Brandbekämpfung an Bord – physische Anforderungen auf verschiedenen Schiffstypen

ZUSAMMENFASSUNG Diese Pilotstudie zeigt ein kleines Spektrum möglicher Belastungen im Rahmen der Brandbekämpfung an Bord von Schiffen. Die Beanspruchungen der Probanden decken sich mit denen von Probanden, die auf Atemschutzübungsstrecken an Land untersucht worden sind. Daraus könnte man schlussfolgern, dass bei einer Eignungsuntersuchung auch vergleichbare Untersuchungsinhalte sinnvoll wären. Vorher müssten in weitergehenden Untersuchungen aber die Validität sowohl der Seediensttauglichkeitsuntersuchung als auch der Eignungsuntersuchung der Feuerwehrleute gemäß berufsgenossenschaftlichem Grundsatz durch ausreichende Evidenz nachgewiesen werden.
Does intellectual capital investment enhance firm performance? Evidence from pharmaceutical sector in China

ABSTRACT The study aims to systematically analyse the relationship between intellectual capital (IC) and firm performance measured through earnings, profitability, corporate return, sales growth, productivity, and market value. The modified Value Added Intellectual Coefficient (MVAIC) is used as a measure of IC. Multiple regression models are employed with data drawn from a sample of 204 Chinese pharmaceutical listed companies during 2013–2018. The findings suggest that the aggregate IC exerts a positive impact on firms’ earnings, profitability, corporate return, and productivity. Astonishingly, IC has a negative impact on market value and no impact on sales growth. Regarding IC components, physical capital and human capital (HC) are the main contributors to firm performance. In addition, structural capital (SC), relational capital (RC), and innovation capital are the least-developed elements of IC. Our results extend the understanding of IC in the context of China and provide some insights for management and shareholders to evaluate corporate intangible investments.

Cystic Fibrosis in Egyptian Children: Achievements and Future Directions

Cystic fibrosis (CF) is the most common potentially lethal and life-shortening genetic disease caused by mutations of the cystic fibrosis transmembrane conductance regulator (CFTR) gene. Clinical consequences of the CFTR defect are site-specific and range from severe (lungs, pancreas, male reproductive tract) to mild (intestine) to asymptomatic (sweat glands). In many developing countries CF has remained largely unrecognized, and inadequately managed, resulting in avoidable death or suffering in infancy, childhood, and adulthood. Delivering adequate CF services is met by substantial difficulties as the spectrum and distribution of CF in Egypt are still not well known. Against this background, the aim of this work is to emphasize the challenges facing initiation of a CF center in low privileged settings with the objectives of improving diagnosis, survival, and to eventually provide optimum management. Strategies for the implementation and development of CF services, as well as proper collection and documentation of patient data are therefore of vital importance. The characterization of the prevalence and molecular genetics of CF in Egypt is of utmost importance so that appropriate genetic counseling to CF patients and their families can be achieved and to pave the way for new treatment modalities. Level of Evidence of Study: IV (1).
Predictive Control of District Heating System Using Multi-Stage Nonlinear Approximation with Selective Memory

Innovative heating networks with a hybrid generation park can make an important contribution to the energy turnaround. By integrating heat from several heat generators and a high proportion of different renewable energies, they also have a high degree of flexibility. Optimizing the operation of such systems is a complex task due to the diversity of producers, the use of storage systems with stratified charging and continuous changes in system properties. Besides, it is necessary to consider conflicting economic and ecological targets. Operational optimization of district heating systems using nonlinear models is underrepresented in practice and science. Considering ecological and economic targets, the current work focuses on developing a procedure for an operational optimization, which ensures a continuous optimal operation of the heat and power generators of a local heating network. The approach presented uses machine learning methods, including Gaussian process regressions for a repeatedly updated multi-stage approximation of the nonlinear system behavior. For the formation of the approximation models, a selection algorithm is utilized to choose only essential and current process data. By using a global optimization algorithm, a multi-objective optimal setting of the controllable variables of the system can be found in feasible time. Implemented in the control system of a dynamic simulation, significant improvements of the target variables (operating costs, CO2 emissions) can be seen in comparison with a standard control system. The investigation of different scenarios illustrates the high relevance of the presented methodology.
Resistencia antimicrobiana de Salmonella spp aisladas de canales de cerdo obtenidas de dos tipos de rastros en Jalisco, México

Salmonella es una de las principales bacterias que originan enfermedades transmitidas por alimentos. El estudio de la resistencia mostrada por Salmonella a diferentes antimicrobianos ha cobrado importancia en los últimos años debido a las complicaciones en el tratamiento de las infecciones causadas por cepas resistentes. Este estudio muestra el perfil de resistencia de cepas de Salmonella aisladas en dos rastros que se diferencian en los procesos de sacrificio y faenado del ganado porcino. Los resultados de este estudio muestran que el rastro que ha implementado y cumple con los procesos sanitarios de obtención de la carne tiene una menor cantidad de aislamientos de Salmonella (1.3 %), que aquel cuyas prácticas de higiene son menos rigurosas (46.8 %) (P<0.05). Los principales serotipos de Salmonella encontrados fueron London (44.7 %), Anatum (15.8 %), Agona, Muenchen y Typhimurium (7.9 %). La resistencia a los aminoglucósidos (100 %), tetraciclinas (73.7 %) y ciprofloxacina (44.7 %) fueron predominantes en los aislamientos evaluados. El 66.6 % de las cepas evaluadas fueron resistentes a 3 ó 4 clases diferentes de antimicrobianos, y se encontró la presencia del gen que codifica para la integrasa 1. Los resultados muestran que Salmonella ha adquirido diferentes elementos genéticos que la vuelven resistente a diferentes clases de antimicrobianos, complicando el tratamiento de una infección causada por este patógeno. Así mismo, sugieren que la implementación y cumplimiento de los procesos sanitarios de obtención de la carne del ganado porcino disminuyen los aislamientos de Salmonella en las canales.
Fault Analyzer Circuit Analysis at the Load Line in Hybrid Solar/Wind System

Electric power is generated, transmitted, and distributed via large interconnected power systems. The generation of electric power takes place in a power plant. The main objective reduces the operating time of fault current removal from the load line and senses the fault current quickly to overcome its effects. The system is to be made effective and efficient while dealing with the fault situation, fault removal, and restoration of the normal operating conditions at the loading points. The results conclude the effectiveness of the proposed T-ACO-based Optimization control for the operation of the relay in accordance with the fault current limiter and analyzer circuit. The second model of the hybrid system concludes that the system having fault current limiter and analyzer circuit reduces and fault current rise and prevents the voltage from dropping to zero even if no AI-based technique is used and the operating time remains the same. The AI-based techniques further reduce the operating time also thereby making the system more efficient as the voltage is restored to its normal value in a short interval of time when the test system is simulated for 1 second in a MATLAB/SIMULINK environment.

Calcium is one of the essential materialsin the body which was found that subclinical hypo-calcemia can highly affect cows and about 47% of themultiparous with 25% of the heifers were affected. Forty animals were selected and divided into two equalgroups, first group treated with intramuscular administrations of calcium, the remained group were injectedIntramuscular normal saline. The result showed there are significant decrease in the time of parturition ingroup administered with calcium as compared with non-treated group.Aim of Study: Evaluate the role of calcium on time of parturition period and some trouble shot during it.
Morphology and Palynology Systematic Studies of The Genus Bellevalia Lapeyr. (Asparagaceae) in Kurdistan-Iraq

Morphological and palynological systematic studies for the 10 species of genus Bellivalia Lapeyr. (Asparagaceae) in Kurdistan-Iraq conducted during the growing seasons( 2015-2016) to determine the species distribution and recording new localities.The morphological investigation was dealt with the characteristics of the bulbs, stems, leaves, flowers, inflorescences, fruits and seeds and it was indicated through discussing the characters diversity that the flowers characters are taxonomically more important than vegetative characters to isolate the species. The palynological study is first conducted on Iraqi botanical specimens and indicated that pollen grains of all studied taxa of the genus Bellevalia , monads and monosolcate with variations in other characters of pollen grains which give a taxonomic importance. The species (B. macrobotrys, B. longipes, B. glauca, B. saviczii, B. olivierii, B. mosheovii, B. kurdistanica and B. pycnantha) were previously recorded and two species are new for Iraq (Bellevalia fominii and B.longistyla).
ZnSe Quantum Dots: Determination of Molar Extinction Coefficient for UV to Blue Emitters

The focus on heavy metal-free visible emitters in optoelectronic devices has increased interest in ZnSe semiconductor quantum dots (QDs) over the past decade. Empirical fit equations correlating the lowest energy electron transition to their size and molar extinction coefficients (ε) are often used to determine the concentration of suspensions containing QDs. This is essential to the design and successful synthesis of complex semiconductor nanoparticles including core/shell and dot-in-rod heterostructures as well as consistent device fabrication. While these equations are known and heavily used for CdSe, CdTe, CdS, PbS, etc., they are not well established for ZnSe nanocrystals; the only two reports of ε in the literature differ by over an order of magnitude. In this study, a series of ZnSe QDs with diameters ranging from 2 to 6 nm were characterized with small angle X-ray scattering (SAXS), transmission electron microscopy (TEM), and UV-Vis spectroscopy. SAXS-based size analysis enabled practical inclusion of small particles in the evaluation. Elemental analysis with microwave plasma atomic emission spectroscopy (MP-AES) yields a non-stoichiometric Zn:Se ratio consistent with zinc-terminated spherical ZnSe QDs. Using these combined results, molar extinction coefficients for each QD sample were calculated. Empirical fit equations correlating QD size with its lowest energy electron transition (i.e., 1S peak position) and molar extinction coefficients for both 1S peak and high energy wavelengths are reported. These results will enable the consistent and reliable use of ZnSe core particles in complex heterostructures and devices.
Management of 2–4 cm Papillary Thyroid Carcinoma: Risk of Recurrence Compared to 1–2 cm and >4 cm

Purpose: Clinicians still debate how to manage 2–4 cm papillary thyroid carcinoma (PTC). To understand the characteristics and prognosis of these tumors, we compared clinicopathological prognostic factors and prognosis among 1–2 cm, 2–4 cm, and >4 cm PTC. Methods: We retrospectively reviewed the medical records of 2,079 patients with primary PTC >1 cm who were diagnosed between 2002 and 2017. Results: The patients' mean age was 47.9±12.5 years, and 83.2% were women. The followup period was 81.1±41.8 months. The tumor recurred in 138 patients (6.6%), and thyroid cancer-related death developed in 3 cases (0.1%). As tumor size increased, so did the proportion of male patients, lymphovascular invasion, resection margin positivity, lymph node (LN) metastasis, metastasis in >5 LNs, T4, N stage, and M stage. Recurrence increased linearly according to tumor size, as did distant metastasis as first recurrence and progression to distant metastasis. Tumor size, N stage, metastasis in >5 LNs, and LN metastasis were significant independent risk factors for PTC recurrence. The recurrence rate of 2–4 cm PTC was 13.4%, while the risk of recurrence was 3 times higher than in 1–2 cm PTC. The 5-year recurrence free survival (RFS) rates of 1–2 cm, 2–4 cm, and >4 cm PTC were 97.0%, 88.0%, and 74.0%, respectively, while the 10-year RFS rates were 95.0%, 84.0%, and 71.0%. Conclusion: The 2–4 cm PTC may be pathologically distinct from 1–2 cm PTC and should be treated differently.
THE ROLE OF BETA-AMYLOID IN NORM AND AT ALZHEIMER`S DISEASE

Alzheimer’s disease (AD) is a neurodegenerative disease characterized by progressive cognitive impairment and memory loss. The pathogenesis of AD is complex, depends on many factors, and has not yet been fully studied. Extracellular deposits of amyloid-beta (Ab) peptide in the form of senile plaques, the formation of intracellular neurofibrillary tangles, and massive neuronal loss are considered as the main pathological signs of AD. However, recently there have been many data that indicate other pathways involved in the pathogenesis of AD. This review aims to analyze the existing data on the physiological role of Ab in the brain under normal conditions and its pathological role in Alzheimer’s disease.
Possibilitando o Reconhecimento de Expressões Faciais em Aplicações Ginga-NCL

As the facial recognition research field grows, so do the possibilities for digital TV applications. However, in the current state of the art, it is not safe to assume there is a certain algorithm that would be the best for all kinds of applications. This work proposes an architecture to enable facial expression recognition for TV in a way that is agnostic to the recognition algorithm. As proof of concept, the proposal was developed for the Ginga middleware. There are two implementations: the first one, based on the current version of the Ginga middleware, and the second one, based on a proposed extended version of the middleware, exploring the viability of the present work.
Evaluation of the Antibacterial and Phytochemical Activity of Ripe and Unripe Orange Peels (Citrus sinensis and Citrus aurantium)

Original Research Article Citrus fruits are rich in bioactive compounds such as vitamin C, carotenoids, flavonoids, vitamin B complex and minerals which are highly beneficial to human’s health. This study was carried out to evaluate the invitro antibacterial and phytochemical activities of ripe and unripe orange peels extract on selected microorganisms. These microorganisms include Escherichia coli, Staphylococcus aureus, Pseudomonas aeruginosa, Klebsiella pneumoniae, Streptococcus spp. , Proteus spp. and Enterobacter spp. isolated from urinary tract infections and wound swabs of patients that visited Irrua Specialist Teaching Hospital, (ISTH) Irrua, Edo State. A stock concentration of each successive orange peel extract was obtained using alcohol (95% ethanol + 5% methanol) and 100% methanol (absolute). These extracts along with positive and negative controls were tested for the presence of active phytochemicals. The result showed that the zones of inhibitions were significantly higher with methanol extract than alcohol extract against the test organisms. The zone of inhibition of all extracts against the test pathogenic organisms showed a significant increase as the concentration of the extract increased. The minimum inhibitory concentrations of the methanol and alcohol peel extracts ranged between 6.25-12.5 mg/ml while the minimum bacteriocidal concentrations ranged between 12.525mg/ml. Invitro investigations confirmed the antimicrobial potential of Citrus sinensis and Citrus aurantium peels against pathogenic bacteria. It is therefore recommended that further in vivo studies should be done to determine the exact dosage and its effectiveness in practical situations along with toxicity studies.
Level of lead contamination in the blood of Bali cattle associated with their age and geographical location

Abstract. Berata IK, Susari NNW, Sudira IW, Agustina KK. 2021. Level of lead contamination in the blood of Bali cattle associated with their age and geographical location. Biodiversitas 22: 23-29. Lead contamination is increasingly common and endangers human as well as animal health. Cattle, which is a source of protein for humans, are very sensitive to lead exposure in a polluted environment. Therefore, this study aims to determine the level of lead contamination in the blood of Bali cattle related to their geographical location and age. A total of 300 cattle was drawn as the research sample, consisting of 150 each from the low and the highland. Each comprises of 50 young ( 3 years old). The blood sample was taken from their jugular vein and collected in tubes containing ethylenediaminetetraacetic acid (EDTA) as anticoagulants. The lead content was measured using the atomic absorption spectrophotometer (AAS) method. The results showed average data for the lowlands, which include 0.430 ± 0.411 ppm, 0.792 ± 0.356 ppm, and 1.234 ± 0.533 ppm for young, puberty, and old, respectively. The highlands include 0.047 ± 0.074 ppm, 0.057 ± 0.061 ppm, and 0.089 ± 0.169 ppm for young, puberty, and old, respectively. Furthermore, the ANOVA showed a significantly higher (P<0.05) lead level in the blood of lowlands cattle than the highlands. We also found that in the lowlands, the lead level increased significantly (P<0.05) with the cattle's age, while the highlands show no difference. Based on the results, it is concluded that cattle in the lowlands are more exposed to lead than cattle in the highlands. Also, the increase in the blood lead level associated with age occurs only in cattle of the lowlands.
External axial Stress Induces Rabbit Tibia Fracture Healing via Stimulating the Expression of VEGF, CD34, BMP-2 and TGF-β1

BackgroundIt is well acknowledged that stress stimulation can promote the healing rate of fracture. However, there were few literature that described the relationship between stress stimulation at the fracture site and the molecular mechanism in fracture healing process. The aim of this study was to investigate whether external axial stress, provided by the stimulator, postoperatively, can accelerate the union of rabbit tibial fracture, and to reveal the possible mechanism.MethodsSeventy-two New Zealand rabbit tibial fracture models were established and randomly divided into two groups. Rabbits in experiment group (n=36) were subjected to external axial stress stimulation for 30 minutes every two days from the eighth day postoperative, but rabbits in control group received no stress stimulation. All rabbits were treated with external plaster for limb immobilization after operation. Lane-Sandhu X-ray evaluation system was used to evaluate the bone healing process at 2, 4, 6 and 8 weeks postoperative. Specimens were harvested for immunohistochemical test and semi quantitative analysis. They were applied to evaluate the expression of vascular endothelial growth factor (VEGF), CD34, bone morphogenetic protein-2 (BMP-2) and transforming growth factor-β1 (TGF-β1) at postoperative2,4,6and8weeks,respectively.ResultsThe mean Lane-Sandhu X-ray score of experiment group was significantly higher than control group at 4, 6 and 8 weeks (P<0.05, P<0.01 and P<0.01，respectively). More callus and better calcification were observed in the experiment group. The expression of VEGF (P<0.01, P<0.05, P<0.01, P<0.01, respectively) and BMP-2 (P<0.05, P<0.05, P<0.01, P<0.01, respectively) at each phase in the experiment group was significantly higher than the control group. The expression of CD34 (P<0.01 and P<0.01, respectively) and TGF-β1(P<0.01, P<0.01, respectively) in experimental group was higher than control group at2and4weeks.ConclusionsPostoperative external axial stress stimulation can facilitate the expression of VEGF, CD34, BMP-2 and TGF-β1, and stimulate the vascularization and ossification of the fracture site, therefore,acceleratethefractureunion.
