Characterisation of Bidor Kaolinite and Illite

Two types of commercial clay minerals from the Bidor region of Perak were studied. From the X-ray diffraction study, these clays were identified as disordered kaolinite and 2 M polymorph of illite. The morphologies, the surface properties, the pore structures and the infrared absorption properties were examined. The basis for the identification of these clays is discussed

The influence of joints and composite floor slabs on effective tying of steel structures in preventing progressive collapse

The event of the terrorist attack at 11th September 2001 in the USA has attracted increasing attention of researchers and engineers on progressive collapse of structures. It has gradually become a general practice for engineers to consider progressive collapse resistance in their design. In this paper, progressive collapse of steel frames with composite floor slabs is simulated by the finite element method. The numerical results are compared with test results. The influence of the joints and the concrete slabs on the effective tying of steel beams is investigated through parametric studies. From the analysis, methods of preventing progressive collapse that can be considered in design and when retrofitting existing structures are proposed. The results show that retrofitting a structure with pre-stressed steel cables and an increase of crack resistance in the concrete near joints can effectively improve effective tying of a structure, which results in an enhanced structural capacity in preventing progressive collapse

Migrated guidewire: an unusual cause for recurrent aural polyps

Aural polyps are secondary to multiple ear pathologies, most commonly inflammatory or cholesteatoma related. Here, we present a rare case of recurrent aural polyps caused by guidewire migration into the middle ear with serious systemic complications and our attempts at removal

Dual tongue: the unexpected origin

Laryngeal lipoma is a very rare benign laryngeal tumour. Although it has an indolent growth, laryngeal lipoma can lead to compression and obstruction at upper aero digestive tract which leads to dysphagia, dyspnoea and hoarseness. Case Report: A 26-year-old man who came with presenting complaint that he developed a second tongue recently. His voice has turned muffled. Examination showed an accessory tongue appeared to arise from supraglottic region from nasoendoscopy. A transoral endoscopic excision of the lipoma was done. He has a complete resolution of symptom immediately following surgery with no recurrence on follow up. Conclusion: A complete excision of laryngeal lipoma is important as its location may cause mechanical narrowing of upper aerodigestive tract, giving symptoms of airway obstruction and difficulty swallowing. We highlighted the structures that may involve in laryngeal lipoma and its type

Biosorption of heavy metals using Pleurotus Ostreatus fungal mycelium from mushroom farming waste / Prof. Sr. Ir. Dr. Suhaimi Abdul Talib … [et al.]

Industrial wastewater containing heavy metals are hazardous, which pose a detrimental health implication to human and environment. Global industrialization development has increased the discharge of this dangerous industrial wastewater to surface water. It is of great concern nowadays due to its toxicity, non-biodegaradable and cumulative characteristics. Heavy metals, such as lead, cadmium, copper, nickel and mercury, are from metal plating, painting and metal finishing industries. The most commonly used method in heavy metals treatment for industrial wastewater is precipitation with caustic soda. However, this method generates a large amount of hydroxide sludge which need further disposal. In view of this, interest which focus on green sustainable biosorption process, has been intensified among researchers recently. Biosorption is a passive metabolic independent process involving physico-chemical binding of metal ions with biosorbent, which from nonliving biological materials. The biosorbent offers two major advantages, namely, renewable and cost effective. It is easily regenerated by using diluted acid for reuse and transformed from available large amount of bio-waste to wealth. Biosorbents from agricultural and industrial waste which are available in respective countries, such as Brazil, India, Pakistan, Iran, China and Turkey have been investigated. Fungal Pleurotus ostreatus (Chia-Chay et a/., 2011, Javaid et a/., 2011) and sawdust (Zakaria et a/., 2009) are promising biosorbents due to their high heavy metals removal efficiency if compared to other plant or bacteria derived biosorbents. To date, there is lack of information on biosorption of Pleurotus ostreatus Mushroom Spent-Substrate (PSMC) in wastewater heavy metals treatment. Generally, the PSMC is an agricultural waste of mushroom cultivation farm in Malaysia, which majorly consists of rubber tree sawdust and Pleurotus ostreatus mycelium. The disposal of PSMC is currently handled by open-burning or converted into low commercial value organic fertilizer in order to reduce cost for solid waste disposal. Studies on PSMC as a potential biosorbent for heavy metals treatment is yet to be explored. Meanwhile in biosorption study, the half saturation constant of biosorption evaluation is seemed hardly been carried out as a time saving approach for this alternative sustainable technology. Presently, little research is applying the Artificial Neural Networks (ANN) in biosorption study. Kardam and co-researchers (2010) reported that constructed ANN models were highly precise in predicting the single output variable. In fact, such single output ANN network has a limitation in simulation of biosorption operating system for prediction of effluent quality and the best time for elution of biosorbent under any operating conditions. This study is thus expected to make contribution to the knowledge of scale-up biosorption of heavy metals technology. This study focuses on biosorption characteristics of heavy metals biosorption from aqueous solution by deploying PSMC. The half saturation constant of heavy metals biosorption and the best operating parameters of initial pH, contact time and initial heavy metals concentration were optimized. Biosorption data were fitted to established isotherm, kinetic and thermodynamic models. Concurrently, mechanisms of heavy metals biosorption were studied. Application of biosorbent was evaluated in industrial wastewater. Furthermore, a constructed ANN modelling with two output in biosorption study is explored. This study is not only parallel with green sustainable technology for heavy metals treatment but also waste management

One-stop microvascular screening service: an effective model for the early detection of diabetic peripheral neuropathy and the high-risk foot.

AIMS: To evaluate the feasibility of a one-stop microvascular screening service for the early diagnosis of diabetic distal symmetrical polyneuropathy, painful distal symmetrical polyneuropathy and the at-risk diabetic foot. METHODS: People with diabetes attending retinal screening in hospital and community settings had their feet examined by a podiatrist. Assessment included: Toronto Clinical Neuropathy Score evaluation; a 10-g monofilament test; and two validated, objective and quick measures of neuropathy obtained using the point-of-care devices 'DPN-Check', a hand-held device that measures sural nerve conduction velocity and amplitude, and 'Sudoscan', a device that measures sudomotor function. The diagnostic utility of these devices was assessed against the Toronto Clinical Neuropathy Score as the 'gold standard'. RESULTS: A total of 236 consecutive people attending the retinal screening service, 18.9% of whom had never previously had their feet examined, were evaluated. The prevalence of distal symmetrical polyneuropathy, assessed using the Toronto Clinical Neuropathy Score, was 30.9%, and was underestimated by 10-g monofilament test (14.4%). The prevalence of distal symmetrical polyneuropathy using DPN-check was 51.5% (84.3% sensitivity, 68.3% specificity), 38.2% using Sudoscan foot electrochemical skin conductance (77.4% sensitivity, 68.3% specificity), and 61.9% using abnormality in either of the results (93.2% sensitivity, 52.8% specificity). The results of both devices correlated with Toronto Clinical Neuropathy Score (P<0.001). A new diagnosis of painful distal symmetrical polyneuropathy was made in 59 participants (25%), and 56.6% had moderate- or high-risk foot. Participants rated the service very highly. CONCLUSIONS: Combined, eye, foot and renal screening is feasible, has a high uptake, reduces clinic visits, and identifies painful distal symmetrical polyneuropathy and the at-risk foot. Combined large- and small-nerve-fibre assessment using non-invasive, quantitative and quick point-of-care devices may be an effective model for the early diagnosis of distal symmetrical polyneuropathy
