the study of air infiltration into the buildings is important from several perspectives that may be noted to energy and design of hvac systems, indoor air quality and thermal comfort and design of smoke control systems. given the importance of this issue, an experimental and numerical study of air infiltration through conventional doors and windows has been explored in iran. to this end, at fir...
in order to determine the effect of irrigation interval and mulch on growth of olive an experiment was carried out in dallaho olive research station at sarepole. a split plot experiment was used based on a completely randomized design with three replications and two factors (mulch and irrigation interval). each experiment unit consists of 4 trees. land preparation was done in february 2005 in a...
INTRODUCTION Vertical jumps have been fully studied during the last thirty years. Especially maximal vertical jumps used to be analyzed, which maximal vertical jump height was considered as the main factor of the performance. Maximal vertical jump height depends on effective energy, the sum of potential and “vertical kinetic energy” (i.e. kinetic energy due to vertical velocity) of the body mas...
No trunk support (NTS) was compared to a lower trunk support (LTS) of leaning against a worktable and a dynamic upper trunk support (UTS) using postural kinematics, trunk extensor muscle activity and subjective rating of both comfort and effort. Ten females completed 3 repetitions where they lifted 0 and 5 kg load from a symmetrical position at hip-height to a 45° asymmetric position at: i) hip...
CONTEXT Because anterior cruciate ligament (ACL) injuries can occur during deceleration maneuvers, biomechanics research has been focused on the lower extremity kinetic chain. Trunk mass and changes in trunk position affect lower extremity joint torques and work during gait and landing, but how the trunk affects knee joint and muscle forces is not well understood. OBJECTIVE To evaluate the ef...
this thesis is going to delineate the concept of the reader as implied in 18th century literary theory; based on the study of the major reader oriented elements of criticism of the age-taste, the sublime, and aesthetic pleasure-its aim is to explain what sott of reader is implied and what kind of response on the part of the reader is proposed in 18th century english literary theory and aestheti...
[Purpose] This study was aimed at investigating the influence of seat height and body posture on the activity of the superior trapezius and longissimus muscles. [Subjects and Methods] Twenty two healthy subjects were instructed to perform a total of eight different body postures, varying according three main factors: seat height (low and high seat); trunk inclination (upright and leaning forwar...
abstract this study evaluates the iranian pre-university english textbook in terms of needs, objectives, content, and methodology. the study was designed on the qualitative- quantitative survey basis using interviews and questionnaires, a researcher-made textbook evaluation checklist and a needs analysis questionnaire. the textbook evaluation questionnaire was used in this study to elicit the ...
BACKGROUND Short stature or short legs is associated with cardiometabolic disease. Few studies have addressed this issue in children, incorporated repeated measures, or studied modern cohorts. METHODS We examined if change in total height, leg length and trunk length between two time points from early (median: 3.2 years) to mid-childhood (median: 7.7 years), with and without adjustment for co...
