Due to high perishability of tomato, it cannot be stored for long duration but by means of postharvest technologies somewhat can control their decay. Calcium as an essential plant nutrient actively participates in cell wall structure. The current experiment was conducted to find the effect of calcium on postharvest life of tomato fruit cv. "Dafnis". The experiment was co...
this experiment was carried out on lily cut flowers in greenhouse conditions and at the agricultural faculty of guilan university. the statistical factorial experiment was performed in a completely randomized design of three replications. the main factors studied were cultivars navona (asiatic) and fangio (la) along with four levels of calcium sulfate (0, 2.5, 5 and 10 mm) in combination with t...
soil ph is one of the important chemical characteristics of soil that plays major role in growing of tea plant and affects on absorbing of food elements by plant and their usability. in this study, the effect of different calcium source was investigated on some of quantifying parameters in tea plant, ph and ec in tea soil. tea is plant with shallow roots, this shrubs grows two forms wild and fa...
in this paper, we study the problem of minimizing the ratio of two quadratic functions subject to a quadratic constraint. first we introduce a parametric equivalent of the problem. then a bisection and a generalized newton-based method algorithms are presented to solve it. in order to solve the quadratically constrained quadratic minimization problem within both algorithms, a semidefinite optim...
i ntroduction: calcium hydroxide (ch) is one of the most common intracanal medications. corticosteroids (cs) are used in endodontics because of their anti-inflammatory activity. this study aimed to evaluate the antimicrobial effect of ch+betamethasone and ch+saline against enterococcus faecalis ( e. faecalis ) using agar diffusion test and measuring the microbial zone of inhibition (zoi). metho...
We present a set of Gupta potentials fitted against highest-level ab initio data for interactions of the alkaline earth metals: beryllium, magnesium, and calcium. Reference potential energy curves have been computed for both pure and mixed dimers with the coupled cluster method including corrections for basic set incompleteness and relativistic effects. To demonstrate their usability for the ef...
A common approach to increase reliability and efficiency of manufacturing systems is optimal scheduling. In this paper, we consider scheduling problems for a specific type of systems where batch processes are running in parallel. The goal is to schedule the interaction between the parallel processes, in the form of energy flows, to minimize a desired objective. We make use of a max-plus approac...

introduction: the aim of this in vitro study was to evaluate the effect of calcium hydroxide (ch) on push-out bond strength of white mineral trioxide aggregate (wmta) and calcium-enriched mixture (cem) cement in simulated furcation perforations. methods and materials: furcation perforations, measuring 1.3 mm in diameter and 2 mm in height, were created in 80 human mandibular first molars. the t...
Based on a putative 'Y shape' pharmacophore model of CCR5 inhibitors, a series of novel piperidine-4-carboxamide derivatives were designed and synthesized using a group-reverse strategy. Among synthesized target compounds, 16g (IC₅₀ = 25.73 nM) and 16i (IC₅₀ = 25.53 nM) showed equivalent inhibitory activity against CCR5 to that of the positive control maraviroc (IC₅₀ = 25.43 nM) in calcium mobi...
