the further research we chose an aerodynamic scheme called "flying wing". This scheme is the most rational for using the force of the aerostatic lifting gas, which is located inside the wing.To solve the problem in the research we used the method of calculation of the aerodynamic characteristics of aircraft in the parameters of similarity, which allows estimating the aerodynamic behavior of the wing-form in design with linear edges. It is necessary to determine the optimal layout of the wing and its aerodynamic performance in conditions of using more force of aerostatic lifting gas, concluded in the interior of the wing.With an increase of the relative profile thickness from 8% to 30% the maximal aerodynamic efficiency will be reduced from 14 to 11 units. However, the loss of quality can be compensated to fill the inner cavity of the wing lifting gas. This makes an additional component of the aerostatic force. For example the model with the relative thickness profile of 30%, and aerostatic lift 171 kg is considering.Thus we had made the analysis of changes in aerodynamic and aerostatic characteristics of the computational model of the first approximation of the aircraft with aerostatic support of the relative thickness profile. The expediency of using thick sections D-2 of the Central Aero-Hydrodynamic Institute for the aircraft scheme "flying wing" with aerostatic support was shown.As the analysis of dependencies КΣ = f (α) and the relative thickness of the wing profile = 30%, the maximum aerodynamic efficiency КΣ мах corresponds to 12 units. The same value of Кмах wing without aerostatic support in the relative thickness of the wing profile amounts 20% (= 20%).
Reducing the Specular Properties of Metalized Teflon Coverings on Canadian Mobile Servicing Station on the International Space Station
Authors: Kleiman Jacob 
Published: December 2021

A surface modification process was developed for the metalized Teflon coverings used for thermal protection of electronic equipment on the International Space Station [1]. The developed modification process of Teflon surfaces reduced substantially the specularity of Ag-Inconel coated Teflon thermal control films by changing the morphological appearance of their surfaces by ion-beam texturing in a controlled manner from a metallic-like and shiny to complete milky, white appearance without significantly affecting the thermal optical properties.
A number of space hardware units covered with the textured Silver-Teflon were exposed to the open space environment between June 2002 and June 2006 and delivered back to Earth at the end of 2006. Remarkable performance was demonstrated by the treated Ag/Teflon, with the solar absorptance and total emittance values and the α/ε ratio remaining very close to the original values as measured before the flights [2].
In an attempt to protect further the textured surfaces of Teflon from possible erosion by atomic oxygen and VUV in LEO environment, an additional novel surface modification process was developed that created an SixOyCzFn type of structure on the treated surface. The textured Teflon samples before and after surface treatments were tested in a space simulator facility under a combined atomic oxygen/vacuum ultraviolet exposure. A number of advanced characterization techniques were used to evaluate the properties of the modified films [3].
NITRO CELLULOSE POWDER CHARGES OF LONG SERVICE LIFE: PROBLEMS AND THEIR POSSIBLE SOLUTIONS
Authors: Baulin D. 
Published: December 2021

One of the components of the problem of Ukraine's national security is the loading of warehouses with a variety of ammunition with an expired guaranteed storage period.
The experience of storing ammunition shows that during long-term storage, propylene powder used in ammunition is capable of spontaneously undergoing various physical and chemical transformations, which negatively affects the ballistic characteristics of ammunition. The lack of ammunition production in Ukraine has led to the fact that ammunition is currently in operation, the storage time of which reaches 25-30 years or more.
This article analyzes publications devoted to scientific research related to the problems of ballistic stability of propellants.
A number of factors are presented that affect the physicochemical stability of powder charges during their long-term operation.
The generalizing data on changes in the main ballistic characteristics of ammunition at different periods of their storage are presented.
It is assumed that one of the ways to improve the ballistic and energy characteristics of ammunition with long service lives can be the regeneration of nitrocellulose powder charges. It is shown that at present there are no methods for the regeneration of propellant charges of long service life. However, there are encouraging data on the treatment of propellants with hydrogen peroxide, on the basis of which a technology can be developed for the complete or partial restoration of the ballistic and energy characteristics of the propellant charge.
It is presented that the predictive assessment of changes in the characteristics of ammunition with long service lives does not correspond to their real indicators.
It has been determined that the problem of nitrocellulose propellants of long service life is complex and, on the basis of its solution, theoretical and methodological foundations of the regeneration of nitrocellulose propellant charges can be developed to homologate the ballistic and energy characteristics of ammunition.

To study the effect of shock wave load on the body elements of vehicles, a setting has been developed that takes into account the mobile nature of this load. A specialized parametric finite-element model of the body layout has been created armored-carrier, taking into account the peculiarities of the studied process. The problem of determining the stress-strain state armored-hulls solved in static and dynamic formulation. The space-time distributions of components and characteristics of the stress-strain state of the investigated model armored-carrier of armored hulls are given. The results of research in the used formulations indicate the need to solve the problem in a complete dynamic formulation with account for plastic deformations. This establishes a new methodology for the rational choice of engineering solutions.

Published: December 2021

The article is devoted to the actual problem of increasing the performance indicators of machine gear drives. To solve this problem, in the article proposed to use a conchoidal engagement made with a shifting of the reference profile and special contact conditions. A feature of the proposed engagement is that it is less sensitive to manufacturing and assembly errors compared to conventional conchoidal engagement. As a result of theoretical studies, the performance indicators of such an engagement were determined. This made it possible to determine the level of load during further experimental tests of new gears. Contact strength and meshing losses were selected as performance indicators subject to further experimental verification. The ratios of these indicators, calculated for conchoidal spur gears with convex-convex contact, made with a shifting of the reference profile, with similar involute ones, are theoretically determined. Comparative analysis of performance indicators was carried out for gears of involute and conchoidal engagement with the same parameters and shifting of the reference profile. It was found that for experimental conchoidal drives with shifting, the maximum load is 1.2 times higher than that of a similar involute drive with shifting, and the loss in engagement is 21% less. A rational area of application of the new gearing is machine drives for high power transmissions.

Published: December 2021

Abstract
BackgroundDiabetes is a lifestyle disease which can cause many complications and organ-related disorders. The aim of the study was to analyze selected aspects of preparing patients with diabetes for self-care.MethodsThe study group consisted of 190 people diagnosed with type 1 and type 2 diabetes, including 101 women and 89 men. The mean age of the respondents was 42.2 ± 13.4 years. The study was conducted using an anonymous self-designed questionnaire containing 50 questions.ResultsAmong the respondents, 23.2% did not control their glucose levels at home. The respondents most often measured glucose once a day (33.6%) or three times a day (26.7%). 64.7% of the respondents declared that they kept a self-monitoring diary. The knowledge of the symptoms of hypoglycemia and the ability to properly manage it was declared by 64.8% of the respondents. 52.1% of the patients did not undertake any activity lasting more than 30 minutes at least 3 times a week. 75.2% described their condition as very good and good. Independent participation in therapy, i.e. taking hypoglycemic drugs or insulin, was declared by 63.7% of the respondents.ConclusionsDespite undergoing therapeutic education, the study population diagnosed with diabetes still show deficiencies in terms of awareness of proper health behaviors. Objective results showed that the patients had insufficient knowledge and skills in terms of self-care and self-observation, blood glucose and blood pressure measurements, physical activity, diet therapy and adherence to pharmacotherapy recommendations. Despite the good general preparation for self-care as declared by the respondents, these patients require further systematic, individual educational activities.Study implicationsThe results of the present study have implications for nursing practice, patient therapeutic education, and the functioning of the public health and healthcare systems. The number of diabetic patients is constantly increasing. Patients require coordinated care and individualized therapeutic education in order to be prepared for self-care and self-management, thus reducing the risk of complications. Delaying the occurrence of potential complications provides patients with a chance to live an active private and professional life, and protects the health care system from carrying the cost burden of expensive highly specialized services.

Abstract
Menarcheal age in adolescent girls marks an important health concern in women's biology. The timing of menarche is an important determinant of Population size, Reproductive health and is an important factor of Health planning. The paper aimed to find the current mean age at menarche in India and its Nutritional association with micronutrients (given the role of government schemes and services). To fining out about the same the Menarcheal age group of (10-19 years) in India are examined. Binary logistic regression model is used to to estimate the association in the Menarcheal age among the Adolescent using the Comprehensive National Nutritional Survey. The mean age at menarche among adolescents stands at 9.07 years (95% C.I.: 8.990,9.166), including the non menstruating girls within the concerned age group,the mean age was 12.815 years (95% C.I.: 12.837,12.793). Girls with anemia are more likely to have their menarche 0.364 years higher than girls who are non amenic. The mean age at menarche is 0.72 years more likely to occur among those who have multivitamin tables/ syrup. The study concludes that over the time the age at menarche has declined rapidly with economic growth, urbanisation, Improvements in the Nutritional intake ( addition of Micronutrients also seen a contributing factor). The area of concern with regard to Micronutrients supplementation is that, it is done so to provide proper nutritional factors but on the other hand is also causing early Mnearche that most of the Health scientists warned and seen it as a cause for ovarian, breat cancers and other diseases amongst girls in future. Hence its imprtant to keep a proper check on the dietary intake among girls at early stages of life.

Published: December 2021

Abstract
This paper investigates the novel soliton solutions of the coupled fractional system of the resonant Davey-Stewartson equations. The fractional derivatives are considered in terms of conformable sense. Accordingly, we utilize a complex traveling wave transformation to reduce the proposed system to an integer-order system of ordinary differential equations. The phase portrait and the equilibria of the obtained integer-order ordinary differential system will be studied. Using suitable mathematical assumptions, the new types of bright, singular, and dark soliton solutions are derived and established in view of the hyperbolic, trigonometric, and rational functions of the governing system. To achieve this, illustrative examples of the fractional Davey-Stewartson system are provided to demonstrate the feasibility and reliability of the procedure used in this study. The trajectory solutions of the traveling waves are shown explicitly and graphically. The effect of conformable derivatives on behavior of acquired solutions for different fractional orders is also discussed. By comparing the proposed method with the other existing methods, the results show that the execute of this method is concise, simple, and straightforward. The results are useful for obtaining and explaining some new soliton phenomena.

Abstract
Background: Hepatocellular carcinoma (HCC) is one of the most common causes of cancer-related deaths. Recent studies have demonstrated that deregulation of long noncoding RNAs (lncRNAs), such as abnormal DNA methylation of promoter, is strongly associated with development and progression of diverse malignant tumors. This study investigated the mechanisms and changes in DNA methylation levels of promoter regions of HCC-specific lncRNAs, and alterations of downstream target genes.Methods: LncRNA expression profile data of 8 human HCC tissues and matched normal tissues were obtained. LncRNAs with aberrant methylation were identified through DNA methylation microarray. The biological functions of the lncRNAs were investigated through targeted knockdown of lncRNA-SCARF1 in vitro and in vivo. Furthermore, the downstream targets of lncRNA-SCARF1 were identified through ChIRP-MS.Results: LncRNA-SCARF1 was significantly down-regulated in HCC samples. Hypermethylation in the promoter of lnc-SCARF1 induced its down-regulation in HCC. Over-expression of lnc-SCARF1 inhibited the tumor proliferation and migration ability of HCC cells in vitro and in vivo. Furthermore, CUL9 was found to be a potential downstream target of lncRNA-SCARF1.Conclusion: LncRNA-SCARF1 regulates HCC progression by interacting with CUL9 and may serve as a prognostic biomarker or an effective therapeutic target in HCC.
