Business Incubators: Leveraging Skill Utilization through Social Capital
This study examines the role that social capital among tenant companies of a business incubator plays in the acquisition and utilization of business skills by those companies. Social capital is a resource derived from the structure and content of social relations among individuals or groups. Questionnaire data were gathered from 53 managers (primarily owners) of tenant companies in five incubators established by the State Privatization Office of the Turkish Republic. As hypothesized, relational social capital and cognitive social capital each had a significant unique and positive relationship with skill utilization. Contrary to a hypothesis, structural social capital did not have a significant unique relationship with skill utilization. These results indicate that incubator tenant companies' skill utilization is enhanced by social capital generated from the content of relations between the companies such as whether they trust and identify with each other and whether they share a common language and perspective
The Alia musica and the Carolingian Conception of Mode
The Alia musica is perhaps the most idiosyncratic of the early treatises on the ecclesiastical modes. It is a composite made up of at least three independent treatises and additional commentary, and the majority of the scholarly attention that it has thus far received has been devoted to questions of dating and authorship, as well as to the place of the Alia musica in the development of the octave species paradigm of modality. However, the majority of the treatise is dedicated to the explanation of a complex harmonic numerology that applies the fundamental relation 12:9:8:6 (which generate the intervals of an octave, a fifth, and a fourth) in a unique way to each of the eight ecclesiastical modes to define a set of intervals thought to be particularly characteristic of the chants in each mode.
This dissertation reviews the previous studies about the Alia musica, as well as the manuscript sources, examines the theoretical context within which the treatise was written, and analyzes the numerological system both from the evidence of the text of the Alia itself and from an analysis of the chants that the Alia cites as exemplifying the numerical relations proposed for each mode. The intervals represented by these numbers show only partial consistency and can generally be explained as being constructed from the simplest, or perhaps the most numerologically meaningful, multiples of the four base numbers from 12:9:8:6 that successfully filter out the intervals that are not considered to characterize a particular mode
Efektivitas Limbah Cengkih dalam Menekan Perkembangan In Vitro Sclerotium rolfsii, Jamur Penyebab Damping Off Kacang Tanah
Various problems have caused the decline in peanut production, among others the low resistance of peanut plants to various diseases. One of the obstacles in peanut production is the attack of plant diseases, such as the fungus Sclerotium rolfsii Sacc. The use of plant-based insecticides can be an alternative to disease control in peanuts. This study aimed to obtain the appropriate and effective dose of clove leaves and flower stalks in suppressing the in vitro growth of the fungus S. rolfsii Sacc causing damping off in peanuts, and to test the effectiveness of clove leaves and flower stalks on the formation of sklerotia of the fungus. This study used ‘tuni’ clove powder from Waai Village, Salahutu District. This experimental study employed a completely randomized design (CRD) with 8 treatments and 3 replications. The results showed that the growth of the fungus S. rolfsii Sacc. was inhibited by clove flower stalk powder at a dose of 1.5 g per100 mL of PDA, which was indicated by the number of sklerotia formed of 13.67% and propagule weight of 0.12 g, followed by a dose of clove leaf powder of 1.5 g per100 mL PDA, with amount of sklerotia formed of 27.33% and propagule weight of 0.17 g. These results were statistically shown on the parameters: colony diameter, Sklerotia formation time, number of Sklerotia, and weight of propagules.

ABSTRAK
Berbagai masalah telah menyebabkan turunnya produksi kacang tanah, diantaranya masih rendahnya ketahanan tanaman kacang tanah terhadap berbagai penyakit. Salah satu kendala dalam produksi kacang tanah adalah serangan penyakit tanaman, seperti jamur Sclerotium rolfsii Sacc. Penggunaan insektisida nabati dapat menjadi alternatif pengendalian penyakit pada kacang tanah. Penelitian ini bertujuan untuk memperoleh dosis daun dan tangkai bunga cengkih yang tepat dan efektif dalam menekan pertumbuhan jamur S. rolfsii Sacc penyebab damping off pada kacang tanah secara in vitro, serta menguji efektifitas daun dan tangkai bunga cengkih terhadap pembentukan sklerotia jamur. Penelitian ini menggunakan bubuk cengkih tuni, dari Desa Waai, Kecamatan Salahutu. Penelitian eksperimental ini menggunakan Rancangan Acak Lengkap (RAL) dengan 8 perlakuan dan 3 ulangan. Hasil penelitian menunjukkan bahwa pertumbuhan jamur S. rolfsii Sacc. terhambat oleh bubuk tangkai bunga cengkih pada dosis 1,5 g per 100 mL PDA yang ditunjukan oleh jumlah sklerotia terbentuk 13,67% dan berat propagul 0,12 g dan diikuti oleh dosis bubuk daun cengkih 1,5 g per 100 mL PDA, dengan jumlah sklerotia 27,33% dan berat propagul 0,17 g. Hasil ini secara statistik ditunjukkan pada parameter: diameter koloni, waktu terbentuk sklerotia, jumlah sklerotia, dan berat propagul.

HSV-NIS, an oncolytic herpes simplex virus type 1 encoding human sodium iodide symporter for preclinical prostate cancer radiovirotherapy
Several clinical trials have shown that oncolytic herpes simplex virus type 1 (oHSV-1) can be safely administered to patients. However, virus replication in tumor tissue has generally not been monitored in these oHSV clinical trials, and the data suggest that its oncolytic potency needs to be improved. To facilitate noninvasive monitoring of the in vivo spread of an oHSV and to increase its antitumor efficacy, the gene coding for human sodium iodide symporter (NIS) was incorporated into a recombinant oHSV genome and the corresponding virus (oHSV-NIS) rescued in our laboratory. Our data demonstrate that a human prostate cancer cell line, LNCap, efficiently concentrates radioactive iodine after the cells have been infected in vitro or in vivo. In vivo replication of oHSV-NIS in tumors was noninvasively monitored by computed tomography/single-photon emission computed tomography imaging of the biodistribution of pertechnetate and was confirmed. LNCap xenografts in nude mice were eradicated by intratumoral administration of oHSV-NIS. Systemic administration of oHSV-NIS prolonged the survival of tumor-bearing mice, and the therapeutic effect was further enhanced by administration of 131I after the intratumoral spread of the virus had peaked. oHSV-NIS has the potential to substantially enhance the outcomes of standard therapy for patients with prostate cancer

Implementation of drift velocities and currents in SOLEDGE2D-EIRENE
International audienceIn order to improve cross-field transport description, drifts and currents have been implemented in SOLEDGE2D-EIRENE. The derivation of an equation for the electric potential is recalled. The resolution of current equation is tested in a simple slab case. WEST divertor simulations in forward-B and reverse-B fields are also discussed. A significant increase of ExB shear is observed in the forward-B configuration that could explain a favorable L-H transition in this case
Human Challenge Pilot Study with Cyclospora cayetanensis
We describe a pilot study that attempted to infect human volunteers with Cyclospora cayetanensis. Seven healthy volunteers ingested an inoculum of Cyclospora oocysts (approximately 200–49,000 oocysts). The volunteers did not experience symptoms of gastroenteritis, and no oocysts were detected in any stool samples during the 16 weeks volunteers were monitored

Acute tubulo-interstitial nephritis leading to acute renal failure following multiple hornet stings
BACKGROUND: Hornet stings are generally associated with local and occasionally anaphylactic reactions. Rarely systemic complications like acute renal failure can occur following multiple stings. Renal failure is usually due to development of acute tubular necrosis as a result of intravascular haemolysis, rhabdomyolysis or shock. Rarely it can be following development of acute tubulo-interstitial nephritis. CASE PRESENTATION: We describe a young male, who was stung on face, head, shoulders and upper limbs by multiple hornets (Vespa orientalis). He developed acute renal failure as a result of acute tubulo-interstitial nephritis and responded to steroids. CONCLUSION: Rare causes of acute renal failure like tubulo-interstitial nephritis should be considered in a patient with persistent oliguria and azotemia following multiple hornet stings. Renal biopsy should be undertaken early, as institution of steroid therapy may help in recovery of renal functio
