Deposition And Characterization Of Polyfluorene / Cerium Oxide Organic-Inorganic Thin Films

The investigation of a novel approach by applying an organic polyfluorenes (PFs) layer on inorganic high dielectric constant (k) cerium oxide (CeO2) film for potential use as passivation of silicon (Si)-based metal-oxide-semiconductor (MOS) devices was carried out. Initially, the effects of post-deposition annealing temperatures (400, 600, 800, and 1000 °C) was carried out onto the CeO2 films in order to investigate the changes of temperatures onto structural, morphological, optical and electrical characteristics of the CeO2 films. Subsequently, different composition of PFs was dissolved in toluene and deposited onto indium tin oxide glass substrate to examine the effects of varying PFs composition onto the optical, structural, morphological and electrical properties of the PFs. The optimised PFs composition was then applied as an overlayer stacked on CeO2 films post-deposition annealed at different temperatures to fabricate functional Al/PFs/CeO2/Si/Al hybrid organic-inorganic Si-based MOS device, which was relatively new. Structural, morphological, optical, and electrical properties demonstrated by the stacking PFs on CeO2 films were compared with the samples consisting of single CeO2 films. Outcome of the study revealed that the samples having stacking of PFs on CeO2 films could not surpass the performance provided by single CeO2 films. Nonetheless, the stacking of PFs on CeO2 films provided a breakthrough in the context as a potential high k passivation layer to replace the conventional low k silicon oxide (SiO2) due to the adequately higher k value and comparable current-voltage characteristics with CeO2

Development on Orthotics Insole for Flat Feet Focusing on Sport Usage Evaluated by Electromyography

Running is a method of terrestrial locomotion allowing humans to move rapidly on foot, which related to the movement of lower limb. But for flat feet, running or walking for a long period will give them a high-risk associate with a foot pain. In order to reduce the foot pain, an arch orthotics insole is advised to be wore by the flat feet. This paper provides an extensive study on orthotics insole focusing on sport usage for flat feet. For this silicon rubber Orthotics Insole is designed with sufficient arch support, sufficient thickness, metatarsal pad, heel pad, heel cup and ergonomics dimension specification. The objectives of this research are to design and improve the efficiency of orthotics insole for flat feet focusing on sport usage. Both new orthotics insole and existing insole will be evaluated by using electromyography (EMG) that will record the electrical potential which generated by muscle cells. The output of time domain feature and frequency domain feature for both insoles will be analyzed and compared. This Orthotics Sport Insole ideal to be used by flat feet especially during their sport activity specifically running in order to reduce muscle pain to prevent injuries

Luminescence Characteristics Of Hybridized Polyfluorene

In the present work, polyfluorenes hybridized with silicone were prepared at a fixed volume ratio before subjected to post-mixing treatment at different temperatures. Systematic investigation of the prepared samples in terms of luminescence properties has been carried out with the assistance of photoluminescence and electroluminescence characterization tools. With the increase of temperature, a minute change in the aspects of CIE chromaticity, luminescence intensity, and emission wavelength was observed. Detailed explanation with regards to the research findings will be discussed and related with structural, morphological, and electrical properties of the samples using high-resolution X-ray diffraction, atomic force microscopy, field emission scanning electron microscopy, and hall effect measurement. Potential application of the polyfluorenes hybridized with silicone in light emitting diode (LED) was also shown in this work

Metastatic Prostate Cancer Synchronous with Male Breast Papillary Ductal Carcinoma in situ: Management Dilemma and Literature Review

Prostate cancer is common in men, but tumour of the male breast is rare. For these two tumours to be presented synchronously in a male patient is even rarer. The focus of this paper is the case of a 72-year-old man diagnosed with papillary ductal carcinoma in situ after he presented with a unilateral breast mass associated with nipple discharge. Imaging staging for his breast tumour and subsequent prostate biopsy found an incidental synchronous asymptomatic prostate adenocarcinoma as well as bone metastases. He denies risk factors for malignancies and refuses genetic testing. The first part of our discussion will highlight the uncommon occurrence of male breast ductal carcinoma in situ and its management controversies. The subsequent part of our discussion will focus on the association between male breast cancer and prostate cancer, and implication of this on the future treatment of these patients. More importantly, our case will illustrate the challenges in managing dual primaries that present concurrently

Reducing the environmental impact of surgery on a global scale: systematic review and co-prioritization with healthcare workers in 132 countries

Abstract Background Healthcare cannot achieve net-zero carbon without addressing operating theatres. The aim of this study was to prioritize feasible interventions to reduce the environmental impact of operating theatres. Methods This study adopted a four-phase Delphi consensus co-prioritization methodology. In phase 1, a systematic review of published interventions and global consultation of perioperative healthcare professionals were used to longlist interventions. In phase 2, iterative thematic analysis consolidated comparable interventions into a shortlist. In phase 3, the shortlist was co-prioritized based on patient and clinician views on acceptability, feasibility, and safety. In phase 4, ranked lists of interventions were presented by their relevance to high-income countries and low–middle-income countries. Results In phase 1, 43 interventions were identified, which had low uptake in practice according to 3042 professionals globally. In phase 2, a shortlist of 15 intervention domains was generated. In phase 3, interventions were deemed acceptable for more than 90 per cent of patients except for reducing general anaesthesia (84 per cent) and re-sterilization of ‘single-use’ consumables (86 per cent). In phase 4, the top three shortlisted interventions for high-income countries were: introducing recycling; reducing use of anaesthetic gases; and appropriate clinical waste processing. In phase 4, the top three shortlisted interventions for low–middle-income countries were: introducing reusable surgical devices; reducing use of consumables; and reducing the use of general anaesthesia. Conclusion This is a step toward environmentally sustainable operating environments with actionable interventions applicable to both high– and low–middle–income countries

Adoption of innovation among beef cattle farmers in Peninsular Malaysia

Cattle farming has become one of the engine growth in agriculture industry since years ago. The role of this sector is assumed as essential to supply protein source for the population. However, the problem arises when the import rate for beef is higher, and the supply has failed to meet the population's demand. Hence, the introduced innovation such as artificial insemination, integration and feedlot technique is seen as a driver that can further accelerate this sector. The cooperation and involvement from other parties, including the government and private sector are essential to ensure the successfulness of the introduced innovation. This study examines the socio-demographic profile and the adoption level of beef cattle farmers in four regions of Peninsular Malaysia. Multi-stage random sampling has been employed, and 233 farmers have involved as the respondents of this study. The farmers' average age is 48 years and had 13 years of experience in beef cattle farming. Most of the farmers found that they had a high level of innovation adoption, but certain of them face some obstacles such as financial and extension issues, which had hindered them from adopting innovation. The involvement of all stakeholders, including research centres, manufacturing and farmers, will benefit each other as the product can be supplied as the sample to enhance beef cattle production. Hence, a harmony and competitive situation can be created to ensure the food security of the country
