where i, j, and t are firm-, industry-, and time-specific subscripts. Yit is the output of firm i in year t in the form of total sales, and Y j is the corresponding geometric mean in industry j. xit denotes the use of factor z. We consider three factors of production, labor, capital, and material input costs. Labor input is measured by the total wage bill, capital by gross fixed assets, and mat...

Community-based growth promotion (CBGP) delivered by community volunteers aims at enhancing the traditional growth monitoring and promotion (GMP) program delivered by community health nurses through the promotion of optimum infant and young child feeding (IYCF) leading to improved child growth. This study compared IYCF knowledge and practices among caregiver-child pairs (0-24 months) receiving ...

abstract the saturated hydraulic conductivity (ks) is an important physical property of soil. the direct measurement of this property in soils is a difficult and time consuming process. pedotransfer functions (ptfs) provide an alternative by estimating soil parameters from more readily available soil data. the objective of this study is to determine effective factors on soil hydraulic conductiv...

Drought hasunfavorable impacts on the success of agriculture in many parts world.Providing future populations with enough food would obviously require evaluation crop yield, higher potentials, and provision yield stability drought-affected regions. In this research, drought-tolerance wheat genotypes was studied a randomized complete block design three-replication experiment under normal drought...

For a,b > 0 with a = b , let P = (a− b)/(4arctana/b−π) , A = (a+ b)/2 , G = √ ab denote the Seiffert mean, arithmetic mean, geometric mean of a and b , respectively. In this paper, we present new sharp bounds for Seiffert P in terms of weighted power means of arithmetic mean A and geometric mean G : ( 2 3 A p1 + 3 G p1 )1/p1 < P < ( 2 3 A p2 + 3 G p2 )1/p2 , where p1 = 4/5 and p2 = logπ/2 (3/2)...

In this short note, we present a refinement of the logarithmic-geometric mean inequality. As an application of our result, we obtain an operator inequality associated with geometric and logarithmic means.

Epidemiological studies have reported process-specific elevated prevalence of beryllium sensitization (BeS) and chronic beryllium disease (CBD) among workers. However, exposure-response relationships have been inconsistent, possibly due to incomplete characterization of many biologically relevant aspects of exposure, including particle size. In 1999, two surveys were conducted 3-5 months apart ...

It is well-known that for Hilbert space linear operators 0 ≤ A and 0 ≤ C, inequality C ≤ A does not imply C ≤ A. We introduce a strong order relation 0 ≤ B≪ A, which guarantees that C ≤ BAB for all 0 ≤ C ≤ B, and that C ≤ A when B commutes with A. Connections of this approach with the arithmetic-geometric mean inequality of Bhatia–Kittaneh as well as the Kantorovich constant of A are mentioned.

T his article describes an important improvement in the calculation of the Consumer Price Index (CPI). The Bureau of Labor Statistics plans to use a new geometric mean formula for calculating most of the basic components of the Consumer Price Index for all Urban Consumers (CPI-U) and the Consumer Price Index for Urban Wage Earners and Clerical Workers (CPI-W). This change will become effective ...
