ABSTRACT The 2-nitrobenzoic acid degradation pathway of Pseudomonas fluorescens strain KU-7 proceeds via a novel 3-hydroxyanthranilate intermediate. In this study, we cloned and sequenced a 19-kb DNA locus of strain KU-7 that encompasses the 3-hydroxyanthranilate meta-cleavage pathway genes. The gene cluster, designated nbaEXHJIGFCDR, is organized tightly and in the same direction. The nbaC and nbaD gene products were found to be novel homologs of the eukaryotic 3-hydroxyanthranilate 3,4-dioxygenase and 2-amino-3-carboxymuconate-6-semialdehyde decarboxylase, respectively. The NbaC enzyme carries out the oxidation of 3-hydroxyanthranilate to 2-amino-3-carboxymuconate-6-semialdehyde, while the NbaD enzyme catalyzes the decarboxylation of the latter compound to 2-aminomuconate-6-semialdehyde. The NbaC and NbaD proteins were overexpressed in Escherichia coli and characterized. The substrate specificity of the 23.8-kDa NbaC protein was found to be restricted to 3-hydroxyanthranilate. In E. coli, this enzyme oxidizes 3-hydroxyanthranilate with a specific activity of 8 U/mg of protein. Site-directed mutagenesis experiments revealed the essential role of two conserved histidine residues (His52 and His96) in the NbaC sequence. The NbaC activity is also dependent on the presence of Fe2+ but is inhibited by other metal ions, such as Zn2+, Cu2+, and Cd2+. The NbaD protein was overproduced as a 38.7-kDa protein, and its specific activity towards 2-amino-3-carboxymuconate-6-semialdehyde was 195 U/mg of protein. Further processing of 2-aminomuconate-6-semialdehyde to pyruvic acid and acetyl coenzyme A was predicted to proceed via the activities of NbaE, NbaF, NbaG, NbaH, NbaI, and NbaJ. The predicted amino acid sequences of these proteins are highly homologous to those of the corresponding proteins involved in the metabolism of 2-aminophenol (e.g., AmnCDEFGH in Pseudomonas sp. strain AP-3). The NbaR-encoding gene is predicted to have a regulatory function of the LysR family type. The function of the product of the small open reading frame, NbaX, like the homologous sequences in the nitrobenzene or 2-aminophenol metabolic pathway, remains elusive.

Background: The neonatal behavioral assessment scale (NBAS) was primarily developed to aid in the assessment of full-term neonates. The aim of this study was to detect if the NBAS was also valuable in the assessment of preterm neonates. Materials and Methods: We assessed 112 infants at a neonatal unit using the NBAS, 4th edition. The inclusion criteria included an oxygen saturation level between 88–95% and a heartrate of 100–205 beats per minute. Infant neurobehavior was assessed using the NBAS. Results: For full-term and preterm neonates, we observed that the NBAS enabled us to assess both groups of infants and gave relevant information pertaining to them. We found a significant correlation between the average week of gestation and response to touch, sensory input, peak of excitement, cost of attention, hand-to-mouth, and quality of alertness. Conclusions: The NBAS is a valuable scale for evaluating the neurobehavior of preterm neonates. The week of gestation at birth affects certain aspects of neurobehavior, such as response to sensory input, putting hand to mouth, peak of excitement, and cost of attention. The NBAS as an individually structured assessment may help in planning for early rehabilitation and intervention for this vulnerable population.

Naga Bhasma is one of the herbo-metallic preparations used in Ayurveda and claimed to possess broad spectrum of therapeutic efficacy. The Standard manufacturing Procedures of Naga Bhasma prepared by two methods by changing Bhavana dravya were developed with latex (NBAD) and leaf juice of Calatropis procera (NBAS). Shuddha Manahshila (Realgar) was taken as a Maraka Dravya. Naga Bhasma was prepared by using classical guidelines described in Rasa Ratna Samuchhaya. Total 10 Puta are required for preparation of Naga Bhasma. Total three batches of each group were prepared. An Average of 8.83% increase in weight of Manahshila was observed after Shodhana and 1600 ml Ardraka Swarasa was required for levigation. An Average of 12.57 & 18.55% increase in weight was found in NBAD and NBAS groups’ respectively. An Average of 181.33 ml of latex and 182.66 mlleaf juice of Calatropis procera were required for Bhavana. Grey coloured Naga Bhasma was obtained after 10 Puta in EMF. Both the Bhavana dravya i.e. latex and leaf juice were found similar in view of pharmaceutical and analytical aspect, hence method of preparation of Naga Bhasma with Arkapatra Swarasa may be preferred in view of large scale manufacture, cost, labour and availability of drugs.

AbstractBiallelic pathogenic variants in the neuroblastoma amplified sequence (NBAS) gene were firstly (2015) identified as a cause of fever-triggered recurrent acute liver failure (RALF). Since then, some patients with NBAS deficiency presenting with neurologic features, including a motor delay, intellectual disability, muscular hypotonia and a mild brain atrophy, have been reported. Here, we describe a case of pediatric patient diagnosed with NBAS deficiency due to a homozygous c.2809C > G, p.(Pro937Ala) variant presenting with RALF with severe hyperammonemia, acquired microcephaly and progressive brain atrophy. Not reported in the literature findings include severe hyperammonemia during ALF episode, and neurologic features in the form of acquired progressive microcephaly with brain atrophy. The latter raises the hypothesis about a primary neurologic phenotype in NBAS deficiency.

Upon infection, severe acute respiratory syndrome—coronavirus 2 (SARS-CoV-2) is predicted to interact with diverse cellular functions, such as the nonsense-mediated decay (NMD) pathway, as suggested by the identification of the core NMD factor upframeshift-1 (UPF1) in the SARS-CoV-2 interactome, and the retrograde transport from the Golgi to the endoplasmic reticulum (ER) through the endoplasmic reticulum–Golgi intermediate compartment (ERGIC), where coronavirus assembly occurs. Here, we investigated the expression and localization of the neuroblastoma-amplified sequence (NBAS) protein, a UPF1 partner for the NMD at the ER, participating also in retrograde transport, and of its functional partners, at early time points after SARS-CoV-2 infection of the human lung epithelial cell line Calu3. We found a significant decrease of DExH-Box Helicase 34 (DHX34), suppressor with morphogenetic effect on genitalia 5 (SMG5), and SMG7 expression at 6 h post-infection, followed by a significant increase of these genes and also UPF1 and UPF2 at 9 h post-infection. Conversely, NBAS and other genes coding for NMD factors were not modulated. Known NMD substrates related to cell stress (Growth Arrest Specific 5, GAS5; transducin beta-like 2, TBL2; and DNA damage-inducible transcript 3, DDIT3) were increased in infected cells, possibly as a result of alterations in the NMD pathway and of a direct effect of the infection. We also found that the expression of unconventional SNARE in the ER 1, USE1 (p31) and Zeste White 10 homolog, ZW10, partners of NBAS in the retrograde transport function, significantly increased over time in infected cells. Co-localization of NBAS and UPF1 proteins did not change within 24 h of infection nor did it differ in infected versus non-infected cells at 1 and 24 h after infection; similarly, the co-localization of NBAS and p31 proteins was not altered by infection in this short time frame. Finally, both NBAS and UPF1 were found to co-localize with SARS-CoV-2 S and N proteins. Overall, these data are preliminary evidence of an interaction between NBAS and NBAS-related functions and SARS-CoV-2 in infected cells, deserving further investigation.

Introduction The consequences for the COVID-19 pandemic in the newborns of affected mothers remains unknown. Previous clinical experiences with other infections during pregnancy lead to considered pregnant women and their offspring especially vulnerable for SARS-COV-2. That is, the underlying physiopathological changes caused by the infection (e.g. storm of cytokines, micro-coagulation in placenta or vertical transmission) could clearly compromise fetal neurodevelopment. Objectives To analyze the impact of maternal SARS-COV-2 infection during pregnancy in early neurodevelopment of infants gestated during the COVID-19 pandemic period compared to those gestated immediately prior (2017-2021). Methods 212 pregnant women (14% infected) were followed throughout their pregnancy and postpartum, including newborn development. SARS-COV-2 infection was serologically confirmed during pregnancy. The Brazelton Neonatal Assessment Scale (NBAS) was administered at 6 weeks old by a trained neonatologist to evaluate neurological, social and behavioral aspects of newborn’s functioning. Differences in NBAS scores between cases and controls were tested by ANOVAs. All the analysis were adjusted for maternal age, sociodemographic status, anxious-depressive symptomatology, infant’s sex and gestational age at birth and NBAS, and for the period of gestation (previous or during COVID-19 pandemic). Results NBAS social interactive dimension was significantly decreased in those infants exposed to prenatal SARS-COV-2 (F=4.248, p=.043), particularly when the infection occurred before the week 20 of gestation. Gestation during COVID-19 pandemic did not alter NBAS subscales. Conclusions SARS-COV-2 infection during pregnancy seems to be associated with lower NBAS scores on social dimension in 6 weeks old exposed newborns. Disclosure No significant relationships.

The National Banking Acts (NBAs) of 1863–1864 established rules governing the amounts and locations of interbank deposits, thereby reshaping the bank networks. Using unique data on bank balance sheets and detailed interbank deposits in 1862 and 1867 in Pennsylvania, we study how the NBAs changed the network structure and quantify the effect on financial stability in an interbank network model. We find that the NBAs induced a concentration of interbank deposits at both the city and bank levels, creating systemically important banks. Although the concentration facilitated diversification, contagion would have become more likely when financial center banks faced large shocks. (JEL E44, G01, G21, G28, L14, N21)

Variations in the NBAS gene is known to cause a spectrum of phenotypes ranging from isolated recurrent acute liver failure (RALF) to a multisystemic presentation known as SOPH syndrome. Patients with SOPH present with optic atrophy, acute liver failure, short stature, and Pelger-Huet anomaly. We report the presence of a novel pair of biallelic heterozygous mutations c.5139-5T>G and c.2203-2A>G in the NBAS gene of a patient with SOPH syndrome. A 9-year-old patient was clinically diagnosed with SOPH following clinical laboratory analyses. Current interventions for managing the disease encompass IVIG, methylprednisolone, calcium, and vitamin D administration. Whole-exome sequencing (WES) results showed two mutations: c.2203-2A>G and c.5139-5T>G, in the NBAS gene, which had not been previously reported. Notably, we hypothesize that NBAS mutations could potentially contribute to the development of Fanconi syndrome, a clinical diagnosis reported in our patient. Our study also supports the renaming of SOPH to SOPHIA to allow early detection and effective treatment.

Purpose: To describe the clinical features of a rare case of NBAS-SOPH-like mutations; to emphasize special aspects of the ocular and oro-facial regions. Methods: Case report. Case Description: We present a 5-year-old girl initially examined for her dysmorphic features, mental delay, strabismus, and high myopia. During the funduscopic examination, we observed optic atrophy with narrow thinned arterioles with the light brown reflex of the central retina. A genetic assessment revealed NBAS-SOPH like mutation. An assessment by a team of orthodontists defined typical characteristics. Conclusions: NBAS mutations can also cause complex disease with a broad clinical spectrum ranging from isolated recurrent acute liver failure (RALF) to a multisystemic phenotype. Due to the heterogeneity of the expressions, a multispeciality approach to this situation is recommended.

ABSTRACT Pseudomonas fluorescens strain KU-7 is a prototype microorganism that metabolizes 2-nitrobenzoate (2-NBA) via the formation of 3-hydroxyanthranilate (3-HAA), a known antioxidant and reductant. The initial two steps leading to the sequential formation of 2-hydroxy/aminobenzoate and 3-HAA are catalyzed by a NADPH-dependent 2-NBA nitroreductase (NbaA) and 2-hydroxylaminobenzoate mutase (NbaB), respectively. The 216-amino-acid protein NbaA is 78% identical to a plasmid-encoded hypothetical conserved protein of Polaromonas strain JS666; structurally, it belongs to the homodimeric NADH:flavin mononucleotide (FMN) oxidoreductase-like fold family. Structural modeling of complexes with the flavin, coenzyme, and substrate suggested specific residues contributing to the NbaA catalytic activity, assuming a ping-pong reaction mechanism. Mutational analysis supports the roles of Asn40, Asp76, and Glu113, which are predicted to form the binding site for a divalent metal ion implicated in FMN binding, and a role in NADPH binding for the 10-residue insertion in the β5-α2 loop. The 181-amino-acid sequence of NbaB is 35% identical to the 4-hydroxylaminobenzoate lyases (PnbBs) of various 4-nitrobenzoate-assimilating bacteria, e.g., Pseudomonas putida strain TW3. Coexpression of nbaB with nbaA in Escherichia coli produced a small amount of 3-HAA from 2-NBA, supporting the functionality of the nbaB gene. We also showed by gene knockout and chemotaxis assays that nbaY, a chemoreceptor NahY homolog located downstream of the nbaA gene, is responsible for strain KU-7 being attracted to 2-NBA. NbaY is the first chemoreceptor in nitroaromatic metabolism to be identified, and this study completes the gene elucidation of 2-NBA metabolism that is localized within a 24-kb chromosomal locus of strain KU-7.

Traffic and Feature SW is a department based in Kista. At this department the main processor software, or MPSW in short, in Ericssons Radio Base Stations is tested prior to integration of new releases. Traffic and Feature SW, also called MPSW in this thesis, works closely with another department of Ericsson called RBS System I&V which tests the same software but for complete RBS nodes. MPSW uses black- and greybox scripted testing in regression suites that are executed on a daily basis. These regression suites are separated into different subsets of functionality that maps to the capabilities of the Radio Base Station software. The authors of this thesis has performed an implementation of automated test cases for a subset of the Radio Base Station software using an automated software tool called QuickCheck. These test cases were successfully integrated into the test framework and were able to find several issues with the main processor software and its subsystems in the Radio Base Station. The commissioner of this thesis have plans to further integrate the QuickCheck tool into the test framework, possibly automating test cases for several subsets of the Radio Base Station software. The authors have therefore analysed and put forth metrics that compares the testing of the Radio Base Station software using QuickCheck with the conventional regression test cases. These metrics covers areas such as the cost related to and the inherent capabilities of QuickCheck. The evaluation of these metrics was performed by the authors to give the commissioner decisive information. These evaluations showed that QuickCheck was able to generate complex message stuctures in complex sequences. QuickCheck was also able to shrink both the content of these messages and the length of the sequences of messages to be able to provide a minimal counterexample when a fault was discovered. The only metric that QuickCheck failed to support was to inherit functionality to support the handling of statistics from executions.

This project explores internet memes, pinpointing the utilisation of image macros by online-based basketball fans, as a cultural tool for communication, conversation, critique and debate. More specifically, this study focuses on how basketball fans, through image macros, are engaging with different facets of culture, beyond professional sports. The nature of internet memes allow users to create texts that express the tone of their feelings, and this research contends that the idiosyncratic nature of basketball memes are motivated by non-serious sports-related banter, and yet, can potentially offer legitimate cultural insight by often drawing on popular cultural myths and trends.

Nb-Si-Cr-Al-Mo base in situ composites with nominal compositions Nb-18Si-5Al-5Cr-5Mo (JG1), Nb-24Ti-18Si-5Al-5Cr-5Mo (JG2), Nb-24Ti-18Si-5Al-5Cr-2Mo (JG3), Nb-24Ti-18Si-5Al- 5Cr-2Mo-5Hf (JG4) and Nb-24Ti-18Si-5Al-5Cr-2Mo-5Hf-5Sn (JG6) were prepared by arc-melting followed by heat treatment. The effects of Mo, Ti, Hf and Sn additions on phase selection, phase transformations, microstructure and oxidation behaviour in the as cast and heat-treated in situ composites were investigated using XRD, SEM, and EPMA. All the alloys are classified as hyper-eutectic alloys since the betaNb5Si3 phase was formed in all the as cast microstructures. After heat treatment, the betaNb5Si3 partly transformed to the alphaNb5Si3 in the presence of Ti. The addition of Ti stabilised the betaNb5Si3 to lower temperatures and increased the solubilities of A1 and Cr in the Nb88. The lattice parameter of the Nb88 increased after heat treatment. This is attributed to the redistribution of solutes between the Nbss and the intermetallic phases and in particular the reduction in Si content. The NbaSi phase was formed in the as cast Hf-free alloys (JGl, JG2 and JG3). However, this phase was unstable at 1500°C and decomposed by a eutectoid transformation to Nb88 and alphaNb5Si3. The eutectoid decomposition was enhanced considerably by the Ti addition. The formation of Nb3Si was suppressed by the Hf addition. In the presence of Ti and Hf, there were Ti and Hf segregations in the Nb5Si3 phase. The Ti solubility in the Hf-rich Nb5Si3 was higher than in the Nb5Si3. The structure of the Nb5Si3 phase was mainly affected by the Hf addition, which prompted the formation of the alphaNb5Si3. The Hf-rich regions in the 5-3 silicide probably corresponded to the alphaNb5Si3, which was stable up to 1500° C in the presence of Hf. The alloying elements Hf and Sn preferentially substituted for Nb in the Nb5Si3 and Nbss, respectively. The addition of Sn had a significant effect on the Nbss, essentially leading to the formation of Sn-rich and Sn-poor parts in the solid solution in the as cast microstructure. In the presence of Sn, the Si solubility in the Nbss increased considerably whilst the Cr solubility decreased. The Sn addition promoted the formation of the Si-rich 014 Laves phase and stabilised this phase at 1300°C. The solubility range of Si in the C14 Laves phase formed in alloys of this study was ~ 6.6 to 10.5at.%. For the Ti containing alloys, titanium nitride formed near the surface of the specimen during heat treatment. Alloy Nb-18Si-15Cr (JG5) was studied to clarify the disputed three-phase fields (Nbss-1-0144- alphaNb5Si3 or Nbss-CrNbSi-l-alphaNb5Si3) near the Nb corner. The C14 Laves formed in both the as cast and heat treated samples. The results confirmed that the C14 Laves phase in the binary Nb-Cr system was stabilised by Si to lower temperatures.

In 2006, the NBA introduced the "one-and-done" rule that restricted high school graduates to enter directly into the NBA draft following high school. In turn, a high school prospect would essentially now have the option of playing professionally elsewhere (most likely overseas), enter the NBA's Developmental League, or play NCAA basketball. The rule has proved to be quite controversial, as it has had a great effect on both NBA and NCAA basketball, as well as the players. Various media outlets have been quite vocal not only about the rule itself, but the perceived effects it has had on both collegiate and professional basketball. This study will utilize framing theory to explore the way the media has presented the issue to the public, its causal interpretation, any moral evaluations necessary, and any solutions to the problem. This study will utilize a content analysis to analyze not only the media's presentation of the rule, but also what frames have been formed pertaining to the rule's successes and failures. The study will also aim to give a greater understanding of how the basketball media form frames.

Developing, implementing and evaluating models of care that reduce the caesarean section (CS) rate have been a health care priority in Australia since the 1990’s. There is minimal evidence examining models of care that aim to nurture women’s emotional well-being after CS; as well as providing consistent evidence-based information and promoting safe and successful vaginal birth in the subsequent pregnancy. Furthermore the experiences of midwives working in these models have been overlooked.

In my thesis, I present the methods I use to predict NBA games using matrix factorization. Matrix factorization is popular through the Netflix recommendation problem, but in general, one can apply it to data that are best modeled as the result of pairwise interaction. My thesis contains three parts. First, I explain how I model NBA prediction as a matrix factorization problem and use the basic low-rank matrix factorization approach to discover structure in the data. I also explain some differences between using matrix factorization for NBA prediction versus that in the Netflix recommendation problem. Second, I use probabilistic matrix factorization (PMF) to incorporate the fact that when two teams play each other, the scores will be different each time. Lastly, I incorporate supplementary information such as the date of the game by combining multiple PMF problems using Gaussian process priors. I replace the scalar latent features with functions of this supplementary information to aid with prediction.

AbstractBased on the highest pre-identified risk of flooding in the Glinščica catchment, our case study focused on identifying the benefits and opportunities of ecosystem services emerging from fully functioning ecosystems working as a natural assurance system arising from Nature-based solutions (NBS) through the implementation of a participatory approach. Together with our stakeholders we first, developed an NBS strategy for the Glinščica catchment and compared it to the business as usual, second, evaluated the ecosystem services provided by the simulated implementation of restoration and management measures selected and third, developed economic and financial instruments in the form of natural assurance schemes based on effective business models in the field of ecosystem services, green infrastructure and river restoration. This highlighted the importance of understanding the value of ecosystems in the long term. The participatory process was basically an iterative process in which expert studies formed the basis for stakeholder engagement on the one hand and the stakeholders’ perceptions and knowledge were shaping and directing the solutions on the other hand. Stakeholders eventually agreed that the developed strategy for water risk mitigation using NBSs in the Glinščica catchment is a viable alternative to existing grey infrastructure plans. However, the participatory process revealed several barriers to mainstreaming NBS and implementing an adaptive management approach in Slovenia, mostly in the governing and institutional systems. Through the participatory planning process, we built capacity and changed the perceptions of participating stakeholders regarding NBSs and their efficiency in providing multiple co-benefits in addition to the flood protection, which is usually the only function and benefit of grey measures.

AbstractNetwork-Based Biocomputation Circuits (NBCs) offer a new paradigm for solving complex computational problems by utilizing biological agents that operate in parallel to explore manufactured planar devices. The approach can also have future applications in diagnostics and medicine by combining NBCs computational power with the ability to interface with biological material. To realize this potential, devices should be designed in a way that ensures their correctness and robust operation. For this purpose, formal methods and tools can offer significant advantages by allowing investigation of design limitations and detection of errors before manufacturing and experimentation. Here we define a computational model for NBCs by providing formal semantics to NBC circuits. We present a formal verification-based approach and prototype tool that can assist in the design of NBCs by enabling verification of a given design’s correctness. Our tool allows verification of the correctness of NBC designs for several NP-Complete problems, including the Subset Sum, Exact Cover and Satisfiability problems and can be extended to other NBC implementations. Our approach is based on defining transition systems for NBCs and using temporal logic for specifying and proving properties of the design using model checking. Our formal model can also serve as a starting point for computational complexity studies of the power and limitations of NBC systems.

The Caribbean islands are among the 25 most-vulnerable nations in terms of disasters per-capita or land area, and climate change is only expected to intensify these vulnerabilities. The loss caused by climate events drags the ability of the Caribbean countries to invest in infrastructure and social programs, contributing to slower productivity growth, poorer health outcomes, and lower standards of living. Within this context, building resiliency should become a priority for the Caribbean countries. The series “Building a more resilient and low-carbon Caribbean”, focuses on improving the resiliency, sustainability and decarbonization of the construction industry in the Caribbean. The results show that increasing building resiliency is economically viable for the high-risk islands of the Caribbean, generating long term savings and increasing the infrastructure preparedness to the impacts of CC. The first three reports of the series analyze the economic losses caused by climate related events, the benefits of improving building resiliency to reduce those economic losses and the benefits of subsidized financing for resilient buildings in the Caribbean. The results show that increasing building resiliency is economically viable for the high-risk islands of the Caribbean, generating long term savings and increasing the infrastructure preparedness to the impacts of CC. This report Report 4: Infrastructure Resilience in the Caribbean through Nature Based Solutions - extends the previous analysis to examine the potential role for nature-based solutions (NBSs) in the region. The report first defines NBSs in the context of the Caribbean construction industry. It then considers specific NBS options that could be viable in the region. Next, the report reviews the status of NBS related projects in the Caribbean, including efforts supported by the IDB. This analysis also identifies several barriers to the development of NBSs in the region. Finally, the report suggests measures that can be taken to address these barriers and increase the use of NBSs in the Caribbean.

This rapid review examines literature around Nature-based Solutions (NbS), what are NbS, the pros and cons of NbS, design and implementation issues (including governance, indigenous knowledge), finance and the enabling environment. The breadth of NbS and the evidence base means that this rapid review only provides a snapshot of the information available, and therefore does not consider all types of NbS, nor all sectors that they have been used in. Considering this limited scope, this report highlights many issues, some of which are that Covid-19 has highlighted the importance of NbS, Pros of NbS include the low cost compared to infrastructure alternatives; the flexibility in addressing multiple climate challenges; potential co-benefits such as better water quality, improved health, cultural benefits, biodiversity conservation. The literature also notes the cons of NbS including slow adaptation or co-benefits, very context specific making effectiveness difficult to measure and many of the benefits are non-monetary and hard to measure. The literature consulted suggest a number of knowledge gaps in the evidence base for NbS effectiveness including lack of: robust and impartial assessments of current NbS experiences; site specific knowledge of field deployment of NbS; timescales over which benefits are seen and experienced; cost-effectiveness of interventions compared to or in conjunction with alternative solutions; and integrated assessments considering broader social and ecological outcomes

This discussion brief examines issues that must be addressed to help ensure that the design, governance and implementation of nature-based solutions (NbS) are just and equitable. The authors outline five principles to incorporate in NbS to achieve these goals, and they present a case study from a semi-informal settlement in Kenya that illustrates how such principles can be integrated into very preliminary efforts to set the stage NbS-oriented approaches to address multiple community-level concerns.
