Heat and mass transfer during fry-drying of sewage sludge

Deep-frying, which consists of immersing a wet material in a large volume of hot oil, presents a process easily adaptable to dry rather than cook materials. A suitable material for drying is sewage sludge, which may be dried using recycled cooking oils (RCO) as frying oil. One advantage is that this prepares both materials for convenient disposal by incineration. This study examines fry-drying of municipal sewage sludge using recycled cooking oil. The transport processes occurring during fry-drying were monitored through sample weight, temperature, and image analysis. Due to the thicker and wetter samples than the common fried foods, high residual moisture is observed in the sludge when the boiling front has reached the geometric center of the sample, suggesting that the operation is heat transfer controlled only during the first half of the process followed by the addition of other mechanisms that allow complete drying of the sample. A series of mechanisms comprising four stages (i.e., initial heating accompanied by a surface boiling onset, film vapor regime, transitional nucleate boiling, and bound water removal) is proposed. In order to study the effect of the operating conditions on the fry-drying kinetics, different oil temperatures (from 120 to 180 degrees C), diameter (D = 15 to 25 mm), and initial moisture content of the sample (4.8 and 5.6 kg water(.)kg(-1) total dry solids) were investigated.

The histogenesis of lymphoid organs in Tilapia mossambica and antibody responses in adults and fry

The thymic anlagen appears in Tilapia mossambica at 2 days post hatching and becomes lymphoid at 5 days. Lymphoid cells were first seen in the pronephros at 14 days and in the spleen at approximately five weeks of age. Differentiation into red and white pulp regions was seen by 10 weeks of age. Light and electron microscopic studies of adult lymphoid organ revealed increases in size and lymphoid cell numbers. Adult thymus develops a clearer corticomedullary differentiation of thymic corpuscles in the medulla and in the splenic red and white pulp became more distinct. Melanomacrophage centres were seen in spleen and pronephros. Adult fish gave primary and secondary antibody responses following challenge with sheep red bloods cells (SRBC), Escherichia coli (E. coli) and human gamma globulin (HGG). Plaque forming cell and immunocytoadherence assays revealed that head kidney and spleen were major sites for antibody production and development of antigen reactive cells. Proliferative activity in these organs was revealed using autoradiography and scintillation counting. Increased levels of pyroninophilia were also seen following antigenic challenge. Pilot studies on adults revealed that they were capable of rejecting first and second set allografts and leucocytes from spleen and head kidney proliferated in mixed leucocyte cultures. Antibody responses to SRBC, E. coli and HGG develop at about 10-12 weeks of age. Fry given either a single injection of SRBC at 10 weeks or two injections of the same antigen at 10 weeks and 12 days later, failed to respond to a further challenge with SRBC 56 days after the first injection (A time when animals would normally respond positively to this antigen). Injection of E. coli at the same times resulted in a prolonged antibody response.

Study of nephrocalcinosis in rainbow trout (Oncorhynchus mykiss), from fry to brood stock

For survey incidence of nephrocalcinosis in rainbow trout fish, during winter 1385, samplings were performed in three fish farm with different water source: river, spring and recirculation system by using well water. In this survey 5 specimens from each 8 groups and in general 120 specimens of this fish were caught by random sampling, and also amounts of O2, CO2, pH and temperature of water were measured. Then blooding and renal tissue sampling performed that renal samples were fixed in 10% buffered formalin and blood samples after separating serum stored in -200C. Renal specimens transferred to pathology laboratory, pathological slides were prepared and stained by hematoxylin & Eosin method. From 120 specimens, 6 cases of fish represent nephrocalcinosis. Pathologic signs include: renal epithelial necrosis, dilated ureters, dense basophilic materials inside the dilated tubules and cast formation in some renal tubules. From 6 cases of nephrocalcinosis, 3 cases (7/5%) were related to recirculation system and 2 (5%) case were related to river water and 1 (2/5%) case was related to spring water. In survey amount of urea, creatinine and Uric acid between different weight groups, distinguished that difference between creatinine middling in different weight groups were significant and also in between healthy and afflicted fish, significant statistical difference were only in creatinine amount between healthy and afflicted fish in each farm. Amounts of O2, pH and temperature of water in three farms were in normal range and only rate of water CO2 in ponds of recirculatory system were very higher (25 mg/lit) than other farms. May be, this reason led to high number of nephrocalcinosis in recirculatory system, than other farms, nemley 7/5% of fish that caught from this farm .This subject is related to the role of CO2 in creating nephrocalcinosis which is descript in references.

Pilot scale production of sea bass (Dicentrarchus labrax) fry

Determination of rearing data enabled production of sea bass fry for three years in Station DEVA-SUD, CNEXO, France. The larval breeding process is described. The food consists of the ROlÎfer Brachionus plicatilis, then nauplii and 1 mm long metanauplii of the Brachiopod Artemia salina. Weaning on dry pellets oceurs when larvae are 35 days old when an optimum temperature curve is respected. Production of season 1977-78 was 380 000 two month old weaned fry.

Why fundamentalism?

Why Fundamentalism? was an exhibition proposal and critical writing project developed from concept phase through to detailed proposal. It included an edited video document that lay out its core ideas and presented the diverse voices of each collaborator. A number of key themes were engaged around the hot-button (and much misunderstood) concept of Fundamentalism. The proposal included an exhibition layout, developed test imagery, ideas and animations, proposed forms for future works and a process whereby design briefs would lead to subsequent commissions. Two major grant applications were submitted to the Australia Council and Arts Queensland, with the support of State Library of Queensland, the University of Adelaide and numerous others. The project remains at the developed proposal stage awaiting suitable funding----- Critically the show became an active vehicle for drawing and exploring a line of distinction between ideas of ‘what is fundamental’ and ‘fundamentalism’ as it rested in the popular imagination, as well as in political and philosophical debates. It teased out and engaged with a number of key questions that included The Problem of Ungroundedness, A Politics of Finitude, The Post-modern/Pluralist Problem, Silent Fundamentalisms (Voices of Reason and Neo-con Religions), Fundamentalism as a Media Construct, The Pre and Post Cold-war Other, The Pressing Need for Foundations in the West and Islam as Foundationalism (rather than fundamentalism).

Party 25

Party 25 involved the conception and public launch of a radically new form of political party during that year’s Australian general election. The entire project was also intentioned as a conceptual artwork. Party 25 avoided conventional party-political approaches and was neither a protest group nor an advocacy organisation, but rather a new form of political association that confronted what we understood as the debilitating limits and impotence of contemporary parliamentary democracies in transitioning our societies towards ecological sustainability.----- Party 25 was based on responding to one fundamental question which all of its policies served - “how does humanity get to the 25th century?” By basing itself on a dramatically long-term approach uncommon within conventional politics it raised the proposition that humanity does not have an assured future. Party25 therefore shaped its agendas around the idea that any future now lies in human hands and so how humanity treats the ecologies on which it depends innately determines the quality of the inseparable relationship between its being, and the being of the biophysical world.----- The project was conceived through a number of discussion papers, workshops and creative works and was launched publicly at the Judith Wright Centre Brisbane accompanied by a full length showing of evocative imagery, text and sound, a series of speeches and the launch of a succinct web presence. Through the website and this party launch a community of interested participants and creative practitioners was sought who then would form the basis of a nascent community of change.

Fundamental sounds

Fundamental Sounds was a live, intercultural and multidisciplinary concert that presented a new synthesis of music, performance & visual arts addressing the imperative of sustainability in a new and evocative form. The outcome was a ninety-minute concert, performed at a major concert hall venue, involving four live musicians, numerous performers & large-scale projections. The images and the concert were scripted in three key phases that spoke to three epochs of human evolution identified by ontological designer and futurist Tony Fry - ‘Pre-Settlement’, ‘Settlement’ and the era that he suggests that we have now entered – ‘Unsettlement’ (in mind body and spirit). The entire work was professionally recorded for presentation on DVD and audio CD.----- Fundamental Sounds achieved a new synthesis between quality performance forms and cogent critical ideas, engendering an increasingly reflective position for audiences around today’s “era of unsettlement” – an epoch Fry has recognized that we must now move to quickly displace through adopting fundamentally sustainable modes of being and becoming.----- The concert was well attended and evoked a range of strong, reflective reactions from its audiences who were also invited to join and participate within a subsequent ‘community of change’ initiated at that time.

Modeling the effects of strategic flexibility, organisational learning on e-business adoption and competitive advantage : an empirical investigation

The role of intangible firm capabilities as a source of competitive advantage has come into prominence in marketing strategy literature, due to the Resource Based View. This paper applies the Resource Based View and hypothesizes that strategic flexibility and organisation learning, conceptualised as capabilities, positively effect e-business adoption and competitive advantage. Partial Lease Squares analysis suggest that theoretical constructs function as hypothesised and explain a significant variation on e-business adoption and competitive advantage. Firms adopting e-business should develop capabilities such as strategic flexibility and organisation learning and that vendor firms may segment their potential clients based on these capabilities.
