The Critical Exponent is Computable for Automatic Sequences
The critical exponent of an infinite word is defined to be the supremum of
the exponent of each of its factors. For k-automatic sequences, we show that
this critical exponent is always either a rational number or infinite, and its
value is computable. Our results also apply to variants of the critical
exponent, such as the initial critical exponent of Berthe, Holton, and Zamboni
and the Diophantine exponent of Adamczewski and Bugeaud. Our work generalizes
or recovers previous results of Krieger and others, and is applicable to other
situations; e.g., the computation of the optimal recurrence constant for a
linearly recurrent k-automatic sequence.Comment: In Proceedings WORDS 2011, arXiv:1108.341

Factors Related to Healing Process of Sectio Caesarea Surgical Wound
ABSTRACT
Sectio caesarea surgical wound is a disorder in the incontinence of cells due to surgery performed to remove the fetus and placenta by opening the abdominal wall for certain indications. The aim of the study was to analyze and make a modeling of the relationship of factors in healing the sectio caesarea surgical wounds. This research is an analytic observational study with cross-sectional design. The sample in this study were 42 mothers with post sectio caesarea surgery at Prof. DR. W.Z. Johannes Kupang Public Hospital. Sampling was performed by simple random sampling. Data analysis was carried out in a bivariate and multivariate analysis. The results of the bivariate analysis found that the variables that give risk to wound healing were age (p = 0.041; RP = 3.4), discharge planning (p = 0.004; RP = 4.75), personal hygiene (p = 0.003; RP = 0.18), nutritional status (p = 0.013; RP = 0.15). Multivariate analysis found three variables that consistently provide risks to wound healing, namely discharge planning (p = -2.078; RP = 829 95% CI), personal hygiene (p = -1.852; RP = 1.039 95% CI), nutritional status (p = -2,374; RP = 1,023 95% CI). Probability model for healing the surgical wound at Prof. Dr. W.Z. Johannes, namely personal hygiene, nutritional status, discharge planning are factors related to wound healing.

ABSTRAK
Luka operasi sectio caesarea adalah gangguan dalam inkontuinitas sel akibat dari pembedahan yang dilakukan untuk mengeluarkan janin dan placenta dengan membuka dinding perut atas indikasi tertentu. Tujuan penelitian untuk menganalisis dan membuat pemodelan hubungan faktor pada penyembuhan luka operasi sectio caesarea. Penelitian ini merupakan studi observasional analitik dengan desain cross sectional. Sampel pada penelitian ini sebanyak 42 ibu post operasi sectio caesarea di RSUD Prof. DR. W.Z. Johannes Kupang. Pengambilan sampel secara simple random sampling. Analisis data dilakukan secara bivariat dan multivariat. Hasil analisis bivariat menemukan variabel yang memberikan risiko terhadap penyembuhan luka adalah umur (p=0,041; RP=3,4), discharge planning (p=0,004; RP=4,75), personal hygiene (p=0,003; RP=0,18), status gizi (p=0,013; RP=0,15). Analisis multivariat menemukan tiga variabel yang konsisten memberikan risiko terhadap penyembuhan luka yaitu discharge planning (p= -2.078; RP=829 95% CI), personal hygiene (p= -1.852; RP= 1,039 95% CI), status gizi (p= -2.374; RP=1,023 95% CI). Model probabilitas penyembuhan luka operasi di RSUD Prof. Dr. W.Z. Johannes yaitu personal hygiene, status gizi, discharge planning merupakan faktor yang berhubungan dengan penyembuhan luka.

RESEARCHES ON AUTOMATION OF DOSING AND SACKING PROCESS OF FINISHED AGRICULTURAL PRODUCTS
Researches whose results are presented in this paper are on the topic of optimizing the dosing and sacking process in small and medium capacity productive units..The technological equipment for weighing and automated management EWAM, developed at INMA Bucharest performes simultaneously two operations: automated bag weighing of the programmed quantity of product and automated management of the quantities of sacked finished products on an indefinite period of time.In this paper there are presented the experimental researches for this equipment, working quality indices determined with highlighting the advantages of using this type of technical equipment in the flow of small and medium capacity milling units in villages
A SURVEY REGARDING THE NEWEST SEEDLINGS PLANTING TECHNOLOGIES THAT CAN BE USED IN AGROFORESTY, LANDSCAPE ECOLOGY AND FOREST REGENERATION FIELDS
Nowadays the seedlings planting technologies are design to raise mechanization performance on forestry and pomiculture works. Their impact is manly on soil remediation, lowering the surface and depth erosion degree, capitalization of rainwater, lowering the dust pollution and natural calamity risk and the rehabilitation of inland flora. In this paper will be presented some of the most performant planting technologies, which can be used in the environmental management process that assures high establishment rate. In some cases, the ecological benefits can occur after a shorter period of time reducing considerably the calamity risks, encouraged the inland flora, forest and degraded the site restauration, but also landscape ecology.Â
Impact of Visceral Leishmaniasis on Local Organ Metabolism in Hamsters.
Leishmania is an intracellular parasite with different species pathogenic to humans and causing the disease leishmaniasis. Leishmania donovani causes visceral leishmaniasis (VL) that manifests as hepatosplenomegaly, fever, pancytopenia and hypergammaglobulinemia. If left without treatment, VL can cause death, especially in immunocompromised people. Current treatments have often significant adverse effects, and resistance has been reported in some countries. Determining the metabolites perturbed during VL can lead us to find new treatments targeting disease pathogenesis. We therefore compared metabolic perturbation between L. donovani-infected and uninfected hamsters across organs (spleen, liver, and gut). Metabolites were extracted, analyzed by liquid chromatography-mass spectrometry, and processed with MZmine and molecular networking to annotate metabolites. We found few metabolites commonly impacted by infection across all three sites, including glycerophospholipids, ceramides, acylcarnitines, peptides, purines and amino acids. In accordance with VL symptoms and parasite tropism, we found a greater overlap of perturbed metabolites between spleen and liver compared to spleen and gut, or liver and gut. Targeting pathways related to these metabolite families would be the next focus that can lead us to find more effective treatments for VL
