Resumen

Penelitian ini memiliki tujuan untuk mendeskripsikan pembentukan karakter anak suku Ngada ( usia 6-8 tahun) melalui budaya Nalo di kampung Lodo kabupaten Ngada Nusa Tenggara Timur. Metode yang digunakan dalam penelitian ini adalah metode kualitatif enografi. Analisis data yang digunakan menggunakan analisis data Spradley. Data penelitian ini diperoleh dari hasil observasi, wawancara, dan dokumentasi. Temuan dari penelitian ini menunjukkan bahwa karakter baik atau positif anak dapat terbentuk melalui budaya Nalo. Karakter baik yang terbentuk dari budaya Nalo seperti religius, tanggung jawab, menghargai, kerja sama, dan sikap kekeluargaan yang tinggi. Ditemukan bahwa karakter tersebut terbentuk karena adanya faktor pendukung seperti niai filosofi, perspesi masyrakat, dan pembiasaan masyarakat suku Ngadha dalam melestarikan budaya Nalo. Pembentukkan karakter anak melalui budaya Nalo dilakukan di rumah dan masyarakat, dilakukan saat berkumpul makan dan minum bersama (Ka Papa Fara, Inu Papa Resi) yang selalu dilengkapi dengan minuman adat yang dikenal dengan sebutan moke.

Resumen

Introducción: en la búsqueda de nuevos materiales útiles como dosímetros termoluminiscentes (TL) la alúmina (α-Al2O3) ha adquirido gran atención. La α-Al2O3 posee una sensibilidad TL que es perceptible a las concentraciones de impurezas y a las condiciones térmicas del crecimiento de sus cristales, por lo que encontrar nuevas variaciones del material permitirá aumentar su respuesta TL. Objetivo: analizar las curvas de brillo de matrices de alúmina pura sinterizadas bajo diferentes condiciones de calcinación y dopadas con cerio a concentración 0.1 % p/p (Al2O3:Ce), usando la función asimétrica logística, para calcular sus parámetros cinéticos termoluminiscentes y explicar el comportamiento del material. Materiales y métodos: polvo de alúmina bohemita fue utilizado para preparar muestras puras sinterizadas de bajo diferentes condiciones de calcinación (NALO y ALO). El cerio se introdujo mediante impregnación húmeda utilizando nitrato de cerio hexa-hidratado. El análisis estructural de las matrices se realizó mediante Difracción de Rayos X. La lectura TL se realizó en un TLD 4500. Resultados: la deconvolución obtenida en las curvas de brillo para los grupos ALO y NALO evidencia la presencia de tres y cuatro señales TL respectivamente, y de seis señales TL en la muestra Al2O3:Ce. Conclusión: los tratamientos térmicos aplicados introdujeron un cambio sustancial en la curva de brillo del material y en su cinética TL, en términos del número de trampas y de la cantidad inicial de portadores de carga atrapados. La introducción de impurezas de cerio produjo una modificación fundamental en la curva de brillo de las matrices de alúmina.

Resumen

Este trabalho reflete sobre a reverberação na contemporaneidade do gótico em “O Barba Azul”, compilado por Charles Perrault em 1967, por meio do exame de dois contos – “The glass bottle trick” (2001), de Nalo Hopkinson, e “The last one” (2005), de Robert Coover – e dois filmes – Barbe Bleue (2009), de Catherine Breillat, e Elizabeth harvest (2018), de Sebastian Gutierrez. Investiga-se a hipótese de que, ainda que narrativas pós-modernas promovam transgressões com relação ao texto tradicional, o conflito de poder entre as personagens permanece mais ou menos inalterado. A discussão do artigo tem como suporte a noção de adaptação (HUTCHEON, 2013), interpretações mitológicas e psicanalíticas (ESTES, 1999; TATAR, 2004; CORSO e CORSO, 2006; BETTLEHEIM, 2010) e os estudos sobre reinterpretações pós-modernas de contos de fadas (BACCHILEGA, 1997, 2013).

Resumen

ABSTRACT Simultaneous overexpression of the MexAB-OprM and MexXY efflux systems was demonstrated by real-time reverse transcription-PCR and immunoblotting experiments for 12 multiresistant clinical isolates of Pseudomonas aeruginosa. DNA sequencing analysis showed that nine of these strains (named agrZ mutants) harbored mutations in mexZ, the product of which downregulates the expression of the mexXY operon. In addition, 8 of the 12 strains exhibited mutations in genes known to control transcription of the mexAB-oprM operon. Four of them were nalB mutants with alterations in the repressor gene mexR, three of them appeared to be nalC mutants deficient in gene PA3721 and overexpressing gene PA3720, and one strain was a nalB nalC double mutant. For MexAB-OprM as well as for MexXY, no clear correlation could be established between (i) the types of mutations, (ii) the expression level of mexA or mexX, and (iii) resistance to effluxed antibiotics. Finally, three isolates, named agrW mutants, overproduced MexXY and had an intact mexZ gene, and four strains overproduced MexAB-OprM and had intact mexR and PA3721 genes (nalD mutants). These data show that clinical isolates are able to broaden their drug resistance profiles by coexpressing two Mex efflux pumps and suggest the existence of additional regulators for MexAB-OprM and MexXY.

Resumen

Nalidixic acid (Nal) resistance has been used as a selective marker for studies of pathogen-inoculated fruits and vegetables. A collection of 24 Salmonella isolates were screened for natural resistance to Nal (50 μg/ml). The resistance to ionizing radiation was determined and compared for i) three naturally Nal-resistant (NalR) strains, ii) three naturally Nal-sensitive (NalS) strains, and iii) three strains derived from NalS strains that were made resistant to Nal (NalRi) by successive culturing and selection in Nal-amended broth. The radiation D10-values (the radiation dose required to achieve a 1-log reduction in population) were determined in buffer solution and in orange juice. D10-values were significantly (P < 0.05) different among the Salmonella isolates tested. When considered as a group, NalR isolates were significantly more sensitive to ionizing radiation than NalS isolates in both media tested. In buffer, D10 of NalR was 0.210 kGy versus 0.257 kGy for NalS. In orange juice, D10 of NalR was 0.581 versus 0.764 for NalS. Inducing resistance to Nal altered the response to irradiation. D10-value of NalRi was 0.234 kGy in buffer, a 9% reduction relative to NalS parents. In orange juice, the D10-value of NalRi was 0.637 kGy, a reduction of 17% relative to NalS parents. These results suggest that natural and/or induced resistance to Nal may predispose Salmonella isolates to greater sensitivity to ionizing radiation, and that this effect is influenced by the suspending medium and by the nature of the isolates evaluated.

Resumen

ABSTRACT Mutations in genes mexR and nalC have previously been shown to drive overexpression of the MexAB-OprM multidrug efflux system in Pseudomonas aeruginosa. A transposon insertion multidrug-resistant mutant of P. aeruginosa overproducing MexAB-OprM was disrupted in yet a third gene, PA3574, encoding a probable repressor of the TetR/AcrR family that we have dubbed NalD. Clinical strains overexpressing MexAB-OprM but lacking mutations in mexR or nalC were also shown to carry mutations in nalD. Moreover, the cloned nalD gene reduced the multidrug resistance and MexAB-OprM expression of the transposon mutant and clinical isolates, highlighting the significance of the nalD mutations vis-à-vis MexAB-OprM overexpression in these isolates.

AbstractNew organotin (IV) complexes with NaL1 (sodium salt of 2-[[4-(3-methoxy-propoxy) 3-methylpyridin-2-yl]methylsulfinyl]benzimidazol-1-ide) and NaL2 (sodium salt of 3- aminomethyl-5-methylhexanoic acid) were synthesized by the reaction of diorganotin (IV) and triorganotin (IV) salt (Bu3SnCl, Ph3SnCl, Bu2SnCl2, Me2SnCl2) using the solvent (dry toluene) by constant stirring and refluxing. All the organotin (IV) complexes were characterized by different diagnostic techniques such as FT-IR (Infra-red) and UV-visible spectroscopy. The results exhibited that ligand NaL1 (sodium salt) is attached to tin metal by a nitrogen atom of benzimidazole ring and the oxygen atom of the sulfonyl group. While ligand NaL2 (sodium salt) coordinate with tin(IV) moiety through oxygen atom of the carboxylate group. The newly synthesized complexes 1 & 2 of ligand NaL1 (sodium salt) showed trigonal bipyramidal geometry while complexes 3 & 4 octahedral geometry around tin(IV) centre. The organotin(IV) complexes 5-7 of ligand NaL2 (sodium salt) have the tetrahedral geometry around tin(IV) centre. The synthesized complexes (1-7) were tested for antifungal and antibacterial microbial activities. All the complexes showed significant antibacterial and anti-fungal activities against tested bacterial and fungal strains.

Resumen

An inquiry into onto-epistemology, this essay investigates the reciprocal production of aesthesis and empiricism, both the seemingly scientific and the perceptual knowledge that signifies otherwise under conditions of imperial Western humanism. In a reading of Nalo Hopkinson’s Brown Girl in the Ring (1998), I argue that as an enabling condition of imperial Western humanism, the black mater(nal) is foreclosed by the dialectics of hegemonic common sense and that the anxieties stimulated by related signifiers, such as the black(ened) maternal image, voice, and lifeworld, allude to the latent symbolic-material capacities of the black mater(nal), as mater, as matter, to destabilize or even rupture the reigning order of representation that grounds the thought-world relation. In other words, the specter of the black mater(nal)—that is, nonrepresentability—haunts the terms and operations tasked with adjudicating the thought-world correlate or the proper perception of “the world” such as hierarchical distinctions between reality and illusion, Reason and its absence, subject and object, science and fiction, and speculation and realism, which turn on attendant aporias pertaining to immanence and transcendence. Exploring the mind-body-social nexus in Hopkinson’s fiction, I contend that in Brown Girl vertigo is evoked as both a symptom and a metaphor of inhabiting a reality discredited (a blackened reality) that is at once the experience of the carceral and the apprehension of a radically redistributed sensorium. I argue the black mater(nal) holds the potential to transform the terms of reality and feeling, therefore rewriting the conditions of possibility of the empirical.

Resumen

ABSTRACT Several nalB-type multidrug-resistant mutants ofPseudomonas aeruginosa overexpressed MexAB-OprM and carried mutations in the local regulatory gene, mexR. Others, dubbed nalC types, carried mutations elsewhere and overexpressed MexAB-OprM less extensively than the nalBstrains. Available evidence showed that MexR acted solely as repressor. Disruption of the mexR gene at various places suggested that the 5′ end of mexR may be a part of themexAB-oprM promoter.

Resumen

ABSTRACT Carbapenems are important agents for the therapy of infections due to multidrug-resistant Pseudomonas aeruginosa; the development of carbapenem resistance hampers effective therapeutic options. To assess the mechanisms leading to resistance, 33 clinical isolates with differing degrees of carbapenem susceptibility were analyzed for the expression of the chromosomal β-lactamase (ampC), the porin that is important for the entry of carbapenems (oprD), and the proteins involved in four efflux systems (mexA, mexC, mexE, and mexX). Real-time reverse transcriptase PCR was performed using primers and fluorescent probes for each of the target genes. The sequencing of regulatory genes (ampR, mexR, nalC, nalD, mexT, and mexZ) was also performed. Diminished expression of oprD was present in all imipenem- and meropenem-resistant isolates but was not required for ertapenem resistance. Increased expression of ampC was not observed in several isolates that were overtly resistant to carbapenems. Increased expression of several efflux systems was observed in many of the carbapenem-resistant isolates. Increased efflux activity correlated with high-level ertapenem resistance and reduced susceptibility to meropenem and aztreonam. Most isolates with increased expression of mexA had mutations affecting nalC and/or nalD. Two isolates with mutations leading to a premature stop codon in mexZ had markedly elevated mexX expressions, although mutations in mexZ were not a prerequisite for overexpression. β-Lactam resistance in clinical isolates of P. aeruginosa is a result of the interplay between diminished production of oprD, increased activity of ampC, and several efflux systems.

Abstract Seventeen analogs of the luteinizing hormone releasing hormone (LHRH) have been synthesized, bioassayed, and compared for antiovulatory activity (AOA) in rats. The emphasis of design was replacement of Tyr5 of LHRH. Position 5 has not been extensively studied. [N-Ac-D-2-Nal1 , D-pClPhe2 , D-3-Pal3 , D-Arg6 , D-Ala10 ]-LHRH was the baseline for new designs. Comparison of the AOA's of the 17 analogs with the baseline revealed the two peptides with Phe5 and 3-Pal5 had equivalent AOA's, and were the best of the 17, and about 45% more potent than the baseline. Analogs with pClPhe5 , oClPhe5 , α-MepClPhe5 , 2-Nal5 , Trp5 , and His5 were less potent than the Phe5 -and 3-Pal5 -analogs. Based on the Phe5 -analog, eight other analogs were synthesized with changes in positions 1, 2, 3 and 7 and although none were better than the baseline, 5/8 showed 20-60% AOA's at 250 ng and revealed optimum positions for new designs.

Resumen

AbstractThe breed differences in post-parturient rise (PPR) in faecal egg counts in lambing ewes of different breeds naturally infected with Haemonchus contortus were compared. The ewes of Nali, 50% Nali × 50% Russian Merino/Corriedale and 37.5% Nali × 62.5% Russian Merino/Corriedale were treated with fenben-dazole while ewes of the above three breeds as well as 25% Nali × 75% Russian Merino/Corriedale, were kept untreated. Observations from 3 weeks before lambing to 12 weeks post-lambing at weekly intervals revealed that in treated ewes, egg counts of Nali did not differ significantly with 50% Nali whereas 37.5% Nali had significantly higher egg counts than those of Nali and 50% Nali. In untreated ewes egg counts of 50% Nali were significantly higher than that of Nali on some occasions, while 25% Nali had significantly higher egg counts than the other three breeds. None of the ewes from the Nali breed showed signs of haemonchosis, whereas few lambing ewes of the three Nali crosses (50%, 37.5% and 25% Nali) showed signs of haemonchosis and one ewe of the latter breed died.

Resumen

This article deals with the impact of a major redesign of public space at a cross-border market on the Russian—Chinese border on customer—seller interrelations. The location in question is the Chinese border town of Manzhouli, which, over the last two decades, has risen to become a bustling town of cross-border tourism and retail trade. It will be shown that the large-scale replacement of makeshift market stalls by huge, ostentatious department store buildings is paralleled by the way Chinese traders try to impose a more restricted and rule-governed price regime in their interactions with Russian customers. Russian customers react to this recent shift in appearance and behaviour by sticking to received perceptions of the border as a place outside orderly society and will accordingly reject the Chinese reinterpretation of the cross-border market location.

Resumen

A wet de-NOxtechnique based on an UV-enhanced NaClO oxidation process was investigated for simulated flue gas of a diesel engine using a bench-scale reaction chamber. The effects of UV irradiation time, initial pH value, and available chlorine concentration of NaClO solution were studied, respectively. The results showed that when the UV irradiation time was 17.5 min and the initial pH value of NaClO solution was 6, NO removal efficiency of UV/NaClO solution was increased by 19.6% compared with that of NaClO solution. Meanwhile, when the available chlorine concentration of NaClO solution decreased from 0.1 wt% to 0.05 wt%, the enhancement in NO removal efficiency of UV/NaClO solution increased from 19.6% to 24%, compared with that of NaClO solution. The reaction pathways of NaClO solution photolysis and NO removal by UV/NaClO process were preliminarily discussed. The results suggested that HOCl might be the most active species that released many UV-induced photooxidants through photolysis reactions, which played an important role in NO removal process.

Resumen

Solid phase technique on p-methylbenzhydrylamine resin was used for the synthesis of four analogs of oxytocin and four analogs of vasopressin with the non-coded amino acids L- or D- and 1- or 2-naphthylalanine and D-homoarginine. [L-1-Nal2]oxytocin, [D-1-Nal2]oxytocin, [L-2-Nal2]oxytocin, [D-2-Nal2]oxytocin, [L-1-Nal2, D-Har8]vasopressin, [D-1-Nal2, D-Har8]vasopressin, [L-2-Nal2, D-Har8]vasopressin and [D-2-Nal2, D-Har8]vasopressin were synthesized. All eight analogs were found to be uterotonic inhibitors in vitro and in vivo. Analogs with 2-naphthylalanine are stronger inhibitors, particularly in the vasopressin series than the analogs with 1-naphthylalanine. Analogs with 1-naphthylalanine have no activity in the pressor test, analogs with 2-naphthylalanine are weak pressor inhibitors.

Resumen

Abstract The problems related to the determination of the absolute molecular weight (Mw) of sodium lignosulfonate (NaLS) are the focus of the present work. Four narrow-dispersed NaLS fractions were collected by filtration, ultrafiltration, and gel permeation chromatography (GPC), and their Mw measured by laser light scattering (LLSMw) was compared with that obtained by GPC (GPCMw). The LLSMw values were much larger than GPCMw, and this Mw difference increased with increasing Mw of NaLS. This finding confirms the known polyelectrolyte and aggregation effects of NaLS. The deviation is also partly due to the conformation differences between the GPC standard (sodium polystyrene sulfonate) and the NaLS molecules. The effects of polyelectrolytes and NaLS aggregates could be inhibited by adding enough NaCl salt in the NaLS solution and filtering the NaLS/NaCl solution through a syringe filter. As a result, the slow mode in dynamic LLS measurement disappeared. By this approach, the absolute LLSMw values were only slightly larger than that determined by GPC due to the conformation differences between the GPC standard and the NaLS molecules.

Resumen

The temperature dependence of the dynamics of sodium lignosulfonate (NaLS) solution with high salt concentration was investigated by static and dynamic light scattering. The results showed that there existed fast mode and slow mode in NaLS aqueous solution. After enough addition of salt (1.2 M NaCl), slow mode in NaLS solution disappeared when NaLS molecules became electric neutrally. On this basis, the NaLS molecules aggregated and leaded to the re-formation of slow mode if the temperature of NaLS solution was above 311.15K. There was no splitting phenomenon in correlation function and size distribution when slow mode appeared under room temperature in NaLS solution. The correlation function would split into two stages when the size difference between fast and slow modes exceeded certain limit.

Resumen

Na2O excess 95(Na0.5K0.5)NbO3-5LiTaO3 (NKN-5LT) ceramics were developed by conventional sintering process. Sintering temperature was lowered by adding Na2O as a sintering aid. Grain growth behaviors with Na2O addition were explained in terms of the effect of Na2O on interface reaction - controlled grain growth and the critical driving force. The electrical properties of NKN-5LT ceramics were investigated as a function of Na2O concentration. In the 1 mol% Na2O excess NKN-5LT samples sintered at 1000oC for 4h in air, electromechanical coupling factor (kP) and piezoelectric coefficient (d33) of NKN-5LT ceramics were found to reach the highest values of 0.43 and 190 pC/N, respectively.
