Effects of gravitational loading or unloading on the growth-associated increase in the cross-sectional area and length of fibers, as well as the total fiber number, in soleus muscle were studied in rats. Furthermore, the roles of satellite cells and myonuclei in growth of these properties were also investigated. The hindlimb unloading by tail suspension was performed in newborn rats from postna...

due to the considerable growth in the worldwide container transportation, optimization of container terminal operations is becoming highly needed to rationalize the use of logistics resources. for this reason, we focus our study on the quay crane scheduling problem (qcsp), which is a core task of managing maritime container terminals. from this planning problem arise two decisions to be made: t...

Three experiments, each using 280 pigs, were conducted in a simulated compartment to test the effect of angle of entrance (AOE) to the ramp (90°, 60°, 30°, or 0°), ramp slope (0°, 16°, 21°, or 26°), and an initial 20-cm step associated with 16° or 21° ramp slopes on the ease of handling, heart rate (HR), and behavior of near market-weight pigs during unloading. Heart rate (pigs and handler), un...

This paper presents a research framework on loading and unloading process for inter terminal transfer (ITT) operation. Container movement in the transport industry depends on the service provided in the terminal. The complexity of the activities in the process could possibly contribute to potential delays occurred. In this paper, Petri Nets (PN) is introduced as new approach in modeling the con...

Of nine plant growth regulators (indoleacetic acid, 1-naphthalene acetic acid, gibberellic acid, giberellin 4/7, 6-benzylaminopurine, 6-furfurylaminopurine, abscisic acid, and 1-aminocyclopropane carboxylic acid) tested, only 6-benzylaminopurine and abscisic acid affected (14)C-photosynthate unloading from excised seed coats of Phaseolus vulgaris L. Unloading, in the presence of KCl, was stimul...

In recent years, the scale of container transportation and the size of vessels are becoming larger and larger; development of automatic container cranes becomes a necessity. As a key function of automatic control of unmanned cranes, the optimum route can minimize the cycle time by calculating the most efficient combination of horizontal and vertical motions of container loading/unloading. In th...

The present study was performed to investigate the effect of commercial and operational factors on competitiveness improvement of Shahid Beheshti Port (SBP) in Chabahar in attracting shipping lines. The research method is applied in terms of purpose. Initially, the researcher conducted the qualitative phase to identify important variables, create a typology, or make new theories. To reach the s...

Background Ability of balance maintenance and postural control is important to prevent falling and injuries when balance perturbations occurs during walking. Injuries due to unloading of the base of support in walking and running such as ankle sprain has high incidence. Poor muscle function may put the joint in unstable condition. The association of the unloading and poor muscle function in the...

Seedlings of Arabidopsis thaliana were used to assess its recovery ability, DNA methylation alteration and exchanges after cryopreservation. The survival rate and the level of DNA methylation were evaluated after pre-treatment (loading and cryoprotection), unloading and recovery from cryopreservation of the plants. Over 98% of the plants were survived after pre-treatment and unloading without c...

Abstract. A new approach to irreversible quasistatic fracture growth is given, by means of Young measures. The study concerns a cohesive zone model with prescribed crack path, when the material gives different responses to loading and unloading phases. In the particular situation of constant unloading response, the result contained in [6] is recovered. In this case, the convergence of the discr...
