Authors: Vega Angarita Olga Marina , González Escobar Dianne Sofía
Published: April 2020

Objetivo. Describir y determinar la relación entre el nivel de percepción de soporte social y la competencia para cuidar en el hogar de cuidadores familiares de personas adultas con enfermedad crónica. Método. Estudio correlacional con abordaje cuantitativo y de corte transversal realizado en una muestra de 103 cuidadores del municipio de Ocaña. Se utilizaron tres instrumentos: Ficha de caracterización Cuidador – persona con enfermedad crónica GCPC-UN-C, Soporte Social en enfermedad crónica de Hilbert (SSCI) y Competencia para el cuidado – Cuidador versión abreviada– GCPC-UN-CPC. Resultados. Respecto al soporte social se encontró satisfacción en todas las dimensiones de la escala de Hilbert y a nivel global. El nivel de competencia global para el cuidado en el hogar de los cuidadores fue adecuado; sin embargo se identifican necesidades de fortalecimiento en el conocimiento, lo instrumental y unicidad. Se identificó una correlación débil con baja significancia estadística entre las variables a estudio. Conclusiones. La competencia para cuidar en el hogar en el cuidador se desarrolla de manera independiente del nivel de satisfacción con el soporte social percibido.
Noise shaping in SAR ADC
Authors: Osipov Dmitry , Gusev Aleksandr , Shumikhin Vitaly , Paul Steffen
Published: April 2020

The successive approximation register (SAR) analog-to-digital converter (ADC)
is currently the most popular type of ADC architecture, owing to its power
efficiency. They are also used in multichannel systems, where power
efficiency is of high importance because of the large number of
simultaneously working channels. However, the SAR ADC architecture is not
the most area efficient. In SAR ADCs, the binary weighted capacitive
digital-to-analog converter (DAC) is used, which means that one additional
bit of resolution costs double the increase of area. Oversampling and noise
shaping are methods that allow an increase in resolution without an increase
of area. In this paper we present the new SAR ADC architectures with a noise
shaping. A first-order noise transfer function (NTF) with zero located
nearly at one can be achieved. We propose two modifications of the
architecture: with zero-only NTF and with the NTF with additional pole. The
additional pole theoretically increases the efficiency of noise shaping to
further 3 dB. The architectures were applied to the design of SAR ADCs in a
65 nm complementary metal-oxide semiconductor (CMOS) with OSR equal to 10. A
6-bit capacitive DAC was used. The proposed architectures provide nearly 4
additional bits in ENOB. The equalent input bandwitdth is equal to 200 kHz
with the sampling rate equal to 4 MS/s.
Accounting-Based Regulation: Evidence from Health Insurers and the Affordable Care Act
Authors: Eastman Evan M. , Eckles David L. , Van Buskirk Andrew
Published: April 2020

The Patient Protection and Affordable Care Act (ACA) requires that insurers spend a minimum amount of their premium revenue on policyholder benefits. The Act specifies enforcement via a combination of insurer self-reporting, government examinations, and payment of policyholder rebates in cases where insurers fail to meet the required spending amount. We find that insurers' reported estimates are consistently overstated in situations in which more accurate estimates would have triggered rebate payments; publicly traded insurers (particularly those exhibiting poor financial reporting quality) exhibit the strongest evidence of strategic over-estimating. In aggregate, we estimate that approximately 14 percent of insurers engage in strategic over-estimates, and that insurer over-estimates resulted in hundreds of millions of dollars in underpaid policyholder rebates. Our study illustrates how a combination of regulatory design choices and lax oversight can weaken the effectiveness of accounting-based regulation and have substantial economic consequences.

Published: April 2020

Chronic low-grade inflammation plays a central
role in the pathophysiology of gestational diabetes mellitus (GDM). In order to
investigate the ability of different inflammatory blood cell parameters in
predicting the development of GDM and pregnancy outcomes, 258 women with
GDM and 1154 women without were included in this retrospective study.
First-trimester neutrophil count outperformed white blood cell (WBC) count, and
neutrophil-to-lymphocyte ratio (NLR) in the predictability for GDM. Subjects
were grouped based on tertiles of neutrophil count during their first-trimester
pregnancy. The results showed that as the neutrophil count increased, there was
a step-wise increase in GDM incidence, as well as glucose and glycosylated
hemoglobin (HbA1c) level, Homeostasis Model Assessment for Insulin Resistance
(HOMA-IR), macrosomia incidence and newborn weight. Neutrophil count was
positively associated with pre-pregnancy Body Mass Index (BMI), HOMA-IR and
newborn weight. Additionally, neutrophil count was an independent risk factor
for the development of GDM, regardless of the history of GDM. Spline regression showed that there was a
significant linear association between GDM
incidence and continuous neutrophil count when it exceeded 5.0 × 109/L. This
work suggested that first-trimester neutrophil
count is closely associated with the development of GDM and adverse pregnancy outcomes.

Published: April 2020

Tutkimus perustuu Opetushallituksen ja Kansallisen koulutuksen arviointikeskuksen hankkeessa tuotettuun pitkittäisaineistoon, jossa samaan ikäluokkaan kuuluvien oppilaiden matematiikan osaamisen kehitystä on seurattu vuosien 2005–2015 aikana perusopetuksen kolmannelta vuosiluokalta toisen asteen koulutuksen loppuun. Tutkimus kohdistuu matematiikan parhaisiin osaajiin ja siihen, miten heidän osaamisensa on kehittynyt perusopetuksen aikana ja mikä erottaa parhaat osaajat muista. Tutkimusaineisto käsittää yhteensä 2051 oppilasta, jotka ovat osallistuneet kolmannella, kuudennella ja yhdeksännellä vuosiluokalla pidettyihin matematiikan osaamista kartoittaviin kokeisiin. Näistä yhdeksännen vuosiluokan kokeessa menestymisen perusteella parhaiden osaajien joukkoon luokiteltuja oppilaita on 256 (12,5 %). Tutkimustulosten mukaan suurin osa parhaista osaajista erottuu muusta tutkimusjoukosta jo kolmannella vuosiluokalla, ja ero muihin oppilaisiin näkyy selkeästi kuudennella luokalla. Oppilaan aikaisempi osaaminen, käsitys omasta osaamisesta ja vanhempien koulutustaso olivat selkeitä parempaa osaamista selittäviä tekijöitä. Tutkimuksessa havaittiin, että parhaiden osaajien tasolle voi yltää myös keskitasoa heikommasta lähtötasosta.

 

Evolving into a mathematically high-achieving student during basic education

Abstract

The study is based on the national evaluation of mathematics carried out by the Finnish National Agency for Education (EDUFI) and the Finnish Education Evaluation Centre (FINEEC). The development of mathematical competence of students of the same age group has been investigated during 2005–2012 from the third year of basic education to the ninth year. The study focuses on mathematically high-achieving students and how their skills have evolved during basic education and what kind of factors distinguish them from others. The longitudinal data consists of 2051 students who have taken part in mathematics examinations in the third, sixth and ninth grades. Definition of high-achieving students is based on success in the examination of ninth grade. Total number of high-achieving students is 256 (12,5 %). The results indicated that high-achieving students are distinguished from others in the third grade and the difference between them and other students is clearly visible in the sixth grade. Students’ previous mathematical performance, self-competence and the level of parents’ education were explanatory factors for better competence in ninth grade. The study found that the level of a high-achieving student can be attained also from a lower than average starting level.

Keywords: basic education, learning outcomes in mathematics, high-achieving students, longitudinal research, national evaluation in mathematics

Published: April 2020

ABSTRAKCommunity Service Activities (PPM) in Genteng Village, Sukasari Subdistrict, Sumedang Regency was initiated because the agrarian conflict had happened in that location. The conflict resolution were relatively slow due to the lack of understanding, knowledge and skills of the actors in conducting conflict resolution. In contrary, conflict resolution is clearly written inLaw Number 7 of 2012 about Managing of Social Conflict. In addition, the location of PPM also has a high potential for conflicts, especially conflicts in the useof natural resources. This must be anticipated by encouraging existing communities and local institutions to worktogether to prevent conflict and create a harmonious environment. The purpose of this PPM activity is to increase the knowledge, understanding and skills of target groups in conducting conflict resolution based on Law No. 7 of 2012 about Managing of Social Conflict, to increasethe knowledge, understanding and skills of target groups in conducting community-based conflict resolution and to encourage target groups to prevent conflicts andcan creat a harmony in the village. The target groups in this PPM activity are the farming community, village government and local institutions in the Genteng Village. The method of implementing PPM activities was conducted in several stages, such as the preparation phase, the assessment stage, the plan of treatment stage, and the activity implementation stage.
La poderosa diosa Maât

Published: April 2020

En este artículo se estudian las características fundamentales de la diosa Maât y su papel clave para mantener el equilibrio y el orden del cosmos. Se parte del examen de la “Maât de Florencia” por su perfección plástica y se presentan diversas facetas de la diosa, no tanto como idea abstracta ético-moral sino en un intento de resaltar su significado en el pensamiento egipcio, sus particularidades como divinidad en el panteón y sus relaciones con otros númenes. A continuación se analiza su presencia en la literatura egipcia como reflejo de esta sociedad, y, finalmente, su carácter femenino como símbolo de las mujeres egipcias. Se insiste en que su naturaleza femenina es la base de su posición central en la cosmovisión del Egipto antiguo, y encarna la importancia de la mujer en esa civilización antigua, que se puede considerar más uterina que fálica, a decir de los autores consultados.
La agenda institucional de las relaciones internacionales chinas. Análisis del documento oficial sobre la guerra comercial con Estados Unidos
Authors: Mosquera Mariano
Published: April 2020

¿Cuál es la agenda institucional de China en la guerra comercial con Estados Unidos? Esta investigación presenta, en un primer momento teórico, bases para el análisis institucional de China, y, en un segundo momento, un enfoque de agenda para interpretar la lógica institucional china en sus relaciones internacionales. En particular, se estudia la guerra comercial con Estados Unidos a partir del documento oficial del gobierno chino de septiembre de 2018. Con técnicas de reconocimiento de entidades y minería de textos, y con análisis de contenido, se obtienen dos tipos de resultados. Por una parte, el conflicto se caracteriza entre las categorías de la nueva economía institucional y se deconstruye por la retórica china con diversidad de fuentes de información que explicitan otros posibles contextos de actuación para las instituciones comerciales. Por otra parte, China presenta una resolución del conflicto en forma de agenda propositiva: se deben desarrollar procesos cooperativos económicos —no sólo comerciales— con enforcement político, para producir particularidad, dinamismo y coordinación a partir de las diferencias entre los dos países.

Published: April 2020

This paper examines the causality between fraud and bank performance in Nigeria over the period 2000-2016 for quarterly financial data using Johansen’s Multivariate Cointegration Model and Vector Autoregressive (VAR) Granger Causality analysis. The results show a long-run relationship between the variables. Bank performance was found to be linked to Granger fraud variables and vice versa at 10% significant level. This study reveals that there was a direct causal relationship between bank performance and fraud because increase in fraudulent activities in the banking sector leads to reduction in bank performance. Hence, this study recommends that internal control systems of banks should be strengthened so as to detect and prevent fraud. In this way, bank assets would be protected.
The Role of Main Microeconomic Factors on the Stock Prices of Selected Swiss Companies
Authors: Pražák Tomáš
Published: April 2020

This paper examines the role of main microeconomic factors on the stock prices of selected Swiss companies listed on the Six Swiss Exchange. Two basic theoretical approaches and interpretations of this relationship are frequently used. The efficient market hypothesis (Fama, 1970) assumes that stock prices already contain all the relevant information and the theory of arbitration (Ross, 1976, or Chen et al., 1986). The microeconomic factors are based on the financial situation in companies. Financial ratios, taken from the financial statements of the individual companies, are used for the analysis. In general, the study confirmed that profitability and debt ratios are the most important business factors from the prospective of impact on stock prices. The relationship between the observed variables is explored using panel regression analysis. The generalized method of moments for constructing a regression model is used. The sample period of the dataset is composed of annual data from 2006 to 2015.
Analysis of Chemical Composition Homogeneity in the Cross-section of the Rods Produced from Alloys of 6xxx Group
Authors: Vončina Maja , Cvahte Peter , Kračun Ana , Balaško Tilen , Medved Jožef
Published: April 2020

The alloys from Al–Mg–Si system provide an excellent combination of mechanical properties, heat treatment at extrusion temperature, good weldability, good corrosion resistance and formability. Owing to the high casting speed of rods or slabs, the solidification is rather non-equilibrium, resulting in defects in the material, such as crystalline segregations, the formation of low-melting eutectics, the unfavourable shape of intermetallic phases and the non-homogeneously distributed alloying elements in the cross-section of the rods or slabs and in the entire microstructure. The inhomogeneity of the chemical composition and the solid solution negatively affects the strength, the formability in the warm and the corrosion resistance, and can lead to the formation of undesired phases due to segregation in the material. In this experimental investigation, the cross-sections of the rods from two different alloys of the 6xxx group were investigated. From the cross-sections of the rods, samples for differential scanning calorimetry (DSC) at three different positions (edge, D/4 and middle) were taken to determine the influence of inhomogeneity on the course of DSC curve. Metallographic sample preparation was used for microstructure analysis, whereas the actual chemical composition was analysed using a scanning electron microscope (SEM) and an energy dispersion spectrometer (EDS).

Published: April 2020

Mathematics learning is directed at learning that can be done anytime and anywhere. Such learning can be done by conducting learning that is connected to the internet with the e-learning platform. For e-learning teacher use platforms can be used as learning media so that mathematical learning can be done anywhere. Researchers see that teachers especially teachers in junior high schools have difficulty in using e-learning in learning. This has an impact on students' understanding that is not optimal because teachers only rely on learning in the classroom. Service methods used are: 1) receiver theory and practice of e-learning 2) assignment of e-learning applications 3) evaluation of which e-learning has been applied inside outside the classroom. The results of this activity were that the trainees were seen to be motivated by 87% being received motivated, the remaining 13% were less motivated by the existence of this activity, then the response after the activity percentage that gave a positive response was 93% and 7% gave a less positive response. Another result is that most of the 15 teachers at SMPN 3 and 5 have used e-learning using either the google classroom or using moodle.
The Representation of the Film Director Andrei Tarkovsky’s Individual Artistic Worldview in the Short Story A White, White Day.
Authors: Berendeeva Maria S. , Borzenkova Natalia A.
Published: April 2020

The article deals with the description of the key elements of the conceptual space of the short story A White, White Day by Andrei Tarkovsky, which served as a basis in the key episode of the feature film Mirror. The aim of the research is to reveal and describe the main elements of the conceptual sphere of the short story. The object of research is the short story A White, White Day by Andrei Tarkovsky published in 1970 in the magazine Film Art in Movie Makers’ Stories section.
The main method used in the framework of the research is conceptual analysis of texts. To reveal the readers’ background notions about the short story and the author, to determine the semantics of the title and to reveal keywords on the basis of readers’ reception, we also used the experimental data obtained in 2017 when 51 students of Novosibirsk State University were surveyed. The participants were asked to read the information about the text and to answer 2 questions. The first one was asked before reading and was related to information known to the respondents – about the short story and its author and about their associations with the title. The second question (about the text keywords) was asked after reading. The results of the experiment were compared with the results of the analysis of the separate contexts of the short story and the possible intertextual connections, and the verbal representations of the revealed key concepts were compared with the intermedial representations of the key concepts of the feature film Mirror.
The following conclusions were made.
1. Even if readers do not know anything about the author of the text, its title and the epigraph create the particular semantic background on which the reception of the short story is superimposed: the notions about the loss of something good, about the mixture of positive and negative emotions, about the fact that the short story is based on the memories.
2. Through the title the individual concept of the white day is introduced into the conceptual space. This concept combines emotionally ambivalent notions about the supreme happiness lost forever, and it goes back to the poetry by Arseny Tarkovsky and Anna Akhmatova.
3. The frequently used lexemes and the short story keywords given to the respondents enable to reveal several key units of the conceptual space of the short story (the concepts of mother, water, childhood, war, wealth, grief, happiness, silence, home, church, fear, memory).
4. The key concepts of the short story are the conceptual basis of the subsequent film Mirror where the conceptual space gets more complicated and is supplemented by some new features.
Communication Failure in A. P. Chekhov’s Poetics: Architectonic Factor (A Nightmare, Enemies, An Awkward Business)
Authors: Sinyakova Lyudmila N.
Published: April 2020

Purpose. The article examines communication failure which is one of the major factor of Chekhov’s poetics. The problem of architectonics is based on dialogue principle in narrative and values unity.
Results. A Nightmare is a story of social misunderstanding. A public character Kunin treats a country priest father Yakov as a hard-drinking person. He is highly snobbish and refuses to hear the poor priest. Finally, his revelation of someone’s else being, except his own, shakes him much. But his newly gained knowledge about social issues such as destitution is not deep. Later, Kunin calms down and ruminates over his lack of money to help father Yakov and the other poor person, the doctor. The author’s conclusion discredits his attempt to become a better person. Overall, the dialogue of positions is just quasi-communication.
In his next work, Enemies, Chekhov’s poetic construction appears to be more complicated. Doctor Kirilov and Abogin, a rich man, both experience grief, but the reasons for their grief are entirely different. Doctor has lost his only little son an hour before, but Abogin compels him to save his wife. When they arrive to Abogin’s country-estate, it turns out that the woman has just run away with her lover. This farce provokes the doctor’s rage. He blames Abogin, saying that the rich man’s distress is empty and ridiculous. According to the author, the offended Kirilov can hardly be considered wrong. And once again, the author’s conclusion sums up the short story. An existential connotation manifests the communication breakdown.
The third short story, An Awkward Business, is devoted to problem of total communication failure. The main character, doctor Ovchinnikov, is not heard at all. His business matter turns out to be a matter of further existence, but nobody wants to understand the essence of his trouble. Finally, his case is interpreted in a formal way and is not solved. The author simply lets things go on, standing outside the text. And this is the innovative feature of Chekov’s mature creative work.
Conclusion. To sum up, in three Chekhov’s short stories communication failure is an important factor of poetics, which is developed in his later works.
Reduction of the Poetic Text in a Critical Essay by V. Nabokov Vladislav Khodasevich. Collected Verse.
Authors: Drozdova Anastasiia O.
Published: April 2020

The highlighting of Nabokov’s interpretational strategies in other literary texts is a relevant problem for Russian and European Nabokov studies. The goal of the article is to scrutinize the methods of reduction of a poetic text used by Nabokov in his early essay Vladislav Khodasevich. Collected Verse. The approach developed by receptive poetics allows author to describe Nabokov’s practices of reading and writing as an experience of creative game with literature of his contemporaries and predecessors. The narrative analysis is productive to characterize the point of view, to highlight the role of narrator in the structure of Nabokov's essay and his own literary work and the techniques for the transformation of Khodasevich’s poems into the prose. There are different methods of literary text reduction in Nabokov’s essay: creation of meta-plot not immanent in the original poems; selective sampling of literary contexts common for both authors; ignoring of artistic issue of ethics of beauty important for V. Khodasevich. For Nabokov, the reduction and transfer of his own techniques into the space of Khodasevich’s text is a way of approbation of patterns of artistic reality in texts of the poet, which conceptualizes the problem of boundaries of artistic talent, important for Nabokov himself.
Is the Rigidity of SARS-CoV-2 Spike Receptor-Binding Motif the Hallmark for Its Enhanced Infectivity? An Answer from All-Atoms Simulations

Published: April 2020

The latest outbreak of a new pathogenic coronavirus (SARS-CoV-2) is provoking a global health, economic and societal crisis. All-atom simulations enabled us to uncover the key molecular traits underlying the high affinity of SARS-CoV-2 spike glycoprotein towards its human receptor, providing a rationale to its high infectivity. Harnessing this knowledge can boost developing effective medical countermeasures to fight the current global pandemic.
An NADH-Inspired Redox Mediator Strategy to Promote Second-Sphere Electron and Proton Transfer for Cooperative Electrochemical CO2 Reduction Catalyzed by Iron Porphyrin
Authors: Smith Peter T. , Weng Sophia , Chang Christopher
Published: April 2020

We present a bioinspired strategy for enhancing electrochemical carbon dioxide reduction catalysis by cooperative use of base-metal molecular catalysts with intermolecular second-sphere redox mediators that facilitate both electron and proton transfer. Functional synthetic mimics of the biological redox cofactor NADH, which are electrochemically stable and are capable of mediating both electron and proton transfer, can enhance the activity of an iron porphyrin catalyst for electrochemical reduction of CO2 to CO, achieving a 13-fold rate improvement without altering the intrinsic high selectivity of this catalyst platform for CO2 versus proton reduction. Evaluation of a systematic series of NADH analogs and redox-inactive control additives with varying proton and electron reservoir properties reveals that both electron and proton transfer contribute to the observed catalytic enhancements. This work establishes that second-sphere dual control of electron and proton inventories is a viable design strategy for developing more effective electrocatalysts for CO2 reduction, providing a starting point for broader applications of this approach to other multi-electron, multi-proton transformations.

Bilayer graphene has attracted interest for its unique properties, including interesting electrical behavior when one layer is slightly rotated relative to the other. However, the quality of large-area bilayer graphene is often limited by the layer-plus-island growth mode in which islands of thicker graphene present as unavoidable impurities. Here, we report the observation of the layer-by-layer, Frank-van der Merwe (FM) growth mode in bilayer graphene where multilayer impurities are suppressed. Instead of the conventional surface adhesive energy, it is found that interface adhesive energy is possible to be tuned with an oxidative pretreatment. The FM-grown bilayer graphene is of AB-stacking or with small-twisting-angle (θ = 0-5°), which is more mechanically robust compared to monolayer graphene, facilitating a free-standing wet transfer technology.

A previous study shows that an ACE2 enzymatic activity inhibitor efficiently blocks the interaction of SARS-CoV spike protein with human ACE2 and may be effective in preventing the coronavirus membrane fusion and entry to human cells. The report suggests that potent ACE2 inhibitors can be used to treat hypertension as well as for controlling SARS-CoV infection. We here studied the effect of a selective and highly potent ACE2 inhibitor (MLN-4760) on the interaction of the SARS-CoV-2 spike receptor-binding domain (RBD) with human ACE2 by molecular dynamics (MD) simulation. To this end, we docked the RBD of SARS-CoV-2 to the human native ACE2 and the ACE2 complexed with MLN-4760, and analyzed the dynamics, protein-protein and ligand-protein interactions of the complexes by MD simulation in a simulated biological condition for 100 ns. Analyzing crystallographic structures of SARS-CoV-2 and SARS-CoV RBDs in the complexes with human ACE2 showed that RBD of SARS-CoV-2 binds to ACE2 with a higher affinity than that of SARS-CoV. Results also revealed that MLN-4760 binds to ACE2 at the enzymatic active site with a high affinity and significantly alters the ACE2 protein conformation. MLN-4760 also changes the binding site and the residues involved in hydrogen and hydrophobic binding between RBD and ACE2, however, it had no major effect on the binding affinity of the interaction between RDB and ACE2. Interestingly, binding RBD to the ACE2 complexed with MLN-4760 abrogated the inhibitory effect of MLN-4760 and rescued the conformation of the ACE2 enzymatic site by reforming the closed conformation to the open native conformation. This was due to the disassociation of MLN-4760 from the enzymatic active site of the ACE2 in the result of RBD binding. Overall, these results show that MLN-4760 does neither block nor increase the binding of SARS-CoV-2 spike RBD to human ACE2 and probably had no effect on the viral entry. However, binding the spike protein to ACE2 can rescue the enzymatic function of ACE2 from its inhibitor.

The foremost requirement for any catalyst to beimplemented in practice is its efficiency and stability. Thisrequirement is particularly valid for manganese hydrogenation catalysts representing more sustainable alternatives to conventional noble metal-based systems. Herein, we report a highly efficient Mn(I)-CNP pre-catalyst featuring phosphine arm hemilability, which gives rise to the excellent productivity (TOF° up to 41 000 h-1) and outstanding stability (TON up to 200 000) in hydrogenation catalysis. This system enables near-quantitative hydrogenation of ketones, imines, aldehydes, and esters at the catalyst loadings as low as 5-200 ppm. Our analysis points to the crucial role of the phosphine hemilability for the catalyst activation step and the stability of the reactive species under the catalytic conditions. Unprecedented inmanganese hydrogenation catalysis, this unusual coordination behavior might have general utility for improving catalysis by Mn complexes and bringing them yet another competitive advantage.

The study was carried out to investigate the microbiological quality of dried foods which
are very popular among kids. Moreover, people from all age groups like it, although adults
do not take it on a regular basis, the total consumed amount among the adults are not
negligible. Chips, biscuits, muesli, salted peanuts all are dried foods, and all of these can
undergo microbial contamination due to the remaining water activity, environmental
condition, production processing faults, humidity, temperature etc. In the current study,
twenty-four samples were analyzed for microbial quality analysis. Six samples from each
category of dried food were subjected to study for the presence of mesophilic organisms,
coliforms, molds and other specific food pathogens. Of the samples studied, almost all
were found to be contaminated with the mesophilic bacteria (104
-107CFU/g) and fungus
(105
-107CFU/g). Survival of Vibrio spp. was absent and Salmonella spp. was found in
only one sample. Escherichia coli, Pseudomonas spp., Staphylococcus spp. and Shigella
spp. were found in many of the samples indicating the poor quality of the dried food items.
Overall, the present study revealed that potato chips were highly contaminated by bacteria
and fungi. Consuming such contaminated chips may cause foodborne illness that is a great
threat to our health.
