This paper mainly concern on a new methodology of wireless transmitting Electromyography (EMG) signals to myoelectric prosthetic hand which manufactured from 3D printing technology. A Myoelectric controlled prosthesis is an externally powered artificial limb which can control with the electrical signals generated naturally by muscles. Sometimes in case of particular amputees, fetching EMG signals by sensors is not possible from that destructed muscles but, EMG generated from healthy muscles besides that amputees can be used in the transmission of signals. The objective of this research is to generate the new technique for transmitting EMG signals without wire from any adequate healthy muscles. In this methodology, we used the EMG sensor to detect EMG signals, which perform a pre-processing task and featured extraction on EMG............

We report on the production of theophylline fine particles by a new spray drying using supercritical carbon dioxide as an atomizing medium. The powders produced were agglomerates, composed of columnar or platelike primary crystals with a mean size of around 260 nm, which was 270 times smaller than that of the virgin particles. There were no liquid solvents (i.e., residual solvents) in the crystals produced. The crystal structure of the theophylline powders did not change after the micronization by the present technique: it was the kinetically stable form at room temperature, i.e. form II.This processisa versatile process, applicable for several substances, and can be operated at low processing costs due to the relatively low operating pressures, low gas consumption and operation in a continuous mode. Compared with conventional spray dryings, the present technique can also be used at much lower drying temperatures, resulting in less degradation and lower energy consumption.

The causality relation between solar flares and the coronal mass ejections has been thought as that as the coronal mass ejections result from strong solar flares, as far as geomagnetic storms controlled by coronal mass ejections.This study focused on such relation, through statistical analysis by calculating the correlation coefficient between solar flares and (A) index data for (21) years, namely (1996 – 2016).The correlation coefficient calculated for different intervals.The results emphasized the common known fact for long time period, while zooming on shorter intervals revealed that not every strong solar flare creates a coronal mass ejection, and the coronal mass ejections are not the only factor that affects the geomagnetic field.

The estuarine bays in Ebrié lagoon undergo enormous anthropic pressures in addition to the natural pressures. They constitute the main points of completion of suspended materials and solid discharges drained by the sewage system of the city of Abidjan. The bathymetric surveys carried out in Adiopo-Doumé Bay have made it possible to characterize the morphology of the lagoon bottom. Thus the depths vary from 0 to 10.50 m, with an average of 2.50 m. A main channel shoals and depressions stand out. Also the configuration of the main channel highlights three types of channels: the channel type "U" (transport-deposit phenomenon), type "V" (erosiontransport phenomenon) and intermediate type (unstable). This study made it possible to produce the bathymetric map, the map of the slopes and to determine the configuration of the main channel of Adiopo-Doumé bay.

A tractor mounted two-row ridge yam sett planter was developed and its performance evaluated. The main features of the planter are: land wheel, metering device, hopper, opener, coverer and frame. The planters' performance was conducted on the field at tractor forward speeds of (2.8, 3.8 and 5.7) km/h respectively. Parameters determined were the effect of speed on planting distance and depth, evenness of planting, rate of operation and metering efficiency. The physical properties such as size and weight, Impact force of yam setts on the soil were also determined.Results showed that the metering device had 100 % efficiencies for all speeds. The planter had a mean planting distance of 0.9 m with dropping evenness of 92 %. Similarly, average theoretical capacities of (0.14 ha/h), effective field capacities..........

The aim of this survey is to show how the collapse of the underground cavities in the municipality of Bipemba in Mbujimayi is one of the consequences of the evolution of airport facilities which, by disrupting the circulation of runoff water, accelerated the dissolution of the underlying limestone rocks following the intensification of infiltration in depressions where water had accumulated. To prevent and reduce geohazards, the article identifies their different characteristics and suggests some remedies...

The accuracy of hydrocarbon reserve estimation rest largely on the quality of the generated field geologic model as well as how frequently the model is updated with new knowledge. The acquired data from the multinational oil company were quality checked. Different logs were investigated across the field using Gamma Ray and Resistivity log signatures. Sand bodies were investigated across the field after which they were correlated. Horizon and fault mapping were carried out on the seismic data, after which the structural modeling continued with the layering and zonation process. The thickness of the sand bodies ranged from 42ft to 173ft, and the hydrocarbon saturation ranged from 51% to 79%. The porosity also ranged from 17% to 24%, while the NTG ranged from 27% to 94%. These are fantastic indicators of economic accumulations. The generated model affirmed a growth-fault assisted hydrocarbon accumulation.....

Alumina (Al2O3) based porous ceramic materials are widely used in filters, sealing elements, refractors, and biomaterial applications. Among them, biomaterials have a great attention for artificial bone and filler materials. Hydroxyapatite (HA)is the most preferred calcium phosphate based powders to enhance the biocompatibility of the bioceramics.This study aims to fabricate HA reinforced alumina-based porous ceramics and investigate their mechanical properties. In this study, porous organic sponges were used as foaming template. The foam materials were sintered at different temperatures (TS=1600-1700-1750 °C) for 2 hours. The microstructure of the foam materials was analyzed by scanning electron microscopy (SEM). The compressive strength of foams was determined......

In this study, porous calcium phosphate (CaP) based bioceramics in hydroxyapatite (HA) and tricalcium phosphate (TCP) form was fabricated for bone graft and porous orthopedic applications. Metal ion doped CaP based powders in HA structure were synthesized by wet chemical methods for pH5.5 and pH8.5. All shaped ceramics were sintered between at1100-1300°C for 1-3 h to possess porous structure. The microstructure and phase formation of the porous ceramics were characterized by X-ray diffraction (XRD) device and scanning electron microscopy (SEM). Depending on the sintering temperature and synthesized pH, the compressive strength of the porous ceramics was tested by the universal test machine. In conclusion, the HA structures were transformed to tricalcium phosphate (TCP) phase for pH5.5 at 1100°C. The synthesized powder for pH8.5 preserved its hydroxyapatite structure for all sintering temperatures. The highest compressive strengths of TCP and HA bioceramics for pH5.5 and pH8.5 were measured as 17.6 and 20.3 MPa at 1200°C and 1300°C, respectively.......

The purpose of this study was to obtain a design of the Hemi Savonius windmill model that is related to construction information, functions and characteristics as a wind energy conversion system. The design results are used to complement the windmill techno park facilities in the context of developing integrated tourism education. The construction of the energy conversion system is a modification of the basic model of the Savonius windmill rotor, which consists of two rotors with 6 (six) leaf blades, which are arranged in a multilevel opposite or referred to as a Multilevel Blades Hemi Savonius Windmill model. The rotor blades are planned by splitting into two parts, the same as the Savonius ferrite rotor blades. The test results on the model were carried out in the Laboratory, while the prototypes in the field, which showed the performance of the windmill, were quite reliable as wind energy conversion systems. Through the results of data analysis, it is known that the ability of this wheel to extract kinetic energy at an average velocity of V = 2.8 m/sec achieves rotor efficiency of 51.4% with a rotation of 34.6 rpm and electrical voltage........
