AbstractResearch results on the quality of work of a seed cutter for selected cultivars of sweetcorn were presented. Measurements were carried out at the rotational speed of a head of 1600 rot. min−1 and a linear velocity of the cob conveyor of 0.31 m s−1. A statistically significant relation between the degree of cutting the seed mass and the selected mechanical properties of grain were determined. Differences between cultivars at the level of approximately 43% for the force of perforation of the peri-carp Fp,

Abstract The corrosion scientist and corrosion engineer are complementary; their efforts are synergistic in solving problems of corrosion control. The broad background of a corrosion engineer capable of covering the entire field of corrosion engineering includes knowledge of chemistry, metallurgy, physical, chemical and mechanical properties of materials, electrical engineering, mechanical engineering, biology, stress analysis, economics, human nature and many other fields. The corrosion scientist and corrosion engineer should regard each other with equal esteem, the only basis for evaluating the other's efforts being quality of work.

To improve the mechanical properties of the EDM electrode material, the electroforming process for fabricating copper-nanozirconia (ZrO2) particles composite aided by ultrasonic has been presented. In this research, some vital process parameters such as concentration of ZrO2, rotational speed and ultrasonic frequency have been evaluated. Two inspection criteria, content of ZrO2and micro hardness of deposited layer were employed to evaluate the fabrication quality of copper-nanozirconia (ZrO2) composite material. The experimental results indicate that nanocomposites grains electroformed aided by ultrasonic are refined. Their organizations are more uniform and dense, the surface is flatter and the microhardness of nanocomposites is significantly improved.

There is a shortage of river sand and a large number of phonolite deposits around Nairobi, Kenya, but the quality of manufactured sand made from phonolite is poor. In this paper, the effects of phonolite manufactured sand and river sand on the performance of C30 and C50 concrete are studied through the tests of mixture performance, mechanical properties and durability. The results showed that compared with the concrete prepared with river sand, the dosage required of superplasticizer in the preparation of concrete using phonolite manufactured sand was higher, the fluidity was slightly lower, the mechanical properties were basically unchanged, and the durability was slightly better. The above research results preliminarily indicate that it is feasible to use the manufactured sand produced by phonolite around Nairobi, instead of river sand, to prepare concrete. This will reduce the long-distance procurement and transportation of river sand and reduce project construction costs.

Kinerja perawat merupakan hasil yang dicapai dalam melaksanakan asuhan keperawatan di rumah sakit. Terciptanya asuhan keperawatan yang optimal sangat diperlukan dukungan dari pihak rumah sakit salah satunya adalah menciptakan kualitas kehidupan kerja baik bagi perawat. Penelitian ini bertujuan untuk mengetahui hubungan antara kualitas kehidupan kerja terhadap kinerja perawat pelaksana di RSUD Teluk Kuantan. Jenis penelitian kuantitatif dengan pendekatan cross sectional. Jumlah sampel 120 responden yang diperoleh melalui proportionate simple random sampling. Hasil penelitian menunjukkan kualitas kehidupan kerja perawat RSUD Teluk Kuantan berada pada kategori sedang, kinerja perawat berada pada kategori kurang baik. Berdasarkan analisis kedua variabel teridentifikasi bahwa tidak ada hubungan antara kualitas kehidupan kerja dengan kinerja perawat pelaksana dengan  p value 0,817. Dimensi work context merupakan komponen yang memiliki hubungan dengan kinerja perawat pelaksana dengan p value 0,008, dimensi work life  tidak berhubungan secara signifikan dengan kinerja perawat. Kesimpulan penelitian diketahui tidak ada hubungan antara kualitas kehidupan kerja dengan kinerja perawat pelaksana. Ada hubungan dimensi work context dengan kinerja perawat pelaksana. Tidak ada hubungan dimensi work life dengan kinerja perawat.   Kata kunci: kualitas kehidupan kerja, kinerja, perawat pelaksana   THE RELATIONSHIP BETWEEN THE QUALITY OF WORK LIFE AND THE PERFORMANCE OF IMPLEMENTERS NURSES   ABSTRACT Nurse performance is the result achieved in implementing nursing care in a hospital. The creation of optimal nursing care is very much needed support from the hospital, one of which is to create a good quality of work life for nurses. This study aims to determine the relationship between the quality of work life and the performance of nurses at the Kuantan District Hospital. This type of quantitative research with cross sectional approach. The number of samples of 120 respondents obtained through proportionate simple random sampling. The results showed that the quality of work life of nurses at the Kuantan District Hospital was in the medium category, the nurses' performance was in the unfavorable category. Based on the analysis of the two variables, it was identified that there was no relationship between the quality of work life with the performance of implementing nurses with a p value of 0.817. The work context dimension is a component that has a relationship with the performance of nurses implementing with p value 0.008, the dimension of work life does not significantly correlate with nurse performance. The conclusion of the research is that there is no relationship between the quality of work life and the performance of the implementing nurses. There is a relationship between the dimensions of the work context and the performance of the nurses. There is no relationship between the dimensions of work life and nurse performance.   Keywords: quality of work life, performance, implementers nurse
