Mapping gender and marital roles on customer delight by value perception for mobile technology in India

The Indian telephony industry is a diverse platform for product and service in customer value perception. The present study organizes and synthesizes the varied research streams for developing a customer value delight (CVD) framework for marketing decisions like segmentation and targeting. The conceptual framework is developed by using ten-value predictor variables and customer delight through divergent viewpoints identified from previous studies. The significance of the segregation proposition is tested through discriminant analysis in three different dimension runs i.e. delight, gender, and marital category. The scholarship behind the study provides insight into an imperative issue of segregating customer delight by perceived value predictors in categories. The perceptual mapping and vector magnitude analysis of value predictors were performed to club customers in two categories of Mid-Town (low/moderate delight) and Extremes (high delight). The analysis rigorously supports the discriminating power of perceived price, perceived benefit, and self-congruity. The salience of study unlocks psychographic and demographic perceptual maps of customer delight with its perceived value predictors for strategic and tactful planning in the mobile industry.

Kinetic,thermodynamic parameters and in vitro digestion of tannase from Aspergillus tamarii URM 7115

Tannase is an enzyme used in various industries and produced by a large number of microorganisms. The aim of this study was to evaluate tannase production to determine the biochemical, kinetic, and thermodynamic properties and to simulate tannase in vitro digestion. The tannase-producing fungal strain was isolated from “jamun” leaves and identified as Aspergillus tamarii. Temperature at 26°C for 67?h was the best combination for maximum tannase activity (6.35-fold; initial activity in Plackett–Burman design—15.53?U/mL and average final activity in Doehlert design—98.68?U/mL). The crude extract of tannase was optimally active at 40°C, pH 5.5 and 6.5. Moreover, tannase was stimulated by Na⁺, Ca²⁺, Mg²⁺, and Mn²⁺. The half-life at 40°C lasted 247.55?min. The free energy of Gibbs, enthalpy, and entropy, at 40°C, was 81.47, 16.85, and ?0.21?kJ/mol?·?K, respectively. After total digestion, 123.95% of the original activity was retained. Results suggested that tannase from A. tamarii URM 7115 is an enzyme of interest for industrial applications, such as gallic acid production, additive for feed industry, and for beverage manufacturing, due to its catalytic and thermodynamic properties.

骆马湖生态建设

骆马湖为浅水湖泊,具有典型的过水性特征,已经处于中富营养化阶段。通过对骆马湖富营养化发生机制的研究,发现入湖河道携入大量营养物质入湖和水生植物的破坏是骆马湖富营养化进程加快的主要原因。为了保护骆马湖水质,提出对骆马湖生态建设的意见:建立自然保护区,建设入湖口人工湿地,建设骆马湖生态湖滨,通过生态渔业和生态旅游实现骆马湖的可持续开发。

上海市水环境生态安全评价

从“状态—压力—响应”指标框架体系出发,针对上海市水环境生态系统的现状特点,从时间变化和空间对比分析角度分别建立了上海市水环境生态安全评价指标体系;利用标准化和变异系数法确定各指标的标准化值和权重,采用综合指数评价法得到安全评价的综合指数值。在此基础上采用等级划分法,建立起综合指数值与生态安全评判的等级关系。各指标层的变化趋势揭示了上海市水环境生态安全的现状和发展趋势,即中心城区的水环境生态安全等级普遍低于郊区;在年际变化上,状态指标层评价值呈下降趋势,需要持续保护水环境生态系统;而压力和响应指标层评价值不断上升,保证了总体的良性发展趋势。
