A teoria da história como hermenêutica da historiografia: uma interpreta??o de Do Império à República, de Sérgio Buarque de Holanda
Assis, Arthur;
Revista Brasileira de História , 2010, DOI: 10.1590/S0102-01882010000100006
Abstract: this text features an interpretation of from the empire to the republic, the book by sérgio buarque de holanda that re-enacts brazil's late 19th century political history. based on concepts developed by the historical theorist j?rn rüsen, the article delves particularly into three aspects of the aforementioned book: the theoretical artefacts structuring the interpretation of the crisis of the brazilian monarchy; the narrative patterns deployed so as to make sense of that past experience; and the orientation context that functions as source of criteria of sense/meaning for both interpretation and representation. this analysis intends to illustrate that historical theory is not only a means to abstractly explore the complex questions connected to the production of historical knowledge, but also a tool for obtaining concrete images about the intellectual practice of professional historians.
Optimal Recovery of Holomorphic Functions from Inaccurate Information about Radial Integration  [PDF]
Arthur DeGraw
American Journal of Computational Mathematics (AJCM) , 2012, DOI: 10.4236/ajcm.2012.24035
Abstract: This paper addresses the optimal recovery of functions from Hilbert spaces of functions on the unit disc. The estimation, or recovery, is performed from inaccurate information given by integration along radial paths. For a holomorphic function expressed as a series, three distinct situations are considered: where the information error in L2 norm is bound by δ>0 or for a finite number of terms the error in l2N norm is bound by δ>0 or lastly the error in the jth coefficient is bound by δj>0. The results are applied to the Hardy-Sobolev and Bergman-Sobolev spaces.
Caracteriza??o tecnológica de extrusados de terceira gera??o à base de farinhas de mandioca e pupunha
Carvalho, Ana Vania;Vasconcelos, Marcus Arthur Mar?al de;Silva, Priscilla Andrade;Assis, Glaucy Takeda;Ascheri, José Luis Ramirez;
Ciência e Agrotecnologia , 2010, DOI: 10.1590/S1413-70542010000400028
Abstract: the objective of this work was to study the technological functional properties of third generation extruded products obtained from cassava (manihot esculenta crantz) and pupunha (bactris gasipaes kunth.) flour mixtures, in terms of apparent density, water absorption index (wai), water solubility index (wsi) and paste viscosity. the extruded products were formulated by adding 15%, 20% or 25% pupunha flour to cassava flour, and processing the mixtures in a pilot scale single screw extruder. the extrusion parameters were fixed by using five extrusion zones (at 30oc, 40oc, 60oc, 65oc, and 70oc); screw speed, 177 rpm; feed rate, 292g/min; laminar matrix with 1 mm. the formed third generation extruded presented relatively low or intermediate values of wai and wsi. after being fried, the extruded elements were expanded and thus their apparent density were reduced. development or application of technologies such as extrusion, which allow utilization of regional raw food materials such as cassava and pupunha, is a way of aggregating value to the natural resources, at the same time allowing development of new food products ready for consumption.
The Dog as a Risk Factor in Transmission of Visceral Leishmaniasis: A Review  [PDF]
Francisco Assis Lima Costa
Advances in Infectious Diseases (AID) , 2012, DOI: 10.4236/aid.2012.22006
Abstract: Visceral leishmaniasis (VL) is a serious public health problem in Brazil and worldwide. Despite the euthanasia of dogs serologically positive, such action has not solved the endemic in Brazil. A risk area for VL involves the presence of the vector, the occurrence of canines and the record of human cases. The factors that have favored the persistence and spread of VL in Brazil are related to the predatory action of man on the environment, to the migratory movements and rural exodus, and a close coexistence of man and animals. Thus considering the epidemiological chain of VL, one fact seems clear: we do not know yet the true extent of the participation of the dog in the infectious cycle of VL. The clinical disease is an important indicator of the extent of the problem in an endemic area. The immunological events are complex and involve resistance and susceptibility to canine visceral leishmaniasis (CVL). One aspect in CVL is that many symptomatic dogs underwent xenodiagnosis not infect the vector. In such cases the pattern recognition receptors CD11b+, TLR2+, and NO present higher values for dogs with results in immunohistochemistry of skin and xenodiagnosis negative (IMH-/XENO-) than dogs with immunohistochemistry in skin and xenodiagnosis positive (IMH+/XENO+), suggesting that innate immunity modulates the competence of the dog to infect the vector. The organic response in CVL varies from individual to individual and within the same individual, with a strong evidence of being organ-specific. Only 20% of asymptomatic dogs have parasites in the skin and 15% are able to recover from clinical signs and eliminate the parasites spontaneously. In this review, we analyze the epidemiology of visceral leishmaniasis and clinical, immunological and pathological conditions that can contribute to understanding the role of dogs in transmission of visceral leishmaniasis.

Yacubian, Elza Márcia T.;Valério, Rosa Maria F.;Jorge, Carmem Lisa;Fiore, Lia A.;Cukiert, Arthur;Assis, Luís Marques De;
Arquivos de Neuro-Psiquiatria , 1994, DOI: 10.1590/S0004-282X1994000200001
Abstract: we analysed 27 complex partial seizures arising from the temporal lobes recorded on videotape simultaneously with the eeg emphasizing the motor manifestations specially dystonic posturing, ictal paresis and head and eye forced deviation (version). the temporal lobe origin of the seizures was based on the agreement of many scalp-sphenoidal or zygomatic interictal and ictal eeg recordings, ct and mri findings, interictal and, in some patients, ictal spect studies. 8 patients had surgery. in 5 from 7 patients who had temporal lobectomy, mesial temporal sclerosis was the anatomopathological finding and in one patient who had selective amigdalohippocampectomy,.hemosiderosis and gliosis probably due to bleeding of a posterior cerebral artery giant aneurysm was found. all patients have been seizure free after surgery. while dystonic posturing and ictal paresis, present in 18 seizures(66.6%), were excellent as lateralizing seizure signs, since they were always contralateral to the ictal onset, contralateral and ipsilateral versive head and eye movements were observed.

Ciência Rural , 1998, DOI: 10.1590/S0103-84781998000300011
Abstract: the efficiency of enteral fluid therapy was checked in 14 equids (12 horses and two mules) presenting large colon impaction. the age of the animals ranged from 1.5 to 20 years old. all equids were fed chopped "capim elefante" (pennisetum purpureum schumach). the first colic signs were observed in the hospitalization day in six cases, one day before in five cases, three days before in one case, four days before in one case, and six days before in one case. one horse was sprayed with amitraz two days before the first colic signs. at hospitalization all animals showed dehydration, mild to moderate intermittent pain, dried feces, and impacted mass in large colon. eleven animals were medicated with analgesics. water was administered by nasogastric tube for all animals. the maximum volume administered at each time was 10 liters and the minimum interval between administrations was 30 minutes. the total volume administered for each animal ranged from 60 to 223 liters (mean, 119.14 liters). during treatment the animals were fed only with grain meal and mineral supplement. two physical exams were done every day and all equids showed poliuria, gradual abdominal volume reduction, feces softening, and regression of dehydration signs. duration of treatment was one to six days (mean, 2.57 days). at the end of fluid therapy, none animal showed abdominal pain or large intestino impaction. it may be concluded that enteral fluid therapy was efficient to treat large colon impaction in equids.

Revista de Saúde Pública , 1979, DOI: 10.1590/S0034-89101979000200007
Abstract: ascertainment of the antitetanic immune state in a group of 126 children, 5 to 7 years old, from the infant population of s. paulo city (brazil), disclosed 41% and 21% of 5 and 6-year-old individuals respectively, susceptible to tetanus. all the 7-year-old children showed protection against tetanus, revealing a circulating antitoxin content at levels superior to 0.01 iu/ml. by analysis of the results it became clear that susceptibility varies in inverse ratio to age. the mean content of tetanus antitoxin oscillated between 0.0289 and 0.1143 iu/ml of serum.
The rationale for pre-race aspirin to protect susceptible runners from sudden cardiac death during marathons: Deconstructing the Pheidippides conundrum  [PDF]
Arthur J. Siegel
World Journal of Cardiovascular Diseases (WJCD) , 2013, DOI: 10.4236/wjcd.2013.35A003
Abstract: Objectives: While endurance exercise such as training for marathons is cardioprotective, cardiac arrests and sudden death occur in previously healthy runners during races predominantly in middle-aged males due to atherosclerotic heart disease. Recent evidence related to this problem is reviewed herein including epidemiologic studies and findings related to acute cardiac risk in asymptomatic middle-aged male runners during races. Method: Literature review related to the above. Findings: The risks of cardiac arrest and sudden death were 1 in 57,002 and 1 in 171,005 respectively in runners with a mean age of 49.7 years among 1,710,052 participants in marathons in the United States since 1980. Atherosclerotic heart disease was the cause of death in over 90% of cases in two retrospective studies and a greater than two-fold increase in cardiac arrests was observed in middle-aged men in the latter half of a 10-year prospective registry beginning in the year 2000. Asymptomatic middle-aged male runners showed elevated biomarkers of inflammation such as interleukin-6, C-reactive protein together with procoagulant effects including in vivo platelet activation, indicating susceptibility to atherothrombosis. Conclusions: Antithrombotic prophylaxis is evidence-based by validated clinical paradigms to prevent cardiac arrest and sudden death in susceptibile marathon runners at high risk for atherothrombosis during races.

Motivating Generation Y and Virtual Teams  [PDF]
Arthur M. Baldonado
Open Journal of Business and Management (OJBM) , 2013, DOI: 10.4236/ojbm.2013.12006
Abstract: How can team members remain effective if members cannot engage in face-to-face interactions? Although the concept of global virtual teams has been a relatively new phenomenon, their use by organizations is a growing trend. The growth of globalization and the explosion of new technology have led to a new paradigm—a workplace that has no walls or boundaries. The purpose of the qualitative, descriptive study was to explore the motivational needs of Gen Y virtual team members and their impact in the workplace based on Herzberg’s two-factor theory of motivation. The participants consisted of Gen Y members at the Lakeland,Florida. The author used a researcher-developed, written survey as research methodology. The findings of the study revealed that Gen Y cohort placed great importance to both hygiene and motivator factors in their motivational needs. Advancement and personal life were both important to Gen Y participants. Managers must be flexible in their managerial approach to Gen Y workers.
A Hypothesis Concerning the Effect of Schedule on the Pattern of 5-Fluorouracil Toxicity  [PDF]
Arthur J. Weiss
Journal of Cancer Therapy (JCT) , 2015, DOI: 10.4236/jct.2015.63028

The significant effect that scheduling has upon the severity and types of drug toxicity has been known for many years. Evidence is available demonstrating that the schedule chosen will substantially effect the relative distribution of drug to various target organs. It has been shown that a likely cause for this with doxorubicin is that the efficiency of the various enzyme complexes responsible for disposing of the drug can be affected by scheduling. We believe a similar process can explain the marked effect that scheduling has on the pattern of 5-fluorouracil toxicity and present both clinical and computer data to illustrate this.
