Authors: Susilawati Susilawati , Doyan Aris
Published: July 2023

This study aims to determine the effect of problem based learning models assisted by PhET simulations on student learning outcomes in wave material. This research is a type of quasi-experimental research with nonequivalent control group design. The population in this study were all students of class XI MAN 1 Mataram. The research samples were students in class XI MIPA 3 with a total of 31 people as the control class and students in class XI MIPA 4 with a total of 29 students as the experimental class. The test instrument used is in the form of multiple choice questions. The results of the analysis show that the average score of physics learning outcomes in the psychomotor domain in the experimental class is 3.43, while for the control class the average value is 3.06. Analysis of physics learning outcomes in the affective domain of the experimental class was 3.34, while for the control class the average value was 3.13. The results of the questionnaire analysis of student responses in the experimental class obtained an average of 63.63. The results of testing the hypothesis using the t-test obtained a tcount of 6.45 and a ttable of 2.00. Thus the value of tcount is greater than ttable then Ha is accepted and H0 is rejected. This means that there is an influence of the problem-based learning model assisted by PhET simulations on student learning outcomes in wave material.

To study the effect of three levels of nitrogen (N) (0.40 and 80 g/m²) and three levels of phosphorus (P) (0.150 and 300 g/m²) involving four varieties of tuberose, viz single, double, semidouble and variegated, experiments were conducted in 1990-91 and 1991-92. Application of highest dose of P contributed maximum plant height, while, N did not respond to this character. N and P applications were also not found effective for other vegetative attributes as compared to interaction application. Interaction influence of these nutrients in these strains was found to be very effective for almost all the growth characters except diameter of leaf. But the combined application of both the nutrients was not beneficial in the present set of material.

The correlation studies in sesame revealed that the traits viz., number of capsules on main stem as well as on branches, leaf area and shoot weight showed positive correlation with yield and an intensive selection for these traits in positive side will improve the yield automatically. When correlation among different traits were further partitioned, four traits viz.,) shoot weight, number of capsules on main stem, number of capsules on the branches and leaf area, had both direct positive effect as well as indirect influence via each other for the expression of yield. Hence, selection pressure applied on these traits individually or simultaneously will increase the productivity in sesame.

A population of 15 genotypes of grain sorghum varieties exhibited significant genotypic variation for ten characters selected in and around the ear head of the crop. The magnitude of PCV and GC were more or less equivalent for number of whorls per ear head, rachis per ear head, number of grains per ear head, 1000 grain weight and grain yield. These characters were less affected by environmental fluctuations whereas the character number of grain per earhead showed least or not affected by environmental changes. Seed density was remarkably masked by environmental components. Four among ten characters registered high values of heritability and genetic advance indicating the presence of addition genc effects. The grain yield showed no correlation with most of the component characters except with 1000 seed weight and number of grains per rachis which may be due to the elimination effects of one or other characters contributing for grain yield. This suggests that it is a complex character in the sorghum. Path analysis indicated that 1000 seed weight and number of grains per rachis are the prime characters for the improvement of genotypes.

Five rust resistant and four rust susceptible groundnut (Arachis hypogaca L.) genotypes were crossed in all possible combinations to study the nature of combining ability and gene action involved for 13 quantitative traits. Combining ability analysis showed the importance of GCA variance alone for number of primary branches and days to 50 per cent flowering while for the remaining characters, both the GCA and SCA variances were important with predominance of GCA indicating the scope for exploiting the available additive components. The rust resistant Virginia genotypes VG 78 and CS 31 were the best general combiners for yield and yield components while the two Spanish types CO 1 and VRI 1 for carliness, number of mature pods per plant and harvest index and VRI 1 for oil content also. Inter-subspecific hybridisation between the Spanish and Virginia genotypes followed by intermating is advocated to exploit both the additive and non-additive components.

Ten sweet pearl millet genotypes were crossed in a partial diallel and the resultant 45 hybrids were evaluated for their combining ability for 10 different fodder attributes. The results indicated that juice volume, leaf-stem ratio, number of tillers and plant height were largely under the influence of additive genes. The characters, green fodder yield, dry matter yield, days to 50 per cent flowering, number of leaves, leaf length and crude protein were influenced equally by both additive and dominant genes. Among the parents, Co-7, ICMV 87111 and TNSC-1 were the best general combiners for green fodder yield, and dry matter yield. AFB-48-1 was found to be the best general combiner for crude protein. Among the hybrids AFB 48-1 x PCB 87-24, AFB 48-1 x HC-4 and APFB 2x Co-7 were found to be the best specific combiners for green and dry fodder yield.

Eighteen genotypes of panivaragu - prosomillet (Panicum miliaceum: L) were evaluated for dry matter production and harvest index in relation to grain yield. High GGV, heritability and genetic advance as percentage of mean observed for harvest index indicated that harvest index may be governed by additive genes. All the other characters which exhibited medium heritability and medium genetic advance may be governed partially by additive genes. Grain yield was positively associated with total biomass, earhead weight and harvest index. Earhead weight is also positively correlated with total biomass, root weight and harvest index. Though selection for improvement of grain yield is possible through positively associating yield contributing characters, they are mostly affected by environment. So, selection of genotypes for the improvement of grain yield through harvest index is appropriate in the present materials since harvest index is not much influenced by environment and also grain yield is positively correlated with harvest index.

The Effect of irrigation regimes, methods of irrigation and coir- pith application to soil wasstudied through a field experiment conducted at the Agricultural College and Research Insitutute, Madurai during 1984 and 1985. The results revealed that higher soil moisture regime of 0.90 IW/CPE ratio recorded higher cane yield than alternate furrow method. Under alternate furrow method of irrigation, the moisture contribution from irrigated furrow to unirrigated furrow was less resulting in low cane -yield. Application of coir pith at 15t ha¹ was found to be optimum. However, under contraints of irrigation water, imigation can be scheduled at 0.75 IW/ CPE ratio adopting alternate furrow method of irrigation coupled with an application of coir pith at 15 t ha -1 for achieving a reasonable cane yield in sugarcane.

Pharmacokinetic Interaction Between Favipiravir and Amlodipine in Hypertensive Local Rabbits (Oryctolagus cuniculus)
Authors: I Al-ameedi Ali , M AL-Rekabi Falah
Published: July 2023

In the treatment of COVID-19, the antiviral medication Favipiravir has proven to be quite successful. Its metabolism is mediated by the enzymes aldehyde oxidase (AO) and xanthine oxidase (XO). This research investigated the potential drug-drug interaction betweenfavipiravir and amlodipine in hypertensive rabbits. Twenty local adult male rabbits (aged between 10 and 12 months and weighing between 2 and 2.5 kg) were induced with hypertension by 20 mg/kg BW of desoxycorticosterone acetate subcutaneously for three weeks and then divided randomly into two groups of ten. The first group received a single oral dose of 40 mg/kg BW of favipiravir, while the second group received 5 mg/kg of amlodipine orally for 14 consecutive days to inhibit AO before receiving a single oral dose of 40 mg/kg BW of favipiravir. Blood samples were collected from the marginal ear vein at 15, 30, 45 min, and 1, 2, 4, 8, 12, 24, 48, 36, 48, and 72 h. High-performance liquid chromatography (HPLC) was used to determine the concentration of favipiravir in the plasma. The results showed that co-administration of amlodipine prolonged the time taken for favipiravir (Tmax) to reach maximum plasma concentration (Cmax) and decreased its elimination half-life, while increasing the area under the curve (AUC). Amlodipine also prolonged the elimination of favipiravir by reducing the clearance per unit time (Cl/f). Additionally, hypertension potentiated the effect of amlodipine on the absorption, distribution, metabolism, and excretion of favipiravir. In conclusion, concomitant use of favipiravir with other drugs that affect AO enzyme activity may alter the pharmacokinetic profile of the drug. Therefore, adjusting the dose of favipiravir administered to hypertensive patients receiving amlodipine is recommended.

The paradox of aggression in adolescent depression: A systematic review
Authors: S. Venkatesan  , Yashodhara-Kumar G.Y  , Iyer Kamalam Gopalakrishnan
Published: July 2023

Teenagers who have aggressive or irrational outbursts could be hiding depression. Overt depression is evident when it manifests as melancholy, weeping fits, low self-esteem, loss of interest, and similar symptoms. Persistent actions like aggression, impatience, use of force, attack, hurt, and violence should raise the possibility of sadness masquerading as hostility. At times, adolescent depression can manifest as inner-directed behaviors like deliberate self-harm, compulsive stealing and fire-setting, chronic abdominal pain without biological cause, and anorexia-bulimia. If outer-directed, at an extreme, they can even show up as homicides, assaults, and robberies. There are also active and passive forms of aggression. This narrative review is exclusively concerned with adolescent depression that presents as aggression and is based on secondary sources of 83 published studies in indexed journals. This compilation, prepared based on PRISMA guidelines, is presented and discussed on themes, timelines, and format of the publications along with their implications for contemporary clinical practice and directions for future research.
Drag and heat transfer effect of grooved hydrophobic bluff bodies
Authors: Annalisa Mazzanti  , Domenica Costa  , Santo Caruso
Published: July 2023

This research delves into an examination of the potential reduction in friction drag within turbulent channel flow through the implementation of superhydrophobic surfaces. The focus lies on considering the effect of the hydrophobic surface as a slip boundary condition along the wall. Consequently, this newly introduced boundary condition becomes an integral part of the Large Eddy Simulation (LES) equations. The projected outcome suggests a substantial drag reduction of approximately 15% at Re = 5000-8000 and enhanced heat transfer by 20%, aligning harmoniously with the findings derived from Direct Numerical Simulation (DNS). Significantly, this discovery holds implications regarding the modification of near-wall turbulence structures through the introduction of streamwise slip velocity. Moreover, it becomes evident that the turbulence structure experiences a discernible transformation when the slip length exceeds a specific threshold value.
Trent’anni fa i risultati del DCCT: cosa significarono allora e cosa rappresentano oggi
Authors: B. Bolli Geremia , Porcellati Francesca , Lucidi Paola , G. Fanelli Carmine
Published: July 2023

The DCCT (Diabetes Control Complication Trials) has conclusively demonstrated in 1993 that good glycaemic control prevents the micro-angiopathy caused by chronic hyperglycaemia in T1DM. The subsequent follow-up study EDIC (Epidemiology of Diabetes Interventions and Complications) has demonstrated similar results for macro-angiopathy. Taken together, DCCT and EDIC strongly indicate the need for aggressive treatment of T1DM with intensive therapy to target near-normoglycaemia since clinical onset of T1DM to prevent long-term micro- and macro-vascular complications. Today and in the years to come, this message remains and will remain as fundamental as it was 30 years ago.
Ruolo dell’insulina e del recettore insulinico nel tessuto adiposo
Authors: Annamaria Genchi Valentina , Lauriola Celeste , Cignarelli Angelo , Giorgino Francesco
Published: July 2023

Insulin regulates whole-body energy and lipid metabolism by activating the insulin receptor (INSR) consisting in two isoforms: INSR-A expressed in less-differentiated cells with prominent mitogenic effect; INSR-B mostly expressed in adult tissues with pronounced metabolic properties. It is well known that tissue-specific variation in INSR-A/INSR-B ratio may favour the development of metabolic abnormalities. Herein, we examine the role of insulin/INSR signalling in the regulation of several aspects of adipose tissue physiology and the effects of insulin mimetics on adiposity.
Effect of Shallow Cryogenıc Heat Treatment on Metal Inert Gas Weldıng Zone of S 355 J2 Steel
Authors:   Haliç University, Özdemir Zafer
Published: July 2023

Metal inert gas welding (MIG) is generally conducted in the pressure vessel industry due to its high quality and easy automation. S355 J2 steel is used widely in this industry for its proper welding properties. To carry out and obtain high melting efficiency for satisfactory mechanical properties according to welding parameters, sometimes heat treatment is applied to materials, but generally it is not common in welding industry. In this study the effect of conventional heat treatment and shallow cryogenic heat treatment effects to the mechanical properties of welding zone of S 355 J2 steel welded with MIG is investigated. The charpy impact tests have been carried out. The welding plate is prepared according to this purpose and it is cut for impact test samples 10 X 10 x 55 mm. Totally 30 samples are prepared for 5 processes. Process 1: 6 samples for without heat treatment. Process 2: 6 samples for normalization-quenching in water. Process 3: 6 samples for normalization-quenching-tempering. Process:4 6 samples for normalization-shallow cryogenic treatment. Process 5: 6 samples for normalization-shallow cryogenic treatment-tempering. Notch of impact test samples are prepared just in the middle of the welding zone (2 sample for each process) , HAZ (2 sample for each process) and basemetal (2 sample for each process). The hardness values are taken from base metal, heat affected zone and welding area respectively. Hardness values and impact test results are compared. As a result, generally, it has been observed that shallow cryogenic heat treatment have a remarkable effect on toughness, despite a little decrease in hardness. The toughness of welding zone is increased approximately %40 and HAZ % 5 after cryogenic heat treatment. The hardness of WZ is increased approximately % 5 after cryogenic heat treatment, no significant change is observed in HAZ.

Weld imperfections are likely to arise during any welding process. Due to the enormous number of joints that could result in weld defects, welding process faults could happen. Repair procedures are required to address welding defects. Multiple repairs are required if welding mistakes are made repeatedly. The duplex material used in this study is SA 240 TP 904L. By altering the repair procedure treatment 1x, 3x, 5x, and without repair, the welding process is carried out utilizing the SMAW method and E309L filler. Microstructure testing, ferrite content testing, and 3-electrode cell corrosion are the test techniques used. The relationship between the corrosion rate and the amount of ferrite content was deduced from the test data. The corrosion rate increases as the ferrite content rises due to several repairs.

The packaging station is one of the stations needed to produce the product. The workers in this station are still doing the process manually. The packaging station has several processes, namely the weighing process, the sewing process, and the moving process of the finished product by manually lofting the sack from the sewing machine to the pallet. The moving process has three activities holding, lifting, and moving. Workers who work manually often complain of pain felt while working, so they are at risk of experiencing musculoskeletal disorders. Accordingly, it is important to analyse the work posture to determine whether improvements must be made. The Rapid Entire Body Map (REBA) analyses the work position. Analysis of work posture is moving the product. The REBA method's posture assessment results are 8 for holding, 9 for lifting, and 10 for moving. From the results, it can be categorized as a high-risk level, and immediate improvements are needed. The improvements were made by designing a conveyor from the sewing machine to the pallet using the Anthropometric method with dimensions of 100cm, width of 65cm, and height of 113cm.

The purpose of this research is to determine the velocity characteristics of fluid (fuel) flow in a pipe surrounded by a minimal magnetic (electromagnetic) field strength by using computational fluid dynamics simulations. For a more detailed discussion, Magnetohydrodynamics (MHD) theory is used, which is a branch of science that studies fluid flow that can conduct electric current due to the influence of a magnetic (electromagnet) field. The fuel used is B0, B10, B20 and B30. The magnitude of the electromagnetic field used is 0.15 Tesla. the result is that the flow rate of B0 fuel has decreased by 0.623%. B10 fell to 0.41%. The B20 was down 0.618% and the B30 was down 0.648%. Thus the magnetic field strength of 0.15 Tesla is able to change the speed of the fuel flow even if only slightly. This information is needed as a basis for the development that the magnetic field is able to change the value of the flow velocity, this will provide information related to improving the quality of combustion and fuel savings in the future.
