Cumulative Performance Index Research Articles

Impact of individual, combined and sequential stress on photosynthesis machinery in rice (Oryza sativa L).

Abiotic stresses such as heat, drought and submergence are major threats to global food security. Despite simultaneous or sequential occurrence of these stresses being recurrent under field conditions, crop response to such stress combinations is poorly understood. Rice is a staple food crop for the majority of human beings. Exploitation of existing genetic diversity in rice for combined and/or sequential stress is a useful approach for developing climate-resilient cultivars. We phenotyped ~400 rice accessions under high temperature, drought, or submergence and their combinations. A cumulative performance index revealed Lomello as the best performer across stress and stress combinations at the seedling stage. Lomello showed a remarkable ability to maintain a higher quantum yield of photosystem (PS) II photochemistry. Moreover, the structural integrity of the photosystems, electron flow through both PSI and PSII and the ability to protect photosystems against photoinhibition were identified as the key traits of Lomello across the stress environments. A higher membrane stability and an increased amount of leaf chlorophyll under stress may be due to an efficient management of reactive oxygen species (ROS) at the cellular level. Further, an efficient electron flow through the photosystems and, thus, a higher photosynthetic rate in Lomello is expected to act as a sink for ROS by reducing the rate of electron transport to the high amount of molecular oxygen present in the chloroplast. However, further studies are needed to identify the molecular mechanism(s) involved in the stability of photosynthetic machinery and stress management in Lomello during stress conditions.

Effects of bis-chelated copper in growth performance and gut health in broiler chickens subject to coccidiosis vaccination or coccidia challenge.

Copper (Cu) is widely used at high levels as growth promoter in poultry, the alternative source of Cu to replace the high level of inorganic Cu at poultry farm remains to be determined. Three floor pen experiments were conducted to evaluate the effects of Cu methionine hydroxy-analogue chelate (Cu-MHAC, MINTREX®Cu, Novus International, Inc.) on growth performance and gut health in broilers in comparison to CuSO4 and/or tribasic copper chloride (TBCC). There were 3 treatments in experiment#1 (0, 30 and 75ppm Cu-MHAC) and experiment#2 (15 and 30ppm Cu-MHAC, and 125 ppm CuSO4), and 4 treatments in experiment #3 (15 and 30ppm Cu-MHAC, 125ppm CuSO4 and 125ppm TBCC) with nine replicates pens of 10-13 birds in each treatment. The levels of other minerals were equal among all treatments within each experiment. All birds were orally gavaged with a coccidiosis vaccine at 1x recommended dose on d0 in experiment#1 and #2 and 10x recommended dose on d15 in experiment #3. Data were analyzed by one-way ANOVA, means were separated by Fisher's protected LSD test. A p ≤ 0.05 was considered statistically different. In experiment #1, 30 and 75ppm Cu-MHAC improved FCR during grower phase, increased jejunal villus height and reduced jejunal crypt depth, 30 ppm Cu-MHAC increased cecal Lactobacillus spp. abundance in 41days broilers. In experiment #2, compared to CuSO4, 15ppm Cu-MHAC increased cumulative performance index in 28days broilers, 15 and/or 30ppm Cu-MHAC improved gut morphometry, and 30ppm Cu-MHAC reduced the abundance of E. coli and Enterobacteriaceae in cecum in 43days broilers. In experiment #3, 15ppm and 30ppm Cu-MHAC improved FCR vs. CuSO4 during starter phase, reduced the percentage of E. coli of total bacteria vs. TBCC, 30ppm Cu-MHAC increased the percentages of Lactobacillus acidophilus, Lactobacillus spp. and Clostridium cluster XIVa of total bacteria vs. both CuSO4 and TBCC in the cecum of 27days broilers. In summary, low doses of Cu-MHAC had comparable growth performance to high dose of TBCC and CuSO4 while improving gut microflora and gut morphometry in broilers subject to coccidiosis vaccination or coccidia challenge, indicating that low doses of bis-chelated Cu could be used as a complimentary strategy to improve animal gut health.

Reliability, Validity, and Responsiveness of the Craniocervical Flexion Test in People Who Are Asymptomatic and Patients With Nonspecific Neck Pain: A Systematic Review and Meta-Analysis.

Among the tests designed to evaluate neck neuromuscular function, the craniocervical flexion test (CCFT) assesses the function of the deep cervical flexor muscles (DCFs). The purpose of this study was to conduct a review and meta-analysis of published articles about all measurement properties of the different CCFT versions (CCFT Activation Score [CCFT-AS], CCFT Performance Index [CCFT-PI], CCFT Cumulative Performance Index [CCFT-CPI], and CCFT alternative procedures for measuring activation level (CCFT1) or endurance (CCFT2) in people who were asymptomatic and people with nonspecific neck pain. PubMed Central, MEDLINE, CINAHL, Scopus, Web of Science, and Google Scholar were searched from inception to June 30, 2020. Studies were selected if they reported data on reliability, validity, and/or responsiveness of the CCFT in adults who were asymptomatic or who had nonspecific neck pain. Two reviewers independently selected the studies, conducted quality assessment, and extracted the results. All meta-analyses used a random-effects model. Twenty-one studies met the inclusion criteria. The rating of interrater reliability (assessed for CCFT-AS and CCFT-CPI) was positive only for using the test at a group level. The same rating was ascribed to the intrarater reliability of CCFT-AS, CCFT1, and CCFT2, whereas CCFT-PI and CCFT-CPI showed positive intrarater reliability for assessment of individuals as well. CCFT validity was rated as positive for expressly assessing DCF action when measuring DCF activation through electromyography-not through ultrasonography-or craniocervical flexion motion as well as for differentiating patients who were asymptomatic and patients who had nonspecific neck pain (only the AS version). CCFT validity was rated as negative for investigating the CCFT performance correlation with the severity of nonspecific neck pain. CCFT responsiveness was rated as negative. The CCFT is a potentially useful tool for detecting impairment in DCF control and identifying patients who have nonspecific neck pain and who would benefit from a targeted intervention. However, the limited reliability affects its suitability for that purpose. Further research on the reliability of different CCFT versions in which the raters are thoroughly trained is strongly recommended. The CCFT might help to detect impairment in DCF control and identify patients who have nonspecific neck pain and who would benefit from a targeted intervention. However, the poor reliability of most versions of the test greatly limits its application in clinical practice. Only CCFT-PI and CCFT-CPI seem reliable enough to help in clinical decision-making at the individual level.

The Productivity of Non-AGP Broiler Small-Holder Businesses Based on Production, Economy and Social Demography

The study investigated the productivity of smallholder broiler farming with and without AGP to identify the difference between the utilization and absence of antibiotic growth promoter (AGP) incorporated into the broiler feed based on production (feed efficiency and cumulative performance index), economy (farming capacity and income), and socio-demography (farmers’ education background, age, farming experience, and farming motivation) in Central Java Province. The study was conducted through a survey of broiler farmers in one partnership company. The data analysis included analysis of variance based on a stratified GLM (general linear model) and correlation analysis. The result did not identify significant differences in the production aspects in either AGP or non-AGP farming, among different regencies, and farm size. In 2018, when farms stop using the AGP, the farm production is better than in 2017 when the AGP was used. Based on the economic aspect, the AGP and non-AGP administration did not affect farming capacity and income. The socio-demographic aspect showed that education significantly affected the success of broiler farming, while farmers’ age, farming experience, and farming motivation did not affect the production of broiler farming. The result of correlation analysis showed that education background contributed to feeding efficiency and cumulative performance index. The conclusions are (1) broilers fed with either AGP or non-AGP containing feed showed relatively similar performance, (2) the government policy on the prohibition of AGP does not contribute to the decrease of farmers’ income and (3) the demographic aspect affecting the success of the broiler farming business is the farmers’ education level.

Performance Evaluation of Al-SiC Nanofluids Based MQL Sustainable Cooling Techniques During Turning of EN-24 Steel

The conventional cutting fluids are used in metal cutting processes for cooling and lubrication. However, the use of cutting fluids is creating the environmental and biological problems. In order to minimize these problems, it is essential to move towards sustainable cooling techniques. The present investigation determine the influence of sustainable cooling techniques such as cryogenic cooling, minimum quantity lubrication, Al2O3/soluble oil nanofluids based minimum quantity lubrication, SiC/soluble oil nanofluids based MQL and Al-SiC/soluble oil hybrid nanofluids based minimum quantity lubrication on output characteristics during turning of EN-24 steel. For experimentation nanofluids were formulated with accumulation of different weight percentages (0.5wt.%, 1.0wt.%, 1.5wt.%) of Al2O3, SiC and Al-SiC nanoparticles to the soluble oil. The thermal and tribological properties of Al2O3/soluble oil nanofluids, SiC/soluble oil nanofluids and Al-SiC/soluble oil hybrid nanofluids were analyzed. Individual machining performance such as surface roughness height, tool wear and specific energy lead to ambiguous understanding. So, the cumulative performance index is also calculated. The cumulative performance index is used to determine the performance of different sustainable cooling techniques during turning of EN-24 steel. The experimental results revealed that the turning performance of EN-24 steel under Al-SiC/soluble oil hybrid nanofluids based minimum quantity lubrication environment is superior then other machining environments.

Performance evaluation of PVD TIALN coated carbide tools vis-à-vis uncoated carbide tool in turning of titanium alloy (Ti-6Al-4V) by simultaneous minimization of cutting energy, dimensional deviation and tool wear

Titanium alloys are difficult-to-machine materials because of their poor machinability characteristics. Machining and machining performance evaluation for such materials is still a challenge. Individual machining performance indices like cutting forces, cutting energy and tool wear lead to ambiguous understanding. In this work, a Cumulative Performance Index (CPI) is defined which amalgamates non-dimensional forms of specific cutting energy, back force and average principal flank wear in turning. The CPI focuses upon simultaneous minimization of specific cutting energy, dimensional deviation and average principal flank wear. The defined index is then used to evaluate performance of five commercially available physical vapor deposited (PVD) TiAlN coated tungsten carbide/cobalt inserts vis-à-vis uncoated tungsten carbide/cobalt insert in turning of Ti-6Al-4V. Cutting forces were monitored during turning and tool wear was measured after turning experiments. The results showed that the performance of coated inserts was either comparable or poor than uncoated insert; and in no case, coated inserts performed better than uncoated insert. Although commercial recommendations are in place to use PVD coated inserts for enhanced machinability of titanium alloys, the use of coated inserts is not justified keeping in view the energy spent in coating and insignificant improvement in performance.

Performance Evaluation of Some Native Rice Cultivars of the Kaippad Farming System of Kerala State of India

Complex and ecologically responsive rice-fish farming systems have evolved in the coastal wetland regions of India over centuries. Kaippad is such an indigenous rice-fish farming system of coastal North Kerala in India. It is a natural system utilizing indigenous knowledge and local resources. The proximity to sea and subsequent periodic sea inundation ensure the uniqueness of this system. However kaippad farms are decreasing in area and the traditional salt tolerant rice cultivars cultivated in the area are also slowly receding from the scene owing to low productivity. Performance evaluation of five popular rice cultivars was attempted based on performance index and cumulative performance index to find out the most promising among the traditional varieties. The study revealed that the cultivar Kuthiru ranked first based on the cumulative performance index calculated on the basis of thirteen characters including six growth characters and seven yield characters. The cultivars Kuttusan and Orkazhama ranked second and third. Selection and further improvement programmes using these cultivars will give rise to promising rice varieties suited for the needs of this special rice ecosystem.

Data driven output joint probability density function control for multivariate non‐linear non‐Gaussian systems

This study presents a novel data-based joint probability density function (JPDF) control strategy for multivariate non-linear non-Gaussian stochastic systems so that the output JPDF of the system can be made to follow a desired JPDF. The output JPDF, which is usually immeasurable, is estimated according to the output sequence of the system. The multi-step-ahead cumulative performance index is constructed with respect to the control objective and is minimised based on an intelligent optimisation algorithm. By minimising this performance function, a new predictive controller design algorithm is established with more simple formulation and less computation load than existed results. Furthermore, a new approach is developed to guarantee ‘convergence in distribution’. Finally, simulations are given to demonstrate the effectiveness of the proposed control algorithm and some desired results have been obtained.

Effect of Targeted Strength, Endurance, and Coordination Exercise on Neck and Shoulder Pain Among Fighter Pilots

To explore in Danish F-16 pilots: (1) the effect on neck and shoulder pain of a 24-week training intervention including targeted training of the deep neck muscles; (2) selected clinical signs and symptoms at baseline; (3) the prevalence and intensity of neck and shoulder pain. Fifty-five F-16 pilots were randomized to 24 weeks of 3-times-a-week training (n = 27) using individual training diaries or to a control group (n = 28) that did not receive any treatment. The primary outcome was reduction in neck and shoulder pain over the previous 3 months and previous 7 days, estimated on an 11-point numeric box scale. Analysis of data was by intention-to-treat. Baseline clinical examination included palpation of muscles and joints and a craniocervical flexion test with an activation score of 10 as best and a cumulative performance index of 300 as best. At baseline, 82% of the participants experienced neck pain within the last year. Tenderness of either the right or the left levator scapulae was significantly indicative of self-reported neck pain within the last 3 months (P = 0.02). In craniocervical flexion test, the mean activation score was 6.7 (6.1 to 7.3) and the mean cumulative performance index was 127.6 (107.0 to 153.0). At follow-up, analyses of covariance revealed a clinically significant decrease from 2.0 to 1.0 in neck pain during the previous 3 months in the training group (P = 0.01) compared with the control group. High prevalences of self-reported neck and shoulder pain and clinical signs and symptoms were found among Gz-exposed F-16 pilots with repeated whiplash-like exposures. Twenty-four weeks of targeted training combining deep neck muscle, strength, and endurance training proved effective in reducing neck pain.
