Introduction: Penile fracture is a rare surgical emergency. It usually occurs as a single rupture of the tunica albuginea in one of the two corpora cavernosa; a rupture of both masses is an uncommon finding. We conducted this study to determine the etiology, clinical presentation and to review the causes and management of penile fracture.
Methods: The retrospective study was carried out on 17 patients, admitted in the department of Urosurgery from January 2017 to December 2020 with penile fracture in a tertiary care teaching hospital in Kathmandu. Patient demographic profile, etiology, clinical presentation, time interval from injury to presentation, investigation done, treatment given and intraoperative findings were analyzed.
Results: The main cause of penile fractures was sexual intercourse (82.35%) followed by manual manipulation (17.65%). Crackling sound (100%) followed by penile hematoma and pain were the most common presenting symptoms among the patients. Surgical exploration and repair of injury was done in all patients.
Conclusion: Most of the time diagnosis of penile fracture can be made reliably by history and physical examination. Early surgical intervention is associated with a good outcome, regardless of the timing of presentation.

Дробильно-сортувальні комплекси з переробки технологічних є основними елементами в транспортно-виробничих системах рециклінгу відходів металургійних підприємств. Дробильно-сортувальні комплекси у даному дослідженні розглядаються як спеціалізовані комплекси металургійних шлаків сталеплавильного виробництва. В основу функціонування дробильно-сортувальних комплексів покладено метод магнітної сепарації, з застосуванням примусового очищення лому в спеціальних дробильних пристроях. Функціонування дробильно-сортувальних пристроїв жорстко пов’язано з технологією основного виробництва металургійного підприємства. Не вітчизняних металургійних підприємствах застосовують саме цей вид технологічних переробки відходів, тому що він дозволяє розділяти виробничі шлаки на різні види фракцій, а також забезпечує контроль якісних показників продуктів переробки відходів, а саме витяг металомісткої сировини.
Однак треба брати до уваги, той факт, що дробильно-сортувальний комплекс якщо деякий час нема автотранспорту не зможе може призупинити процес переробки сировини, що призведе до зупинки роботи комплексу і, як наслідок, зупинки всього технологічного процесу рециклінгу відходів. В такому випадку необхідно здійснювати зупинку технологічного процесу переробки технологічних відходів, що є неприпустимим. Це може бути пов’язане чи з запізненням автомобілів у зв’язку з затримкою на шляху прямування чи на фронтах завантаження чи з використанням автомобілів нераціональної вантажопідйомності. При використанні автомобілів недостатньої вантажопідйомності дробильно-сортувальний комплекс не встигають завантажувати, тобто кількість сировини, яка завантажується самоскидами до приймального бункеру комплексу є недостатньою для його переробної спроможності.
Було проведено хронометраж завантаження дробильно-сортувального комплексу цеху шлакопереробки металургійного підприємства на протязі однієї доби, а саме двох робочих змін. Отримані в процесі дослідження характеристики вказують на те, що досліджуваний параметр можна вважати випадковою величиною.

Authors: Stepova O.V. , Kornishyna A. V. 
Published: December 2021

The studies were conducted in accordance with the requirements set out in the Declaration of the European Union "On Environmental Noise Assessment" and are closely related to finding solutions of the problems set out in the Law of Ukraine "On Ensuring Sanitary and Epidemic Welfare of the Population".
The paper presents experimental and calculation studies on the assessment of noise pollution in the central part of Poltava. The results of such studies confirmed the hypothesis of exceeding the normative values of noise levels within some sections of the streets and directly at the intersections. It was found that the main causes of noise pollution include high intensity of public and light commercial transport means, large number of intersections and stops, poor road surface, as well as lack of acoustic protection, including lack of landscaping along roadsides. The research visually characterizes and investigates the boundaries of acoustic pollution areas distribution. Exceedence of the noise pollution normative values extends to the distance of up to 150 m from the experimental study points.
The study determines the number of residents of the district who fall into high noise load areas and estimates the magnitude of risks to health of the citizens living within such areas. Experimental studies established a link between a negative impact of external noise generated by urban vehicles and urban residents' health state that requires hygienic research with application of WHO-recommended risk analysis methodology. It was found that almost 5,000 people from the study area spend most of their lives in the neighbourhoods where the noise level exceeds the permissible value of 55 dBA. Almost 2,000 of them live in the houses where penetrating noise exceeds the value of 40 dBA.
Based on the results of theoretical provisions and conclusions, certain practical recommendations for management of noise pollution risks in the urban area were developed.

Published: December 2021

The main preconditions emergence of an environmental crisis in the country due to surface water pollution include irrational use of water resources in violation of the environmental requirements, discharge of untreated and insufficiently treated industrial and municipal wastewater into water bodies and inflow of polluting substances from agricultural lands as a result of surface water drainage. The whole set of considered factors leads to depletion and pollution of surface water of Ukraine, reduction of their self-cleaning capacity, degradation, impoverishment and collapse of aquatic ecosystems.
Excessive content of heavy metal ions in surface water has a negative impact on the environment, causing acute and chronic diseases. Ingress of such pollutants into surface water is almost entirely due to anthropogenic economic activity. Wastewater from chemical, ferrous and nonferrous metallurgy brings a great amount of such pollutants.
Among various methods used for removing heavy metal ions from aqueous media, sorption methods remain one of the most effective and popular, mainly due to the fact that they ensure a high degree of purification at relatively low costs. Along with the adsorbents traditionally involved in these processes, a number of studies and practical implementations with use of natural dispersed minerals as adsorbents were conducted lately.
The research aims at studying the sorption capacity and efficiency of natural and modified sorbent such as bentonite clay for purification of aqueous solutions containing heavy metal ions in the form of dissolved compounds and justifying its potential application.
It studies the efficiency of wastewater treatment aimed at removing heavy metal ions by the natural clay sorbent of bentonite clays of the Cherkaskyi Deposit (Dashukovskyi deposit).
The paper presents a technique for modification of bentonite clay in order to increase its adsorption capacity for heavy metal ions using the following three methods: physical (thermal), chemical (processing with application of Iron(III) chloride solution) and combined (thermal processing of the original sorbent followed by processing with application of Iron(III) chloride solution).
It has been experimentally proved that a natural sorbent modified via thermal and chemical processing is characterized by a high absorption capacity to heavy metal ions contained in water solutions, in particular to chromium(VI) ions, copper(II) ions and aluminum(III) ions with the purification degree ranging from 5% to 83%. The highest adsorption rate, 83%, is demonstrated by the combined method of bentonite clay modification, therefore proving the effectiveness of application of environmentally friendly natural sorbents for wastewater treatment processes aimed at removing heavy metal ions. The paper indicates the advantages of wastewater treatment sorption methods allowing removal of pollutants of different origin and any concentration.
Existence and asymptotics of ground states to the nonlinear Dirac equation with Coulomb potential
Authors: Wang Tianfang , Zhang Wen , Zhang Jian 
Published: December 2021

In this paper we study the Dirac equation with Coulomb potential [Formula: see text] where a is a positive constant, μ is a positive parameter, [Formula: see text], [Formula: see text] and β are [Formula: see text] Pauli–Dirac matrices. The Dirac operator is unbounded from below and above so the associate energy functional is strongly indefinite. Under some suitable conditions, we prove that the problem possesses a ground state solution which is exponentially decay, and the least energy has continuous dependence about μ. Moreover, we are able to obtain the asymptotic property of ground state solution as [Formula: see text], this result can characterize some relationship of the above problem between [Formula: see text] and [Formula: see text].

BACKGROUND: Carmustine is a chemotherapeutic agent that is mainly used in the treatment of glioblastoma and can cause toxic effects on various organs, including the liver. The white mulberry extract has anti-apoptotic and anti-oxidant effects. OBJECTIVE: The study aimed at investigating the effects of the dried white mulberry extract on the pathology, apoptosis, and oxidative stress in the liver, as well as the levels of serum adenosine deaminase, glutathione peroxidase, superoxide dismutase, ceruloplasmin, paraoxonase, and malondialdehyde in carmustine-administrated rats. METHODS: Forty-two rats divided into six groups were used in this study. BCNU was administrated intraperitoneally (IP) (5 mg/kg body weight (BW)/week) for 10 weeks to the BCNU and BCNU-DWME groups. DWME was administered (600 mg/kg-BW by oral gavage) daily for 10 weeks to the DWME and BCNU-DWME groups. After the experimental procedure, histopathological, immunohistochemical, and biochemical analyses were performed. RESULTS: Carmustine caused biliary hyperplasia at a dose of 5 mg/kg. However, the mulberry extract was not effective in alleviating this pathology. Furthermore, the administration of carmustine induced apoptosis in hepatocytes, and the mulberry extract had an anti-apoptotic effect. Carmustine increased the 8-OHdG activity in the liver, and dried mulberry extract ameliorated this activity. Although there was no significant difference in the serum oxidative stress parameters between the groups, carmustine significantly increased the adenosine deaminase activity during the recovery period, while mulberry extracts partially ameliorated these effects in the recovery period. CONCLUSIONS: Dried white mulberry extract has anti-apoptotic and anti-oxidative effects against carmustine-induced toxicity.

The article covers the establishment and development of specialized hotels for animals, the study of prospects for the introduction of hotels of this type in Ukraine. Zoo hotels have appeared as an alternative to keeping animals in hospitals at veterinary clinics. By the way, they provide such services to them. Small boxes that limit the extra mobility of the pet - a good option after surgery during the rehabilitation period, but not for a perfectly healthy animal. Hotel for animals - a specialized room that meets the established requirements for the accommodation of animals temporarily transferred by their owners for maintenance [azar].
The world of pets is very interesting. Observing and studying it, and people are fascinated not only by amazement and new discoveries, they care about animals and kindness, and love, and indulgence. Knowing animals, man knows himself.
Throughout history, pets have played a key role in human life, and have been seen primarily as suppliers of food, clothing, transportation, and time as an object of religious worship. Although animals around the world still use these traditional uses, the role of many animals in society has changed. Yes, there is a sharp increase in the number of animals that are supported and maintained as abilities for pleasure.

Abstract
The aim of the study was to evaluate the QuantiFERON-TB Gold Plus (QFT-Plus) test usability in the identification of latent tuberculosis infection (LTBI) in children and the determination of features associated with tuberculin skin test (TST) and QFT-Plus-positive results concerning LTBI. Two-hundred thirteen children aged 1–14 were screened for LTBI due to household contact with TB, suspected TB, or were qualified for biological therapy. The objective of this study was to evaluate the QFT-Plus affectivity as a diagnostic test in the absence of a gold standard (GS) test for the diagnosis of LTBI. The children were diagnosed with QFT-Plus, TST, and culture of TB. The QFT-Plus results were analyzed depending on the children’s age, TST size, and type. In children aged 1–4, the positive predictive value of QFT-Plus was 1, the negative predictive value was 0.94, QFT-Plus sensitivity was 75%, and specificity was 100%. It was observed that in children aged 5–14 years, the level of agreement decreased to the substantial, i.e., 87.2%. Moreover, the negative predictive value was 0.83. QFT-Plus sensitivity was 64%, and specificity was 100%. Statistical analysis of QFT-Plus and TST results showed substantial and almost perfect agreements. Our study suggests that QFT-Plus is helpful in a pediatric practice showing good sensitivity and specificity for LTBI. The BCG vaccine, infections, and concomitant morbidities do not affect QFT-Plus results.
