The axial self-infeed rolling process is an advanced and efficient process to form long threads such as lead screw and thread shaft. The experiments of axial self-infeed rolling process for the stainless steel were conducted with three blank diameters, forming speeds and two lubrication conditions. The effects of forming speed, blank diameter and lubrication condition on forming torque, microhardness and tooth height of forming threads were analyzed by the design of experiment and analysis of variance. And the characteristics of forming torque, microhardness distribution and tooth height were

Features and requirements to the use of reheating of ring blanks in the conditions of production on the automated line are considered. An assessment is given for a technological temperature state of ring blanks at various stages of production under conditions of the automated line. For assessment of rational for reheating at production of ring blanks, a classification of ring manufacturing technology is proposed with the production of a pressed non-core blank in an open die, with the production of a pressed profile blank in a closed die, with the production of a pressed profile blank in a stam

An important problem in obtaining mini drawn parts with high precision is represented by the blank geometry. Utilization of a blank with optimal shape and dimensions leads to the following benefits: improves the accuracy of the drawn parts and determine the costs reduction due to reduced material consumption and cost, lower number of technologic operations, shorter manufacturing times etc. An adequate blank prevents the following effects on drawn part: avoids the part fracture, conducts to a uniform distribution of the material thickness in drawn part and reduces the blank holder force require

The paper's goal was achieved through comprehensive tests on root systems of eight relatively common in the Polish Flysch Carpathians tree species. The tests that were carried out included field work, laboratory work and analytical calculations.

Mistbows and glories are both atmospheric optical effects formed by light scattered by extremely small water droplets, having diameters comparable to the wavelength of light. Yet these two phenomena affect light in very different ways. In the case of mistbows the diffractive spreading of light caused by its passage through the very small droplets (which act somewhat like tiny apertures) causes the light to diffract in a wide angle that compensates for the prismatic separation of color. The different bands of colors overlap, and as a result the “rainbow” arcs are colorless. Glories are also Eff

A second drummer, holding his instrument between his knees, joins in, playing with the same staccato attack.

HFRP samples produced continuous brown ribbon-like chips, which were short and melted at lower feed rate and cutting speed, implying that higher feed rate and cutting speed produced wider, longer and lighter chips.

Several aspects of Incremental Forming, an innovative sheet-metal-forming process, were studied. Firstly, an optimal combination of tool and lubricant was explored to form the TA1 (commercial Titanium) sheet-metal parts. Secondly, the effect of the tool diameter on the surface texture of a part was investigated. In addition to this, the influence of the tool diameter on in-plane strain distribution and thickness distribution along a part was also studied. Lastly, experiments were conducted in order to investigate the influence of half-apex angle on thickness distribution along a part to be for

The models used at present to evaluate the potential hazard areas around large LNG fires were developed with field test data from smaller diameter (1.8 m to 15 m) fires. These models are, however, applied to predict hazard distances from fires much larger in size compared to the experimental fires. Recent publication of the results from a series of tests conducted in 1987 with 35 m diameter LNG fires indicates that large LNG fires tend to generate significant amount of black soot. The black soot is postulated to be generated from incomplete and inefficient combustion of fuel vapors due to redu

Beside carbon black, silica powder is the other important filler used to reinforce various colored rubber products. In order to improve the compatibility between silica particles and rubber phase, this work has focused on preparing an NR composite, reinforced by silica generated inside the NR matrix or ‘in situ’. The silica particle was formed by a sol-gel process of tetraethoxysilane (TEOS) dispersed in NR latex. The latex used was concentrated latex having 60% rubber content, and already contained water and ammonia, two ingredients needed for the sol-gel reaction. The conversion of TEOS to s

The black carp (bc)GtH IIb cDNA was amplified and isolated, cloned and sequenced. Comparison of the bcGtH IIb deduced a.a. sequence with that of GtH IIb from other teleosts revealed high homology to cyprinid species and a lower homology to salmonid or perciform fish. The gene coding for the GtH IIb was isolated and sequenced. Three bc recombinant phages which hybridized to the goldfish GtH Ib cDNA probe were isolated and are currently being characterized. The region coding for the mature GtH IIb was expressed in a bacterial expression vector resulting in the production of a recombinant protein

Both the genes and cDNA sequences encoding the b-subunits of black carp LH and FSH were isolated, cloned and sequenced. Sequence analysis of the bcFSHb and LHb5'flanking regions revealed that the promoter region of both genes contains canonical TATA sequences, 30 bp and 17 bp upstream of the transcription start site of FSHb and LHb genes, respectively. In addition, they include several sequences of cis-acting motifs, required for inducible and tissue-specific transcriptional regulation: the gonadotropin-specific element (GSE), GnRH responsive element (GRE), half sites of estrogen and androgen

The Mississippi National River and Recreation area (MISS), situated along a 116 km stretch of the Mississippi River through the Minneapolis and St. Paul urban corridor, encompasses ~21,800 ha of public and private land. In 2022, the Great Lakes Inventory and Monitoring Network (GLKN) resampled permanent forest monitoring sites in the park, marking the second assessment of these sites, which were established and initially sampled in 2011. The goal of this long-term monitoring project is to provides managers with routine updates on which to base management decisions; these data can also be used
