Channel changes and invertebrate faunas below Nant-Y-Moch dam, River Rheidol, Wales, UK
No full textRiver impoundment is known to affect the physical, chemical, and biological characteristics of the downstream river, but little is known of the way in which changes of these characteristics interact or the time-scale required to attain a new quasi-equilibrium state. The data presented herein show that channel sedimentation below a tributary confluence, resulting from reduced flow competence and capacity within the regulated mainstream, has produced morphological changes associated with substrate particle-size alteration. Four physical compartments are identified, each representing a different stage of readjustment to the hydrological conditions imposed by the dam. Each stage is shown to have a characteristic fauna. Moreover, the species diversity, composition, and biomass were found to be most different from the natural data during the early stages of readjustment and to approach the natural data more closely as the channel attained a quasi-equilibrium form
THE VALUE OF THE HIGH ASWAN DAM TO THE EGYPTIAN ECONOMY
No full textThe High Aswan Dam converted a variable and uncertain flow of river water into a predictable and controllable flow. We use a computable general equilibrium model of the Egyptian economy to estimate the economic impact of the High Aswan Dam. We compare the 1997 economy as it was to the 1997 economy as it would have been for 72 historical, pre-dam water flows. The steady water flow increased transport productivity, while the seasonal shift in water supply allowed for a shift towards more valuable summer crops. These static effects are worth LE 4.9 billion. Investments in transport and agriculture increased as a consequence. Assuming that Egypt is a small open economy, this is worth another LE 1.1 billion. The risk premium on the reduced variability is estimated to be LE 1.1 billion for a modest risk aversion, and perhaps LE 4.4 billion for a high risk aversion. The total gain of LE 7.1 billion equals 2.7% of GDP.Egypt, High Aswan Dam, computable general equilibrium model, risk premium, water supply
Whistleblowing in Italy : rights and protections for employees
No full textThis paper examines the whistleblowing in the Italian legal system. In the lack ofproper rules on such a phenomenon (quite uncommon in the Italian social reality, also due to cultural reasons) except for the civil servants, the paper goes on analysing, on the one hand, the provision applicable to the civil servants (i.e. art. 54 of the Legislative Decree no. 165/2001), and on the other hand, the instruments provided for by the Italian legal system as general principles, which can be applied by the judge in order to protect the whistleblowers in the private sector (in particular the rules against retaliatory and discriminatory acts and mobbing). The Author stresses that the recalled protection, although effective (also after the so-called 'Monti's reform', id est the Law No. 92/2012), could be not sufficient both because of the allocation of the burden of proof, and because it is applicable to the employees and only partially (as the Author explains in the last paragraph) to the whistleblowing in the context of self-employment. Then the paper analyses the balancing performed by the Italian caselaw between the right to information and the right of criticism, on one side, and the right to secrecy set forth by law in respect of business facts and information, and the personality rights granted to the employer by the Constitution,on the other side. Finally the paper deals with the applicable procedures, introduced by disciplinary codes, also according to the Legislative Decree No. 231/2001, and the problems related to internal reporting systems, in particular the balancing between the needs for the whistleblower's protection and the positive law in the matter of protection of the privacy of the person to whom the complaint relates according to the Legislative Decree No. 196/2003
L'obbligo di ripescaggio nel licenziamento per giustificato motivo oggettivo di tipo economico alla luce del Jobs Act
No full textIl contributo si interroga sul ruolo che, in seguito alle ultime riforme del lavoro, ha assunto il cd. ripescaggio all’interno del licenziamento per giustificato motivo oggettivo di tipo economico. Nella prima parte del saggio, l’esame dei più recenti orientamenti della giurisprudenza, in particolare di quella sull’onere della prova, conduce alla conclusione che il ripescaggio è parte integrante del gmo posto dall’art. 3, l. 604/1966 inteso quale limite interno (o causale) dell’atto di licenziamento, in quanto costituisce il nesso causale negativofra riorganizzazione disposta dal datore e mansioni del lavoratore. Il significato così assunto dal gmo, pur costituendo certo un limite “minimale” dell’atto di licenziamento, risulta comunque conforme ai principi costituzionali, eurounitari e internazionali, secondo l’interpretazione consolidatasi fino ad oggi. La seconda parte del lavoro analizza come la nuova disciplina dello ius variandi (art. 2103 c.c. come modificato dall’art. 3, d.lgs. 81/2015) impatta sulla struttura e sull’ampiezza del ripescaggio. Partendo dal presupposto che il nuovo testo dell’art. 2103 c.c. amplia il debito del lavoratore, includendovi tutte le mansioni appartenenti al medesimo livello di inquadramento rispetto alle mansioni di assunzione (1 co.) e le mansioni del livello immediatamente inferiore (co. 2) – l’A. giunge alla conclusione che il ripescaggio costituisce oggi oggetto di un vero e proprio onere e si estende a tutte le mansioni che integrano il debito di lavoro. Il datore di lavoro infatti ha l’onere, a pena di ingiustificatezza del licenziamento, di cooperare all’adempimento del lavoratore e, dunque, di adibire il lavoratore, nell’esercizio del proprio potere direttivo, ad una delle mansioni dovute, dello stesso livello o del livello immediatamente inferiore rispetto alle mansioni di assunzione. Il mancato rispetto del ripescaggio, così trasformato dall’art. 2103 nuovo testo c.c., è poi corredato da un successivo ed autonomo obbligo di formazione, che grava sul datore di lavoro. Infine, a corollario del ragionamento, l’A. ritiene che il “fatto giuridico” la cui “manifesta insussistenza” dà luogo, ai sensi dell’art. 18, co. 5, St. lav. alla tutela reintegratoria attenuata includa anche il mancato rispetto del ripescaggio, nell’accezione risultante dal combinato disposto dell’art. 3 l. 604/1966 e art. 2103 nuovo testo c.cTHE DUTY OF «REPECHAGE» IN THE DISMISSAL FOR OBJECTIVE ECONOMIC REASONS IN THE LIGHT OF THE JOBS ACT REFORM.
The essay focuses on the role of repêchage in the definition of the dismissal for objective economic reasons after the recent Italian labour law reforms. In the first part of the essay, moving from the analysis of the case-law, especially the one concerning the burden of proof, the author highlights that repêchage is part of the definition of dismissal for objective economic reasons as provided for by Art. 3 Law no. 604/1966, as it represents the causal link between the reorganization of the firm and the workers’ skills. This is in line with both the Italian Constitution and the principles at supranational and international level. In the second part of the essay, the author analyses how the new text of Art. no. 2103 c.c. (as reformed by delegated decree no. 81/2015) affects the duty of repêchage. According to the author, the new art. 2103, broadening the range of tasks the employee can be assigned to in the workplace, has also broadened the notion of repêchage. In her conclusive remarks, she argues that an employer’s failure to fulfil the duty of repêchage, should lead to the reinstatement of the employee under art. 18, co. 5, St. la
Novel antibiotics from DNA adenine methyltransferase inhibitors
No full textThe re-emergence of plague as a world-wide health concern and the potential risk posed by bioterrorism has led to an increased interest in available treatments for the disease. The bacterial DNA adenine-N6 methyltransferase, Dam, is involved in the regulation of a range of pathogenic bacteria and has been validated as a target for the development of antimicrobial agents with activity against Yersinia pestis, the causative agent of plague. The lack of a functionally similar enzyme in mammals suggests that highly selective Dam inhibitors could be developed. A coupled, real-time break light Dam activity assay has been optimised for HTS, and assays for the validation and characterisation of screening hits have also been developed. Screening of random and in silico enriched compound libraries, and the subsequent application of counter-screening and hit confirmation assays, resulted in the identification of a single viable lead, (4-(N-(2-hydroxyethyl)sulfamoyl)phenyl) stibonic acid (13776). Screening of compounds analogous to 13776 identified a series of arylstibonic acids with activity against Dam. Kinetic characterisation of the most potent arylstibonic acid, 4-stibonobenzenesulfonic acid (13746), revealed a DNA-competitive mode of action, and a Ki of 6.46 ± 0.07 nM. However, selectivity assays have revealed a potentially non-specific mode of action for the stibonic acids, which have shown activity against a range of DNA and protein binding enzymes. Yersinia cell culture experiments have shown a single compound, (3-((2-hydroxyethyl)carbamoyl)phenyl)stibonic acid (13782), to be capable of penetrating Yersinia cells and partially inhibiting methylation, and mRNA profiling experiments have shown 13782 to induce a statistically significant change in several genes involved in the pathogenicity of Y. pestis. Attempts at resynthesising 13782 have proved challenging, with only a fraction of the activity of the original sample reproduced. HPLC analysis of the original and resynthesised samples has shown the former to comprise two components, with only one present in both samples. The in vitro evaluation of a series of bisubstrate analogues designed to mimic both the methyl donor S-adenosylmethionine (AdoMet), and the methylation target (adenine) has shown that substitution of the AdoMet sulfur for nitrogen results in a significant but not total loss of activity. Furthermore, the addition of a bicyclic heteroaromatic adenine analogue mimic to this scaffold led to an increase in potency and selectivity for Dam over the human cytosine methyltransferase DNMT1 but a reduction in selectivity for Dam over the restriction enzyme DpnI. These results suggest that a selective and potent Dam inhibitor can be obtained by carefully modifying both components of the bisubstrate analogue inhibitor

Il licenziamento nullo perchè discriminatorio, intimato in violazione di disposizioni di legge o in forma orale
No full textL’articolo esamina le varie forme di licenziamento nulle ai sensi del Jobs Act (licenziamento discriminatorio; licenziamento per ritorsione; licenziamento per violazione di legge; licenziamento per disabilità fisica e psichica; licenziamento per mancato superamento del periodo di comporto; licenziamento intimato in forma orale) sia al fine di definire i confini delle varie figure – anche rispetto alla nozione di licenziamento ingiustificato – sia per dipanare la questione delle tutele applicabili. Tale secondo problema è rilevante perché il Jobs Act a fronte delle varie ipotesi di licenziamento nullo non sempre esplicita la forma di tutela applicabile. Nel contributo l’A. sostiene l’idea che – benchè sia indubbio che in via generale il Jobs Act ha elevato a regola la tutela indennitaria e ha relegato ad eccezione la tutela reintegratoria – tuttavia con specifico riferimento all’area del licenziamento nullo esso ha riconfermato la centralità della tutela reintegratoria in considerazione dei particolari interessi della persona del lavoratore che entrano in gioco. Ne deriva che le varie ipotesi di licenziamento nullo – anche ove la legge non contempli una previsione specifica; sono soggette alla tutela reintegratoria ex art. 18 St.lav. o alla tutela reintegratoria “di diritto comune”.The article examines the various forms of dismissal void under the Jobs Act (discriminatory dismissal, dismissal for retaliation, dismissal for violation of the law, dismissal for physical and mental disability, dismissal for failure to exceed the period of compensation, dismissal announced orally) in order to define the boundaries of the various figures; also with respect to the notion of unfair dismissal; and to solve the problem of the applicable protections. This second problem is relevant because the Jobs Act in the face of the various hypotheses of invalid dismissal does not always explicitly the form of protection applicable. In the contribution, the Author supports the idea that; although it is undoubted that in general the Jobs Act has elevated to rule the indemnity protection and has relegated to exception the reinstatement protection; however, with specific reference to the area of invalid dismissal it has reconfirmed the centrality of the reinstatement protection in view of the particular interests of the person of the worker who come into play. It follows that the various hypotheses of invalid dismissal; even where the law does not provide for a specific provision; are subject to the reintegration protection pursuant to art. 18 of Statuto dei Lavoratori or to the reintegration protection "under common law

Management and Simulation of the Latian Multi-purpose Reservoir Dam and Its Performance Evaluation Based on the Operation Policy on Daily Time Scale
No full textIntroductionDevelopment of reservoirs helps to meet food and energy needs by supplying water for agriculture and hydropower plants. Efficient management of water resources is important and vital to overcome the problems of water leakage and meet agricultural, industrial and drinking needs. Each of these requirements creates limitations in the way the reservoir is operated, which requires accurate information on the changes in the reservoir storage and other influential components during the operation period. In order to manage and plan water resources at country scale, using reservoir simulation models as a suitable tool in simulating processes related to dams, such as the operation of water reservoirs, will be very effective. Reservoir simulation models such as the HEC-ResSim model provide the opportunity to simulate the natural and hydrological processes related to the water resources system and the relationships between the supply and demand sectors by implementing a schematic structure of a real reservoir. Two scenarios of water savings of 20 and 30 percent were used in the current investigation. Additionally, using this method, the objectives of water resource management can be assessed.Materials and MethodsIn the present study, the use of the Latian reservoir in real conditions was simulated using the HEC-ResSim model. The simulation was carried out according to the river's inflow from 1968 to 2018, downstream water needs, energy production capacity by turbines, physical characteristics and reservoir building. The implementation of the HEC-ResSim model is summarized in three steps. The Watershed Setup module is used to introduce the general outline of the watershed. In this module, the shape and geographical location of the basin and related elements such as rivers, reservoirs, hydrometric stations and other projects in it should be specified. The Reservoir Network module is used to introduce the desired reservoir network and to enter the physical characteristics and how to use them. The Simulation module is designed to introduce the simulation period and display the model outputs. In this module, the simulation time and period and the operation pattern should be determined.Results and DiscussionAccording to the results obtained from the reservoir simulation model, the average storage capacity of Latian dam for the simulation period was estimated to be 41 million cubic meters, which shows a significant drop of 49% compared to the normal level (83 million cubic meters). Additionally, for the same period, it was estimated that the average discharge was equivalent to 5.4 cubic meters per second and the average inflow to the reservoir of the Latian dam was equal to 5.7 cubic meters per second. This is in contrast to the period's average demand, which for the area downstream of the Latian Dam is 12.1 cubic meters. The findings indicate that the reservoir of the dam frequently, and particularly at the conclusion of the simulation period, is unable to satisfy the needs of the downstream. Additionally, according to the findings of the current study, the Latian dam power plant's (Kalan) average annual hydro-electric energy production was projected to be 68,000 MWh, and the results show that in accordance with the policy of operating the Latian dam in the majority ofthe years, the Kalan power plant is able to supply the electricity required in the study area. According to the results, the average reservoir volume of Latian dam for the entire period in the first and second scenario was estimated to be 49 and 63 million cubic meters, respectively. Also, by applying the first and second water saving scenarios, the Latian dam reservoir will be able to generate 66,000 and 63,000 MWh of energy annually.ConclusionIn this study, the functioning and operation of the Latian dam reservoir was used by applying the Hec-ResSim reservoir simulation model. After entering data such as the elevation and length of the dam, surface-volume-elevation curve, evaporation from the surface of the reservoir, elevation and uncontrolled outlet coefficient, dam storage areas, rule curve, were simulated by the model. In the present study, the values of inactive volume and conservation volume of Latian Dam were estimated as 28 and 83 million cubic meters, respectively. The average water release of Latian dam for the first and second 25 years of operation was equal to 6.1 and 3.7 cubic meters per second, respectively, which met 50 and 32% of the downstream demand on average. The results indicate that the success rate of Latian dam in supplying drinking, industry and downstream environment for the period of operation is 42%. Also, 16 years out of 50 years of operation, Kalan hydropower plant has fully met 100% of the needs. On average, the large power plant is able to provide 80% of the energy needs of the study area for the entire simulation period
