Abstract Biopolymers, like chromatin, are often confined in small volumes. Confinement has a great effect on polymer conformations, including polymer entanglement. Polymer chains and other filamentous structures can be represented by polygonal curves in 3-space. In this manuscript, we examine the topological complexity of polygonal chains in 3-space and in confinement as a function of their length. We model polygonal chains by equilateral random walks in 3-space and by uniform random walks in confinement. For the topological characterization, we use the second Vassiliev measure. This is an integer topological invariant for polygons and a continuous functions over the real numbers, as a function of the chain coordinates for open polygonal chains. For uniform random walks in confined space, we prove that the average value of the Vassiliev measure in the space of configurations increases as $O(n^2)$ with the length of the walks or polygons. We verify this result numerically and our numerical results also show that the mean value of the second Vassiliev measure of equilateral random walks in 3-space increases as $O(n)$. These results reveal the rate at which knotting of open curves and not simply entanglement are affected by confinement.

In the game of futsal, work of postural muscle balance needed to maintain the stability of the body for receiving the pass and put the ball into the other team's goal at the time of attack, changing the direction of movement quickly when returning to their respective positions and avoid of back disorder. This research is a form of experimental research that will test the effectiveness of the provision of trunk balance exercise is better than the strengthening of back exercises to improve muscle work balance of erector spine on futsal beginner players, in this study sample will be divided into two groups, the first group will be given trunk balance exercise to improve balance of erectorspine muscles work in futsal begginer players, the second group will be given back strengthening exercise to improve balance of erectorspine muscles work in futsal begginer players.This study was conducted for 6 weeks and the intervention performed 18 times during the study period. Samples measured by surface electromyography to measure work of right and left erector muscle by calculating the proportion of the work on the muscle, the measurement is performed at before the intervention and then intervention in accordance with the grouping which has been divided and then after completion of the intervention, the samples will be re-measured to obtain the value of the intervention.The results of the first group who has been given of trunk balance exercise shows the average value of the before treatment (83.82 ± 2.94) % and the mean value of the after treatment (96.74 ± 2.39) %, and in the second group who has been given strengthening back exercise shows the mean value of the before treatment (88.29 ± 1.89) % and the mean value after treatment (95.91 ± 1.75) %, with the probability value of both groups is 0.000 (p <0.05), and can be expressed there is a significant difference between both groups. In the fourth hypothesis test conducted comparative results of both groups, using independent samples t-test using mean value of the first and second groups, in the first group (12.92 ± 2.94) %, and the second group (7.61 ± 2.12) %, with a probability value 0.000 (p<0.05) and can be expressed in statistical analysis is no significant difference between both treatments were carried out and that means, giving trunk balance exercise is better than back strengthening exercise to improve balance of erector spine muscles work on futsal beginner players.

To determine experimentally the mean value of a randomly fluctuating quantity, it may be necessary to measure the average value over a considerable interval of time. This problem arose in a recent study of the temperature fluctuations over a heated horizontal plate, and a system was used that depended on the counting of electrical pulses generated at a rate proportional to the quantity being measured. The advantage of this technique is that mean values may be measured over time intervals of almost unlimited length with little added difficulty for the experimenter. Circuits are described which measure: (a) the mean square of a fluctuating quantity and of its time-derivative, (b) the statistical distribution of the fluctuations, (c) the mean frequency of the fluctuation assuming a particular value, and (d) the mean product of two fluctuating quantities. Over the range of use, the stability and linearity of the calibrations is better than 1%, more than sufficient for work on natural convection. In its present form, the equipment responds uniformly to all frequencies below 100 c/s, but it would not be difficult to extend this range of response to higher frequencies.

An injection system is a process of burning fuel on an internal combustion engine by using an electronic system to inject fuel with air into the combustion chamber. The carburetor system uses a nozzle to blur the fuel mixture with the combustor air. The purpose of this study was to determine differences in the value of fuel consumption from the injection system with the carburetor system. This research was conducted by the experimental method. The results of the analysis showed that the average value of fuel consumption even with the injection system was 51.53ml, while the mean value of the carburetor system was 90.40 ml, this meant that the injection system was more efficient compared to the carburetor system of 44.89 ml or 47%. Conclusion injection system at any rotation is more economical than the carburetor system. It is recommended to conduct further research by taking real data that is distance and travel time.

Abstract: Changes to respiratory function due to regular aerobic exercise will affect the value of pulmonary function, especially in Forced Vital Capacity (FVC). This research aimed to determine the effect of aerobic exercise on FVC overweight male students of Unsrat Medical Faculty. This research is analytic with design experimental, one group pre and post test design. The sampling technique used is non-purposive sampling technique. The research sample was taken from the students of the Faculty of Medicine 2009, Univercity of Sam Ratulangi who fulfill the inclusion criteria. Some 32 students were selected as research subjects. After giving informed consent, FVC measurement was done with the spirometer. After it was measured, they were given treatmen in the form aerobic exercise using a stationary bike for three weeks with frequency of exercise three times a week and exercise intensity for 30 minutes. We measured again FVC values after the exercise three times program. Normality test data showed significance for FVC value before treatment by 0.752, and after treatment by 0.912. Comparison of the average value before and after exercise were tested by using a paired test. Significant value for FVC is P = 0.084, means there is no significant difference between FVC values before and after exercise (P> 0.05). The mean FVC was 3.88 before treatment and after treatment the mean value was 4.00, an increase in the average value of 0.11. Conclusion:Aerobic Exercise on a regular basis using a stationary bike on the overweight male student can improve lung function in particular the mean FVC but there was no significant difference from the mean value.
