The Wheat Jointworm and Its Control
Revised edition. "The wheat jointworm is a very small grub which lives in stems of wheat, feeding on the juices of the plant and causing a slight swelling or distortion of the stem above the joint. The egg from which it hatches is laid in the stem by an insect resembling a small black ant with wings. This insect attacks wheat only. The injury which it causes to wheat is very distinct from that caused by the Hessian fly, yet the effects caused by these two insects are often confused by farmers." -- p. 1-2. This bulletin gives a brief outline of the life cycle and the nature of the injury to the plant by the jointworm so that any farmer may readily recognize its work and be able to apply the measures of control herein recommended.

Injury Experience in the Coking Industry, 1951
From Introduction and Summary: "Reports from operating companies showed that 25,715 men worked at coke ovens in 1951, about 6 percent more than were employed in 1950 and, except in 1943, the largest work force since 1930, when 28,139 men were employed. The work time for all employees was 70,190,493 man-hours. The returns indicated an average of 344 work days per man as compared with 341 days in the previous year. Accidents at the ovens resulted in the death of 10 and injury to 768 workers, both of these figures representing fewer injuries than in 1950."

Oil and Gas Wells through Workable Coal Beds: Papers and Discussions
From Preface: "In carrying out such a policy with reference to the subject under consideration, the Bureau of Mines invited the State geologists, mine inspectors, and a number of coal operators and oil and gas well drillers from the States interested to meet representatives of the Bureau of Mines in Pittsburgh, Pa., for a discussion of the subject during February 7 and February 8, 1913. This adjourned meeting of the conference will be held at an early date and its report will be printed in a later edition of this bulletin, with such additional suggestions as may be received by the Bureau of Mines. The bureau will be glad, therefore, to receive at the earliest practicable date any additional suggestions or any additional information throwing light on the matters discussed in this bulletin."

Analysis of variation of piston temperature with piston dimensions and undercrown cooling
From Summary: "A theoretical analysis is presented that permits estimation of the changes in piston-temperature distribution induced by variations in the crown thickness, the ring-groove-pad thickness, and the undercrown surface heat-transfer coefficient. The analysis consists of the calculation of operating temperatures at various points in the piston body on the basis of the experimentally determined surface heat-transfer coefficients and boundary-region temperatures, as well as arbitrarily selected surface coefficients."

Carbon Sequestration in Reclaimed Mined Soils of Ohio
This research project is aimed at assessing the soil organic carbon (SOC) sequestration potential of reclaimed minesoils (RMS). The experimental sites, owned and maintained by the American Electrical Power, are located in Guernsey, Morgan, Noble, and Muskingum Counties of Ohio. These sites, characterized by age chronosequences, were reclaimed with and without topsoil application and are under continuous grass or forest cover. During this quarter, bulk and core soil samples were collected from all 13 experimental sites for 0-15 cm, 15-30 cm, and 30-50 cm depths. In addition, 54 experimental plots (4 x 4 m) were established at three separate locations on reclaimed minesites to assess the influence of compost application on SOC during project period 2. This report presents the results from two sites reclaimed during 1978. The first site is under grass and the other under forest cover. The soil bulk density ({rho}{sub b}), SOC, total nitrogen (TN) concentrations and stocks were determined for these two sites on a 20 x 20 m grid. The preliminary analysis showed that the {rho}{sub b} ranged from 0.88 Mg m{sup -3} to 1.16 Mg m{sup -3} for 0-15 cm, 0.91 Mg m{sup -3} to 1.32 Mg m{sup -3} for 15-30 cm, and …

Carbon Sequestration in Reclaimed Mined Soils of Ohio Quarterly Report
This research project is aimed at assessing the soil organic carbon (SOC) sequestration potential of reclaimed minesoils (RMS). The experimental sites, owned and maintained by the American Electrical Power, are located in Guernsey, Morgan, Noble, and Muskingum Counties of Ohio. These sites, characterized by age chronosequences, were reclaimed with and without topsoil application and are under continuous grass or forest cover. During this quarter, water infiltration tests were performed on the soil surface in the experimental sites. Soil samples were analyzed for the soil carbon and nitrogen contents, texture, water stable aggregation, and mean weight and geometric mean diameter of aggregates. This report presents the results from two sites reclaimed during 1978 and managed under grass (Wilds) and forest (Cumberland) cover, respectively. The trees were planted in 1982 in the Cumberland site. The analyses of data on soil bulk density ({rho}{sub b}), SOC and total nitrogen (TN) concentrations and stocks were presented in the third quarter report. This report presents the data on infiltration rates, volume of transport and storage pores, available water capacity (AWC) of soil, particle size distribution, and soil inorganic carbon (SIC) and coal carbon contents. The SIC content ranged from 0.04 to 1.68% in Cumberland tree …

Carbon Sequestration in Reclaimed Mined Soils of Ohio Quarterly Report
This research project is aimed at assessing the soil organic carbon (SOC) sequestration potential of reclaimed mine soils (RMS). Experimental sites characterized by distinct age chronosequences of reclaimed minesoil were identified. These sites are owned by Americal Electrical Power and are located in Guernsey, Morgan, Noble, and Muskingum Counties of Ohio. The sites chosen were: (1) reclaimed without topsoil application (three under forest and three under continuous grass cover), (2) reclaimed with topsoil application (three under forest and three under continuous grass cover) and (3) unmined sites (one under forest and another grass cover). Soil samples were collected from 0 to 15 cm and 15 to 30 cm depths from each of the experimental site under continuous grass and SOC and, total nitrogen (TN) concentration, pH and electrical conductivity (EC) were determined. The results of the study for the quarter (30 September to 31 December, 2003) showed that soil pH was > 5.5 and EC < 4 dS m{sup -1} for all sites and depths and therefore favorable for grass growth. Among the three reclamation treatments, SOC concentration increased from 1.9 g kg{sup -1} for site reclaimed in 2003 (newly reclaimed and at baseline) to 11.64 g kg{sup -1} for …

Carbon Sequestration in Reclaimed Mined Soils of Ohio Quarterly Report
Assessment of soil organic carbon (SOC) sequestration potential of reclaimed minesoils (RMS) is important for preserving environmental quality and increasing agronomic yields. The mechanism of physical SOC sequestration is achieved by encapsulation of SOM in spaces within macro and microaggregates. The experimental sites, owned and maintained by American Electrical Power, were characterized by distinct age chronosequences of reclaimed minesoils and were located in Guernsey, Morgan, Noble, and Muskingum Counties of Ohio. These sites were reclaimed both with and without topsoil application, and were under continuous grass or forest cover. In this report results are presented from the sites reclaimed in 2003 (R03-G), in 1973 (R73-F), in 1969 (R69-G), in 1962 (R62-G and R62-F) and in 1957 (R57-F). Three sites are under continuous grass cover and the three under forest cover since reclamation. Three bulk soil samples were collected from each site from three landscape positions (upper; middle, and lower) for 0-15 and 15-30 cm depths. The samples were air dried and using wet sieving technique were fractionated into macro (> 2mm), meso (2-0.25 mm) and microaggregate (0.25-0.053 mm). These fractions were weighted separately and water stable aggregation (WSA) and geometric mean (GMD) and mean weight (MWD) diameters of aggregates were …
