The Lost Treasures of Maitland Bleecker: His Helicopter and Other Innovations
Authors:   US Army (Ret.), Fardink Paul
Published: July 2023

In 1926, a 23-year old Maitland Bleecker submitted a successful proposal to the Curtiss Airplane and Motor Company for an experimental helicopter. As Project Engineer, Bleecker oversaw the design and construction of a full-scale prototype and myriad test flights between 1930 and 1931. Due to the dire Depression economy, a simple gear failure would kill the entire project. Soon afterward, Bleecker's car was broken into, his projector and flight films all stolen - and with them the tangible proof his helicopter had flown. "One day I walked out of the hangar, left the helicopter and ramjet there, and have no idea what became of either of them." The lost treasures of Maitland Bleecker are unquestionably vast; hopefully, this paper will reclaim many of them by showing the impact of his genius on future helicopter innovations, while further providing evidence that he did, indeed, invent the first flyable single-rotor helicopter.
Helicopters and Counterinsurgency: A Delicate Pairing
Authors:   West Chester University, Kodosky Robert
Published: July 2023

U.S. Army officials utilized helicopters in Vietnam according to doctrine developed over the previous decade that had little to do with either Vietnam or counterinsurgency. They failed to reconcile their ideas about the war they anticipated, the one they preferred, with the one in which they engaged. Regarding helicopters, they confused revolutionary technology with revolutionizing tactics and strategy. The evidence suggests, however, that in contrast to the Army, in its consideration to arm helicopters, the Marine Corps proved both flexible and thoughtful. Marines came to advocate arming helicopters for their ability to deliver discriminate, as opposed to, indiscriminate firepower. This incorporated rotary wing aircraft in ways that aligned new technologies, tactics and strategy and affords lessons for today. While helicopters remain essential tools for counterinsurgency, their use continues to generate debate.
Design Studio Insights: Anthropometric Considerations for Ergonomic Design of Wet Services
Authors:   Department of Architecture, Military Institute of Science and Technology (MIST), Dhaka, Bangladesh, Biswas Sudipti
Published: July 2023

Ergonomics is a vital consideration for space design. In architecture education, ergonomics is usually taught in the design studio with various learning methods such as lecture, demonstration, survey, design exercise etc. This article presents an anthropometric study through a design studio exercise dedicated to learning ergonomic considerations. It presents an anthropometric dataset prepared within the studio exercise for designing lavatory and kitchen spaces. In Bangladesh, there is a scarcity of anthropometric data useful for architecture, therefore some reference standards are consulted in the academic and practical field of architecture to integrate ergonomics in design. The presented dataset can serve as a source data for this purpose. Analysis of the derived dataset also raises questions about the suitability of the commonly practiced reference standards.
Tracing Hegel’s Philosophy and Thoughts in Educational Styles of Architecture Design Studios
Authors:   Department of Architecture, School of Architecture and Built Environment, College of Science and Technology, The University of Rwanda, Kigali, Rwanda, Tafahomi Rahman
Published: July 2023

This paper aims to trace the influences of Hegel’s philosophical thoughts and ideas on the architecture design studios’ activities. Hegel is a key figure in the modern history of philosophy that lived in the time of establishing Beaux Art on the skeleton of Academie d’Architecture. Despite the many developments in different areas of education, seemingly, there are still some common grounds between Hegelian philosophy and architecture design studio activities that need to be highlighted and criticized. Content analysis and storytelling based on the structured observation applied in this research to compare two foundations. The results reveal four connections between Hegelian philosophy and architecture design studio activities, including precedents studies and historical dialectic, learning by doing and self-consciousness, crits (critiques) and idealism, and master-apprentice and master-slave theories, respectively. The findings highlight that activities in architecture design studios regenerate through studios, which run based on traditions, disciplines, and styles under the influences of Hegel’s philosophy. In conclusion, while Hegelian thoughts spread through successor philosophers in phenomenology, hermeneutics, existentialism, Marxism, and structuralism, education in architecture design studios has continued without the regeneration of ideas.

Вступ. У статті представлена актуальність впровадження технологій дистанційного навчання в освітній процес на факультеті перепідготовки та підвищення кваліфікації Української військово-медичної академії (далі – ФППК) під час війни та обґрунтовано актуальність найбільш популярних циклів тематичних удосконалень та вебінарів з урахуванням сучасних потреб військово-медичної служби Збройних Сил України. Проведено аналіз підготовки спеціалістів, які пройшли перепідготовку (навчання) на факультеті. Обґрунтовано необхідність та перспективи застосування дистанційного навчання (технологій дистанційного навчання) в системі післядипломної освіти, а саме у ході здійснення безперервного професійного розвитку військових лікарів в умовах воєнного стану.

Метою роботи було проведення аналізу діяльності та визначення перспективних напрямків роботи ФППК в частині підготовки військово-медичних фахівців у ході широкомасштабної агресії російської федерації проти України.

Матеріали і методи. Застосовано методи історичного та теоретичного аналізу наукової літератури та нормативно-правових документів, синтезу, порівняння, узагальнення та прогнозування.

Результати. Впродовж 2022 – 2023 рр. на ФППК в навчальний процес було введено нові цикли тематичного удосконалення, тренінги та вебінари, що відповідали потребам військових медиків у ході бойових дій.  Потужними поштовхами для запровадження форм дистанційного та змішаного навчання на ФППК, стали як поширення респіраторної хвороби COVID-19, так і запровадження воєнного стану в державі. Необхідно зазначити, що за дистанційною формою на факультеті у 2020 році провчилось 511 осіб (16% з усього контингенту, який навчався на ФППК у вказаному навчальному році), з них 485 – лікарі, та 26 – молодших спеціалісти з медичною освітою; у 2021 році – 1354 осіб (67% з усього контингенту, який навчався на ФППК у вказаному навчальному році), з них 1172– лікарів та 182 – молодших спеціалісти з медичною освітою; у 2022 році – 1626 осіб (що становить 64% з усього контингенту, який навчався на ФППК у вказаному навчальному році), з них 1324 лікарів та 302– молодших спеціалістів з медичною освітою. Таким чином, відмічається стале збільшення кількості осіб, які провчились на ФППК за дистанційною формою.

Висновки. Спостерігається стале збільшення кількості осіб, які пройшли навчання на ФППК за дистанційною формою, а саме у 2022 році таких осіб було 1626 (що становить 64% з усього контингенту, який навчався на ФППК у вказаному році навчальному році), у 2021 році – 1354 особи (67%), у 2020 році – 511 осіб (16%) відповідно.

Мета дослідження – визначити обізнаність військових лікарів  щодо діагностики та лікування тривожних, депресивних синдромів і посттравматичного стресового розладу (ПТСР) та їх потреби щодо підвищення поінформованості з цих питань.

Матеріали та методи. Методом випадкової вибірки проведено анкетне опитування 23 військових лікарів, які працюють в Національному військово-медичному клінічному центрі «Головний військовий клінічний госпіталь» та Військово-медичному клінічному центрі  центрального регіону. Питання анкети стосувались використання лікарями діагностичних шкал, призначення фармакологічних препаратів та доцільності розробки сучасних методичних рекомендацій для лікарів загальної практики з цієї проблеми. За результатами дослідження сформована комп’ютерна база даних. Статистична обробка проводилась з використанням програми Microsoft Excel 2007 та стандартного статистичного пакета STATISTICA 6,0.

Результати. Результати анкетного опитування засвідчили, що більшість опитаних військових лікарів (74,9 - 69,6%) використовують в практичній діяльності затверджені МОЗ України медико-технологічні документи, щодо діагностики тривожних і депресивних синдромів, ПТСР. Визначено, що для корекції психоемоційних розладів військові лікарі переважно призначають сучасні анксіолітики (фабомотизол, фенібут) – 43,5%; гідазепам – 34,8%, і тільки 8,7% сучасні антидепресанти (інгібітори зворотного захоплення серотоніну). На питання «При яких коморбідних станах Ви призначаєте гідазепам?» – 39,1% лікарів відповіли «при тривозі»; 30,4% – «при порушені сну»; 17,4% – «при нервозності», 4,3% – при депресії, що обґрунтовує необхідність підвищення поінформованості військових лікарів щодо зваженого підходу до призначення гідазепаму. За результатами опитування 91,3% лікарів мають бажання підвищити рівень обізнаності щодо  призначення сучасних антидепресантів лікарем загальної практики, 95,7% лікарів підтримали доцільність розробки сучасних методичних рекомендацій з цієї проблеми.

Висновки. Визначено проблемні аспекти щодо участі військових лікарів в наданні медичної допомоги військовослужбовцям з коморбідними тривожними, депресивними синдромами, ПТСР та обґрунтовано доцільність розробки методичних рекомендацій «Коморбідні тривожні, депресивні синдроми, посттравматичний стресовий розлад в роботі військового лікаря загальної практики на сучасному етапі».

Digital technology has produced numerous benefits and simplified workers. Nonetheless, this exponential growth in digital technology has increased competition, significantly impacting the finance industry. This significant development in banking presented a vast opportunity that had to be carefully analysed and managed, resulting in intense competition among digital banking products such as mobile banking services, which have helped macro, micro, and small enterprises in Indonesia gain access to more convenient financial services. A regional bank owned one of Indonesia’s provinces, launched a successful mobile banking app with revolutionary features that made transaction easier. The bank updated their mobile app in 2022 as part of their ongoing implementation change from a focus on products to one on customers. In response to user feedback, the new version enhances consumer experience in terms of UI UX and other factors. However, once a market-leading application ranked among the top 10 digital banking products in Indonesia, the mobile banking is presently experiencing a decline in the number of app activations and is being replaced by competitors. Additionally, the bank has difficulty measuring the mobile banking’s digital marketing campaigns. Beginning with an internal and external analysis, a customer acquisition strategy was proposed fo

Does Thromboelastography in Non-Trauma Critical Care Patients Promote The Judicious Use of Blood Products? A Retrospective Exploratory Single Center Observational Study
Authors:   Department of Internal Medicine, West Virginia University, Morgantown, WV, Yu Stephen L , Balakrishnan Bathmapriya ,   Section of Pulmonary, Critical Care, and Sleep Medicine, Department of Medicine, West Virginia University, Morgantown, WV
Published: July 2023

Background: Thromboelastography (TEG) revolutionized the resuscitation of critically ill trauma and cirrhotic patients by improving blood product utilization and survival outcomes. There is limited data on the application and outcomes of non-trauma critical care (NTCC) patients with TEG use. This study compares the blood product utilization, mortality, and other outcomes of NTCC patients using TEG or CCT-guided transfusion. Methods: This is a single-center retrospective observational exploratory study of adult NTCC patients admitted to the medical intensive care unit in a rural academic center. Eligible patients received transfusion of blood products (BPs) guided by CCT or TEG studies. The primary outcome compared BPs transfused. Secondary outcomes included methods to achieve hemostasis, 28-day readmission rate after discharge, and 28-day survival. Results: TEG was used in 80 (70.8%) patients. The TEG group received 4.5 more units of BPs than the CCT group (p=0.003). A clinically significant difference in BPs transfused was seen in packed red blood cells (p=0.064), platelets (p=0.003), and fresh frozen plasma (p=0.020). The methods to achieve hemostasis between the groups were statistically significant (p=0.021). The 28-day readmission-free rate was similar (42.5% vs. 54.5%, TEG vs. CCT, p=0.301), as was the 28-day survival after discharge (p=0.078) in both groups. Conclusions: TEG-guided transfusion increased the number of BPs transfused compared to CCT in NTCC patients. No difference between the two groups in achieving hemostasis, 28-day readmission rate, or 28-day mortality was observed. This study highlights the need to further analyze TEGguided resuscitation prior to adopting TEG into routine practice in NTCC settings.

Sıtma parazitle enfekte olmuş anofel cinsi sivrisineğin ısırması ile bulaşan zoonotik bir enfeksiyondur. Etken, Plasmodium ailesine ait protozoonlardır. Hastalarda akut faz reaktanlarından C-reaktif protein (CRP) ve prokalsitonin (PCT) yükseliğinin görüldüğü de bildirilmiştir .Biz de prokalsitonin yüksekliği ile seyreden 2 sıtma olgumuzu paylaştık. P.falcifarum sıtması olarak tedavi edilen iki olguda da anemi, trombositopeni, CRP ve PCT yüksekliği gözlendi. Prokalsitonin , tiroid bezindeki parafoliküler C hücrelerinden sentezlenen bir akut faz reaktanıdır. Bakteriyel enfeksiyon ve sepsis bulguları olan hastalarda PCT seviyeleri yükselir. Bakteriyel enfeksiyonlar dışında akut sıtma ya da fungal infeksiyonlarda da serum prokalsitonin seviyelerinin arttığı rapor edilmiştir . Mahittikorn ve ark.’nın yaptığı metaanalizde komplike olmayan sıtması olan hastalarda ortalama PCT düzeylerinin; 3,92 ng/mL olduğu , şiddetli sıtması olanlarda ise ortalama PCT düzeylerinin 14.13 ng/mL olduğunu göstermiştir. Bu sonuçlar sıtma hastalarında PCT düzeylerinin yükseldiğini doğrulamaktadır. Tek başına PCT düzeyi, şiddetli/komplike olmayan ve enfekte/enfekte olmamış vakaları ayırt etmek için uygun bir biyobelirteç gibi görülmemiştir .Sıtmanın belirtileri birçok ateşli hastalık ile benzerlikler göstermektedir. Prokalsitonin yüksekliği bakteriyel etkenler dışında sıtma olgularında da yüksek olabilir. Bu nedenle ateş ve PCT yüksekliği ile başvuran hastaların ayırıcı tanısında sıtmanın düşünülmesi gerekir.

Influence of Agnihotra on the Antibiotic Properties of Piper Nigrum L.
Authors: Ahilyadevi A. Kolekar
Published: July 2023

Piper nigrum L., a plant renowned for its medicinal properties and widely employed in Ayurveda as an efficacious antibiotic, holds immense significance. Remarkably, through experimental analysis, the extract derived from Piper nigrum L. has exhibited remarkable efficacy against both gram-negative and gram-positive bacteria. Intriguingly, the Agnihotra therapy, an exceptional approach for treating diverse ailments, harnesses the potent fumes emanating from meticulously chosen plant twigs, combined with clarified butter and a mere pinch of rice, to effectively curb the proliferation of disease-causing bacteria. In the current investigation, we delve into the synergistic impact of the plant extract and Agnihotra technique on the growth patterns of certain pathogenic bacteria. The findings unequivocally establish that Agnihotra therapy unequivocally aids in the control and inhibition of pathogenic bacterial growth. Consequently, we wholeheartedly recommend the employment of Agnihotra treatment in conjunction with the extract derived from Piper nigrum L. to combat and mitigate the adverse effects of pathogenic bacteria

La élite como grupo social ha sido escasamente estudiada a nivel global. En este contexto, este estudio avanza en el análisis de la protección y garantía de los derechos de infancia en colegios de élite. Se desarrolló una investigación cualitativa de diseño de caso múltiple. Como principales hallazgos están la tensión del derecho a la educación de calidad, presentándose un curriculum gerencialista y persuasivo; el derecho a una sana convivencia y a la expresión de la propia identidad, encontrándose dinámicas de silencio en torno a situaciones de violencia, potenciadas por una vivencia de masculinidad hegemónica; y, la tensión en torno al derecho a participar, ser escuchado y opinar, dado que se desarrolla una participación tutelada por parte de los adultos. Se discute respecto de la desprotección de los derechos de infancia en este tipo de establecimientos y la imposibilidad de asegurarlos desde las actuales regulaciones legales. De este modo, los hallazgos del estudio ponen en evidencia que el rezago en el cumplimiento de los derechos de niños, niñas y adolescentes es un tema transversal para los grupos sociales de nuestro país.

Heavy metals pose a serious threat to our environment due to the fact that majority of annual vegetable crops consumed by man and animal are produced from the polluted sites without knowing the level of it taken up by plant which revolves into food chain. This study evaluated the variability of soil physicochemical properties and heavy metals concentration in Owerri municipal dumpsites in Imo State. Samples were collected in three replicates 0, 5 and 10m away from refuge dumpsites at 0 - 30cm depth using soil auger in Ihiagwa, Avu, Abazu and Obinze. Samples were analyzed for soil properties and heavy metals-concentrations using standard methods. The concentrations of the studied heavy metals (Pb and Cr) were compared with the permissible limits of other countries. pH results from the analyzed sampled soils from the four locations were high (6.89, 6.80, 6.59 and 6.40) in Ihiagwa, Abazu, Obinze and Avu respectively while organic carbon followed the trend Ihiagwa>Avu>Abazu>Obinze. Organic carbon and total Nitrogen concentrations followed the same trend in Ihiagwa, Avu, Abazu and Obinze. Pb concentrations in the studied sites were above the standard limit recommended (0.05mg/kg) by Federal Environmental Protection Agency but within limit (100mg/kg) stipulated by European Commission. Nevertheless, Pb concentration was within the tolerance limit set by European Union but should be cautiously minimized to prevent health hazard on man and the environment. The use of refuge dumpsite for cultivation of arable crops should be avoided and lands on cultivation should be given a distance from the refuse sites.
Liver health and the interplay between obesity, alcohol and bariatric surgery
Authors: Geerts A , Onghena L , Lefere S
Published: July 2023

The prevalence of obesity and metabolic consequences, including non-alcoholic fatty liver disease (NAFLD) has become a global health problem. Obesity has an important impact on chronic liver disease even beyond NAFLD, as it accelerates the progression of alcohol liver disease. Conversely, even moderate alcohol use can affect NAFLD disease severity. Weight loss is the gold standard treatment but adherence to lifestyle changes is very low in the clinical setting. Bariatric surgery can improve metabolic components and cause long-term weight loss. Therefore, bariatric surgery could serve as an attractive treatment option for NAFLD patients. A pitfall is the use of alcohol after bariatric surgery. This short review integrates data about the influence of obesity and alcohol on liver function and the role of bariatric surgery.
Hydrological change in southern Australia over 1750 years: a bivalve oxygen isotope record from the Coorong Lagoon
Authors: Chamberlayne Briony Kate , Tyler Jonathan James , Haynes Deborah , Shao Yuexiao , Tibby John , Gillanders Bronwyn May
Published: July 2023

Abstract. Multi-centennial records of past hydroclimate change are essential
for understanding the resilience of ecosystems to climatic events in
addition to guiding conservation and restoration efforts. Such data are also
crucial for examining the long-term controls over regional hydroclimate and
the inherent variability in extreme droughts and floods. Here, we present a
1750-year record of hydroclimate variability in the Coorong South Lagoon,
South Australia, part of an internationally significant wetland system at
the mouth of Australia's largest river, the Murray River. Oxygen isotope
ratios were measured from Arthritica helmsi bivalve shells preserved in sediments. The
oxygen isotope record shows periods of persistent low and high moisture
balance, from ∼500 to 1050 years and from ∼1300 to 1800 years,
respectively, which is consistent with other hydroclimate reconstructions
from the region. The range of oxygen isotope values in the sedimentary
shells does not differ significantly from the estimated range of modern
specimens from the present-day lagoon. These data suggest that the
restricted and highly evaporated modern-day conditions are not markedly
different to the pre-impacted state over the last 1750 years, although the
absence of A. helmsi in the contemporary lagoon is likely a response to increased
salinity, nutrient loading, and anoxia during the last century. These
insights are potentially useful both in guiding management efforts to
conserve and restore the Coorong Lagoon and for understanding long-term water resource availability in the region.

Abstract. As part of the larger mineral systems approach to
Cu-bearing mineralization in northern Norrbotten, this study utilizes
structural geology to set the classic Pahtohavare Cu ± Au deposits
into an up-to-date tectonic framework. The Pahtohavare Cu ± Au
deposits, situated only 5 km southwest of the Kiirunavaara world-class iron
oxide–apatite (IOA) deposit, have a dubious timing, and their link to IOA
formation is not constrained. The study area contains both epigenic Cu ± Au (Pahtohavare) and iron oxide–copper–gold (IOCG; Rakkurijärvi)
mineral occurrences which are hosted in bedrock that has been folded and
bound by two shear zones trending northeast to southwest and northwest to southeast to the east and southwest,
respectively. Structural mapping and petrographic investigation of the area
reveal a noncylindrical, SE-plunging anticline. The cleavage measurements
mirror the fold geometry, which characterizes the fold as F2 associated
with the late phase of the Svecokarelian orogeny. Porphyroclasts with pressure
shadows, mylonitic fabrics, and foliation trails in porphyroblasts indicate
S0/S1 is a tectonic fabric. The epigenetic Pahtohavare Cu ± Au mineralization sits in brittle–ductile structures that cross-cut an
earlier foliation and the F2 fold, indicating that the timing of the
deposits occurred syn- to post-F2 folding, at least ca. 80 Myr after
the Kiirunavaara IOA formation. A 3D model and cross-sections of the
Pahtohavare–Rakkurijärvi area and a new structural framework of the
district are presented and used to suggest that the shear zones bounding the
area are likely reactivated early structures that have played a critical
role in ore formation in the Kiruna mining district.

Abstract. Thermodynamic and dynamic sea ice thickness processes are affected by differing mechanisms in a changing climate. Independent observational datasets of each are essential for model validation and accurate projections of future sea ice conditions. Here, we present a monthly, Arctic-basin-wide, and 25 km resolution Eulerian estimation of thermodynamic and dynamic effects on wintertime sea ice thickness from 2010–2021. Estimates of thermodynamic growth rate are determined by coupling passive microwave-retrieved snow–ice interface temperatures to a simple sea ice thermodynamic model, total growth is calculated from a weekly Alfred Wegener Institute (AWI) European Space Agency (ESA) CryoSat-2 and Soil Moisture and Ocean Salinity (SMOS) combination product (CS2SMOS), and dynamic effects are calculated as their difference. The dynamic effects are further separated into advection and residual effects using a sea ice motion dataset. Our results show new detail in these fields and, when summed to a basin-wide or regional scale, are in line with previous studies. Across the Arctic, dynamic effects are negative and about one-fourth the magnitude of thermodynamic growth. Thermodynamic growth varies from less than 0.1 m per month in the central Arctic to greater than 0.3 m per month in the seasonal ice zones. High positive dynamic effects of greater than 0.1 m per month, twice that of thermodynamic growth or more in some areas, are found north of the Canadian Arctic Archipelago, where the Transpolar Drift and Beaufort Gyre deposit ice. Strong negative dynamic effects of less than −0.2 m per month are found where the Transpolar Drift originates, nearly equal to and opposite the thermodynamic effects in these regions. Monthly results compare well with a recent study of the dynamic and thermodynamic effects on sea ice thickness along the Multidisciplinary drifting Observatory for the Study of Arctic Climate (MOSAiC) drift track during the winter of 2019–2020. Couplets of deformation and advection effects with opposite signs are common across the Arctic, with positive advection effects and negative deformation effects found in the Beaufort Sea and negative advection effects and positive deformation effects found in most other regions. The seasonal cycle shows residual deformation effects and overall dynamic effects increasing as the winter season progresses.

Alternative growing media are needed to overcome the shortage of top soil which generally occurs in oil palm nursery. Organic waste such as vegetables, food and rice straw is one of the ingredients that can be used as a growing medium because it is easy to find and has a high nutrient content. These wastes need to be decomposed to make them more easily absorbed by plants, therefore it is necessary to add bioactivators such as Trichoderma sp. for speed up the decomposition process. The purpose of this study are to obtain alternative growing media for organic waste, determine its effect on oil palm seedlings, and determine the best growing media treatment. This research conducted at experiment areal in Cibitung, from November 2021 until August 2022. This research was arranged in non factorial block complete design with four treatments, consist of P0 (kontrol sub soil), P1 (50% vegetable waste+50% sub soil+Trichoderma sp.), P2 (50% food waste+50% sub soil+Trichoderma sp.) dan P3 (50 rice straw+50% sub soil + Trichoderma sp.). Every treatments repeated 3 times and have 3 samples, so there were 36 seeds. The data was analysis of variance, if test result was significant at 5%, then continued by BNT. The results showed that organic waste could be used as alternative growing media for oil palm nursery, and significantly effected to plant height (3 MAP), stem diameter (2 and 3 MAP), leaf area and biomass. The best treatment based on morphological and physiological response is rice straw and Trichoderma sp.

The long apple cultivar is in increasing demand in the markets thanks to its unique shape, aroma, and its endemic and delicious taste. This study aimed to determine the physical and chemical changes throughout the fruit development, which indicates its optimum harvest time. Fruit samples were collected every two weeks from the last week of May to the middle of October. The fruit harvest time was evaluated depending on different quality note attributes including physical, mechanical, chemical, physicochemical, and pomological properties. The weight, fruit size, sphericity, color, soluble solids content, pH, firmness, elasticity, phenolic content (gallic acid and catechin), and organic acids (citric acid and ascorbic acid) were analyzed. Throughout the ripening period, fruit weight, fruit size, sphericity, and SSC gradually increased. There was a negative correlation between organic and phenolic contents and harvest dates. The optimum harvest time of Kagizman long apple was approximately 18 weeks after the full bloom.
COMPARISON OF A NOVEL VACUUM-COMBINED INFRARED AND HOT-AIR CONVECTION METHODS FOR DRYING OF DEVECI (PYRUS COMMUNIS L.) PEAR SLICES

Published: July 2023

In this study, the quality characteristics of pear slices dried in vacuum-combined infrared dryer equipped with a two-way infrared heating (100-300 W infrared power) and convectional dryer (40-70 °C) were comparatively investigated. Increasing infrared power in vacuum-combined infrared dryer decreased the drying time.  However, the differences between vacuum pressures (100 mmHg and 250 mmHg) were generally negligible. Drying process at 200 and 300 W IP under vacuum was approximately 2- and 2.5-times shorter than conventionally drying at 55 and 70 °C, respectively. Although a very low amount of HMF in dried pear slices by the conventional dryer was detected only at 70 °C after 300 min, high amounts of HMF was detected at 300 W after 120 minutes. The rehydration rate of pear slice dried with vacuum-combined infrared dryer was higher than those of pear slice dried with conventional dryer. Syringic, chlorogenic and ellagic acids were identified in dried pear samples. Chlorogenic acid was found to be the most among phenolic compounds in dried pears. While the ellagic acid was not detected in fresh pear, dried pears had ellagic acid content (8.14-16.93 mg/kg d.m.). It was found that total phenolic content, ABTS and DPPH values of dried pears by vacuum-combined infrared dryer was lower than those of dried sample by conventional dryer. The pear slices dried at 300W and 250 mmHg had the highest sensory scores. The results show that the vacuum-combined infrared drying provided a shorter drying time and better sensory quality for dried pear compared to conventional drying.
MAXIMUM ACTIVE POWER TRANSMISSION EFFICIENCY AND POWER FACTOR DEFINITION IN HYBRID SYSTEMS WITH ARBITRARY WAVEFORMS
Authors: Hernán Emilio Tacca
Published: July 2023

Based on a theorem giving the maximum available active power with constant transmission losses valid for arbitrary waveforms it is possible rigorously generalize the definitions of power factor based on the definition of apparent power as the maximum power available. Then it could be applied to systems with non-symmetric, non-sinusoidal, and eventually time-varying (ie non-periodic) waveforms or DC grids. By this way, the application may be extended to hybrid multi-wire systems with asymmetrical phases, with different voltages, frequencies or waveforms (i.e. non-sinusoidal waves, such as rectangular or PWM) and even DC, which can be combined eventually sharing the neutral conductor.

Published: July 2023

The present work investigates the thermal treatment of alumina powder with a purpose built oxygen-Liquefied Petroleum Gas torch, as a of low-cost alumina microsphere production process. In this dry process, irregularly shaped alumina particles are re-melted, acquiring a spherical shape due to surface tension. Microspheres of the stable alpha alumina phase were produced starting from two different alumina powders, both having a granule size of approximately 80 µm. In one case the initial granules are formed of micrometric crystalline particles while in the other the crystalline particles are nanometric. In both cases the resulting microspheres present similar surface texture and the predominant crystalline phase is ?-alumina. Microspheres smaller than 42 µm show a dendritic morphology on the surface with minor presence of ?-alumina. In contrast, microspheres larger than 103 µm present a smoother surface with rhombohedral grains and presence of ?-alumina.
