Power Planning

Research article of Global Journal of Energy and Environment Power Planning Peijun Jiang, Yiqian Gao, Ao Luo School of Electrical and New Energy, China Three Gorges University 43002, China This paper calculates the existing system reliability index and typical daily optimal load distribution, studies the optimization problem of the generator unit’s investment plan in the next ten years, and uses the minimum cost of the investment plan to establish a multi-objective planning model. Combined with the artificial bee colony algorithm. It also discusses the impact of a large number of renewable energy power generation access power systems on traditional power system planning, and proposes an experimental model to solve this problem. Based on the system enumeration method of fault enumeration, enumerate all possible states of the system at each moment, consider the total cost of the system, increase the load demand constraint on the basis, and obtain the probability of occurrence of low-order faults. LOLP, EENS and power outage fees. After the above analysis, after the fault order reaches 5th order, the LOLP of the system is negligible, so the power loss cost is considered to be 4th order. Using the minimum total cost as the objective function, the artificial bee colony algorithm is used to find the optimal solution. The uncertainty of the output of renewable energy in the power system greatly increases the risk of operation scheduling, does not guarantee the quality of power, and is currently economically poor. In view of the difficulties caused by the system components in solving nonlinear constrained power supply planning, an experimental model is also established.

Finally, the robotic claws of the robot arm are used to control the rotation of the robot by multiple bionic control. Keywords: Fan grabbing; Weighing and Forming; RBF neural network algorithm ...

Adolescent Sexting: A Narrative Review

Review Article of International Journal of Psychological Research and Reviews Adolescent Sexting: A Narrative Review Tiffany Field, PhD University of Miami/Miller School of Medicine; Fielding Graduate University This narrative review is based on a literature search on PsycINFO and PubMed that involved entering the terms adolescent sexting for papers published during the last five years. Following exclusion criteria, 52 papers could be classified as sexting studies including research on the prevalence, effects/comorbidities, risk factors and interventions for those problems. Most of the studies have been conducted in the U.S. where the prevalence of sexting has ranged from 5% to 29%. Sexting has typically been consensual, or at least the recipient has been known, although some forwarding of sext messages has occurred. The effects of sexting have included sexual activity, problematic relationships, mental health problems, other addictions and legal problems. The predictor or risk variables have included male gender, extraverted personality, low self-esteem, depression, impulsivity, peer pressure and the lack of parental monitoring. Like other literature on adolescent problems, this research is limited by primarily deriving from self–report and parent report and by the absence of longitudinal data that might inform whether the data being reported are effects of or risk factors for adolescent sexting and the need for prevention/intervention research.

Evaluation of Yield and Physicochemical Properties of Single Cereal Grain Akamu and Pre- and Post- Processed Multigrain Cereal Akamu Powders

Research Article of International Journal of Food and Nutrition Research Evaluation of Yield and Physicochemical Properties of Single Cereal Grain Akamu and Pre- and Post- Processed Multigrain Cereal Akamu Powders Obiegbuna, J.E*., Nwankwo, J.A., Ozue, J.O. and Okolo A.C. Department of Food Science and Technology, Faculty of Agriculture, Nnamdi Azikiwe University, Awka, Anambra State, Nigeria The yield and physicochemical properties of single grain and multigrain akamu powders were evaluated. Akamu, ogi or pap, powders were produced by soaking (fermenting) cereal grains (48-72 h), wet-milling, sieving, dewatering, drying (50oC) and pulverizing maize (MBA), pearl millet (PMBA) and sorghum (SBA). Multigrain akamu was produced by co-fermenting equal proportions of maize, pearl millet and sorghum (Blend1); and singly fermenting these cereals and blending the end products (Blend2). Yield, proximate and mineral compositions, functional and sensory properties of akamu were analyzed following established methods. The yield of MBA, PMBA, SBA, Blend1 and Blend2 were respectively 60%, 70%, 80%, 53.33% and 68.67%. Chemically, SBA had significantly (p<0.05) higher protein (10.17%), fiber (8.00%), iron, zinc, potassium and sodium contents than MBA and PMBA. The carbohydrate content of PMBA (69.27%) was higher (p < 0.05) than that of MBA (66.20%) and SBA (66.30%). PMBA had the lowest protein (7.55%) and MBA the lowest fiber (3.97%) content. The fat (6.27%) and ash (4.67%) of PMBA were significantly higher than that of SBA with 5.47% and 2.00%, respectively. Only the ash, carbohydrate, iron and sodium contents of multigrain akamu differed significantly (p<0.05) with Blend1 having higher carbohydrate and iron values but lower ash and sodium values. The water absorption capacity (WAC) of PMBA (1.87 g/g) was lower (p<0.05) than other single and multi grain samples. MBA had lowest emulsion activity (EA) (44.33%) but highest emulsion stability (ES) of 77.43% while SDA had the highest EA (50.00%). The ES of PMBA ...
