Smart Electricity Billing System Using Blockchain Technology

Nowadays, many home appliances use electricity to operate. However, prediction of the electricity usage is not easy and accurate. A prepayment scheme provides the better way to forecast domestic electricity usage. Traditionally, the prepayment scheme is based on the centralized server or the standalone embedded machine, but the centralized service is highly vulnerable to security threats and potential attacks. The purpose of this paper is to describe our design of a peer-to-peer token bill system for the domestic electricity distribution. It also describes the trusted information transaction among the Internet-of-Things devices. In addition, we provide a conceptual overview of the blockchain-based Wattcoin payment system. In this system, a wallet is created by using the cryptography technique that generates private key, public key and the wallet address. Then, the transaction is done when the digital signature is used to authenticate every transaction floating in the network. Moreover, this paper illustrates blockchain message protocol for message exchange among devices

Properties of wood polymer nanocomposites impregnated with ST-co-EDA/nanoclay

Study has been made on manufactured wood polymer nanocomposites (WPNC) from Sesendok wood through impregnation of Styrene (ST), Ethyldimethylamine (EDA) and Montmorillonite (MMT) nanoclay. The impregnation process of the wood samples by vacuum-pressure method with in-situ polymerization of prepolymer mixture was used. The wood samples structural properties were investigated with Dynamic Mechanical Thermal Analysis (DMTA), Fourier Transform Infrared (FTIR), X-ray Diffraction (XRD) analysis and Scanning Electron Microscopy (SEM) found to be extensively changed upon ST-co-EDA/MMT impregnated. The mechanical properties of the WPNC samples were significantly increased by ST-co-EDA/MMT treatment. Thermal properties of WPNC samples were also evaluated using themogravimetric analysis (TGA) and an improvement in thermal stability was found for WPNC. WPNC has shown excellent resistance against weathering effect while exposed to surrounding. WPNC can be used to replace plastic and synthetice materials for its excellent properties and high market demand of the modern society

A Potentially Disastrous Life -Threatening Complication of Emergency Tube Thoracostomy in A Simple Case of Spontaneous Pneumothorax

Emergency tube thoracostomy carries risks of infective and technical complications. The aseptic technique is essential to prevent infections, while blunt dissection method can minimise the associated technical complications. Preparation and adherence to protocols as well as appropriate knowledge and skills, however, are of utmost importance to reduce risks of complications. Physicians must have adequate knowledge of anatomy and the procedure to ensure for accurate site tube placement without any complication. This case illustrates how a failure to appropriately use the instrument resulted in a displaced scalpel blade inside the thoracic cavity. It caused an unnecessary thoracotomy for blade retrieval. The mishap escalated a simple procedure to the potentially disastrous life-threatening event

Impact of nanoclay on the properties of wood polymer nanocomposites

In this chapter, the influences of nanoclay on the attributes of tropical wood polymer nanocomposites (WPNCs) were discussed. The impregnation of wood samples with nanoclay and in situ polymerization were employed by vacuum-pressure method. The comparisons of improvement in different properties have been showed between the raw wood, wood plastic composites (WPC), and WPNC. The FTIR result confirmed the interaction and incorporation of nanoclay inside wood. The exfoliation of nanoclay has been identified by Transmission electron microscopy result. The formation of wood polymer nanocomposites was proven through X-ray diffraction (XRD) pattern and Scanning electron microscopy (SEM) images, respectively. Significant improvement in mechanical properties was found through nanoclay treatment. The Dynamic mechanical thermal analysis (DMTA) result also indicated the improvement of thermo-mechanical properties after nanoclay treatment. The storage modulus (E’) of the WPNC specimen also unveiled notable enhancement in both rubbery plateau and glassy region in alliance to their parallel wood polymer composites and raw wood samples. The wood’s Dynamic Young’s modulus (Ed) also indicated significant increment for PF-nanoclay impregnated WPNC samples. Whereas, the treatment by PF-nanoclay system seem to lower the damping (loss Tanδ) peaks of woods. Furthermore, the WPNC samples shown significant improved compared to WPC and raw ones against white-rot white-rot (polyporous versicolor) and brown-rot (postia placenta) exposed

The Beautiful Mind : A Case Report

Caring for a family member diagnosed with schizophrenia will not only impart a lifetime of emotional distress but also social and financial challenges. Failure to anticipate and cope with the burden of care responsibilities will add unnecessary risk to permanent injury resulting in substandard management of the patient and even death. We describe a case of successful removal of nine (9) constricting rings from the finger of both hands in a poorly taken care of an abusive relapse schizophrenia patient using an oscillating saw and ring cutter under procedural sedation combined with wrist block in the emergency department (ED). Early recognition and definitive treatment are of paramount importance to avoid irreversible ischemia and gangrene. The possible risk of negligence should be kept in mind bearing a link with depression among members caring for schizophrenia.

Pancreatic surgery outcomes: multicentre prospective snapshot study in 67 countries

Background: Pancreatic surgery remains associated with high morbidity rates. Although postoperative mortality appears to have improved with specialization, the outcomes reported in the literature reflect the activity of highly specialized centres. The aim of this study was to evaluate the outcomes following pancreatic surgery worldwide.Methods: This was an international, prospective, multicentre, cross-sectional snapshot study of consecutive patients undergoing pancreatic operations worldwide in a 3-month interval in 2021. The primary outcome was postoperative mortality within 90 days of surgery. Multivariable logistic regression was used to explore relationships with Human Development Index (HDI) and other parameters.Results: A total of 4223 patients from 67 countries were analysed. A complication of any severity was detected in 68.7 percent of patients (2901 of 4223). Major complication rates (Clavien-Dindo grade at least IIIa) were 24, 18, and 27 percent, and mortality rates were 10, 5, and 5 per cent in low-to-middle-, high-, and very high-HDI countries respectively. The 90-day postoperative mortality rate was 5.4 per cent (229 of 4223) overall, but was significantly higher in the low-to-middle-HDI group (adjusted OR 2.88, 95 per cent c.i. 1.80 to 4.48). The overall failure-to-rescue rate was 21 percent; however, it was 41 per cent in low-to-middle-compared with 19 per cent in very high-HDI countries.Conclusion: Excess mortality in low-to-middle-HDI countries could be attributable to failure to rescue of patients from severe complications. The authors call for a collaborative response from international and regional associations of pancreatic surgeons to address management related to death from postoperative complications to tackle the global disparities in the outcomes of pancreatic surgery (NCT04652271; ISRCTN95140761)
