Precision Feeding in Dairy Ration Cost Minimization Under Producer's Risk Management

The biophysical simulation data from Cornell Net Carbohydrate and Protein System were used in non-linear programming model for least cost ration incorporating ingredient nutrient and price variations. Precision feeding practice indicated to have lower mean cost ration than whole herd feeding in terms of ration cost.Non-linear programming, nutrient variation, price variation, precision feeding, environmental pollution, phosphorus, nitrogen, mean cost ration, whole herd feeding, Livestock Production/Industries, Risk and Uncertainty,

Risk management on application of minimum-cost feed ration for nitrogen and phosphorus reduction on dairy farm

The traditional mathematical programming model with the objective function of feed ration cost minimization is used to accommodate risk management responses to price variability associated with feeding a particular feed ration over time. The model incorporated biophysical simulation data using Cornell Net Carbohydrate and Protein System (CNCPS) software in addressing nutrient requirements and excretions. In addition, it used historic feedstuff prices in a mean-variance (E-V) framework analysis. The optimized seasonal feeding indicated to have a lower mean ration cost and lowest nutrient loading followed by optimized uniform feeding program. The feed cost optimization proved to be a better strategy in minimizing ration cost and reducing excretions both manure and nutrients. The results in this study can be used as guidelines for making nutrient. The information in this study can be used by a producer facing feed price risk to select optimal ration while reducing environmental pollution.Risk and Uncertainty,

Politik Identitas Di Maluku Utara

Identity politics became the main focus in the context of direct ELECTION, so that in practice involves the role of informal actors and the structure of the party and the bureaucracy. The political process gave birth to the spirit of ethnic identity growing stronger in Malaku Utara gubernatorial election of 2013. First, ethnic identity politics provide a large space will rise spirit of the actors to strengthen and raise the position of the elite and the local authorities in Maluku Utara. Secondly, the role of actor and structure is a challenge for political parties in aderah. Third, the politics of ethnic identity that developed in Maluku Utara, which is based on the true spirit of pragmatism mendorng ethnic ethnicity into a political force that is gentle to the birth of a harmonious political culture for the creation of a good climate of democracy in the province of Maluku Utara

An Integrated Precision Production and Environmental Management Analysis of a Kentucky Dairy Farm

This study compares and contrasts the profitability of different dairy management practices through precision livestock farming. Feed analysis and crop yields were simulated. The proposed alternative feeding program demonstrated less manure and nutrient excretions. When mathematical programming model was employed, uniform rate application manifested the highest selected economic values.Management practices, environmental, Environmental Economics and Policy,

Comparison of Decision Rules for Subsurface Drip Irrigation Practices Using a Nonlinear Mathematical Programming Model

A comparison of decision rules has been made for case studies of corn production using subsurface drip irrigation under three agricultural management practices (no irrigation, uniform irrigation, and variable rate irrigation). The uniform irrigation strategy appeared to perform the best than the other two management practices under different risk scenarios.corn production, mathematical programming, profitability, risk management, subsurface drip irrigation, variable rate irrigation, Farm Management,

Resyllabification of Loan Words in Kalenjin Phonology

The description of syllable structure in the individual languages is important in realizing syllabic markedness which motivates re-syllabification in the recipient language. The paper threrefore is an analysis of re-syllabification of Kipsigis and Tugen loan words borrowed from Kiswahili langauge.  The paper also gives an overview of the syllable structure in Kipsigis and Tugen as the recepient languages and Kiswahili as the source language. Data analysis was guided by consonant vowel (C.V) phonological framework. The study found out that resyllabification is a morphophonological process during word formation in any given language.

The Core Composition of a White Dwarf in a Close Double Degenerate System

We report the identification of the double degenerate system NLTT 16249 that comprises a normal, hydrogen-rich (DA) white dwarf and a peculiar, carbon-polluted white dwarf (DQ) showing photospheric traces of nitrogen. We disentangled the observed spectra and constrained the properties of both stellar components. In the evolutionary scenario commonly applied to the sequence of DQ white dwarfs, both carbon and nitrogen would be dredged up from the core. The C/N abundance ratio (~ 50) in the atmosphere of this unique DQ white dwarf suggests the presence of unprocessed material (14N) in the core or in the envelope. Helium burning in the DQ progenitor may have terminated early on the red-giant branch after a mass-ejection event leaving unprocessed material in the core although current mass estimates do not favor the presence of a low-mass helium core. Alternatively, some nitrogen in the envelope may have survived an abridged helium-core burning phase prior to climbing the asymptotic giant-branch. Based on available data, we estimate a relatively short orbital period (P <~ 13 hrs) and on-going spectroscopic observations will help determine precise orbital parameters.Comment: Accepted for publication in ApJ Letter

Work Life Balance-Art of Prioritizing

Balancing work and life is a comfortable state of equilibrium achieved between an employee's primary priorities of their employment position and their private lifestyle.Positive work-life balance is the product of greater flexibilityemployees want greater control of their work and their schedules.As with most things in life, moderation is the key. People who are constantly tied to their jobs deal with the symptoms of stress and burnout. Overworked employees are more likely to suffer health problems, more like to be absent and/or sick, less efficient, less sociable, and overall more difficult to work with. It is in the best interest of both the employee and employer to avoid these pitfalls through smart human resource management
