The Common Kitchen : a culinary incubator

The Common Kitchen opened in August 2006 as Southern New Hampshire University's first culinary incubator. The mission of The Common Kitchen was to help early stage entrepreneurs get started in the retail food business by providing support systems, resources, and facilities at little or no cost. The Common Kitchen targeted two groups of people: (1) entrepreneurs of southern New Hampshire looking to grow their food-based business beyond the walls of their home and (2) low-income and ethnic minority residents of Manchester interested in developing their own micro business. The Common Kitchen was located in a dormant kitchen lab at SNHU's School of Hospitality, Tourism and Culinary Management. Tenants could rent the commercially licensed space for an hourly fee, rent storage space for a monthly fee and order raw ingredients from the school's purchasing department. Under the direction of the assistant dean of the School of Hospitality, Tourism and Culinary Management two Community Economic Development masters students developed a system of operations for the kitchen and identified and enrolled kitchen tenants. Seven months after opening, a total of three tenants rented space from and produced food in The Common Kitchen. All of the tenants were Caucasian, with high levels of education from Master's Degrees to a PhD. The demographics of The Common Kitchen's final tenants highlighted the need for greater outreach to the low-income and ethnic minority community, as well as a deeper support system for individuals with little to no funding or entrepreneurial experience.

Numerical study of natural oscillations of supported drops with free and pinned contact lines

In the present study, the axisymmetric natural oscillations of a liquid drop supported by a flat surface is investigated by direct numerical simulation. The liquid-gas interface is captured using a geometric volume-of-fluid (VOF) method. A parametric study is carried out by varying the equilibrium contact angle and the gravitational Bond number (Bo). Both positive and negative gravities are considered, and thus the results cover both pendant and sessile drops. To incorporate the effect of contact line mobility, the two asymptotic limits, namely the pinned contact line (PCL) and free contact line (FCL) conditions, are considered and their effects on the drop oscillation features are characterized. The predicted oscillation frequencies for PCL and FCL serve as the upper and lower bounds for general situations. The drop oscillation is initiated by increasing the gravity magnitude for a short time. The first mode due to the drop centroid translation dominates the excited oscillation. The oscillation frequency scales with the capillary frequency, and the normalized frequency monotonically decreases with the equilibrium contact angle. For zero gravity, the computed frequencies for all contact angles agree remarkably well with the inviscid theory for both the PCL and FCL conditions. The kinetic energy correction factor is introduced to account for the additional contribution of the oscillation-induced internal flow to the overall kinetic energy of the drop. Both the frequency and the kinetic energy correction factor increase with Bo, decrease with the contact angle, and increase when the contact line condition changed from FCL to PCL. The variation of oscillation frequency due to the change of Bo is particularly significant when the contact angle is large

Disciplinary Movements, the Civil Rights Movement, and Charles Keil's Urban Blues

Charles Keil was in his midtwenties when he published his first book, Urban Blues (1966a), based on his master's thesis in anthropology at the University of Chicago. In many ways, it was the summation of his experiences and encounters up to that point: a childhood in rural Connecticut where his grandfather raised pigs; a love of jazz that began with drum lessons from his uncle (an example of what colleague Steven Feld described as "white male bonding through black music" [Keil and Feld 1994:2]); undergraduate schooling at Yale that included travel to the West Indies and Nigeria; 1960s countercultural activism intensified by a relationship with Malcolm X; a tumultuous graduate school experience under the tutelage of Clifford Geertz, David Schneider, and Marshall Sahlins in anthropology, Leonard Meyer in musicology, and Alan Merriam in ethnomusicology; and finally fieldwork in the theaters, nightclubs, radio stations, recording studios, and tour buses connected to the bustling blues scene in Chicago. The appearance of Urban Blues was not revolutionary because it came from the hand of a humanist prodigy, but because Keil approached a modern, urban African American musical style with such rigor. In the current disciplinary climate of critical musicology, ethnomusicology, anthropology, and Black Studies, it is difficult to grasp that Urban Blues was not only one of the first scholarly texts based on fieldwork in urban Afro-America, but was also one of the first ethnographic monographs dedicated to an American popular music form, and was the first to eschew transcription and detailed musical-structural analysis in favor of a sociocultural approach

A model to predict the oscillation frequency for drops pinned on a vertical planar surface

Accurate prediction of the natural frequency for the lateral oscillation of a liquid drop pinned on a vertical planar surface is important to many drop applications. The natural oscillation frequency, normalized by the capillary frequency, is {mainly} a function of the equilibrium contact angle and the Bond number (Bo), when the contact lines remain pinned. Parametric numerical and experimental studies have been performed to establish a comprehensive understanding of oscillation dynamics. {An} inviscid model has been developed to predict the oscillation frequency for wide ranges of Bo and contact angles. The model reveals the scaling relation between the normalized frequency and Bo, which is validated by the numerical simulation results. For a given equilibrium contact angle, the lateral oscillation frequency decreases with Bo, implying that resonance frequencies will be magnified if the drop oscillations occur in a reduced gravity environment

Interaction Between X-Irradiated Plateau-Phase Bone Marrow Stromal Cell Lines and Co-Cultivated Factor-Dependent Cell Lines Leading to Leukemogenesis in Vitro

Plateau-phase mouse clonal bone marrow stromal cell lines D2XRII and C3H c1 II produce decreasing levels of M-CSF (CSF-I), a specific macrophage progenitor cell humoral regulator, following x-irradiation in vitro. The decrease did not go below 40% of control levels, even after irradiation doses of 50,000 rad (500 Gy). In contrast, a distinct humoral regulator stimulating growth of GM-CSF/IL-3 factor-dependent (FD) hematopoietic progenitor cell lines was detected following radiation to doses above 2,000 rad. This humoral factor was not detectable in conditioned medium from irradiated cells, weakly detected using factor-dependent target cell populations in agar overlay, and was prominently detected by liquid co-cultivation of factor-dependent cells with irradiated stromal cell cultures. Subclonal lines of FD cells, derived after co-cultivation revealed karyotypic abnormalities and induced myeloblastic tumors in syngeneic mice. Five - eight weeks co-cultivation was required for induction of factor independence and malignancy and was associated with dense cell to cell contact between FD cells and stromal cells demonstrated by light and electron microscopy. Increases in hematopoietic to stromal cell surface area, total number of adherent cells per flask, total non-adherent cell colonies per flask, and cumulative non-adherent cell production were observed after irradiation. The present data may prove very relevant to an understanding of the cell to cell interactions during x-irradiation-induced leukemia

Linear stability analysis of Mach 10 nitrogen flow over 7-deg half-angle cones.

Linear stability theory (LST) analysis was performed on Mach 10 7-degree half-angle straight cones in nitrogen for comparison with experimental results obtained in the Arnold Engineering Development Complex (AEDC) Hypervelocity Wind Tunnel 9. The basic states considered were either generated by STABL at Sandia National Laboratories or with US3D at Baylor University. The LST analysis reproduced the trends of laminar-turbulent transition front moving forward with increasing unit Reynolds number for a sharp nose cone as well as the trend in transition front moving aft as nose bluntness is increased at a constant unit Reynolds number. The strengths of the instabilities were found to be consistent with those measured experimentally. It is hypothesized that the nose bluntness transition trends can be understood by analyzing the thermoacoustic impedance layer

Numerical and theoretical study of natural oscillations of supported drops with free and pinned contact lines.

The oscillation of drops supported by solid surfaces is important to a wide variety of applications, such as dropwise condensation. Identification of the natural frequencies of supported drops of different sizes and liquids on different material surfaces is essential to developing techniques to enhance drop shedding using acoustics or surface vibration. This dissertation presents a systematic investigation of the effect the contact angle, the gravitational Bond number, the contact line mobility, and the perturbation force angle on the natural frequencies of the drop through parametric direct numerical simulation. The open-source multiphase flow solver, Basilisk, has been used for both 2D-axisymmetric and full 3D simulation. The geometric volume-of-fluid method has been used to capture the drop surface. Two asymptotic limits of contact line mobility, the free and pinned contact lines are considered. The results show that the for all the oscillation modes, the frequency scales with the capillary frequency. For the axisymmetric longitudinal modes, normalized frequency decreases with the contact angle, increases with the gravitational Bond number, and increases when the contact line changes from the free to pinned conditions. For the lateral oscillation mode, the variation trends of the oscillation frequency with the contact angle and contact line mobility remain the same, but the frequency slightly decreases with the Bond number. The simulation results match with inviscid theory remarkably well and also agree well with the experimental data on different material surfaces. An inviscid theoretical model is also established. The model yields expressions for the frequency as a function of the contact angle and the Bond number, with all parameters involved fully determined by the equilibrium drop theory and the simulation. The model predictions are compared with the simulation results and excellent agreement is achieved
