Authors: Escobar-Vidarte María Fernanda , Loaiza-Osorio Sara Del Pilar , Nieto-Calvache Albaro José
Published: October 2018

Objetivo: realizar una revisión de la literatura publicada sobre el tratamiento de la trombosis de vena cava inferior en las gestantes.Materiales y métodos: se describe un caso de trombosis de vena cava inferior en embarazo a término que consultó a una institución privada de cuarto nivel de complejidad, centro de referencia. Se manejó inicialmente con heparina de bajo peso molecular, suspendida 24 horas antes del parto. Se obtuvo un buen resultado perinatal, aunque presentó hemorragia postparto y hematoma perineal. Posteriormente se hizo manejo endovascular para trombolisis e intento de trombectomía. Se realizó una revisión de la literatura con los términos “vena cava inferior”, “filtros de vena cava”, “trombosis” y “embarazo”. Se incluyeron reportes de caso y series de casos en inglés y español. Se seleccionaron todos los casos que describieran el tratamiento utilizado en mujeres con trombosis de vena cava inferior, diagnosticadas durante el embarazo o el puerperio.Resultados: se incluyeron 17 publicaciones que cumplieron con los criterios de búsqueda. Se identificaron 41 casos; 35 pacientes fueron diagnosticadas con trombosis de vena cava inferior durante el embarazo y 6 durante el puerperio. El 100 % de las pacientes fueron anticoaguladas con heparina de bajo peso molecular o heparina no fraccionada, 34 gestantes requirieron filtro de vena cava inferior para manejo periparto y solo una gestante terminó en trombectomía.Conclusión: la trombosis de vena cava inferior en el periparto es un reto desde el punto de vista terapéutico, se debe equilibrar el riesgo de TEP y hemorragia masiva. Es fundamental tener una adecuada coordinación entre los diferentes servicios implicados garantizando máxima seguridad para evitar complicaciones.

MPPT Algorithm Based on PV Cell Temperature, Using Open Circuit Voltage Measurement, Combined With PV Cell Cooling
Authors: Rocha Nuno M. M. da , Brighenti Lucas L. , Passos Júlio César , Martins Denizar C.
Published: October 2018

As an increase of Photovoltaic (PV) cell temperature originates a negative effect, the application of a PV cell cooling system allows a performance improvement. Therefore, the present work aims to investigate the performance of a PV module transformed into a Photovoltaic/Thermal (PV/T) module, producing electrical and thermal energy simultaneously, while concurrently establishing a cooling system for the PV cells. The PV conversion efficiency is affected by modifications of the operation conditions particularly the ones concerning PV cell temperature and radiation due to the displacement of the system Maximum Power Point (MPP). In the present work the Maximum Power Point Tracking (MPPT) is performed using an algorithm based exclusively on PV cell temperature information with the particularity that the temperature measurements are perform without the use of any temperature sensors. The studied system performance is compared to a conventional PV using the same MPPT algorithm. The results show that the cooling system associated to the MPPT temperature based algorithm provides a bigger energy output leading to higher economic savings. In addition, it can help simplifying the MPPT algorithm by allowing the use of slower dynamic.
Polski Związek Sportowy jako organizacja w teorii pól Fligsteina i McAdama
Authors: Mańkowski Dobrosław
Published: October 2018

W polskiej socjologii nie prowadzono badań dotyczących takiej organizacji jak Polski Związek Sportowy. W niniejszym artykule staram się wskazać istotne elementy z zakresu teorii i metodologii socjologii organizacji, które można stosować do badania związku sportowego. Korzystając głównie z teorii pól Fligsteina i McAdama (2016), wskazuję, po pierwsze, na usytuowanie Polskiego Związku Sportowego w polu instytucjonalno-prawnym. Po drugie, odnoszę się do struktury wewnętrznej związku, istniejącego w nim subpola władzy, a także pokazuję szereg innych istotnych zależności istniejących w związku sportowym, takich jak działanie „czynnika ludzkiego” w kreowaniu, zarządzaniu i trwaniu tego związku. Po trzecie, opisuję usytuowanie związku sportowego na mapie instytucjonalnej na mezopoziomie jego działania.
„Ten żył zdrowo, a ten żył choro”. O rozumieniu zdrowia i ruchu przez dzieci
Authors: Maciejewska-Mroczek Ewa
Published: October 2018

Opracowanie to przedstawia wyniki badań prowadzonych wśród dzieci w wieku 8–11 lat, dotyczących tego, jak rozumieją one różne aspekty zdrowia czy zdrowego stylu życia. Wśród najistotniejszych komponentów dbania o zdrowie dzieci wymieniały ruch. W zebranym materiale istotne jest przypisywanie przez rozmówców wartości moralnych tym aktywnościom. Człowiek, który „biega, jeździ na rowerze, pływa”, jest kimś nie tylko zdrowym, ale i moralnym. Przeciwieństwem zaś takiej postawy jest nie tylko niezdrowy tryb życia, lecz także niski poziom moralny (np. uleganie nałogom) oraz wzmacniająca ten nieprzychylny obraz odpychająca fizyczność. W narracjach dzieci określenia „zdrowe” i „dobre” traktowane były często wymiennie. Dzieci traktują ruch nie tylko jako obszar „dobry”, czyli zdrowy, lecz także – przynoszący satysfakcję. W opinii uczestników badań, dla sportu i ruchu jest miejsce w różnych, nie zawsze kojarzonych z nimi przestrzeniach, a ich praktykowanie jest spójne z ich wizją tego, co to znaczy być dzieckiem.
Apollińskość i dionizyjskość jako kategorie doświadczenia sportowego. Interpretacja pisemnych relacji z ultramaratonów w świetle teorii Ruth Benedict
Authors: Kosznicki Adam
Published: October 2018

Artykuł ten poświęcony jest interpretacji tekstów z blogów o ultramaratonach, czyli biegach na dystansie dłuższym niż standardowy maraton (42,195 km). Ta subdyscyplina biegania długodystansowego obecnie prężnie się rozwija i stale przyciąga nowych uczestników, czemu towa­rzyszy między innymi szybko postępujący rozwój blogosfery poświęconej tej tematyce. Internetowe dzienniki biegaczy nie były jednak do tej pory analizowane zbyt obszernie przez badaczy społecznych. Dlatego w tym tekście autor podjął próbę wypełnienia tej luki empirycznej, zaś treść badanych blogów ma posłużyć do zrozumienia głębszego sensu praktyki, jaką jest uczestnictwo w ultramara­tonach. Podstawą teoretyczną tej pracy są rozważania Ruth Benedict i stosowane przez nią pojęcia apollińskości oraz dionizyjskości. Pojęcia te wspomniana autorka zapożyczyła od F. Nietzschego i stosowała w opisie kultury Indian Ameryki Północnej. Głównym celem badawczym, który postawił sobie autor prezentowanego tekstu, jest próba analizy form przejawiania się apollińskości i dio­nizyjskości w pisemnych relacjach z ultramaratonów. Do analizy zebranych materiałów posłużyła metoda analizy dokumentów osobistych, a interpretacji poddane zostały treści tekstowe zamiesz­czone na blogach. W podsumowaniu znajdują się wnioski płynące z całości rozważań oraz sugestie co do dalszych badań socjologicznych.

IMPROVING TRANSPARENCY AND ACCOUNTABILITY OF MSME FINANCIAL STATEMENTS BY USING ACCRUAL METHOD
Authors: Risnaningsih Risnaningsih , Tanuwijaya Sjheny , Iriani Nur Ida
Published: October 2018

Many Micro, Small, and Medium Enterprises (MSMEs) are still carrying out a simple accounting record and have not implemented accrual basis method. It is expected that in the future all MSMEs can make more transparency and accountability report by using accrual method so it can assist MSMEs in applying credit to banks or other investors to increase the business capital. This study was conducted in Malang Regency, Batu City, and Malang City. This study used descriptive qualitative method. The data collection techniques were done by interview and documentation with sampling technique using purposive sampling and snowball sampling. The collected data will be analyzed by interactive analysis method including data reduction, data presentation, and data verification or interpretation. The results showed that the owners of SMEs in managing their finances use simple accounting by using accrual method so that the financial statements produced more accurate than if the owners of MSMEs use cash method. The owners of SMEs do not need to make complete financial statements, they may use three types of financial statements, namely: income statement, balance sheet, and cash flow statement. The income statement is used to find out how much the profit or loss of the MSMEs, the balance sheet is used to find out the assets, liabilities, equity, and cash flow statement is used to find out the changes occurring during the period of operating, investing, and financing activities. These three types of financial statements have already been used by MSME owners as one of the requirements to obtain credit from banks or other investors.

The magic of an Allaisian appraisal: implied and historical volatility revisited the VIX: once bitten, twice shy?
Authors: MUNIER Bertrand , BARTHALON Eric , MENGUY Séverine
Published: October 2018

Many contributions have dealt with the relation between implied and historical volatility in reference to the S&P100 index and on mostly limited samples of data. A large part of this literature finds that implied volatility defined directly from option prices is a biased estimator of future realized volatility, although some dissent has been expressed Christensen and Prabhala (1998). We investigate the issue on the larger market of the S&P500, using the VIX index as the measure of implied volatility and on a much larger sample (314 months), extending from January 1990 to December 2016. Our results are in line with most of the literature inasmuch as they invalidate the efficient market hypothesis. More originally, however, we use a time series analysis derived from Maurice Allais’s “lost” work on monetary theory and show that the VIX incorporates a subtle version of perceived and memorized past data – the “missing link” in relating implied to realized volatility - rather than reflecting any kind of “rational expectation” of future realized volatility. Incidentally, we show that the VIX seems to have been over-valued until the middle of the first decade of our century and to be since then averagely under-valued. Amazingly enough, this trend of affairs seems to be steadily confirmed by the financial market, which calls for additional research, even if we offer two possible explanations.
Non Linear Strain Measures on Concrete Structures by Means of Embedded Optical Fiber Sensors
Authors: Minutolo Vincenzo , Zona Renato
Published: October 2018

Optical fiber sensors have become a widely-used tool to perform life-long monitoring of large structures. Different set-ups of sensors can be used to obtain information at different scopes. In this paper, the application of a portable Brillouin optical time domain analysis sensor applied to reinforced concrete beams is presented. The sensor is made up of a single-mode optical fiber applied to the structure that enables the measurement of tensile and compressive axial strain along the beams. The fiber is embedded into a concrete casting and fixed along the reinforcement bars so that a complete correlation can be obtained regarding strain and displacements in linear and non-linear flexural response. The use of four sensing fibers positioned along the beam's length at different vertical positions makes it possible to read the strain variation within the cross-section. In accordance with Bernoulli’s hypothesis, this allows curvature diagrams to be obtained across the structure. The measured curvature is used to set up the moment–curvature relationship, which highlights the possibility of the sensor monitoring structures continuously in space and time.
Neurologic and Inflammatory Manifestations in Sjögren’s Syndrome: The Role of Tryptophan/kynurenine Pathway
Authors: Oliveira Fabiola Reis , Fantucci Marina Zilio , Adriano Leidiane , Valim Valeria , Cunha Thiago Mattar , Louzada Junior Paulo , Rocha Eduardo Melani
Published: October 2018

For decades, neurologic and other extra glandular manifestations have been described in Sjögren’s syndrome (SS). More recently, neuropathic, psychological and cognitive alterations are being considered part of the disease. The lacrimal glands (LG), the ocular surface (OS), salivary glands (SG) and the central nervous system (CNS) are integrated to modulate the autonomic functions and, not just those organs, but also the hippocampus, which is linked to the autonomic nervous system, and modulate behavior responses appears to be compromised in the SS. Recent studies confirm that the tryptophan/kynurenine pathway (TKP) can be stimulated by interferon-γ (IFN-γ) and other cytokines, activating the indoleamine-pyrrole 2,3-dioxygenase (IDO) in SS. This pathway interferes on serotonergic and glutamatergic neurotransmission, mostly in the hippocampus, and other structures of the CNS. Although not demonstrated, it is plausible that this constant interference induces clinical signs of SS, and contributes to the discrepancy between symptoms and signs, towards manifestations of hyperalgesia and depression in patients with SS. Therapeutic strategies are being reexamined and new options designed and tested to regulate the involved steps of the TKP. In the future, the application of this concept may offer a clue to the mosaic of manifestations of SS.
Benefit-Cost Analysis of Building Information Modeling (BIM) in a Railway Site
Authors: Shin Min Ho , Lee Hye Kyung , Kim Hwan Yong
Published: October 2018

Recent technological improvements have made abundant changes in construction industry. In specific, some technical applications, such as Building Information Modeling (BIM) opens up many possibilities. Some studies have articulated the use of BIM and its advantages in construction, but most of them are theoretical, not practical. This study is to provide an insight to such obstacles in BIM research. By investigating a real project that could utilize BIM in planning and construction phases, the authors try to investigate a possible outline of advantages in BIM implementation. The study area was set to a railway construction site in South Korea. The site covers a multiple railway tracks, stations, telecommunication facilities, infrastructure facilities, railway structures, and so numerous. In the site, the authors have identified 12 errors in 7 projects that could be prevented if BIM was utilized before the construction. The total upfront costs required to provide a BIM for 7 projects were $116,348. On the other hand, the total costs required to fix the errors in 7 projects were $166,486. This can be regarded as the benefits of using BIM because if BIM was implemented then the associated errors are easily replaced. Therefore, the benefit-cost ratio can be estimated as 1.32 for one-month delay and 1.36 for a three-month delay.
Development of an Improved Carotenoid Extraction Method and Characterisation of the Carotenoid Composition under Oxidative and Cold Stress in the Rock Inhabiting Fungus Knufia Petricola A95
Authors: Flieger Kerstin , Knabe Nicole , Toepel Jörg
Published: October 2018

Black yeasts are a highly specified group of fungi, which are characterized by a high resistance against stress factors. There are several factors enabling the cells to survive harsh environmental conditions. One aspect is the pigmentation, besides the melanin black yeasts often display a highly diverse carotenoid spectrum. Determination and characterization of carotenoids depend on an efficient extraction and separation, therefore especially for black yeast, characterized by thick cell walls specific protocols are needed to ensure analyses regarding stress responses in these fungi. Here we present both, a method to extract and analyze carotenoids and the unusual carotenoid composition of the black yeast Knufia petriola A95. Mechanical treatment combined with an acetonitrile extraction gave us very good extraction rates with a high reproducibility. The presented extraction and elution protocol allows the separation of the main carotenoids (7) in K. petricola A95 and should be suitable for the detection of additional carotenoids in other species. K. petricola A95 displays an unusual carotenoid composition, with mainly didehydrolycopene, torulene and lycopene. The pigment composition varied in dependency to oxidative stress but remained relatively constant if the cells were cultivated under low temperature. Black yeasts are a promising source for carotenoid production and other substances. To unravel the potential of these fungi new methods and studies are needed. The established protocol allows the determination carotenoid composition in black yeasts. Oxidative stress results in an adaptation in pigment composition in K. petricola A95. Future experiments have to be carried out to determine if didehydrolycopene functions as a protective agent itself or if it serves as a precursor for antioxidative pigments like torulene and torularhodin, which could be produced after induction under stress conditions.
Explore the Parametric Variations on Different Doping Profiles of MOSFET for Analog and Digital Applications
Authors: Ullah Muhammad S , Fouad Emadelden , Domi Xhino  M.
Published: October 2018

The VLSI industry is facing parasitic effects that trouble development in the nanoscale domain. However, instead of replacing the traditional MOSFET design, it would be more advantageous to apply different doping profiles and discerning which deal with specific parasitic effects the best. With a review of Gaussian doping, Uniform doping, and Delta doping profiles and analysis of the FET technology characteristics that use these doping profiles, a comparison can be made among them for integrated circuit design engineers. These doping profiles are compared based on how well they perform against non-ideal and ideal environments. Also, both digital and analog performance are measured to ensure the uniqueness of each doping profile that is present. After getting a list of benefits from each doping profile, it is derived to determine which doping profile works best against a host of parasitic effects and what type of application do these doping profiles have
Components of Savings Accumulation in Nigeria: An Empirical Evidence
Authors: Ogbodo Chinedu Joel
Published: October 2018

The paper investigated the components of savings accumulation in Nigeria over the period 1980 to 2017. Secondary data were collated from World Development Index (WDI). In evaluating the objectives, the study employed the Auto Regressive Distributive Lag (ARDL) and Vector Error Correction Model (VECM) estimation methods. The key findings of the study show that the components of savings identified in literature understudied in the paper specifically, GDP per capita, foreign direct investment, financial deepening, interest rate, inflation rate exchange rate significantly influence savings accumulation in Nigeria either in short run, long run or both. Financial deepening was found statistically significant but influences savings negatively. Inflation rate was statistically insignificant although negative. The result from the VECM causality test revealed that short run and long run causal relationship exist between savings and the afore mentioned components in Nigeria. Hence, the study recommends careful manipulation of the identified savings components in a manner that they will not yield a counterproductive result in the economy rather contribute to the growth of savings and ultimately, the growth of Nigeria economy as a whole. It further recommends that the Nigerian government through its financial institutions encourage savings from both small and big savers which to large extent will assuage the perceived undeserved influence of financial deepening on savings accumulation.

Native Americans are the single most underrepresented racial group in American higher education today; those enrolled in college are also disproportionately first-generation students. In order to help universities attract and retain Native American students, this study utilizes the four R’s of indigenous research to document the motivations of first-generation Native American students to attend and remain at a mid-sized public university in the northwest. Student participants report that social and cultural support were key factors in their decisions to attend and remain at their institution. Implications of these findings are discussed, and recommendations are made to higher education institutions seeking to attract and retain Native American students.
Sentiment Analysis and Social Networking Sites: A Case Study
Authors: Mishra Deepanjali
Published: October 2018

Sentiments are the hormones of social networking sites. They trigger human emotions and emotions initiate social communication. All raw and polished communication that happen in social networking sites in form of chats, comments, scraps, tags, likes, photographs, etc are the result of an outpour of the bag of human sentiments. The objective of this research paper is to make an attempt to identify the various factors for identifying the role played by social networking sites on human emotions Social media is such a development that modern technology would always boast of, yet it cannot be denied that this media primarily functions with sentiments. Sentiments are to social media what fuel is to fire. Whether it is youth or age, whether it is house or office, whether it is man or woman every section of the society has contributed to the working, development and sustenance of the social media. Society, in other words, has fallen prey to these social networking sites. And the fundamental cause behind such addiction is "the role sentiments play” in them. Too much of sentiments seasoned with a pinch of logic sometimes provide us with a real fun platform for our society. Perpetual exchange of emotions in social networking sites are the main reason responsible for making them our most emphatic guardian who is considered to be the most trustworthy companion. However, disastrous bargain with the human sentiments in social networking sites may prove to be harmful and hazardous. The paper intends to explore this intense association of sentiments with social networking sites with identification of various steps to create awareness and to be excessively involved with the virtual world that may lead to disastrous effects. This study will help various other research activities carried out in information and management field as well firms planning to adopt and implement the possible ways of removing ignorance and open up various scope of research on the topic of social networking sites.
Business Process Configuration according to Data Dependency Specification
Authors: Parody Luisa , Gómez-López María Teresa , Varela-Vaca Ángel Jesús , M. Gasca Rafael
Published: October 2018

Configuration techniques have been used in several fields, such as the design of business process models. Sometimes these models depend on the data dependencies, being easier to describe "what" has to be done instead of "how". Configuration models enable to use a declarative representation of business processes, deciding the most appropriate work-flow in each case. Unfortunately, data dependencies among the activities and how they can affect the correct execution of the process, has been overlooked in the declarative specifications and configurable systems found in the literature. In order to find the best process configuration for optimizing the execution time of processes according to data dependencies, we propose the use of Constraint Programming paradigm with the aim of obtaining an adaptable imperative model in function of the data dependencies of the activities described declarative.

This paper aims to study the effect of raschig ring packing patterns using Computational Fluid Dynamics (CFD). CFD module of particle tracing was established to measure particles diffusing through the packed bed. The support raschigs catalyst was modeled in three patterns within a tubular reactor – namely, vertical staggered, chessboard staggered and reciprocal staggered pattern. A case study of Dry Methane Reforming (DMR) was investigated at 600°C, 1 atm. The study of Mean Resident Time (MRT) and E(t) function were investigated to identify the packing pattern performance. The results showed that the minimum value of the E(t), which means the flow behavior, was close to ideal plug flow behavior. MRT can be used to systematically identify the deviation from the ideal plug flow reactor of the three different packing patterns.

The purpose of this is study to examine the impact of foreign direct investment (FDI) on GDP growth in Afghanistan with particular emphasis on Chinese FDI under the Belt and Road economic strategy. Belt and Road Initiative (BRI) assumed to be benefiting a poor country like Afghanistan; the newly developed ARDL-bound testing procedure is used for the period of (2006 – 2016). The result show that long run cointegration holds between economic growth and Chinese investment. Granger causality results indicate that there is bidirectional short and long run causality between economic growth and Chinese investment. These finding are supported by impulse response analysis and suggest the applicability of modernization theory to explain economic growth and Chinese investment relationship. The results also reveal that agriculture and services has a deteriorating impact on economic growth. Moreover the importance and feasibility of Wakhan corridor and link directly Afghanistan with China, also the expending of CPEC to Afghanistan for discovering easy route to middle Asia and Europe.

There are many molecules used as drug carrier. TUD-1 is a newly synthesized mesoporous silica (SM) molecule possess two important features; consists of mesoporous so it is very suitable to be drug carrier in addition to that it has the ability to induce apoptosis in cancer cells. However, the effect of TUD-1 appears to act as cell death inducer, regardless of whether it is necrosis or apoptosis. Unfortunately, recent studies indicate that a proportion of cells undergo necrosis rather than apoptosis, which limits the use of TUD-1 as a secure treatment. On the other hand, lithium considered as necrosis inhibitor element. Hence, current study based on the idea of production a new Li/TUD-1 by incorporated mesoporous silica (TUD-1 type) with lithium in order to produce a new compound that has the ability to activate apoptosis by mesoporous silica (TUD-1 type) and at the same time can inhibit the activity of necrosis by lithium. Herein, lithium was incorporated in TUD-1 mesoporous silica by using sol-gel technique in one step synthesis procedure. Moreover, lithium was incorporated in TUD-1 with different loading in order to form different active sites such as isolated lithium ions, nanoparticles of Li2O, and bulky crystals of Li2O. The ability of the new compounds to induce apoptosis and prevent necrosis was evaluated on three different types of cancer cell lines which are; liver HepG-2, Breast MCF-7 and colon HCT116. The obtained results show that Li/TUD-1has the ability to control necrosis and thus reduce the side effects of treatments containing silica in the case of lithium has been added to them, especially in chronic cases. This has been demonstrated by the significant increase in the IC50 value and cell viability comparing to control groups. Consequently, the idea is new, so it definitely needs more develop and test with materials that have more apoptotic impact than silica in order to induce apoptosis without induction of necrosis.

Ischemic neuron loss contributes to brain dysfunction in patients with cardiac arrest (CA). Histidine–tryptophan–ketoglutarate (HTK) solution is a preservative used during organ transplantation. Can HTK also protect neurons from severe hypoxia (SH) following CA? We isolated rat primary cortical neurons and induced SH with or without HTK. Changes in caspase-3, hypoxia-inducible factor 1-alpha (HIF-1α), and NADPH oxidase-4 (NOX4) expression were evaluated at different time points till 72 h. Using a rat asphyxia model, we induced CA-mediated brain damage and then completed resuscitation. HTK or sterile saline was administered into the left carotid artery. Neurological deficit scoring and mortality were evaluated for 3 days. Then the rats were sacrificed for evaluating NOX4 and H2O2 level in blood and brain. In the in vitro study, HTK attenuated SH- and H2O2-mediated cytotoxicity in a volume- and time-dependent manner, associated with persisted HIF-1α expression, reductions in procaspase-3 activation and NOX4 expression. The inhibition of HIF-1α abrogated HTK’s effect on NOX4. In the in vivo study, neurological scores were significantly improved by HTK. H2O2 level, NOX4 activity and NOX4 gene expression were all decreased in the brain specimen of HTK-treated rats. Our results suggest that HTK acts as an effective neuroprotective solution.
Vitamin- C retention in commercially available mung bean (Vigna radiate) sprouts

Published: October 2018

The present study was conducted with an objective to assess the retention of vitamin– C over a time period in commercially available mung bean sprouts (CMBS). Mung beans sprouted samples were procured from market (CMBS) and compared with mung beans sprout samples processed at laboratory scale (LMBS) in controlled condition. Both sprouted samples were stored at 7˚C in refrigerator. Shelf life studies were conducted periodically on physical, chemical and microbiological parameters during the storage time period of 0-96 hours. During shelf life studies, several differences were observed among CMBS and LMBS samples. Keeping quality of sprout samples in terms of its appearance and odour started deteriorating after 48 hours in CMBS, and 96 hours for LMGS. Shoot length increased significantly till 48 hours in CMBS whereas till 72 hours in LMBS. Moisture loss in CMBS and LMBS was 22% and 28% respectively. Titrable acidity in CMBS and LMBS decreased with increase in storage period. Vitamin- C content shows significant increase till 24 hours in CMBS, till 48 hours in LMBS followed by subsequent decrease thereafter. Vitamin- C retention in CMBS was 2%, while 16.6% in LMBS. Microbial load was considerably higher in CMBS as compared to LMBS, with rapid increase in Coliform count during storage in CMBS, while in LMBS it was not detected. Thus it was concluded that, to gain optimal vitamin- C content CMBS must be consumed within 24 hrs. However LMBS should be consumed within 48hrs, yet its vitamin – C retention was comparatively more till 96 hours of storage.

Published: October 2018

The present study was attempted to assess the extent of aflatoxin contamination from presence of discoloured kernels (DKs) in ready-to-eat (RTE) processed whole groundnut products sold in Hyderabad city in southern India. A total of 34/56 fried (FG) and roasted and salted groundnut (RSG) samples were examined for the presence of DKs. DKs were segregated from the samples and subjected to aflatoxin analysis either as single DK or pooled DKs using HPLC methods. The aflatoxin content in the RTE samples was computed from the aflatoxin levels determined in the segregated DKs as well as in the non-discoloured kernels (NDKs) and ingredients used for coating such as flour and spices. Analysis of 77 single DKs indicated presence of aflatoxins in 31% of the DKs at levels ranging from 0.007 to 1383.4 μg/g. Analysis of 17 pooled DK samples indicated presence of aflatoxins in 13 pooled DKs at levels ranging from 0.142-357.3 μg/ pooled DKs. The total aflatoxin content in the RTE samples calculated from aggregate of aflatoxin levels in DKs, NDKs and other components ranged from 0.001 to 2.779 μg/g sample respectively and was contributed mostly by DKs (90%). Aflatoxin was not detected in 22 samples that did not contain DKs. Presence of DKs in RTE groundnut products for direct human consumption can become potential sources of aflatoxin exposure to the consumer and methods to prevent their entry into processed foods containing whole kernels at post processing is urgently required.

Published: October 2018

The study was aimed to evaluate the effect of sunlight on vitamin D and calcium status among the college girls, aged 18 – 22 years. One hundred and fifty girls were selected out of which 45 with vitamin D deficiency were considered for experiment. The participants were divided into three groups of 15 each: Experimental I - curd supplementation, exposure to sunlight and nutrition education; Experimental II - exposure to sunlight and nutrition education and Control group with no intervention. Anthropometric measurements, blood haemoglobin, serum vitamin D and calcium were analysed before and after supplementation for 50 days. In the experimental group I, there was a mean increase of 3.22 ng/ml of vitamin D and was significant at 1% level and in the experimental group II the increase was 1.03 ng/ml (significant at 5% level). There was a mean difference of 1.57 ng/ml in the control group which was not significant. The mean initial calcium level in the experimental group I was 9.33 mg/dl and the final value is 9.67 mg/dl and the increase was significant at 1% level. The experimental group II had a mean initial calcium level of 9.36 mg/dl and the mean final value of 9.56 ml g/dl. The mean difference of 0.05 mg/dl was noted in serum calcium before and after supplementation in the control group. The experimental group I showed a positive correlation of 0.035 between vitamin D and sunlight whereas in experimental group II and control group there was a negative correlation of 0.045 and 0.072 respectively. It can be concluded that sunlight had an effect on vitamin D status and the calcium level of the participants further highlighting that sunlight exposure is an effective method of improving the vitamin D status.
