Envelhecimento das aguardentes

1 - Colour, by itself, does not constitute a solid ground for judging of the age of a brandy because the more or less pronounced colour it acquires through aging can also be obtained by the addition of oack essence to newly distilled brandy. 2 - Urder the same conditions, colour intensity of a brandy wiU depend upon the nature of the wood and the condition of the storage. 3 - In accordance with the experimental results obtained by the present writers it rests no doubt that fermentation facility ferment resistence, produce and quality of the brendy all are factors depending upon the variety of the sugar cane. In addition, the authors presume that the variety of sugar cane has also influence upon the alteration of composition of the brandy submitted to aging. 4 - All aging phenomena of the brandy are accompanied by volume decreasing, what happens in a slow and continuous manner depending upon storage and environment conditions 5 - During brandy aging the alcoholic degree is greatly af- fected by evaporation, increasing or decreasing in accordance to the hygrometric state of the air and the teriperature in the place where the tuns are stored. 6 - The specific weight of the brandy is inversely proportio- nal to its alcoholic degree, but directly proportional to the extracts since the latter indicates the amount of dissolved residues. 7 - Brandy which shows high specific weight together with high alcoholic degree cannot be considered as aged. It may, however, be takens for brandy artificially coloved in order to conceal its actual age. 8 - The amount of extracts increases with aging, since it is the result of the solvent action of the brandy upon the soluble extractive substances of the wood. Notwithstanding that the extract, considered alone, has no value in determining the age of a brandy, since nothing easier is ohan to nake it change artificially. 9 -During aging the brandy get acidity in physiological as well as in physical way, but never by the action of microorganisms. 10 - The estturs produced during aging by the action of acids upon alcohols are the mean factors of the savour (bouquet) of a brandy and therefore every thing shall be done tor fhr estherification of a preserved brandy being not limited. 11 - Aeration increases esther formation, reduces the aging- time and turn better the taste qualities of the brandy. 12 - Due to the great proportion of high alcohols ordinarily found in the brandy, their analytical discrimination will be greatly important. 13 - The high alcohols are not responsable for the disastrous consequences of the alcoholism, but the high percentage of uthyl alcohol present in the brandy. 14 - The aldehydes appear always in high rate in the brazilian brandys in consequence of some intermediary products of the oxydation of the alcohols being left in the brandys during aging. 15 - The age has little or no influence on the quantity of phurphurol present in a brandy whose amount varies greatly the manner in which the wines to be distilled are treated. Wines centrifugalized or filtered before distillation always give rise to brandys poorer in phurphurol as compared with those distilled without these treatments. 16 - Though greatly variable, brandys of good qualities generally show a high residues coefficient, never under 200 mmg 17 - Lusson - Rocques oxydation coefficient cannot be indis- criminately applied to any brandy class, being, on the contrary, specifically destined to cognacs.

Aromatherapy with ylang ylang for anxiety and self-esteem: a pilot study

Objective: To verify if the use of ylang ylang essential oil by cutaneous application or inhalation alters the anxiety and self-esteem perception and physiological parameters as blood pressure and temperature. Method : A pilot study with 34 professionals from a nursing group randomized in three groups: one received the ylang ylang essential oil by cutaneous application, the second received through inhalation and the third (placebo) received the ylang ylang essence through cutaneous application. The assessment was done by an Anxiety Inventory (IDATE) and the Dela Coleta self-esteem scale, applied on baseline, after 30, 60 and 90 days and after 15 days post-intervention (follow up). Results : In the pre and post-intervention intergroup analysis, there was a significant difference in self-esteem for the three groups (p values: G1=0.014; G2=0.016; G3=0.038). There were no differences in the analysis between groups for anxiety or for physiological parameters. Conclusion : It was found significant alterations only to the intergroup perception of self-esteem for the three groups.


Participation of nurses in the execution of clinical research protocol about technological innovation

AbstractOBJECTIVETo report the nurse's experience of inclusion in interdisciplinary clinical study about technological innovation, involving people with spinal cord injury.METHODDescriptive experience report. The empirical support was based on notes about perspectives and practice of clinical research, with a multi-professional nursing, physical education, physiotherapy and engineering staff.RESULTThe qualification includes the elaboration of the document for the Ethics Committee, familiarization among the members of staff and with the studied topic, and also an immersion into English. The nurse's knowledge gave support to the uptake of participants and time adequacy for data collection, preparation and assistance of the participants during the intervention and after collection. Nursing theories and processes have contributed to reveal risky diagnoses and the plan of care. It was the nurse's role to monitor the risk of overlapping methodological strictness to the human aspect. The skills for the clinical research must be the object of learning, including students in multidisciplinary researches.CONCLUSIONTo qualify the nurse for clinical research and to potentialize its caregiver essence, some changes are needed in the educational system, professional behavior, attitude and educational assistance.

O impacto do PADCT na química e engenharia química

Among all activities related to the management of science and technology in Brazil, program monitoring and evaluation is certainly one of the less developed and most needed. There are no universal methodologies that can be applied. In essence programs can be evaluated by relating their achievements to pre-established goals. A second strategy is to compare programs similar in nature, utilizing as reference common indicators. Finally programs can be evaluated by their socio-economic impact comparing investments to outcomes. All strategies mentioned require appropriate program design monitoring and expert independent evaluation. In Brazil as in many other countries including developed ones this activity is complicated by the fact that programs vary widely in their scope and goals. In Brazil program designs often do not specify clearly their purposes and output indicators, many are not monitored properly which makes evaluation difficult. Consequently science and technology programs are difficult to be compared to each other, and even evaluated on the basis of pre-established goals. In PADCT monitoring and evaluation proved to be the most challenging activities. Two lessons however were learnt. One is that the process of monitoring and evaluation has to be continuously exposed to criticism to be perfected; and the second is that the evaluation process must not be exhausted shortly after investments since translation of scientific knowledge into industrial applications may prove to be a lengthy process. In this exercise we certainly do not pretend to evaluate the QEQ subprogram but to organize some of the information produced by different sources related to this subject, including the PADCT administration. We use somewhat each strategy described: compare the outputs of the QEQ to predetermined proposed goals (particularly in PADCT II), compare the QEQ to other PADCT subprograms, and specify some outputs in terms of technological and industrial applications. Finally, we utilize this opportunity to discuss science and technology M&E in general and the complexity of developing this area in Brazil.

A química medicinal na próxima década

Medicinal chemistry is multi, trans and inter disciplinary on its essence. It has a great deal of challenging Brazilian chemists in the next decade. The pharmacy school is essentially attached and has an important role in the development on the field that is still in domain of big pharmaceutical industries. This work shows the challenges to face and directions to jointly follow for a myriad of researchers throughout the country. The unnamed science has to work out through specific objectives in order to diminish the problems associated with human being health. A brief history is presented where the main goal is to devise chemistry, as a natural science, and many other interfaced disciplines.

Benjamin's conception of language and Adorno's aesthetic theory

According to the theory of language of the young Benjamin, the primary task of language isn't the communication of contents, but to express itself as a "spiritual essence" in which also men take part. That conception according to which language would be a medium to signification of something outside it leads to a necessary decrease of its original strength and is thus denominated by Benjamin bürgerlich. The names of human language are remainders of an archaic state, in which things weren't yet mute and had their own language. Benjamin suggests also that all the arts remind the original language of things, as they make objects "speak" in form of sounds, colors, shapes etc. That relationship between arts as reminders of the "language of things" and the possible reconciliation of mankind with itself and with nature has been developed by Theodor Adorno in several of his writings, specially in the Aesthetic Theory, where the artwork is ultimately conceived as a construct pervaded by "language" in the widest meaning - not in the "bourgeois" sense.
