Impact of replacing natural food with commercial feed on the growth and survival of blue bream larvae (Ballerus ballerus) under controlled conditions
Authors: Piech Przemysław , Kujawa Roman 
Published: February 2023

Abstract
The effect of replacing natural food with commercial feed on the growth and survival of blue bream, Ballerus ballerus (L.), larvae reared under controlled conditions was investigated. Live food, brine shrimp, Artemia sp. (A), nauplii, was replaced after four (A4P17), eight (A8P13), and 12 (A12P9) days with commercial feed (P). The control groups were larvae fed nauplii (A21) or feed (P21) exclusively for throughout the experiment. The density of larvae was 40 ind. dm−3, and the rearing temperature was 25 ± 0.5°C. The highest blue bream larval growth rate in the groups fed the commercial feed tested was in group A12P9, in which larvae reached an average body weight of 56.1 mg with an average total length of 21.1 mm. These values were only slightly lower than those obtained in the A21 control sample. Final larval survival in each of the feeding groups ranged from 67% (A4P17) to 93% (A12P9). The larval lowest survival and growth parameters were recorded in control group P21, in which larvae received only commercial feed; this indicated the necessity of using natural food when rearing blue bream larvae.

Authors: Young Benjamin C. , Al Shaikhi Ali 
Published: February 2023

Abstract
Diversifying aquaculture in Saudi Arabia with the inclusion of finfish species already reared in the Mediterranean Sea requires a sufficient understanding of the preferences and limits of cultured fish under local conditions. Two trials involving European seabass, Dicentrarchus labrax (L.) juveniles of 126 g and pre-adult fish of 313 g were carried out in Saudi Arabia. The trials tested four locally available commercial feeds for 84 and 80 days to determine the growth performance of fish in local high salinity 42-45‰ conditions. The average final weight in juveniles was not significantly different among treatments. The weight gain was smaller in Diet 3, while the specific growth rate was highest in Diet 1 and smallest in Diet 3. The feed conversion ratio was similar in all diets. The average final weight in pre-adult fish showed no significant differences in final body weight, weight gain, or feed intake. The growth results appear to be in line with related research. Improvement of nutritional characteristics of the feed is expected to improve the performance of the fish.

Published: February 2023

Abstract
Numerous marine fishes from the Algerian coast were examined for nematode parasites. Our study revealed five species of nematodes that were identified according to morphological characteristics: Anisakis
simplex, Hysterothylacium aduncum, Hysterothylacium reliquens, Hysterothylacium fabri, Dichelyne pleuronectidis. D. pleuronectidis was newly collected from the study region. Four new host species were recorded for A. simplex, six for H. aduncum, and three for H. fabri. The infection rates observed were higher for Hysterothylacium and Dichelyne than Anisakis. The highest infection rate by Nematoda parasites were recorded for Trachinus draco L., Pagellus acarne (Risso) and Mullus barbatus L. (P = 100%, P = 53.33%, P = 42.5%), respectively. Nematoda larvae were found in body cavity and musculature. Histological changes associated with nematode musculature infestation revealed myodegeneration of fibers with a loss of striated texture and skin damage.

Published: February 2023

Abstract
The aim of the study was to compare the in vitro antibacterial activity of leaf extracts obtained from various Ficus species against four bacterial strains of fish pathogens (Serratia liquefaciens, Yersinia ruckeri, Pseudomonas fluorescens, Shewanella putrefaciens). In vitro tests for antibacterial activity assessment revealed that various Ficus species have notable antibacterial efficacy. The six most effective Ficus plants against S. liquefaciens that caused a zone of inhibition of at least 15 mm were F. lingua, F. erecta, F. rubiginosa, F. tinctoria, F. sur, and F. aspera. The maximum antimicrobial activity against the Y. ruckeri strain was observed for ethanolic extracts of F. hederacea, F. formosana, and F. hispida. Our results also demonstrated that the Pseudomonas fluorescens strain exhibited high susceptibility to ethanolic extracts derived from 20 plants (the mean value of inhibition zone diameters (IZD) was more than 15 mm). F. erecta, F. sur, and F. virens extracts were more effective against P. fluorescens. The Shewanella putrefaciens strain revealed a high level of susceptibility to ethanolic extracts derived from the leaves of 32 species (the highest value of the IZDs was observed for F. erecta). The data presented in the current study indicated that ethanolic extracts derived from leaves of various Ficus species are a promising alternative to the use of antibiotics and chemotherapeutics in controlling infections caused by the Serratia liquefaciens, Yersinia ruckeri, Pseudomonas fluorescens, and Shewanella putrefaciens strains.
Prime Representing Polynomial with 10 Unknowns
Authors: Pąk Karol 
Published: February 2023

Summary
In this article we formalize in Mizar [1], [2] the final step of our attempt to formally construct a prime representing polynomial with 10 variables proposed by Yuri Matiyasevich in [4].
The first part of the article includes many auxiliary lemmas related to multivariate polynomials. We start from the properties of monomials, among them their evaluation as well as the power function on polynomials to define the substitution for multivariate polynomials. For simplicity, we assume that a polynomial and substituted ones as i-th variable have the same number of variables. Then we study the number of variables that are used in given multivariate polynomials. By the used variable we mean a variable that is raised at least once to a non-zero power. We consider both adding unused variables and eliminating them.
The second part of the paper deals with the construction of the polynomial proposed by Yuri Matiyasevich. First, we introduce a diophantine polynomial over 4 variables that has roots in integers if and only if indicated variable is the square of a natural number, and another two is the square of an odd natural number. We modify the polynomial by adding two variables in such a way that the root additionally requires the divisibility of these added variables. Then we modify again the polynomial by adding two variables to also guarantee the nonnegativity condition of one of these variables. Finally, we combine the prime diophantine representation proved in [7] with the obtained polynomial constructing a prime representing polynomial with 10 variables. This work has been partially presented in [8] with the obtained polynomial constructing a prime representing polynomial with 10 variables in Theorem (85).

Published: February 2023

Summary
In this article, we formalize the theorems about orthogonal decomposition of Hilbert spaces, using the Mizar system [1], [2]. For any subspace S of a Hilbert space H, any vector can be represented by the sum of a vector in S and a vector orthogonal to S. The formalization of orthogonal complements of Hilbert spaces has been stored in the Mizar Mathematical Library [4]. We referred to [5] and [6] in the formalization.

Production Value Chain Model for Sustainable Competitive Advantage
Authors: Al-Shammari Minwir M. 
Published: February 2023

Abstract
In the Fourth Industrial Revolution, 4IR, manufacturing firms face more competitive environments, rapidly changing information and communication technologies (ICTs), and customers’ preferences than ever before. This paper analyzes relevant literature and proposes a systemic customer-centric knowledge-based production value chain (KPVC) to leverage distinctive core competencies (DCCs) and create sustainable competitive advantage (SCA) in manufacturing contexts. The paper introduces an integrative customer-centric KPVC model that enables companies to respond to environmental drivers, leverage DCCs, and create SCA. It adopts an exploratory approach to developing a unified and inherently interdisciplinary model based on a review of relevant scholarly literature. The KPVC integrated model comprises production value chain (PVC), knowledge management (KM) processes, and business process re-engineering (BPR) enabling activities. A successful move to KPVC requires a fully integrated and automated system allowing firms to define, track, and manage their work processes. Effective KPVC is a principal approach for leveraging DCCs in the quest for achieving SCA in today’s competitive business world and generating better values for customers and companies.

Published: February 2023

Abstract
The presented article deals with the use and evaluation of individual risks of work in the environment of Slovak mining company. The mining company is also a manufacturing company. The company mines the raw material and the final product (clinker). The main goal of the article is to monitor the incidence of accidents over the last 10 years, to analyse the group of risks that have a significant impact on accidents in mining companies and to evaluate them. The Risk Matrix, shows the relationship between estimated consequences and probability of risks formation. The next step is to use the workplace Risk Assessment Method to define acceptable risks and minimize the impact on workers. Another method we used is the Fault Tree Analysis (FTA) model. The output of the FTA model is the creation of a faulty tree, which resulted in the individual traumatized accidents that resulted in the definition of the resulting risk - namely a load injury.

Published: February 2023

Abstract
Recent months have highlighted the progressing energy crisis across Europe in connection with the severe sanctions imposed on the import of hydrocarbons and coal from Russia. This is particularly visible in Poland, where over 40% of electricity is generated from coal, while in individual households it is the primary source of heat. This situation puts the already enigmatic plans of shutting down coal mining in Poland into question. Therefore, work aimed at increasing the extraction capacity of existing shafts while maintaining the highest level of operational safety is still valid. This article concerns the issues of the fatigue life of compacted ropes used as hoist ropes in mine shafts. The discussion regarding the use of these ropes among shaft hoist users has been going on for several years. This paper presents the unique results of compacted rope fatigue tests carried out at the Central Mining Institute in Katowice. In the authors’ view, these results and their interpretation should serve to clarify several important aspects that arouse the interest of users.
Effect of alkali metal promoters on catalytic performance of Co-based catalysts in selective hydrogenation of aniline to cyclohexylamine
Authors: Valeš Roman , Zapletal Martin , Krupka Jiří 
Published: February 2023

Abstract
In this study, a series of Co-based catalysts with alkali metal carbonate promoters were prepared to investigate the interrelation between promotion effect of these carbonates and catalytic performance for aniline hydrogenation to cyclohexylamine in vapour phase. The chemical promoters Li2CO3 and Na2CO3 leading to decrease in catalytic activity of cobalt catalysts for aniline hydrogenation. Catalysts with K2CO3 and Cs2CO3 loadings have practically no catalytic activity for hydrogenation of aniline. Results of TPD of aniline proved that presence of alkali metals carbonates restricts the adsorption of aniline on the surface of cobalt catalysts. Further, it was found that the addition of Na2CO3 greatly enhances the catalytic selectivity towards the cyclohexylamine and inhibits the consecutive reactions of cyclohexylamine leading to formation of by-products such as dicyclohexylamine and N-phenylcyclohexylamine.

Published: February 2023

Abstract
In the paper, YSZ coatings were prepared on nickel-based alloy substrates by anodic electrophoretic deposition. The YSZ suspension solution was obtained under stirring and ultrasonic treatment, in which the anhydrous ethanol and acetylacetone were used as the dispersion medium and ammonium polyacrylate was used as the dispersant of the suspension. The effects of different deposition voltage and deposition time on YSZ coating were investigated. Meantime, the microstructure of the coating surface was observed by metallographic microscope. It was found that the high-quality YSZ coating could be obtained by deposition at 60 V for 2–3 min. Finally, the effect of sintering temperature on coating quality was investigated by X-ray diffractometer and scanning electron microscopy. The results showed that the YSZ coating bonded closely with the substrate after sintering at 1200 oC, and the porosity of the YSZ coating increased after sintering

Abstract

Introduction
The sepsis syndrome is potentially affecting several organs and systems irrespectively of the primary source of the infection. Alterations of the brain function in sepsis patients may result either from a primary central nervous system (CNS) infection or could be part of the sepsis-associated encephalopathy (SAE), a common complication of sepsis, characterized by a diffuse dysfunction of the brain due to an infection elsewhere in the body without overt CNS infection. Aim of the study was to evaluate the usefulness of electroencephalography and the biomarker neutrophil gelatinase-associated lipocalin (NGAL) when measured in the cerebrospinal fluid (CSF) in the management of these patients.

Methods
Patients presenting at the emergency department with altered mental status and signs of infection were included in this study. Among initial assessment and treatment of the patients based on the international guidelines for treating sepsis, NGAL was measured in the cerebrospinal fluid (CSF) using ELISA technique. Electroencephalography was performed when possible within 24 hours after admission and EEG abnormalities were recorded.

Results
32 of 64 patients included in this study were diagnosed with central nervous system (CNS) infection. CSF NGAL was significantly higher in patients with CNS infection compared to patients without CNS infection (18.1 [5.1–71.1] vs 3.6 [1.2–11.6]; p<0.001). There was a trend for higher CSF NGAL in patients with EEG abnormalities, which did not reach statistical significance (p=0.106). CSF NGAL levels were similar between survivors and non-survivors (medians: 7.04 vs 11.79).

Conclusion
In patients presenting at the emergency department with altered mental status and signs of infection, CSF NGAL was significantly higher in patients with CSF infection. Its role in this acute setting should be evaluated further. CSF NGAL could be suggestive of EEG abnormalities.

Abstract

Introduction
Normal saline (N/S) and Ringer’s-Lactate (L/R), are administered in everyday clinical practice. Despite that, N/S increases the risk of sodium overload and hyperchloremic metabolic acidosis. In contrast, L/R has lower sodium content, significantly less chloride and contains lactates. In this study we compare the efficacy of L/R versus N/S administration in patients with prerenal acute kidney injury (AKI) and pre-established chronic kidney disease (CKD).

Methods
In this prospective open-label study we included patients with prerenal AKI and previously known CKD stage III-V without need for dialysis. Patients with other forms of AKI, hypervolemia or hyperkalemia were excluded. Patients received either N/S or L/R intravenously at a dose of 20 ml/kg body-weight/day. We studied kidney function at discharge and at 30 days, duration of hospitalization, acid-base balance and the need for dialysis.

Results
We studied 38 patients and 20 were treated with N/S. Kidney function improvement during hospitalization and at 30 days after discharge, was similar between the two groups. Duration of hospitalization was also similar. Anion-gap improvement as expressed with Δanion-gap between discharge and admission day was higher in those patients that received L/R in comparison to those that received N/S and pH increase (ΔpH) was slightly higher in the L/R group. No patient required dialysis.

Conclusions
Administration of L/R or N/S to patients with prerenal AKI and pre-established CKD had no significant difference in short or long term kidney function but L/R showed a better profile in acid-base balance improvement and Cl− overload in comparison to N/S.

Authors: Lupoi Daniel , Milea Alex Iulian , Bejenariu Andreea Elena 
Published: February 2023

Abstract
Septal perforation is a nasal condition discovered incidentally during an ENT clinical examination. Sometimes, patients may experiment epistaxis, septal crusts at the edge of perforation, nasal obstruction, whistling, rhinorrhea or even pain.
Doctors should be familiarized with the etiology of septal perforations in order to apply the best treatment possible. This etiology includes some of the following: iatrogenic, self-injury, drugs, inflammatory diseases, etc. A very good anamnesis and clinical examination should be performed. Also, paraclinical investigations are required depending on the particular situation. Treatment should be individualized and may include conservational techniques or applying of grafts/flaps for closing the septal perforation.
In this article, some of the most frequent causes of septal perforation are reviewed, with some examples from our clinic and short reminder of steps to be taken in this case.

Published: February 2023

Abstract

BACKGROUND. Medulloblastoma is the most common central nervous system embryonal tumor in children. In adults, this tumor is extremely rare, accounting for nearly 1% of primary brain tumors. Raised intracranial pressure signs are common manifestations of posterior fossa tumors, but tinnitus and/or sensorineural hearing loss are very uncommon presenting symptoms.

MATERIAL AND METHODS. Starting from a very rare case of a 39-year-old male with left tinnitus and progressive left sensorineural hearing loss as isolated symptoms of a medulloblastoma, we performed a literature survey using the PubMed, ProQuest, Web of Science, Science Direct, Wiley Online search engines for patients with medulloblastoma and tinnitus and/or sensorineural hearing loss.

RESULTS. All patients found in the relevant literature with auditory dysfunctions presented sensorineural hearing loss. Other frequent manifestations were: ataxia, facial numbness, vertigo, headache, nystagmus. Two patients were found with tinnitus and sensorineural hearing loss as isolated symptoms of medulloblastoma, as in our case, and in two other cases the sensorineural hearing loss was the unique symptom. With refers to the onset of medulloblastoma, just 3 patients had the first symptoms sensorineural hearing loss and tinnitus.
Concerning the tumor location, in patients manifested with isolated tinnitus and sensorineural hearing loss, like our patient, the tumor arised from the internal auditory meatus, extended to the cerebellopontine angle or involved the vestibulocochlear nerve.
With regards to treatment, surgery in association with radiotherapy and chemotherapy was elected in most cases (38%).

CONCLUSION. It is important to pay attention at patients with isolated auditory dysfunction that may mimic significant posterior fossa tumors, such as a medulloblastoma.
