Influence of mictrostructure features on the corrosion behaviourof AZ91 alloy in chloride media

The influence of the microstructure of as-cast AZ91 magnesium alloy, which applied to solution annealing treatment and ageing treatment respectively, was evaluated in terms of its corrosion behaviour in 0.1 M NaCl solution at room temperature. The corrosion process was monitored by electrochemical impedance spectroscopy (EIS) and the surface was characterized by scanning Kelvin probe force microscopy (SKPFM). The extent of corrosion damage was dependent on the microstructure. Surface potential maps indicated that, the surface potential of α-matrix is more positive than surface potential of β phase

PITTING CORROSION OF AISI 316Ti STAINLESS STEEL WITH POLISHED SURFACE

AISI 316Ti is Cr–Ni–Mo austenitic stainless steel with the high Pitting Resistance Equivalent Number (PREN). The effect of the surface finishing by polishing on the pitting corrosion resistance was tested in aggressive 5% FeCl3 solution. The immersion tests were curried out at the temperature 30, 50, 80 °C. The electrochemical cyclic potentiodynamic tests were carried out in the same solution at temperature 30 and 50 °C. The evaluation of the corrosion resistance arose from the comparison of the results of the immersion and the cyclic potentiodynamic tests

Cilj: Cilj ovog istraživanja bio je utvrditi učestalost infekcija povezanih s centralnim venskim kateterom (CVK) u bolesnika na parenteralnoj prehrani u Klinici za dječje bolesti Zagreb u periodu od 24 godine, s posebnim naglaskom na kućnu parenteralnu prehranu. ----- Metode: Retrospektivno su analizirani podaci sve djece na parenteralnoj prehrani (N= 78) liječene u našem centru u periodu od 1989-2013. godine. ----- Rezultati: Parenteralna prehrana uvedena je u srednjoj dobi of 1,2 godine (raspon od 6 dana-17,6 godina), ukupno je bilo 45 dječaka i 33 djevojčice. Od 78 bolesnika njih 15 (19.2%) primalo je kućnu parenteralnu prehranu nakon otpusta iz bolnice. Ukupno je upotrebljeno 107 CVK (prosječno1,37/bolesniku). Ukupno vrijeme CVK iznosi 23 880 dana odnosno 232,2 dana/CVK. Tijekom promatranog razdoblja zabilježeno je 46 sepsi uzrokovanih CVK (1,9/1000 dana parenteralne prehrane). Na kućnoj parenteralnoj prehrani broj septičkih komplikacija značajno je manji u odnosu na bolničku ( 0,85/1000 vs 5,8/1000 dana parenteralne prehrane; p < 0.001). Ukupno 17 centralnih venskih katetera izvađeno je zbog sepsi uzrokovanih CVK. Tijekom navedenog razdoblja od komplikacija parenteralne prehrane umrlo je ukupno četvero djece (5,1% ; 0,17 smrtnih ishoda na 1000 dana parenteralne prehrane). Dvoje djece umrlo je od posljedica sepse (jedno na kućnoj i jedno na bolničkoj parenteralnoj prehrani). Drugo dvoje djece umrlo je od zatajenja jetre uzrokovanog parenteralnom prehranom. ----- Zaključak: U zaključku možemo reći da je učestalost infekcija povezanih s CVK izrazito niska i u bolničkoj i kućnoj parenteralnoj prehrani čemu doprinosi dobro medicinsko zbrinjavanje i sestrinska skrb ovih bolesnika.Background & aims: The aim was to assess the rate of central venous catheter (CVC) related complication, mostly sepsis in patients on parenteral nutrition (PN) at our hospital center during a period of 24 years with special emphasizes on hom PN (HPN). ----- Methods: Data on all children who received PN for more than 4 weeks (n = 78) in our tertiary hospital center during the period of 24 years (from 1989-2013), were retrospectively analyzed. ----- Results: The mean age at the time of introducing the PN was 1.2 years (range 6 days to 17.6 years), male/female ratio 45/33. Out of these 78 patients, 15 (19.2%) patients continued HPN after discharge from the hospital. Altogether 107 CVCs were used (mean 1.37 per patient) and total CVC time was 23,880 days, which makes 232.2 days per CVC. During the study period, there were 46 CVC related sepsis episodes (1.9/1000 days of PN). Total number of septic episodes was significantly lower in HPN compared to hospital PN (0.85/1000 vs. 5.8/1000 days of PN; P < 0.001). Septic episodes led to removal of 17 (15.9) CVCs. Althogheter 4 (5.1%) patients died due to PN related complication (0,17 deaths on 1000 PN days); two patients from CVC related sepsis (one on HPN and one at hospital) and two patients died due to intestinal failure associated liver disease (IFALD). ----- Conclusion: The rate of CVC related sepsis in our PN cohort was exceptionally low in both hospital and home setting indication good medical management and nursing care

Analysis of the Association Between Topics in Online Documents and Stock Price Movements

This paper aims at discovering the topics hidden in the newspaper articles that have an impact on movements of stock prices of the corresponding companies. Document topics are characterized by combinations of specific words in documents and are shared across a document collection. We describe the process of discovering the topics, the creation of a mapping of the topics to stock price movements, and quantifying and evaluating the results. As the method for finding and quantifying the association, we use machine learning-based classification. We achieved an accuracy of stock price movement predictions higher than 70 %. A feature selection procedure was applied to the features characterizing the topics in order to facilitate the process of assigning a label to the topic by a human expert.O

Projektiranje stanice za automatsku montažu okova za prozore

Ovaj rad zasniva se na ideji o poboljšanju proizvodnog procesa izrade prozora, u smislu uštede na vremenu i pouzdanosti, što se očituje i u konačnoj kalkulaciji troškova gotovog proizvoda.Da bi prozor mogao funkcionirati, potrebno je ugraditi okov. Upravo taj skup proizvoda omogućava otvaranje i zatvaranje prozora dugoročno, pouzdano i sigurno. Kod konvencionalnog načina okivanja koji se prakticira gotovo u svim proizvodnjama, okov se ugrađuje na gotovo krilo i okvir prozora. Ovisno o dimenziji krila u utoru, u koji se ugrađuje okov, odabiru se pojedini dijelovi. U malim proizvodnim pogonima bez automatiziranih proizvodnih linija, okvir i krilo se okivaju na jednom radnom mjestu, a okivanje vrši jedan radnik. U tvornicama koje su opremljene proizvodnim linijama, krilo i okvir se okivaju na zasebnom radnom mjestu, a okivanje obavljaju dva radnika. Postoji okov koji omogučava okivanje krila i okvira prije njegovog sastavljanja, pa se okov ugrađuje u slobodni štap profila tijekom procesa izrade krila.Slobodni štap se okiva na mjestu gdje izlazi iz obradnog centra, a okivanje vrši jedan ili više radnika. U svrhu povećanja produktivnosti, projektirana je automatska stanica za montažu okova koja se sastoji od manipulatora i automata za posluživanje. Kinematika koju manipulator mora zadovoljiti, kao i točnost ponavljanja i brzinu gibanja, osnovni su zahtjevi za točno provođenje procesa ugradnje okova. Prilikom procesa ugradnje, profil miruje, dok manipulator odrađuje softverski zadano pozicioniranje okova, utiskivanje u zadani utor na profilu i uvrtanje vijaka. U ovom slučaju radi se o kinematičkoj strukturi robota s tri stupnja slobode.Gibanje koordinata manipulatora po svim osima, x, y, z, je translacija. Sastavni dio stanice za montažu je automat za posluživanje okova, čiji je zadatak kontinuirana dobava pozicija koje se ugrađuju, kao i njihovo ispravno pozicioniranje prije samog hvatanja prihvatnicom. Kako bi se izvršila usporedbe vremena , procijenjeno je vrijeme svake operacije automatskog i ručnog okivanja, a rezultati su prikazani u tablicama Usporedbom tih vremena dobiveni su rezultati koji opravdavaju automatizaciju postupka okivanja, uz optimalni kapacitet proizvodnje od 480 prozora u smjeni i povećanu produktivnost od 33,3%

Sentiment individuálnych investorov a verejne obchodované korporácie s vysokou tržnou kapitalizáciou

This thesis studies the relation between the sentiment of individual investors and large-cap publicly traded corporations. The sentiment of individual investors is proxied by social media Facebook. In terms of investment decision making, the web or social media are main sources of information for individual investors. Due to technological development, the number of individual investors is growing. According to the behavioral finance theory, individual investors are considered as less rational agents that react to less rational information (emotions, social mood or opinion) irrelevant to fundamentals of securities. The impact of sentiment is studied at the level of volume of trade (liquidity) and stock prices. The results show a negative link between growing social media activity and volume of trade/stock prices. Delivered results can be considered as causal due to nature of employed data and presence of a weekend effect
