The flux of noncommutative U(1) instanton through the fuzzy spheres
From the ADHM construction on noncommutative we investigate
different U(1) instanton solutions tied by isometry trasformations. These
solutions present a form of vector fields in noncommutative
vector space which makes possible the calculus of their fluxes through fuzzy
spheres. We establish the noncommutative analog of Gauss theorem from which we
show that the flux of the U(1) instantons through fuzzy spheres does not depend
on the radius of these spheres and it is invariant under isometry
transformations.Comment: 18 pages, new version to appear in Int. Jour. of Mod. Phys.

Identification of Pathogenic Bacteria of Selais (Ompok Hypopthalmus) Are Caught in the Kampar River Teratak Buluh Village in Riau Province
This research had been conducted in April up to June 2014 in LaboratoryofParasite andFish Diseases,Faculty of Fisheriesand Marine Sciencesof RiauUniversity. This research aims to find out the type of bacteria pathogenicpotentially infect slice of fish in the Kampar River, Teratak Buluh Village in RiauProvince. The adventages of this research is to provide the types of bacterialpathogens that potentially attack the slice of fish in the public water of Riau. Themethod applied in this research is survey methode by taking some samples in thefield ( in Kampar River ) and then analyzed in the laboratory. And the result isthere are five species of bacteria found namely Aeromonas sp, Basillus sp,Pseudomonas sp, Stapyhilococcus sp, and Edwardsiella sp
Analisis Lingkungan Kerja dan Beban Kerja terhadap Kinerja Perawat RSUD Petala Bumi Pekanbaru
This study aims to analyze the influence of environmental variables and workload on the performance of hospital nurses Petala Earth Pekanbaru. This study was conducted from December 2013 to January 2014.In this study consisted of three variables: the dependent variable and two independent variables. These variables are performance (Y), of environmental work (X1) and workload (X2). The study was conducted using a sample of 56 people. Research using census sampling technique by giving questionnaires to the respondents. In terms of data analysis, descriptive study using qualitative methods to explain the results of the study. Known to the state of Earth\u27s Hospital Petala very necessary to have an increased viability of hospitals Petala Earth for environmental issues. More conducive and good, then the nurse will feel comfortable in the work. Further to the workload in hospitals Petala Earth itself for the nurses felt not too big, but it is necessary to continually evaluate in order to implement an appropriate system for the nurses in that workload is not too heavy and can make the job go well and maksimam especially in caring for the patient. For most affect the performance of the nurses were working environment compared to the workload of nurses hospital Pekanbaru Petala Earth, for the work environment is a major concern for improving the performance of the nurses.
Pemberian Probiotik Bacillus SP Berasal Dari Udang Galah (Macrobranchium Rosenbergii De Man) Dan Udang Windu (Penaeus Monodon) Terhadap Status Kesehatan Ikan Nila(oreochormis Niloticus)
This research was conducted on October 2015 - June 2016, at the Laboratory of Microbiology and the Laboratory of Parasites and Fish Diseases, Faculty of Fisheries and Marine Sciences, University of Riau. The purpose of this study is to comprehend the probiotic Bacillus sp. from the digestive tract of the giant prawns (Macrobranchium rosenbergii DE MAN) and the black tiger shrimp (Panaeus monodon) for the health status of tilapia (Oreochormis niloticus). This study uses a Completely Randomized Design (CRD), which consists of three treatments and each of them uses three replications for the probiotic Bacillus sp. treatment of the digestive tract either from the giant prawns or the tiger shrimp. The Bacillus sp. treatment from the giant prawns are P1G (UG4 isolates), P2G isolates combined (UG1, UG2, UG3, UG4, and UG5) and as a control (P0).While the tiger shrimp are using P1W (UWH9 isolates), P2W isolates that combined (UWH1, UWH2, UWH8, UWH9 and UWH 10) and as a control (P0). Probiotics from each treatment were put into the medium water about 3 mL / container with a density of 104 CFU/ml. The results showed that the P1W treatment is the best treatment after infected by Streptococcus iniae for the health statusof tilapia, it is showed by the number of Erythrocytes 246.67x104 sel / mm, Haemoglobin level of 6633 g/dl, Hematocrytes 30.33%, and total Leukocytes 79,33x103 sel/mm3. Given by probiotics of Bacillus sp that originatit from the digestive tract of giant prawns and tiger shrimp through the water were able to maintain the health of tilapia (Oreochormis niloticus)
Sensitivitas Ekstrak Daun Xylocarpus SP. terhadap Bakteri Pseudomonas SP.
This research was conducted from November 2016 until April 2017 in the Parasites and Fish Disease Laboratory, Faculty of Fisheries and Marine, University of Riau and Integrated Chemical Laboratory, Faculty of Mathematics and Natural Science of Health Muhammadiyah University of Riau. The aims of this research was to determine the sensitivity of Xylocarpus sp. leaf extract on Pseudomonas sp., the range of Minimum Inhibitory Concentration (MIC) of Xylocarpus sp. leaf extract can inhibit the growth of Pseudomonas sp. and know the toxicity of Xylocarpus sp. leaf extract against African catfish, the LC50 test conducted by immersion for 24 hours. This research used an experimental method. The treatment that being used were giving Xylocarpus sp. leaf extract at a concentration of D1 (100%), D2 (90%), D3 (80%), D4 (70%), D5 (60%), D6 (50%), D7 (40%), D8 (30%), D9 (20%), D10 (10%) and Kp : control (cloramphenicol). The results showed showed that Xylocarpus sp. leaf extract can inhibit the growth of Pseudomonas sp. at a concentration of 10% with an average of 8,12 mm zone of inhibition. MIC test showed a concentration of 8,5% average number of colonies of bacteria as much as 248,67 × 108CFU/mL can inhibit the growth of Pseudomonas sp. LC50 Xylocarpus sp. leaf extract against African catfish by immersion for 24 hours in the concentration 8,6% (860 ppm)
Penggunaan Bahan Penyimpan Airdan Volume Pemberian Air Terhadap Pertumbuhan Bibit Kelapa Sawit (Elaeis Guineensisjacq.)di Main Nursery
This study aims to determine the effect of the storage material and the volume of irrigation water on the growth of oil palm seedlings in the Main Nursery and have been implemented in the Technical Implementation Unit of the Faculty of Agriculture, University of Riau from June to October 2014. The study used completely randomized design (CRD) with two factorial factors and three replications. The first factor is the use of water-storage material (A), which consists of 4 levels: A0: Without the use of water-retaining material A1: Hydrogel 25 g / 10 kg soil, A2: Cocopeat 500 g / 10 kg soil, A3: Trunk bananas 50 g / 10 kg of the ground and the second factor is the volume of irrigation (V), which consists of three levels, namely: V1: 1 liter / day / bib it V2: 1.5 liters / day / seed V3: 2 liters / day / seed. The results showed the use of water storage material and the volume of water giving no real effect on seedling height increase, in the number of leaves, wrap accretion hump, dry weight of seed and seedling quality indices but significant effect on the ratio of the root crown. Hydrogel combination of 25 g / 10 kg soil and water provision volume 1 liters / day / seed tends to further increase in the number of leaves, wrap accretion hump seed, seedling dry weight, and seed quality index, while the combination of cocopeat 500 g / 10 kg soil and volume the provision of water 2 liters / day / seed tends to further increase the high accretion canopy ratios of seed and seedling roots. The growth of oil palm seedlings tend to be better with the use of water storage hydrogel material and cocopeat. The growth of oil palm seedlings tend to be better than the entire treatment volume of water provision
