Elastic mechanisms are fundamental to fast and efficient movements. Mantis shrimp power their fast raptorial appendages using a conserved network of exoskeletal springs, linkages and latches. Their appendages are fantastically diverse, ranging from spears to hammers. We measured the spring mechanics of 12 mantis shrimp species from five different families exhibiting hammer-shaped, spear-shaped ...

The objective of this study was to focus the light on the events of angiogenesis during spring and summer times. For this purpose, testes of ten rams were collected from Baghdad in spring and summer seasons in 2017.Samples were histologically processed and prepared for light microscopy. Hematoxylin and eosin stain was used for staining. The results revealed that the process of angiogenesis was ...

BACKGROUND Despite of the widepread use of Pilates in Physical Therapy, there are few studies that have assessed the muscle electrical activation during Pilates exercises. OBJECTIVE Verify the influence of different spring adjustments and individual positions on the electrical activation of multifidus (MU) and oblique external (OE) muscles during hip flexion-extension (HFE) exercise on the Ca...

Both the linear leg spring model and the two-segment leg model with constant spring stiffness have been broadly used as template models to investigate bouncing gaits for legged robots with compliant legs. In addition to these two models, the other stiffness leg spring models developed using inspiration from biological characteristic have the potential to improve high-speed running capacity of s...

Plant diseases are caused by pathogen populations continuously subjected to evolutionary forces (genetic flow, selection, and recombination). Ascochyta blight, caused by Mycosphaerella pinodes, is one of the most damaging necrotrophic pathogens of field peas worldwide. In France, both winter and spring peas are cultivated. Although these crops overlap by about 4 months (March to June), primary ...

late spring frost usually damages flowers and reduces yield of almond trees. due to natural sexual reproduction, in most of almond orchards of qazvin province, iran, which have been established through seedling propagation, a vast genetic variation has been occurred. this situation has been provided many possibilities to study different traits of native almond genotypes, to select superior geno...

JCO/JANUARY 2003 F devices are increasingly being used for molar distalization in Class II treatment because they eliminate the need for special patient compliance. These appliances fall into two main categories: intra-arch (such as the Distal Jet,* Jones Jig,* and Hilgers Pendulum**) and interarch (such as the Herbst*** and active springs). The spring appliances can be further divided into can...

SPRING (http://algorithm.cs.nthu.edu.tw/tools/SPRING/) is a tool for the analysis of genome rearrangement between two chromosomal genomes using reversals and/or block-interchanges. SPRING takes two or more chromosomes as its input and then computes a minimum series of reversals and/or block-interchanges between any two input chromosomes for transforming one chromosome into another. The input of...
