diabetes is considered as a global affecting disease with an increasing contribution to both mortality rate and cost damage in the society. therefore, tight control of blood glucose levels has gained significant attention over the decades. this paper proposes a method for blood glucose level regulation in type 1 diabetics. the control strategy is based on combining the fuzzy logic theory and si...

Friction measurement is one of important and interesting problems in the study of handle properties of fabrics. Different methods have been developed for measuring friction, such as sliding, KES and cyclic testing method. In this research, considering the possibilities of varying conditions in measuring friction, a new instrument by which the bottom surface of fabric can be moved and the top sl...

landslides are natural disasters that annually inflict great damages to public and private properties which may associate with loss of life. in recent decades, research on developing methods for predicting the time of landslide has been one of the significant attempts made by scientists. since in some type of material, landslides are preceded by undetectable movements that cannot be recorded an...

Generating the complex waveforms characteristic of beating eukaryotic cilia and flagella requires spatial regulation of dynein-driven microtubule sliding. To generate bending, one prediction is that dynein arms alternate between active and inactive forms on specific subsets of doublet microtubules. Using an in vitro microtubule sliding assay combined with a structural approach, we determined th...

Neurons develop from small, spherical precursors into the largest, most asymmetric of all metazoan cells by extending thin axonal processes over enormous distances. Although the forces for this extension have been unclear, recent work shows that the initial axonal extension may involve an unexpected mechanism: sliding of microtubules, driven by a motor protein previously thought to be deployed ...

We highly purified the Chlamydomonas inner-arm dyneins e and c, considered to be single-headed subspecies. These two dyneins reside side-by-side along the peripheral doublet microtubules of the flagellum. Electron microscopic observations and single particle analysis showed that the head domains of these two dyneins were similar, whereas the tail domain of dynein e was short and bent in contras...

Eukaryotic flagella and cilia have attracted the attention of many researchers over the last century, since they are highly arranged organelles and show sophisticated bending movements. Two important cytoskeletal and motor proteins, tubulin and dynein, were first found and described in flagella and cilia. Half a century has passed since the discovery of these two proteins, and much information ...

this paper presents a gaussian radial basis function neural network based on sliding mode control for trajectory tracking and vibration control of a flexible joint manipulator. to study the effectiveness of the controllers, designed controller is developed for tip angular position control of a flexible joint manipulator. the adaptation laws of designed controller are obtained based on sliding m...

Using a dark-field microscope equipped with a high-efficiency TV camera including a video tape-recorder, we recorded the sliding movement between outer doublet microtubules of the demembranated axonemes of sea-urchin (Pseudocentrotus depressus and Hemicentrotus pulcherrimus) sperm flagella by adding ATP and trypsin at 25 degrees C. The time and length of the sliding doublet microtubules from ax...

Flagellar movement is caused by the coordinated activity of outer and inner dynein arms, which induces sliding between doublet microtubules. In trypsin-treated flagellar axonemes, microtubule sliding induced by ATP is faster in the presence than in the absence of the outer arms. To elucidate the mechanism by which the outer arms regulate microtubule sliding, we studied the effect of trypsin-dig...
