description: "What we’ve decided to do as our format for this presentation is: we have a number of scenarios that people have suggested of things that have actually come across their desks in the course of doing what they do. And we thought we would just go through these quickly and talk about the issues that they raise—a sort of issue-spotting exercise—and try to offer some guidance about maybe how to deal with those issues as well. We’re going to start by talking about a number of things other than copyright. We’ve had a lot of discussion today about copyright and we may get to some more copyright here if we have time, but I’m going to start by talking about a number of noncopyright issues in the areas of privacy, defamation, things like that that very often come up in the context both of sound and audiovisual materials, but also in the case of text and photographs and so on."

description: A need was identified to address the planning process for the development of the West Campus Lands of the University of Calgary due to the sensitive nature and large-scale development of the site within the surrounding established communities. Through key informant interviews, the main issues and concerns regarding the development of the West Campus Lands were identified. A review of public policy documents provided the policy direction to resolve them. Common themes were divided into the categories of land uses, transportation, linkages, environmental issues and relations in order to analyze how existing plans for the West Campus Lands addressed multiple stakeholder interests. Key unresolved issues were identified through the analysis and used as a basis to provide recommendations and develop a conceptual land use plan to guide future development of the West Campus Lands. The recommendations and conceptual land use plan are directed towards planners for the West Campus Lands including officials from the University, the Calgary Health Region, the City of Calgary and the surrounding communities.

description: We study the dynamics of continuous-time quantum walks (CTQW) on networks with highly degenerate eigenvalue spectra of the corresponding connectivity matrices. In particular, we consider the two cases of a star graph and of a complete graph, both having one highly degenerate eigenvalue, while displaying different topologies. While the CTQW spreading over the network - in terms of the average probability to return or to stay at an initially excited node - is in both cases very slow, also when compared to the corresponding classical continuous-time random walk (CTRW), we show how the spreading is enhanced by randomly adding bonds to the star graph or removing bonds from the complete graph. Then, the spreading of the excitations may become very fast, even outperforming the corresponding CTRW. Our numerical results suggest that the maximal spreading is reached halfway between the star graph and the complete graph. We further show how this disorder-enhanced spreading is related to the networks' eigenvalues.

description: By its very nature, advertising is a prominent feature of economic life. Advertising reaches consumers through their TV sets, radios, newspapers, magazines, mailboxes, computers and more. Not surprisingly, the associated advertising expenditures can be huge. For example, Advertising Age (2005) reports that, in 2003 in the U.S., General Motors spent $3.43 billion to advertise its cars and trucks; Procter and Gamble devoted $3.32 billion to the advertisement of its detergents and cosmetics; and Pfizer incurred a $2.84 billion dollar advertising expense for its drugs. Advertising is big business indeed.
Joint liability versus individual liability in credit contracts
Creators: name: Madajewicz, Malgosia
Publisher: name: Columbia University
Year: 2004
Subjects: Economics

description: I compare welfare generated by a credit contract with individual liability and a contract with joint liability. The problem is credit rationing caused by limited liability and unobservable investment decisions. Joint liability induces borrowers to monitor each other, however the lender can also monitor. I show that wealthier borrowers may prefer riskier investments when liability is joint, which causes the lender to offer them smaller loans than he would if liability were individual, even if he cannot monitor the individual-liability loan. Therefore, wealthier borrowers prefer individual-liability loans. The result may explain why small businesses grow larger when funded with individual rather than with joint-liability loans. Poorer borrowers may prefer joint-liability loans, because borrowers monitor more efficiently, even when their monitoring technology is the same as the lender's, making joint-liability loans cheaper.

description: We study the transport of information between two complex networks with similar properties. Both networks generate non-Poisson renewal fluctuations with a power-law spectrum 1/f^(3-μ), the case μ= 2 corresponding to ideal 1/f-noise. We denote by μ_S and μ_P the power-law indexes of the network "system" of interest S and the perturbing network P respectively. By adopting a generalized fluctuation-dissipation theorem (FDT) we show that the ideal condition of 1/f-noise for both networks corresponds to maximal information transport. We prove that to make the network S respond when μ_S < 2 we have to set the condition μ_P < 2. In the latter case, if μ_P < μ_S, the system S inherits the relaxation properties of the perturbing network. In the case where μ_P > 2, no response and no information transmission occurs in the long-time limit. We consider two possible generalizations of the fluctuation-dissipation theorem and show that both lead to maximal information transport in the condition of 1/f-noise.

Outward FDI from Colombia and its policy context

Subjects: Finance

description: Outward foreign direct investment (OFDI) from Colombia has increased considerably in the past decade, with its stock growing from US$ 3 billion in 2000 to US$ 23 billion in 2010. This growth reflects the internationalization of the Colombian economy following policy reforms and economic liberalization in the 1990s. The 2000s were characterized by enhanced national security and reforms to the investment framework that have attracted unprecedented levels of inward FDI and facilitated the growth of small and medium-sized enterprises (SMEs). A considerable rise in domestic mergers and acquisitions (M&As) in the past decade has contributed to the development of Colombian multinational enterprises (MNEs) and to increased OFDI from Colombia. In 2010, outflows showed a twenty-fold increase from their value in 2000, including an increase in OFDI to export markets, helped by greater government support for OFDI, for example by the conclusion of more international investment agreements. The rise of Colombian MNEs, or "translatinas" (i.e. Latin American MNEs whose OFDI is primarily within Latin America), reflects Colombia's nascent structural transformation into a knowledge-based economy.
Optimal Exchange Rate Policy Under Collateral Constraints and Wage Rigidity
Creators: name: Ottonello, Pablo
Publisher: name: Columbia University
Year: 2013
Subjects: Economics

description: Existing literature on small open economies has studied separately two opposite effects of currency depreciation during crises: in the presence of nominal wage rigidity, exchange rate depreciation reduces unemployment; in the presence of collateral constraints that link external debt to the value of income, exchange rate depreciation tightens the collateral constraint and leads to higher consumption adjustment. This paper shows that in a model that includes both frictions, exchange rate policy faces a “credit access - unemployment trade-off," i.e., a trade-off between reducing involuntary unemployment and relaxing the external credit limit. A quantitative study of this model shows that during financial crisis episodes, optimal policy features large nominal and real exchange rate depreciation. This is because, while containing real exchange rate depreciation can have welfare gains related to second moments (lower consumption volatility) its costs are related to first-moments (higher average unemployment rate). The optimal policy implies a lower currency depreciation than that necessary to achieve full employment, which is consistent with “managed-floating" exchange rate policy, typically observed during financial crises in emerging economies. Sudden Stops (or large current account adjustments) are part of the endogenous response under the optimal exchange rate policy to large negative shocks.
Double-Edge-Triggered Flip-Flops

description: A conventional positive-edge-triggered flip-flop (FF) senses and responds to the control input or inputs at the time the clock input is changing from 0 to 1. It does not respond at all to changes in the opposite direction. Negative-edge-triggered FF's behave in a complementary manner. Thus, these FF's can respond at most once per clock pulse cycle. It is proposed that double-edge-triggered (DET) FF's, responding to both edges of the clock pulse, would have advantages with respect to speed and energy dissipation.
Deposit insurance, institutions and bank interest rates

description: Many recent institutional reforms of the financial system have relied on the introduction of an explicit scheme of Deposit Insurance. This instrument aims at two main targets, contributing to systemic stability and protecting depositors. However it may also affect the interest rate spread in the banking system, which can be viewed as an indicator of market power in this financial segment. This paper provides an empirical investigation of the effect of deposit insurance and other institutional and economic variables on bank interest rates across countries. We find that deposit insurance increases the lending borrowing spread in banking. The main effect seems to arise not from the deposit side though, but from an increase in the lending rate. We interpret this result as evidence of the presence of moral hazard problems related to this instrument. We also find that higher quality of institutions is associated with lower spreads, thus contributing to eroding sources of market power in the banking sector.
Optimal inflation targeting under alternative fiscal regimes

Publisher: name: Columbia University
Year: 2005
Subjects: Economics

description: Flexible inflation targeting has been advocated as a practical approach to the implementation of an optimal state-contingent monetary policy, but theoretical expositions reaching this conclusion have typically abstracted from the fiscal consequences of monetary policy. Here we extend the standard theory by considering the character of optimal monetary policy under a variety of assumptions about the fiscal regime, with the standard analysis appearing only as a special case in which non-distorting sources of government revenue exist, and fiscal policy can be relied upon to adjust so as to ensure intertemporal government solvency. Alternative cases treated in this paper assume that there exist only distorting sources of government revenue; that it may not be possible for tax rates to adjust in response to economic disturbances, except with delay; or even that fiscal policy is purely exogenous, so that the central bank cannot rely upon fiscal policy to adjust in order to maintain intertemporal solvency (a case emphasized in the critique of inflation targeting by Sims, 2005). We find that the fiscal policy regime has important consequences for the optimal conduct of monetary policy, but that a suitably modifed form of inflation targeting will still represent a useful approach to the implementation of optimal policy. We derive an optimal targeting rule for monetary policy that applies to all of the fiscal regimes considered in this paper, and show that it involves commitment to an explicit target for an output-gap adjusted price level. The optimal policy will allow temporary departures from the long-run target rate of growth in the gap-adjusted price level in response to disturbances that affect the government's budget, but it will also involve a commitment to rapidly restore the projected growth rate of this variable to its normal level following such disturbances, so that medium-term inflation expectations should remain firmly anchored despite the occurrence of fiscal shocks.

description: Based on the recently proposed Roy-Steiner equations for pion-nucleon scattering, we derive a system of coupled integral equations for the pi pi --> N-bar N and K-bar K --> N-bar N S-waves. These equations take the form of a two-channel Muskhelishvili-Omnes problem, whose solution in the presence of a finite matching point is discussed. We use these results to update the dispersive analysis of the scalar form factor of the nucleon fully including K-bar K intermediate states. In particular, we determine the correction Delta_sigma=sigma(2M_pi^2)-sigma_{pi N}, which is needed for the extraction of the pion-nucleon sigma term from pi N scattering, as a function of pion-nucleon subthreshold parameters and the pi N coupling constant.

Exploring factors associated with readiness to change during the acquisition of motor abilities in young children with cerebral palsy
Creators: name: Sauve, Karen Ann
Publisher: name: University of British Columbia
Year: 2011

description: Purpose: The timing of physiotherapy intervention for optimal motor outcomes in children with cerebral palsy (CP) remains unknown. Dynamic Systems Theory (DST) suggests this timing is during transition periods when new motor behaviour is emerging; transition periods are identified by increased variability in motor performance. Additionally, factors within the child and environment are thought to influence motor acquisition. The aim of this study was to explore the relationships between these factors and motor acquisition in young children with CP. Specifically the following were examined: 1. a) Variability in motor abilities during a preceding time interval, b) Variability in motor performance during a preceding time interval, 2. Child factors, and 3. Environmental factors. Methods: For this case series, the sample comprised five children with CP, aged three to five years, and classified in levels I to III of the Gross Motor Function Classification System. Each child’s gross motor abilities and performance were assessed during ten home visits using the Gross Motor Function Measure and the Quality FM respectively. Mastery motivation and engagement in daily life were assessed through questionnaires. Environmental factors were described using field notes at each home visit. Results: No associations were found between a) variability in motor abilities or b) variability in motor performance and subsequent motor acquisition in each child individually nor when data were pooled across children. Mastery motivation was inversely associated with motor change (rs=-0.90, p=0.04) for the pooled data set. Child engagement and GMFM scores were not related nor were there trends in field note data with GMFM change scores. Conclusions: Although this study failed to identify associations between the factors explored, the results were likely impacted by the inability of the measurement tools used to capture subtle changes in motor behaviour in this sample. Further investigation is warranted using a larger, diverse sample of children with CP using nonlinear tools designed to measure movement variability. Greater understanding of the implications of variability on the emergence of motor abilities in this population could offer critical insight into how children with CP acquire motor abilities and select optimal motor strategies under task constraints.

description: In laser-plasma experiments, we observed that ion acceleration from the Coulomb explosion of the plasma channel bored by the laser, is prevented when multiple plasma instabilities such as filamentation and hosing, and nonlinear coherent structures (vortices/post-solitons) appear in the wake of an ultrashort laser pulse. The tailoring of the longitudinal plasma density ramp allows us to control the onset of these insabilities. We deduced that the laser pulse is depleted into these structures in our conditions, when a plasma at about 10% of the critical density exhibits a gradient on the order of 250 μm (gaussian fit), thus hindering the acceleration. A promising experimental setup with a long pulse is demonstrated enabling the excitation of an isolated coherent structure for polarimetric measurements and, in further perspectives, parametric studies of ion plasma acceleration efficiency.

description: We study the electronic transport properties of a dual-gated bilayer graphene nanodevice via first principles calculations. We investigate the electric current as a function of gate length and temperature. Under the action of an external electrical field we show that even for gate lengths up 100 Ang., a non zero current is exhibited. The results can be explained by the presence of a tunneling regime due the remanescent states in the gap. We also discuss the conditions to reach the charge neutrality point in a system free of defects and extrinsic carrier doping.

description: Background: Common post-abdominal surgery problems include incisional hernia. Surgery has poor results, with suture repair recurrence rates ranging from 5% to 63%, depending on the procedure. Mesh implantation works better. The Component Separation Technique is used for treating big hernias. This surgery relaxes the abdominal wall by translating muscle layers without affecting innervation or blood flow, with or without mesh. This handles 25–30 cm waistline issues. Materials and Methods: The research included 10 patients with 10 patients with "Large Incisional Hernia" with a defect size >5 cm at its greatest width or with a surface area >50 cm2 treated with Component Separation. Three months after the operation, the clinical result was assessed in terms of recurrence and other local complications. Results: In this study of 10 patients, body mass index (BMI) distribution showcased a majority (80%) falling within 25-30 kg/m², emphasizing diverse BMI profiles. Hernia size analysis revealed 8-10 cm hernias as the largest segment (50%), followed by 6-8 cm hernias (40%). Smaller 5-6 cm hernias constituted 10%, and larger >12 cm hernias were identified in 10% of patients. These findings underscore the significance of considering varied BMI levels and hernia sizes in surgical interventions, contributing to study population diversity. Conclusion: Patients with big hernias have a fast, simple, and safe choice in component separation technique.
Heat transport by turbulent Rayleigh-Bénard convection for $\Pra\ \simeq 0.8$ and $4\times 10^{11} \alt \Ra\ \alt 2\times10^{14}$: Ultimate-state transition for aspect ratio $Γ= 1.00$

description: We report experimental results for heat-transport measurements by turbulent Rayleigh-Bénard convection in a cylindrical sample of aspect ratio $Γ\equiv D/L = 1.00$ ($D = 1.12$ m is the diameter and $L = 1.12$ m the height). They are for the Rayleigh-number range $4\times10^{11} \alt \Ra \alt 2\times10^{14}$ and for Prandtl numbers \Pra\ between 0.79 and 0.86. For $\Ra < \Ra^*_1 \simeq 2\times 10^{13}$ we find $\Nu = N_0 \Ra^{γ_{eff}}$ with $γ_{eff} = 0.321 \pm 0.002$ and $N_0 = 0.0776$, consistent with classical turbulent Rayleigh-Bénard convection in a system with laminar boundary layers below the top and above the bottom plate and with the prediction of Grossmann and Lohse. For $\Ra > \Ra_1^*$ the data rise above the classical-state power-law and show greater scatter. In analogy to similar behavior observed for $Γ= 0.50$, we interpret this observation as the onset of the transition to the ultimate state. Within our resolution this onset occurs at nearly the same value of $\Ra_1^*$ as it does for $Γ= 0.50$. This differs from an earlier estimate by Roche {\it et al.} which yielded a transition at $\Ra_U \simeq 1.3\times 10^{11} Γ^{-2.5\pm 0.5}$. A $Γ$-independent $\Ra^*_1$ would suggest that the boundary-layer shear transition is induced by fluctuations on a scale less than the sample dimensions rather than by a global $Γ$-dependent flow mode. Within the resolution of the measurements the heat transport above $\Ra_1^*$ is equal for the two $Γ$ values, suggesting a universal aspect of the ultimate-state transition and properties. The enhanced scatter of \Nu\ in the transition region, which exceeds the experimental resolution, indicates an intrinsic irreproducibility of the state of the system.

Optimal Monetary Stabilization Policy
Creators: name: Woodford, Michael
Publisher: name: Columbia University
Year: 2010
Subjects: Economics

description: This chapter reviews the theory of optimal monetary stabilization policy in New Keynesian models, with particular emphasis on developments since the treatment of this topic in Woodford (2003). The primary emphasis of the chapter is on methods of analysis that are useful in this area, rather than on final conclusions about the ideal conduct of policy (that are obviously model-dependent, and hence dependent on the stand that one might take on many issues that remain controversial), and on general themes that have been found to be important under a range of possible model specifications. With regard to methodology, some of the central themes of this review will be the application of the method of Ramsey policy analysis to the problem of the optimal conduct of monetary policy, and the connection that can be established between utility maximization and linear-quadratic policy problems of the sort often considered in the central banking literature. With regard to the structure of a desirable decision framework for monetary policy deliberations, some of the central themes will be the importance of commitment for a superior stabilization outcome, and more generally, the importance of advance signals about the future conduct of policy; the advantages of history-dependent policies over purely forward-looking approaches; and the usefulness of a target criterion as a way of characterizing a central bank's policy commitment.

description: This study is intended to analyze instructors’ performance in teaching learning-process vis-a-vis academic performance of students from gender perspectives. To achieve these objectives, both primary and secondary data were collected. The primary data were obtained using questionnaire designed to assess instructors’ performance in teaching learning process. Moreover, focus group discussion was conducted with students from all departments incorporating both male and female representatives. Stratified random sampling technique was used with 15% of students in the College of Business and Economics taken as respondents. Nearly 50% of instructors were randomly taken to be assessed by instructors. Moreover, secondary data were obtained from students’ academic report of 2011/12 in the first semester. Qualitative and quantitative survey was used as a design of the research. Statistical tests have been made using chi-square and t- test employing SPSS as a tool. It was found that the academic performance of students is relatively poor in aggregate and male students performed better than their female counterparts. The performance difference between male and female students was tested to be statistically significant. The teaching learning performance of instructors is rated to be very high (88.6%) and the response of male and female students about instructors’ performance is not significantly different.

description: The NONÂ·VON machine (portions of which are presently under construction in the Department of Computer Science at Columbia, in cooperation with the Knowledge Base Management Systems Project at Stanford) was designed to apply computational parallelism on a rather massive scale to a large share or the information processing functions now performed by digital computers. The NONÂ·VON architecture comprises a tree-structured Primary Processing Subsystem (PPS), which we are implementing using custom nMOS VLSI chips, and a Secondary Processing Subsystem (SPS) incorporating modified highly intelligent disk drives. NON-VON should permit particularly dramatic performance improvements in very large scale data manipulation tasks, including relational database operations and external sorting. This paper includes a brief overview of the NON-VON project and a more detailed discussion of the structure and function or the PPS unit and its constituent processing elements.

description: The overall objectives of dairy technology transfer project were to demonstrate the improved dairy technologies and strengthen gender involvement in dairy production that enhances the income sources of low income women around Ambo town. For demonstration purpose, low income women were selected for the project and training was given by different expertise on the improved dairy technologies and dairy products handling, processing and marketing. Along with pregnant Friesian-Horro crossbred heifers; improved forages and health services were given as full dairy technology package. Credit service was arranged with Eshet Microfinance Institute. Half of the cost was subsidized by Ambo University and only half of the cost of heifer (2000.00 Birr) was covered by participant women. The average milk yield of Friesian-Horro crossbred cow under farmers’ management was 9.3 liter/day. Women have benefited from the crossbred dairy cows by generating income from selling of milk and milk products and male calves obtained from crossbred cows. An appreciable awareness about improved forage utilization has created. The improved dairy technology has highly accepted and appreciated by women. Unavailability of improved dairy stock, inadequate AI service, shortage of feeds and inadequate health services were reported as the main constraints hindering dairy productivity in the area which should require immediate intervention.

description: An experiment was conducted with the aim of developing a protocol for the in vitro propagation of cactus pear from in vitro derived areole explants. The protocol involves subsequent in vitro morphogenesis and rooting of the in vitro proliferated shoots. For the shoot proliferation stage, explants each with 1 to 2 areoles were cultured on Murashige and Skoog medium (MS) supplemented with benzyladenine (BA) and kinetin (Kin) each with concentrations of 0, 0.5, 1.0, 2.0 and 4 mg/l and two combinations (0.5 mg/l BA + 4.0 mg/l Kin and 0.5 mg/l Kin + 4.0 mg/l BA). Analysis of the results indicated that there was no significant difference among the treatments used in terms of percentage of bud formation. Kinetin at 2.0, 1.0 and 0.5 mg/l were the best for days to shoot emergence. The highest bud numbers (95.75 buds per explant) were achieved on medium supplemented with Kin at 1.0 and 2.0 mg/l. Culturing the explants on MS medium amended with Kin at 1.0 mg/l concentration significantly augmented the shootlet proliferation rates to 29.5-fold higher than on MS-free medium. The best result for shoot length (4.7 cm) was obtained from medium with 0.5 mg/l Kin. Similarly, Kin at 0.5, 1.0 mg/l and BA at 2.0 mg/l yielded maximum plant mass production (shoot fresh and dry weight). Elongated shoot cuttings were placed on the medium (0, 0.25, 0.5, 1.0 and 1.5 mg/l) of naphthalene acetic acid (NAA) and indole-3-butyric acid (IBA) and (0.25 mg/l IBA + 1.5 mg/l NAA and 1.5 mg/l IBA + 0.25 mg/l NAA) for in vitro root induction. Hundred percent rooting was achieved on all of the treatments tested in two weeks of culture except the PGR free medium. The most efficient growth treatment for the longest root length (10.75 cm), maximum root fresh weight (1.88 gm) and root dry weight (0.41 gm) was IBA at 1.5 mg/l. However, there was no significance difference between IBA at 1.0 mg/l and IBA at 1.5 mg/l regarding to root length per explant. The best result for root number (10.0 roots per explant) was obtained from medium supplemented with 1.5 mg/l NAA. In conclusion, it is beneficial to use the in vitro protocol developed in this study for mass micropropagation and circumvent the challenges of conventional in vivo multiplication of cactus pear.

Playing with possibilities : drama in the elementary core French classroom
Creators: name: Ziltener, Eva

description: French as a Second Language (core French) is not often a popular subject among Canadian elementary and high school students. Negative attitudes and low motivation for learning French contribute to attrition at the high school level. In this thesis, an alternative teaching approach is applied to the core French context. This action research study investigates the outcomes of using a drama-based approach to instruct core French to elementary school students. Ten students received core French instruction twice a week over a six-week period. They worked together with a teacher/researcher using drama strategies and improvisational activities to practice and improve their French language and literacy skills. The use of drama strategies proved motivational for the students who participated with enthusiasm and expressed a desire to continue learning French through drama strategies. The use of improvisational activities encouraged students to build an understanding of vocabulary and syntax and reduced their fear of making mistakes in the target language. It also increased self-confidence and motivation for continuing to learn and use French. The action research approach combined with the use of drama strategies allowed the students a greater degree of autonomy – their input and feedback was constantly requested and was used to develop content and lesson plans. This engagement in their own learning contributed to improved student attitudes towards attending French class. Overall students expressed enthusiasm for learning French actively, without having to sit at desks or repeat after the teacher throughout the lesson. Ways of implementing this teaching approach in regular classrooms need to be the subject of future research.

description: The study was undertaken in Ada’a district of Oromia state, Ethiopia to know the constraints of farmers in adopting improved dairy husbandry practices. The study was conducted in eight purposively selected peasant associations/kebeles of the district from which thirty dairy farmers were selected randomly. A total of two hundred forty respondents were selected and personally interviewed through pre-tested questionnaires. The constraints of farmers in adopting improved dairy husbandry practices were operationalized as the reason/s for non-adoption and discontinuation of the practices after adoption. On the basis of the responses, frequency distributions of the constraints were done for different aspects of husbandry practices. The results revealed that lack of awareness about the importance of heat detection, lack of knowledge about proper weight at first breeding of heifer and pregnancy diagnosis, poor perception of the AI service and poor conception rate of AI, lack of awareness about the importance of proper height of the roof, lack of knowledge about proper ventilation of the house, lack of knowledge about the daily feed requirement of dairy cows, high cost of animal feeds, inadequate knowledge of the farmers about colostrum feeding, lack of knowledge about timely and regular vaccination of animals, lack of awareness about the importance of full hand milking, lack of knowledge about clean milk production, lack of knowledge about the importance of value addition, high price of urea to treat the straws and lack of adequate finance were the major constraints that influenced the decision to adopt improved dairy husbandry practices in the study area. Hence, focusing on these constraints and eliminating/reducing them could lead to increase in the rate of adoption of improved dairy husbandry practices and ultimately increase milk production in the area.

description: This study is carried out to assess the levels of total chromium in the chrome plating wastewater and its removal by chemical precipitation using lime water suspensions. The wastewater produced from chrome electroplating is huge and complex which far exceed the assimilative capacity of nature and lead to an irreversible health and ecological consequence. Wastewater samples are collected from Homicho Ammunition Engineering Industry. The physicochemical analysis and heavy metal concentrations determined for different parameters using FAAS and titration. The average results obtained are: total dissolved solids (20,848.20 ± 0.35 mg/L), total suspended solids 889.55 ± 0.43 mg/L, electrical conductivity (182.26 ± 0.11 mS/cm ) , pH (2.64 ± 0.01), Cr+6 (196,960 ± 0.70 mg/L), Cr+3 (117,20 ± 0.55 mg/L), total Cr (2,155,33 ± 428.99 mg/L), Fe (3,514.50 ± 21.55 mg/L), Pb (1,070.75 ± 3.35 mg/L) and Cu (1,239.16 ± 18.74 mg/L). The samples collected starting from 2002 to 2012 were analyzed separately and the results were found to be significantly different (p<0.05) for each parameter. The stored wastewater treated through chemical precipitation by reducing Cr+6 with ferrous sulfate in acidic media, (pH 2 to 3.5) to trivalent chromium. Chemical precipitation process was found to be efficient in the removal of chromium from the effluent at different pH (73.68% at pH 7.5; 82.60% at pH 8 and 99.98% at pH 8.5).The treatment of chromium is pH dependent. The percentage removal achieved for the other metals is Cu 89.71%, Fe 94.82%, and Pb 98.27% at pH 8.5 respectively. The best removal for chromium is 99.98% at pH 8.5 leaving 0.16 mg/L in the filtrate which is below permissible limits as per the Ethiopian Environmental protection guidelines. Therefore, this method of removal was found to be cost effective and environmentally friendly.

description: As gene delivery tools, lentiviral vectors (LV) have broad applications in chimeric antigen receptor therapy (CAR-T). Large-scale production of functional LV is limited by the adherent, serum-dependent nature of HEK293T cells used in the manufacturing. HEK293T adherent cells were adapted to suspension cells in a serum-free medium to establish large-scale processes for functional LV production in a stirred bioreactor without micro-carriers. The results showed that 293 T suspension was successfully cultivated in F media (293 CD05 medium and SMM293-TII with 1:1 volume ratio), and the cells retained the capacity for LV production. After cultivation in a 5.5 L bioreactor for 4 days, the cells produced 1.5 ± 0.3 × 107 TU/mL raw LV, and the lentiviral transduction efficiency was 48.6 ± 2.8% in T Cells. The yield of LV equaled to the previous shake flask. The critical process steps were completed to enable a large-scale LV production process. Besides, a cryopreservation solution was developed to reduce protein involvement, avoid cell grafting and reduce process cost. The process is cost-effective and easy to scale up production, which is expected to be highly competitive.

description: We address the problem of downlink beamforming for mitigating the co-channel interference in multi-cell OFDMA networks. Based on the network utility maximization framework, we formulate the problem as a non-convex optimization problem subject to the per-cell power constraints, in which a general utility function of SINR is used to characterize the network performance. Some classical utility functions, such as the proportional fairness utility, the weighted sum-rate utility and the {$α$}-fairness utility, are subsumed as special cases of our formulation. To solve the problem in a distributed fashion, we devise an algorithm based on the non-cooperative game with pricing mechanism. We give a sufficient condition for the convergence of the algorithm to the Nash equilibrium (NE), and analyze the information exchange overhead among the base stations. Moreover, to speed up the optimization of the beam-vectors at each cell, we derive an efficient algorithm to solve for the KKT conditions at each cell. We provide extensive simulation results to demonstrate that the proposed distributed multi-cell beamforming algorithm converges to an NE point in just a few iterations with low information exchange overhead. Moreover, it provides significant performance gains, especially under the strong interference scenario, in comparison with several existing multi-cell interference mitigation schemes, such as the distributed interference alignment method.
