highly prevalent in community dwelling older adults in many countries; however,
the prevalence of sarcopenia in nursing home older residents is
not well characterized. The aim of this study is
to assess the prevalence of sarcopenia in nursing home older residents in Cairo. Cross sectional
study was performed among 357 nursing home residents in Cairo. The European Working Group on Sarcopenia in Older
People (EWGSOP) recommendation was used for diagnosing sarcopenia. The study
showed that the prevalence of sarcopenia in nursing home older residents in Cairo was 17.7%, 22.2%
in elderly men and 14.4% in elderly women. Age, underweight and lack of physical activity were
found to be associated with sarcopenia among studied participants. The study concluded that sarcopenia is an emerging health problem in nursing home older residents in Cairo.
Recently, a paradigm of
river restoration is recognized as the importance of flood plan involving abandoned channel.
Hence, effort which abandoned channel area by improvement project will become
the territory of river area is trying. This study is a part of river
restoration project. In this study, hydraulic model experiment and numerical
simulation were performed to understand the flow characteristic and bed change
for abandoned channel restoration. The target area of the hydraulic model was
the midstream of the Hampyeong Stream (stream length: 1.3 km). Horizontal scale
was 1/50 and vertical scale was 1/40. For numerical simulation, the FESWMS
model was used. Cases of hydraulic and numerical models were frequency flood
discharge (50 and 100 years) and channel formation discharge (100 m3/s
and 120 m3/s). Flow characteristics were analyzed in fixed condition
using hydraulic and numerical models. Bed change on abandoned channel
restoration was analyzed on deposition trend using sediment supply from upstream in hydraulic
model, and was compared with results of bed shear stress in numerical model.
Results velocity profile and bed shear stress of numerical model were similar
with trends of measured velocity and deposition of hydraulic model. The results
of this study will be applied to restoration design of abandoned channels.
Quarries are places of high instability due to blastings, if left without rehabilitation they become sites of great risk of rockfall, which are the case of the Carian quarry, a small abandoned aggregate quarry, which turned into a slum neighborhood in the north western part of the city of Tétouan, and that has a long history of rockfall incidents since it was shut down in the 60’s. Using rockmass characterization techniques, kinematic study and stability analysis, it was confirmed that many instability mechanisms are found on the walls of the quarry and cause a high risk of rockfall during the rain season, especially that the study area is inhabited. Rockfall trajectory modelling techniques allow the calculation of vertical distribution of rocks falling from the quarry’s walls along different profiles in the area and therefore the determination of a safety perimeter from the quarry wall.
