Authors: Li Shuai , Zhang Jianmin , Chen Xiaoqing , Chen Jiangang , Zhou Gordon G. D. 
Published: February 2018

Abstract
Cavity length has been proven to have a significant effect on the air entrainment of an aerator in flood discharge engineering; however, the estimation of both the bottom and lateral cavity lengths downstream of a sudden fall-expansion aerator remain unclear. This research conducts a series of experiments involving various approach-flow conditions and geometric parameters of an aerator. An improved solution of the cavity length for the bottom and lateral cavities is established. The proposed equation was validated through the data of experiments and predecessor formulas, and exhibited a higher precision than other methods. Both the transverse turbulence and the axial dynamic pressure are found to be related to the formation of a lateral cavity. The present method involving the lateral cavity length was developed based on dimensional analysis and experimental test. The geometric morphology of a lateral cavity exhibits a parabolic shape, which is similar to that of the bottom cavity.

Published: February 2018

Abstract
Bioretention can be an effective measure for stormwater treatment. However, there is a lack of systematic analysis of the impact of bioretention design parameters on hydrologic performance. Herein, SWMM and RECARGA models were applied to generate the typical annual rainfall runoff and simulate the water balance of the bioretention system in an expressway service area. The purpose of the investigation was to identify key design parameters for the bioretention system and delineate the priorities in developing the design. Results showed that the average groundwater recharge ratios for bioretention basins with and without an underdrain were 58.29% and 92.27%, respectively, the average overflow ratios were 4.13% and 4.19%, the average evapotranspiration ratios were 4.48% and 4.47%, and the average outflow ratio for bioretention with an underdrain was 33.94%. The ratio of the bioretention area to drainage area, and the saturated infiltration rates of planting soil and native soil were the main factors influencing water balance, while the underdrain diameter and gravel layer depth exerted little effect. Based on the impact analysis, multivariate nonlinear regression models of runoff reduction rate for two types of bioretention basin were established, which both exhibited high determination coefficients and acceptable Nash–Sutcliffe coefficients.
Diurnal variations of the energy intensity and associated greenhouse gas emissions for activated sludge processes
Authors: Emami Nasir , Sobhani Reza , Rosso Diego 
Published: February 2018

Abstract
A model was developed for a water resources recovery facility (WRRF) activated sludge process (ASP) in Modified Ludzack-Ettinger (MLE) configuration. Amplification of air requirements and its associated energy consumptions were observed as a result of concurrent circadian variations in ASP influent flow and carbonaceous/nitrogenous constituent concentrations. The indirect carbon emissions associated with the ASP aeration were further amplified due to the simultaneous variations in carbon emissions intensity (kgCO2,eq(kWh)−1) and electricity consumption (kWh). The ratio of peak to minimum increased to 3.4 (for flow), 4.2 (for air flow and energy consumption), and 5.2 (for indirect CO2,eq emission), which is indicative of strong amplification. Similarly, the energy costs for ASP aeration were further increased due to the concurrency of peak energy consumptions and power demands with time of use peak electricity rates. A comparison between the results of the equilibrium model and observed data from the benchmark WRRF demonstrated under- and over-aeration attributed to the circadian variation in air requirements and limitations associated with the aeration system specification and design.

Application and limitation of molecular data and essential oil content in identification of Leutea elbursensis Mozaff in northern Iran
Authors: Emami-Tabatabaei Samane-Sadat , Larijani Kambiz , Mehregan Iraj 
Published: February 2018

Abstract
In this paper, the internal transcribed spacer (ITS) sequences, genetic structure and the chemical composition of essential oils of four populations belonging to Leutea elbursensis and Leutea petiolaris, two species endemic to northern Iran, are analyzed. Phylogenetic analysis based on the ITS data showed that all accessions of L. elbursensis formed a monophyletic clade, and L. elbursensis was a sister to the rest of Leutea species. Results of amplified fragment length polymorphism (AFLP) analysis performed on the total genome showed that all individuals presented in the study belonged to two different genetic clusters. The individuals belong to L. petiolaris had a different genetic structure and yielded no traceable amount of essential oils. The essential oil obtained from the ripe fruits of L. elbursensis yielded 0.5–0.6% of volatile essential oils. In total, 15-29 volatile natural components were identified on the basis of their mass spectra characteristics and retention indices, in which α-pinene (33.18-43.22%), β-pinene (32.4-40.9%) were the major constituents. Our results indicate that L. elbursensis is a distinct species, segregated from the other species based on morphology, ITS data and AFLP profile. In addition, despite the relatively uniform genetic structure of L. elbursensis, the chemical composition of essential oil could be highly affected by different factors.

Published: February 2018

Abstract
This paper is based on the main results of an analysis of spontaneous flora and vegetation on the small islet of Vrnik (0.281 km2), on which there are some abandoned limestone quarries, on the eastern Adriatic coast. The investigations were carried out from 2014 to 2016. Altogether, 251 vascular plant taxa (species and infraspecific units) were recorded on the islet. A total of 11 plant associations, one subassocation and two stands within 10 vegetation classes were identified. Due to high anthropogenic influences during the last centuries, quarrying in particular, the islet investigated showed a relatively low variety of vascular plant taxa. In addition, clear signs of fragmentation of the forest vegetation were observed.

Published: February 2018

Abstract
Chaenorhinum gerense is an eastern Mediterranean species with rare distribution and a large variety in plant and seed morphology. In this study, the accuracy of the taxonomic status of this species, which was initially reported by P.H. Davis as C. rubrifolium from south eastern Turkey, is discussed and the typical representatives of C. rubrifolium were collected for the first time for Turkey from Muğla province, southwestern Anatolia. C. gerense is closely related to the C. rubrifolium, from which it differs by having a small and cream corolla with red blotch, capsule as long as or smaller 1/2-calyx teeth and triangular or rectangular blunt crest on seed. Detailed descriptions and identification keys for these two taxa are provided.
Physiological and growth responses of sour cherry (Prunus cerasus L.) plants subjected to short-term salinity stress

Published: February 2018

Abstract
The gradual response of CAB-6P sour cherry (Prunus cerasus L.) plants to NaCl-induced salinity stress (60 mM NaCl) was investigated in a short-term hydroponic experiment, based on parameters relating to the growth, water relations, chlorophyll and mineral nutrition. The results showed that CAB-6P plants are very sensitive to salinity stress because their growth and leaf chlorophyll concentration were both affected negatively from the 3rd and 5th day, respectively, after incurring salinity stress. Since root growth was suppressed more severely than shoot growth, the shoot to root ratio was significantly increased under saline conditions. The concentrations of Na in leaves and stem of NaCl-treated plants were much lower than those measured in roots, suggesting Na exclusion mechanism from the shoot. The opposite trend was observed for Cl, indicating Cl inclusion mechanism to leaves. As regards the concentrations of Ca, Mg, P, K, Na, Fe, Zn and Mn, they were not changed in higher salinity conditions, apart from K, concentrations of which in leaves and roots were significantly increased and decreased, respectively (K translocation to leaves). Salinity further reduced K/Na ratio in root and stem as well as leaf water and osmotic potentials, whereas leaves of control and NaCl-treated plants presented similar turgor potential and K/Na ratio. These data add very important information to our knowledge about the physiological events occurring in sour cherry plants after even short-term exposure to salinity.

Abstract
The study investigated the effects of road transport infrastructure on agricultural sector development in Nigeria from 1985 to 2014, using secondary annual time series data on agricultural development (proxy by gross domestic product in the Agric sector) road transport infrastructure (proxy by length of paved road per square kilometer of area) export and capital, all obtained from the Central Bank of Nigeria (CBN) [3], and National Bureau of Statistics (NBS) [16], statistical bulletins. The data were analyzed using Granger Causality test and Ordinary Least Square estimation techniques. The study concluded that a positive and statistically significant relationship exists between road transport infrastructures (LRT) also evidence was found of a unidirectional causality from agricultural sector development to transport infrastructure. The study, therefore, recommends that adequate and timely maintenance of existing roads should be carried out as well as enacting appropriate regulations that ensure proper implementation and completion of new road construction contracts in the country in order to boost agricultural sector development, reduce wastage of farm produce and increase the possibility of economic diversification.
