Skull Evolution Method and Analysis in The Rhinocerotidae: Phylogeny of Early Rhinocerotoids

After phylogeny is measurably disposed of, cranial elements utilized essentially for rumination ought to change most with hypsodonty (high-delegated cheek teeth). These structures should be least phylogenetically restricted. Corollary: structures with significant common ancestry will integrate more morphologically. All living rhinoceroses and many extinct European Plio-Pleistocene species We examined skull, mandible, and upper tooth row form in the dorsal, lateral, and occlusal perspectives using two-dimensional geometric morphometrics. Hypsodonty index was employed to represent eating behaviours. We divided form variation into function, phylogeny, and size using phylogenetically independent comparisons and variation partitioning. We used Escoufier's RV coefficient to evaluate morphological reconciliation. The mandible and upper tooth column covariate most with hypsodonty and least with phylogeny. Skull morphology corresponds least with hypsodonty and most with phylogeny. Low morphological joining between the top tooth line and different parts recommends it is the least phylogenetically restricted. As predicted, the chewing area is confined by function rather than phylogeny, unlike others

Analysis Evaluation of Resource Value Effects Territorial Defense by Broad-Tailed and Rufous Humming Birds

Hummingbirds of the species Selasphorous platycercus and Selasphorous rufus were studied in Colorado, where they displayed territorial behaviour at feeders containing 10%, 20%, and 30% sucrose solutions. At each of the three energy availability levels, the number of invaders, the number of territory owners, and the level of Defence were recorded. After being forced out of their breeding area by Rufous Hummingbirds, Broad-tailed Hummingbirds only bother to defend locations of inferior quality. Both Wide-tailed and Rufous hummingbirds, while keeping tabs on important locations, resort to more flamboyant modes of behaviour, such as extended pursuits augmented with chip cries and aimless wing flapping. According to certain probes, a chase is ready to start if chip calls and hovering are any indication. However, I learned that when an intruder was present, it was only natural to want to get rid of them. Hovering and chip calls were utilised to increase the intensity of the chase. Broad-tailed Hummingbirds were less likely than Rufous Hummingbirds to make chip sounds or hover without giving pursuit

Strategic maintenance technique selection using combined quality function deployment, the analytic hierarchy process and the benefit of doubt approach

The business performance of manufacturing organizations depends on the reliability and productivity of equipment, machineries and entire manufacturing system. Therefore, the main role of maintenance and production managers is to keep manufacturing system always up by adopting most appropriate maintenance methods. There are alternative maintenance techniques for each machine, the selection of which depend on multiple factors. The contemporary approaches to maintenance technique selection emphasize on operational needs and economic factors only. As the reliability of production systems is the strategic intent of manufacturing organizations, maintenance technique selection must consider strategic factors of the concerned organization along with operational and economic criteria. The main aim of this research is to develop a method for selecting the most appropriate maintenance technique for manufacturing industry with the consideration of strategic, planning and operational criteria through involvement of relevant stakeholders. The proposed method combines quality function deployment (QFD), the analytic hierarchy process (AHP) and the benefit of doubt (BoD) approach. QFD links strategic intents of the organizations with the planning and operational needs, the AHP helps in prioritizing the criteria for selection and ranking the alternative maintenance techniques, and the BoD approach facilitates analysing robustness of the method through sensitivity analysis through setting the realistic limits for decision making. The proposed method has been applied to maintenance technique selection problems of three productive systems of a gear manufacturing organization in India to demonstrate its effectiveness

Effect of nutrition-sensitive agriculture interventions with participatory videos and women's group meetings on maternal and child nutritional outcomes in rural Odisha, India (UPAVAN trial): a four-arm, observer-blind, cluster-randomised controlled trial.

BACKGROUND: Almost a quarter of the world's undernourished people live in India. We tested the effects of three nutrition-sensitive agriculture (NSA) interventions on maternal and child nutrition in India. METHODS: We did a parallel, four-arm, observer-blind, cluster-randomised trial in Keonjhar district, Odisha, India. A cluster was one or more villages with a combined minimum population of 800 residents. The clusters were allocated 1:1:1:1 to a control group or an intervention group of fortnightly women's groups meetings and household visits over 32 months using: NSA videos (AGRI group); NSA and nutrition-specific videos (AGRI-NUT group); or NSA videos and a nutrition-specific participatory learning and action (PLA) cycle meetings and videos (AGRI-NUT+PLA group). Primary outcomes were the proportion of children aged 6-23 months consuming at least four of seven food groups the previous day and mean maternal body-mass index (BMI). Secondary outcomes were proportion of mothers consuming at least five of ten food groups and child wasting (proportion of children with weight-for-height Z score SD <-2). Outcomes were assessed in children and mothers through cross-sectional surveys at baseline and at endline, 36 months later. Analyses were by intention to treat. Participants and intervention facilitators were not blinded to allocation; the research team were. This trial is registered at ISRCTN, ISRCTN65922679. FINDINGS: 148 of 162 clusters assessed for eligibility were enrolled and randomly allocated to trial groups (37 clusters per group). Baseline surveys took place from Nov 24, 2016, to Jan 24, 2017; clusters were randomised from December, 2016, to January, 2017; and interventions were implemented from March 20, 2017, to Oct 31, 2019, and endline surveys done from Nov 19, 2019, to Jan 12, 2020, in an average of 32 households per cluster. All clusters were included in the analyses. There was an increase in the proportion of children consuming at least four of seven food groups in the AGRI-NUT (adjusted relative risk [RR] 1·19, 95% CI 1·03 to 1·37, p=0·02) and AGRI-NUT+PLA (1·27, 1·11 to 1·46, p=0·001) groups, but not AGRI (1·06, 0·91 to 1·23, p=0·44), compared with the control group. We found no effects on mean maternal BMI (adjusted mean differences vs control, AGRI -0·05, -0·34 to 0·24; AGRI-NUT 0·04, -0·26 to 0·33; AGRI-NUT+PLA -0·03, -0·3 to 0·23). An increase in the proportion of mothers consuming at least five of ten food groups was seen in the AGRI (adjusted RR 1·21, 1·01 to 1·45) and AGRI-NUT+PLA (1·30, 1·10 to 1·53) groups compared with the control group, but not in AGRI-NUT (1·16, 0·98 to 1·38). We found no effects on child wasting (adjusted RR vs control, AGRI 0·95, 0·73 to 1·24; AGRI-NUT 0·96, 0·72 to 1·29; AGRI-NUT+PLA 0·96, 0·73 to 1·26). INTERPRETATION: Women's groups using combinations of NSA videos, nutrition-specific videos, and PLA cycle meetings improved maternal and child diet quality in rural Odisha, India. These components have been implemented separately in several low-income settings; effects could be increased by scaling up together.

Estimation of the air-tissue boundaries of the vocal tract in the mid-sagittal plane from electromagnetic articulograph data

Electromagnetic articulograph (EMA) provides movement data of sensors attached to a few flesh points on different speech articulators including lips, jaw, and tongue while a subject speaks. In this work, we quantify the amount of information these flesh points provide about the vocal tract (VT) shape in the mid-sagittal plane. VT shape is described by the air-tissue boundaries, which are obtained manually from the recordings by real-time magnetic resonance imaging (rtMRI) of a set of utterances spoken by a subject, from whom the EMA recordings of the same set of utterances are also available. We propose a two-stage approach for reconstructing the VT shape from the EMA data. The first stage involves a co-registration of the EMA data with the VT shape from the rtMRI frames. The second stage involves the estimation of the air-tissue boundaries from the co-registered EMA points. Co-registration is done by a spatio-temporal alignment of the VT shapes from the rtMRI frames and EMA sensor data, while radial basis function (RBF) network is used for estimating the air tissue boundaries (ATBs). Experiments with the EMA and rtMRI recordings of five sentences spoken by one male and one female speakers show that the VT shape in the mid-sagittal plane can be recovered from the EMA flesh points with an average reconstruction error of 2.55 mm and 2.75 mm respectively

&lt;p&gt;BLOCKCHAIN FUNDAMENTAL: PRINCIPAL AND APPLICATION&lt;/p&gt

Leech Infestation Presenting as Severe Rectal Bleeding

Leech or Hirudinea is a major parasite in rural India. Normally, the leech attacks the skin and exposed areas. An 18‑year‑old child presented with bleeding per rectum for 1 day along with giddiness. A history revealed that while the boy was working in a field, had acrawling sensation in the perianal area. After admission, the patient was resuscitated with crystalloids and a limited colonoscopy revealed a rectal ulcer with a leech head attached to its base. The hooklets were removed using foreign body removal forceps and injection Adrenaline at 1:10,000 dilutions was injected in 1 ml aliquots into four quadrant to achieve hemostasis. There was no postprocedure complication. Leech infestation can present with exsanguinating acute severe lower gastrointestinal bleed

Evaluation of Tumor Necrosis Factor-Alpha Gene (&minus;308 G/A, &minus;238 G/A and &minus;857 C/T) Polymorphisms and the Risk of Gastric Cancer in Eastern Indian Population

Introduction: Gastric cancer (GC) is one of the leading causes of cancer-related decimations worldwide. The gastric infection at both the stomach and duodenum with Helicobacter pylori causes inflammation by the tumor necrosis factor-alpha (TNF-&alpha;). The aim of the study was to associate and evaluate the three TNF-&alpha; gene polymorphisms at positions &minus;308 G/A, &minus;238 G/A, and &minus;857 C/T with the risk of GC. Methods: A total of 156 individuals (consecutively diagnosed 95 GC patients and 61 controls) above the age of 18 years were enrolled in the study. Healthy individuals with normal upper gastrointestinal endoscopy (UGIE) irrespective of their family history of GC or peptic ulcer were included as controls. The cited three TNF-&alpha; gene polymorphisms were evaluated using polymerase chain reaction-restriction fragment length polymorphism (RFLP). Results: There was no significant difference in the distribution of gene polymorphisms as genetic factors, TNF-&alpha;&minus;308 GA/AA (22.1% vs. 14.8%, p = 0.2), TNF-&alpha;&minus;238 GA/AA (21% vs. 19.6%, p = 0.8), and TNF-&alpha;&minus;857 CT/TT (8.4% vs. 11.5%, p = 0.5), between GC cases and healthy controls. A subgroup analysis of H. pylori-positive patients showed that there was no significant difference in the distribution of GA/AA polymorphisms in TNF-&alpha;&minus;308 (15(45.5%) vs. 3(23%); p = 0.17) and &minus;238 (12(36.3%) vs. 2(15.4%); p = 0.17), and the distribution of TT/CT &minus;857 CT/TT (13(39.4%) vs. 2(15.4%); p = 0.13), among the GC cases and controls. Conclusion: The statistical comparisons of GA/AA vs. GG genotypes at &minus;308 (with OR = 1.6, 95% CI: 0.6&ndash;3.8), &minus;238 (OR = 1.09, 95% CI: 0.4&ndash;2.4) and TT/CT vs. CC genotypes at &minus;857 (OR = 0.7, 95% CI: 0.2&ndash;2.1) did not suggest any association of TNF-&alpha; with GC in the population herein. Hence, the TNF-&alpha; (&minus;308 G/A, &minus;238 G/A and &minus;857 C/T) may not be the associating factor for GC incidence determined by the PCR&ndash;RFLP method
