In this paper, we use the variable precision method on approximate operators of the FRS model to expand measures to effectively evaluate attributes on noisy datasets. The main contributions of this paper include: Proposing new approximation operations to extend VPFRS to VPOFRS; proposing some measures based on VPOFRS to evaluate the consistency degree of the decision table and the dependence degree of the attribute.

Attribute reduction is one important part researched in rough set theory. A reduct from a decision table is a minimal subset of the conditional attributes which provide the same information for classification purposes as the entire set of available attributes.

In this paper, we build an incremental algorithm to find the approximate reduct according to the combined filter-wrapper approach. Experimental results on a number of sample datasets show that the proposed incremental algorithm is more efficient than some other incremental algorithms following the filter approach in terms of the number of reductive set attributes and classification accuracy.

Within the past two decades, Ethiopia has achieved one of the fastest reductions of open defecation worldwide. This change can be attributed to the implementation of a national sanitation strategy that focused on facilitating community demand for latrine adoption and use of basic self-constructed latrines but less on other preconditions of hygienic sanitation.

The precooling treatment did not show any enhancer affect in the quality indices of frozen berries. Compared to the other treatments, the use of 0.4% citric acid – 1% Ca lactate combination dip achieved better quality attributes, including reduction in drip loss and enhancement of firmness, retention of ascorbic acid and anthocyanin content in addition to improving in color attributes.

The purpose of this study was to evaluate the impact of salt reduction on bread physicochemical parameters and sensory analysis. The relationship between sensory attributes and preference was assessed using external preference mapping (PREFMAP). Moreover, sensory attributes relationship with physicochemical parameters was evaluated.

In this paper, a novel improvement in the catalytic Fenton reaction system named MHACF-NH2-MIL-101(Cr) was constructed based on H2 and Pd/NH2-MIL-101(Cr). The improved system would result in an accelerated reduction in FeIII, and provide a continuous and fast degradation efficiency of the 10 mg L-1 4-chlorophenol which was the model contaminant by using only trace level FeII. The activity of Pd/NH2-MIL-101(Cr) decreased from 100% to about 35% gradually during the six consecutive reaction cycles of 18 h. That could be attributed to the irreversible structural damage of NH2-MIL-101(Cr).

Coilia nasus (C. nasus) is an important anadromous fish species that resides in the Yangtze River of China, and has high ecological and economical value. However, wild resources have suffered from a serious reduction in population, attributed to the over-construction of water conservancy projects, overfishing, and environmental pollution.

Sunflower (Helianthus annuus L.) is an important edible oilseed crop in the country next to groundnut and soybean. One of the major factors for reduction in area of the crop is being attributed to the occurrence of fungal and viral diseases like sunflower necrosis disease (SND) and Sunflower leaf curl virus (SuLCV) resulting in yield loss in most of the sunflower growing regions of Southern and Northern India. In Karnataka, SuLCV has been reported to occur in almost all the popular sunflower hybrids grown during kharif, rabi and summer seasons with varied intensity.

An experiment was conducted to generate a broad genetic variability through induced mutation using physical and chemical mutagens. Three doses each of gamma rays (20, 40 and 60kR), ethyl methane sulphonate (0.2, 0.4 and 0.6%), nitrosoguanidine (0.005, 0.010, and 0.015%), maleic hydrazide (0.01, 0.02 and 0.03%) and their combinations were administered to the seed of two greengram varieties, Sujata and OBGG-52.

Two pot experiment was conducted at Instructional Farm of Krishi Vigyan Kendra, Raigarh (C.G.) during Kharif season, 2015 for identification of yield limiting nutrients through crop response in Vertisol and Inceptisol of Raigarh district of Chhattisgarh with rice (MTU-1010) as test crop. The experiments were laid out in Completely Randomized Design with 11 treatments and 3 replications. Yield attributing characters viz. effective tillers, filled grains panicle-1 and grain and straw yields of rice in both soil types were significantly influenced by nutrient omission treatments.

Cuscuta campestris is complete stem parasite and serious problem of lentil. It causes 87% yield loss. Manual removal of Cuscuta is labour intensive and cause high labour cost. Herbicides are the best option for the management of Cuscuta. In present study, impact of Pendimethalin, Quizalfop and Imazethapyr were observed on weed count of Cuscuta and yield attribute of Lentil. In both the year i.e. 2014-15 and 2015-16, Pendimethalin cause maximum reduction in weed count of Cuscuta, highest number of pod per plant and yield of lentil compared to Quizalfop ethyl and Imazethapyr.

A three year field experiment was conducted during the rainy season of 2014, 2015 and 2016 at farmer field in 66 locations (07 districts) of Bihar. The soil was sandy loam in texture and medium in organic carbon. The study was conducted to assess the important major nutrient for soybean crop through omission. The experiment comprised of 4 treatments, viz., T1 (100 % NPK), T2 (100 % PK, N omission), T3 (100 % NK, P omission), T4 (100 % NP, K omission).
