Svježe mljeveno juneće meso tretirano kalijevim laktatom
(KL) i natrijevim laktatom (NaL) u količini od 4%
dodanima pojedinačno, odnosno svaki po 2% kada su
kombinirani, upakirano je u modificiranu ...atmosferu sačinjenu
od O2 i CO2 u omjeru 80%:20%, i skladišteno pri 2ºC
i 8ºC kroz 7 dana. Uzorci su analizirani prvi, četvrti, šesti
i sedmi dan. Rezultati ispitivanja pokazali su da je utjecaj
KL i NaL na broj aerobnih mezofilnih bakterija podjednak,
te su tretirani uzorci skladišteni pri 2ºC u svim kombinacijama
ostali unutar kontrolnih granica čitavo vrijeme skladištenja.
Pri skladištenju na 8ºC već četvrti dan skladištenja
netretirani (kontrolni) uzorci prelaze graničnu vrijednost za
log10 CFU od 6,00 do 6,17; čime prema pravilniku ulaze
u kategoriju neodgovarajućih za taj tip proizvoda. Organoleptičkom
analizom uzoraka u testu preferencije, uzorci
tretirani s KL ocijenjeni su bolje od uzoraka tretiranih s
NaL ili kombinacijom soli. Od pojedinačnih karakteristika
koje su ocjenjivane (boja, diskoloracija, prodajni izgled,
intenzitet stranih mirisa, prihvatljivost mirisa) uzorci tretirani
s NaL znatno su odstupali pri ocjeni mirisa; gdje su
pri obje temperature skladištenja uzorci ocijenjeni lošije
od netretiranih (kontrolnih) uzoraka.
Carotid artery stenting (CAS) is a widely used method in prevention of stroke for carotid artery stenosis as an alternative
to surgical treatment. Initial studies reveal higher morbidity and ...mortality rates for CAS than acceptable standards
for carotid endarterectomy (CEA). The aim of this study was to compare results in a series of CAS with concurrent
risk-matched group of CEA patients. The study included two groups of 50 patients with internal carotid artery stenosis.
We compared early outcome (30 days after procedure) in risk-matched groups of patients that underwent these procedures.
Post procedural complications were equally frequent in both groups. There was no significant difference in perioperative
complication rates (P=0.871). Comparison of these two methods shows that CAS and CEA are competitive
methods for treatment of carotid artery stenosis. Particularly in symptomatic patients with high risk for surgery CAS is
alternative treatment.
Multiple randomized trials over the last decade for both symptomatic and asymptomatic carotid stenosis have proven
the efficacy of carotid endarterectomy (CEA) in reducing the risk of stroke. The aim ...of this prospective non-randomizing
cohort study was to determine the incidence of carotid arteries restenosis after CEA as well as to ascertain the clinical
and etiological characteristics for the development of restenosis. Treatment data from 178 KBC Rijeka patients that had
undergone CEA in the period 1. 09. 2005–30. 8. 2009 has been processed. All patients are monitored trough our Neurosonology
laboratory algorythm – first Doppler ultrasound examination within the first week after CEA and the following
after 1, 3, 6 and 12 months. After this time once a years. The average monitoring time was 21 month (1–36 months). In
the stated period 27 restenosis was diagnosed (15.16%). Only four of them were symptomatic (14.81%). Patient survival
rate is 98% in the first 12 and 92% in the first 36 months. Carotid restenosis is usually asymptomatic. Non-invasive postoperative
carotid arteries color Doppler screening is essential in the early identification of patients with the risk for the
development of restenosis.
To meet the increasing requirements of sustainable production and to assure economic competitiveness, novel strategic approaches are necessary in designing production systems and to increase energy ...efficiency in the manufacturing industry. Individual areas within production facilities (e.g. production system, energy system, building hull) can be analyzed individually by using simulation-based methods. In order to access additional optimization potential, it is necessary to expand the boundaries of such simulations and to consider dynamic interactions between individual optimization fields. This work presents an approach for an interdisciplinary co-simulation, in which, for an overall integrated simulation, several simulation environments are coupled that periodically exchange data quasi-parallel at runtime. This allows not only to combine different model descriptions, but also multiple calculation algorithms, each specifically tailored to the individual needs of the respective field of engineering. A case study of a metal-cutting production facility presents an application example. The goal is to provide a decision-support tool for the early planning stages of production facilities that allows making qualified predictions about the effect and financial impact of different energy saving measures.
