s teel industries play a key role in the national economy and welfare of the society in many steel manufacturer countries. it is found that manufacturing and consuming of steel products would be a key indicator to measure and evaluate economic and industrial performance of a country. nowadays, countries with the large natural oil and gas resources (e.g. iran) attempt to select an alternative ec...

We study 3-valent maps Mn(p, q) consisting of a ring of n q-gons whose the inner and outer domains are filled by p-gons, for p, q ≥ 3. We describe a domain in the space of parameters p, q, and n, for which such a map may exist. With four infinite sequences of maps prisms Mp(p ≥ 3, 4), M4(4, q ≥ 4), M4(5, 5t+2 ≥ 7), M4(5, 5t+3 ≥ 8), we give 26 sporadic ones. The maps whose p-gons form two paths ...

The accuracy of water vapour observations from four different operational radiosonde types (Vaisala RS92, MODEM M2K2-DC and M10, and Meteolabor SnowWhite) flows simultaneously on the same ballon are intercompared and compared to GPS and Raman lidar measurements during the DEMEVAP 2011 experiment. The RS92 and Snow-White sondes show a slight moist bias at night-time compared to GPS, while the MO...

The presence of at least ten mouse LDH-A pseudogenes was demonstrated in the genomic blot analysis, and four different processed pseudogenes have thus far been isolated and characterized. In this report, the nucleotide sequences to two different mouse lactate dehydrogenase-A processed pseudogenes, M11 and M14, were determined and compared with the protein-coding sequences of the mouse and rat L...

This paper conducts an empirical study on output, costs and incomes in organic farming with a sample of Spanish firms. Financial accounting data reveals that organic and partly or transitional to organic farming do not get significantly different output than intensive farming. Farms in transition to organic farming bear significantly higher costs and obtain significantly lower income than inten...

Kekosongan persediaan material pada saat pelaksanaan proyek dapat mengakibatkan penyelesaian suatu pekerjaan menjadi terhambat sehingga akan mempengaruhi total waktu serta biaya proyek. Apabila terlalu banyak maka membutuhkan ruang penyimpanan dan terjadi penyusutan yang berdampak meningkatkan biaya. Untuk menghindari hal tersebut perlu dibuat perencanaan efektif efisien dengan mempergunakan me...
