description: We present a full analysis of a broadband spectral line survey of Sagittarius B2 (Main), one of the most chemically rich regions in the Galaxy located within the giant molecular cloud complex Sgr B2 in the Central Molecular Zone. Our goal is to derive the molecular abundances and temperatures of the high-mass star-forming region Sgr B2(M) and thus its physical and astrochemical conditions. Sgr B2(M) was observed using the Heterodyne Instrument for the Far-Infrared (HIFI) on board the Herschel Space Observatory in a spectral line survey from 480 to 1907 GHz at a spectral resolution of 1.1 MHz, which provides one of the largest spectral coverages ever obtained toward this high-mass star-forming region in the submillimeter with high spectral resolution and includes frequencies > 1 THz unobservable from the ground. We model the molecular emission from the submillimeter to the far-IR using the XCLASS program. For each molecule, a quantitative description was determined taking all emission and absorption features of that species across the entire spectral range into account. Additionally, we derive velocity resolved ortho / para ratios for those molecules for which ortho and para resolved molecular parameters are available. Finally, the temperature and velocity distributions are analyzed and the derived abundances are compared with those obtained for Sgr B2(N) from a similar HIFI survey. A total of 92 isotopologues were identified, arising from 49 different molecules, ranging from free ions to complex organic compounds and originating from a variety of environments from the cold envelope to hot and dense gas within the cores. Sulfur dioxide, methanol, and water are the dominant contributors. For the ortho / para ratios we find deviations from the high temperature values between 13 and 27 %. In total 14 % of all lines remain unidentified.

Technologies and data

description: No abstracts are to be cited without prior reference to the author.The bycatch of haddock (Melanogrammus aeglefinus) below legal size in the pelagic longline fisheries for haddock off the coast of Finnmark, northern Norway, is often high. This project was aimed at reducing the bycatch of undersized haddock through alterations in gear technology and fishing strategy. Fishing experiments with commercial longline vessels were carried out in June/July 1995 and 1996. The following modifications of fishing gear and fishing technology were tested: longlincs with increased sinking speed; hooks with an inedible plastic body attached to the shank; hooks with nylon bristles attached to the shank; restructured bait based on mackerel (Scomber scombrus) and sandeel (Ammodytes lancea); mackerel bait of twice the normal size; restructured mackerel bait of twice the normal size. None of the methods tested gave the desired improvements in the size distribution of the haddock catches. Traditional mackerel bait of twice the normal size about 40% reduction in undersized fish, but an increase in bait costs due to larger bait size, will not be accepted by commercial fishermen. In the survival experiments, where 18 haddock were tom off the longline hooks at the sea surface and kept in sea water tanks for five days, no mortality was found. One of the fishes was in bad condition at day five, and would probably not have survived if it was released to the sea. Additional experiments have to be carried out to confirm these results.

We then analyze algebraic structures of the Hochschild cohomology and describe the relation between deformations and solutions of the corresponding Maurer-Cartan equation. In Section 6 we generalize the Maurer-Cartan equation to strongly homotopy Lie algebras and prove the homotopy invariance of the moduli space of solutions of this equation. In the last section we indicate the main ideas of Kontsevich's proof of the existence of deformation quantization of Poisson manifolds.

description: Electrides are an emerging class of materials with excess electrons localized in interstices and acting as anionic interstitial quasi-atoms (ISQs). The spatial ion-electron separation means that electrides can be treated physically as ionic crystals, and this unusual behavior leads to extraordinary physical and chemical phenomena. Here, a completely different effect in electrides is predicted. By recognizing the long-range Coulomb interactions between matrix atoms and ISQs that are unique in electrides, a nonanalytic correction to the forces exerted on matrix atoms is proposed. This correction gives rise to an LA-TA splitting in the acoustic branch of lattice phonons near the zone center, similar to the well-known LO-TO splitting in the phonon spectra of ionic compounds. The factors that govern this splitting are investigated, with isotropic fcc-Li and anisotropic hP4-Na as the typical examples. It is found that not all electrides can induce a detectable splitting, and criteria are given for this type of splitting. The present prediction unveils the rich phenomena in electrides and could lead to unprecedented applications.

A study of anaerobic treatment of CTMP/TMP effluents
Creators: name: Vipat, Vasudha
Publisher: name: University of British Columbia

description: Prior to any extensive anaerobic treatment studies, it is essential to assess the impact of the components of the wastewater on the anaerobic microorganisms. Therefore, a simple, effective technique to assess the toxicity and degradability of various components of the wastewater is necessary. In this thesis, a technique is developed for measuring the biodegradability (Biochemical Methane Potential — BMP) and toxicity (Anaerobic Toxicity Assay — ATA) of the effluent components subjected to anaerobic treatment. The ATA measures the adverse effect of a compound on the rate of the total gas production from an easily-utilized methanogenic substrate (acetate and propionate). This method was used to determine the toxicity of sulphur compounds. Sulphate had no effect on anaerobic microorganisms, even at concentration of 1000 mg/L. Sulphide was found to be inhibitory above concentrations of 200 mg/L. Sulphite, on the other hand, was found to be extremely toxic even at a concentration of 100 mg/L. BMP is a measure of the substrate biodegradability determined by monitoring cumulative biogas production from a sample which is anaerobically incubated at constant temperature in a chemically defined medium. CTMP effluent was found to be more degradable and less toxic than TMP effluent. The degradability of CTMP effluent was maximum when it was diluted to between 50 and 25%, while that of the TMP effluent was maximum at 10% dilution.

description: Metal-Organic Frameworks (MOFs) have gained much interest due to their intrinsic tunable nature. In this work, we study how linker functionalization modifies the electronic structure of the host MOF, more specifically the MIL-47(V)-R (R=-F, -Cl, -Br, -OH, -CH$_3$, -CF$_3$, and -OCH$_3$). It is shown that the presence of a functional group leads to a splitting of the $π$-orbital on the linker. Moreover, the upward shift of the split-off $π$-band correlates well with the electron withdrawing/donating nature of the functional groups. For halide functional groups the presence of lone-pair back donation is corroborated by calculated Hirshfeld-I charges. In case of the ferromagnetic configuration of the host MIL-47(V$^{\mathrm{+IV}}$) material a half-metal to insulator transition is noted for the -Br, -OCH$_3$, and -OH functional groups, while for the anti-ferromagnetic configuration only the hydroxy-group results in an effective reduction of the band gap.

description: The main aim of the work presented here is to contribute to computer science advances in the multimodal usability area, in-as-much as it addresses one of the major issues relating to the generation of effective oral system messages: how to design messages which effectively help users to locate specific graphical objects in information visualisations? An experimental study was carried out to determine whether oral messages including coarse information on the locations of graphical objects on the current display may facilitate target detection tasks sufficiently for making it worth while to integrate such messages in GUIs. The display spatial layout varied in order to test the influence of visual presentation structure on the contribution of these messages to facilitating visual search on crowded displays. Finally, three levels of task difficulty were defined, based mainly on the target visual complexity and the number of distractors in the scene. The findings suggest that spatial information messages improve participants' visual search performances significantly; they are more appropriate to radial structures than to matrix, random and elleptic structures; and, they are particularly useful for performing difficult visual search tasks.

description: Ferroelectric materials are spontaneous symmetry breaking systems characterized by ordered electric polarizations. Similar to its ferromagnetic counterpart, a ferroelectric domain wall can be regarded as a soft interface separating two different ferroelectric domains. Here we show that two bound state excitations of electric polarization (polar wave), or the vibration and breathing modes, can be hosted and propagate within the ferroelectric domain wall. Specially, the vibration polar wave has zero frequency gap, thus is constricted deeply inside ferroelectric domain wall, and can propagate even in the presence of local pinnings. The ferroelectric domain wall waveguide as demonstrated here, offers new paradigm in developing ferroelectric information processing units.

Subjects: subject: General Relativity and Quantum Cosmology (gr-qc)

description: If a lot of dark matter particles accumulate near the black hole, then the chances of detecting dark matter signals near a black hole are greatly increased. These effects may be observed by the Event Horizon Telescope (EHT), Tianqin project, Taiji project, Laser Interferometer Space Antenna (LISA) and Laser Interferometer Gravitational-Wave Observatory (LIGO). In this work, we explore the effects of dark matter spikes on black hole space-time. For the Schwarzschild-like black hole case, we consider Newton$'$s approximation and perturbation approximation. This makes it possible to use Xu$'$s method to solve the Einstein field equation, and extend Schwarzschild-like black hole to Kerr-like black hole (BH) via Newman-Janis (NJ) algorithm. By analyzing the dark matter spike on the black hole event horizon (EH), stationary limit surfaces (SLS), ergosphere and energy-momentum tensors (EMT), we found that compared with the dark matter halo, the dark matter spike would have a higher effect on the black hole by several orders of magnitude. Therefore, if there is a dark matter spike near the black hole, it is very possible to test the dark matter model through gravitational wave (GW) observation and EHT observation.

description: The electroweak model is formulated on the nonlinearly realized gauge group SU(2) X U(1). This implies that in perturbation theory no Higgs field is present. The paper provides the effective action at the tree level, the Slavnov Taylor identity (necessary for the proof of unitarity), the local functional equation (used for the control of the amplitudes involving the Goldstone bosons) and the subtraction procedure (nonstandard, since the theory is not power-counting renormalizable). Particular attention is devoted to the number of independent parameters relevant for the vector mesons; in fact there is the possibility of introducing two mass parameters. With this choice the relation between the ratio of the intermediate vector meson masses and the Weinberg angle depends on an extra free parameter. We briefly outline a method for dealing with γ_5 in dimensional regularization. The model is formulated in the Landau gauge for sake of simplicity and conciseness: the QED Ward identity has a simple and intriguing form.

description: We provide an example of nonlocal scalar electrodynamics that allows the same Higgs mechanism so successful in local field theory. The nonlocal action is structured in order to have the same exact solutions and the same equations of motion for perturbations of the local theory, at any perturbative order. Therefore, the perturbative degrees of freedom that propagate in the unstable vacuum are reshuffled when the stable vacuum is replaced in the EoM, but their number does not change at any perturbative order, and their properties are the same like in the usual local theory. Finally, the theory is super-renormalizable or finite at quantum level.

description: No abstracts are to be cited without prior reference to the author.In order to evaluate the impact of Merluccius polli on the commercially exploited shrimps (P. longirostris and A. varidens), the seasonal consumption of these species by hake was estimated. A total of 1138 stomachs of fish over range of 10 to 59 cm and representing five age groups were examined. 28% of the stomachs collected were empty, with higher incidence in the size groups 20-29 and 30-39 cm. The relative importance and the total consumption in tonnes shows that this hake feeds mainly on fish, shrimps and cephalopods, with some preference for Myctophidae. The changes in prey species and its length size increase with increasing length of the predator and prey availability. The consumption of shrimps was higher than fish during summer (47.1%), and decreased to 32.2% during winter, related to the decrease in consumption of P. longirostris. The presence of his prey species in the stomachs sampled between 400-800 m during both seasons apparently justifies the vertical migration o: 􀃂3ke. 41.6 % of the variance was between individuals caught in the same haul.

description: Following a field-theoretical approach, we study the scalar Casimir effect upon a perfectly conducting cylindrical shell in the presence of spontaneous Lorentz symmetry breaking. The scalar field is modeled by a Lorentz-breaking extension of the theory for a real scalar quantum field in the bulk regions. The corresponding Green's functions satisfying Dirichlet boundary conditions on the cylindrical shell are derived explicitly. We express the Casimir pressure (i.e. the vacuum expectation value of the normal-normal component of the stress-energy tensor) as a suitable second-order differential operator acting on the corresponding Green's functions at coincident arguments. The divergences are regulated by making use of zeta function techniques, and our results are successfully compared with the Lorentz invariant case. Numerical calculations are carried out for the Casimir pressure as a function of the Lorentz-violating coefficient, and an approximate analytical expression for the force is presented as well. It turns out that the Casimir pressure strongly depends on the Lorentz-violating coefficient and it tends to diminish the force.

description: No abstracts are to be cited without prior reference to the author.Qualitative and quantitative composition of king crab food in the Barents Sea in spring, autumn and winter was determined. Echinodermata, molluscs and worms ( Polychaeta and Siohunculoidea) were found to be of first importance for king crab feeding. The diurnal rhythm of feeding was studied and rate of food digestion was estimated for large males of Varangerfjord. The dependence of rate of food digestion and oxygen consumption on the crab weight was found. Annual consumption of food by king crab population calculated using rate of food digestion and energy balance constituted 123-127% of body weight for males and 168-186% of that for females. Totally for the year, the population consumes nearly 5 thou. tonnes of benthos which constitutes no more than 1% of biomass consumed by fish-benthophages in the dwelling area of king crab in the Barents Sea. The preliminary estimation of the upper limit of king crab abundance in the new habitat area is given.

description: No abstracts are to be cited without prior reference to the author.Stock assessment of thorny skate, Raja radiata, for 1990- 1996 was made using data of trawl surveys for groundfish annually conducted by PINRO in the Barents Sea. The densest concentrations of the thorny skate were noted in central and coastal areas of the southern Barents Sea where mean catches constituted 14. 6 and 11. 8 specimens per 1-hour tow, respectively. In lesser amounts the thorny skate occurred in hwestern areas and Bear Island - Spitsbergen area (7.1 and 5.49 specimens per 1-hour tow). Total abundance of the thorny skate for the study period constitut:d from 30. 4 mill. specimens in 1992 to 108. 7 mill. specimens in 1994 and biomass was estimated from 34 .1 thou. tonnes in 1995 to 116.1 thou. tonnes 'in 1994. During 1994-1996, feeding and age variations in food composition of the thorny skate were studied. The thorny skate start to feed on northern shrimp from 20 cm length, when reaching 30 cm length, fingerlings and yearlings of cod as well as capelin, juvenile haddock and redfish appear in their food. Mean annual consumption of food constituted 152 thou. tonnes. In average for the year the thorny skate consume 14.2 thou. tonnes of juvenile cod at age 1-2, 11.2 thou. tonnes of northern shrimp, 2.8 thou. tonnes of capelin and 2.3 thou. tonnes of polar cod.

description: Silicon carbide, a refractory material, condenses near the photospheres of C-rich AGB stars, giving rise to a conspicuous emission feature at 11.3 mu. In the presence of a stellar wind, the SiC grains are carried outwards to colder regions, where less refractory carbonaceous material can condense, either by itself or in mantles upon SiC grains. Enough carbon can condense on the latter that their specific feature is completely veiled. Thus may be explained a) the coexistence of the SiC feature protruding above a carbonaceous continuum, with a range of contrasts, corresponding to various volume ratios of mantle to core; b) the ultimate disappearance of the 11.3-$μ$m feature from the interstellar medium, where the mantle has become completely opaque due to the much higher cosmic abundance of carbon.

Interannual variations of cod feeding were considered using average long-term published data from 1963 to 1990 and original data for 199.2''. 1997. Diurnal rythmics of cod feeding was revealed. The analysis of cod food relations was carried out at various stages of ontogenesis. A single instantaneous food consumption (SIC) by cod amounted to 246.t in 1995; .283 tin 1996 and 142 tin 1997. In spring 1996 cod consumed 60 thous. t of food. About 70% of food consisted of sprat and Baltic herring.

description: We calculate the vector and axial-vector form factors of $B_{u,d,s}$ decays into P-wave axial-vector mesons in the light-cone sum rule approach. For the sum rule results, we have included corrections of order $m_A/m_b$, where $m_A$ is the mass of the axial-vector meson $A$. The results are relevant to the light-cone distribution amplitudes of the axial-vector mesons. It is important to note that, owing to the $G$-parity, the chiral-even two-parton light-cone distribution amplitudes of the $^3P_1$ ($^1P_1$) mesons are symmetric (antisymmetric) under the exchange of quark and anti-quark momentum fractions in the SU(3) limit. For chiral-odd light-cone distribution amplitudes, it is the other way around. The predictions for decay rates of $B_{u,d,s} \to A e ν_e$ are also presented.

description: Graham Wood was a world-leading corrosion scientist who bridged both the aqueous (electrochemical) corrosion and high-temperature oxidation branches of the subject. His analytical predictions of depletion and enrichment profiles in substrate and scale during preferential oxidation have long been confirmed in practice. He also demonstrated that transient oxides can be vital solid lubricants in oxidative friction and wear processes. He elucidated ionic transport in amorphous anodic films, leading to precise models of pore initiation, development and closure, thus allowing the strict design of anodic films for practical application.

description: We consider finite element discretizations of Maxwell's equations coupled with a non-local hydrodynamic Drude model that accurately accounts for electron motions in metallic nanostructures. Specifically, we focus on a posteriori error estimation and mesh adaptivity, which is of particular interest since the electromagnetic field usually exhibits strongly localized features near the interface between metals and their surrounding media. We propose a novel residual-based error estimator that is shown to be reliable and efficient. We also present a set of numerical examples where the estimator drives a mesh adaptive process. These examples highlight the quality of the proposed estimator, and the potential computational savings offered by mesh adaptivity.

description: Barangay tanods are not exempted from the risk of the COVID-19 due to being exposed to public areas. Aside from health risks, these front liners are also a mistreatment subject from violators. Thus, this study is conducted during the pandemic and gathered data through a phone interview. It is conducted to explore the lived experiences of Barangay Tanods and how they adjusted to the drastic change in the work environment, health risk exposure to COVID-19, and the threat of danger caused by different factors during community quarantine. It also determines the specific challenges in the work environment and the changes in policing strategies, and how they cope. Lastly, it aims to map out how these experiences and impacts will improve preparations and the development of policing strategies in future crises. Moreover, three major conclusions emerge from this study's findings: (1) Barangay tanods faced difficulties in the sudden shift of their work environment (2) Most of the barangay tanods received incentives from the government to supply their health and sanitary needs (3) Barangay tanods reflected on their experiences to further improve as public servants and to be prepared for future crisis.
Thermodynamic properties from cubic equations of state

description: The Lielmezs-Merriman equation of state has been modified in such a way that it can be applied over the entire PVT surface except along the critical isotherm. The dimensionless T* coordinate has been defined according to the two regions on the PVT surface as: [Formula Omitted] The two substance-dependent constants p and q are generated from the vapor pressure data. The applicability of the proposed modification has been tested by comparing its predictions of various pure compound physical and thermodynamic properties with known experimental data and with predictions from the Soave-Redlich-Kwong and Peng-Robinson equations of state. The proposed equation is the most accurate equation of state for calculating vapor pressure, and saturated vapor and liquid volumes. The Peng-Robinson equation is the best for enthalpy and entropy of vaporization estimations. The Soave-Redlich-Kwong equation is the least accurate equation for pressure and volume predictions in the single phase regions. For temperature prediction, all three equations of state give similar results in the subcritical and supercritical regions. None of the three equations is capable of representing all departure functions accurately. The Peng-Robinson equation and the proposed equation are very similar in accuracy except in the region where the temperature is near the critical. That is, between 0.95 ≤ Tr ≤ 1.05, the proposed equation gives rather poor results. For isobaric heat capacity calculation, both Soave-Redlich-Kwong and Peng-Robinson equations are adequate. The Soave-Redlich-Kwong equation gives the lowest overall average RMS % error for Joule-Thomson coefficient estimation. The Soave-Redlich-Kwong equation also provides the most reliable prediction for the Joule-Thomson inversion curve right up to the maximum inversion pressure. None of the cubic equations of state studied in this work is recommended for second virial coefficient calculation below Tr = 0.8. An α-function specifically designed for the calculation of second virial coefficient has been included in this work. The estimation from the proposed function gives equal, if not better, accuracy than the Tsonopoulos correlation.

description: Ground state energies for confined hydrogen (H) and helium (He) atoms, inside a penetrable/impenetrable compartment have been calculated using Diffusion Monte Carlo (DMC) method. Specifically, we have investigated spherical and ellipsoidal encompassing compartments of a few nanometer size. The potential is held fixed at a constant value on the surface of the compartment and beyond. The dependence of ground state energy on the geometrical characteristics of the compartment as well as the potential value on its surface has been thoroughly explored. In addition, we have investigated the cases where the nucleus location is off the geometrical centre of the compartment.

description: In its intrinsic ambivalence, the web presents two ‘sides’: the one that creates opportunities and the one that poses risks. Within the context of the processes of construction and transmission of news, there is a variety of phenomena related to the so-called "information disorders" (Wardle Derakhshan, 2017). Fake news (the most widespread forms of disinformation) represents an insidious form of "post-truth rhetoric" (McComiskey, 2017) and stimulates the brain to detect its risks, which range from the weakening of readers confidence in information sources to the difficulty in distinguishing the true from the false (Shu et al., 2020). Within this context, a key role is played by images. Starting from these premises, this paper aims to deepen, in the context of social psychology and communication, thus going beyond the purely linguistic aspect, how the 'visual' part of news can contribute to the distortion of both the information provided and the main subject, in this case migrants. Therefore, this paper analyzes 99 false reports on immigration in order to understand the role played by images and to detect whether a stereotypical representation of immigration is present. Nella sua intrinseca ambivalenza, il web opera presentando molteplici facce, riconducibili ai due estremi del creare opportunità e generare rischi. Proprio nell’ambito dei processi di costruzione e trasmissione delle notizie, si riscontra una varietà di fenomeni afferenti ai cosiddetti “disturbi informativi” (Wardle Derakhshan, 2017). Considerate tra le forme di disinformazione più diffuse, le fake news rappresentano forme insidiose di “post-truth rhetoric” (McComiskey, 2017), stimolando la ricerca psicosociale a rilevare i rischi legati alla fruizione delle stesse, che vanno dalla erosione della fiducia dei lettori nei confronti del mondo delle informazioni agli ostacoli rispetto alla loro abilità di differenziare ciò che è vero da ciò che è falso (Shu et al., 2020). Tra le molteplici modalità attraverso cui una fake news viene “confezionata”, un ruolo particolare è svolto dalle immagini. Partendo da tali premesse, il presente contributo si propone di approfondire, nell’ambito della psicologia sociale e della comunicazione, oltre l’aspetto meramente linguistico, in che modo la parte il ‘visual’ delle notizie può contribuire alla distorsione della notizia e del target descritto, rappresentato in questo caso dai migranti. A questo scopo sono state raccolte 99 notizie false riguardanti il tema dell’immigrazione e analizzate al fine di comprendere il ruolo svolto dalle immagini, ma soprattutto se questo è in qualche misura collegabile ad una visione stereotipica dell’immigrazione.

description: In this note we revisit the subject of anomaly cancelation in string theory and M-theory on manifolds with String structure and give three observations. First, that on String manifolds there is no E8 x E8 global anomaly in heterotic string theory. Second, that the description of the anomaly in the phase of the M-theory partition function of Diaconescu-Moore-Witten extends from the Spin case to the String case. Third, that the cubic refinement law of Diaconescu-Freed-Moore for the phase of the M-theory partition function extends to String manifolds. The analysis relies on extending from invariants which depend on the Spin structure to invariants which instead depend on the String structure. Along the way, the one-loop term is refined via the Witten genus.

description: The Gould Belt (GB) is a system of gas and young, bright stars distributed along a plane that is inclined with respect to the main plane of the Milky Way. Observational evidence suggests that the GB is our closest star formation complex, but its true nature and origin remain rather controversial. In this work we analyze the fractal structure of the stellar component of the GB. In order to do this, we tailor and apply an algorithm that estimates the fractal dimension in a precise and accurate way, avoiding both boundary and small data set problems. We find that early OB stars (of spectral types earlier than B4) in the GB have a fractal dimension very similar to that of the gas clouds in our Galaxy. On the contrary, stars in the GB of later spectral types show a larger fractal dimension, similar to that found for OB stars of both age groups in the local Galactic disk (LGD). This result seems to indicate that while the younger OB stars in the GB preserve the memory of the spatial structure of the cloud where they were born, older stars are distributed following a similar morphology as that found for the LGD stars. The possible causes for these differences are discussed.

description: Kinetic approaches provide an effective description of the process of particle acceleration at shock fronts and allow to take into account the dynamical reaction of the accelerated particles as well as the amplification of the turbulent magnetic field as due to streaming instability. The latter does in turn affect the maximum achievable momentum and thereby the acceleration process itself, in a chain of causality which is typical of non-linear systems. Here we provide a technical description of two of these kinetic approaches and show that they basically lead to the same conclusions. In particular we discuss the effects of shock modification on the spectral shape of the accelerated particles, on the maximum momentum, on the thermodynamic properties of the background fluid and on the escaping and advected fluxes of accelerated particles.

description: No abstracts are to be cited without prior reference to the author.In this work, we study the genetic composition and its relationship with some fitness parameters in a group of juvenile Atlantic salmon. We analyze the fork length, the weight and age of the first active feeding parameters than can conditioned the election of different options within the life cycle of Atlantic salmon in its first stages in freshwater. Atlantic salmon juveniles were obtained of a 20 males x 20 females cross frorri MSW adults returning to the River Shin (Scotland). Fish were divided into early and late first. feeding group. Both classes of fish were reared together and at regular intervals their fork length and wet mass measured. At the end of experiment the fish were killed and individual· genetic variability determined for six loci, MDH-3,4* mMEP-2* sAAT-4* /DHP-3*, IDDH-1* and IDDH-2*. The only significant difference in allelic frequency for an individual locus between early and late first feeding groups was recorded for the mMEP-2* locus. However, differences in the pattern of overall genetic variability were observed, suggesting a relationship between the level of heterozygosity and timing of first feeding. Individuals homozygous for mMEP-2*100 allele, and heterozygous at AAT-4*Iocus, showed significant higher values of weight and length than other genotypes that may indicate an association between selection of these loci and performance.
