Opis:
The study aims at investigating the impact of ivy (Hedera helix L.) on the growth and on some wood anatomical characteristics of black alder trees. Ivy-hosting and non-hosting black alder have a similar wood anatomy in terms of qualitative properties. However, in ivy-hosting trees tangential and radial diameter of vessels are narrower (p <0.001), and inter-vessel pits are smaller (p <0.01), whereas vessel frequency is higher (p<0.05) than those of non-hosting ones. The average maximum ray height is greater (p<0.05), and ray number mm-1 is lower (p < 0.001) than those of non-hosting individuals. In addition, the last ten years’ average radial growth has decreased 39.5% compared to that of non-hosting black alder.

Opis:
Monitoring toxic metal concentrations in fish is very important for human health because fish, which are consumed by humans, can accumulate toxic metals from water up to hazardous levels. The aim of this study has been to monitor the levels of Cd, Pb, Cu, Cr and Ni in three deep-sea fish species as well as to make a risk assessment of their consumption. The samples were digested in a microwave oven and the determinations were made by atomic absorption spectrophotometry (AAS) and inductively coupled plasma-atomic emission spectrophotometry (ICP-AES). The mean lead concentrations in the Salmo salar and Sarda sarda species were found to be 955 and 948 μg kg-1, respectively, and these levels are three-fold higher than the risk threshold level of 300 μg kg-1. Cd concentrations in only six samples were slightly higher than the maximum allowable concentrations (MACs) of 100 μg kg-1. Mean Cr and Ni concentrations in Salmo salar were found to be 866 and 472 μg kg-1, respectively, and these results were higher than in Sarda sarda (mean 388 μg Cr kg-1 and 356 μg Ni kg-1) and Merlangius merlangus (mean 303 μg Cr kg-1 and 336 μg Ni kg-1). The measured Pb concentrations in all muscles of Salmo salar and Sarda sarda were found to be significantly higher than the MAC values, while Cd in all studied samples was around or lower than the MACs. However, there is no carcinogenic risk for humans, and the risk of developing cancer over an average human lifespan is between 2.5 and 13 in 1,000,000.

Opis:
This study deals with the wood of Marsdenia erecta R. Br., which is poorly known from a wood anatomical point of view. M. erecta, a woody-based perennial with numerous herbaceous sprawling stems, is distributed in the south and eastern parts of the Balkan Peninsula (incl. Crete)and Asia Minor to Afghanistan. The study aims at describing the wood anatomy of the species in detail based on IAWA list of microscopic features for hardwood identification, and at determining whether it has paedomorphic wood anatomical features. In M. erecta wood, the typical decreasing age-on-length graphic for vessel elements and exclusively upright and square ray cells provide strong arguments for paedomorphosis and secondary woodiness. However, to make a precise decision, this result based on wood anatomy should be checked with molecular phylogenetic data of the species investigated.

Opis:
Taxonomic identification on the basis of wood anatomy showed that 68.82% of wood charcoals from the Early Bronze Age Site at Yenibademli, on Gökçeada Island (Imbros) in the Northern Aegean region of Turkey belong to the genus Quercus, 15.88% to Pinus, 13.51% to Phillyrea, 0.63% to Arbutus, 0.35% to Ulmus, and 0.23% to the Rosaceae family. The results revealed that the dominant tree genus was oak (Quercus sp.), 67.2% of which was deciduous oak, and the remaining 1.62% was evergreen oak. Quercus and Pinus as the most common two genera in the spectrum of taxa may have a link with oak and pine stands on Gökçeada (Imbros) in the Early Bronze Age. Moreover, the evergreen Quercus (sec. Ilex) and the genus Phillyrea, which was third in the spectrum, suggest that maquis and open vegetation were also present in the Early Bronze Age on Gökçeada.

Opis:
Rinsing wastewater from dyeing and bleaching processes in a cotton dyeing facility has been separately characterized to evaluate the suitable treatment processes and reuse options. Alternative treatment processes were proposed based on molecular weight distribution (MWD), ultraviolet absorbance of 254 nm (UV254) and specific ultraviolet absorbance (SUVA). Rinsing wastewater samples were sequentially filtrated to determine the MWD of 5-day biochemical oxygen demand (BOD5), chemical oxygen demand (COD), dissolved organic carbon (DOC), total Keldahl nitrogen (TKN) and ammonium (NH4+). Bleaching rinsing wastewater had higher organic and nitrogen contents than dyeing rinsing wastewater and concentrations of pollutants decreased after each membrane filtration step. During the sequential filtration, BOD5/COD ratio in bleaching rinsing wastewater slightly decreased while it significantly increased in dyeing rinsing wastewater. SUVA values indicated that organic matters in the rinsing wastewaters have hydrophilic characteristics in all conditions. The evaluation of all experimental data indicates that combination of anaerobic treatment and NF membrane filtration could provide high quality water for reuse within the facility and discharge into receiving environments.

Opis:
Calf diarrhea continues to be the major problem of calves in the neonatal period. The effect of zeolites has been increasingly studied in ruminant health in recent years. In the present study, the efficacy of cristobalite, a zeolite, in neonatal calf diarrhea was studied first time. For this purpose, twenty-five neonatal calves with diarrheas were divided into two groups, and Group 1 (n=12) received conventional treatment and Group 2 (n=13) received cristobalite (Zoosorb 10 mg/kg) orally 3 times a day in addition to conventional treatment. Escherichia coli k99 and CS31a, bovine rotavirus and bovine coronavirus were isolated from fecal samples at the beginning of the treatment, on the third day and before discharge. It was determined that the recovery period in Group 2 was 0.95 (20.6%) days shorter than in Group 1 (p<0.05) while no viral agents were found on the fifth day in Group 2, viral shedding continued in 4 of 5 calves in Group 1. In conclusion, the study revealed that cristobalite speeds the recovery time and possibly decreases viral shedding in neonatal calf diarrhea, demonstrating a remarkable efficiency in the treatment.
