Public Attention and Financial Information as Determinants of Firms Performance in the Telecommunication Sector

The remarkable progress of information technology had driven every firm to publish their financial performanceby using internet. This circumstance resulted in the high public attention in order to generate the stockreturn. In addition, financial information such as financial ratio namely DER, LEV, NPM, ROI, and ROEwere supposed to influence the firm\u27s performance either in positive or negative effects. This study focused onthe investigation of public attention (PA) and financial information as determinants of financial performanceon four companies in Telecommunication sector, Indonesia Stock Exchange (IDX), within time period from2007 to 2012. Hereby, we pointed out that public attention and financial information considerably contributeto firm performance, in which the Pooled Least Square (EGLS) with cross section and period weight wasemployed. The results showed that Public Attention (PA) positively contributed towards stock return. Further,financial ratio such as debt-to-equity ratio (DER) negatively influenced the return. Leverage (LEV), net profitmargin (NPM) and return on investment (ROI) positively related to return. However, return on equity (ROE)showed the contrary sign, in which it negatively influenced the return but was statistically insignificant. Then,we reported that the stock price (LNSP) did not significantly contribute towards return (RET)

Morphological and molecular characterization of a new species of Isospora Schneider, 1881 (Apicomplexa: Eimeriidae) from the western wattlebird Anthochaera lunulata Gould in Western Australia

A new coccidian species, Isospora lunulatae n. sp., from the western wattlebird Anthochaera lunulata Gould in Western Australia is described and characterised molecularly. Microscopic analysis of a faecal sample identified subspheroidal oöcysts measuring 27–34 × 26–31 (30.6 × 29.4) μm (n = 20), with a length/width (L/W) ratio of 1.0–1.1 (1.0). Oöcysts have a bi-layered wall, 0.9–1.2 (1.0) μm thick; the outer layer is smooth, representing c.2/3 of total thickness. Micropyle and oöcyst residuum are both absent, but a polar granule is present. Sporocysts are ovoidal, 17–19 × 10–12 (18.3 × 10.7) μm, with a L/W ratio of 1.6–1.8 (1.7) and occupying about 21% of the area (each one) within the oöcyst. Stieda body is flattened to rounded, measuring on average 0.9 × 1.8 μm; sub-Stieda body is rounded to rectangular, measuring on average 1.5 × 2.6 μm; para-Stieda body is absent. Sporocyst residuum has an irregular shape consisting of numerous granules and appears membrane-bound. Sporozoites are vermiform 12.8 × 3.0 μm on average, with prominent striations at the more pointed end and two refractile bodies below striations. Segments of three gene loci (18S rRNA, 28S rRNA and cox1) were sequenced and I. lunulatae n. sp. exhibited 99.6% genetic similarity to Isospora phylidonyrisae Yang, Brice, Berto & Ryan, 2021 at the 18S rRNA gene locus, 99.8% genetic similarity to Isospora anthochaerae Yang, Brice & Ryan, 2014 and shared a 98.1% genetic similarity with Isospora manorinae Yang, Brice, Jian & Ryan, 2016 at the cox1 gene locus. Morphological and molecular data support the distinct species status of the new species

Hybrid manufacturing of steel construction parts via arc welding of LPBF-produced and hot-rolled stainless steels

The demand for free-form steel structures having improved performances, reducing labour and resource usage is increasing in the construction sector. Structural nodes are some of the most critical regions for steel structures characterised often by large dimensions. These nodes can exploit the geometrical freedom of metal additive manufacturing (MAM) processes. Laser powder bed fusion (LPBF) is arguably the most developed MAM process, which has limitations regarding the size of the parts to be produced. A way to overcome the size limits of LPBF for producing structural nodes while still exploiting its geometrical capacity is producing hybrid components by welding them to traditionally manufactured beams. Such hybrid joints would constitute a complex system from a mechanical design perspective requiring a systematic analysis in order to be certified for structural use. Accordingly, this work studies the mechanical behaviour of hybrid steel components generated by welding LPBF plates and quarto plates made of AISI 316L stainless steel. The work was guided by a case study based on a large steel node, which helped defining the requirements to fill the gap of the international standards. The mechanical characterisation of LPBF-produced plates and quarto plates, as well as the welded hybrid components revealed a maximum of 10% difference between the properties of the differently manufactured plates. Through the digital image correlation (DIC) analyses, the anisotropic deformation behaviour along the LPBF, weld seam, and quarto plate regions have been identified, and the properties after welding did not show relevant modifications. The tests allowed to define that the failure behaviour is mainly governed by interlayer bounds, and a 0.9 safety reduction parameter for considering the reduction of ductility induced by arc welding to LPBF. Finally, design and production suggestions have been provided for a correct evaluation of gross and effective sections of the designed nodes

Eimeria spp. and Tyzzeria perniciosa Allen, 1936 (Apicomplexa: Eimeriidae) from a Pacific black duck, Anas superciliosa Gmelin (Aves: Anseriformes), in western Australia

Four species of the Eimeriidae, Eimeria anatis Scholtyseck, 1955, Eimeria aythyae Farr, 1965, Eimeria krylovi Svanbaev & Rakhmatullina, 1967 and Tyzzeria perniciosa Allen, 1936, were morphologically identified from oöcysts recovered from a Pacific black duck, Anas superciliosa Gmelin. Additionally, genotypic characterization of E. anatis is provided via sequencing of the mitochondrial cytochrome c oxidase subunit 1 (cox1) and the small subunit ribosomal RNA (18S) genes. The four species are redescribed, providing additional morphological details. The validity of genera and coccidian species parasitizing birds of the order Anseriformes such as Wenyonella Hoare, 1933 and some Tyzzeria spp. are discussed. Molecular phylogenetic analyses for the cox1 and 18S rRNA genes resulted in monophylies of Eimeria spp. from Anseriformes which included the sequences obtained from E. anatis oöcysts

Residual Stress Distribution in Selective Laser Melting of SS316L Parts

Additive manufacturing is one of the fastest-growing fields in materials engineering. This is because there is a new trend for custom, high-precision, and on-demand manufacturing. The undesired residual stress induced in the components during layer-by-layer melting and solidification of the metal powder is an important issue related to the selective laser melting (SLM) process that needs to be studied deeply. These stresses may impair mechanical performance and potentially result in premature failure. As a result, a thorough knowledge of residual stress is crucial for improved component dependability. By keeping constant process parameters, samples were produced with a difference in the scanning method. Results indicate that the defect-free parts are manufactured in all the four patterns used, and the self-balanced residual stresses are within the safe limits of yield strength
