A Transcendental To Changing Metal Powder Characteristics, Mahendra Kumar Trivedi Oct 2008

A Transcendental To Changing Metal Powder Characteristics, Mahendra Kumar Trivedi

Mahendra Kumar Trivedi

It’s not often that Metal Powder Report departs from the path of hard facts into the somewhat ‘mushier’ area of metaphysics, but opportunities crop up. While recognising that science has its fair share of charlatans, one such opportunity was presented by a paper submitted by an Indian researcher in which he details work aimed at probing the effects on powder samples where changes were apparently generated by thought. Some will laugh, others will cry, but perhaps among our readers there are those who might be able to help elucidate further the phenomena described…

Effect Of Different Levels Of N, P And K On Downy Mildew (Peronospora Plantaginis) And Seed Yield Of Isabgol (Plantago Ovata), Kunal Mandal, R. Saravanan, S. Maiti Jan 2008

Effect Of Different Levels Of N, P And K On Downy Mildew (Peronospora Plantaginis) And Seed Yield Of Isabgol (Plantago Ovata), Kunal Mandal, R. Saravanan, S. Maiti

Kunal Mandal

The study showed that application of different doses of inorganic nutrients had considerable influence on growth, yield and downy mildew interaction in isabgol (Plantago ovata). It included three levels of nitrogen (0, 30, 60 kg N ha–1), two levels of phosphorous (0, 30 kg P ha–1) and two levels of potash (0, 40 kg K ha–1) for 2 consecutive years. The highest N supply (60 kg ha–1) caused more than 65% increase in disease severity compared with the control. However, application of 40 kg K ha–1 reduced percent disease index (PDI) by more than 10% compared with 0 kg K …

Antidumping Duties In The Agriculture Sector: Trade Restricting Or Trade Deflecting?, Nisha Malhotra, Horatiu Rus, Shinan Kassam Jan 2008

Antidumping Duties In The Agriculture Sector: Trade Restricting Or Trade Deflecting?, Nisha Malhotra, Horatiu Rus, Shinan Kassam

Nisha Malhotra

In this paper we analyze whether U.S. Anti-Dumping (AD) duties in the agricultural sector are effective in restricting trade. More specifically, does imposition of an antidumping duty restrict imports of the named commodity or is there a diversion in the supply of imports from countries named in the petition to countries not named in the antidumping petition? We find that AD duties have had a significant impact on the imports of agricultural commodities from the countries named in the petition. However, our results also indicate that, unlike the manufacturing sector in the US, there was little trade diversion towards countries …

Frontline Demonstration On Sesame In West Bengal, Ganesh Chandra, R L. Sagar Apr 2004

Frontline Demonstration On Sesame In West Bengal, Ganesh Chandra, R L. Sagar

Ganesh Chandra

Sesame is one of the important oilseeds crop in India, which plays a major role in supplementing the income of small and marginal farmers of Sunderbans. One of the major constraints of traditional Sesame farming is low productivity of local varieties. To replace this anomaly, Krishi Vigyan Kendra of CIFRI has conducted frontline demonstration at adopted farmers’ field in four development blocks viz. Kakdwip, Namkhana, Patharpratima and Kulpi of Sunderbans, West Bengal. Cultivation of high yielding varieties of Sesame viz. Rama (Improved Selection-5) and Tilottma (B-67) shows percentage increase of 46.58 and 35.86 respectively over local check. The technology gap …

Container Substrate Temperatures Affect Mineralization Of Composts, Helen T. Kraus, Robert Mikkelsen, Stuart L. Warren Jan 2000

Container Substrate Temperatures Affect Mineralization Of Composts, Helen T. Kraus, Robert Mikkelsen, Stuart L. Warren

Robert Mikkelsen

Traditional N mineralization studies have been conducted by soil scientists using soils and temperatures found in field production. As temperature, in part, governs the rate of mineralization, and container substrates reach much higher temperatures than do soils, the effect of these elevated temperatures on mineralization must be considered to begin to understand N mineralization in container substrates during production. The N mineralization patterns of three composts [turkey (Meleagris gallopavo) litter, yard waste, and municipal waste] were determined under three temperature regimes (45, 25, and 45/25 °C). More organic N was mineralized from composted turkey litter (CTL) than from municipal or …

Soil Treatment For Restoration Projects, David A. Bainbridge Jan 1999

Soil Treatment For Restoration Projects, David A. Bainbridge

David A Bainbridge

Soil treatment is a critical step in restoration projects. When soil problems are ignored restoration projects fail. Erosion, compaction, limited infiltration and other problems can make a site very different from its historic function and structure. Treatment can be done with equipment or by hand and will greatly improve chances for success.

A Comparison Of Three Methods For Determining Root-Knot Nematode Infection Of Cotton Roots, Robert G. Mcbride, Robert Mikkelsen Jan 1999

A Comparison Of Three Methods For Determining Root-Knot Nematode Infection Of Cotton Roots, Robert G. Mcbride, Robert Mikkelsen

Robert Mikkelsen

Three methods for determining the extent of infection of cotton roots (Gossypium hirsutum L.) by root-knot nematode, Meloidogyne incognita (Kofoid and White) Chitwood, were compared. Root-knot nematode eggs were added to pots containing either sterilized soil or soil amended with rye, and cotton seedlings were planted. Cotton root systems were then assessed for infection/damage after 14 and 28 days of exposure. At the 14-day sampling, the roots were stained, using the lactophenol acid fuchsin method and the juvenile nematodes counted. At the 28-day samplings, the cotton roots were given a visual rating for nematode-induced root galling (0-100), and the galls …

Bird Aversive Properties Of Methyl Anthranilate, Yucca, Xanthoxylum, And Their Mixtures, Larry Clark, Bruce Bryant, Igor Mezine Jan 1996

Bird Aversive Properties Of Methyl Anthranilate, Yucca, Xanthoxylum, And Their Mixtures, Larry Clark, Bruce Bryant, Igor Mezine

Larry Clark

We tested the bird aversive properties of methyl anthranilate, yucca extracts, and Xanthoxylum spp. extracts in one- and two-bottle drinking assays that used European starlings (Sturnus vulgaris). In one- and two-bottle tests, methyl anthranilate proved to be the more potent stimulus in producing an avoidance response. Starlings avoided consuming Xanthoxylum and yucca only in the two-bottle tests. Previous studies showed that yucca was a good adjuvant in stabilizing lipophilic compounds in water. Starlings did not avoid binary mixtures of methyl anthranilate and yucca differently from what would be expected if they were only responding to the solution's methyl anthranilate content. …

Grazing Repellency Of Methyl Anthranilate To Snow Geese Is Enhanced By A Visual Cue, J. Russell Mason, Larry Clark Jan 1996

Grazing Repellency Of Methyl Anthranilate To Snow Geese Is Enhanced By A Visual Cue, J. Russell Mason, Larry Clark

Larry Clark

Methyl anthranilate (Rejex-It AG-36) is formulated as a commercial goose repellent. Frequent reapplications of this product are often necessary, and the cost/application is high ($300.00/ha). The present experiment tested the possibility that the repellency of methyl anthranilate might be enhanced by the addition of visual cues. Twelve 0.4 ha plots were assigned randomly to three treatment groups. Plots in the first group (n = 4) were sprayed with 10% Vapor Guard (an agrochemical adhesive). Plots in the second group (n = 4) were treated with a mixture of methyl anthranilate (3.4 kg/ha) and Vapor Guard. Plots in the third group …

Avoidance Of Cabbage Fields By Snow Geese, J. Russell Mason, Larry Clark Jan 1996

Avoidance Of Cabbage Fields By Snow Geese, J. Russell Mason, Larry Clark

Larry Clark

now Goose activity levels were significantly less in cabbage fields than in control fields. Although the data do not unambiguously address the issue of sulfur repellency, we believe that the activity difference is consistent with avoidance of the former and not preference for the latter. Sulfurous volatiles were readily apparent to us during our visits to cabbage fields throughout the study period. Similar odors were not detected in control fields. If sulfurous volatiles were important, then avoidance could reflect some characteristic of the cover crop (e.g., unpalatability acquired through the absorption and translocation of degra­ dation products) or it could …

Degradation Studies Of The Non-Lethal Bird Repellent, Methyl Anthranilate, Eugeny Aronov, Larry Clark Jan 1996

Degradation Studies Of The Non-Lethal Bird Repellent, Methyl Anthranilate, Eugeny Aronov, Larry Clark

Larry Clark

Methyl anthranilate (MA), a food grade flavor and fragrance additive, has been reported to be an effective non-lethal bird repellent in a variety of situations. Despite the experimental success of MA, field studies have yielded widely differing levels of efficacy. Diminished efficacy in some field trials prob­ ably results from the failure of specific formulations to retain or protect the active ingredient under natural conditions. Therefore, a clearer understanding of the physical and chemical factors affecting the stability of MA is needed. We undertook a series of laboratory studies on hydrolysis, photolysis and microbial degradation of MA, the results of …

Swine Waste Disposal Dilemma, Robert Mikkelsen Jan 1995

Swine Waste Disposal Dilemma, Robert Mikkelsen

Robert Mikkelsen

The swine industry has grown rapidly in North Carolina in the past decade, with the majority of the growth occurring in a few counties in the Coastal Plain region of the state. With this expansion has come the problem of swine waste disposal. Mr. Blevins, a local farmer in this region, has been raising swine since 1985. The swine waste on his farm is collected in an anaerobic lagoon and then irrigated onto a bermudagrass (Cynodon dactylon(L.) Pers.) pasture where cattle are fed using intensive rotational grazing techniques. A study of Mr. Blevins' farm revealed very high nitrate concentrations in …

Evaluation Of Plastic And Mylar Flagging As Repellents For Snow Geese (Chen Caerulescens), J. Russell Mason, Larry Clark Jan 1994

Evaluation Of Plastic And Mylar Flagging As Repellents For Snow Geese (Chen Caerulescens), J. Russell Mason, Larry Clark

Larry Clark

The effectiveness of white flags, black flags and Mylar streamers as visual repellents to snow geese (Chen caerulescens) was evaluated. Five farms in Cumberland and Salem counties, New Jersey served as test sites. At each farm, four 10.12 ha fields were selected randomly, and then assigned to four treatment conditions: (a) white plastic flags (one flag per 0.4 ha); (b) black plastic flags (one flag per 0.4 ha), (c) Mylar streamers (one streamer per 0.4 ha); and (d) stakes only (one stake per 0.4 ha). From 2 December 1992 to 24 March 1993, vegetation samples and goose droppings were collected …

Use Of Activated Charcoal And Other Particulate Substances As Feed Additives To Suppress Bird Feeding, J. Russell Mason, Larry Clark Jan 1994

Use Of Activated Charcoal And Other Particulate Substances As Feed Additives To Suppress Bird Feeding, J. Russell Mason, Larry Clark

Larry Clark

Osmotic strength is a function of particle number. The experiments described here were designed to test whether the consumption of a large number of small particles might induce strong osmotic effects that, in turn, could induce food avoidance learning. The experiments also evaluated whether the abrasiveness of fine particulates or their ability to act as organic adsorbants could mediate or contribute to the avoidance of adulterated diets. In experiment I. captive European starlings (Sturnus vulgaris) were given two-cup tests between plain chow and chow adulterated with activated charcoal or Anjan-activaid. a product containing large amounts of activated charcoal. Both adulterants …

Tests And Refinements Of A General Structure-Activity Model For Avian Repellents, Larry Clark, Pankaj Shah Jan 1994

Tests And Refinements Of A General Structure-Activity Model For Avian Repellents, Larry Clark, Pankaj Shah

Larry Clark

We tested the robustness of a structure-activity model for avian trigeminal chemoirritants. Fourteen benzoates and acetophenones were tested using European starlings Sturn us vulgaris as a bioassay. In general. the pre­ viously proposed model was a reasonable predictor of repellency (i.e., irritant potency). We found that the presence of a phenyl ring was critical to repel­ lency. Basicity of the molecule is the next most critical feature influencing repellency. The presence of an acidic function within the electron-withdrawing functionality seriously detracts from repellency. The presence or absence of an electron-withdrawing or -donating group may potentiate repellent effects, but its presence …

Using Hydrophilic Polymers To Control Nutrient Release, Robert Mikkelsen Jan 1994

Using Hydrophilic Polymers To Control Nutrient Release, Robert Mikkelsen

Robert Mikkelsen

Using diverse technological approaches, many types of delivery devices have been used to supply plant nutrients at a controlled rate in the soil. One new approach is the use of hydrophilic polymers as carriers of plant nutrients. These polymers may be generally classified as 1) natural polymers derived from polysaccharides, 2) semi-synthetic polymers (primarily cellulose derivatives), and 3) synthetic polymers. By controlling the reaction conditions when forming the polymers, various degrees of cross-linking, anionic charge, and cationic charge can be added, thereby changing their effectiveness as fertilizer carriers. When fertilizer-containing solutions are mixed with hydrophilic polymers to form a "gel" …

Acute Toxicity Of The Bird Repellent, Methyl Anthranilate, To Fry Of Salmo Salar, Oncorhynus Mykiss, Ictalurus Punctatus And Lepomis Macrochirus, Larry Clark, John Cummings, Steven Bird, Eugeny Aronov Jan 1993

Acute Toxicity Of The Bird Repellent, Methyl Anthranilate, To Fry Of Salmo Salar, Oncorhynus Mykiss, Ictalurus Punctatus And Lepomis Macrochirus, Larry Clark, John Cummings, Steven Bird, Eugeny Aronov

Larry Clark

Several laboratory and field studies have shown methyl anthranilate to be an effective, non-toxic and non-lethal bird repellent, with application potential for protecting crops, seeds, turf and fish stocks from bird damage. Furthermore, methyl anthranilate can be added to liquids for the purposes of protecting nigratory birds, e.g. addition to waste water associated with mining and to standing water pools at airports. Mammalian toxicity data are favorable. Methyl anthranilate is used as a fragrance and food flavoring and is GRAS listed by the US Food and Drug Administration. Despite the favorable outlook for methyl anthranilate's use as a safe repellent, …
