In Nigeria, rural inhabitants often resort to herbal remedies and dietary control for the treatment and management of various forms of diabetes mellitus. This study was conducted to provide the rationale for the use of Psidium guajava leaves as a potent traditional anti-diabetic remedy. The crude leaf extracts of n-hexane, methanol, and ethyl acetate of Psidium guajava were separately prepared by cold maceration. Then, ethyl acetate crude extract of Psidium guajava leaves was fractionated by column chromatography to yield ethyl acetate bulked fractions: EF-I (1-75), EF-II (76-150), and EF-III (151-250). The n-hexane, ethyl acetate, and methanol crude leaf extracts and ethyl acetate bulked fractions (EF-I, EF-II and EF-III) were evaluated for anti-diabetic activity in alloxan-induced diabetic mice. The blood sugar levels of treated and untreated alloxan-induced diabetic mice were assayed as indices of anti-diabetic effect. The phytochemical constituents of both crude extracts and ethyl acetate fractions of Psidium guajava leaves and the mean lethal dose (LD50) of ethyl acetate crude leaf extract of Psidium guajava were determined. The mean lethal dose (LD50) of ethyl acetate crude leaf extract was calculated to be 1500mg/kg b.w. The results indicated that oral administration of ethyl acetate, n-hexane, methanol crude extracts, and ethyl acetate bulked fractions of Psidium guajava leaves at a dose of 100mg/kg b.w on treated groups exhibited much significant[p<0.001, p<0.01and p<0.05]anti-hyperglyceamic effect by ameliorating high blood sugar levels of alloxan-induced diabetic treated mice, while EF-II and EF-III showed non-significant[p>0.05] anti-hyperglyceamic activity for the reduction in blood sugar levels compared with the negative and positive control groups. The anti-diabetic potency of the crude leaf extracts and ethyl acetate fractions were in the order; EC>HC>MC>EF-I>EF-II>EF-III. The results of phytochemical screening of the crude extracts and ethyl acetate bulked fractions showed the presence of tannins, flavonoids, saponins, alkaloids, terpenoids, glycosides, and steroids while reducing sugar was absent. The results from this study gives credence to the use of Psidium guajava as an anti-diabetic agent in the management of diabetes mellitus.
A new conceptual model for adiabatic fog
Authors: Toledo Felipe , Haeffelin Martial , Wærsted Eivind , Dupont Jean-Charles

Abstract. Visibility reduction caused by fog can be hazardous for human activities, especially for the transport sector. Previous studies show that this problem could be mitigated by improving nowcasting of fog dissipation. To address this issue, we propose a new paradigm which could potentially improve our understanding of the life cycle of adiabatic continental fogs and of the conditions that must take place for fog dissipation. For this purpose, adiabatic fog is defined as a layer filled with suspended liquid water droplets, extending from an upper boundary all the way down to the surface, with a saturated adiabatic temperature profile. In this layer, the liquid water path (LWP) must exceed a critical value: the critical liquid water path (CLWP). When the LWP is less than the CLWP, the amount of fog liquid water is not sufficient to extend all the way down to the surface, leading to a surface horizontal visibility greater than 1 km. Conversely, when the LWP exceeds the CLWP, the amount of cloud water is enough to reach the surface, inducing a horizontal visibility of less than 1 km. The excess water with respect to the critical value is defined as the reservoir liquid water path (RLWP). The new fog paradigm is formulated as a conceptual model that relates the liquid water path of adiabatic fog with its thickness and surface liquid water content and allows the critical and reservoir liquid water paths to be computed. Both variables can be tracked in real time using vertical profiling measurements, enabling a real-time diagnostic of fog status. The conceptual model is tested using data from 7 years of measurements performed at the SIRTA observatory, combining cloud radar, microwave radiometer, ceilometer, scatterometer, and weather station measurements. In this time period we found 80 fog events with reliable measurements, with 56 of these lasting more than 3 h. The paper presents the conceptual model and its capability to derive the LWP from the fog top height and surface horizontal visibility with an uncertainty of 10.5 g m−2. The impact of fog liquid water path and fog top height variations on fog life cycle (formation to dissipation) is presented based on four case studies and statistics derived from 56 fog events. Our results, based on measurements and an empirical parametrization for the adiabaticity, validate the applicability of the model. The calculated reservoir liquid water path is consistently positive during the mature phase of fog and starts to decrease quasi-monotonously about 1 h before dissipation, reaching a near-zero value at the time of dissipation. Hence, the reservoir liquid water path and its time derivative could be used as indicators of the life cycle stage, to support nowcasting of fog dissipation.

NEW WELL RESEARCH TECHNOLOGY IS THE KEY TO THE INTEGRATED DEVELOPMENT OF OIL AND GAS FIELDS
Authors: LELYK Bogdan , STELMAKH Valerii 
Published: September 2021

A detailed analysis of the available nuclear methods for well logging was carried out to select an effective technology from the point of view of obtaining true petrophysical data characterizing the formation matrix and fluid saturation at a specific point of time.
The goal of these process is research currently available nuclear technologies designed for the Oil and Gas field formation evaluation and to review results of the implementation of QUAD NeutronTM (product of Roke Technologies Ltd (Canada)) in old wells in Ukraine.
Reviewed are pulsed neutron technologies available from leading International Logging Companies, which are widely used in Ukraine, including the QUAD NeutronTM, to determine primary petrophysical properties and the reservoir saturation characteristics. Certain criteria have been established that signifi cantly impacted quality of the data analysis during interpretation. These included the number of casing strings installed, absence of Open Hole data as input, drill bit size, presence or absence of cement in the annulus and several others. The advantages and disadvantages of each of the systems are shown and effective examples of application with recommendations and test results are provided in this paper.
Since 2009 QUAD NeutronTM was successfully utilized in more than 3000 wells worldwide. The geography of technology application covers such countries as Canada, USA, Russia, Azerbaijan, Malaysia, Colombia, Venezuela, Peru, China, Nigeria, Mexico, Georgia, Thailand, Kazakhstan, and Saudi Arabia. The following list of IOC, NOC and other international E&P companies contains only some of the users of the data provided by QUAD NeutronTM: Shell, Lukoil, Petronas, Repsol, Cenovus, Talisman, Murphy, Rosne] .
«GEO-DELTA-KB» LLC has exclusive rights to QUAD NeutronTM technology on the territory of Ukraine since 2018. Equipment has been used to provide valuable formation evaluation data to such clients as Ukrgasvydobuvannya, Ukrna] a and other domestic companies in the Western and Eastern regions. Data gave been acquired in dozens of old Oil and Gas wells. The obtained results demonstrate the high efficiency of the technology application, especially when making decisions for the reactivation of old wells.
Conducted analysis of existing nuclear logging methods allowed selection of the most effective technology as compared under similar conditions. The data obtained as a result of interpretation, together with an understanding of the processes occurring in the wells, contributed to providing reliable information for making informed decisions. The most eff ective application of the QUAD NeutronTM technology in Ukraine appears to be for the reevaluation of old wells with complex design (up to 4 strings of casing) to identify missing pay zones, assess the potential of existing reservoirs, determine the presence or absence of cement in the annulus, waterfl ooding zones, etc. The technology can also be successfully used for evaluating active wells and in openhole wellbores.

Integrated management of municipal solid waste seeks sustainability under the premises of environmental protection, health promotion, and economic development. In this context, this article proposes actions and policy tools for local governments to improve quality and governance in waste management. A set of 23 actions is proposed based on existing conceptual models and available legislation. The results are presented in three levels as follows: planning of the administrative and operational structure, waste management, and performance evaluation. The results showed that the proposed actions need to be implemented through policy tools, such as municipal legislation, social communication, normative instructions, and technical studies. The applicability of the proposed methodology, which might be replicated in any municipality to increase the efficiency of the waste management system, was positively evaluated in a medium-sized Brazilian city, which presented an overall attendance level of 52%.

Published: September 2021

Es bien sabido que las formas de tratamiento pronominales varían según los lugares donde se emplean. Nicaragua es considerada plenamente voseante, sin embargo, el uso del vos se da de acuerdo a los parámetros simétricos y asimétricos establecidos por Brown y Gilman (1960). La presente investigación trata de las formas de tratamiento pronominales vos, tú y usted empleadas por los habitantes del barrio José Benito Escobar de Mateare, municipio del departamento de Managua, cuya finalidad es analizar dialectológicamente el tratamiento tanto en relaciones simétricas, asimétricas y de distanciamiento, también en situaciones pragmáticas. De la misma manera, se estudió el tratamiento desde la perspectiva de las actitudes lingüísticas vinculadas con estos pronombres de la segunda persona del singular. Para ello, se aplicaron encuestas a un total de 24 informantes. Entre los resultados más relevantes destacamos que la edad es determinante para decidir el tratamiento hacia el interlocutor, ya que, si este es menor que el emisor, lo más seguro es que se lo trate de vos, pero si es mayor se lo tratará de usted. Otra conclusión importante es que el usted es el tratamiento dominante cuando se acaba de conocer a una persona, pero a medida que la confianza crece, aumentan las posibilidades de un cambio de pronombres a favor de vos. Además, esta investigación corroboró que el tuteo sigue siendo prácticamente inexistente en Nicaragua, principalmente en la lengua hablada.
The procedure for concluding a lease of property for state needs of the penitentiary system
Authors: Шоргина Елена Васильевна 
Published: September 2021

В статье рассматриваются вопросы, связанные с особым порядком заключения договора аренды имущества для государственных нужд уголовно-исполнительной системы. Отмечается сложность процедуры согласования договоров по распоряжению казенным имуществом, находящимся в оперативном управлении. В то же время учреждения УИС в полной мере обладают гражданской правоспособностью и дееспособностью, однако в силу специфики своей деятельности они имеют специальную правоспособность, которая ограничена учредителем. Автор обращает внимание, что заключать договор аренды казенное учреждение может только посредством проведения закупки в соответствии с действующим законодательством. Особенность в определении субъектов арендных правоотношений заключается в том, что учреждение может быть как арендодателем, так и арендатором. Также в статье поднимается вопрос, является ли Федеральное агентство по управлению государственным имуществом стороной договора, и какова его роль при заключении указанных договоров.
The article deals with issues related to the special procedure for concluding a lease agreement for property for state needs of the penitentiary system. The complexity of the procedure for agreeing on contracts for the disposal of public property under operational management is noted. At the same time, it is said that the institutions of the penal system fully possess civil legal capacity and legal capacity. However, due to the nature of their activities, they have special legal capacity, which is limited by the founder. The author points out that a government agency can only enter into a lease agreement through procurement in accordance with applicable law. Features in the definition of subjects of lease relations lies in the fact that the institution can be both a landlord and tenant. The article also raises the question of whether the Federal Agency for State Property Management is a party to the contract and what is its role in concluding these contracts.
