Effects of dietary energy and protein dilution and time of feed replacement from starter to grower on broiler chickens performance

An experiment was conducted to study the effects of dietary energy and protein dilution and time of feed replacement from starter to grower on performance of broilers with a 2×3 factorial arrangement in a completely randomized design with 480 day-old broilers from 1-42 day of age. Experimental treatments were 5% energy and protein diluted diets and starter diet was fed to 7, 14 or 21 days and finisher diet was fed beginning at 35 days. Grower diet was fed for variable times depending upon termination of feeding starter diet and initiation of finisher diet. Dilution of both energy and protein had no (P>0.05) significant effect on chicks performance, but significantly (P<0.05) increased breast meat yield. Reduction the time of feeding starter diet did not show any significant effects on bird\u27s performance. From 1-42 days of age, the interaction between dilution of both energy and protein and changing time from starter to grower diets on body weight and feed intake was not significant(P<0.05). The results from this study suggest that diluting of both energy and protein up to 5% from 1-42 days of age and decreasing the time of starter diet had no adverse effect on broiler chickens performance and it may be beneficial economically

Designing a Reverse Logistics Network for End-of-Life Vehicles Recovery

The environmental factors are receiving increasing attention in different life cycle stages of products. When a product reaches its End-Of-Life (EOL) stage, the management of its recovery process is affected by the environmental and also economical factors. Selecting efficient methods for the collection and recovery of EOL products has become an important issue. The European Union Directive 2000/53/EC extends the responsibility of the vehicle manufacturers to the postconsumer stage of the vehicle. In order to fulfill the requirements of this Directive and also efficient management of the whole recovery process, the conceptual framework of a reverse logistics network is presented. The distribution of new vehicles in an area and also collecting the End-of-Life Vehicles (ELVs) and their recovery are considered jointly. It is assumed that the new vehicles distributors are also responsible for collecting the ELVs. Then a mathematical model is developed which minimizes the costs of setting up the network and also the relevant transportation costs. Because of the complexity of the model, a solution methodology based on the genetic algorithm is designed which enables achieving good quality solutions in a reasonable algorithm run time

Nonablative Fractional Laser Resurfacing

The desire to achieve cosmetic rejuvenation and reduce effects of aging and photodamage urged scientists to develop effectual techniques which have minimal side effects and impressive long-term efficacy. Traditional ablative resurfacing laser therapy has been used for several years;however, it has harmful side effects on the patient’s skin such as dyspigmentation, persistent erythema, infections, acneiform eruptions and scarring. It also prolongs downtime, so it puts a significant burden on society. Nonablative resurfacing laser therapy declines side effects of traditional therapies, although it has lower effectiveness in comparison with ablative one.Nonablative fractional resurfacing laser therapy commenced a modern technique which diminished side effects, while maintains the efficacy of traditional methods. The aim of of this current review is to sum up nonablative fractional laser therapies used for skin photorejuvenation at the past and present time and to evaluate the indications,advantages and classification of it and non-fractional resurfacing laser therap

The effect of foliar nutrition of potassium sulfate on morpho-physiological indices of grapevine under salinity stress

Potassium has a main effect on plants salinity tolerance through its effect on cells osmoregulation, and the maintenance of cell turgor. The objective of the present study was to investigate the effect of foliar nutrition of potassium sulfate (PS; 0 and 1.5%) on some morphometric and physiological traits of Bidaneh-Sefid grapevine under salinity condition of NaCl (0, 25, 50 and 100 Mm). This experiment was carried out factorially based on completely randomized design in a greenhouse condition. The result showed that salinity decreased plant height, leaves number, leaves area and re-growth, but foliar application of potassium mitigated the negative impacts of salinity on these morphometric indices. Also, application of 1.5% potassium resulted in the stability of photosynthetic pigments compared to non-treated plants under salinity stress. With increasing salinity, the amount of ion leakage increased until salinity of 100 mM without PS treatment and reached to its highest level (64.2%). While 1.5% PS treatment decreased leaf ion leakage significantly (P≤ 0.01) in treated vines in compared to other untreated plants. Unlike insoluble sugar, the content of soluble sugar and proline as two osmoregulant has shown an increasing trend in the response to salinity and the application of potassium and reached to highest in 100 Mm NaCl and 1.5% PS treatments. Also, the PS foliar application use of sulfate-potassium leaf with increasing potassium concentration and then cell Na+ /K+ adjusting, increased the leaf N, K, Mg and Ca concentration in compared to non- PS sprayed plants

Facility Location and Inventory Balancing in a Multi-period Multi-echelon Multi-objective Supply Chain: An MOEA Approach

A comprehensive and integrated study of any supply chain (SC) environment is a vital requirement that can create various advantages for the SC owners. This consideration causes productive managing of the SC through its whole wide components from upstream suppliers to downstream retailers and customers.  On this issue, despite many valuable studies reported in the current literature, considerable gaps still prevail. These gaps include integration and insertion of basic concepts, such as queuing theory, facility location, inventory management, or even fuzzy theory, as well as other new concepts such as strategic planning, data mining, business intelligence, and information technology. This study seeks to address some of these gaps. To do so, it proposes an integrated four-echelon multi-period multi-objective SC model. To make the model closer to the real world problems, it is also composed of inventory and facility location planning, simultaneously. The proposed model has a mixed integer linear programming (MILP) structure. The objectives of the model are reducing cost and minimizing the non-fill rate of customer zones demand. The cost reduction part includes cost values of raw material shipping from suppliers to plants, plant location, inventory holding costs in plants, distribution cost from plants to warehouses or distribution centers (DCs), and shipping costs from DCs to customer zones. Finally, since the literature of SC lacks efficient Pareto-based multi-objective evolutionary algorithms (MOEAs), a new multi-objective version of the biogeography-based optimization algorithm (MOBBO) is introduced to the literature of the SC. The efficiency of the algorithm is proved through its comparison with an existing algorithm called multi-objective harmony search (MOHS)

Continuous Gas Lift Optimization Using Genetic Algorithm

Abstract: Gas lift is one of a number of processes used to artificially lift oil or water from wells where there is insufficient reservoir pressures to produce the well. The process involves injecting gas through the tubing-casing annulus. Injected gas aerates the fluid to reduce its density; the formation pressure is then able to lift the oil column and forces the fluid out of the wellbore. Gas may be injected continuously or intermittently, depending on the producing characteristics of the well and the arrangement of the gas-lift equipment. Being somehow an ancient tool with an age of over a century, gas lift is though still a challenging problem when overall optimization is the concern. When the injection gas is of a limited supply the problem is finding the best gas allocation scheme. However there are increasingly emerging cases in certain geographic localities where the gas supplies are usually unlimited. The optimization problem then totally travels to the wellbore and completion string and fully engages with multiphase flow concepts. In the present study an intelligent genetic algorithm has been developed to simultaneously optimize all effective factors namely, gas injection rate, injection depth and tubing diameter towards the maximum oil production rate with the water cut and injection pressure as the restrictions. The computations and real field data are mutually compared

Histopathologic Findings of Olfactory Mucosa in COVID-19 Patients

Background: Olfactory manifestations are common findings during the course of COVID-19, while exact physiopathology is not known Aim: We review histological changes of the nasal olfactory mucosa in COVID-19 non-survivors who died in the ICU. Methods: Sampling was done within 1 hour of death under direct vision. Specimens were taken medial to the middle turbinate in the cribriform area and embedded in paraffin blocks and stained by haematoxylin and eosin. Results: The most frequent histologic finding was the infiltration of inflammatory cells mostly comprised of lymphocytes. Inflammatory infiltration of mucosa was seen in all 11 patients with ulceration in 9 cases and neuritis in 3 cases.&nbsp; Conclusion: Inflammatory infiltration of olfactory mucosa may be associated with smell manifestations. Further histological studies will clarify the role of the nasal mucosa in the physiopathology of COVID-19 especially olfactory involvement

Detection and identification of carriers of white spot virus in wild shrimps and crabs in Persian Gulf and Oman Sea (Hormozgan province)

More than 20 viruses have been reported as pathogenic to shrimp.WSV has been found to be highly pathogenic not only to penaeid shrimps, but also to a wide range of hosts which include marine crabs , copepods, freshwater crabs and prawns. Main objective of this study was detection and identification of white spot virus from wild shrimp and crabs population on the coastal waters of Hormozgan Province.The samples were collected from three area seasonally include: coastal waters of Qeshm Island, Hengam Island and Jask. In this survey have been examined 1080 shrimp from each species of P.indicus, P.semisulcatus, P.merguiensis, Metapenaeus affinis and 1080 crabs (gill organs) by PCR and histopathological methods. Diagnostic kit for this survey have been prepared from Genesis Biotechnology CO.in Malaysia, so called "Single-Tube Nested PCR for WSSV". The analysis results revealed that all samples which examined from these area were free from WSV. Following PCR tests that were negative for all samples so no observed any damages of histology due to WSV on gills

A robust optimization approach for the production-routing problem with lateral transshipment and outsourcing

Despite the fact that there is a large body of literature on the Production Routing Problem (PRP), we were struck by the dearth of research on outsource planning and lateral transshipment. This paper presents a mixed-integer linear programming model for incorporating outsourcing, lateral transshipment, back ordering, lost sales, and time windows into production routing problems. Then a robust optimization model will be introduced to overcome the detrimental effects of demand uncertainty. Considering the scale and complexity of the suggested problem, addressing it in a reasonable time was a challenge. Therefore, three matheuristic algorithms, including Genetic Algorithm (GA), Simulated Annealing (SA), and Modified Simulated Annealing (MSA), are developed for solving large-scale problems. Eventually, computational experiments on disparate instances are performed, and the results show the effectiveness and efficiency of the proposed algorithms. In other words, our recommended algorithms outperform the CPLEX solver in terms of the quality and time of obtaining the solutions
