Monitoring of Pesticide Residues in Imported Datepalm Fruits in United Arab Emirates

The occurrence of pesticide residues in representative samples collected from imported dates palm fruits during 2020 to United Arab Emirates (UAE) was investigated to ensure compliance with the standard specifications and requirements by the regulatory and supervisory authorities, maintain the health and safety of consumers and improve food safety. An accurate, rapid, and reliable method for the simultaneous determination of pesticide multi-residues in 230 samples imported dates by liquid chromatography coupled with tandem mass spectrometry (LC–ESI (+)-MS/MS) operating in multiple reaction monitoring (MRM) mode and modified quick, easy, cheap, effective, rugged, safe (QuEChERS) method was used. The performance of the analytical method was validated in accordance with EU SANCO guidelines (SANTE/12682/2019) for monitoring pesticide multi-residues to check compliance with existing regulations, especially for European Community. Residues level of 343 compounds were determined in 230 samples. Results indicated that the percentage of samples with residues above the maximum residue levels (MRL) was 4.34% in dates samples, whereas samples with residues within MRL were 7.39% in dates samples. A total of 230 samples of 88.26% were free from detectable residues. Out of the 343 pesticides tested, 11 pesticides were found above the limit of detection, according to UAE, Codex, and European regulations. The main purpose of this work is to inform citizens and traders who have concerns about food safety on the capability of the MOCCAE on quality assurance regarding pesticide residue in imported food.
Reflective Impulse Radios: Principles and Design

Emerging wireless sensor networks display a severe asymmetry between the up and down links. An alternative communication architecture, reflective impulse radio, is proposed to address such design challenges. It operates from the principles of passive transmission and pulse based modulation, readily used in radio frequency identification (RFID) and ultra wide-band (UWB) technologies respectively. By employing both schemes in conjunction however, it achieves ultra low power consumption and high data rate simultaneously.This dissertation begins by examining future wireless sensor applications and presenting the link asymmetry. The alternative architecture is then introduced and its operation principles explained. A step-by-step design procedure follows, accompanied by the implementation of a miniature biomedical implant transmitter as a design example. Potential challenges and mitigation techniques are also discussed. Key advantages of the proposed architecture include ultra low power consumption, simple circuitry (hence high reliability and low cost), and broad range of scalability. Measurement results of the biomedical example are subsequently presented, before a short conclusion is given in the end.While originated for wireless sensor networks, the proposed architecture can be applied to many other applications facing similar communication challenges.
Development of ‘Bondarmine’ disinfectant formulation and study of its Tuberculosis effect

The article presents the results of studying the bactericidal properties of the disinfectant ‘Bondarmin’, consisting of potassium peroxymonosulfate, sulfonol (surfactant), adipic acid (hexanedioic acid), and sodium chloride. The active component of the preparation is potassium peroxymonosulfate (KHSO5), which being HSO5 ion in solution, has an oxidizing effect on the cysteine moieties of microorganism proteins. The highest oxidation-reduction potential is achieved in an acidic medium (pH 2.0–2.3), which is provided by a buffer additive — adipic acid, as well as additionally the presence of sodium chloride in the solution, which creates a high ionic force of the solution, and therefore contributes to the high osmotic pressure of the solution — important factors of biocidal action. KHSO5 slowly oxidizes chlorides to chlorine, which has an additional bactericidal effect (high availability of disinfectant to internal surfaces). Studies on the bactericidal properties of the ‘Bondarmin’ disinfectant were carried out in accordance with the methodological recommendations ‘Determination of bactericidal properties of disinfectants, disinfection and control of its quality in tuberculosis of farm animals’. Experimental studies have established bactericidal effect of disinfectant ‘Bondarmin’ in concentration 1.0% per exposure of 3 hr in relation to atypical mycobacteria M. fortuitum and tuberculosis pathogens M. bovis and M. avium
Effect of Stirring Time on Sodium Silicate Synthesis From Mount Kelud Volcanic Ash

This study performed the synthesis of sodium silicate from the volcanic ash of Mount Kelud with various stirring time in the sodium silicate synthesis process. Synthesis of sodium silicate was carried out using alkaline extraction at low temperature. This method is based on the solubility of silica under alkaline conditions and is proven to be more effective than the smelting method. The dissolution of silica contained in the volcanic ash of Mount Kelud was carried out using NaOH solution to form a Na2SiO3 solution. This process also studied the effect of stirring time on the amount of dissolved silica, with the stirring time of 0.5; 1; 1.5; 2; 2.5; 3 and 4 hours. The dissolved silica levels were tested using AAS. The amount of dissolved silica increased sharply with the longer length of stirring time, however for a stirring time of more than 2.5 hours, the dissolution was slow. The study revealed that the optimal result time was obtained from the stirring time of 2.5 hours with dissolved silica content of 19.82%. Keywords: volcanic ash, silica, sodium silicate, stirring time
The Key to Health and Happiness –Measurements show that not only is it Important What You Eat and Drink, it is Equally Important What You Think

The Russians patented “torsemeter” and measured the spinning of the human donut-shaped nonlinear electromagnetic field (NEMF). They found that positive emotions make the human donut spin faster clockwise, while negative emotions make it spin counterclockwise. Measurements with our patented sensitive energy meter showed that when people think about the happiest moments of their life, the energy of their NEMF increases and is better balanced, which means they are healthier. When people think about the saddest moments of their life, the energy of their NEMF drops down and the balance becomes worse because their genetically inherited weak organ, drops in energy maximum. This would be the organ to develop a chronic disease first under distress or negative thinking. According to nonlinear physics, vortices spin clockwise and suck energy in. Since positive emotions or thinking make the donut-shaped NEMF spin clockwise faster, the spinning clockwise vortex on top of the head obviously sucks energy in, which explains the measured increased energy on top of the head, the increased total energy, and the improved energy balance. Since negative emotions or thinking make the donut spin faster counterclockwise, the spinning counterclockwise anti-vortex on top of the head would release energy, which explains the decreased total energy at negative thinking. Thus, to be healthy, not only is it important what you eat and drink – it is equally important what you think.

Silicon carbide JFET radiation response

Total dose and neutron-induced displacement damage effect studies are reported for n-channel, 2- mu m channel length, depletion mode junction-field-effect-transistors (JFETs) fabricated on 6H-silicon carbide. Very little effect was observed on device characteristics for total dose ionizing radiation for doses up to 100 Mrads(Si), but the devices were significantly degraded after a neutron fluence of 10/sup 16/ n/cm/sup 2/. A value of 4.5+or-0.5 carriers/cm/sup 3//neutrons/cm was obtained for the carrier removal rate from neutron irradiation. The results offer promise for SiC devices to be used in applications which combine high-temperature and radiation environments, where the use of Si and GaAs technologies is limited. >
The influence of excessive consumption of liquorice on phenprocoumon (Marcumar®): a case report

Here, the case of a 92-year-old female patient, who was diagnosed with atrial fibrillation and treated with phenprocoumon (Marcumar®), is reported. Pre-existing comorbidities were arterial hypertension, coronary heart disease, diabetes mellitus type 2, mild senile dementia and renal insufficiency. Despite treatment with phenprocoumon (Marcumar®), the patient experienced an ischaemic stroke. Her measured international normalized ratio (INR)-values during the months before the stroke were within the therapeutic range of 2–3, then suddenly decreased to 1.25. A retrospective inquiry failed to identify any significant changes in behaviour or therapy adherence, other than the consumption of 1.5 kg (3.3 lb) of hard-boiled candy liquorice in the days leading up to the stroke. The sudden decrease in INR-values may be explained by the influence of liquorice and its compounds on the pharmacokinetics of phenprocoumon (Marcumar®). In this context, the most important factors are the susceptibility of vitamin K antagonists to nutrition or metabolic irregularities, the influence of liquorice on the function of isoenzymes of the cytochrome P450 family that may lead to reduced bioavailability of phenprocoumon, and the influence of liquorice on peroxisome proliferator-activated receptor alpha transactivation.
Wavelets and perfect reconstruction subband coding with causal stable IIR filters

We show for the first time that it is possible to have a large family of perfect reconstruction subband coding filter banks, which are causal and IIR both at the analysis and at the synthesis ends. Complete parametrization of such classes of filters leading to design methods are given. Parametrizations in frequency domain terms as well as in terms of state space descriptions of filters are provided for better numerical implementation of design methods. The development is valid for two-band as well as for multiband subband coding schemes. The iterated filter banks are shown to give rise to a new family of biorthogonal version of continuous wavelets, the scaled and dilated version of which represents arbitrary square integrable signals. Dilation factors larger than two are implicit in the development resulting from the fact that we consider multiband subband coding schemes. >
AN ANT COLONY APPROACH TO THE ORIENTEERING PROBLEM

ABSTRACT This paper develops an ant colony optimization approach to the orienteering problem, a general version of the well-known traveling salesman problem with many relevant applications in industry. Based on mainstream ant colony ideas, an unusual sequenced local search and a distance based penalty function are added which result in a method that is convincingly shown to be the best heuristic published for this problem class. Results on 67 test problems show that the ant colony method performs as well or better than all other methods from the literature in all cases and does so at very modest computational cost. Furthermore, the ant colony method is insensitive to seed, problem instance, problem size and degree of constraint.
Host Restriction Factors Modulating HIV Latency and Replication in Myeloid Cells

In addition to CD4+ T lymphocytes, myeloid cells, and, particularly, differentiated macrophages, are targets of the human immunodeficiency virus type-1 (HIV-1) infection via interaction of gp120Env with CD4 and CCR5 or CXCR4. Both T cells and macrophages support virus replication although with substantial differences. In contrast to activated CD4+ T lymphocytes, HIV-1 replication in macrophages occurs in nondividing cells and it is characterized by virtual absence of cytopathicity both in vitro and in vivo. These general features should be considered in evaluating the role of cell-associated restriction factors aiming at preventing of curtailing virus replication in macrophages and T cells particularly in the context of designing strategies to tackle the viral reservoir in infected individuals receiving combination antiretroviral therapy. In this regard, we will here also discuss a model of reversible HIV-1 latency in primary human macrophages and the role of host factor determining restriction or reactivation of virus replication in myeloid cells.
The Emilia Earthquake: Seismic Performance of Precast Reinforced Concrete Buildings

On 20 and 29 May 2012, two earthquakes of MW5.9 and MW5.8 occurred in the Emilia region of northern Italy, one of the most developed industrial centers in the country. A complete photographic report collected in the epicentral zone shows the seismic vulnerability of precast structures, the damage to which is mainly caused by connection systems. Indeed, the main recorded damage is either the loss of support of structural horizontal elements, due to the failure of friction beam-to-column and roof-to-beam connections, or the collapse of the cladding panels, due to the failure of the panel-to-structure connections. The damage can be explained by the intensity of the recorded seismic event and by the exclusion of the epicentral region from the seismic areas recognized by the Italian building code up to 2003. Simple considerations related to the recorded acceleration spectra allow motivating the extensive damage due to the loss of support.
Does Access to Bank Accounts as a Minor Improve Financial Capability? Evidence from Minor Bank Account Laws

Banking the unbanked is a common policy goal, but should this include access to bank accounts for minors? This study estimates how teenagers' access to bank accounts affects their financial development. Using variation in state laws, we show policies that permit access to independently-owned accounts increase account ownership at age 16 through age 19, although by age 24 those young adults are banked at similar rates to teens who grew up in states that do not allow minors to own accounts independently. Teens who had access to independently-owned accounts use fewer high-cost alternative financial services (like payday loans) through age 20—but are then more likely to use AFS, particularly check-cashing services, from age 21 through 24. Using credit records, we show that access to non-custodial accounts has no effects on credit scores in the short-run, but lower credit scores and more loan delinquencies at ages 21 through 24. While these state laws promote financial inclusion for teenagers, the young people who take on accounts may experience negative consequences in the longer run.
Epilogue

We identify somecommon threads and trends in the observations of hydrological responses to earthquakes. We suggest that seismic energy density is a useful metric for interpreting observations and relating different types of responses. We conclude with a summary of outstanding questions and new opportunities. 14.1 General Framework The interaction between water and earthquakes vividly demonstrates the dynamic nature of the permeability of the uppermost crust, with implications for both earthquakes and groundwater transport. The processes of tectonic deformation and fluid movement are two-way coupled, as shown schematically in Fig. 14.1; i.e., changes in fluid pressure may alter stresses and hence can promote rock failure or accelerate slip on faults; at the same time, deformation and earthquakesmay change pore pressure in the crust, causing changes of the water level in wells, discharge in streams, liquefaction of sediments, changes of groundwater temperature and chemical composition, and may even affect the eruptions of mud and magmatic volcanoes. Figure 14.2 summarizes the magnitude of the reported permeability changes from lab experiments and field observations as a function of strain amplitude. It shows that, first, permeability usually increases after a disturbance, i.e., the ratio between the stimulated and the initial permeabilities is usually greater than 1; second, strain amplitudes as small as 10−6 can change permeability; third, permeability generally increases by less than a factor of ten unless new fractures formor theirwidth increases significantly owing to pressurization of fractures; and fourth, there is no systematic dependence of the magnitude of the reported permeability changes on the strain amplitude, thus the change of permeability cannot be directly related to the applied strain. The results in Fig. 14.2 are also categorized by frequency, with filled boxes indicating frequencies greater than or equal to 10 Hz; everything else, except Faoro et al. (2012), has frequencies between 0.05 and 10 Hz, i.e., the range of seismic frequencies that cause thefield responses.Noobvious frequency-dependence is found either, but more experiments and observations are needed. © The Author(s) 2021 C.

In-line amplifier transmission distance determined by self-phase modulation and group-velocity dispersion

The propagation of an intensity-modulated signal in an optical fiber is numerically analyzed, taking self-phase modulation, group-velocity dispersion, and 2nd-order group-velocity dispersion into account. Transmission distances yielding a prescribed eye-opening penalty are shown to relate to three characteristic lengths: the dispersion length, the 2nd-order dispersion length, and the nonlinear length. These relations, with a slight modification for the signal power, are also found to be valid for in-line amplifier systems, in which each optical amplifier, though adding undesired amplified spontaneous emission, compensates the signal attenuation occurring in the preceding fiber. The resulting relations give us informative guidelines for designing such systems. >
Stability and bifurcation analysis of discrete predator–prey model with nonlinear prey harvesting and prey refuge

In this paper, a discrete Leslie–Gower model with nonlinear prey harvesting and prey refuge is proposed. We prove the existence and stability of an interior equilibrium of the model. In addition, the existence of flip bifurcation and Neimark–Sacker bifurcation at the interior equilibrium is studied by applying central manifold theory and bifurcation theory. Using Pontryagin's maximum principle, we propose an optimal harvesting problem.
THE ROAD SAFETY SITUATION FOR CHILDREN IN BANGLADESH

The incidence of overall child involvement in road accident fatalities in Bangladesh is found to be very high, accounting for about twenty two percent. From an analysis of accident data collected from police with a study period of seven years (1998-2004) it is evident that the involvement of children below 15 years of age in road accident fatalities is much higher than those in other developing countries. This paper aims to discuss the issue of child safety by addressing special needs and requirements of children. Significant reduction of accidents and injuries is possible through a safety conscious and systematic application of countermeasures encompassing traditional three E's- Engineering Enforcement and Education. Also the role of road safety education for children is discussed because it is essential for effective and sustained prevention of accidents and injuries in the longer term. The safety of vulnerable road users, especially children, must be sufficiently catered for in road safety engineering strategies and principles.

Single-stage AC-DC power-factor-corrected voltage regulator with reduced intermediate bus voltage stress

Single-stage power-factor-correction (PFC) circuits usually suffer from high rising intermediate bus voltage stress at light load condition due to power imbalance between the input and output. Also the conversion efficiency is low due to repeated power processing. A single-stage AC-DC power-factor-corrected voltage regulator (PFCVR) is presented for which a portion of the input power is transferred to the output directly after the first power process, resulting in lower voltage stress on the intermediate bus storage capacitor while achieving a high power factor. Conversion efficiency is also improved. In addition, the duty ratio is a function of the load so that the bus voltage decreases when the load is decreased. PFC and fast output regulation are achieved through a proposed simple single-loop voltage feedback controller. Parameters affecting the voltage stress on the intermediate bus capacitor and the input power factor are examined. Experimental results to verify the operation and performance of the converter are also reported.
Theoretical evaluation of GSM/UMTS electromagnetic fields on neuronal network response

Understanding the modalities of interaction of electromagnetic (EM) fields with biological material is a key point in the identification of possible induced effects. An integrated approach to model EM field interaction with biological systems is proposed in this paper. Here, a neuronal network is identified as the biological target. In this paper, for the first time, the possible effects of EM signals related to universal mobile telecommunication system and global system for mobile communication standard on the setup model are investigated.
