An Improved Genetic Algorithm for the Virtual Machine Placement Problem

The dramatically increasing energy consumption of data centres is an important issue. Server consolidation is now regarded as one of the most effective ways to reduce the energy consumption in data centres. Server consolidation can be formulated as a Virtual Machine (VM) placement problem, and Genetic Algorithm (GAs) have been used to find an optimal solution to the VM placement problem. However, the slow computation time is a main concern of the GAs. This paper aims to improve the efficiency of the GAs. In this paper, we propose a new GA, namely Improved Genetic Algorithm (IGA), which is a GA enhanced by a new Initial Population Generation Strategy (IPGS), a new Knowledge-based Crossover Strategy (KCS), and a new Knowledge-based Mutation Strategy (KMS). Extensive experiments are conducted to illustrate the efficiency of the IGA.
Epidemiology of Inflammatory Bowel Disease in Iran: A review of 803 cases

Aim: To gain recent characteristic information about inflammatory bowel disease (IBD) in Iran. Background : Inflammatory bowel disease (IBD) was believed to be infrequent in Iran; however, during the recent years its prevalence has been continuing in our country. Patients and Method: Between 1992 and 2007, a total of 803 IBD patients (671 ulcerative colitis (UC), 109 Crohn's disease (CD) and 23 indeterminate colitis (IC)) referred to our research centre. We evaluated the demographic data, extraintestinal manifestations, chief complaints and extension of disease in this group of patients. Results: The mean age at diagnosis was 33.01, 33.18, and 34.52 years in UC, CD, and IC patients, respectively. The male to female ratio was 0.78 for UC patients while it was 1.18 in CD patients. Patients with UC chiefly presented by hematochezia (54.24%), whereas those with CD and IC complained of abdominal pain (55.96% and 47.82%, respectively). Totally, 67.51% UC patients, 70.64% CD patients and 73.90% IC patients reported extra intestinal manifestations. The most involved section was left colon in UC (90.49%) and colon in CD patients (75%). Conclusion: The demographic and clinical picture of IBD is more or less the same as other developing countries; however, the rarity of CD in Iran is noted. Although the true epidemiologic profile of IBD in Iran is still unknown, it is not as rare as previously thought and it seems as if gradual adoption of a western lifestyle may be associated with continuing rise in IBD.
Hybrid succession teams: Understanding their formation and conditions for success

ABSTRACT This article focuses on hybrid succession teams that comprise both family and nonfamily members, to identify the reasons and criteria for forming these teams, as well as the difficulties they encounter during the succession process. The empirical results, based on three longitudinal case studies (two failures and one success), reveal the strong and sometimes negative influence of the predecessor on the constitution and functioning of these succession teams. In particular, the predecessor may choose this form of succession and the members of the team, based solely on the complementarity of their skills. The predecessor’s natural preference for family members also can be a source of conflict, because it creates information asymmetry between family and nonfamily successors. Consequently, a lack of strong ties among team members and the presence of information asymmetry can increase the risk of succession team dissolution.
Final results of the Sunbelt Melanoma Trial

9003 Background: The Sunbelt Melanoma Trial is a multicenter prospective randomized prospective trial to evaluate the role of high-dose interferon alfa-2b (IFN) or completion lymph node dissection (CLND) in patients with melanoma staged by sentinel lymph node (SLN) biopsy. Methods: Eligible patients aged 18 to 70 years with primary melanoma ≥1.0 mm Breslow thickness underwent SLN biopsy. In Protocol A, patients with a single tumor-positive lymph node after SLN biopsy and CLND were randomized to observation vs. high dose IFN (20 MU/m2/d i.v. x 4 wks followed by 10 MU/m2 s.q. TIW x 48 wks). In Protocol B, patients with tumor-negative SLN by standard histopathology and immunohistochemistry underwent molecular staging of the SLN by reverse transcriptase polymerase chain reaction (RT-PCR) to detect melanoma- specific mRNA (tyrosinase, MART 1, MAGE 3, gp100); patients with RT-PCR-positive SLN were randomized to observation vs. CLND vs. CLND + IFN (20 MU/m2/d i.v. x 4 wks only). Randomization was stratified for .
The effect of nomophobic behavior of nurses working at surgical clinics on time management and psychological well-being

ABSTRACT Objective: This study examined the effects of nomophobic behaviors of surgical nurses on time management and psychological well-being. Background: Addicted use of smartphones in the working environment is a social disease defined as nomophobia. Methods: This is a descriptive and cross-sectional study. This study was conducted between December 2018 and March 2019 at a university hospital located in Turkey. 314 nurses who met the inclusion criteria formed the sample of the study. Results: A statistically significant relationship was found between the sub-dimensions of the Nomophobia Scale and psychological well-being (p < .05). The stepwise regression analysis, which was conducted to examine the effects of independent variables on the sub-dimensions of the scales, showed statistically significant correlations. Conclusions: Nomophobia prevents patients from communicating effectively with health professionals, leads to misunderstandings and reduces the amount of work per unit time and the quality of work.
Technoscience – Science Without Scientists?

The article outlines a look at technoscience or mode 2 as a results of the development of statistics as a mathematical method and an instrument of social management, as well as the deprofessionalization of science due to the overproduction of specialists and the introduction of design forms of work into the practice of the scientific community. A decrease of the scientists’ expert status is noted, and an assessment is given of the prospects for the complete degeneration of classical science into the technoscience.
Analysis of Influence of Family Status on Dietary Behavior of Preschool Children through Data Samples: A Case Study of Eating Frequency of Western Fast Food

Children’s eating habits are closely related to not only their own growth and development, but also their psychological development. In order to explore the influence of family status on the frequency of Western fast food eating for preschool children, this study selected five aspects of preschool education, including the cognitive level of adopters and family income, as the research dimension, and used SPSS software to analyze nearly 2000 groups of data. The study found that the low cognitive level of adopters in Western fast food behavior caused children to eat Western fast food more frequently. Children with high family income, decent parents, high educational level of parents and family living conditions had higher frequency of eating Western fast food. Finally, it is proposed to improve children’s dietary behavior by improving their dietary education, education ability and their own dietary behavior, developing diversified and interesting dietary health, health education activities, and strengthening the publicity of dietary education in kindergartens.
Overview Impact Of Application Of Queuing Theory Model On Productivity Performance In A Banking Sector

Banking sectors have perpetual queues owing to the significance of the services they render to humanity and this poses a merging challenge of queue management in the execution their jobs and in the effective delivery of services to their customers. The study focuses on the role of queuing theory in the banking sectors thus far from pedigree of queuing theory till date. This study used the historical approach to juxtapose the likelihood of the impact of queuing in the various activities in the banking as seen in the regular applications to established areas of telecommunications systems and engineering. The outcome of this review espouses that a few approaches have been applied to sort the problems encountered in the banking sectors for needful improvement. Some of these approaches are ANN (Artificial Neural Network), BPR (Business Process Reengineering) M/M/1, M/G/1 and the Erlang B&C formulas for the management of excessive bank reserves and customer queues in terms of waiting times and economic cost. These approaches have been able to improve the performance of the banking sector to an extent, however there is still a couple of limitation regarded as external factors that varies from one banking system to another and lots of works are needed to further combat the problems faced by the banking sectors.
Microbial Etiology of Acute Gastroenteritis in Pediatric Patients in Western India.

Introduction: Acute gastroenteritis is a major cause of illness and death among infants and young children worldwide. According to the World Health Organization (WHO), an estimated 2.5 billion cases of diarrhea occur among children under 5 years of age each year. Nearly one in five pediatric deaths (about 1.5 billion each year) is due to diarrhea. Present study was thus drawn to identify microbial etiology of acute gastroenteritis in pediatric patients in Western India. Materials and Method: This was Prospective laboratory based study approved by Institutional Ethical committee. 100 stool samples were collected from children admitted with acute diarrhea of 72 hours or less duration in 1- 60 months of age over a period of one year. Bacteria were identified by standard Microbiological methods and serotyping of isolated Escherichia coli (E. coli) was done. Rotavirus antigen was detected by Enzyme Linked Immunosorbant Assay (ELISA) followed by genotyping by Reverse Transcriptase Polymerase chain Reaction (RT-PCR) and Multiplex PCR. Parasitic identification was done by microscopy. Results: 74% of children with diarrhea were in the age group of 7 to 12 months. Watery diarrhea (94%) was the commonest clinical presentation, followed by vomiting (78%), fever (78%), and dehydration (74%). Pathogenic bacteria were isolated in 51% of samples. Escherichia coli was most common (48%) followed by Shigella flexneri (2%) and Vibrio cholerae (1%). The most prevalent E. coli type was Enterotoxigenic Escherichia coli (ETEC) (20.8%) followed by Enteropathogenic Escherichia coli (EPEC)(16.7%), Enterohaemorrhagic Escherichia coli (EHEC) (4.1%), and STEC (2.1%). The most prevalent serotypes of ETEC were O27, O23, and O169. Among EPEC most prevalent serotypes were O90, O26. The most prevalent EHEC strain found in this study was O71. Rotavirus was detected in 35% of patients. Most prevalent Rotavirus genotype was G9P[4] (28.6%) followed by G2P[4] (21.4%), G1P[8] (21.4%), G12P[6] (14.3%), G9P[8] (7.1%). Parasitic etiology was detected in 5% of cases. Coinfection of E.coli and Rotavirus was detected in 23% of children. Rotavirus was most commonly associated with EPEC (25.7%) followed by ETEC (17.1%). Conclusion: In the present study, E. coli was the commonest microorganism followed by Rotavirus. Thus, the importance of safe water and food hygiene would be most important intervention to prevent acute gastroenteritis in children along with Rotavirus vaccine. Keywords: Rotavirus, E. coli, WHO, NIV, ETEC, EPEC, EHEC, STEC

Results: 11 articles were selected after applying the inclusion/exclusion criteria. The studies showed that the main triggering catheters of infection are the provisional catheters, of which stand out the double lumen. Conclusion: Due to the high use in health services, vigilance in the use of temporary catheters, especially double lumen, is recommended.
Smoking, DNA methylation and lung function: a Mendelian randomization analysis to investigate causal relationships

Whether smoking-associated DNA methylation has a causal effect on lung function has not been thoroughly evaluated. We investigated the causal effects of 474 smoking-associated CpGs on forced expiratory volume in one second (FEV1) in two-sample Mendelian randomization (MR) using methylation quantitative trait loci and genome-wide association data for FEV1. We found evidence of a possible causal effect for DNA methylation on FEV1 at 18 CpGs (p<1.2×10−4). Replication analysis supported a causal effect at three CpGs (cg21201401 (ZGPAT), cg19758448 (PGAP3) and cg12616487 (AHNAK) (p<0.0028). DNA methylation did not clearly mediate the effect of smoking on FEV1, although DNA methylation at some sites may influence lung function via effects on smoking. Using multiple-trait colocalization, we found evidence of shared causal variants between lung function, gene expression and DNA methylation. Findings highlight potential therapeutic targets for improving lung function and possibly smoking cessation, although large, tissue-specific datasets are required to confirm these results.
Fístula cutánea secundaria a úlcera de abomaso de una cabra

Las úlceras abomasales son raras y poco conocidas en los pequeños rumiantes y en los rumiantes, en general. Estas llegan a presentarse por diferentes causas como lo son: la dieta, el estrés, la alteración de los mecanismos protectores de la mucosa gástrica, entre otros. En este artículo, se presenta el caso de un caprino hembra raza criolla de aproximadamente diecisiete años, que presentaba una lesión en la región ventral del abdomen, entre la cicatriz del ombligo y el cartílago xifoides, y, adicionalmente, tenía una enfermedad articular. Como método de diagnóstico se realizaron exámenes paraclínicos como: cuadro hemático, coprológico y toma de rayos x, en donde se determinó el diagnóstico final que fue una úlcera abomasal grado 3 y una enfermedad articular degenerativa. El tratamiento se realizó con penicilina sódica (22 000 UI/kg durante cinco días cada doce horas), gentamicina (6 mg/kg durante tres días cada 24 horas), cuatro aplicaciones de complejo B (2 ml cada 48 horas), omeprazol (10 mg/kg cada doce horas por quince días) y lavados diarios de la herida con solución salina durante quince días. El animal fue dado de alta a los veinte días con cierre total de la herida

Objective:To compare clinical effectiveness of Nickel Titanium (Ni-Ti) closed coil spring and active tiebacks during space closure in mandibular arch. To compare rate of anterior retraction by using Ni-Ti closed coil spring and active tiebacks in mandibular arch. To compare amount of anchor loss in mandibular arch with Ni-Ti closed coil spring and active tiebacks. Materials and Methods: A total of 20 patients with Class 1 bimaxillary proclination undergoing fixed orthodontic treatment (MBT 0.022 slot) after ? rst premolar extraction will be randomly selected from depatment of Orthodontics & Dentofacial Orthopaedics of K.D. Dental college, and will be divided into two groups for space closure. Patient will be informed about treatment and thesis procedure and consent regarding was taken. The space closure mechanics was allocated to the left or right side of same arch wire in each patient. Group 1 consisted of 10 patients in which right quadrant of maxillary arch, the space closure was done by Ni-Ti closed coil springs in 10 patients and by active ligature on left quadrant of the same 10 patients. Group 2 consisted of same 10 patients in which left quadrant of same arch, the space closure will be done by active ligature in 10 patients and by Ni-Ti closed coil springs on right quadrant of same 10 patients. The amount of anterior retraction, anchorage loss and rate of space closure was measured before start of retraction and patients will be called at six week interval for evaluation of retraction rate as T0, T1, T2, T3,T4. Results will be assessed on cast and Lateral Cephalogram were repeated at T4 for evaluation of anchorage loss. Result: Rate of anterior retraction and amount of anchorage loss was found to be slightly more with niti closed coil spring as compared to that of active tie back. Conclusion: NiTi closed coil springs achieved faster space closure as compared to the active tieback and significant amount of anchorage loss was also noted with NiTi closed
PREVALENCE OF AND RISK FACTORS FOR UPPER EXTREMITY MUSCULOSKELETAL SYMPTOMS AND DISORDERS AMONG COMPUTER USERS: A CROSS-SECTIONAL STUDY WITH SPECIAL EMPHASIS ON CARPAL TUNNEL SYNDROME

Background: A recent change in the Belgian law lead to the obligation of evaluating the musculoskeletal system among employees using visual display terminal (VDT) during the routine annual visit. We conducted a cross-sectional study to determine prevalence of and risk factors for musculoskeletal symptoms (MSS) and disorders (MSD) in general, and carpal tunnel syndrome (CTS) in particular. Methods: During the routine annual visit all VDT employees of different kinds of companies and occupations were asked about upper extremity MSS by their occupational physician. Participants who met the criteria for MSS within the last month were physically examined in search of a MSD in general, and CTS in particular. Prevalences were calculated, and key risk factors for MSS and CTS were determined using logistic regression analyses. Results: The total prevalence of any upper extremity MSS among 1087 VDT-employees was 31.3%. Neck symptoms (21.6%) were the most frequently reported, followed by shoulder (21.6%), elbow/forearms (4.1%), hands/wrists (7.3%), and finger (5.2%) symptoms. The prevalence of CTS depended on the diagnostic criteria used: 1.8% for symptom-specific CTS (typical anatomical distribution of numbness and paresthesias), 1.2% for examination-confirmed CTS (at least one positive provocative test, Tinel’s nerve percussion test or Phalen’s wrist flexion test), and 0.2% for electrophysiologically-confirmed CTS (abnormal nerve conduction tests). Logistic regression analyses identified increasing age, female gender, the duration of professional VDT use per day, a history of thyroid diseases, and a history of rheumatoid arthritis as significant and independent factors associated with MSS. Adaptation of the work-place was associated with a lower likelihood of MSS. Only increasing age and female gender were identified as significant and independent factors associated with CTS (symptom-specific and examination-confirmed CTS). Job-related factors were not significantly associated with an increased risk for CTS. Conclusions: Our study confirms the high prevalence of MSS among Belgian visual display terminal users (more than 30%). Two work-related factors were clearly associated with MSS: the duration of professional VDT use per day (increased risk) and prior adaptation of the workplace according to advice given by the occupational physician (decreased risk). By contrast, the prevalence of CTS was low (less than 2%), and no job-related risk factors for CTS could be identified among VDT users.
Incorporating Beliefs and Experiences into Choice Experiment Analysis: Implications for Policy Recommendations

We use a choice experiment survey of greater New England residents to understand preferences and WTP to create a new National Park/Recreation Area in Maine. We use the study to analyze how respondents’ beliefs about prior recreational experiences and future outcomes affect policy recommendations from choice experiments. We find that respondents who engage in hunting and snowmobiling are willing to pay significantly more for a park allowing these activities whereas . We also find that willingness to pay for a new National Park in Maine differs based on respondents’ stated beliefs about the status-quo long-term land use. Land managers may find a two-park solution (one allowing the activities and one prohibiting them) would be best; this insight would be missed when neglecting to model conflicting recreational preferences.
Valores óptimos de hemoglobina en el perioperatorio ¿más es mejor?

La anemia y los requerimientos de transfusión sanguínea durante el perioperatorio incrementan el riesgo de eventos adversos. Siendo una limitación la disponibilidad y costos. La adecuada evaluación preoperatoria, la optimización de hemoglobina y riesgo de sangrado tiene un impacto positivo en la disminución de complicaciones. Durante el sangrado transoperatorio deberán emplearse estrategias que ayuden a minimizar el sangrado y disminuir el requerimiento de transfusión por el riesgo asociado a transfusiones. Es imperativo individualizar cada paciente según el contexto y decidir la cifra de hemoglobina optima durante todo el perioperatorio.
The hyperparasitoid Marietta picta mediates the coexistence of primary parasitoids of goji berry psyllid

: Hyperparasitoids could disrupt the biological control system established by primary parasitoids. In Ningxia, China, accidentally introduced Marietta picta Andre was found since 2016 to hyperparasitize the primary parasitoid Tamarixia lyciumi Yang, a native biocontrol agent against the goji berry psyllid Paratrioza sinica Yang et Li. Self-introduced Psyllaephagus arenarius Trjapitzin is also a primary parasitoid of P. sinica when it was first recorded in 2016 from China. To assess the effect of M. picta on the local biological control system, its type and biological characteristics were studied under laboratory conditions, and the levels of hyperparasitism were estimated from 2015 to 2017 in the field. The laboratory results showed that M. picta was an obligate solitary hyperparasitoid. It preferred to attack the mature larvae of T. lyciumi but was not able to attack P. arenarius . Field surveys suggested that introduction of M. picta reduced the second wave of parasitism by T. lyciumi . Free from the hyperparasitism, the well-timed presence of P. arenarius adequately compensated for this hyperparasitoid-driven loss, significantly decreasing the population of P. sinica . Because of the mediation by M. picta , the newcomer P. arenarius could successfully establish a population and co-exist with T. lyciumi to synergistically suppress the populations of P. sinica.
