Hip and Knee Total Joint Arthroplasty Online Resources for Patients and Health Care Professionals: A Canadian Environmental Scan
Authors: Pacheco-Brousseau Lissa , Poitras Stéphane , Ben Amor Sarah , Desmeules François , Kiss Alda , Stacey Dawn
Published: March 2023

Purpose:

To appraise the quality of publicly available online Canadian resources for patients with hip or knee osteoarthritis considering total joint arthroplasty (TJA) and health care professionals participating in TJA decision-making processes.

Method:

An environmental scan. Two independent authors appraised: a) patient resources against the International Patient Decision Aids Standards (IPDAS) criteria and the Patient Education Material Evaluation Tool (PEMAT); and b) health care professional resources against six appropriateness criteria for TJA and eight elements of shared decision-making. Analysis was descriptive.

Results:

Of 84 included resources, 71 were for patients, 11 for health care professionals, and 2 for both. For patient resources, the median number of IPDAS defining criteria met was 2 of 7, median PEMAT understandability score was 83%, and median PEMAT actionability score was 60%. For health care professional resources, the median number of appropriateness criteria was 3 of 6, and the median number of shared decision-making elements was 3 of 8.

Conclusions:

Only four of 73 patient resources were structured to help patients consider their options and reach a decision based on their preferences. Health care professional resources were limited to traditional criteria for determining TJA appropriateness (evidence of osteoarthritis, use of conservative treatments) and poorly met key elements of shared decision-making.
What is the Perceived Role of the Dietitian Amongst People with Cystic Fibrosis? Results of an International survey
Authors: Anderson Hannah L. , Lynch Veronica , Moore John E. , Millar Beverley C.
Published: March 2023

Cystic fibrosis (CF) is a chronic condition requiring continued input from the CF dietitian as an integral part of the CF multidisciplinary team. In recent years, the longer life expectancy experienced by people with CF (PwCF) means that nutrition advice and therapy are evolving from a focus on nutrition support to prevention and management of comorbidities. Little has been reported regarding the perceived role of the CF dietitian amongst PwCF. We report the responses to 11 questions that were part of a larger international survey distributed to members of national CF charities in 2018-2019. These questions evaluated PwCFs’ perspectives on (i) the importance of the CF diet, (ii) how often PwCF obtain dietary/nutritional advice from their dietitian, (iii) the perceived reliability of information given by the dietitian, (iv) other sources of CF information and their perceived reliability, and (v) how CF nutrition/diet, as well as CF-related diabetes, ranked as research priorities. There were 295 respondents from 13 countries. Almost half of the respondents (46.8%) contacted their CF dietitian on a frequent/more regular basis, compared to medical/scientific journals/medical/scientific search engines. The CF dietitian was considered a reliable source of information, as 84% of the respondents indicated that the information provided was very/generally reliable. At a time when CF care and expectations are changing rapidly, PwCF are in need of trusted and reliable information to make positive changes in lifestyle and habits. Dietitians working with PwCF should appreciate the pivotal and valued role they perform as purveyors of robust evidence-based information to this chronic disease population.

Published: March 2023

Kebakaran hutan dan lahan di Riau merupakan bencana alam yang berulang setiap musim kemarau. Kondisi tanah di wilayah Riau merupakan jenis tanah gambut dengan luas total kurang lebih 4,04 juta hektar atau 56,1% dari luas lahan gambut di Sumatera, sehingga sangat rentan terhadap kebakaran. Salah satu solusi dalam penelitian ini adalah merancang sistem kebakaran dengan penerapan teknologi Internet of Things (IoT) untuk mengetahui lebih cepat tanda-tanda kebakaran hutan dan lahan. Dalam mendistribusikan data ke server, pengusul memanfaatkan cloud computing sebagai penyimpanan dan pendistribusian data. Partikel Argon (Photon) berguna untuk koneksi wifi yang kuat, selain itu juga diperlukan sensor IR Fire Detector sebagai perangkat yang mendeteksi kebakaran berteknologi tinggi dalam menentukan pola spektral yang dipancarkan oleh api. Di sisi lain, penerapan Sensor DHT22 digunakan sebagai pemantauan kualitas udara dan kelembaban dalam mengukur kualitas udara yang akan berguna pada saat kondisi udara yang disebabkan oleh kebakaran. Sedangkan untuk menentukan lokasi kebakaran hutan atau lahan, peneliti menggunakan modul GPS Neo 6m. Dalam mengukur kondisi kadar di udara diperlukan sensor MQ2, dan untuk mendeteksi kadar kelembapan air dalam tanah menggunakan Soil Moisture Sensor. Data yang dihasilkan dari detektor kebakaran yang terletak di titik kawasan hutan dan lahan akan disimpan dalam database lokal. Berdasarkan hasil penelitian yang telah dilakukan maka dapat disimpulkan bahwa alat pendeteksi kebakaran dengan menggunakan parameter api, suhu, asap, kelembaban udara, dan kelembaban tanah dapat bekerja dengan baik. Partikel Argon dapat menerima input dan membuat koneksi sehingga terhubung menggunakan konsep IoT ke web server sehingga pengguna dapat memantau kondisi lahan secara real time.

Authors: Amat Amat , Haritani Hartini , Wazni M. Khairul
Published: March 2023

This study aims to determine whether the influence of guided inquiry learning models and pro-science skills on the cognitive learning outcomes of grade V science students. This type of research is Quasi-Experimental research  with a research design using T treatment by Level 2x2. The population in this study were grade V students of elementary school. This research instrument is a multiple-choice test with a total of 20 questions. Data processing techniques and data analysis are descriptive statistics and infrencial statistics with SPSS 22. The data analysis results show significant differences in student cognitive learning outcomes with guided inquiry methods and science process skills, namely sig. = 0.000 < 0.05, meaning that there are differences in learning outcomes taught by guided inquiry (experimental class) with student learning outcomes taught by conventional approaches (control classes). Furthermore, there is an interaction caused between the use of guided inquiry methods by looking at the level of skills of the student's science process towards the cognitive learning outcomes. This can also be proven from the hypothesis test results, namely with a value of sig. = 0.000 < 0.05 means that there is a significant interaction between the use of guided inquiry and the skill level of the student's science process to influence the cognitive learning outcomes of students together. The conclusion of this study is that there is no significant interaction between science process skills and learning outcomes. The cognitive learning outcomes of students who were taught using the guided inquiry learning model were higher than those taught using the conventional learning model for students with low science process skills.

As a language skill, reading is a complex thing to master. A person's reading ability is passed through the stages of initial reading and advanced reading. Beginning reading is given to students I and II while continuing reading is given to students in grades III, IV, V, and VI. Beginning reading ability is the competency possessed by students in reciting symbols in a clear and precise voice. Therefore, beginning reading becomes something that is important for students to master before acquiring/learning advanced reading. Beginning reading mastery is strongly influenced by how the teacher is able to develop various approaches, methods and strategies used in teaching beginning reading.

What is Brand Archetype Portrait (BAPOR) and How to Calculate Brand Archetype Power (BAPOW)
Authors: DJAKELI Kakhaber , TRUE Sheb
Published: March 2023

Why to establish Brand Archetype Portrait (BAPOR) and calculate Brand Archetype Power (BAPOW)? What is the advantage of the portrait? The answer is simple - The portrait of a person shows more character than picture. When we speak about personality, it is logical to try to understand the character of a person throughportrait building than photography. We intend to extent the same principle for strategic brand management and offer a totally new method of brand portrait creation. Therefore, it is interesting to find out how the brand portrait is created.  To establish portraits of brands we need meaningful symbols. These symbols can be archetypes of Jung. They are “forms or images of a collective nature which occur practically all over the earth as constituents of myths and at the same time as individual products of unconscious origin” (Jung,1980). As we all know the unconscious was at the center of Jung's interests. Archetypes must help us in Brand Knowledge. “This brand knowledge affects how consumers respond to products, prices, communications, channels and other marketing activity -increasing or decreasing brand value in the process (Keller, 2003)”. To brand archetype portrait idea, we went through the marketing research done at KennesawState University, Coles College of Business. The purpose of the study was to find how some fast-food brands are positioned in the minds of students.  Suggesting a totally new tool - Brand Archetype Portrait (BAPOR), we believe it will be a necessary stage in the strategic brand development.

Published: March 2023

AbstractThe knowledge of the causes and effects of stress on the academic staff effectiveness  and strategies for reducing it at the university level would improve the academic standard. This will invariably have significant positive effects on all other organizations since universities mostly produce the needed high-level manpower. This study investigated the perceived stress factors on the academic staff job in state-owned universities. A proportional random sampling technique of 40% of the academic staff population was adopted to select samples across the faculties/colleges from the two state-owned universities. The instrument based on the Likert-scale and the oral interview were used to collect the data which was further analyzed using descriptive statistics and the studentT-test. The study revealed among others that academic staff was under stress because of the unconducive working environment, very high student population and inadequate physical and material resources. It was, therefore, suggested that the government should be responsive to social and economic responsibilities to achieve sustainable development.Keywords: academic, effectiveness, state-owned, stress, universitiesJEL: M12
Iran’s Gas Market after the Nuclear Deal (Characteristics and Opportunities)
Authors: AMIRAHMADIAN Bahram , BEHBOUDI NEJAD Ghodratollah
Published: March 2023

Iran owns the first largest proven gas reserves in the world. Iran's energy wealth and  geo-strategic location a bridge between East and West – allow it to export energy resources to European and Asian energy markets. However, due to various internal and international political, economic, and security constellations, Iran could not successfully exercise its energy potential internationally. The international agreement of July 2015, preconditioning lifting of sanctions and preparation of a new more competitive oil and gas contract framework in Iran signal a significant change in the international and domestic environment, allowing Iran to re-emerge in the global energy stage in a new atmosphere. Reopening Iran's energy sector will offer many new opportunities for the international oil companies. The big question is what are the Prospects and challenges for Iran’s Gas Sector? The aim of this paper is to analyze the country’s gas outlook in the aftermath of a potential nuclear deal, looking at the potential production trends, at the potential export options, but also at the political and commercial barriers that such a development will likely have to face. In fact, a full resolution of the nuclear issue will  unlikely automatically change the Iranian gas market in the short term, as a number of commercial issues will continue to remain on the table.

An Appraisal of the Perception of the Continuous Assessment Practice among Primary School Teachers in Ogun State
Authors: ADETAYO Janet Oyebola
Published: March 2023

The study sought to examine primary school teachers’ perception of the Continuous Assessment Practice in Ogun State. Four research questions were raised. The sample for the study consists of two hundred (200) teachers who were randomly selected from the four geopolitical zones in the Ogun State. The questionnaire was the only instruments used for data collection. Data collected were analyzed descriptively and inferentially using t-test of significance at 0.05 level of confidence. The result of the findings reveals that primary school teachers have high perception of continuous assessment practice. There is no significant difference between male and female teachers’ perception of the continuous assessment practice. Besides, young and old teachers significantly differ from each other while there is no significant difference between the perception of continuous assessment practices among public and private school teachers. Based on these findings, it was concluded that continuous assessment practices were poor and the implementation of continuous assessment is bedeviled with several difficulties. Therefore, recommendations were made that the ministry of education should establish a uniform standard of assessment and the system of weighting scores from different assessments should be used from school to school
Good Governance and Economic Development in Nigeria
Authors: ADEGBOYEGA Raymond Rahaj , ARIKEWUYO Kareem Abidemi
Published: March 2023

Evidence has shown that when a country’s overall governance quality and property rights system are weak, voluntary and market governance mechanisms have limited effectiveness. This may further generate economy-wide misallocation of resources and slower economic growth and make governance quality a major key factor for stable economic development which also prompted many international aid initiatives and domestic policies of developing countries to focus on improving public sector governance. This informs the need to carry out a study of this nature by examining the impact of governance quality on economic development in Nigeria. The study used the Autoregressive Distribution Lag (ARDL) method of analysis and granger causality test on secondarydata collected from World Bank data base and CBN statistical bulletin between 1982 and 2019. The results from the analysis showed that even though all the variables do not have significant impact on GR, CC and FDI_GDP exhibit a positive relationship with the GR while MC_GDP, RQ and VOA have negative relationship with GR. Also, the approximate ECM coefficient of -0.89 indicates that any deviation from the long-term equilibrium between variables is corrected by about 89% each year. Consequently, this study concludes that successful good governance mechanisms depend on good legal framework which is the bedrock for entrenching good governance measures in any country. Therefore, the study recommends among others, the need to put in place some measures of good governance quality which form the basis for promoting sound macroeconomic plans.
Main Aspects of Economic and Business Cooperation between Georgia and China
Authors: CHITADZE Nika
Published: March 2023

Bilateral relations between Georgia and Peoples Republic of China were established in 1992.China was one of the first countries who recognized independence of Georgia after the disintegration of USSR. Very soon China opened the embassy in Tbilisi, which gave a strong boost to the historical, political and economic relations between two countries.Georgia-China ties in the trade/economic relations have expanded from the period when Georgia managed to overcome the crisis,related to the Georgia-Russia war.During the last period, China has shown growing interest in Georgia. Notably, Chinese interests in Georgia currently focus on theeconomic sphere. However, the two countries share a common foundation for closer diplomatic cooperation. Additionally, deepening economic and business relations have a geopolitical corollary—by increasing its economic footprint China would have a growing interest in Georgia’s stability and security, especially, after presenting the Belt and Road Initiative (BRI) in 2013. The BRI is a diverse series of projects and encompasses both land and sea corridors and includes 65 countries - nearly two-thirds of the world’s population, and one-third of global GDP. Within this project, Georgia can help shorten the distance between China and Europe, whichwill be positively reflected on the transit potential of this South Caucasus country.

RUSSIAN FOREIGN POLICY IN AFGHANISTAN AFTER THE MILITARY COUP OF 2021. STRATEGIC STABILITY AS AN IMPERATIVE
Authors:   MGIMO University, Moscow, Russia, Petrosyan Areg
Published: March 2023

. After the military coup in Afghanistan in 2021 there was a need to look anew at the geopolitical significance of the region. In this context, there is an imperative for Russia to build mutually beneficial and stable relations with the new Kabul authorities, given the strategic importance of Afghanistan in Moscow's security architecture (mainly related to Central Asia and threat of terrorism). Besides, the opportunity emerged, against the backdrop of failed US attempts to establish peace in Afghanistan, to achieve long-term stability in Afghanistan and overall, the region through cooperation with the new Afghan government. Having achieved this, Russia will ensure the security of its allies and partners in Central Asia and minimize threats to regional security and regional interests of her.
PLACE AND ROLE OF PAKISTAN IN GLOBAL AND REGIONAL AFFAIRS

Published: March 2023

The global dynamics are rapidly changing owing to compounded, augmented and complexed security issues, assymetric conflicts, economic challenges overlapping issues of sovereignty and territorial integrities and socio-economic implications of these threats. At the core of this transitory phase lies the shift of power from the West to Asia. These realities have zoomed in the geoeconomics and the twenty first century is being drawn on this as the twentieth century belonged to the geopolitics. This fundamental transition is elevating the strategic significance of Pakistan, the "Zipper State", connecting the Eurasian Vision and a clipping state for Belt and Road Initiative. The primary factor of US to compete China and the former determining Russia a malign factor intensifies the bidding to have maximum influence in this region. India, has become a natural and potential choice of priority for the US. India's new found position in the Indo Pacific as the US Net Security Provider, it's foundational agreements with the US for huge logistic, intelligence and military systems cooperation renders it a valuable partner for the West to contain China and Russia. The emerging nexus of US-India-Israel in the Indian Ocean is clearly a bid to encircle China and Russia in which Pakistan elevates to be the front line or the first target, or if tapped and incentivized adequately, to be a defense. Russia's prudent Eurasian Vision and International North South Trade Corridor is a win-win project to engage Iran and India. Yet the former's natural inclination towards the the US and the latter's highly limited options due to Arab-Israel nexus in the Strait of Hormuz post Abraham Accords may pose a challenge to the practicality of these connectivity visions. The growing requirements of regional connectivity align China, Russia, Iran, Pakistan and Turkey naturally for the mutual and regional security and prosperity. The most significant point in this regional connectivity is the Gwadar Port having huge potential of catering to regional trade, connectivity and aligning with other regional trade routes with much better security prospects. Russia, an important global actor and regional player, and Pakistan have the suitable prospects to leverage Pakistan's magnified role in global politics for practical gains, can jointly play a better counter game.

Authors:   Institute of oriental studies, Russian academy of sciences (MOSCOW), Garin Artyom
Published: March 2023

Australia–China bilateral relations have been business oriented and pragmatic for at least 30 years. However, the period of 2019 – mid-2022 brought a more emotional political component to the interaction of the two countries. Contradictions began to accumulate between Australia and China, including those related to the vision of the future of the AsiaPacific, which subsequently turned into an urgent confrontation. Australian academic and political circles have long feared that China might take advantage of the status of the main Australia's trading partner and use the "trade punishment" measures amid growing diplomatic tensions between the two countries. The events of the past two years have made it possible to analyze these concerns in practice and determine the place of the food issue in Australia– China trade disputes. The provisions and conclusions presented in this article are based on official documents, news agency reports, as well as research by Asia-Pacific scientists.

Published: March 2023

The article examines the global market of special machinery and equipment for the mining industry. This market is characterized by a high degree of monopolization and customization. Since the beginning of the 2010s, significant transformations have been observed in this market. International corporations from developed countries producing equipment for the mining industry have increased production volumes in Asian countries. Chinese companies have managed to break in and gain a foothold in this ultra-monopolized area of production. In 2022 due to the disruption of global supply chains and the acute crisis in the countries of the collective West, the role of the China has increased even more. The article analyzes the question to what extent Russia, which is under the sanctions of the collective West, will be able to provide its economy with the necessary special machinery, what is the role of China in the Russian market of imported equipment for the mining industry.
Effect of Heterogeneity on Capillary Pressure and Relative Permeability Curves in Carbonate Reservoirs. A Case Study for Mishrif Formation in West Qurna/1 Oilfield, Iraq
Authors: AL-Dujaili Ahmed N. , Shabani Mehdi , AL-Jawad Mohammed S.
Published: March 2023

The special core analysis tests were accomplished on a set of core plugs for Mishrif Formation (mA, mB1, and mB2cde/mC units) in West Qurna/1 oilfield, southern Iraq. Oil relative permeability (Kro) data and the Corey-type fit of the data as functions of the brine saturation at the core outlet face for individual samples in the water-oil imbibition process to estimate relative permeability measurements by the centrifuge method were utilized. Identical correlations for oil and water relative permeabilities were extracted by steady-state and unsteady-state methods. For the mA samples, the gas-water capillary pressure curves were within a narrow range (almost identical) indicating that mA is a homogeneous unit. Kro curves for three mB2ab plugs were practically identical, that is referring to the homogeneity in the upper portion of the unit. The mB2 unit has a more solid‐phase concentration than other units. In addition, the general trend of low residual oil saturation is related to the raising in porosity but no reliable correlation between the residual oil saturation to water drive (Sorw) and Klinkenberg-corrected permeability (Kinf). Based on the correlation between the effective oil permeability at the initial water saturation [ko(Swi)] and (Kinf/f)1/2 for the high-permeability lithofacies mB1 plugs, ko(Swi) is approximately equal to or exceeds Kinf. While ko(Swi) was below Kinf for the other samples. New good empirical equations were obtained for effective gas permeability at final water saturation versus Kinf, as well as, for Kro and Krw versus saturation for all lithofacies.
КЛАСИФІКАЦІЯ ҐРУНТІВ ПОРУШЕНИХ НЕЗАКОННИМ ВИДОБУТКОМ БУРШТИНУ

Наведено аналіз стану вивчення питання щодо ступеня пошкодження ґрунтового покриву лісових, аграрних, водно-болотних екосистем, який міг змінюватися в межах від 5 до 80% у розрахунку на 1 га за площею та від 0,7 до 20 м за глибиною, що зумовлювало знищення родючого шару ґрунту, руйнування материнських, а подекуди і підстилаючих порід, порушення гідрологічного режиму територій, появу ерозійних процесів.За цих обставин антропогенний цикл еволюції ґрунтового покриву лісових, аграрних, водно-болотних екосистем, який супроводжувався у звичайних умовах повільним зниженням їх родючості, змінився різкою (біфуркаційною гілкою еволюції ґрунтогенезу) деградацією показників їх родючості.Для оцінки цих різних змін нами розроблена класифікація, яка побудована як бінарна система в основі якої для оцінки стану ґрунтів непошкоджених видобутком бурштину ділянок використовують систематику на основі їх номенклатури, таксономії й діагностики створеної М. М. Сибірцевим, а пошкоджених з доповненням до цієї класифікації еколого-генетичних характеристик, які відображають спрямованість деградаційних процесів у цих ґрунтах та ступінь їх проявів від слабо деградованих до сильно деградованих з можливістю за інтегрованим середньозваженим показником визначити стан непошкоджених і пошкоджених ґрунтів на площах кількісно і якісно.Встановлено, що спільною ознакою у запропонованій класифікації для ґрунтів лісових, аграрних, водно-болотних екосистем пошкоджених незаконним видобутком бурштину є встановлення кількісного і якісного оцінювання ступеня їх деградації як за площею так і глибиною.Розроблена класифікація була покладена в основу створення системи моніторингу, яка передбачає проведення контролю, оцінювання і прогноз змін стану непошкоджених і пошкоджених  ґрунтів незаконним видобутком бурштину за окремими фізико-хімічними, агрохімічними і водними так і інтегрованим середнь-озваженим показниками визначити їх ступінь деградації кількісно і якісно за шкалою: 1,0–0,68 – слабо деградовані; 0,68–0,48 – частково деградовані; 0,48–0,19 – дуже деградовані; 0,19–0 – сильно деградовані, та на підставі цих оцінок обґрунтувати управлінські рішення щодо технологій рекультивації цих ґрунтів.
ОСОБЛИВОСТІ КАСКАДНОЇ ГОДІВЛІ СТАВОВИХ РИБ НЕТРАДИЦІЙНИМИ КОРМАМИ

Published: March 2023

Вирощування риби тісно пов'язане з її годівлею, метою якої є отримання максимальної кількості продукції високої якості в найкоротші терміни за мінімальних витрат кормів. При цьому домінуючого значення набуває комерційний аспект, де прибуток є вирішальним фактором. Тому у годівлі риб триває постійний пошук шляхів здешевлення кормів і підвищення їх продуктивності, що поступово, але досить важко досягається з причини явного протиріччя цих завдань. На початку діяльності фермерських господарств у галузі рибного господарства найдоцільніше застосувати напівінтенсивний спосіб вирощування, який не передбачає занадто складних рибницьких процесів [1‒2].Технологія годівлі риби передбачає раціональне використання кормів з метою отримання високої рибопродуктивності при найменших витратах кормів на приріст маси риби. При цьому необхідно добиватись найкращої якості кормів та оптимального вмісту в них поживних речовин для забезпечення нормального перебігу фізіологічних процесів з урахуванням вікової і видової специфіки культивованих риб [2‒3].У зв'язку із збільшенням вартості штучних кормів та з метою зниження експлуатаційних затрат в сучасний період зростає необхідність використання нетрадиційних кормів – рослинного походження, продуктів переробки сільськогосподарської продукції, пасти зі смітної риби та рослинної сировини водного середовища та суходолу. Критерієм вартості та ефективності нетрадиційних кормів є наявність у них високого вмісту сирого протеїну та безазотистих екстрактивних речовин.Найвищий вміст сирого протеїну виявлений у соняшниковому шроті (42%), люпині (до 40%), у стрілолисті та різкому зниженні у зернових кормах (висівках пшениці – до 17%, висівки – до 15%, кукурудза – до 10%).Враховуючі нерівнозначність вмісту сирого протеїну у нетрадиційних кормах та динаміки маси природного живого корму за вегетаційний період необхідно їх збалансовувати, щоб отримати необхідну масу товарної риби. Для цього складається план потреби природних (нетрадиційних) кормів і штучних комбікормів (при їх співвідношенні 50:50) та план використання для кожної водойми та певної щільності посадки риб.Рекомендована щільність посадки складає від 2,0 до 4,0 тис. зарибку на гектар водного середовища.

The implementation of breeding programs for indoor vertical farms has been increasing to provide new varieties that have higher nutritional contents and morphological traits fitted to these sustainable production systems. Spinach (Spinacia oleracea L.) is one of the fastest-growing, nutrient-dense leafy vegetables to grow indoors. In Vietnam, market demand for spinach is growing together with the expansion of soilless cultivation technologies such as hydroponics and vertical farming. This research aimed to evaluate the growth parameters, initially screening the relationship between yield and biological traits, of 12 spinach varieties. In addition, this research also aimed to evaluate the lutein, vitamin C, total flavonoid, and carbohydrate contents in different varieties of spinach and their correlations with morphological traits. The research outcomes revealed significant positive correlations between plant weight and leaf area. Three spinach varieties belonging to the smooth leaf type (“AD”, “CH”, and “DT”) were the top three yielding under low light conditions. There were significant differences in the lutein content among varieties. “Red” and “Mikado” were the two highest varieties for lutein content. Vitamin C and total flavonoid contents were statistically similar in the tested varieties, while the carbohydrate content was slightly different among them. This research firstly suggested better suited spinach varieties to be grown in vertical farming conditions, and secondly, provided breeders information on trait identifications to prepare breeding materials for vertical farms

Porcine mucin 4 (MUC4) is a candidate gene for controlling the adhesion of the enterotoxigenic Escherichia coli (ETEC) F4 receptor. Polymorphisms of the MUC4 gene have been used as markers to identify the susceptibility of neonatal diarrhea in piglets for breeding selection. The objective of this study was to evaluate the effects of MUC4 g.243A>G polymorphisms on the production traits of Landrace and Yorkshire pigs in Vietnam. A total of 1,057 Landrace and 1,361 Yorkshire piglets were used to estimate the allelic and genotypic frequencies of the polymorphisms. Body weights at birth, at weaning, at initial fattening (IBW), and at the end of fattening period (FBW), backfat thickness (BFT), and depth of the longissimus dorsi muscle (DLD) were measured and lean meat percentage was estimated. Frequency of the susceptibility allele A to ETEC was higher than the resistance allele G for both breeds based on genotyping piglet tails collected at birth. The AA, AG, and GG genotypes were present in Yorkshire while GG was not found in Landrace. The production traits were not affected (P >0.05) by MUC4 polymorphisms except BFT and DLD (P <0.05). There were interactions between gender and MUC4 genotype (P <0.05) for IBW, FBW, average daily gain, and DLD. These traits of GG males were significantly higher than those of GG females (P <0.05). The results suggest that selecting pigs carrying the GG genotype of MUC4, known as providing resistance to ETEC, do not negatively affect productive performance in Landrace and Yorkshire pigs.

The soybean needs of the people in Ternate are fulfilled by imported soybeans that enter through Surabaya. The process of transporting imported soybean seeds from Surabaya to the port of Ternate and storage in warehouses may lead to contamination with Peronospora manshurica fungus, which poses a risk of spreading to soybean crops in Ternate. This study aims to detect the presence of P. manshurica fungus, viability, and growth of P. manshurica oospores in the imported soybean storage warehouses in Ternate. The study was conducted using a combination of qualitative and quantitative methods. The qualitative method was carried out through an exploratory approach, while the quantitative method used a randomized block design (RBD) consisting of four treatments, i.e., G.Tbsi, G.Jbla, G.Tfra, and G.Tfrb, with five replications. The observation variables included disease occurance, presence, and characteristics of oospores, as well as oospore growth and viability percentage. The results showed that the average disease occurance in the soybean storage warehouses was highest in the sample of soybeans from the Tfrb warehouse at 1.88%, followed by the Jbla, Tfra, and Tbsi warehouses at 1.44%, 1.41%, and 1.24%, respectively. The study also found P. manshurica fungus in all four soybean storage warehouses in Ternate, with a viability percentage of G.Tbsi, G.Jbla, G.Tfra, and G.Tfrb were 25.8%, 28.8%, 27.4%, 26.5% respectively. These findings indicate the potential for disease spread to soybean crops in Ternate, thus necessitating appropriate preventive measures to address this problem.

Sourdough bread is known to have health benefits due to its fermentation process using lactic acid and wild yeast. It can improve the taste, texture, shelf life, and nutritional content of bread as a functional food. In this study, sourdough was made from fermented papaya with varying fermentation times of 4, 5, and 6 days. The substrate was fed five times to strengthen the sourdough, resulting in a robust enough mixture to develop the dough. The resulting sourdough was used to create sourdough bread with a 30% sourdough concentration. The fermentation time impacted the quality of the sourdough, with results showing that sourdough became increasingly active as fermentation time progressed. The best sourdough was obtained from a six-day fermentation period, with a pH of 3.60 and a total plate count of 1.70 × 104 CFU/ml. The best donuts were produced using the sourdough that had been fermented for six days, with an almost perfect score of 3.9 out of 4 for all aspects, including color, aroma, taste, and texture. Using this sourdough resulted in a significantly longer shelf life; no mold appeared until the eighth day of storage at room temperature. The moisture content of the donuts was measured at 4.57%. This study demonstrates the potential benefits of using sourdough made from fermented papaya to improve the quality and shelf life of sourdough bread while also providing potential health benefits.
Individual Responsibility to Reduce Greenhouse Gas Emissions from a Kantian Deontological Perspective
Authors: Davidson Marc D.
Published: March 2023

As a collective action problem, climate change is best tackled by coordination. Most moral philosophers therefore agree on our individual responsibility as political citizens to help establish such coordination. There is disagreement, however, on our individual responsibilities as consumers to reduce emissions before such coordination is established. In this article I argue that from a Kantian deontological perspective we have a perfect duty to refrain from activities that we would not perform if appropriate coordination were established. Moral autonomy means that we do not need to wait for an external lawmaker to tell us what we ought to do. In practice, this means basing our decisions on a shadow price for carbon: if we would not go out for a drive on a sunny Sunday afternoon in a gas-guzzling sport utility vehicle if gas prices were twice as high, we should not do it now. Moreover, we have imperfect duties to reduce emissions by more than our perfect duties require.
On the Spectrum of the Non-Selfadjoint Differential Operator with an Integral Boundary Condition and Negative Weight Function

In this paper, we shall study the spectral properties of the non-selfadjoint operator in the space $L_{\varrho }^{2}\left(\mathbb{R}_{+}\right) $ generated by the Sturm-Liouville differential equation \begin{equation*} -y^{^{\prime \prime }}+q\left( x\right) y=\omega ^{2}\varrho \left( x\right) y, \quad x \in \mathbb{R}_{+} \end{equation*} with the integral type boundary condition \begin{equation*} \int \limits_{0}^{\infty }G\left( x \right) y\left( x\right) dx+ \gamma y^{\prime }\left( 0\right) -\theta y\left( 0\right) =0 \end{equation*} and the non-standard weight function \begin{equation*} \varrho \left( x\right) =-1 \end{equation*} where $\left \vert \gamma \right \vert +\left \vert \theta \right \vert \neq 0$. There are an enormous number of papers considering the positive values of $ \varrho \left( x\right) $ for both continuous and discontinuous cases. The structure of the weight function affects the analytical properties and representations of the solutions of the equation. Differently from the classical literature, we used the hyperbolic type representations of the fundamental solutions of the equation to obtain the spectrum of the operator. Moreover, the conditions for the finiteness of the eigenvalues and spectral singularities were presented. Hence, besides generalizing the recent results, Naimark's and Pavlov's conditions were adopted for the negative weight function case.
