PENGARUH PENAMBAHAN BIOAKTIVATOR EM-4 TERHADAP PRODUKSI BIOGAS DARI LIMBAH CAIR INDUSTRI TAHU
Authors: Muzakki Jamiluddin Ahmad
Published: December 2021

Tofu industrial waste is generally divided into two forms of waste, namely solid waste and liquid waste. The liquid waste of the tofu industry contains organic material that can be decomposed anaerobically into methane gas (CH4), other gases, and water which is commonly called biogas. One of the potential biocatalysts as a source of microorganisms in biogas production is Effective Microorganisms 4 (EM-4). This research was conducted by adding EM-4 with a concentration of 0.5%; 1%; and without EM-4 into 15 liters of tofu liquid waste in the digester for fermentation for 7 days. Observation of the pressure on the manometer seen from the difference in the height of the liquid manometer U and the combustion process was carried out on the 7th day (constant pressure). The maximum pressure of biogas for 7 days at 1% EM4 of 927,864 kg/m.s2 produces a blue flame, has an unpleasant odor, does not cause smoke with a fire height of 12,602 mm. So it can be concluded that the greater concentration of EM-4 used, the greater the pressure of biogas and fire
REACTION IN GOVERNMENT AND PARLIAMENT OF GREAT BRITAIN ON SOVIET-ESTONIAN PEACE NEGOTIATIONS IN 1919-1920
Authors: Kochegarov S. A. , Mikhailov V. V.
Published: December 2021

The article focuses on the contradictions in the British regarding the continuation of military operations against the Soviet Republic at the end of 1919 and the participation of Estonia in the White struggle. Documents of British archives, and transcripts of proceedings of Parliament shows that after a series of military setbacks of the White forces, and the failure of formation with the direct pressure from the British military advisers of the government of the North-West Russia to create anti-Bolshevik coalition under the political control of the British commissioners in the Baltic countries, the mood in Parliament and the War Cabinet of Britain has changed. Speeches of liberal members of Parliament at the meetings of 1919-1920, note that the issue of concluding a Bolshevik-Estonian peace Treaty has become positively evaluated in wide circles of British society. Criticism of the «militarism» of the government became particularly acute after the peace of Tartu in January 1920, and the firmness of the Estonian government, which had making peace, was welcomed by a number of deputies. Minutes of meetings of the British Imperial War Cabinet and documents of the War Council also shows a shift from the policy of active involvement of the Baltic countries in the anti-Bolshevik struggle to recognition of the failure of this struggle and the impossibility of its revival by spending the financial and material resources, which were strongly necessary to solve other problems that arose in the British government after the end of the First world war.

One of the consequences of the Great Reforms of Alexander II was the radical transformation of the Russian Imperial Army. At the same time, the development of social thought in Russia created the conditions for the penetration of social democratic propaganda into the soldier’s environment. As a result, the moral and psychological state of soldiers and discipline in the Russian army began to decline steadily at the turn of the century. Understanding of this problem stimulated the military department to make significant efforts aimed at working with personnel. However, due to a number of reasons, the planned results were not fully achieved.
Emergence of Synthetic Cannabinoids as Drugs of Abuse
Authors: Nupur Joshi  , Mahipal Singh Sankhla
Published: December 2021

Cannabis has been the most commonly used drug throughout the world for centuries. The psychoactiveproperties of cannabis are largely attributed to Δ9-tetrahydrocannabinol or THC, the active psychoactiveingredient in the cannabis plant. Lately, new psychoactive substances (NPS) have appeared that aremostly ruled by cathinone’s and synthetic cannabinoids (SCs). SC’s have emerged as drugs of abusebecause of their ability to mimic the euphoric effects of THC. Sprayed on natural herb mixtures, theywere initially sold as ‘herbal incense’ or ‘herbal smoking blends’ as substitutes for cannabis. Thesesynthetic drugs became popular as ‘legal highs’ under brand names such as Spice, K2, Mojo and manyothers in the early 2000’s. SC’s stimulate the same CB1 and CB2 receptors as THC but they are linkedto higher toxicity in terms of duration and severity than cannabis. This is because SC’s act as directagonist of cannabinoid receptors, whereas THC being a partial agonist. Reports suggest that SC’s areassociated with a range of undesired pulmonary, cardiovascular, gastrointestinal effects. Long term SCuse is also linked to severe cognitive deficits. With the global rise in use of SC products, it is importantto develop and validate the screening procedures and investigate the toxicological and pharmacologicalaspects and risk factors associated with its use and abuse.

Published: December 2021

The number of people registered with health insurance schemes has increased from 161.2 million(2011-12) to 335 million(2016-17), which is two-fold in just 5 years.1 As per the forecasts regarding the increase in healthcare insurance market in India, it is evident that the hospitals have to face the management of patient costs through the insurance schemes in large numbers as the number of claims will increase eventually. With the present condition of schemes reimbursing the claims with a huge time lag of about 3-4 months, the hospital have to carry the burden of opportunity costs lost on these claims.2 This indicates the responsibility hospital administration should have to face the ever increasing claims and manage them without incurring loss. This study was intended to do a cost analysis between surgical procedures performed under two categories, Aarogyasri Health Insurance Scheme, A Government Sponsored Health Insurance Scheme in the state of Andhra Pradesh and Cash category, where patients do not hold any insurance policy and pay by cash all the hospital expenses. On the basis of revenue generated the top 15 procedures under Insurance scheme are determined and costing is done using Activity Based Micro Costing method. Costing is done for the determined 15 procedures under both the categories of payment modes. The results are compared to evaluate the economic impact of the health insurance scheme on hospital.

El objetivo del estudio es valorar el impacto de un programa online de intervención de Mindfulness y Compasión en Profesionales Sanitarios en relación con el bienestar y el cansancio emocional realizado mediante un estudio prospectivo controlado (de cohorte) de diseño aleatorizado mediante un muestreo probabilístico. Se incluyeron los treinta y dos profesionales sanitarios (médicos, enfermeros y fisioterapeutas) que trabajaron en España durante el estado de alarma de la pandemia de la covid-19. Se presentó una intervención en forma de taller virtual acerca de la práctica de mindfulness en tres cohortes. Uno de ellos de forma síncrona, otro de forma asíncrona y un grupo control al que se le enviaron prácticas de relajación de la misma duración que el taller de mindfulness. El programa se realizó en un período de ocho semanas. Se enviaron recordatorios semanales y mensajes estimulantes de la práctica. Se midieron los niveles de mindfulness y burnout mediante dos cuestionarios antes y después de la intervención. Como resultados se obtuvo una disminución en los factores que inciden sobre el burnout, como el agotamiento emocional y un aumento en el nivel de realización personal. Los niveles de mindfulness mediante FFMQ-E aumentaron de manera global de 122.5 a 128.7. Como conclusión, el grupo síncrono mostró un descenso del cansancio emocional y un mayor nivel de proceder con atención plena, factores que pueden incidir en el burnout de este colectivo.

Authors: Guadalajara Sergio
Published: December 2021

El cuco común (Cuculus canorus) posee diversas significaciones simbólicas en la tradición cultural europea. Entre ellas, quizás la más frecuente es la que describe a esta ave como heraldo de la primavera. Este artículo presenta un estudio comparado de la simbología asociada al cuco en la literatura clásica y las letras castellanas. Todo ello permitirá analizar la utilización alegórica de esta ave en dos de las composiciones más conocidas de Alcuino de York (el Versus de cuculo y el Conflictus Veris et Hiemis), en las que ocupa una posición central. Se ofrece, asimismo, la primera traducción al castellano de ambos poemas.

En esta larga nota se sitúa el ciclo de Guiron de Courtois en su contexto de la literatura francesa del siglo xiii dedicada a la materia de Bretaña. El interés de este extensísimo ciclo va más allá, pues es el eslabón necesario con la rica tradición italiana iniciada por Rustichello de Pisa. De forma inexplicable, el Ciclo había quedado inédito aunque era conocido por los estudiosos. El análisis de esta edición crítica revela la utilidad de la aplicación del método «neolachmanniano» y la riqueza que conlleva, al establecer el «manuscrito de superficie» que permite un acercamiento riguroso a los posibles orígenes de cada una de las partes que constituyen la narración.
Deep Capsule Network for Facial Emotion Recognition
Authors: Salem Tegani , Abdelmoutia Telli
Published: December 2021

Although the classification of images has become one of the most important challenges, neural networks have had the most success with this task; this has shifted the focus towards architecture-based engineering rather than feature engineering. However, the enormous success of the convolutional neural network (CNN) is still far from comparable to the human brain's performance. In this context, a new and promising algorithm called a capsule net that is based on dynamic routing and activity vectors between capsules appeared as an efficient technique to exceed the limitations of the artificial neural network (ANN), which is considered to be one of the most important existing classifiers. This paper presents a new method-based capsule network with light-gradient-boosting-machine (LightGBM) classifiers for facial emotion recognition. To achieve our aim, there were two steps to our technique. Initially, the capsule networks were merely employed for feature extraction. Then, using the outputs computed from the capsule networks, a LightGBM classifier was utilised to detect seven fundamental facial expressions. Experiments were carried out to evaluate the suggested facial-expression-recognition system's performance. The efficacy of our proposed method, which achieved an accuracy rate of 91%, was proven by its testing the results on the CK+ dataset.

A Novel Approach to Asteroid Impact Monitoring
Authors: Roa Javier , Farnocchia Davide , Chesley Steven R.
Published: December 2021

Orbit-determination programs find the orbit solution that best fits a set of observations by minimizing the root mean square of the residuals of the fit. For near-Earth asteroids, the uncertainty of the orbit solution may be compatible with trajectories that impact Earth. This paper shows how incorporating the impact condition as an observation in the orbit-determination process results in a robust technique for finding the so-called virtual impactors, i.e., the regions in parameter space leading to impacts. The impact pseudo-observation residuals are the b-plane coordinates at the time of close approach and the uncertainty is set to a fraction of the Earth radius. The extended orbit-determination filter converges naturally to an impacting solution if allowed by the observations. The uncertainty of the resulting orbit provides an excellent geometric representation of the virtual impactor. As a result, the impact probability can be efficiently estimated by exploring this region in parameter space using importance sampling. The proposed technique can systematically handle a large number of estimated parameters, account for nongravitational forces, deal with nonlinearities, and correct for non-Gaussian initial uncertainty distributions. The algorithm has been implemented into a new impact-monitoring system at JPL called Sentry-II, after undergoing extensive testing. The main advantages of Sentry-II over the previous Sentry system are that Sentry-II can systematically process orbits perturbed by nongravitational forces and that it is generally more robust when dealing with pathological cases. The run times and completeness of both systems are comparable, with the impact probability of Sentry-II for 99% completeness being 3 × 10−7.

Particle Reacceleration by Turbulence and Radio Constraints on Multimessenger High-energy Emission from the Coma Cluster
Authors: Nishiwaki Kosuke , Asano Katsuaki , Murase Kohta
Published: December 2021

Galaxy clusters are considered to be gigantic reservoirs of cosmic rays (CRs). Some of the clusters are found with extended radio emission, which provides evidence for the existence of magnetic fields and CR electrons in the intra-cluster medium. The mechanism of radio halo (RH) emission is still under debate, and it has been believed that turbulent reacceleration plays an important role. In this paper, we study the reacceleration of CR protons and electrons in detail by numerically solving the Fokker–Planck equation, and show how radio and gamma-ray observations can be used to constrain CR distributions and resulting high-energy emission for the Coma cluster. We take into account the radial diffusion of CRs and follow the time evolution of their one-dimensional distribution, by which we investigate the radial profile of the CR injection that is consistent with the observed RH surface brightness. We find that the required injection profile is nontrivial, depending on whether CR electrons have a primary or secondary origin. Although the secondary CR electron scenario predicts larger gamma-ray and neutrino fluxes, it is in tension with the observed RH spectrum for hard injection indexes, α < 2.45. This tension is relaxed if the turbulent diffusion of CRs is much less efficient than the fiducial model, or the reacceleration is more efficient for lower-energy CRs. In both the secondary and primary scenario, we find that galaxy clusters can make a sizable contribution to the all-sky neutrino intensity if the CR energy spectrum is nearly flat.
Fallback Accretion Halted by R-process Heating in Neutron Star Mergers and Gamma-Ray Bursts
Authors: Ishizaki Wataru , Kiuchi Kenta , Ioka Kunihito , Wanajo Shinya
Published: December 2021

The gravitational wave event GW170817 with a macronova/kilonova shows that a merger of two neutron stars ejects matter with radioactivity including r-process nucleosynthesis. A part of the ejecta inevitably falls back to the central object, possibly powering long-lasting activities of a short gamma-ray burst (sGRB), such as extended and plateau emissions. We investigate fallback accretion with r-process heating by performing one-dimensional hydrodynamic simulations and developing a semi-analytical model. We show that the usual fallback rate dM/dt ∝ t
−5/3 is halted by the heating because pressure gradients accelerate ejecta beyond an escape velocity. The suppression is steeper than Chevalier’s power-law model through Bondi accretion within a turn-around radius. The characteristic halting timescale is ∼104–108 s for the GW170817-like r-process heating, which is longer than the typical timescale of the long-lasting emission of sGRBs. The halting timescale is sensitive to the uncertainty of the r-process. Future observations of fallback halting could constrain the r-process heating on the scale of a year.

Published: December 2021

Data from the Transiting Exoplanet Survey Satellite (TESS) have produced of the order of one million light curves at cadences of 120 s and especially 1800 s for every ∼27 day observing sector during its two-year nominal mission. These data constitute a treasure trove for the study of stellar variability and exoplanets. However, to fully utilize the data in such studies a proper removal of systematic-noise sources must be performed before any analysis. The TESS Data for Asteroseismology group is tasked with providing analysis-ready data for the TESS Asteroseismic Science Consortium, which covers the full spectrum of stellar variability types, including stellar oscillations and pulsations, spanning a wide range of variability timescales and amplitudes. We present here the two current implementations for co-trending of raw photometric light curves from TESS, which cover different regimes of variability to serve the entire seismic community. We find performance in terms of commonly used noise statistics meets expectations and is applicable to a wide range of intrinsic variability types. Further, we find that the correction of light curves from a full sector of data can be completed well within a few days, meaning that when running in steady state our routines are able to process one sector before data from the next arrives. Our pipeline is open-source and all processed data will be made available on the websites of the TESS Asteroseismic Science Operations Center and the Mikulski Archive for Space Telescopes.

Published: December 2021

BACKGROUND: The review examines the main stages of the formation of anthropometric monitoring of the physical development of children and adolescents in pediatric practice. Various factors that have a complex effect on the growth and physical development of the child’s body are shown.

AIM: The aim of research is to identify features of physical development in adolescents aged 12–14 years and make assessment and analysis. The importance of conducting modern research to determine the anthropometric indicators of the norm for children and adolescents living in different regions is indicated. The research was conducted in educational institutions.

METHODS: A total of 756 boys and girls aged 13–14 were examined. The study of the main trends in the formation of physical and sexual development of children and adolescents over the past decade can serve as a basis for the development of measures to preserve reproductive health.

RESULTS: Assessment of the physical development of children showed that 72-73% of children aged 13-14 years have a harmonious (normal) physical development. Among 14-year-olds, the deficit is relatively more common among girls, and the excess is the opposite among boys.

CONCLUSION: The progress of the external signs of puberty at the height of puberty was determined by the actual age (internal clock, i.e., the genetic program) and, in addition, and independently of this, the achieved body weight.

The species,E. wellsisp. nov., is described, illustrated, and com­pared with its congeners.Esola wellsisp. nov.differs from its known congeners in details of the armature of legs 1–4. It most closely resemblesE. bulbifera(Norman, 1911) in the armature formula of P1–P5 but differs from the latter in several respects, including the female antennule segmentation (7-segmented inE. bulbiferabut distinctly 6-segmented inE. wellsisp. nov.) and in the shape and size of the male P3ENP2 apophysis, among other characters. This is the second species of the genus known from the Caribbean and the second record ofEsolain the Northwestern Tropical Atlantic. The genus now contains eight species. A key to the known species of the genus is also included.

Objective

To determine the presence of axial symptoms in patients with psoriatic arthritis (PsA) and examine differences between those with or without a diagnosis of axial PsA (axPsA).

Methods

Patients with PsA at their Corevitas’ (formerly Corrona) Psoriatic Arthritis/Spondyloarthritis Registry enrollment visit were stratified into 4 mutually exclusive groups based on axial manifestations: physician-diagnosed axPsA only (Dx+Sx–), patient-reported elevated spine symptoms only (Dx–Sx+; defined as Bath Ankylosing Spondylitis Disease Activity Index ≥ 4 and spine pain visual analog scale ≥ 40), physician-diagnosed and patient-reported manifestations (Dx+Sx+), and no axial manifestations (Dx–Sx–). Patient characteristics, disease activity, and patient-reported outcomes (PROs) at enrollment in each axial manifestation group were compared with the Dx–Sx–group. Associations of patient characteristics with the odds of having axial manifestations were estimated using multinomial logistic regression (reference: Dx–Sx–).

Results

Of 3393 patients included, 226 (6.7%) had Dx+Sx–, 698 (20.6%) had Dx–Sx+, 165 (4.9%) had Dx+Sx+, and 2304 (67.9%) had Dx–Sx–. Patients with Dx–Sx+or Dx+Sx+were more frequently women and had a history of depression and fibromyalgia (FM) vs patients who had Dx–Sx–. Patients with Dx+Sx–or Dx+Sx+were more frequently HLA-B27 positive than those with Dx–Sx–. FM was significantly associated with increased odds of Dx+Sx–or Dx+Sx+. Disease activity and PROs were worse in patients with Dx–Sx+or Dx+Sx+than in those with Dx–Sx–.

Conclusion

Patients who had self-reported elevated spine symptoms, with or without physician-diagnosed axPsA, had worse quality of life and higher disease activity overall than patients without axial manifestations, suggesting an unmet need in this patient population.

Purpose:

To study the epidemiology, etiologies, and complications of playtime open globe injuries in children at the Assiut University Hospital, Egypt.

Methods:

This prospective cross-sectional study enrolled children with open globe injury who were admitted to Assiut University Hospital during a 6-month period (January to July 2016). All causes of trauma that occurred during playtime (at home, outside home, at the club, or at school) were recorded and analyzed.

Results:

Eighty-one children (age = 18 years and younger; mean ± standard deviation age = 8.35 ± 4.84 years) were admitted with open globe injury, and 32 of them (39.51%) sustained ocular trauma during playtime. The majority of children were boys (n = 23, 71.88%). The causes of trauma during playtime were: playing with sharp objects (n = 11; 34.38%), playing with a wooden stick (n = 7; 21.88%), falling on the ground (n = 5; 15.63%), trauma by a stone (n = 2; 6.25%), trauma during running (n = 1; 3.13%), playing with a plastic toy (n = 1; 3.13%), and unknown causes (n = 5; 15.63%). The sites of globe perforation were corneal (n = 23; 71.88%), corneoscleral (n = 8; 25%), and scleral (n = 1; 3.13%).

Conclusions:

Playtime trauma that causes open globe injury and visual disability is avoidable and constituted approximately half of the open globe injuries in this study population. Corneal involvement occurred in almost all open globe injuries. Parental supervision for children during playtime is crucial to injury prevention. Children should avoid playing with sharp, dangerous objects and desist from playing or running on unsafe ground.

It's undeniably true that fractional calculus has been the focus point for numerous researchers in recent couple of years. The writing of the Caputo-Fabrizio fractional operator has been on many demonstrating and real-life issues. The main objective of our article is to improve integral inequalities of Hermite-Hadamard and Pachpatte type incorporating the concept of preinvexity with the Caputo-Fabrizio fractional integral operator. To further enhance the recently presented notion, we establish a new fractional equality for differentiable preinvex functions. Then employing this as an auxiliary result, some refinements of the Hermite-Hadamard type inequality are presented. Also, some applications to special means of our main findings are presented.

Purpose: The use of mobile devices among medical students and residents to access online material in real-time has become more prevalent. Most literature focused on the technical/functional aspects of mobile use. This study, on the other hands, explored students, doctors and patients’ preferences and reasons towards the use of mobile devices in clinical settings underpinned by the Technology Acceptance Model 2 (TAM 2).Methods: This research employs an exploratory research design using survey and semi-structured interviews. An online survey was administered to clinical year medical students, followed by semi-structured interviews with the doctors and patients. Questions for the online survey and semi-structured interviews were derived from previous literature and was then reviewed by authors and an expert panel. A convenience sampling was used to invite voluntary participants.Results: Survey findings showed that most medical students used their devices to find drug information and practice guidelines. The majority of the students accessed UpToDate followed by Google to access medical resources. Key barriers that students often encountered during the use of mobile devices were internet connectivity in the clinical settings, reliability of the information, and technical issues. Thematic analysis of the interviews revealed four themes: general usage by students, receptivity of the use of mobile devices by students, features in selecting resources for mobile learning, and limitation in the current use of mobile devices for learning.Conclusion: The findings from this study assist in recommending suitable material using mobile devices to enhance learning in the clinical environment and expand the TAM 2.

Since coronavirus disease 2019 was declared a global pandemic by the World Health Organization, it has become a challenging situation to continue medical education, including in Indonesia. The situation prohibited face-to-face (direct) educational activities in clinical settings, therefore also postponing examinations involving especially procedural skills. Adaptations were urgently needed to maintain the delivery of high-stake examinations to sustain the number of ophthalmology graduates and the continuation of eye health service. Objective structured clinical examination (OSCE) has been one of our widely used method to assess clinical competencies for ophthalmology residents, and is the one method that involves gatherings, close contact of examiners, examinees and patients, therefore the most difficult to adjust. Pandemic challenges brought technical changes in our delivering the OSCE to online, maximizing digital platforms of meetings, while still concerned to guarding the safety of candidates, patients and staffs. OSCE scenarios were also made as timely efficient as possible by changing continuous station models to a cascade one. The purpose of this article is to document our experience in conducting a feasible and reproducible OSCE in this pandemic era filled with limitations.

This study explores local community attitudes toward ecotourism as a form of sustainable tourism in the Zasavica Special Nature Reserve in Serbia using the Sustainable Tourism Attitude Scale (SUS-TAS). Residents of the Zasavica Special Nature Reserve acknowledge the sociocultural and economic benefits of ecotourism development while recognizing the negative impacts of development on the natural environment. Low awareness of non-charismatic species among residents contrasts with strong awareness of them among large communities of scientists and naturalists in Serbia. This study shows the importance of local community support for ecotourism and conservation development. Moreover, the study revealed that the SUS-TAS scale can be successfully applied in ecotourism research.

Authors: Prencipe Matteo Pio , Maleki Vishkaei Behzad , De Giovanni Pietro
Published: December 2021

This chapter identifies the existing challenges in the winery industry and proposes to analyze their resolution by the adoption of blockchain technology. Blockchain allows the traceability of the whole process linked to wine production, from the cultivation of the grapes to the distribution of the bottles. Blockchain allows winery firms to unlock the potential value existing in some processes, especially when they create a competitive advantage. The chapter investigates these concepts within the case of Cantina Volpone, which has been the first case in Italy to adopt blockchain technology in the winery industry. This chapter studies the implementation path for blockchain technology in the winery industry and highlights the operational and financial challenges emerging from its adoption.
