Title: Gender Analysis of Entrepreneurial Intention among Students in Iranian Higher Education system

Abstract:The main purpose of this study was to investigate gender differences as for predictors of entrepreneurial intention among students in Iranian higher entrepreneurship education system. A survey of all students in entrepreneurship faculty of Tehran University was carried out (N = 211). 136 students were selected for the study using a stratified random sampling method. The result showed there were a significant positive relationship between entrepreneurial intentions of male students and their attitudes towards entrepreneurship, social norms and self-efficacy beliefs. While among the female students, attitudes towards entrepreneurship and self-belief had a significant positive relationship with entrepreneurial intentions. The results of the analysis showed students \'self-efficacy beliefs in male and female students\' attitudes toward entrepreneurship had the most direct and significant impact on their entrepreneurial intentions. Also, comparing the results suggested significant impact of gender on attitudes towards entrepreneurship; social norms and self-efficacy beliefs of students. The results of this study can have implications for higher education planners dealing with entrepreneurship to enhance students\' entrepreneurial intentions and behavior and reduce the gender gap in their entrepreneurial activities in the future.

Title: Bitumen Seepage: Impact and Interactions on Heavy Metal Concentrations in Surface Water

Abstract:The association and interaction among metals in bitumen polluted water may affect the availability of the metals even at toxic levels to the surrounding environment and biota that are dependent on such water. The study was carried out at Ode-Irele in Ondo State bitumen belt, Southwest of Nigeria, where there are bitumen seepages, and Ebute-Irele where there are no records of seepages served as control. Composite samples of surface water were collected to a depth of 30cm midstream on the sites. Heavy metals � Manganese, Iron, copper, zinc, lead, chromium, cadmium, nickel, vanadium, arsenic, calcium, magnesium, potassium, and sodium were determined using standard methods. Data on metals� concentrations were analyzed using descriptive statistics and t-test at p < 0.05. The associations that exist among metals of surface water were analysed using regressive correlation to determine which metal increased or decreased with rise and fall in the level of other metals. Values obtained were compared with Federal Environmental Protection (FEPA) and World Health Organisation (WHO) Guidelines. Results of the study revealed that nickel, calcium, magnesium, and sodium were higher in seepage site than that of control, but, nickel was significantly higher in surface water of seepage site, 0.40 � 0.00mg/L than that of control, 0.30 � 0.00mg/L. Manganese, iron, copper, zinc, chromium, cadmium, nickel, vanadium, and arsenic, as well as calcium were higher than guideline levels. Nickel, iron, manganese, vanadium, calcium and sodium which are elemental components of bitumen could pose serious environmental problems. There were significant positive associations between iron and copper, manganese and vanadium, iron and sodium, calcium and magnesium, as well as between magnesium and sodium. The finding also revealed significant negative association between lead and zinc. The heavy metals in surface water that were higher in seepage site and higher than guideline values in Ondo State bitumen belt and especially those that are elemental components of bitumen could have toxic effects on the environment, and so they should be closely monitored during the bitumen development phase.

Title: Management of hazard COVID-19 waste and trends for used the gamma irradiation disinfection

Abstract:The global 2019 coronavirus disease (COVID-19) pandemic has spread over The whole planet within months. Social and economic life in many countries is badly disrupted as a result of this major epidemic. As well as the environmental risk is rise Because of personal protective equipment (PPE) such as the Medical Face Safety Masks (MFSM). As well as, careful hand washing and physical space between personals and to avoid transmission of COVID-19, the wearing of medical face masks is advised. [1]. Under conditions of extreme lack of availability of surgical masks, for the general population the only use of clothes masks is recommended [2]. Both patients and healthcare personnel wear disposable surgical face masks to reduce the incidence of coronaviruses [3]. Coronaviruses diseases result in a rise in medical care costs. The consistency of surgical face masks is therefore important and is defined by the regular testing mechanism established by standards such as ASTM and European standards. With a durability of over 50 cycles, disposable surgical masks may be sterilized and washed for reuse. [4]. However, reuse surgical masks have much less safety quality relative to new mask. [4]. If the frequency of washing cycles is increased, the quality of safety for recycled ones is diminished. Repeated washing of recycled medical face masks will also use more resources and supply the environment with more polluted water. Polypropylene is used as the raw material for medical face safety masks production [5]. It has several advances such as water and moisture barrier, can produced in fabric form so it breathable and flexible beside is lightweight and non-toxic. Polypropylene is used to a non-woven fabrics and fishing nets manufacture due to is can float in the surface of seawater [6]. Conservationists since discovering disposable masks floating like jellyfish. Dynamics of waste generation and hence special attention has been needed. The unforeseen variations in the composition and quantity of waste often require policymakers to react dynamically. During an epidemic of COVID-19, several kinds of medical and toxic materials are created, including contaminated masks for faces , gloves for hand and other safety clothing, along with a higher amount of infected products of the patients food baggage. There has been a high increase in demand for goggles , gloves, hand sanitizers, and other important items since the news of human coronavirus transmission reached the press. A need of 89 million surgical masks and 76 million hand gloves for the COVID-19 produced every month was calculated by the WHO modelling, although international demand for eye protector is 1.6 million per month [7]. This research highlights the problems encountered since the pandemic by the solid waste management industry and the underlying possibility of filling current loopholes in the system. Due to increasing hygiene issues , especially for items used for personal safety and medical purposes, single-use plastic item is expected to bounce back. Leading to enhanced conscious purchasing of high non-perishable goods during lockdown and attributable to food scarcity issues, household food waste production is anticipated to decrease. The report also suggests several key guidelines for policymakers to better holistically manage potential future pandemics, if any.

Title: Inhibition Effect of Posidonia Oceanic Leaves Ethanolic Extract based on Polyvinylpyrrolidone on Mild Steel Corrosion in 1M HCl Solution

Abstract:As a cheap and effective corrosion inhibition of mild steel in 1 M HCl, ethanol extract of Posidonia oceanic leaves based on Polyvinylpyrrolidone is used using weight reduction, open circuit potential and potentiodynamic polarization methods. The results explained that the productivity of hindrance increments as the concentration of extract increases, which at 1000 ppm discovered greatest restraint efficiency ~ 81 percent. The FTIR investigation of ethanolic extract confirmed the creation of kaolin-traced phenolic and polysaccharide compounds responsible for adsorption on the surface of mild steel. Using SEM study to inhibitive action against steel in corrosive arrangement, the surface morphology was considered. It is presumed that ethanol removes from Posidonia oceanic leaves can fill in as compelling gentle steel consumption inhibitors in hydrochloric acid.

Title: Correlation between Airborne Dust and the Coronavirus prevalence: An overview

Abstract:In light of the current pandemic, the Corona pandemic, researchers are making a great effort to try to understand and appreciate the characteristics of the SARS-CoV-2 epidemic in order to reach some solutions that may lead to eliminating the disease or preventing its spread. Beginning and as mentioned by the World Health Organization (WHO), one of the most important causes of the spread of SARS-CoV-2 virus are respiratory droplets or close contact inside closed doors where the infection is transmitted through aerosols or by close contact. From our vision after see the regions of coronaviruses spread in whole world map and link it with the weather of the countries in the world maps. It was founded that the virus is increasing in many regions and countries that have achieved clear success in combating environmental pollution or that are not exposed to dusty storm, and infections are increasing again in the same country with different densities of sick people according to the weather temperature and windy season. The relationship between coronaviruses spread and dust storm is reversible this due to the dust is almost contain 90 % of metal oxide that act as nature photocatalysts for O●-2 and ●OH production. This oxidizing spices are capable to destroy SARS-Cov-2.

Title: Improvement of TiO2 photocatalytic activity under visible light for removal of congo-red dye by co-doping N-C atoms from chicken egg white

Abstract:The present work is focused on co-doping TiO2 with N and C atoms from chicken egg white in order to enhance its activity under visible light for removal of congo-red dye from water through photodegradation. The co-doping TiO2 was prepared by interacting TiO2 suspended in water with chicken egg white with various weight through hydrothermal technique in an autoclave. The co-doped TiO2 photocatalysts were characterized by FTIR, XRD, DRUV, TEM, and SEM-EDX instruments. The photocatalytic activity is evaluated for degradation of congo-red dye in water through batch experiment. The characterization data assigned that doping TiO2 with C and N atoms from protein of chicken egg white has noticeably narrowed the gap, that shifted the absorption into visible region. The narrowing gap indicated by declining band gap energy (Eg), was found to be influenced by the weight of the chicken egg white for a constant TiO2 weigh, and the most significant decrease of the Eg, that was 2.70 eV from 3.2 eV, was shown by TiO2/N-C with ratio weight of TiO2 : chicken egg = 1:2. The co-doping TiO2 has considerably enhanced the photodegradation of congo-red dye in water under visible light, compared to the un-doped one. The highest photodegradation of 10 mg/L congo-red dye was reached by TiO2/N-C with 1:2 ratio, in 45 min of time, at pH 7, and 50 mg photocatalyts/100 mL solution. that was about 98% under visible light, while over undoped TiO2 was found to be 60%.

Title: Development and Evaluation of Human-Water Harmony Index

Abstract:In the present study, Human-Water Harmony Index (HWHI) was developed to evaluate the human-water relationship. HWHI model considers 22 basic indicators from three dimensions, water system (WS), human system (HS) and human water coordination system (CS). The developed model was then applied for the evaluation of human-water harmony status in five fast-developing cities, that are three in Pakistan - Karachi, Lahore, Faisalabad, and two in China - Nanjing and Zhang-YE. The result showed that the selected cities are confronting with human-water harmony challenges of varying degrees in different dimensions. Nanjing provides the best harmony status between human and water followed by Lahore, Zhang-Ye, Faisalabad and Karachi. The HWHI model provides the weaknesses and strengths of cities in specific sectors. Therefore, the development of HWHI will be helpful for the decision makers to devise strategies and policies to build the harmonious human-water harmony relationship. The approach presented in this study can be applied in other cities or regions round the World to evolve improved water management strategies for future sustainable development.

Title: Do ethics and morals really represent the best possible blueprints for the good life? Reflections on a possible pedagogy of discernment

Abstract:Making use of hermeneutic phenomenology and morality critique as methodological navigation points, this paper challenges the illusory prestige and power of normative orders in presenting themselves to every successive generation as the best possible likenesses of and most believable blueprint(s) for eudaimonia (the good life). By implication, it also challenges the education systems that are designed to keep these normative orders alive. It is suggested that what education needs is not morals and ethics, but a pedagogy of discernment that will teach pupils to keep their eyes open and to recognise the tragic truth that normative systems maintain themselves at the cost of wiping out the ontic truth of singularisation, mortality, as well as the ultimate non-normalisability of the human condition, namely that although we are capable of immense love and sensitivity, we are also capable of greed, hatred, brutality, rape, murder and war.
