Abstract

In this research different methods for measuring water quality indices were conducted to investigate the performance of the newly designed, constructed and operated 9-Nissan water treatment plant, Iraq. Data gathering and implementation took place throughout winter and summer. Water samples were taken periodically, according to the standard method, the re-search was carried out by collecting different random samples for eight months (Jun. 2015–Jan. 2016) and measuring (tur-bidity, total hardness, pH, total dissolved solids, suspended solids, Cl–, Mg2+, Fe2+,NO3–, NH3+) for each sample. Five dif-ferent approaches and methodologies of calculating the water index were applied. The results revealed that the Water Qual-ity Indices varied from 70.55 to 88.24, when applying Canadian Council of Ministers of the Environment Water Quality Index (CCMEWQI) and British Columbia water quality index (BCWQI) geometric weighted mean respectively. All the results, from the five approaches indicated good water quality, multiple regression analyses were conducted for turbidity, total hardness and suspended solids, they found that these parameters are strongly related to each other and to other pa-rameters.

Abstract

Several conjunctive use approaches can be distinguished. Drought cycling of groundwater (GW) usage and storage relies on more surface water (SW) during wetter years and delivers more water from GW during drought years. This method has the benefit of temporal changes in water availability. Additionally, it is usually desirable in areas with internal variability of SW where surface storage of wet-year surpluses is uneconomical, suffer excessive evaporative losses, or cause unacceptable environmental disruption. In previous studies, the purpose of operating the drought cycling was to reduce operating costs. In these studies, the objective function of the proposed model was to minimise the present value cost derived from the system design and operation to satisfy a predefined demand during a finite planning and operation horizon. However, it is important to consider other objectives in operating water resources systems, including minimising water shortages accurately. Hence, in this study, two scenarios were focused on: 1) mi-nimising water shortagages, 2) minimising operational costs. Pareto solutions are then presented with the objectives of minimising costs and water deficit. In this study, the weighting method has been used to extract Pareto options. The results show that reducing costs from 234 to 100 mln USD will increase water shortage from 9.3 to 11.3 mln m3.

Abstract

Background: Equine sarcoids are the most common neoplasms in horses. Bovine papilloma- virus type 1 (BPV-1) is the main viral type identified in equine sarcoids in Europe.

Objective: The aim of the present study was to genetically evaluate BPV types based on DNA analyses of the CDS of the L1 gene. The presence of BPV DNA was confirmed by Degenerate Oligonucleotide-Primed Polymerase Chain Reaction (DOP PCR) with FAP59/FAP64 consensus primers.

Results: The DNA was detected in 21/40 (52.5%) of clinically diagnosed sarcoids. More than half of 14 isolates (66.7%) shared 100% homology with BPV-1 Deltapapillomavirus 4 isolate 09 asi UK (Acc. No. MF384289) and 99% nucleotide identity with BPV-1 isolate EqSarc1 (Acc. No. JX678969). A comparison with BPV-1 isolate EqSarc1 revealed one silent mutation in C5827T which did not change the aminoacid codon. The remaining 6 isolates (28.6%) shared 100% nucleotide identity with the BPV-1 (Acc. No. X02346) “wild type” isolate, and 1 isolate (4.8%) demonstrated 99% nucleotide identity with BPV-2 (Acc. No. M20219).

Conclusions: Variants of BPV-1 isolate EqSarc1 (Acc. No. JX678969) constitute the most prevalent type of BPV-1 in Polish horses.
