Green Synthesis of Silver Nanoparticles: Synthesizing Silver Nanoparticles with L-Theanine

Silver Nanoparticles have many antibacterial uses and are becoming widely used in the medical field, industrial field, and many more industries. Creating a greener way to synthesis silver nanoparticles has been a focus within. L- Theanine, a common ingredient found in tea leaves, has been used as a reducing agent in the synthesis of silver nanoparticles. Silver Nanoparticles were obtained by mixing the following solutions, Silver nitrate, Sodium Borohydride, and L-Theanine solution. Due to the unstable silver nanoparticles formed, a stabilizer was needed. Polyvinyl alcohol (PVA) and Polyvinylpyrrolidone (PVP) were both used separately in order to stabilize the nanoparticles. With the use of Polyvinylpyrrolidone, the absorbance decreased by 8% in 40 minutes while the silver nanoparticles without PVP had a 95.9% decrease in absorbance over a 40-minute time period. In order to measure the size of the silver nanoparticles, UV- Vis absorption spectroscopy was used. Based on the UV-Vis spectroscopy, the size of the nanoparticles was around 380 to 410 nm. Silver nanoparticles made with L-Theanine have been stabilized, showing that this green method can be used to obtain silver nanoparticles

Activating Non-Place

Marc Augé defined non-place as the typical area in the urban space that has lost its identity and thus has fallen into the banal. Some of these typical nonplaces include airports, hotel rooms, convenience stores, and shopping malls. Augé argues that our urban space is ridden with these infrastructural inserts that lack of uniqueness and are homogeneous in nature. This lack of uniqueness has evolved into a mass exodus of urban interaction resulting in the identity of a city becoming lost. Auge’s nonplace are evident in our urban and suburban environments. On the other hand, Kevin Lynch defines the city as an interactive space that is composed of five categories. These five categories include paths, nodes, districts, landmarks, and edges. Lynch’s research states that elements such as the urban node are most impacted by the interaction, or junction, of people within the urban space. In the urban and suburban environments, the nodes have transformed into nonplace. This thesis is interested in exploring nonplace as a contemporary urban node and argues that with the introduction of interactive elements into generic nonplace, any urban space can be activated. Howeler + Yoon argue that the public space is now characterized by that of copresence, and less by traditional communicational and person to person interactions. Copresence is the phenomena that introduces interacting by simply being in the same vicinity with another person. Howeler + Yoon’s public space design entices individuals to interact with specific elements without requiring interaction with another person. This thesis purposes that the introduction of interactive, adaptive, and mobile elements can activate the generic, nonplace of the urban and suburban. Interactive and adaptive elements allow for individuals to interact with nonplace rather than interacting with other people if they so wish. While communication is not eliminated, these elements simply provide relief and oasis from those who look to retreat from everyday life. In addition, the urban node indicates that of intersections and connections. Therefor, this thesis also aims to explore possible systems for which a network of nodes can be created across the urban fabric

The Relationship Between Grandparent Involvement and Identity Level in Late Adolescent Females

Identity development is recognized as the key developmental task of late adolescence . The family is thought to serve as a facilitating factor in this development. Traditionally, reference to the family\u27s role in adolescent identity development has alluded to the nuclear family and to parents in particular. However, a growing consensus that nuclear families are not emotionally and psychologically isolated from extended families has permitted greater acceptance of the extended family, especially grandparents, as an integral part of the family . The purpose of this study is to examine the relationship between grandparent involvement and adolescent identity development. Identity development was measured by the Extended Objective Measure of Ego Identity Status, which is based on the four identity statuses (Achieved, Moratorium, Foreclosed, and Diffused). Grandparent involvement was measured quantitatively and qualitatively. A sample of 82 female participants in age group 18-20 was recruited from college freshmen enrolled in family and human development courses in the fall quarter 1991. The results indicate when considering grandparent involvement qualitatively, commitment within identity development appeared to be the most prevalent contributory factor while crisis (i.e., exploration) seemed to contribute when examining the quantity of the relationship. This would seem to indicate that the time adolescent grandchildren and grandparents spend together is affected to a large extent by whether the adolescent is in the process of exploring his identity while the adolescent\u27s attitude about grandparents is more affected by commitment in her sense of identity

Perceived Children\u27s Characteristics and Other Factors Relating to Parents\u27 Psychological Well-Being in Midlife

This research examined child-parent relationships from the perspective of the psychological well-being of parents during midlife and while launching children. A subsample of 1,253 parents from the National Survey of Families and Households was studied using variables from both waves (1988 and 1993) of longitudinal data. Fathers and mothers were analyzed separately for depression and self-satisfaction at the second wave (1993) in relation to their\u3c perceptions of child, adjustment and child-parent relationships in 1988, and parents\u27 employment and their marital status in 1993. Analyses showed that fathers\u27 depression scores in 1 g93 were significantly related to fathers\u27 perceptions of child adjustment (total and positive), and fathers\u27 age, marital, and employment status. Mothers\u27 depression scores were associated with their marital and employment status and with mothers\u27 perceptions of child adjustment. iii Analyses demonstrated that fathers\u27 self-satisfaction was related to all children having departed and to fathers\u27 marital status, but not to fathers\u27 perceptions of child adjustment. Mothers\u27 self-satisfaction was more frequently related to their marital status and to perceptions of child adjustment but not to children having departed. The small number of significant associations between launching and parents\u27 well-being suggests that either launching is not as highly associated with parental well-being as previously believed, or that launching is a more elusive concept than reflected by the measures used in this study. Age, employment, and marital status appear to be more salient to parents well-being than the departure of children as measured in these studies. The findings also suggest that some aspects of the role of parenting may not change significantly when children leave home. From the findings of this research, future research endeavors should reconsider the concept of launching per se as well as its relation to parents\u27 wellbeing in mid life. Other factors such as marriage and employment should be more closely studied as being more strongly related to well-being in mid life than children\u27s departures from home

The Dog Ate My Homework: A Qualitative Study of Students\u27 Views of Their Homework Experiences

Students’ voices are underrepresented in the professional literature and public conversations regarding homework; therefore, this study was designed to include students’ voices in future conversations. This study examined the responses of ten high school students enrolled in an eleventh grade English Language and Composition Advanced Placement (AP) class at a rural public school. The findings of this study answer the research questions: 1. What are students’ experiences with homework? 2. In what ways have these experiences shaped students’ views of homework? Over a period of 16 weeks, the researcher gathered qualitative data via students’ responses to essay writing, a questionnaire, open-ended questions, journal writing, focus groups sessions, and social media (Twitter) postings. At the end of the study, the findings revealed that 1. Students worry and stress over trying to divide their time between homework completion and other obligations. 2. Students struggle to complete their homework assignments because they claim they are not academically prepared. 3. Students resist homework assignments they consider unnecessary. 4. Students realize completing homework can be meaningful. The findings of this study indicate that, for different reasons and at different times, the students in this study view homework as: assignment that affect arbitrarily affects their class grades; a way to prepare for tests; assignments not worth doing; something they do not need to know or want to know; assignments they will complete it if they have to; requirements they need to fulfill; opportunities to teach them to be responsible; a way to increase their retention of subject matter; confidence building opportunities. The students in this study also offer the following adjectives to describe homework: cumbersome, stressful, tiring, confusing, difficult, unimportant, pointless, useless, boring, common sense and counterproductive. This study points to the need for education stakeholders (i.e. policy makers and elected officials, school administrators, parents, post-secondary educators, and future employers) to consider students’ perspectives of their homework experiences and include them in future conversations about homework

Nebulized Ethanol: An Old Treatment for a New Disease

Ethyl alcohol (ethanol) is known to inactivate SARS-CoV-2, and therefore, direct delivery to the upper and lower respiratory tracts hypothetically would inhibit the progression of COVID-19. After informed consent, nebulized EtOH was given to inpatients admitted with COVID-19, and outcomes were retrospectively compared to randomly selected controls. Benefits of nebulized EtOH included decreased average length of stay, improved inpatient survival, decreased intubation rate and need for transfer to intensive care, improvement in hypoxemia, and decreased need for transfer to another facility for ongoing post-acute care. Also, fewer patients required supplemental home oxygen after discharge to home. Interpretation: Nebulized EtOH is beneficial in the treatment of COVID-19. Further study is warranted

Deconstructing the LGBT-Victimization Association: The Case of Sexual Assault and Alcohol-Related Problems

Research on lesbian, gay, bisexual and/or transgender (LGBT) students has been gaining traction in the fields of criminology, victimology, and education, but available data lag behind the demand for studies on this underserved population. While LGBT students are often perceived to face greater risk of victimization and subsequent health problems than their counterparts, little research has investigated the mechanisms behind problematic outcomes for LGBT students. This research uses data from a Southeastern University to examine sexual assault among LGBT students and their experiences with alcohol-related problems. The results show that LGBT youth are at an increased risk for sexual victimization but that LGBT status does not have a direct effect on alcohol-related problems
