Prediction of surface roughness during hard turning of AISI 4340 steel (69 HRC)

In this study, 39 sets of hard turning (HT) experimental trials were performed on a Mori-Seiki SL-25Y (4-axis) computer numerical controlled (CNC) lathe to study the effect of cutting parameters in influencing the machined surface roughness. In all the trials, AISI 4340 steel workpiece (hardened up to 69 HRC) was machined with a commercially available CBN insert (Warren Tooling Limited, UK) under dry conditions. The surface topography of the machined samples was examined by using a white light interferometer and a reconfirmation of measurement was done using a Form Talysurf. The machining outcome was used as an input to develop various regression models to predict the average machined surface roughness on this material. Three regression models - Multiple regression, Random Forest, and Quantile regression were applied to the experimental outcomes. To the best of the authors’ knowledge, this paper is the first to apply Random Forest or Quantile regression techniques to the machining domain. The performance of these models was compared to each other to ascertain how feed, depth of cut, and spindle speed affect surface roughness and finally to obtain a mathematical equation correlating these variables. It was concluded that the random forest regression model is a superior choice over multiple regression models for prediction of surface roughness during machining of AISI 4340 steel (69 HRC).

Quality of cause-of-death reporting using ICD-10 drowning codes : a descriptive study of 69 countries

Background: The systematic collection of high-quality mortality data is a prerequisite in designing relevant drowning prevention programmes. This descriptive study aimed to assess the quality (i.e., level of specificity) of cause-of-death reporting using ICD-10 drowning codes across 69 countries.---------- Methods: World Health Organization (WHO) mortality data were extracted for analysis. The proportion of unintentional drowning deaths coded as unspecified at the 3-character level (ICD-10 code W74) and for which the place of occurrence was unspecified at the 4th character (.9) were calculated for each country as indicators of the quality of cause-of-death reporting.---------- Results: In 32 of the 69 countries studied, the percentage of cases of unintentional drowning coded as unspecified at the 3-character level exceeded 50%, and in 19 countries, this percentage exceeded 80%; in contrast, the percentage was lower than 10% in only 10 countries. In 21 of the 56 countries that report 4-character codes, the percentage of unintentional drowning deaths for which the place of occurrence was unspecified at the 4th character exceeded 50%, and in 15 countries, exceeded 90%; in only 14 countries was this percentage lower than 10%.---------- Conclusion: Despite the introduction of more specific subcategories for drowning in the ICD-10, many countries were found to be failing to report sufficiently specific codes in drowning mortality data submitted to the WHO.

Fine-needle aspiration cytology of Merkel cell carcinoma-A review of 69 cases

Background This study reviewed the clinical presentation, cytologic findings and the immunophenotype of 69 Merkel Cell Carcinoma (MCC) cases sampled by FNA. Methods Demographic and clinical data, the cytology findings and results of ancillary testing were reviewed. Results Median patient age was 78 years (37 – 104) with a 1:1.8 female to male ratio. The most common FNA sites sampled included lymph nodes in the neck, the axillary region, the inguinal region and the parotid gland. Most patients had a history of MCC (68%) &/or non-MCC malignancy (70%). The common cytologic pattern was a cellular smear with malignant cells arranged in a dispersed pattern with variable numbers of disorganised groups of cells. Cytoplasm was scant or absent and nuclei showed mild to moderate anisokaryosis, stippled chromatin, inconspicuous nucleoli and nuclear molding. Numerous apoptotic bodies were often present. Cell block samples (28 cases) were usually positive for cytokeratins in a perinuclear dot pattern, including 88% of cases with CK20 positivity. CD56 was the most sensitive (95%) neuroendocrine marker on cell blocks and was also positive with flow cytometry in 9 cases tested. Conclusions MCC is most commonly seen in FNA specimens from the head and neck of elderly patients, often with a history of previous skin lesions. Occasional cases present in younger patients and some may be mistaken for other round blue cell tumors, such as lymphoma. CD 56 may be a useful marker in cell block preparations and in flow cytometric analysis of MCC.

X-ray studies on crystalline complexes involving amino acids and peptides. XXIII. Variability in ionization state, conformation and molecular aggregation in the complexes of succinic acid with DL- and L-lysine

Crystalline complexes of succinic acid with DL- and L-lysine have been prepared and analysed by X-ray diffraction. DL-Lysine complex: C6HIsN202 + 1 2- 1 ~C4H404 .~C4H604, Mr -- 264"2, PI, a = 5"506 (4), =8.070(2), c=14.089(2) A,, a=92.02(1), /3= 100"69 (3), y = 95"85 (3) ~>, Z = 2, Dx = 1"44 g cm -3, R = 0.059 for 2546 observed reflections.

The succinic acid molecules in the structures exhibit a variety of ionization states. Two of the lysine conformations found in the complexes have been observed for the first time in crystals containing lysine. Form II of the L-lysine complex is highly pseudosymmetric. In all the complexes, unlike molecules aggregate into separate alternating layers. The basic element of aggregation in the lysine layer in the complexes is an S2-type head-to-tail sequence. This element combines in different ways in the three structures. The basic element of aggre gation in the succinic acid layer in the complexes is a hydrogen-bonded ribbon. The ribbons are interconnected indirectly through amino groups in the lysine layer.

Control de malezas en el cultivo de la soya (Glycine max L. Merril) variedad (Biloxi y hardee) 69-341

En el Centro Experimental Agropecuario La Calera, Managua, Nicaragua, se estableció en siembra de agosto a noviembre de 1976, un ensayo para determinar el tratamiento mas efectivo y rentable en el control de las malezas del cultivo de la soya (Glycine max L. Merril). Se escogió la variedad (Biloxi x Hardee) 69-341 de crecimiento determinado y ciclo vegetativo intermedio de 90-100 días. Los tratamientos que se evaluaron fueron los siguientes: Alachlor, Metribuzin, Linuron, Trifluralina, Alachlor + Metribuzin, Alachlor + Linuron, Alachlor + Trifluralina, Metribuzin + Lanuron, Metribuzin + Trifluralina, Linuron + Trifluralina en dosis de 2049,5 ml, 497,70 g, 966,00 g, 533,75 ml, 1024,75 ml + 248,85 g, 1024,75 ml + 483,00 g, 1024,75 ml + 266,87 ml, 248,85 g + 483,00 g, 248,85 g + 266,87 ml y 483,00 g, + 266,87 ml, por hectárea respectivamente, usando como comparadores un tratamiento mecánico y un testigo absoluto. Los tratamientos fueron distribuidos en un diseño de bloques completos al azar, con cuatro repeticiones. La parcela experimental consto de ocho surcos de cinco metros de largo, espaciados a cincuenta centímetros entre si y a 2,50 centímetros entre planta, correspondiendo a la parcela útil los cuatro surcos centrales a los cuales se les elimino 50,0 centímetros en cada extremo. El análisis de varianza practicado en los rendimientos de granos y en los porcentajes de control de malezas determino diferencia altamente significativa entre tratamientos al nivel de 0,01 de probabilidad de error. La mezcla de Alachlor + Metribuzin fue el tratamiento herbicida que ejerció el mayor control sobre gramíneas y hojas ancha, con 97,00 por ciento de control hasta los 60 días de emergida la soya. Los tratamientos Metribuzin, Metribuzin + Trifluralina y Alachlor fueron estadisticamente igual al nivel del 0,05 de probabilidad de error con: 74,00; 72,00 y 71;00 por ciento. Los tratamientos que menor porcentaje de control de malezas ejercieron hasta los 60 dias fueron Linuron y Linuron + Trifluralina con 34.00 por ciento. Los mayores rendimientos significativos de grano de soya, se lograron con: testigo mecanico, Alachlor + Metribuzin, Alachlor, y Alachlor + Linuron obteniendo 2,539.00, 2.294.00, 2.279.00 y 2.194.00 kilogramos por hectárea respectivamente. Los menores rendimientos correspondieron a: Trifluralina con 1,103.00 hectarea y testigo absoluto con 844.00 por hectarea. El analisis economico de los rendimientos por tratamiento, revelo que los mayores ingresos netos se obtuvieron con: testigo mecánico, Alachlor + Metribuzin, y Alachlor y Alachlor + Linuron de: 1,945.22, 1,800.12, 1,771.87 y 1,668.31 córdobas por hectárea respectivamente, pero la mayor relación beneficio-costo se logro con los tratamientos Alachlor, Alachlor + Metribuzin, testigo mecánico y Alachlor + Linuron, con 2.31, 2.30, 2.23 y 2.21 respectivamente.

Diário da Constituinte [gravação de vídeo] : [programa n. 059]

Cristina Tavares (PMDB-PE), relatora da Subcomissão da Ciência e da Comunicação da Assembleia Nacional Constituinte (ANC), adia o parecer final. No primeiro relatório foi pedida a reserva de mercado para a tecnologia brasileira e criação de um Conselho Nacional de Comunicação. No anteprojeto da Subcomissão da Educação, Cultura e Esportes foi feita a proposta de aumentar o percentual de verbas para a educação de 13% para 18%. Lourenberg Rocha (PMDB-MT) acredita que este é um passo para reerguer o país. A Subcomissão de Orçamento e Fiscalização Financeira analisa as propostas de gastos públicos, redistribuição de renda e controle de emissão de moedas. José Luiz Maia (PDS/PI) diz que o controle de gastos públicos deve passar por uma fiscalização rigorosa. A Subcomissão dos Municípios e Regiões cria o Conselho de Ouvidores do Município, formado por moradores, com o objetivo de fiscalizar os atos do prefeito, gastos do município e as prestação de serviços. Aloysio Chaves (PFL-BA) diz que a medida fortalece o município. Maurício Fruet (PMDB-PR) diz que a proposta ainda é tímida. A Subcomissão dos Direitos Políticos analisa o direito do eleitor, que é a fiscalização dos deputados e senadores e o direito dos eleitores revogarem os mandatos. Populares falam a respeito. Raimundo Rezende (PMDB-PR) concorda com a proposta. Francisco Diógenes (PDS-AC) acha que se o povo não concordar com as ações do parlamentar o mandato não será renovado. Lysâneas Maciel (PDT-RJ) acredita que o povo deve intervir antes do fim do mandato.
