Wear behavior and mechanical properties of al-based FGM

The wear and mechanical properties of Aluminium, Al LM6 and Al/SiC Functionally Graded Material (FGM) which are produced by using horizontal centrifugal casting method have been studied. Two casting parameters with three different level are selected to produce the hollow cylinder namely pouring temperature (690, 710 and 725°C) and motor speed (1300, 1500 and 1700rpm). Taguchi method is used in the analysis to screen all the variables that have significant effects on the wear rate and mechanical properties of Al-based FGM. Furthermore, the optimization of Response Surface Methodology (RSM) is utilized to acquire a model that predict the optimum process parameter. The result indicates that the influencing parameter are load and type of material, and the best wear samples for this level of parameters are Al/SiC with pouring temperature of 725°C, motor speed of 1500 rpm, load of 10 N and sliding velocity of 1 m/s. Meanwhile, types of material are the most influencing parameter for hardness and strength analysis. Graded properties of Al-based FGM are observed from inner towards the outer periphery of the sample. The size of Si is bigger and concentrated at the inner periphery while SiC particles segregate towards the outer periphery due to its high density compared with Aluminium. Results revealed that all composites casted have the best hardness, strength and wear resistance at the outer periphery of the hollow cylinder

Biological endophenotypes of prodromal psychosis and depression

The identification of biomarkers to predict risk and clinical outcomes beyond clinical observation in psychiatry is a key priority in contemporary mental health research. Individuals at elevated risk for mental disorders have been the focus of such efforts as they represent a potentially viable target group for early intervention and indicated prevention. Early intervention and indicated prevention efforts for individuals at ultrahigh risk (UHR) for psychosis might benefit from such biomarkers to enable better risk prediction and to discern who will benefit from treatment. Alterations in neuroendocrine, immune and oxidative stress markers as well as abnormalities in lipid biology are robust findings in biological psychiatry. On the other hand, mounting evidence suggests that First Nations people including the Aboriginal and/or Torres Strait Islander people of Australia have a higher risk for common and severe mental illness, most likely attributable to social and environmental health determinants. However the role of stress-related biomarkers in this context remains poorly understood. Consequently, the aims of this thesis were to examine (1) a multisystem biomarker index known as allostatic load in two high-risk populations and to (2) examine the role of lipid biology in these groups. The first part of this thesis explores the role of allostatic load (AL) and omega-3 (ω-3) polyunsaturated fatty acids (PUFA) in two clinical studies of patients with schizophrenia, first-episode psychosis and individuals at UHR for psychosis. The second part explores the role of AL and dietary ω-3 PUFA in a community-based study of Aboriginal and/or Torres Strait Islander people, who are at increased risk for mental ill-health according to recent national reports. The above aims are achieved through meta-analysis of existing studies of cortisol in psychotic disorders, secondary analysis of two clinical studies, and in a cross-sectional multi-site community-based study of Aboriginal and/or Torres Straight Islander adolescents and young adults attending a health check. First, flattened cortisol-awakening response is reported in patients with schizophrenia and first-episode psychosis relative to controls, but not in UHR individuals, suggesting neuroendocrine dysregulation during some stages of the psychosis spectrum. Secondly, informed by these findings, a study of AL demonstrated elevated AL in patients with schizophrenia and first-episode psychosis that was positively correlated with positive psychotic symptoms and negatively correlated with functioning at trend level. No prospective association of AL and treatment response and symptomatic ix remission was identified. Next, secondary analysis of a multi-centre randomised controlled trial investigated AL in youth at UHR for psychosis. This study revealed prospective associations of high AL with impairments in social and occupational functioning. Next, the prospective association of PUFA status and clinical outcomes in a 12-month follow-up is reported, which demonstrated a selective relationship of low ω-3 PUFA levels with mood disorders and no association with psychotic or anxiety disorders. The second part of the thesis reports depression rates in three remote communities, explores the relationship of depression with hair cortisol and AL, and reports an association of low plasma levels of o ω-3 PUFA with depressive symptoms. Collectively, the data presented in this thesis demonstrate complex associations of a multisystem biomarker index and ω-3 PUFA with mental ill-health. Ultimately, multisystem indices like AL may be used in future research to establish their utility as a clinical prognostic risk index. By studying membrane lipids in an ethnic minority group, this thesis was able to show an association of high dietary intake of ω-3 PUFA and low levels of depression, which may serve as a protective factor

Diversity Casting Within Reality TV Competitions

When it comes to casting in reality TV competition shows, many of the casts suffer from an imbalance in diversity, allowing majority white players to stick together and eliminate the few minority players every season. This paper deals with deconstructing how casting works as well as offering up solutions for change to the broken system

Evaluation of the Results of Professional Development of Mathematics Teachers in East Nusa Tenggara Province

Literatur saat ini telah menyoroti tantangan dan peluang untuk pengembangan profesi guru di Indonesia. Namun studi yang secara khusus mengevaluasi pengembangan profesi guru matematika masih sedikit. Terkait hal tersebut, penelitian survei ini dilakukan untuk menjelajahi kendala yang dihadapi para guru matematika setelah mengikuti pendidikan profesi. Penelitian ini melibatkan 195 guru matematika yang tersebar di tujuh kabupaten. Instrumen penelitian adalah tautan kuesioner berupa googleform yang disebarkan menggunakan grup WhatsApp. Hasil penelitian ini menunjukkan bahwa para guru menghadapi tantangan dalam perencanaan pembelajaran, mengalami keterbatasan waktu karena jadwal mereka yang padat. Akses terbatas terhadap materi pengajaran, teknologi, dan sumber daya pengembangan profesional terkini dalam memberikan layanan terbaik. Evolusi paradigma pendidikan, perubahan kurikulum, dan pergeseran pedagogis yang cepat dapat menjadi tantangan bagi guru yang sedang bertugas untuk mengimbanginya, yang membutuhkan pengembangan profesional dan kemampuan beradaptasi yang berkelanjutan. Current literature has highlighted the challenges and opportunities for teacher professional development in Indonesia. However, studies that specifically evaluate mathematics teacher professional development are still few. In this regard, this survey study explored the obstacles mathematics teachers face after undergoing professional education. This study involved 195 mathematics teachers spread across seven districts. The research instrument was a questionnaire link in a Google Form distributed using a WhatsApp group. The results of this study indicate that teachers face challenges in lesson planning, experiencing time constraints due to their busy schedules. Limited access to the latest teaching materials, technology, and professional development resources hinders providing the best service. The rapid evolution of educational paradigms, curriculum changes, and pedagogical shifts can be challenging for in-service teachers to keep up with, which requires continuous professional development and adaptability
