Kalmia angustifolia Linnaeus, Species Plantarum 1: 391. 1753."Habitat in Pensylvania, Nova Caesarea, Noveboraco." RCN: 3084.Lectotype (Southall & Hardin in J. Elisha Mitchell Sci. Soc. 90: 18. 1974; Ebinger in Rhodora 76: 367. 1974): Herb. Linn. No. 560.2, right specimen (LINN).Current name: Kalmia angustifolia L. (Ericaceae).Note: Southall & Hardin (spring 1974) designated the material on sheet 560.2 (LINN), which comprises three specimens, as the type. However, later the same year (Sep 1974), Ebinger designated the right-hand specimen, only, as the lectotype. Ebinger’s choice is therefore treated as a restriction of the original typification made by Southall & Hardin. Annotations by Kalm on a sheet collected by him, and now in UPS, are reproduced by Lundqvist & Moberg (in Thunbergia 19: 7, f. 3. 1993).

Los Móviles del compositor cubano Harold Gramatges (Santiago de Cuba, 1918-La Habana, 2008) no han sido profundamente estudiados. Dentro de esta serie de obras, se encuentra el Móvil IV para guitarra, el cual fue escrito en 1980, pero responde a la visión estética de la vanguardia musical de la década de 1960. La presente investigación pretende responder a la pregunta: ¿cuáles fueron las técnicas y recursos composicionales utilizados por Gramatges en su Móvil IV? Para ello, se realiza un análisis general de la obra con auxilio de la partitura, el registro sonoro y algunos gráficos, especialmente diseñados para esta investigación, que muestran los recursos y procedimientos técnicos empleados por el compositor y que facilitaron la valoración holística de los múltiples elementos que conforman el discurso musical. También, se aplican conceptos y definiciones de Pierre Boulez que se adecúan a las obras pertenecientes a las vanguardias históricas.

Many lecturers involved in teacher education modules in SouthAfrica tend to follow lecturer-centred approaches when teaching the subjectcontent knowledge, which inhibits learning. Hence this study aimed toexplore how second year Intermediate Phase pre-service teachers (grades 4-6), attending an English language methodology module (PIME 303),experienced the application of the performing arts to engage with the text‘Whitney’s Kiss’ by Ohne Vegter, which is a prescribed text for theintermediate phase in South African schools. The class consisted of 40Intermediate Phase pre-service teachers, none of whom had any priorexposure to the performing arts. The research methodology was qualitative,and the design was phenomenological. Data comprised written reflectionsafter the production, which were coded and analysed thematically. Some ofthe themes emerging from the study indicate that the application ofperforming arts-based approaches within higher education classes have thepotential to develop pre-service teachers’ creativity, confidence, ability towork as a team and to reflect on how such approaches could be applied withinthe context of their own school- based learning contexts.

The compounds with ternary structures of the chalcopyrite family Cu-III-Se2 (III = Al Ga In Cr) form a wide group of semiconductor materials with diverse optical and electrical properties and the addition of FeSe binary compound produces alloys of the type (Cu-III-Se2)1-x(Fe-Se)x. These types of materials have received increasing attention as promising thermoelectric materials due to their high efficiency tunable transport properties high elemental abundance and low toxicity. This work aims to synthesize and characterize structurally a new material belonging to this semiconductor system with x = ½ the quaternary compound CuFeCrSe3. This material was prepared by the melt and anneal technique and its structure was refined from Xray powder diffraction pattern using the Rietveld method. The X-ray powder pattern was mainly composed of CuFeCrSe3 (79.1%) with CuCr2Se4 (20.9%) appearing as secondary phase. The principal phase crystallizes with tetragonal symmetry in the space group P 4 2c (Nº 112) Z = 1 with a = 5.5082(2) Å c = 10.943(1) Å V = 332.01(1) Å3. The refinement of 18 instrumental and structural parameters led to Rp = 8.8 % Rwp = 9.1 % Rexp = 7.8 % and S = 1.2. This material belonging to the semiconductor system I-II-III-VI3 crystallizes with a CuFeInSe3-type structure in a normal adamantane-structure. CuFeCrSe3 is a new semiconductor compound related to the superionic phase CuCrSe2 and can be considered as a potential candidate for mediumtemperature thermoelectric applications. --- Resumo --- Os compostos com estruturas ternárias da família da calcopirita Cu-III-Se2 (III = Al, Ga, In, Cr) formam um amplo grupo de materiais semicondutores com diversas propriedades ópticas e elétricas, e a adição do composto binário FeSe produz ligas do tipo (Cu-III-Se2)1-x (Fe-Se)x. Esses tipos de materiais têm recebido atenção crescente como promissores materiais termoelétricos devido à sua alta eficiência, propriedades de transporte sintonizáveis, alta abundância elementar e baixa toxicidade. Este trabalho buscou sintetizar e caracterizar estruturalmente um novo material pertencente a este sistema semicondutor com x = ½, o composto quaternário CuFeCrSe3. Este material foi preparado pela técnica de fusão e recozimento e sua estrutura foi refinada a partir do padrão de difração de raios-X usando o método de Rietveld. O padrão de raios X em pó foi composto principalmente de CuFeCrSe3 (79,1%) com CuCr2Se4 (20,9%) aparecendo como fase secundária. A fase principal cristaliza com a simetria tetragonal no grupo espacial P 4 2c (Nº 112), Z = 1, com a = 5.5082 (2) Å, c = 10.943 (1) Å, V = 332.01 (1) Å3. O refinamento de 18 parâmetros instrumentais e estruturais levou a Rp = 8,8%, Rwp = 9,1%, Rexp = 7,8% e S = 1,2. Este material, pertencente ao sistema semicondutor III-III-VI3, cristaliza com uma estrutura do tipo CuFeInSe3 numa estrutura normal de adamantano. O CuFeCrSe3 é um novo composto semicondutor relacionado à fase superiônica CuCrSe2, e pode ser considerado como potencial candidato a aplicações termoelétricas de média temperatura.
