The radiographer is one of the most important and needful components of the workforce in the health care system. This study aimed to investigate the prevalence of depressive symptoms and explore its associated risk factors among radiographers working in the West Bank hospitals. A cross-sectional design was used for the study. Beck's depression inve...

In this review, the flow phantoms and the wall‑less flow phantoms with recognized acoustic features (attenuation and speed of sound), interior properties, and dimensions of tissue were prepared, calibrated, and characterized by Doppler ultrasound (US) scanning which demands tissue‑mimicking materials (TMMs). TMM phantoms are commercially available...
Article
Abstract:Some researchers formerly provided the mechanical, physical, and attenuation properties of the fabricatedEremurus–Rhizophoraspp. particleboard phantom. In this study, the percentage depth dose (PDD) and the half value layer(HVL) of fabricatedEremurus–Rhizophoraspp. particleboard phantom were determined and compared with those ofPerspex and...

Aim: The aim of this study was to compare objective image quality data for patient pulmonary embolism between a conventional pulmonary CTA protocol with respect to a novel acquisition protocol performed with optimize radiation dose and less amount of iodinated contrast medium injected to the patients during PE scanning. Materials and Methods: Sixty...

Full-text available
The roots of Eremurus spp. were used as a bio-adhesive in the fabrication of Rhizophora spp. particleboards. The mass attenuation coefficients of Eremurus–Rhizophora spp. particleboard of six samples with two different weight percentages of the Eremurus spp. root (6% and 12%) and three various Rhizophora spp. particle sizes (≤149 µm, 149–500 µm and...
Article
Full-text available
Gum Arabic (GA) was used as a binder for the fabrication of Rhizophora spp. particleboards. The physical and mechanical properties of the bioadhesive bonded particleboards, including moisture content, internal bond (IB) strength, thickness swelling (TS), water absorption (WA) and field-emission scanning electron microscopy (FESEM) were used to char...
Article
Full-text available
In this study, some characteristics of Rhizophora spp. particleboards bonded with Serishoom (traditional animal–based adhesive) as a phantom material was investigated. The Rhizophora spp. particleboards were fabricated in two Serishoom adhesive treatment levels (6% and 12%) with three Rhizophora spp. particle sizes (≤ 149 µm, 149 µm – 500 µm, and 5...
Article
Full-text available
For the first time, Gum Arabic (GA) is used as a binder in particleboards preparation and the attenuation properties of the fabricated particleboards were evaluated to check their suitability as tissue equivalent material. Gum Arabic was added into Rhizophora spp. particleboards of four particle sizes at three different GA adhesive levels. The X-ra...
Article
Full-text available
In this study, the green animal-based, which has been prepared by prolonged boiling of the inedible connective tissues of domesticated ungulates, was investigated for adhesive properties. The viscosity of green animal-based wood adhesive was measured and compared with that of urea-formaldehyde (UF) and phenol-formaldehyde (PF) which are widely used...
Article
Full-text available
The objective of this study is to evaluate the mechanical and physical properties of the particleboard manufactured from Rhizophora spp. in three particle sizes bonded with powdered Eremurus spp. root as a bio-based adhesive in two adhesive treatment levels. The samples acquired high internal bond strength values when the Rhizphora spp. particle si...

Never before, gum Arabic (GA) has been used as a bio-adhesive in particleboard manufacturing. For the first time, GA is used in this study as a binder in Rhizophora spp. particleboards. The fabricated particleboards were evaluated in terms of field emission scanning electron microscopic (FESEM) surface features and carbon, hydrogen, nitrogen, and s...

As with many cities all over the world with active industrial developments, the city of Penang in Malaysia has also the potential of being exposed to industrial pollution. Such exposure would certainly have a detrimental impact on the environment and the people. The determination of trace elemental levels in hair which is well known as a method for...
Article
Full-text available
The laser-skin interaction was studied using the laboratory albino rat skin as an experimental sample and 10.6 μm wavelength CO 2 laser as a source of irradiation. This study aimed to determine the effect of different laser doses on the skin structure as a trial to understand how laser exerts its medical effects in treating skin problems. It also a...
