description: The analysis of hexavalent chromium (Cr (VI)) is an important water quality monitoring for public health safe consumption. Many high-end instruments were accessible to detect total Cr precisely at parts per trillion. Because of high upkeep of instruments, important to recognise on field examination and adjusting to low-volume (green chemistry) was quite challenging. The potential methods of detecting Cr in on-spot field examination were colorimetry. Numerous scientists were carried out by lab or compact spectrophotometer using 1,5-diphenylcarbazide and ability to produce magenta at 540 nm absorbance. The detection limit was achieved as per the WHO regulation levels. Still the requirement of standardisation in the field analysis was not completely suitable for low-volume due to use of standard chemicals. So in our study, the regular method was evaluated with the colour science approach by uniform (Lab, HLab and XYZ) and non-uniform models (RGB) with spectrophotometer and different cameras (mobile and digital still) using its flash light. The study showed Cr (VI) analysis by mobile camera was able to detect at 20 ng/mL. This was far better than recent reported studies with microfluidic and nanotechnology. The analytical relation with ICP-MS and mobile for Cr (VI) was found to be 0.60 (RSE-6.2%) to 0.72 (RSE-6.72%) with adjusted r2 value > 0.98. We have found to be in good agreement of ~70% with 98% confidence level of uniform models than non-uniform. The use of one-time colour standard references of uniform models might be helpful through naked eye judgment and ability to detect at 100 ng/mL based on individual perceptions in field analysis. This will improve in determining the sample collection, site evaluation for remediation and involvement of public in the water monitoring programmes. Further studies have to be conducted in tuning models to detect as precisely like high-end instruments using various NIST SRM standards.

description: In order to know the present status of aqua-medicines used in aquaculture activities in Jessore district, Bangladesh a rigorous investigation was conducted with fish farmers and representative of pharmaceutical companies from January, 2016 to May 2016. An extensive assortment of aqua-medicines was comprehended throughout pond prepation and water excellence administration by the agrarians. Amongst them Zeo-Fesh, Zeo Prime, Ecolite, Megazeo plus, Geotox, Jv Zeolite, Acmes, Benthos, Pond life, were extensively used in field level. Disinfectants has precise significance; far and wide used by the agrarians and the furthermost prevalent disinfectants are Pathonil, Timen, Fmsen, Virex, Aquakleen etc., the reimbursements of disinfectants are to inhibit dissimilar categories of bacterial, fungal and viral diseases resembling gill rot, tail rot, dropsy etc. to uphold sanitized circumstance in pond apparatus and floorings and in some circumstances use to treat disease. Numerous aqua-medicines were established in the aqua-medicines retailers that were informed to be used as noxious gas reducer. The obtainable deadly gas reducer were gastrap, gas stop, gasonex plus, ammonil besides that, remunerations of using venomous gas reducer are to eliminate the lethal gas like NH3, H2S, CO2 etc. since the bottommost of pond to diminish concentration of ammonia. For upgrading of dissolve oxygen level, Oxyflow, Oxymax, Bio Care, Bio-Ox, Oxy-Gold, Oxy-A, Oxylife were extensively used in the study area. A number of aqua medicines were found in the aqua-medicine enterprise used as growth promoter in addition to upsurge yield performance like, Megavit Aqua, Aqua Boots, Aquamin, Acimix etc. were extensively used in study area. Countless pharmaceutical companies have been chronicled to marketplace these aquaculture healthcare products. Furthermost of the products have been promoted from diverse republics like USA, Thailand, Malaysia, Belgium, and China and values were inconstant, but appeared to be reasonable to agrarians. The contemporaneous investigation pointed out numerous restraints concomitant with the use of such aqua-medicines, comprising nonexistence of methodological acquaintance of agrarians about use of aqua-medicines.

description: This is the first approach to identification, abundance calculation; biomass analysis and diversity evaluation in two water bodies namely, Municipal pond and Bukvora baor at Jashore district, Bangladesh. The present study was conducted to find out the abundance and species diversity of plankton, water quality parameters in pond and baor environment. However, Municipal pond that is located at the central point of Jashore town and Bukvora baor that is located at sadar upazila in Jashore district. Study also concentrated on the comparison about abundance, species diversity and water quality parameters between pond and baor. Water samples were collected in each month throughout the study period from May, 2016 to August, 2016. Different water quality parameters such as air temperature, water temperature, dissolve oxygen; pH and transparency were measured in every month. The mean water parameters such as air temperature, water temperature, dissolve oxygen; pH and transparency were 30.4±2.30°C, 32.25 ± 2.6°C, 5.7±0.35 mg/l, 7.05 ± 0.39 and 19.9 ± 2.6 cm, respectively in pond. In baor, the mean water parameters such as air temperature, water temperature, dissolve oxygen, pH and transparency were 33.45 ± 1.19°C, 33.15 ± 1.49°C, 5.03 ± 0.15 mg/l, 8.45 ± 0.36 and 24.95 ± 2.6 cm, respectively. A total of 30 phytoplankton species have been found in the study area of which species under four groups; namely Cyanophyta (5), Heterokontophyta (3), Chlorophyta (11), Euglenophyta (2) have been identified and nine species were unidentified. Phytoplankton species distribution was not uniform. Chlorophyta species was most dominant group in both environments. Major four groups of zooplankton identified in study area both pond and baor; namely Cladocera (10%), Copepoda (55%), Ostracoda (3%), Rotifera (15%). In addition Nauplius (2%), Tunicata (4%), Insect larve (5%) fish eggs (6%) were also identified. Copepoda species was most dominant group in both environments.

description: Objectives: Oxidative stress seems to be involved in Rett syndrome (RTT). The aim of this study was to assess the antioxidant status in RTT children with MECP2 gene mutations with respect to healthy controls, and to explore novel blood antioxidant markers for RTT severity. Methods: In erythrocytes from RTT females aged 2–14 years (n = 27) and age-matched controls (n = 27), we measured the levels of malonaldehyde and the activity of two antioxidant enzymes, Cu/Zn-superoxide dismutase and catalase, by spectrophotometric assays. In leukocytes, the expression of metallothioneins, the main non-enzymatic antioxidants, was assessed by real-time RT-PCR. In nine selected RTT children, methylome analysis was also performed. Results: Blood of RTT patients showed increased lipid peroxidation and a dysregulated pattern of MT expression, while enzymatic activities did not change significantly with respect to controls. Moreover, we observed no epigenetic dysregulation in CpG-enriched promoter regions of the analysed genes but significant hypomethylation in the random loci. Conclusions: As the haematic level of MT-1A directly correlates with the phenotype severity, this metallothionein can represent a marker for RTT severity. Moreover, the attempt to link the level of blood oxidative stress with MECP2 mutation and specific clinical features led us to draw some interesting conclusions.

description: The present study was conducted on 10 hatchery owners at Chanchra under Jashore district. The study period was May to August 2015. Data were collected through questionnaire interviews by using personal interviews and participatory rural appraisal (PRA) tools. In the study area, maximum spawn production of hatcheries was 2500 kg and minimum 800 kg. About 50% brood fishes were collected from own pond, 30% were collected from other's hatcheries and rest of 20% were collected from natural sources. The hatchery owners maintained proper age and weight of broods for spawning and followed the guideline of hatchery operation so that the quality of spawn and fry those produced by them were good in quality. It was found that the hatcheries produced fish seed of a variety of species like Indian major carps, carpio, sarpunti, silver carp, grass carp, magur, shing etc. The hatchery production activities took place starting February and continued up to September. The quantity of fish seed produce varied from 25 to 75 kg per hatchling cycle depending on size and facilities of hatcheries. The price of fry in Jashore was being fixed by the hatchery owners. However, the price variation was seen due to seasonal variation, species and demand. The average price of fish seed was maximum in monsoon and minimum in winter. In general skilled technicians were involved in hatchery operation. Some hatchery owners were well experienced and operated their own hatcheries. The hatcheries in Jashore district were viable. The hatchery owners had improved their social status though hatchery income.

description: The study was conducted to assess the marketing and value chain of crab from Nijhum Dwip Island in Noakhali region during July 2015 to December 2015. Data were collected through questionnaire interview and tools of participatory rural appraisal such as focus group discussion. The Meghna estuary, tidal rivers and mangroves were the main sources of crab. Local people including the fishermen can collect the crabs and crab lets. The grading system varied depending on sex and size of the crab. The highest average price was found to be 200 BDT/kg for FF1 grade of female while the minimum price was found to be 500 BDT/kg for XXL grade of male. Crabs were mainly available in April, May, June, July, August, September, and October. It was found that 70% crab catchers were from the age group of 12-28 years, which were the main working force in the society. In the study area, 60% of the crab marketers had monthly income of BDT 9,000-20,000, the farmers living conditions were not up to the mark but the survey suggests that most of the crab marketers and exporters increased their income level. If crab fattening can be established, training can be provided, institutional and policy support can be offered to the farmers and good marketing facilities can be developed, crab can be an alternative source of income and sustainable livelihood for the coastal poor people.

description: Soft bottom macrobenthos are important component of the marine and coastal trophic chain. There has been sparse information regarding the distribution of soft bottom macrobenthos form the coastal water of Bangladesh. Consequently, the present study was an effort to reveal the diversity and abundance of macrobenthos in the Feni Estuary in a seasonal pattern together with the hydrological factors. A total of 17 taxa families of soft-bottom invertebrates were found over the two sampling seasons. The current study yielded a total number of 34,726 ind./m 2 (mean 2480ind./m 2) including 18,909ind./m 2 in wet season (mean 2682ind./m 2) and 15,817 ind./m 2 in dry season (2259ind./m 2). The highest density of soft-bottom invertebrates was in the wet season while the lowest number in the dry season. A total of 5 groups of macrobenthos were found over the two sampling seasons. The dominant group was Polychaeta that contributed 43.60% of the total soft-bottom invertebrates. The values of biodiversity indices were higher in dry season compare to the wet season in most of the sampling station during the study period.

description: La pandemia da Covid-19 ha dato origine a un dibattito sulla relazione tra forme insediative e diffusione del contagio che ha ripotato alla luce un tema carsico nel dibattito pubblico italiano: quello del divario tra Nord e Mezzogiorno, tra poli e aree interne. È sembrato che una delle conseguenze permanenti possibili dell’esperienza pandemica potesse essere un nuovo protagonismo del Sud e delle aree extrametropolitane, ma questa prospettiva, tutt’altro che remota, non può concretizzarsi se non dentro un cambiamento radicale del paradigma ipercapitalista che ha dominato gli ultimi decenni. In questa ottica si riflette sulla inadeguatezza del concetto di competitività dei territori, frutto della loro mercificazione e si comincia a costruire un approccio alternativo basato sulla loro desiderabilità, concetto di più difficile definizione che però tiene in conto i diversi aspetti – non solo economici – che spingono le persone a scegliere il luogo in cui vivere. Al di là delle intenzioni, il PNRR utilizza lo stesso lessico e conferma la stessa cultura economicista che ha caratterizzato le politiche italiane nell’ultimo trentennio, rischiando così di accentuare anziché ridurre le diseguaglianze territoriali.

description: The sequential dehydration reaction of benzene-1,4-diboronic acid with pentaerythritol in the presence of polyethyleneimine (PEI) led to polymeric 3-benzo-2,4,8,10-tetraoxa- 3,9-diboraspiro[5.5]undecane, resulting in the formation of a PEI-coated boronate nanoparticle (BNP) with a mean diameter of 121 ± 43 nm through the spontaneous self-assembly. Subsequently, noble metal deposition on the boronate particle (M/BNP, M = Ru, Pd and Pt) was successfully achieved by NaBH4 reduction of RuCl3, and in the presence of BNP. Exploration of boronate-based catalytic systems applicable to the conversion of biomass to chemicals revealed that Ru/BNP has excellent catalytic activity for the hydrogenation of levulinic acid to γ-valerolactone (GVL) in H2O under 0.8 MPa of H2 at 100 °C; after 4 h, the reaction afforded GVL in 94.6% yield. The catalytic performance and recyclability of Ru/BNP in the reaction were investigated.

description: This paper aims at providing a conceptual framework to display how the Italian plan for recovery, under the next-generation goals, can “absorb” the disparities inside each regional context and how the local systems can differentiate the response to global challenges. The transition towards a more sustainable and innovative Europe is the main objective of the European Union and its policies. Considering the two pressing crises to tackle, namely, climate change and the COVID-19 pandemic, transformative development is gaining increasing momentum. Nowadays, processes of adaptation and transition are increasingly driving urban and territorial transformations. A reinterpretation of the Reggio Calabria Metropolitan Strategy is proposed to sharpen spatial targeting towards resilience and transition in a particular “fragile” context.

description: Il confronto progettuale con il tema delle aree interne fa di solito riferimento a strategie d’intervento che prevedono piani d’azione a lungo termine, con visioni che implicano grandi movimenti finanziari e trasformazioni alla macro-scala. L’assenza di infrastrutture adeguate, servizi sanitari, centri per l’istruzione, rende effettivamente necessaria, per questi territori, una ridefinizione ad ampio raggio degli assetti politici, economici e sociali. Ma in che modo l’architettura, attraverso il progetto, può, anche con interventi puntuali, occupare un ruolo cruciale all’interno di dinamiche di maggiore respiro? Questi luoghi, che hanno in molti casi perso la forza identitaria che un tempo li caratterizzava, hanno bisogno di azioni mirate che si nutrano delle specificità che ciascuno di essi custodisce. Si fa riferimento a tattiche di progetto per indicare modalità di intervento che, rifuggendo da astrazioni, cercano un contatto diretto con il territorio, guardando all’architettura come manifestazione di un vocabolario consolidato e non come cifra espressiva individuale. Parole chiave: condivisione, identità, prossimità

description: L’approccio fornito dalla SNAI nella classificazione del territorio nazionale in base al criterio di perifericità, della distanza cioè a partire dai Centri di offerta dei servizi, fornisce interessanti spunti per ripensare la mobilità di quelle aree a domanda debole che rischiano di subire un sempre più accelerato fenomeno di marginalizzazione. In particolare, viene presentato il caso studio dell’Area Antola-Tigullio (inserita come area prototipale per la Regione Liguria all’interno della Strategia Nazionale) per cui si propone di progettare appositi servizi di trasporto on demand in grado di restituire ai residenti dell’area quell’accessibilità che viene definita nella SNAI come elemento costitutivo della cittadinanza stessa e dunque come occasione di implementare il grado di inclusione sociale. Parole chiave: aree interne, domanda debole, sistemi di trasporto on demand

description: Computational techniques allow insights into chemical processes that are normally experimentally difficult to access (e.g. transition states). Here, we report on the computational modelling of a recently reported supramolecular system that experimentally displays a complex mixture of cooperative, allosteric, homotropic and heterotropic binding behaviour in the interactions of two calcium cations and two chloride anions with a tetratopic ion-pairing host (bis-isophthalamide-crown-6) H. Using DFT, we are able to predict the structural conformations and binding energies of the multi-step thermodynamic binding cycle in both directions for the formation of the quinary 2Ca2+·H·2Cl− complex in both vacuum and solvent environments with several key steps validated against experimental X-ray and binding study data. This study revealed unexpected conformational changes in the free host upon binding two Cl− anions, with a tetra-coordinated (four hydrogen-bonds) 1:1 H·Cl− complex forming before the expected bis(isopthhalimide-Cl−) 1:2 H·2Cl− complex with two hydrogen bonds is formed. The results here show that given the appropriate method (basis set, solvent environment) DFT calculations can both predict and give unique insight into multi-ion host supramolecular interactions like those encountered in ion-pair host–guest studies.

description: A method combining the Lagrange-mesh and the complex Kohn variational methods is developed for computing the $\mathcal{S}$ matrix of a 2$+$1 elastic scattering in the frame of three-body Coulomb systems. Resonance parameters can be obtained from values of the $\mathcal{S}$ matrix at several scattering energies. The method is illustrated with the $S$-wave low-energy scattering of an electron onto hydrogen. The computed phase shifts are at least as accurate as the literature results, and the resonance parameters are more accurate than the best literature results by several orders of magnitude. Both the infinite and finite proton mass cases are considered.

description: I piccoli arcipelaghi italiani, a ben vedere, potrebbero costituire luoghi paradigmatici della “internità” delineata dalla SNAI, ideali per verificare l’operabilità e l’efficacia delle strategie mirate al miglioramento dell’”abitabilità” dei contesti periferici e ultra-periferici del territorio nazionale, tenuto in debito conto il rilevante fattore di contesto costituito dalla numerosità delle piccole isole italiane. La sfida quindi è costruire processi di sviluppo locale fondati sulle risorse materiali e immateriali, valorizzando anche le occasioni eccezionali offerte dai grandi eventi, capaci di trasformare lo straordinario nell’ordinario. Si vuole così cercare di invertire la tendenza all’abbandono progressivo che interessa tanti piccoli arcipelaghi italiani, accompagnandoli in processi di rigenerazione territoriale e valorizzazione del cultural heritage. Parole chiave: isole, marginalità, recupero

description: Come noto, le Aree interne, distanti dai centri che dispensano servizi essenziali, e caratterizzate da un prolungato declino demografico ed economico, rappresentano un prototipo significativo di aree marginalizzate, così come i territori montuosi degli Appennini identificano aree fragili ripetutamente colpite da disastri naturali ed esposte ai fenomeni sismici. Nelle aree colpite dal sisma 2016 si è verificata la parziale sovrapposizione tra i due fenomeni e la necessità di rendere coerenti e sinergiche le politiche promosse per affrontarli. Il contributo analizza i caratteri dei due fenomeni evidenziandone le sinergie, le conflittualità o l’assenza di dialogo, attraverso l’analisi di due aree interne in regione Marche nelle quali il gruppo di ricerca ha svolto il ruolo di soggetto intermedio, ingaggiato nella costruzione di percorsi di ricostruzione post-sisma nei quali emerge la necessità di stabilire utili alleanze con altre progettualità e politiche in atto. Parole chiave: aree interne, ricostruzione post-sisma, disaster risk reduction

description: Urbano e montano non sono più gli estremi territoriali all’interno dei quali si colloca il territorio alpino ma sempre più sono parti che concorrono alla configurazione di un territorio al plurale, nel quale sono tenuti insieme centri e aree marginali che svolgono un nuovo ruolo nel posizionamento e nelle geometrie di questo assemblaggio. In questa direzione, il contributo intende portare alla riflessione quei processi di trasformazione dei territori alpini che scardinano la tradizionale dicotomia centro-periferia e mettere in evidenza possibili modalità di ri-lettura dei territori stessi. Territori che, attraverso configurazioni territoriali innovative, si mostrano in grado di attivare il potenziale latente riconnettendo margini e centro in un quadro di rigenerazione territoriale. Per illustrare il tema proposto il contributo prende in esame contenuti e risultati di una esperienza didattica relativa al tema di rigenerazione nel territorio della media valle di Susa. Parole chiave: aree marginali, sistemi urbano-montani, progetti di rigenerazione territoriale

description: A polystyrene with pendant calix[4]pyrroles was prepared via ‘click reaction’ strategy. First, a poly(styrene-co-chloromethylstyrene) with approximately 12% of chloro groups was prepared by conventional free radical polymerisation. The chloro groups were then converted to azido groups using NaN3 in N,N-dimethylformamide. An alkyne-functionalised calix[4]pyrrole was then coupled to the azido-functionalised polystyrene by click chemistry with high efficiency. The resulting polystyrene with pendant calix[4]pyrroles was used to extract fluoride and chloride anions (as their tetrabutylammonium salts) from their aqueous solutions to organic media.

description: Le difficoltà e le lentezze che caratterizzano l’attuazione della Strategia Nazionale Aree Interne (SNAI) rendono necessarie riflessioni su come perseguirne gli ambiziosi obiettivi. Questo articolo intende contribuire a questo dibattito a partire dagli esiti di un percorso di ricerca nel comune siciliano di Vizzini, facente parte dell’area pilota SNAI del Calatino. Si tratta di una ricerca svolta nell’ambito del progetto “BeeDINI – Vizzini 2030” finanziato da Fondazione con il Sud a una partnership locale per la riattivazione comunitaria di un edificio storico-monumentale. In questo caso, proprio a partire dai limiti oggettivi mostrati dalla SNAI, si sta lavorando parallelamente ad essa, con un focus su come la valorizzazione del patrimonio storico-architettonico sia davvero occasione di sviluppo. La ricerca mostra come, al di fuori delle dinamiche di potere locale che si scatenano fra amministratori costretti a tavolino al lavoro a scala ‘sovracomunale’ e la permanenza dei vecchi modi di pensare a agire sul patrimonio, sia promettente perseguire azioni ispirate a un approccio di ‘innovazione socio-spaziale’, in linea con i principi della SNAI, superando la retorica del ‘ritorno alle glorie del passato’, con un focus sui giovani e affidandosi alle capacità innovative delle eccellenze del terzo settore siciliano. Parole chiave: innovazione sociale, economia coesiva, mappatura di comunità

description: Il progetto di architettura è strumento necessario per la ri-attivazione sociale e culturale dei piccoli paesi, molti dei quali in abbandono cronico: necessario ma non sufficiente. La possibilità che questi piccoli centri e borghi distribuiti in maniera diffusa sull’Appennino centro-meridionale italiano invertano la tendenza all’abbandono dipende principalmente dalle forze endogene delle comunità che questi centri abitano. La recente pandemia da Covid- 19 ha accelerato processi di telelavoro e questo sembra aver aperto nuove inattese opportunità per le più giovani generazioni che hanno la possibilità di lavorare in maniera qualificata e restare ad abitare nei luoghi di origine. Il testo dà conto di sperimentazioni in tre piccole comunità del Molise (Riccia, Jelsi, Gambatesa) inserendo tali recenti sperimentazioni di ricerca progettuale nella scia di riflessioni sulle aree interne che hanno attraversato il ‘900. Parole chiave: comunità, condivisione, territorio

description: La marginalità caratterizza anche l’Appennino settentrionale, tanto da stimolare politiche attive, sostenute da finanziamenti sovralocali, che intervengono per modificarne le condizioni socio-economiche e invertire la tendenza allo spopolamento e all’abbandono. Dopo l’introduzione, che definisce il tema e le strategie d’azione presenti nel dibattito nazionale e internazionale, la prima parte descrive due politiche volte a modificare le condizioni di marginalità e di decremento demografico (il programma europeo Leader e la Strategia nazionale per le aree interne, Snai). Segue una descrizione dell’area studio relativa al territorio collinare e montano di Piacenza e Parma, e la restituzione delle due policy per come sviluppate nell’esperienza locale del Gal del Ducato (Leader) e di Appennino smart (Snai). Riflessioni su temi e direzioni di cambiamento innescate chiudono il contributo. Parole chiave: aree interne, spopolamento, riabitare

description: Il contributo prende spunto dalle attività sviluppate nell’ambito del progetto “Riabitare i Paesi. Strategie Operative per la Valorizzazione e la Resilienza delle Aree Interne” (RI.P.R.O.VA.RE) ed è finalizzato ad una prima valutazione degli impatti a scala locale degli investimenti pubblici di tipo straordinario della programmazione comunitaria e nazionale. Definiti alcuni indicatori quantitativi, in base alla disponibilità di dati alla scala comunale, se ne propone una applicazione nell’ambito territoriale del Matese nella Provincia di Caserta. L’esercizio valutativo intende avviare, dopo una ricostruzione del quadro della progettualità locale, una prima riflessione sugli impatti dei più significativi investimenti pubblici a scala locale, in particolare nelle aree interne, per promuovere più efficaci politiche di sviluppo. A tal proposito, la definizione di indicatori calcolabili alla scala comunale, riferiti ad alcuni degli obiettivi dell’Agenda 2030, potrebbe supportare più efficaci ed efficienti progetti e programmi di sviluppo locale. Parole chiave: aree interne, politica di coesione europea, valutazione di impatto
