Profiling the Senior Traveler: An Australia Perspective

Recently, the behavior of senior travelers has become an important area of interest because of its market size and potential for growth. This study describes a study profiling senior travelers according to their demographic and psychographic characteristics. Six market segments were used to highlight the differences that exist in terms of holiday attractions, travel motivations, and information sources used among senior travelers when planning and choosing a holiday. Seniors are shown not to be a uniform conservative market, which has implications for marketing and product development.

The tourism-leisure behavioural continuum

Tourism and leisure have historically been studied in isolation, but recent researchers attempt to understand the relationship between them. However, there have been few comparisons of how people behave in their environments. This paper provides a conceptual model of the relationship based oil a critical review of the current literature oil pleasure-oriented environments. The model indicates that despite potential differences in observable behavior, there is a commonality between the underlying influences that define how people behave during their leisure and tourism experiences. Therefore, the paper concludes that these should not be regarded as separate phenomenon. (C) 2002 Elsevier Science Ltd. All Lights reserved.

Tuna fishmeal as a source of DHA for n-3 PUFA enrichment of pork, chicken, and eggs

Enriching foods with long-chain n-3 PUFA (LC n-3 PUFA) is an important approach to increasing the dietary intake of these beneficial nutrients. Enrichment of meat and eggs can be achieved by adding flaxseed, fish oil, or fishmeal to pig or poultry feeds. However, utilization of these sources, particularly fishmeal, has been limited by concerns about adverse effects on sensory qualities, In this study, we evaluated the use of PorcOmega(TM) (POM), a stabilized tuna fishmeal formulation, as a source of DHA for enrichment of park and poultry products, Pigs, broilers, and laying hens were fed rations containing varying levels of POM for varying time periods, and its impact on the LC n-3 PUFA content and sensory qualities of cooked meat and eggs was examined. Pork and chicken products, including chops, sausages, and eggs, with substantially increased (up to sevenfold) levels of LC n-3 PUFA (predominantly DHA) were achieved by including up to 10% POM in rations. The increases were retained after cooking. Some sensory deficits were noted when using higher levels of POM (exceeding 15% in meat and 10% in eggs). However, at modest rates of feeding (5-10% POM), palatable meat and eggs were obtained with worthwhile levels of enrichment. The fishmeal feeding strategy used in this study offers a viable means of producing a range of alternative dietary sources of LC n-3 PUFA. Paper no.

Part 1. Growth, carcass and meat quality parameters of male goats: effects of genotype and liveweight at slaughter

Male kids (110) from six goat genotypes, i.e. Boer x Angora (BA), Boer x Feral (1317), Boer x Saanen (BS), Feral x Feral (FF), Saanen x Angora (SA) and Saanen x Feral (SF) and two slaughter weight groups, i.e. Capretto and Chevon (liveweight at slaughter 14-22 and 30-35 kg, respectively) were compared for growth, carcass and meat quality characteristics. Due to their better growth rate, kids from BS and SF genotypes reached the required liveweight for slaughter earlier than kids from other Genotypes used in the study. Chevon kids had a significantly (P < 0.05) lower average daily gain (119 g per day) compared to Capretto kids (171 g per day). SA, SF and FF kids deposited more internal fat in comparison to kids from other genotypes. The dressing percentage of kids ranged from 51 to 54%, with significant differences between genotypes. BS and SF kids had longer carcasses. while BF kids had larger eye muscle area compared to other genotypes. Goat carcasses had a thin subcutaneous fat cover (1.6-2.2 mm). Genotype had a significant (P < 0.05) influence on cooking loss, pigment concentration and muscle colour parameters (CIE L*, a* and b* values). As denoted by the higher V and fibre optic probe values and lower subjective muscle score, the longissimus muscle colour was lighter for BS kids than other genotypes. Cooked meat from the BF kids had lower shear force values and better sensory scores compared to other genotypes. A significant (P < 0.05) decrease in muscle tenderness was observed from Capretto to Chevon carcasses, whereas cooked meat from these two slaughter weight groups was equally accepted (P > 0.05) by the panellists.

Effect of storage time and conditions on the seed coat colour of Australian adzuki beans

Two varieties of adzuki beans (Vigna angularis), Bloodwood and Erimo, were stored at temperatures of 10, 20 or 30degreesC, and relative humidities (RH) 40 or 65%, and samples were analysed at 0, 1.5, 3 and 6 months. Storage at 30degreesC for > 1.5 months caused a significant decrease in the a(star) and b(star) colour values and darkening of the seed coat. Beans stored at 65% RH had lower L-star but higher a(star) and b(star) colour values than those stored at 40% RH. Bloodwood and Erimo samples showed similar trends in colour during storage. The best storage conditions for the preservation of the adzuki colour were 10degreesC and 65% RH. The Australian beans had lower L-star, a(star) and b(star) colour values than Japanese Erimo-shouzu beans and storage increased the difference.

Correlation between grain nutritional content and pasting properties of pre-gelatinized red rice flour

As with any variety of rice, red rice characteristics are subject to varietal differences, growing conditions, types of processing, and nutritional and rheological properties. This study determined the nutritional characteristics (centesimal composition and minerals) and paste viscosity properties of raw grains of four red rice genotypes (Tradicional MNAPB0405, MNACE0501 and MNACH0501) and the paste viscosity properties of pre-gelatinized flours obtained at different cooking times (20, 30 and 40 min). The main nutritional properties were correlated with the pasting properties of the pre-gelatinized flours. The samples showed differences in nutritional properties and paste viscosity. MNAPB0405 and MNACE0501 showed higher levels of fiber and fat and provided higher caloric energy than Tradicional and MNACH0501, which, in turn, showed higher levels of amylose. MNACH0501 showed higher peak viscosity (2402 cP), higher breakdown viscosity (696 cP) and a greater tendency to retrogradation (1510 cP), while Tradicional, MNAPB0405 and MNACE0501 had pasting profiles with peak viscosities varying between 855 and 1093 cP, breaking viscosity below 85 cP and retrogradation tendency between 376 and 1206 cP. The factors genotype and cooking time influenced the rheological behavior of pre-gelatinized flours, decreasing their pasting properties. The protein and amylose levels are correlated with the pasting properties and can be used as indicators of these properties in different genotypes of red rice, whether raw or processed into pre-gelatinized flours.

Será preciso lembrar que o 1º de Maio nasceu em Chicago-EUA?!

É vergonhoso e revoltante que seja o próprio Estado português a promover o despedimento em Portugal, qual país do 3º mundo. Muitas vezes não apenas junto dos trabalhadores do sector privado, mas também junto do próprio sector público. Agora, acreditam que existiram perfeitos ignorantes e idiotas em Portugal que chegaram nos tempos mais recentes a propor o fim deste feriado de cariz mundial?! § Abstract: It is shameful and disgusting that is the very Portuguese State to promote the dismissal in Portugal, which country in the 3rd world. Often not only among private sector employees, but also from the public sector itself. Now, believe that there were ignorant and stupid perfect in Portugal who arrived in recent times to propose the end of this world oriented holiday ?!

Constituição do Medo e Fim de 218.660 Empregos

Se uns têm medo da Constituição lusa actual, uma das mais humanistas do mundo, outros querem uma “Constituição do Medo”. Dizíamos no último artigo, um dia antes de Nª Srª da Assunção (ainda é feriado!), que o Art. 1º da Constituição, “República Portuguesa”, diz: “Portugal é uma República soberana, baseada na dignidade da pessoa humana e na vontade popular e empenhada na construção de uma sociedade livre, justa e solidária”. § If some are afraid of the current Portuguese Constitution, one of the humanists of the world, others want a 'Constitution of Fear. "We said in the last article, the day before Our Lady of the Assumption (it's still holiday!), That Article 1 of the Constitution, "Portugal", he says. "Portugal is a sovereign Republic, based on human dignity and popular will and committed to building a free society, justice and solidarity ".

Human case of gastric infection by a fourth larval stage of Pseudoterranova decipiens (Nematoda, Anisakidae)

Only three cases of human infection by anisakid nematodes have been reported in Chile since 1976. In the present case, an anisakid worm, identified as a fourth-stage Pseudoterranova decipiens larva, was removed with a gastroendoscopic biopsy clipper from the stomach of a 45 year-old man from southern Chile. The patient, who presented acute epigastric pain and a continuous sensation of having an empty stomach, reported having eaten smoked fish. The worm was fixed in 70% ethanol and cleaned in lactophenol for morphological study. The morphometric characteristics of the worm are described and drawn. Anisakid larvae in fish flesh can be killed by freezing or cooking.

Biodiesel production from waste frying oils over lime catalysts

Biodiesel production from semi-refined oils (SRO) and waste frying oils (WFO) was studied using commercial CaO as heterogeneous catalyst. The methanolysis tests were carried out in mild reaction conditions (62 A degrees C, atmospheric pressure). With such conditions, SRO (soybean and rapeseed) allowed to produce a biodiesel containing 97-98 % of methyl esters (FAME), whereas WFO only provided 86-87 % of FAME. The lower FAME yield for WFO oil is ascribable to the partial neutralization of the catalyst by free fatty acids. Also, soaps formation from the WFO oil reduced the weight yield of the oil phase (containing FAME) obtained and increased the MONG content of the glycerin phase. The catalysts stability tests showed high stability even when WFO oil was processed. Catalytic tests performed with blends of WFO/semi-refined oils showed blending as a good strategy to process low value raw oils with minor decay of the catalyst performance. Both WFO and semi-refined oils showed S-shape kinetics curves thus discarding significant differences of the reaction mechanisms.

Notice on a methodology for characterizing emissions of ultrafine particles/nanoparticles in microenvironments

Bearing in mind the potential adverse health effects of ultrafine particles, it is of paramount importance to perform effective monitoring of nanosized particles in several microenvironments, which may include ambient air, indoor air, and also occupational environments. In fact, effective and accurate monitoring is the first step to obtaining a set of data that could be used further on to perform subsequent evaluations such as risk assessment and epidemiologic studies, thus proposing good working practices such as containment measures in order to reduce occupational exposure. This paper presents a useful methodology for monitoring ultrafine particles/nanoparticles in several microenvironments, using online analyzers and also sampling systems that allow further characterization on collected nanoparticles. This methodology was validated in three case studies presented in the paper, which assess monitoring of nanosized particles in the outdoor atmosphere, during cooking operations, and in a welding workshop.

Determinação dos impactes ambientais e análise do ciclo de vida da produção de biodiesel

O consumo de energia tem vindo a crescer de uma forma contínua e directamente proporcional ao aumento da população e da industrialização. A maior parte da energia consumida no Mundo é, ainda, proveniente dos combustíveis fósseis. Contudo, a diminuição da reserva e a poluição atmosférica produzida pela sua utilização, estimulam e aumentam a necessidade de fontes alternativas de energia. O biodiesel tem atraído considerável atenção como combustível renovável, biodegradável e não tóxico, e pode contribuir para a resolução do problema energético, reduzindo significativamente a emissão dos gases causadores do aquecimento global. A primeira etapa deste trabalho consistiu na simulação de diferentes alternativas de processos de produção de biodiesel. O método usado para a produção do biodiesel foi a transesterificação entre os óleos vegetais e um álcool, na presença de um catalisador. Entre as matérias-primas figuram os óleos de palma e os óleos alimentares usados que foram objecto de estudo nesta dissertação. Na segunda etapa realizou-se uma análise do ciclo de vida para todas as alternativas em estudo seguida de uma análise económica para as alternativas que apresentassem menores impactos e que fossem mais promissoras do ponto de vista económico. Por fim, procedeu-se à comparação das diferentes alternativas sob o ponto de vista da análise do ciclo de vida e sob o ponto de vista da análise económica. Comprovou-se a viabilidade de todos os processos e o biodiesel obtido apresentou boas especificações. Do ponto de vista da análise do ciclo de vida a melhor alternativa foi o processo de catálise alcalina com pré-tratamento ácido para óleos alimentares usados. O processo que usa como matérias-primas os óleos virgens, o metanol e o hidróxido de sódio apresenta, no entanto, menores custos de investimento. Contudo, o processo de catálise alcalina com pré-tratamento ácido cuja matéria-prima principal são os óleos usados é muito mais rentável e apresenta menores impactes ambientais.
