Chipping Away at the Right to Strike

Abstract: On June 1, the Supreme Court issued a significant decision against the labor movement in Glacier Northwest v. Teamsters Local Union No. 174. In an 8–1 split, the Court found that the National Labor Relations Act does not protect striking cement truck drivers from being sued by their employer, who alleges damages for lost cement caused by their work stoppage. The decision, perhaps by design, has received little public outcry.

Wait by Antoinette Portis (review)

Reviewed by: Wait by Antoinette Portis Hope Morrison Portis, Antoinette Wait; written and illus. by Antoinette Portis. Porter/Roaring Brook, 2015 32p ISBN 978-1-59643-921-4 $16.99 R* 3-6 yrs This picture book employing only three words follows a young boy and his mother on a walk through a city. Mother pulls the boy along, looking at her watch and urging “Hurry!”; the boy is distracted by the many fascinating things along the way (a dachshund, a cement truck, an aquarium, etc.) and keeps calling “Wait.” When it starts to rain, the two head for the train platform; just as they are about to board, the pulls his harried mother back to see a double rainbow spread across the urban skyline (“Yes. Wait,” the mother finally agrees). The dichotomy between kid purpose and adult purpose will be a familiar one to adult readers aloud, and the message comes sweetly and subtly through the little boy, who is more present in the moment than his hurried parent. The art, pencil, charcoal, and ink illustrations touched with digital color, incorporates chunky outlines set against white, and on many of the spreads the focus shifts from a wide-angle view of a bustling city street to a tightly focused depiction of the singular object that caught the boy’s eye. Both innovative and joyful, this clever new offering from Portis will charm children and grownups alike with its simple but effective reminder to slow down.

Strength Analysis of Bulk Cement Truck Body Based on NASTRAN

With the rapid development of our nation’s economic construction, bulk cement trucks have developed rapidly among the special vehicles. The entity model of the bulk cement body tank was created using 3D drawing software UG. The model’s accuracy was proved through calculation and on the basis of the entity model the strength of structure was analyzed by Finite Element Analysis software Nastran. Lightweight processing of steel material was made to reduce the overall quality of cement truck and the loading capacity was increased under the condition of meeting the design strength. The theory basis on the development research and optimization design of bulk cement truck tank has been provided.

Blue Hijab

Blue Hijab Myronn Hardy (bio) What becomes of a girl in blue hues? Through a field green where boulders are serrated ready to tumble tear earth exposing the clay of a civilization forced under. This is where we feed. Where sheep sully grass. Where the shepherd sleeps until his flock is fat. The girl gathers vegetables wild parsley. At the market she is accosted by a boy dazzled by her blue hijab. How each thread extends light. That same light crushing over his teeth in a mouth cascading. A cement truck churns on her road home. This is her mind attempting something it hasn’t. Thoughts more like wire tangles tricks in knots traps what shouldn’t be trapped loose paper plastic this is how we are clogged. We are weighed distracted rendered without progress. [End Page 234] How the telephone poles look more like something left from a visit undocumented. A phenomenon unspoken of if only to maintain credibility. Here internal lives are never exposed. Pretending is not optional not here where we build close ourselves in stone. The onions make her cry as a caterpillar crosses the counter of chipped tile. What becomes of a girl in blue hues? Her hijab on the floor the potatoes in the sink soaking the dirt disconnecting assembling itself into something with order a sea floor shifting.

Noise control evaluation for a concrete batch plant.

As a result of neighborhood complaints, an Administrative Consent Order was issued to a concrete batch plant for violating the Massachusetts noise policy. The fact that the batch plant had been in business long before the residential subdivision was built did not factor in the State’s decision. A detailed noise control study was conducted for the facility. All mobile and stationary sources of noise were measured in addition to measurements at the receiving property. The major sources included mixer trucks receiving concrete and prepping their load, concrete trucks climbing a hill, batch plant dust collector fans, and bulk cement truck deliveries. The measurements were analyzed, and a series of noise control measures was evaluated and recommended, some of which were implemented by the facility. Several rounds of controls and associated sound level testing were conducted to determine if the batch plant met the State noise requirements, and compliance was eventually achieved. This paper will discuss the key ...

The Orthography of Provocation, and: Between Two Men, and: All Day I Dream about Sex

The Orthography of Provocation, and: Between Two Men, and: All Day I Dream about Sex Laura McCullough (bio) [Erratum] The Orthography of Provocation I wanted a cement truck in this poem, but didn’t have one, and if I had there wouldn’t have been room for the tree I was trying to grow, the one made of cells which aren’t the smallest unit of meaning or even attention, but a cell will simply have to do. All of us are perturbed and perturbing, the perturbations sometimes lovely as birds lifting from the head of a tree in unison or lovely, yes, let’s admit this, as the rumbling nostrums of that cement truck grinding down the road [End Page 36] past the old, grand trees lining it, the flocks of birds all provoked from their rest. We take flight, too, feeling palliated momentarily, and you take my hand across the membrane of this poem, and, for a minute, I understand the word placebo and am grateful to be stuck in it, rooted once more to the only street on which I’ve ever known how to live. Between Two Men Among the bamboo’s slanting stripes I glimpse The tiger’s stripes and sense the bony frame Under the splendid, quivering cover of skin. I was walking on Nassau Street in Princeton on my way to freshman convocation in the church by the sculpture of fear and forgiveness: two men, one kneeling, hands bound, the other standing with a knife in his hands; what’s between them unknowable, but obvious. I was waiting for the procession to begin. There were African drummers, air socks in the shape of fish, faculty, women and men of worship wearing crosses, stars, symbols, and colorful robes, and then the president, Shirley, bringing up the rear [End Page 37] and six hundred new students, but I was thinking of dead tigers, bright skins confiscated in airports, the wild laid out on linoleum. It was in India, a poaching campaign, and all the reserves were decimated, no tigers left to hunt, beaten to death in their leg traps so as not to mar the hides, cash on the black market, money in pockets, blood on machetes, but none of this new. The sculpture of the two men is black metal. The light catches the concaves and convexes. The students scurried by, their eyes as open as possible, catching all of it: the heel of hand on skin-head drums, the flying fish, their belief in immortality filling the air like incense or blood after a kill. All Day I Dream about Sex That goat. You love that goat more than you love me, more than you love your wife. —Philip K. Dick, Do Androids Dream of Electric Sheep? I’m trying to say something as clearly as I can, like this backronym for Adidas which isn’t an acronym at all, but portmanteau. The owner is Adolf Dassler, nicknamed Adi— you see, Adi Das? Then someone made up: all day I dreamed about sex. That’s funny, but how about all day I dream about soccer, [End Page 38] or socks, or sweatshops, or Sudan? There’s a difference between compression and tension; the former a reduction in volume; the latter the relationship of force between two or more things; how far can you stretch a string before it breaks, or a country, or a teenager who makes sneakers, or the one who’s willing to knock another one down and kick him in the head, so he can steal the shoes off his feet? I wanted to say something clear, and all I had was ears so full of letters and words: k’s, diphthongs, sporks, and cyborgs, trying to neologize the collision of them or find someone to blame for my dumbness. Consilience doesn’t mean sentience, not without a certain self-awareness anyway, more than it requires to tie your shoelaces. Is there a word for it yet—to imagine what’s beyond the break, living on the taut string?

Shirley J. Dreiss (1949–1993)

The hydroscience community recently lost one of its true leaders. In rainy weather on December 14, 1993, Shirley Dreiss lost her life in a collision with a cement truck while driving from Santa Cruz, Calif., to San Francisco Airport.Shirley, 44, was professor and chair of the Department of Earth Sciences at the University of California at Santa Cruz. A superior research scientist and educator, the breadth of her activities and interests were perhaps unnoticed by many because of her modesty and generosity. To those in the field she maintained an international reputation as a hydrogeologist with recognized expertise in diverse topics including arid basin hydrology, quantitative analysis of flow through karst aquifers, moisture and contaminant transport through unsaturated soils, and the hydrogeology of subduction zones.

Peritoneal Dialysis in the Workplace

Pulmonary alveolar proteinosis developed in a 29-year-old white man within 2 years of working as a cement truck driver. Pulmonary alveolar proteinosis (PAP), an uncommon respiratory disorder characterized by the accumulation of phospholipid material within the alveoli, has been described in association with exposure to silica, aluminum oxide, and a variety of dusts and fumes. Although a link between exposure to Portland cement and PAP has not been previously noted, this type of cement contains nearly 20% silica. Lung biopsy material, originally used to diagnose PAP, was reviewed under electron dispersive spectroscopy. Analysis indicated the presence of silica particles within the alveolar fluid and macrophages. A number of items support a causal relationship between exposure to cement dust and PAP: (1) the temporal sequence between assuming job duties and the development of the illness, (2) improvement following removal from further exposure, (3) dusty, unprotected working conditions, (4) the presence of silica within the cement, and (5) the alveolar fluid from periodic acid-Schiff-positive lung tissue.

It Was a DeSoto

THE TITLE OF THIS PIECE is almost arrogant. It a DeSoto? or Maybe It Was a DeSoto would more honestly reflect the content. As I hope to suggest, no matter where in history a motif seems to have developed, research often shows antecedents. And the process of infinite regression carries engrams of doubt that are particularly sharp for the collector of folklore. Quite likely every folklorist has encountered versions of the urban tale of the cement truck dumping its contents into an empty car. This tale is told twice in Jan Brunvand's Study of American Folklore, once in the text itself and once in an appendix to the book by J. Barre Toelken, The Folklore of Academe.' In the Brunvand text it appears in connection with the true story of the man who returned to his car and found a dent in one of the fenders along with the following note under the windshield wiper: The people who are watching think I'm writing my name and address on this note, but I'm not. Brunvand notes that this event has been printed in two newspapers as a local occurrence, then goes on to say:

Plugging Thief Zones in Water Injection Wells

Abstract Standard Oil Co. of California is improving performance of its California water floods by improving vertical coverage and reducing water cycling. This program is being achieved by selectively plugging thief zones in water injection wells with a mixture of silicic acid gel and either gilsonite or silica flour. Previous field trials over a period of 10 years with many other materials and techniques had not achieved the desired results. This article discusses the theory and placement techniques of silicic acid gel and presents the results of successful plugging operations in unsegregated, multilayered reservoirs consisting of interbedded soft shales and unconsolidated sands. The operations have been successfully conducted in slotted liner completions, gravel-packed liner completions and cemented gun- or jet-perforated liner completions. The silicic acid gel is prepared in the field, and the entire operation can be conducted with a production hoist and cement truck. Results of this program show conclusively that silicic acid gel in conjunction with proper placement techniques can be utilized to effectively plug thief intervals in water injection wells. This is expected to become a major factor in improving waterflooding efficiency with a resultant decrease in operating costs and increase in net profit. Introduction The economic success of a waterflood in thick, multilayered sands is dependent upon the efficiency of the displacement process. Control of vertical injection coverage is necessary for the maximum oil recovery and the reduction of excessive water cycling. Effective vertical coverage can be achieved by plugging thief intervals or with subsurface controls. The Vickers zone, Inglewood oil field, Calif., is an Unsegregated, 1,500-ft thick, multilayered reservoir consisting of unconsolidated sands interbedded with soft shales (Fig. 1). The average net sand thickness in this interval is 520 ft. The porosity and permeability values range from 28 to 36 percent and 500 to 2,500 md, respectively. Most injection wells are completed with either gravel-packed or slotted liners. In unsegregated zones this type of completion precludes the use of packers and subsurface beans to control or exclude injection into thief intervals. Within this zone, thief intervals are not confined to particular stratigraphic intervals; therefore, they cannot be excluded upon completion. General Theory: Selective Plugging Selective plugging in injection wells is not new to the petroleum industry. Cement, colloidal clays, inert solids, paraffins, waxes, organic resins and gels have long been utilized. Opinions differ as to the benefits obtained from using a selective plugging technique since apparently only the area adjacent to the wellbore is affected.
