Вдосконалення підвіски стрічки Вантажного конвеєра
Authors: Дрозд О. В. 
Published: March 2022

Аналіз досвіду експлуатації стрічкових транспортерів підтверджує головні переваги конвеєрного транспорту - високий рівень продуктивності праці, на основі автоматизації роботи обладнання, можливість транспортування широкої номенклатури вантажу і низькі виробничі витрати. Вони є одним з основних засобів безперервного технологічного транспорту при навантаженні вугілля, руди, гравію в морських портах. Застосування стрічкових конвеєрів не тільки в берегових, але і в складі суднових вантажних комплексів зумовило необхідність створення високопродуктивних стрічкових конвеєрів з великим міжремонтним періодом експлуатації. Значні капітальні витрати на придбання стрічкових конвеєрів компенсуються низькими експлуатаційними витратами. Собівартість одиниці вантажу стрічковими конвеєрами нижче, ніж у інших транспортних засобів, що застосовуються в складі морських перевантажувальних комплексів. Практика використання стрічкових конвеєрів відомих конструкцій різного призначення, виконання і типорозмірів показує, що всі без винятку зазначені конвеєри мають принципову ваду - швидким руйнуванням елементів підвіски стрічки. Динамічні удари при навантаженні і переміщенні вантажу призводять до ще більшого зниження терміну служби стрічки і підвіски, а також суттєвого зростання енергоємності процесу транспортування. Ці процеси призводять до передчасного виходу конвеєра з ладу, втрат вантажу, пиловим забруднення і втрати його якості при транспортуванні. Стрічкові конвеєри настільки удосконалилися, що фактично досягли певного "порогу модернізації", за яким не проглядаються реальні шляхи поліпшення експлуатаційних властивостей в рамках традиційної схеми роликового конвеєра. Підтвердженням цього є той факт, що в останні роки патентними органами в світі видаються поодинокі патенти в області конвеєробудування які не є принциповими для подальшого розвитку цього перспективного і необхідного виду транспорту. Поставлена задача вирішується тим, що система амортизації стрічки транспортера, що складається з основи, демпферів з магнітореологічного еластоміру, блоку живлення та керування, та яка відрізняється тим, що демпферів з еластоміру, закріплені на основі, виконані у вигляді трьох концентричних циліндрів різної висоти, в оболонці з високомолекулярного поліетилену, сигнал на керування властивостями та порядком залучення до дії яких надходить від датчиків навантаження та удару, що розташовані під основою у місці навантаження вантажу.

Melatonin application on phytochemical compositions of Agastache foeniculum under water-deficit stress
Authors: Mohammadi Hamid , Moradi Shahla , Hazrati Saeid , Aghaee Ahmad 
Published: March 2022

Background: Agastache foeniculum is one of the perennial aromatic plants of the Lamiaceae family. The essential oil (EO) of this plant has potent antibacterial and antifungal properties, and hence it is extensively used in the pharmaceutical and food industries. Water-deficit stress occurring at any plant growth stage changes the morphological, phytochemical, and physiological processes. Melatonin is considered as a new kind of plant growth regulator which increases plant tolerance to environmental stresses.
Hypotheses: The response to water deficit in A. foeniculum is Mel-dependent and affects their physiological and phytochemical characteristics
Studied species: Agastache foeniculum
Study site and dates: Tabriz, Iran, 2019.
Methods: For this purpose, plants were subjected to water-deficit stress, which was followed by foliar application of melatonin as biostimulants on dry matter and secondary metabolites of A. foeniculum .
Results: Results indicated that water-deficit stress (at 60 % of Field capacity) increased shoot dry weight, total phenol, anthocyanins and flavonoids content as well as EO content. Application of various melatonin concentrations improved the content of the mentioned traits. According to GC-MS analysis, ten chemical compounds were recognized in the EO composition of A. foeniculum . The most important EO compound (%) in the studied treatments was methyl chavicol, under severe water-deficit stress conditions with Mel at concentration of 100 μM.
Conclusions: The results indicated that the application of Mel (at 100 µM) as a bio-inducer can alleviate the detrimental effects of water-deficit stress (at 60 and 30 % field capacity) and improve the quality of EO.

Abstract
Objectives
The dominant discourse in literature often constructs heterosexual African, Caribbean, and Black (ACB) masculinity as inherently problematic and in need of “correction, repair, or rescue.” This discourse privileges hegemonic male standards and conceals the power relations that shape racialized masculinities. Our study of self-identified heterosexual ACB men and male youth examines how performative and perceptual attenuations of hegemonic masculinity can moderate social and behavioural vulnerabilities in the context of HIV prevention, transmission, and survival.

Methods
We used descriptive qualitative methods informed by community-based participatory research. Individual in-depth interviews and focus group discussions were conducted with 63 ACB men and male youth (aged 16 and above) residing in Ottawa, Canada, including community leaders, HIV service providers, and decision makers. The interviews were transcribed verbatim, and thematically analyzed with NVivo software. Member-checking, peer debriefing, and external audit ensured trustworthiness of data.

Results
ACB men and male youth define masculinity by their ability to provide for, protect, love, and lead their families. Within ACB cultures, men demonstrate their masculinity through their traditional role as family breadwinners, and are expected to be strong, bold, and responsible. This positive view of masculinity is potentially beneficial to the well-being of ACB men and male youth, and challenges mainstream notions of Black masculinity as uncontrolled, risky, toxic, or even predatory.

Conclusion
A positive view of masculinity among ACB heterosexual men and youth could support future practice and policy interventions aimed at strengthening community responses to HIV and health.
Sensory and Functional Properties of Linum usitatissimum (Flaxseed) Incorporated Pulse based Ready to Cook (RTC) Health Mix for Women of Reproductive Age
Authors: Katte Megha M. , Vijayalakshmi D. 
Published: March 2022

Background: Scientific evidence supports therapeutic properties of flaxseed; however, a large sector of the population is still unaware of the associated benefits and its possible applications as usage in food prodcuts. Flaxseed is popularly known for its high alpha-linolenic acid content, but is also a source of lignan, fibre and protein that are biologically active in the prevention of some non-transmissible chronic diseases. Methods: Methodology involved in the study has focused on formulation of health mix by standardising the amount of flaxseed incorporated, sensory evaluation of the formulated product by semi-trained panel members, assessment of functional properties and analysis of macronutrient composition. Result: The developed health mix is a good source of protein (15 g per 100 g) and fiber (13 g per 100 g). Water soluble index of 5.23 per cent, swelling power 12.50 per cent and solubility index of 17.62 per cent was observed in the developed flour. Health mix containing 10 g of flaxseed per serving had best acceptance.
Intercultural communicative competence in foreign language learning
Authors: Araujo Portugal Juan Carlos 
Published: March 2022

The importance of teaching both language and culture inseparably are widely acknowledged by both instructors and students. As a result, new concepts such as intercultural communicative competence have emerged. This means that this new skill has to be promoted and fostered so that students can develop it and interact with other people effectively in a more culturally diverse setting. This paper aims to analyse the role of this new competence in foreign language learning, which is characteristic of 21st-century citizens. The study, therefore, conducts a literature review. In this process, teachers, and to a lesser extent coursebook, play a paramount role. Even though all the agents involved in the teaching-learning process value its importance, there are some factors such as a lack of appropriate training on the part of teachers, inadequate content and materials contained mainly in coursebooks, and effective ways of assessment, which prevent the development of this new 21st-century skill.

Published: March 2022

In the past few decades, total ankle replacement (TAR) has become the backbone of treatment for end-stage ankle osteoarthritis, with improving outcomes. The aim of the present study was to present the long-term survival of the HINTEGRA TAR. This single-center retrospective cohort study included 722 ankles in 683 patients who underwent HINTEGRA TAR for end-stage ankle osteoarthritis. We performed a survival analysis and assessed potential risk factors. Clinical outcomes and patient satisfaction were determined. The cumulative survival rate was 93% (95% confidence interval [CI], 91% to 95%) at 5 years, 86% (95% CI, 83% to 88%) at 10 years, and 82% (95% CI, 78% to 85%) at 15 years. Aseptic loosening was the most common reason for revision, accounting for 54 (43%) of 126 revision procedures. A secondary etiology was associated with a lower risk of revision than primary or posttraumatic. The HINTEGRA TAR results in desirable long-term implant survival with an acceptable revision rate. Coronal-plane instability must be evaluated and addressed at the time of the index surgery.

» In 2016, a total of 48,771 hospital-acquired conditions (HACs) were reported in U.S. hospitals. These incidents resulted in an excess cost of >$2 billion, which translates to roughly $40,000 per patient with an HAC.» Current guidelines for the prevention of venous thromboembolism and surgical site infection consist primarily of antithrombotic prophylaxis and antiseptic technique, respectively.» The prevention of catheter-associated urinary tract infection (CA-UTI) and in-hospital falls and trauma is done best via education. In the case of CA-UTI, this consists of training staff about the indications for catheters and their timely removal when they are no longer necessary, and in the case of in-hospital falls and trauma, advising the patient and family about the patient’s fall risk and communicating the fall risk to the health-care team.» Blood incompatibility is best prevented by implementation of a pretransfusion testing protocol. Pressure ulcers can be prevented via patient positioning, especially during surgery, and via postoperative skin checks.

¿Cuánta desigualdad en exposición a alta polución por PM10 es demasiada para considerarla ambientalmente injusta? Una evaluación para grupos vulnerables en dos grandes ciudades españolas
Las desigualdades en la afección o carga ambiental (externalidades negativas, peligros, malestar, etc.) entre lugares y personas son un tema de creciente interés. Se han publicado abundantes estudios, utilizando métodos diversos, en los que se concluye que, a menudo, existe discriminación e inequidad. Ahora bien, desde el punto el punto de vista de la formación de decisiones públicas y de la gobernanza una pregunta sigue siendo necesario responder con claridad: cuánta desigualdad existe y si ésta es demasiada para ser calificada de injusta y justificar, por tanto, la acción pública. En este artículo se aborda esa cuestión a partir de un estudio de caso relativo al peligro por polución del aire en Madrid y Barcelona (España). A tal fin se examina la distribución espacial de varios grupos de población vulnerables y su exposición potencial a alta concentración de PM10 en la atmósfera, usando un método razonable que implica el uso de SIG y técnicas estadísticas. La adopción de un criterio operativo y explícito de imparcialidad posibilita medir la cantidad de desigualdad para cada grupo de población y determinar si ésta excede significativamente al criterio de referencia. Ello facilita una valoración más certera de la situación por los ciudadanos y los decisores públicos.

Published: March 2022

Abstract
Long-term downhole restrictions could potentially create unfavorable impacts for operators: impeding or preventing production and any further interventions. A well in offshore East Malaysia had encountered a stuck Wireline Retrievable Safety Valve (WRSV) issue, with its lock-mandrel partially parted after several unsuccessful fishing attempts. The attempts were finally aborted, leaving the stuck WRSV downhole without a fishing neck for almost 25 years.
In July 2019, initial engagement was made to re-establish access to this well for perforation and production. The solution was to use an Electric Line (EL) milling tool with a tractor and customized milling bit. The aim was to unlock the lock mandrel, which was holding the safety valve in place, and minimize any trace impact of milling on downhole accessories as ability to re-utilize the nipple profile for future safety valve deployments was also targeted, hence maintaining the assembly in a functional state was crucial.
This EL milling method has proven to be an efficient means of performing the operation with minimal: cost, manpower requirement, and operational timeline.
This paper describes the process of designing the operation, and the subsequent execution phase.
Optimizing Drillouts Using Live TFA

Published: March 2022

Abstract
This paper examines how real-time force monitoring keeps operations on path by decreasing operational failures (such as stuck or parted pipe), reducing non-productive time (NPT), and increasing drillout efficiency (hour/plug).
Utilizing interactive tubing force analysis (TFA) models with real-time data overlays provides coiled tubing operators with the data needed to reduce stuck pipe events, increase drillout efficiencies, and decrease mechanical failures (both on the surface and downhole). The key to optimizing efficiencies is maintaining consistent data that can be analyzed with the TFA. One current challenge is that analyzed data can only affect future operations if engineering controls are executed in the field. By using the interactive TFA and real-time operational data synchronously, users can positively impact their current and future operations by using data-driven decisions instead of predetermined processes.
By implementing a cloud-based application in conjunction with software that acquires and stores field data, one field-based end user recognized real-time divergence from the modeled parameters. This is a key indicator of potential failures. The application allows for on-the-fly procedural corrections (such as stop and circulate) to alleviate operational risk for stuck pipe instances. In one case, the application indicated forewarned risk while running in hole that would have saved the service company and Exploration and Production (E&P) company more than 48 hours in NPT.
Having cloud-connected software with pre-defined warnings provides the field, management, and engineering staff with real-time access to the same data, allowing quick and inclusive decisions to be made prior to potential failures. Without this implementation, only post-job analysis would have revealed the divergence of the field data from the predictive data. The live feed of operational data provided by the application prevented stuck pipe scenarios when well conditions changed. Personnel could not have made this prediction if the coiled tubing (CT) operator was relying solely on the pre-defined job scope and pre-job planning procedures.
This paper expands on previous documentation where the TFA and real-time data were manually overlaid to significantly reduce an E&P's risk. This novel refinement of technology coalesces essential information to create a holistic view of operations thereby preventing issues rather than analyzing them after the fact.
Digital Pressure Testing Software Improves Safety and Efficiency When Applied to Well Intervention Campaign
Authors: Cole Rachel , Hernandez Alexis , Spencer Bryan , Cully Rick , Franklin Alyssa 
Published: March 2022

Abstract
Well intervention requires reliable pressure data and real-time monitoring of multiple annuli simultaneously to confirm appropriate pressure response of actuated valves and components. The current industry standard uses traditional monitoring methods which involve reading digital crystal gauges and manually recording the values at increments for interpretation. This paper presents a case study where the operator reduced the probability of human error, and improved assurance and safety by utilizing a digital solution during an intervention campaign.
During operations, personnel used digital pressure testing software to monitor annulus pressures while performing acid stimulation pressure pumping operations and verified test outcomes during additional intervention operations. To conduct these tests, pressure transducers were tied into the locations where a digital gauge would normally be located, and cables connected to a data acquisition unit for interpretation by operations personnel. The software monitored and analyzed the data in real time to validate the operator's criteria, and all real-time data was able to be viewed both on-site and remotely. When tests completed, reports were auto generated and stored for ease of access.
The process described above resulted in a safer testing environment by utilizing transducer cables and a data acquisition unit, allowing personnel to remain a safe distance away, as opposed to the traditional method of taking manual readings near pressurized areas. High resolution digital data was constantly monitored, instead of taking readings in increments, allowing for the improved visualization of annulus or tubing pressures in real time and improving the efficiency of operations. This on-site and remote real-time visualization allowed for better communication and interpretation of appropriate pressure response when shifting sleeves, equalizing pressures, or performing coiled tubing cleanouts. When all intervention work was completed, a comprehensive end of well report was generated to provide a record of all operations and reduce communication errors during handover or subsequent operations throughout the well lifecycle.
This digital software solution and equipment tie in used for intervention operations provides a safer environment, more accountability, improved decision making, and more efficient communication in handover. The ability for real time monitoring of pressure response improves participation and collaboration between personnel both on-site and in remote locations. Comprehensive documentation provides an auditable history of events which can be used to improve future operations and promote best practices.
