Published: March 2022

Background: Bovine Leptospirosis is one of the leading causes of abortion, infertility, stillbirths and sudden drop in milk production to complete agalactia in cattle and buffaloes. An outbreak in water buffaloes with the history of sudden appearance of bloody/pinkish milk from all four quarters and decrease in milk production to complete agalactia was investigated in village Baghot, Mahendergarh, Haryana, India. Methods: A total of fifty eight (n=58) biological samples (milk=38, blood=11 and urine =9) samples) from 17 buffaloes were collected from Baghot and its neighbouring villages of district Mahendergarh, Haryana, India. All collected samples were processed for molecular diagnosis using pathogenic Leptospira specific TaqMan probe based real-time PCR and nucleotide sequencing. Result: The pathogenic Leptospira spp. was detected in real time PCR from milk samples of 6 animals (35.2%) out of 17 buffaloes. None of the blood and urine sample was found positive for pathogenic leptosipra spp. PCR amplified product were further sequenced and confirmed pathogenic Leptospira spp. The affected animals in the village were treated with parenteral administration of Streptopenicillin, Tranexamic acid and Ascorbic acid for 3-5 days, in recommended doses. Treated animals responded positively to the therapeutic regimen. Furthermore, animal owners and veterinary staff were instructed to take protective measures to ensure no further spread to animals and humans.

The flora of the island of Zlarin was studied in 2019 and mapped using the Central European grid (MTB fields), the area studied consisting of nine MTB 1/64 fields. Altogether 576 vascular plant taxa (532 species and 44 subspecies) were identified, out of which there were 126 newly recorded, 450 previously recorded and confirmed, while 153 taxa from previous authors were not confirmed. In total, 730 taxa are currently recorded on the island of Zlarin. Among these, 580 taxa are indigenous, 147 cultivated and 23 listed as invasive in Croatia. Cultivated and adventitious plants were not included in the analysis of families and life forms. The largest number of taxa was attributed to the families Compositae (13.89%), Fabaceae (12.01%) and Poaceae (10.98%). Along with the domination of therophytes, the results of the phytogeographical analysis show a dominance of the Mediterranean floral element, indicating the character of the flora. Altogether 13 endemic, 44 endangered and 42 strictly protected indigenous species and subspecies are currently recorded on the island. The highest plant richness was observed in fields with higher habitat diversity and in fields with olive groves maintained by mowing. Moderate human impact and habitat diversity are crucial for the increase in floristic diversity on small islands and are much more important than the size of the island itself.

Derechos de la Naturaleza (en relación con el derecho a la naturaleza)
Authors: Tassin Wallace Catalina
Published: March 2022

Este trabajo tiene por intención analizar dos formas de proteger a la naturaleza. Por un lado, lo que se denominará desde ahora en más «derecho a la naturaleza» y por el otro «derechos de la Naturaleza». Desde el primer modelo se salvaguarda a la naturaleza atribuyéndole a otra entidad, específicamente al ser humano, determinados derechos; desde el segundo se reconoce a la Naturaleza el carácter de sujeto de derecho. Ambos posicionamientos suponen argumentaciones y discusiones diferentes, que operan en vistas de cierto tipo de protección, fines y posturas. Teniendo en cuenta lo anterior, en este trabajo se busca corregir la siguiente afirmación: la figura jurídica de la naturaleza como titular de derechos es una cuestión no resuelta. Se trata de un asunto totalmente definido, sólo depende de si se reconoce a la naturaleza como activa (Naturaleza) o se la entiende como un objeto receptivo de acción (naturaleza).
La formación del jurista a mediados del siglo XXI. Más preguntas que respuestas
Authors: Zornoza Pérez Juan
Published: March 2022

El presente trabajo, sobre la base de la experiencia, plantea una perspectiva crítica en torno a los planes universitarios de los estudios jurídicos. Estas se concretan en una excesiva preponderancia de las universidades al fijar sus contenidos con escasa participación de los diversos colegios de las distintas profesiones jurídicas, así como de las administraciones públicas. Asimismo, se ha producido un crecimiento desequilibrado de las plantillas de profesorado y una progresión de los dobles grados que ha resultado insatisfactoria. Finalmente, plantea algunas cuestiones como la orientación de la formación de los másteres, la influencia de las nuevas tecnologías y la internacionalización del Derecho, concluyendo en algunas consideraciones metodológicas sobre la enseñanza del Derecho.

Introduction: Clostridioides difficile is the main cause of healthcare-associated diarrhea in Europe and North America. The aim of this study was to characterize the epidemiology and clinical burden of Clostridioides difficile infection among hospitalized patients in Portugal.Material and Methods: Retrospective study conducted in six public hospital centers in Portugal. All primary Clostridioides difficile infection episodes and related recurrences occurring in 2017, as well as episodes developing two to eight weeks after the last episode diagnosed in that year, were documented. The National Reference Laboratory (National Institute of Health Dr. Ricardo Jorge) provided national surveillance data on Clostridioides difficile infection.Results: A total of 385 inpatients with at least one primary episode diagnosed in 2017 were included. Most patients were aged over 70 years-old (73.2%). The included patients developed 451 episodes during the observation period. Approximately 44% of primary episodes were community-associated. Most episodes (94.9%) occurred in patients with one or more risk factors, with recent antibiotic exposure being particularly common (86.0%). All-cause in-hospital mortality was 19.5%, being significantly higher in patients aged over 65 years-old versus those aged 18 to 64 years-old (22.4% vs 7.8%, respectively). Over 50 different ribotypes were observed among 206 Clostridioides difficile strains received by the National Reference Laboratory.Conclusion: In Portugal, hospitalized patients with Clostridioides difficile infection are mostly older patients presenting risk factors for the development of this infection, particularly recent antibiotic exposure. Mortality is disproportionately high among the older population. Community-associated Clostridioides difficile infection is common among inpatients with this infection.

Tannic acid modified iron oxide nanoparticles and its application in protein adsorption: isotherm, kinetic, and thermodynamic study
Authors: Kristianto Hans , Alexander Joshua , Prasetyo Susiana , Sugih Asaf K
Published: April 2022

Iron oxide nanoparticles, such as Fe3O4, are commonly used in various applications, such as drug delivery, magnetic fluid, water purification, and enzyme immobilization. These applications require protein to be adsorbed on the surface of iron oxide nanoparticles. However direct utilization of iron oxide nanoparticles has several drawbacks, thus modification of iron oxide nanoparticles is usually done. In this study, we reported surface modification of Fe3O4 using tannic acid to adsorb bovine serum albumin (BSA). The effect of modification and the BSA adsorption on the Fe3O4 was characterized using Fourier Transform Infrared Spectroscopy, X-ray Diffraction, Scanning Electron Microscopy, and Transmission Electron Microscopy. Furthermore the adsorption performance of modified and unmodified Fe3O4 was investigated at various initial pH, BSA concentration, and adsorption temperature. Several kinetic and isotherm adsorption models were used to describe the adsorption in this study. It was found that highest BSA adsorption was obtained at pH 4.8, near BSA’s isoelectric point. The adsorption kinetics followed the pseudo 2nd order model and reached equilibrium after 210 min adsorption. Based on Langmuir monolayer adsorption capacity, it was found that tannic acid modified Fe3O4 had 5 times higher adsorption capacity (222 mg/g), compared to unmodified Fe3O4 (46 mg/g). Furthermore, from the thermodynamic study, it was suggested that the BSA adsorption was endothermic, spontaneous, and random in nature.

The coastal is frequently impacted by marine litter that damages marine wildlife and causes economic loss to fishing and maritime industries. In this study, we described the quantity of marine litter in the inner and outer of Ambon Bay. The Sampling was carried out in September 2017. The beach litter sampling was handled by the line transect method combined with the quadrant method in 8 sites; the observation of floating litter was conducted manually with boat sampling and visual observation in a seven-line trajectory. About 2359 items of coastal litter were found in seven sites in Ambon Bay with a mean density of 18.87 items.m -2. These beach litter belonging to five categories were counted (plastic, glass, metal, cloth, paper). The highest abundance of beach litter was found in the inner Ambon Bay with a mean density of 68.74 items per m2. Plastic was the most abundant beach litter observed. Based on Clean Coast Index (CCI) evaluation, all coastal sites in Ambon Bay were identified as Very Dirty, that is most of the coastal is covered with litter. The highest floating litter was found near the market. The abundance and distribution of litter through Ambon Bay seem to be influenced by the local human population, anthropogenic activities, and seawater circulation in inner and outer Ambon Bay.
Temperature control system on greenhouse effect gaplek dryer
Authors: Aprillia Bandiyah Sri , Pramudita Brahmantya Aji , Megantoro Prisma
Published: March 2022

Gaplek is a processed product of cassava that requires a drying process to remove the water content in cassava. Solar thermal energy can be used for the drying process of gaplek by using a greenhouse effect drying system. However, the greenhouse effect drying system using solar thermal energy is very dependent on weather conditions and temperature that is difficult to control. Therefore, a temperature control system is proposed in this study by utilizing Pulse Width Modulation (PWM) to control the exhaust fan speed. Thus, the temperature can be maintained according to the drying standard of processed cassava products. In this study, a temperature control system has been successfully created that is able to maintain the temperature in the drying room according to the drying standard, namely at a temperature of 50℃ to 60℃ when tested in three different locations, namely, Sukamaju Village, Kaligunting Village, and Sumberejo Village which have shown optimal drying temperature.
Reconciling the Cosmological Constant with the Energy Density of Quantum Field Theories of the Zeropoint
Authors: Cornwall Remi
Published: April 2022

This paper results from our investigation into novel means of electromagnetic propulsion. It requires the basis of our claims to be put on a sound theoretical footing regarding the purported momentum exchange with the electromagnetic field. One of these concerns is the huge discrepancy between the energy density of the Zeropoint and its purported manifestation as the Cosmological Constant. Here we state that it is manifestly wrong to introduce the zeropoint at zero order into the stress-energy tensor, because it is something which describes zero particle count. As a fluctuation, it belongs in a higher order Taylor expansion in frequency of the stress-energy tensor. Furthermore in the 3rd order in the Einstein constant our procedure is some 9 orders of magnitude too small. We make up this difference by suggesting that vacuum energy is much higher still and that more degrees of freedom exist in physics beyond the Standard Model or that there is interaction energy between the modes.

Published: March 2022

Road vehicles are a large contributor to Nitrogen Oxides (NOx) pollution. The routine road-side monitoring stations, however, may underrepresent the severity of personal exposure in urban areas, because long-term average readings cannot capture the effects of momentary, high peaks of air pollution. While numerical modelling tools historically have been used to propose an improved distribution of monitoring stations, ultra-high resolution Computational Fluid Dynamics models can further assist the relevant stakeholders in understanding the important details of pollutant dispersion and exposure at local level. This study deploys a 10 cm-resolution CFD model to evaluate actual high peaks of personal exposure to NOx from traffic, by tracking the gases emitted from the tailpipe of moving vehicles being dispersed towards the roadside. The investigation shows that a set of four Euro 5-rated diesel vehicles travelling at constant speed may generate momentary road-side concentrations of NOx as high as 1.25 mg/m3, with 25% expected increase for doubling the number of vehicles and approximately 50% reduction when considering Euro 6-rated vehicles. The paper demonstrates how the numerical tool can be used to identify the impact of measures to reduce personal exposure, such as protective urban furniture, as traffic patterns and environmental conditions change.

The article aims at comparison the impact of traditional and inclusive educational processes on the quality of life of children with ASD. All countries observe a tendency to increase the number of children with special educational needs. A special category is children with autism spectrum disorders (ASD). Such children are characterized by a pronounced lack of social interaction and ability to communicate. Therefore, it is important to investigate whether the processes of adaptation of such children in the conditions of inclusion and traditional education in special institutions will be equally effective. Such research remains relevant due to the lack of clear recommendations on how to organize the learning process and content saturation of individual training programs, as well as physical education tools that are effective in treatment and correction to improve the quality of life of program participants. As a result, all the features of the pedagogical process and socio-pedagogical support of children with special needs in schools were studied.

Cognitive radio technology is a promising way to improve bandwidth efficiency. Frequency which is not used in any aspect will be utilized by using some of the most powerful resources in this cognitive radio. One of the main advantages of cognitive radio signal is to detect the different channels which are there in the spectrum and it can modify the frequencies which is utilized frequently. It allows the licensed users to gain the licensed bandwidth under the condition to protect the licensed users from harmful interference i.e., from secondary users. In this paper, we would like to implement cognitive radio using the beamforming technique, by using power allocation as a strategy for the unlicensed transmitter which is purely form on the result of sensing. It is on the state of the primary user in a various cognitive radio network whereas the unlicensed transmitter gives a single antenna and it modify its power transmission. For the cognitive radio setup, we have used normalized adaptive learning algorithms. This application would be very useful in medical telemetry applications. Nowadays wireless communication plays a vital role in healthcare applications for that we have to build a separate base. It reduces the effort of the building of separate infrastructure for medical telemetry applications.

Compositional Reservoir Simulation: A Review
Authors: Young Larry C.
Published: March 2022

Compositional reservoir models have many uses, including petroleum reservoir simulation, the simulation of flow and remediation of nonaqueous petroleum liquids, and the study of various carbon-capture technologies. The present work describes these models in a general way but concentrates on isothermal compositional models based on an equation of state (EOS). These models are used to study petroleum reservoirs containing gas condensate or volatile oil fluids and various gas injection processes like CO2 injection. The technology is documented from the earliest rudimentary models which first appeared more than 50 years ago to more recent work. The system of differential-algebraic equations is described along with the physical nature of the parameters. Model formulations are compared with respect to choices of variables and other computational features. Descriptions of efficient and reliable computational procedures are given. In addition to basic algorithms, we detail important side issues of (1) testing for phase appearance, (2) temporal stability, (3) material balance, and (4) other efforts to speed up the calculations and/or reduce the calculation requirements. Information in the literature is supplemented with some work which has not been presented previously. Correct rendering of the physics and chemistry is emphasized which is often intertwined with the numerics. Although many improvements have been made, the work is not finished. We conclude with a discussion of areas needing additional work.

ObjectiveTo explore the clinical application value of ultrasound elastography (UE) technology in the evaluation of the efficacy of neoadjuvant chemotherapy (NAC) at different time-points in patients with locally advanced breast cancer.MethodsTwo group patients were performed conventional ultrasound and elastography examination before NAC (pre-NAC),after the second (post-2nd-NAC), and the fourth cycles of NAC(post-4th-NAC),including 40 cases of 40 breast cancer patients (age range, 25-72 years) in Strain Elastography (SE) group and 21 cases of 20 breast cancer patients (age range,31-67 years) in shear-wave elastography (SWE) group. Changes in elastographic parameters (elasticity grading and strain ratio in SE group, the maximum elastic value and the average elastic value in SWE group) related to tissue biomechanical properties were then determined and compared to clinical and pathologic tumor response after mastectomy. Receiver operating characteristic (ROC) curve analysis was performed to examine parameters at SE and SWE to predict pathologic response. ResultsThe difference of the SE scores between the effective and the ineffective group were statistically significant, no matter after the second or fourth cycles of NAC(P = 0.003 and P = 0.002).The efficacy of NAC can be evaluated by SE semi-quantitative method（no matter with normal breast tissue or adipose tissue as reference）(with normal breast tissue as reference: area under the receiver operating characteristic curve(AUC): 0.763 (post-2nd-NAC),0.836 (post-4th-NAC) ; sensitivity:66.7% (post-2nd-NAC) , 83.3% (post-4th-NAC); and specificity:87.5% (post-2nd-NAC) , 87.5% (post-4th-NAC)；with adipose tissue as reference area under the receiver operating characteristic curve: 0.733 (post-2nd-NAC) ,0.775 (post-4th-NAC); sensitivity: 66.7% (post-2nd-NAC) ,87.5% (post-4th-NAC); and specificity: 75% (post-2nd-NAC) , 68.7% (post-4th-NAC)) and SWE quantitative parameters(taking Emean as measurement parameter: area under the receiver operating characteristic curve: 0.929 (post-2nd-NAC) ,0.929 (post-4th-NAC); sensitivity:85.7% (post-2nd-NAC), 78.6% (post-4th-NAC); and specificity100% (post-2nd-NAC), 100% (post-4th-NAC);taking Emax as measurement parameter: area under the receiver operating characteristic curve: 0.898 (post-2nd-NAC) , 0.908 (post-4th-NAC); sensitivity: 85.7% (post-2nd-NAC) , 71.4% (post-4th-NAC); and specificity100% (post-2nd-NAC), 100% (post-4th-NAC)) after the second and fourth cycles of NAC. There was no significant statistically difference between SE semi-quantitative methods and SWE quantitative parameters in the evaluation of the efficacy of NAC (P =0.082 post-2nd-NAC and 0.324 (post-4th-NAC)). ConclusionBoth SE and SWE can be potentially used as an early predictor of tumor therapy response in locally advanced breast cancer patients, and there was no significant difference in their assessment effectiveness
Effect of PbO Incorporation with Different Particle Sizes on Structural and Mechanical Properties of Polystyrene

Published: April 2022

Two different sizes of PbO nanoparticles, notably PbO(A) and PbO(B) with sizes of 78 nm and 54 nm, respectively are produced using a high-speed planetary ball milling machine under specific operating parameters. Following, the novel nanocomposite PS/PbO is synthesized using compression molding by embedding 10, 15, 25, and 35 wt% of PbO(Bulk), PbO(A) and PbO(B) into PS separately. The composite is further characterized by Fourier transform infrared spectrophotometer (FTIR), scanning electron microscope (SEM), energy-dispersive X-ray spectroscopy (EDS) and laser-induced breakdown spectroscopy (LIBS). FTIR results confirm the presence of PbO, and indicate a physical adsorption of the nanoparticle onto the PS matrix surface. SEM, EDS and LIBS analyses reveal a more efficient diffusion of PbO in the PS matrix with the decrease of the nanoparticle size. On the other hand, Tensile and Vickers microhardness tests are performed to investigate the composite's mechanical properties. The stiffness is, indeed, enhanced with increasing weight fraction, as well as with decreasing particle size of PbO. Whereas, the strength of the composite is optimized with 15wt% of PbO. Microhardness test reveals an ISE behavior of the composite, and an increase in H v values with PbO loads up to 15 wt%. Accordingly, by adjusting the filler particle size and concentration, the mechanical properties of the composite are evidently enhanced, increasing their use in a variety of applications such as coating, insulation and radiation shield.

Background: Quantitative assessment of the risk of local transmission from imported dengue cases makes a great challenge in China. The purpose of this study is to observe the risk of mosquito-borne transmission in Xiamen City through ecological and insecticide resistance monitoring. Quantitative evaluation of mosquito insecticide resistance, community population and the number of imported cases affecting the transmission of dengue fever in Xiamen was carried out based on transmission dynamics model to investigate the correlation between key risk factors and DF transmission.Methods: Based on the epidemiological characteristics of DF in Xiamen City, a transmission dynamics model was built to simulate the secondary cases caused by imported cases to evaluate the transmission risk of DF, and to explore the influence of mosquito insecticide resistance, community population and imported cases on the epidemic situation of DF in Xiamen City.Results: For the transmission model of DF, when the community population was between 10,000 and 25,000, the number of imported DF cases and the mortality rate of mosquitoes were associated with the spread of indigenous DF cases, however, the birth rate of mosquitoes could not gain more effect on the spread of local DF transmission.Conclusions: Through the quantitative evaluation of the model, this study determined that the resistance of mosquito has an important influence on the local transmission of dengue fever caused by imported cases in Xiamen, and the Breteau index can also affect the local transmission of the disease.

In this study, rice husk and jatropha shell were employed as precursors for the production of activated carbon by thermal and chemical activation process using phosphoric acid (H3PO4). The thermally activated carbon derived rice husk (RH) and jatropha shell (JS) and phosphoric acid activated derived rice husk (RH-Ac) and jatropha shell (JS-Ac) were characterized using BET, XRD, FTIR, Raman spectroscopy, SEM and XPS analysis. It showed that the cavities developed on the surfaces of RH-Ac and JS-Ac were be more high than those RH and JS. The BET surface area of RH, JS, RH-Ac and JS-Ac were 694.3 m2/g, 723.1 m2/g, 1261.3 m2/g and 1327.7 m2/g, respectively. The XPS analysis revealed that RH and JS exhibited the relative lower contents of carbonyl and phenol carbon than RH-Ac and JC-Ac. The as-prepared RH-Ac and JC-Ac were employed for the adsorption of Cu2+ and Fe2+ due to it better physicochemical properties. The most important influencing factors the adsorption of these metal ions such as pH, contact time, initial concentration were systematically studied. Experimental results were well analyzed by Langmuir model with the maximum adsorption ability of Cu2+ (22.773 mg/g), Fe2+ (25.431 mg/g) onto RH-Ac and Cu2+ (32.458 mg/g) and Fe2+ (56.179 mg/g) onto JS-Ac, which showed to be high in comparison to the similar activated carbon available obtained by other researchers. The pseudo 2nd order model showed that adsorption kinetic of Fe2+ and Cu2+ ions onto the JS-AC and RH-Ac has domination towards chemisorption. Moreover, thermodynamic parameters suggested that RS-Ac and JS-Ac for Cu (II) and Fe (II) adsorption phenomenon was endothermic and spontaneous. The high availability, facile production along with high performance of RH-Ac and JS-Ac make it an economically adsorbent for Fe (II) and Cu (II) adsorption.

Introduction: Determining which patients will experience recurrence of atrial fibrillation (AF) is crucial for treatment modification. Aim: This study aimed to investigate the value of left atrial kinetic energy (LAKE) in atrial fibrillation recurrenceMethods: A total of 120 consecutive patients who achieved sinus rhythm with electrical direct current cardioversion and met the inclusion criteria were included in the study. TTE and LAKE values were calculated on the first day after cardioversion. Rhythm control was performed with 12-lead electrocardiography in the first month follow-up. LAKE values calculated using TTE was compared between two groups of patients – those who remained in sinus rhythm and those who developed AF.Results: While 81 (67.5%) patients were in sinus rhythm at one month, AF recurrence was detected in 39 (32.5%) patients. In the AF group, while AF duration, cardioversion energy, number of diabetic patients, left atrial (LA) diameter, LA pre A volume, LA minimum volume, and pulmonary artery pressure values were found to be significantly higher than those in the SR group, mitral A velocity and LAKE values were significantly lower. In multivariate regression analysis, AF duration (OR: 1.55 [CI: 95%; 1.23–1.95]; p < 0.001), LA diameter (OR: 1.36 [CI: 95%; 1.11–1.66]; p = 0.003) and LAKE (OR: 0.96 [CI: 95%: 0.94–0.99]; p = 0.008) were determined to be independent predictors of AF recurrence at one month.Conclusions: LA diameter, AF duration, and LAKE were found to be significant predictors of AF recurrence after cardioversion.
