Free Air Velocity

Model EHH-401 resistance to airflow (pressure drop) varies depending on louver application (air intake or air exhaust). Free area velocities (shown) are higher than average velocity through the overall louver size. See louver selection information.

The AMCA Water Penetration Test provides a method for comparing various louver models and designs as to their efficiency in resisting the penetration of rainfall under specific laboratory test conditions. The beginning point of water penetration is defined as that velocity where the water penetration curve projects through 0.01 oz. of water (penetration) per sq. ft. of louver free area. *The beginning point of water penetration for Model EHH-401 is above 1250 fpm free area velocity. These performance ratings do not guarantee a louver to be weather-proof or stormproof and should be used in combination with other factors including good engineering judgement in selecting louvers.

...[pic] |Source: |USDA/Agricultural Research Service | |Date: |January 3, 2007 | Berry Compound Thwarts Enzyme Linked To Cancer  Science Daily — Recent research by Agricultural Research Service (ARS) scientists and cooperators has fortified the standing of pterostilbene (pronounced "tare-o-STILL-bean") for its health benefits, a compound found in berries such as blueberries and grapes, as a cancer inhibitor.  During tests employing cell fragments from mice livers, ARS chemist Agnes Rimando and colleagues in Poland found that the compound strongly suppresses a type of an enzyme that activates cancer-causing processes.  Rimando and her collaborators targeted an enzyme called cytochrome P450, which sets off a variety of compounds--known as "procarcinogens--that can turn substances such as cigarette smoke and pesticides into cancer-causing agents.  Rimando has led numerous animal studies that focused on pterostilbene and its potential benefits to human health. This includes work showing that pterostilbene can help lower cholesterol and prevent heart disease, and that the compound is present in a genus of shrubs that includes many types of berries, including blueberries.  She also led studies that found that the compound is a powerful antioxidant that shows cancer-fighting properties similar to those of resveratrol. Indeed, pterostilbene is a derivative of resveratrol, a compound found in large quantities in the skins...

Wendell Berry - the Hurt Man

...The Hurt Man Life is full of loss and you cannot avoid experiencing it and well as sorrow. As people grow up they come to realize that the world is not as it seemed to be when they were younger. They get more independent and their perspective of life changes. They will have to realize that they are not going to live forever. In the short story The Hurt Man, written by Wendell Berry and published in 2003, we meet Mat who learns all of this. During the short story Mat is growing up. He is born unexpected but he is still very much appreciated. His parents watch him closely so he does not get hurt but this change as he becomes older. At the age of five, the household gets busier and Mat is now more independent. “[...] he was curious and active, when he would be out of their sight. He would stray off to where something was happening, to the farm buildings behind the house, to the blacksmith shop, to one of the saloons, to wherever the other boys were.” (ll. 31-34) This is a perfect example of a child’s natural and healthy development. In line with them getting older their curiosity and independence increase. They do more and more stuff on their own without their parents supervision. It can be extremely difficult for the parents to let go of their children but the importance of it is huge. The difficulty comes, amongst other things, with the world being filled with danger and threats. Mat’s mother, Nancy, is doing a good job even though she has experienced a mother’s worst...

Renewing Husbandry Wendell Berry Summary

...In “Renewing Husbandry,” Wendell Berry argues against the industrialization of farming. He begins by explaining that it began with the invention of the tractor; when his farm first utilized the tractor he resented the mule plow that his father used. He saw the mule team as slow and ineffective, however, later he recognized their value in their slow caring pace of working the land, which he labels “husbandry.” He then claims that the economic growth of society has devalued farming and forced small farms to diminish while large farms flourish. He views that this shift of economic power creates a harmful blow to the quality of farming, he blames mechanization for the destruction of small farms. This ridicule of industrialized farming fails to understand that the renewal of husbandry begins with the individual. Berry believes that the mechanization of farming creates separation between the farmer and the land. Berry states, “Once one’s farm and one’s thoughts have been sufficiently mechanized, industrial agriculture’s focus on production, as opposed to...

...Workshop #4 Berry, Berry Ambitious MBA 454 Marketing Strategies BSA 529 June 13, 2011 Dr. Ehsan Salek Berry, Berry Ambitious Frozen yogurt is hot again, but with a more gourmet tone. Chains, including Pinkberry and Red Mango, are battling in L.A. and looking to expand. The story of Pinkberry’s success is really about the chain's image as a design brand. The fro-yo shops position themselves as coffeehouses, a place to experience frozen yogurt in an inviting atmosphere and linger a while. The frozen yogurt of the 1980s tapped into the fitness craze, a low fat yet still sweet substitute for ice cream. Pinkberry Korean-style yogurt comes in two flavors: plain and green tea. It is rather like Greek yogurt with a hint of lemon. The fresh, tangy, strangely satisfying flavor grows on you. With only two products, minimum staff training, a playfully modern store design and regular customers, Pinkberry franchises seem to be licenses to print money. The snack, with only 25 calories a portion, served with fresh fruit or crunchy toppings like Oreo cookies or Cap’n Crunch. Pinkberry yogurt is one of those American franchise ideas (think soup, coffee, and juice bars) that seem so obvious, you want to kick yourself for not having bought in at the beginning. The growth of the franchise has been explosive, from one Los Angeles store in January 2005 to 16 today, plus three in New York (five more by the end of summer) and, soon, six in London. It has...

...hours. Multiplying 1500 by (12) for a twelve hour processing day, then 18,000 is derived. Bins 1-16 hold 4000 bbl at a time, and bins 17-27 hold 2950 bbl at a time. There are 5 Kiwanee Dumpers (trucks) and each can ship 75 bbl of berries per delivery. Bins 1-16 hold 250 bbl each, so it takes about 3.33 dumps of a truck to fill one storage bin to capacity. 5 trucks at 75 bbl per trip (375 bbl) could fill bins 1-16 (capacity 4000 bbl per hour) in approximately 10.6 trips. 4. The possible capital investments considered by NCC are buying new equipment to reduce the time that drivers wait to unload picked berries. a. The fifth Kwanee Dumper cost $200,000. This acquisition increased loading capacity, yet accrued further overtime costs for drivers because of a lack of processing capabilities and waiting time to dump these loads. b. Another possible capital investment was $40,000 for a light meter system for color grading. No. 3 (premium) berries were bought for $1.50 bbl in 1995. Out of the 450,000 bbls. Of berries, only half were found to actually be No. 3’s. The benefits of this capital is great. c.

Half of the 450,000 bbls of cranberries labeled as No. 3 turned out to be No.2, each one costing $1.5 for a total overpayment of $337,500.

With a savings of $337,500 per year, the return on investment in the light meter system would be 5.1 (337,500 / $66,000). 2. Purchase one additional dryer to increase process capacity by almost 33%. The dryer can be purchased for $60,000. Process capacity would increase to 800 bbls/hr, because each dryer rates 200bbls/hr. As the wet berry flow rate increases to 800 bbls/hr, the bottleneck is still on the dryers because (1125-800=325bbls) are still left unprocessed and the separators can still process 800+375=1175bbls from 1200bbls/hr. However, the resulting flow rate increase of around 33% could cut overtime labor during the fall by as much as $72,000 (12,000 over time hours x $6/hr) each year. The return on investment would therefore be positive at 0.2 ($72,000-$60,000 / $60,000). However, if we are to buy 2 dryers, the dryer capacity increases to 1,000bbls/hr, but another bottleneck will occur at the separator stage it cannot process 375dryberries + 1000wet berries/hr. Thus, it is ideal to buy just one more dryer. 3. Dry holding bins should be converted to wet-dry combination...

...no. 1 (RP 1) faced by National Cranberry Cooperative during the cranberry harvesting period, viz. 1) too much waiting period for trucks before they unload berries at the RP1 and 2) too much overtime costs. There is also a secondary problem regarding grading of process berries. Half of the berries graded top quality are actually not top quality and do not deserve extra premiums paid on the top quality berries. 2.) Process Analysis We start by making a process flow diagram for the flow of berries at RP1 from the moment berries arrive at the RP1 in trucks to the moment they leave in RP1 after being bag packed, bulk loaded into trucks or loaded into bulk tins. The capacities of the various processes are based on the assumptions or data as shown below: Dumping Capacity Number of Kiwanee Dumpers = 5 Average time taken by truck to load the berries onto Kiwanee Dumpers = 7.5 minutes (Maximum being 10 and minimum being 5 minutes) Average weight of berries in a truck = 75 bbls. Dumping Capacity = 5 * 75 * 60 / 7.5 = 3000 bbls/hr. Holding Bin Capacities Bin No. 1-16 can hold dry berries only up to 250 bbls per bin. Total capacity of bin numbered 1-16 = 250*16 = 4000 bbls Bin No. 17-24 can hold dry/wet berries up to 250 bbls per bin Total capacity of bin numbered 17-24 = 250*8 = 2000 bbls. Bin No. 25-27 can hold wet berries up to 400 bbls per bin Total capacity of bin numbered 25-27 = 400*3 = 1200 bbls. De-stoning Capacity No. of de-stoning units = 3 Capacity of each unit...

National Cranberry Cooperative Case Study

...receiving plant no. 1 (RP1), trucks would arrive randomly throughout the day, with a random amount of berries, anywhere from 20 to 400 bbls. In order to utilize transport vehicles more effectively, there should be crews scheduled differently on peak days. It only takes 5 to 10 minutes to unload a truck into a Kiwanne dumper, but the backup would occur when the holding bins were full, causing drivers to have waits up to 3 hours. The backup is not occurring in receiving, so now additional crews are necessary at that station. All feed conveyors are in use during peak times so no new crews need to be added there. However, there seems to be a backup occurring in the bagging station. Instead of keeping the fourth bagging machine as a spare, they should add another five-member team to operate the fourth bagging machine during peak hours. This would result in an additional 2,667 bbls per 12-hour period, or a total of 10,667 bbls per 12-hour period. The additional crews and adding of a bagging station would reduce the number of berries that need to be in holding, and cut down on wait time for the transport trucks. Calculations: 8,000 bbls/3 bagging machines = 2,667 bbls per machine per 12-hour period 4 bagging machines times 2,667 bbls per machine = 10,667 bbls per 12-hour period 10,667 bbls per 12- hour period means 21,333 bbls per 24-hour period 2. Would the installation of a berry grader positively impact the farmers’...

...long-term achievable throughput rate. Because wet and dry berries follow different routes at RP#1 there will be a maximum achievable throughput for each. The capacity of the dryers is the bottleneck for the wet berries. The maximum throughput for wet berries is 600 bbls/hr. For dry berries the separation process is the bottleneck. The maximum throughput for dry berries is 1200 bbls/hr. The percentage of wet berries to dry berries would affect the throughput rate. Given the current proportion of berries received the capacity of the dryers would be the maximum throughput of the system. The dryers are the system bottleneck. And as the trend of water harvesting continues, this situation worsens. All the process/resources at RP#1 contribute to the throughput but the limitation is the bottleneck. 3. The trucks wait because the processing capacity is less than the system input. And the temporary holding bins are inadequate to buffer the berries coming in and the plants processing capacity. But by using the Theory of Constraints to identify the system bottle necks we are able to discover the root cause of the waits. The large back log of berries is caused by several factors The plant is not currently equipped to handle the supply of wet berries. This problem has likely been increasing over the years as more cranberries are being wet-harvested. This problem is evident in the lack of web berry temporary storage and inadequate berry drying capacity. These bottlenecks are slowing the...

National Cranberry Cooperative Case Study

...buy some new equipment. NCC’s overtime costs were out of control and the growers were upset that their trucks and drivers had to spend so much time waiting to unload process fruit into the receiving plant. Will Walliston, the superintendent, thought that the way to avoid these problems was to increase their capacity by buying new equipment. However, in order to buy new equipment it was very important to move quickly since the purchasing and installation lead times are in excess of six months. Another possible capital investment considered was the installation of a light meter system for color grading. Using color pictures as a guide, the truckload of berries were graded according to color and classified as Nos. 1, 2A, 2B or 3, from poorest color (No. 1) to best (No.3). There was a premium of $1.50 per bbl. paid for No. 3 berries. Whenever there was any question about whether or not a truckload is No. 2B or...

“Blackberry Eating”, Galway Kinnell

...“Blackberry Eating”, Galway Kinnell In the story “Blackberry Eating”, Galway Kinnell compares the beloved past time of eating berries with his love of expressing language in verbal communication. He uses the sound devices to develop how he enriches his poem to show his love of language and words. He uses alliteration to give meaning and depth to words. Kinnell also uses consonance heavily in this poem to lead the reader through the poem. He uses cacophony to slow down the reader to deliver emphasis on certain words. The title starts off with a cacophonic phrase. “Blackberry Eating” starts off rolling off your tongue with the first word. Then you encounter “Eating”, this word breaks up the flow of the title. This stops the reader and makes them assess the action that is occurring with the berries. In the phrase, “the stalks very prickly, a penalty” you stop and restart. You are led back to prickly with the word penalty. You get the understanding that the thorns are a punishment to the reader for enjoying the forbidden meal derived of the “black art of blackberry-making”. Another example of cacophany is the use of the letter B in the poem. The use of black, blackberries, breakfast provide a bounty of bold words that give a movement to the work that is very melodic. Alliteration is used throughout the poem to create a slippery, smooth progression of the poem. When he says “black blackberries” it describes the richness and ripeness of the fruit. Another example...

Polarica Study Case

...required storage capacity calculation and where to locate this inventory. INTRODUCTION Polarica is a company in northern Sweden. It is worldwide distributor of variety specialty food items. During the lastcouple of years the volume of wild berries, mostly blueberries,has increased a lot. This expansion forces Polarica to consider investments in freezing-in capacity and cold-storage capacity. Industrial Logistics, Lulea University of Technology were engaged to help Polarica to decide if they really needed additional capacity and, if so, where to geographically locate it by conducted a simple heuristic model base on load-distance analysis. With this model, the problem is tackled and solved. Q1: What capacity measure does Polarica used? According to David Barnes (2008) Capacity defined as level of activity or output that can be achieved (by operation, facility or organization) in given period of time under normal working conditions. However capacity needs to related to organization’s ability to supply output in order to meet customer demand. In the same way capacity defined, it is difficult to measure. So do happen to Polarica’s where the storage capacity needs to calculate and to revise the inventory location. Polarica selling wild berries and others specialty goods where the nature of the goods is perishable where inventory control play important role in their operation management. The measures that Polarica’s used in operations are the freezing-in capacity and the total storage...

Driscoll's Case Study

...Our class attended a tour of Driscoll’s Berry in Watsonville on Thursday, October 22. Driscoll’s is a local ag company that distributes the berries that their growers grow. Driscoll’s has nurseries where they grow the plants that they give to their growers to plant and harvest. The plants are the proprietary property of Driscoll’s. After the growers harvest the crops they bring the berries to Driscoll’s coolers where the berries are inspected by graders for quality, and then the berries are chilled to thirty-four degrees in the cooler before being loaded on trucks and sent to customers. Last year Driscoll’s sold over one billion pounds of fruit, filled 150,000 orders, and loaded 38,000 trucks. Driscoll’s is the leading berry provider...

...process and market their berries. In the early 1990’s, there was a growing surplus of berries so the growers resorted to the Agriculture Marketing Agreement Act of 1937 to restrict the amount of crop processed. In addition, the cranberry harvesting process was becoming more automated during this period of time. There are two types of berry harvesting: 1) water harvesting which involves flooding bogs, using machines to shake the bushes, and collecting the berries that float to the top; and 2) dry harvesting which requires hand picking. Water harvesting typically results in a yield of 20% more berries than dry harvesting, however, it causes more damage and reduces the time between harvest and long-term storage. Cranberries are processed for one of two purposes: 1) preparing raw berries for sale; and 2) preparing berries for use in juice, canning, freezing, and other processes. The process for preparing berries to be processed at Receiving Plant 1 (RP1) is as follows: 1) Bulk trucks arrive at random with an average delivery of 75 barrels (bbl: which weighs ~100 pounds). 2) The truck is weighed, the full and empty truck weight is recorded and a sample(s) of 30 pounds is taken for initial berry grading (Lowest grade and price 1, 2A, 2B, 3 Highest grade and price). 3) The truck backs into 1 of 5 dumpers 4) A conveyor belt takes the berries to the second level to one of 27 holding bins (takes 7-8 minutes): 1-24 Holds 250 bbls of wet or dry berries (6,000 bbls total) ...
