При эксплуатации фрикционного узла в процессе замедления вращения привода на фрикционных парах выделяется большое количество энергии, которая рассеивается в окружающую среду. Через вентиляционный канал благодаря разнице давлений между внутренними и внешними отверстиями проходят потоки охлаждающего воздуха. Габаритные параметры тормозного диска являются определяющими критериями при проектировании, тогда как эксплуатационные показатели вентиляционного аппарата тормозного диска отходят на второй план.Исследования, посвященные определению параметров работы вентиляционного аппарата и разработки критериев его оценки эффективности, практически отсутствуют. На основании обзора литературы по данному вопросу была теоретически обоснована зависимость критерия системы охлаждения, а именно расхода воздуха от конструктивных параметров вентиляционных каналов и эксплуатационных факторов омываемой среды.Одной из разновидностей математического моделирования является метод численного моделирования. С помощью метода конечных элементов в программном продукте ANSYS представлено моделирование работы вентиляционного аппарата с прямыми вентилируемыми каналами и дана оценка эффективности работы вентиляционного аппарата тормозного диска.При изменении геометрических параметров вентилируемых каналов тормозного диска (углы входа и выхода воздушного потока, количество ребер, радиус скругления ребер) оценивались изменения эксплуатационных показателей работы вентиляционного аппарата. В процессе исследований было установлено, что с увеличением угла выхода воздушного потока скорость воздушного потока возрастает и, соответственно, возрастает расход воздуха, проходящего через вентиляционный аппарат. Помимо этого моделировались траектории движения воздушного потока в вентиляционном аппарате тормозного диска. Недостатком данного исследования является отсутствие учета вихреобразования.На основании теоретических исследований и численного моделирования работы вентиляционного аппарата можно сделать вывод, что вынужденного охлаждения недостаточно для эффективного функционирования фрикционного узла в устойчивом тепловом диапазоне. Для этого необходимо определить критерии оценки работы вентиляционного аппарата тормозного диска, выяснить степень влияния конструктивных и эксплуатационных факторов на критерии оценки. В качестве критериев оценки исследователями приводятся такие факторы, как скорость на входе и выходе из вентилируемого канал и расход воздуха, проходящего через вентиляционный аппарат.
Blockchain and Accounting Governance: Emerging Issues and Considerations for Accounting and Assurance Professionals
Authors: Smith Sean Stein , Castonguay John “Jack” 
Published: June 2020

ABSTRACT
Blockchain technology has been a disruptive force in currency, supply chain, and information sharing practices across a variety of industries. Its usage has only recently expanded into assurance and financial reporting. This paper explores blockchain's impact in these areas and provides guidance for organizations and auditors utilizing blockchain by addressing financial data integrity issues, financial reporting risks, and implications for external auditors and firms' corporate governance practices. Organizations utilizing blockchain must adapt their policies and procedures over internal controls and counterparty risk assessment to address increasing regulation over the distribution of financial data, while their audit committees must be prepared to address these challenges leading up to financial statement preparation. External auditors need to assess blockchain implementation as a financial reporting risk and balance the potentially more reliable and timelier audit evidence obtained from blockchain-based reporting systems against the related increase in internal control testing.
Asuntos de vecinos: langosta, defensa agrícola y la construcción de la sanidad vegetal en México y Centroamérica, siglo XX
Authors: Ortiz Yam Inés , Zuleta María Cecilia 
Published: June 2020

El presente artículo estudia el combate de las plagas de langosta en México y Centroamérica en la primera mitad del siglo XX. De entre otras, la más importante plaga de langosta ha sido la de Schistocerca piceifrons Walker, plaga transfronteriza, compartida entre estos países vecinos desde tiempos prehispánicos. El artículo estudia la lucha contra este acridio en dos momentos: primero, uno nacional, en México, en la década de 1920, que se enfoca principalmente en las campañas contra la langosta en Yucatán y Veracruz; y después, un segundo momento, mexicanocentroamericano, entre 1940-1950, con la formación del Comité Técnico Internacional de lucha contra la langosta en México y América Central. El análisis de la primera etapa local y nacional de las campañas contra la langosta reconstruye cómo y con qué instrumentos normativos y dispositivos científicos e institucionales se buscó combatir y controlar la plaga en el Golfo y la península de Yucatán, explicando el surgimiento de una política pública estatal y federal destinada a la defensa agrícola. El segundo momento, la campaña mexicanocentroamericana contra el acridio entre las décadas de 1940-1950, se estudia como una experiencia que desbordó los principios y métodos de la defensa agrícola nacional, conduciendo a la creación de organismos de control y supervisión de sanidad animal y vegetal a escala transnacional, a acuerdos intergubernamentales y a la creación de dispositivos e instrumentos de cooperación científica, técnica y sanitaria para toda el área mesoamericana, impulsados por la FAO. El artículo argumenta que la langosta transnacional interconectó diversas biorregiones a su paso, impulsando tanto medidas locales de control como también la normalización nacional y supranacional de políticas de protección y sanidad vegetal y de investigación entomológica aplicada, contribuyendo así al nacimiento de una biogeopolítica agropecuaria en México y América Central.
Penyelenggaraan Sistem Elektronik Pelaku Usaha Digital dari Perspektif Hukum Perizinan dan Aspek Pertanggungjawabannya
Authors: Niffari Hanifan 
Published: June 2020

Penyelenggaraan sistem elektronik bagi pelaku usaha digital, pemerintah perlu bertindak untuk pengawasan, pengendalian, dan pengaturan segala aktivitas terkait penyelenggaraan sistem elektronik bagi pelaku usaha digital. Implementasinya, pengawasan dan pengendalian oleh pemerintah dirasa kurang efektif karena penyelenggara sistem elektronik pelaku usaha digital hanya melakukan pendaftaran kepada pemerintah dan sanksi administratif yang diberikan hanya berupa dikeluarkan dari daftar penyelenggara sistem elektronik. Permasalahan muncul karena kurangnya efektifitas pengendalian dan pengawasan bagi penyelenggaraan sistem elektronik pelaku usaha digital. Kerugian yang diakibatkan kesalahan dan kelalaian dalam penyelenggaraan sistem elektronik menimbulkan tanggung jawab hukum bagi penyelenggara sistem elektronik khususnya pelaku usaha digital. Penulisan membahas penyelenggaraan sistem elektronik dari perspektif hukum perizinan dan pertanggungjawaban hukum dalam penyelenggaraan sistem elektronik. Tujuan penulisan ini adalah membahas pengawasan dan pengendalian penyelenggaraan sistem elektronik saat ini dari perspektif perizinan dan mengkaji pertanggungjawaban hukum dalam penyelenggaraan sistem elektronik. Fokus Metode penelitian yang digunakan adalah yuridis normatif. Jenis penelitian menggunakan library research. Pendekatan penelitian menggunakan pendekatan normatif. Data yang digunakan data sekunder berupa peraturan perundang-undangan dan teori-teori ahli hukum. Anlisa data menggunakan deskriptif analitis. Penyelenggaraan sistem elektronik perlu dilakukan kajian terhadap perubahan paradigma ke arah instrumen yuridis berupa perizinan melalui keputusan tata usaha negara demi kepastian dan penegakan hukum yang lebih efektif. Hal ini penting karena selain belum diatur, pemerintah harus mencegah dan menetralisir kemungkinan-kemungkinan buruk berupa kerugian dan kejahatan yang ditimbulkan penyalahgunaan kesalahan dalam penyelenggaraan sistem elektronik. Selain perizinan, pertanggungjawaban penyelenggaraan sistem elektronik sangat penting dibahas untuk melihat sejauh mana tanggung jawab hukum penyelenggara sistem elektronik terhadap penyelenggaraan sistem elektroniknya menimbulkan kerugian pengguna dari perspektif perbuatan melawan hukum dan potensi lahirnya strict liability.

Intention. To conduct a comparative analysis of the dynamics of the consolidation of intraarticular fractures of the posterolateral parts of the lateral tibial condyle, the anatomical and functional outcomes of surgical treatment of these patients after plate osteosynthesis with traditional anterolateral and posterolateral transfibular surgical approaches as well.Methodology. A comparative prospective study of the effectiveness of osteosynthesis in patients with fractures of the posterolateral part of lateral tibial condyle in two compatible clinical groups was performed in dynamics for periods of 7–10 days, 1, 3, 6 and 9 months after surgery. In the first group (25 patients), bone osteosynthesis was performed from traditional anterolateral approach (TALA), and in the second group (20 patients), from the posterolateral transfibular approach (PLTFA). The average duration of osteosynthesis operations was compared. The displacements of fragments of the articular surface of the lateral tibial condyle, the indices of the KSS and Lysholm scales, the results of measurements of the angle of flexion and valgus stress test of the knee joint were evaluated. Data processing was performed using the Data Analysis and Chart Master modules (Excel), the Basic Statistics / Tables module (Statistic for Windows) as well.Results and Discussion. In the PLTFA group, the average operation time was (81.0 ± 8.5) minutes (from 67 to 96 minutes), in the TALA group, the duration of operations was 35.8 % longer and averaged (110 ± 5.2) minutes (from 82 to 125 minutes) (p < 0.05). The values of the KSS and Lysholm scales in dynamics showed a steady and statistically significant (p < 0.01) increase with increasing time after surgery without significant differences between the groups. The angle of flexion of the knee joint increased more rapidly during the first three months, then the rate decreased from 6 to 9 months (p < 0.05) without significant differences between the groups. The frequency of displacements of fragments of the articular surface in the first group was statistically significantly (p < 0.05) higher than in the second group. Differences in the valgus-stress test indices in both groups reached a maximum after 9 months – 52 and 30 %, respectively.Conclusion. With PLTFA, surgery duration decreases, articular surface fragments are better reduced, and their subsequent displacement at the stages of treatment is less likely; therefore, this approach is preferable for osteosynthesis of fractures of the posterolateral parts of the lateral tibial condyle.

In this article, I would like to propose an alternative and long view of “1968” which is grounded in black liberation movements, Afrodiasporic cultures, neighborhood-based organizations and sustained and propagated by music and sound. Venturing into this alternative history, I consider the Bronx, Harlem, and Naples, Italy as networks of resistance and nodal junctures for the transmission of Afrodiasporic cultures of opposition. Connecting the mutual influence of global social movements, music and neighborhood-based organizations, my article is also an invitation to start thinking about history through acoustic/musical resonances.
Phosphodiesterase Inhibitors for Alzheimer’s Disease: A Systematic Review of Clinical Trials and Epidemiology with a Mechanistic Rationale
Authors: Sanders Owen , Rajagopal Lekshmy 
Published: June 2020

Background: Preclinical studies, clinical trials, and reviews suggest increasing 3’,5’-cyclic adenosine monophosphate (cAMP) and 3’,5’-cyclic guanosine monophosphate (cGMP) with phosphodiesterase inhibitors is disease-modifying in Alzheimer’s disease (AD). cAMP/protein kinase A (PKA) and cGMP/protein kinase G (PKG) signaling are disrupted in AD. cAMP/PKA and cGMP/PKG activate cAMP response element binding protein (CREB). CREB binds mitochondrial and nuclear DNA, inducing synaptogenesis, memory, and neuronal survival gene (e.g., brain-derived neurotrophic factor) and peroxisome proliferator-activated receptor- γ coactivator-1 α (PGC1 α). cAMP/PKA and cGMP/PKG activate Sirtuin-1, which activates PGC1 α. PGC1 α induces mitochondrial biogenesis and antioxidant genes (e.g.,Nrf2) and represses BACE1. cAMP and cGMP inhibit BACE1-inducing NF κB and tau-phosphorylating GSK3β. Objective and Methods: We review efficacy-testing clinical trials, epidemiology, and meta-analyses to critically investigate whether phosphodiesteraseinhibitors prevent or treat AD. Results: Caffeine and cilostazol may lower AD risk. Denbufylline and sildenafil clinical trials are promising but preliminary and inconclusive. PF-04447943 and BI 409,306 are ineffective. Vinpocetine, cilostazol, and nicergoline trials are mixed. Deprenyl/selegiline trials show only short-term benefits. Broad-spectrum phosphodiesterase inhibitor propentofylline has been shown in five phase III trials to improve cognition, dementia severity, activities of daily living, and global assessment in mild-to-moderate AD patients on multiple scales, including the ADAS-Cogand the CIBIC-Plus in an 18-month phase III clinical trial. However, two books claimed based on a MedScape article an 18-month phase III trial failed, so propentofylline was discontinued. Now, propentofylline is used to treat canine cognitive dysfunction, which, like AD, involves age-associated wild-type Aβ deposition. Conclusion: Phosphodiesterase inhibitors may prevent and treat AD.

The Indonesian country which is famous for its tropical climate has now experienced a shift in two seasons (dry season and rainy season). This has an impact on cropping and harvesting systems among farmers. In large scale this is very influential considering that farmers in Indonesia are stilldependent on rainfall which results in soil moisture. Some types of plants that are very dependent on soil moisture will greatly require rainfall or water for growth and development. Through this research, researchers tried to make a prototype application for watering plants using ATMEGA328 microcontroller based soil moisture sensor. Development of application systems using the prototype method as a simple method which is the first step and can be developed again for large scale. The working principle of this prototype is simply that when soil moisture reaches a certainthreshold (above 56%) then the system will work by activating the watering system, if it is below 56% the system does not work or in other words soil moisture is considered sufficient for certain plant needs.
