La titulatura faraònica dels emperadors romans: un cas particular de la imitatio Alexandri

Estudi realitzat a partir d’una estada a la University of Oxford, Gran Bretanya, entre 2010 i 2012. Durant l’estada postdoctoral a la University of Oxford s’han efectuat dos estudis relacionats amb l’onomàstica dels faraons d’Egipte i que constitueixen una continuació de l’anàlisi de la titulatura d’Alexandre el Gran realitzada prèviament per l’investigador en la seva recerca doctoral. El primer estudi examina la titulatura faraònica dels emperadors romans en comparació amb la d’Alexandre i, en especial, la significació ideològica i política dels paral•lelismes onomàstics existents entre elles, els quals han estat analitzats en el marc de la imitatio-aemulatio-comparatio Alexandri. Per al cas d’August, s’ha arribat a la conclusió que l’adopció de determinats apel•latius egipcis utilitzats anteriorment per Alexandre pot ser interpretada com un exemple local o estrictament egipci d’imitatio Alexandri, mentre que, en relació amb la resta d’emperadors, atès que les seves titulatures faraòniques es basen o imiten la del primer emperador, aquestes represes han de ser vistes més aviat com un exemple d’imitatio (o comparatio) Augusti. El segon estudi versa sobre la titulatura faraònica egípcia i la tradició annalística. A partir d’una anàlisi comparativa dels protocols onomàstics dels fundadores de cadascuna de les dinasties, s’ha intentat determinar si determinats noms o epítets s’empren de forma recurrent i d’una manera deliberada per tal de senyalar canvis dinàstics, és a dir, noves realitats polítiques. En concret, s’ha pretès establir fins a quin punt determinats recursos onomàstics tenen el seu reflex en la divisió en dinasties de Manetó i, alhora, determinar en quina mesura l’estudi de l’onomàstica faraònica pot contribuir al coneixement de com els egipcis conceptualitzaren i organitzaren el seu propi passat.

Generic approach for the sensitive absolute quantification of large undigested peptides in plasma using a particular liquid chromatography-mass spectrometry setup.

A generic LC-MS approach for the absolute quantification of undigested peptides in plasma at mid-picomolar levels is described. Nine human peptides namely, brain natriuretic peptide (BNP), substance P (SubP), parathyroid hormone 1-34 (PTH), C-peptide, orexines A and B (Orex-A and -B), oxytocin (Oxy), gonadoliberin-1 (gonadothropin releasing-hormone or luteinizing hormone-releasing hormone, LHRH) and α-melanotropin (α-MSH) were targeted. Plasma samples were extracted via a 2-step procedure: protein precipitation using 1vol of acetonitrile followed by ultrafiltration of supernatants on membranes with a MW cut-off of 30 kDa. By applying a specific LC-MS setup, large volumes of filtrates (e.g., 2×750 μL) were injected and the peptides were trapped on a 1mm i.d.×10 mm length C8 column using a 10× on-line dilution. Then, the peptides were back-flushed and a second on-line dilution (2×) was applied during the transfer step. The refocalized peptides were resolved on a 0.3mm i.d. C18 analytical column. Extraction recovery, matrix effect and limits of detection were evaluated. Our comprehensive protocol demonstrates a simple and efficient sample preparation procedure followed by the analysis of peptides with limits of detection in the mid-picomolar range. This generic approach can be applied for the determination of most therapeutic peptides and possibly for endogenous peptides with latest state-of-the-art instruments.

Apoplastic polyesters in Arabidopsis surface tissues--a typical suberin and a particular cutin.

Cutinized and suberized cell walls form physiological important plant-environment interfaces as they act as barriers limiting water and nutrient loss and protect from radiation and invasion by pathogens. Due to the lack of protocols for the isolation and analysis of cutin and suberin in Arabidopsis, the model plant for molecular biology, mutants and transgenic plants with a defined altered cutin or suberin composition are unavailable, causing that structure and function of these apoplastic barriers are still poorly understood. Transmission electron microscopy (TEM) revealed that Arabidopsis leaf cuticle thickness ranges from only 22 nm in leaf blades to 45 nm on petioles, causing the difficulty in cuticular membrane isolation. We report the use of polysaccharide hydrolases to isolate Arabidopsis cuticular membranes, suitable for depolymerization and subsequent compositional analysis. Although cutin characteristic omega-hydroxy acids (7%) and mid-chain hydroxylated fatty acids (8%) were detected, the discovery of alpha,omega-diacids (40%) and 2-hydroxy acids (14%) as major depolymerization products reveals a so far novel monomer composition in Arabidopsis cutin, but with chemical analogy to root suberin. Histochemical and TEM analysis revealed that suberin depositions were localized to the cell walls in the endodermis of primary roots and the periderm of mature roots of Arabidopsis. Enzyme digested and solvent extracted root cell walls when subjected to suberin depolymerization conditions released omega-hydroxy acids (43%) and alpha,omega-diacids (24%) as major components together with carboxylic acids (9%), alcohols (6%) and 2-hydroxyacids (0.1%). This similarity to suberin of other species indicates that Arabidopsis roots can serve as a model for suberized tissue in general.

TOPSpro Data Dictionary, July 1, 2005–June 30, 2006

The passage of the Workforce Investment Act (WIA) of 1998 [Public Law 105-220] by the 105th Congress has ushered in a new era of collaboration, coordination, cooperation and accountability. The overall goal of the Act is “to increase the employability, retention, and earnings of participants, and increase occupational skill attainment by participants, and, as a result improve the quality of the workforce, reduce welfare dependency, and enhance the productivity and competitiveness of the Nation.” The key principles inculcated in the Act are: • Streamlining services; • Empowering individuals; • Universal access; • Increased accountability; • New roles for local boards; • State and local flexibility; • Improved youth programs. The purpose of Title II, The Adult Education and Family Literacy Act (AEFLA), of the Workforce Investment Act of 1998 is to create a partnership among the federal government, states, and localities to provide, on a voluntary basis, adult education and literacy services in order to: • Assist adults become literate and obtain the knowledge and skills necessary for employment and self-sufficiency; • Assist adults who are parents obtain the educational skills necessary to become full partners in the educational development of their children; • Assist adults in the completion of a secondary school education. Adult education is an important part of the workforce investment system. Title II restructures and improves programs previously authorized by the Adult Education Act. AEFLA focuses on strengthening program quality by requiring States to give priority in awarding funds to local programs that are based on a solid foundation of research, address the diverse needs of adult learners, and utilize other effective practices and strategies. To promote continuous program involvement and to ensure optimal return on the Federal investment, AEFLA also establishes a State performance accountability system. Under this system, the Secretary and each State must reach agreement on annual levels of performance for a number of “core indicators” specified in the law: • Demonstrated improvements in literacy skill levels in reading, writing, and speaking the English language, numeracy, problem solving, English language acquisition, and other literacy skills. • Placement in, retention in, or completion of postsecondary education, training, unsubsidized employment or career advancement. • Receipt of a secondary school diploma or its recognized equivalent. Iowa’s community college based adult basic education program has implemented a series of proactive strategies in order to effectively and systematically meet the challenges posed by WIA. The Iowa TOPSpro Data Dictionary is a direct result of Iowa’s pro-active efforts in this educational arena.

The purpose of the Iowa TOPSpro Data Dictionary is to provide a statewide-standardized set of instructions and definitions for coding Tracking Of Programs And Students (TOPSpro) forms and effectively utilizing the TOPSpro software. This document is designed to serve as a companion document to the TOPS Technical Manual produced by the Comprehensive Adult Student Assessment System (CASAS). The data dictionary integrates information from various data systems to provide uniform data sets and definitions that meet local, state and federal reporting mandates. The sources for the data dictionary are: (1) the National Reporting System (NRS) Guidelines, (2) standard practices utilized in Iowa’s adult literacy program, (3) selected definitions from the Workforce Investment Act of 1998, (4) input from the state level Management Information System (MIS) personnel, and (5) selected definitions from other Iowa state agencies.

Situación de los recursos Anchoveta (Engraulis Ringens) y Sardina (Sardinops sagax) a principios de 1994 y perspectivas para la pesca en el Perú, con particular preferencia a las regiones norte y centro de la costa peruana

Se analizan los cambios en los niveles poblacionales de anchoveta ( Engraulis ringens), entre 1961-1994 y sardina (Sardinops sagaX") entre 1978-1994, en la parte del mar peruano comprendido entre los 03 º23'S y los 14°S. Los resultados de los análisis de cohortes y la observación de información complementaria indican que la población de anchoveta muestra una tendencia ascendente, habiendo alcanzado niveles de biomasa total próximos al os 10 millones de toneladas, y encontrándose en recuperación luego de los valores mínimos históricos alcanzados entre 1975-1 984. la sardina en cambio, ha venido disminuyendo desde 1987. Se anal izan los cambios y fluctuaciones en la abundancia de estas dos especies, y se postula la ocurrencia de un cambio de "régimen" poblacional para la anchoveta, cuya población se encontraría en un nivel todavía no bien consolidado, entre un régimen medio, correspondiente al nivel de la fases de pre y post colapso, y un nivel de máxima abundancia. Se analizan las causas probables de la declinación del stock de sardina y se dan recomendaciones para el ordenamiento de la pesquería a corto y mediano plazo de estas dos especies.

A solução particular de equações diferenciais

O tema das equações diferenciais está presente na esmagadora maioria dos planos de estudos dos cursos de licenciatura onde se estudam temas matemáticos. E o mesmo acontece no âmbito de muitos cursos de mestrado e até de doutoramento. De resto, o tema continua em franco desenvolvimento, muito em particular no subdomínio das equações diferenciais às derivadas parciais, e mormente ao nível das aplicações a casos concretos.

detenção e a sua prática em Cabo Verde – O caso particular da Cidade da Praia

O presente estudo faz uma abordagem da prática da detenção em Cabo Verde. Apesar de não existir informações disponíveis sobre as estatísticas das detenções ilegais em Cabo Verde, a verdade é que frequentemente presenciamos situações que nos afiguram, no mínimo, como sendo uma privação ilegal da liberdade de outrem. Assim, consciente da existência de um número significativo de detenções ilegais, a obtenção dos dados processou-se mediante a aplicação de um inquérito por questionário a 28 agentes da Policia Nacional, sendo 24 agentes da Piquete da Esquadra da PN do Palmarejo e 4 agentes da Brigada Anti-crime e de Investigação Criminal na cidade da Praia. Os resultados deste estudo indicam que as detenções ilegais verificadas na Cidade da Praia estão intimamente ligadas ao diminuto conhecimento jurídico de quem as efectua.

Clearing and dissecting insects for internal skeletal morphological research with particular reference to bees

ABSTRACT A detailed protocol for chemical clearing of bee specimens is presented. Dry specimens as well as those preserved in liquid media can be cleared using this protocol. The procedure consists of a combined use of alkaline solution (KOH or NaOH) and hydrogen peroxide (H2O2), followed by the boiling of the cleared specimens in 60–70% EtOH. Clearing is particularly useful for internal skeletal morphological research. This procedure allows for efficient study of internal projections of the exoskeleton (e.g., apodemes, furcae, phragmata, tentoria, internal ridges and sulci), but this process makes external features of the integument, as some sutures and sulci, readily available for observation as well. Upon completion of the chemical clearing process the specimens can be stored in glycerin. This procedure was developed and evaluated for the preparation of bees and other Apoidea, but modifications for use with other insect taxa should be straightforward after some experimentation on variations of timing of steps, concentration of solutions, temperatures, and the necessity of a given step. Comments on the long-term storage, morphological examination, and photodocumentation of cleared specimens are also provided.

Role of substrate utilization and thermogenesis on body-weight control with particular reference to alcohol.

Alcohol (ethanol; EtOH) provides fuel energy to the body (29.7 kJ (7. 1 kcal)/g, 23.4 kJ (5.6 kcal)/ml), as do other macronutrients, but no associated essential nutrients. The thermogenic effect of EtOH (on average 15 % of its metabolizable value) is much greater than that of the main substrates utilized by the body, i.e. fat and carbohydrates (CHO), suggesting a lower net efficiency of energy utilization for EtOH than for fat and CHO. EtOH cannot be stored in the body and is toxic, so that there is an obligatory continuous oxidation of EtOH and it becomes the priority fuel to be metabolized. In contrast to CHO, its rate of oxidation does not depend on the dose ingested. As with CHO intake, it engenders a shift in postprandial substrate utilization (decrease in fat oxidation), but by a non-insulin-mediated mechanism. A limited amount of EtOH can be converted to fatty acids by hepatic de novo lipogenesis (as occurs with high levels of CHO feeding) from acetate production, which inhibits lipolysis in peripheral tissues. There is no evidence that EtOH consumed under normoenergetic conditions (i.e. isoenergetically replacing CHO or fat) leads to greater body fat storage than fat or CHO. However, there is still a lack of experimental studies on the influence of EtOH on the level of spontaneous physical activity in man. This effect may well depend on the dose of EtOH consumed as well as other intrinsic factors.

Pure monoparesis: a particular stroke subgroup?

BACKGROUND: Acute stroke presenting as monoparesis is rare, with a pure motor deficit in the arm or leg extending to an isolated facial paresis. OBJECTIVE: To raise the question if acute stroke presenting as monoparesis is a different entity from stroke with a more extensive motor deficit. PATIENTS: In the Lausanne Stroke Registry (1979-2000), 195 (4.1%) of 4802 patients met the clinical criteria for pure monoparesis involving the face (22%), arm (63%), or leg (15%). RESULTS: In the vast majority of cases (> 95%), monoparesis corresponded to ischemic stroke with a favorable outcome, with initial computed tomography scans or magnetic resonance images showing no signs of hemorrhage. The lesion for a facial deficit was most frequently located subcortically (internal capsule); for an arm deficit, in the superficial middle cerebral artery; and for a leg deficit, in the anterior cerebral artery territory. In pure monoparesis, only 17% of the patients had more than 1 risk factor as compared with 26% of those with bimodal and trimodal hemiparesis and with 46% of all patients with stroke other than those with pure motor stroke. The only frequent risk factor was hypertension (53%); however, this frequency was no different from that in other patients with stroke. No major stroke etiology could be identified in any of the 3 subgroups of monoparesis. CONCLUSION: Our finding of a wide range of stroke localization and etiology in monoparesis without any particular subgroup suggests that no specific plan of investigation can be recommended for these patients.
