Solutions for increasing energy efficiency of industrial cooling plant (chiller) from S.C. Continental Sibiu

Scopul ciclului de racire este sa este sa indeparteze caldura acumulata dintr-un spatiu si a o evacueze in altul. Ciclul de racire se bazeaza pep e prncipiile fizice cunoscute in care un lichid expandeaza in gaz si astfel extrage caldura de pe suprafata. In lucrare sunt determinati parametrii energetici de performanta ai racitorului in functionare in accord cu EUROVENT

Impactul pe plan economic, tehnic, social si asupra mediului al nefinalizarii instalatiei de desulfurare de la S.E. Paroseni.

Through the approval of the Kyoto Protocol, the ONU Convention held in Europe and has taken to reduce the emissions of sulfur in large combustion installations through the development of projects for desulphurization flue gas in coal burning power plants to improve the reports relating to the impact on the environment. Desulphurization technology represents stations through which combustion products are treated in the process of burning coal of fossil fuels in order to reduce the concentration of SO2 (sulfur dioxide). The case study refers the Paroșeni power plant, one of the consumers of Jiul Valley hard coal, which, in these circumstances may remain a long run user of the local coal mines produced hard coal. So, the presence of hard coal in the energy mix of National Energy System could be preserved, taking into account the uncertain future of Mintia power plant, the second user of the mentioned above hard coal

Particular Anatomy of the Hyperopic Eye and Potential Clinical Implications

Background and Objectives: Hyperopia is a refractive error which affects cognitive and social development if uncorrected and raises the risk of primary angle-closure glaucoma (PACG). Materials and Methods: The study included only the right eye—40 hyperopic eyes in the study group (spherical equivalent (SE) under pharmacological cycloplegia over 0.50 D), 34 emmetropic eyes in the control group (SE between −0.50 D and +0.50 D). A complete ophthalmological evaluation was performed, including autorefractometry to measure SE, and additionally we performed Ocular Response Analyser: Corneal Hysteresis (CH), Corneal Resistance Factor (CRF); specular microscopy: Endothelial cell density (CD), Cell variability (CV), Hexagonality (Hex), Aladdin biometry: Anterior Chamber Depth (ACD), Axial Length (AL), Central Corneal Thickness (CCT). IBM SPSS 26 was used for statistical analysis. Results: The mean age of the entire cohort was 22.93 years (SD ± 12.069), 66.22% being female and 33.78% male. The hyperopic eyes had significantly lower AL, ACD, higher SE, CH, CRF. In the hyperopia group, there are significant, negative correlations between CH and AL (r −0.335), CRF and AL (r −0.334), SE–AL (r −0.593), ACD and CV (r −0.528), CV and CRF (r −0.438), CH (r −0.379), and positive correlations between CCT and CH (r 0.393) or CRF (r 0.435), CD and ACD (r 0.509) or CH (0.384). Age is significantly, negatively correlated with ACD (r −0.447), CH (r −0.544), CRF (r −0.539), CD (r −0.546) and positively with CV (r 0.470). Conclusions: Our study suggests a particular biomechanical behavior of the cornea in hyperopia, in relation with morphological and endothelial parameters. Moreover, the negative correlation between age and ACD suggests a shallower anterior chamber as patients age, increasing the risk for PACG
