BACKGROUND Tunnel enlargement is frequently seen in short-term follow-up after anterior cruciate ligament reconstruction (ACLR). According to new evidence, tunnel enlargement may be followed by tunnel narrowing, but the long-term evolution of the tunnels is currently unknown. HYPOTHESIS/PURPOSE The hypothesis was that tunnel enlargement is followed by tunnel narrowing caused by ossification a...

A combination of room cooling and the use thermal insulation materials to maintain okra quality under simulated storage transportation was evaluated. Okra pods were packed in plastic baskets either cooled at 18 °C or not a for 2 h. After no cooling, covered with three different materials: (1) perforated linear low-density polyethylene (P-LLDPE), (2) two layers heat-reflective sheet thin nonwove...

The membrane properties of isolated frog parathyroid cells were studied using perforated and conventional whole-cell patch-clamp techniques. Frog parathyroid cells displayed transient inward currents in response to depolarizing pulses from a holding potential of -84 mV. We analyzed the biophysical properties of the inward currents. The inward currents disappeared by the replacement of external ...

anatomical vascular variations are rare causes of carpal tunnel syndrome. an aberrant medial artery is the most common vascular variation, while an aberrant radial artery causing carpal tunnel syndrome is even more rare, with an incidence ranging less than 3%. this article reports a patient with compression of the median nerve at the carpal tunnel by an aberrant superficial branch of the radial...

Introduction: Micro-perforated absorbents are one of the structures that are widely used nowadays. The sound absorption mechanism is performed by viscous energy losses in the cavities on the plate. In this study, the acoustic properties of non-flat perforated panels in oblique angle was investigated in numerical method. Material and Methods: This paper examined the effect of the surface shape ...

In this study, the seismic interaction of surface foundations and underground cavities was investigated. For this purpose, a parametric study of geometric dimensions of the foundation and cavity, their location, and the effect of the interaction between surface foundations and underground cavities was evaluated. The variable parameters include the ratio of the overburden height to the foundatio...

BACKGROUND Enhanced recovery pathways are now widely used in elective surgical procedures. The feasibility of enhanced postoperative recovery pathways in emergency surgery for perforated peptic ulcer disease was investigated in this randomized controlled clinical trial. METHODS Patients with perforated peptic ulcer disease who underwent laparoscopic repair were randomized into 2 groups. Group...

the selection of optimum support system is a key step in the successful design operation of tunneling, rock mass stabilization and minimization of plastic zone extension around a tunnel. in this context, it is not sufficient to rely only on the experiences of design engineers, but taking all effective measures and parameters is necessary to do a proper choice. in this paper, multi attribute dec...

Qomroud water conveyance tunnel (lot 1&2) with the length of 16 kilometers is considered as one of the greatest development and national projects in Iran. Since about 2 kilometers of tunnel pass through alluvium and the rest of the tunnel pass through various types of geological units, and due to the complexity of geological condition and variety of effective criteria, suitable selection of exc...
