PKM PENGEMBANGAN INOVASI PRODUK MAKANAN DAN MINUMAN YANG DIJUAL DI SEPUTARAN KAMPUS UNSRAT BAHU
Inovasi produk makanan dan minuman saat ini penting untuk dikembangkan karena industri makanan dan minuman merupakan industri yang besar di Indonesia yang menjadi salah produk andalan penyumbang PDB terbesar untuk industri non migas. Untuk itu perlu ada pengembangan inovasi produk makanan dan minuman yang dijual. Masalaha yang dihadapi oleh usaha makanan dan minuman di kantin dan UKM kampus adalah masih kurangnya inovasi karena kurangnya berpikir inovatif dari pelaku usaha yang menjual produk makanan dan minuman. Tujuan pengabdian ini adalah meningkatkan kemampuan inovasi dari usaha-usaha yang menjual makanan dan minuman di seputaran kampus khususnya di Kampus Unsrat Manado. Tahapan Kegiatan Yang Dilakukan Adalah peningkatan dan pelatihan ketrampilan serta pendampingan untuk peningkatan inovasi produk makanan dan minuman pada usaha makanan dan minuman di seputaran Kampus Unsrat Manado.______________________________________________________________________Kata Kunci : PKM, pengembangan inovasi, produk makanan dan minuman, KampusUnsrat, Bahu, Manad
Asymptotics of skew orthogonal polynomials
Exact integral expressions of the skew orthogonal polynomials involved in
Orthogonal (beta=1) and Symplectic (beta=4) random matrix ensembles are
obtained: the (even rank) skew orthogonal polynomials are average
characteristic polynomials of random matrices. From there, asymptotics of the
skew orthogonal polynomials are derived.Comment: 17 pages, Late
Lateral clearance between vehicles and bicycles on urban roads.
Paper presented at the 32nd Annual Southern African Transport Conference 8-11 July 2013 "Transport and Sustainable Infrastructure", CSIR International Convention Centre, Pretoria, South Africa.The clearance motorists allow when they overtake bicyclists is critical to the safety and level of service experienced by bicyclists in mixed traffic. Recent calls for mandatory minimum lateral clearances in South Africa indicate its importance to the bicycling and sustainable transport communities. This study reports on locally measured lateral clearances between bicycles and vehicles on urban roads in Tshwane. An ultrasonic device was used to measure passing clearances under varying traffic and roadway conditions, and the paper reports on the range and variability of the observed clearances.
A regression analysis was performed to identify the factors affecting lateral clearance, such as lane width, vehicular speed, and density. Guidance is offered around the combination of vehicle volume and lane width that can be expected to result in given levels of bicycle safety. This guidance might help practitioners to identify pro-actively roadways with high accident potential for cyclists, or to identify suitable roads for inclusion in an areawide safe bicycle network.This paper was transferred from the original CD ROM created for this conference.

Sturmian morphisms, the braid group B_4, Christoffel words and bases of F_2
We give a presentation by generators and relations of a certain monoid
generating a subgroup of index two in the group Aut(F_2) of automorphisms of
the rank two free group F_2 and show that it can be realized as a monoid in the
group B_4 of braids on four strings. In the second part we use Christoffel
words to construct an explicit basis of F_2 lifting any given basis of the free
abelian group Z^2. We further give an algorithm allowing to decide whether two
elements of F_2 form a basis or not. We also show that, under suitable
conditions, a basis has a unique conjugate consisting of two palindromes.Comment: 25 pages, 4 figure
High Pressure Thermoelasticity of Body-centered Cubic Tantalum
We have investigated the thermoelasticity of body-centered cubic (bcc)
tantalum from first principles by using the linearized augmented plane wave
(LAPW) and mixed--basis pseudopotential methods for pressures up to 400 GPa and
temperatures up to 10000 K. Electronic excitation contributions to the free
energy were included from the band structures, and phonon contributions were
included using the particle-in-a-cell (PIC) model. The computed elastic
constants agree well with available ultrasonic and diamond anvil cell data at
low pressures, and shock data at high pressures. The shear modulus and
the anisotropy change behavior with increasing pressure around 150 GPa because
of an electronic topological transition. We find that the main contribution of
temperature to the elastic constants is from the thermal expansivity. The PIC
model in conjunction with fast self-consistent techniques is shown to be a
tractable approach to studying thermoelasticity.Comment: To be appear in Physical Review
The impact of Stieltjes' work on continued fractions and orthogonal polynomials
Stieltjes' work on continued fractions and the orthogonal polynomials related
to continued fraction expansions is summarized and an attempt is made to
describe the influence of Stieltjes' ideas and work in research done after his
death, with an emphasis on the theory of orthogonal polynomials
Sex differences in nucleus accumbens transcriptome profiles associated with susceptibility versus resilience to subchronic variable stress
Depression and anxiety disorders are more prevalent in females, but the majority of research in animal models, the first step in finding new treatments, has focused predominantly on males. Here we report that exposure to subchronic variable stress (SCVS) induces depression-associated behaviors in female mice, whereas males are resilient as they do not develop these behavioral abnormalities. In concert with these different behavioral responses, transcriptional analysis of nucleus accumbens (NAc), a major brain reward region, by use of RNA sequencing (RNA-seq) revealed markedly different patterns of stress regulation of gene expression between the sexes. Among the genes displaying sex differences was DNA methyltransferase 3a (Dnmt3a), which shows a greater induction in females after SCVS. Interestingly, Dnmt3a expression levels were increased in the NAc of depressed humans, an effect seen in both males and females. Local overexpression of Dnmt3a in NAc rendered male mice more susceptible to SCVS, whereas Dnmt3a knock-out in this region rendered females more resilient, directly implicating this gene in stress responses. Associated with this enhanced resilience of female mice upon NAc knock-out of Dnmt3a was a partial shift of the NAc female transcriptome toward the male pattern after SCVS. These data indicate that males and females undergo different patterns of transcriptional regulation in response to stress and that a DNA methyltransferase in NAc contributes to sex differences in stress vulnerability
Piecewise Linear Models for the Quasiperiodic Transition to Chaos
We formulate and study analytically and computationally two families of
piecewise linear degree one circle maps. These families offer the rare
advantage of being non-trivial but essentially solvable models for the
phenomenon of mode-locking and the quasi-periodic transition to chaos. For
instance, for these families, we obtain complete solutions to several questions
still largely unanswered for families of smooth circle maps. Our main results
describe (1) the sets of maps in these families having some prescribed rotation
interval; (2) the boundaries between zero and positive topological entropy and
between zero length and non-zero length rotation interval; and (3) the
structure and bifurcations of the attractors in one of these families. We
discuss the interpretation of these maps as low-order spline approximations to
the classic ``sine-circle'' map and examine more generally the implications of
our results for the case of smooth circle maps. We also mention a possible
connection to recent experiments on models of a driven Josephson junction.Comment: 75 pages, plain TeX, 47 figures (available on request
The Infrared Continuum Spectrum of VY CMa
We combine spectra of VY CMa obtained with the short- and long-wavelength
spectrometers, SWS and LWS, on the Infrared Space Observatory to provide a
first detailed continuum spectrum of this highly luminous star. The
circumstellar dust cloud through which the star is observed is partially
self-absorbing, which makes for complex computational modeling. We review
previous work and comment on the range of uncertainties about the physical
traits and mineralogical composition of the modeled disk. We show that these
uncertainties significantly affect the modeling of the outflow and the
estimated mass loss. In particular, we demonstrate that a variety of quite
diverse models can produce good fits to the observed spectrum. If the outflow
is steady, and the radiative repulsion on the dust cloud dominates the star's
gravitational attraction, we show that the total dust mass-loss rate is yr, assuming that the star is at a distance of
1.5 kpc. Several indications, however, suggest that the outflow from the star
may be spasmodic. We discuss this and other problems facing the construction of
a physically coherent model of the dust cloud and a realistic mass-loss
analysis
