Ksavers Andermanis – LU Akadēmiskās nozīmītes meta autors
No full textRaksts tapis kā turpinājums 2024. gada septembra mēneša priekšmetam par Latvijas Universitātes (LU) Akadēmisko nozīmīti, kur uzmanība pievērsta LU Akadēmiskās nozīmītes meta autoram, LU Arhitektūras fakultātes studentam un novadpētniekam, vācbaltietim Ksaveram Andermanim. K. Andermanis ne tikai ir sniedzis ieguldījumu Latvijas etnogrāfijas pētniecībā, bet arī LU simbolu izgatavošanā, kas mūsdienās saglabā savu unikalitāti un vērtību. Meta autora piederība pie LU saimes sakņojusies jau viņa ģimenē, jo viņa tēvs ir absolvējis Rīgas Politehnisko institūtu, LU priekšteci starpkaru periodā, un strādājis LU Saimniecības padomē par inspektoru.The article is a continuation of the September 2024 Museum Object on the Academic Badge of the University of Latvia (UL), which focuses on the author of the UL Academic Badge design, the student of the Faculty of Architecture and local historian, the Baltic German Ksavers Andermanis. K. Andermanis has not only contributed to the research of Latvian ethnography, but also to the production of symbols of the UL, which today retain their uniqueness and value. The author's belonging to the UL family is rooted in his family, as his father graduated from the Riga Polytechnic Institute, the predecessor of UL during the interwar period, and worked as an inspector at the UL Economical council
Zastosowanie pirolitycznej metylacji w oznaczaniu profi lu krótkołańcuchowych kwasów tłuszczowych w wybranych preparatach farmaceutycznych techniką GC/MS
No full textLactic Acid Bacteria (LAB) belong to the normal fl ora of human alimentary tract and vaginal epithelium. The main products of LAB metabolism are short chain fatty acids (SCFA), which are known to have signifi cant infl uence on human health. The aim of this study was to examine the suitability of direct pyrolytic methylation in GC/MS profi ling of SCFA in the selected pharmaceutical preparations of LAB. For method optimization, standard SCFA samples consisting of acetic, propionic, butyric and lactic acids were pyrolyzed under various temperature conditions in the presence of methanolic solution of tetramethylammonium hydroxide (TMAH) as a derivatizing reagent. It was demonstrated that pyrolytic derivatization of standard SCFA to methyl esters was the most effi cient with the use 10% TMAH and the pyrolytic fi laments with Curie temperature of 480°C, when the pyrolysis cell was kept at 150°C. It was shown that the method is suitable for GC/MS qualitative analysis of SCFA profi le in the pharmaceutical preparations that contain LAB in lyophilized form.Bakterie kwasu mlekowego (Lactic Acid Bacteria – LAB) należą do naturalnej flory bakteryjnej zasiedlającej przewód pokarmowy oraz nabłonek pochwy człowieka. Głównym produktem metabolizmu LAB są krótkołańcuchowe kwasy tłuszczowe (short-chain fatty acids – SCFA) wywierające istotny wpływ na zdrowie człowieka. W pracy poddano ocenie przydatność techniki bezpośredniej metylacji pirolitycznej w oznaczaniu profi lu SCFA w wybranych preparatach farmaceutycznych LAB techniką GC/MS. W celu optymalizacji metody, wzorcowe próbki SCFA zawierające kwas octowy, propionowy, masłowy i mlekowy poddano pirolizie w obecności metanolowego roztworu wodorotlenku tetrametyloamoniowego (TMAH) w różnych warunkach temperaturowych. Stwierdzono, że derywatyzacja analizowanych kwasów tłuszczowych do estrów metylowych zachodziła z największą wydajnością pod wpływem 10% TMAH, gdy zastosowano druty pirolityczne o temperaturze Curie 480°C, a komorę pirolizera utrzymywano w temperaturze 150°C. Wykazano, że zoptymalizowana metoda jest przydatna w prowadzonej techniką GC/MS analizie jakościowej profi lu SCFA w wybranych preparatach farmaceutycznych zawierających LAB w formie liofi lizatu
Lu Xun's Revolution : Writing in a Time of Violence /
No full textRecognized as modern China’s preeminent man of letters, Lu Xun (1881–1936) is revered as the nation’s conscience, a writer comparable to Shakespeare or Tolstoy. Gloria Davies’s vivid portrait gives readers a better sense of this influential author by situating the man Mao Zedong hailed as "the sage of modern China" in his turbulent time and place.Widely recognized as modern China’s preeminent man of letters, Lu Xun (1881–1936) is revered as the voice of a nation’s conscience, a writer comparable to Shakespeare and Tolstoy in stature and influence. Gloria Davies’s portrait now gives readers a better sense of this influential author by situating the man Mao Zedong hailed as "the sage of modern China" in his turbulent time and place. In Davies’s vivid rendering, we encounter a writer passionately engaged with the heady arguments and intrigues of a country on the eve of revolution. She traces political tensions in Lu Xun’s works which reflect the larger conflict in modern Chinese thought between egalitarian and authoritarian impulses. During the last phase of Lu Xun’s career, the so-called "years on the left," we see how fiercely he defended a literature in which the people would speak for themselves, and we come to understand why Lu Xun continues to inspire the debates shaping China today. Although Lu Xun was never a Communist, his legacy was fully enlisted to support the Party in the decades following his death. Far from the apologist of political violence portrayed by Maoist interpreters, however, Lu Xun emerges here as an energetic opponent of despotism, a humanist for whom empathy, not ideological zeal, was the key to achieving revolutionary ends. Limned with precision and insight, Lu Xun’s Revolution is a major contribution to the ongoing reappraisal of this foundational figure.Recognized as modern China’s preeminent man of letters, Lu Xun (1881–1936) is revered as the nation’s conscience, a writer comparable to Shakespeare or Tolstoy.

Lu Xun zaoqi wenyan lunwen li suo tansuo de xin wenhua (The 'New Culture' formulated in Lu Xun's early classical-style essays)
No full textThis article links a number of the main themes expressed in Lu Xun's early wenyan essays, written in Japan in 1906-1908, with the concerns of the New Culture Movement, which emerged later (circa 1919) in China. The author argues that these book-length theses written in dense classical language were in fact intellectual precursors to the New Culture Movement and its aftermath. It delineates a partial outcome of the author's Australian Research Council (ARC) project on the early Lu Xun and his formative period in Japan
Mobile Exam System – MES: Architecture for Database Management
No full textAs the mobile applications are constantly facing a rapid development in the recent years especially in the academic environment such as student response system (Lópeza, Royoa, Labordab & Calvoa, 2009; Ngai & Gunasekaran, 2007; Mary & Biju, 2008; Nayak & Erinjeri, 2008; Roth, Ivanchenko & Record, 2008; Lu, Stav & Pain, 2009; Lu, 2009; Turning technologies, 2010) used in universities and other educational institutions; there has not been reported an effective and scalable Database Management System to support fast and reliable data storage and retrieval. This paper presents Database Management Architecture for an Innovative Evaluation System based on Mobile Learning Applications. The need for a relatively stable, independent and extensible data model for faster data storage and retrieval is analyzed and investigated. It concludes by emphasizing further investigation for high throughput so as to support multimedia data such as video clips, images and documents

An LU-gradient formulation for the eigenvalue moment method, 1995
No full textThe Eigenvalue Moment Method (EMM) has proven to be an effective technique for generating converging lower and upper bounds to the bosonic ground state energy of singular, strongly coupled, quantum systems. An alternate gradient method formulation for the EMM as previously developed by Dr. Carlos Handy is presented. The present method is numerically faster and is based on an LU decomposition formulation for the underlying Hankel-Hadamard moment matrices. The LU-EMM gradient formulation deals with a sequence of functions, each convex over a corresponding subset. The LU-EMM gradient method is applied to the octic, sextic and quartic anharmonic oscillator potentials in one dimension
