Prebivalci lokalne skupnosti kot uporabniki severnoameriških visokošolskih knjižnic: poskus pridobivanja dodatnih finančnih sredstev
Authors: Dole Wanda V. , Hill J. B.
Published: August 2023

ABSTRACTIn 2007 the Ottenheimer Library at the University of Arkansas at Little Rock (UALR), decided to extend library privileges gratis to members of the community as a gesture of good will and a potential tool for fund-raising. Privileges extended include borrowing items from the circulating collection and use of reference materials (paper and electronic) and other non-circulating materials in the library building.Purpose: This paper reports the results of the five-year experiment to extend borrowing privileges to community users.Methodology/Approach: It describes the findings of a Web-based survey conducted to obtain information on demographics and community users’ perception of the value of library privileges (Dole and Hill, 2012) and the results of an appeals letter sent to solicit donations and to study the correlation between community users’ receiving library privileges and donating.Findings: Although these users had said that they value the services the Library extended to them and were more likely to donate money (Dole and Hill 2012), few did donate as a result of the appeals letter.Research Limitations: This paper reports on the responses of community users at one North American academic library and may or may not provide guidance for other libraries contemplating approaching community users for donations. The results of this study may or may not be generalizable to all academic libraries.Originality/Practical Implications: There has been little research that attempts to assess community users’ perception of the value of an academic library’s extending library privileges to them. Previous studies surveyed librarians about their perceptions of the pros and cons of extending privileges.
Everyday Information Needs and Information Seeking Habits in the Countryside: a Study of a Local Community
Authors: Vodeb Gorazd
Published: August 2023

ABSTRACTPurpose: The research attempts to provide an insight into the information world of the Slovenian countryside. It presents the first results of an exploratory study of information needs, information seeking habits and types of information sources.Methodology/approach: Brenda Dervin's Sense-Making Methodology was used as the theoretical basis for this research. 25 open structured interviews with inhabitants of a local community were conducted based on purposive sampling. Interview recordings were transcribed, summarised and analysed using the qualitative content analysis approach.Results: The analysis results in recognizing the types of gaps in the context of an individual, economic activities and in the context of a local community. Gap categories are described with regard to questions or problems and the ways of solving them. There are 20 categories describing gaps in the context of an individual, 17 categories which present economic activities – and 6 categories which pertain to a local community. Findings about information needs and the ways of seeking information stress the key role of information sources in farming and prevalence of interpersonal exchange of information and experts' opinion in the context of individual problem solving.Research limitation: The generalisation of results is not possible due to the sample size.Originality/practical implications: The findings contribute to understanding of information needs and ways of information seeking in the Slovenian countryside.

Expert Evaluation in the Flow of Information Science
Authors: Dekleva Smrekar Doris , Vilar Polona
Published: August 2023

AbstractInformation science is dealing with the study of all aspects of information, from its generation to its use, together with the planning processes and services for an efficient flow of information. This involves the transfer of knowledge, which is the crucial epistemological question of information science. In modern times, this is a very important issue because modern professional society is based on expert knowledge, which is founded on scientific research. The circle of scientific information is completed when all phases of information flow are connected. A completed information circle provides sustainable knowledge, scientific upgrading and development of science. In this way, the inputs and efforts in scientific research projects are confirmed. Scientific information today is still based on the publication of scientific papers. Published research results are the basis for assessing the quality of research work. Quality and responsiveness of scientific research are determined by using bibliometric methods and on the base of expert evaluation. Expert evaluation has a decisive influence on several levels of scientific research and publishing activities. It is important to maximize the objectivity - impartiality of expert evaluation. This article presents the baseline survey of the expert evaluation systems and the review of relevant work in this area.
Dr. Mirko Rupel: a Scientist who founded the National and University Library of Slovenia
Authors: Kodrič-Dačić Eva
Published: August 2023

AbstractProfessional tasks of Slovenian National and University Library were defined by a Slavicist and librarian dr. Mirko Rupel, who had a significant influence on the development of the library system after World War II. The article is focused on his professional work in the National and University Library. Under his supervision the Plečnik’s palace was finally reconstructed after the fire, which damaged it in 1944. He developed theoretical foundations of the basic functions of the national library, especially of the national bibliography, he organized central catalogue of foreign publications in Slovenian libraries and founded the department for library monitoring and development. He reformed the library organizational structure and implemented new library catalogues including the UDC catalogue. As to the library system, he strived for the developed library network and played an active role in the preparation and implementation of the new library legislation and formation of professional library training and education. He promoted libraries and coordinated acquisition among faculty libraries. He was a founder-member of Slovenian Library Society, its first president, and among founder-members of Association of Yugoslav Librarians and of Association of Yugoslav National Libraries. His professional work was widely recognised and in 1958 he took an active part at the UNESCO Conference on National Libraries in Vienna.
Bottlenecks in the Open-Access System: Voices from Around the Globe
Authors: Hladnik Miran
Published: August 2023

AbstractA level playing field is key for global participation in science and scholarship, particularly with regard to how scientific publications are financed and subsequently accessed. However, there are potential pitfalls of the so-called “Gold” open-access (OA) route, in which author-paid publication charges cover the costs of production and publication.Gold OA plans in which author charges are required may not solve the access problem, but rather may shift the access barrier from reader to writer. Under such plans, everyone may be free to read papers, but it may still be prohibitively expensive to publish them. In a scholarly community that is increasingly global, spread over more and more regions and countries of the world, these publication access barriers may be quite significant.In the present paper, a global suite of colleagues in academe joins this debate. The group of colleagues, a network of researchers active in scholarly publishing, spans four continents and multiple disciplines in the natural sciences, humanities, and social sciences, as well as diverse political and economic situations. We believe that this global sampling of researchers can provide the nuance and perspective necessary to grasp this complex problem. The group was assembled without an attempt to achieve global coverage through random sampling.This contribution differs from other approaches to the open-access problem in several fundamental ways. (A) It is scholar-driven, and thus can represent the ‘other side of the coin’ of scholarly communication. (B) It focuses on narrative report, where scholars were free to orient their responses as they saw fit, rather than being confined to binary or scalar choices. Finally, and perhaps most importantly, (C) it distinguishes among institutions and countries and situations, highlighting inequalities of access among wealthy and economically-challenged nations, and also within countries depending on the size and location of particular institutions.

Published: August 2023

AbstractThe paper presents the legal, organisational and technical perspectives regarding the implementation of the Slovenian national open access infrastructure for electronic theses and dissertations as well as for research publications. The infrastructure consists of four institutional repositories and a national portal that aggregates content from the university repositories and other Slovenian archives in order to provide a common search engine, recommendation of similar publications, and similar text detection. We have developed the software which is integrated with the universities' information and authentication systems and with the COBISS.SI. During the project the necessary legal background was defined and processes for mandatory submission of electronic theses and dissertations as well as of research publications were designed. The processes for data exchange between the institutional repositories and the national portal, and the processes for similar text detection and recommendation system were established. Bilingual web and mobile applications, a recommendation system and the interface suitable for persons with disabilities are provided to the users from around the world. The repositories are an effective promotion tool for universities and their researchers. It is expected that they will improve the recognition of Slovenian universities in the world. The complex national open access infrastructure with similar text detection support and integration with other systems will enable the storage of almost eighty percent of peer-reviewed scientific papers, annually published by Slovenian researchers. The majority of electronic theses and dissertations yearly produced at the Slovenian higher education institutions will also be accessible.
STANJE IN VIZIJA RAZVOJA BIBLIOBUSNIH SLUŽB REPUBLIKE HRVAŠKE
Authors: Pezer Iva , Vugrinec Ljiljana
Published: August 2023

(Prevedel / translated by: mag. Gorazd Vodeb)IzvlečekRepublika Hrvaška je razdeljena na 20 županij in Mesto Zagreb, ki ima status županije. Županija obsega več prostorsko povezanih občin in mest na svojem območju, v vsakem izvaja matično dejavnost županijska splošna knjižnica. Leta 2014 je na Hrvaškem delovalo 10 bibliobusnih služb na območju devetih županij in Mesta Zagreba, ki so skupaj imele 14 vozil. V 11 hrvaških županijah še vedno niso organizirane službe potujočih knjižnic, čeprav so v vsaki območja, ki niso pokrita s knjižnično storitvijo. To je bil razlog, da je Komisija za potujoče knjižnice Hrvaškega knjižničarskega društva leta 2013 izvedla Raziskavo o potrebah in načrtih razvoja potujočih knjižnic, v okviru katere je bilo opravljeno anketiranje v vseh županijskih matičnih knjižnicah. Predmet raziskave so bili kratkoročni in dolgoročni načrti razvoja županijskih mrež knjižnic s posebnim poudarkom na vlogi potujočih knjižnic. V članku so predstavljeni rezultati raziskave, poleg tega pa tudi podatki o aktualnem stanju bibliobusnih služb leta 2013, ki jih redno zbira Komisija za potujoče knjižnice. Skupaj dajejo celovito sliko stanja v potujočem knjižničarstvu Republike Hrvaške. Poudarjen je pomen bibliobusnih služb kot ključnega elementa v sistemu hrvaških splošnih knjižnic, ki prebivalstvu omogočajo kar najširšo dostopnost knjižničnih storitev.Abstract The Republic of Croatia is administratively subdivided into 20 counties and the City of Zagreb. Each county comprises many municipalities and towns. The library research and development service in the area of a county is provided by a county public library. In 2014 there were 10 mobile library services with 14 bookmobiles in nine counties and the City of Zagreb. 11 counties have not organised mobile library services yet despite the fact that many areas are still uncovered by the library services. This was the reason why in 2013 the Commission for mobile library services undertook a Research on the needs and plans of mobile library services development surveying all county public libraries. The research was focused on short term and long term development plans of a county library network with special emphasis to mobile library services. The results of the research are presented along with the data on the current state of mobile library services in 2013. The data are regularly collected by the Commission for mobile library services thus illustrating the current state of mobile library services in Croatia. The importance of mobile library services being a key element of the Croatian library system which offers access to a wide range of library services to the population is underlined.
PRVIH DESET LET UPORABE RAČUNALNIKOV V UNIVERZITETNI KNJIŽNICI MARIBOR
Authors: Sapač Irena
Published: August 2023

V članku je prikazan razvoj uporabe računalnikov v Univerzitetni knjižnici Maribor od začetkov leta 1982 do vključno leta 1992. Omenjene so tudi želje in priprave na uvedbo informacijske tehnologije pred letom 1982. Leta 1982 je bila sprejeta zgodovinska odločitev, da bo knjižnica sodelovala z Računalniškim centrom Univerze v Mariboru pri razvoju programske opreme in bo najprej podprla funkcijo izposoje. Leta 1985 pa je bila sprejeta druga zgodovinska odločitev, da bodo programi za bibliografijo in katalogizacijo zasnovani na formatu UNIMARC. Kmalu za tem je knjižnica informacijsko tehnologijo uvedla v sistem evidence raziskovalnega dela, sledile so vzajemna katalogizacija monografskih publikacij, serijskih publikacij, neknjižnega gradiva, domoznanska dokumentacija, evidenca nabave knjižničnega gradiva in medknjižnična izposoja. Že leta 1985 so uporabniki dobili prvo verzijo OPAC-a. Vzporedno z uvajanjem informacijske tehnologije v posamezne knjižnične funkcije je uvajala tudi informacijsko tehnologijo pri poizvedbah v domačih in tujih zbirkah podatkov, najprej v obliki on-line, kasneje v obliki CD-roma lokalno in CD-roma v mreži. Leta 1992 je bil uporabnikom dostopen tudi on-line vodnik po univerzitetnih knjižnicah delovne skupnosti knjižnic Alpe-Jadran.
IZBIRANJE LEPOSLOVJA V KNJIŽNIČNEM KATALOGU IN V KNJIŽNICI
Authors: Švab Katarina , Žumer Maja
Published: August 2023

Namen, zasnova: Namen prispevka je predstaviti zadovoljstvo uporabnikov, ki iščejo leposlovno gradivo s pomočjo knjižničnega kataloga, in ključne bibliografske elemente pri izboru med različnimi verzijami. Raziskava želi odgovoriti na vprašanje, ali obstoječi bibliografski zapisi zadostujejo za identifikacijo in izbiro leposlovja v knjižničnem katalogu v primerjavi s pregledovanjem fizičnih enot.Metodologija/pristop: Kvalitativna raziskava, ki je bila izvedena med 108 odraslimi uporabniki treh splošnih knjižnic, je uporabila osebni intervju in opazovanje kot metodo zbiranja podatkov. Za enega od treh naslovov (Boter (Mario Puzo), Varuh v rži (Jerome David Salinger) in Quo vadis? (Henryk Sienkiewicz)) je vsak udeleženec najprej uporabljal bibliografske zapise, nato pa je dobil v pregled vse fizične enote izbranega naslova.Analiza/rezultati: Prevladujoči način iskanja leposlovja v knjižnici je samostojno brskanje po policah in samostojno iskanje knjig s pomočjo knjižničarja. Avtor in kratka vsebina na naslovni strani sta v splošnem odločujoča kriterija za izposojo leposlovja, kadar brskajo po policah knjižnice, predvsem na t. i. priporočenih policah, medtem ko so v katalogu udeleženci kot ključne bibliografske elemente prepoznali jezik, leto izida, obseg in založbo. Zadovoljstvo z izbrano publikacijo na osnovi bibliografskega zapisa je 81-odstotno %, vendar bi jo 43 odstotkov uporabnikov zamenjalo z drugo, ko so videli vse verzije v fizični obliki. Najpogostejša razloga za zamenjavo sta bila ohranjenost knjige in lastnosti tiska v knjigi.Omejitve raziskave, uporabnost študije v praksi: Raziskava ima omejitve zaradi prostorske in časovne dimenzije, velikosti in sestave vzorca in metodološkega pristopa, vključenosti izbranih naslovov in njihovih verzij. Ugotavljalo se je predvsem uporabniški opravili identifikacija in izbira, v raziskavi pa ni bilo vključenega brskanja, iskanja in najdenja gradiva. Ta opravila bi bilo treba preveriti tudi za strokovno gradivo, raznovrstno gradivo na različnih nosilcih ter proučiti učinek in možnosti vključevanja obogatenih bibliografskih zapisov v knjižnični katalog.Izvirnost/uporabnost raziskave: Način raziskave je inovativen, ker zajema in proučuje dve uporabniški opravili in ugotavlja pomembnost bibliografskih elementov, zapisanih v katalogu, kot tudi kriterijev, ki vplivajo na izbor med publikacijami v fizični obliki. Predstavljeni prispevek proučuje problematiko (ne)uporabe knjižničnih katalogov in spodbuja knjižničarje in katalogizatorje k raziskovanju potreb uporabnikov, kadar ti iščejo leposlovje v knjižničnem katalogu. Glede na trend uporabe e-knjige pa tovrstni rezultati lahko pripomorejo k nadaljnjemu razvoju in večji pripravljenosti kataloga za tovrstno gradivo.

Published: August 2023

Namen: V članku je predstavljena raziskava, s katero je bil opravljen poskus opredelitve razlogov za pojav splošno veljavne predpostavke v slovenski knjižnični stroki, da »Slovenci ne berejo del domačih avtorjev«.Metodologija/pristop: Raziskava je potekala leta 2014 v Mestni knjižnici Ljubljana. Izbran je bil majhen vzorec petdesetih odraslih uporabnikov v petih izbranih enotah Mestne knjižnice Ljubljana. Podatki so bili zbrani s pomočjo delno strukturiranega intervjuja (vprašanja so bila pripravljena vnaprej, vendar v okviru intervjuja prilagojena pogovoru). Uporabljen je bil tudi vsakoletni seznam Najbolj brane knjige.Rezultati: Odgovori, zbrani v raziskavi, so bili po vsebini razvrščeni v naslednje skupine: (1) Problematika slovenskega romana; (2) Premalo poznani; (3) Tuje je boljše; (4) Izhaja iz šole; ter (5) Drugo.Izvirnost/uporabnost raziskave ter omejitve: Predstavljena raziskava je primarni poskus natančne obravnave vprašanja o branju sodobnih slovenskih romanov v osrednjeslovenski regiji. Zaradi premajhnega vzorca intervjuvanih oseb se rezultati sicer ne morejo posplošiti na celotno slovensko bralno populacijo, lahko pa predstavljajo osnovno referenčno točko za nadaljnje načrtovanje knjižničnih dejavnosti, ki spodbujajo branje slovenske literature v splošnih knjižnicah osrednjeslovenske regije.
MAISTROVA KNJIŽNICA: KAJ JE ZNANEGA O OSEBNIH KNJIŽNICAH ZNAMENITIH SLOVENCEV IN KAJ TE GOVORIJO O SVOJIH TVORCIH?
Authors: Kodrič-Dačić Eva
Published: August 2023

Poročilom o osebnih knjižnicah filozofov, znanstvenikov, literarnih ustvarjalcev in bibliofilov se da slediti od časov antične Grčije vse do današnjih dni. Osebne knjižnice so tudi na Slovenskem, podobno kot v drugih deželah Evrope, pogosto predstavljale temeljne fonde javnih knjižnic, pokrajinskih, visokošolskih in nacionalnih. Število osebnih knjižnic slovenskih izobražencev je začelo naraščati od srede devetnajstega stoletja. Osebna knjižnica generala Rudolfa Maistra, ki je nastala na prelomu stoletja, je bibliofilska zbirka, zbrana na osnovi selekcijskih kriterijev, ki so vezani na slovensko nacionalno identiteto. Zbiratelj ni skušal zbrati le slovenskega slovstva, temveč je težil k temu, da bi v celoti zajel vse publikacije, ki so bile izdane v slovenščini ali so jih izdali slovenski avtorji. Knjižnična zbirka odseva slovenske nacionalne tendence tega obdobja in predstavlja Maistra kot izrazitega domoljuba. Obsežne knjižnice so zbrali tudi številni Maistrovi sodobniki, vendar so le redke od njih so v celoti ohranjene, evidentirane in zaščitene.
Assessment of the interface shear strength between HDPE geomembrane and tropical soil by the direct shear test
Authors: Da Costa Junior Sérgio Luiz , Lodi Paulo César
Published: August 2023

Liners are important impermeable constituents of sanitary landfill to contain the transport of pollutants to the unsaturated zone. The system can be made of different kind, being the compacted soil and geosynthetics widely used. Thus, knowing the interface shear strength of those materials is important to avoid rupturing the system. The purpose of this paper is to compare the shear strength in the geomembrane-soil interfaces by the direct shear test. Assays were performed under the dry and saturated condition (water and leachate). The used soil is a colluvial, lateritic, tropical silty sand-clay, typical of the city of Campinas, in Brazil. In this work, high density polyethylene (HDPE) 2,00mm geomembrane, smooth and two texturized – with different roughness level - were used. It was found that the shear strength is directly influenced by the roughness of the geomembrane, showed higher friction angle in the textured geomembrane. The direct shear test, performed with soil contaminated by leachate showed smaller friction angle than uncontaminated soil.

Authors: Pinto Bruno Baiocchi , Salvador Ivania Itália Teixeira
Published: August 2023

Objetivo: Descrever a etiologia, epidemiologia, quadro clínico, diagnóstico e tratamento da atresia de vias biliares. Métodos: Realizou-se uma revisão bibliográfica abrangente, selecionando estudos relevantes publicados nos últimos dez anos. Foram analisados os dados principais para compor a revisão. Resultados: A atresia de vias biliares é uma condição rara em recém-nascidos, caracterizada pela obstrução das vias biliares intra e extra-hepáticas. Tem etiologia ainda incompreendida, estando envolvido fatores genéticos, imunológicos e ambientais estão envolvidos. Incidência variável entre populações, com uma prevalência estimada de 1 em cada 10.000 a 20.000 nascidos vivos, sendo a maior ocorrência nos países asiáticos O quadro clínico manifesta-se nas primeiras semanas de vida, com icterícia persistente, acolia e hepatomegalia. A progressão da doença leva à insuficiência hepática e cirrose. O diagnóstico requer exames clínicos, laboratoriais e de imagem, como ultrassonografia abdominal, cintilografia e colangiografia. A biópsia hepática avalia o dano hepático. O tratamento pode envolver cirurgia de Kasai, que cria uma anastomose biliodigestiva. Porém, a maioria dos pacientes necessita de transplante de fígado em algum momento da vida. Conclusão: A atresia de vias biliares exige diagnóstico precoce e intervenção cirúrgica adequada. Embora a cirurgia de Kasai possa melhorar a sobrevida, a progressão da doença e a necessidade de transplante de fígado destacam a importância de uma abordagem multidisciplinar em grandes centros de atenção a saúde.

Published: August 2023

The experiment was conducted to evaluate the interaction effect of age and body weight (BW) on ovarian responses in follicle stimulating hormone (pFSH) superovulated doe. Does (40) were divided into groups 1 (2–4 years old and 15–25 kg BW), 2 (2–4 years old and 26–35 kg BW), 3 (5–7 years old and 15–25 kg BW) and 4 (5–7 years old and 26–35 kg BW). Oestrus was synchronized by inserting a controlled internal drug release (CIDR) and a single injection of prostaglandin F2α. Does were administered 5 mg pFSH/kg BW, twice a day through 6 decreasing dosages. All does of Group 2 showed oestrus signs, while 70, 70 and 80% of does of group 1, 3 and 4 showed oestrus, respectively. Natural mating was carried out when does showed oestrus. Ovarian responses were evaluated on Day 7 after CIDR removal. Group 2 produced higher number of corpus luteum than other groups. Average number of embryo production was higher in group 2 than that in groups 1, 4 and 3. Transferable embryo production was higher in group 2 than in groups 4 and 1. Group 3 did not produce any transferable embryos. Numbers of anovulatory follicles per doe were similar in group 2 and 4, but higher than that in group 1 and 3 and did not show any differences. Does in group 2 gave higher number of embryos than other groups, indicating that donor age and BW interaction is an important consideration for superovulation in goats.

Published: August 2023

Feeding trial of 4 months was conducted on 24 crossbred cattle, which were subjected to treatment T0 (control), T1 (protected protein), T2 (protected fat) and T3 (protected protein and fat). Crossbred cows in second to fourth lactation with most probable production ability (MPPA) of average 2,300 litre milk production per lactation for each group were selected. All animals were fed with 2/3 DM through roughages (2/3 from dry and 1/3 from green) + 1/3 DM from concentrate mixture. In T0 and T2 groups, untreated groundnut cake was given in ration whereas, in T1 and T3 groups, groundnut cake was treated with formaldehyde (FA) @ 1.0 g FA /100g CP. Also bypass fat (99%) was supplemented in T2 and T3 groups @ 10 g/ liter milk production. The DMI was significantly higher in T3 followed by T1 , T0 and T2 . However, the DMI/100 kg body weight was nonsignificant among all treatment. The average digestible crude protein intake (DCPI) and total digestible nutrient intake (TDN) was significantly higher in T3 followed by T2, T1 and T0. However, DCPI and TDNI /100 kg body weight did not differ among all groups. The average milk production was 16.49% higher in T1, 13.93% higher in T2 and 20.99% in T3 over T0. Similar trend was observed in 4% FCM and ECM yield in all treatment groups. Reproductive performance of animal was significantly improved by feeding protected fat groups. By supplementation of protected fat, blood cholesterol and triglycerides level were significantly increased and BUN level decreased significantly by feeding protected protein.
Farmer’s opinion to minimize the constraints in scientific dairy farming practices of Nalanda
Authors: KUMAR SANJEEV , KUMAR ANAND , KUMAR SURYAMANI , KUMAR JITENDRA
Published: August 2023

The study was conducted to assess the alternative solution of constraints perceived by farmers in adoption of scientific dairy farming practice (SDFP). It is evident from the study, that poor conception rate and repeat breeding, preference to grow cereal crops rather than fodder crops, non-availability of vaccine and medicine in veterinary hospital and lack of knowledge in making value added dairy products were the major constraints in adopting SDFP by majority of farmers. Considering the prevailing constraints in the study area, appropriate strategy should be formulated by KVK with the assistance of line department or with other agencies for upgrading the knowledge of farmers as well as adoption of SDFP.

Published: August 2023

A study was carried out to detect the matrix metalloproteinases (MMP-2 and MMP-9) in tissues by gelatin zymography in various types of canine tumours. Fresh canine tissue samples (24) up to 0.5 cm were collected at the time of biopsy, surgery and necropsy. Tissue samples were homogenated, filtered and subjected to gelatin zymography. All the tumours samples were proteolytically active as they fully degraded the gelatin. Except with minor variation, in all tumours, the major bands were observed at 220, 135 and 92 kDa of MMP-9 and 72 kDa of MMP-2 band. Among all the groups, histiocytoma and malignancy tumours showed 3–4 times higher intensity bands than the other groups. This clearly showed that the expression of the active form of MMP-2 and intensity of other bands depends upon the degree and stage of tumour. The latent form of 72 kDa MMP-2 was thicker than that of 92 kDa MMP-9 as in mammary gland tumour and fibroadenoma. In histiocytoma, the expression of MMP-2 and -9 was almost similar. It was concluded that MMP-2 and MMP-9 could be used as a diagnostic tool/marker to ascertain the degree and stage of particular tumour, whether it has reached to the stage of metastasis or not. Further study on the difference between serum MMP and tissue MMP could be carried out to assess the degree of metastasis.

The primary objective of this experiment was to study the effect of replacement of concentrate mixture with molasses based multi-nutrient liquid supplements that contained either 2 (MMLS) or 4% mineral mixture (MMLS plus) on performance of buffalo heifers. Female Murrah buffalo heifers (18),12 to 14 months of age and weighing 290±2 kg were randomly distributed into 3 groups of 6 each in an experiment based on randomized block design. All animals were supplied with green forages (2 kg DM/d) and wheat straw ad lib. In addition, animals in group T1 (control) were fed a concentrate mixture to meet their nutrient requirements. However, 20% of the concentrates were replaced with MMLS and MMLS plus in groups T2 and T3, respectively. Digestibility of NDF and hemicelluloses was higher in T3 as compared to T2 and control. Digestibility of other nutrients, excretion of purine derivatives and growth performance were comparable among the groups. It was concluded that multi-nutrient liquid supplements can safely replace 20% concentrate mixture without any adverse effect on nutrient utilization and growth performance of buffalo heifers.

Climate variability refers to the way climate fluctuates yearly above or below a long-term average value. It is considered as one of the most serious long-term challenges faced by livestock rearers, in this context it is important to know about the adaptation strategies followed by the livestock rearers in combating the climate variability vagaries. The present study was conducted in purposively selected northern dry zone of Karnataka with 120 livestock rearers, the major findings of the study were: Majority of the respondents were following adaptation strategies like keeping, promoting and interested in local breeds (60.83%), about 42.50% of livestock rearers made changes in micro-climate in cattle shed/stall, and 47.50% of respondents were providing extra concentrate, minerals supplementation and feed additives to their livestock, etc. An ordered logit model is estimated to investigate the factors influencing adoption of various strategies to combat climate variability. Among the adaptation strategies, the proportional odds assumption was satisfied only for keeping, promoting and interest in local breeds; change in micro-climate in cattle shed /stall and shifting from large ruminants to small ruminants were found significant with the herd size; land holding and education level of the respondents and for other variables the ordinal regression was not performed. It was also found that livestock rearers followed the cost effective adaption strategies, and all the adaptation techniques were region-specific, requiring no external help and were inherently scientific.

Migratory pastoralism is common in Himalayas, practiced by Gaddi tribe of Himachal Pradesh. Understanding migratory system is relevant as >90% of state sheep and around 70 % goat populations is reared under this system. The study was undertaken to analyse characteristics, trends, constraints and impact assessment of improved managemental strategies enroute migration. After generation of base data, for studying the impact of improved practices and breeding management, these flocks were monitored and strategic managemental and breeding inputs were provided to these flocks throughout the year for next 3 years. Majority of the farmers belonged to medium flocks (50%), followed by small flocks (40.2%) while very few were with larger size flock (9.8%). On an average, these farmers derived more than 60% of their income of migratory goat and sheep husbandry. Farmer’s own flock was the primary source (68.4%) of breeding buck and they practice selection of male buck based on indigenous knowhow. Diseases, predators, environmental extreme, veterinary aid in high hills and marketing infrastructure were major constraints. The result of adopted flock over period of 4 year revealed that there was significant improvement in body weight, reproductive parameters and pre-weaning mortality. The study concluded that the migratory system is an integral part of hill farming and is sustainable since it is a very low input system which effectively counterbalances its constraints and makes it profitable. There is need to address concern of management during migration, develop effective extension messages and breeding plans.

This work aimed to determine the Sun Protection Factor (SPF) of a cream-gel based on norbixin through spectrophotometry. Samples of gel-cream A and B were prepared at a concentration of 0.2 μL/mL and the absorbances were measured in the UVB region and the SPF was calculated using the equation used in the Mansur method. The absorption spectrum of each cream-gel was obtained using the origin program. Gel-creams A and B showed absorption in the UVA and UVB region and also in the long UVA region, therefore, they presented photoprotective characteristics. Regarding the Sun Protection Factor - SPF, both the cream-gel A and the cream-gel B were considered photoprotective by ANVISA. Norbixin increased the Sun Protection Factor - SPF and this potentiation was proportional to its concentration. Therefore, the use of norbixin in photoprotective products proved to be effective, favoring an increase in the photoprotection of the formulations.

O material apresentado constitui parte dos resultados obtidos em uma pesquisa de pós-graduação sobre o Transtorno do Espectro Autista (TEA) na Residência em Pediatria. É sabido que uma das funções do pediatra é acompanhar e monitorar o desenvolvimento infantil e rastrear possíveis atrasos ou irregularidades. Objetivou-se investigar os conteúdos curriculares de um Programa de Residência Médica em Pediatria de uma universidade pública do Estado de São Paulo, identificando conteúdos relacionados ao desenvolvimento infantil e ao TEA. Trata-se de um estudo qualitativo exploratório-descritivo em que se lançou mão da pesquisa documental qualificada. A coleta de dados contou com a busca por radicais, possibilitando a identificação dos conteúdos relacionados à temática em foco, que passaram por uma análise interpretativa. Os achados mostraram que não há conteúdo específico ao TEA. O programa apresenta uma visão abrangente e integral do desenvolvimento infantil considerando seus diferentes aspectos (físico, cognitivo e psicossocial). Entretanto, esses conteúdos são apresentados de forma superficial e vaga. Conclui-se que, assim como de outros programas de especialização e cursos de graduação, o documento é generalista. Há baixa menção de aspectos relativos ao desenvolvimento infantil nas seções de atividades práticas, que são o foco dessa formação. Os achados mostram que os programas de residência médica em pediatria devem indicarem a inserção de conteúdos curriculares sobre o TEA, na garantia de promover uma formação atenta a ocorrência de um dos transtornos mais prevalentes na infância, sabendo orientar a conduta junto ao paciente e à família nas alternativas de tratamento.
