Abstract: Chlorine is a green halogen-shaped halogen gas at normal temperature and serves as bleach, stain remover and disinfectant. Chlorine is now widely used for bleaching rice so that less quality rice looks like quality rice. Chlorine is very toxic and causes mucous membrane irritation, highly reactive and very powerful oxidizer. The purpose of this research was to determine the difference of chlorine level in chlorinated rice washed once, twice and 3 times. The sample in this study amounted to 11 samples calculated by replication formula. Each sample was treated 3 times, ie 1 washed once, 2 washed twice and washed 3 times. The samples then examined by iodometric titration method. Based on the results of the study using ANOVA test, 11 samples obtained the average value of chlorine after washed once amount of 0.0176%, after washed twice amount of 0.0111%, and after washed 3 times amount of 0.0052% with the value significance p = 0.03 (p <0.05) at 95% confidence level which means there was a significant difference between chlorine levels in chlorinated rice washed once, twice and 3 times.Abstrak: Klorin merupakan unsur halogen berbentuk gas berwarna kuning kehijauan pada suhu normal danberfungsi sebagai pemutih, penghilang noda maupun desinfektan. Klorin sekarang banyak digunakan untuk bahan pemutih beras agar beras yang kurang berkualitas tampak seperti beras berkualitas. Klorin sangat toksik dan menyebabkan iritasi membran mukosa, sangat reaktif dan merupakan oksidator yang sangat kuat. Tujuan dari penelitian ini ialah untuk mengetahui perbedaan kadar klorin pada beras berklorin yang dicuci sebanyak 1 kali, 2 kali dan 3 kali. Sampel dalam penelitian ini berjumlah 11 sampel yang dihitung dengan rumus replikasi. Setiap sampel diberi perlakuan sebanyak 3 kali, yaitu 1 kali pencucian, 2 kali pencucian dan 3 kali pencucian. Sampel penelitian kemudian diperiksa dengan metode titrasi iodometri. Berdasarkan hasil penelitian menggunakan uji Anova secara komputerisasi terhadap 11 sampel diperoleh nilai rata-rata kadar klorin setelah 1 kali pencucian sebesar 0,0176 %, setelah 2 kali pencucian sebesar 0,0111 %, dan setelah 3 kali pencucian sebesar 0,0052 % dengan nilai signifkansi p = 0,03 (p<0,05) pada tingkat kepercayaan 95% yang artinya ada perbedaan yang bermakna antara kadar klorin pada beras berklorin yang dicuci sebanyak 1 kali, 2 kali dan 3 kali.

The height of the maxillary alveolar ridge can be measured using panoramic radiography. The decline occurred because the height of the alveolar ridge undergoes slow physiological resorption due to the absence of mechanical stimulus. The purpose of this research is to know the difference and the average height of the maxillary alveolar ridge in edentulous and dentate women using panoramic radiography. This study is an analytical method with a cross-sectional approach. A total sample of 40 women, edentulous and dentate has been measured. Measurements were made by measuring the distance between the lowest point of the infraorbital ridge and alveolar crest maxilla on the incisor point, right and left premolar, right and left molar. A statistical test is done using independent t-test. The results showed that the average value of a dentate women sample is greater than edentulous. The average value obtained by the dentate sample is greatest in incisor point by 37,57mm± 3,34mm and the smallest at the right molar point by 33,87mm ± 2,81mm. The average value obtained by the edentulous sample is greatest in incisor point by 35,30mm ± 2,79mm and the smallest at the right molar point by 31,84mm ± 3,85mm. It can be concluded that there is a significant difference in the height of the maxillary alveolar ridge on an edentulous sample and dentate, except the right molar teeth. The average height of the maxillary alveolar ridge in an edentulous sample is 33,35mm ± 3,43mm, and the dentate sample is 35,66mm ± 3,21mm.

The purpose of this research aims to determine the effect of adding enzymes (amylase, protease, xylanase) in feed on egg weight and egg yolk diameter in mixed ducks. The experimental animals used were 24 laying ducks. The design used was a completely randomized design (CRD) with 4 treatments and 6 replications. The four treatments were P0 (Control), P1 (6 ducks with Avizym1502®5gram / kg), P2 (6 ducks with Avizym1502® 10gram / kg), and P3 (6 ducks given Avizym1502). ® 15gram / kg). This treatment is carried out once a day for 9 weeks. Before the treatment, the ducks were adapted for a week. After that, the initial egg weight and yolk diameter were measured at week 0, week 6, and week 9. Data obtained from the results of weighing eggs found an average value of P0 (59.1667 ± 3.9200a) g, P1 5gram / kg (56.1667 ± 2.9268a) g, P2 10gram / kg (60.1667 ± 4.9966a) g, and P3 15gram / kg (67.6667 ± 2.7325ᵇ) g. The results of data from examining the diameter of the egg yolk found an average value of P0 (45.03 ± 1.2956a) mm, P1 5gram / kg (44.35 ± 0.7969a) mm, P2 10gram / kg (45.75 ± 1.5694a) mm, and P3 15gram / kg (48.83 ± 0.7394ᵇ) mm. The data obtained were then analyzed using the ANOVA test which statistically showed that there was a significant difference (P <0.05) between egg weight and yolk diameter in mixed ducks treated with enzymes (amylase, protease, xylanase) in the feed.

Aim of the research was to find out and compare individual subsystems of selected types of aggressiveness and individual types of hostility within age categories of learners of sports hockey classes. Research sample consisted of sixth, seventh, eighth and ninth grade boys from primary schools. Age of learners varied from 11 to 14 years. Total sample consisted of 120 learners. The research was it was implemented with the help of a standardized psychological questionnaire B – D – I. In the results we‘re comparing the differences in individual subspecies of aggressive behaviour and also in overall aggressiveness between younger and older learners grade. It turned out that in all of the observed comparisons older learners achieved higher average values of the weighted score than younger. The difference was confirmed also by the nonparametric Mann Whitney U test, which at the unilateral test of 5 % level of demonstrability tells that between younger and older learners there‘s statistically significant difference p = 0.031. Also, any increased value of the resentment didn‘t occur neither among younger learners who achieved the average value of the weighted score 4.19 nor among older learners with the average value of the weighted score 4.81 and therefore there is not statistically significant difference (p = 0.681). Our research revealed that controlling emotions such as aggression is very important. Therefore, it‘s important to pay enough attention to the young athletes and their coaches to prevent any manifestations of aggressiveness from their performers and to encourage them to play fair-play sports.

We have measured with positron emission tomography (PET) the regional distribution of extravascular lung water (EVLW) and hematocrit (HctL) in normal supine dogs. H2(15)O and C15O were used as total lung water (TLW) and intravascular water (IVW) compartment labels, respectively. An additional plasma volume label (68Ga-transferrin) was used to determine regional HctL. EVLW was calculated as the difference between TLW and IVW. In 13 dogs, EVLW was relatively constant along a gravity-dependent vertical gradient, although values in the most anterior regions were statistically less (P less than 0.05) than those in more posterior ones. The average value for EVLW (13 dogs) was 14.4 +/- 2.5 ml H2O/100 ml lung. When EVLW was compared with IVW on a regional basis, the EVLW/IVW ratio decreased significantly in a gravity-dependent direction from 1.95 +/- 0.28 to 0.88 +/- 0.18. In 7 dogs, no significant difference between HctL and systemic hematocrit (average ratio 1.01 +/- 0.08) was found nor was any significant variation of HctL within the lung detected. Thus, in contrast to gravimetric techniques, a hematocrit correction does not appear to be necessary when regional EVLW is studied by PET.

Background: Cast analysis is the measurement of the upper and lower arch in a 3-dimensional occlusal relationship. Howe’s Analysis can be used to observe total tooth material, arch length, and basal arch width. Howe’s Analysis was conducted to analyse abnormalities of both teeth and the jaw to help diagnose and plan dental care. Purpose: To analyse the difference in total tooth material, arch length, basal arch width, and Howe’s Index between male and female undergraduate students from the University of Sumatera Utara who are of Proto-Malay origin. Methods: Ninety-six samples comprised of 48 male and 48 female students were recruited through the purposive sampling method. All samples were undergraduate students at the University of Sumatera Utara and of Proto-Malay origin, aged between 18 to 26, and have met the exclusion and inclusion criteria. We measured the variables using a digital caliper to measure basal arch width and arch length and Moorrees’ method to measure total tooth material. Data were analysed statistically using an independent t-test to compare means between groups (p<0.05). Results: The male samples’ average value of total tooth material 98.49 mm±3.79, arch length 45.55 mm±2.28, basal arch width 41.07 mm±2.83, and Howe’s Index were 41.71 %±2.63, respectively. The female samples had a lower value compared to the male samples, 94.51 mm, 43.27 mm, 36.89 mm, and 39.05 % respectively. There was a significant difference in the total tooth material, arch length, basal arch width, and Howe’s Index between male and female undergraduate students from the University of Sumatera Utara of Proto-Malay origin (p=0.001; p<0.05). Conclusion: The average measurement of total tooth material, arch length, basal arch width, and Howe’s Index was higher in male than female undergraduate students from the University of Sumatera Utara of Proto-Malay origin.
