Growth Performance and Meat Quality of Purebred Bulls Reared under Intensive Production Systems

Background: Growth ability and meat performance are of great economic importance in beef cattle. Therefore, breed comparison experiments are needed to provide valuable information on the suitability of different beef breeds for different production conditions. The aim of the present study was to compare the growth performance and meat quality of young Red Angus, Salers and Limousin bulls. Methods: The material comprised 30 bulls of Red Angus (RA), Salers (SL) and Limousin (LM) breeds. The parameters studied were 210-d bodyweight and daily gains from birth to weaning and to finishing, as well as from weaning to finishing. The finished bulls were slaughtered after 12-hour fasting and post-slaughter evaluation was carried out. The compositions of the samples of meat from the longest dorsal muscle (m. longissimus dorsi) were subjected to basic chemical analysis and sensory analysis. Result: The best results in the period of maternal nursing were obtained by the SL bulls and during intensive fattening, by the LM bulls. The differences existed in the chemical composition and sensory characteristics of meat from the bulls of the studied breeds. The RA breed demonstrated the highest content of intramuscular fat in the longissimus dorsi muscle and received higher scores for sensory characteristics.
The Anti-Biofilm Activity of Oregano Essential Oil Against Dental Plaque-Forming Streptococcus mutans In Vitro and In Vivo

Background: The oral and dental infections that are mainly caused by bacterial biofilms are among the most prevalent human infections worldwide. Objectives: The present study aimed to investigate the in vitro and in vivo inhibitory and anti-biofilm effects of oregano essential oil on the Streptococcus mutans isolates obtained from elementary school students. Methods: This experimental study was conducted on 150 samples collected from the buccal and lingual surfaces of the posterior teeth of elementary school students. S. mutans strains were identified using conventional microbiological and biochemical tests, and biofilm formation was assessed using the microtiter plate assay. The minimum inhibitory concentration (MIC) of the oregano essential oil against the isolates was determined using the broth microdilution method. In addition, the effective constituents of the essential oil were measured via gas chromatography-mass spectroscopy. The in vitro and in vivo anti-biofilm activities of the oregano essential oil were also evaluated using the modified microtiter plate assay and on the tooth surfaces of male NMRI mice, respectively. Results: The frequency of S. mutans was 15.3%, 87% of which were capable of biofilm formation. The MIC of the oregano essential oil was 50 µl/ml against the S. mutans isolates, and 82% of the isolates did not grow at the concentrations of ≥ 512 µl/ml. However, none of the isolates were capable of biofilm formation at the MIC and sub-MIC concentrations of the essential oil. Limonene and myrcene were the most effective constituents of the essential oil. Furthermore, a significant correlation was observed between treatment with the oregano essential oil and biofilm formation by the streptococci isolates (P = 0.05). Conclusions: According to the results, the presence of biofilm and incidence of dental caries were significantly correlated. Moreover, the essential oil of oregano and its main constituents had potent anti-biofilm and antibacterial properties and could be utilized for the production of new plant-based mouthwashes.
INFLUENCE OF NITROGEN AND SULFUR ON YIELD AND SEED QUALITY OF THREE CANOLA CULTIVARS

In order to investigate the effect of nitrogen (N) and sulfur (S) fertilizers on yield and seed quality of three canola cultivars, a factorial based on randomized complete block experiment was conducted during 2005–2006 in Iran. Treatments included four nitrogen rates (0, 75, 150, and 225 kg N ha−1 source of urea), four sulfur rates (0, 100, 200, and 300 kg S ha−1), and three cultivars (‘Pf’, ‘Option-500’, and ‘Hyola-401’). Results indicated cultivar had a significant effect on all studied traits. ‘Option-500’ and ‘Hyola-401’ cultivars had the highest seed yield, protein content, and N:S ratio in seed. The levels of 150 and 220 kg N ha−1 resulted in the maximum protein content. Increasing N levels resulted in N content and decreased the oil content. The interaction effect between S and N levels showed the highest N content in seed was obtained with 300 kg S ha−1 and 225 kg N ha−1.
Hg(II) Adsorption from Aqueous Solutions Using Rice-Husk Ash

Rice-husk ash (RHA) was found to be a good adsorbent for Hg(II) in aqueous solutions. Batch studies indicated that the percent adsorption decreased with increasing initial concentration of Hg(II) and particle size of adsorbent. Twenty g/L of RHA (diameter 37--50 {mu}m) in an aqueous solution of Hg(II) with an initial concentration of 100 mg/L removed 98% of Hg(II). A contact time of 3 hr was found to be optimum. Maximum Hg(II) removal was observed near a pH of 6.0. Adsorption conformed to the Langmuir isotherm. Column experiments indicated that the adsorbed amount of Hg(II) decreased with increasing flow rate and decreasing bed height.
Inelastic Heavy Particle Collisions Involving the Crossing of Potential Energy Curves III: Charge Transfer from Negative Ions of Atomic Hydrogen to Protons

The Landau-Zener formula for the transition probability arising from the pseudo-crossing of potential energy curves is applied to the processes H-(1s)2 + H+ → H(1s) + H(2s or p), H-(1s)2 + H+ → H(1s) + H(3s, p or d) and H(1s) + H(3s, p or d) → H(1s) + H(2s or p) allowance being made for the effect of the orbital degeneracy. Cross sections and rate coefficients are given over a wide range of impact energies and temperatures. The calculations show that the electron transferred in slow encounters between H- and H+ ions falls mainly into the third quantum level. Recombination thus leads to the emission of the first Balmer line. The de-activation process studied is of interest in that it provides an illustration of a type of mechanism whereby electronic energy can readily be converted into translational energy in thermal collisions.
The Effect of Aerobic Exercise with Calorie Restriction Program on Muscle Strength and Aerobic Capacity in Overweight and Obese Women

Background. Few studies have demonstrated that different combinations of calorie restriction (CR) and aerobic exercise training improved aerobic capacity (Redman et al., 2007; Weiss et al., 2017) but did not change muscle strength (Weiss et al., 2017) in adult overweight subjects. However, the effect of six-month program combined of moderate intensity aerobic exercise (150 min/week) and 12.5% of CR on aerobic capacity and muscle strength remains unclear. The aim of the present study was to estimate the effect of a six-month aerobic exercise with CR program on muscle strength and aerobic capacity in middle-aged, overweight and obese women. Methods. Twenty-six overweight and obese sedentary women (36–56 years of age, body mass index (BMI) 25.0–37.5 kg/m2) were recruited and randomly allocated to either control or experimental aerobic exercise with CR program group for six-month period. Changes in handgrip strength, knee extension and flexion strength and aerobic capacity (VO2peak) were measured. Results. Absolute peak VO2 (p < 0.001) and normalized peak VO2 (p = 0.013) significantly increased after the aerobic exercise with CR program. A greater normalized peak VO2 (p < 0.001) was observed after the aerobic exercise and CR intervention compared with the control group. However, no effect was estimated on muscle strength in this study. Conclusions. The combined 6-month aerobic exercise with CR program improved the aerobic capacity in middle-aged, overweight and obese women, but had no effect on isometric and isokinetic strength.
The Influence of Attitude, Interest, Teachers and Peers on Entrepreneurial Career Intention

The purpose of this study is to identify the influence of interest, attitude, teachers and peers towards entrepreneurial career intention of religious secondary school students in Malaysia. The objectives of this study are to identify the level of interest, attitude, teachers’ guidance, peers and behaviour towards students’ entrepreneurial career intention, and to identify the influence of attitude, interest, teachers’ guidance, and peers towards student behaviour on entrepreneurial career intention. This quantitative study uses a survey design involving 328 religious secondary school students in the Sepang district based on multistage sampling starting from stratified random sampling to simple random sampling. The result of the study showed that the domains of attitude, interest, teachers’ guidance, peers and behaviour of entrepreneurial career intention are at a moderately high level. The result of the analysis also revealed that the domain of attitude, interest, teachers’ guidance and peers have significant influence over behaviour on entrepreneurial career intention at 62.6 percent. The domain of interest is the best way to predict the behaviour of students’ entrepreneurial career intention compared to other domains. On the other hand, the domain of attitude is the worst in predicting the behaviour of entrepreneurial career intention. These findings clearly indicate that religious secondary school students have a moderately high tendency to choose entrepreneurship as a career which is driven by interest, teachers’ guidance and peers. The implications of the study also contribute to the applicability of the Theory of Planned Behaviour by Ajzen (1991). Meanwhile, schools need to play a role nurturing entrepreneurial attitudes through formal and informal education continuously.
In-vitro evaluation of remineralization efficiency of chicken eggshell slurry on eroded deciduous enamel

OBJECTIVES: The present study evaluated the re-mineralizing efficiency of CESP on experimentally eroded deciduous tooth enamel by Claritin syrup. MATERIALS AND METHODS: 20 extracted deciduous teeth had been selected and stored in normal saline. Each tooth was cut in a labiolingual direction into 2 halves, one half used as a control and the other used as study. Demineralization of all specimens were done by twice daily immersion in Claritin syrup for ½ an hour for 12 days to form enamel erosion. Remineralization of the study group was done by using CESP slurry twice daily application for 3min. for 10 days. Surface roughness of the specimens was measured by surface profile gauge and microhardness evaluation was done using Vickers tester. Resulted data were tabulated and ana1yzed statistically by t-test with 5% significance 1evel RESULTS: There was statistically significant increase in roughness values after erosion with Claritin syrup (P<0.001). however, it was significantly decreased after remineralization (P=0.01). There was statistically significant decreased mean value of microhardness after erosion with Claritin syrup (P<0.001). however, it was significantly increased after remineralization (P=0.01). CONCLUSION: CESP slurry is a valuable topical treatment in deciduous teeth erosion since it decreased the roughness and increased the microhardness of the enamel surface in-vitro
How the Novelty of Students' Answers in Solving Mathematical Problems?

The impact of giving a thinking freedom opportunity is the diversity of students' answers in solving mathematical problems. The smaller the similarity of students' answers compared to all the answers of students in a class, it means that they have higher creative thinking abilities than other students. It is based on a unique answer compared to the others or in other words it has a higher novelty value than the other answers. The objective of this study was to describe the attainment of the novelty of students' answers in solving mathematical problems. The measurement of novelty of students' answers was carried out on 1,002 students from six junior high schools in Indonesia who had different levels of student's input. The scoring system on the response to the completion of multiple solution tasks was by using the four categories of polytomous in which it is based on the Partial Credit Model (PCM). The data were analyzed by using Quest and Parscale program. The result of this study showed that the students have good skills in solving mathematical problems with new ideas on several items. The items referred to some abilities, such as resolving algebra problems involving money operations, designing a flat shape that has specific characteristics, arranging numbers based on certain patterns, and arranging numbers based on certain patterns. The novelty of this research is that this study considers every answer from students or provides a thinking freedom opportunity for students so that mathematical problems are not absolutely solved with one answer.
Feedstocks for the Future : Biorefinery Production of Chemicals from Renewable Carbon

Converting renewable carbon to chemicals and fuels is experiencing a huge increase in both research and commercial interest. The biorefinery is now a recognized approach for transforming renewable raw materials into separate biobased process streams, and ultimately, marketplace chemicals and fuels. Successful biorefinery operation will fulfill two strategic goals: displacing nonrenewable raw materials (an energy goal, met by production of biofuels) and providing economic incentive to support a robust biorefining industry (an economic goal, met by the production of high value chemicals). These goals are met simultaneously by integrating chemical and fuel production within a single operation. However, a primary barrier to biorefinery development is the relative lack of technology available for the conversion of renewable carbon sources into useful marketplace chemicals and materials. Developing broad based technologies capable of producing families of high value chemicals will provide a significant opportunity for the biorefinery. This introductory paper briefly overviews the biorefinery concept and describes several features of biorefinery operation and technology needs for the production of chemicals from renewable raw materials.
Weak ferromagnetism in cobalt oxalate crystals

Microcrystals of diaquocobalt(II) oxalate have been synthesized by the coprecipitation reaction of aqueous solutions of cobalt(II) bromide and oxalic acid. Chemical analysis and thermal experiments revealed that there is only one phase present. X‐ray powder diffraction studies show that this compound is orthorhombic with space group Cccm. Molar susceptibility versus temperature measurements show the existence of an antiferromagnetic (AF) ordering; however, the hysteresis measured in magnetization measurements as a function of magnetic field reveals a weak ferromagnetic behavior.
Comparison of long-stemmed cementless hemiarthroplasty with proximal femur nail in unstable intertrochanteric femur fractures over 85 years of age

Aim: The most appropriate treatment option for intertrochanteric femoral fractures is still controversial. While there are articles showing that proximal femoral nails are superior to partial prostheses, other studies claim that partial prostheses result in better patient outcomes. We aimed to compare long-stemmed cementless hemiarthroplasty (LFS-BPH) and proximal femur nail (PFN), which are the treatment options applied in unstable intertrochanteric hip fractures in patients over 85 years of age. Methods: The records of 64 patients with unstable intertrochanteric femur fractures who were operated between May 2016 and December 2018 in the Orthopedics and Traumatology Clinic of Maltepe University Medical Faculty Hospital were evaluated. A retrospective cohort study was conducted and 42 patients who met the inclusion criteria were included in the study. The patients were divided into 2 groups as the proximal nail group and the prosthesis group, and evaluated in terms of total hospitalization time, operation time, amount of blood transfusion, time until the patient walked independently, postoperative complications, and Harris hip scores. Results: There were statistically significant differences in favor of the PP group in terms of total length of stay, fully independent mobilization time, deep vein thrombosis and decubitus development in the postoperative period. There was no difference between LFS-BPH and PFN in terms of total hospitalization time, blood transfusion amount, and Harris hip scores in unstable intertrochanteric hip fractures occurring above 85 years of age. Conclusion: LFS-BPH was superior to PFN in terms of operation time, early independent mobilization, reduction of deep vein thrombosis and decubitus development rate in the postoperative period.

Soil nitrogen. III.—Mineralizable nitrogen determined by an incubation technique†

‘Mineralizable-N’ values were determined by incubating at 18° a series of 27 soils of medium and heavy textures at 50% of their moisture-holding capacity for 30 days. Increases in nitrate levels following incubation of soils which had been previously air-dried were, on average, three times as great as increases given by incubating corresponding freshly-sampled soils. In all soils the levels of nitrate and total mineral nitrogen increased appreciably on incubation; corresponding changes in ammonium levels were smaller, were irregular and were not related to other soil characteristics. Increases in nitrate and in total inorganic nitrogen on incubating air-dried soils were approximately related to the initial levels of nitrate present in the soils when they were sampled, and to their percentages of total nitrogen.
Nonvolatile memory devices based on polyimides bearing noncoplanar twisted biphenyl units containing carbazole and triphenylamine side-chain groups

Two novel polyimides, PI(CzBD-BTFBPDA) and PI(TPABD-BTFBPDA), consisting of alternating electron-donating 2,2′-bis[4-(9H-carbazol-9-yl)phenyl]- or 2,2′-bis[4-(diphenylamino)phenyl]-substituted biphenyl moieties and electron-accepting phthalimide moieties were synthesized and characterized. These polyimides are thermally stable with 5% weight loss over 500 °C and the glass transition temperatures of the polyimides were found to be 293 °C. The optical band gaps of PI(CzBD-BTFBPDA) and PI(TPABD-BTFBPDA) were 3.42 and 3.30 eV, respectively, indicating the significance of the linkage groups. The estimated energy levels (HOMO, LUMO) of PI(CzBD-BTFBPDA) and PI(TPABD-BTFBPDA) were (−5.51, −2.10) and (−5.22, −2.02) eV, respectively. Resistive switching devices with the configuration of Al/polymer/ITO were constructed from these polyimides by using the conventional solution coating process. The as-fabricated PI(CzBD-BTFBPDA) film exhibited a nonvolatile bipolar write-once–read-many times (WORM) memory character, whereas devices with the PI(TPABD-BTFBPDA) film showed “write–read–erase” flash type memory capability. The ON/OFF current ratios of the devices were both around 106 in the ambient atmosphere. The mechanisms associated with the memory effect were further elucidated from the density functional theory (DFT) method at the B3LYP level with the 6-31G(d) basis set. The present study suggested that the tunable switching behavior could be achieved through the appropriate design of the donor–acceptor PIs structure to have potential applications for memory devices.
Volatile constituents of different parts (roots, stems and leaves) of Smyrnium olusatrum L.

Smyrnium olusatrum L. is a biennal plant growing in western and southern Europe. Several phytochemical studies have identified flavonoids, phenolic acids and sesquiterpene lactones as main constituents. In this work the root, stem and leaf essential oils of Smyrnium olusatrum L. (Umbelliferae) collected in Urbino (Marche, Italy) were studied by GC and GC-MS. Myrcene (1, 13 and 14%), β-phellandrene (34, 17 and 9%), β-caryophyllene (1, 3 and 12%), furanodiene (19, 8 and 17%), curzerene (13, 6 and 12%), germacrene B (7, 14 and 10%) and germacrone (8, 7 and 8%) were identified as the major components in the root, stem and leaf oils, respectively. SPME analysis of fresh material of the same different organs showed β-myrcene (3, 21 and 36%), β-phellandrene (25, 34 and 12%), β-caryophyllene (1, 7 and 22%) and furanodiene (4, 7 and 7%) as typical components in the headspace of fresh roots, stems and leaves, respectively.
Evaluation Studies to Indicate Wide Diversity in Qualitative Traits of Sesame Germplasm in Madhya Pradesh Region

Sesame (Sesamum indicum L., 2n = 26) is an important ancient oilseed crop adapted to tropical and subtropical areas (Frary et al., 2015). Africa has been considered to be the primary centre of origin of sesame and it spread through West Asia to India, China and Japan, which themselves became secondary centre of origin (Weiss, 1983). The genus Sesamum consists of many species and the most cultivated species is Sesamum indicum L. (Ashri, 1998). Sesame described as the “Queen of oil seed crops” (Deepthi et al., 2014) because it contains high oil (3854%), protein (18-25%), calcium, phosphorous, International Journal of Current Microbiology and Applied Sciences ISSN: 2319-7706 Volume 9 Number 9 (2020) Journal homepage: http://www.ijcmas. com
