Evaluation of food additives on the rheologic properties of winter wheat flours
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
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
A hajléktalanvilåg peremén
ĂrĂĄsunkban a koldulĂł, gyƱjtögetĆ, kukĂĄzĂł hajlĂ©ktalan emberek jellemzĆit elemezzĂŒk hĂșsz Ă©v empirikus adatfelvĂ©telei alapjĂĄn. Az elemzĂ©s sorĂĄn azt talĂĄltuk, hogy a hajlĂ©ktalan helyzetben lĂ©vĆ emberek körĂ©ben a koldulĂł-kukĂĄzĂł hajlĂ©ktalanok egy markĂĄnsan eltĂ©rĆ 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 melegedĆkön kĂvĂŒl a hajlĂ©ktalanellĂĄtĂĄs bentlakĂĄsos intĂ©zmĂ©nyeinek alig van kapcsolata.

Az 1999 Ăłta minden Ă©vben lebonyolĂtott âFebruĂĄr Harmadikaâ orszĂĄgos hajlĂ©ktalan adatfelvĂ©tel nem csak arra vilĂĄgĂt rĂĄ, hogy MagyarorszĂĄgon folyamatosan nĆ a âcigĂĄnyokâ rĂ©szarĂĄnya a hajlĂ©ktalanok körĂ©ben, hanem arra is, hogy ez egyĂŒtt jĂĄr a hajlĂ©ktalan nĂ©pessĂ©g belsĆ ĂĄtrĂ©tegzĆdĂ©sĂ©vel, a hĂĄtrĂĄnyok tovĂĄbbi összekapcsolĂłdĂĄsĂĄval. A magyarorszĂĄgi cigĂĄnysĂĄg etnikai, iskolai, munkaerĆpiaci kirekesztettsĂ©ge immĂĄr a hazai hajlĂ©ktalansĂĄg lĂ©nyeges összetevĆjĂ©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 jelentĆsen nagyobb a (lakhatĂĄsi) krĂzisek elĆfordulĂĄsĂĄnak a kockĂĄzata Ă©s ezzel egyĂŒtt jĂĄr, hogy e csalĂĄdok körĂ©ben immĂĄr generĂĄciĂłkon keresztĂŒl öröklĆdik a hajlĂ©ktalan lĂ©thelyzet. E kĂ©t tendencia erĆsĂti is, de egyben ki is egĂ©szĂti egymĂĄst: a hazai hajlĂ©ktalansĂĄg szĂĄmottevĆ eredĆjĂ©vĂ© vĂĄlt mind a cigĂĄnysĂĄg, mind ĂĄltalĂĄban a sokgyerekes csalĂĄdok egy rĂ©szĂ©nek pauperizĂĄlĂłdĂĄsa, iskolai Ă©s munkaerĆpiaci kirekesztettsĂ©ge
âĂgy kallĂłdunk el szĂ©pen egymĂĄs utĂĄnâ. Ăllami gondozottak voltak, ma hajlĂ©ktalanok
A 2020. Ă©vi âFebruĂĄr Harmadikaâ 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. ĂltalĂĄban nem közvetlenĂŒl, hanem vĂĄltozatos nem-hajlĂ©ktalan periĂłdusokat követĆen vĂĄlnak
hajlĂ©ktalannĂĄ a volt ĂĄllami gondozottak. Az ĂĄllami gondozotti hĂĄttĂ©r â a hajlĂ©ktalan Ă©lethelyzeten belĂŒl
is â tovĂĄbbi sĂșlyos hĂĄtrĂĄnyokkal kapcsolĂłdik össze: a többiekhez kĂ©pest alacsonyabban iskolĂĄzottak,
igen magas a pszichiĂĄtriai betegek Ă©s a romĂĄk arĂĄnya a körĂŒkben, munkaerĆpiaci pozĂciĂłjuk lĂ©nyegesen
rosszabb (igen sokan kukĂĄzĂĄsbĂłl, koldulĂĄsbĂłl Ă©lnek), Ăgy jövedelmĂŒk is alacsonyabb a többiekĂ©nĂ©l. Gyakrabban
kerĂŒlnek összeĂŒtközĂ©sbe a rendfenntartĂł szervezetekkel. A korĂĄbbrĂłl hozott hĂĄtrĂĄnyok egyĂ©rtelmƱen
