Opis:
This study aims at assessing and interpreting groundwater quality using statistical techniques in Otuoke and environs, Bayelsa State, Nigeria. Fourteen (14) groundwater samples were collected in the rainy season and analyzed for their physico-chemical and heavy metal contents. Heavy metals were analyzed using Atomic Adsorption Spectrometer. Assessment for drinking purposes revealed that the water is predominantly acidic, with iron and manganese contents exceeding regulatory guidelines in most locations. All other parameters were within WHO and NSDWQ regulatory limits for safe potable water. Water Quality Index revealed that over 73% of the groundwater in the area (11 samples) had good to excellent quality; while the remaining 27% of the groundwater (3 samples) have poor to unsuitable quality for consumption. Assessment of water quality for irrigation purposes was achieved using Sodium Adsorption Ratio (SAR), Potential Salinity (PS), Permeability Index (PI), Sodium percentage (Na%), Kelly’s ratio (KR), and Magnesium Adsorption Ratio (MAR). On average SAR (4.19), PI (68.51%), MAR (37.45%) and PS (0.77) revealed excellent water quality, whereas Na% (66.46%) revealed doubtful water quality while KR (2.00) revealed unsuitable water quality. Using Piper and Stiff diagrams, hydrochemical facies defined from groundwater in the area includes; Na+K – Cl facies; Na+K - Mg – Cl facies; and Na+K - Ca – Cl facies. Gibb’s diagrams revealed that the dominant control on the hydrochemical facies and overall groundwater quality in the area has been attributed to precipitation and chemical weathering of subsurface rocks. Various ionic ratios including Mg/Ca (0.642), HCO3ˉ/Cl (0.040), (Na+K)/Cl (7.026) and Cation Exchange Values (-6.026) revealed low salt inland origin with respect to provenance. Pearson correlation matrices showed both positive and negative inter-relationships between the physico-chemical and heavy metals in groundwater within the study area. This study has proven the effective use of water quality index as a tool for defining the overall quality of water in Otuoke and its environs, along with hotspots that needs immediate attention. The results could also serve as a decision making tool that will aid in establishment of treatment facilities to improve the quality of water in the study area.

Opis:
This study focused on examining the effect of vegetables extract foliar application on storage quality of the grapes grape (Vitis vinifera L. cvs. ‘Perlette’ and ‘King’s Ruby’). The vines were sprayed after fruit set twice at 15 days interval at concentrations of 0, 0.20%, 0.30% and 0.40%. Fruit were harvested and kept under cold-storage at 0.5 ±0.5°C and 90% RH for 28 days. The physicochemical properties of treated and untreated berries were analyzed at 7 days intervals during the cold storage. The results showed that the pre-harvest application of vegetable extracts reduced the weight loss and inhibited the fruit decay. Treated grape also had higher ascorbic acid contents, total phenolics, 2,2-diphenyl-1-picrylhydrazyl-radical (DPPH) scavenging activity, and higher soluble solid contents, titratable acidity, and reduced sugar:acid ratio. The concentration of 0.30% and cultivar ‘Kings Ruby’ gave the best result as compared to untreated control. In conclusion, pre-harvest vegetables extract application on berries showed higher antioxidant activities in grape berries, and maintained their post-harvest quality. These results indicated that foliar spray of vegetables extract could effectively improve the fruit quality, mainly through the reduction of phenolic content.

Opis:
A wide range of soilless cultivation techniques have been developed and introduced for intensive cropping systems and for boosting the crop yield of many vegetables, mainly in greenhouses. Adoption of some local natural by-products to be utilized as a substrate growing medium to overcome soil-related problems appeared to be a promising project. Therefore, greenhouse experiments were conducted at the Baloza Experimental Station of the Desert Research Center (DRC), North Sinai Governorate, Egypt, during the two consecutive winter growing seasons of 2016–2017 and 2017–2018. These experiments aimed to investigate the effects of seven growing substrate culture treatments of separated or mixed sand obtained from sand dunes and date palm tree residues (Karenna) on plant vegetative growth, flowering, fruit yield and quality traits, and fruit nutritional values of cucumber plants (Cucumis sativus L.) Filial-1 hybrid 1101. Crop evapotranspiration reference (ETc) and water use efficiency (WUE), as well as treatment feasibility, were also studied. The experiment was set up in a complete randomized block design with three replicates. The obtained results strongly indicated that growing substrate media containing 25% sand (S) from sand dunes mixed with 75% grinded Karenna (Kg) of date palm (1 S + 3 Kg) significantly recorded the superiority of all studied characters of plant vegetative growth, number of flowers, fruit set, yield and its components, as well as fruit N, P and K contents, compared with other growing substrate medium treatments. On the contrary, the worst values of all studied parameters were achieved when sand was used alone (100% S) as a growing media. Furthermore, the highest water use efficiency and net income values were also attained by the 1 S + 3 Kg media treatment relative to the other growing substrate medium treatments.

Opis:
Quinoa plants, originating from the Andean mountains in South America, have a large scale of biological diversity. Along with the cultivation favorableness of quinoa, it reveals superior nutrition aspects. In comparison with cereal crops, like rice, maize, and wheat, quinoa seeds contain valuable quantities of protein of remarkable quality. The current study compared four quinoa cultivars from different origins in terms of protein composition and germinability. In addition, this study focused on the effect of different geographical cultivation areas on the protein composition of wild Egyptian quinoa seeds and three other cultivars that vary in their cultivation origins. Significant differences were observed among the quinoa varieties in the germination percentage (GP), shoot length (SL), and root length (RL). Using the technology of Near-InfraRed Spectroscopy, the highest protein value was recorded for the American variety (18.39%), followed by the Wild Egyptian variety (17.16%). The aromatic phenylalanine recorded the highest concentration of the essential amino acid bulk. The Rainbow variety contained 12.7 g-aa/kg protein, followed by the wild Egyptian variety with 4.9 g-aa/kg protein. In turn, glutamic was the most abundant amino acid of the non-essential amino acids, with 10.1, 4, 23.4, and 4 (g-aa/kg protein) for quinoa varieties, Wild Egyptian, American, Rainbow, Black, respectively. SDS-PAGE was used to identify the allelic variations in the seed storage protein profiles among the studied quinoa varieties. The studied quinoa varieties showed 23.81% of the polymorphism in the protein bands, with the mean band frequency of 0.881. The resulting protein bands fluctuated in the range between 115.02 and 16 kDa. With a similarity percentage (90%), Wild Egyptian and the Rainbow quinoa varieties can be classified in one clade.

A field experiment was carried out during 2017–2018 in the Horticulture Research Station farm in El Kanater El Khayreia, El Kalubeia Governorate, Egypt, to find out the response of foliar application of melatonin, GA3 and NAA on vegetative and fruit attributes of ‘Canino’ apricot. Different plant growth regulators influenced all variable parameters related to vegetative growth and fruit. Results revealed that between all growth regulators, the foliar application of melatonin following by GA3 there was the highest vegetative growth as compared to other treatments, while GA3 gave the highest yield following by melatonin as compared to other treatments. Treatment with NAA improved vegetative growth, yield and fruit quality to a lesser extent as compared to the control.

Opis:
Black mold and green mold caused by Alternaria alternata and Penicillium digitatum, re- spectively, are the most important decay pathogens of tomato fruits during storage. Our research was aimed to control tomato phytopathogenic fungi A. alternata and P. digitatum in vitro and in vivo by using natural nanomaterials rosmarinic acid (RA-NPs) at concentra- tions of 0.3 and 0.6 mM, glycyrrhizic acid (GA-NPs) and glycyrrhizic acid ammounium salt (GAS-NPs) (0.1–0.2 mM). Characterizations of the tested nanoparticles were carried out by using dynamic light scattering which revealed that synthesized nanoparticles had particle sizes of less than 100 nm. In vitro studies revealed that the three tested nanopar- ticles reduced the growth of A. alternata and P. digitatum. Glycyrrhizic acid nanoparticles were the most effective in reducing the growth of the two tested pathogens followed by RA-NPs at 0.6 mM. Observations of A. alternata and P. digitatum by scanning electron microscopy (SEM) showed severe damage in the hyphae and deformities in the conidia due to the effect of the tested nanoparticles. In vivo results showed that, dipping tomato fruits as a post-harvest treatment in all of the tested nanoparticles at different concentrations, then stored at 10 ± 1°C and 90–95% relative humidity (RH) for 20 days greatly reduced the disease severity of infected fruits with the two tested pathogens. GA-NPs at 0.2 mM signifi- cantly reduced the development of black mold rot on tomato fruits. RA-NPs at 0.6 mM had the best effect in controlling P. digitatum of all naturally and artificially inoculated tomato fruits. Also, individual treatments of tomato fruits with RA-NPs, GA-NPs and GAS-NPs significantly reduced postharvest losses of fruit since they delayed decay and maintained fruit quality characteristics such as fruit firmness, titratable acidity and total soluble solids during cold storage.

Opis:
This paper presents the design and analysis of a polygon connected autotransformer based 36-phase AC-DC converter which supplies direct torque controlled induction motor drives (DTCIMD’s) in order to have better power quality conditions at the point of common coupling. The proposed converter output voltage is accomplished via two paralleled eighteen-pulse AC-DC converters each of them consisting of nine-phase diode bridge rectifier. An autotransformer is designed to supply the rectifier. The design procedure of magnetics is in a way such that makes it suitable for retrofit applications where a six-pulse diode bridge rectifier is being utilized. The proposed structure improves power quality criteria at ac mains and makes them consistent with the IEEE-519 standard requirements for varying loads. Furthermore, near unity power factor is obtained for a wide range of DTCIMD operation. A comparison is made between 6-pulse and proposed converters from view point of power quality indices. Results show that input current total harmonic distortion (THD) is less than 4% for the proposed topology at variable loads. A laboratory prototype of the proposed Polygon-Connected autotransformer-based 36-pulse AC-DC converter is developed and test results are presented to validate the developed design procedure and the simulation models of this AC-DC converter under varying loads.

Design of a delta/polygon-connected autotransformer based 36-pulse ac-dc converter is presented in this paper. The 36-pulse topology is obtained via two paralleled eighteen-pulse ac-dc converters each of them consisting of a nine-phase (nine-leg) diode bridge rectifier. For independent operation of paralleled diode-bridge rectifiers, two interphase transformers (IPT) is designed and implemented. A transformer is designed to supply the rectifier. The design procedure of magnetics is in a way such that makes it suitable for retrofit applications where a six-pulse diode bridge rectifier is being utilized. The proposed structure has been implemented and simulated using Matlab/Simulink software under different load conditions. Simulation results confirmed the significant improvement of the power quality indices (consistent with the IEEE-519 standard requirements) at the point of common coupling.

Opis:
Nowadays, the advancement and increased use of fifth-generation (5G) and sixth-generation (6G) systems have created a demand for more efficient and rapid transmission of information over wireless communication media. However, developing wireless communication systems that can meet these modern-day criteria for fast, reliable, and secure information exchange is a challenging task. To address this issue, this paper proposes a novel model for enhancing the 5G system. The proposed model utilizes polar code with rate matching and constitutional interleaving over the Suzuki fading channel. The combination of polar codes with rate matching and interleaving enables the communication system to achieve a lower error rate and better reliability over a Suzuki fading channel. Specifically, the polar code can correct a larger number of errors, while rate matching and interleaving can mitigate the effects of channel variations and reduce the probability of error bursts. These enhancements can lead to more robust and reliable communication in wireless networks.

Quality measurement is the first step in improving overall quality. Servqual has been identified as one of the most important methods frequently used in assessing the quality of healthcare services. This study aims to systematically review and conduct meta- analysis of conducted studies in this regard in which Servqual tools were used to assess and measure the quality of services. In this systematic review and meta-analysis, the required data were collected using several keywords (and their Persian equivalents): services quality, Servqual, quality, gap, primary health cares, health services, Iran. The databases searched were as follows: PubMed, Scopus, Google Scholar, SID, Magiran, and Iranmedex. The comprehensive meta-analysis (CMA) software, Version 2 was used for data analysis. Based on the random effect model, the total mean score of Service Consumers’ perception, Service Consumers’ expectation and the gap between them were estimated as being 3.81 (95% CI: 3.56–4.06), 4.49 (95% CI: 4.31–4.67) and -0.83 (95% CI: -065 – -1.01), respectively. The lowest score of consumers’ perception of services quality, was related to the empathy dimension (3.57) and the highest score of consumers’ expectation of services quality was related to the reliability dimension (4.60). Furthermore, there was a quality gap in all dimensions. In order to achieve desired quality and meet service receivers’ needs, attention should be always given to their views, so that proper planning can be done to address existing problems through assessing views. Should such be undertaken, we would be able to witness services quality improvement.

Monthly reports from June 2017 to May 2018 of Twenty-one wastewater treatment plants in Sharkia were evaluated for the following parameters: temperature, pH, total dissolved solids (TDS), total suspended solids (TSS), chemical oxygen demand (COD), biochemical oxygen demand (BOD), nitrate (NO3), oil and grease (O&G) and Dissolved Oxygen (DO) values. The first aim of this study was to estimate the main wastewater per capita pollution generation per day (PCPL) and found that the 90th percentile PCPL for TSS, COD, BOD, NO3 and O&G were equal to 57.42, 91.59, 59.13, 1.64 and 12.39 (g/capita/day) respectively. The second aim was to assess the performance of the WWTPs in the governorate, by calculating of the wastewater quality index (WWQI) of each plant and for the entire governorate which shows that; 2 WWTPs gives a good performance, 9 WWTPs gives a fair performance, 9 WWTPs gives a marginal performance and 1 WWTP is in bad conditions, the average performance all over the governorate is considered marginal. A simple empirical formula had been established to be used for calculation of the WWQI based on the tested parameters using the multiple linear regression and found to be very effective in predicting the WWQI for the WWTPs.

Opis:
The author of the paper presents the argument that the widespread implementation of a new healthcare service called “independent nursing consultation” will not only improve the functioning of the healthcare system, but also enhance the quality of medical services. Implementing this new service requires modifying the traditional way of organizing healthcare, which assumes that the involvement of a doctor is necessary in every case, limiting the possibilities of promptly initiating and managing treatment. By advocating the broad implementation of nursing consultations, the author first reviews the training of nurses in Poland and two other countries. Then she attempts to identify the areas of healthcare where providing nursing consultations is highly justified and beneficial. The procedure for independent nursing consultations is illustrated through the example of the activity of a large medical company, such as LUX MED Medical Center. The methods of ensuring the appropriate quality of the provided nursing consultations – by the exemplary institution – are also described. The paper justifies why the extensive introduction of nursing consultations will increase access to healthcare services, improve their quality, and have a positive impact on the size and development of the nursing workforce.
Autorka pracy przedstawia argumentację, iż rozpowszechnienie nowej usługi zdrowotnej, jaką jest „samodzielna konsultacja pielęgniarska”, przyczyni się nie tylko do usprawnienia funkcjonowania systemu służby zdrowia, lecz także poprawi jakość usług medycznych. Wdrażanie tej usługi wymaga zmodyfikowania tradycyjnego sposobu organizowania służby zdrowia, który zakłada, że rozpoczęcie leczenia wymaga w każdym przypadku udziału lekarza, co ogranicza możliwości szybkiego podejmowania leczenia i jego prowadzenia. Autorka, postulując szerokie wdrażanie konsultacji pielęgniarskich, dokonuje najpierw przeglądu metod kształcenia pielęgniarek w Polsce oraz dwóch innych krajach. Stara się następnie wskazać te obszary opieki zdrowotnej, w których udzielanie konsultacji pielęgniarskiej jest wysoce uzasadnione i użyteczne. Procedura samodzielnych konsultacji pielęgniarskich jest tu przedstawiona na przykładzie działalności dużej firmy medycznej, jaką jest Centrum Medyczne LUX MED Sp. z o.o. Opisano także sposoby zapewniania – przez przykładową instytucję – właściwej jakości udzielanych konsultacji pielęgniarskich.

Opis:
Konsument dąży do tego by posiadać coraz więcej, poprzez wydatkowanie dochodu pozyskanego z różnych źródeł. Ten chce mieć więcej, niż mniej. Przedsiębiorstwa, chcąc sprostać oczekiwaniom klienta, produkują dobra, od jakości których zależy przyszły wynik finansowy przedsiębiorstwa. Klient, nabywając dobra od producenta oczekuje możliwie najwyższej jakości produktów, przy założeniu przeciętnego pułapu cenowego, dopasowanego względem jego preferencji oraz możliwości finansowych. Zdarzyć się może sytuacja, kiedy klient nie będzie zadowolony z usługi bądź produktu. Zdarzenie to wywołuje niekorzystny efekt na przedsiębiorstwo. Celem optymalizacji tego zjawiska niezbędne jest podjęcie działań zapobiegawczych, które prawie zawsze poprzedzone są wnikliwym badaniem i analizą. W poniższym artykule przedstawione będą wybrane przez autora metody pozyskania informacji o stopniu zadowolenia (satysfakcji) klienta z nabytych przez niego dóbr. Przytoczone zostaną argumenty społeczne oraz psychologiczne, mające wpływ na końcowy poziom satysfakcji klienta. Wskazane zostaną również skutki dla przedsiębiorstwa, związane z wynikami badania stopnia satysfakcji klienta.
The consumer strives to own more and more by spending income obtained from various sources. This one wants more than less. Enterprises, wanting to meet the client's expectations, produce goods which determine the quality of the company's future financial results. When purchasing goods from a manufacturer, the customer expects the highest possible quality products, assuming an average price level, adjusted to his preferences and financial possibilities. There may be times when the customer is not satisfied with the service or product. This event has an adverse effect on the company. In order to optimize this phenomenon, it is necessary to take preventive measures, which are almost always preceded by thorough research and analysis. The following article will present the methods of obtaining information on the degree of customer satisfaction with the goods purchased by the author, selected by the author. Social and psychological arguments that affect the final level of customer satisfaction will be presented. The consequences for the enterprise, related to the results of the customer satisfaction survey, will also be indicated.
