Before And After

Currently, electronic devices are widely used in modern precision farming technology. Soil surface measurement is solved with single-purpose handheld instruments that are placed in the field before passing a tillage machine such as a plow or harrow and after tilling the soil. Laser, photogravimetric and synthetic aperture radar systems are used for non-contact measurement of soil roughness and uniformity. Measurements to calibrate the camera output were carried out at three height levels: 500 mm, 1000 mm and 1500 mm. The indicated measuring heights have been selected for possible applications in agricultural soil research, for example when determining the quality of the treated soil during plowing after passing the tillage machine. Measurements can be used to determine the condition of the soil before and after treatment. The system is easy to use and does not require special and additional expensive software. The use of 3D cameras is effective for determining the state of soil cultivation and a promising direction for adjusting the parameters of the tillage machine.

Precision sowing trend is development of technology of sowing maize. The advantage of planting corn with precision seeder includes saving seeds, fewer working hours, achieves more uniform spacing in the row and depth of planting, and for these reasons it follows that the crop will be uniform in height and strength, which is a prerequisite for high yields. It was performed a field testing of three seed in sowing maize at three different speeds of sowing. Tests were carried out to determine and compare the quality of three planters with under pressure. Seeders worked in similar conditions but third seeder noted presence of crust on the soil surface. They were tested at a speed of 6, 8 and 10 km/h. At a speed of 6 km/h all three planters worked with a coefficient of variation less than 25% and with values ​​from 19.25 to 22.72%, which meets the criteria of quality planting. The percentage of pairwise from 1.66 to 2.64%. The percentage of empty spaces were from 4.24 to 4.93%. Proportion of seeds sown at a given space were from 92.5 to 94.09%, which is an indicator that sowing was successfully. No records are examined quality differences in sowing seed.

Effect Of Copper

Abstract Polycrystalline copper (Cu) foil is widely used as catalytic substrate for graphene growth in chemical vapor deposition (CVD) technique. The surface properties of the Cu foil strongly affect the growth behavior and final quality of CVD-grown graphene. The effect of pretreatment of Cu foil using four different solutions (acetone, acetic acid, HCl and HNO3) on the graphene growth held in atmospheric pressure CVD and its subsequent impact on electrical and optical properties are investigated. Natural camphor is used as the solid carbon precursor. The surface characteristics before and after the growth are studied using scanning electron microscopy and atomic force microscopy. The pretreatment conditions of Cu and the growth of graphene from camphor were correlated using Raman spectroscopy, optical and electrical characteristics. Our findings suggest that HCl pretreated Cu foil exhibited large-domain, uniform coverage of the transferred graphene with excellent optical (> 93% at 550 nm) and electrical properties (sheet resistance of 861 ± 40 ohm/sq), with promisingly low RMS value of roughness (38 nm). The pretreatment process improved the quality of graphene by removing the surface impurity particles and surface native oxides. A Schottky junction diode of graphene/n-silicon is fabricated by transferring the graphene to SiO2/Si substrate under dark and illuminated conditions is also demonstrated to establish its potential in micro- and opto-electronics.

The Impact

Zakat is one of the five pillars of Islam which has a function of faith, social and economic functions. Muslims who can pay zakat are required to give at least 2.5 per cent of their wealth. The problem of poverty prevalent in disadvantaged regions because of the difficulty of access to information and communication led to a gap that is so high in wealth and resources. The instrument of zakat provides a paradigm in the achievement of equitable wealth distribution and healthy circulation. Zakat potentially offers a better life and improves the quality of human being. There is a human quality improvement not only in economic terms but also in spiritual terms such as improving religiousity. This study aims to examine the role of zakat to alleviate humanitarian issues in disadvantaged regions such as Sijunjung, one of zakat beneficiaries and impoverished areas in Indonesia. The researcher attempted a Cibest method to capture the impact of zakat beneficiaries before and after becoming a member of Zakat Community Development (ZCD) Program in material and spiritual value. The overall analysis shows that zakat has a positive impact on disadvantaged regions development and enhance the quality of life of the community. There is an improvement in the average of mustahik household incomes after becoming a member of ZCD Program. Cibest model demonstrates that material, spiritual, and absolute poverty index decreased by 10, 5, and 6 per cent. Meanwhile, the welfare index is increased by 21 per cent. These findings have significant implications for developing the quality of life in disadvantaged regions in Sijunjung. Therefore, zakat is one of the instruments to change the status of disadvantaged areas to be equivalent to other areas.

Introduction: There is a decline in male fertility thus new treatments are needed. Aims: To test the efficacy of a new dietary supplement developed in the USA and registered as a curing drug in Hungary (OGYI). Methods: In a clinical trial 100 men with low sperm quality (spermium count 5–20 M/ml, good motility 10–40%, and adverse shape 30–50%) were examined. Results: Sperm parameters were measured before and after a 3-month treatment and after another 3-month without treatment. This dietary supplement statistically and clinically significantly improved sperm count and motility. In 74 cases this dietary supplement demonstrated a beneficial effect on sperm quality (more than 10% increase in sperm count, or quality of motility, or shape); in 16 cases the improvement exceeded 30%. No adverse effect could be accounted for this treatment. Conclusions: This new dietary supplement may contribute to the treatment of male infertility. Orv. Hetil., 2012, 153, 1787–1792.
