BACKGROUND Informed consent in research is partly achieved through the use of information sheets. There is a perception however that these information sheets are long and complex. The recommended reading level for patient information is grade 6, or 11-12 years old. AIMS To investigate whether the readability of participant information sheets has changed over time, whether particular study cha...

PURPOSE In the present study collagen sheets were prepared from the spongy part of the bovine femur and characterized from the physicochemical point of view. METHODS The physicochemical properties of the collagen sheets were studied using scanning electronic microscopy (SEM) and thermogravimetrical analysis (TGA). RESULTS The SEM studies showed that the collagen sheets are porous and exhibi...

The Euler equations that describe geodesics on the group of diffeomorphisms of the plane admit singular solutions in which the momentum is concentrated on curves, the so-called momentum sheets analogous to vortex sheets in the Euler fluid equations. We study the stability of straight and circular momentum sheets for a large family of metrics. We prove that straight sheets moving normally to the...

OBJECTIVE To analyze the cytologic findings of sclerosing adenosis of the breast. STUDY DESIGN We reviewed the fine needle aspiration (FNA) cytologic slides of 7 cases of sclerosing adenosis of the breast and compared the cytologic findings with those of 10 cases of fibroadenoma and 7 cases of fibrocystic change. RESULTS The smears of sclerosing adenosis were moderately to markedly cellular...

Fiber reinforced polymer (FRP) has been used in the construction industry because of its advantages such as high strength, light weight, corrosion resistance, low density and elasticity. This paper presents a review bonding techniques adopted to strengthen timber beams using FRP achieve larger spans. Different methods between have summarized with focus on influencing factors their effects well ...

A common concern regarding cooperative spectrum sensing (CSS) schemes is the occupied bandwidth and the energy consumption during the transmissions of sensing information to the fusion center over the reporting control channels. This concern is intensified if the number of cooperating secondary users in the network is large. This article presents a new fusion strategy for a CSS scheme, aiming a...

The author has developed an application in MATLAB implementing concatenative sound synthesis (CSS) using feature matching. CSS is a process of combining short pieces of recorded sound to construct new sonic forms. Historically, CSS was developed for text-tospeech synthesis, but recently it has been explored as a musical sound synthesis method. The results have been called ‘musaics,’ the sonic a...

According to the financial accelerator model, a small monetary or other shock is amplified through credit market restrictions on small firms, and swings in balance sheets over the business cycle cause swings in small firms’ spending. This paper incorporates these notions in an empirical model of firm behavior. We use unit transaction cost of debt and rationed credit as indicators of balance she...

Inspired by Vygotsky’s Sociocultural Theory (SCT), the current study intended to investigate the effect of summary training (i.e., oral and written) on intermediate EFL learners’ reading comprehension in different conditions (i.e., individual and collaborative). Data collection tools and procedures encompassed PET test, First Certificate in English (FCE) reading pre-test, and post-test. First, ...

The purpose of a Safety Data Sheet (SDS), formerly known as Material Safety Data Sheets (MSDS), is to provide information on the hazards of working with a chemical and procedures that should be used to ensure safety. State and Federal law require that employers obtain an SDS for each hazardous substance they use or store and make the SDS available to employees. The PI/instructor is responsible ...
