Stanje, mogućnosti i perspektive oplemenjivačkih progarma krastavaca (Cucumis Sativus L.) u Srbiji
Climatic conditions provide growing cucumbers Serbia as an open field and in greenhouses. Growing in greenhouses makes it possible to fruits of cucumber from domestic production on the market for almost the entire year. This capability dramatically increases the economic efficiency and thereby directly encouraged producers to cultivation of this plant species.
Markets directly affected the characteristics of the fruit cucumbers that will be desired. This trend breeding companies must follow in order to offer farmers varieties that corresponds to preferences market. Also, farmers want high yield. The yield of cucumber is directly dependent on the expression of sex type plants.Klimatski uslovi Srbije omogućavaju gajenje krastavaca kako na otvorenom polju, tako i u zaštićenom prostoru. Gajenje u zaštićenom prostoru omogućava da se plodovi krastavca iz domaće proizvodnje mogu naći na tržištu skoro tokom celo godine. Ova mogućnost drastično povećava njegovu ekonomsku profitabilnost a time direktno podstiče prozvođače na gajenje ove biljne vrste.
Tržišta direktno utiču na karakteristike krastavaca koje će bit cenjene. Ovaj trend oplemenjivačke kompanije morju pratiti kako bi proizvođačima ponudile sortiment koji odgovara željama kupaca. Takođe, proizvođači zahtevaju i visok prinos. Prinos kod krastavca direktno zavisi od tipa polne ekspresije biljaka
Karakteristike proizvodnje semena povrća u Srbiji
Seed production in the Republic of Serbia is a very important sector of agriculture.
This production is taking place in public and private sector. Although seed production in
Serbia can meet domestic demands, a certain amount of seed is being imported.
Unfortunately, some vegetable producers (except for organic, dynamic or bio
production) use a certain amount of vegetable seeds from their own mercantile
production. Crops produced from such seed generate low yields due to poor seed quality
(varietal impurity, low germination) and health.
The study covered four years (2007-2010) and the surfaces under the vegetable
crops aimed for seed production: 2007 (956 ha of seed produced in Serbia of which 64.9
ha produced by the Institute for Vegetable crops); 2008 (1152 in Serbia, 137 ha the
Institute); 2009 (1219 ha in Serbia, 242.1 ha the Institute); 2010 (976 ha in Serbia, 198.7
the Institute).Proizvodnja semena je veoma bitna sa aspekta održivosti poljoprivrede
jedne zemlje. U današnjoj eri sekvencioniranja, mapiranja i nadasve zaštite istraženih
sekvenci, ovakve tendencije predstavljaju mogućnost za objektivnu zavisnost od
istraživača (vlasnika) koji su odredili pojedine sekvence odgovorne za nasleđivanje
pojedinih - traženih osobina novoselekcionisanih sorata. Posebno poglavlje ove
problematike predstavljaju i GMO organizmi i njihova prezentacija širokoj proizvodnoj
praksi kroz novonastale selekcije. U Republici Srbiji nije dozvoljena upotreba GMO
selekcija ali smo svesni da se vrši pritisak na izmenu pozitivnih propisa i dozvolu
širenja upotrebe ovih organizama.
Semenarstvo Republike Srbije je veoma značajna grana poljoprivredne proizvodnje
kojom se u državu slivaju velike količine novca od prodaje semena domaćih selekcija.
Povrtarstvo je samo jedan mali segment ove proizvodnje, ali veoma bitan, kako za
domaće proizvođače –farmere koji se sve podložniji svetskim trendovima nastupa na
organizovanim tržištima a koji zahtevaju određene karakteristike gajenih sorti, tako i za
konzumente povrća. Ovi zahtevi savremenog tržišta najčešće su u suprotnosti sa
kvalitetom.
Današnje semenarstvo Srbije se odvija u državnom i privatnom sektoru. Iako
proizvodnja semena može podmiriti domaće potrebe, izvesna količina semena se
nabavlja uvozom. Ovaj uvoz je postojao i u vreme zatvorenog tržišta SFRJ, te su
smenske kompanije navikle na tržišnu utakmicu. Problem, a iskazala ga je i Evropska
Unija svojim zakonima, jeste da jedan deo povrtara, osim za organsku (dinamičku, bio
i dr proizvodnju), koriste određene količine semena povrća iz sopstvene merkantilne
proizvodnje. Ovakvi usevi ostvaruju niske prinose kako zbog kvaliteta semena (sortna
čistoća, klijavost), tako i zbog zdravstvene ispravnosti semena
Sortiment povrća koji nastaje u Republici Srbiji stvaran je u agroekološkim
uslovima Balkanskog poluostrva te je zato i našlo je tržište širom Balkana, a u poslednje
vreme, i Evrope. Cilj ovog rada je da se iskaže učešće u proizvodnji pojedinih
povrtarskih vrsta izraženo po površinama i u količinama Instituta za povrtarstvo d.o.o u
semenarskoj proizvodnji Srbije. Istraživani ciklus je obuhvatao 4 godine i u njemu je
proizvedeno seme povrća na 956 ha 2007 (64.9 ha), 1152 (137) 2008. godine, 1219 ha
(242.1ha) 2009. godine i 976 ha (198.7 ha) 2010. godine
A STUDY OF THE USE OF MIXED REALITY FOR CAPTURING HUMAN OBSERVATION AND INFERENCES IN PRODUCTION ENVIRONMENTS
Augmented and mixed reality is already considered as needful technology of the modern production systems. It is primarily employed to virtualize proper digital content, mainly related to 3D objects, into the human visual field allowing people to visualize and understand complex spatial shapes, their mutual relations, and positioning. Yet, the huge potential of the technology is waiting to be revealed in its usage for collecting and recording human observations and inferences about the context of the production environment. Its bi-directional interface makes it the most direct and the most efficient knowledge capturing means to date. The paper presents the challenges and benefits that come from the usage of a conceptual interface of an mixed reality application that is designed to collect data, semantics and knowledge about the production context directly from the man-in-process. As a production environment for the development, implementation, and testing of mixed reality applications for this purpose, various processes for the assembly and maintenance of medium-voltage equipment were used
Izbor genotipova paradajza na tolerantnost prema suši
Screening collections aimed to make the selection of genotypes tolerant to drought
in the vegetative stage of intensive growth of plants, which would start the program
selection to obtain recombinant genotypes according to the abiotic factor. The criteria
for screening were the diversity of genotypes for the number of sheets of the first flower
branches and number of flower branches into the optimal mode of irrigation regime and
reduced by 40 % . On the basis of the analysis genotypes: the number of leaves to the
first floral branch G 106, 114, 121 and 122 ( 0 % ), and genotype G102, 114, and 125
for the characteristic number of lateral branches.Paradajz je široko prilagođen različitim podnebljima gajenja, međutim,
njegov rast i razviće je prilično osetljiv na različite uslove spoljne sredine, uključujući
salinitet, sušu, vlagu, ekstremne temperature, mineralne toksičnosti, kao i zagađenje
životne sredine. Postoji ograničenje genetske varijacije za abiotičku toleranciju na stres
u okviru kultivisanih vrsta i većina komercijalnih sorti se smatraju umereno do veoma
osetljive na različite vrste stresa. Ispitivanje je izvršeno na 11 genotipa paradajza
poreklom iz populacije domaćih i odomaćenih genotipova prikupljenih iz Srbije, a
pripadaju kolekciji paradajza Instituta za povrtarstvo u Smederevskoj Palanci. Skrining
kolekcije imao je za cilj da se izvrši izbor genotipova tolerantnih na sušu u vegetativnoj
fazi intenzivnog porasta biljaka, čime bi se započeo program selekcije na dobijanje
rekombinovanih genotipova prema ovom abiotskom faktoru. Kriterijumi za skrining bili
su divergentnost genotipova za broj listova do prve cvetne grane i broj cvetnih grana u:
optimalnom režimu navodnjavanja i redukovanom režimu za 40%. Na osnovu izvedenih
analiza izdvojeni su genotipovi: za broj listova do prve cvetne grane G 106, 114, 121 i
122 (0%), kao i genotipovi G102, 114, i 125 za osobinu broja bočnih grana koji će
predstavljati bazu za dobijanje rekombinovanih genotipova i početak selekcije na
otpornost na sušu

A giant exulcerated phyllodes breast tumor a case report
© 2020, University of Kragujevac, Faculty of Science. All rights reserved. Phyllodes tumors of the breast can be benign, malignant, or borderline. Benign and borderline tumors are rare tumor types that have a positive outlook and high survival rate, while the risk of recurrence is typical for malignant breast tumors. Giant phyllodes tumors are larger than 10 cm in diameter and demand a serious diagnostic and treatment approach. In this study we present a case of a female patient treated for an exulcerated breast carcinoma-a giant borderline phyllodes tumor of the breast. The patient presented to the department for the right breast lump with ulcerated skin and nipple abnormalities. The core biopsy was performed and the patient was diagnosed with a benign tumor. Simple mastectomy was performed and final histopathological report revealed a borderline phyllodes tumor. Diagnosis and treatment of a giant phyllodes tumor remain a great challenge for the surgeons. Establishing the preoperative diagnosis based on histopathological findings is imperative to disease management. Surgery is the mainstay of treatment and mastectomy has been the traditional procedure; in cases where suspicious findings in the axilla are revealed, radical mastectomy is performed and the axilla is to be dissected
ODREĐIVANJE HEMIJSKOG SASTAVA RAZLIČITIH EKSTRAKATA ČUVARKUĆE
Sempervivum tectorum has a similar effect as aloe vera, which is known in
the treatment of various skin diseases. This herb is considered one of the safest
remedies for a wide range of skin diseases. Due to its anti-inflammatory and
antiseptic properties, it also serves as an excellent first aid for burns, stings and bites,
because it provides quick relief and calming. Freshly squeezed juice from the leaves
of the houseplant is used in the treatment of nervous disorders, epilepsy and restless
dreams. The leaves are edible and can be used as an addition to salads or stews. They
are not particularly tasty, but as they are rich in water, they can be put in a juicer
together with other fruits or vegetables and become a refreshing drink. It is used in
folk herbal medicine and as a medicine.
The aim of this study was to determine the moisture content, total extracted
substances, extract density, vitamin C, organic acids and proteins in house extracts.Publishe
