This chapter reviews that the class resistance in Maine's paper industry has waned since the 1990s, including the movement culture which shaped and sustained it. It looks at the folk political economy and economic imagination that has resonance for Mainers and is considered a cultural artifact that can be joined in a critique of neoliberal capitalism. It also explores the widespread antipathy to key features of the neoliberal era. The chapter discusses the loss of local ownership and control of enterprises and the replacement of Chandlerian stability with the fierce and ugly rationalization imposed by financial investors. It refers to antipathy that is aimed at neoliberalism's assumption that only unfettered private markets provide good economic outcomes.

The pulp and paper sector has been a significant source of water pollution in China for many years. The Chinese government has made great efforts on water pollution control for the pulp and paper sector. While actively participating in various international treaties and conventions related to environmental management and pollution control in this sector, China has created a comprehensive environmental management framework, including several environmental policies, regulations and standards. This study reviews the current environmental framework for the management and control of water pollutants generated by the pulp and paper industry in China, with reference to relevant experiences. Apart from assessing the achievements that China has made, this study proposes some recommendations to further enhance water pollution control capacity and facilitate effective legal enforcement. Approaches such as improvements to environmental standards and permit systems, technical upgrading, cleaner production strategy, environmental monitoring improvements, integration of financing channels for environmental improvement, and enhancement of social responsibilities of enterprises are addressed.

And Control

The occurrence of filamentous bacteria was investigated in 15 French pulp and paper activated sludge wastewater treatment plant (WWTP). Large filamentous populations were present in most of the plants. Identification carried out with conventional methods based on morphological features and staining techniques showed that the four main filamentous bacteria encountered in these industrial WWTP and responsible for bulking belong to the genera Thiothrix sp., Type 021N, Haliscomenobacter hydrossis and Type 0092. During two years a specific survey was performed for three of these WWTP showing recurrent bulking phenomena. Data from WWTP performance, chemical data and filaments characterization were compared to correlate the presence of specific filaments with process operating conditions.

In the past decade, the Chinese paper industry, which is highly polluting and energy intensive, has shown overall increases in production, sales, income, and profit, although the growth rate has declined. Overall, China’s paper industry exhibits small-scale and scattered distribution, characterized by continuous overcapacity and outdated technical knowledge. This has inevitably resulted in a variety of serious environmental problems during its development. Owing to the environmental problems resulting from the development of the paper industry, various environmental regulatory policies and measures have been adopted in China, mainly command-and-control, market-based, and voluntary policies and measures. This study identifies and analyzes particular issues inherent to China’s environmental regulatory policies and measures regarding the paper industry and proposed policy suggestions for improving the environmental regulation of China’s paper industry.

And Control

Electric fields have been applied across oxides growing on a high temperature alloy and control of the oxidation of the material has been demonstrated. At present, three-fold increases in the oxidation rate have been measured in accelerating fields and the oxidation process has been completely stopped in a retarding field.The experiments have been conducted with an iron-base alloy, Pe 25Cr 5A1 0.1Y, although, in principle, any alloy capable of forming an adherent aluminum oxide layer during oxidation can be used. A specimen is polished and oxidized to produce a thin, uniform insulating layer on one surface. Three platinum electrodes are sputtered on the oxide surface and the specimen is reoxidized.

The majority of blood vessels in the superior cervical ganglion possess a continuous endothelium with tight junctions. These same features have been associated with the blood brain barrier of the central nervous system and peripheral nerves. These vessels may perform a barrier function between the capillary circulation and the superior cervical ganglion. The permeability of the blood vessels in the superior cervical ganglion of the rat was tested by intravenous injection of horseradish peroxidase (HRP). Three experimental groups of four animals each were given intravenous HRP (Sigma Type II) in a dosage of.08 to.15 mg/gm body weight in.5 ml of.85% saline. The animals were sacrificed at five, ten or 15 minutes following administration of the tracer. Superior cervical ganglia were quickly removed and fixed by immersion in 2.5% glutaraldehyde in Sorenson's.1M phosphate buffer, pH 7.4. Three control animals received,5ml of saline without HRP. These were sacrificed on the same time schedule. Tissues from experimental and control animals were reacted for peroxidase activity and then processed for routine transmission electron microscopy.

And Control

It is well known that the rat adrenal zona glomerulosa steroidogenic activity is controlled by the renin-angiotensin system. The ultrastructural changes in the rat zona glomerulosa cells induced by renovascular hypertension were described previously, but as far as we are aware no correlated biochemical and morphometric investigations were performed.Twenty adult male albino rats were divided into 2 experimental groups. One group was subjected to restriction of blood flow to the left kidney by the application of a silver clip about the left renal artery. The other group was sham-operated and served as a control. Renovascular hypertension developed in about 10 days: sistolic blood pressure averaged 165 ± 6. 4 mmHg, whereas it was about 110 ± 3. 8 mmHg in the control animals. The hypertensive and control rats were sacrificed 20 days after the operation. The blood was collected and plasma renin activity was determined by radioimmunological methods. The aldosterone concentration was radioimmunologically assayed both in the plasma and in the homogenate of the left capsular adrenal gland.
