Sudden death due to atypical Fournier’s gangrene following Methicillin-resistant Staphylococcus aureus (MRSA) infection: a forensic case
Authors:   Stefano Tambuzzi#, Guendalina Gentile#, Enrico Muccino, Riccardo Zoja
Published: March 2022

Fournier’s gangrene is a rare and progressive necrotizing infection affecting the perineal, periureteral, perianal, or genital area associated with high mortality rates. A 34-year-old obese man went to the emergency room, complaining of painful perianal and perineal swelling. He was hospitalized and the computed tomography (CT) scan revealed large bilateral anorectal abscesses, anteriorly extended to the base of the scrotum and on the right to the ischiorectal fossa. A diagnosis of Fournier’s gangrene was made and broad-spectrum antibiotic therapy was started. After the abscesses drainage, microbiological examinations were performed. However, the clinical conditions furtherly worsened and the patient was moved to the medical intensive care unit. The microbiological analyses tested positive for Methicillin-resistant Staphylococcus aureus (MRSA) and the antibiotic therapy was modified accordingly. Despite the treatment, the hypotension worsened and the patient died from sepsis and multi-organ failure. Upon autopsy, we observed an external macroscopic picture devoid of the typical destructive lesions that usually characterize Fournier’s gangrene. Therefore, we found ourselves faced with an atypical case which, in the absence of the clinical data, would certainly have been difficult to diagnose based on the autopsy findings only. The presented case is deemed of interest for both clinicians and medical examiners since it is about a highly aggressive and fatal Fournier’s gangrene in the absence of destructive external manifestations. Moreover, this atypical case of Fournier’s gangrene was sustained by an emerging and highly aggressive microbial agent, eventually evolved into sudden death.

The research allowed one to prove the seasonal organization of pasture economy using the distant pasture. The studies were carried out in 2018-2021 in the semi-desert zone of Western Kazakhstan. The aim of the research is to study and select the best ways to use pastures for organizing measures for their rational management. The soil of the areas of unsystematic and seasonal grazing is light chestnut medium loamy. Driving pastures are located in the sands zone. In the summer period, an increase in the number and occurrence of valuable pasture plants Kochia prostrata, Agropyron desertorum, Festuca valesiaca, Leymus ramosus, Koeleria cristata was noted on seasonal pastures. On the distant site of sandy pastures, 23 plant species of different economic and botanical groups have been determined, and due to the natural conditions of sands in the phytocenosis, the occurrence of valuable plants in the forage ratio is high. By the middle of summer, in the area of seasonal and distant pastures, despite the loss of forbs from the vegetation composition and drying of cereals, the yield of green phytomass was 0.81-1.03 t/ha, which is 0.43-0.65 t/ha. In this work, it was concluded that to improve the efficiency of pasture resource management, it is important to use seasonal pastures with the inclusion of a distant site in pasture rotation, which is the scientific novelty of the research.

The results of a comprehensive study of the formation of the yield of six different early maturity potato varieties, the originator of which is AGRICO U.A. and LANIMANNEN SW SEED BV: early ripening Impala (control), mid-early ones - Arizona, Excellens, Evolution, mid-ripening-Fontane, Aluet are presented. The studies were carried out in 2018-2020. on sod-podzolic light loamy well-cultivated soil in the crop rotation of Agroforward LLC (Agrico-Eurasia) in the Shatura district of the Moscow region. Potatoes were cultivated using Dutch technology with a row spacing of 75 cm.

It was revealed that the studied varieties differed among themselves in the intensity and direction of the production process, the coefficient of the economic efficiency of photosynthesis (Khoz.). These indicators were higher in the Impala and Evolution varieties. Thus, the average daily gain in dry weight of a whole plant during the growing season was 2.10 and 2.25 g / plant, respectively, tubers 2.51 and 2.41 g / plant; khoz 0.73 and 0.70. In other varieties, these indicators were 4.3 - 23.5% lower, especially in the Aluet variety. The Impala and Evolution cultivars were distinguished by a higher productivity of the leaf photosynthetic potential. They received 21.1 and 20.3 kg of tubers per 1,000 units of photosynthetic potential, which led to the formation of yield, on average over 3 years, 39.8 and 37.9 t / ha with the plan of 40 t / ha. Other varieties reduced yields in comparison with the control by 13.7 -36.6%, which limits their recommendations for cultivation in production.

Published: March 2022

Based on the calculation of the selection and genetic parameters of the main indicators of sperm production of Holstein bulls in different age periods, an assessment of their own productivity under the influence of various factors was carried out. The factors "year" and "year of birth" have a significant effect on the volume of ejaculate (n=2.4-4.0%***), the total number of spermatozoa in the ejaculate (?=3.7-2.8%***), the concentration of spermatozoa (?=1.4-2.4%***). The factor "age of the bull" also significantly affects the quantitative indicators of sperm production. There are significant differences in the volume of ejaculate (P?0.001, R2=0.93), the total number of spermatozoa (P?0.001, R2=0.85). The concentration of spermatozoa in 1 ml decreases with age (R2=0.63), at the age of 1-2 years, the indicator value is higher than in all other age periods up to 12 years (P?0.001). The volume of ejaculate and the concentration of spermatozoa had relatively high heritability coefficients – 0.51 and 0.65, respectively. The genetic and phenotypic correlations between the volume and the number of spermatozoa of 0.68 and 0.52 are determined by the average relationship. In all age periods, the relationship between the indicators of the own productivity of producing bulls was mainly linear. A significantly high correlation between the volume and the number of sperms in the ejaculate was at the level of +0.59(P?0.001)...+0.66 (P?0.001); between the number and concentration of sperms at the level of +0.31(P?0.001)...+0.49 (P?0.001) in all age periods.

Authors: Ismayilova Hijran
Published: March 2022

The main purpose of the research is to increase the output and improve the quality of condensed sunflower seeds based on the structural synthesis of subclasses of cleaning machines, and is the detection of regularities of their activity in the seed-cleaning unit, during the implementation of new sequences in the process of cleaning the sunflower seeds. The annual production of sunflower seeds in Azerbaijan, according to statistics for the last decade, is 20,000 tons. The production of this volume is mainly carried out on small farms, and the size of the fields that they divide under the sunflower is 1.5 to 3.5ha. At the same time, these fields are distributed almost to all economic regions of the country. Seeds are mainly imported to Azerbaijan from the Krasnodar region of the Russian Federation and Ukraine. Seeds are spread without local adaptation and any seed cleaning and sorting resulted in a significant reduction in the efficiency of agricultural production technology, greater waste of sowing material, and less harvesting. Therefore, the technology of seed production of sunflower seeds, both locally produced and imported, is considered a complex functional system that has a comprehensive impact on their quality, and the application of this system is essential in the production of sees in the different zones of the country. The development of such a functional system, adapted to the geography of sunflower seed production in the country, with low productivity and low material capacity, has been relevant to the economic situation of farmers.

Published: March 2022

Artificial intelligence has become the mainstream technology. Automatic vacuum clean- ers or robot vacuums change the field of vacuum cleaners with an involvement of an au- tomation, which is a technology that makes people’s daily life easier and more economical. Robot vacuums were invented by the Massachusetts Institute of Technology in 1990. To- day, robot vacuums are successful and have many users all around the world. More than 2.5 million families live in 60 countries use them. However, a question that is still being asked about robot vacuum is the efficiency of room coverage and the ability to remem- ber the redundant areas that have already been cleaned. The answers to these questions are unclear, as manufacturers do not reveal the algorithms that are learned by robots, or sometimes they just partially did, due to business reasons. This study was proposed in response to the above questions by using our mobile application for tracking and recording actual geolocations of the robot walking across various points of the room by extracting the real geolocation data from satellites consisting of a latitude and a longitude under multiple different room conditions. Once the robot has cleaned throughout the room, the applica- tion reported all areas that the robot has cleaned for analysis purpose. We presented the actual route map, the coverage area map, and the duplicate area map of the robot that potentially led the further understanding of robot vacuum’s effectiveness.
Contribution Ultra Violet Radiation On Degradation Of Biodegradable Base Oil
Authors: Ulfiati Ratu
Published: March 2022

Increasing environmental awareness led to the development of environmentally harmless lubricants made by biodegradable materials. Biodegradable lubricants are suitable for various kinds of application, one of the promising usages is for railways. Oils or greases are applied for railways or points to keep sufficient friction coefficient or to avoid wear damage. These lubricants are “once-through” lubricants, and never recovered but defused into the earth’s surface. The oxidation of lubricants on the railways will take place because of the sunlight effect. The solar radiation at the top of earth’s atmosphere contains a significant amount of UV radiation of shorter wavelength, and therefore higher energy. This study shows that the UV-B radiation can deteriorate rapeseed oil immediately. It is showed by the results of peroxide value, total acid number and molecular weight distribution are increased with oxidation time.
The Re-Analysis Of The Mature Western Area Of Indonesia Basins For Finding Additional Oil And Gas Resources

Published: March 2022

The oil and gas exploration activities in the last two decades in the mature sedimentary basins in the western area of Indonesia can be said has been in the stagnation phase. The activities are still limited in the effort of discovering shallow structures as the exploration targets which are of Miocene age and not older than Early Miocene. On the other hand, the oil and gas exploration on hydrocarbon plays, as well as new Paleogene sediments or others, has not been done intensively. Some problems which cause difficulty in finding new resources are such as lack of innovation in the exploration activities, and this is because the exploration operators are reluctant to bear the failure risk in the development of exploration activities that they do; which leads the exploration program carried out mainly focused only on the target or objective reservoir that is known. The effort of finding oil and gas resources in the future on the mature basins can be done by reanalyzing and revisit the evaluation on how the historical development of a sedimentary basin, that includes the development process and the tectonic sedimentation during the Tertiary era in relation to the formation of hydrocarbons. The reanalysis should be supported with the latest subsurface data, up-to-date geosciences concepts and sophisticated software and hardware which are able to perform the analysis of petroleum system in order to find new hydrocarbon-play as a new exploration target in the future. Various proposed activities in the re- valuation of the Tertiary sedimentary basins in Indonesia are the analysis of the Paleogene graben system of the back-arc basins of Sumatra and Java, the analysis of Miocene-Pliocene lowstand sediment, and the analysis of Miocene carbonate sediments, which have not been evaluated intensely so far.
Spectral Decomposition Made Simple

Published: March 2022

Spectral decomposition enables the resolution of seismic data to be improved significantly yielding a new possibility to map thin layers such channel sands and any other stratigraphic features. It has also been used in reservoir characterization. There are three methods for implementing spectral decomposition i.e., The Short Time Fourier Transform, the Continuous Wavelet Transform and the Matching Pursuit Decomposition. Among three of them, the Matching Pursuit Decomposition seems to be the most sophisticated one. It gives the best resolution among them. A simple and logical approach for explaining the spectral decomposition methods together with real data examples are presented in this paper by avoiding complex mathematical formulation.
Establishment Of More Reliable Equations For Estimation Of Coalbed Methane Proximate Analysis Data
Authors: Widarsono Bambang , Sartadiredja Kosasih , Widjayanto Bambang A
Published: March 2022

Coal bed methane (CBM) data such as ash contents, moisture contents, volatile matters, and fixed carbon – commonly obtained from log analysis - are direct input to calculation of gas accumulation in CBM reservoirs. However, recent studies on some coal samples taken from Rambutan field CBM pilot project have shown that the commonly used log analysis equations are simply inapplicable for the field’s coal samples. Calculation results tend to give far different magnitudes when compared to laboratory results. After a series of re-evaluations and re-measurements on the laboratory results it was convinced that the problem does not lie with the laboratory results but with these ‘conventional’ equations. Therefore modification efforts are spent to find better equations. Comparisons between measured data (coal samples taken from two coal seams in the field) and calculated data show that only equation for ash contents gives accurate results. The other proximate analysis output data - i.e. moisture contents, volatile matter, and fixed carbon – is at considerable odd with their corresponding calculated data. Modification upon the original empirical models is then carried out. The following modifications on the equations have produced analogous but different empirical equations to the original equations. These equations certainly work more reliably for the field’s coals, and these better results underline that future log analyses in the field have to use the modified equations

Published: March 2022

Due to the excessive use of inorganic fertilizers, the structure of the soil is deteriorated, and the product quality is adversely affected. For this reason, the use of environmentally friendly organic fertilizers in production has increased in recent years. A field experiment was conducted in a plastic greenhouse in the Research Center Field at General Directorate of Agriculture, Dohuk Governorate, Northern region of Iraq during autumn season of 2020 to examine the effect of soil application of the biofertilizer (Corabac) with three levels (0, 5 and 10 g L-1) and foliar spraying with the seaweed (algal extract) at three concentrations (0, 4 and 8 g L-1) and the inorganic fertilizer at two concentrations (0 and 1 g L-1 (N:P:K 10:10:10)) compared with control (without treatment) on growth and yield of lettuce crop (Lactuca sativa L.). The obtained data indicated that the application of the three fertilizers and their interactions significantly induced vegetative growth parameters like stem length and leaf number per plant but did not positively affected leaf area (cm2) and chlorophyll content (%). Head weight (kg), yield (kg m-2), and total yield (ton ha-1) were also notably increased due to soil addition of biofertilizer and foliar spraying of the algal extract and inorganic fertilizer as compared to the control. Biofertilizer, seaweed and inorganic fertilization affected the N, P and K content in lettuce leaves. For a sustainable production in greenhouse lettuce, it is possible to obtain higher head weight and therefore higher yield by using seaweed and biofertilizers, which are considered environmentally friendly.

Published: March 2022

Two of the most important ingredients to add functional properties to royal jelly are 10-HDA and major royal jelly proteins (MRJPs). The effect of royal jelly (RJ) production and the effect of royal jelly harvest time (24, 48 and 72 hours) on 10-HDA, the total protein content of RJ, and molecular weights of major proteins in RJ were investigated in queenright and queenless colonies. RJ production colonies were divided into 2 groups as queenless and queenright where the queen was confined with frames. Subgroups were formed within each group (queenless and queenright) according to harvest time (24, 48 and 72 hours). 80 larvae were transferred to each colony. In this study, as the harvest time increased, total protein (TP) ratio decreased (p<0.05); TP ratio in RJs harvested at 24, 48 and 72 hours was determined as 18.4±1.24%, 15.2±0.80%, 10.6±0.27%, respectively. As the harvest time increased, 10-HDA decreased. It was determined 10-HDA rates in RJ harvested at 24, 48 and 72 hours respectively; 2.52±0.109%, 2.20±0.110%, 2.00±0.112%. MRJP1, MRJP2, MRJP3 and MRJP5 were found from the MRJP family, and their molecular weights were determined as 53 kDa, 46.5 kDa, 66.8 kDa, 80.9 kDa, respectively. As a result, the early harvested (24 and 48 hours) RJ had higher values in terms of TP and trans 10-HDA than the royal jelly harvested at 72 hours.

Authors: Branch-Mueller Jennifer , De Groot Joanne
Published: March 2022

This study contributes to our understanding of the early experiences of teacher-librarians and brings in the framework of possible and provisional selves as a lens to examine teacher-librarian identity. Participants told us their strongest memories included professional development, advocacy, professional change, making the library a safe space focused on learning, supporting staff and students in taking risks, and collection development. Barriers and challenges included technology, library time and budget cuts, making changes in the library, and sharing the TL position with another teacher. We saw these teacher -librarians modeling, presenting, providing evidence, creating safe learning spaces, helping staff take risks, becoming more confident in their abilities, and meeting the needs of their school community.

Steeped in the language of social justice and inclusive of the American Association of School Librarians’ Standards for the 21st Century Learner (2009) and International Federation of LibraryAssociations’ School Library Guidelines (2015), an analysis of findings bring attention to the impact highly effective partnerships have on implementing literature discussion circles and Socratic Seminars to provide a platform of expression for young adult voices seldom heard.
Supporting STEM Education: Needs Assessment of Southeastern Rural Teacher Librarians
Authors: Johnston Melissa P.
Published: March 2022

A current focus in schools in the United States is STEM education, which prepares students for successful employment and post-secondary studies that require unique and more-technically advanced skills through teaching and learning in the areas of science, technology, engineering, and mathematics (STEM). This approach is grounded in problem solving, discovery, and exploratory learning, which requires students to actively engage in a situation in order to find its solution. Students engage in STEM learning in many different ways, with technology and digital resources playing an important role. The prominence of technology in STEM education provides leadership opportunities for teacher librarians. Yet, teacher librarians must be prepared to lead in the integration of technology to support STEM education. This report presents identified needs of teacher librarians in regards to supporting STEM education and discusses implications for better preparing pre-service teacher librarians to lead in order to address the needs of a new generation of learners.
