The study modeled the dynamic interaction between exchange rate, interest rate and agricultural export earnings using panel VAR Model. The specific objectives of the study include to; interdependencies in the dynamic interaction between exchange rate, interest rate and agricultural export earnings, parameters of panel VAR model using PVAR Stata code developed by Abrigo and love, determine the shocks associated with their dynamic interactions between these variables, investigate direction of causality between interest rate, exchange rate and agricultural export earnings from six African countries and make appropriate recommendations. The data used for the study was secondary data extracted from index mundi website and world data indicators for the period of 40 years (1980-2020). The data was on exchange rate, interest rate and agricultural export earnings. Geographically, the six African countries include; Algeria, Angola, Egypt, Libya, Gabon and Nigeria. The study uses vector Autoregressive model estimation results with PVAR Stata code developed by Abrigo and love. The post estimation test on the Vector Autoregressive (VAR) model shows a contemporary Co-efficient of Correlation analysis. It was found that lending interest rate and exchange rate are negatively associated with Co-efficient of Correlation of (-0.0873). Also, it was found that there exist a positive association between exchange rate and agricultural export earnings. Also, there is a positive association between lending interest rate and agricultural export earnings. The inverse roots of a characteristic polynomial of the estimated Panel VAR model satisfied the stability condition (of the diagnostic test) since no root lied outside the unit root circle. Therefore, the estimated VAR is stable. However, it was confirmed that there is no directional relationship that exist between the variables. Also, the results show that exchange rate and lending rate have positive on agricultural export earnings, whereas exchange rate is likely to reduce the level of lending interest rate slightly. Therefore, it is recommended that in estimating the dynamic interaction between variables in a panel data system, there is need for the inclusion of the lags of the response variable among the determinants to measures the dynamic interaction as well capture heterogeneities in the series and also, policies should be formulated to stabilized exchange and lending rates in order to improve and strengthen the countries’ agricultural economy amongst others

This study investigated the association that exists between the audit attributes and the financial reporting quality of firms listed under insurance sector of Nigerian economy. The study had five objectives that include the investigation of audit type, audit tenure, joint audit, industry specialised audit and audit fee on the financial reporting quality as was measured by discretionary accruals using modified Jones model. The use of ex post facto research design was adopted which necessitated collection of secondary data from the annual report of the twenty two sampled insurance firms, from 2011 to 2020 financial years. The data were analysed using statistical tools like descriptive statistics, correlation analysis, fixed effect and random effect model tests, where Hausman test was used to choose the best between the two models, as a requirement for running panel data regression analysis. The empirical result therefrom indicates that audit type has positive and no significant effect on the financial reporting quality. Further result shows that audit fee has inverse statistical significant effect on financial reporting quality at 1% level. Nonetheless, audit tenure, joint audit and industry specialised audit have negative but no significant effect on financial reporting quality of the listed insurance firms. The study recommendations emanating from the findings among others maintain that the regulatory bodies should reaffirm that audit firms rely on professional benchmark-based fee calculation in every audit engagement, bearing in mind that any compromise or cut in audit fee, possibly as a result of competing for clients, would undermine the quality of financial reporting in the sector

Educational policy implementation in Nigeria have been hit in the main by incidences of poor availability of physical facilities/infrastructures. This paper examines public policy implementation and availability of facilities/infrastructures in primary and junior secondary schools in Rivers State between 2008 – 2018. The paper is guided by the single proposition that, there is no significant difference in universal basic education policy implementation and the availability of facilities/infrastructures in schools in Rivers State. The paper is anchored on the Programme Evaluation Theory as its analytical framework. A sample of 600 schools was purposively derived from a population of 1,332 of both primary and secondary schools in the state. This was evenly distributed to the 3 senatorial districts in the state. Data for the paper was generated via questionnaire distributed to the 600 principals and head teachers of the selected schools, and via secondary sources such as books, UBE policy documents, etc. Generated data was analyzed using Gross Enrolment Ratio Growth Rate, Teacher/Pupil Ratio, T-test and Diagrammatic Representation. As part of its findings, the paper revealed that, the situation of education in the state is not in consonant with the objectives of the Universal Basic Education (UBE) policy. Also, that the state government’s stance for free compulsory basic education is only but an elusive agenda. As such the paper recommends that; the state government should devise more inclusive strategies that will ultimately seek to enforce the free education for every child within the UBE age. This can be done by adopting the “parent-teacher team” of monitors and enforcers of this policy

An outstanding problem for the service providers of Electricity in Port Harcourt City Local Government area of Rivers State and most cities of Nigeria is the unwillingness to pay the prescribed bills by the consumers. The unwillingness to pay can be traced to unrealistic electricity bill from the service provider to consumers as well as the influence of demographic and socioeconomic factors on the side of consumers. This study identifies how the demographic and socioeconomic factors influences consumers’ willingness to pay electricity bill. Logit, probit and tobit models were used in modelling out consumers’ willingness to pay electricity bill with the aid of stata software version 16, having the demographic and socioeconomic factors as the independent variables. The study also provided quantitative evidence of the correlation between the demographic, socioeconomic factors and consumers’ willingness to pay electricity bill. Research questionnaires with a sample size of 1338 was adopted as the source of data for the study. The results show that there is positive correlation between consumers’ willingness to pay for electricity bill, demographic and socio-economic factors in Port Harcourt City Local Government Area of Rivers State. The correlation coefficient of Consumers’ willingness to pay with respect to the demographic and socioeconomic factors are 0.1828 and 0.1001 respectively while the correlation coefficient of the demographic factor with respect to the socioeconomics factor is 0.1755. The results of the Probit, logit and Tobit models were compared on the basis of Akaike Information Criterion (AIC) and Bayesian Information criterion (BIC) and it was found that the probit model with AIC and BIC values of 952.404 and -30.771 respectively was the best fitted model in modelling Consumers’ willingness to pay for electricity bill in Port Harcourt City Local Government Area of Rivers State. The coefficients of the probit model associated with the demographic and socioeconomic factors that influences consumers’ willingness to pay for electricity bill in Port Harcourt City Local Government Area are 0.5676279 and 0.3529775 respectively. These figures represent 56.7% and 35.3% increase in the Consumers’ willingness to pay for a unit increase in the demographic and socioeconomic factors. The probit model and the associated confidents from this study offers a useful guide to the electricity service providers to arrive at an acceptable electricity bill to electricity consumers in Port Harcourt City Local Government Area of Rivers state.
Hepatotoxicity Secondary to Ribociclib and Echinacea
Authors: Clara García González
Published: August 2022

The consumption of medicinal herbs has increased in recent years. There is little evidence with regards to their real benefits and a small number of scientific papers about adverse effects. A case of a 55-year-old woman is presented, with recent diagnosis of luminal A de novo metastatic breast cancer. She starts first-line treatment with Ribociclib in combination with letrozole. After 2 months, a partial response is achieved. However, the patient presents grade 4 hepatotoxicity. She had started to take Echinacea two months ago. Other causes of liver failure are ruled out. Both Echinacea and Ribociclib present hepatic metabolism through cytochrome p450, which means that there could be a potential interaction between them. This is the first reported case of a potential interaction between Ribociclib and Echinaea. We highly recommend avoiding the concomitant use of both medications.

Indonesia has one of potential plants as an herbal medicine, called Lime (Citrus aurantifolia) and Kaffir Lime (Citrus hystrix DC), both used for different purposes such as cooking, seasoning and traditional medicine. Both plants are derived from the family of Rutaceae which belongs to shrubs that have many branches and twigs. This study aimed to carry out the antibacterial assay of the Rutaceae family. This study used a literature study approach, which references were obtained through 3 Journal sources, namely Google scholar, pubmed, and thscience direct. Furthermore the selected research article which met the criteria was reviewed. Based on the search done, it obtained 7 articles and identified antibacterial activity of lime and Kaffir Lime. The result confirmed that both have antibacterial compounds against bacteria Escherichia coli, and Staphylococcus aureus because they contain secondary metabolite compounds consisting of alkaloids, flavonoids, tannins, and essential oils.
Sozio-technischer Wandel durch Europäisierung?
Authors: Wolff Annika
Published: August 2022

For some decades, waste prevention has been Germany’s top priority when it comes to waste management. However, this has not resulted in significantly smaller amounts of waste. Therefore, this comparative study of Munich and Cologne asks whether new European policies have been able to influence these cities’ socio-technical waste management systems on a local level. At the interface between political science and infrastructure research and focusing on incrementally unfolding EU-induced change on the local level, this study provides important insights for Europeanisation research, urban studies and the social sciences of technology.
Public Political Risk Investment Insurance
Authors: Vujinović Nataša
Published: August 2022

This book deals with public political risk investment insurances, providing comparative analyses of MIGA’s, the German and 7 further currently operating EU MSs’ public PRI schemes. In spite of the EU’s partly exclusive competence in this field, the MSs still operate their national PRI schemes. The comparative analyses have enabled the identification of best practices among these schemes. As it is the high time for the EU to exercise its competence concerning PRI, this book considers the options and suggests a way forward. In that sense, annexed to the book is the author’s proposal for an EU Directive on harmonisation of the main provisions concerning public PRI for FDI in third countries.
Mit- und Selbstbestimmung von Religionsgemeinschaften in der Zusammenarbeit mit dem Staat
Authors: Schierning Sophie
Published: August 2022

The Right to Autonomy of religious groups is a cornerstone of German constitutional law for which there is no English equivalent. After analysing the general legal status of religious groups in both countries, the author looks at how their legal position differs in two areas that, in Germany, are particularly characterised by the Right to Autonomy and the Principle of Neutrality: Religious education and institutional chaplaincy. Religious pluralisation is kept in mind throughout the book. Overall, it becomes apparent that English law, much like European law, understands religious freedom in individual and collective rather than corporate terms.
Kapitalschutz bei den atypischen Personenhandelsgesellschaften de lege lata und de lege ferenda
Authors: Tsotsa Ioanna
Published: August 2022

Geared towards scholars and practitioners, the thesis examines the capital protection in case of (limited) partnerships if no natural person is unlimitedly liable for corporate obligations. Such “atypical” (limited) partnerships are equated with corporations by means of specific legal provisions, which are aimed at supplementing the creditor protection regime. Dogmatically well-founded, the author demonstrates that specifically the capital protection is still fragmentary and develops a comprehensive and pragmatic reform proposal. Thus, the thesis does not only offer a valuable analysis of the applicable legal regime for the benefit of advisors, companies, and scholars but also a contribution to the further modernization of partnership law.
Interkulturelle Kompetenz im Krankenhaus
Authors: Schmidhuber Martina
Published: August 2022

This book focuses on two major challenges currently facing hospitals: On the one hand, it considers our increasingly ageing society because this is reflected in an increasing number of patients with age-related diseases, such as dementia. On the other hand, it analyses the fact that communication with people with dementia from a migration background and their relatives requires special skills in a hospital. Based on theoretical concepts, case analyses and experiences of physicians, the study shows how doctors’ communication with patients with dementia and their relatives can be successful in an intercultural setting.

Published: August 2022

Introduction/Aim: The use of macronutrient and micronutrient foods is associated with the duration of sleep. This study aimed to determine the effect of zinc supplements on the sleep quality of older adults. Methods: The current parallel randomized clinical trial study was performed using a convenience sampling method. One hundred and fifty older adults who met the inclusion criteria were assigned to intervention and control group. The participants in the intervention group received a daily dose of 30 mg zinc supplementation pill for 70 days and the control group did not receive any supplement. Sleep quality was measured using the Pittsburgh Sleep Quality Index (PSQI). Serum zinc level in both groups was measured through the auto-analysis method. The questionnaire was completed and the serum level of zinc was measured twice, before the intervention and 70 days after the intervention. Results: Both groups were homogeneous in terms of demographic variables, sleep quality, and serum zinc level before the intervention. Of all, 73.3% of older adults in the intervention group and 74.7% of older adults in the control group had poor sleep quality. Sleep quality in the intervention group, as compared with the control group, significantly improved after the intervention. Furthermore, serum zinc levels in older adults in the intervention group, as compared with the control group, significantly increased after the intervention. Conclusion: Based on the results of this study, it is recommended to utilize zinc supplementation as a new therapeutic approach for improving sleep quality in older adults.

Authors: Đaković Miloš , Inđić Milica , Cicmil Danica
Published: August 2022

Financial exchanges are the basic form of a country's financial market. The subject of this research is the Belgrade Stock Exchange, while the aim of the paper is to analyze the main indicators of the business of the stock exchange as a single company. The analysis covers the period from 2017 to 2020, where in addition to observing the basic items of assets, liabilities, income and expenses of the stock exchange, we also deal with the ratio analysis of liquidity, indebtedness, coverage, activities and profitability of the stock exchange. The results indicate a pronounced liquidity of the market and debt control, but very low profitability of the company itself. Financial analysis also provides additional more precise insight into the business of the stock exchange as a single company. The paper also provides a basis for further research in terms of comparative analysis with other developed stock exchanges in the world.
« Au détour des chemins battus » : topique et topologie dans les histoires comiques
Authors: Debaisieux Martine
Published: August 2022

Portant sur six histoires comiques qui couvrent la période 1623-1657, mon analyse se focalise sur une manifestation particulière de la topique « mauvaise rencontre », s’articulant autour des notions de détour et d’égarement. Créant un effet de digression sur le parcours diégétique, les séquences considérées mettent explicitement en rapport topique et topologie puisque l’élément déclencheur est un écart, une erreur ou « aberration », dans l’itinéraire du protagoniste.  S’étant éloigné du « grand chemin », celui-ci est assailli par un personnage fou / sauvage / possédé, ou par une foule en furie.  Ces épisodes à résonnance grotesque se concluent sur une perte de repères et/ou sur une mise à nu.  Leur repérage met en évidence un champ lexical qui rapproche la situation topographique de la désignation de personnages « délirants » (etym. – « sortir du sillon »).   En fin de parcours, une histoire comique plus tardive – Le Roman bourgeois (1666) – permet de constater un changement significatif dans la configuration topographique et le parcours des personnages.
Le topos de la rencontre chez Veiras et Foigny
Authors: Murvai Peter
Published: August 2022

La scène de la rencontre entre Européens et Utopiens dans les oeuvres de Denis Veiras et Gabriel de Foigny représente un topos narratif qui n’acquiert sa pleine signification que lorsqu’on le situe par rapport aux récits des voyages et aux textes utopiques antérieurs. Notre propos est de montrer que la configuration particulière du topo du contact dans les utopies louis-quatorziennes de Veiras et de Foigny est le résultat d’une évolution qui a conduit ces auteurs à mettre en question aussi bien les présupposés idéologiques de la littérature viatique classique que la formule narrative des utopies de la Renaissance.
Rabelais au risque de la topique
Authors: Garand Dominique
Published: August 2022

L’objectif de sérier l’ensemble des manifestations de la violence dans Pantagruel et Gargantua sera ici doublé par celui de cerner certaines questions théoriques et méthodologiques au sujet de la valeur opératoire des topos. Le choix de Rabelais pourra paraître hasardeux : ses « chroniques » présentent en effet un caractère hétérogène (tant du point de vue de la forme que du contenu) fort éloigné du « romanesque » tel qu’il s’est fixé par la suite dans la tradition française. De plus, s’il existe une topique à l’oeuvre dans le texte rabelaisien, il faudrait plutôt la chercher dans les corpus grec et latin, dans les récits populaires du Moyen Âge, dans l’épopée et la chanson de geste. Il y a donc quelque chose de paradoxal à faire de Rabelais l’un des « pères » du roman, à côté de Cervantès. Rabelais paraît signifiant davantage pour ce que la tradition littéraire n’a pas retenu de lui que pour la postérité de ce que son imagination s’est plu à inventer. J’utilise à dessein ce mot en rappelant le lien qui existe depuis l’Antiquité entre topique et invention. Inventer, c’est créer sans doute, mais c’est avant tout re-créer, exhumer, repêcher des matériaux disponibles, légués par la tradition. Dès lors, le geste créateur prend place dans la faculté d’exploiter au maximum les ressources des topos et de rendre ainsi à quelque chose de connu son caractère étonnant.
Du Paňcatantra aux « fables de Pilpay ». Composition textuelle et la transmission culturelle de la topique orientale-occidentale de l’amitié
Authors: Dubost Jean-Pierre
Published: August 2022

Le but de cet article est de définir les grandes lignes d’un traitement théorique de la topique de l’amitié dans une perspective de « littérature vraiment générale », pour reprendre le fameux titre d’Etiemble et de tracer les contours d’un questionnement théorique « orientale-occidentale » . En effet, de la nébuleuse indienne dont le Panca Tantra est ici le paradigme jusqu’aux innombrables variantes européennes en passant par la médiation arabo-islamique décisive (le Kalila wa Dimna d’Ibn Al-Muqqafah et ses nombreuses variations), il se trouve que l’un des plus grands intertextes, si ce n’est peut-être le plus vaste, de la littérature mondiale, est thématiquement structuré dès l’origine autour de la problématique de l’amitié. L’observation de ses mutations transculturelles et transgénériques nous permet de soulever un certains nombre de questions décisives quant au rôle de la récurrence topique dans cette immense métamorphose textuelle qui s’étend sur une période comparable à celle qui permet de délimiter le plus largement le champ de l’analyse satorienne (à savoir du roman grec du début de l’ère chrétienne à la fin de l’Age classique). Mais à la différence de ce champ proprement occidental (bien que l’origine en soit autant « romaine » que « syrienne »), l’intertexte de l’amitié indo-arabo-persan qui essaime ensuite en Europe est l’un des démentis les plus flagrants qui puissent être apportés à l’idée bien fausse d’une identité proprement occidentale de la littérature d’Occident. Au-delà de ces rappels historiques fondamentaux, l’article soulève les questions suivantes : dans quelle mesure est-il possible de dégager des constantes et de les déterminer comme telles dans un tel rhizome, puisque la traversée des cultures, des sociétés et des époques n’a cessé de re-contextualiser le sens à donner à l’idée d’amitié ? L’approche proposée tente d’apporter par cette enquête une réponse à l’une des questions les plus lancinantes de la méthode satorienne, à savoir la difficile mais nécessaire distinction entre analyse topique et analyse thématique, entre interprétation historique et analyse fonctionnelle d’inspiration narratologique.

Rydberg state excitation of atoms and molecules in ultrafast intense laser field
Authors: Shen Xing-Chen , Liu Yang , Chen Qi , Lü Hang , Xu Hai-Feng ,   Institute of Atomic and Molecular Physics, Jilin University, Changchun 130012, China
Published: August 2022

When atoms or molecules are irradiated by a strong laser field with pulse duration of tens of femtoseconds and intensity larger than 1013 W/cm2, they will generally undergo tunneling ionization, which will induce various non-perturbative and highly nonlinear phenomena. Investigations into the strong field physical processes is of significance in studying attosecond physics, molecular orbital imaging, ultrafast electron diffraction and advanced short ultraviolet light sources. While there is a relatively long history of the studies of tunneling ionization induced physics including high-order above threshold ionization (HATI), high-order harmonic generation (HHG) and non-sequential double ionization (NSDI), it is until recently to surprisedly find that in the tunneling ionization region, neutral atoms or molecules can survive in strong laser fields in highly excited Rydberg states. As a basic process of the interaction between ultrafast strong laser fields and atoms or molecules, such a Rydberg state excitation (RSE) has been viewed as an important supplement to the physical picture of the tunneling ionization. During the past several years, the extensive research attention has been paid to the RSE process in strong laser field. Various theoretical and experimental methods have been developed to investigate the strong field RSE of both atoms and molecules, to understand the underlying physical mechanism behind the recapture of the tunneling electrons and to reveal the quantum features and molecular structure effect in RSE. These advances have brought about an in-depth understanding and a systematic view of the atomic and molecular RSE in strong laser fields, as well as their relations to the other tunneling ionization induced physical processes such as ATI, HHG and NSDI. Here, we systematically review recent research progress of the atomic and molecular RSE in strong laser fields. We particularly focus on several aspects of this strong field process, i.e. the physical mechanism of the recapture, the quantum feature and the interference of different orbits, and the structure effect in molecular RSE. In addition, neutral particle acceleration and coherent radiation which can be induced by the strong field RSE, are also discussed. Finally, we provide a short summary and prospect of the future studies on the strong field RSE.
Årsaker praksisveiledere oppgir for å vurdere og stryke sykepleiestudenter i deres kliniske praksis

Published: August 2022

Mange sykepleiestudenter består kliniske praksisstudier selv om de ikke har oppnådd forventet læringsutbytte. Hensikten med denne studien var å belyse hvilke grunner praksisveiledere beskriver for å stryke sykepleiestudenter i deres kliniske praksisstudier. Datamaterialet fra et åpent spørsmål i et spørreskjema, ble analysert ut fra Malteruds modell for tekstkondensering. Studien viser: 1) Studenters manglende interesse og initiativ er en viktig grunn til å ikke bestå kliniske praksisstudier, 2) Praksisveilederne vektlegger at studenter har evne til å søke og motta veiledning, 3) Alvorlige feil som grunnlag for å ikke bestå praksis, 4) Praksisveilederes beskrivelser av samarbeid med utdanningsinstitusjonene. Praksisveiledere har behov for å samarbeide tett med praksislærer i sin vurdering av sykepleiestudenter og i tillegg har de et behov for vurderingsverktøy som bygger på en felles forståelse mellom akademia og praksis. Det er behov for å trygge praksisveiledere med økt formell veilederkompetanse.
Myths in psychology: psychological misconceptions among Spanish psychology students
Authors: Rodríguez-Prada Cristina , Orgaz Cristina , Cubillas Carmelo P.
Published: August 2022

Myths in Psychology are beliefs that are widely spread and inconsistent with the empirical evidence available within this field of knowledge. They are characterized by being relatively stable, resistant to change, and prevalent both among the non-academic population and among students and professionals within this discipline. The aim of this study was to analyse the prevalence of these myths among Spanish psychology students and the influence of three variables: the type of university, face-to-face (UAM) and online (UNED), the academic year in which participants were enrolled and familiarity with scientific dissemination. Results show that participants from the face-to-face university, enrolled in higher academic years and that reports familiarity with scientific dissemination believe less in myths than those from the online university, enrolled in lower years and that report no familiarity with scientific dissemination.
Novel Driver Strength Index highlights important cancer genes in TCGA PanCanAtlas patients
Authors: Belikov Aleksey V. , Vyatkin Alexey D. , Leonov Sergey V.
Published: August 2022

Background

Cancer driver genes are usually ranked by mutation frequency, which does not necessarily reflect their driver strength. We hypothesize that driver strength is higher for genes preferentially mutated in patients with few driver mutations overall, because these few mutations should be strong enough to initiate cancer.

Methods

We propose formulas for the Driver Strength Index (DSI) and the Normalized Driver Strength Index (NDSI), the latter independent of gene mutation frequency. We validate them using TCGA PanCanAtlas datasets, established driver prediction algorithms and custom computational pipelines integrating SNA, CNA and aneuploidy driver contributions at the patient-level resolution.

Results

DSI and especially NDSI provide substantially different gene rankings compared to the frequency approach. E.g., NDSI prioritized members of specific protein families, including G proteins GNAQ, GNA11 and GNAS, isocitrate dehydrogenases IDH1 and IDH2, and fibroblast growth factor receptors FGFR2 and FGFR3. KEGG analysis shows that top NDSI-ranked genes comprise EGFR/FGFR2/GNAQ/GNA11–NRAS/HRAS/KRAS–BRAF pathway, AKT1–MTOR pathway, and TCEB1–VHL–HIF1A pathway.

Conclusion

Our indices are able to select for driver gene attributes not selected by frequency sorting, potentially for driver strength. Genes and pathways prioritized are likely the strongest contributors to cancer initiation and progression and should become future therapeutic targets.
Maintenance of specificity in sympatric host-specific fig/wasp pollination mutualisms
Authors: Xie Hua , Yang Pei , Xia Yan , Kjellberg Finn , Darwell Clive T. , Li Zong-Bo
Published: August 2022

Background

Fig/wasp pollination mutualisms are extreme examples of species-specific plant-insect symbioses, but incomplete specificity occurs, with potentially important evolutionary consequences. Why pollinators enter alternative hosts, and the fates of pollinators and the figs they enter, are unknown.

Methods

We studied the pollinating fig wasp, Ceratosolen emarginatus, which concurrently interacts with its typical host Ficus auriculata and the locally sympatric alternative host F. hainanensis, recording frequencies of the wasp in figs of the alternative hosts. We measured ovipositor lengths of pollinators and style lengths in female and male figs in the two host species. Volatile organic compounds (VOCs) emitted by receptive figs of each species were identified using GC-MS. We tested the attraction of wasps to floral scents in choice experiments, and detected electrophysiologically active compounds by GC-EAD. We introduced C. emarginatus foundresses into figs of both species to reveal the consequences of entry into the alternative host.

Results

C. emarginatus entered a low proportion of figs of the alternative host, and produced offspring in a small proportion of them. Despite differences in the VOC profiles of the two fig species, they included shared semiochemicals. Although C. emarginatus females prefer receptive figs of F. auriculata, they are also attracted to those of F. hainanensis. C. emarginatus that entered male figs of F. hainanensis produced offspring, as their ovipositors were long enough to reach the bottom of the style; however, broods were larger and offspring smaller than in the typical host. Female figs of F. hainanensis failed to produce seeds when visited by C. emarginatus. These findings advance our current understanding of how these species-specific mutualisms usually remain stable and the conditions that allow their diversification.

Hydatid cyst of brain in an extremely rare entity. A case of primary hydatidosis of brain without any involvement of other areas is even rarer. Most commonly involved areas are liver and lung because of rich vascularity and vicinity to portal circulation. Central Nervous System (CNS) or most importantly cases of hydatid cysts of brain are very rare. This case report is about a 7-year- old girl, from eastern India, who presented with multiple hydatid cysts in cranial cavity. She presented with headache, sudden loss of balance, short time memory loss. On Magnetic Resonanace Imaging (MRI), multiple cystic lesions were noted in cranial cavity. Magnetic Resonance (MR) Spectroscopy findings were suggestive of hydatid disease. These cysts were removed through neurosurgical intervention. The diagnosis was confirmed by gross and microscopic examination. Importance of keeping hydatidosis as a differential diagnosis while working up cases of cystic Space-occupying Lesion (SOL) of the brain in children is evident here.

Introduction: Nosocomial infections are a major problem for hospitalised neonates due to increase in morbidity, mortality, duration of hospitalisation and costs of treatment. The magnitude of this problem varies from place to place and is unique to each place as per the organisms and their resistance pattern is concerned. There is need to develop local level surveillance data on incidence of nosocomial sepsis, causative organisms, their sensitivity pattern and periodically review antibiotic policy based on this information. Aim: To determine the aetiological agents of nosocomial sepsis and their antibiotic sensitivity and resistance pattern. Materials and Methods: This was a cross-sectional study in which the cases of nosocomial infections in neonates of > 35 weeks were studied from November 2018-October 2019 at Sriram Chandra Bhanja Medical College and Hospital (S.C.B.M.C.H) and Sardar Vallabh Bhai Patel Postgraduate Institute of Paediatrics (S.V.P.P.G.I.P) based on clinical findings, sepsis screen and blood culture. Blood culture is considered as gold standard for diagnosis of sepsis. Blood sample (1 mL) was collected under strict asepsis in Becton Dickinson and Company (BACTEC) and was sent for performing blood culture. The data was processed and arranged into distribution tables and cross tables using Statistical Package for the Social Sciences (SPSS) version 21.0. Results: Out of total 100 suspected cases of nosocomial sepsis, blood culture was positive in 46 (46%) of cases. Candida spp. was the most common obtained organism 9 (19.5%) followed by Klebsiella pneumoniae 8 (17.3%) and Staphylococcus aureus 8 (17.3%) each respectively. There was increased incidence of bacterial resistance to commonly used antibiotics and combinations of it, like ampicillin, gentamicin, cefotaxime, amikacin and piperacillin+ tazobactam among these bacterial isolates. Among the possible new combinations deduced from the observation, the combination of vancomycin+amikacin had sensitivity of 67.6% and can be considered as initial antibiotic combination of choice while combination with colistin and tigecycline should be reserved only for culture proven resistant cases or babies who continue to be deteriorating and critically sick while on previous combination. Conclusion: Candida spp. is the leading cause of nosocomial sepsis. Among bacterial organisms, Klebsiella pneumoniae and Staphylococcus aureus are most common. Most isolates are resistant to traditional antibiotics, hence new combination like vancomycin+amikacin are more appropriate empiric choice in present context and combination with colistin and tigecycline are reserved only for culture proven resistant sepsis.

Linseed (Linum usitatissimum) belonging to family Linaceae, is a blue flowering annual herb that produces small linseed varying from golden yellow to reddish brown color. In India linseed is mainly cultivated in Madhya Pradesh, Maharashtra, Chhattisgarh and Bihar. Phosphorus occurs in most plants at 0.1 and 0.4% on dry weight basis. Like nitrogen, phosphorus is also a constituent of important metabolites, like phosphorylated sugars involved in photosynthesis, respiration and other metabolic processes. The oilseeds require more amount of sulphur for its growth and development than other crops. Plant height was influenced by sulphur and phosphorus levels up to 60 DAS but at 90 DAS all sulphur and phosphorus interaction level produced plant population. Various yield attributes of linseed number of capsule/plant, seed/ capsule, seed yield/plant, stover yield/plant, 1000 seed test weight. The number of capsule/plant and seed /capsule significantly increased with decreased in sulphur and phosphorus levels. Important role 15 kg/ha sulphur and 40 kg/ha phosphorus to increase maximum number capsule and seed/plant. The increase in stover yield of linseed as a result of PXS application may be due to improvement in root development and vegetative growth. Yield and yield attributes also showed significantly effect of sulphur and phosphorus viz. number of capsule/plant, number of seed/capsule, seed yield/plant and stover yield/plant. 1000 seed test weight in sulphur showed non significant as compare to phosphorus. Tha plant height was significantly increase 15 kg/ha sulphur was at par 10 kg/ha of sulphur than phosphorus 40 kg/ha was at par in 30 kg/ha. Number of branches increased with decrease 40 kg/ha phosphorus and 15 kg/ha in sulphur was at with 10 kg/ha sulphur and 30 kg/ha phosphorus. The significant effect of sulphur and phosphorus on root length 40 kg/ha phosphorus was at par with 30 kg/ha and 15 kg/ha sulphur was at par with 10 kg/ha.

Objective: The aim of this study was to detect changes in white matter in patients with Parkinson's disease applied by diffusion tensor imaging to predict cognitive impairment.

Methods: Montreal cognitive assessment was applied to 50 Parkinson's disease patients to confirm cognitive decline (M: F = 41:9; age: 62.72±9.07 years) and to 20 Parkinson's disease patients with no cognitive impairment as a control (M: F =13:7; age 58.95±11.22). All patients underwent disease severity testing by using Modified Hoehn and Yahr Scale, Unified Parkinson disease rating scale and Diffusion tensor imaging (DTI) for the corpus callosum and cingulum including their involved parts to define affected tracts.

Results: In PD with cognitive impairment subjects, the cognitive affection correlated with abnormal DTI parameters of the corpus callosum and cingulum. There were FA or MD differences in both the corpus callosum and cingulum pathways. These findings were independent of age, sex and total white matter volume.

Conclusion: Patients with Parkinson's disease associated with cognition decline are detected by tractography changes of the corpus callosum and cingulum.
