Face à un appauvrissement des sols et une irrégularité des pluies du fait du changement climatique, une étude a été entreprise sur la culture du maïs au Centre-Nord de la Côte d’Ivoire. Elle avait pour objectif d’évaluer l’influence de quatre types de fumures sur le potentiel agronomique de deux génotypes de maïs (Zea mays L.) en cas de contrainte hydrique de fin de cycle et d’infertilité des sols. Le dispositif expérimental a été un split-plot, dont le premier facteur a été les fertilisants et le second, la variété. Les résultats ont montré que les fumures ont influencé les durées des phases végétative et reproductive en plus du rendement. Les fumures fiente de poulet et déjection de boeuf ont permis d’obtenir un rendement qui est égal à six fois celui obtenu avec le témoin de la variété à grain noir malgré la contrainte hydrique. Aussi, la fumure fiente de poulet a eu une tendance à réduire le cycle de culture et favoriser une meilleure croissance et un bon développement des plantes. L’utilisation de ces fumures en culture du maïs, pourrait constituer une alternative aux conséquences drastiques du changement climatique.

English Title: Effect of four types of fertilizers on the growth and productivity of two maize genotypes (Zea mays L.) in the event of late planting in Korhogo in North-Central Côte d'Ivoire

English Abstract

Faced with soil depletion and irregular rains due to climate change, a study was undertaken on maize cultivation in North-Central Côte d'Ivoire. Its objective was to assess the influence of four types of manure on the agronomic potential of two maize genotypes (Zea mays L.) in cases of water stress and soil infertility. The experimental set-up was a split-plot, the first five-level factor being fertilizers and the second two-level factor being variety. Observations were made on phenology, growth parameters and yield. The results showed that manure influenced vegetative and reproductive time, growth parameters and yield. In terms of yield, chicken droppings and beef droppings were the most effective. They yielded six times the yield obtained with the black-grain variety control despite the water constraint at the end of the cycle. Also, chicken manure has had a tendency to reduce the growing cycle and promote better growth and plant development. The use of these manure in maize cultivation could be an alternative to the drastic consequences of climate change.

Published: June 2020

Biochemically wound healing process is promoted by active agents which compose aqueous and alcohol herbal extracts and those components act synergistically. We propose in this study four methods of soft aqueous extraction (A, B, C, D) of Ageratum conyzoides Linn. leaves, a well-known west african plant for its wound healing properties. Our main objective was to know which of the extraction methods would allow us to obtain specifically tannins and flavonoids. We also investigated which types of flavonoids extracted could inhibit serine proteases like thrombin or serine proteases present in bacterial and then being bactericide. Ageratum conyzoides Linn. samples were collected in the beginning of the raining period in May 2019 in two regions of Togo. After aqueous extractions, TLC and HPLC-ESI+-QTOF analysis were done. Chromatographic fingerprints obtained were quite similar for the four extracts investigated. However, additional spots with different colors appeared for the B extract. Flavonoids were revealed by the numerous colors of spots observed on the chromatograms. Superposing HPLC-ESI+-QTOF chromatographic profiles of the four extracts, we deduced that our proposed extraction methods lead to same chemical compounds but B extract contained higher concentrations of later substances. Identified molecules belong to terpernoids and flavonoids classes.Keywords: Ageratum Conyzoides Linn., Aqueous extractions, Biomolecules, Wound healing.

L’obésité est liée aux complications cardiovasculaires et métaboliques chez les adolescents. Cette étude vise à apprécier les effets d’un programme d’exercices physiques combinés à une éducation nutritionnelle sur la composition corporelle et le profil lipidique. Il s’agit d’une étude d’intervention qui a concerné cinquante adolescents obèses âgés de 14 à 18 ans repartis en deux groupes : groupe contrôle vs groupe intervention. Le groupe d’intervention a été soumis à un entrainement de 12 semaines et une intervention nutritionnelle. Les différentes mesures ont été effectuées au début, à 6 semaines et après l’intervention. Les résultats ont montré une diminution significative des valeurs de tour de taille (4,33%), du pourcentage de graisse (4,82%), des taux de LDL cholestérol (p = 0,01), du cholestérol total (p ˂ 0,001), des triglycérides (p ˂ 0,001) et de la glycémie à jeun (p ˂ 0,001) après l’intervention. Une augmentation significative du taux de HDL cholestérol (p = ˂ 0,001) a été aussi observée. Nos résultats indiquent que l’aérobic et le renforcement musculaire associés à une intervention nutritionnelle sont suffisants pour améliorer quelques indicateurs de santé. Ce programme peut probablement être utilisé comme traitement non pharmacologique dans la prévention et la prise en charge des adolescents obèses.Mots clés : Activité physique, éducation nutritionnelle, composition corporelle, lipides sanguins, école, Congo.

English Title: Evaluating the effectiveness of a training program combined with nutrition education in obese adolescents

 

Obesity is linked to cardiovascular and metabolic complications in adolescents. This study aims to assess the effects of a physical exercise program combined with nutritional education on body composition and lipid profile. It is an intervention study that involved fifty obese adolescents aged 14 to 18 years divided into two groups: control group vs. intervention group. The intervention group underwent 12 weeks of training and nutritional intervention. The different measurements were carried out at the beginning, at 6 weeks and after the intervention. The results showed a significant decrease in waist circumference values (4.33%), percentage of fat (4.82%), LDL cholesterol levels (p = 0.01), total cholesterol (p ˂ 0.001), triglycerides (p ˂ 0.001) and fasting blood glucose (p ˂ 0.001) after the intervention. A significant increase in HDL cholesterol (p ˂ 0.001) was also observed. Our results indicate that aerobics and muscle strengthening associated with a nutritional intervention are sufficient to improve a few health indicators. This program can probably be used as a nonpharmacological treatment in the prevention and management of obese adolescents.

Effects of ground granulated blast furnace slag and pulverized fuel ash on rheology of concrete
Authors: Bature A.S. , Khorami M. , Lawan A.
Published: June 2020

The rheology of concrete containing Pulverized Fuel Ash (PFA) and Ground Granulated Blast Furnace Slag (GGBS) has been scarcely studied and reported, despite their increase application as Supplementary Cementitious Materials (SCM) that drives improvement of sustainability of the construction industry. This work studied the effect of these SCMs and Superplasticizer proportions on rheological properties of concrete using rate controlled concrete rheometer. Two groups of mixes containing replacement or addition on mass basis using either PFA or GGBS or their combinations were derived from the control mix. The dynamic yield stress, plastic viscosity and 28 day compressive strength of the control mix are 1258 Pa, 6 PaS, and 40.5 MPa respectively. The results of the rheology tests of the various binary mixes (PFA and Portland cement) and ternary mixes (Portland cement, PFA and GGBS) structural concrete shows wide disparity in the measured rheological parameters. The results show that the decrease in dynamic yield stress of the ternary mix containing 20% GGBS is 4.1%, whereas the decrease in dynamic stress of the ternary mix containing 20% PFA is 35.9% compared to the control ternary mix. The high volume Portland cement replaced ternary concrete can therefore be effectively characterized as a workable and pumpable concrete.

Published: June 2020

In this present study transesterification of used vegetable oil (UVO) using synthesized activated anthill as catalyst was investigated. The catalyst was prepared via calcination process, characterized by Brunauer-Emmett-Teller (BET), X-ray diffraction (XRD) and Fourier transform infrared (FTIR) techniques. From the BET analysis; calcination temperature has a positive impact on the textural properties. The XRD shows that the catalyst is crystalline in nature. Fatty acid methyl esters (FAME) was produced using thermally activated anthill as catalyst. The optimal FAME yield of 94.85 % was obtained at Methanol/Oil (M/O) 9:1, catalyst loading 1.5 wt%, reaction temperature of 65 ᵒ𝑪 and reaction time of 2 h. The physico-chemical properties of UVO – FAME produced was found to be within the American Society for Testing and Methods (ASTM). Hence, the study reveals that used vegetable oil catalyzed by novel activated anthill could be an effective feedstock to produce sustainable energy.

Investigating the lateral stability of three-wheeled scooter taxi due to tyre-road forces
Authors: Asuelinmen G.A. , Ojolo S.J. , Ajayi O.O.
Published: June 2020

Three-wheeled scooter taxi (TWST) that is currently prevalent in developing countries, is fuel efficient and cheap. It is used mainly for commercial purposes, also as a means of reducing unemployment and tackling poverty. However, the vehicle is unstable and prone to accidents due to its design configuration. The aim of this research work is to investigate the lateral stability of TWST due to Tyre-Road Forces. Therefore, lateral stability equations for three-wheeled vehicle (TWV) were developed and used in the analysis of TWST based on parametric values obtained from static test. The results showed that the vehicle is stable with respect to lateral stability, which is in line with what was obtained from literature, thereby validating the models with the driver alone. However, with two or more occupants the vehicle became unstable. Possible ways of eliminating this instability were discussed. The static test procedure, if adopted and legislated upon, would significantly enhance safety of life and properties of stakeholders in developing countries.

Analysis of factors that influence the calorific value of mangrove wood for electricity generation using split- split plot design
Authors: Omidih L.A. , Omotehinse S.A.
Published: June 2020

The issue of energy shortage in Nigeria has been a concern for both the Nigerian government and the people for the past four decades. In many  third world countries and indeed many parts of Africa, Nigeria inclusive, electricity is abysmally in short supply. This is somehow due to over  dependence on fossil fuels which accounts for greater part of the power generation but with an unreliable supply chain. This study seeks to apply Split-Split plot experimental design as statistical tool to analyze factors that influence the calorific value of mangrove wood during combustion for  electricity generation. The combustion process was carried out at the National Centre for Energy and Environment, University of Benin. Each of the wood samples was pulverized to enable easy combustion. Bomb calorimeter was used to carry out the test on the various pulverized wood samples. The calorific value of each sample was collected and recorded in three replications. The result of the study shows that the raw materials location has differential treatment effect on the calorific value of the raw material type employed. It was discovered that the differential treatment effect produced by the raw materials type is largely due to the location of the raw materials. The result obtained from the analysis also shows interaction  between the raw materials location and the different raw material types to influence the calorific value of the white mangrove, red mangrove and rubber wood used in this study.

Effect of atmospheric impairments on ku-band free-to-air digital satellite television signals in Lagos State
Authors: Gbenga-Ilori A.O.
Published: June 2020

With the rapid deployment of free-to-air satellite television, there is an increasing need for an accurate propagation prediction tool for satellite link planning. This paper presents an evaluation of deterministic propagation model that is best for the analysis of satellite signal quality at Ku-band in Lagos state, Nigeria. The paper aims at comparing accurate measurements of channel-to-noise (C/N0) and bit error rate (BER) taken at six locations within Lagos state with simulation results derived from the Institut für Rundfunktechnik (IRT) model and modified irregular terrain model (ITM) deterministic propagation models. The work considered the effect of the type of modulation scheme and error correction code used on the C/N0 and BER received using these deterministic propagation models. Results show a deviation of 0.732 dB and 0.285 dB from C/No measurements using the IRT and modified ITM models respectively. This work shows that at more than 1% of the time, both models performed well when compared with measurements. However, at less than 1% of the time, which accounts for periods of heavy rainfall, the modified ITM model performed better. The paper also shows that when error correction code is not used with the modulation scheme deployed, the BER increases rapidly and the effect of using a higher alternate modulation symbol is not evident on achievable data rates.

Keywords: Bit error rate, deterministic propagation models, Ku-band, satellite link planning

This study reports the determination of some heavy metals’ concentration in soil and groundwater around refuse dumpsites in five locations in Ibadan Metropolis, Nigeria. Five samples were collected from each soil and ground water locations and analysed for heavy metals(Cd, Co, Pb, Cr, Zn, Mn and Ni)using Atomic Absorption Spectrophotometry. The soil samples were obtained in triplicates at 25cm depth intervals whereas the water samples were obtained from hand dug wells less than 10 m deep. The range of the values of heavy metal concentrations obtained in water is Co (0.01-0.04), Pb (0.01-0.02), Cr (0.02-0.05), Zn (0.40-0.70), Mn (0.02-0.05) and Ni (0.02-0.05), but Cadmium was not detected. The concentrations of Pb and Ni in ground water obtained from Arapaja, Aleshinloye and Alafara were higher than the World Health Organization (WHO) and Standard Organisation of Nigeria (SON) limits. The results obtained showed that the concentrations of Cd, Co, Pb, Ni and Cr in soil exceeded the WHO and SON permissible limits. However, Zn and Mn were below the limit.

State of play on the use of building construction standards in Congo-Brazzaville
Authors: Ndongo A.S. , Malanda N. , Bahouayila B.
Published: June 2020

This work aims to assess the existence and use of local standards in the field of building construction in Congo-Brazzaville. Surveys were carried out among construction companies, design offices and construction control firms operating in the construction industry. The results show that, overall, design offices, control or engineering consulting firms have more knowledge about the existence of construction standards, unlike construction companies. Indeed, it appears from this study that the probability of knowing of the existence of Congolese standards in construction control firms and construction companies is very low compared to engineering firms. The evidence provided by our sample also shows that structures involved in technical studies and real estate expertise are less aware of the existence of Congolese standards. Also, we note that the rate of knowledge about the existence of Congolese standards is more recorded at the level of structures that use foreign standards (16.90% against 9.09%), than those that do not use them. These structures also have knowledge of the effects (negative or positive) on the use of these foreign standards on construction (22.22% versus 3.57%) in Congo. Construction professionals must take into account certain technical specificities related to natural and social phenomena in the implementation of their construction projects in order to avoid early depreciation of the works carried out.

Influence of production systems and sex on nutritional value and meat quality of native Malawian Muscovy ducks
Authors: Tanganyika J , Webb E.C.
Published: June 2020

This study was conducted to assess effects of production systems and sex on nutritional value and meat quality of native Malawian Muscovy ducks. One hundred twenty ducks were randomly assigned to either an intensive (IS), duck-rice integration (DR) or free-range (FR) production system. A starter ration containing 20% crude protein and a finisher containing 17% crude protein were fed to ducks in IS (1 to 4 weeks), and provided as a supplement to ducks in DR and FR (5 to 10 weeks). Feed and water were offered ad libitum. At 10 weeks of age, 16 ducks per treatment were selected randomly, slaughtered and chilled at 4 °C for 24 hours. Carcass temperature, pH and meat colour were measured at 45 min, and at 3, 6, 12 and 24 hours post mortem. Tenderness, cooking loss, proximate and mineral composition were determined 24 hours post mortem. Production system and sex had no effect on carcass temperature, pH and proximate composition of duck breast meat. However, production system affected tenderness and mineral composition of the meat and sex influenced moisture and tenderness. Males were moister and had less tender meat than females. Carcasses from ducks in the FR system contained more zinc, copper, manganese, and potassium, but less iron while those in IS had the lowest mineral content of the three production systems. Thus, DR can be adopted to improve the current FR system of native Malawian Muscovy duck production with supplementation to produce duck with acceptable mineral composition and better meat quality.

Published: June 2020

This study compared growth and carcass traits of 2 medium-growth crossbred, 4 slow-growth crossbred, 1 commercial slow-growth and 1 commercial fast-growth broiler strains raised in indoor and free-range production systems. One hundred twenty chicks of each strain were raised in each production system. Chicks were raised in indoor pens at a density of 10 chicks per m2. From day 29 until slaughter at 84 days of age, chicks in the free-range system were given outdoor access through doors that were open between 8.00 - 17.00 hours. The study found live weight, feed efficiency, and mortality were significantly affected by strain. However, no significant differences were found between the production systems. Outdoor access varied significantly among strains, with the commercial high-growth and medium-growth crossbred strains making less use of outdoor areas. In terms of performance traits, none of the strains showed any significant differences in performance between the indoor and free-range production systems. However, significant differences among the strains in carcass traits, pH, and colour values of thigh and breast meat were observed in connection with differences in growth rate. Moreover, carcass and breast yields were greater in fast and medium-growth broilers, while ratios of edible inner organs were greater in medium and slow-growth broilers.

Genetic improvement of sow longevity and its economic impact on commercial pork production
Authors: Mote B.E. , Serenius T.V. , Supakorn C , Stalder K.J.
Published: June 2020

Sow longevity (sow productive lifetime) plays an important role in economically efficient piglet production. Direct selection for sow longevity is not commonly practiced in any pig-breeding program. In recent years, an increased number of peer reviewed articles addressing the economic impact, genetic parameter estimates, and genomic information (including markers and single nucleotide polymorphisms for sow longevity) have been published in the scientific literature. The studies in the literature indicate that sow longevity is a complex trait having economic value and is an animal well-being concern for commercial pork producers. Studies have concluded that sufficient genetic variation exists so that selection to improve sow longevity should be effective. Unlike the dairy industry, the primary parent animal used in the swine industry is a crossbred female, typically F1 (Landrace X Large White or Yorkshire). Sow longevity has shown to be genetically related with prolificacy and leg conformation traits. Sow longevity seems to be the ideal trait to utilize genomic selection when attempting to improve the trait. The genetic correlation between purebred and crossbred sow longevity is low. Since the crossbred sow is the breeding objective, phenotypic data from the crossbred females should ideally be used when estimating the breeding values for sow longevity that are used in the indexes to evaluate nucleus animals. Genomic selection is best suited for sex-limited traits, traits expressed later in life, and many animals do not reach some defined end-point parity, sow longevity seems ideally suited to be evaluated using the latest genome enabled selection technology.

Effect of different levels of supplementation after weaning on beef heifer development
Authors: Foster L.A. , Fourie P.J. , Neser F.W.C.
Published: June 2020

The purpose of the study was to identify a cost-effective supplementation regimen to rear replacement heifers on transitional Cymbopogon-Themeda veld. A total of 120 Drakensberger heifers aged 6 - 7 months were randomly allocated to three supplementary treatment groups from 2011 - 2014. A three-phase supplementation programme was used while the production year was divided into three periods, namely summer (wet season) (approximately mid-December to March), winter (early dry season) (April to July), and late winter (late dry season) (August to approximately mid-December). The late winter treatments consisted of three levels of supplemental crude protein (CP), a percentage of protein derived from non-protein nitrogen (NPN) and metabolizable energy (ME), namely T1: 306 g CP/kg (47.4% NPN) + ME 7.4 MJ/kg; T2: 329 g CP/kg (70.72% NPN) + ME 6.89 MJ/kg; and T3: 475 g CP/kg (95.86% NPN) + ME 2.4 MJ/kg. In summer, T1 was supplemented with 164 g CP/kg (7% NPN) + ME 9 MJ/kg + 13 g P/kg; T2 with Voermol Superfos with 150 g CP/kg (13.6% NPN), ME 0 MJ/kg, and 50 g P/kg; T3: 0 g CP/kg, ME 0 MJ/kg, and 60 g P/kg. The traits were nutrient intake, supplement cost, mean bodyweight, weight gains/losses and mean BCS. The study concluded that feeding replacement heifers to traditional bodyweight increased development costs without improving production sufficiently. Veld that is in good condition together with a mineral (60 g P/kg) supplement in the wet season and a protein and mineral supplement (96% NPN) in the dry season gives the highest economic return.

Published: June 2020

Carcass condemnation is a problem in the South African beef industry, but the causes and risk factors have not been studied or quantified. Better understanding of the cumulative incidence and causative predictors of carcass condemnations could assist in improving cattle management during transportation, preslaughter and lairage in high-throughput abattoirs. This study was conducted to investigate the main causes and predisposing factors of carcass condemnation at a large high-throughput cattle abattoir during postmortem inspections from January to December 2010. The experimental design included the effects of season, breed type, and sex, and their interactions on the cumulative incidence of carcass condemnations, and the causes of partial and whole carcass condemnations and the impact on carcass yield. The model was based on the presence of defects. Thirteen diseases and defects were evaluated in various breeds, sexes and seasons. The cumulative incidence of partial and complete carcass condemnations was 9.5%.The most important causes were peritonitis and pleuritis, soiling and bruising, Almost half of these carcass condemnations were due to soiling and bruising, which can be addressed by implementing better abattoir management during transportation, pre-slaughter and lairage. The cumulative incidence of parafilaria occurred mostly in spring and summer. Measles, intramuscular haemorrhage and wet carcass syndrome occurred mostly in winter. The cumulative incidence of the other defects had a negligible effect. Numerically the greatest carcass weight losses subsequent to partial condemnations were because of intramuscular haemorrhage and bruising.

Published: June 2020

Naringin is a major flavanone derivate that has many important biological functions in animals. However, its effect on pigs is unknown. The aim of this study was to investigate the effect of naringin supplementation on performance, carcass traits, meat quality and oxidative stability in finishing pigs. Ninety-six pigs, with an average initial body weight of 66.2 ± 0.63 kg, were randomly divided into four groups. One group was fed a basal diet without supplementation (control), and the three others were fed diets supplemented with 0.5, 1.0 or 1.5 g naringin /kg DM of feed for 50 days. Each treatment was replicated six times with four pigs per replicate. Feed and water were available ad libitum. The 0.5 g/kg naringin treatment group had an improved loin eye muscle area, reduced serum triglycerides and were leaner compared with the other groups. Pigs in the 1.5 g/kg naringin treatment had higher pH45min values and inosine monophosphate concentrations, and lower MyHC IIb mRNA expression in muscle than the other groups. MyHC IIa mRNA expression was significantly up-regulated in all naringin-supplemented diet groups. Naringin significantly increased superoxide dismutase (SOD) activity and total anti-oxidative capacity in meat, as well as SOD and glutathione peroxidase activity in the liver. These results indicate that the dietary addition of naringin at 0.5 g/kg improved carcass characteristics, while 1.5 g/kg improved the oxidative stability and pork quality in finishing pigs.

Anopheles gambiae s.l. insecticide susceptibility status in Umudike, Ikwuano LGA, Abia State, Nigeria
Authors: Ekedo C.M. , Ukpai O.M.
Published: June 2020

This study was conducted in order to determine the insecticide susceptibility status of Anopheles gambiae in Umudike, Abia State, Nigeria. Larval and pupal stages of An. gambiae mosquitoes were collected from different points within Umudike, and reared to adult stage in the laboratory. The adults that emerged were tested on four types of WHO bioassay test papers impregnated with recommended diagnostic concentrations of 4% DDT (Organochlorines); 0.1% bendiocarb (Carbamates); 0.25% Primiphos-methyl (Organophosphates); and 0.05% Deltamethrin (Pyrethroids) procured from National Abovirus and Vector Research Institute Enugu. Twenty 10% sugar solution fed female Anopheles gambiae mosquitoes aged 3-5days were used for the bioassay which was replicated four times with two control of same population without insecticide treatment. Knockdown was recorded at five minutes post-exposure, and then at 10 minutes interval for 1 hour and then maintained for 24 hours post-exposure on 10% sugar solution, after which a final mortality was recorded. The Knockdown Times (KDT50 and KDT90) were determined by Probit analysis. An. gambiae was resistant to DDT, primiphos-methyl and Deltamethrin with 24 hours post exposure percentage mortalities of 4.65, 11.85, and 24.83 respectively.In contrary the mosquitoes were susceptible to bendiocarb which killed 98.88% of the mosquitoes 24 hours after exposure. Bendiocarb is hence recommended as the most effective insecticide for the control of Anopheles gambiae in Umudike, while there were need for the investigation of the mechanism behind the resistance displayed by this mosquito. Furthermore, routine surveillance of insecticide susceptibility/resistance in mosquito population is advocated in line with integrated vector control strategy.

Real estate boom in Chile and fundamentals on house prices
Authors: Aguilera Alvial C.
Published: June 2020

This article studies the fundamentals of housing prices based on the Real Index of Housing Prices (IRPV), given that in recent times in Chile there has been a sustained increase in price levels and seeks to find evidence on the existence of a possible speculative bubble in the real estate market. Following the methodology of various Chilean and international authors, the Engle & Granger Co-integration methodology was applied. Furthermore, the results of the previous methodology were compared using the Johansen Co-integration test. Then a method to find structural breaks is applied. As a result, evidence is found to not reject the existence of a bubble in the real estate market. It is found that only interest rates co-integrate in the long term with the evolution of house prices, while the other fundamentals present a spurious relationship.

Daunting for users to formulate precise queries and search correct answers. Therefore, approximate matching is introduced to trot out the problem in respondent users’ queries, and this matching might be addressed by 1st reposeful the structure and content of a given question, so longing for answers that match the relaxed queries. Ranking and returning the foremost relevant results of a question became the foremost widespread paradigm in XML query process. However, the present proposals don't adequately take structures into consideration and those them so lack the strength to elegantly mix structures with contents to answer the relaxed queries. To handle this drawback, we have a tendency to 1st propose a classy framework of question relaxations for supporting approximate queries over XML information. The answers underlying this framework aren't compelled to strictly satisfy the given question formulation, instead they will be based on properties inferable from the initial question. we have a tendency to then develop a unique top-k retrieval approach.

Generally every patient have unique login to update and track their health reports. Doctors prefer diet control and tablets to control the diabetics. If diabetics are uncontrollable doctor prefer walking shoes. These shoes have GPS tracker and integrated chip, which count the steps, taken by the patient. (i.e.) for example 5steps is approximately 1Km. Using the step count, patient’s blood sugar level checked and maintained. Patient step can be graphically represented and stored in the cloud and the doctor can view the reports. With the report doctor can easily identify the blood sugar level. If step count is higher, sugar level become low. GPS tracker help in location tracking as a result accurate data of patients is stored in the cloud and evaluated the result is sent to the patients and also to the doctor using short message services.
Efficient RSU Selection Approaches for Load Balancing in Vehicular Ad Hoc Networks
Authors: Huang Chi-Fu , Jhang Jyun-Hao
Published: June 2020

Due to advances in wireless communication technologies, wireless transmissions gradually replace traditional wired data transmissions. In recent years, vehicles on the move can also enjoy the convenience of wireless communication technologies by assisting each other in message exchange and form an interconnecting network, namely Vehicular Ad Hoc Networks (VANETs). In a VANET, each vehicle is capable of communicating with nearby vehicles and accessing information provided by the network. There are two basic communication models in VANETs, V2V and V2I. Vehicles equipped with wireless transceiver can communicate with other vehicles (V2V) or roadside units (RSUs) (V2I). RSUs acting as gateways are entry points to the Internet for vehicles. Naturally, vehicles tend to choose nearby RSUs as serving gateways. However, due to uneven density distribution and high mobility nature of vehicles, load imbalance of RSUs can happen. In this paper, we study the RSU load-balancing problem and propose two solutions. In the first solution, the whole network is divided into sub-regions based on RSUs’ locations. A RSU provides Internet access for vehicles in its sub-region and the boundaries between sub-regions change dynamically to adopt to load migration. In the second solution, vehicles choose their serving RSUs distributedly by taking their future trajectories and RSUs’ loading information into considerations. From simulation results, the proposed methods can improve packet delivery ratio, packet delay, and load balance among RSUs.
Free Vibration Frequency of Thick FGM Circular Cylindrical Shells with Simply Homogeneous Equation by Using TSDT
Authors: Chih-Chiang Hong
Published: June 2020

The objective of this study is to provide the frequency solutions of free vibration in thick FGM circular cylindrical shells by mainly considering both shear correction coefficient and nonlinear coefficient term. This paper investigates the effects of third-order shear deformation theory (TSDT) and the varied shear correction coefficient on the free vibration of thick functionally graded material (FGM), the circular cylindrical shells with simply homogeneous equation under thermal environment. The approach of derivations are given as follows, the varied value of shear correction coefficient is included in the simple homogeneous equation. The nonlinear term of displacement field of TSDT is also included to derive the simply homogeneous equation, some reasonable simplifications in the elements of homogeneous matrix under free vibration of thick FGM circular cylindrical shells are assumed, thus, the natural frequency can be found. Three parameters effect on the frequency of thick FGM circular cylindrical shells are computed and investigated, they are nonlinear coefficient c1 term, environment temperature and power law index. There are some main conclusions obtained, generally the natural frequency results are in decreasing value with the mode shape numbers for the thicker circular cylindrical shells. The values of natural frequencies are also affected by the nonlinear coefficient term.
