Spatial and temporal changes in ecosystem services value and analysis of driving factors in the Yangtze River Delta Region
Authors: Zhang Wei , Wang Fang-Fang , Shan Wei
Published: March 2024

Based on land use classification data for the Yangtze River Delta region in 2000, 2015, and 2020, this study aims to explore the spatial and temporal evolution of ecosystem services value (ESV) in the region. By analyzing the land use structure and its dynamic changes, an ESV model is constructed. Furthermore, the study utilizes a geodetector to analyze the driving factors of ESV in the Yangtze River Delta region. The findings are as follows: (1) From 2000 to 2020, arable land was the predominant land use type in the Yangtze River Delta region. (2) The ESV in the region showed an upward trend followed by a decline from 2000 to 2020. Regulating services and supporting services have always been the core functions of ecosystem services in the region, with hydrological regulation contributing the most. (3) From a spatial perspective, there were significant differences in the spatial distribution of AESV (aggregated ecosystem services value) in the Yangtze River Delta region. The AESV changes in various cities within the region were evident, with a decreasing trend observed in most cities. (4) The sensitivity index of each land use type was less than 1, with forest land exhibiting the highest sensitivity and having the greatest impact on ESV. (5) Geodetector analysis revealed that the AESV in the Yangtze River Delta region is influenced by a combination of regional natural factors, economic factors, and social factors, and the interaction among different driving forces significantly enhances the spatial heterogeneity of AESV in the region.

The existence theorem, Parseval-type identity, inversion formula, and other fundamental aspects of the new integral transform are examined in this article. Integral identities define the connections between the new transforms and the established transforms. In order to solve specific initial-boundary value problems, the new transforms are used.
Security Improvement of UAV Group IoT in Polygonal Area Based on Similarity Clustering Algorithm
Authors: Yan Xiang , Xu Jia
Published: March 2024

Currently, unmanned aerial vehicle (UAV) group Internet of Things (IoT) has poor stability, poor endurance, and low security. In this regard, we report a polygon area UAV group IoT clustering algorithm for large-scale, high-speed mobile IoT environment. First, the UAV group IoT was divided into a polygon area and a few cluster heads were used to cover the polygon area uniformly. Then, the clustering index in the maximum speed similarity clustering algorithm was induced into the weighted clustering algorithm. Simultaneously, the link retention rate, relative node degree, and node residual energy ratio were improved to select the IoT node with the maximum weight as the cluster head. Finally, the IoT security was improved by reputation calculation. The results show that the clustering algorithm in this paper can reduce the number of clusters and lower the handover rate between clusters, improve the stability of clustering, prolong the survival time of the minimum node, improve the overall endurance of the IoT, and have high security.
Optimization Method Based on Machine Learning for College Students’ Psychological Control Source Propensity Classification
Authors: Wang Jing
Published: March 2024

College students tend to have more locus of control, which is greatly affected by college students, resulting in higher classification error rate and longer classification time. An optimized method for classifying the tendency of college students’ locus of control tendency based on machine learning is proposed in this article. Collect the data of college students’ locus of control tendency, build an emotional dictionary based on it, and extract the emotional words and text features from it. According to the feature extraction results, the support vector machine is used to build a base classifier to obtain the preliminary classification results. The deep belief network is used to optimize the preliminary classification results of college students’ locus of control tendency, and the final optimization results of college students’ locus of control tendency classification are obtained. The experimental results show that the error rate of college students’ locus of control tendency classification is −1∼1 %, the average recall rate is 96.2 %, and the average classification time is 0.7 s.
Contrast-Enhanced Ultrasound Features of Primary Hepatic Lymphoepithelioma-Like Carcinoma: Comparison with Hepatocellular Carcinoma
Authors: Qin Hong , Ji Zhengbiao , Zhao Qiannan , Wang Kun , Mao Feng , Han Hong , Wang Wenping
Published: March 2024

Background: Primary hepatic lymphoepithelioma-like carcinoma (LELC) is a malignant tumor with a low incidence, but the number of case reports has increased in recent years. The prognosis of hepatic LELC is better than hepatocellular carcinoma (HCC). The differentiation between hepatic LELC and HCC has clinical value during follow-up treatment. The purpose of our study was to compare contrast-enhanced ultrasound (CEUS) imaging features in patients with hepatic LELC and HCC.

Methods: Twelve patients with an average age of 60.1±9.5 years and histopathologically confirmed hepatic LELC were included in the study. Forty-three patients with an average age of 57.4±9.0 years and a histopathological diagnosis of HCC were designated as the control group by means of propensity score matching (1:4). The clinical data, B-mode ultrasound (BMUS), and CEUS features were retrospectively analyzed between patients with hepatic LELC and HCC.

Results: The serum a-fetoprotein (58.1% [25/43] vs.16.7% [2/12]; p=0.017) and des-gamma-carboxy prothrombin levels (74.4% [32/43] vs.16.7% [2/12]; p=0.001) were not significantly elevated in patients with hepatic LELCs compared to HCCs. LELCs were mainly hypoechoic based on BMUS, while the echogenicity of HCCs varied (p=0.016). A halo sign was less common in patients with hepatic LELCs than HCCs (16.7% [2/12] vs. 58.1% [25/43]; p=0.011). Of hepatic LELCs, 75% (9/12) had homogeneous hyperenhancement based on CEUS, whereas 58.1% (25/43) of HCCs had heterogeneous hyperenhancement (p=0.004). Early washout was noted in 91.7% (11/12) of hepatic LELCs compared to 46.5% (20/43) of HCCs (p=0.005). Furthermore, hepatic LELCs were more likely to exhibit peripheral rim-like hyperenhancement (83.3% [10/12] vs. 11.6% [5/43]; p < 0.001).

Conclusion: BMUS and CEUS are helpful in discriminating between hepatic LELC and HCC. A hypoechoic mass, the rare halo sign, homogeneous hyperenhancement in the arterial phase, higher frequencies of early washout, and peripheral rim-like hyperenhancement are useful ultrasound features that can help differentiate hepatic LELCs from HCCs.

Polityka językowa państwa polskiego wobec mniejszości narodowych w okresie Polski międzywojennej – wybrane aspekty
Authors: Żurek Konrad
Published: March 2024

Sytuacja prawna i polityczna mniejszości narodowych w odrodzonym państwie polskim była skomplikowana. Status mniejszości i ich prawa zapewniały postanowienia małego traktatu wersalskiego z 1919 roku. Działania mniejszości narodowych w różnym stopniu oddziaływały na państwo polskie. Odzyskanie niepodległości przez Polskę zmieniło wiele dziedzin życia. Polska w okresie międzywojennym była wielonarodowościowa i wielowyznaniowa. Państwo polskie w obliczu wielu wyzwań zmuszone zostało do prowadzenia odpowiedniej polityki językowej wobec mniejszości zamieszkujących jego terytorium. Celem tego artykułu jest ukazanie polityki prowadzonej przez państwo polskie, a zwłaszcza polityki językowej wobec mniejszości narodowych.

Published: March 2024

Świadczenie przez samodzielny i niezależny samorząd terytorialny usług publicznych, tj. usług, które powinny być w państwie dostępne dla każdego, zaspokajając potrzeby społeczne, wywołuje pytanie o zakres samorządowej samodzielności w sprawowaniu tej funkcji świadczącej, a w konsekwencji o rodzaj i zakres dopuszczalnej kontroli nad wykonywaniem przez samorząd tej funkcji w kontekście zapewnienia jednostce należytej ochrony jej publicznoprawnych uprawnień. W artykule opisano zjawisko zmiany w paradygmacie publicznoprawnego uprawnienia na przykładzie form realizacji zadań publicznych w zakresie pomocy uchodźcom z Ukrainy, a następnie rozważono wpływ, jaki ta zmiana może mieć na zakres ochrony praw jednostki, w tym w szczególności konsekwencje, jakie dla zakresu gwarancji tych praw ma będąca następstwem prywatyzacji zadań publicznych zmiana w paradygmacie sądowej kontroli administracji.
Dochody gmin z akcji banków
Authors: Gonet Wojciech
Published: March 2024

Artykuł dotyczy możliwości osiągania przez gminy zysków z akcji banków. Dokonano analizy ograniczeń w nabywaniu akcji banków, jakie wynikają z Prawa bankowego, oraz możliwości wypłaty dywidendy, którą regulują przepisy Kodeksu spółek handlowych. Wykazano, że gminy powinny ostrożnie angażować się w nabywanie znacznych pakietów akcji banków, gdyż w sytuacji konieczności szybkiego odzyskania środków finansowych ich sprzedaż będzie utrudniona przez konieczność uzyskania zgody Komisji Nadzoru Finansowego. Ponadto gminy, mimo że przepisy na to zezwalają, nie powinny tworzyć banku komunalnego, gdyż taki bank funkcjonowałby na takich samych zasadach jak inne banki, bez możliwości oferowania lepszych produktów bankowych dla gmin.

The aim of the article is to present the formation of the Citizens’ Militia as one of the institutions guarding security and public order in the period of the Polish People’s Republic. The author synthetically analyzes the “security system” of the totalitarian state, showing changes at the turn of the years in the functioning of the Citizens’ Militia, which were largely dependent on the political situation in the period of the People’s Republic of Poland. The author synthetically shows the changes in the functioning of this formation which took place at the turn of the years, and which were largely dependent on the political situation during the period of the Polish People’s Republic. The conclusion is that the MO at that time was heavily dependent on the political events that took place in the years 1944–1990 (i.e. the Thaw ‘53, June ‘56 or December ‘70).

In this paper, we study the problem of parameter estimation of the stochastic Lomax diffusion process, this process was introduced in [A. Nafidi, I. Makroz, and R. Gutiérrez Sánchez, A stochastic lomax diffusion process: Statistical inference and application, Mathematics, 2021][14], and the authors suggested the method of simulated annealing to find the maximum likelihood estimators of this process. In this work, we propose alternative methods for finding the maximum likelihood estimators, namely Genetic algorithm and Nelder-Mead, we also investigate the use of Markov Chain Monte Carlo method to determine the model parameters. Finally, an example of application through the simulation of paths for the process is suggested. Then, a comparison is made between the application of three algorithms based on their accuracy and time of execution.

Published: March 2024

The discipline of music therapy is practiced differently across the globe and over the years, in all regions of the world, the number of music therapy training programs has expanded. As such, there is a need to reflect on the differences between education and training programs, which vary according to the local culture, educational needs, theoretical background, and scope, among others. Music  therapists work in a variety of environments including hospitals, community centres, regular or special education schools, speciality clinics, private practice, and long-term care homes, etc. Music therapists are tasked with navigating policies in their workplaces and balancing the needs of their clients/consumers/service users. This article written together by educators and a student aims to present brief highlights of the work of the authors whose collaboration resulted in a presentation at the European Congress of Music Therapy in June 2022. This presentation focused on the challenges and issues faced by the discipline of music therapy and health in general, based on the analysis of systemic issues in education and training, social issues, and significant issues such as multiculturalism, equity, and race around the world. These were identified as important issues for the authors who desired to raise awareness on these topics to further open ongoing dialogue. Our aim is to contribute to the establishment of dialogues between music therapy educators, allied health professionals, researchers, and students for the implementation of new courses and the updating of existing programs, expanding views on possible music therapy interventions in contemporary times.
Workforce Characteristics, Work Satisfaction, Stress, Burnout and Happiness of Early Career Music Therapists in the United States
Authors: Meadows Anthony , Eyre Lillian , Gollenberg Audra
Published: March 2024

As part of a larger, multi-step survey, 507 early career music therapists in the United States completed a series of 26 survey questions that focused on their work lives, stress, burnout and happiness. Descriptive analysis of responses to these questions suggest the majority of these early career professionals were satisfied with their jobs and work conditions, and worked in ways they found fulfilling and meaningful. However, these data also suggest a number of challenges for early career professionals that included low salary satisfaction, high stress and burnout, and overall lower happiness than music therapists with more work experience. In particular, low levels of access to supervision and support for continuing education suggest that some early career music therapists may not be receiving the professional support they need to grow and thrive. Recommendations, along with focus areas for additional research, provide a lens through which these concerns may be addressed.

The First Blockchain: Bitcoin, Entropy, Religion
Authors: Damour Franck
Published: March 2024

Bitcoin did not suddenly appear in November 2008, at the heart of the subprime crisis. It has matured over a decade, notably through the exchanges of Nick Szabo, Hal Finney, and others, with key moments such as the publication of “The God Protocols” by Szabo in 1997. The theological analogy developed in the introduction to that text, which theorizes smart contracts, raises the question: simple facetiousness, geek irony, or a clue to religious references? By analysing not only the founding texts but also the discussions in the Extropian or cryptography mailing lists in which Szabo and Finney took part, this article seeks to answer whether religious references (vocabulary, imagination, symbolism, structure) may have played a role in the genesis of Bitcoin.
 
Empowering Diverse Faith Communities through Engagement in Participatory Science
Authors: Wolf-Chase Grace A. , Hinman Katharine E. , Trouille Laura
Published: March 2024

Developing successful strategies that promote meaningful dialogue between scientific and religious communities is arguably one of the most urgent issues of our time. Perceptions of science as hostile to religion have led governments to adopt educational policies that are not in the best interest of communities and adversely affect participation in science by people of faith, disproportionately excluding minorities and women (e.g., Bolger and Ecklund 2022; Barnes and Brownell 2018; Ecklund et al. 2019). Diversifying science requires respectfully and constructively engaging with diverse worldviews and cultures. One way this can be accomplished is through collaborative projects that facilitate building relationships across communities that might not otherwise interact.

Authors: N Machtinger Ari , S Hershey Olivia , J Bradshaw William , R McLaren Michael
Published: March 2024

This protocol details our workflow for performing concentration and total nucleic acid extraction from aggregated airplane waste for the purposes of untargeted RNA and DNA sequencing of viruses present in wastewater. Protocol overview: In this protocol, 40 mL of aggregated airplane waste is concentrated to a final volume of 400 uL using the InnovaPrep Concentrating Pipette Select. Prior to concentration, the waste sample is treated with Tween 20 and sonicated to dissociate viral particles from solids in the wastewater matrix. The waste sample is filtered using a 0.45 um PES 75 mm filtration unit, with an added pre-filter (2um glass fiber) to remove solids and bacteria. This filtrate is then concentrated with the Concentrating Pipette, using Ultra CPT tips and recommended device settings for the InnovaPrep modified wastewater processing protocol. Nucleic acids are then extracted from the concentrated product using the Zymo quick-DNA/RNA Viral kit using the manufacturer protocol with a few modifications that we have found to be helpful.
Co-extraction of RNA and DNA from animal tissue v1
Authors: Buchner Dominik
Published: March 2024

This protocol describes how to co-extract RNA and DNA from animal tissue samples. Samples are homogenized and simultaneously lyzed by bead-beating. Cell debris is pelleted by centrifugation, the DNA is then subsequently bound to a silica column, while the RNA passes the membrane. The RNA in the flow-through is then precipitated with 70% ethanol and bound to a second silica column. Both, DNA and RNA are washed with different wash buffers to remove remaining proteins and other contaminants and finally eluted in separate tubes. If the user is just interested in the RNA, the DNA spin-column can just be discarded.

In the face of challenging environmental conditions encompassing seawater exposure and dynamic wave forces, the evaluation of concrete’s durability and structural integrity in coastal structures becomes imperative. The non-destructive test using a rebound hammer device is still commonly used up to this day to assess concrete coastal structures. However, the reliability of this test is still in question since the rebound hammer still depends on the tested environment. Thus, this study aimed to appraise the reliability of the rebound hammer test in estimating the compressive strength of concrete under specific environmental conditions, namely seawater exposure and normal room conditions—utilizing a digital version of the rebound hammer. The exposure durations included one month, two months, and three months. Results showed that the average estimated strength derived from the rebound hammer test tended to overstate the actual compressive strength obtained through the direct compression test, attaining a maximum percent error of 72.7%. This suggests a notable influence of seawater exposure on rebound readings. Additionally, it was also found that concrete samples in the first, second, and third months of exposure to seawater environment had soluble chloride content values in ppm of 250, 220, and 235, and a capillary water absorption in g/(mm2*s0.5) of 0.0196, 0.0151, and 0.0149, respectively. This showed that the properties of concrete used in this study could not influence the rebound reading results. Furthermore, the overestimation raises concern about the reliability of the rebound hammer test in accurately determining the actual compressive strength of concrete.

The numerical modeling of a soil-structure interaction (SSI) system subjected to lateral loads depends mainly upon the interface behavior. The soil stiffness in relation to the structure is quite low, and the structure generally has a rough surface in contact with the soil. As a result of the slipping and rolling of soil grains caused by friction, a thin layer of shear zone forms in soil with the application of lateral loads. A thin layer interface is represented by the shear zone. As a result, the decision on the thickness requirement is critical for appropriate modeling of the thin layer interface, which is rarely documented by researchers. Furthermore, it has been reviewed in the literature that modeling the SSI system with a thin layer interface more accurately replicates the physical system than modeling it with a zero-thickness interface. The methodology for effective usage (in terms of proper interface thickness) of the thin-layer interface in SSI system using finite element (FE) modeling is proposed in this work. The thickness of the interface has also been determined via numerical modeling of a large direct shear test (DST).

There is a demand for worm gearboxes in diversified industrial fields that include machinery such as escalators, ribbon blenders, pulverisers, bowl mills, etc. because of their peculiar characteristics like torque and quick retardation. The most commonly occurring defects in a worm gear box are scratches that develop in the worm gear and in bearings. Early defect categorization is required to prevent a sudden breakdown that would decrease production. The defect is depicted in different cases, which include defects in the gear tooth and the outer and inner races of the bearing. In another case, the defect is considered in the gear tooth as well as the bearing. The severity is designated using the ANN. The experiments were performed under these conditions with a good worm gearbox to capture vibration response signatures. Using these values as an input to the ANN, the model is trained. Experimental results show that vibration amplitude increases with fault progression in the worm gearbox, and the trained ANN model effectively categorizes worm gearbox faults with an accuracy of 97.12%.

Purpose of the study. Preventive pressurised intraperitoneal aerosol chemotherapy (PIPAC) safety assessment in the combined treatment of gastric cancer (GC).

Patients and methods. The study included 48 patients with morphologically confirmed resectable GC and cardio esophageal transition, having at least one criterion that is a predictor of the development of peritoneal carcinomatosis, e. g. tumor spread to the serous layer (≥ T4a), diffuse tumor type, affected regional lymph nodes, large tumor, young age (up to 45 years), subtotally and totally affected stomach. 36 out of those patients received treatment according to the protocol. All patients received 4 cycles of neoadjuvant chemotherapy according to the FLOT scheme, radical surgical treatment in combination with a PIPAC session, 4 cycles of adjuvant chemotherapy according to the FLOT scheme. The safety assessment was carried out according to the classification of surgical complications according to Clavien-D indo and the international scale for toxicity scaling NCI–CTCAE v5.0.

Results. Postoperative complications were diagnosed in 25 %, >III grade complications were revealed in 11 % of cases according to the Clavien-D indo classification. The postoperative mortality rate was 0 %.

Conclusion. Preventive PIPAC of locally advanced GC and CET in combined treatment is a reproducible and safe method, which is characterized by the absence of an increase in the number of postoperative complications and mortality rate.

The purpose of the study. To estimate the number of patients with the preservation of relative dose intensity (RDI) ≥ 80 % of first-line antitumor therapy in patients with unresectable non-small cell lung cancer (NSCLC), and to compare the effectiveness of therapy in groups with optimal and lower RDI.

Patients and methods. The study included 30 patients (25 men and 5 women) with locally advanced unresectable NSCLC. The median age was 57 years. The main criterion for inclusion in the study was morphologically verified NSCLC with stage IIIB-IIIC of the disease. All patients underwent simultaneous chemoradiotherapy. According to the histogenesis of the tumor process, patients with a squamous cell variant prevailed.

Results. The data obtained from 22 (73.3 %) patients who retained a relative dose intensity of RDI > 80 % demonstrated that given dose intensity is sufficient to achieve a stable antitumor effect. In 8 (26.7 %) cases, however, the RDI was less than 80 %, which affected the effectiveness of the treatment. The median follow-up for overall survival (OS) was 29.2 months, progression-free survival (PFS) was 15.1 months, and local control was 21.9 months. in all patients included in the analysis. The indicators of OS in the second year had an advantage in the group of patients with RDI < 80 % and amounted to 73.3 % compared with 60.5 % in patients with RDI > 80 %. PFS was higher in the group of patients with high dose intensity, in the first year of follow-up it was 75.6 % compared with the group of patients with RDI < 80 % (62.5 %), in the second year of follow-up, PFS was 27.2 % and 20.8 %, respectively. Local control was 90.2 % in the first year in the group of patients with RDI > 80 % and 62.5 % in the group of patients with RDI < 80 %. The second year of follow-up demonstrated the advantage of the group of patients with RDI >80 % in terms of local control and amounted to 48.1 % versus 34.7 %, respectively.

Conclusion. The results obtained show that maintaining relative dose intensity at a high level has a positive effect on survival rates and local control of patients with locally advanced unresectable NSCLC. However, there is a cohort of patients who did not receive the planned amount of treatment, due to the high toxicity of simultaneous chemoradiotherapy. It is necessary to develop new approaches to concomitant therapy aimed at reducing the toxicity of the combined treatment and achieving maximum antitumor effect.

Malignant tumors of the urachus are extremely rare. The frequency of urachal malignancy makes 1: 5 000 000 cases, which is 0.35–1.2 % of all the cases of bladder cancer. The small series of observations described in the literature do not allow us to formulate statistically reliable and unambiguously recommended statements about the optimal methods of diagnostics and treatment of this pathology. The diagnosis of urachus diseases is often challenging. This is associated with both the asymptomatic course and the variety of clinical flow of the disease. The treatment strategies are also largely ambiguous and ranging from the defining the indications for surgical treatment to the aggressiveness of surgical intervention. Meanwhile, 20 % of patients with urachal cancer have distant metastases at the time of detection. With everything listed above, (low frequency, little research done and aggressiveness of the flow) it makes every clinical observation of this disease valuable.

This article is a clinical observation providing with the information upon the diagnosis, the choice of strategies and surgical treatment of urachal cancer in a patient suffering from multimorbidity. Volumetric formation of the bladder was detected in this patient during additional examination for macrohematuria. Cystoscopy with transurethral resection and subsequent morphological examination verified invasive mucinous adenocarcinoma of the bladder with the growth into the lamina propria and without the signs of vascular and perineural invasion. The patient underwent laparotomy, radical resection of the bladder with extended pelvic lymphadenectomy. The umbilicus, urachus and the bladder wall with the tumor, as well as the adjacent peritoneum, were excised as a single block during the surgical intervention. Morphological examination verified mucinous adenocarcinoma of urachus. The postoperative period was uneventful.

There have been no signs of disease progression observed during 10-month follow-up period.

In the 1980s, large parts of the Bohemian Massif in Austria were explored for the occurrence of raw materials (Göd, 1988), and a trace content of topaz was discovered in channels draining the eastern slope of the Ostrong (Lower Austria). Orthogneiss bodies in the Ostrong Nappe System are shown to be the source of these topaz occurrences, and Raman spectroscopy indicates that topaz is fluorine rich. So far, this is the only occurrence of topaz-bearing orthogneiss within the entire Moldanubian Superunit. The orthogneiss shows a tectonic overprint and exhibits a weak to well-developed foliation, as well as local folding. Samples taken near the tectonic boundary of the Ostrong to the Drosendorf Nappe Systems show stronger shear deformation with a pronounced mylonitic foliation and stretching lineation. Detailed geo-chemical investigations of the major and trace elements indicate a classification as S-type granite with a high degree of differentiation and a peraluminous character. The orthogneiss has a high SiO2 content of 72.8–77.3 wt%, as well as a noteworthy high fluorine content of up to 2760 ppm. Mineral compositions show zoned plagioclase with an albite component of about 87–99 mol%, increasing towards the grain margin. Garnet occurs rarely, but consistently in those samples near the tectonic boundary of the Ostrong- to the Drosendorf Nappe Systems. Garnet is almandine-dominated, shows no zoning and is single-phased. Sillimanite is common and samples near the tectonic boundary also contain kyanite. To determine the previously unknown protolith age of the orthogneiss, U-Pb zircon dating was applied. Three zircon fractions from two samples yield concordia ages of 475.3 ± 1.0 Ma, 474.8 ± 2.9 Ma, and 473.5 ± 1.5 Ma, identical in assigned uncertainties, reflecting magmatic zircon growth. Furthermore, the short prismatic habit of zircon grains indicates a plutonic rather than volcanic origin of the protolith. Dating results also provide a minimum sedimentation age for the rocks of the Ostrong Nappe System within Austria. In comparison with other metagranitoids and orthogneisses of the Moldanubian Nappes, the investigated orthogneiss shows strong similarities with the Gföhl Gneiss and the Moldanubian Granulite. The orthogneiss therefore is considered as a more fractionated equivalent of the Gföhl Gneiss. In conclusion we suggest to name the studied orthogneiss Laimbach Orthogneiss in the rank of a lithodeme (NACSN, 2005), after the locality Laimbach am Ostrong (48°19′01″N; 15°07′19″E), which is located centrally with respect to the occurrences of this gneiss.

The use of antibiotics in the treatment of various diseases dramatically changes the quantitative and qualitative compositions of both pathogenic and symbiotic microbiota. Oral and parenteral use of antibacterial drugs affects and changes the quantitative and qualitative compositions of the intestinal microbiota, which subsequently entails changes in the cell development and long-term violations of physiology at all levels of functioning of the macroorganism. This study analyzed available data on modern probiotic drugs, which help improve the normal microbiota in the human body. The results revealed the undoubted effectiveness of various probiotics in acute and antibiotic-associated diarrhea and eradication of Helicobacter pylori.
