Copper phthalocyanine (CuPc) blue, commonly named phthalo blue is the most important synthetic organic blue pigment in the 20th and 21st century artists paints. Phthalo blue, which is adopted by artists since 1936, is a polymorphous pigment. Currently, the alpha, beta and epsilon CuPc polymorphs are used in artists paint formulations. The identification of the CuPc crystal form provides technical and chronological information relevant for studying artworks. Raman Spectroscopy (RS) is a very valuable technique for the detection of phthalo blue in paint layers. However, the spectral interpretation is not straightforward concerning the CuPc polymorph distinction. To overcome the problem we have previously developed a procedure combining RS and chemometrical analysis. The experimental results that we obtained have demonstrated its efficiency for predicting the CuPc crystal form in unknown paint samples. In the present work, this procedure was applied on oil-based and acrylic paints from Sam Francis’ studio and the Getty Conservation Institute (GCI) Reference Collection. [less ▲]

In the four jurisdictions, labour law has granted a different status to workers said to be "white collar" and others said to be "blue collar workers". Therefore labour law had to formulate a criterion precise enough to put each particular case in one of these two categories. This required desperate efforts because the distinction is grounded partly in real situations but also on biases which distort the perception of reality. By studying the way in which lawyers have reasoned, one can compare various ways of approaching a same problem and note the unease of these lawyers and their approach stripped of what the peculiar features through which these phenomena manifest themselves in each country may accidentally present. - Le droit du travail de ces quatre pays a donné des statuts juridiques différents aux travailleurs dits ouvriers et aux travailleurs dits employés. Il a donc dû élaborer un critère assez précis pour pouvoir ranger chaque cas individuel dans une de ces deux catégories. Effort presque désespéré parce que la distinction repose non seulement sur la différence des situations réelles, mais aussi sur des préjugés qui ont faussé la perception de la réalité. L'étude de la façon dont on a raisonné permet de comparer diverses manières d'aborder un même problème et d'apercevoir l'embarras et les méthodes des juristes dépouillés de ce que les traits particuliers par lesquels ils se manifestent dans chaque pays peuvent comporter d'accidentel.

The inhibition of cholesterol synthesis by a statin enhances intestinal absorption of both cholesterol and various phytosterols. The atherogenic role of phytosterols, well proven in hypersitosterolemia, is now suspected in patients with premature coronary artery disease. The cholestanol/cholesterol ratio can be used as a marker of intestinal cholesterol absorption. Individuals with elevated ratio ("high absorbers") have less favourable cholesterol-lowering response and cardiovascular protection with statin therapy as compared to individuals with low ratio ("high synthesizers"). They may benefit of an adjunct therapy with phytostanols or ezetimibe, both being capable to reduce plasma concentrations of cholesterol and of phytosterols. [less ▲]

The present study focuses on the branchial basket in four Carapidae species: Carapus acus , Encheliophis boraborensis , Encheliophis homei and Encheliophis gracilis . The aim is to highlight the skeletal and muscular features of the branchial basket, especially those that are believed to be related to their way of life and/or to be linked to the presence of primary sound-producing muscles. The space occupied by the primary sound-producing muscles between the neurocranium and the branchial basket gives rise to distinctive skeletal and muscular features. They prevent the 1st pharyngobranchials from becoming attached to the neurocranium in the normal way. These do not seem to play any role in the suspension of the upper pharyngeal jaws, as it is usually the case in teleosteans. The 1st epibranchials are separated from the 2nd pharyngobranchials. Ossified interarcual elements jointed to the 2nd pharyngobranchials and 1st epibranchials are found in the position usually occupied by the latter. The presence of primary sound-producing muscles gives rise to the need for the reorganisation of the musculature which is seen in particular with regards to the levatores branchiales. These are not found on the neurocranium but on the hyomandibular. The general skeletal and muscular data and the observations of the stomach contents suggest that the action of the branchial basket is restricted to carrying food in Carapus acus , Encheliophis boraborensis and Encheliophis homei , whereas it could also play a role in the work of cutting up soft food in Encheliophis gracilis .

This paper describes a rare occurrence of a rich and diverse palynological assemblage from a controversial stratigraphic unit in well EW8 in northwestern Saudi Arabia. The composition of this assemblage strongly suggests a Pridoli age and therefore it is referred here to the Tawil Formation. The assemblage encountered contains very characteristic chitinozoans, acritarchs, tasmanities, scolecodontsm, eurypterid cuticle and common land-derived miospores and hilate cryptospores. Chitinozoans such as Margachitina elegans, Ancyrochitina fragilis brevis, Ancyrochitina fragilis, Sphaerochitina sphaerocephala, Urnochitina urna, Pseudochlathrochitina carmenchui and Lagenochitina brevicollis confer the Pridoli age assignment. This assemblage of chitinozoans correlates very well with Assemblage D from the Alternances Gréso-Argileuses Formation of the A1-61 well in northwestern Libya. Among the acritarchs present are: Cymbosphaeridium pilar, Leoniella carminae,Diexallophasis spp., Tunisphaeridium cf caudatum, Leiofusa estrecha and Eupoikilofusa striatifera. <br /> <br />Furthermore, the join occurrence of U. urna, P. carmenchui and M. elegans is clearly indicative of the middle part of the Pridoli as in the Libyan well A1-61, and in many wells in Algeria. This corresponds to what is considered to be a transgressive mid Pridoli event in the Algerian Sahara, with non marine intervals bracketing this brief marine sea level rise. This event is likely to have extended into all of north Gondwana including Arabia. [less ▲]

In this paper, we prove that if U is an increasing sequence of strictly positive and continuous functions on a locally compact Hausdorff space X such that VBAR congruent-to VBAR and C(X), then the Frechet space CU(X) is distinguished if and only if it satisfies Heinrich's density condition, or equivalently, if and only if the sequence U satisfies condition (H) (cf. e.g.`[1] for the introduction of (H)). As a consequence, the bidual lambda(infinity)(A) of the distinguished Kothe echelon space lambda-0(A) is distinguished if and only if the space lambda-1(A) is distinguished. This gives counterexamples to a problem of Grothendieck in the context of Kothe echelon spaces. [less ▲]

The precise location of transcribing rRNA genes within Ehrlich tumor cell nucleoli has been investigated using two approaches: high-resolution autoradiography of cells pulse-labelled with tritiated uridine, varying the exposure time, and in situ-in vitro transcription coupled with an immunogold labelling procedure. When autoradiographic preparations are exposed for a short time, silver grains are found associated almost exclusively with interphasic cell nucleoli. Labelling of extranucleolar areas requires longer exposure. Within the nucleolus, the first sites to be revealed are in the dense fibrillar component. Prolonging exposure increases labelling over the dense fibrillar component, with label becoming more and more apparent over the fibrillar centers. Under these conditions, however, labelling does not extend into the granular component, and no background is observed. Initiation of transcription on ultrathin cell sections occurs preferentially at the borders of condensed chromatin blocks and in their close vicinity. The condensed chromatin areas themselves remain unlabelled. Inside most nucleoli, gold-particle clusters are mainly detected in the fibrillar centers, especially at their periphery, whereas the dense fibrillar component and the granular component remain devoid of label. These results, together with previous observations made on the same cell type, clearly indicate that the fibrillar centers are the sites of rRNA gene transcription in Ehrlich tumor cell nucleoli, while the dense fibrillar component is the site of pre-rRNA accumulation.

Cánepa2, K. Trono1 1Instituto de Virología, CICVyA, INTA – Castelar. 2Cátedra de Biologia Molecular, Facultad de Ciencias Exactas, UBA. Buenos Aires, Argentina. La relación entre el genotipo y las formas de manifestación patogénica está demostrada para ciertos Retrovirus, y las zonas regulatorias Long Terminal Repeats (LTR) han sido descriptas, entre otros factores, como portadoras de determinantes de patogenia. En el caso del Virus de la Leucosis Bovina (VLB), estudios previos de secuencias llevados a cabo en nuestro laboratorio sobre las zona R-U5 de las regiones genéticas provirales LTR aisladas de 36 animales infectados naturalmente y con diferentes formas de evolución revelaron la presencia de 4 cambios fijos y característicos de provirus aislados de linfosarcoma (LS)(100%), 1 en la región R y 3 en U5. Estas modificaciones están ausentes en la mayoría (16/22) de los provirus aislados de formas asintomáticas (AL/PL). La alta asociación entre los cambios de nucleótidos y las formas de patogenia demostró la existencia de una secuencia de nucleótidos consenso y propia de los aislados de LS en la región U5 del LTR del genoma proviral de VLB. Con el objetivo de analizar si existe una capacidad diferencial de reconocimiento de factores de regulación de la transcripción celular en la célula hospedadora de las secuencias LTRs de aislamientos de distintas formas de patogenia, se utilizaron ensayos de cambio en la movilidad electroforética (EMSA). La evaluación conjunta de los resultados demuestra que existirían diferencias específicas de unión de la región U5 a proteínas del complejo de regulación de la transcripción celular denominadas E2F en relación con las diferentes presentaciones de esta patología. Estos hallazgos aportan datos en relación con la caracterización de esta co-variación de nucleótidos como marcadores de patogenia del VLB, así como también representan un adelanto en el conocimiento de la patobiología del BLV.

Repeated imaging of Jupiter's aurora has shown that the northern main oval has a distorted "kidney bean" shape in the general range of 40-100 deg magnetic longitude, which appears unchanged since 1994. More recently, improved accuracy in locating the satellite footprint auroral emissions has provided new information about the geometry of Jupiter's magnetic field in this and other areas. The persistent pattern of the main oval implies a disturbance of the local magnetic field, and the increased latitudinal separation of the locus of satellite footprints from each other and from the main oval implies a locally weaker field strength. It is possible that these phenomena result from a magnetic anomaly in Jupiter's intrinsic magnetic field, as was proposed by A. Dessler in the 1970's. There is presently only limited evidence from the scarcity of auroral footprints observed in this longitude range. Similarly, while it is difficult to observe the conjugate regions in the southern aurora, there does not appear to be any corresponding distortion in the south. We will present the observational evidence that we have accumulated to date, propose future observations to determine the nature of this disturbance, and speculate on its causes and implications.

Principal component analysis (PCA) is a ubiquitous statistical technique for data analysis. PCA is however limited by its linearity and may sometimes be too simple for dealing with real-world data especially when the relations among variables are nonlinear. Recent years have witnessed the emergence of nonlinear generalizations of PCA, as for instance nonlinear principal component analysis (NLPCA) [1] or vector quantization principal component analysis (VQPCA) [2]. VQPCA involves a two-step procedure, namely a clustering of the data space into several regions and the application of PCA in each local region. In Ref. [3], VQPCA was applied for the reconstruction of dynamical response and it was shown that it is potentially a more effective tool than conventional PCA. The purpose of this technical note is to further investigate VQPCA and to have a closer look at the choice of the distortion function used for clustering the data space. [less ▲]
