Photosynthesis under artificial light

Biljkama je za normalan rast i razvoj, te proizvodnju organske tvari potrebna sunčeva energija. U sustavima za kontrolirani uzgoj biljaka prirodna svijetlost se nadopunjuje ili u potpunosti zamjenjuje umjetnim izvorima osvjetljenja. Tradicionalni izvori svijetlosti, poput HPS i MH, nisu dovoljno učinkoviti i generiraju puno operativne topline pa se javlja potreba za novim održivim i energetski učinkovitijim izvorom osvjetljenja. LED svjetla inovativni su izvor umjetnog osvjetljenja za biljke koji otvaraju mogućnost ciljanog manipuliranja metaboličkim reakcijama kako bi se optimizirao uzgoj i proizveli visokokvalitetni proizvodi. Potpuni fiziološki odgovor različitih biljnih vrsta na osvjetljenje LED svjetlima još uvijek nije u potpunosti poznat.Sunlight is necessary for the production of organic matter and normal growth and development of plants. Natural light in systems for protected cultivation is supplemented or replaced with artificial sources of light. Traditional light sources, like HPS or MH, are not very efficient and usually generate high radiant heat. Therefore, the need for development of sustainable and energy efficient sources of artificial light is present. Light emitting diodes (LED) are innovative sources of artificial light that provide the possibility of manipulation of certain metabolic pathways in order to produce nutritive valuable food in higher quantities. Still, physiological responses of plants to LED light is not fully understood

UTJECAJ DRUŠTVENO ODGOVORNOG POSLOVANJA NA KONKURENTSKU PREDNOST HOTELA LAV : Diplomski rad

Koncept DOP-a te njegovo tumečenje i definiranje razlikuje se u mnogo aspekata. Može ovisiti o zemlji, gospodarskom sektoru, vrsti i veličini tvrtke, vlasničkoj strukturi itd. Dok ga jedni smatraju načinom za postizanje konkurentske prednosti, za druge DOP predstavlja odgovor na rastuće potrebe glavnih dionika (zaposlenici, ulagači, potrošači, aktivisti i stručnjaci za zaštitu okoliša). Konkurentska sposobnost, a samim time i postizanje konkurentske prednosti je bitna stavka strateškog djelovanja poduzeća.. Danas konkurentnost poduzeća sve više proizlazi iz njegovih zaposlenika, korporativne kulture, sustava koji potiče inovacije te poslovnog vodstva koje potiče i podržava stalne promjene. U Europi ali i širom svijeta raste broj kompanija koje sve više promoviraju svoju strategiju društvene odgovornosti. Na taj način pokušavaju odgovoriti ne samo na različite ekonomske i društvene pritiske već i one koje se tiču zaštite okoliša. Primjenjivanje DOP-a u različitim segmentima poslovanja poduzeća ostvaruju konkurentnu prednost koja utječe da poduzeće stvori jedinstvenu percepciju na tržištu koja služi u izgradnji reputacije. Temeljni cilj ovog istraživanja je bio utvrditi razinu primjene koncepta DOP-a u hotelu Lav, odnosno ispitati da li primjena DOP-a utječe na konkurentsku prednost i uspjeh navedenog poduzeća. U tu svrhu proveden je anketni upitnik 30 zaposlenika hotela Lav kojim se potvrđuje da hotel u svom poslovanju vodi računa o interesima svih dionika, te primjenjuje koncept društveno odgovornog poslovanja. Primjena ovog koncepta u uskoj je i pozitivnoj vezi s ostvarenjem konkurentske prednosti.The concept of CSR and its interpretation and definition differ in many respects. It can depend on land, economy, types and sizes of businesses, ownership structures, etc. While the only real thing to achieve competitive advantage, for others CSR is to respond to the growing needs of large stakeholders (employees, employees, consumers, activists and environmentalists) . Competitive ability, over time and achieving competitive advantage is an essential element of strategic enterprise performance. Today, competing businesses are increasingly producing from their employees, corporate culture, systems that drive innovation in business waters that encourage and support constant change. In Europe and around the world, a growing number of companies are increasingly promoting their CSR strategy. In this way, they are trying not only to respond to different economic and social pressures, but also to one concerning environmental protection. The application of CSR in the broader business segment of the enterprise has achieved a competitive advantage that affects entrepreneurship and creates a unique perception in the market that serves to build reputation. The basic aim of this research was to confirm the existence of CSR in the Lav Hotel, ie to test that CSR implementation will be successful on the competitive advantages and success of the visited companies. To this end, it was verified that a questionnaire of 30 employees of Hotel Lav confirms that the hotel took into account the interests of all stakeholders in its operations, while using the concept of socially responsible business. The application of this concept is a close and positive connection with the realized competitive advantages

Speech and language abilities in a boy with partial trisomy 7q

Parcijalna trisomija 7q (7q) rijetka je genetička pogrješka defi nirana duplikacijom dugog kraka 7. kromosoma. Karakterizirana je višestrukim teškoćama u spoznajnom i motoričkom razvoju, karakterističnim obilježjima fenotipa i teškoćama učenja. Klinička slika je vrlo varijabilna i ovisi o količini dupliciranog segmenta. Cilj ovog rada bio je standardiziranim mjerenjima ispitati opseg receptivnog rječnika, razumijevanje gramatike, usvojenost predvještina čitanja i pisanja, govorno-motoričke i pripovjedne sposobnosti te kakvoću glasa dječaka s parcijalnom trisomijom 7q. Dječakova dob je bila 7 godina i 10 mjeseci. Obradom podataka utvrđeno je da dječak ima smanjen opseg receptivnog rječnika, postiže umjereno nizak rezultat na TROG-2:HR testu razumijevanja gramatike, govorno-motoričke sposobnosti su narušene kao i kakvoća glasa te su vidljive teškoće u grafomotoričkoj izvedbi i zadatcima vizualne percepcije. Dječak ima usvojene neke predvještine čitanja i pisanja. Uredno postignuće pokazuje na varijablama raščlambe rečenice na riječi, varijabli fonemske svjesnosti i fonološkog imenovanja velikih i malih slova.Partial trisomy on chromosome 7 (7q) is a rare condition resulting from duplication of the 7q long arm. It is usually associated with delayed psychomotor development, characteristic phenotypic features and profound learning disabilities. The clinical picture is highly variable and depends on the size of duplicated segments. The aim of this study was to examine the range of receptive vocabulary and understanding of grammar, acquisition of early reading and writing skills, speech and motor skills, voice quality and narrative abilities in a boy with partial trisomy 7q. The child’s chronological age during the study period was 7 years and 10 months. Data analysis showed that the boy had a reduced range of receptive vocabulary and achieved low scores on the test of grammar reception (TROG-2: HR). His speech and motor skills were impaired, as well as his voice quality. The boy had acquired some early reading and writing skills. He showed good results in the variables of breaking down sentences to words, variable of phonemic awareness and phonological naming of uppercase and lowercase letters

USPJEŠNO OSTVARENJE POTOMSTVA NAKON KRIOPREZERVACIJE SPERMIJA ZBOG MA- LIGNE BOLESTI TESTISA

Nowadays the number of couples who fail to conceive naturally is constantly increasing. There are many reasons for infertility and the most common one is the age of the mother. Medically assisted reproduction also enables people suffering from malignant diseases to freeze their gametes to have offspring later. Two main forms of infertility treatments include intrauterine insemination and in vitro fertilization.U suvremenom svijetu učestalost parova koji ne uspijevaju na prirodan način ostvariti potomstvo u stalnom je porastu. Razlozi za neplodnost su mnogi, a najčešći jest visoka dob majke. Medicinski pomognuta oplodnja također omogućuje da osobe koje boluju od malignih bolesti zamrznu spolne stanice te kasnije ostvare potomstvo. Dva temeljna oblika liječenja neplodnosti obuhvaćaju intrauterinu inseminaciju i izvantjelesnu oplodnju

The Role of Social Support and Insight into the Self–Stigmatization of Persons Suffering from Schizophrenia

Cilj istraživanja bio je ispitati prediktivni doprinos socijalne podrške i uvida samostigmatizaciji te njezinim dimenzijama kod osoba oboljelih od shizofrenije. Hijerarhijske regresijske analize pokazale su statistički značajan doprinos uvida i socijalne podrške samostigmatizaciji te nekim njezinim dimenzijama kod osoba oboljelih od shizofrenije. Niža socijalna podrška i viši uvid predviđaju višu samostigmatizaciju, višu otuđenost, više prihvaćanje stereotipa te više socijalno povlačenje. Niža socijalna podrška predviđa više iskustvo diskriminacije.Schizophrenia is associated with various beliefs that are most often associated with negative labeling, called stigma. Some of the wrong beliefs are that schizophrenia is incurable and dangerous and that patients are aggressive, incapable of life, decision making and work. Many patients with schizophrenia accept the stigmatizing attitudes of the society as personally relevant, leading to the process of self–stigmatization, which prevents them from getting in touch with people, encouraging feelings of shame, helplessness and guilt and prevents their progress. Studies confirm that patients with good social support have better prognosis for the disease and that those with lower social support show higher self–stigmatization. Studies have shown that insight can also be related to the level of self–stigmatization. Higher insight is associated with higher self–stigmatization, higher alienation, higher stereotype endorsement, higher discrimination experience and higher social withdrawal. In the available literature they have not studied together social support, insight and self– stigmatization on a sample of patients with schizophrenia. The aim of this study was to examine the predictive contribution of the social support and insight for self–stigmatization and its dimensions of patients with schizophrenia. This cross–sectional study was conducted on 74 patients with schizophrenia. The participants completed the Internalized Stigma of Mental Illness Scale, Scales of Perceived Social Support, A self–report Insight Scale for psychosis and General Data Questionnaire, by the paper–pencil technique. Hierarchical regression analyses have shown that social support and insight have a statistically significant contribution to self–stigmatization and some of its dimensions in patients with schizophrenia. Lower social support and higher insight predict higher self–stigmatization, higher alienation, higher stereotype endorsement and higher social withdrawal. Lower social support predicts higher discrimination experience

The Impact of Osteoporosis on Dental Health in Women Older than 45 Years

Svrha istraživanja: Osteoporoza i gubitak zuba zdravstveni su problemi koji pogađaju stariju populaciju, osobito žene. Oboje znatno utječe na kvalitetu života. Svrha ovog istraživanja bila je ustanoviti postoji li statistički značajna povezanost mineralnog statusa kostiju u području kuka i slabinske kralježnice s brojem zuba i KEP-indeksom kod žena u dobi iznad 45 godina. Materijali i metode: Ovo presječno istraživanje obuhvatilo je 91 ženu stariju od 45 godina. Svima su digitalno panoramski snimljene čeljusti, a tehnologijom DEXA utvrđena je mineralna gustoća slabinske kralježnice (L1 – L4) i proksimalnog femura. Tijekom kliničkog pregleda usne šupljine zabilježen je zubni status. Broj zuba izračunat je s pomoću panoramske snimke. Uzorak je podijeljen u dvije skupine ovisno o vrijednostima gustoće kostiju na nalazu DEXA. Rezultati: Rezultati statističke analize pokazali su kako nije bilo značajne razlike u distribuciji ukupnog broja zuba (t=-0,171, P>0,05) između dviju skupina u sklopu analiziranog uzorka. Također nije bilo statistički značajne razlike u vrijednosti KEP-indeksa i broja zdravih zuba. Statistička analiza pokazala je značajnu korelaciju između dobi i broja zuba (r=-0,26; P=0,005), a korelacija između razine obrazovanja i broja zuba bila je još izrazitija. Zaključak: Na osnovi dobivenih rezultata zaključujemo da zubni status i gubitak zuba kod žena u dobi iznad 45 godina nisu povezani s mineralnom gustoćom kostiju. No potrebna su daljnja istraživanja kako bi se ispitao utjecaj osteoporoze na oralno zdravlje, s osobitim naglaskom na promjene u čeljusnim kostima.Objectives: Osteoporosis and tooth loss are health problems that affect older population, especially women. Both of them have great impact on life quality. The aim of this study was to determine the relationship between the mineral status in the hip and lumbar spine region and the number of teeth present and DMTF index in women older than 45 years. Materials and Methods: This cross-sectional study included 91 women older than 45 years. Digital panoramic radiographs were taken and bone mineral density was determined for the lumbar spine region (L1-L4) and the proximal femur by DEXA technology. Dental status was recorded by clinical examination. Number of teeth was counted on radiographs. Subjects were divided into two groups according to their DEXA report. Results: There was no significant difference in distribution of total teeth number (t=-0.171, p>0.05) between two groups of the analyzed sample. There was no significant difference between the two groups according to DMFT index and number of sound teeth. Statistical analysis showed significant correlation of the age and the number of present teeth (r=-0.26; P=0.005). The correlation of educational level and the number of present teeth was even stronger. Conclusion: We conclude that dental status and tooth loss in women older than 45 years are not related to BMD. Further studies are needed to assess the role of osteoporosis in oral health with emphasis on oral bone changes

Association of NLRP1 Coding Polymorphism with Lung Function and Serum IL-1β Concentration in Patients Diagnosed with Chronic Obstructive Pulmonary Disease (COPD)

Chronic obstructive pulmonary disease (COPD) is a chronic disease characterized by a progressive decline in lung function due to airflow limitation, mainly related to IL-1β-induced inflammation. We have hypothesized that single nucleotide polymorphisms (SNPs) in NLRP genes, coding for key regulators of IL-1β, are associated with pathogenesis and clinical phenotypes of COPD. We recruited 704 COPD individuals and 1238 healthy controls for this study. Twenty non-synonymous SNPs in 10 different NLRP genes were genotyped. Genetic associations were estimated using logistic regression, adjusting for age, gender, and smoking history. The impact of genotypes on patients’ overall survival was analyzed with the Kaplan–Meier method with the log-rank test. Serum IL-1β concentration was determined by high sensitivity assay and expression analysis was done by RT-PCR. Decreased lung function, measured by a forced expiratory volume in 1 s (FEV1% predicted), was significantly associated with the minor allele genotypes (AT + TT) of NLRP1 rs12150220 (p = 0.0002). The same rs12150220 genotypes exhibited a higher level of serum IL-1β compared to the AA genotype (p = 0.027) in COPD patients. NLRP8 rs306481 minor allele genotypes (AG + AA) were more common in the Global Initiative for Chronic Obstructive Lung Disease (GOLD) definition of group A (p = 0.0083). Polymorphisms in NLRP1 (rs12150220; OR = 0.55, p = 0.03) and NLRP4 (rs12462372; OR = 0.36, p = 0.03) were only nominally associated with COPD risk. In conclusion, coding polymorphisms in NLRP1 rs12150220 show an association with COPD disease severity, indicating that the fine-tuning of the NLRP1 inflammasome could be important in maintaining lung tissue integrity and treating the chronic inflammation of airways
