abdominal wall hernia is common but reliable scientific data about its work relatedness is very limited and inconsistent. in this paper, a less common type of abdominal wall hernia in a 30 year old male worker is presented with recurrence after first surgery when he returned to work. in contrast with almost all kinds of hernia, a lifelong limitation for heavy lifting was recommended. it seems t...

Motion in the microcosm unfolds via the formation of wavepackets, resulting from a coherent superposition of quantum states. Pioneered by A. H. Zewail, nuclear motion in (bio-)molecules as well as the formation and rupture of chemical bonds have been accessed extensively by femtosecond (1 fs = 10 seconds) pump-probe spectroscopy. For these outstanding experiments, A. H. Zewail was awarded the N...

Near-synonyms are words that mean approximately the same thing, and which tend to be assigned to the same leaf in ontologies such as WordNet. However, they can differ from each other subtly in both meaning and usage—consider the pair of near-synonyms frugal and stingy— and therefore choosing the appropriate near-synonym for a given context is not a trivial problem. Early work on near-synonyms w...

Background: Nurses play an important role in the healthcare system and constitute the highest number of healthcare workers. A positive attitude or a positive state of mind at work may increase the ability to carry out the organization's duties, tasks and plans. The aim of this study was to investigate the relationship between work effectiveness and work engagement of nurses working in the selec...

rivers can be contaminated with different pollutants such as trout farms. evaluation of the effect of trout farm on water quality is important to give new permission for trout farm construction. in current work, the effect of constructed trout farms near the deinachal river on some physicochemical properties namely chemical oxygen demand (cod), biological oxygen demand (bod5), dissolved oxygen ...

in this work, a novel zr02+ pvc-based membrane sensor based on 4,7,13,16,21,24-hexa oxa-1,10- diazabicyclo[8,8,8]- hexa cosane (hodbhc) as a new ionophore is presented. the sensor displays a linear dynamic rangebetween 1.0x 10-1 and 1.0x10 6 m, with a near nernstian slope of 29.9 ± 0.4 mv per decade in an acidic solution(ph=1). the limit of detection is 8.0 x 1 0 7 m. the electrodes possess adv...

Near-synonyms are words that mean approximately the same thing, and which tend to be assigned to the same leaf in ontologies such as WordNet. However, they can differ from each other subtly in both meaning and usage—consider the pair of nearsynonyms frugal and stingy—and therefore choosing the appropriate near-synonym for a given context is not a trivial problem. Initial work by Edmonds (1997) ...

Examining the cooling rate using impingement of air jet finds a wide application in electronic packaging and micro-scale fluid heat interaction systems, While the prediction of Nusselt profile at low nozzle-target spacing is a big issue. The plot of area average Nusselt number magnitude against the nozzle-target spacing (Z/d) shows a gradual decrement in the profile upto Z/d = 1 and beyond that...
