Authors: Masendra Masendra , Aristo Verick Purba Brandon , Irawati Denny , Lukmandaru Ganis
Published: April 2023

Dalbergia latifolia wood is a beautiful wood with color of dark purple to dark brown and rich in flavonoid compounds. This study aimed to investigate the presence of flavonoid compounds from D. latifolia wood and their contribution to its color. The D. latifolia wood sample was powdered and extracted with ethanol-toluene (1/2, v/v). The ethanol- toluene extract then was column chromatographed to obtain fraction 1 to fraction 12. Methylation was conducted to each fraction to detect flavonoid compounds by GC-MS. The results of GC-MS analysis showed that ethanol- toluene extract gave Fr- 1- Fr. 3 as soluble flavonoids (34.2%) and Fr. 4- Fr. 12 as insoluble polymers (62.6%). Furthermore, 12 flavonoids i.e latifolin, dalbergiphenol, chalcone, dalbergin, and their derivatives were characterised and these compounds might be significance in contributing to color of D. latifolia wood.

Rapid assimilations of O3 observations – Part 1: methodology and tropospheric O3 changes in China in 2015–2020
Authors: Zhu Rui , Tang Zhaojun , Chen Xiaokang , Jiang Zhe , Liu Xiong
Published: April 2023

Abstract. The high computational cost of chemical transport models (CTMs) is a potential bottleneck for the rapid assimilation of ozone (O3) observations. Here we developed a single tracer tagged-O3 mode to build the capability of the GEOS-Chem model for rapid simulation of tropospheric O3. The tagged-O3 mode demonstrates high consistency with GEOS-Chem full-chemistry simulation and dramatic reductions in computational costs by approximately 91–94 %. The tagged-O3 simulation was combined with China Ministry of Ecology and Environment (MEE) and Ozone Monitoring Instrument (OMI) O3 observations to investigate the changes in tropospheric O3 over E. Asia in 2015–2020. The assimilated O3 concentrations demonstrate good agreement with O3 observations: surface O3 concentrations are 42.9, 41.8 and 42.1 ppb; and tropospheric O3 columns are 37.1, 37.9 and 38.0 DU in the simulations, assimilations and observations, respectively. The assimilations indicate rapid increases in surface O3 by 1.60 (spring), 1.16 (summer), 1.47 (autumn) and 0.80 (winter) ppb yr-1 over E. China in 2015–2020, and the increasing trends are underestimated by the a priori simulations. More attention is thus suggested to the rapid increases in O3 pollution in spring and autumn. Furthermore, we find stronger increases in tropospheric O3 columns over highly polluted areas, which may reflect the larger contributions of local emissions. The large discrepancy in the trends in tropospheric O3 columns by assimilating surface and satellite observations further indicates the possible uncertainties in the derived free tropospheric O3 changes. The rapid O3 assimilation capability is a useful tool for the extension and interpretation of atmospheric O3 observations.
Local moisture recycling across the globe

Published: April 2023

Abstract. Changes in evaporation over land affect terrestrial precipitation via atmospheric moisture recycling and, consequently, freshwater availability. Although global moisture recycling at regional and continental scales is relatively well understood, the patterns of local moisture recycling and the main variables that impact it remain unknown. We calculate the local moisture recycling ratio (LMR) as the fraction of evaporated moisture that precipitates within a distance of 0.5∘ (typically 50 km) of its source, identify variables that correlate with it over land globally, and study its model dependency. We derive the seasonal and annual LMR using a 10-year climatology (2008–2017) of monthly averaged atmospheric moisture connections at a scale of 0.5∘ obtained from a Lagrangian atmospheric moisture tracking model. We find that, annually, an average of 1.7 % (SD of 1.1 %) of evaporated moisture returns as precipitation locally, although with large temporal and spatial variability, and the LMR peaks in summer and over wet and mountainous regions. Our results show that wetness, orography, latitude, convective available potential energy, wind speed, and total cloud cover correlate clearly with the LMR, indicating that wet regions with little wind and strong ascending air are particularly favourable for a high LMR. Finally, we find that spatial patterns of local recycling are consistent between different models, yet the magnitude of recycling varies. Our results can be used to study the impacts of evaporation changes on local precipitation, with implications for, for example, regreening and water management.
Reconciling ice dynamics and bed topography with a versatile and fast ice thickness inversion
Authors: Frank Thomas , van Pelt Ward J. J. , Kohler Jack
Published: April 2023

Abstract. We present a novel thickness inversion approach that leverages globally available satellite products and state-of-the-art ice flow models to produce distributed maps of subglacial topography independent of bed observations. While the method can use any complexity of ice physics as represented in ice dynamical models, it is computationally cheap, enabling applications both on local and large scales. Using the mismatch between observed and modelled rates of surface elevation change (dh/dt) as the misfit functional, iterative pointwise updates to an initial guess of bed topography are made, while mismatches between observed and modelled velocities are used to simultaneously infer basal friction. The final product of the inversion is not only a map of ice thickness, but a fully spun-up glacier model representing the dynamic state of a given glacier. We here present the method, and use an artificial ice-cap built inside a numerical model to test it and conduct sensitivity experiments. Even under a range of perturbations, the method is stable and fast. Finally, we apply the approach to the tidewater glacier Kronebreen on Svalbard. Ultimately, our method shown here represents a fast way of inferring ice thickness where the final output forms a consistent picture of model physics, input observations and bed topography.

Industrial and Clean Energy Hydrogen : An Overview
Authors: Kumar Chaturvedi Aravind
Published: April 2023

Global warming has several adverse impacts on climate and if not contained, may result in rising of sea level to a dangerous point when millions will be required to be displaced and rehabilitated. It is also responsible for climatic changes. Green house gases are the reason behind global warming. Carcon dioxide is main green house gas which is added due to continuing use of fossil fuels. To obtain carbon neutrality and Decarbonization, need of the hour is clean and carbon free source of energy. Hydrogen has emerged as a clean fuel as it does not contain carbon. But hydrogen does not occur in pure form in nature and eventually it has to be manufactured. Conventionally, it is manufactured from fossil fuels such as natural gas or coal and process is called steam reforming. This also requires source of energy. Use of fossil fuel results in green house gas. Hydrogen can also be produced by electrolysis of water and source of energy can be renewable energy like solar or wind energy. This obviates adding of greenhouse gas and is a clean process. There are several ways of producing hydrogen depending on raw input and source of energy, which quantify to what extent the produced hydrogen is green. Hydrogen offer variety of applications across many segments of industry. It is worthwhile to evaluate all manufacturing processes and applications of Hydrogen and its potential contribution in Decarbonization.
A Predictive Evaluation of the Relationship Between Operation Workforce Prerequisites Sustainable Development

For instance, poor education leads to a high unemployment rate in isolated rural regions. Students from various areas get education but not educational chances, which is the biggest difficulty that regional youth confront today. Most rural employees have just one way to improve their lives or income, and that is via education, but they lack the necessary knowledge, skills, and ability to do so due to a lack of educational options. A pleasant learning environment empowers all students to be economically productive, to create sustainable development, to contribute to free and stable societies, and to increase individual wealth. Unqualified education is a trap for all students. You never know what people will pay for it in the future. It's preferable to be alphabetical rather than allegedly talented and jobless. In India, poor schooling results in poor learning outcomes. Supply chain management is the administration of the flow of goods and services, and it includes all procedures that turn raw materials into completed products. The use of knowledge, statistical methodologies, and machine learning technologies to forecast future events based on previous data is known as predictive analytics. The major purpose of this article is to examine current human resources, forecast future needs and availability, and take measures to ensure that the supply of people and skills meets demand.
How to Write History?
Authors: Coulmas Florian
Published: April 2023

78 years after the annihilation of Hiroshima, a G7 summit is scheduled to take place in Hiroshima. That both representatives/heirs of the victims and the victimisers of the first nuclear strike in human history will sit there around the same table is ample reason to reflect on the way this event is and should be remembered. Recalling some details of the bombings of Hiroshima and Nagasaki, this text recalls that the bombs did not, as is often thought, bring about Japan’s surrender in World War II and touches upon the contingency of history writing. It also recalls that it was common practice for a long time to refer to the “nuclear holocaust” and raises the question of whether and how present-day circumstances – in particular the fact that the 2023 G7 summit takes place in times of a war not anticipated by many just a year ago – do and should influence the perception and evaluation of past facts and thus their sedimentation in history.

Published: April 2023

Global competitiveness is based on the serious matter of the work attitude of employees because it is dependent on how well companies train their work force. With the advent of technology, it is important to investigate and improve the employee attitude towards work with the inclusion of technological upgrades for humans through training. Training may differ from one organization to the next in the form of on-the-job and off-the-job training. Training paved the way for the type of attitude employees have towards their work. Skill labor's positive view towards work is substructure on advanced training methods that make them differentiate in work place competition. Researchers first make thematic analysis in the form of code data segments with the help of MAXQDA 2020 software. After activation of all inserted interviews, researchers conducted the mixed-method analysis. A single-case analysis was framed for theme identification with the help of thematic analysis. After that, thematic coding was framed for content analysis. For identification, screening, and intent, PRISMA was employed. A coded frequency matrix was assimilated to depict the functionalism of training in the study area in the form of bibliographic analysis. Systematic evaluation of the interview text manifested that training is considered by most employees as the initial point of skill development and an extended part of positive work attitude development, resulting in enhanced organizational performance in textile industries. Study outcomes based on the positivism approach will inform policy recommendations because of its objectivity.

The modern game of rugby is characterized by the multitude of motor actions specific to this game. Unlike other sports games, the actions of scoring points in this game are completely different and have their specificity, which is expressed by touching the ball within the boundaries of the front line of the opponent's court. Apart from that, there are a lot of possibilities to score points in a match using other actions, either with the arms or with the foot. So far no one was able to send in the perfect solution, that is not strange. This article proposes for analysis the modalities, quality and quantity of points scored in a match at senior level. This allowed the coaches to optimize the training process of rugby athletes to increase the number of points scored in one match or another.

Published: April 2023

Physical deficiency represents any deviation from normal in the form and physiological functions of the body, which disturbs the normal growth and harmonious development of the body, changes its external appearance, reduces its physical and even intellectual abilities, as well as the ability to work. These deviations from normal can change the shape of the body and its physical functions completely or only at the level of some segments and regions. The most common conditions encountered in primary school students are platypodia, lordotic back, kyphotic back and scoliosis. Every year, the number of children with attitude deficiencies is constantly increasing, having a negative effect on the general state of health. Kinetoprophylaxis is considered as part of medical kinesiology and constitutes an axiom in medical sciences. Kinetic therapy and kinetoprophylaxis are based on own means and working means from physical education. That's why an important role in physical education is the directing of the child's growth process, in the formation of a healthy body. Particular attention is paid to physical qualities, aiming at: the development of the body's physiological capacity, the harmonious physical development of the child, the development of motor skills, the formation of hygienic and sanitary skills, the correction of physical deficiencies, that is, the aim is to optimize the biological development of the human being. Physical exercise is a means of working in kinetoprophylaxis.

Authors: SARİDEMİR Demet , DOĞRU Volkan , AVANAZ Ali , YAPRAK Muhittin , GÜRER Sezer
Published: April 2023

Giriş: Covid-19 geleneksel genel cerrahi asistan eğitim programlarında alışılagelmedik değişikliklerin yaşanmasına sebep olmuştur. Akdeniz Üniversitesi Hastanesi Genel Cerrahi Kliniği'nin 6 yıllık asistan eğitimi geçmişinin incelendiği bu çalışma, pandemi sonrası karın duvarı fıtıkları için yapılan eğitimsel işlemlerin trendlerindeki değişiklikleri ortaya koymayı amaçlamaktadır.

Yöntem: Batın duvarı fıtığı endikasyonu ile 18 Eylül 2014 ve 17 Eylül 2020 tarihleri arasında kliniğimizde gerçekleştirilen cerrahi prosedürlerin kayıtları incelenmiş Covid-19 etkisindeki dönem, geçmiş yılların trendleri ile karşılaştırılmıştır.

Bulgular: Toplamda gerçekleştirilen 2587 prosedürün 2330’unda (%90) cerrahi ekipte en az 1 asistan katılımı olduğu görülmektedir. Umblikal fıtıklar dışında asistan katılımı olan prosedür sayılarında Covid-19 sonrası anlamlı bir düşüş olmamış; beklenen aylık medyan umblikal prosedür sayısı 5.6 iken gerçek değerin 1.0 olduğu anlaşılmıştır (sırasıyla ÇAA 5.3-6.0 ve 0.0-3.0; p=0.041). İnguinal fıtıklarda operatörlük (sırasıyla, 16.9 ±2.1 ve 9.8 ±5.6; p=0.017) ve eğitici asistan görevi üstlenen asistanların sayısında (sırasıyla, 4.0 ±0.8 ve 1.8 ±1.8; p=0.025) belirgin düşüşler olmuştur.

Sonuç: Covid-19 pandemisi daha çok cerrahi ekipteki görev dağılımını etkilemiştir. Bu dönemde eskiye göre daha kıdemsiz asistanlar batın duvarı fıtıklarında yardımcı cerrah pozisyonunda görevlendirilmişlerdir. Fıtık cerrahisine giriş niteliği taşıyan umblikal fıtıkların Covid-19’dan en çok etkilenen eğitsel prosedürler olduğu ve telafi edilmeleri gerektiği anlaşılmıştır.

Aim: There has been a steady increase in the number of elderly patients with end-stage renal disease (ESRD) receiving renal replacement therapy (RRT). We aimed to compare the efficiency and complications between individual and family member-assisted PD in a patient group with geriatric ESRD.

Method: This retrospective study included 50 patients > 65 years of age who received CAPD treatment between 2017-2019 in the peritoneal dialysis unit. Before dialysis modality selection, patients' functional status was evaluated with the 6-item activities of daily living (ADL) and 8-item instrumental daily living activities (IADL). Their three years’ follow-up results were evaluated in terms of dialysis efficiency parameters and dialysis complications.

Results: There was no statistical difference between the two groups regarding their age, gender, and biochemical data. There was also no difference between edema, exit-site infection, and leakage; however, a significant difference was observed between the total number of peritonitis and the time until the first peritonitis attack. The time until the first peritonitis attack was shorter in the APD group than in the other group. Besides, the number of total peritonitis attacks was higher in the assisted PD group.

Conclusion: The elderly ESRD population is increasing, and PD use is declining worldwide. However, if APD is not done well, it may not be an effective strategy to reverse this decline and provide safe and successful treatment to many frail, elderly patients.

Published: April 2023

Spontaneous pneumomediastinum is a rare disease that develops due to alveolar rupture. Many cases with pneumomediastinum, related to Corona Virus Disease-19 (COVID-19) have been reported so far, but most of these patients had severe disease and extensive parenchymal damage. Pneumomediastinum is fairly rare in COVID-19 with such a little lung infiltration. It is supposed to occur as a result of the increased intra-alveolar pressure induced by an excessive cough. Here, we present a patient with asthma with typical symptoms of COVID-19 on chest computerized tomography (CT) and focal ground-glass opacity and pneumomediastinum, which spontaneously regressed without cardiac or respiratory complications.

Customary communities with nature-based livelihoods have ways of knowing and living with their environment that they are best situated to manage. One example of such a group that lives in coastal and small island areas is the semi-nomadic Bajau people. At present, most of them have been sedentary in coastal areas and several Marine Protected Areas (MPA) such as Wakatobi National Park (WNP). They are rarely incorporated into the MPA management system. This research aims to investigate the transitional pattern of co-management in MPA from the view of the Bajau as a maritime-oriented people. This ethnographic study was carried out in five Bajau villages in WNP, Southeast Sulawesi, Indonesia. Interviews and participatory mapping were employed as research methods among related stakeholders to explore the many perspectives on these issues. WNP is starting to put the concept of co-management into practice, yet they face several challenges. However, Bajau communities there face cultural degradation and institutional complexities in inter- and intragroup relations, especially in promoting coastal and marine management. The documented pillars of the Bajau community indicate socio-ecological constraints on their involvement in the co-management transition of WNP. Administration, governance, sustainable resource management, capacity building, locality, and other issues can be addressed via a participatory model, but there will be difficulties to resolve on many levels for this model to prove optimally effective. To justify the need for WNP, Bajau sacred areas as part of traditional ecological knowledge have the prospect of being incorporated into marine co-management schemes.

Siderophores are the low-molecular weight secondary metabolites which have a strong preference for ferric iron and are generated by bacteria when they are exposed to iron stress. Iron is a vital nutrient which is required for the various cellular processes such as electron transport but due to aerobic conditions most of the iron becomes unavailable as surface iron get oxidized into oxyhydroxide polymers and free iron get reduced. Siderophores have clinical, environmental as well as agricultural applications. Clinical applications involve anticancer activity, anti-malarial activity and also help to remove transuranic elements and in agriculture, various types of siderophores help in the promoting the growth of some plant and enhance the uptake of Fe which leads to increase the plant yield and also protect plants from pathogens. Environmental applications involve the binding of the toxic metals such as Pb2+, Cd2+, Hg2+etc, with siderophores which helps in heavy metal bioremediation. The purpose of this review is to explore about siderophores, their varieties, and their uses.

Solar energy is the major renewable energy source in the world. In the world energy use scenario, solar energy has occupied second position and it’s share in renewable energy is 27.5 per cent. In India, solar energy is first position in renewable energy capacity and it’s share in renewable energy has 33.5 per cent. Solar photovoltaic is conversion of solar energy into electricity which can be used for solar water pumping. With the above background of the present study is attempted to focus on the impact of solar and electric operated tube well irrigation in the sample farms. A quota sampling selection procedure and snow ball sampling technique were used for this study. A sample size of 45 each of solar and electric operated sample farmers altogether 90 sample respondents were contacted for the conduct of this research study. Garrett’s ranking technique was used for assessing the merits and demerits of solar and electric operated tube well irrigation as opined by the sample respondents. It was observed that free electricity for motor pumping was the prime most important attribute which influenced the farmers preference for electric energy followed by efficiency in lifting water from higher depths with good discharge rates. The foremost bothering issue in electric energy use was the limited hours of 3 phase electric power availability and frequent voltage fluctuations. The availability of huge subsidy component in the initial investment and reduction in the energy bill were the foremost important reasons for the adoption of solar power motor pumps in irrigation. The foremost bothering issue in solar energy use for irrigation was unavailability of battery for power store which was expressed as the major drawback in solar energy irrigation pumping. To promote the large scale adoption of this important renewable energy all the merits of this energy source expressed by the farmers should be widely propagated among the farming community. The demerits in the use of existing devices of this energy source such as battery for storage, efficiency improvements with higher horse power’s should be addressed by gearing up the Research and Development wing to focus on these issues expressed by the farmer stakeholders.

Globally organic farming is well known and appreciated. Due to continuous use of synthetic fertilizers, the harmful elements enter into the food web and ultimately cause health hazard not only to human beings but also have a detrimental effect on environment. In this regard the demand for organic produce is gaining momentum for safe and healthy food. The present study explains the “Effect of rice and wheat varieties on rice equivalent yield, system productivity and nutrient uptake under organic farming in Jharkhand”. A field experiment was conducted at research farm of Birsa Agricultural University, Jharkhand with an objective to evaluate yield and nutrient uptake of rice and wheat varieties which are influenced by organic farming. The soil of experimental plot was sandy clay loam in texture having average carbon (6.16 Kg/ha), nitrogen (254.78 kg/ha), phosphorous (39.59 Kg/ha) and potassium (208.26 Kg/ha) with soil pH 6.04. Field experiments were carried out using randomized block design replicated thrice involving twelve treatments with twelve varieties. Rice varieties are: T1: Birsa vikas Dhan 203, T2: Birsa Dhan 201, T3 : Birsa vikas Sugandha 1, T4 : B.V.D 110, T5: Sahbhagi, T6: Birsamati, T7: Anjali, T8: Lalat, T9: M.T.U. 1010, T10: Akshay, T11: Pusa Sugandha and T12: Naveen. Whereas, wheat varieties are : Raj 4250, GW 366, NW 2036, K 0307, K 9107, HI 1563, Raj 4229, DBW 14, WR 544, BG 3, HD 2733 and DBW 39. Results showed: both the grain yield (40.22 kg/ha) and straw yield (62.96 kg/ha) of rice were maximum in MTU 1010. Likewise, the grain yield (31.56 kg/ha) and straw yield (45.78 kg/ha) of wheat were maximum in K 0307 and Raj 4229 respectively. The best rice equivalent yield of wheat was found maximum (33.19 q/ha) in B.V.D. 110-K 0307 cropping system, both the system productivity (66.52 Rs./ha) and system production efficiency (28.18 kg/ha/day) were highest in MTU 10101-WR 544 rice-wheat cropping system. Highest nutrient uptake in grain (N-53.33 kg/ha, P-11.31 kg/ha and K-10.20 kg/ha) and in straw (N-37.77 kg/ha, P-7.42 kg/ha and K-71.53 kg/ha) were observed in MTU 1010 rice variety. K0307 recorded highest nutrient uptake in wheat grain (N-47.93 kg/ha, P-8.74 kg/ha and K-10.06 kg/ha), however nutrient uptake in wheat straw (N-24.41 kg/ha, P-6.84 kg/ha and K- 38.40 kg/ha) was obtained maximum in Raj 4229.

Background: Pigeonpea is an important protein-rich legume and one of the potential crops for rainfed agriculture in many parts of the semi-arid tropics. Worldwide, India ranks first both in area and production. Despite that, the productivity levels in India are low because of various biotic and abiotic stresses, out of which Sterility mosaic disease (SMD), which is caused by Pigeonpea Sterility Mosaic Virus (PPSMV), is a severe constraint during crop production. In the context of the above facts, resistant breeding is one of the most economical and eco-friendly approaches. The present investigation aimed to identify microsatellite markers linked to SMD resistance and potential resistant genetic resources. In this field- laboratory investigation carried out during 2017-2018, thirty genotypes and susceptible check ICP 8863 were evaluated in a randomized block design (RBD) with two replications in SMD sick plots. Observations were recorded based on visual symptoms for SMD incidence, and percent disease incidence (PDI) was calculated. In addition, a molecular study for the same genotypes was carried out with a total of 20 SSR markers. Out of 20 SSR primers, only 16 were amplified, from which only a single SSR marker (AHSSR20) showed polymorphism while the remaining 15 were monomorphic. The marker AHSSR20 have the potential to discriminate resistant and susceptible genotypes. AHSSR 20 primer assign 160 bp bands in resistant genotypes viz., BDN-711, PT-04-281, and PT-704-1-2 while ever, 172 bp bands assign in susceptible genotypes viz. ICP-8863, PT-04-378, PT-012-20, and PT-016-3. Accordingly, we conclude that AHSSR20 is a potent marker that can be helpful to discriminate between susceptible and resistant genotypes and can be used for direct selection of resistant genotypes during early segregating generation and marker-assisted breeding.

Published: April 2023

La pérdida prematura de molares inferiores permanentes es frecuente, ya que por su período eruptivo está más tiempo en contacto con el ambiente ácido bucal, siendo muy susceptibles al ataque de las caries debido a su morfología oclusal que favorece el acúmulo de placa dentobacteriana y si existe una higiene bucal deficiente sería la causa principal de la pérdida dentaria. La inclinación mesial de molares que sigue a la pérdida de dientes vecinos, provoca problemas estéticos, funcionales y periodontales, por lo que la terapia para la verticalización molar mejora las condiciones del diente afectado. Objetivo: determinar la influencia del cantiléver en la verticalización de molares mesioinclinados después de una pérdida dentaria. Materiales y Métodos: el presente trabajo es de tipo descriptivo, diseño cuantitativo. Se elaboró un instrumento (Encuesta) cuya validación fue realizada por 2 expertos con base en el coeficiente de Kendall (W) midiendo los criterios de suficiencia, claridad, coherencia y relevancia. Se realizó un muestreo aleatorio por conveniencia determinando a 13 especialistas en Ortodoncia, docentes del programa de Especialización de Ortodoncia en la Universidad de Guayaquil. Resultados: un 53,84% de los profesionales manifiesta que siempre es importante que el cantiléver genere fuerzas leves y constantes durante su desactivación. Un 38,46% manifiesta la incomodidad al paciente como desventaja del cantiléver. Un 38,46% visualiza trauma oclusal y pérdida prematura de pieza vecina como consecuencia de la inclinación molar, de acuerdo a los parámetros que toman en cuenta al elegir la técnica para verticalizar un molar, un 53,84% considera el grado de inclinación del diente. Un 69,23% considera que el arco TMA ofrece mejores condiciones para la elaboración del cantiléver. Conclusión: al elegir la técnica para verticalizar un molar se debe considerar el grado de inclinación del diente, el tejido de soporte, el biotipo facial y el tipo de movimiento requerido.
