Abstract:

Dual-fuel engines are modified compression ignition engines, where the primary source of fuel is a gaseous fuel, and ignition is provided by a ‘pilot’ injection of a reduced quantity of diesel. The generally accepted understanding of the dual-fuel engine describes its combustion process as proceeding in three stages. Initially, around half of the pilot will burn and entrain some gaseous fuel into an overall fuel-rich process. Subsequently, the remaining pilot fuel burns and entrains an increasing amount of the primary fuel into its reaction zone. In the final stage, a flame propagation process

The reconstruction of nasal stenosis secondary to burns can be challenging due to the limitation of localized tissue, rate of recurrence, and burn injury to the surrounding areas. A vascularized composite flap of local composite tissue (forked flap) from the lip can reliably reconstruct the nasal vestibule and nasal sill diminishing the risk of recurrent nasal stenosis.

Burn patients have low level of immunity, lack skin barrier and are prone to infections. Due to these facts, they have less ability to fight against the corona virus, so surgical practices for management of burn patients should be modified to prevent the spread of infection and decrease mortality.

The thin, fibrous structure of shredded stem modifies the burn characteristics of the cigarette.

Abstract:

A model is developed to explore fire–atmosphere interactions due to the convective sink and vorticity sources in a highly simplified and idealized form, in order to examine their effect on spread and the stability of various fire front geometries. The model is constructed in a cellular automata framework, is linear, and represents a background flow, convective sink, and vortices induced by the fire plume at every burning cell. We use standard techniques to solve the resulting Poisson equations with careful attention to the boundary conditions. A modified Bresenham algorithm is developed to rep

Abstract:

In this paper, a flexible distribution with increasing, bathtub and inverted bathtub hazard rate called Modified Burr III-Power (MBIII-Power) is developed on the basis of the generalized Pearson differential equation. The density function of MBIII-Power is arc, exponential and positively skewed shaped. Descriptive measures such as quantiles, moments, incomplete moments, inequality measures, residual life functions and reliability measures are theoretically established. The MBIII-Power distribution is characterized via different techniques. Parameters of MBIII-Power distribution are estimated u

Each identified isolate of P. aeruginosa was subjected to in vitro antibiotic susceptibility test by using modified Kirby-Bauer disc diffusion method. Two imipenem (10μg) disks were placed on the surface of the agar plate in which one of them was added with 5μl of 0.5M E

Abstract:

Accelerated life tests (ALTs) are used to make timely assessments of the life time distribution of highly reliable materials and components. Much of the previous work on ALTs has focused on constant-stress, step-stress, ramp-stress schemes and their various combinations. In the literature ramp-stress ALTs that have been formulated can be conducted when more than one test chambers are available; installation of which may prove to be costly. Even when one test chamber is used the stress rate remains constant throughout the duration of the experiment. It is not only necessary but imperative to ex

Abstract Background Drain insertion following chronic subdural hematoma (CSDH) evacuation improves patient outcomes. Objective To examine whether this is influenced by variation in drain location, positioning or duration of placement. Methods We performed a subgroup analysis of a previously reported multicenter, prospective cohort study of CSDH patients performed between May 2013 and January 2014. Data were analyzed relating drain location (subdural or subgaleal), position (through a frontal or parietal burr hole), and duration of insertion, to outcomes in patients aged >16 yr undergoing bu

Abstract:

Burning of pastures is a management practice adopted by graziers worldwide. When rain falls on burnt pastures, it can lead to increased pollutant transport in runoff. However, this transport can be modified by vegetative buffers which intercept the runoff downslope of burnt areas. This study examines the effects of different pasture buffer lengths (0, 2, and 5 m) on sediment and chemical transport from two pasture sites near Wivenhoe Dam, the main water reservoir for Brisbane City. Simulated rainfall (100 mm/h) was applied to 18 plots on pasture sites after they were burnt, and insoluble and s

Abstract:

This paper describes the effects of wildfire on the nesting behaviour of some species of birds in a heathland community at Gooseberry Hill, Western Australia. The most severe fire during the nine year (1981-89) study was a hot summer burn in January 1985, which destroyed 95% of the study area. In the spring following that fire, 81% of the species previously known to breed in the area were still able to nest. The nesting substrate, height, site and aspect for three of the most abundant species (splendid fairy-wrens, western thornbills and yellow-rumped thornbills) were examined in detail. In th

The current state of the building ceramics production is based on the following facts. Firstly, as a result of market conditions, the number of operating ceramics factories has significantly decreased. Secondly, considering the increase in the house construction rate due to the shift to new financing mechanisms, there has been an increase in the ceramic brick production by 2-3% since 2019. Growth opportunities are associated with higher thermal efficiency of ceramic products and masonry based thereon.

In this paper, we first study a new two parameter lifetime distribution. This distribution includes “monotone” and “non-monotone” hazard rate functions which are useful in lifetime data analysis and reliability. Some of its mathematical properties including explicit expressions for the ordinary and incomplete moments, generating function, Renyi entropy, δ-entropy, order statistics and probability weighted moments are derived. Non-Bayesian estimation methods such as the maximum likelihood, Cramer-Von-Mises, percentile estimation, and L-moments are used for estimating the model parameters. The i

Clean and highly efficient internal combustion engines will still be necessary in the future to meet the ambitious CO2 emissions reduction targets set for light-duty vehicles. The maximal efficiency of stoichiometric Spark-Ignited (SI) gasoline engines has been steadily increasing in recent years but remains limited by the important relative share of cooling losses. Low heat rejection engines using ceramic barrier coatings have been presented in the past but smart insulation coatings are gaining a renewed interest as a more promising way to further increase the engine maximal thermal efficienc

ABSTRACTChronic subdural hematoma (CSDH) is one of the most common neurosurgical conditions. Despite ongoing efforts, recurrence and reoperation rates after surgical treatment remain high. We synthesize scientific evidence on the treatment of CSDH with biophysical principles and then propose a simple and effective surgical technique aiming to reduce the recurrence rate. Under local anesthesia, one burr hole is placed in the area above the maximum hematoma thickness. One drain is inserted into the dorsal direction to the deepest point of the hematoma cavity, and a second drain is inserted front

Abstract Pseudomonas aeruginosa and Acinetobacter baumannii are the bacteria which increasingly account for nosocomial infections. Due to high virulence, the rate of Multi-Drug Resistance (MDR) and limited availability of new agents, these infections create significant clinical burdens, making it important to identify the possible sources of their occurrence. The aim of this study was to assess non-lactose fermenting bacteria and their metallo-β-lactamase (MBLs) genes expression in the Burn Intensive Care Unit (BICU) patients’ saliva samples.
