Réel étrangéisé et roman de l’étrangéisation
Authors: PEJOSKA Frosa
Published: March 2023

Certains événements produits par l’histoire du XXe siècle sont si « irréels », si « fantastiques », qu’aucune imagination n’aurait pu les inventer. Cette réalité paraît imaginaire : un réel-non-réel. La réalité a été étrangéisée, rendue étrangère. Les faits, de par leur incroyable réalité, sont devenus fiction. Il suffit à l’écrivain de leur donner une forme artistique et de les « imaginer » en utilisant les faits authentiques comme matériau brut. Grâce à l’imagination, il crée une nouvelle forme, une forme littéraire, une faction-fiction (documentaire-imaginaire), selon Danilo Kiš (1995). Aussi ces événements réels, parce qu’ils paraissent irréels, deviennent-ils « littéraires ». Et le réel, devenu fiction, apparaîtra dans toute sa réalité étrangéisée. Ma réflexion portera sur la perception, la réception et l’écriture de ces événements étrangers inouïs, imprévisibles puisque ne relevant pas du connu ne peuvent pas être reconnus.
A propos de la littérature brève
Authors: BORS Edit
Published: March 2023

Pour susciter l’attention du lecteur, les microrécits intègrent l’imprévisible, entre autres, dans le ton adopté, dans la structure narrative choisie ou dans l’hybridation générique. Leur réception est aussi liée à des conditions restreintes : en peu de temps et avec peu de mots, le microrécit fait de l’effet ou passe complètement inaperçu. Aussi trouve-t-on des récits qui nous font rire ou pleurer et qui nous poussent à nous interroger sur nos habitudes de lecture.
Caméléon de la littérature

À travers des siècles aussi bien qu’aujourd’hui, on peut observer que si le pastiche et la parodie apparaissent à un moment décisif, c’est pour signaler un renouvellement d’ordre général. Dans le cadre de notre contribution, nous nous limiterons à réorganiser nos connaissances en la matière par rapport aux questions de définition. Nous allons traiter ces pratiques d’écriture en termes de prévisible et imprévisible en prenant en considération leurs traits caractéristiques.
How I learned to hate you. Parasocial interactions in echo chambers and their spillover effects
Authors: Radu Raluca-Nicoleta
Published: March 2023

This article analyzes the most influential posts on Facebook related to COVID-19, for the first two years of the pandemic, to explain how parasocial opinion leaders created echo chambers, in the Romanian public sphere, and to discuss the cumulative spillover effects these echo chambers had on society at large. A database of the 233,242 most influential posts in Romanian about COVID-19, from the first two years of the pandemic, is investigated using a mixed methods approach, to 1) verify statistically if issue-related echo chambers existed and 2) to describe, qualitatively, how they functioned. A special focus is devoted to trolling in the form of reactions to posts, such as haha reactions for messages about COVID-related deaths. Using the literature on parasocial interaction, inoculation theory, online disinhibition effect and echo chambers, the article shows how echo chambers supported trolling behavior, for radicalized Facebook users, how they polluted the public discussion and how they made dialog impossible for social groups that ended up identifying each other as the enemy. Based on these research results, the author proposes two policy recommendations for social platforms.
Did #METOO advance the feminist movement in China? A typical Chinese case study of sexual harassment. Impact of power relations and morality
Authors: Deng Yuying , Chen Rui
Published: March 2023

The #METOO campaign sparked worldwide attention to the issue of sexual harassment in 2017. Shortly afterward, sexual harassment cases also followed in Chinese universities. This study uses framing theory and content analysis, analyzing typical case news reports after the rise of the #METOO movement. Firstly, the study showed that Chinese news media mostly reported with social frame and individual frame, and seldom used the gender discrimination frame. Secondly, Although Chinese media actively promoted the progress and solution of sexual harassment cases, they mainly solved the problem from the perspective of power relations and failed to continue to dig into the problem of sexism. However, the way of reporting from the perspective of power relations may further influence the teachers’ image in China and even bring negative stereotypes.

Published: March 2023

Más duro a la larga que romper una espiral del silencio puede resultar, para el individuo o para la civilización, someterse a los actuales procesos de control social. Así lo ha entendido el periodista británico Douglas Murray, quien, a sus polémicos ensayos La extraña muerte de Europa (2017) y La masa enfurecida (2019), ha añadido recientemente, en La guerra contra Occidente (2021), una tercera y muy meticulosa reflexión sobre las principales retóricas del discurso antioccidental, redondeando con ella, en fondo y contexto, los motivos de sus obras anteriores.
Desigualdad de género y violencia en los videojuegos: un análisis desde las experiencias videolúdicas de la juventud
Authors: Calderón-Gómez Daniel , Gómez-Miguel Alejandro
Published: March 2023

En las últimas décadas, hemos asistido a la consolidación de los videojuegos como una de las principales fuentes de ocio de la juventud. Sin embargo, a partir del auge de los videojuegos online multijugador, basados en la competitividad y el anonimato, también han surgido prácticas de odio, violencia y hostigamiento que afectan a la experiencia de juego de los jugadores y, especialmente, de las jugadoras. Por ello, en este artículo se analizan las actitudes, experiencias y percepciones de jugadores y jugadoras de videojuegos desde una perspectiva de género, entre las que destacan experiencias de violencia, intimidación y acoso, especialmente en juegos online. Se plantea una metodología cuantitativa mediante una encuesta a una muestra representativa de 1200 jóvenes entre 15 y 29 años y un plan de análisis basado en el análisis factorial de componentes principales, análisis de conglomerados y análisis multivariante de varianza. Como resultados principales, se destaca una mayor preferencia comparativa de las mujeres hacia juegos de un solo jugador y una mayor propensión a ocultar su identidad en juegos online. Además, las situaciones de acoso e intimidación están muy generalizadas entre los jugadores online y en el caso de ellas afectan especialmente a las que juegan con mayor frecuencia a videojuegos.
Mikrodalga ile Kurutulmuş Kereviz Yapraklarının (Apium graveolens L.) Kuruma Hızının ve Bazı Kalite Parametrelerinin Belirlenmesi
Authors: KÖMÜŞ Esra , SARI Ferda
Published: March 2023

Bu çalışmada kereviz yaprakları (Apium graveolens L.) mikrodalga tekniği ile kurutulmuştur. Mikrodalgada kurutma işlemi 180, 360, 600 ve 900 W mikrodalga çıkış gücünde yapılmıştır. Uygulanan farklı mikrodalga çıkış gücünün kereviz yapraklarının kuruma kinetiği, toplam fenolik madde içeriği, antioksidan kapasite, klorofil a, b ve toplam klorofil miktarı üzerine etkileri incelenmiştir. Kereviz yapraklarının kuruma davranışlarını açıklamak için Page, Newton ve Weibull olmak üzere 3 farklı model test edilmiştir. Uygulanan tüm koşullarda Page modelinin kereviz yapraklarının farklı mikrodalga çıkış gücünde kurutulmasında kuruma kinetiğini açıklayan en iyi model olduğu görülmüştür. Kereviz yapraklarının kurutulması azalan hız periyodunda gerçekleşmiş olup uygulanan mikrodalga çıkış gücünün artmasıyla kuruma oranı artmış ve kuruma süresi azalmıştır. Kurutulan kereviz yapraklarının toplam fenolik madde içeriği ve antioksidan kapasitesi 180, 360 ve 600 W uygulamasında taze örneğe göre azalırken 900 W’da artmıştır. Uygulanan tüm mikrodalga çıkış güçleri kereviz yapraklarının klorofil a, b ve toplam klorofil içeriğinde taze yapraklara göre azalmaya neden olmuştur. Bu azalma en yüksek 180 W’da en düşük ise 900 W’da tespit edilmiştir.

Authors: ÖZTEP Ruken , IŞIN Ferruh
Published: March 2023

Antep fıstığı (Pistacia vera) uluslararası ticarette önemli bir paya sahip, çerezlik olarak tüketilen, tatlı ve şekerleme sanayisinde kullanılan sert kabuklu bir meyvedir. Gelecek dönemlerde Antep fıstığı üretim miktarının tahmin edilmesi hem sürdürülebilir tarımsal planlamanın yapılabilmesi hem de tarım politikalarının gerçekçi olarak saptanabilmesine yönelik üretim öngörüsü ile ilgili çalışmaların yapılması gerekmektedir. Bu çalışma FAO ve TÜİK’ten elde edilen 1961-2021 dönemine ait 61 yıllık verilerden yararlanarak 2022-2026 dönemine ait Türkiye Antep fıstığı üretimini öngörmeyi ve öneriler geliştirmeyi amaçlamaktadır. Antep fıstığı için üretim öngörüsünde Box-Jenkins’in ARMA modelinden yararlanılmış olup, en uygun istatistiksel sonuçlar ARMA (2,3) modelinden elde edilmiştir. Model sonuçlarına göre, Türkiye’nin 2022 yılında Antep fıstığı üretiminin 2021 yılına göre %58.93 artarak 189.697 tona ulaşacağı öngörülmüştür. Antep fıstığı üretiminin 2023 ila 2026 yıllarında sırasıyla 130.100, 168.100, 105.982 ve 132.166 ton olarak gerçekleşeceği öngörülmüştür. Öngörü yapılan yıllarda periyodisiteden dolayı üretim ve verimde bir istikrarsızlığın yaşanacağı anlaşılmaktadır. Bu durumun önüne geçilebilmesi için periyodisite eğilimi düşük olan çeşitler tercih edilmeli, Türkiye’de yaygın olarak uygulanan kıraç ve taşlık arazide yetiştiricilik yerine sulama imkânı olan araziler tercih edilmeli ve sulu koşullarda üretim yapılmalıdır.
Melissa officinalis: Antibacterial and Antioxidant Potential, Phenolic Profile and Enzyme Activities
Authors: ULGEN Canan , YILDIRIM Arzu , TURKER Arzu
Published: March 2023

Popularly referred to as lemon balm, Melissa officinalis L., has been used as a cure for gastrointestinal disorders, respiratory and cardiovascular diseases, mental and central nervous system problems, various cancers, headache, nervousness, and rheumatism. In this study, the phenolic profile, antioxidant potential, antibacterial activity, and enzyme activity of lemon balm grown in nature in Bolu, Turkey were determined. Furthermore, comparisons were made with plants grown in vitro. Individual phenolic analysis with HPLC-DAD showed that the most prevalent phenol was rosmarinic acid in both extracts and naturally-grown plants had higher amount than in vitro-grown ones. Similarly, naturally-grown plants had considerably greater levels of total phenol-flavonoid, scavenging activity for free radicals (DPPH), and phenol synthesis related enzyme (PAL). As for the enzymatic antioxidant activity (SOD and CAT), naturally-grown plants were found to have higher CAT activity and lower SOD activity. As a remarkable result, although plants grown in vitro showed moderate antibacterial activity, no effect was observed in naturally-grown plants. In general, these results showed that the M. officinalis grown in nature is exposed to more biotic and abiotic stress and increases their phenolic content remarkably and consequently antioxidant capacity.
Entansif Yetiştiricilikte Bir İnekte Paramphistomosis Olgusu ve Klinik Değerlendirme
Authors: ÖZÜİÇLİ Mehmet , YAVUZ Ahmet , YAVAŞ Özkan , ÇIRAK Veli
Published: March 2023

Paramphistomosis, Paramphistomidae ailesinde yer alan parazitlerin evcil ve yabani ruminantlarda oluşturdukları enfeksiyondur. Parazitlerin biyolojileri gereği enfeksiyon meraya çıkan hayvanlarda daha sık görülür. Subklinik seyirli enfeksiyonlar verim kayıplarına neden olabileceği gibi, şiddetli klinik enfeksiyonlarda ölümler görülebilir. Entansif sistemde bakılan ve ölüm sonrası nekropside Paramphistomosis teşhisi konan bir ineğe ait bu olgu araştırıcıların, veteriner hekimlerin ve yetiştiricilerin konuya dikkatlerini çekmek amacıyla sunulmaktadır. Düve dönemi sonrası hiç meraya çıkmamış, altı yaşlı, Holstein ırkı bir ineğin ölüm sonrası yapılan nekropsisinde rumenden 2434, retikulumdan 1322 adet olmak üzere toplam 3756 adet Paramphistomidae etkeni toplanmıştır. Histopatolojik incelemelerde her iki organda mukozada hiperkeratoz ve akantotik alanlarla beraber mononükleer hücre infiltrasyonları saptanmıştır. Bu olguyu dikkat çekici kılan en önemli husus, hayatının büyük bir kısmını “kapalı sistemde” geçiren bu hayvanın, “mera kaynaklı” bir paraziter enfeksiyona (Paramphistomosis) yakalanmış olmasıdır. Bu bağlamda, “entansif besleme şartlarında bakılan hayvanlarda iç parazit olmaz” genel kanısının aksine “koruyucu hekimlik” konseptine uygun olarak en azından yılda bir defa endoparaziter enfeksiyonlar (özellikle helminthosis) yönünden klinik ve laboratuvar muayeneler yapılmasının faydalı olacağı düşünülmektedir.

Published: March 2023

Bu çalışmada kuzu rasyonlarına artan seviyelerde alternatif bir kaba yem olarak düşünülen Evelik (Rumex acetosella) otunun, Yonca kuru otu (Medicago sativa) yerine %0, 10, 20 ve 30 oranlarında ikame edilmesinin gaz üretimi (GÜ), metan üretimi (CH4), gerçek sindirilebilir kuru madde (GSKM), partitioning factor (PF), mikrobiyal protein (MP), mikrobiyal protein sentezi etkinliği (MPSE) ve gerçek sindirim derecesi (GSD) üzerindeki etkileri belirlenmiştir. Rasyonların gaz üretimi ve sindirim dereceleri in vitro gaz üretim metodu ile tespit edilmiştir. Yapılan çalışmada gaz üretimi, GSKM, PF, MP, MPSE ve GSD miktarları artarken CH4 üretimi azalmıştır. Gerçek sindirilebilir kuru madde, PF, MP, MPSE ve GSD değerleri istatiksel olarak anlamlı bulunmuştur (P<0.05). Çalışmada GSKM, PF, MP, MPSE ve GSD değerleri sırasıyla 253.22 ile 315.86 mg, 2.84 ile 3.33, %57.42 ile %107.59, %22.68 ile % 34.04 ve %53.13 ile %66.49 arasında değişmiştir. Rasyonların Pearson korelasyon analizi, GSKM ile GÜ ve % CH4 üretimleri arasında negatif bir ilişki bulunmuştur (P<0.05). Gerçek sindirilebilir kuru madde, PF, MP ve MPSE arasında pozitif bir ilişki tespit edilmiştir (P<0.01). Mevcut çalışmanın sonuçları esas alınarak evelik otunun kuzu rasyonlarında kullanımı için uygun dozun belirlenmesi oldukça zor görülmektedir. Bunun için Evelik (Rumex acetosella) otunun kuzu performanslarına etkilerini belirlemek için in vivo denemelere ihtiyaç vardır.

Estimating maternal mortality and identifying causes of maternal deaths in Jammu and Kashmir: a two-year epidemiological study
Authors: Rehman Saleem Ur , Jeelani Asif , Luthra Anup
Published: March 2023

Background: An accurate estimate of the maternal mortality ratio and its underlying causes is crucial for the effective planning of maternal health services. The aim of the study was to estimate the maternal mortality ratio (MMR) and identify causes of maternal deaths in Jammu and Kashmir. A subnational geographical area in India.
Methods: The study included maternal deaths from April 2020 to March 2022 among residents of Jammu and Kashmir. We enumerated all maternal deaths and recorded their socio-clinical parameters from interviews with family members. The cause of death was inferred from the medical records and verbal autopsy. Live births data for the corresponding period was obtained from the routine health management information system. We calculated the maternal mortality ratio using a standard formula.
Results: A total of 185 maternal deaths and 3.97 lakh live births were recorded over the two-year study period. It translated into an MMR of 47 per lakh live births, exhibiting noteworthy variability between districts. Postpartum haemorrhage (PPH) and hypertensive disorders of pregnancy accounted for a substantial proportion of maternal deaths, representing 44.3% (82/185) of cases. Sepsis and other obstetric complications were identified as the cause of death in 15.7% (29/185) and 19.5% (36/185) of maternal deaths, respectively. Furthermore, the majority of maternal deaths occurred among women between 25-30 years of age. Approximately two-thirds of maternal deaths occurred during the post-partum period.
Conclusions: In summary, our study reveals that the maternal mortality rate (MMR) in Jammu and Kashmir falls below the sustainable development goal target, albeit with marked inter-district variability pointing to disparities in healthcare delivery. We recommend expanding the coverage of evidence-based interventions aimed at reducing the incidence of postpartum haemorrhage, eclampsia, and other obstetric complications to improve maternal health outcomes.

Authors: Naqash Ashfaq Ahmad , Nayak Bilal Ahmad , Wani Shahid Bashir , Teli Mohamad Ashraf
Published: March 2023

Background: Gastrointestinal (GI) cancers are one of the common cancers and are associated with significant morbidity and mortality. The present study was conducted to evaluate the treatment outcome of GI cancer patients undergoing follow-up in the oncology OPD of a tertiary care hospital.
Methods: Cases previously treated for any GI cancer at one center and coming for follow-up to the hospital were enrolled. Treatment outcome was ascertained in these patients and its relationship with clinical and demographic characteristics of patients at diagnosis were analysed.
Results: A total of 68 cases of GI cancers were enrolled with a mean age of 57.44±8.3 years and of 39 (57.35%) were males. The most common site for cancers was oesophagus, stomach, Colo-rectal with 22,20 and 17 cases respectively. Stage II was the most common stage at presentation in 50% cases followed by Stage III in 32.35% of cases. There was significant association between stage at diagnosis with stage I disease at diagnosis significantly related to complete cure. Site of cancer, age and smoking history had no significant correlation with treatment outcome.
Conclusions: Diagnosis of GI cancers at early stage was associated with complete cure at follow up. This finding demonstrates the importance of early screening for GI cancers and the need to have robust screening guidelines and improving access to screening with highly valid tests particularly for individuals with high risk features.

Published: March 2023

The term "expanded dengue syndrome" was introduced to describe the severe clinical manifestations that result from dengue fever (DF), namely severe multi-organ involvement including disorders of the nervous system. Neurological complications occur in 1-5% of dengue patients, including haemorrhagic stroke. A 68-year-old man presented with complaints of full-body convulsions for 1 minute. Four days earlier the patient complained of headache, fever, and nausea. Non-contrast CT scan of the head showed abnormal hyperdense lesions with focal intraparenchymal oedema in the frontoparietoocipital region, cortical sulci and gyri appeared dilated, ventricular system and sisterna were dilated. Anti-dengue IgG and IgM were positive. Neuropathogenesis that may play an important role in dengue-related neurological syndromes include direct CNS invasion by the virus, autoimmune reactions, and metabolic changes. The diagnosis of neurological complications related to dengue haemorrhagic fever (DHF) requires special attention, especially for areas where DF is still endemic.

Published: March 2023

COVID-19 is a global health concern with varying severity. Moderate to severe cases require isolation for 10-20 days, and those with weakened immune systems (like HIV) should isolate for 20 days. Indonesia has a rising number of HIV cases. HIV-positive individuals have a higher risk of COVID-19 and may have lower antibody levels after vaccination. Two case studies of HIV-positive patients who contracted SARS-CoV-2 are presented. In case 1, a 29-year-old patient who received the COVID-19 vaccine and was on antiretroviral therapy was hospitalized three times with worsening symptoms, and unfortunately did not survive. In case 2, a 46-year-old patient with a history of tuberculosis and also on antiretroviral therapy was hospitalized twice, reporting mild symptoms, and did not experience any further symptoms related to COVID-19 after being discharged. Both patients tested positive for COVID-19 using rapid antigen tests and PCR tests and did not report any history of contact with COVID-positive individuals. These case studies highlight the challenges faced by HIV-positive individuals in managing COVID-19, and the need for continued research in this area. Immunocompromised COVID-19 patients need special isolation, even with mild symptoms. Longer isolation periods may be necessary, as studies show positive tests can still mean infectiousness. Viral culture tests can help identify contagious individuals who test positive on PCR tests. People with HIV may need a COVID-19 booster vaccine due to lower antibody levels after the initial vaccine. Further research is needed to develop antiviral treatments for COVID-19 infection in individuals with immunocompromised.

Published: March 2023

Meralgia paresthetica (MP) or so-called as lateral femoral cutaneous nerve (LFCN) entrapment is a mononeuropathy characterized by a localized area of paresthesia, dysesthesia, tingling, burning, and numbness on the anterolateral aspect of the thigh, between the inguinal ligament and the knee without associated loss of reflexes and motor weakness. The incidence of MP increases with obesity and diabetes. Ultrasound-guided has been demonstrated useful for visualization of peripheral nerves, in particular very small nerves such as the LFCN. Hereby, we reported a case of 63-year-old man diagnosed with MP. The patient complained of numbness, and no pain when pinched in his anterolateral aspect of the left thigh since 3 weeks ago. On physical examination, his body mass index (BMI) was 27 (overweight) with normal vital signs. Neurological examination revealed normal motoric function and refleks; but decreased sensation to pinprick in the left anterolateral thigh in the LFCN distribution. No abnormal findings on plain radiographs of the pelvis and lumbar spine. Ultrasound-guided injection was performed in this patient.

Despite the increasing prevalence of mental health disorders, access to mental health care remains a challenge, especially in low and middle-income countries. The use of mobile apps has the potential to improve access to mental health care and promote self-awareness and well-being. The study aims to design a mental health application that incorporates journaling and mood tracking to promote mindfulness and encourage individuals to regularly reflect on their experiences and emotions. The application is built on the firebase platform and utilizes three key components: firebase storage, firestore database, and firebase authentication. The application also employs two native device features, camera and storage, for capturing profile pictures and cover images. The study provides a comprehensive solution for user management and the delivery of mental health support services.
Climate change mitigation with carbon capture: An overview
Authors: Towoju Olumide A , Petinrin Moses O
Published: March 2023

The world is at the verge of catastrophe occasioned by the effect of climate change. Drastic action needs to be taken to reverse this ugly trend. Some of the proffered solutions to global warming is the adoption of renewable energy usage and a stop of fossil fuels combustion. However, the low capacity factor and energy return has been the bane on the usage of some renewable energy sources. A leeway however, exists in the technology of removal of greenhouse gases referred to as Carbon Capture. The widely adopted method being at point source because of its high concentration favouring easier processes of removal. This technology has received increased attention over the years as evident from data for the past five years. However, this technology alone cannot guarantee atmospheric CO2 levels required to maintain global temperature rise below the 1.50C mark. Negative emission technology processes of which the Direct Air Capture (DAC) is one needs to be developed. The infancy of the DAC technology and the uncertainties that surrounds its cost still pose as challenges. The cost of removing a tonne of CO2 with DAC technology can be as high as $600, this is unsustainable and has to be drastically reduced. While it is projected that DAC technology can take out 980 Metric Tonne (MT) CO2/annum by 2050, current figures stand at 0.008 MT. It is our view that the development of solid adsorbents and the harnessing of the thermal energy inherent in the sun can be a game changer.

In quest of a stimulant to cope with rather challenging activities, some individuals take to the consumption of Cola nitida. The most active ingredient, caffeine, could be responsible for the physiological or clinical effects of Cola nitida in humans. Such a practice could culminate in the abuse of the said substance. Caffeine might alter hormonal profiles and thereby affect menstrual function, which might have a direct bearing on fertility. Amongst other factors, testosterone and progesterone are important to the chances of fertility in the humans. Besides, it has been well documented that the probability of pregnancy is reduced by 5% per unit of body mass index exceeding 29 kg/m2 . From some published evidences of the high prevalence of infertility nowadays, the need for this study was thereby necessitated. Here we report the influence of Cola nitida on testosterone and progesterone concentrations in the normal weight humans under resting condition in Ambrose Alli University. Twenty (20) normal weight volunteers (10 males and 10 females) and non-habitual Cola nitida chewers, aged 18-28 years were used for the study. 0.5g/kg body weight of Cola nitida was administered to each subject to be chewed as a bolus. After ingestion, 50ml of water was given to each volunteer to flush the masticated Cola nitida down the gut. The subject was allowed to rest for 90 minutes. Blood sample was collected from the medial cubital vein using vacutainer syringe. The radio-immunoassay principle was used for the estimation of testosterone and progesterone levels. The results showed that Cola nitida consumption by the normal weight male and female subjects significantly (P<0.05) reduced serum level of progesterone in the females (from 16.47±039 ng/ml to 4.690±0.592 ng/ml) and serum testosterone level in the males (from 7.392±0.479 to 4.727±0.466 ng/ml). We show that Cola nitida, at the specific dosage, could reduce the chances of fertility in both the male and female normal weight subjects.
Methods for controlling temperature of the instrumentation equipment using the contour heat pipe
Authors: Borschev N.O.
Published: March 2023

The paper considers two ways of maintaining temperature of the instrumentation equipment: using the heat pipes equipped with thermoelectric cooling plate on the compensation cavity and the control valve installed at the outlet of the evaporating radiator. Since the temperature of the contour heat pipe is mainly controlled by the temperature of the compensation cavity positioned behind the evaporator, maintaining the high-precision temperature mode of this device is an urgent task for the entire spacecraft thermal regime. In the first method, the evaporating radiator is heated or cooled depending on the plate device polarity. In the second, the compensation chamber temperature could be changed using the steam supplied to the compensation cavity by a regulator installed at the outlet of the evaporator. Temperature control using a valve is due to the fact that the steam of the working fluid enters the bellows under pressure, which depends on the temperature in the evaporator. Pressure difference between steam and gas causes the bellows to contract and expand, while the valve associated with it partially closes the openings in the housing, through which the steam enters the condenser and the compensation cavity. Detailed description of these devices operation is provided, and thermal hydraulic models of the contour heat pipes equipped with these two devices are compiled.
Dynamic balance generalized problem and the promising areas of its application
Authors: Gorobtsov A.S.
Published: March 2023

The paper considers the generalized problem of the machines and mechanisms dynamic balance in terms of ensuring the given laws of altering reactions in the selected links. Representation of equations of the mechanical systems dynamics in the form of differential algebraic equations was used making it possible to obtain mathematical models of the nonlinear mechanical systems dynamics with the arbitrary structure of kinematic and force connections. With this approach, the constraint reactions are determined by algebraic equations from the system coordinates. The problem solution is based on changing the bonds selected reactions due to the impact on reactions in the other selected bonds by adding non-stationary terms to the selected bonds equation. Conditions for rigorous solution of the optimal control problem for a mechanical system are shown for the integral quality criterion not explicitly containing the control functions. The method is aimed at numerical models of the mechanical systems widely used in the programs for dynamic analysis of the coupled systems of bodies. Test examples are provided for manipulator, anthropomorphic robot and controlled suspension of a transport vehicle. The method was realized in the software package for simulating the controlled motion dynamics of the coupled systems of bodies.
Justification of the method for production of the 2NiCuMn 38-2V alloy bars to manufacture parts for the electrovacuum devices working area
Authors: Golovkin P.A.
Published: March 2023

The paper considers critical features of the chemical composition of the 2NiCuMn 38-2V alloy bars material, which could affect vacuum purity of the electrovacuum devices working area. Taking into consideration peculiarities of the electrovacuum devices manufacture technology, it is shown that the use of cold-drawn bars in manufacturing parts of their working area is technically unreasonable. It is noted that instead of the cold-drawn bars, bars obtained by hot rotational forging could be used.

The paper considers possibilities of the digital technologies to control and manage each stage of the product lifecycle. The main software systems used to control and manage the product lifecycle at various stages are provided. Based on analyzing a number of scientific publications, assessment was made of the implementation level of such software products at each stage of the product lifecycle, and advantages of their introduction are presented. It is noted that mechanical engineering is the leader in implementing the appropriate digital technologies. The other industries are just adapting the previously developed technologies to specific conditions of the production process. However, certain issues of using modern digital technologies, in particular the blockchain, in relation to separate stages of the product lifecycle are still insufficiently studied. The basis of a new digital technology to control, manage and support the product lifecycle was developed, i.e. technology for selecting and transforming the necessary information into the product digital environment, in particular, in the mechanical engineering products in general. The essence of the proposed technology is briefly stated. Main differences from the existing blockchain technologies are listed regarding efficiency (since the software is constantly updated with more advanced versions) and incomplete data availability, which is due to maintaining the required level of security.

Published: March 2023

The article presents the results of modeling and determining the influence of the parameters of reverse surface plastic deformation on the geometric characteristics of the plastic imprint and the pressure in the contact zone of the working tool under static and reverse impact. Using the software for 3D design SOLID WORKS-2019 and computational modeling in ANSYS-19.1, a finite element model of the contact zone was built to determine the geometric characteristics of the plastic indentation and the contact pressure between the working tool and the surface of the workpiece, depending on the geometry of the working tool, reversing frequency its rotation, the initial angle of installation and the amplitude of the angle of reverse rotation of the working tool. Based on the obtained results, to increase the pressure in the contact zone of the working tool with the workpiece, which affects the degree of hardening and smoothing of microroughnesses of the workpiece surface and the formation of compressive residual stresses, it is recommended to use the following parameters and hardening modes: working roller with a diameter of 20–30 mm, with a profile radius of 2 –2.5 mm, distance between tops of working roller profile 1.5–2 mm, initial installation angle of the working roller 90о, amplitude of the reverse rotation angle of the working roller ±6 – ±8о and reverse speed of the working roller 200–240 double strokes/min.

Countless combinations of sizes and shapes of the flow path could ensure the specified flow rate and pressure ratio of the axial compressor stage. Programs based on the mathematical models are an effective tool in initial design and preliminary selection of the optimal option. The RROK-GPD-22 software program is briefly being described, it solves the problem on the basis of the pressure loss model and deflection capacity of the A. Komarov lattice, theoretic rigorous calculation of oblique and direct shocks, as well as empirical equations and coefficients. Models were checked by comparison with data on the Rotor 37 NASA test stage. Stages were calculated with different ratio of the cross-sectional area at the outlet of the impeller to that at its inlet and stages with the hub-tip ratios of 0.400 ... 0.728 with different swirl at the impeller inlet. Results are provided in determining the hub-tip ratio influence on the efficiency, pressure ratio and specific stage performance.

Reducing mass of the launch vehicle components structure to increase the payload mass launched into orbit is one of the main areas in developing the space services market. Modern designs of the launch vehicles require extremely high fuel mass fraction, which necessitates introduction of the low-density materials. Fuel tanks could count for 70...80% of the total product volume, which results in the development of tanks for the cryogenic fuel obtaining decisive importance in design and development of the new type of launch vehicles. Introduction of the composite materials in designing a cryogenic fuel tank makes it possible to lower its mass by 30% compared to a reference aluminum tank, which, accordingly, allows increasing the inserted payload mass. Review of the methods used in manufacturing the cryogenic composite fuel tanks is presented. Liner manufacturing technology and its material are proposed, taking into account the temperature difference during shaping and its interaction with the cryogenic fuel. Composite material and method for manufacturing the composite tank are selected. Design calculation of the composite cryogenic tank was carried out.

The present investigation was carried out during 2015-2016. The change was analyzed for a period of 10 years (2005 to 2015). Landsatoperational land imager (OLI) and thematic mapper (TM) satellite images (of 30 m resolution) of the years 2015 and 2005 were used.Mapping was performed on a 1:50,000 scale using ArcGIS software, and for image enhancement, ERDAS imagine software was used.Extensive Ground Truthing was employed to supplement accuracy assessment and a total of 133 ground truth points were taken fordata collection. The overall classification accuracy of the mapping was 92.48% and the Kappa coefficient was 0.87. The study area wasdelineated via visual image interpretation technique into 10 LULC classes viz., forest, forest scrub, agriculture, grassland, snow, waterbody,horticulture, wasteland, and agroforestry respectively. The forest cover density map was classified into three classes on the basis of crowndensity viz., Closed Forest, Open Forest and Forest Scrub. Furthermore, two additional classes grassl and non-forest were also delineated.The results obtained from change analysis were used to identify the drivers of forest cover change using a close-ended semi-structuredinterview schedule. The responses were assigned scores for the ranking of drivers using statistical analysis. The comparison of maps of2005 and 2015 revealed that the total forest area has reduced by 0.48% from 2005 to 2015. The area under agriculture has declined by0.87% during the same period. Horticulture has shown an increase of 0.8% during the decade. It was also found that the area underClosed Forests reduced by 1.05% from 2005 to 2015 while Open Forests, forest scrub, and grassland increased by 0.57 %, 0.27% and0.08% respectively. In terms of area, conversion of Closed Forest into Open Forest 851.48 ha), Closed Forest into Forest Scrub (104.77ha), and Open Forest into Forest Scrub (33.26 ha) ascribed to forest degradation whereas conversion of 111.42 ha, 59.87 ha and 26.61ha of land from closed forest, forest scrub and open forest into non-forest can be attributed to deforestation.

Abiotic stresses due to changing environmental conditions and intensive agriculture are causing soil salinity and sodicity leading tosoil deterioration. It directly affects nutrient availability and uptake and reduces plant productivity. The microorganisms are known toimprove the availability of nutrients in the soil and therefore, the present work aimed to maximize the use of applied fertilizers and boostthe productivity. The effects of the Trichoderma mixture (TrichoMix) and NPK on plant growth and rice yield in degraded land underfield conditions was studied. The abiotic stress tolerant Trichoderma strains comprising of T. koningiopsis (NBRI-PR5) and T. asperellum(NBRI-K14) were used in the treatments (i) Control (Cont.), (ii) NPK, as per recommended dose (NPK100%) (iii) Trichoderma mixture (NBRIPR5+NBRI-K14) (TrichoMix) (iv) TrichoMix + NPK50%. Significantly higher plant growth and yield (6.57q/h) was obtained in TrichoMix+NPK50% treatment. The improvement in rice production in the treatment TrichoMix +NPK50% was ascribed to the significant changes insoil physiochemical characteristics such as water holding capacity (35%), bulk density (40%), total organic carbon (42%), available N(39%), P (44%), K (48%) and microbial biomass carbon (88%). The results conclude that the mixture of T. koningiopsis (NBRI-PR5) and T.asperellum (NBRI-K14) may be recommended as sodic soil amendment to increase plant growth and yield in combination with chemicalfertilizers to support rice cultivation.

Angiosperms demonstrate a surprisingly frequent phenomenon of variability in the gross pollen morphological characteristics. In thepresent study, we recorded and described a new aperture in the pollen grains of Schleichera oleosa (Lour.) Oken, a monotypic genusof the soapberry family Sapindaceae, from Madhya Pradesh, central India, based on the LM and CLSM observations. This condition istermed the tetra-zono-parasyncolporoidate condition. A new pollen aperture has been recorded in this monotypic genus with theusual one (tri-zono-parasyncolporoidate condition), and this phenomenon of the occurrence of a new with increased number of pollenaperture is known as pollen aperture heteromorphism. The study will further help identify this taxon from the sedimentary archives asone of the indicators of the warm and humid (moist) climate and increased monsoonal rainfall.

An experiment under microcosm was conducted to assess the allelochemical potential of Mikania micrantha on the growth andgermination of Lactuca sativa through a pot culture experiment. Soil samples were collected from two different sites i.e., M. micranthainvaded soil (for the experimental pot) and healthy forest soil (for control pot). Various seed germination and growth parametershave been analyzed to evaluate the inhibitory and stimulatory effects of the allelochemicals released from M. micrantha. The resultsrevealed that the germination and growth parameters of the crop were inhibited and suppressed by M. micrantha. Out of the fifteenseeds planted in both pots, thirteen seeds were able to germinate in the experimental pot, while fourteen were in the control pot. Theseedling height (8.85 cm), shoot length (8.75 cm), seedling biomass (0.408 g), vigor index (0.52), root length (0.091 cm), germinationpotential (0.73), germination percentage (86.66%), germination index, (3.66) and germination rate index (317.17) were lower in theexperimental pot and higher in the control pot. Therefore, M. micrantha showed an inhibitory effect on the growth and germination ofL. sativa and induced negative allelopathic effects.
An Indigenous Method of Cremation in Earthen Containers as a Sequel to Disaster Resilience: A Case Study of Kusheshwarsthan Wetland Area in Darbhanga District of North Bihar
Authors: Jha Vidyanath
Published: March 2023

The paper takes into account an indigenous adaptation for cremation in the extreme flood situations in the Kusheshwarsthan East C.D. block of Darbhanga district in north Bihar. With no dry land all around in the vicinity, people have no option other than raising a bamboo platform on which 6 to 8 fit high mud container (Kothi) is placed inside. The dead body is put in a squatting position. The fuels includedegrained maize cobwebs, dung cakes, wood splits of mango and desi ghee (clarified butter). Sugar crystals are added to invigorate the flames of the pyre. Wooden boats are hired to ferry the dead body as well as the mourners to the cremation place. Almost a decade-long practice of using degrained maize cobwebs as cremation fuel is an example of resilience during extreme flood disasters. At the same time insistence on using mango wood also for burning a dead body speaks of people's adherence to this plant, even during extremities.
