description: We investigate whether the baryon asymmetry of the universe is explained in the framework of the supersymmetric extension of the Standard Model with R-parity violating interactions. It is shown that the Affleck-Dine mechanism naturally works via a trilinear interaction $LLE^c$, $LQD^c$, or $U^cD^cD^c$, if the magnitude of the coupling corresponding to the operator $λ$, $λ'$, or $λ''$ is sufficiently small. The formation of Q-balls and their subsequent evolution are also discussed. The present baryon asymmetry can be explained in the parameter region where R-parity is mildly violated $10^{-9}\lesssimλ,λ',λ''\lesssim 10^{-6}$ and the mass of the gravitino is relatively heavy $m_{3/2}\gtrsim 10^4\mathrm{GeV}$. On the other hand, it is difficult to explain the present baryon asymmetry for larger values of R-parity violating couplings $λ,λ',λ''\gtrsim 10^{-5}$, since Q-balls are likely to be destructed in the thermal environment and the primordial baryon number is washed away.

description: Over the past two decades, an avalanche of data from multiwavelength imaging and spectroscopic surveys has revolutionized our view of galaxy formation and evolution. Here we review the range of complementary techniques and theoretical tools that allow astronomers to map the cosmic history of star formation, heavy element production, and reionization of the Universe from the cosmic "dark ages" to the present epoch. A consistent picture is emerging, whereby the star-formation rate density peaked approximately 3.5 Gyr after the Big Bang, at z~1.9, and declined exponentially at later times, with an e-folding timescale of 3.9 Gyr. Half of the stellar mass observed today was formed before a redshift z = 1.3. About 25% formed before the peak of the cosmic star-formation rate density, and another 25% formed after z = 0.7. Less than ~1% of today's stars formed during the epoch of reionization. Under the assumption of a universal initial mass function, the global stellar mass density inferred at any epoch matches reasonably well the time integral of all the preceding star-formation activity. The comoving rates of star formation and central black hole accretion follow a similar rise and fall, offering evidence for co-evolution of black holes and their host galaxies. The rise of the mean metallicity of the Universe to about 0.001 solar by z = 6, one Gyr after the Big Bang, appears to have been accompanied by the production of fewer than ten hydrogen Lyman-continuum photons per baryon, a rather tight budget for cosmological reionization.

Self-assembly of short chain Poly-N-isopropylacrylamid (PNIPAM) induced by superchaotropic Keggin Polyoxometalates: from globules to sheets

description: We show here for the first time that short chain poly(N-isopropylacrylamide) (PNIPAM), one of the most famous thermoresponsive polymers, self-assembles in water to form (i) discrete nanometer-globules and (ii) micrometric sheets with nm-thickness upon addition of the well-known Keggin-type polyoxometalate (POM) H3PW12O40 (PW). The type of self-assembly is controlled by PW concentration: at low PW concentrations, PW adsorbs on PNIPAM chains to form globules consisting of homogeneously distributed PWs in PNIPAM droplets of several nm in size. Upon further addition of PW, a phase transition from globules to micrometric sheets is observed for PNIPAMs above a polymer critical chain length, between 18 and 44 repeating units. The thickness of the sheets is controlled by the PNIPAM chain length, here from 44 to 88 repeating units. The PNIPAM sheets are electrostatically stabilized PWs accumulated on each side of the sheets. The shortest PNIPAM chain with 18 repeating units produces PNIPAM/PW globules with 5–20 nm size but no sheets. The PW/PNIPAM self-assembly arises from a solvent mediated mechanism associated with the partial dehydration of PW and of the PNIPAM, which is related to the general propensity of POMs to adsorb on neutral hydrated surfaces. This effect, known as superchaotropy, is further highlighted by the significant increase in the lower critical solubilization temperature (LCST) of PNIPAM observed upon the addition of PW in the mM range. The influence of the POM nature on the self-assembly of PNIPAM was also investigated by using H4SiW12O40 (SiW) and H3PMo12O40 (PMo), i.e. changing the POM’s charge density or polarizability in order to get deeper understanding on the role of electrostatics and polarizability in the PNIPAM self-assembly process. We show here that the superchaotropic behavior of POMs with PNIPAM polymers enables the formation and the shape control of supramolecular organic–inorganic hybrids.

The equation of optimal filtering, Kalman's filter and Theorem on normal correlation

description: An important objective of the classical processing of stationary random sequences under nonparametric uncertainty is the problem of filtering in case when the distribution of the underlying signal is unknown. In this paper it is assumed that an unknown useful signal $(S_n)_{n\ge1}$ is Markov. This allows us to construct an estimate of the useful signal, expressed in terms of the distribution density function of an observable random sequence $(X_n)_{n\ge1}$. The equation of the optimal Bayesian estimation (so called equation of optimal filtering) of such signal has been received by A.V. Dobrovidov. Our main result is the following. It is proved that when the unobservable Markov sequence is defined by a linear equation with the Gaussian noise, the equation of optimal filtering coincides with the classical Kalman's filter and the conditional expectation defined by the theorem on normal correlation.

description: A molecule with two or more atoms of the same element in distinct chemical environments is a trial system for probing site-specific fragmentation. In this context, special attention is deserved to 1,1,1,2-tetrafluoroethane (CF3CH2F), which has been the subject of numerous studies. This work discusses the effects of extreme ultraviolet (EUV) and soft X-ray irradiation on CF3CH2F from a dedicated translational kinetic energy release (KER) perspective. This analysis is achieved by evaluating the mean KER for its fragments at photon energies over 30–320 eV and computing the KER distribution (KERD) for the main fragments over the 282–320 eV range. The questions of interest from the point of view of the present study are twofold: (i) How do the mean KER of ionic fragments of the valence or core-excited CF3CH2F molecule change as a function of incident photon energy? (ii) Is there any evidence of site-specific or state-specific dissociation mechanisms in a molecule containing two carbon atoms in distinct chemical environments? From our results, lighter fragments showed to have their mean KER virtually following respective ion yields previously reported. And the overall learning is that the chemical environment associated with each C 1s excitation plays a role in differentiating the KER results.

description: In this article we investigate the excitations in a single graphene layer and in a single-walled carbon nanotube, i.e. the spectrum of magnetic excitations is calculated. In the absence of interactions in these systems there is a unique gap in the electron-hole continuum. We show that in the presence of Coulomb correlations new states, magnons, appear in this forbidden region. Coulomb interaction is examined in the context of Pariser-Parr-Pople (PPP) model which takes into account long range nature of interaction. The energy of new bound states depends on the strength of Coulomb forces. The calculations are performed for arbitrary electron-hole ($e-h$) momentum $\textbf{q}$ what allows to find the magnons dispersion law $\varepsilon(\textbf{q})$, effective mass $m^*$ and velocity $v_{gr}$. Finally, we determine the critical values of system parameters when this type of excitations can exist.

description: An exhaustive and theoretical analysis for the CH3SCH3 + HOO• and CH3CH2SCH3 + HOO• reactions has been examined using quantum chemistry theory. The potential energy surface was obtained by the CCSD(T)/CBS//M06-2X/cc-pVTZ level of theory. The overall rate coefficients have been calculated and the energetics and reaction enthalpies are also calculated. The calculated kinetics demonstrate that the hydrogen abstraction channels from the -CH3 group in CH3SCH3 and the -CH2 group in CH3CH2SCH3 are major channels in the low temperature region (less than 1000 K). However, the CH3-transfer channels forming CH3OOH become competitive reaction channels with the increase in temperature.
From the ground to space: an infrared view of active galactic nuclei

Publisher: name: Zenodo

description: In the past 10-15 years our view of the circumnuclear material of active galactic nuclei (AGN) has completely changed thanks to the combination of new observations and models. In particular, infrared and sub-mm high angular resolution observations from ground-based observatories have been crucial to peer into the innermost regions of AGN and study the geometry and composition of the nuclear obscurer, and how it is connected with the central engine (feeding) and the host galaxy (feedback). In this talk I summarize recent observational results in the infrared and sub-mm ranges showing that the circumnuclear material of AGN is complex and highly dynamic, varying with the periods of nuclear activity, AGN luminosity and Eddington ratio. I also discuss future prospects in the field based on the upcoming JWST data that will greatly contribute to our knowledge of the immediate surroundings of AGN.

description: The electronic, charge transport properties and UV-visible electronic transitions of a series of oxadiazole-based compounds 1–8 were calculated using DFT and TD-DFT methods. HOMO–LUMO gaps, reorganisation energies, and injection barriers were calculated at the B3LYP/6-31G(d,p) level of theory. The photophysical properties were predicted at the TD-PBE0/6-31G(d,p) computational level. The obtained results put in evidence that the designed oxadiazole derivatives 2–8 are better charge transport materials compared to the experimental derivative 1 and the reference materials Alq3 and TPD. The calculated reorganisation energies show that derivatives 6 and 4 are predicted as the best electron transport materials; whereas 4 and 5 are predicted as the best hole transport materials. The low values of the calculated ionisation and hole extraction potentials suggest that 4 is the best molecule for hole injection; whereas the high values of the calculated electron affinities and electron extraction potentials reveal that 6 is the most suitable derivative for electron injection. Absorption and fluorescence transitions involve mainly LUMOs and HOMOs. The designed fluorophore 8, which has the highest Stokes shift values, could be used in OLED light-emission layers.
Millisecond pulsar interpretation of the Galactic center gamma-ray excess

description: It was found in the Fermi-LAT data that there is an extended $γ$-ray excess in the Galactic center region. The proposed sources to be responsible for the excess include the dark matter annihilation or an astrophysical alternative from a population of millisecond pulsars (MSPs). Whether or not the MSP scenario can explain the data self-consistently has very important implications for the detection of particle dark matter, which is however, subject to debate in the literature. In this work we study the MSP scenario in detail, based on the detected properties of the MSPs by Fermi-LAT. We build a model of the Milky Way MSPs which can reproduce the $γ$-ray properties of the Fermi-LAT MSPs, and derive the intrinsic luminosity function of the MSPs. The model is then applied to a bulge population of MSPs. We find that the extended $γ$-ray excess can be well explained by the bulge MSPs without violating the detectable flux distribution of MSPs by Fermi-LAT. The spatial distribution of the bulge MSPs as implied by the distribution of low mass X-ray binaries follows a $r^{-2.4}$ profile, which is also consistent with the $γ$-ray excess data. We conclude that the MSP model can explain the Galactic center $γ$-ray excess self-consistently, satisfying all the current observational constraints.

description: We propose a number of variational regularisation methods for the estimation and decomposition of motion fields on the $2$-sphere. While motion estimation is based on the optical flow equation, the presented decomposition models are motivated by recent trends in image analysis. In particular we treat $u+v$ decomposition as well as hierarchical decomposition. Helmholtz decomposition of motion fields is obtained as a natural by-product of the chosen numerical method based on vector spherical harmonics. All models are tested on time-lapse microscopy data depicting fluorescently labelled endodermal cells of a zebrafish embryo.

description: We estimate polarizabilities of atoms in molecules without electron density, using a Voronoi tesselation approach instead of conventional density partitioning schemes. The resulting atomic dispersion coefficients are calculated, as well as many-body dispersion effects on intermolecular potential energies. We also estimate contributions from multipole electrostatics and compare them to dispersion. We assess the performance of the resulting intermolecular interaction model from dispersion and electrostatics for more than 1,300 neutral and charged, small organic molecular dimers. Applications to water clusters, the benzene crystal, the anti-cancer drug ellipticine---intercalated between two Watson-Crick DNA base pairs, as well as six macro-molecular host-guest complexes highlight the potential of this method and help to identify points of future improvement. The mean absolute error made by the combination of static electrostatics with many-body dispersion reduces at larger distances, while it plateaus for two-body dispersion, in conflict with the common assumption that the simple $1/R^6$ correction will yield proper dissociative tails. Overall, the method achieves an accuracy well within conventional molecular force fields while exhibiting a simple parametrization protocol.

description: Due to a single annual food production season in southern Africa, small-scale maize and sorghum farmers store grain until the next harvest. The farmers’ postharvest knowledge, perceptions and practices (KPP) is important in reducing postharvest losses (PHLs); a key component of household food and nutritional security. Using random sampling, 310 farmers from two districts of Zimbabwe with contrasting agroecologies and agricultural systems (maize and sorghum) were interviewed to assess their KPP on post-production aspects. Maize and sorghum grain were stored in new and recycled polypropylene bags (93.5% and 42.6%) placed in ordinary rooms (44.5% and 27.1%), brick store houses (28.4% and 54.2%) and traditional huts (23.2% and 16.1), respectively. Farmers recognised field infestation as important source of insect infestation in sorghum (60%) but not in maize (21.3%). Synthetic commercial grain protectants were used more on maize (90.2%) than on sorghum grain (63.2%). Majority of farmers (> 75%) perceived these insecticides as both effective and safe to use. Farmers’ household reserved grain ran out before the next harvest and was supplemented through buying grain or mealie-meal with cash, or exchanging grain with labour or livestock. Postharvest information and training were scarce in both systems. The study provides important information to extensionists, policy makers, development agents and researchers for reviewing and benchmarking extension services and farmer training requirements to effectively accelerate progress towards PHL reduction and contribute to household and national food and nutritional security.

description: Damals, wie heute spielen Metadaten eine Schlüsselrolle im wissenschaftlichen Publikationsprozess. Erst durch sie wird das jeweilige Werk, ob Textpublikation oder Forschungsdaten, sichtbar, nachvollziehbar und nachnutzbar. Die Digitalisierung der Wissenschaftskommunikation bietet die Möglichkeit Metadaten lokal oder verteilt zu erstellen, maschinell anzureichern und global über Schnittstellen auszutauschen. Vor allem Persistent Identifier (PIDs) als Rückgrat des wissenschaftlichen Publizierens sind auf Metadaten angewiesen, da erst durch sie das Versprechen des nachhaltigen Zugangs an die Zukunft eingelöst werden kann. Trotz der seit Jahren sich stetig verbessernden Möglichkeiten des Metadatenmanagements bleibt jedoch die Vollständigkeit von Metadaten weit hinter ihren Möglichkeiten zurück. Der Vortrag soll die Bedeutung von Metadaten wissenschaftlicher Publikationen und die Notwendigkeit der kollaborativen, gemeinschaftlichen Anstrengung ihrer Erstellung und Kuration beleuchten. Hierbei soll auf die Relevanz von Metadaten für PIDs im Allgemeinen und Digital Object Identifiern (DOIs) im Speziellen eingegangen werden. Zunächst soll die Struktur und der Status quo von DataCite-DOI-Metadaten anhand von Analysen des DataCite Metadatenschemas und der Nutzung der Metadatenfelder präsentiert werden. Um die zentrale Bedeutung von Metadaten zu illustrieren, werden die Workflows von der Erstellung, der Weiterleitung bis hin zur Verbreitung von DOIs exemplarisch dargestellt. Hierbei wird auf auf die bestehenden und zukünftigen Möglichkeiten der Metadatennutzung (PID-Graph, DataCite Commons), -optimierung und -komplettierung (Metadaten-Dashboards) eingegangen. Abschließend sollen Lösungsansätze und die Notwendigkeit der Kollaboration aufgezeigt werden. Dieser Vortrag versteht sich als Aufruf an alle Akteure der Wissenschaftskommunikation – von Forschenden selbst, über Informationsinfrastrukturen und Verlage hin zu offenen PID-Providern – zur gemeinschaftlichen Anstrengung der Verbesserung von Metadaten.

We give an elementary proof of the following known result: Two unimodular quadratic forms over $R$ are isometric over $K$ if and only if they are isometric over $R$. Our proof does not use Witt's Cancelation Theorem and yields an explicit algorithm to construct an isometry over $R$ from a given isometry over $K$. The statement actually holds for hermitian forms over valuated involutary division rings, provided mild assumptions. A python implementation of the algorithm derived from the proof can be found on the author's home page.

description: We study the fluctuations of certain random matrix products $Π_N=M_N\cdots M_2M_1$ of $\mathrm{SL}(2,\mathbb{R})$, describing localisation properties of the one-dimensional Dirac equation with random mass. In the continuum limit, i.e. when matrices $M_n$'s are close to the identity matrix, we obtain convenient integral representations for the variance $Γ_2=\lim_{N\to\infty}\mathrm{Var}(\ln||Π_N||)/N$. The case studied exhibits a saturation of the variance at low energy $\varepsilon$ along with a vanishing Lyapunov exponent $Γ_1=\lim_{N\to\infty}\ln||Π_N||/N$, leading to the behaviour $Γ_2/Γ_1\sim\ln(1/|\varepsilon|)\to\infty$ as $\varepsilon\to0$. Our continuum description sheds new light on the Kappus-Wegner (band center) anomaly.

title: Pharmaco-epidemiological study of cardiorespiratory safety of β2-agonists for the treatment and management of asthma, chronic obstructive pulmonary disease (DOPD) and asthma-COPD overlap
Creators: name: Amegadzie, Joseph Emil

description: Despite ample evidence underpinning the efficacy of β2-agonists in asthma and Chronic Obstructive Pulmonary Disease (COPD), the occurrence of β1-and β2- adrenoceptors in the heart suggests that β2-agonists may have deleterious cardiac effects. Therefore, patients who have asthma, COPD or both may be at increased risk of cardiorespiratory (CR) events because these diseases magnify the impact of these agents on the heart. In this thesis, I performed a systematic review and meta-analyses of the literature to provide a general overview of the comparative effectiveness and safety of inhaled medications. I conducted a retrospective cohort study to investigate gender differences in new-users of inhaled corticosteroids (ICS), short-or long-acting β2-agonist (SABA or LABA), ICS/LABA, short-or long-acting muscarinic antagonist (SAMA or LAMA) and a nested case-control study to test the association between β2-agonist-based medications and safety events for cardio-respiratory outcomes of major adverse cardiovascular events (MACE), all-cause mortality, and hospitalization for pneumonia using the United Kingdom Clinical Practice Research Datalink of patients with asthma, COPD or asthma- COPD overlap between 01-January-1998 and 31-July-2018. Results from the meta-analysis suggests that for patients with asthma–COPD overlap, LABA are associated with decreased risk of myocardial infarction in comparisons to non-LABA; and the combination therapy of ICS/LABA appears to reduce the risk of death or hospitalization in comparisons to placebo. Also, results from the gender-based analysis of pharmacotherapy use showed significant gender differences in new-users of inhaled pharmacotherapies among obstructive airways disease patients. In regards to the cardio-respiratory outcomes, new initiation of LABA, SABA or ICS/LABA compared to SAMA in COPD or SABA compared to ICS in asthma-COPD overlap was associated with an increased risk of MACE. However, among asthmatics, β2-agonists compared to ICS were not associated with risk of MACE. Consequently, starting LABA monotherapy or SABA monotherapy treatment was associated with an increased risk of all-cause mortality in patients with COPD. On the other hand, I observed no association with SABA, LABA or LABA/ICS in comparison with ICS or SAMA and the risk of pneumonia in patients with asthma, COPD or asthma-COPD overlap.

description: We derive the filtering equation for Markovian systems undergoing homodyne measurement in the situation where the output processes being monitored are squeezed. The filtering theory applies to case where the system is driven by Fock noise (that, quantum input processes in a coherent state) and where the output is mixed with a squeezed signal. It also applies to the case of a system driven by squeezed noise, but here there is a physical restriction to emission/absorption coupling only. For the special case of a cavity mode where the dynamics is linear, we are able to derive explicitly the filtered estimate $π_t (a)$ for the mode annihilator $a$ based on the homodyne quadrature observations up to time $t$.

description: Abstract:
Selection among alternative flood control measures would be better informed if better information could be obtained on the marginal change in flood hazard associated with land use and other changes in the tributary watershed. Hydrologic modeling is the most promising approach to answering this question; however, the use of existing models is hampered by the absence of information correlating model parameters with physical characteristics of the watershed.
To deal with this situation, a method was developed for estimating the parameter values for the Stanford Watershed Model which best match recorded with simulated streamflows. Physical characteristics were measured for 17 rural watersheds. Correlations between the characteristics and the parameters were examined. Changes in parameter values with urbanization were also examined. The results were used to study variations in downstream flood peaks and in average annual flood damages associated with various tributary watershed characteristics. The end product is better information on the kinds of areas where urban development is least likely to experience large flood damage and drainage costs.

description: This handbook describes the 12 thematic IT services developed and made
available for users as part of the Blue Cloud platform and tested in real
scenarios via the demonstrators, plus 2 additional generic IT services
available directly from the platform. Users are able to discover and
understand the services and then to re-run each of them as proposed by the
developers. To do this, they will need first to register as a Blue Cloud
user. This will allow them to access to the Blue Cloud Virtual Research
Environment (VRE) and the Virtual Laboratories (VLab) where the service
they look for is provided. This is true except for 1 Vlab for which
additional credentials provided by the scientists' developers are
requested. Points of contact are also given in case the users have
difficulties or questions regarding the service they want to try-out and
use. Some services give the possibility to the users to select other input
data or to "play" with several options. Services described are in a
prototype stage (TRL6 – 7) and may be enhanced following feedback from the
users. Therefore, please, as user, provide feedback to us! This handbook
will be corrected and updated during the year. It will be also improved
with additional services, thematic and generic, to provide the most
possible complete and up-to-date overview of the Blue Cloud services along
the project life.

description: The recent discovery of extragalactic PeV neutrinos opens a new window to the exploration of cosmic-ray accelerators. The observed PeV neutrino flux is close to the Waxman-Bahcall upper bound implying that gamma-ray bursts (GRBs) may be the source of ultra-high energy cosmic rays (UHECRs). Starting with the assumption of the GRB-UHECR connection, we show using both analytical estimates and numerical simulations that the observed neutrinos can originate at the jet as a result of photopion interactions with the following implications: the neutrino spectra are predicted to have a cutoff at energy $\le 10$ PeV; the dissipation responsible for the GRB emission and cosmic-ray acceleration takes place at distances $r_{\rm diss} \approx 3 \times 10^{11}-3 \times 10^{13} \ {\rm cm}$ from the central engine; the Thomson optical depth at the dissipation region is $τ_{\rm T} \sim 1$; the jet carries a substantial fraction of its energy in the form of Poynting flux at the dissipation region, and has a Lorentz factor $Γ\simeq 100-500$. The non-detection of $\sim$PeV neutrinos coincident with GRBs will indicate that GRBs are either poor cosmic accelerators or the dissipation takes place at small optical depths in the jet.

description: Maize needs to be stored using good and safe postharvest management measures that will maintain the quality as at harvest. Insects and moisture must be controlled in storage to ensure quality and methods to achieve this, such as the use of reduced-risk measures were evaluated in this study, conducted February–December 2016. The efficacy of Bularafa diatomaceous earth (DE), Piper guineense (Botanical), PICS bags, ZeroFly® bags and permethrin (Rambo™) in preserving maize quality in Nigerian markets was assessed. A sixth treatment comprised maize in untreated polypropylene bags. Study locations were in four markets in Ibadan, Ilorin and Oyo towns. Each market had a storehouse, which contained experimental 100-kg bags. In each storehouse, each technology had six bags, which were all sampled monthly except in PICS treatment where six bags were destructively sampled every four months. Data taken in February) and December) showed that quality of maize in PICS bags was best having the lowest percentage of insect damaged kernels, numerical based (%IDKNB), — 0.01 ± 0.01and 0.02 ± 0.01; %IDKWB— weight based were 0.00 ± 0.00 and 0.00 ± 0.00); % weight loss (0.01 ± 0.01; 0.01 ± 0.01), % number of discolored maize (0.02 ± 0.01; 0.01 ± 0.01) and % seed germination (96.77 ± 0.53; 98.37 ± 0.35) respectively. Treated and untreated maize had mean aflatoxin levels below limit of detection of 5 ppb in February and December (0.47 and 1.66), respectively and their proximate composition were within ranges reported in literature. By December, untreated maize had the highest %IDKNB (1.42 ± 0.22), %IDKWB (1.07 ± 0.18), % weight loss (0.36 ± 0.07) and lowest % seed germination (88.09 ± 0.98) when compared to the evaluated storage technologies Therefore, these five technologies can be incorporated in integrated management of storage insect pests in storehouses.

description: The severity of postharvest losses varies considerably depending on storage method and prevalence of storage insect pests known to bore into storage bags. Polypropylene (PP) bags used by smallholder farmers in Nigeria do not provide effective protection for stored produce due to insect boring activities. Deltamethrin incorporated polypropylene, ZeroFly® (ZF) and ZeroFly® Hermetic Storage Bags are technologies with potential to improve protection of stored food commodities against insect attack. Therefore, a 12-month study was conducted in Ibadan, Nigeria to determine the suitability and potential of combined postharvest bag technologies involving ZeroFly® (hermetic and non-hermetic) bags for smallholder farmers when exposed to Sitophilus zeamais and Prostephanus truncatus infestation pressure. Cleaned but un-fumigated 50-kg lots of maize were used to fill bags in each of the following 8 treatments — PP and ZF bags alone, diatomaceous earth-treated maize in PP and ZF bags, single and double hermetic liners in ZF bags, single hermetic liner in PP bags and lastly PICS bags. Results obtained over a 12-month period showed infestation by S. zeamais, Tribolium castaneum, Cryptolestes ferrugineus and Liposcelis spp. and abundance of insect increased with storage period in PP and ZF bags without liner. The percentages of insect damaged kernels by number (IDK) were higher in PP and ZF bags without liner and were 5.4 and 16.9%, respectively; in ZeroFly bags with hermetic liners, these values were ~ 0.5%. The PP and ZF bags without liner also had higher weight loss values of 1.4 and 6.7%, respectively compared with ZeroFly bags with hermetic liners and PICS bags which had a relatively lower weight loss of =0.2%. These results indicate that the ZeroFly Hermetic bag mitigates insect infestations, thereby offering a suitable alternative towards achieving significant reduction in postharvest losses during storage.
