Microscopic observations of needle and soft-tissue simulant interactions

Currently, physicians have no means of correctly estimating the needle tip location during percutaneous needle insertion. A model of needle-tissue interaction that predicts the needle tip location would assist physicians in pre-operative planning and hence improve needle targeting accuracy. This study is aimed to investigate the interactions of bevel-tipped needles and soft tissue in situ, using agarose gel as a soft-tissue simulant. An experimental setup is designed to record the needle-gel interaction forces and torques during needle insertion. Gel rupture during needle insertion is observed using a Laser Scanning Confocal Microscope and recorded in time series and three-dimensional images (Figure). Experimental results show the possibility of observing in situ gel rupture during needle insertion and relating them to the needle-gel interaction forces and torques. Moreover, it is seen that the maximum force along the insertion axis, |Fz max|, is proportional to bevel angle and inversely proportional to insertion speed. The maximum resultant torque, ||Tr max||, is found to be inversely proportional to bevel angle and proportional to insertion speed. However, the influence of the increase in insertion speed in |Fz max| and ||Tr max|| diminishes as insertion speed increases. These results concur with observations noted in gel rupture images

Factors That Influence Muslim Consumers Preference Towards Islamic Banking Products Or Facilities - Theory Of Reasoned Action

The purpose of this study is to identify the determinants of Muslim consumers’ intention whether to engage in Islamic banking facilities or not to engage. Ajzen and Fishbein’s (1980) Theory of Reasoned Action was used as a basis for this study. The theory posits that the immediate determinant of behavior is intention. Intention is determined by the weighted attitude toward the behavior and the weighted subjective norm. The variables under studied in this research were actual behavior, intention, attitude toward the behavior, subjective norm, and the external variables i.e. knowledge and religiosity. Combination of beliefs, evaluations, and motivation to comply determined attitude and subjective norm towards behavior

Optimalisering av driften ved Saulekilen Renseanlegg i Arendal kommune med hensyn på kjemisk felling og slamavvanning

The wastewater contains a lot of nutrients that can be harmful to nature, such as phosphorus. Therefore, to avoid negative consequences caused by these nutrients, it is desirable to minimize them before discharge. The chemical purification step consists of several processes, chemical precipitation, coagulation, flocculation, and separation. The main goal of these processes is to form large enough flocks of the precipitated particles so that they become large enough to be able to separate it from the wastewater by separation methods. The separated particles are passed on in the form of sludge where it is treated and thickened and centrifuged to dewater it. Arendal municipality doses based on the dosing table to reach a precipitation pH of 5,9 and in winter the plant struggles to thicken the sludge. This master thesis is about optimizing the operation of the Saulekilen treatment plant in Arendal municipality, about chemical precipitation and sludge dewatering. It also investigates whether the plant’s dosing table corresponds with results from the laboratory and which precipitation pH gives better results about phosphorus concentration in the outlet. Moreover, it explains the relationship between incoming wastewater and phosphorus concentration in the inlet and outlet, by analyzing the operation data. And whether road salt has any effect on the sludge’s drainage properties. Through analyzing the results from the laboratory, it shows that Arendal municipality overdoses chemicals to reach a precipitation pH of 5,9 when the water volume is above 60 l/s. Examination of Arendal municipality’s plant data shows that the larger the amount of water that enters, the lower the phosphorus concentration in the wastewater. The same applies to outlets. The sludge tests show that adding saline solution destroys the polymer bonds, makes the sludge more liquid and decreases the dewatering effect

Automated construction noise prediction by considering the variability of noise sources and outdoor sound propagation

Noise has become a serious concern due to increase of construction development. Continuous exposures to excessive noise result in physical, physiological and psychological effects. To reduce these effects, the prediction of noise from construction in the early planning stage is suggested. In Malaysia, the prediction is based on the BS5228: Part 1: 2009 procedure. However, the equivalent noise level (LAeq) prediction from BS5228 was claimed to be inaccurate, and previous research suggested that the primary solution is to predict noise using stochastic approach. Nonetheless, the predictions of noise using stochastic approach were not carried out in a detail manner and not all factors that may affect the noise were considered. Therefore, this study further investigates the accuracy of the noise prediction by using BS5228 procedure, followed by improving the method of noise prediction using stochastic approach and develops an automated model for noise prediction. Among considered factors include the variability of position and height of the sources, as well as receiver and variability of outdoor sound propagation. The automated model was designed using MATLAB’s Graphical User Interface (GUI) and produced equivalent continuous sound level, LAeq, standard deviation and other parameters of noise levels such as L10, L90 and Lmax. The accuracy between measured and predicted noise levels was measured using statistical tests in SPSS (Statistical Package for Social Science) software and also using MAPE (Mean Absolute Percentage Error) method. The result of t-test showed significant difference between LAeq obtained from measurement and BS 5228 procedure. Meanwhile, the comparison of LAeq between measurement and simulation was insignificant throughout t-test and overall, the results from MAPE method were also in the acceptable range. As a conclusion, noise prediction using Monte Carlo approach can be used as the alternative way in predicting noise from construction

VALENTINE DAY TIDAK HARUS MENUJU PERZINAHAN

Valentine's Day or what is known as Valentine's Day is very popular among young people and is the most eagerly awaited moment on February 14th. Valentine's Day is often celebrated every year so that it becomes a culture and a trend. Valentine's Day is synonymous with flowers, chocolates, dolls, and some people even celebrate this day with sex parties. This culture is practiced by young people from various countries and including Indonesia, which increasingly refers to the damage to Indonesian culture and morals. Therefore this research was carried out to make people aware of deviations from Valentine's Day and the negative impact on Indonesian culture and provide enlightenment from the aspects of religion, society, government and in the eyes of education.

Awareness of Microtakaful Development among Low-Income Earners in Malaysia

Malaysia is the third largest takaful market globally and the takaful sector in Malaysia shows sound growth in 2022. Takaful had a penetration rate of 20.1% in 2022, up from 18.6% the previous year. However, only 25% of adult employees in the low-income group have some form of life insurance or family takaful cover, in contrast with 59% of those who are employed in the overall population who have takaful or insurance protection. The Malaysian population can be classified into three income segments: the T20 group, the M40 group and the B40 group. This study will only focus on the B40 group with a median income of RM3,860.  Microtakaful is a kind of takaful product entailed for addressing the financial needs of households with low incomes in times of significant expenses. The main objective of this study was to examine the factors influencing the awareness of microtakaful development among the low-income group (B40). This study examines the relationship between (i) income level (ii) knowledge, and (iii) loss of exposure to the awareness of microtakaful. Data was collected by distributing 320 questionnaires to the residents in (PPR) Kerinchi Lembah Pantai, Kuala Lumpur. Based on the findings, it can be concluded that the three independent variables, namely income level, knowledge, and loss exposures, have a strong positive relationship with microtakaful awareness. However, it is found that income level has the biggest impact on the awareness of microtakaful

Pressure drop in pulsed extraction columns with internals of discs and doughnuts

A study on the pressure drop in pulsed extraction columns with internals of immobile discs and rings, usually called Discs and Doughnuts Columns (DDC) is carried out. The local pressure at a desired level of the column is obtained by resolving of turbulent flow model based on Reynolds equations coupled with k–ε model of turbulence. Consequently, the pressure drop for a column stage or for a unit of column length is determined. The results are used for development of correlations for determination of pressure drop as a function of plate free area, interplate distance and pulsation parameters - amplitude and frequency. Good correspondence to experimental data is observed. The developed quantitative relations are useful for non-experimental numerical optimization of stage geometry in view of lesser energy consumption
