Detergent Less Ultrasound-Assisted Extraction Of Trace Elements From Edible Oils Using Lipase As An Extractant, Derya Kara, Andrew Fisher, Steve Hill

School of Geography, Earth and Environmental Sciences

A new method for the extraction and preconcentration of trace elements (Al, Ba, Cd, Cu, Fe, Mn, Mo, Ni, Ti, V and Zn) from edible oils by producing detergentless micro-emulsions via an ultrasound-assisted extraction using a water phase containing Lipase at pH 3 as an extractant was developed. The trace elements in the water phase post-extraction were determined against matrix matched standards using ICP-MS. In the first step of the work, the parameters that affect extraction, such as pH, the volume of 1% lipase in the water phase and the ultrasonic and centrifugation times were optimized. Under the optimal conditions, …

The Burden Of Asthma In Oman, Nasser Al-Busaidi, Zulfikar Habibulla, Malvika Al-Lawati, Nabil, Yaqoub Al-Mahrouqi

Sultan Qaboos University Medical Journal

Asthma is a common lung disease worldwide, although its prevalence varies from country to country. Oman is ranked in the intermediate range based on results from the International Study of Asthma and Allergies in Childhood. A 2009 study revealed that the majority of asthmatic patients in Oman reported both daytime and nocturnal symptoms, while 30% of adults and 52% of children reported absences from work or school due to their symptoms. Despite these findings, there is little data available on the economic burden of asthma in Oman. The only accessible information is from a 2013 study which concluded that Oman’s …

Underlying Factors Behind The Low Prevalence Of Autism Spectrum Disorders In Oman : Sociocultural Perspective, Allal Ouhtit, Yahya Al-Farsi, Marwan Waly, Mostafa, Ishita Gupta, Omar Al-Farsi, Maha Al-Khaduri, Mohammed Al-Shafaee, Samir Al-Adawi

Sultan Qaboos University Medical Journal

Epidemiological surveys from various countries indicate an increased prevalence of autism spectrum disorders (ASD), leading researchers to debate whether there are now ‘more affected’ or ‘more detected’. The epidemiology of ASD in developing countries, such as Oman, has generally indicated a lower prevalence compared to developed countries in the West. In Oman, the prevalence is low; however, this article highlights some of the factors that could contribute to the appearance of a low ASD rate: cross-cultural variations in the presentation of distress; a lack of reliable biological markers for diagnosing ASD, and a lack of health services for children with …

Mining News Content For Popularity Prediction, Moayad Alshangiti

Theses

The problem of popularity prediction has been studied extensively in various previous research. The idea behind popularity prediction is that the attention users give to online items is unequally distributed, as only a small fraction of all the available content receives serious users attention. Researchers have been experimenting with different methods to find a way to predict that fraction. However, to the best of our knowledge, none of the previous work used the content for popularity prediction; instead, the research looked at other features such as early user reactions (number of views/shares/comments) of the first hours/days to predict the future …

The Human Ecology Dialectic: Culture As A Behavioral Adaptation, Marcia S. Taylor

The Hilltop Review

Contrary to popular thought, which implicated the disengagement of Marx from anthropological theory, his dialectical concept will be applied to explain human ecology in a Boasian historical particularism milieu. Environmental conditions will be the common denominator for the Darwinian biogeography theory, intertwined with the cultural adaptation theory of Boas within the Human Ecology Dialectic (Taylor, 2014). Anthropologically, in a biological context the theories will explain the behavioral adaptation process demonstrated culturally by the prehistoric ancestors of the Inuit of the Canadian Central Arctic in their development and essential engagement in the creation of art; a pursuit that became a cultural …

Reproductive Genetics: Desired Genes, Gendered Ethics, And Eugenic Echoes, Marykate K. Bodnar

The Hilltop Review

Present knowledge of genetics and assisted reproduction make fertile ground for a new type of eugenics: reproductive genetics. Proponents of reproductive genetics aim to separate these techniques from the problematic and negative connotations associated with historical eugenic policies by claiming them as part of the liberal eugenic movement. In-vitro fertilization (IVF), the market for sperm and eggs, and prenatal genetic testing allow conscious decision-making regarding the potential genetic make-up of children. Decisions are made in a gendered and politicized environment, shaping understandings of genes, eggs, and sperm around stereotypes and ideal social norms. In choosing “desirable” characteristics, whatever they may …

The Effects Of Humorous Facebook Posts On Messenger Credibility And Social Attractiveness, Brett A. Stoll

The Hilltop Review

The purpose of this study was to determine the effect that humorous Facebook messages have on perceived source credibility and social attractiveness. Social networking sites (SNS) such as Facebook continue to rise in popularity, solidifying their ongoing presence and influence for the foreseeable future. As users continue to look for ways to manage interpersonal impressions online, many turn to humor in public wall posts and message feeds. With humor proliferating the content of nearly 20% of Facebook posts, it begs the question of what effect its use has on impression management. To address this question, the researcher asked 283 participants …

Predictive Modeling Of Oxygen Transmission Through Micro-Perforations For Packaging Applications, Ayman Abdellatief, Bruce A. Welt, Jason Butler, Eric Mclamore, Arthur Teixeira, Sanjay Shukla

Journal of Applied Packaging Research

Methods for creating precise perforations in respiring produce packaging are being increasingly adopted. Knowledge of oxygen transfer through perforated packaging and oxygen distribution in packages is necessary for successful packaging design of fresh produce. An approach to modeling perforated packaging performance was developed using a cylindrical chamber with precision perforations using Fick’s second law. The model was simulated using two techniques including Finite Element Method (FEM) using commercially available software and Finite Volume Method (FVM) through programming. Perforations were approximated as a source term in the second method. Both simulation techniques showed trends similar to experimental data.

Triatominae (Hemiptera:Reduviidae) In Texas: Mitochondrial Genome Assembly, Trypanosoma Cruzi Detection, And Bacterial Community Analysis, Chissa-Louise Rivaldi

Biology Theses

The genus Triatoma contains vectors of the protozoan parasite Trypanosoma cruzi, the pathogen responsible for Chagas disease. The following research presents several inductive studies to develop vector control approaches targeted to the genus or species level. Two-hundred and eighty-two insects were collected, identified, and tested for the presence of T. cruzi. Four species of the Triatoma genus were collected - the overall incidence of T. cruzi was 52% (T. gerstaeckeri -51%, T. lecticularia – 92%, other, 29%). From these 282 insects, the bacterial communities of eight specimens of T. gerstaeckeri were sequenced and analyzed using pyrosequencing technology. The bacterial communities …

Lessons From Trypanosome Tfiih: Discovery Of The Essential Roles Of Crk9 In Gene Expression And Of The Divergent Helicase Paralog Xpb-R In Nucleotide Excision Repair, Nitika Badjatia

Doctoral Dissertations

Eukaryotic TFIIH consists of a core of seven subunits, including the DNA helicase Xeroderma Pigmentosum B (XPB), and a cyclin-dependent kinase (CDK)-activating complex (CAK) that contains CDK7. XPB is crucial for DNA unwinding during transcription and nucleotide excision repair (NER) while the CAK complex phosphorylates RNA polymerase II (RNAPII) carboxy terminal domain (CTD), enabling the enzyme’s promoter clearance.

Trypanosoma brucei, Trypanosoma cruzi and Leishmania spp. are lethal human parasites, belonging to the early-diverged order Kinetoplastida. They transcribe genes polycistronically and require spliced leader (SL) trans splicing for the maturation of mRNAs from polycistronic precursors. SL RNA gene (SLRNA) …

The Role Of Emotional Support Consistency And Child Risk Factors In Predicting Pre-K Cognitive And Social-Emotional Development, Amy Lynn Cannell-Cordier

Dissertations and Theses

The quality of children's daily experiences in preschool classrooms is predictive of their school readiness and later achievement (Duncan et al., 2007; La Paro & Pianta, 2000). One particularly important aspect of these experiences is the quality of emotional support provided by teachers and peers in the classroom (Hamre & Pianta, 2005; Howes et al., 2008; Mashburn, 2008; National Center on Quality Teaching and Learning, 2012). Traditionally, emotional support quality has been calculated as the average of ratings taken across the school year and is meant to represent children's average daily experience, without regard to any variability which exists within …
