Abstract This study aims to evaluate effectiveness of two operational management systems for steer gains and fly control. The first strategy evaluated was pasture burn date of March (MAR) or April (APR). The second management strategy was fly control through feeding free-choice mineral with spices (SPICE) or without spices (CON). Eight pastures (n = 281 steers; initial weight 277.7 ± 25.2 kg) were used in a 2 x 2 factorial treatment structure. Steers were weighed individually, randomly assigned to treatment, and grazed for 85 days. Weekly 33% of steers per pasture were photographed and fly numbers counted. ADG was impacted by both burn date and mineral type (P = 0.01). Cattle on the APR-SPICE treatment had a greater ADG than MAR-SPICE and APR-CON with MAR-CON intermediate. Cattle on SPICE gained 4.5 kg (P = 0.12) more than cattle consuming CON mineral. Flies per steer were impacted by burn x mineral x week (P < 0.001). In general, APR-SPICE steers had a greater number of flies weeks 8, 10, and 11 (P < 0.05), corresponding to a time when mineral intake averaged 72% of the formulated intake. The MAR-SPICE steers consumed on average the formulated amount of mineral and through the entire grazing period had lower number of flies than APR-SPICE steers (P < 0.05). The second largest ADG observed with the MAR-CON treatment may be attributed to lower fly numbers as this treatment had one extra week below economic threshold for horn flies. These results are somewhat inconclusive on pasture burn date, but show that the addition of spices to a free-choice complete mineral shows promise as a cost-effective method to increase gains in stocker steers on tallgrass native range. As a fly control method, the spices utilized in this study may be effective if intake is at formulated level.

Abstract Ivomec® pour-on was evaluated in two studies at two different locations in West Central Nebraska. In study No. 1, Ivomec was applied to 72 yearling steers located at the Gudmundsen Sandhills Laboratory, Whitman, NE. The steers were weighed and the Ivomec was applied at the recommended rate. A second application was made 28 d later, 7 Jul. A group of 44 cows served as an untreated control. In study No. 2, Ivomec pour-on was compared to 1% Co-Ral dust bags (force-use, to obtain water) for horn fly control. This study was located near North Platte, NE, in native range. Ivomec was first applied to 41 heifers 27 May at the recommended rate and subsequent applications were made about every 28 d until the end of the study. Treatment dates were 27 May, 30 June, and 4 Aug. Eighty heifers utilized the 1% Co-Ral dust bags and a group of 10 cows served as an untreated control. Horn fly counts for both studies were recorded at weekly intervals by counting the total number of horn flies on both sides on an animal.

Experiments conducted on a ranch in southern Alberta evaluated the productivity of the cow-calf unit in breeding herds in response to treatment with pesticidal (8% fenvalerate wt/wt) ear tags to control infestations of horn flies, Haematobia irritans (L.). Optimum economic productivity was found to depend on the effectiveness of tags in establishing fly-free grazing (FFG) conditions and maintaining them without interruption during the complete summer grazing period. This was achieved when animals were tagged before the first overwintering horn flies emerged in spring. Present formulations of pesticide in tags will support the required FFG conditions for 85–90 d. Management of herds for maximum gains throughout the summer in southern Alberta requires fly control that will maintain FFG conditions for at least 115 d. Rates of gain in weight of animals under FFG conditions on dry range conformed with the 16% improvement in efficiency of production projected from controlled experiments on irrigated pastures.

Abstract Burning pastures in April has historically been a method to increase stocker gains for summer grazing in Kansas, yet is becoming an issue from smoke management. Finding alternative burning windows along with feed options that maintain a similar gain to April burns is important from producer’s perspective. Therefore, the purpose of this study is to evaluate spices/essential oils and timing of pasture burning on growing steer gains. 281 steers (292 ± 28 kg) were randomly assigned to one of 8 pasture of tallgrass native prairie in a completely randomized design model. The treatment structure was a 2 x 2 factorial where the first factor was pasture burning date at two levels (March and April) and the second factor was free-choice mineral type (control (CON) or spices (SPICE)). Spices include garlic oil and a 4-spice blend (Solus, Wildcat Feeds LLC, Topeka). Steers were weighed at the start and end of 90 d grazing period. Total gain, average daily gain, and final body weight were evaluated. There was no interaction between burning time and mineral type (P > 0.10) for average daily gain, total gain, nor final body weight. Steers on pastures burned in April had a 0.16 kg/d ADG advantage over burning in March which resulted in 14.3 kg more gain over 90 d (P < 0.0001). Steers on SPICE averaged 0.06 kg/d and gained 5 kg more (P = 0.02) than steers on CON mineral. Burning in April results in greater steer gains than March burning and feeding a mineral with spices increase gains, yet these two are not additive. Addition of SPICE mineral may be one method to allow producers to extend burning window and maintain cattle production.

Abstract The conventional gravel pack sand control completion (High Rate Water Pack / Extension Pack) was the primary sand control method for PTTEPI, Myanmar Zawtika field since 2014 for more than 80 wells. Although the completion cost of gravel pack sand control was dramatically reduced around 75 percent due to the operation performance improvement along 5 years, the further cost reduction still mandatory to make the future development phase feasible. In order to tackle the well economy challenge, several alternative sand control completion designs were reviewed with the existing Zawtika subsurface information. The Chemical Sand Consolidation (CSC) or resin which is cost-effective method to control the sand production with injected chemicals is selected to be tested in 3 candidate wells. Therefore, the first trial campaign of CSC was performed with the Coiled Tubing Unit (CTU) in March to May 2019 with positive campaign results. The operation program and lesson learned were captured in this paper for future improvement in term of well candidate selection, operation planning and execution. The three monobore completion wells were treated with the CSC. The results positively showed that the higher sand-free rates can be achieved. The operation steps consist of 1) Perform sand cleanout to existing perforation interval or perforate the new formation interval. 2) Pumping pre-flush chemical to conditioning the formation to accept the resin 3) Pumping resin to coating on formation grain sand 4) Pumping the post-flush chemical to remove an excess resin from sand 5) Shut in the well to wait for resin curing before open back to production. However, throughout the campaign, there were several lessons learned, which will be required for future cost and time optimization. In operational view, the proper candidate selection shall avoid operational difficulties e.g. available rathole. As well, detailed operation plan and job design will result in effective CSC jobs. For instance, the coil tubing packer is suggested for better resin placement in the formation. Moreover, accommodation arrangement (either barge or additional vessel) and logistics management still have room for improvement. These 3 wells are the evidences of the successful applications in Zawtika field. With good planning, lesson learned and further optimization, this CSC method can be beneficial for existing monobore wells, which required sand control and also will be the alternative sand control method for upcoming development phases. This CSC will be able to increase project economic and also unlock the marginal reservoirs those will not justify the higher cost of conventional gravel pack.

Abstract Y-Tex experimental ear tags (YT-615) were compared with PYthon® 10% ear tags for horn fly control on beef cattle. The study was initiated 17 Jun at the West Central Research and Extension Center, North Platte, NE. Cattle used in the trial were randomly selected from a herd of 200 heifers. Ear tags were applied as follows: YT-615 applied to 25 heifers (one tag per heifer), PYthon applied to 30 heifers (two tags per heifer) and PYthon applied to 120 heifers (one tag per heifer). An untreated group of 10 heifers served as a comparison. The three treatment groups were maintained in separate native range pastures throughout the study period. Horn fly counts were recorded at weekly intervals by counting flies on both sides of a minimum of 15 heifers during each fly counting session.

The choice of cost-effective method of anticorrosive protection of steel structures is an urgent and time consuming task, considering the significant number of protection ways, differing from each other in the complex of technological, physical, chemical and economic characteristics. To reduce the complexity of solving this problem, the author proposes a computational tool that can be considered as a subsystem of computer-aided design and used at the stage of variant and detailed design of steel structures. As a criterion of the effectiveness of the anti-corrosion protection method, the cost of the protective coating during the service life is accepted. The analysis of existing methods of steel protection against corrosion is performed, the possibility of their use for the protection of the most common steel structures is established, as well as the estimated period of effective operation of the coating. The developed computational tool makes it possible to choose the best method of protection of steel structures against corrosion, taking into account the operating conditions of the protected structure and the possibility of using a protective coating.

Wastewater Quality

About one hundred and fifty wastewater reservoirs store effluents for irrigation in Israel. Effluent qualities differ according to the inflowing wastewater quality, the degree of pretreatment and the operational parameters. Certain aspects of water quality like concentration of organic matter, suspended solids and chlorophyll are significantly correlated with the water column transparency and colour. Accordingly optical images of the reservoirs obtained from the SPOT satellite demonstrate pronounced differences correlated with the water quality. The analysis of satellite multispectral images is based on a theoretical model. The model calculates, using the radiation transfer equation, the volume reflectance of the water body. Satellite images of 99 reservoirs were analyzed in the chromacity space in order to classify them according to water quality. Principal Component Analysis backed by the theoretical model increases the method sensitivity. Further elaboration of this approach will lead to the establishment of a time and cost effective method for the routine monitoring of these hypertrophic wastewater reservoirs.

Several methods of Deoxyribonucleic acid (DNA) extraction have been applied to extract bacterial DNA. The amount and the quality of the DNA obtained for each one of those methods are variable. The study aimed to evaluate bacterial DNA extraction using conventional boiling method followed by alcohol precipitation. DNA extraction from Gram negative bacilli was extracted and precipitated using boiling method with further precipitation by ethanol. The extraction procedure performed using the boiling method resulted in high DNA yields for both E. coli and K. pneumoniae bacteria in (199.7 and 285.7μg/ml, respectively) which was close to control method (229.3 and 440.3μg/ml). It was concluded that after alcohol precipitation boiling procedure was easy, cost-effective, and applicable for high-yield quality of DNA in Gram-negative bacteria.
