The increase use of technology in daily life needs the development of leaning media which utilizes technology as well. The use of mobile phones is increasing among students and the use of inappropriate makes the device as a medium of entertainment. It needs a learning media using mobile phones in the form of applications. There is lack of applications with the theme of education in accordance with learning. Mobile phones are not used as learning media by teachers and students. The reverence of learning material and learning media makes research on technology education need to be raised as a matter of matter in the field. The development of the local cultural application of Pasuruan has become one of the mobile interactive learning media that can be used as a medium for learning revision in and outside the school. The development process is carried out through the 4D stages, which are define, design, develop and dessemine. Based on the results of the research, it can be seen that there is the effectiveness of learning to use learning media applications. In addition, the results of the validator shows decent results as products which can be used. The respond of teacher and student show satisfied result in using Pasuruan local culture application as learning media.

The sunflower (Helianthus annus L.) crop has been gaining prominence in wastewater research due to its relevance to the production of edible oil, biodiesel and ornamental and decorative material. In the field of floriculture, the crop has been emerging as an alternative offer of a short-cycle product, with contrasting colors and easy identification by the consumer. The objective of this work was to evaluate the different electrical conductivities of water associated with nitrogen fertigation rates on the vegetative, physiological and productive behavior of ornamental sunflower. The experimental design was completely randomized, in a factorial scheme 6x4, referring to six levels of electrical conductivity of water (ECa of 0.5, 1.5, 2.5, 3.5, 4.5 and 5.5 dS m-1) and four nitrogen fertigation rates, with one control and the other three applications performed every 10, 20 and 30 days after emergence (DAE), with five replications, totaling 120 experimental units. The variables analyzed were: stem diameter, root length, chlorophyll a, b and total chlorophyll content, fresh and dry phytomass of shoots, roots and total phytomass, seed mass and capitulum mass. The salinity negatively affected the physiological variables, growth and productivity evaluated, decreasing with increasing electrical conductivity of irrigation water (dS m-1). Nitrogen fertigation at 10 days after emergence resulted in an increase in the stem diameter of sunflower plants.

This study was conducted to examine whether negative air ions created by anion-fiber would influence the human physiology and psychology. Dynamic continuous blood pressure and electroencephalogram were examined during a 5-h exposure to negative air ions created by anion-fiber in ten adult healthy volunteers. Physiological experiment research was carried out in environmental science laboratory with the anion-fiber curtain. The concentration of negative ions is above 1300 ion/cm3 and the normal standard is 720 ion/cm3.The results suggest that the dynamic continuous blood pressure and skin temperature could possibly be reduced (P<0.01) and the β index of each region decreased significantly.

In this paper, the new bamboo-based consolidated composite floors were fabricated with thin bamboo veneers which used as decoration layers, wear resistant layers, high density fiberboards and equilibrium layers through assembling and scuffing. The effect rules of the composite floor on properties were preliminarily studied by three factors: hot-pressing temperature, pressure and time. The results showed that the wear resistance and surface bond strength of the thin bamboo veneer consolidated composite floor significantly increased with the rise of hot-pressing temperature. In the scope of resources, the effect of hot-pressing pressure and time on properties of the floor is not significant. The optimizing technology is hot-pressing temperature 170°C, pressure 3MPa and time 40s/mm in this study. The thin bamboo veneer consolidated composite floor is an excellent floor decorative material, which has good physical and mechanical properties.

The Mathematical Model

The article analyzes the new temperature - insulative materials. It is motivated that the temperature - insulative material capable to work in the panel as a temperature insulative and facing-decorative material can be only composite type. The composition of the new material, the technology of its production, as well as the mathematical model of the mechanism of formation of strong crusts at its surfaces. The material that is used for the manufacture of roofing panels, panels BKU with an internal non-metallic layer. These panels allow you to break the bridges of cold in butt joints, which improves thermal performance, reliability and durability of the building as a whole. Based on the developed mathematical model, you can predict the properties of foam plastic.

The plaster is used as a flattening of the interior and exterior surfaces of the buildings and as decorative material. In this study, photon attenuation coefficients of barite plaster containing steel were measured. The measurements performed at 511, 835 and 1275 keV which are obtained from 22Na and 54Mn radioactive sources, using a gamma spectrometer that contains a NaI(Tl) detector and MCA. The measured results were compared with the calculation obtained using computer code of XCOM for 1 keV–1 GeV gamma energies. Also, half value layer (HVL) and tenth value layer (TVL) were calculated using the results obtained from the experimental measurement.
