Authors: Mustard Cameron A. , Orchard Christa , Dobson Kathleen G. , Carnide Nancy , Smith Peter M. 
Published: October 2023

Abstract
Objective
This study pools two cohorts of workers in Ontario interviewed 18 months following a disabling work-related injury to estimate the association between pain severity, cannabis use, and disability benefit expenditures.

Methods
Among 1650 workers, disability benefit expenditures obtained from administrative records were combined with self-reported measures of pain symptoms and cannabis use. Disability benefit expenditures comprised wage replacement benefits and expenditures on healthcare services.

Results
Past-year cannabis use was reported by 31% of participants, with approximately one third of cannabis use attributed to the treatment of conditions arising from the work-related injury. Condition-related cannabis use was elevated among the 34% of participants reporting severe pain symptoms. In regression models adjusted for age, sex, nature of injury, opioid prescription, and pre-injury chronic conditions, participants reporting condition-related cannabis use had equivalent wage replacement benefit expenditures (β = 0.254, ns) and higher healthcare benefit expenditures (β = 0.433, p = 0.012) compared to participants who did not use cannabis. Participants reporting cannabis use unrelated to conditions arising from their work-related injury had lower wage replacement benefit expenditures (β =  − 0.309, p = 0.002) and equivalent healthcare benefit expenditures (β =  − 0.251, ns) compared to participants not using cannabis.

Conclusion
This novel study of workers’ compensation claimants interviewed at 18 months post-injury did not observe a substantial relationship between cannabis use and disability benefit expenditures, suggesting that neither harm nor significant benefit is associated with cannabis use. These findings contribute to understanding the potential benefits and risks associated with cannabis use in settings that have legalized cannabis use.
Eş konumlu uyduların yakınlaşma izlenmesine gerçek zamanlı mesafe ölçümü tabanlı yaklaşım
Authors: ÖZ İbrahim 
Published: October 2023

Uydu işletmecileri birçok uydudan iletilen başta televizyon yayınları olmak üzere her türlü sinyalin tek bir uydu anteni ile alınabilmesi için çok sayıda haberleşme uydusunu eş konumda (aynı boylamda) işletmektedir. Çok sayıda eş konumlu uydunun ±0,1° kontrol penceresi içinde tutulması daha hassas yörünge belirleme ve oldukça karmaşık yörünge dinamiği problemlerinin çözümünü gerektirmektedir. Uyduların uzaydaki anlık pozisyonlarının ölçülerek aralarındaki fiziksel mesafenin hesaplanması benzetim yöntemlerindeki özellikle zamana bağlıbazı hataları azaltacaktır. Bu çalışmada eş konumda işletilen uydular arasındaki mesafenin hesaplanmasında gerçek zamanlı ölçüm (GZÖ) yöntemi önerilmiştir. Bu yöntemde uyduların anlık yan, yükseliş ve yer istasyonuna mesafe ölçümleri yapılmış ve o anda uzaydaki konumları X, Y, Z olarak hesaplanmıştır. Önerilen yöntem uydu işletmecilerin yaygın olarak kullandığı yörünge dinamiği benzetim (YDS) yazılımı ile karşılaştırılmıştır. Eş konumda işletilen iki uydu, Uydu-A ve Uydu-B için iki yöntem arasındaki ortalama mesafe farkı 0,068 km ve kök ortalama kare hata (KOKH) 0,290 km olarak görülmektedir. Benzer şekilde eş konumda işletilen dört uydu için Uydu-1 ve Uydu-2, Uydu-3, Uydu-4 arasındaki yöntemler arası fark KOKH değerleri sırasıyla 0,257 km, 0,201 km ve 0,219 km’dir. Önerilen GZÖ yöntemi eş konumda işletilen uydular için oldukça başarılı sonuç üretmektedir.
Bu yöntem uyduların uzaydaki konumunu anlık olarak verdiği için birçok hatadan arınmış olup ayrıca itki sistemindeki küçük sızıntılar, küçük meteor çarpmaları gibi etkenlerin neden olabileceği beklenmedik yörünge değişiklikleri de ölçüm içerisindedir. Uydu işletmecileri GZÖ yöntemi ile eş konumlu uydular arası mesafeyi daha gerçekçi ve tahmin edilemeyen yörünge bozulmalarını da içerecek şekilde elde edebilecektir.

Published: October 2023

This study was carried out to assess the in vitro dissolution of Butaproxyvon Capsule (Paracetamol 325mg and Diclofenac 50mg) by calculating the percentage mean drug dissolved and disintegration time, as well as acid neutralizing time. The capsules were tested using three different types of dissolution medium, including pH6.8 phosphate buffer, pH7.5 phosphate buffer, and pH4.5 acetate buffer. The disintegration apparatus was used to calculate the disintegration time, and the acid neutralizing capacity was determined by titrating the capsule content mix with hydrochloric acid with 0.5N sodium hydroxide. Acid neutralizing capacity was found 12.33 mEq/g. Disintegration time was found in the range of 4.40 to 10.00 minutes. % Mean Paracetamol release was found to be almost similar after 60 minutes in all media. % Mean Diclofenac Potassium release was to be found almost similar after 60 minutes by using pH 6.8 and pH 7.5 phosphate media. % Mean drug released for Diclofenac Potassium was found 13% in 4.5 Acetate media, and the released pattern was not uniform. This may be attributed to the low solubility of Diclofenac potassium in 4.5 Acetate media.

Authors: Rodríguez Anzules Marta , Guillén Lozada Enrique , Blasco Santana Luis , Moreno Juara Ángel , Santos Santos Saturnino , Bartolomé Benito Margarita 
Published: October 2023

BACKGROUND: Lymphangiomatous polyp is a very uncommon benign and congenital lesion that appears mainly in the head and neck area. The polyp arises due to a vascular and lymphatic malformation. Medical publications indicate that the number of cases in children is unknown.
CLINICAL CASE: In this paper, two different cases will be presented; one of these dates from 2018 (a 6-year-old boy) and the other one from 2021, the first younger clinical case (a 3-year-old girl) of multiple and bilateral lymphangiomatous polyps of the palatine tonsils. Both these cases were diagnosed during routine procedures at our hospital which will be explained below.
CONCLUSIONS: The clinical suspicion is based on medical history, symptoms (dysphagia, foreign body sensation) and the oral cavity examination, but the definitive diagnosis is histopathological. The treatment consists of a tonsillectomy or a simple surgical excision. Regarding the images (CT-scan or MRI) there is controversy over whether to perform these or not. Although the clinical behavior of tonsillar lymphangiomatous polys is unknown and unclear, our reported cases did not have presence of a malignancy or growth.
ТЕРМОМЕХАНІЧНІ ЯВИЩА У ПОВЕРХНЕВИХ ШАРАХ КОНТАКТУЮЧИХ ДЕТАЛЕЙ ПРИ ТЕРТІ ТА ЗНОШУВАННІ

Published: October 2023

Незважаючи на значну кількість теорій тертя і зношування питання хвилеутворення на поверхнях, що контактують, і в зоні, що випереджає рухому деталь, поки ще не отримали досить глибокого обґрунтування. На основі теоретичних і експериментальних даних, що накопичилися, для оцінки умов тертя і ступеня зношування контактуючих деталей загальноприйнято розглядати групи теорій: 1) геометричні, 2) молекулярні (адгезійні), 3) деформаційні, 4) комбіновані [1]. Найбільшого поширення набула думка, коли тертя обумовлено пластичним відтисненням матеріалу і руйнуванням містків зварювання (Ф. Р. Боуден і Д. Тейбор), яка також підтверджується гіпотезою Ернста і Маргента, де тертя обумовлено адгезією (на молекулярному рівні і шорсткістю поверхні). У той самий час експериментальні результати Ф. Р. Боудена і Д. Тейбора свідчать, що ефект тертя залежить як від сил адгезії, так і від деформації матеріалу в тонкому поверхневому шарі. В результаті застосування значних стискаючих зусиль і дотичних сил тертя, на контакті двох тіл виділяється велика кількість енергії і при слабкому теплообміні з навколишнім середовищем виникають високі градієнти зміни температур, і у разі металевих деталей за певних умов можливий прояв ефекту зварювання як окремих мікронерівностей, так і контактуючих поверхонь загалом, що підтверджується результатами досліджень [2].

Published: October 2023

Objective
Different mechanisms such as psychological, neurobiological, autonomic, and genetic factors might be involved in the etiology of lifelong Premature Ejaculation (PE). Albeit cortical activity changes have been reported, the relationship between PE and impulsivity/decision-making is minimally studied to date. The present study aimed to assess impulsivity and risky decision-making in individuals with lifelong PE for the first time.
Method
26 lifelong PE patients were diagnosed by the International Society for Sexual Medicine (ISSM-2014) criteria and 26 healthy volunteers were recruited. The Premature Ejaculation Diagnostic Tool (PEDT), International Erectile Function Index (IIEF), Barratt Impulsiveness Scale-11 (BIS-11), Patient Health Questionnaire-9 (PHQ-9), Balloon Analogue Risk Task (BART), and Monetary Choice Questionnaire-27 (MCQ-27) were administered.
Results
The mean age was 37.28 (18-55). No differences were found between groups in risky decision-making and impulsivity.
Conclusion
No alterations of impulsivity and risky decision-making were found in lifelong PE patients. Impulsivity may only exist in a subset of individuals with lifelong PE or may only be evident in neural levels or specific subtypes of impulsivity.
Evaluación de la deforestación (2000-2020) en concesiones forestales peruanas en la provincia de Tambopata (Madre de Dios) usando plataformas de datos abiertos
Authors: Valle-Basto Daniel Fernando , Espinosa-Quiñones Tatiana , Limache-de-la-Fuente Daniela 
Published: October 2023

Los datos obtenidos mediante la plataforma Earth Map son comparables a los de la plataforma Geobosques (Perú) para el mismo periodo 2000-2020. Así, a partir del uso de estas plataformas, se pudo estimar que las concesiones forestales de la provincia de Tambopata (Madre de Dios) han perdido 32 115.36 has de cobertura boscosa, representando el 20.96% de toda la deforestación en la región. En el mismo periodo se cambió la legislación forestal del Perú hasta en tres oportunidades. Estos cambios no han permitido implementar estrategias a largo plazo que estén enfocadas en una verdadera gestión forestal sostenible, así como al control y reducción de la deforestación amazónica. También se constató que concesiones de reforestación, de ecoturismo, de uso de productos diferentes a la madera, son usadas primero para tala de árboles con fines maderables, y luego son convertidas en otros usos de la tierra, como campos agrícolas o manejo ganadero o extracción minera. Bajo estas condiciones legales e institucionales de manejo forestal en Madre de Dios, es que las unidades y concesiones forestales no proveen garantías para evitar la deforestación.

A Study of Interplay between Quantitative Ease by US and other Trading Partners and Rupee Volatility
Authors: Kaur Manjinder 
Published: October 2023

In the aftermath of the global financial crisis of 2008-09, leading Central Banks (like the Federal Reserve, Bank of England, European Central Bank and the Bank of Japan) have introduced a multiplicity of untraditional monetary policy measures, so as to stimulate the economies and curb the severity of inflation at the international level. Quantitative Easing may be defined as a policy measure that results in an expansion of the Central Bank’s balance sheet, with an augmentation in the level of the bank’s money in the economy (Bernanke and Reinhart, 2004).
Analysts claim that the strengthening of the dollar, which is being supported by the US Fed Reserve's constant rate hikes to counter rapidly rising inflation, is the principal reason behind the depreciation of the Indian rupee. Moreover, other aspects including the withdrawal of foreign institutional investors also affected the rupee strength and macroeconomic dynamics. According to the IMF, the strength of the dollar causing serious problems such as tightening financial conditions and raising the price of imported goods and services in many emerging economies such as India. Furthermore, an instant hike in oil prices driven by the war between Russia and Ukraine also weakened the rupee and consequently India's current account deficit reaching an absolute record high in the third quarter of the year 2022.
No doubt, in comparison to US dollars, the value of the Indian Rupee has deteriorated in international markets. But at the same time, there are other currencies where the rupee still holds the top spot when evaluated against other currencies throughout the world. Notwithstanding all the challenges, our union finance minister Nirmala Sitharaman reportedly announced that the Indian rupee is considerably better positioned than other international currencies against the greenback. Moreover, these days, India has consistently been working toward making the Indian rupee an international currency and Indian government has progressed significantly towards assigning this status to Indian rupee. In the opinion of certain economists, despite the split, our national currency is still in a stronger position than other currencies when analysed against the US dollar.

<p><strong>Abstract.</strong> Membrane is a separation technology between permeate and feed. The challenge in applying this technology is related to the ingredients that can cause fouling. Cellulose acetate membrane is a porous membrane as a solution to overcome fouling problems.The selectivity level of cellulose acetate membranes in the microfiltration process for water and wastewater treatment is very high. Utilization of kepok banana frond waste as an alternative material for making cellulose acetate membranes that are biodegradable, can be decomposed quickly by microorganisms with a limited shelf life. The aim of this research is to apply cellulose acetate membranes from kepok banana fronds for the microfiltration process in water and wastewater treatment with varying concentrations of acetone using the phase inversion method. The cellulose content contained in the kepok banana fronds is 54.3%. The composition for making the membrane is 2 gr cellulose acetate; PVA 20 ml; and PEG 1.7 ml with various concentrations of acetone 15, 20 and 25 ml. The results of the SEM test of the membrane with a concentration of 25 ml of acetone solvent had the best characteristics with a pore size of 0.0932 μm; thickness of 1.778 mm and swelling index of 9.87%. The highest average flux value was owned by the membrane with a concentration of 20 ml, namely 71.3444 l/m2.hour The lowest flux value was owned by the membrane with a concentration of 25 ml, namely 55.5549 l/m2.hour.</p><p align="left"><strong>Keywords:</strong></p><p>Membrane, Microfiltration, Cellulose Acetate, Banana Frond, Acetone</p>

Published: October 2023

In the article, an information base is formed for the analysis, evaluation and selection of the most effective options for involving unmanned aerial systems in solving the problems of effective land use. According to the authors, the tasks of using land resources in those rural territories that are located remotely and in hard-to-reach areas are particularly relevant. The problems of the annual growth of the population of the planet require the development of high technologies in the agricultural sector, the creation of rational agriculture. A promising direction of precision agriculture is the use of UAVs. Their use is expedient in solving the following tasks: inventorying agricultural land, creating electronic maps of fields, estimating the volume of work and monitoring their implementation, conducting operational monitoring of the state of crops, assessing the germination and yield of certain agricultural crops, protecting agricultural lands appointment, treatment of crops with means of plant protection and pest control. We predict that in the future UAVs will be actively felt in all spheres of human activity, including agriculture. These devices are able to significantly increase labor productivity with a general tendency to reduce production costs.
Recently, innovative tools have appeared and are being used: satellite and computer technologies, which have become available for various spheres of the national economy. Their development and implementation in the agricultural sector led to the development of precision agriculture. The basis of advanced technologies of sustainable farming is the rejection of the use of the plow. A set of techniques is being formed that are aimed at combating soil degradation, which contributes to a decrease in fertility, loss of moisture and a drop in productivity.
