Dimensions of the author citation potential
No full textThe citation potential is a measure of the probability of being cited. Obviously, it is different among fields of science because of systematic differences in publication and citation behaviour across disciplines. In the past, the citation potential was studied at journal level considering the average number of references in established groups of journals. In this paper, some characterizations of the author’s scientific research through three different research dimensions are proposed: production (journal papers), impact (journal citations), and reference (bibliographical sources). An empirical application, in a set of 120 randomly selected authors in four subject areas, shows that the ratio between production and impact dimensions is a normalized measure of the citation potential at the level of individual authors.41040
An approach to the author citation potential: measures of scientific performance which are invariant across scientific fields
No full textThe citation potential is a measure of the probability of being cited. Obviously, it is different among fields of science, social science, and humanities because of systematic differences in publication and citation behaviour across disciplines. In the past, the citation potential was studied at journal level considering the average number of references in established groups of journals (for example, the crown indicator is based on the journal subject categories in the Web of Science database). In this paper, some characterizations of the author's scientific research through three different research dimensions are proposed: production (journal papers), impact (journal citations), and reference (bibliographical sources). Then, we propose different measures of the citation potential for authors based on a proportion of these dimensions. An empirical application, in a set of 120 randomly selected highly productive authors from the CSIC Research Centre (Spain) in four subject areas, shows that the ratio between production and impact dimensions is a normalized measure of the citation potential at the level of individual authors. Moreover, this ratio reduces the between-group variance in relation to the within-group variance in a higher proportion than the rest of the indicators analysed. Furthermore, it is consistent with the type of journal impact indicator used. A possible application of this result is in the selection and promotion process within interdisciplinary institutions, since it allows comparisons of authors based on their particular scientific research.149614671,2052,084Q1Q1SCIESSC

Pengaruh Pemberian Minuman Energi Terhadap Kadar Serum Kreatinin Rattus Norvegicus
No full textThe energy drink is a beverage that is increasingly being used by the community with the aim to improve work performance, vitality, and concentration. The energy drink is also suspected to affect kidney function. This study aims to determine whether there is influence of various brands of energy drinks (M1, M2, M3, M4) of the serum creatinine levels in male rats Rattus norvegicus.This is a study with randomized post test only control group design. The study used male rats Rattus norvegicus as many as 25 animals that were divided into 5 groups. The control group, the group P1 = M1 energy drinks, group P2 = M2 energy drinks, group P3 = M3 energy drinks, group P4 = M4 energy drinks. The energy drinks were given as many as 2.5 ml / 200 g weight / day for 1 month. Cardiac blood sampling performed to measure the levels of serum creatinine and then the results were analyzed using One-Way Anova to compare the levels of serum creatinine in each group of this study. Results of One-Way Anova test obtained by sig α = 0.000 which means there is significant difference between the treatment group and the control group. It can be concluded that the administration of energy drinks to the Rattus norvegicus would be altered the kidney function. It is caused by various substances contained in energy drinks such as taurine, sugar, vitamin B, caffeine, and other supplementary materials
Uji Zona Hambat Kombinasi Ekstrak Bawang Putih (Allium sativum) dan Buah Mengkudu (Morinda citrifolia) terhadap Bakteri Escherichia coli
No full textEscherichia coli bacteria is the most common cause of gastroenteritis (diarrhea), urinary tract infections (UTI), food poisoning, and other clinical problems such as neonatal miningitis. Garlic (Allium sativum) and Noni fruit (Morinda citrifolia) are plants that have antimicrobial properties, which can be used against bacteria such as E. Coli. This study was conducted to determine the inhibition zone combination of garlic extract (Allium sativum) and Noni fruit (Morinda citrifolia) against gram negative bacteria E. Coli. The research was conducted at the Laboratory of Microbiology at the Faculty of Medicine, University of Wijaya Kusuma Surabaya, and has been ethically feasible. This study was divided into 4 groups with replications 6 times each; group P0 (sterile distilled water), P1 (50% garlic + 25% noni fruit), P2 (50% garlic + 50% noni fruit), P3 (50% garlic + 75% noni fruit). Data were analyzed using One-way ANOVA test. The analysis results showed that the average diameter of the inhibition zone formed was the largest in group P1 (10.7 mm) and the smallest in group P0 (0 mm), while in P2 (9.89 mm), and P3 (9.77 mm). Based on the analysis test, the higher the concentration of noni fruit given to the extract combination resulted in the smaller diameter of the inhibition zone. This occurs due to the combination of garlic and Noni fruit has an antagonistic effect that depend on bacterial species, temperature, pH, chemical structure, chemical reactions, and concentrations or doses of antimicrobial compounds. The results also showed that there was no significant difference between group P1 and group P2, group P1 with group P3 and group P2 with group P3 showing p-value> 0.005

Variedades geoprosódicas del español la entonación de zonas de Canarias y Cuba.
No full textThis PhD dissertation includes four articles with their impact factor and a series of works carried out during the pre-doctoral period of the author. These papers study different aspects of the intonation in areas from the Canary Islands and Cuba. The majority of compiled studies are based on the methodological guidelines of the AMPER macro project, from the types of corpus studied to the acoustic analysis programs, and even the methods of comparison of the different linguistic areas. However, new techniques for studying data had been added to the original methodology, such as the phonetic or phonological labeling of FO curves, the use of thresholds to test the perceptive relevance of the obtained data or certain strategies to carry out applied studies beyond the traditional description of intonation in different varieties, such as the conduction of diverse types of perceptual tests.
After the General Introduction, where the four assessable works are presented highlighting their thematic unity, in section 1.2. are listed the antecedents and the state of the art of the intonation and prosody studies, taking into account especially those referring to the Cuban and Canarian varieties of Spanish. This section is followed by the Objectives chapter (section 2.), already outlined in the PhD dissertation project, that specifies which of the included papers fulfill all or part of each goal proposed. The description of the Methodology in section 4. is fundamental in a PhD thesis that studies and collects data of multiple parameters in different types of corpus taking into account variables such as gender or level of studies and that includes a great amount of measurements of acoustic parameters and statistical results. At this point we detail the different types of software and techniques used to describe and characterize the intonational patterns obtained from the speakers in the areas under study. In this very section we also describe the tools and procedures to obtain information from the listeners through the conducted perception tests.
Sections 5. and 6. compose the main core of the work and contain the compendium of evaluable papers as they were published, each one preceded by their relevant evaluation, impact factor and databases were they are indexed. In addition,we decided to include other works of consideration that exceed the regulations to be evaluable but that might help to define the solidity of the PhD candidate research activity. This determination is fundamented in the lack of differentiation related to the methodology used or the objectives pursued in these studies against the publications that do fulfill the normative. Subsequently, the general results of the works included are summarized in section 7. considering the objectives proposed in section 2. and relating them to the relevant data obtained in each study presented. Afterwards a discussion (section 8.) of some of the key points of the dissertation is proposed. In this section we tried to confront all the data obtained during the predoctoral period of the author according to different variables and formulate them to illustrate more clearly all the knowledge obtained about the intonation of the Canarian and Cuban speakers in the different types of corpora considered, as well as to evaluate the applicability of these results to different fields.
The display, comparison and review of all the data collected culminates in the final Conclusions (section 9.), which are followed by a list of future works under the same line of research waiting to be completed. The writing of this thesis conclude with the section of acknowledgments, where all the people and entities that have facilitated the research work of the author are referenced. Finally, the bibliography cited in the writing of the dissertation is presented, which is fundamental in this line of research and differs in part from the references contained in each summarized paper

No full textDiabetes mellitus is a metabolic disease characterized by hyperglycemia due to disturbances in insulin secretion, insulin action, or both. The purpose of this study was to analyze the effect of the red dragon fruit juice (Hylocereus polyrhizus) to repair brain organ histopathologic female wistar rats (Rattus norvegicus Wistar strain) with diabetes. This research is a true experiment research with randomized control - group pretest - posttest design and were conducted at the in Vivo Laboratory of Wijaya Kusuma University Surabaya. Twenty five female wistar rats were randomly divided into 5 groups, normal rats group KA (without alloxan induction), diabetic rats group KB (alloxan induction and without given any red dragon fruit juices), treatment group KC (alloxan induction + 2 gr/2,5ml of red dragon fruit juices), treatment group KD (alloxan induction + 4 gr/2,5ml of red dragon fruit juices) and treatment group KE (alloxan induction + 8 gr/2,5ml of red dragon fruit juices). The study was conducted during the period of 16 days with standard feeding adaptations for 7 days. On day 16, all the rats were terminated. Glucose meter is used to measure the levels of blood glucose in rats. Histopathologic observation of rat brain tissue using a microscope Olympus CX21 with Haematoksilin eosin (HE) staining. The results showed the best dose of red dragon fruit juices to decrease blood glucose levels compare between KB and KE with significance p-value = 0.000 (α < 0.05), the blood glucose levels decreased in diabetic rats significantly between KB and KE also decreased in rat brain tissue necrosis with p-value = 0.000 (α <0.05)
ACE I/D and A2350G Polymorphisms are Correlated with Body Mass Index, but Not with Body Weight and Essential Hypertension: Study in Javanese Postmenopausal Women
No full textBackground: Genetics was one of the risk factors for essential hypertension (EH). Research on ACE I/D and A2350G polymorphisms associated with risk factors for hypertension in Indonesia has never been done. Therefore, this study was conducted to analyze the relationship between the genotype and alleles of this gene with EH, body weight, and body mass index (BMI) in Javanese postmenopausal women.Materials and methods: This cross-sectional study involved 69 postmenopausal Javanese women according to several criteria related with hypertension risk factors. The data were obtained from the measurement and questionnaire results, along with Towards Health Card Records. The polymerase chain reaction (PCR) genotyping method used was the restriction fragment length polymorphism and allele-specific.Results: The prevalence of hypertension, prehypertension, and normotension in Javanese postmenopausal women were 0.246, 0.13, and 0.623, respectively. The frequency of BMI classification as underweight, normal, overweight, or obese were 0.029, 0.42, 0.261, and 0.29, respectively. The ACE I/D and A2350G polymorphism variant genotypes and frequencies found were II (0.464), ID (0.522), DD (0.014), and AA (1). Meanwhile, the alleles and their frequencies at ACE I/D gene polymorphism were I (0.725) and D (0.275). The II and ID genotype was mostly found in normotension subjects. The DD genotype was only available in hypertension subjects. There was no association between genotypes and alleles of ACE I/D, hypertension, body weight, and BMI classification (p>0.05). There was an association between these genotypes, alleles, and BMI (p<0.05).Conclusion: ACE I/D polymorphism is susceptible for BMI in Javanese postmenopausal women.Keywords: Javanese postmenopausal, essential hypertension, ACE I/D, ACE A2350
Relationship between Knowledge and Attitude of Healthy Living with Healthy Behavior Patterns in Medical Students
No full textMedical students play an important role in promoting health because they are prospective doctors. Medical students are considered students who have sufficient knowledge and skills about a healthy lifestyle and have a positive attitude towards health. In fact, there are still many medical students who have not implemented a healthy lifestyle. The purpose of this study was to determine the relationship between knowledge and healthy living attitudes with healthy living behavior patterns in FK–UWKS students class 2018. The study used an observational quantitative approach with a cross-sectional study design with 150 respondents taken using the census method (total sampling). analysis technique using spearman rank test. The results showed that the level of knowledge of healthy living was quite high at 78.1% and positive attitudes about healthy living was 54.7%, while having unhealthy behavior patterns was 92.2%. The Spearman rank test showed that there was a relationship between knowledge of healthy living with healthy living behavior patterns p = 0.000 and a healthy lifestyle also had a relationship with healthy lifestyle behaviors p = 0.000. The conclusion of this study is that the pattern of healthy living behavior is not only influenced by knowledge but also by a healthy attitude
