В статье рассказывается о том, как на кафедре «Организация строительства и управления недвижимостью» (ОСУН) МГСУ было положено начало еще одной, новой уникальной традиции — организации зарубежной производственной практики студентов. В соответствии с достигнутыми договоренностями прошла зарубежная стажировка студентов кафедры ОСУН на АЭС «Аккую» в Турецкой Республике. Государственная корпорация по атомной энергии «Росатом» — многопрофильный холдинг, объединяющий активы в энергетике, машиностроении, строительстве. АЭС «Аккую» — первая атомная электростанция в Турецкой Республике. Проект первой турецкой АЭС включает в себя четыре энергоблока с реакторами российского дизайна ВВЭР-1200. Сооружение АЭС «Аккую» — первый проект в мировой атомной отрасли, реализуемый по модели Build-Own-Operate. Кафедра ОСУН осуществляет свою деятельность на протяжении более 90 лет, имеет свою историю и устоявшиеся традиции. Идя в ногу со временем, принимая во внимание нынешние инновационные тренды и вызовы в сфере строительства, экономики, образования, на кафедре была организована зарубежная стажировка студентов. С какими же трудностями они столкнулись и почему этот «пилотный проект» является очень ценным, знаковым опытом не только для кафедры, но и для НИУ МГСУ в целом. По итогам совместного проекта можно отметить, что поставленные цели и задачи решены. Стороны остались довольны результатами, отметили важность такого формата сотрудничества и запланировали дальнейшие взаимоотношения.
Экологический менеджмент в строительстве: тенденции, уровни управления, показатели
Authors: Симионов Радомир Юрьевич , Кирпиченков Андрей Андреевич
Published: October 2024

Сохранение окружающей природной среды во многом зависит от повышения экологической ответственности строительных организаций. Статистические данные показывают, что последние годы характеризуются ростом объемов работ по виду экономической деятельности «Строительство», что требует организационных, правовых, экономических, технологических и технических мер, реализуемых на государственном, отраслевом уровнях и в системе управления строительными организациями, направленных на рациональное природопользование. Эти меры относятся не только к стадии строительства объектов, но и периоду эксплуатации объектов недвижимости, что обусловлено значительной ресурсоемкостью объектов недвижимости как в процессе строительства, так и эксплуатации в течение всего жизненного цикла. Исследование проблемы приводит к выводу, что формировать механизм экологического менеджмента следует с учетом специфики строительной деятельности, обеспечивая безопасность на стадии при проектировании объектов, организации строительной площадки, освоении территории застройки, внедрении процессных инноваций в строительстве. В управлении ресурсосбережением кроме инвестиционной стоимости объекта необходимо управлять затратами на эксплуатацию объекта, которые составляют 75 % затрат владения объектом. Принципы экологической эффективности должны находить отражение в показателях оценки инвестиционных проектов. Ответственное с позиций экологии инвестирование может стать одним из трендов реализации национальных проектов, поскольку цели национальных проектов соответствуют концепции устойчивого развития и сбалансированности экономических, социальных и экологических факторов. Выявлены барьеры препятствий ESG-инвестированию в отечественной экономике, в частности недооценка влияния названных факторов на долгосрочные финансовые показатели самих организаций. Для организации системы экологического менеджмента в строительных организациях необходимо формирование системы показателей (индикаторов устойчивости), наличие которой позволит моделировать экологический профиль организации. Экологический профиль позволяет установить баланс внешних запросов и реальных возможностей самой организации. Это требует не только наличия сбалансированной системы экологических показателей организации, но и эталонных значений показателей, обеспечивающих организации повышение конкурентоспособности на рынке подрядных работ.
Evaluating Schizochytrium Supplementation on Growth Performance and Skin Colouration in Electric Yellow Cichlids (Labidochromis caeruleus)
Authors: Karataş Boran , Kaya Doğukan
Published: October 2024

In this study, the effects of Schizochytrium supplementation to feed on growth and skin colouration in electric yellow cichlid (Labidochromis caeruleus) were investigated. Fish (1.93 ± 0.23 initial weight) were fed with commercial fish feed (C) and commercial fish feed supplemented with 0.5% (D05) and 1% (D1) Schizochytrium for 60 days. The D05 and D1 groups displayed the highest FW, WG, and SGR values, with similarly favourable FCR levels compared to the C group. Among the groups receiving Schizochytrium-supplemented feeds, no statistically significant differences in growth performance were observed. The D1 group exhibited statistically significant differences from the C and D05 groups concerning L* and Hue values (p < 0.05). The a* value in the D05 and D1 groups showed a statistically significant difference compared to the C group. However, there were no statistically significant differences in the b* and Ch values among all groups. To conclude, the inclusion of Schizochytrium as a dietary supplement markedly promoted growth performance and facilitated the attainment of marketable size in electric yellow cichlids. Additionally, although the enhancement in skin colouration resulting from the addition of 0.5% Schizochytrium to the feed did not reach statistical significance, it hints at a promising advantage that could enhance the aesthetic allure and market value of the fish.

Authors: Katabba Yunus Iman , Estefani Kezia
Published: October 2024

Palm oil is an agricultural commodity that has an important role in the global economy. Palm oil is obtained from the fruit of the oil palm tree (Elaeis guineensis) which grows in tropical regions, especially in countries such as Indonesia, Malaysia, Thailand and several West African countries. Palm oil has a variety of uses in the food, cosmetics and fuel industries, making it one of the most traded commodities in the world. Palm oil price fluctuations have a significant influence on the economy in producing and consuming countries. Therefore, a time series analysis is needed that can predict fluctuations caused by certain conditions. This analysis is carrying out nonlinear analysis using the SETAR (Self Exciting Threshold Autoregressive) method on palm oil prices to obtain a prediction model and prediction results for palm oil prices. The SETAR model is a special case part of the Threshold Autoregressive (TAR) model. The SETAR model threshold is a lag value of the series itself or the endogenous variable. Analysis carried out using the SETAR method produces a SETAR (3,1,1) model with threshold (r) = 0.01626070 where the fit value approaches the actual data value and the predicted value follows the actual data pattern

Investigating the political and regulatory context of corruption and foreign direct investment in post-Soviet countries
Authors: Bokayev Baurzhan , Zagrebin Alexandr , Davletbayeva Zhuldyz , Nauryzbek Madina
Published: October 2024

This article considers the ongoing academic debate surrounding the impact of corruption on investments (Lestari et al., 2022). The aim of the study is to analyze the relationship between corruption and foreign direct investment (FDI) inflow in post-Soviet countries and to examine anti-corruption-related factors influencing investment activity. The investigation employs quantitative and qualitative research methods. The authors analyze secondary data from the World Bank (WB) and Transparency International (TI), examining the dynamics of FDI as well as the corruption perceptions index (CPI) for 15 post-Soviet countries from 2013 to 2022. Upon computing Pearson’s correlation coefficients, no significant association between these two indicators was found. In this regard, the authors assumed that the inelastic demand for specific resources in developing nations outweighs the discouraging effect of corruption. These observations correspond to the findings of Abdella et al. (2018). Furthermore, instances of notable fluctuations in CPI rankings accompanied by significant FDI growth were examined, with a focus on the associated political and regulatory context. To explore this, the authors analyze “gray literature” from 2013 to 2022, highlighting significant events within countries. Findings establish a cause-and-effect relationship between these events, the changes in CPI, and FDI.

Authors: Rey Rubiano Adrianan Margarita , Reyes Gustavo Adolfo , Mendoza de Molano Belén , Vergara Cabra Cathalina , Pérez Riveros Erika D , Robayo Juan Carlos , Vásquez Roldán Mariana , Sierra Arango Fernando
Published: October 2024

Objetivo: el coronavirus del síndrome respiratorio agudo grave de tipo 2 (SARS-CoV-2) causa un gran espectro de síntomas, dentro de los que se incluyen manifestaciones gastrointestinales como náuseas, vómito, diarrea y dolor abdominal. El objetivo del presente estudio fue evaluar si la presencia o no de dichos síntomas gastrointestinales podía estar relacionada con una progresión más grave de la enfermedad, entendida como muerte, necesidad de manejo en unidad de cuidados intensivos, ventilación mecánica o coinfección bacteriana.
Pacientes y métodos: se realizó un estudio observacional analítico de tipo cohorte con pacientes con covid-19 confirmado con síntomas gastrointestinales y un grupo comparador sin síntomas gastrointestinales. Los pacientes incluidos debían ser mayores de 18 años, que acudieran por sintomatología sugestiva de covid-19 y que se les confirmara el diagnóstico mediante una prueba de reacción en cadena de la polimerasa.
Resultados: se analizó a un total de 414 pacientes que cumplieron con los criterios de selección y se encontró que la mortalidad solo está influenciada por la edad, mientras que la ventilación mecánica y la necesidad de manejo en la unidad de cuidados intensivos están relacionadas con el perfil de función hepática. Sin embargo, no se encontró ninguna diferencia en cuanto a la gravedad con respecto a los pacientes que sí presentaron síntomas gastrointestinales frente a los que no tenían síntomas.
Conclusiones: los síntomas gastrointestinales de manera individual no representan un riesgo de progresión de la enfermedad por SARS-CoV-2; sin embargo, sí se debería incluir dentro de la valoración inicial de estos pacientes los niveles de alanina-aminotransferasa (ALT), aspartato-aminotransferasa (AST) y bilirrubina directa (BD), pues aportan un valor en cuanto al pronóstico según los resultados de nuestro estudio.

Authors: Segovia Javier Mauricio , Osorio Sánchez Sergio Alejandro , Cantor Erick Andrés , Pino Luis Eduardo , Vargas Henry Alexander , Murillo Silva John Alejandro , Triana Iván Camilo , Navas Cardona Valentina
Published: October 2024

El cáncer anal primario representa del 1% al 3% de los cánceres gastrointestinales. La histología más común es el carcinoma escamocelular, con una incidencia de 0,5 a 2 por cada 100.000 personas. El principal factor de riesgo es la infección por el virus del papiloma humano, especialmente los subtipos 16 y 18, que representan del 85% al 93% de los casos.
El tratamiento y el pronóstico dependen del estadio del tumor. Los tumores localizados se pueden tratar con cirugía curativa, pero las etapas localmente avanzadas requieren una combinación de quimioterapia y radiación. Los tumores en estadio avanzado (IIIC y IV) tienen un mal pronóstico incluso con quimioterapia. En los últimos años, la inmunoterapia y las terapias dirigidas son prometedoras para mejorar la supervivencia de los pacientes con enfermedad avanzada, recurrente o difícil de tratar.
Se presenta el caso de una mujer de 69 años con carcinoma escamocelular moderadamente diferenciado (T2N1M0, estadio IIIA) del canal anal que, después del tratamiento con quimiorradioterapia e inhibidores de punto de chequeo y luego de la progresión de la enfermedad, recibió tratamiento con terapia blanco (cetuximab) y logró la remisión completa de la enfermedad y una respuesta mantenida por más de 18 meses.
Este caso destaca los desafíos del tratamiento del cáncer anal avanzado y los beneficios potenciales de la terapia dirigida, especialmente cetuximab, para lograr respuestas a largo plazo. Se necesitan más investigaciones a gran escala para determinar el papel de la terapia blanco y la inmunoterapia en el tratamiento de este cáncer.

Introducción: la calidad de la colonoscopia es un factor determinante en los desenlaces clínicos y depende en gran medida de la limpieza intestinal lograda con una adecuada preparación. El tipo de agente, la adherencia y tolerabilidad son factores que pueden influenciar la calidad de la limpieza y, por ende, los resultados del procedimiento. Con este estudio se busca evaluar cuáles son los motivos que determinan la escogencia del agente para la preparación y su impacto en la calidad de la colonoscopia.
Metodología: estudio observacional de corte transversal con una muestra de 530 pacientes. Agentes evaluados: polietilenglicol (PEG), picosulfato de sodio y sulfato de sodio-potasio-magnesio (sulfato de Na-K-Mg), con sus esquemas de dosis continua y dividida, según el caso. Los motivos para la selección y la tolerabilidad se evaluaron por medio de una encuesta. La limpieza intestinal fue determinada por el endoscopista mediante la escala de Boston.
Resultados: la edad promedio fue de 52,7 años (± 13,4), 60% fueron mujeres. El agente más elegido fue PEG (81,9 %) en el esquema de dosis completa (74,5%). El principal factor determinante fue la disponibilidad del fármaco, con un 42,6%. Se presentaron síntomas indeseables en el 62,6% de los pacientes; sin embargo, el 99,4% lograron una preparación adecuada (Boston ≥6).
Conclusión: el principal factor relacionado con la selección del agente para la preparación intestinal es la disponibilidad. La tolerabilidad objetiva no condiciona diferencias relevantes en la calidad de la limpieza ni el éxito del procedimiento.

Published: October 2024

The valorization of industrial waste streams generated in vast quantities is
becoming an increa-singly prominent priority in line with the principles of
circular economy. One potential avenue for utilizing food industry waste
streams lies in the production of microbial agents with biocontrol and PGP
(plant-growth promotion) properties. Bacillus species, given their broad
spectrum of bioactive metabolites, exhibit significant potential in the
production of such bioagents. The aim of this study was to investigate the
circular economy approach by utilizing whey from dairy industry, meat
processing wastewater and digestate obtained from biogas production using
solid meat industry effluents, as potential bases for media used to
cultivate Bacillus sp. BioSol021 and to investigate their biocontrol
activity against pepper black spot causal agent, Xanthomonas euvesicatoria,
as well as their PGP effects in the pepper seed germination phase. The
highest antimicrobial activity, tested using the disc diffusion method, was
observed in the whey-based cultivation broth sample after 96 hours of
cultivation. Pepper seeds treated with cultivation broth of Bacillus sp.
BioSol021 based on meat industry wastewater exhibited the best results in
terms of germination rate (80%), root length (10.40 mm) and shoot length
(6.20 mm). The results of this study confirm the suitability of whey, meat
industry waste-water, and biogas production digestate as the potential
cultivation media components for producing Bacillus-based biocontrol and PGP
agents for a more sustainable agricultural practice.

Published: October 2024

This study aimed to assess the characteristics of Saharan plants by
analyzing the chemical composition and evaluating the antioxidant and
anti-inflammatory properties of raw extracts from Matthiola livida DC.,
collected from the Oued-Souf region. The primary metabolites analysis
revealed carbo-hydrates as the dominant components, with a concentration of
35.70 ? 0.03 mg/g dry weight. Using the maceration technique, three
unrefined extracts (methanolic, ethanolic, and aqueous) were produced, with
the aqueous extract yielding the highest output at 14.61%. Total polyphenol
content varied from 170.82 to 102.42 mg of GA/g dry extract, and the ethanol
extract had the highest flavonoid content at 97.03 ? 4.14 mg of QE/g dry
extract. The DPPH? test showed the methanolic extract as the most potent
antioxidant, with an IC50 of 153.56 ?g/ml. The ethanolic extract offered the
most protection to human erythrocytes, resulting in only 16.93% hemolysis
at a concentration of 1 mg/ml. It also showed the strongest
anti-inflammatory effects in vitro, with a protein denaturation inhibition
equivalent to 11.29?1.10 mg of diclofenac sodium per milligram of dry
extract. Additionally, IR spectroscopy identified several functional
groups, including hydroxyl (O-H), carbonyl (C=O), and various
carbon-hydrogen bonds (C-H, C=C, C-H). Future research should explore the
clinical applicability of these findings to enhance the therapeutic
potential of Matthiola livida extracts.

Published: October 2024

The microstructure of maraging steel produced by direct metal laser sintering
(DMLS) is influenced by various factors, including parameters of the DMLS
process and post-treating methods. This study investigates the effect of
build orientation on the microstructure and fatigue behaviour of M300
maraging steel manufactured using DMLS. Microstructural characterization was
conducted using light microscopy (LM) and scanning electron microscopy
(SEM). The study also involved analysing fracture surfaces using SEM and
performing fatigue tests on additively manufactured samples. The research
reveals that the presence of inclusions in the specimens has resulted from
trapped powder on the edge of the melted pool or from trapped metal oxides.
These defects, especially when located near the surface of the specimens,
often represent a weak spot and the source of initial cracks.
Optimization method for the overlap rate of laser cladding using a variable fitting function
Authors: Song Boxue , Wang Zisheng
Published: October 2024

The objective of this study is to enhance the overlap rate in the preparation of a cladding layer to achieve a flat cladding surface. A novel optimization method is proposed that employs variable fitting functions—such as the Lorentz peak function, single-phase exponential decay, and Voigt function—to match the cladding layer height information to the overlap rate with higher precision. Utilizing these specific fitting functions allows for a tailored optimization process based on varying material and process conditions. Experimental results using RCF103 alloy demonstrated that our method could improve the overlap rate optimization by up to 15% compared to the traditional techniques, achieving a flatter and more uniform cladding layer.

Authors: Liu Hao , Huang Can , Mo Jinyong , Duan Mantang
Published: October 2024

Recent advances in materials science have shed light on the potential of refractory high-entropy alloys (RHEAs) to improve wear performance across varying temperatures. These alloys offer an optimal balance between strength and ductility, making them ideal for protective coatings. Despite the lightweight properties of Ti-6Al-4 V alloys, they still pose challenges when it comes to wear resistance. This study presents a lightweight coating using RHEAs made of AlCrNbMoV through laser cladding. Notably, the AlCrNbMoV coating exhibits a single-phase BCC structure and completes with diffuse regions enriched in titanium dendrites. In addition, the microhardness of the coating is measured at 792.4 (±6.5) HV0.5, showing a remarkable improvement compared to TC4. The wear rate at 600 °C for the AlCrNbMoV coating is measured at 0.43(±0.026)×10−4mm3/N/m, demonstrating a significant reduction of 91.43% when compared to the wear rate of TC4, which stands at 5.02(±0.081)×10−4mm3/N/m. The wear mechanism undergoes a transition from abrasive wear at room temperature to adhesive wear at 300 °C and then to fatigue wear at 600 °C. The study introduces new possibilities for the application of RHEAs in protective coatings, particularly in high-temperature environments such as aerospace.

Authors: Jiang Na
Published: October 2024

Virtual currencies have transaction characteristics such as decentralization, anonymity and cross-border because of their technical advantages, which make them a new channel for money laundering crimes, i.e., block-chain technology effectively enhances the efficiency of transactions while facilitating the implementation of money laundering crimes. At present, the governance of virtual currency money laundering crime is faced with the dilemma of legal lag, the lack of traditional regulatory model caused by technology and insufficient regulatory resources. In order to solve the problem of virtual currency money laundering crime governance, this paper puts forward the need to: clarify the legal status of virtual currency and through the development of special laws and regulations in order to improve the legal regulation; the establishment of internal anti-money laundering mechanism, strengthen the platform in the real-name system of transactions and transaction records access to the regulatory responsibilities; the construction of cross-sectoral joint early warning platforms, to promote the sharing of information and cooperation; and to strengthen international cooperation, the formation of a joint mechanism to combat the crime. In conclusion, the governance of virtual currency money laundering crime is not a one-day or one-country effort, and requires a variety of measures such as law. It requires coordination and efforts in multiple directions, such as internal regulation and external cooperation, in order to overcome the legal lag, integrate governance resources through a perfect legal regulatory system, a complete regulatory mechanism and adequate international cooperation, and thus effectively curb the crime of virtual currency money laundering and maintain the stability and security of the financial market.

Authors: Bala Zakari Musa
Published: October 2024

The goal of any independent anticorruption agency, wherever it may be located, is to reduce or eliminate the incentives and opportunities that make corrupt activities alluring, thereby enhancing the effectiveness of the ruling government by eliminating elements within the system that may be damaging or corrupt. Achieving these aims requires ensuring that dedicated anticorruption agencies are provided with sufficient personnel and resources, and that additionally their organisational development needs are met. -This paper draws upon unique access to interviews with 20 senior officials employed in the dedicated anti-corruption agencies fighting corruption in Nigeria and access to 20 case files relating to prosecutions by the Independent Corrupt Practices and other related offences Commission (ICPC). The article asserts that the first step in fighting corruption must be to renew focus on economic development and welfare. These terms cover a range of government strategies designed to ensure the wellbeing of the citizenry, such as healthcare, education, vocational training, public housing and public transportation. It argues that until these support structures are easily accessible to the citizens, referred to within the article as taking care of “favourable policy context”, countering corruption in Nigeria, will remain a vicious circle.
