Carbon credit trading in Brazil: an overview of a new business sector

This article discusses the Carbon Credit Trading Market in Brazil and opportunities for technological development and innovation related. The international trade in carbon credits becomes a source of opportunities for developing countries because of the Clean Development Mechanism. Committed to reduce polluting levels from 2008 to 2012, and ahead, industrialized countries started to seek ecological solutions internally or compensatory actions such as buying carbon credits from low-emission countries. This strategy brought up a brand-new industrial sector that still requires productive structures and a solid international commercialization system. This is a qualitative study, based on documentary research, referring to the Brazilian territory. The data obtained point out a set of efforts such as researching and developing products and processes environment friendly. Other findings indicate opportunities to expand Green Economy Sector through supporting a set of newborn firms such as waste management and recycling, in addition to other actions that reinforce sustainable development opportunities to the country and, at the end, to the world.

Difficult macrocyclizations: New strategies for synthesizing highly strained cyclic tetrapeptides

Cyclic tetrapeptides are an intriguing class of natural products. To synthesize highly strained cyclic tetrapeptides; we developed a macrocyclization strategy that involves the inclusion of 2-hydroxy-6-nitrobenzyl (HnB) group at the N-terminus and in the middle of the sequence. The N-terminal auxiliary performs a ring closure/ring contraction role, and the backbone auxiliary promotes cis amide bonds to facilitate the otherwise difficult ring contraction. Following this route, the all-L cyclic tetrapeptide cyclo-[Tyr-Arg-Phe-Ala] was successfully prepared.

Nonprescription medicine purchases in New Zealand

This study aimed to explore purchases of non-prescription medicines in New Zealand. Researchers were stationed for 5 days in 12 pharmacies throughout New Zealand during June and July of 1999. A brief questionnaire was administered, for each medicine purchased, to all available purchasers aged 16 years and over. At least partial data were collected from 2,597 medicine purchases (approximately 71.2% of medicine sales). Respiratory products comprised 42% of sales. Pharmacists were involved in 19.9% of medicine sales. Pharmacy staff featured in 62.2% of 792 influences on first-time purchases. This study tested a viable method for data collection and yielded valuable pharmaceutical marketing data.

Immobilization of aluminum chloride on MCM-41 as a new catalyst system for liquid-phase isopropylation of naphthalene

A great deal of effort has been made at searching for alternative catalysts to replace conventional Lewis acid catalyst aluminum trichloride (AlCl3). In this paper, immobilization of AlCl3 on mesoporous MCM-41 silica with and without modification was carried out. The catalytic properties of the immobilized catalyst systems for liquid-phase isopropylation of naphthalene were studied and compared with those of H/MCM-41 and H/mordenite. The structures of the surface-immobilized aluminum chloride catalysts were studied and identified by using solid-state magic angle spinning nuclear magnetic resonance (MAS NMR), Fourier transform infrared (FTIR) spectroscopy, X-ray photoelectron spectroscopy (XPS), nitrogen adsorption, and X-ray diffraction (XRD) techniques. The catalytic activity of the immobilized catalysts was found to be similar to that of acidic mordenite zeolite. A significant enhancement in the selectivity of 2,6-diisopropylnaphthalene (2,6-DIPN) was observed over the immobilized aluminum chloride catalysts. Immobilization of aluminum chloride on mesoporous silica coupled with surface silylation is a promising way of developing alternative catalyst system for liquid-phase Friedel-Crafts alkylation reactions.

Morphological variation and host range of two Ganoderma species from Papua New Guinea

Two species of Ganoderma belonging to different subgenera which cause disease on oil palms in PNG are identified by basidiome morphology and the morphology of their basidiospores. The names G. boninense and G. tornatum have been applied. Significant pleiomorphy was observed in basidiome characters amongst the specimens examined. This variation in most instances did not correlate well with host or host status. Sporemorphology appeared uniform within a species and spore indices varied only slightly. G. tornatum was found to have a broad host range whereas G. boninense appears to be restricted to palms in Papua New Guinea.

Towards identifying the new structures formed on the γ-radiolysis of Ultem

Ultem irradiated up to 10.0 MGy has been analysed using C-13, H-1 and D-2 proton-carbon and proton-proton correlation NMR spectroscopy to shed light on the formation of new structures. Chemical shifts and correlation data were used to determine the structure or partial structures of several new components. The spectra indicated the presence of new groups and structures involving the isopropylidene group, the imide ring, and hydrogen-abstraction reactions. Possible pathways for formation of the new structures are proposed and the G-values for their formation have been estimated. (C) 2003 Elsevier Science Ltd. All rights reserved.

The 'parallel bridge' and its relevance to biotechnology new ventures

A firm's competitive strategy and innovation processes are strongly influenced by, and must be responsive to, its competitive environment. This is nowhere more strongly evident than in the high technology industries. In the present work, case studies of biotechnology new ventures are presented. These studies illustrate how an initial market entry strategy of parallel competition (through creative imitation) has enabled several biotechnology start-ups to reduce their mortality risk. We coin the term ''parallel bridge'' to describe this strategy. The parallel bridge provides early cash flows which support research and development and provide time for new ventures to develop core competencies, including a capacity to produce second and third horizon products that will sustain longer term competitiveness.
