COLLAGEN DETERMINATION IN DIFFERENT MEAT SAMPLES
No full textZadatak ovog rada je određivanje kolagena u 4 različite vrste mljevenog mesa. Kolagen se određivao u svinjetini, janjetini, govedini i mesu guske. Za analizu se koristila sumporna kiselina (H2SO4), DABA (dimetilbenzen aldehid), te kloramin (NH2Cl). Meso koje se koristilo za ovu analizu bilo je potvrđeno i provjereno od strane mentora, kao i svi ostali materijali koji su se koristili. Analiza se odrađivala na Sveučilištu u Krakowu, Poljoprivrednom fakultetu na odjelu Prehrambene tehnologije. Uzorci su pr ikupljani i analizirani u periodu od mjesec dana, iz razloga što se analiza provodila na 59 uzoraka mljevenog mesa. Svi analizirani uzorci prema Pravilniku o mesnim proizvodima (NN 131/2012) sadržavali odgovarajuću količinu kolagena.Task of this paper is collagen determination in 4 different types of minced meat. Collagen was determined in pork, lamb and in goose and beef. For this analysis sulfuric acid (H2SO4), DABA (p-dimethylaminobenzaldehyde) and chloramin (NH2Cl) were used. Meat used for this analysis was confirmed and verified by the mentor, like other materials that were used. This analysis was done at the University of Agriculture in Krakow, Faculty of Food Technology. This analysis is conducted in period of one month, because it was taken 59 samples of minced meat. Each sample analyzed according to the Ordinance on Meat Products (NN 131/2012) contains an appropriate amount of collagen

ASSESSMENT OF DIETARY HABITS AND NUTRITIONAL KNOWLEDGE OF PEOPLE WITH OSTEOPOROSIS
No full textOsteoporoza je kronična bolest povezana s visokim rizikom prijeloma kosti. Zajedno s primjenom lijekova koji usporavaju gubitak koštane mase ili potiču stvaranje nove kosti, dijetoterapija ima vrlo važnu ulogu u liječenju osteoporoze. Mediteranska prehrana uz poseban naglasak na dovoljnom unosu namirnica bogatih kalcijem i vitaminom D predstavlja zlatni standard prehrane za osobe s osteoporozom. Cilj ovog istraživanja bio je procijeniti znanje o prehrani i prehrambene navike bolesnika s osteoporozom. U istraživanju je sudjelovalo 100 ispitanika, 50 iz Opće bolnice „Dr. Josip Benčević“ u Slavonskom Brodu i 50 iz Kliničkog Bolničkog Centra Rijeka. Od ukupnog broja ispitanih bolesnika 95 je ženskog spola, a 5 ispitanika je muškog spola. Prosječna dob ispitanika iznosi 62 godine, a prosječni indeks tjelesne mase 26.4 kg/m2. Znanje bolesnika o prehrani u kontekstu liječenja osteoporoze može se ocijeniti kao nedostatno. Većina ispitanika ne zna da dnevne potrebe za kalcijem osoba oboljelih od osteoporoze iznose 1200 mg, a za vitaminom D 800 do 1000 IU. Jednako tako većina ispitanika ne zna koje namirnice su najznačajniji izvor kalcija u prehrani. Utvrđeno je da gotovo polovica bolesnika uzima dodatke prehrani koji sadrže kalcij. U ispitivanom uzorku samo polovica bolesnika uzima dodatke prehrani koji sadrže vitamin D što je nedostatno. I ovo istraživanje potvrđuje da su pojedini aspekti prehrane i ponašanja poput konzumacije gaziranih pića, kave i duhanskih proizvoda koji imaju nepovoljan učinak na kost još uvijek u prevelikoj mjeri zastupljeni u osoba s osteoporozom. Čak trećina ispitanika konzumira gazirana pića barem nekoliko puta tjedno, a kavu svakodnevno. Također, gotovo trećina ispitanika konzumira duhanske proizvode. Zadatak nutricionista je sudjelovati u osmišljavanju i provođenju ne samo individualne dijetoterapije osteoporoze već i edukativnih akcija u široj zajednici s ciljem osvještavanja mlađih dobnih skupina o važnosti uravnotežene prehrane, zadovoljavajućeg unosa kalcija, optimalnog statusa vitamina D i zdravih životnih navika kako bi se postigla i očuvala optimalna koštanu masa i spriječio razvoj osteoporoze, bolesti koja predstavlja tihu epidemiju, a koja je povezana s visokom smrtnošću i visokim troškovima liječenja.Osteoporosis is a chronic disease that is related with high risk of bone fractures. Together with the use of drugs that slow bone loss or encourage the formation of new bone, diet therapy has a very important role in the osteoporosis treatment. Mediterranean diet with special emphasis on the intake of food that is rich in calcium and vitamin D is the golden standard of nutrition for patients with osteoporosis. The main goal of this research was to assess the nutritional knowledge and eating habits of patients with osteoporosis. Overall one hundred patients participated in this research, 50 from General hospital „Dr. Josip Benčević“ in Slavonski Brod and 50 from Clincal Hospital Centar Rijeka. There were 95 female and 5 male participants. Average age of participants is 62 years, and avarage body mass index 26.4 kg/m2 . Nutritional knowlage of patients with osteoporosis can be reated as insufficient. Most participants do not know that daily needs for calcium of people with osteoporosis is 1200 mg, and for vitamin D 800 to 1000 I.U. Likewise most participants do not know which food is the most important source of calcium. It has been found that almost half of the patients take calcium-containing dietary supplements. In the examined sample, only half of the patients take dietary supplements that contain vitamin D, which is insufficient. This research confirms that certain aspects of diet and behavior such as consumption of carbonated beverages, coffee and tobacco products that have an adverse effect on bone are still overrepresented in patients with osteoporosis. As many as a third of respondents consume carbonated beverages at least several times a week, and coffee on a daily basis. Also, almost a third of respondents consume tobacco products. The task of nutritionists is to participate in designing and implementing not only individual diet therapy for osteoporosis but also educational actions in the wider community with the aim of raising awareness of younger age groups about the importance of a balanced diet, satisfactory calcium intake, optimal vitamin D status and healthy lifestyle to achieve and preserve the optimal bone mass and prevent the development of osteoporosis, a disease that represents a silent epidemic, and which is associated with high mortality and high treatment costs
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Dispelling the Myths Behind First-author Citation Counts
Full text linkWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
