SPECIAL ISSUE: Cosmological transitions with changes in the signature of the metric

It is conjectured that there exist states of the physical continuum which include regions with different signatures of the metric and that the observed Universe and an infinite number of other Universes arose as a result of quantum transitions with a change in the signature of the metric. The Lagrangian in such a theory must satisfy conditions of non-negativity in the regions with even signature. Signature here means the number of time coordinates. The induced gravitational Lagrangian in a conformally invariant theory of Kaluza-Klein type evidently satisfies this requirement and leads to effective equations of the gravitational theory of macroscopic space identical to the equations of the general theory of relativity. It is suggested that in our Universe there exist in addition to the observable (macroscopic) time dimension two or some other even number of compactified time dimensions. It is suggested that the formation of a Euclidean region in the center of a black hole or in the cosmological contraction of the Universe (if it is predetermined by the dynamics) is a possible outcome of gravitational collapse.
Generalized geometry applied to 4d-supergravity

Generalized complex geometry is an example of a powerful formalism to attempt the construction of a language adequate to string theory. With the remarkable property of unifying symplectic and complex manifolds as special cases of a broader structure it is proving to be the right tool to use when trying to describe T-duality. The key idea was to look at both geometries as operations in the direct sum of tangent and cotangent bundle as opposed to the usual approach, where only the tangent spaces are relevant. In this thesis we will be interested in developing a formalism drinking from these ideas but for a toy model of eleven dimensional M-theory: three-form supergravity as introduced by Ovrut and Waldram.
The Prevalence of Internet Addiction and Associated Factors among School-Going Adolescents in Ahmedabad

Background: The Internet is an integral part of modern life, and for the vast majority of Internet users, its benefits far outweigh the adverse consequences secondary to excessive use. Increasing internet use among adolescents is also likely to pose a major public health concern that is internet addiction (IA). Aim: To assess the prevalence of IA among school? going adolescents and the factors associated with IA. Methodology: A cross? sectional study was carried out to survey adolescents studying in 8th to 10th standard of three schools of Ahmedabad. The sample size was calculated 384 by using the formula (n = Z2pq/d2). Information regarding sociodemography and various patterns of internet use were obtained by using survey forms. Young’s IA test (IAT) Questionnaire was used to screen for IA. Results : The prevalence of Internet Addiction (IA) was 67.5%, 27% and 5.5% with normal (IAT < 50), moderate (IAT 50-79) and severe addiction (IAT 80-100) respectively. Age, male gender, owning a personal device, hours of internet use per day, use of smartphones, permanent login status, online shopping, watching movies, online gaming, searching information online were found to be significantly associated with severity of IA. Conclusion: Our study revealed a relatively high prevalence of internet addiction among younger participants and that requires awareness and intervention towards risk factors of internet addiction.
Effect of methanolic extract of sphaeranthus amaranthoides (MESA) on nicotine-induced Serum testosterone levels in adult Wistar albino rats

Background: Infertility is one of the most common health issues. Infertility in men occurs when sperms cannot fertilize eggs. Infertility can be caused by a variety of factors, medical conditions, and medications. Testicular insufficiency results when a normal individual is exposed to some toxic substances and lifestyle disorders. Smoking cigarette is one such condition that affects male reproductive system. Nicotine is the main metabolite of cigarette smoke. Testicular damages are always related with hormonal changes. Objectives: The aim of this study is to evaluate the effects of Methanolic extract of sphaeranthus amaranthoides with regard to Changes in serum testosterone levels caused as a result of nicotine -induced testicular damage. Methods: Four equal groups( 24nos) of male wistar albino rats were randomly assigned to control, nicotine and methanol extract of sphaeranthus amaranthoides with doses1(250 mg/kg BW) and 2 (500 mg/kg BW), respectively. The animals were treated for forty-eight days. The blood samples were collected at the interval of 20, 40, and 48 days, to evaluate the serum testosterone levels. Results: Nicotine reduced Serum testosterone level (p < 0.001). When treated along with Methanolic extract of sphaeranthus amaranthoides treatment significantly increased blood testosterone level (p<0.001).
Exploring the Influence of the Parameters’ Relationship between Reliability and Maintainability for Offshore Wind Farm Engineering

The two main research goals of this study are to develop a relationship diagram between the parameters of reliability and maintainability and to investigate the impact of reliability and maintenance on engineering design costs. In this study, we use the theory of reliability and maintainability parameters to derive the relationship between the parameters using block diagrams. Compared with onshore wind farms, offshore wind farms have higher reliability requirements, but the maintenance degree of offshore wind farms is lower due to environmental factors. This study proposes an important concept of reliability and maintenance for value engineering, which can help system design engineers and project engineers integrate reliability concerns in the design phase and operation and maintenance phase.
Robust consensus of heterogeneous multiagent systems with switching topologies: A time‐delay case

The robust leader‐following consensus of heterogeneous multiagent systems under switching communication topologies is investigated in this paper. Especially, the input delay is considered in each follower. In order to access the information of leader through time‐varying communication, a type of distributed dynamic compensator is proposed for every follower firstly, which get rid of the dependence on the global spectrum information and is proved that it can be viewed as a asymptotic observer of the leader. Then combined with the internal model principle, two types of distributed control law are proposed based on the compensator. By applying the truncated predictor feedback scheme to synthesize the closed‐loop systems, it is proved that the consensus can be achieved by both of the control laws despite the existence of the input delay and the plant parameters perturbations. Finally, numerical simulations are illustrated to demonstrate the results.
Toward modeling thrombosis and thromboembolism in laminar and turbulent flow regimes

Thrombosis and thromboembolism are deadly risk factors in blood‐contacting biomedical devices, and in‐silico models of thrombosis are attractive tools to understand the mechanics of these processes, though the simulation of thromboembolism remains underdeveloped. The purpose of this study is to modify an existing computational thrombosis model to allow for thromboembolism and to investigate the behavior of the modified model at a range of flow rates. The new and existing models are observed to lead to similar predictions of thrombosis in a canonical backward‐facing step geometry across flow rates, and neither model predicts thrombosis in a turbulent flow. Simulations are performed by increasing flow rates in the case of a clot formed at lower flow to induce embolization. While embolization is observed, most of the clot breakdown is by shear rather than by breakup and subsequent transport of clotted material, and further work is required in the formulation and validation of embolization. This model provides a framework to further investigate thromboembolization.
Ethical considerations of telehealth: Access, inequity, trust, and overuse

In the U.S. healthcare system, telehealth is increasingly present and demands ethical assessment. On the one hand, telehealth increases access to healthcare services for some at-risk populations (e.g., people suffering from mental illness and addictions) and in specific contexts (e.g., rural). On the other hand, telehealth widens the digital divide and can lead to overuse of services. Furthermore, because it is still unclear how telehealth influences trust between patients and primary care clinicians, connecting relationship science and human communication research can inform critical reasoning. Finally, healthcare policy is advancing toward the wide adoption of telehealth. Hence, it is urgent to address these ethical issues and invest in further research.
Lamotrigine and Memory Impairment Associated with Generalized Seizures: A Study on Maximal Electroshock Seizure Model of Mice

Memory impairment (MI) a category of cognitive disturbance is a common annoyance in epileptic patients. The disease remedy is an anti-epileptic drug (AED) treatment which has been at certain cases found to complicate this issue due its CNS side effects. Here we aim to assess the degree of memory impairment associated with generalized seizures and the effect of lamotrigine (LAM) at normal and reduced dose on this unpleasant effect. Standard phenytoin (PHT) was used for comparing the effect of LAM on MI associated with generalized seizures. Albino mice (n=36) of either sex were treated for a period of 29 days with the drug alone and further combined with levetiracetam (LEV) for 35 days. Assessment of anti-epileptic activity by maximal electroshock on every 7 th day and memory impairment activity by Morris water maze (MWM) task on every 8 th day for a 64 days treatment schedule was performed. Abolishment of extensor phase, escape latency time (ELT) and time spent in target quadrant (TSTQ) were the parameters observed. Mechanistic studies involved the determination of acetylcholiesterase (AChE) and glutamate levels in brain homogenates. LAM significantly exhibited a lesser degree of memory impairment which was observed by MWM test and decreased AChE and glutamate levels when compared to phenytoin treated group. Combination of LEV was an approach implemented to correct the aggravating effect of MI by the AED, decreased the same significantly and additionally exhibited synergism in anti-epileptic activity. These outcomes could hence aid in the incorporation of LAM and LEV as poly-therapeutic agents and as an alternative to phenytoin to reduce the patient non-compliance to epilepsy treatment. However the need for in-depth research is crucial for the conclusion to be effective for incorporation into the worldly scenario.
Psychometric Evaluation of the Generalized Problematic Internet Use Scale 2 in an Indonesian Adolescents’ Sample

: Internet users in Indonesia has increase and become challenged associated with symptoms of internet addiction. Teenagers are the most vulnerable group to have Problematic Internet Use (PIU). This study’s main purpose was to examine the psychometric properties of Generalized Problematic Internet Use Scale 2 (GPIUS 2) in an Indonesian adolescents’ sample. The second aim was to investigate the concurrent validity of the Indonesian version to provide evidence for the validity. The study involved a cross-sectional online survey design with 300 adolescents with an age range of 15-18 years (M = 16; SD = 0.94) of which 70.7% (n = 202) were female adolescents. GPUIS2 contains fifteen Likert-type items rated on an 8-point scale which modified into 5-point Likert from “strongly disagree” to strongly agree. ” GPIUS 2 was adapted to Bahasa Indonesia using backward translation techniques. Structural Equation Modeling (SEM) (i.e., Confirmatory Factor Analysis (CFA) was performed to evaluate the psychometric properties of the GPIUS-2. Internal consistency for both the subscales and the total scale had been assessed by calculating the alpha coefficients. The results provide support for the original factorial structure similar by Caplan (2010) with five factor solution models. Results indicated that the model fit the data well, χ2 = 230.697; d.f = 80; p < 0.001; CFI = 0.91; TLI = 0.92; RMSEA = 0.07. The study also found good reliability for the global scale (α = 0.83). Further research needs to explore models with relevant psychological constructs in revealing problematic internet behavior in adolescents. Longitudinal studies, and in-depth interviews are also very important for future studies to present more comprehensive data. Expanding the age of respondents to obtain comparisons between generations is something that can be done considering Internet penetration has entered all layers of the age generation.
ON WEAK CONVERGENCE OF THE PARTIAL SUMS PROCESSES OF THE LEAST SQUARES RESIDUALS OF MULTIVARIATE SPATIAL REGRESSION

A weak convergence of the sequence of partial sums processes of theresiduals (PSPR) when the observations are obtained from a multivariate spatiallinear regression model (SLRM) is established. The result is then applied in constructingthe rejection region of an asymptotic test of hypothesis based on a type ofCramer-von Mises functional of the PSPR. When the null hypothesis is true, we getthe limit process as a projection of the multivariate Brownian sheet, whereas underthe alternative it is given by a signal plus multivariate noise model. Examples ofthe limit process under the null hypothesis are also studied. DOI : http://dx.doi. org/10.22342/jims.20. 2.183. 77-94
Triangulating the New Frontier of Health Geo-Data: Assessing Tick-Borne Disease Risk as an Occupational Hazard among Vulnerable Populations

Determining interventions to combat disease often requires complex analyses of spatial-temporal data to improve health outcomes. For some vulnerable populations, obtaining sufficient data for related analyses is especially difficult, thus exacerbating related healthcare, research, and public health efforts. In the United States (U.S.), migrant and seasonal workers are especially affected in this regard, with data on health interventions and outcomes largely absent from official sources. In response, this study offers a multi-modal approach that involves triangulating geographically specified health data that incorporate reports on canine tick species, Lyme disease (LD) incidence, and patient symptom severity indicating potential subsequent disease burden. Spatial alignment of data at the U.S. county level was used to reveal and better understand tick-borne disease (TBD) incidence and risk among the identified populations. Survey data from migrant and seasonal workers in Texas were employed to determine TBD risk based on symptoms, occupations, and locations. Respondents who were found to have a higher likelihood of a TBD were also considerably more likely to report the most common symptoms of LD and other TBDs on the Horowitz Multiple Systemic Infectious Disease Syndrome Questionnaire. Those in the highly likely scoring group also reported more poor health and mental health days. Overall, a notable number of respondents (22%) were likely or highly likely to have a TBD, with particular relevance attributed to county of residence and living conditions. Also of note, almost a third of those reporting severe symptoms had received a previous Lyme disease diagnosis. These findings underscore the need for further surveillance among vulnerable populations at risk for TBDs.
Cosmic ray effects on microelectronics. Part 3. Propagation of cosmic rays in the atmosphere. Memorandum report

Abstract : Cosmic-ray nuclei that enter the atmosphere will subsequently breakup into lighter nuclei due to collisions with air particles. They also undergo a gradual loss of energy due to ionization. The fluxes and energy spectra of particles were calculated for several atmospheric depths and geomagnetic locations. The results of these radiation transport calculations are plotted as integral Linear Energy Transfer (LET) spectra showing the total number of particles that can contribute to energy lows in silicon above a given threshold value. The results can then be used to calculated the upset rate induced by cosmic ray nuclei for devices of known size and critical charge. Topics examined include: geomagnetic cutoff, soft upsets, and single event upsets.
A High Level of Antimicrobial Resistance in Gram-Positive Cocci Isolates from Different Clinical Samples Among Patients Referred to Arsho Advanced Medical Laboratory, Addis Ababa, Ethiopia

Background Gram-positive cocci are clinically important pathogens that cause infections and their development of antibiotic resistance continues to pose a severe threat to public health. Therefore, this study aims to investigate the level of antimicrobial resistance among Gram-positive cocci isolated from different clinical samples among patients referred to Arsho Advanced Medical Laboratory, Addis Ababa, Ethiopia. Methods From January to April 2018, a cross-sectional study was conducted at Arsho Advanced Medical Laboratory. Seven hundred ninety-two (792) different clinical samples were obtained from 792 individuals and inoculated into blood culture bottles and Blood Agar base. Bacterial identification was done using the number, type, and morphology of colonies, as well as Gram staining, catalase testing, and coagulase test after isolation of pure growth on culture media using the standard operating procedure. VITEK 2 compact system was used for bacterial identification and drug susceptibility testing. The information entry and analysis were performed by using SPSS version 20. Results Out of 792 clinical samples cultured, the prevalence of Gram-positive cocci was 12.6% (n=100/792). The most frequent one is S. aureus 54% (n=54/100) followed by coagulase-negative Staphylococcus species 42% (n=42/100), S. agalactiae 1% (n=1/100) and E. faecalis 3% (n=3/100). Penicillin showed the highest resistance rate 85% (n=85/100), followed by sulfamethoxazole/trimethoprim (47%), and oxacillin (38%); however, highest sensitivity was seen towards linezolid 97% (n=97/100) and vancomycin 94% (n=94/100). The total multi-drug resistance (MDR) Gram-positive cocci were 44% (n=44/100). Conclusion This study demonstrated high antimicrobial resistance and multi-drug resistance. This suggests that the importance of continuous monitoring of antimicrobial resistance patterns is crucial for selecting the suitable drug for treatment and infection prevention.

Hailullah (Sleeping after Fajr Prayer) and Negative Emotional States among University Students

: Sleep plays a vital role in physical and psychological well-being throughout life. Many studies have revealed the effect of sleep however, not many have revealed the effect of sleeping in the morning after Fajr prayer ( Hailullah ) on a person's mental health condition. This study aims to see the relationship between Hailullah and negative emotional states among University students. As much as 483 respondents have filled out the scale, but 18 respondents reported not or rarely do the Fajr prayer and the remaining 235 respondents prayed at the end of time. Thus, the data is processed further for a number of 230 respondents who meet the criteria. The instrument used to measure psychological conditions is DASS 21 which reveals a person's level of depression, anxiety, and stress. The results showed that there is significant relationship between sleep behavior after Fajr prayer ( Hailullah ) with depression, anxiety, and stress. The significant value (2-tailed) between Hailullah and depression is 0.000, between Hailullah and Stress is 0.003 meanwhile, the relationship between Hailullah and anxiety has a sig value. (2-tailed) of 0.000. These results show that the higher the Hailullah behavior the higher the level of depression, anxiety, and stress a person has. Findings in this study are sufficient to support the prohibition of sleep after dawn prayer for Muslims. However, this research was conducted in Indonesia, where the time of night and day is quite balanced.
Historical Background and Significance of Embryo Transfer Technology in Cattle with its Relevant Applications

superovulation, embryo cryopreservation In cattle, embryo transfer technology is widely used to amplify the reproductive rates of genetically improved superior females, planed mating, twinning, disease control, better pregnancy rate in repeat breeder cattle and increment of production of farm and reproductive rates. However, embryo transfer is widely used owing to its potential benefits. Hormonal protocol and synchronization improvements increase the embryo production rates via superovulation. This review details the embryo production technique, transfer of embryo from donor to recipient and the factor that are necessary for transfer of embryo from donor to recipient for production of offspring. Previously limited information existing regarding embryo transfer and its significance in farm animals therefore, in future this review might be helpful in improving the reproductive potential of farm animals.
