Tanah berperan di setiap pekerjaan teknik sipil. Hampir semua bangunan dibuat di atas atau di bawah permukaan tanah. Tanah lempung yang memiliki perilaku lunak, namun tidak juga cair. Kondisi tanah ini dijadikan tanah dasar dari sebuah bangunan struktur sangat tidak kondusif, karena tanah lempung dipengaruhi oleh kadar air yang terkandung pada tanah. Pemanfaatan tanah dengan sifat demikian menyebabkan kegagalan pada kontruksi. metode yang digunakan yaitu pada penelitian ini stabilisasi, dengan menambahkan 2% 4% 6% bubuk arang kayu, dengan peremeraman 3 hari dan 7 hari, yang ditinjau pada penelitian ini adalah nilai CBR dan Indeks plastisitas, karena bubuk arang kayu dapat memperbaiki sirkulasi air dan udara, serta dapat mengikat karbon, dan dapat mengurangi kembang susut tanah karena sifatny mereduksi indeks plastisitas tanah. Dari hasil penelitian yang dilakukan di laboratorium sifat fisik tanah asli didapatakan AASHTO sebagai tanah berlempung kelompok A-6 (6) dan USCS sebagai tanah lempung anorganik dengan plastisitas rendah sampai dengan sedang, tanah termasuk kelompok CL. Nilai Indeks Plastisitas menurun setelah di tambahkan bubuk arang kayu. Analisis data menggunakan analisis varian menyatakan bahwa penambahan bubuk arang kayu memberikan pengaruh terhadap nilai CBR perbaikan tanah dasar.

Bishop Sylvester Malevansky as a Theology Lecturer: An Archival Research of Memoirs of Kiev Theological Academy Graduates
Authors: Бурега Владимир Викторович 
Published: August 2021

Статья посвящена ректору и многолетнему профессору Киевской духовной академии (КДА) епископу Сильвестру (Малеванскому) (1828-1908). В течение более сорока лет он преподавал в КДА богословские дисциплины (сначала обличительное богословие, затем - догматическое). Его перу принадлежит ряд публикаций в области богословия, из которых наиболее важным является «Опыт православного догматического богословия (с историческим изложением догматов)» (в пяти томах). Епископ Сильвестр использовал в своём курсе догматики исторический метод, который предполагал изложение вероучения в его историческом развитии. Этот подход принципиально отличает догматику епископа Сильвестра от «Православно-догматического богословия» митрополита Макария (Булгакова). В статье реконструируется облик епископа Сильвестра как преподавателя богословских дисциплин в КДА. Статья подготовлена на основе архивных материалов. В частности, в Институте рукописей Национальной библиотеки Украины им. В. И. Вернадского сохранился корпус неизданных воспоминаний о епископе Сильвестре выпускников КДА разных лет. В этих мемуарах значительное внимание уделено педагогической деятельности епископа Сильвестра. Особенностью лекций епископа Сильвестра была постоянная полемика с современными ему течениями в западной богословской и философской мысли. В основу его лекций (также как и печатного курса догматики) был положен исторический метод. Специально мемуаристы отмечают глубокое воодушевление, с которым читал лекции епископ Сильвестр, стремясь приблизить возвышенные богооткровенные истины не только к уму, но и к сердцу студентов.
The article tells about the rector and professor of the Kiev Theological Academy (KThA) Bishop Sylvester Malevansky (1828-1908), who was a lecturer on comparative Christian theology and dogmatic theology at KThA for over 40 years. He wrote several scholarly works including the five-volume Essay of the Orthodox Dogmatic Theology with an Historical Exposition of the Dogmas. In his teaching of dogmatic theology Bishop Sylvester applied the historical method, which presented church dogmas in their historical development. This approach is fundamentally different from the one used in Metropolitan Macarius Bulgakov’s Orthodox Dogmatic Theology. The article aims to describe the Bishop Sylvester’s manner of teaching theology based on archival research. In the Institute of Manuscripts of the Vernadsky National Library of Ukraine there has been preserved the corpus of unpublished memoirs about Bishop Sylvester by some graduates of the KThA over the years. In those records considerable attention is paid to Bishop Sylvester’s educational work. Bishop Sylvester’s teaching was marked by polemical controversy with the trends in Western theology and philosophy of his time. Just as his books on theology, his lectures followed the historical method. The contemporaries noted the deep enthusiasm, with which Bishop Sylvester lectured, seeking to bring the divine truths closer to his student’s hearts as well as minds.

Книга Валентина Степашкина «Преподобный Серафим Саровский», посвящённая жизни великого святого, вышла в 2018 году в серии ЖЗЛ и вызвала много споров. Игумен Пётр (Мещеринов) сформулировал её основные результаты кратко и броско: «1) колокольни не было, 2) камня не было, 3) кормления медведей не было, 4) разбойников не было, 5) беседы с Мотовиловым не было»1. Неужели правда ничего не было? — Нет! были, были! И медведи, и колокольни, и камни, и беседы, и разбойники. Но были и десятилетия богословских спекуляций без попыток опоры на факты и архивные данные, были неумеренные почитатели, были талантливые фантазёры, была даже политическая конъюнктура и личное соперничество.
Valentin Stepashkin's book, The Venerable Seraphim of Sarov, on the life of the great saint, was published in 2018 in the ZHZL series and caused much controversy. Hegumen Pyotr (Meshcherinov) summed up its main results succinctly and catchily: "1) there was no bell tower, 2) no stone, 3) no bear feeding, 4) no robbers, 5) no conversation with Motovilov "1. Was it really all right? - No! There were, there were! And bears, and bell towers, and rocks, and conversations, and robbers. But there were also decades of theological speculation without any attempt to rely on facts and archival data, there were immoderate admirers, there were talented dreamers, there was even political conjuncture and personal rivalry.
Review on: Jean-Claude Larcher "On the Principles of the Proper Use of Patristic Research in Orthodox Theology"
Authors: Лаут Эндрю 
Published: August 2021

В своей статье Жан-Клод Ларше формулирует актуальный вопрос о месте патристики в современной гуманитарной науке. Нельзя отрицать, что сегодня патристику лишили того положения, которое она занимала на протяжении большей части прошлого века (равно как и во времена более отдалённые). На момент проведения первой Международной патристической конференции в Оксфорде в 1951 году основным намерением её организатора, каноника Фрэнка Кросса, было создание площадки для изучения святоотеческого наследия. Этот процесс, по задумке Кросса, должен был осуществляться на пути сотрудничества между учёными-христианами, принадлежащими к различным церковным традициям. Патристика считалась основанием любого подлинно-традиционного христианского богословия.
In his article Jean-Claude Larcher formulates the pertinent question of the place of patristics in contemporary humanities scholarship. There is no denying that patristics today has been deprived of the position it occupied for most of the last century (as well as in more distant times). At the time of the first International Patristic Conference in Oxford in 1951, the main intention of its organiser, Canon Frank Cross, was to create a forum for the study of the patristic heritage. This process, as Cross envisioned, was to be carried out through collaboration between Christian scholars belonging to different ecclesial traditions. Patristics was seen as the foundation of any truly traditional Christian theology.
Review on: Taylor Ch. Secular Age. M.: BBI, 2017. 967 p
Authors: Давыдов Олег Борисович 
Published: August 2021

Написанная в 2007 году и переведённая на русский язык в 2017 году книга «Секулярный век» являет собой развитие философской и повествовательной стратегии, которая присутствовала в предшествующих работах автора. Как специалист по философии Гегеля, Тейлор исходит из видения истории как онтологически обусловленного процесса, каждое событие которого вписано в универсальный процесс. В этой грандиозной по замыслу и исполнению тысячестраничной работе Тейлор исследует основополагающий для современности процесс — наступление секулярности и трансформацию религии, произошедшую в западном мире или, как определяет ареал своего исследования автор, в североатлантическом регионе мира, включающем Западную Европу и Северную Америку. В центре внимания Тейлора так называемое «социальное воображаемое», интегральное описание того, как люди воспринимают и описывают себя в своей повседневной жизни. Будучи более универсальной, чем рационально артикулированные теоретические средства самоописания, воображаемое выступает фоном для социальных практик, и изменения в воображении неизбежно связаны с изменением этих практик.
Written in 2007 and translated into Russian in 2017, The Secular Age is a development of a philosophical and narrative strategy that was present in the author's earlier works. As a specialist in Hegel's philosophy, Taylor proceeds from a vision of history as an ontologically conditioned process, with each event inscribed in a universal process. In this grandiose work of a thousand pages by design and execution, Taylor explores a process that is fundamental to modernity - the coming of secularism and the transformation of religion that took place in the Western world or, as Taylor defines the area of his research, in the North Atlantic region of the world, including Western Europe and North America. Taylor's focus is on the so-called "social imaginary", an integral description of how people perceive and describe themselves in their everyday lives. More universal than rationally articulated theoretical means of self-description, the imaginary acts as a backdrop for social practices, and changes in the imaginary are inevitably linked to changes in these practices.
Functional relationship of arterial blood pressure, central venous pressure and intracranial pressure in the early phase after subarachnoid hemorrhage
Authors: Maissen Gabriela , Narula Gagan , Strässle Christian , Willms Jan , Muroi Carl , Keller Emanuela 
Published: August 2021

BACKGROUND: Intracranial pressure (ICP) and arterial blood pressure (ABP) are related to each other through cerebral autoregulation. Central venous pressure (CVP) is often measured to estimate cardiac filling pressures as an approximate measure for the volume status of a patient. Prior modelling efforts have formalized the functional relationship between CVP, ICP and ABP. However, these models were used to explain short segments of data during controlled experiments and have not yet been used to explain the slowly evolving ICP increase that occurs typically in patients after aneurysmal subarachnoid hemorrhage (SAH). OBJECTIVE: To analyze the functional relationship between ICP, ABP and CVP recorded from SAH patients in the first five days after aneurysm. METHODS: Two methods were used to elucidate this relationship on the running average of the signals: First, using Spearman correlation coefficients calculated over 30 min segments Second, for each patient, linear state space models of ICP as the output and ABP and CVP as inputs were estimated. RESULTS: The mean and variance of the data and the correlation coefficients between ICP-ABP and ICP-CVP vary over time as the patient progresses through their stay in the ICU. On average, after an SAH event, the models show that a) ABP is the bigger driver of changes in ICP than CVP and that increasing ABP leads to reduction in ICP and (b) increasing CVP leads to an increase in ICP. CONCLUSIONS: Finding a) agrees with the hypothesis that patients with subarachnoid hemorrhage have defective autoregulation, and b) agrees with the positive correlation observed between central venous pressure and intracranial pressure in the literature.

Published: August 2021

Hydrometallurgical leaching process has been identified as a viable procedure for recovering metals of value from their matrices. The optimization of zinc recovery from sphalerite in nitric acid solution was carried out in this study. The Central Composite Rotatable Design (CCRD) of Response Surface Methodology (RSM) and Particle Swarm Optimization (PSO) tool in matlab were deployed for the optimization studies. RSM modeling gave optimum conditions of 73.0 °C leaching temperature, 3.48 M acid concentration, 0.027 g/mL solid/liquid ratio, 411.02 rpm stirring rate, and 82.82 minutes leaching time; with a zinc yield of 87.67 %. With PSO, about 86.9 % zinc was recovered at a leaching temperature of 69.1 °C, acid concentration of 1.8 M, solid/liquid ratio of 0.031 g/mL, stirring rate of 270 rpm and leaching time of 85 minutes. Thus, PSO and RSM proved to be good optimization tools.

AbstractBrain and other central nervous system (CNS) tumors are among the most fatal cancers and account for substantial morbidity and mortality in the United States. Population‐based data from the Central Brain Tumor Registry of the United States (a combined data set of the National Program of Cancer Registries [NPCR] and Surveillance, Epidemiology, and End Results [SEER] registries), NPCR, National Vital Statistics System and SEER program were analyzed to assess the contemporary burden of malignant and nonmalignant brain and other CNS tumors (hereafter brain) by histology, anatomic site, age, sex, and race/ethnicity. Malignant brain tumor incidence rates declined by 0.8% annually from 2008 to 2017 for all ages combined but increased 0.5% to 0.7% per year among children and adolescents. Malignant brain tumor incidence is highest in males and non‐Hispanic White individuals, whereas the rates for nonmalignant tumors are highest in females and non‐Hispanic Black individuals. Five‐year relative survival for all malignant brain tumors combined increased between 1975 to 1977 and 2009 to 2015 from 23% to 36%, with larger gains among younger age groups. Less improvement among older age groups largely reflects a higher burden of glioblastoma, for which there have been few major advances in prevention, early detection, and treatment the past 4 decades. Specifically, 5‐year glioblastoma survival only increased from 4% to 7% during the same time period. In addition, important survival disparities by race/ethnicity remain for childhood tumors, with the largest Black‐White disparities for diffuse astrocytomas (75% vs 86% for patients diagnosed during 2009‐2015) and embryonal tumors (59% vs 67%). Increased resources for the collection and reporting of timely consistent data are critical for advancing research to elucidate the causes of sex, age, and racial/ethnic differences in brain tumor occurrence, especially for rarer subtypes and among understudied populations.

Published: August 2021

Objetivo: analisar os conhecimentos e atitudes da equipe de enfermagem para promoção da termorregulação neonatal. Método: realizaram-se 11 entrevistas semiestruturadas, nos meses de novembro a dezembro de 2020, com membros da equipe de enfermagem da maternidade de um Hospital Universitário, posteriormente submetidas a análise temática e categorizadas em duas unidades temáticas intituladas: conhecimentos da equipe e atitudes da equipe. Resultados: percebeu-se uma lacuna de conhecimento entre profissionais técnicos e enfermeiros sobre o tema. Os participantes souberam elucidar corretamente as repercussões clínicas da termorregulação inadequada, e citaram os recursos materiais disponíveis para promovê-la, tais como berço aquecido e incubadora. Referente aos cuidados de enfermagem, principalmente o banho, percebeu-se que a equipe segue as recomendações da Organização Mundial da Saúde e do Ministério da Saúde, mas estas foram tardiamente implementadas na maternidade. Conclusão: a maioria das atitudes corroboram com as recomendações mais atuais para a promoção e manutenção da termorregulação do neonato.

The objective of this study was to evaluate soil macrofauna as a bioindicator of soil quality in successional agroforestry systems and secondary forests. The study was conducted in the southern lower region of Bahia in Brazil, in two areas: a successional agroforestry system (AFS18) and native forest (NF). AFS18 consists of two species: mahogany (Khaya ivorensis and Khaya grandifoliola), açaí (Euterpe oleracea), cacao (Theobroma cacau) and banana (Musa spp.). Sampling was carried out in the dry (June) and rainy (October) seasons of 2019, and eight soil monoliths were collected in both areas. A total of 889 individuals from the soil macrofauna were sampled. The highest frequency (RF) of taxons occurred in NF in the rainy season, and the groups that stood out were: Oligochaeta with 42% FR in ASF18, Formicide with 33.9% in NF and Isoptera with 58% in AFS18. The macrofauna structure of the soil varied according to the time of collection. The density of macrofauna individuals differed between areas only in the dry season. The highest number of ind.m² was observed in the area NF (378) when compared to ASF18 (196). TOC, Mg2+, Al3+ and CTC were related to AF on both occasions of collection and AFS18 in the rainy season, K+, P and pH were associated with AFS18 in the dry season. The diversity, equitability and richness of the soil macrofauna was greater in AF area. HFA18 in the rainy season was similar to NF, favoring colonization of the area by soil macrofauna organisms.
