Agricultural extension, as an informal educational system, is one of agricultural development tools that lean on human capitals. Inefficiency of public bureaucracy on the one hand, and managerial problems on the other hand, as well as neglecting real needs of beneficiaries in planning, have determined responsible to transfer administrative tasks to the private sector and reduce government''s te...

As we have seen, the naive use of classes, in particular the connection between concept and extension, led to contradiction. Frege mistakenly thought he had repaired the damage in an appendix to Vol. II. Whitehead & Russell limited the possible collection of formulas one could use by typing . Another, more popular solution would be introduced by Zermelo. But first let us say a few words about t...

these days, promotion of farmers' technical-scientific abilities in agriculture is one of the main challenges in this sector. agricultural extension as a motivate power source in agricultural development can be more effective in solving these problems via acceptance of responsibility in the educational concepts. but it faces numerous obstacles because of absence of a proper informational s...

The resonant frequency and sensitivity of an atomic force microscope (AFM) cantilever with assembled cantilever probe (ACP) have been analyzed and a closed-form expression for the sensitivity of vibration modes has been obtained. The proposed ACP comprises an inclined cantilever and extension, and a tip located at the free end of the extension, which makes the AFM capable of topography at sidew...

The study analyzed farm management extension services (FMESs) performed by the extension agents of Agricultural Development Projects in South West Nigeria. Study representatives were sampled randomly from Oyo ADP, Osun ADP and Ekiti ADP, making a 50% representation of the South-West. A proportionate sample of 80% of the total of the extension agents in each of the 3 case studies was randomly se...

The "parameter-free", "local effects" theory of Scholz and Kraft is an extension to mammalian cells of the theory of RBE for dry enzymes and viruses of Butts and Katz. Its claim for parameter freedom has been challenged elsewhere. Here we examine its conceptual base and find errors in its use of the physical concept of cross section and its neglect of the radiobiological relationship between ta...

Cervical spine injuries associated with three-point fixation lap-sash seat belts result from impact against the sash. While such injuries are infrequent and often without serious neurologic sequelae, they may produce serious deficits with grave injuries. Flexion-extension fractures of the lower cervical vertebrae, fractures of the transverse and spinous processes of the lower cervical and upper...

Aiming at the channel damage problems of multi-core fiber (Multi-core Fiber, MCF), AKNN (Adapted K-Nearest Neighbor) algorithm is proposed. The MATLAB software was used to simulate seven-core fiber, both inter-core crosstalk (Crosstalk, XT) and nonlinear effects were considered. Then KNN adapted equalize damaged signal receiver. simulation results show that possesses better BER performance lowe...
