Psychoeducation has been used as the main anxiety management for patient diagnosed with anxiety disorder. The aim of the study to asses effectiveness of psycho- educational program among patients diagnosed with anxiety. Methodology : A quasi-experimental design was carried out on 82 patients diagnosed with anxiety disorder. The patients attended a knowledge-based psycho-educational program, and anxiety level was measured using the Zang anxiety self-rating scale in pre- post- intervention status. The data was analyzed using the statistical package for social sciences (SPSS) version (23). Results: this study has demonstrated that anxiety was high among female (67.1%) and high educated (44.9%) comparatively. The study has also indicated that psychoeducation program has significant impact on decreasing the anxiety severity. The percentage of severe anxiety in pre-intervention state was (40.2%), mild and moderate anxiety level was (9.8%) and (50%) respectively, while in post-intervention status, severe anxiety level was (20.7%), mild and moderate anxiety level were (15.9%), (63.4%) respectively. Conclusion : This study concluded that psych - education intervention could significantly reduce level of anxiety among anxiety patients. The impact of a psychiatric education program is primarily due to increased knowledge about anxiety and improved problem-solving skills for anxiety sufferers. Anxiety was observed less frequent in male, single and less educated, while anxiety was more severe comparatively.","PeriodicalId":33835,"journal":{"name":"Passer Journal","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-09-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"68882591","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Several TTS systems generate natural-like speech signals in numerous languages, such as English. On the other hand, the Kurdish language has just been examined. Existing preliminary research on Kurdish speech synthesis has utilized old methods and has generated low-quality speech. They also lack important aspects of speech, including intonation, emphasis, and rhythm. Some approaches were presented to address these challenges, including the use of concatenative systems. For example, the unit selection or statistical parametric methods. On the other hand, they need a great deal of time, effort, and domain knowledge. An additional factor for Kurdish speech synthesizers' low performance is the absence of publicly available speech corpora, unlike English, which has many freely-available corpora and audiobooks. The motivation of this paper is to create a Central Kurdish speech corpus and generate a human-like speech from the Kurdish text. This paper explains how to utilize Tacotron 2, an end-to-end neural network architecture and HiFi-GAN vocoder, to produce a high-quality, realistic, and human-like Kurdish voice. This work utilizes \"text, audio\" pairings, which contain 10 hours of recorded audio samples and texts collected from the Internet and textbooks. It shows how to use English character embedding as the pre-trained knowledge with Kurdish characters as input and how to preprocess these audio examples to get a great outcome. Our evaluations for various types of texts show a mean opinion score of 4.1, comparable with state-of-the-art synthesizers in other languages. 2022 Production by the University of Garmian.

Water productivity is not reported for most crops in Iraq and the Kurdistan Region of Iraq (KRI) where water scarcity recently forces farmers to shift from traditional farming methods including surface irrigation on bare soil to modern practices including drip irrigation and mulch. This study is the first attempt in Iraq and KRI to calculate and report water productivity for tomato ( Solanum lycopersicum ) under drip irrigation with plastic mulch at the farm scale. Data of yield production, the number of irrigation, irrigation duration, and data of cost and benefit of production were collected in 2021 from 32 farmers who produced tomato from an area of 95 ha. The yield, water use, and water productivity were then calculated. The mean values were 82.7 ton ha -1 , 31,083 m 3 ha -1 , and 2.8 kg m -3 for yield, water use, and water productivity, respectively. Hence, to produce 1 kilogram of tomato, 350 liter of water was applied. Farmers irrigate the farms each time 2-3 times longer than in previous years. Thus, this water productivity value is lower than many values reported in the literature for drip irrigation and surface irrigation even, likely due to lower rainfall amount in 2020-21 compared to the previous season. Cost-benefit analysis shows that 21% of production benefits are water use, 14% is production cost and the remaining 65% is a net benefit. Although a substantial amount of water is used, tomato production is a profitable emerging business in the area. The recent shift from surface irrigation on bare soil to drip irrigation and mulch is a successful strategy in adaptation to current water scarcity in the region.","PeriodicalId":33835,"journal":{"name":"Passer Journal","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-08-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47484048","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The impact of various zinc salts on the characteristic’s properties of synthesized ZnO NPs and which salt is more suitable for the synthesis of the ZnO NPs were investigated. The used different zinc salts were Zinc Nitrate Hexahydrate (ZNH), Zinc Acetate (ZA), and Zinc Chloride (ZC). The properties of synthesized NPs were studied using a variety of characterization techniques. The FTIR analysis and UV-Visible spectroscopy of ACW plant leaf extract proved to suggest this extract is a better choice for the green synthesis of ZnO NPs. The UV–Visible spectra of leaf extract showed two distinct absorption peaks in the region of 262 nm and 350 nm at ambient temperature. The FE-SEM analysis revealed a spherical form of ZnO NPs having an (average) mean size in the range of (21.61-63.12) nm. Also, XRD results revealed the formation of a hexagonal wurtzite structure. The crystal size of produced ZnO NPs along the (002) diffraction peak was in the range of (16.91 to 28.19) nm for different Zinc salt. The EDX analysis shows that the produced ZnO NPs are very pure. The FTIR results displayed there is no obvious peak in the monitoring range, suggesting that the ZnO NPs created via using ACW Leaf Extract. Also, the UV-Vis. results of ZnO NPs showed that the sharpness peak in exciton absorption region, and UV absorption edge were found (381-397) nm, which is corresponding to the E g of the ZnO NPs, and the investigated E g of ZnO NPs was in the range of (3.12-3.25) eV.

Shortly after that number of cases increased significantly but, limited research has been conducted to assess the knowledge, attitudes, and practices of the population in the region about the pandemic. Objectives: The objective of this study was to gain a better understanding of the people’s awareness and their attitude towards the pandemic by conducting a knowledge, attitude and practice (KAP) survey. Materials and Methods: A quantitative, descriptive, cross-sectional online survey, and non-probability, convenient sampling of 325 adults, was conducted during a complete lockdown period from (5th to 20th of April, 2020) in KRI. Results: High levels of knowledge and practice, with divided positive and negative attitudes, were found among participants. The study found a positive relationship between knowledge and attitudes and the resulting practice. Conclusions: Studies about the COVID-19 pandemic are very scarce in the KRI. There were no significance differences between the socio-demographic characteristics and levels of knowledge, attitudes and practices. We encourage further KAP studies in the KRI regarding COVID-19 for setting health awareness campaigns in promoting practical information on preventive measures to stop the spread of the virus accordingly. © 2022 Production by the University of Garmian.

Fertilized broiler eggs are imported from different countries and used by the poultry farms in the region. However, a systematic comparative study about the rate of IBV infection and maternal antibodies has not been conducted in the poultry farms of this area. Accordingly, this study was designed to compare the levels of maternal antibodies in relation to infection rates between broilers imported from different sources. From the first day until the birds reached marketing ages, eighty-five broiler farms were supervised in the Sulaymaniyah Governorate from January to December 2019. The sources of chicks were firstly recorded, and maternal antibody titers against IBV in 1–4 days old chicks were measured in 10 chicks randomly selected from each of the 85 farms. Later, the birds were observed for clinical signs relevant to infection with avian infectious bronchitis, and infections were confirmed by polymerase chain reaction (PCR). The results indicated that fertilized eggs were imported from five sources: Belgium, Bulgaria, Iran, Turkey, and the Netherlands. All chicks had maternal antibodies against IBV, with no statistically significant difference between the antibody titers (p > 0.05). However, infections occurred in 51.8% (44/85) of the farms at an average age of 22.8 days. We conclude that maternal antibodies cannot protect >10-day-old broilers, and suitable vaccination programs using local variants of the virus are necessary to eradicate IBV in Sulaymaniyah governorate, Kurdistan Region. © 2022 Production by the University of Garmian.

The model analysis is done by using finite-difference mode (FDM) solver simulation is performed by FDTD (finite-difference-time-domain). In the infrared area, this study reveals a fully unique and rigorous modal analysis waveguide. The investigation includes both primary and single-mode polarization; the waveguide is reliant on the refractive index of the layers, thickness, and substrate type. The primary novelty here for the micro-waveguide single-mode is to realize optical characteristics such as attenuation, amplitude, and full width half maximum (FWHM), which has not been done previously for specific thickness (given thickness) and for that geometrical design. Despite, we investigated how Optical waveguides are structures that confine and direct optical signals in a region of a higher effective index than its surrounding media. Our experiment (simulation) aims to investigate the single-mode waveguide of Gallium Nitride/ Aluminum Nitride GaN/ AlN on sapphire of a specified thickness in order to obtain infrared waveguide mode with minimum attenuation. Attenuation refers to any decrease in the propagated signal power that does not affect its waveform while the input wavelength is1.55μm. Additionally, describe the characterization of the mode, in keeping with our modal analysis. The waveguides have many applications in various fields such as Optical fiber communication and Photonic integrated circuits. © 2022 Production by the University of Garmian.
