Construction and Validation of Newly Developed Triangle Test of Reactive Agility in School Children
Authors: Pavlinović Vladimir 
Published: February 2023

PURPOSE: Agility is described as a rapid whole-body movement with change of velocity or direction in response to the different stimuli. Scientific research identified two independent types of agility performances: pre-planned agility (CODS) and non-planned agility (RAG). CODS represent generic movement patterns. They can mimic the demands of a sport but all of the movements are pre-planned. In CODS there is no response to a stimulus like in RAG where movements are in response to cues such as the movements of the ball or actions of the opposition players. Literature review show lack of studies that assessed CODS and RAG in children, most probably due insufficiency in quality testing protocols. Hence, the purpose of this study was construction and validation of newly developed agility test that measures RAG performances in children. METHODS: For this purpose, the Blaze Pod system (BP) was used. Three lighting pods were mounted on three 50 cm cones in triangle formation with 4,5 meters distance between cones (TRGA). Results were collected via BP app. Four movement patterns were used to test RAG. Start and finish of the tests were conducted with the tap on BP pods. The sample comprised of 80 elementary school children (boys; n=39, age=14.88±0.36 yrs, height=174,3±7,46 cm, mass 67,86±16,78 kg, and girls; n=41, age=14.85±0.31 yrs, height=167.49±5.72 cm, mass=59.34±10.54 kg). Statistical analysis included calculation of normality of distribution, reliability coefficients, correlations and analysis of variance. RESULTS: Tests showed acceptable reliability with CA=0.58, ICC=0.32 for boys and CA=0.78, ICC=0.55 for girls. Inter-item correlations were higher in girls’ sample (r=0.49-0.64) than in boys (r=0.27-0.41). Also, test showed good sensitivity, normal data distribution and good homogeneity with no differences between items (boys; F=0.07, p=0.93; girls; F=0.13, p=0.88). Better reliability of TRAG test for girls is most probably caused by gender morphological differences. Namely, we observed greater standard deviations (SD) of height (BH) and mass (BM) in boys (boys; BH=7.37, BM=16.97; girls; BH=5.68, BM=9.7) and scientific research confirmed negative influence of BM and BH on reactive agility performance. CONCLUSION: Altogether, newly constructed TRGA test seems to be reliable instrument for measuring reactive agility in pubescent boys and girls.

Abstract
This literature research aims to identify rotational dynamics learning problems. The research method used is the System Literature Review (SLR). The results of studying the literature show that a lot of learning research has been carried out on rotational dynamics material. Even though the concept of the material has been conveyed, many students do not understand and fail to apply the concept to solve a problem. This is because the knowledge is still in the form of knowledge and has yet to form a complete knowledge of concepts. Some rotational dynamics learning uses cognitive conflict and analogy. Inappropriate selection of cognitive conflicts and analogies by learners can lead students to make false claims about concepts. Based on the results of the review of the literature study, several recommendations for physics learning models were obtained that could train problem-solving skills with various learning models, scientific approaches, and technological media assistance to support learning activities, especially on rotational dynamics material.
Abstrak
Penelitian literatur ini bertujuan untuk mengidentifikasi permasalahan pembelajaran dinamika rotasi. Metode penelitian yang digunakan adalah System Literature Review (SLR), Hasil belajar literatur menunjukkan banyak penelitian pembelajaran yang telah dilakukan pada materi dinamika rotasi. Meskipun konsep materi telah disampaikan, banyak siswa yang tidak paham dan gagal dalam menerapkan konsep tersebut untuk menyelesaikan suatu permasalahan. Hal ini disebabkan karena ilmu yang dimiliki masih berupa pengetahuan dan belum membentuk ilmu yang utuh tentang konsep. Beberapa pembelajaran dinamika rotasi menggunakan konflik kognitif dan analogi. Pemilihan konflik kognitif dan analogi yang tidak tepat oleh pembelajar dapat membuat siswa memberikan klaim yang salah pada konsep. Berdasarkan hasil kajian studi literatur didapatkan beberapa rekomendasi model pembelajaran fisika yang dapat melatih keterampilan pemecahan masalah dengan berbagai model pembelajaran, pendekatan saintifik, dan bantuan media teknologi untuk menunjang kegiatan pembelajaran terutama pada materi dinamika rotasi.

Published: February 2023

O artigo investiga as transformações na representação da imagem da mulher retratada nas peças publicitárias da Kodak, para suas câmeras domésticas, do final do século XIX aos anos 1980 - período que reflete o apogeu da fotografia analógica. O estudo foi realizado por meio de uma revisão de literatura e levantamento iconográfico, que subsidiaram uma avaliação da evolução da publicidade da empresa e da forma como a mulher é retratada. Os resultados demonstraram uma evolução da percepção sobre o papel social da mulher, que partiu de uma proposta empoderada e “libertária” no início do século passado, seguindo para uma visão que progressivamente transformou a mulher em objeto do produto que a empoderava a partir da década de 1930, até chegar a uma abordagem que reforçava princípios de uma visão estereotipada da mulher, a partir dos anos 1960.
Analysis of urine Raman spectra differences from patients with diabetes mellitus and renal pathologies
Authors: Kavuru Varun , Senger Ryan S. , Robertson John L. , Choudhury Devasmita 
Published: February 2023

Background
Chronic kidney disease (CKD) poses a major public health burden. Diabetes mellitus (DM) is one of the major causes of CKD. In patients with DM, it can be difficult to differentiate diabetic kidney disease (DKD) from other causes of glomerular damage; it should not be assumed that all DM patients with decreased eGFR and/or proteinuria have DKD. Renal biopsy is the standard for definitive diagnosis, but other less invasive methods may provide clinical benefit. As previously reported, Raman spectroscopy of CKD patient urine with statistical and chemometric modeling may provide a novel, non-invasive methodology for discriminating between renal pathologies.

Methods
Urine samples were collected from renal biopsied and non-biopsied patients presenting with CKD secondary to DM and non-diabetic kidney disease. Samples were analyzed by Raman spectroscopy, baselined with the ISREA algorithm, and subjected to chemometric modeling. Leave-one-out cross-validation was used to assess the predictive capabilities of the model.

Results
This proof-of-concept study consisted of 263 samples, including renal biopsied, non-biopsied diabetic and non-diabetic CKD patients, healthy volunteers, and the Surine™ urinalysis control. Urine samples of DKD patients and those with immune-mediated nephropathy (IMN) were distinguished from one another with 82% sensitivity, specificity, positive-predictive value (PPV), and negative-predictive value (NPV). Among urine samples from all biopsied CKD patients, renal neoplasia was identified in urine with 100% sensitivity, specificity, PPV, and NPV, and membranous nephropathy was identified with 66.7% sensitivity, 96.4% specificity, 80.0% PPV, and 93.1% NPV. Finally, DKD was identified among a population of 150 patient urine samples containing biopsy-confirmed DKD, other biopsy-confirmed glomerular pathologies, un-biopsied non-diabetic CKD patients (no DKD), healthy volunteers, and Surine™ with 36.4% sensitivity, 97.8% specificity, 57.1% PPV, and 95.1% NPV. The model was used to screen un-biopsied diabetic CKD patients and identified DKD in more than 8% of this population. IMN in diabetic patients was identified among a similarly sized and diverse population with 83.3% sensitivity, 97.7% specificity, 62.5% PPV, and 99.2% NPV. Finally, IMN in non-diabetic patients was identified with 50.0% sensitivity, 99.4% specificity, 75.0% PPV, and 98.3% NPV.

Conclusions
Raman spectroscopy of urine with chemometric analysis may be able to differentiate between DKD, IMN, and other glomerular diseases. Future work will further characterize CKD stages and glomerular pathology, while assessing and controlling for differences in factors such as comorbidities, disease severity, and other lab parameters.

Published: February 2023

An experiment was conducted to evaluate the effect of black plastic mulch on yield and other associated characters of promising tomato genotypes developed by the National Horticulture Research Centre, Nepal at the Directorate of Agricultural Research, Tarahara, Nepal, during the winter season of 2019. Nine tomato genotypes (HRDTOM 011, HRD 109, HRDTOM 035, HRDTOM 080, HRDTOM 079, HRDTOM 084, HRDTOM 085, HRDTOM 086, and Pusa Ruby as a check) were evaluated in a randomized complete block design (RCBD) with three replications. Genotypes were transplanted 60 cm apart. Analysis of variance showed significant differences for marketable fruits and yield per plant, average fruit weight, total marketable and unmarketable fruit yield, and total fruit yield. Among the tested genotypes, HARDTOM 011 developed the highest (174) number of marketable fruits per plant with the lowest (12.92 g) individual average fruit weight. In contrast, HRDTOM 080 produced the lowest (36) number of marketable fruits per plant with the highest (49.70 g) individual fruit weight. HRD 109 and Pusa Ruby provided the highest (69.74 t ha-1) and the lowest (38.51 t ha-1) marketable fruit yields, respectively. The highest total fruit yield was also obtained from the HRD 109. Similarly, HRDTOM 085 and HRDTOM 035 had the highest total soluble solids and fruit size, respectively. Firmness of the fruit and pH content did not differ among the genotypes. With the same genotypes and location (Tarahara), a 98% greater yield demonstrated that tomato production may be significantly boosted with the use of polyethylene film as a mulching medium in winter tomato production in Nepal.
A Simplified Variant of Chess for which a Short Program Computes a Non-trivial Upper Bound for the Number of Reachable Positions Obtained from 65141475298198504104226577310812726424- 036 Naturally Defined Initial Configurations of Pieces

We simplify the rules of chess. We assume that the initial configuration of pieces is not fixed and satisfies some general conditions. Let I denote the set of all these configurations. By our assumptions, for every C \(\in\) I, after 0 or more moves, the configuration obtained from C and the information who has a move determine the set of all ways of continuing the game i.e. the reachable position. For C \(\in\) I, let R(C) denote the set of all reachable positions obtained from C. A short program shows that card (I) = 65141475298198504104226577310812726424036 and card < 42959232120882551923988994948073848799479217319544.

Mining is an important economic activity globally that is associated with provision of raw materials, industrial growth, employment creation as well as degradation of natural ecosystems and agricultural land. A study was conducted at Base Titanium limited mining company to evaluate the response of maize-green intercrop to farmyard manure and mineral fertilizer in post mined soils. Treatments were sole manure, sole inorganic fertilizer, manure + inorganic fertilizer and unfertilized (control) laid down in randomised complete block design (RCBD) and replicated three times. Data collected included soil nutrients before and after cropping, maize and green grams growth and yield parameters. Obtained data was subjected to analysis of variance using genstat software and means separated using Fisher's LSD. The post mined soils were slightly acidic with optimal levels of Ca, Mg, Mn and Zn, Low levels of P,K, S, B,Cu, CEC, TN and organic matter. After two cropping seasons, S and TN was observed to increase in all treatments, while Ca, Mg, Mn, B and Zn decreased in all treatments. Combined manure and fertilizer application increased average maize plant height, stem circumference and LAI by 38%, 34%, 60% respectively and ears per plant, cob length, grains per cob, grain yield and dry matter weight by 57%, 13%, 47%, 31% and 35% respectively compared to unfertilized plants. Green grams growth and yield in the intercropping system was however not significant after either manure and/or fertilizer application. Although the findings showed that manures and fertilizers application improved nutrient availability in this post mined soils, further research is required to ascertain maize–green gram intercrop, optimal establishment time, spacing, fertilizer and manure rates that can provide optimal intercrop yield as well as soil regeneration.

Published: February 2023

Kernels of cashew (Anacardium occidentale L.) possess an enormous nutritional and technological potential. However, the almond is less consumed and processed by food industries in Côte d’Ivoire. The present study aims to bring added value to cashew kernel. The effect of this cashew almond extract was tested on fermentative activity of two lactic bacteria (Lactobacillus delbrueckii subsp bulgaricus and Streptococcus salivarius subsp thermophilus) specific for yoghurt production.
The study consisted of making seven formulations composed of milk and aqueous extract of cashew almond. Different formulations namely F0, F1, F2, F3, F4, F5 and F6
contained 0%, 5%, 10%, 15%, 20%, 25% and 30% respectively of aqueous extract of cashew almond. Lactic ferment containing the above lactic bacteria was used for fermentation of each formulation.
Effect of aqueous extract from cashew almond on fermentative activity of the two bacteria was carried out by pH, titratable acidity with duration of fermentation to obtain 80 Dornic degrees.
The results showed that the fermentative activity of lactic bacteria tested was improved with formulations with 15% (F3) and 20% (F4). With these two formulations, the acidity of the yogurt reaches 80° D compared to the standard (F0%). The extract therefore seems to stimulate the activity of bacteria at these two rates. Beyond 20% of cashew almond extract, the extract seems to inhibit the activity of lactic acid bacteria. The aqueous extract of cashew almond may play a role in yogurt-like fermented milk technology.

Aims: The conversion of fallow land for the establishment of new orchards is now an alternative to Ivorian coffee growing, which has long been based on the extensive and shifting cultivation system favoured in the past by the abundance of forest reserves.
Study Design: Thus, three fallow soils under coffee trees were studied from a physical-chemical point of view in order to determine their potential for the productivity of new coffee varieties (Coffea canephora Pierre, var. Robusta).
Place and Duration of Study: The study was conducted on the National Centre of Agriculture Research (CNRA) research station at Abengourou, Divo and Man for six months, between June and November.
Methodology: Soil samples and coffee leaves were collected and analyzed in the laboratory according to standard methods to determine their chemical status. Plant growth (height, crown diameter, number of orthotropic, number and length of plagiotropic internodes) was studied in relation to the physical-chemical characteristics of the soil.
Results: The chemical potential of the soils was found to be low overall. Soil deficiency was characterized by low base saturation (less than 30%), organic matter, nitrogen and cation imbalance, as regard as potassium (K), calcium (Ca) and magnesium (Mg). Growth parameters of the coffee trees and their nutritional status were correlated with the physicochemical properties of the soil.
Conclusion: In view of these results, sustainable coffee production requires an improvement in the level of soil fertility under coffee trees.
