Food allergen labeling is an important tool in minimizing the risk of exposure to foods allergens and the resultant adverse effects for individuals with food allergies. Unlike in the industrialized countries, there have been very few studies that have scrutinized food allergen labels and analyzed the robustness of food allergen regulation in developing countries. In the present study, food allergen labeling of 105 supermarket food products in Malawi were evaluated. Furthermore, Malawi's allergen labeling regulation was compared with Codex general standard on labeling, and regulations in force in the E.U, U.S, and Republic of South Africa. About 54.3% of the surveyed products carried the special allergen declaration in addition to the declaration on the list of ingredients, 23.8% used special emphasis (bolding, italic, contrasting color and enlarged font) when declaring allergens on the ingredient list, and 28.6% used precautionary allergen labeling (PAL). Notably, none of the surveyed locally manufactured products had any of these features. However, all the surveyed products complied with the allergen labeling requirements stipulated in Malawi General Standard for Labeling of Prepacked Foods implying that the Malawi standard is not protective enough. Moreover, Malawi's allergen labeling regulation was found to be the least demanding. Although this study is based on data from Malawi, trends and implications for standards development may be applicable to other developing countries especially those in Sub-Saharan Africa. © 2017 Elsevier Ltd

We fabricated sol-gel monoliths using a fast sol-gel (FSG) technique with either UV-curing or thermal-curing, producing highly dense, stable monoliths in a short time. This paper focuses on the preparation and the characterization of different FSG compositions as a function of the inorganic-organic molar-ratio and curing-mechanism. The fabrication of the monoliths was based on three precursors, tetramethoxysilane (TMOS), methyltrimethoxysilane (MTMS), and methacryloxypropyl-trimethoxysilane (MAPTMS). Three series of FSG monoliths with different material compositions were synthesized. The organic content in the final monoliths varied from 17 to 52. weight. percent (wt%). We established the range of precursor's molar-ratios that permit formation of stable low-organic content optical monoliths by UV-curing. The physical properties of the monoliths formed under different curing conditions were examined. The refractive-index increased with increased thermal-curing temperature and for combined thermal and UV-curing. On the other hand, the coefficient of thermal expansion (CTE) increases with the organic content for thermally-cured samples and decreases for UV-cured samples, due to full crosslinking. Additional important physical properties for sol-gel applications such as weight-loss, porosity and adhesive strength are also presented. The results obtained give guidelines for fabricating useful optical monoliths with lower CTE using a UV-curing process for applications such as optical bonding and encapsulation. © 2017 Elsevier B.V.

A 3-year comprehensive analysis of aflatoxin contamination in peanut butter was conducted in Zambia, sub-Saharan Africa. The study analyzed 954 containers of 24 local and imported peanut butter brands collected from shops in Chipata, Mambwe, Petauke, Katete, and Nyimba districts and also in Lusaka from 2012 to 2014. For analysis, a sample included six containers of a single brand, from the same processing batch number and the same shop. Each container was quantitatively analyzed for aflatoxin B1 (AFB1) in six replicates by using competitive enzyme-linked immunosorbent assay; thus, aflatoxin contamination level of a given sample was derived from an average of 36 test values. Results showed that 73% of the brands tested in 2012 were contaminated with AFB1 levels >20 g/kg and ranged up to 130 g/kg. In 2013, 80% of the brands were contaminated with AFB1 levels >20 g/kg and ranged up to 10,740 g/kg. Compared with brand data from 2012 and 2013, fewer brands in 2014, i.e., 53%, had aflatoxin B1 levels >20 g/kg and ranged up to 1,000 g/kg. Of the eight brands tested repeatedly across the 3-year period, none consistently averaged 20 g/kg. Our survey clearly demonstrates the regular occurrence of high levels of AF B1 in peanut butter in Zambia. Considering that some of the brands tested originated from neighboring countries such as Malawi, Zimbabwe, and South Africa, the current findings provide a sub-Saharan regional perspective regarding the safety of peanut butter.

This study assessed knowledge, attitude, and practices (KAP) of the public in Malawi on issues related to molds in foodstuffs. A survey involving structured questionnaire was conducted with 805 respondents from seven districts of Malawi. Descriptive statistics, t tests, and analyses of variance were calculated. A majority of respondents recognized that molds were dangerous to human health (88%); however, about 50% of respondents were not informed that mold toxins are thermally stable and that they are not destroyable by normal cooking processes. About 33% of the respondents asserted that they buy moldy maize, while approximately 20% of respondents reported that they consume moldy fruits having discarded moldy fraction. There were significant differences in knowledge scores among different demographic groups. Females had significantly (p<0.05) lower knowledge scores on issues related to molds in foods. Additionally, the respondents location had a significant effect. However, respondents education had subtle effect on knowledge score and the overall populations knowledge score was generally low (3.551.32 score out of 9). Results of the study underline the need to raise publics knowledge about health risks associated with spoilage molds in food and prevention and management options.

We have investigated the effect of organic content in hybrid organic/inorganic glasses prepared by the sol-gel process on the thermo-optic coefficient dn/dT. The organic phase consisted of homogeneously dispersed methyl groups within an inorganic silica matrix. Analysis of Fresnel reflectance temperature dependence of an optically polished sample-surface yielded the desired value, with an accuracy of 10 5/°C. A negative linear dependence of the thermo-optic coefficient on the volumetric thermal expansion coefficient β was obtained, dn/dT[10 4/°C] = -1.1-0.45β[10 4/°C]. Using Prod'homme's model, a negative value was derived for the electronic polarizability coefficient Φ = (-1.8 ± 0.3) × 10 4/°C. The negative sign of Φ is attributed to isolation of the silica matrix sections by the methyl groups, causing the sections to distance upon increase in temperature. © 2010 Elsevier B.V.

The saturated optical absorption of multi-walled carbon nanotube (MWNT)-doped hybrid-glass composites was studied at 1064 nm with nanosecond long pulses using the Z-scan technique. Increased transmission was demonstrated for high intensity pulses. The results were modeled for the limiting cases of a slow or a fast saturable absorber, both referring to a three-level system. The ground-state absorption cross section was estimated as 2.3x10-18 cm2, in good agreement with that of a single carbon atom. The excited state absorption cross section for carbon nanotubes (CNTs) was estimated for the first time as 6.9x10-19 cm3. The absorber's density of 2.8x1018 cm-3 is smaller by approximately a factor of 5 compared to the nominal density of carbon atoms incorporated into the glass. This could be a result of the broad band-like states formation in the MWNTs. The above figures were obtained by assuming that the excited state decay time was longer than the pulse duration of ~1 ns. © 2012 Optical Society of America.

Low frequency magnetic fields feature high penetration ability, whichallowscommunication, localization, and tracking in environments where radio or acoustic waves are blocked or distorted by multipath interferences. In the present work, we propose a method for tracking a magnetic receiver using beacons of low frequency magnetic field, where the receiver includes a tri-axial search-coil magnetometer. Measuring the beacons' magnetic fields and calculating the total-field signals enables localization without restrictions on magnetometer orientation, allowing on-the-move tracking. The total-field signals are used by a global search method, e.g., simulated annealing (SA) algorithm, to localize the receiver. The magnetic field produced by each beacon has a dipole structure and is governed by the beacon's position and magnetic moment. We have investigated two different methods for estimating beacons' magnetic moments prior to localization. The first method requires directional measurements, whereas for the second method the total-field signal is used.Effectiveness of these methods has been proved in numerous field tests. In the present work, we introduce a method for tracking a moving receiver by successive localizations. Using previous localization as a starting point of the search method for the next localization can reduce execution time and chances for divergence. The proposed method has been tested using numerous computer simulations. Successful system operation has been verified in field conditions. The good tracking capability together with simple implementation makes the proposed method attractive for real-time, low power field applications, such as mobile robots navigation. © 2014 IOP Publishing Ltd.

Stimulated Raman side scattering of an ultrashort high power laser pulse is studied in experiments on laser wakefield acceleration. Experiments and simulations reveal that stimulated Raman side scattering occurs at the beginning of the interaction, that it contributes to the evolution of the pulse prior to wakefield formation, and also that it affects the quality of electron beams generated. The relativistic shift of the plasma frequency is measured. © 2010 The American Physical Society.
