Penelitian tentang pengaruh beberapa perlakuan kombinasi antara media kultur organik berupa vermikompos cair dan media kultur anorganik berupa walne terhadap pertumbuhan Chlorella sp. telah dilakukan. Penelitian ini bertujuan untuk mendapatkan kombinasi media kultur yang terbaik dalam merangsang peningkatan pertumbuhan populasi Chlorella sp.. Jenis penelitian ini adalah eksperimen menggunakan desain percobaan Rancangan Acak Lengkap dengan kombinasi perlakuan faktorial 5 x 5 x 2 (5 konsentrasi perlakuan Medium Walne, 5 konsentrasi perlakuan vermikompos, masing-masing 2 kali ulangan). Chlorella dikultur selama 10 hari. Data dianalisis dengan menggunakan analisis Univariate Analysis of Variance. Hasil penelitian menunjukkan bahwa penggunaan kombinasi media kultur yang berbeda tidak berpengaruh terhadap pertumbuhan Chlorella sp. dan diperoleh kepadatan rata - rata populasi tertinggi, yaitu perlakuan V4W4 pada hari ke-9 dengan jumlah kepadatan populasi 19.530 x 104 sel/ml dan nilai laju pertumbuhan sebesar 1,8 /hari. Hasil uji UNIANOVA menunjukkan tidak adanya pengaruh yang nyata terhadap pertumbuhan  Chlorella sp.Kata Kunci : Vermikompos. Chlorella sp., Walne, Kultur, Kombinasi.

This study employed the multivariate analysis of variance (MANOVA) procedure to examine the influence of students’ sex, age and course of study (department) on mathematics performance in Nalerigu Senior High School of the East Mampurisi district in the Northern of Ghana. The results showed that male students perform better on the average for all the mathematics performance indicators (understanding, knowledge and perception). The MANOVA analysis revealed that students performance in mathematics do not differ across sex (gender) and age group. The results however showed that there was significant difference in performance of mathematics across course of study (department). However, the univariate analysis of variance (ANOVA) results revealed that there was no sex difference in understanding and knowledge of mathematics while significant differences exist in perception of mathematics among male and female students. Further, the study revealed a significant difference in students understanding and knowledge in mathematics and no bias in perception of mathematics among students age. The study therefore recommended that, the Ministry of Education, school managements and other stakeholders such as Non Governmental Organizations should sensitize students to discard beliefs and practices that prohibit effective participation of female students which result to poor performance in mathematics.

This exploratory study investigated the effect of Jungian-oriented group dreamwork on spiritual well-being and the related constructs of purpose in life and social interest. Participants were students at a religiously oriented liberal arts college. An experimental design with matching was employed. Multivariate analysis of variance (MANOVA) followed by univariate analysis of variance (ANOVA) were used. Power and effect size analyses were also employed. The authors are cautious in their interpretation due to small group sizes and the exploratory nature of the research. Nevertheless, the findings suggest some statistical support for the efficacy of a Jungian-oriented dream appreciation group model to enhance spiritual well-being, purpose in life, and social interest.

Knowing the current status of rhythmic gymnasts’ motor abilities allows a valid objective evaluation of their competitive preparedness and facilitate planning of their further development. The main objective was to determine possible differences in motor abilities of rhythmic gymnasts regarding program level they were competing in, their age and national ranking. Three groups of junior rhythmic gymnasts, competing in either A, B, or C level programs, were investigated. Both the multivariate analysis of variance and univariate analysis of variance showed statistically significant differences in the selected motor abilities regarding the program level (flexibility, strength and coordination). A-level rhythmic gymnasts scored best in all the tests assessing flexibility, coordination and strength. The differences in motor abilities between junior rhythmic gymnasts with regard to their national ranking showed no statistical significance, whereas age was statistically significant. The Pearson’s correlation coefficient revealed significant relations between certain motor abilities among rhythmic gymnasts in A, B and C level programs. The higher the level of a program, the higher the correlatives, and vice versa. Two tests had the largest contribution to the success achieved in the competition: the figure of eight with bending and forward bent on the bench. The scientific value of the proposed research is aimed at better planning, programming and control of training process in rhythmic gymnastics.

Background/Aim. The main role of physical education is health and educational practices of cadets and all-round personality development. Instruction executing is successful only when the set requirements are realized. The aim of this study was to evaluate the effectiveness of physical education in order to rise physical capabilities of the Military Academy cadets during a 4-year education. Methods. The study was conducted in the Military Academy, Belgrade. A total of 120 cadets who at the beginning of the study were 19 years ? 6 months and at the end 23 years ? 6 months were included in this study. The study used the following tests for verification and assessment of physical fitness: pull-ups, lifting the trunk from the ground, standing long jump seats, running at 1,600 m and overcoming the infantry obstacles. The data were analyzed using statistical programs to calculate the central and dispersion parameters. The difference in the achieved results in the individual variables were evaluated by the univariate analysis of variance (ANOVA), while the differences in the system variables by region were identified by the multivariate analysis of variance (MANOVA) and discriminant analysis. The group membership was determined using profile analysis. Results. There were statistically significant differences in all the tests to evaluate the effectiveness of physical education during a 4-year study, except in the standing long jump test. The best average results in motor capabilities tests, were achieved after two years of study, while in the endurance tests showed the best results achieved at the end of a 4-years studying. Conclusion. The results of overcoming specific tests for the physical abilities of the Military Academy cadets show that the physical education curriculum only slightly improves the development of physical skills of cadets during a 4-year study. The existing program shows the best results in the pull-ups test of the ground troops, and the worst in the multiple motor control tests (endurance, strength and speed).

A sample of 111 first-grade children was partitioned into 4 categories, where the categorization was determined by an ability to make quantitative comparisons and IQ. 6 problems of each of 8 problem types were presented to each child in a randomized sequence. Approximately one-half of the children in each category were randomly assigned to 1 of 2 levels of Problem Conditions. A multivariate analysis of variance indicated that IQ was not significant. Problem Conditions was significant (p<.01p<.01). Univariate analysis indicated a significant interaction (p<.05p<.05) due to Quantitative Comparisons and Problem Conditions for 1 problem type; significant main effects (p<.01p<.01) due to Problem Conditions for the remaining 7 problem types; and a significant (p<.05p<.05) main effect due to Quantitative Comparisons for 1 of the remaining 7 problem types.

Two new species of the lineomaculatus clade of the Liolaemus lineomaculatus section are described from southern Patagonia in Argentina. Liolaemus morandae sp. nov. is found in S Chubut province and Liolaemus avilae sp. nov. inhabits NW Santa Cruz province. Several tests were performed to diagnose these new species as distinct lineages. Univariate analysis of variance (ANOVA), principal component analysis (PCA), discriminant function analysis (DFA), non-parametric multivariate analysis of variance (NPMANOVA), as well as a genetic characterization through molecular analysis of variance (AMOVA) were performed; genetic distances between described and these new species are reported. The new Liolaemus species differ from other members of the lineomaculatus group in morphometric, meristic, qualitative and genetic characters; moreover they inhabit different phytogeographical provinces and districts. With these descriptions, the number of species now recognized in the lineomaculatus section is twenty one (including one more description that is in press).
