    The effects of different flour additives on the Farinograph. Alveograph and Extensograph properties of BL 80 flour were evaluated. The purpose of the study was to evaluate the way and degree of their influences to establish a subsequent research on their possible substitution by natural ingredients. We found that the effects of flour additives can be measured by rheologic methods and the extends of changes determined by different methods are similar

    Use of Sections in the Engineering Practice

    Thanks to 3D CAD modelling software the role of sections has been grown significantly. In this article we discuss the increasing role of sections. First we present some practical applications such as a section of a track and wheel and we also show how they can be used for mechanical calculations through an example of a shaft weakened with a keyway. The principle of additive manufacturing is also based on sections. Finally sections can be also used at optimizing parts, but in this paper we discuss only the case of shape optimizing

    The Role of Salt Form and Concentration on the Rheological Properties of Bakery Products

    The effect of different salt forms and concentrations were evaluated on the rheological properties of dough made from wheat and rye flours. Our aim was to investigate that how does the sodium chloride change the properties of gluten network and therefore the structure of bakery products and what effects can be experienced when it is substituted by other organic and inorganic salts. Different rheological tests were used to monitor the effects on dough (Farinograph, Alveograph and Extensigraph tests) and on the end-product (texture analysis, sensory analysis). It was found that all the salt forms significantly influenced the rheological parameters of dough and not the sodium chloride addition had the most favourable effect in every case

    Increasing Role of Sections Caused by 3D Modelling

    In the last years the role of sections has been grown significantly thanks to solid modelling. Earlier objects were defined by 2D drawings, while cuts or sections were only used for representing their inner parts in case of need. After a short review of types and rules of section drawings we discuss the different ways how objects can be defined with their sections using 3D modelling software.  Finally we discuss that creating solid objects can be used not only in technical but as well as in medical practise. To illustrate them we show examples for both cases: a pump and a human skull

    Mucocele of the appendix: An unusual cause of lower abdominal pain in a patient with ulcerative colitis

    Get PDF
    The authors report the case of a 60-year-old male patient. In November 2001 he developed intestinal symptoms of bloody diarrhea and abdominal pain. Colononoscopy and biopsy established the diagnosis of ulcerative colitis (proctosigmoiditis). The disease activity was moderate at the beginning. No significant laboratory alterations were found (including CEA, CA19-9), and mesalazine was started orally. He was in remission until November 2003, when he was admitted to our Outpatient Clinic for upper and right lower abdominal pain and bloody diarrhea. Colonoscopy found proctosigmoiditis with a moderate activity, gastroscopy revealed chronic gastritis, laboratory data was normal. Treatment was amended with mesalazine clysma and methylprednisolone (16 mg) orally. Symptoms ameliorated; however, right lower abdominal pain persisted. US and CT examination demonstrated a pericecal cystic mass (11 cm x 3.5 cm). At first pericecal abscess was suspected, as the previous US examination (6 mo earlier) had revealed normal findings. Fine needle aspiration was performed. Cytology confirmed the diagnosis of mucocele. The patient underwent partial cecum resection and extirpation of the mucocele. He recovered well and the final histology revealed a cystadenoma of the appendix. Follow up was started. The patient is now free of symptoms. Although primary adenocarcinoma of the appendix is uncommon, the authors emphasize that preoperative diagnosis of an underlying malignancy in a mucocele is important for patient management; however, it is difficult on imaging studies

Az elemzĂ©s sorĂĄn azt talĂĄltuk, hogy a hajlĂ©ktalan helyzetben lĂ©vƑ emberek körĂ©ben a koldulĂł-kukĂĄzĂł hajlĂ©ktalanok egy markĂĄnsan eltĂ©rƑ csoportot alkotnak mind lakhatĂĄsukat, megĂ©lhetĂ©sĂŒket, szocio-demogrĂĄfiai hĂĄtterĂŒket, mind mindennapi Ă©letĂŒket tekintve. Szinte minden dimenziĂłban hĂĄtrĂĄnyosabb kĂ©pet mutatnak mĂ©g a többi hajlĂ©ktalanhoz kĂ©pest is. ElemzĂ©sĂŒnk azt mutatja, hogy ezekkel az emberekkel az utcai szolgĂĄlatokon Ă©s egyes nappali melegedƑkön kĂ­vĂŒl a hajlĂ©ktalanellĂĄtĂĄs bentlakĂĄsos intĂ©zmĂ©nyeinek alig van kapcsolata.

    Az 1999 Ăłta minden Ă©vben lebonyolĂ­tott „FebruĂĄr Harmadika” orszĂĄgos hajlĂ©ktalan adatfelvĂ©tel nem csak arra vilĂĄgĂ­t rĂĄ, hogy MagyarorszĂĄgon folyamatosan nƑ a „cigĂĄnyok” rĂ©szarĂĄnya a hajlĂ©ktalanok körĂ©ben, hanem arra is, hogy ez egyĂŒtt jĂĄr a hajlĂ©ktalan nĂ©pessĂ©g belsƑ ĂĄtrĂ©tegzƑdĂ©sĂ©vel, a hĂĄtrĂĄnyok tovĂĄbbi összekapcsolĂłdĂĄsĂĄval. A magyarorszĂĄgi cigĂĄnysĂĄg etnikai, iskolai, munkaerƑpiaci kirekesztettsĂ©ge immĂĄr a hazai hajlĂ©ktalansĂĄg lĂ©nyeges összetevƑjĂ©vĂ© vĂĄlt. Ezzel pĂĄrhuzamosan a kutatĂĄs arra is rĂĄmutat, hogy a nĂ©pessĂ©g egĂ©szĂ©hez kĂ©pest a hajlĂ©ktalanok körĂ©ben jĂłval magasabb a sokgyerekesek, illetve a sokgyerekes csalĂĄdbĂłl szĂĄrmazĂłk arĂĄnya, e csalĂĄdok esetĂ©ben jelentƑsen nagyobb a (lakhatĂĄsi) krĂ­zisek elƑfordulĂĄsĂĄnak a kockĂĄzata Ă©s ezzel egyĂŒtt jĂĄr, hogy e csalĂĄdok körĂ©ben immĂĄr generĂĄciĂłkon keresztĂŒl öröklƑdik a hajlĂ©ktalan lĂ©thelyzet. E kĂ©t tendencia erƑsĂ­ti is, de egyben ki is egĂ©szĂ­ti egymĂĄst: a hazai hajlĂ©ktalansĂĄg szĂĄmottevƑ eredƑjĂ©vĂ© vĂĄlt mind a cigĂĄnysĂĄg, mind ĂĄltalĂĄban a sokgyerekes csalĂĄdok egy rĂ©szĂ©nek pauperizĂĄlĂłdĂĄsa, iskolai Ă©s munkaerƑpiaci kirekesztettsĂ©ge

    „Így kallĂłdunk el szĂ©pen egymĂĄs utĂĄn”. Állami gondozottak voltak, ma hajlĂ©ktalanok

    A 2020. Ă©vi „FebruĂĄr Harmadika” orszĂĄgos adatfelvĂ©tel szerint a vĂĄlaszadĂł hĂ©tezer hajlĂ©ktalan ember közĂŒl minden ötödik ember a gyerekkorĂĄt rĂ©szben vagy egĂ©szen ĂĄllami gondozĂĄsban töltötte. ÁltalĂĄban nem közvetlenĂŒl, hanem vĂĄltozatos nem-hajlĂ©ktalan periĂłdusokat követƑen vĂĄlnak hajlĂ©ktalannĂĄ a volt ĂĄllami gondozottak. Az ĂĄllami gondozotti hĂĄttĂ©r – a hajlĂ©ktalan Ă©lethelyzeten belĂŒl is – tovĂĄbbi sĂșlyos hĂĄtrĂĄnyokkal kapcsolĂłdik össze: a többiekhez kĂ©pest alacsonyabban iskolĂĄzottak, igen magas a pszichiĂĄtriai betegek Ă©s a romĂĄk arĂĄnya a körĂŒkben, munkaerƑpiaci pozĂ­ciĂłjuk lĂ©nyegesen rosszabb (igen sokan kukĂĄzĂĄsbĂłl, koldulĂĄsbĂłl Ă©lnek), Ă­gy jövedelmĂŒk is alacsonyabb a többiekĂ©nĂ©l.
