Strongly bounded groups and infinite powers of finite groups
We define a group as strongly bounded if every isometric action on a metric
space has bounded orbits. This latter property is equivalent to the so-called
uncountable strong cofinality, recently introduced by G. Bergman.
Our main result is that G^I is strongly bounded when G is a finite, perfect
group and I is any set. This strengthens a result of Koppelberg and Tits. We
also prove that omega_1-existentially closed groups are strongly bounded.Comment: 10 pages, no figure. Versions 1-3 were entitled "Uncountable groups

Peran Komunikasi Penyuluhan dalam Penerapan Teknologi USAhatani di Kecamatan Langowan Barat
This study aims to determine the role of communication extension counselor and how far farmers can understand the purpose and purpose of counseling. This research was conducted by using primary data obtained from direct interview with Field Extension Officer and Farmer Group using the prepared kusioner. Secondary data obtained from BPS Manado City and BP3K Office. The result of the research shows that the communication done by PPL has used good communication technique so that the farmer group following the counseling can receive and understand the intent and purpose of the material which have been submitted by each PPL
Shape computations without compositions
Parametric CAD supports design explorations through generative methods which compose and transform geometric elements. This paper argues that elementary shape computations do not always correspond to valid compositional shape structures. In many design cases generative rules correspond to compositional structures, but for relatively simple shapes and rules it is not always possible to assign a corresponding compositional structure of parts which account for all operations of the computation. This problem is brought into strong relief when design processes generate multiple compositions according to purpose, such as product structure, assembly, manufacture, etc. Is it possible to specify shape computations which generate just these compositions of parts or are there additional emergent shapes and features? In parallel, combining two compositions would require the associated combined computations to yield a valid composition. Simple examples are presented which throw light on the issues in integrating different product descriptions (i.e. compositions) within parametric CAD
Bauran Pemasaran Buah Durian di Kawasan Boulevard Mall, Kota Manado
The purpose of this study was to identify elements in "Marketing Mix 4P" which applies to the marketing of durian at Boulevard Mall, Manado. This research was carried out for 2 months from April to May 2016. Data was retrieved through a survey consisting of primary and secondary data. Data was collected using a "purposive sampling" method, intentionally interviewing six respondents from fifteen respondents in the area of Boulevard Mall, Manado. There are four types of durians sold in Boulevard Mall: durian gajah, durian susu, durian mentega, and durian madu. Prices are relatively affordable and vary based on the type, with the highest price being durian gajah. The sale location in Boulevard Mall was selected by the sellers because it is within easy reach of the southern part of Manado and has a lively atmosphere. It is close to the beach, which is an ideal setting for relaxing while enjoying durian. Sellers promote their goods to consumers by offering an opportunity to bid prices, giving bonuses when consumers buy a certain amount, offering delivery services, and giving consumers the opportunity to taste test it for free
Free subgroups of one-relator relative presentations
Suppose that G is a nontrivial torsion-free group and w is a word over the
alphabet G\cup\{x_1^{\pm1},...,x_n^{\pm1}\}. It is proved that for n\ge2 the
group \~G= always contains a nonabelian free subgroup.
For n=1 the question about the existence of nonabelian free subgroups in \~G is
answered completely in the unimodular case (i.e., when the exponent sum of x_1
in w is one). Some generalisations of these results are discussed.Comment: V3: A small correction in the last phrase of the proof of Theorem 1.

The Kervaire-Laudenbach conjecture and presentations of simple groups
The statement ``no nonabelian simple group can be obtained from a nonsimple
group by adding one generator and one relator"
1) is equivalent to the Kervaire--Laudenbach conjecture;
2) becomes true under the additional assumption that the initial nonsimple
group is either finite or torsion-free.
Key words: Kervaire--Laudenbach conjecture, relative presentations, simple
groups, car motion, cocar comotion.

Probing small-x parton densities in proton- proton (-nucleus) collisions in the very forward direction
We present calculations of several pp scattering cross sections with
potential applications at the LHC. Significantly large rates for momentum
fraction, x, as low as 10^-7 are obtained, allowing for possible extraction of
quark and gluon densities in the proton and nuclei down to these small x values
provided a detector with good acceptance at maximal rapidities is used.Comment: 14 pages, LaTeX, 12 figures, uses revtex.st
