abstract growth retardants are new chemical organic compounds that increase period of flowering, leave chlorophyll, lateral shoot number, flower number and decrease vegetative growth. they also increase dry, cold and heat tolerance. paclobutrazol and cycocel are examples of these compounds. this study was conducted to evaluate the effect of paclobutrazol and cycocel on some quantitative and qua...

background hyperactivity of depressor septi nasi muscle leads to smiling deformity and nasal tip depression. lateral fascicles of this muscle help in widening the nostrils. the purpose of this study was to evaluate the relationship between the nasal length changes and the alar base and the alar flaring changes during smile. methods standard photographs are performed in the face and lateral view...

Rigid monopiles with small slenderness ratios (i.e., ratio of monopile embedded length to outer diameter) are widely used as foundations resist lateral load and moment transferred from superstructures, e.g., large diameter steel pipes by offshore wind turbines piers in electric utility industry or sound barriers. A design model for laterally loaded rigid cohesive soil is presented this paper. T...

Segmental kinematics were investigated in horses during overground locomotion and compared with published reports on humans and other primates to determine the impact of a large neck on rotational mobility (> 20 deg.) and stability (< or = 20 deg.) of the head and trunk. Three adult horses (Equus caballus) performing walks, trots and canters were videotaped in lateral view. Data analysis includ...

STUDY DESIGN Twenty healthy volunteers were subjected to left lateral impacts, randomly looking either left or right. OBJECTIVES The purpose of this study is to determine the response of the cervical muscles to lateral impact whiplash-type perturbations when the head is rotated at the time of impact. SUMMARY OF BACKGROUND DATA A previous study of left lateral impacts with head in neutral po...

Two new species of Hymenocephalus are described from the New Zealand region and Tasman Sea. Hymenocephalus fuscus sp. n. has 11-12 pelvic fin rays, is darkly pigmented, with enlarged bony ridges on the dorsal aspects of head, lacks a chin barbel, has few (16-19) gill rakers on inner side of first arch and is similar to other species in the H. aterrimus species group. Hymenocephalus maculicaudus...

Root formation and root architecture of olive microshoots, inoculated or not with Pseudomonas fluorescent P19 or P21, were evaluated by measuring of length and the numbers of adventitious and lateral roots. Three-four nodal in vitro shoots were treated with different population densities (0, 105, 108 CFUml-1) of rhizobacteria. The density of 108 CFUmgl-1 induced almost two times increase in num...

The type 1 ryanodine receptor (RyR1) mediates Ca2+ release from the sarcoplasmic reticulum to initiate skeletal muscle contraction and is associated with muscle diseases, malignant hyperthermia, and central core disease. To better understand RyR1 channel function, we investigated the molecular mechanisms of channel gating and ion permeation. An adequate model of channel gating requires accurate...
