Development of Supply Chain Quality Management in Peruvian Blueberry Companies: A Case Study in Cañete, Peru

The keen research objective is to develop a quality system in the Supply Chain Management geared to the agribusiness sector. The Supply Chain Quality Management (SCQM) proposed for blueberry companies must improve their operational performance. This study includes micro and small agricultural enterprises located in the Caete region of Peru, where thanks to the interviews and questionnaires, it was possible to determine the critical practices, which will be applied in the agribusiness sector. An important point of this research is the literature review found to enrich the methodical procedures that are the most important practices of the innovative SCQM model. The research shows that the critical practices to develop the quality management in this sector are Customer Relationship Management, Supplier Relationship Management, Process Management and Human Resources Management. These correctly designed and implemented practices will lead to operational improvement and other qualitative advantages. This research turns out to be completely innovative because the use of the recently proposed technique of Quality Management into the Supply Chain combined with the best practices will be very useful knowledge to the agribusiness sector. The implementation and development of quality systems for the main practices of SCQM is a differentiating factor that is rare to find in similar research. On the other hand, the development of the Peruvian case study focused on the blueberry industry provides great practical value to supply chain operations management of quality. Finally, the knowledge embedded in SCQM applied to small blueberry companies in an emerging country can provideadded value to management to increase the competitiveness of the agribusiness sector

Modeling the Distribution of Organic Coffee Supply Chain from Junín Region, Peru

This research uses Supply Chain (SC) data gathered during the distribution and transportation activities of organic coffee. The purpose of this research is to analyze different ways in which crop-chain solutions are adopted in the region of Junn, Peru. The disintegration of the SC is revealed, as each cooperative member works uncoordinatedly on his own leading to different results standards with high costs and low returns. The study focused on different entities from farmers to the port of Callao of an organic coffee supply chain where disintegration is constant. The paper describes a misaligned supply chain including poorly collaboration. All problems found will be an opportunity to develop a distribution model in the organic coffee supply chain of Junn region

The thermodynamics of perchlorates. I. Heat capacity of ND4ClO4 from 7 to 345 K and the analysis of heat capacities and related data of NH4ClO4 and ND4ClO4

The heat capacity of the orthorhombic salt: deuterated ammonium perchlorate, ND4 ClO4 , was measured from 7 to 345 K using adiabatic calorimetry. The heat capacity against temperature curve is smooth, continuous and without anomaly. Values of the standard molar thermodynamic quantities are presented up to 340 K. The heat capacities of ND4 ClO4 and NH4 ClO4 have been analyzed. The contributions to the vibrational heat capacity from the external optical modes of NH+4 or ND+4, ClO−4 and libration from the external modes of ClO−4 along with those of vibration from the internal optical modes of NH+4 or ND+4 and ClO−4, and the acoustic lattice modes for these ions have been calculated. The difference between the experimental and calculated heat capacity, called the residual heat capacity, equals the contribution from ammonium ion rotation and the thermal expansion of the lattice. With recent thermal expansion data, the correction from constant stress to constant strain has been applied and the derived rotational heat capacities of the NH+4 and ND+4 are determined to be in qualitative agreement with those derived from various rotational models.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/70290/2/JCPSA6-91-1-399-1.pd

The thermodynamics of ammonium scheelites. III. An analysis of the heat capacity and related data of deuterated ammonium perrhenate ND4ReO4

An analysis of the heat capacity of deuterated and undeuterated NH4ReO4 has been carried out in which the effects of the anisotropy of the thermal expansion have been considered, an approach hitherto not used for ammonium compounds. In the ammonium scheelites, the axial thermal expansion coefficients are very large, but of opposite sign, and as a result the volume of the scheelite lattice is nearly independent of temperature. It is shown that the correction from constant stress to constant strain results in a major contribution to the heat capacity of this highly anisotropic lattice. The difference between the experimental and calculated values of heat capacity, referred to as ΔCp, is expressed as the sum of the contributions from the anisotropy and the rotational heat capacity. The results of the analysis show that the rotational contribution is much smaller then previously thought. However, the exact contribution of the anisotropy cannot be calculated at this time because the elastic constants are not known. In calculating the heat capacity, maximum use has been made of external optical mode frequencies derived from spectroscopic measurements.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/71156/2/JCPSA6-85-10-5963-1.pd

The heat capacity of the perovskite high‐TC superconductor YBa2Cu3O7−δ was measured from 5.3 to 350 K in an adiabatic calorimetric cryostat. A break in the heat‐capacity curve, associated with the critical temperature for superconductivity was observed between 90.09 and 92.59 K. The transition temperature was identified as 91.44 K, and ΔCp,m was calculated to be 0.559R at that temperature. The lattice heat capacity was evaluated by means of the recently developed Komada/Westrum phonon distribution model and the apparent characteristic temperature ΘKW was calculated to be 107.7 K. The excess electronic heat capacity for the superconducting phase was evaluated and the energy gap was identified as 234. R K. Excess contribution, resulting from magnetic impurities, was noted below 20 K. Thermodynamic properties at selected temperatures are presented.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/71226/2/JCPSA6-92-11-6794-1.pd

The thermodynamics of the divalent metal fluorides. II. Heat capacity of the fast ion conductor BaSnF 4 from 7 to 345 K

The heat capacity of the fast ion conductor BaSnF 4 was measured over the temperature range 7< T <345 K using adiabatic calorimetry. Our results show that a phase transition is not present. However, an anomalous rise in the molar heat capacity, C p,m , occurs in the region 210< T <310 K; the entropy change of this rise amounts to ΔS/R =0.112. This anomaly coincides with the temperature range where a break in the slope of the electrical conductivity has been observed, which results in a threefold decrease in the activation energy required in the temperature region above the break at 272 K. Standard molar thermodynamic functions are presented at selected temperatures from 5 to 345 K.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/44570/1/10765_2005_Article_BF01133276.pd
