MATERIALS AND METHODS This was a cross-sectional study including 50 palm tree garden workers and a control group of 50 office employees. Data collection included demographics,...

The accuracy of MLC positions during radiotherapy is important as even small positional deviations can translate into considerable dose delivery errors. This becomes crucial when radiosensitive organs are located near the treated volume and especially during IMRT, where dose gradients are steep. A test commonly conducted to measure the positional accuracy of the MLCs is the Picket Fence test. I...

We conducted experiments with behavioral conditioning of white-tailed deer (Odocoileus virginianus) using verb 3-wire, electrified fencing modified with either an attractant or a repellent in order to test the idea that an attractant or repellent coupled with an electric shock, would be a more effective deterrent than a random shock or no shock at all. Exclosures measuring 6 x 6 m with 3 wires ...

BACKGROUND Studies of elderly patients with Garden-I and Garden-II femoral neck fractures (FNFs) suggest that a preoperative posterior tilt of the femoral head of at least 20° increases the risk of fixation failure. A recently published treatment algorithm recommended hemiarthroplasty over internal fixation for elderly patients with Garden-I and Garden-II FNFs and a preoperative posterior tilt ...

In a poem titled “Fence or Ambulance” written more than one hundred years ago, Joseph Malins described the policy dilemma a city faced in tackling the rising morbidity and mortality from accidental falls from a dangerous cliff. The 2 policy options considered included building a strong fence around the edge of the cliff or raising funds to support an ambulance down in the valley. The city initi...

Excessive sedimentation derived from anthropogenic activities is a main factor in habitat and biodiversity loss in freshwater ecosystems. To prevent offsite movement of soil particles, many environmental regulatory agencies mandate the use of perimeter silt fences. However, research regarding the efficiency of these devices in applied settings is lacking, and fences are often ineffective due to...
