Background: The aims of the present study were to assess whether the hard palate reveals any measurable sex-related differences, and to create a mathematical model which would differentiate between males and females using hard palate measurements alone. Materials and methods: The present study was conducted on 1,200 archived sinus computed tomography (CT) scans. Each cranial measurement was taken...
Deoxyguanosine kinase deficiency (dGK) is a frequent cause of the hepatocerebral form of mitochondrial depletion syndrome (MDS). A group of 28 infants with severe progressive liver failure of unknown cause was recruited for post mortem search for deoxyguanosine kinase (DGUOK) gene mutations. Four affected patients (14% of the studied group), two homozygotes, one compound heterozygote, and one heterozygote,...
This paper proposes a reduction of energy consumption in the implementation of semi-finished components of the planetary gear through the use of foundry technology. The authors compared the calculated amount of sliced material for individual pieces made in technology to bring the full semi-solid and prototype castings. Next presents the selection of materials, development of casting technology parts...
W opracowaniu przedstawiono model matematyczny pozwalający na określenie nakładów energetycznych, eksploatacyjnych i ekonomicznych ponoszonych na zbiór i zakiszanie całych roślin kukurydzy z uwzględnieniem strat powstających podczas poszczególnych operacji.
Przeprowadzono symulacje w celu określenia nakładów przy zbiorze kukurydzy sieczkarnią samojezdną i ze składowaniem sieczki: w pryzmie naziemnej, w pryzmie na płycie betonowej, w silosie przejazdowym oraz w worku foliowym. Koszty jednostkowe wyniosły odpowiednio: 59,60; 83,50; 87,60; 79,30 zł∙t-1 s.m.
Badania symulacyjne przeprowadzono z wykorzystaniem opracowanego modelu matematycznego w celu określenia jednostkowych nakładów zużycia paliwa, robocizny i kosztów w odniesieniu do jednostki powierzchni, masy materiału podczas zbioru i w odniesieniu do jednostki masy suchej substancji. Uwzględniono przy tym straty ilościowe, jak również pomijane dotychczas straty jakościowe wynikające z nierozdrobnienia...
A capillary electrophoresis (CE) method for the simultaneous determination of residues of six quinolones (enrofloxacin, ciprofloxacin, ofloxacin, lomefloxacin, norfloxacin, cinoxacin) in chicken, hen, and swine tissue samples were developed and validated. The sample preparation consisted of a solid phase extraction on C-18 cartridges prior to the analysis by CE with UV detection. The method was validated...
