Abstract

Objectives
The availability of appropriate conduits remains an obstacle for successful reconstruction of long-distance nerve defects. In previous sheep trials, we were able to bridge 6 cm nerve gaps with nerve conduits based on spider silk fibers with full functional outcomes. Here, we describe the first application of spider silk for nerve repair in humans.

Methods
Four patients with extended nerve defects (>20 cm) underwent nerve reconstruction by interposition of conduits that were composed of spider silk fibers contained in autologous veins. The longitudinal luminal fibers (approx. 2500 fibers per graft) consisted of drag line silk from Trichonephila spiders. All patients were evaluated between 2 and 10 years postreconstruction, clinically, and by neurography.

Results
In all patients, primary wound healing and no adverse reactions to the implanted spider silk material were observed. Patients regained the following relevant functions: protective sensibility, full flexor function with near-normal grasp and powerful function after microvascular gracilis muscle transfer, and key grip function and gross finger flexion after additional tenodesis. One patient with sciatic nerve reconstruction developed protective sensibility of the lower leg, foot, and gait, enabling normal walking and jogging. No neuroma formation or neuropathic or chronic pain occurred in any of the patients.

Conclusions
For patients with extended peripheral nerve defects in the extremities, use of conduits based on spider silk fibers offers the possibility of restoring sensory function and protection from neuroma. This kind of nerve bridges provides new perspectives for the reconstruction of complex and long-distance nerve defects.
Homogeneity Pursuit in the Functional-Coefficient Quantile Regression Model for Panel Data with Censored Data

Published: July 2024

Abstract
Homogeneity identification of panel data models has been popular in the literature in recent years. Most of the existing works only focus on the complete data case. This paper considers a functional-coefficient quantile regression model for panel data with homogeneity when its response variables are subject to censoring. In particular, we consider a more general censoring framework, i.e. different types of censoring are allowed to occur in the model simultaneously. For this, a “three-stage” method is proposed, which includes the preliminary estimation of subject-specific function coefficients based on data augmentation, the identification of group structure over subjects by clustering, and post-grouping estimation of function coefficients. Simulation studies considering the left-, right-, and double-censored data, are carried out to verify the finite-sample properties of the proposed method. Simulation results show that our method gives comparable performance to the complete data case. The application to the bank stock data further illustrates the practical advantages of this method.
A Discussion of the Combined Effect of Resistance Training and Time-Restricted Eating on Body Composition and Neuromuscular Adaptations

Published: July 2024

ABSTRACT
Time-restricted eating (TRE) is an application of intermittent fasting where an individual consumes their calories in a specific eating window (e.g., 8 hours) followed by a prolonged fasting window (e.g., 16 hours). Several randomized controlled trials have analyzed the combined effect of resistance training (RT) and TRE on physical adaptations, including fat mass (FM) loss, fat-free mass (FFM) retention, hypertrophy, local muscular endurance, power, and strength. In this mini review, we highlight the methodology and results from these studies and conclude by providing practical application suggestions for fitness professionals striving to maximize RT + TRE with their clientele. Generally, RT + TRE leads to positive body composition changes, including FM loss and FFM retention, which culminates in improved body fat percentage. Similarly, RT + TRE consistently stimulates positive neuromuscular adaptations, such as increased hypertrophy, local muscular endurance, power, and strength. When positive changes are not observed, and when safely implemented, RT + TRE rarely confers negative effects on the abovementioned adaptations. In short, RT + TRE may be a beneficial dietary and exercise strategy to improve body composition and muscular fitness. However, there are several caveats for practitioners to consider, which are discussed at length in this article.
Causalidad psíquica y lazo social contemporáneo
Authors: Zapata-Reinert Luz 
Published: July 2024

El informe francés del INSERM sobre el “Trastorno de comportamiento en el niño y el adolescente”, reduce la causalidad psíquica a la causalidad biológica, el síntoma al trastorno y lo psíquico a la conducta. Este informe hace tal abstracción de los fenómenos humanos que reduce todo a una lógica sin sujeto. El artículo interroga este determinismo mostrando la importancia del lenguaje y la palabra para la causalidad psíquica, la dimensión propiamente subjetiva de acuerdo al psicoanálisis.

PUPILS’ WRITTEN LANGUAGE IN THE LATVIAN LANGUAGE AND HISTORY STATE EXAMINATIONS IN LATGALE IN 2021
Authors: Straupeniece Daiga , Dzintars Normunds 
Published: July 2024

The research aims to examine pupils’ text creation skills in the Latvian language and history state examinations (CE). The source of the research is the examination papers of pupils in Latgale in 2021: Latvian language CE (a substantiated opinion; 250 words) and history CE (task 3 of part 3 – an essay; 200 words). Evaluation criteria of both examinations show that the quality of spelling is considered more important in the Latvian language examination (10 points out of 34 (approx. 30%) can be obtained for orthography and punctuation).
The article summarises the main types and number of errors in morphology and syntax in both exams. In morphology, several types of errors are distinguished: unmotivated use or absence of long characters, misspelling of consonants, errors in the spelling and hyphenation of words, misspelling of proper names, misspelling of verbs and foreign words. The number of errors in pupils‘ work was also determined for several syntactic constructions: coordinated parts of sentence, coordinated parts of sentence with a generalising word, participial clauses, insertions, and explanatory word groups. The number of punctuation errors in sentences, separating the parts of a compound sentence and a complex sentence, and unmotivated uses of punctuation were also investigated.
Comparing the quality of students’ written language in Latvian and history, it can be concluded that the quality of writing in both exams remains similar for the same student. There are pupils with no orthographic and punctuation errors in both examinations. Some students have some spelling and punctuation errors in both examinations. Some pupils have many spelling and punctuation errors in both examinations. This result is an indication that students follow spelling and punctuation norms according to their knowledge, skills, and writing culture. The study does not support the hypothesis that in the writing part of exams in subjects other than the Latvian language, pupils’ knowledge is weaker and a more negligent attitude towards writing culture would be observed.
DAILY LIFE CONTEXT BASED DIDACTIC GAMES IN MATHEMATICS LESSONS TO DEVELOP MATHEMATICAL COMPETENCE

Published: July 2024

The results of the national centralised examination of Latvia show a lack of students` mathematical knowledge, skills and competences, which can have a negative impact not only on the direction of education in future, but on students` career choice as well, which makes an impact on the number of specialists in STEM (Science; Technology; Engineering; Mathematics) field professions. Employers highlight that a lack of mathematics skills is one of the major barriers to long-term investments in science, technology, engineering, and mathematics. Consequently, the use of appropriate and varied teaching methods, e.g. integrating real-life problem situations through daily life context based didactic games into the mathematics learning process becomes important. Daily life context based didactic games provide more realistic understanding of everyday situations and examples that lead to more effective and meaningful learning of mathematics. The aim of the research is to investigate and clarify the importance of integrating real-life problem situations through daily life context based didactic games in mathematics learning to improve mathematical competence. Theoretical research methods and empirical research methods (student surveys and teacher interviews), data processing and analysis methods (quantitative, graphical data representation, data analysis) are used in the research. The analysis of the student questionnaire highlights that students do not understand the importance of mathematics in everyday life as well as have difficulties explaining the meaning of mathematical competence. While teacher interviews reveal teachers' opinions about the problems of mathematics in everyday life and the possibility of using mathematics to solve everyday problems.

Published: July 2024

Today, comprehensive measures are being implemented around the world and certain results are being achieved in the field of further deepening economic reforms in the building materials industry and the rapid development of the network, increasing the production of new modern building materials, structures and products, and expanding their range. Expanding the range of manufactured building materials, increasing the share of production of modern, convenient, and high-quality products based on a localization program, reducing imports, as well as the further development of the industry remain pressing issues of today.
The studies present methods for increasing the fire resistance of polymer building materials obtained based on fly ash from the furnaces of the Shirin Thermal Power Plant and JSC Uzmetkombinat, waste phosphogypsum generated at JSC Maxam-Ammafos, physical, mechanical, and thermodynamic properties, and also studied optimal proportions for obtaining composites of fire-resistant polymer building materials.
To conduct an experimental study, particles of technogenic industrial waste of the most optimal size, types of filler, and necessary components were selected. Studies of the elemental composition of industrial technogenic waste and X-ray diffraction analysis have shown that they consist mainly of silicon dioxide, which consists of more than 80% of the amorphous phase.
Based on the analysis of the X-ray phase structure, it was determined that the introduction of additives into the fly ash fillers of the Shirin Thermal Power Plant and Uzmetkombinat JSC, as well as phosphogypsum waste from Maxam-Ammofos JSC, leads to an increase in the thermal stability of polymer materials. The main reason for this is explained by the fact that the composition of fly ash and phosphogypsum waste introduced into the polymer composite contains metal oxides, silicon oxide, and phosphorus compounds, which are resistant to temperatures and have fire-retardant properties.
The fire resistance properties of the proposed polymer-containing building materials modified with fire-resistant compositions of the PPA, PPK and PPM brands, consisting of polymer binders, fire-retardant additives and fillers, were studied based on experimental tests, while the oxygen index was increased from 18.5 to 33.0%, while the weight loss during thermal oxidation was reduced from 97.5 to 73–75.5%, and the flammability level according to state standard 28157 was changed from PV-2 to PV-0.

THERMODYNAMIC EMPIRISM FOR DESCRIBING ATMOSPHERIC POLLUTANTS
Authors: Petrov Mihai , Nikolaeva Zdravka , Dimitrov Aleksandar , Traneva Velichka 
Published: July 2024

Humanity is currently subject to excessive pollution of the Biosphere and the atmosphere that comes from anthropogenic activity. The global warming is the most acute problem that has a negative impact on the state of the biosphere as a whole. The long empirical analysis on the state of the atmosphere makes it possible to develop quantitative expressions that give a dependence of the atmospheric temperature variation depending on the accumulation of anthropogenic polluting gases with greenhouse effect. One of the gases with a greenhouse effect is carbon dioxide, which has a major contribution to global warming. The method suggested in the paper focuses on the empirical analysis with the application of the thermodynamic laws describing the state of the atmosphere and gives the results of the validation within certain limits of the variation of the atmospheric temperature as the dependence of the accumulated concentration of the polluting gases with greenhouse effect. The relational connection between variations of concentrations and of the temperature is found by the equation of state of the ideal gas, assuming that the atmosphere can be described by this equation and the combination with the adiabatic thermodynamical equation leads to the expression which contains those variations. Annually, the monitoring stations record variations of concentrations and temperatures. The last 40 years the average temperature of the atmosphere is elevated up to 10C. The respective calculations by the application of thermodynamic expressions lead to the same order of 1 0C. It is explained by the application of thermodynamic physico-chemical laws that the rate of photosynthesis is comparatively low compared to the rate of additional excessive accumulation of carbon dioxide that comes from anthropogenic activity. The importance of the suggested method allows us to conclude about the validation of the method with the direct application of analytical expressions of the state of the atmosphere. Statistical analysis is very widely applied in general for data analysis, but it would be recommendable physico-chemical laws to be applied directly with a wider retrospective and the most important thing is that it allows the control of both the real recorded values and to be compared with those calculated by the thermodynamic method. The practical importance of this expression is based on the fact that the anthropogenic accumulation of carbon dioxide is followed by the accumulation of heat excess in the atmosphere, and in its turn to the increasing of the average global temperature of the atmosphere. one thing it is important to mention that the effect which takes place must be explained and this explanation is given by physical-chemical methods based on thermodynamic phenomena for the atmosphere.

Published: July 2024

The main objective of the present research was to apply the sustainability approach to the management of sanitation systems carried out by community-based organizations (JASS) in rural villages with the support of the district municipality. Given the limited capacity of rural district municipalities to supervise, monitor and provide technical assistance to these community organizations, a proposal for municipal technical assistance (MTA) was developed based on an index for the evaluation of the sustainability of rural sanitation systems (IESSSR). Such index allowed to evaluate not only the sustainability, but also to identify the deficient and unsustainable aspects of each system, which was crucial to develop improvement plans for each JASS. A first measurement of the sustainability of the two intervened systems was made – of the rural population centres of Palmira and Dos de Mayo, both located in the district of Leymebamba –, a general sustainability index (IGS) for JASS Palmira of 3.010 (Stable) and for Dos de Mayo of 2.997 (Unstable) were obtained. In the second measurement, using 5 dimensions, 18 factors, 48 variables and 66 indicators, the IGS of JASS Palmira was 3.179 (Stable) and that of Dos de Mayo was 3.233 (Stable). The reliability of the index was analysed using the test-retest method by comparing the May and December measurements of each JASS, obtaining a Pearson correlation index of 0.631 for Palmira and 0.602 for Dos de Mayo. Finally, the index was developed into a software application to facilitate the storage, processing, monitoring, evaluation and presentation of the information, and is currently being tested in the municipality of Leymebamba.
MATHEMATICAL MODEL EQUATION OF THE ENERGY WILLOW CUTTING UNLOADING PROCESS FROM THE SLOT HOPPER AUTOMATED PLANTER

Published: July 2024

This work is a logical continuation of the authors’ cycle of works devoted to construction of a mathematical model of the unloading process of cuttings from a slotted hopper. The purpose of the paper is a theoretical justification of the movement of an array of cuttings during gravity unloading. The article proposes consideration of the process of unloading the energy willow cuttings from the point of view of hydrodynamic multiphase systems. It is suggested to consider the set of cuttings as a pseudo-fluid consisting of two phases: discrete (cuttings) and continuous (air). Each of these phases can be considered as a continuous environment. Under such conditions, the task is reduced to consideration of the cuttings' discharge as the movement of a viscous non-contacting pseudo-liquid. Under such assumptions, the velocity field of the set of cuttings can be characterized by the Navier-Stokes equation, the solution of which will allow forming of an algorithm for building a mathematical model of the motion of such pseudo-fluid and moving to the calculation equations of the motion with initial and boundary conditions.

Published: July 2024

This article aims to analyze the term Amin in the Qur'an and its relevance to the election of the President and Vice President of the Republic of Indonesia in 2024. This is motivated by the fact that based on the campaign for the election of President and Vice President number 01, Dadang Muliawan as a volunteer campaigned by obliging the victory of Anis Baswedan-Muhaimin Iskandar and exposing his defeat. In his campaign, he strengthened his argument by mentioning a dozen verses of the Qur'an containing the term Amin. By using qualitative research methods with library research and descriptive-analytical data analysis, the results show that the verses that mention the word Amin in 14 verses in the Qur'an textually do not support that the pair Anies Baswedan and Muhaimin Iskandar are then abbreviated as "Amin". The term Amin in the Qur'an textually does not mean Anies-Muhaimin, but means a prophet or angel who has a trusted or trustworthy nature, or if it is associated with a place or city it means a safe place to live in. However, the term Amin as stated in QS. Yusuf [12]: 54 can be a basis for allowing someone to run for a certain position or campaign, as long as his motivation is for the benefit of the community and as long as he feels he has the ability and capability for that position.
