The article is devoted to the actual problem of improving the management of social agencies since the stability, efficiency and attractiveness of any organization depends on the personnel and the management system. The purpose of the article was to outline and characterize the directions for improvement of the components of social agency management, taking into account the analysis of problem areas of the Kharkiv city center of social agencies "Dovira". By applying methods of generalization and grouping, as well as document analysis (reports after the practice of 4th-year students studying under the "Social Work" educational program) and discussions with specialists and stakeholders, two groups of problems related to management were identified: 1) problems of technical and material support and 2) problems of personnel work. Based on them, the authors of the article proposed to analyze three blocks: 1) problems of material and technical content (working conditions); 2) personnel management problems; 3) problems of protection and development of personal qualities of specialists. Their prerequisites were determined and measures to improve the social agency management system were proposed. A conclusion was made about the need to develop a management model with coordination of the following levels: the first – monitoring of the personal condition, needs and capabilities of social work specialists. Building on this basis programs of individual and group assistance and development. The second is management of the organization – development and implementation of personnel policy, taking into account the requirements and proposals of the first level. The third level is "external management" – the development of cooperation with domestic and foreign partners, lobbying of interests and the initiation of necessary and justified changes (on the basis of conclusions from the previous levels) in normative documents regulating the work of social work specialists and the activities of the organization as a whole.

RESUMENEl currículum integrado en las escuelas rurales supone una oferta global que transciende a la perspectiva metodológica convencionalmente adoptada. Siguiendo las conclusiones obtenidas en investigaciones previas en torno a currículum, práctica docente y materiales curriculares, se plantea el presente estudio organizado en fases, cuyo propósito fundamental es conocer experiencias que innovan los procesos en la escuela rural, en concreto, estudios de caso de dos centros andaluces que desarrollan proyectos de trabajo. Se identifican aquellos elementos que promueven el cambio en la acción cotidiana a partir de datos obtenidos con distintas fuentes de naturaleza cualitativa. Esta información se sistematiza en unidades de análisis o categorías. Entre los resultados destaca la dificultad que engloba adoptar un modelo curricular alternativo, comprobándose que no existe un patrón uniforme aunque se evidencien algunas referencias como la implicación del profesorado; la apertura al medio; la presión del cambio por factores eficientistas y de resultados cortoplacistas; y, la evolución progresiva no radical de la innovación. Algunas conclusiones indican que el desarrollo de una escuela rural transformadora, comunitaria y participativa, no solo tiene en cuenta los aspectos académicos, también se relaciona con el compromiso social, cultural y de calidad de vida del entorno.Palabras Clave: escuela rural, innovación educativa, currículum integrado, aprendizaje colaborativo, proyectos de trabajo.ABSTRACTAn integrated curriculum in rural schools supposes an offer that transcends perspective methodology, which is conventionally used. Following the obtained conclusion in previous investigations surrounding the curriculum, the teaching practice and curricular materials, the following study is laid out in phases, with the primary purpose being to get to know alternative experiences that innovate the process in rural schools, specifically, two case studies belonging to andalusian schools that develop working projects. The elements that foster it and the process of change in the everyday activity are identified from data obtained from different sources of a quality nature. This information is synthesized in analysis units or categories. The results show the difficulty of assuming an alternative curricular model, there is no uniform pattern although include references such as the involvement of teachers, opening to the environment, pressure of change by efficiency factors and short-term results, and innovation progressive evolution.

Characterizing Infrasound Station Frequency Response Using Large Earthquakes and Colocated Seismometers
Authors: Fee David , Macpherson Kenneth , Gabrielson Thomas
Published: February 2023

Earthquakes generate infrasound in multiple ways. Acoustic coupling at the surface from vertical seismic velocity, termed local infrasound, is often recorded by infrasound sensors but has seen relatively little study. Over 140 infrasound stations have recently been deployed in Alaska. Most of these stations have single sensors, rather than arrays, and were originally installed as part of the EarthScope Transportable Array. The single sensor nature, paucity of ground-truth signals, and remoteness makes evaluating their data quality and utility challenging. In addition, despite notable recent advances, infrasound calibration and frequency response evaluation remains challenging, particularly for large networks and retrospective analysis of sensors already installed. Here, we examine local seismoacoustic coupling on colocated seismic and infrasound stations in Alaska. Numerous large earthquakes across the region in recent years generated considerable vertical seismic velocity and local infrasound that were recorded on colocated sensors. We build on previous work and evaluate the full infrasound station frequency response using seismoacoustic coupled waves. By employing targeted signal processing techniques, we show that a single seismometer may be sufficient for characterizing the response of an entire nearby infrasound array. We find that good low frequency (<1 Hz) infrasound station response estimates can be derived from large (Mw>7) earthquakes out to at least 1500 km. High infrasound noise levels at some stations and seismic-wave energy focused at low frequencies limit our response estimates. The response of multiple stations in Alaska is found to differ considerably from their metadata and are related to improper installation and erroneous metadata. Our method provides a robust way to remotely examine infrasound station frequency response and examine seismoacoustic coupling, which is being increasingly used in airborne infrasound observations, earthquake magnitude estimation, and other applications.
European Integration Viewed through the Postwar Transnational ‘Abendland’ Movement: With Special Reference to the Centre Européen de Documentation et d'Information(CEDI) of the 1950s and 1960s
Authors:   The Korean Society For German History, Park Hye Jeong
Published: February 2023

The central piece of the postwar Abendland movement was European integration. The historical origin of this European vision can be found in the idea of Abendland itself, which departs from the ideal of the Sacrum Imperium of the Middle Age. However, the path, on which the postwar Abendland movement had walked down as an organization in the process of its transformation into an European integration movement was extremely rugged. The so-called CEDI was cast to European stage when it was launched, and thereafter had to switch its partners multiple times in order to survive as an organization in the middle of the stormy conjuncture of the Cold War era. Its agenda was much more transnational, compared to another European movement organization based in West-Germany, i.e. Europa-Union, which belonged to the main stream movement aiming at founding a United States of Europe. The clearest transnationality of the CEDI lies in its persistent focus on the Central and Eastern Europe and the political goal of setting this region free from the Soviet’s claw.
The decisive move of the CEDI towards this ultimate goal was the organizational merge with Paneuropean Union in 1972. The CEDI already restored its ancient pivot of the Abendland, i.e. the Central and Eastern Europe, as its main agenda through the collaboration with De Gaul France government, and it did not lose sight of this pivot again even after they split. Eventually since the CEDI merged with PEU, it properly start collaborating with the expellee’s association in West-Germany and its efforts to realize the agenda of ‘christliches Großeuropa’ led to the historical event, the Paneuropean Picnic in 1989, which made the first kick to tear down the iron curtain.

In this research, the circulation weather types (CWTs) associated with individual surface pressure data at different atmospheric heights were used to correlate and quantify soil erosion events collecting soil loss (g m-2), runoff (l m-2) and sediment concentration (g L-1) using field plots and sediment collectors. Representative Mediterranean shrubland, located at Sierra de Enguera (Eastern Spain), was used as a case study where 213 rainfall episodes and related soil loss events were recorded for the 2010-2014 period. Average annual precipitation of 544 mm was registered, summarizing a total of 2,720.1 mm for the five years of the research period. A total of 34.4% of the registered precipitation events ranged from 10 to 29.9 mm, 23.5% from 30 to 49.9 mm, and 15.9% from 50 to 99.9 mm. The dynamic low-pressure with fronts (DLp+f) CWT was found to generate the highest precipitation amount reaching 60.6% of the total precipitation (105 of the 213 events). Over a third (35%) of the precipitation events occurred during Eastern CWT, which accounted for 48% of the total precipitation with average values of 17.6 mm per event. From the total runoff, 65.6% was related to the combined Eastern and cold drops (CD) CWT. The DLp+f CWT was found to produce 48.9% of sediment mobilization, of which 73.5% of this amount was generated by Eastern CWT. The highest sediment concentration event was found for the southern CWT under thermal low-pressure (TLp) reaching 51.65 g L-1, followed by A (anticyclones) with the Eastern CWT (42.23 g L-1). As a whole, the southern is the CWT generating the highest average sediment concentration (28.66 g L-1), followed by Easter CWT. Our findings suggest that CWTs contribute to foreseeing the periods with the highest soil losses and may help to prevent them. We discuss the need to analyse the changes in soil erosion rates due to CWT to better characterize the soil erosion process and assess the soil erosion rates, improve the current soil erosion models and investigate how climate change is changing the role CWT plays in runoff initiation and sediment delivery.

Published: February 2023

Purpose: To investigate and optimize the accuracy of aphakic refraction (AR) techniques for secondary intraocular lens (IOL) power calculation in aphakic children.Methods: Thirty-three aphakic eyes of 18 patients who were candidates for secondary IOL implantation were enrolled in the present study. Axial length (AL) measured by optical biometry was used in the biometric formula (SRK-T, Holladay II, and Hoffer-Q). AR and spherical equivalent (SE) were used in two AR-based formulas (Ianchulev, Leccissotti). True power was calculated based on postoperative SE at three months’ follow-up. Results: Regarding the postoperative SE, 13 (40%) eyes were within ±1.00 diopters (D) and 22 (66%) were within ±2.00 D. Median absolute error (MedAE) was predicted to be 4.4 and 7.3 D with the use of Ianchulev and Leccissotti formulas, respectively. The corresponding value was 0.8 D with the biometric formula. All eyes were deemed to have myopic refraction when using the AR-based formulas except one eye with the Ianchulev formula. The coefficient of our modified formula was 1.7 instead of 2.01 in the Ianchulev formula. MedAE with the use of new formulae was 0.5 D and was comparable with the true IOL power (P = 0.22). Conclusion: Both Ianchulev and Leccissotti formulas resulted in a significant myopic surprise in aphakic children aged between 4.5 and 14 years. The modified formula proved to determine a more accurate SE that is comparable with biometric formulas.

Authors: Hejazi Marjaneh , Razaghi Ghazale , Aghsaei Fard Masoud
Published: February 2023

Purpose: In this study, an algorithm based on deep learning was presented to reduce the retinal nerve fiber layer (RNFL) segmentation errors in spectral domain optical coherence tomography (SD-OCT) scans using ophthalmologists’ manual segmentation as a reference standard. Methods: In this study, we developed an image segmentation network based on deep learning to automatically identify the RNFL thickness from B-scans obtained with SD-OCT. The scans were collected from Farabi Eye Hospital (500 B-scans were used for training, while 50 were used for testing). To remove the speckle noise from the images, preprocessing was applied before training, and postprocessing was performed to fill any discontinuities that might exist. Afterward, output masks were analyzed for their average thickness. Finally, the calculation of mean absolute error between predicted and ground truth RNFL thickness was performed. Results: Based on the testing database, SD-OCT segmentation had an average dice similarity coefficient of 0.91, and thickness estimation had a mean absolute error of 2.23 ± 2.1 μm. As compared to conventional OCT software algorithms, deep learning predictions were better correlated with the best available estimate during the test period (r2 = 0.99 vs r2 = 0.88, respectively; P < 0.001). Conclusion: Our experimental results demonstrate effective and precise segmentation of the RNFL layer with the coefficient of 0.91 and reliable thickness prediction with MAE 2.23 ± 2.1 μm in SD-OCT B-scans. Performance is comparable with human annotation of the RNFL layer and other algorithms according to the correlation coefficient of 0.99 and 0.88, respectively, while artifacts and errors are evident.

Authors: Sharma Ashok , Sharma Rajan , S. Nirankari Verinder
Published: February 2023

Purpose: To describe a new method of treatment of corneal perforation with extensive corneoscleral melt. Case Report: A 42-year-old man presented with moderate-sized (3.5 mm) corneal perforation with extensive corneo-limbo-scleral ulceration following bare sclera excision of pterygium. No prior use of antimetabolites or postoperative beta radiation noted. We considered retrocorneal sclera patch supported cyanoacrylate application. The sclera was thinned to one-third thickness and a patch (4.5×4.5 mm) was punched. The sclera patch was placed on the iris, behind the corneal perforation, adequately covering it from inside. A minimal amount of adhesive was applied on the retrocorneal sclera patch and margin of corneal perforation. The ulcerating sclera was covered with double layered amniotic membrane. Topical antibiotic, steroid, and cycloplegic drops were instilled thrice daily. Corneal perforation healed and no recurrence occurred during the 18 months’ follow-up. Conclusion: Retrocorneal scleral patch supported cyanoacrylate is effective for corneal perforation with corneo-scleral melt.

Nowe dylematy medycyny – zjawisko macierzyństwa zastępczego w perspektywie społeczno-etycznej
Authors: Walerjan Bożena
Published: February 2023

Contemporary medicine offers more and more possibilities as far as procreation is concerned. They are available, first of all, to infertile couples (IVF – In Vitro Fertilization). However, the advanced reproductive technology is also used by people who are biologically capable of having children. These people are ready to resign voluntarily from pregnancy and childbirth difficulties. The surrogate motherhood appears as a phenomenon known already from biblical times but existing nowadays in a different context. At the same time, some issues are emerging – questions concerning social, ethical, moral and legal consequences. This paper presents the issue of surrogate motherhood in the context of social changes, which could lead to a development of such practices as well as the reasons of parents and surrogate mothers. Can this phenomenon be perceived as a service for people who want to fulfill their desires for having children? Would surrogate motherhood become a socially approved practice? What are the ethical, religious and legal norms concerning this phenomenon? The religious norms are connected, first of all, with an attitude of the Catholic Church which recognizes surrogacy as unacceptable and states that “it offends the dignity and the right of a child to be conceived, carried in the womb, delivered to the world and brought up by their own parents”. The ethical norms refer to the biotechnological issues and include matters of creating and implanting human embryos as well as the problem of the surrogate mother – child – biological parents relationship. As far as legal norms are concerned, the case is still open hence Polish law does not take into consideration in vitro fertilization or the admissibility of surrogate motherhood.
Etyczne i wychowawcze aspekty opinii publicznej
Authors: Lepa Bp Adam
Published: February 2023

This paper is concerned with the issue of public opinion considered from two points of view: ethical and educational. It has been inspired by the insufficient knowledge of society about public opinion as well as the gullibility of the general public as regards the acceptance of the results of public opinion polls. Therefore, the ethical and
educational dimension of this phenomenon are not recognized, which results in a severe lack of
research and publications on the topic.
The paper consists of three parts. The first part introduces basic facts about public opinion and its major
mechanisms. The second one deals with the phenomenon of public opinion as an ethical problem, while the third
one is devoted to the problem of education aimed at the development of mature perception of public opinion and
active participation in the process.
The problem of public opinion is treated as an important and urgent task for ethicists and teachers. This
seems relevant as an increasing influence of public opinion on both individuals and a whole society is observed in
various areas, including politics, economy, culture and trade. Public opinion also affects an information order,
which is of significance to the state and its citizens in the light of the emergence of a communication society.

Este trabajo estima los efectos derrame o de spillovers asociados al inadecuado comportamiento de las personas (debido al incumplimiento del confinamiento laboral y de la protección en salud) sobre la pobreza monetaria del Perú en el período COVID-19 entre el trimestre 2020.II al trimestre 2021.IV. Para ello usa un diseño no experimental de Control Sintético con Spillovers desarrollado por Cao y Dowd (2022). Estos efectos son medidos para 59 provincias, denominadas de tratamiento por tener una tasa de contagiados por COVID-19 mayor al 1%, y 31 provincias denominadas de control con tasas de contagiados por COVID-19 menores o iguales al 1%. De las estimaciones se obtiene que diecisiete provincias tratadas tuvieron efectos spillovers estadísticamente significativos en por lo menos un criterio de las 9 fuentes de spillovers. En promedio para las 17 provincias, cerca del 33% del incremento de la pobreza en el periodo COVID-19 se explica por los efectos spillovers asociados al inadecuado comportamiento de las personas.
Farmers’ knowledge on fall armyworm (spodoptera frugiperda) pesticide application and its relationship with quantity of maize that is lost to fall armyworm
Authors: Baidoo Jacqueline , Quansah Alex , Kwapong Keneth
Published: February 2023

Fall armyworm (Spodoptera frugiperda) has spread rapidly and posed numerous threats to the food security and livelihood of millions of smallholder farmers in Ghana. This study quantifies the damages of fall armyworm infestation in maize production and identifies the various methods used in controlling fall armyworm infestation. Almost all farmers 94% experienced fall armyworm infestation on their farms. They cited key common visual damages as yellowish leaves, stunted growth, poor yield quality, holes in leaves, and egg masses on leaves. Farmer’s loss an average of GH¢2616.07 to fall armyworm infestation. Pesticide application is the frequent control measure mostly used by farmers. Farmers do not mostly use biological methods for the control of the fall armyworm. The use of pesticide as a control method is however not effective as about GH¢ 3 000 per 1 acre is lost with the use of insecticides. It is recommended that the use of other control measures like the contemporary measures involving the use of birds and chickens as predators of eggs and worms of fall armyworm should be encouraged.

Published: February 2023

"El parkinsonismo es un conjunto de trastornos neurodegenerativos del sistema nervioso central y periférico, que produce, además de movimientos anómalos, una variedad de alteraciones a nivel ocular y visoperceptual. Existen varias patologías que pueden cursar con el parkinsonismo: Parkinson idiopático, Parkinson con demencia con cuerpos de Lewy, y degeneración corticobasal, entre otras; dolencias que pueden ser confundidas por sus semejanzas en cuanto a manifestaciones motoras, aunque se ha reportado que estas podrían suponer alteraciones visoperceptuales diferentes. El objetivo del presente estudio es caracterizar las disfunciones visoperceptuales asociadas al Parkinson idiopático y la demencia con cuerpos de Lewy, estudiadas en la literatura científica. Se realizó una revisión narrativa de literatura de 20 artículos publicados entre los años 1997 y 2019, en idioma inglés. Dichos artículos fueron evaluados con la herramienta de lectura crítica Caspe. Quince artículos reportaron disfunciones visoperceptuales en parkinsonismo idiopático, tres tanto en Parkinson idiopático como en demencia con cuerpos de Lewy, y dos solo en demencia con cuerpos de Lewy. En conclusión, en las investigaciones sobre Parkinson idiopático, se detectaron principalmente alteraciones de la percepción visoespacial, mientras que en las de demencia con cuerpos de Lewy, la principal alteración visoperceptual correspondió a las alucinaciones visuales."
Mechanisms that stabilize human walking
Authors: Van Leeuwen Moira , Bruijn Sjoerd , Van Dieën Jaap
Published: February 2023

In this paper we review what mechanisms are used to stabilize human bipedal gait. Based on mechanical reasoning, potential mechanisms to control the body center of mass trajectory are modulation of foot placement, stance leg control consisting of modulation of ankle moments and push-off forces, and modulations of the body’s angular momentum. The first two mechanisms and especially the first are dominant in controlling center of mass accelerations during gait, while angular momentum control plays a lesser role, but may be important to control body alignment and orientation. The same control mechanisms stabilize both steady-state and perturbed gait in both the mediolateral and antero-posterior directions. Control is at least in part active and is affected by proprioceptive, visual and vestibular information. Results support that this reflects a feedback process in which sensory information is used to obtain an estimate of the center of mass state based on which foot placement and ankle moments are modulated. These active feedback mechanisms suggest training approaches for populations at risk of falling, such as augmenting their effective use by means of augmented feedback, or using their complementary nature to train one mechanism by constraining the other mechanisms.
Gait velocity and stability are correlated to muscle and bone mass loss in people with Parkinson’s disease: a preliminary study
Authors: Barbieri Fabio A. , Faria Murilo H. , Similei Lucas , Penedo Tiago , Kalva Filho Carlos A. , Beretta Victor S.
Published: February 2023

Background: Parkinson’s disease (PD) exacerbates muscle and bone mass loss, which is associated with several negative outcomes such as falls and disability. Thus, muscle and bone mass loss may be one mechanism for the mediator role between gait impairments and PD. Aim: To verify the relationship between the spatial-temporal gait parameters and the body composition of the lower limbs in people with PD. Method: Thirteen people with PD were evaluated on two different days: i) clinical and gait evaluation; ii) body composition evaluation. The step length, width, duration and speed, the percentage in double support, and gait velocity during walking at self-selected velocity. Dual-energy X-ray absorptiometry technique was used to measure fat mass, lean mass, bone mass, and the total mass, for whole body, and separately for each limb. Pearson’s correlation coefficients were applied between the spatial-temporal gait parameters and the variables of body composition of lower limbs. Results: Reduced lean and bone mass of both legs were related to faster gait velocity (r=0.6, p<0.03 and r=0.7, p<0.01, respectively) and step speed (r=0.5, p<0.05 and r=0.65, p<0.02, respectively). Also, narrower step width was related to the higher bone mass of both legs (r=0.6, p<0.03). However, muscle and bone mass did not correlate with step length and duration, and percentage of double support. Interpretation:Our findings suggest that the muscle and bone mass of the lower limbs are important body characteristics for gait impairments in people with PD and should be monitored over the disease.

The Canada Goose Branta canadensis occurs in a feral state in New Zealand and rarely strays to Australia. There are two mainland records for Australia. The second of these pertains to four birds that were first observed on the south coast of New South Wales (NSW) in late 2007 before eventually being culled at Killalea State Park, NSW, in early March 2008. These specimens, three females and a male, the first from Australia, were incorporated into the collection of the Australian Museum. They are considered to have been free-flying adults of the subspecies B. c. maxima, that which occurs in New Zealand, from where they are assumed to have originated. The destruction of these Geese was consistent with guidelines for dealing with any appearance of this invasive species in Australia.
An Integral Expression for Pi Obtained by Virtue of Ramanujan’s Approximation in Conoidal Areas: Applications of the Resultant Figure in Engineering
Authors: Cabeza Lainez Joseph
Published: February 2023

unlike the volume, the expression for the surface area of a regular conoid has not yet been obtained by means of direct integration or a differential geometry procedure. As this non-developable form is relatively used in engineering, the difficulty to determine its surface, represents a serious shortcoming for several problems which arise in radiative transfer, lighting and construction, to cite just a few. In order to solve the problem, I conceived the surface as a set of linearly dwindling ellipses which remain parallel to a circular directrix, a typical problem appears when searching the length of such ellipses. I employed a new procedure which, in principle, consists in dividing the surface into infinitesimal elliptic strips to which we have successively applied Ramanujan’s second approximation for the longitude of the ellipse. In this manner, we can obtain the perimeter of any transversal curve pertaining to the said form as a function of the radius of the directrix and the position of the ellipse’s center on the X-axis. Integrating the so-found perimeters of the differential strips for the whole span of the conoid, an unexpected solution emerges through the newly found number psi (ψ) which seems like a refined approximation to the third decimal of Pi but derived from a definite integral equation. As the strips are in truth slanted in the symmetry axis, their width is not uniform and we need to perform some adjustments in order to complete the problem with sufficient precision, but this is discussed separately in the annexes. Relevant implications for mathematical symmetry applied to multifarious architectural and engineering forms can be derived from this finding

As a rapidly growing coastal megacity, Shanghai is continuously threatened with land subsidence issues since 1920s. Land subsidence was controlled in 1960s, however in 1990s, unconscious and dangerous urban underground space (UUS) exploration and tunneling development are causing further land subsidence. It is imperative to study previous relations towards future adaptive and resilient scenario modelling and planning. There are multiple cause-effect factors determined in the urban built environment of Shanghai megacity. This paper presents the current evidence based on the relations of the multifactor of the spectrum. Methods consist of understanding the cause-effect relations and spatiotemporal from the crucial period of 1960-2020. Data are collected secondarily from multiple open sourced databases. The results determine Shanghai are highly influenced by the UUS development induced-subsidence, tunneling leakage and weak spatial modelling. Spatiotemporal pattern has shown a mixed positive-negative impact: population, land subsidence is growing in parallel distribution (positive) with tunneling leakage, construction of tunneling, metro system, UUS development, building price, reconstruction area, GDP growth, land price, arable land decrease and further tunnel settlement in Urban City Centre, Pudong New Area, Minhang, Baoshan and Songjiang districts. These results are useful for further adaptive and resilient scenario modelling and spatial planning.
Structural Insights into Electrophiles and Electrophilic Metabolites Sensing and Signaling: The Missing Information
Authors: Rogg Chloé , Aye Yimon
Published: February 2023

Native reactive electrophile species (RES) are long-recognized regulators of pathophysiology; yet, knowledge surrounding how RES regulate context-specific biology remains limited. The latest technological advances in profiling and precision decoding of RES sensing and signaling have begun to bring about improved understanding of localized RES regulatory paradigms. However, studies in purified systems—prerequisites for gaining structure/function insights—prove challenging. We here introduce emerging chemical biology tools available to probe RES signaling, and the new knowledge that these tools have brought to the field. We next discuss existing structural data of RES-sensor proteins complexed with electrophilic metabolites or small molecule drugs (limited to < 300 Da), including challenges faced in acquiring homogenous RES-bound proteins. We further offer considerations that could promote enhanced understanding of RES regulation derived from three-dimensional structures of RES-modified proteins.

Advancements in Machine Learning techniques, availability of more data-sets, and increased computing power have enabled a significant growth in a number research areas. Predicting, detecting and classifying complex events in earth systems which by nature are difficult to model is one of such areas. In this work, we investigate the application of different machine learning techniques for detecting and identifying extreme rainfall events in a sub-catchment within Pangani River Basin, found in Northern Tanzania. Identification and prediction of extreme rainfall event is a preliminary crucial task towards success in predicting rainfall-induced river floods. To identify a rain condition in the selected sub-catchment, we use data from five weather stations which have been labeled for the whole sub-catchment. In order to assess which Machine Learning technique suits better for rainfall identification, we apply five different algorithms in a historical dataset for the period of 1979 to 2014. We evaluate the performance of the models in terms of precision and recall, reporting Random Forest and XGBoost as the ones with best overall performance. However, since the class distribution is imbalanced, the generic Multi-layer Perceptron performs best when identifying the heavy rainfall events, which are eventually the main cause of rainfall-induced river floods in the Pangani River Basin
Special-Oriented Annealing Twins Induced Orange Peel Morphology of Heat Pipe under Bending Deformation

Published: February 2023

Thin-wall heat pipe is an efficient heat transfer component, which has been widely used in the field of heat dissipation of high-power electronic equipment in recent years. In this study, the orange peel morphology defect of thin-wall heat pipes after bending deformation was analyzed both for the macro 3D profile and for the micro-formation mechanism. The results show that after high temperature sintering treatment, the matrix grains of heat pipe are coarsened seriously and formed a strong Goss texture, while a certain annealing twins with the unique Copper orientation are retained. The distribution of Schmid factor value subjected to the uniaxial stress indicate the inhomogeneity of intergranular deformation exist among the annealing twins and matrix grains. The annealing twin exhibit a “hard-oriented” component during the deformation; thus, it plays a role as barrier and hinder the slipping of dislocation. As the strain accumulates, part of the annealing twins may protrude from the surface of heat pipe, forming a large-scale fluctuation of the surface as the so called the “orange peel” morphology. The 3D profile shows the bulged twins mostly perpendicular to the drawing direction, with about 200-300μm in width and 10-20μm in height.

A unique two-column 230U/226Th generator has been developed. The focus was hold on obtaining 226Th of high purity in a solution amenable to further labeling. The first column of the proposed generator filled with TEVA Resin held 230U, from which 226Th was eluted with 7 M HCl solution. UTEVA Resin pretreated with nitric acid solution was used as a sorbent for the second column for thorium retention. 226Th was extracted with 0.01-0.05 M citric buffer solution. One cycle of generator milking took 5-7 minutes and produced > 90% of 226Th in 1.5 ml of eluate, pH 4.5-5.0. The proposed two-column 230U/226Th generator was tested over two months including a second loading of 230U additionally accumulated from 230Pa. The 230U impurity in 226Th eluate was less than 0.01% allowing to use it directly in synthesis of radiopharmaceutical compounds.

Unlike aerial or terrestrial navigation, the Global Navigation satellite system (GNSS) is not available underwater. This is a big challenge for underwater navigation. The inertial navigation system (INS) aided by the single-beacon acoustic positioning system (APS) provides one solution, but the long-range case is limited by low SNR conditions. Inspired by passive synthetic aperture detection, we proposed a new tightly coupled navigation algorithm based on spatial synthesis and one-way-travel-time (OWTT) range measurement. We design two estimators: the DOA/Range estimator using the model-based method and the tightly coupled INS/APS navigation estimator. Based on the improved UKF, all information is combined. Simulation is carried out in MATLAB. Compared with range-only tightly coupled INS/APS navigation, synthetic long baseline (SLBL) algorithm and Doppler velocity logger (DVL) aided centralized extended Kalman filter (CEKF) based single beacon INS/OWTT navigation, the proposed method's performance is proven. The main contributions of this work are: 1. Propose a new architecture of underwater integrated navigation; 2. Apply the passive acoustic detecting method in the navigation to improve accuracy. 3. Apply the tightly coupled method to improve availability.
Control of Mortality by Human Serum Albumin

Published: February 2023

Human serum albumin (HSA) is the ultimate, homeostatic determinant of fluid volume (FV) in all compartments of the body. The ability to change the pressure and flow of nutrient medium to cellular structures selectively has clinical significance in almost all areas of clinical medicine. We have shown that present fluid therapy (FT) using either colloid or saline dilutes nutrients. HSA binds and delivers nutrients, a lack of HSA binding causes Albumin Binding Disease (ABD) changing both colloidal pressure and nutrients leading to symptoms of sepsis. A reduction in HSA binding can be through lack of HSA or external ligands taking up binding sites on HSA. Many diseases cause ABD when immunoglobulins, infectious particles and by products bind to HSA including COVID-19 and other bacterial diseases like streptococcus as well as metabolic and cardiac disease due to incorrect pressure and nutrients. To raise HSA binding potential and remove vulnerabilities to these diseases we propose raising HSA. We show how present methods of fluid therapy (FT) are inefficient in that control of both pressure and nutrients forms initial equilibrium in the liver. HSA production and binding to nutrients is maintained at a level by the pressure in hepatocytes with the pancreatic and adrenal hormones moderating. Glucose and Ke-tone production are critical in the management of HSA binding and control of blood, colloidal pressure, and health of cells. Ketones provide a distinct mechanism of liver to lungs-heart metabolism during hypoglycaemia and activity. This known chain of nutrition becomes critical during disease like acute respiratory distress syndrome (ARDS) when ketones may be overproduced. HSA must therefore be infused into the liver to raise HSA levels safely. We investigated the control of HSA as a product of the actions of pressure in hepatocytes and changes in pancreatic and adrenal hormones. We found that in addition to pressure during glucose abundancy HSA is re-leased with ketones on administration of insulin and consider that this mechanism retains HSA moderation. HSA can therefore be increased by increasing insulin in the presence of glucose in the correct amounts. We suggest a protocol to increase FV, blood, lymph volume by infusion of HSA, insulin, and glucose direct to the liver so that the level of HSA stabilises. We suggest this will raise all other nutrients in the new FV, blood, lymph culminating in the creation of new blood cells. We propose that in a clinical situation maintaining this protocol will alleviate the symptoms of ABD and decrease the likelihood of serious illness and death.
