面粉包装中粉尘的探讨

1前言面粉经过包装达到商品生产与流通的目的，而必须做到装量准确、封口牢固、包装环境卫生的要求，由于包装技术及设备上忽视粉尘预防措施，而导致粉尘，以致对设备本身与操作环境方面造成了一定程度的影响。2粉尘的起因在包装行业中，往往谈到被包物料时，将粉状物料与颗粒状物料相提并论。粉状物料与颗粒状物料一般是以颗粒度来区分的，物料约99％通过标准筛60目（0．25mm）的称之粉状物料。面粉即是粉状物料。面粉是具有干性、质轻、飞扬特性的物质。在面粉包装机上面粉的下料并非同时落入，而是形成粉流。这种粉流又不是自由落下，往…

散粮装／卸料斗的粉尘控制系统

1概述在散粮搬运、装卸作业中，往往会产生大量的粮食粉尘，造成很大的环境污染，同时也给工作人员带来很大的不便。在进行船舶、火车和汽车的散粮卸料作业过程中，由抓斗。其它散粮装卸设备或自卸汽车将散粮卸人散粮料斗时，随着粮食流动所带动的气流以及外界环境的影响如风力等因素，会产生粉尘外溢造成环境污染。国外散粮搬运、装卸设施比较先进的国家对散粮装卸过程中的粉尘控制问题进行了广泛和深人的研究工作，并且取得了显著的成效。在欧美等国家如：法国、荷兰、比利时等国，对粉尘控制要求非常严格。在粮食中转码头，散粮装卸中产…

Developments in Consumer Protection in India

This paper surveys the major developments in the field of consumer protection in India since 1984, when the statutory provisions for regulating unfair trade practices were incorporated for the first time.Among the developments described in the paper is the strengthening of provisions for consumer protection through amendments to the Act regulating restrictive and monopolistic trade practices (the MTRP Act). Public-sector undertakings and co-operative societies have been brought within the purview of the Act, and consumers have obtained the right to participate in inquiry proceedings before the MRTP Commission.Consumers and their associations have been given the right to seek redress of grievances arising out of the violation of certain pieces of legislation, including the Drugs and Cosmetics Act. The Consumer Protection Act, 1986, was enacted in order to provide speedy and inexpensive redress of consumers' grievances. Redress can now be sought before any consumer court also for negligence or deficiency in medical services.The Bureau of Indian Standards Act, 1986, has strengthened the measures for the standardisation and quality control of manufactured goods.A Consumer Welfare Fund has been set up to provide financial assistance to voluntary consumer organisations and for the general development of consumer movement in the country. A spurt in voluntary consumer organisations in different parts of the country can also be observed.Other developments include the establishment of a separate Department of Consumer Affairs in the Union Government and the setting up of a Consumer Product Testing Laboratory.

Healthy Investments in Investing in Health

This article discusses socially responsible investing (SRI) and tobacco. SRI allows investors, both institutional and individual, to express their concerns and make their social and ethical stands known to the companies they invest in and patronize. The tobacco industry is active in every country on the globe and generates huge profits, while tobacco use is responsible for 4 million deaths every year.The authors explore past and current views on investment in tobacco, partly based on a survey conducted by the Tobacco Free Initiative of the World Health Organization (WHO). There is clearly a trend toward divestment from tobacco for both ethical and financial reasons. Tobacco-free investments can be both ethically sound and financially profitable.

Conflict in Supplier–Retailer Relationships in the Brewery Industry in Cameroon

The authors develop a theoretical framework to explain conflict in supplier–retailer relationships. In addition to traditional influence strategy variables, the framework links conflict to retailer dependence and supplier formalization. The framework is empirically tested in the Cameroonian brewery industry. The findings support the view that channel conflict is inversely related to retailer dependence and supplier formalization. Contrary to expectations, the use of noncoercive influence strategies (information exchange and recommendations) has no significant effect on conflict, while, as expected, the use of coercive influence strategies (threats and promises) increases conflict.
