Abstract:

By the summer of 1929, Norman Rockwell was a full-fledged success. At age thirty-five, he had been creating covers for the Saturday Evening Post for thirteen years. A generation of American youth had grown up beguiled by his illustrations for Boys' Life, St. Nicholas, and the Boy Scouts' calendar. For more than a decade, Rockwell's artistry had helped sell Adams Black Jack gum, American Mutual insurance, Sun Maid raisins, and Coca-Cola. As this commercial success modulated into social success, Rockwell, whose father had risen to middle-class respectability in the offices of a New York City textile firm, found himself living the good life in the artists' colony of suburban New Rochelle. The drab apartments and boardinghouses of his youth and adolescence had been left behind. He joined the Larchmont Yacht Club, golfed in clothes from Brooks Brothers, and hosted elaborate parties worthy of Jay Gatsby.

Abstract:

The Norman Rockwell image of the American physician who fixed the broken arm of a child, treated the father for hypertension, and brought an unborn child into this world is now almost nonexistent. Since the time of the Rockwell portrait, a highly technical medical industry has evolved. Now two-thirds of physicians are board certified in subspecialties, and patients visit an average of 3–4 different physicians per year. Today's physicians see themselves less as “benevolent and wise counselors overseeing the patient's welfare and more as objective scientists applying the latest technical methods to bring about the desired end.” The intimate patient-physician relationship that was once the norm in our society is rapidly disappearing.

Abstract:

The cover of the may 29, 1943, Saturday Evening Post depicts our most famous image of Rosie the Riveter, a name that came to symbolize women's crossover into male-dominated industrial work during World War II (Figure 1). Norman Rockwell positioned his Rosie resting during her lunch break, calmly eating a bologna sandwich while stomping on a copy of Mein Kampf with author's name, Adolf Hitler, and Nazi swastika visible under the title. It was an image meant to reassure the American public that women would get the job done on America's home front and help defeat the Axis powers. It is also an image worth examining today for it captures some of the contradictions that continue to vex us concerning the war's multifaceted representations of women and work, portrayals that contained and excluded even as they widened public perceptions of what women could do. For one thing, Rockwell's Rosie is notably “unfeminine” in that her muscular arms are unadorned with jewelry, she wears a double-banded leather watch, she has on comfortable loafers to match her denim overalls, and her ruddy complexion seems the product of exertion, not makeup. Furthermore, she is indifferent to our gaze; rather her proud stare announces absorption in a more compelling subject, symbolized by the American flag that forms the backdrop for her portrait.

Abstract:

Purpose This paper aims to examine how and why finance is represented in cultural products. Focussing on an illustration by Norman Rockwell for the cover of The Saturday Evening Post, this analysis suggests that financialization is represented through the technique of visually incongruent humour. Humour relays the cultural value of the separation of work and play, and financialization is a tool to make sense of play as work. Addressing why certain financial representations are produced highlights the influence of finance in determining how and what messages about financialization are made public. This analysis of a single illustration suggests a need for further research into comparative and contextual studies of culture and finance. Design/methodology/approach This paper is a qualitative analysis of The Expense Account (1957), a cover illustration for The Saturday Evening Post. Findings In analysing the visually incongruent humour of the illustration, the cultural value of the separation of work and play is muddied by the lack of supervision and undefined organizational space. Freedom of travel and lack of managerial presence suggest that travelling salesmen face anxiety and uncertainty in having to account for their fun activities as work. Accounting is one tool of financialization used to interpret play as work by employees. This illustration was produced in a for-profit context and was therefore influenced by the financial decisions of magazine editors and customers. Practical implications Interdisciplinary qualitative analysis of finance and humorous popular cultural images suggests that accounting is a financial tool for making sense of play as work outside fixed organizational spaces. Additional support is given for studying popular culture and finance together, as popular culture is produced within a financial system in which financial decisions determine humorous representations of financialization. Originality/value This paper adopts a financial perspective in examining a Norman Rockwell illustration and makes the case for examining how representations of financialization are made by humour and financial influence.

Abstract:

Not so very long ago, the idea of religious freedom enjoyed all the self-evident virtue of a Norman Rockwell painting. Sure, Americans disagreed about what it meant in practice, leaving their Supreme Court to hash out the details. Still, however Americans differed in their religious beliefs, they espoused religious freedom and insisted that it cannot be government's job to promote any one religious sect over others or coerce anyone's conscience in religious matters. “If there is any fixed star in our constitutional constellation,” thundered Supreme Court Justice Robert Jackson in 1943, “it is that no official, high or petty, can prescribe what shall be orthodox in politics, nationalism, religion, or other matters of opinion or force citizens to confess by word or act their faith therein.”1For a time, this consensus seemed poised to embrace the entire world. When in November 1949 Eleanor Roosevelt proudly held up for public view a poster-size copy of the Universal Declaration of Human Rights, including its article on “freedom of thought, conscience and religion,” one might have been forgiven for thinking that all the peoples of the earth were ready to follow her matronly instruction.2

Abstract:

Aiming at improving their tribological behaviors, adhesion of diamond-like carbon (DLC) films on high-speed steel was investigated by varying doping silver (Ag) contents in a mid-frequency dual-magnetron sputtering system. Scratch testing was performed on the Ag-DLC films under a progressive normal load from 3 to 80 N, along with a Rockwell C indenter at a relative displacement speed for a Rockwell testing. A microscopic analysis of the scratch evolution under a progressive normal load permits identification of the various traces and the damage mechanisms of the films. A process of the film adhesion failure typically in turn appears like this, germination of the cracks along the longitudinal edges of the scratch traces; propagation in front of the indenter; and, detachment in the subsurface by shearing. An Ag-DLC film of 15.2 at% Ag exhibits a superior adherence on the steel substrate as compared with the three Ag DLC films of the other doping silver contents.

The scratch resistance of the silicon nitride with the addition of 1 and 7 wt% of graphene multiplatelets prepared by hot press sintering has been studied. The scratch resistance behaviour of Si3N4-GNP composites were investigated using a Rockwell indenter for normal applied loads ranging from 1-150 N. Si3N4-7-wt%GNP composite behaved differently during the scratch test depending on the normal applied load. The coefficient of friction changed dramatically at higher load and extensive crack propagation resulting in the chipping is observed.

Abstract:

To address the concern that irrigation provides sufficient water to match the crop needs, while not impeding oxygen availability to the roots, we conducted an experiment to develop suitable irrigation schedule(s) for greenhouse tomato (Lycopersicon esculentum Mill.) on rockwool. The experimental treatments incorporated the electrical conductivity (EC) of the nutrient solution in the rockwool slab (slab-EC) along with the water content (WC) in the rockwool slab (slab-WC) as the irrigation decision-making variables. They were: slab-WC ≤ 70% or slab-EC ≥ 1.4× normal or more (T1), slab-WC ≤ 70% or slab-EC ≥ 1.7× normal or more (T2), slab-WC ≤ 80% or slab-EC ≥ 1.4× normal or more (T3), slab-WC ≤ 80% or slab-EC ≥ 1.7× normal or more (T4), and the combined weight loss (WL) 700 g or more (T5) and WL 500 g or more (T6), in which “normal” means the feed solution EC as recommended in the seasonal fertigation schedule for a spring–summer tomato crop. The data on early-season marketable yield, total seasonal marketable yield, and fruit grades indicated the superiority of treatments T1, T2, and T6 over T3, T4, and T5. Better root growth was observed with T1, T2, and T6 and this was also associated with minimized nutrient solution leaching; furthermore, these plants had an abundance of coarse and fine roots, higher photosynthesis and transpiration, higher marketable yield, and a higher water use efficiency. Our results thus established that irrigation based on either a slab water content 70% or less or a 500-g weight loss is the best strategy for rockwool-grown greenhouse tomatoes in the spring–summer season. A variation in slab-EC between 1.4 and 1.7× normal, at a slab-WC of 70% or less, would have no significant effect on root growth, water use, marketable yield, or fruit grades.

Full text

Abstract:

A new test method based on multipass scratch testing has been developed for evaluating the mechanical and tribological properties of thin, hard coatings. The proposed test method uses a pin-on-disc tribometer and during testing a Rockwell C diamond stylus is used as the “pin” and loaded against the rotating coated sample. The influence of normal load on the number of cycles to coating damage is investigated and the resulting coating damage mechanisms are evaluated by posttest scanning electron microscopy. The present study presents the test method by evaluating the performance of Ti0.86Si0.14N, Ti0.34Al0.66N, and (Al0.7Cr0.3)2O3coatings deposited by cathodic arc evaporation on cemented carbide inserts. The results show that the test method is quick, simple, and reproducible and can preferably be used to obtain relevant data concerning the fatigue, wear, chipping, and spalling characteristics of different coating-substrate composites. The test method can be used as a virtually nondestructive test and, for example, be used to evaluate the fatigue and wear resistance as well as the cohesive and adhesive interfacial strength of coated cemented carbide inserts prior to cutting tests.

Abstract:

3D Printed Concrete (3DPC) technology is currently evolving with high demand amongst researches and the integration of modular building system (MBS) with this technology would provide a sustainable solution to modern construction challenges. The use of lightweight concrete in such innovative construction methods offers lightweight structures with better heat and sound insulation compared to normal weight concrete. It is worth noting that fire and energy performance has become central to building design. However, there are limited research studies on the combined thermal energy and fire performance of 3DPC walls. Therefore, this study investigates fire performance of 20 numbers of varying 3DPC wall configurations using validated finite element models under standard fire conditions. The fire performance analysis demonstrated that 3DPC non-load bearing cavity walls have substantial resistance under standard fire load and its performance can be further improved with Rockwool insulation. There is significant improvement in terms of fire performance when the thickness of the walls increases in a parallel row manner. Previous thermal energy investigation also showed a lower U-value for increased thickness of similar 3DPC walls. This research concludes with a proposal of using 3DPC wall with Rockwool insulation for amplified combined thermal energy and fire performance to be used in MBS.

It must have high strength, good hardness, good wear and corrosion resistance to withstand high pressure. Poor ejector pin may result in defect of finished product and delay the process due to additional time was required to release sticking product in the mould. The aim of this research is to select proper material for the ejector pin and analyse it not to experience plastic deformation. Three specimens’ steel was considered for making the pin, SUS 304, normal SKS 3 and heat treated SKS 3. Hardness and tensile test were used to examine the mechanical properties of specimens and impact was utilized to obtain impact energy using Charpy method. Static stress analysis was also used to simulate the working load using SolidWorks. Rockwell hardness test recorded that SUS 304, normal SKS 3 and heat treated SKS have 23.2 HRC 9.6 HRC and 38.03 HRC, respectively. Tensile test produced yield strength of 452.9 MPa for SUS 304 and 432.6 MPa for SKS 3. Impact energy absorbed during Charpy test for SUS 304 equal to 0,804 J/ mm2 and specimen SKS 3 equal to 0,863 J/mm2. By taking the mechanical test result and SolidWorks simulation, it was concluded that the suitable material for ejector pin is SUS 304.

Abstract:

This paper discloses the development and synthesis of polymer blended nanocomposites filled with nanoclay. The hybridization of epoxy is mixed with vinylester resin (VER) to prepare polymer blend filled with organoclay was studied to enhance mechanical properties of epoxy/VER. Clay loading was done in such a way that with different wt. proportions viz.1, 1.5, 2.0, 2.5, 3.0, 4.0, 5.0, & 7.5 w % ratios. Appropriately cured samples gave excellent mechanical and tribological properties. Results showed that the tensile strength of the composites increased with increase in filler content for the range of filler contents (2.5-4 % vol.). The results indicated that at 4 % wt. of filler concentration the tensile strength obtained is good i.e. 47.79 MPa with density 1.37 gm/cm3 and hardness 45.5. Dry Sliding wear tests were also conducted by following a well-planned experimental schedule based on Taguchi’s design of experiments, considering parameters like Filler content, Normal load, Sliding Velocity and Sliding distance, on a Pin-On-Disc set-up (ASTM G-99 standard, Make: DUCOM Engineers, Bangalore, India). In the experimentation composite pins were worn against a rotating steel disc (Europe Norm) EN-31, (Rockwell C Hardness) HRC 60 and (Roughness Average) Ra 0.02 microns. Control factors like Filler Content, Normal Load were found to be significant factors affecting the Wear rate i.e. the inclusion of nanoclay as filler found to be contributed in improving the wear resistance of the composite. SEM observations are made to probe the wear mechanisms involved.

Abstract:

The aim of this study is to explore the effects of Manganese addition and homogenization treatment on the microstructures and mechanical properties of the Al–7Mg–0.15Ti (B535.0) alloy. The optical microscopy, electrical conductivity measurements, transmission electron microscopy, scanning electron microscopy (SEM + EBSD), as well as Rockwell hardness and tensile tests, were exploited for this purpose. The main objectives are to refine the grain size, inhibit grain growth in the annealed state, and enhance the mechanical strength of the alloy. The results show that the addition of manganese to the Al–7Mg–0.15Ti alloys refined the as-cast and recrystallized grains of the alloys. During the homogenization process, Al4Mn high-temperature stable dispersoids were precipitated in the aluminum matrix. After annealing, the Al4Mn particles blocked the movement of grain boundaries during the growth of the recrystallized grains and inhibited grain growth. Consequently, the annealed alloys showed grain refinement and dispersion strengthening. The Al4Mn dispersoids of the alloys with manganese added were smaller and denser after a two-stage homogenization process compared to those that underwent a one-stage homogenization process. By contrast, for the alloys without the addition of manganese, the recrystallized grains showed normal growth after annealing, and different homogenization processes had no significantly different effects.

Abstract:

Relevance. The most popular cucumber in Russia is pickling type (lenght 10-12 cm). There are not a lot of varieties this type cucumber for high wire and LIT crop in Russian seeds market.Methods. Were tested russian varieties F1 Ciborg, F1 Bavarets (Gavrish company) in compare F1 Bjorn (Enza Zaden, Netherlands) – the most popular in Russia now. Russian customer prefer pickling type because of traditional Russian cuisine. Prices of pickling type cucumber at autumn-winter time in 1-1.5 times more than middle size type cucumber. We had artificial light 240 Wt/sq.m, sodium lamps, our substrate was rockwool – Belagro (company from Belarusian republic). This rockwool have normal quality for short crop (3-4 month for growing cucumber), our plant density 2.76 plant/sq.m it was optimal for our light conditions (natural light in our region and artificial light).Results. Fourteen days after we put plants on slabs we had problems with plants of both russian varieties (F1 Ciborg and F1 Bavarets). We saw yellow parts in leaves, decrease length of stems, lost flowers. We made a decision about too high level of artificial light. We had only one opportunity for decrease it switch off 50% of lamps. We made it and we had 120 Wt/sq.m that. Therefore, we spent 50% less electricity for russian varieties. We think varieties F1 Ciborg and F1 Bavarets not very good for winter crop and we had good results because in our situation we have winter-spring crop, and every day the part of artificial light decrease and the part of natural light increase. F1 Ciborg had a problem with CGMMV and was deleted in 24th week of 2020. But we suppose it depend from a lot of conditions: quality of labor, protection plants. We think it is necessary more additional research. Total yield (for ten weeks of harvesting in winter-spring crop) F1 Bavarets – 32.4 kg/sq.m., F1 Ciborg – 31.9 kg/sq.m more then had F1 Bjorn – 28.9 kg/sq.m. The best marketable condition was F1 Ciborg, the second F1 Bjorn.

Abstract:

The goal of this research was to investigate the effect of electrical conductivity (EC) levels of the nutrient solution on the fresh weight, chlorophyll, and nitrate content of hydroponic-system-grown lettuce. The selected cultivars are the most representative commercial varieties grown for European markets. Seven cultivars (‘Sintia,’ ‘Limeira,’ ‘Corentine,’ ‘Cencibel,’ ‘Kiber,’ ‘Attiraï,’ and ‘Rouxaï’) of three Lactuca sativa L. types’ (butterhead, loose leaf, and oak leaf) were grown in a phytotron in rockwool, meanwhile the EC level of the nutrient solutions were different: normal (<1.3 dS/m) and high (10 dS/m). The plants in the saline condition had a lower yield but elevated chlorophyll content and nitrate level, although the ‘Limeira’ and ‘Cencibel’ cultivars had reduced nitrate levels. The results and the special characteristic of the lollo-type cultivars showed that the nitrate level could be very different due to salinity (‘Limeira’ had the lowest (684 µg/g fresh weight (FW)) and ‘Cencibel’ had the highest (4396 µg/g FW)). There was a moderately strong negative correlation (−0.542) in the reverse ratio among the chlorophyll and nitrate contents in plants treated with a normal EC value, while this relationship was not shown in the saline condition. Under the saline condition, cultivars acted differently, and all examined cultivars stayed under the permitted total nitrate level (5000 µg/g FW).

Abstract:

ABSTRACT In December 1978, the Esso Bernicia spilled 8,000 barrels of Bunker C oil during a berthing accident near the Sullom Voe Oil Terminal. About 100 miles of shoreline were oiled, much of that span heavily. Sullom Voe is a bay of the Shetland Islands, north of Scotland, an area environmentally similar to Prince William Sound. The highly indented, rocky shoreline is inhabited by typical intertidal communities characterized by fucoid algae (rockweed), barnacles, and snails. Biological survey data for the intertidal communities had been collected for three years prior to the spill. During the cleanup, most of the shores that were accessible to heavy equipment were stripped of oily rock, cobble, and gravel. Other fairly accessible areas were hand-cleaned. Dispersants were tried on a few shores, but were ineffective. Many of the less accessible locations were not cleaned at all. The oiled shorelines were resurveyed every year from 1979 through 1987, except 1982 and 1983. Except for the mechanically cleaned areas, the biological communities in the rocky intertidal zone returned to very near normal within the first year, and have remained so in spite of the presence of traces of weathered oil. Normal populations of snails and small crustaceans have thrived in intimate contact with asphaltic residues that remain in some locations. In contrast, the biological communities at the sites that were cleaned mechanically were obliterated, and still had not fully recovered after almost nine years.

Abstract:

ABSTRACT A new landslide-created shoreline in Prince William Sound offered an opportunity to monitor colonization of virgin rock and to compare that colonization with that of nearby oiled and cleaned sites monitored during the early 1990'S. The intertidal zone of six well-separated vertical landslide surfaces were photographed annually from 2001 to 2007 and the photos used to estimate changes in cover of conspicuous intertidal seaweeds. Colonization by rockweed (Fucus sp.) was rapid and by 2003 appeared to converge with density comparable to adjacent undisturbed (control) shoreline. Percent cover of Fucus declined in 2005, then increase again in 2006 and 2007. This pattern of evolving zonation, and rapid increase and then decrease in Fucus cover, was nearly identical to the patterns observed at oiled and cleaned sites in the early 1990'S suggesting that what was seen then was an entirely normal process of intertidal colonization. Additional monitoring would be useful to determine (1) the development of the supra-littoral black lichen (Verrucaria) zone and (2) if variation in the cover, patchiness and zonation at the landslide sites parallels the longterm variation at reference sites.
