Koncepciós perek Kárpátalján a második világháború után
No full textA második világháború után az Elbától keletre, Európa számos országában bírósági
eljárások sorozata vette kezdetét, amelyek keretében koncepciós perbe fogták
azon személyeket, akik az új rend vélt, vagy valós ellenzőinek számítottak a
kommunista vezetés szemében. Hasonló folyamat kezdődött a Szovjetunióhoz
csatolt Kárpátalján is. A tisztogatást a szovjet birodalomban a már több éve alkalmazott
gyakorlat alapján végezték: koncepciós pereket kreáltak a rendszer
számára nemkívánatos személyek ellen. Ennek értelmében a kárpátaljai közösséggel
szemben is alkalmazott szovjet igazságszolgáltatás a szó betű szerinti értelmében
a politika „szolgálólányává” vált.
A perbe fogott elsődleges célcsoport a kárpátaljai értelmiség volt: mindazon
személyek, akik a hatalomváltás előtt valamilyen hivatali funkciót töltöttek be,
illetve a történelmi egyházak képviselői. Koholt vádak – hazaárulás, kémkedés,
szovjetellenes összeesküvés, lázadás és politikai banditizmus, hazaárulók családtagjai,
társadalmilag veszélyes elem stb. – alapján országgyűlési képviselők,
ügyvédek, papok, tanítók, hivatalnokok jelentős részét ítélték el sokéves börtönre
vagy golyó általi halálra, megtizedelve a kárpátaljai magyarság színe-javát.1
Ezt elősegítették azok a nyilvántartások, amiket az 1940–1944 között működő
hivatalnokok tevékenységéről vezettek.2 A koncepciós perek révén a vezetők
nélkül maradt, megfélemlített kárpátaljai közösséget a hatalom képviselői sokkal
inkább akadálymentesen tudták beintegrálni a szovjet rendszerbe
Extraction of metallic values from Küre massive rich copper ore by pressure leaching
No full textBu çalışmada, Küre masif zengin bakır cevherinin basınç altında liçi çalışılmıştır. Deneylerde süre, sıcaklık, oksijen kısmi basıncı, katı konsantrasyonu, asit konsantrasyonu ve katalizör olarak gümüş iyonları ilavesinin metal çözünme verimleri üzerindeki etkileri araştırılmıştır. Optimum çözündürme koşulları 160°C sıcaklık, 0.4 M başlangıç H2SO4 konsantrasyonu, 20 bar oksijen kismi basıncı, 50 g/l katı konsantrasyonu ve 120 dak liç süresi olarak belirlenmiştir. Bu koşullarda bakır %95, kobalt %70 ve çinko %97 verimle çözeltiye alınabilmiştir. Ortama az miktarda gümüş iyonları ilavesinin liç prosesini hızlandırıcı etkisi olduğu belirlenmiştir. Bakır çözünme kinetiği incelenmiş ve çözünme reaksiyonunun aktivasyon enerjisi 52,74 kJ/mol olarak bulunmuştur. Bu değer reaksiyonun difüzyon kontrollü olduğunu göstermektedir.Anahtar Kelimeler: Kalkopirit, bakır cevheri, basınçlı liç.Several hydrometallurgical treatments such as chloride, sulfate, nitrate, and amine based processes are used for leaching of chalcopyrite, sphalerite, and galena concentrates as alternative to pyrometallurgical processes. Sulfate-based hydrometallurgical processes are usually employed as ferric sulfate leaching, oxygen pressure leaching, or bacterial leaching. The aim of this study was to investigate the possibilities of recovering metallic values from Küre massive rich copper ore by pressure leaching. Massive rich copper ore, taken from Küre and containing 7.43 % Cu, 0.044 % Pb, 0.33 % Zn, 0.08 % Co, 0.002 % Ni, 1 (g/t) Au, 14 (g/t) Ag, was subjected to this experimental study. In the leaching tests, the effects of leaching time, temperature, partial oxygen pressure, solids concentration, initial acid concentration, and silver ion addition as a catalyst on metal leaching recoveries were investigated and optimum leaching conditions were determined. The optimum leaching conditions were found as 160°C temperature, 0.4 M initial H2SO4 concentration, 20 bar partial oxygen pressure, 50 g/l solids concentration, and 120 min leaching time. Approximately 95% of copper, 70% of cobalt and 97% of zinc were extracted under these conditions. It was also shown that silver ions could be added in small quantities for enhancing the leach process. Copper leaching kinetics was also studied and an activation energy for copper dissolution reaction was found as 52,74 kJ/mol which shows diffusion controlled process.Keywords: Chalcopyrite, copper ore, pressure leaching
The philosophical nature of maimonides’ thirteen principles of faith
No full textMusa b. Meymûn (ö. 1204) Perek Helek Şerh’nde Yahudiliğin on üç inanç ilkesini açıklamıştır. Bu ilkeleri kurtuluşa erişmek ve Yahudi kimliğine sahip olmak için zorunlu kriterler olarak sunmuştur. On üç ilke zaman içerisinde geleneksel Yahudiliğin temelleri olarak kabul edilmiştir. Öte taravan İbn Meymûn on üç ilkeyi Sefer ha-Mada isimli başka bir kitabında da aynı içerikle tekrar dile getirmiştir. Fakat Sefer ha-Mada Yahudi âlimler tarafından geleneksel Yahudiliğe aykırı felsefi içeriğe sahip olmakla suçlanmış ve yasaklanmıştır. Dolayısıyla İbn Meymûn inanç ilkelerini her iki eserinde de aynı içerikle inşa etmesine rağmen biri geleneksel Yahudiliğin temelleri olarak kabul edilmiş, diğeri ise geleneksel Yahudiliğe yabancı olmakla suçlanmıştır. Bu makalede, Sefer ha-Mada’nın yasaklanmasına neden olan felsefi içeriğin Perek Helek Şerh’ndeki on üç ilkede de bulunduğu gösterilmeye çalışılmıştır. Ayrıca felsefi içeriğine rağmen on üç ilkenin Yahudi toplumu tarafından benimsenmesinin nedeni araştırılmıştırMaimonides (d. 1204) explained the thirteen faith principles of Judaism in his Commentary on Perek Helek. He presented these principles as mandatory criteria for attaining salvation and having a Jewish identity. Over time, the thirteen principles were accepted as the foundations of traditional Judaism. On the other hand, Maimonides reiterated the thirteen principles with the same content in another book called Sefer ha-Mada. However, Sefer ha-Mada was accused by Jewish scholars of having philosophical content contrary to traditional Judaism and was banned. erefore, although Maimonides constructed the principles of faith with the same content in both works, one was accepted as the foundations of traditional Judaism, while the other was accused of being alien to traditional Judaism. is article attempts to show that the philosophical content that led to the prohibition of Sefer ha-Mada is also found in the thirteen principles in the Commentary on Perek Helek. It also explores why the thirteen principles have been embraced by the Jewish community despite their philosophical content
Transcatheter aortic valve replacement in the management of aortic insufficiency secondary to left ventricular assist device implantation: a case report
No full textbackground: left ventricular assist device (LVAD) is considered either a destination therapy for patients with end-stage heart failure or heart transplantation bridging. LVAD implantation often causes aortic insufficiency (AI), which requires aortic valve repair. however, severe acute aI does not respond well to medication, and re-operation means higher risk to the patients; the most effective therapeutic strategies for LVAD-induced AI still need further exploration. In this report, we present the first described case of new-onset, severe LVAD-induced aI in china with a patient who underwent transcatheter aortic valve replacement (TAVR) and achieved significant improvement in functional capacity and symptoms with lower operation risk. case description: a 55-year-old male patient was diagnosed with dilated cardiomyopathy for 14 years. The effect of the medication gradually deteriorated, LVAD (HeartCon®) was implanted one year earlier. the patient complained of intermittent chest tightness for one week, which had been aggravated for two days before hospitalization. echocardiographic findings revealed new-onset, severe LVAD-induced AI. TAVR was performed with a self-expandable stent-valve (TAV30, vitaflow Liberty). within minutes, the patient recovered with rapid disappearance of chest tightness and stable vital signs. before discharge, the position of the artificial valve was fixed without incomplete closure nor thrombus attachment, yielding a left ventricular ejection fraction (LVEF) of 35%. the patient was hospitalized for 38 days, and followed up with outpatient treatment, the condition was stable until 19 June 2023. conclusions: TAVR could be an effective, safe, and less invasive means of restoring ejection fraction for patients with a LVAD who develop severe AI

Effect Of Severe Plastic Deformation On Microstructure Evolution Of Pure Aluminium
No full textProcesses of severe plastic deformation (SPD) are defined as a group of metalworking techniques in which a very large plastic strain is imposed on a bulk material in order to make an ultra-fine grained metal. The present study attempts to apply Equal-Channel Angular Pressing (ECAP), Hydrostatic Extrusion (HE) and combination of ECAP and HE to 99.5% pure aluminium. ECAP process was realized at room temperature for 16 passes through route Bc using a die having an angle of 90°. Hydrostatic extrusion process was performed with cumulative strain of 2.68 to attain finally wire diameter of d = 3 mm. The microstructure of the samples was investigated by means of transmission and scanning electron microscopy. Additionally, the microhardness was measured and statistical analysis of the grains and subgrains was performed. Based on Kikuchi diffraction patterns misorientation was determined. The measured grain/subgrain size show, that regardless the mode of deformation process (ECAP, HE or combination of ECAP and HE processes), grain size is maintained at a similar level – equal to d = 0.55-0.59 μm. A combination of ECAP and HE has achieved better properties than either single process and show to be a promising procedure for manufacturing bulk UFG aluminium
