description: Through an in-depth ethnographic case study, we explore water management practices within the Jiroft County province in Iran and discuss the applicability of indigenous knowledge of regional water management to the resource governance of arid regions across the world. We explore, through qualitative analysis, the relationship between community social structure, indigenous knowledge, water management technologies and practices, and water governance rules under conditions of anthropogenic climate change. From participant observational and interview data (n = 32), we find that historically-dependent community roles establish a social contract for water distribution. Cultural conventions establish linked hierarchies of water ownership, profit-sharing and social responsibility; collectively they construct an equitable system of role-sharing, social benefit distribution, socio-ecological resilience and adaptive capacity in the face of climate change-induced drought. We conclude that the combination of hierarchical land ownership-based water distribution and what we term ‘bilateral compensatory mutual assistance’ for the lowest-profit agricultural water users, provides a model of spontaneous common pool resource management that bolsters community drought resilience. We use this case to proffer recommendations for adapting other centralized, grey infrastructure and regulatory models of water management from lessons learned from this spontaneous adaptive management case.

description: Characterized by inequalities along gender, income, caste, and ethnic differences, urban areas are especially vulnerable to climate risks. Recognizing this, cities are adapting through infrastructural, ecosystem-based, institutional, and behavioural interventions at multiple scales. However, the extent to which these interventions enable or constrain the achievement of specific Sustainable Development Goals (SDGs) remains unclear. Using a systematic review, we evaluate the impacts of urban adaptation options on SDG 5 (gender equality), This review highlights that the urban adaptation literature tends to focus inordinately on women's differential (and additional) vulnerability to climate risks with limited evidence on the gendered outcomes of adaptation interventions. We find that although some adaptations such as urban agriculture interventions unequivocally increase agency for women, early warning systems and building risk awareness through public messaging showed mixed effects, with the outcomes depending on the implementation of the intervention and socio-cultural context. Further, the analysis indicates that adaptations such as urban agriculture can positively impact agency but, may show negative interactions with other indicators such as women's paid and unpaid work. We also identify key knowledge gaps and reflect on expanding the scope of SDG 5 to take a more intersectional and relational approach to gender equality.
Grid Services for Measurements on Digital Wireless Communications Systems
Creators: name: Napolitano, Aniello
Publisher: name: Università degli Studi di Napoli Federico II
Year: 2009

description: The research activity accounted for in this Ph.D thesis belongs to the general field of electrical and electronic measurement. The attention is focused on the implementation of GRID services for performance assessing of digital wireless communication systems. The original contribution consists in the development of two original measurement methods, the former allows measuring the modulation quality of systems compliant with IEEE 802.16d-2004 standard by means of any hardware characterized by a enough sample rate and input band width, and the latter carries out reliability and efficiently the in-service measurements also in presence of in-channel interferences. The high computational burden experienced during the wide experimental phase by proposed methods has encouraged their implementation according to GRID Service paradigm. Respect to the classic Web Service, GRID Service provides the possibility of both sharing the proposed methods among researches and technicians who work on the same topics, and processing some proposed methods stages in parallel way on several calculus nodes, thus reducing the whole processing time. Differently from the normal GRID Service, the developed GRID Services involve the measurement instrumentation, such digital acquisition systems and waveform generator, other than the calculus nodes. Suitable strategies for discovering, accessing, setting the measurement instruments have to be provided for. To this aim, new GRID architecture has been proposed, which virtualizes the measurement instruments into new components, namely instrumentation devices, and makes use of classic mechanisms already presented in GRID architecture, such as PBS scheduler, for dealing with the instruments discovery issue. To take advantage from the proposed GRID Services, a proper web portal is also implemented. An intense experimental phase is executed for assessing the methods and GRID Services performance by applying emulated and real communication signals. Measurement results are analyzed and compared to those achievable through the application of existing methods and/or instrument available on the market. Particular attention is also made to the processing time measurement of GRID Service with respect to a sequential implementation, in order to evidence the gains provided by a parallel implementation.
Maximum scour around cylinders induced by wave and current action
Creators: name: Abusbeaa, Abubaker Mohamed
Publisher: name: University of British Columbia
Year: 2010

description: The maximum possible scour around cylindrical structures under the action of combined wave and current was investigated in this study. A review of the literature showed that there are no adequate theories or methods for predicting maximum possible scour depths around structures under the action of wave plus current. Development of such a scour prediction is of considerable economic importance for the design of offshore structures. The study started with experimental tests of the scour around cylindrical structures and a comparison was made between scour under steady currents alone, waves alone and combined wave and current conditions. Existing theories for scour and flow velocities under waves alone and currents alone were analyzed and sets of experiments were performed for the three flow conditions of waves alone, currents and waves plus currents using three sediment size ranges and five cylinder sizes. The dependence of maximum scour on both cylinder size and sediment size for the three flow cases was studied and graphical relationships were established. The maximum scour under combined wave and current at threshold conditions in the approaching flow was investigated in detail and the dependence of maximum scour on this critical threshold flow criterion was shown. The maximum scour depth can be roughly estimated using this study provided that the flow conditions, sediment properties and structure dimensions are defined.
Widely linear filtering in modern MIMO transceivers
Creators: name: Lipardi, Maddalena
Publisher: name: Università degli Studi di Napoli Federico II
Year: 2009

description: This thesis deals with the multiple-input multiple-output (MIMO) equalization with widely linear (WL) filtering. The WL filtering outperforms the linear one in presence of rotationally variant signals, with no significant complexity increase. It has been used in order to compensate the transmitter and receiver in-phase and quadrature (IQ) imbalance and to design the optimum constellation transmitted over a channel known at the receiver, according to minimum mean square error (MMSE) criterion. Moreover, with reference to OFDM-OQAM systems, it has been proposed an ad hoc MMSE WL-DF equalizer which performs a selective MIMO equalization according to the characteristics of the MIMO channel describing the system. The synthesis of the equalizer has been carried out by an algorithm which exhibits minimum storage requirements. The equalizer has proved efficient for OFDM-OQAM systems, achieving the best trade-off between performance and complexity.

description: In Riesz space theory it is good practice to avoid representation theorems which depend on the axiom of choice. Here we present a general methodology to do this using pointfree topology. To illustrate the technique we show that almost f-algebras are commutative. The proof is obtained relatively straightforward from the proof by Buskes and van Rooij by using the pointfree Stone-Yosida representation theorem by Coquand and Spitters.

description: A well known theorem by Alexander-Hirschowitz states that all the higher secant varieties of $V_{n,d}$ (the $d$-uple embedding of $\mathbb{P}^n$) have the expected dimension, with few known exceptions. We study here the same problem for $T_{n,d}$, the tangential variety to $V_{n,d}$, and prove a conjecture, which is the analogous of Alexander-Hirschowitz theorem, for $n\leq 9$. Moreover. we prove that it holds for any $n,d$ if it holds for $d=3$. Then we generalize to the case of $O_{k,n,d}$, the $k$-osculating variety to $V_{n,d}$, proving, for $n=2$, a conjecture that relates the defectivity of $σ_s(O_{k,n,d})$ to the Hilbert function of certain sets of fat points in $\mathbb{P}^n$.

description: "Hot Jupiter" extrasolar planets are expected to be tidally locked because they are close (<0.05 astronomical units, where 1 AU is the average Sun-Earth distance) to their parent stars, resulting in permanent daysides and nightsides. By observing systems where the planet and star periodically eclipse each other, several groups have been able to estimate the temperatures of the daysides of these planets. A key question is whether the atmosphere is able to transport the energy incident upon the dayside to the nightside, which will determine the temperature at different points on the planet's surface. Here we report observations of HD 189733, the closest of these eclipsing planetary systems, over half an orbital period, from which we can construct a 'map' of the distribution of temperatures. We detected the increase in brightness as the dayside of the planet rotated into view. We estimate a minimum brightness temperature of 973 +/- 33 K and a maximum brightness temperature of 1212 +/- 11 K at a wavelength of 8 microns, indicating that energy from the irradiated dayside is efficiently redistributed throughout the atmosphere, in contrast to a recent claim for another hot Jupiter. Our data indicate that the peak hemisphere-integrated brightness occurs 16$\pm$6 degrees before opposition, corresponding to a hot spot shifted east of the substellar point. The secondary eclipse (when the planet moves behind the star) occurs 120 +/- 24 s later than predicted, which may indicate a slightly eccentric orbit.

description: R E S U M OO objetivo desta pesquisa consiste em realizar uma análise das publicações sobre a proteção de linha de costa do manguezal, bem como avaliar os 20 autores entre homens e mulheres mais citados nesta temática. Para isto, foi realizada a coleta de dados na base Web of Science, usando as strings de pesquisa: “Wind or storm protection” and “mangrove”, considerando como filtros os artigos científicos publicados até o ano de 2021. Em seguida, os metadados bibliográficos foram exportados no formato “BibTex”, registrados e processados no software RStudio por meio do pacote “bibliometrix”, e por fim, foi realizada uma triagem manualmente dos artigos. 238 artigos foram analisados de 1991 a 2021, em que durante os últimos dez anos foram registradas 84% das produções, sendo 2020 e 2021 os anos com maiores números de publicações, 36 e 29 artigos, respectivamente. Os artigos, em geral, utilizam ferramentas e geotecnologias como processamento de dados, análise estatística, imagens de satélite e softwares, para comparar áreas atingidas antes e depois do desastre de tempestades e tsunamis, além de estratégias de restauração ambiental e mitigação das consequências. Os trabalhos analisados reconhecem o papel relevante dos manguezais na proteção costeira, atestando que esses ecossistemas necessitam de conservação para a perpetuação dos benefícios ofertados. Dentre os 20 autores com maior número de citações no tema, apenas 20% são mulheres, constatando a desigualdade de gênero. Diante disso, esse trabalho também ratifica a importância em promover financiamento e políticas voltadas à mulher na ciência, para reduzir a disparidade quanto ao gênero.Palavras-Chaves: Análise global, áreas úmidas costeiras, serviços ecossistêmicos de regulação, proteção de ventos e tempestades.

description: We use HST/ACS to study the resolved stellar populations of the nearby, nearly edge-on galaxy NGC4244 across its outer disk surface density break. The stellar photometry allows us to study the distribution of different stellar populations and reach very low equivalent surface brightnesses. We find that the break occurs at the same radius for young, intermediate age, and old stars. The stellar density beyond the break drops sharply by a factor of at least 600 in 5 kpc. The break occurs at the same radius independent of height above the disk, but is sharpest in the midplane and nearly disappears at large heights. These results make it unlikely that truncations are caused by a star formation threshold alone: the threshold would have to keep the same radial position from less than 100 Myr to 10 Gyr ago, in spite of potential disturbances such as infall and redistribution of gas by internal processes. A dynamical interpretation of truncation formation is more likely such as due to angular momentum redistribution by bars or density waves, or heating and stripping of stars caused by the bombardment of dark matter sub-halos. The latter explanation is also in quantitative agreement with the small diffuse component we see around the galaxy.

description: We study lepton number violating and lepton number conserving semi-leptonic decays of heavy baryons $Λ_b^0$ to three charged leptons and a neutrino. The decays occur through two intermediate quasi-degenerate GeV-scale sterile neutrinos of either Majorana or Dirac type that can be on-shell. Interference between the intermediate heavy neutrinos leads to CP violation in the final states. Effect of neutrino oscillations between the heavy states are also considered in observables of interests, \emph{i.e.,} branching ratio, and the CP-asymmetry. Given the present constraints on the heavy-to-light mixing elements $|V_{eN}|$ and $|V_{μN}|$, CP-averaged branching ratio of $Λ_b^0\to (Λ_c,p)μμeν$ with intermediate Majorana neutrinos is almost two orders of magnitude larger than for the same with Dirac neutrinos, whereas, CP-averaged branching ratio of $Λ_b^0\to (Λ_c,p)eeμν$ is of the same order of magnitude for both Majorana and Dirac neutrino induced decays. CP-violation is found to be appreciable when the neutrino mass difference is comparable with the average decay widths.
A Coincidence Problem: How to Flow from N=2 SQCD to N=1 SQCD

Year: 2008
Subjects: subject: High Energy Physics - Theory (hep-th)

description: We discuss, and propose a solution for, a still unresolved problem regarding the breaking from $\N=2$ super-QCD to $\N=1$ super-QCD. A mass term $W=μ\Tr Φ^2 / 2$ for the adjoint field, which classically does the required breaking perfectly, quantum mechanically leads to a relevant operator that, in the infrared, makes the theory flow away from pure $\N=1$ SQCD. To avoid this problem, we first need to extend the theory from $\SU (n_c)$ to $\U (n_c)$. We then look for the quantum generalization of the condition $W^{\prime}(m)=0$, that is, the coincidence between a root of the derivative of the superpotential $W(ϕ)$ and the mass $m$ of the quarks. There are $2n_c -n_f$ of such points in the moduli space. We suggest that with an opportune choice of superpotential, that selects one of these coincidence vacua in the moduli space, it is possible to flow from $\N=2$ SQCD to $\N=1$ SQCD. Various arguments support this claim. In particular, we shall determine the exact location in the moduli space of these coincidence vacua and the precise factorization of the SW curve.

Master Functions and Equations for Perturbations of Vacuum Spherically-Symmetric Spacetimes

description: Perturbation theory of vacuum spherically-symmetric spacetimes is a crucial tool to understand the dynamics of black hole perturbations. Spherical symmetry allows for an expansion of the perturbations in scalar, vector, and tensor harmonics. The resulting perturbative equations are decoupled for modes with different parity and different harmonic numbers. Moreover, for each harmonic and parity, the equations for the perturbations can be decoupled in terms of (gauge-invariant) master functions that satisfy 1+1 wave equations. By working in a completely general perturbative gauge, in this paper we study what is the most general master function that is linear in the metric perturbations and their first-order derivatives and satisfies a wave equation with a potential. The outcome of the study is that for each parity we have two branches of solutions with similar features. One of the branches includes the known results: In the odd-parity case, the most general master function is an arbitrary linear combination of the Regge-Wheeler and the Cunningham-Price-Moncrief master functions whereas in the even-parity case it is an arbitrary linear combination of the Zerilli master function and another master function that is new to our knowledge. The other branch is very different since it includes an infinite collection of potentials which in turn lead to an independent collection master of functions which depend on the potential. The allowed potentials satisfy a non-linear ordinary differential equation. Finally, all the allowed master functions are gauge invariant and can be written in a fully covariant form.

Stress-intensity factors for V-notches in orthotropic plates using singular finite elements
Creators: name: Lum, Conroy
Publisher: name: University of British Columbia
Year: 2010

description: A finite element program utilizing singularity-enriched elements was developed to determine the stress-intensity factors for an arbitrary V-notch in a linear elastic orthotropic beam. The special elements allow computation of the stress-intensity factors without recourse to an extremely fine element mesh. An application of the program was made to wood. A pilot experiment involving rectangular end-notched wood beams verified the program as well as demonstrated the utility of the program in predicting failure loads due to rapid crack propagation emanating from V-notches. The effect of varying wood properties on the V-notch stress-intensity factor was examined. A procedure to establish the failure surface encompassing V-notches and cracks under all loading conditions using the program is presented.

description: Evidence is mixed regarding the economic benefits achieved by companies hiring large firms to audit their financial statements. The studies approaching this theme concentrate mostly on public companies in developed markets, while the effect on private firms in emerging markets is still an open question. This research explores this gap by analyzing whether private firms in the Brazilian sugarcane industry audited by a Big 4 have a lower cost of debt than those audited by a non-Big 4. For that, a unique, hand-collected, dataset was used. This paper contributes to the literature by providing evidence of the role of audit institutions in an environment lacking studies on private firms’ financial reports, especially in emerging economies. The empirical analysis does not indicate that the cost of debt is negatively influenced by the verification of financial statements by a high-quality auditor. Banks and credit unions, as the primary funding sources of the industry, condition the cost of debt reduction to the levels of tangibility, leverage, and profitability. We also contribute to the literature by demonstrating that lenders may have other soft information sources, obtained through banking relationship, which may substitute higher-quality auditor. The results hold after robustness checks and endogeneity concerns.

description: Describing how the properties of the interstellar medium combine across size-scales is crucial for understanding star formation scaling laws and connecting Galactic and extragalactic data of molecular clouds. We describe how the statistical structure of clouds, and its connection to star formation, changes from sub-parsec to kiloparsec scales in a complete region within the Milky Way disk. We build a census of molecular clouds within 2 kpc from the Sun using literature. We examine the dust-based column density probability distributions (N-PDFs) of the clouds and their relation to star formation traced by young stellar objects (YSOs). We then examine our survey region from the outside, within apertures of varying sizes, and describe how the N-PDFs and their relation to star formation changes with the size-scale. The N-PDFs of the clouds are not well described by any single simple model; use of any single model may bias the interpretation of the N-PDFs. The top-heaviness of the N-PDFs correlates with star formation activity, and the correlation changes with Galactic environment (spiral-/inter-arm regions). We find that the density contrast of clouds may be more intimately linked to star formation than the dense gas mass fraction. The aperture-averaged N-PDFs vary with the size-scale and are more top-heavy for larger apertures. The top-heaviness of the aperture N-PDFs correlates with star formation activity up to roughly 0.5 kpc size-scale, depending on the environment. Our results suggest that the relations between cloud structure and star formation are environment specific and best captured by relative quantities (e.g., the density contrast). Finally, we show how the density structures of individual clouds give rise to a kpc-scale Kennicutt-Schmidt relationship as a combination of sampling effects and blending of different galactic environments.

description: [ITALIANO] Argomento della presente tesi è l’applicazione di chimere al campo terapeutico e diagnostico. E’ stata innanzitutto realizzata una sintesi conveniente di monomeri Mmt-PNA, una nuova strategia per l’ottenimento di un linker oltre all’oligomerizzazione e purificazione di chimere PNA/DNA. Migliorando sia sintesi e purificazione dei monomeri che quella degli oligomeri è stato possibile ottenere chimere 3’PNA-DNA in elevata scala ed elevata purezza.
Le quantità ottenute di chimere pure ha consentito l’utilizzo di queste molecole per la prima volta in vivo in esperimenti in cui è stata studiata la capacità di duplex chimeriche di interagire e bloccare HMGB1, una proteina che lega il DNA ed è implicata in molte malattie infiammatorie.
Nella seconda parte di questa tesi è descritta la sintesi di monomeri Mmt-alanil PNA realizzata presso l’Institut für Organische und Biomolekulare Chemie della Georg-August-Universität di Göttingen (Germania) sotto la direzione del Prof. Dr. Ulf Diederichsen. Oligomeri di alanil PNA formano complessi stabili di doppi filamenti in accordo con lo schema di riconoscimento delle nucleobasi di Watson e Crick, ma non riconoscono DNA o RNA complementari. I monomeri corrispondenti sono building block adatti per la sintesi in fase solida di chimere alanil PNA-DNA utili in diagnostica in un approccio molecular beacon. / [ENGLISH] This thesis deals with the application of PNA/DNA chimeras to therapeutic and diagnostic problems.
As first point a convenient synthesis of Mmt PNA monomers, a new route to a Mmt linker and the oligomerisation of PNA/DNA chimeras were realised. By improving both monomer and chimeric oligomer synthesis and purification it was possible to obtain 3’PNA-DNA chimeras in large scale and high purity. The obtained quantities of pure chimeras allowed us to use these molecules for the first time in vivo in experiments where the ability of the chimera:chimera duplex to interact and block HMGB1, a DNA binding protein that is implied in many inflammatory diseases, was studied in collaboration with Dr. Marco Bianchi of “Ospedale S. Raffaele” (Milan) and with Dr. Silvano Fumero of the Creabilis Therapeutics S.P.A. (Ivrea).
As second point of this thesis the synthesis of Mmt alanyl-PNA monomers, realised in the Institut für Organische und Biomolekulare Chemie of the Georg-August-Universität of Göttingen, under the direction of Prof. Dr. Ulf Diederichsen, is described for all canonical nucleobases. Alanyl-PNA oligomers form specific and stable double strands based on nucleobase recognition, but do not recognize complementary DNA/RNA. The corresponding monomers are building blocks suitable for the solid phase assembly of chimeric alanyl-PNA/DNA molecules useful in the molecular beacon approach and were synthesized in this thesis.

description: We report the first results of our systematic search for strongly lensed quasars using the spectroscopically confirmed quasars in the Sloan Digital Sky Survey (SDSS). Among 46,420 quasars from the SDSS Data Release 3 (~4188 deg^2), we select a subsample of 22,683 quasars that are located at redshifts between 0.6 and 2.2 and are brighter than the Galactic extinction corrected i-band magnitude of 19.1. We identify 220 lens candidates from the quasar subsample, for which we conduct extensive and systematic follow-up observations in optical and near-infrared wavebands, in order to construct a complete lensed quasar sample at image separations between 1'' and 20'' and flux ratios of faint to bright lensed images larger than 10^{-0.5}. We construct a statistical sample of 11 lensed quasars. Ten of these are galaxy-scale lenses with small image separations (~1''-2'') and one is a large separation (15'') system which is produced by a massive cluster of galaxies, representing the first statistical sample of lensed quasars including both galaxy- and cluster-scale lenses. The Data Release 3 spectroscopic quasars contain an additional 11 lensed quasars outside the statistical sample.

description: In the last few years, interest in monomolecular layers of transition metal dichalcogenides (TMDs) has been driven by their unusual electronic and optical properties, which are very attractive for designing functional elements of new generation nanoelectronics. Recently, experimental evidence has appeared for the formation of a high-temperature strongly bound electron-hole liquid (EHL) in TMD monolayers. Strong binding of charge carriers is due to a significant decrease in the screening of the Coulomb interaction in monolayer heterostructures. In this work, the gas--liquid phase transition in a system of electrons and holes in quasi-two-dimensional heterostructures based on TMDs is considered and the critical parameters of such a transition are calculated. The metal-insulator transition is described and the phase diagram for such heterostructures is constructed.

description: We study emission of a single photon from a spherically symmetric cloud of N atoms (one atom is excited, N-1 are in ground state) and present an exact analytical expression for eigenvalues and eigenstates of this many body problem. We found that some states decay much faster then the single-atom decay rate, while other states are trapped and undergo very slow decay. When size of the atomic cloud is small compared with the radiation wave length we found that the radiation frequency undergoes a large shift.

description: A superglass is a phase of matter which is characterized at the same time by superfluidity and a frozen amorphous structure. We introduce a model of interacting bosons in three dimensions that displays this phase unambiguously and that can be analyzed exactly or using controlled approximations. Employing a mapping between quantum Hamiltonians and classical Fokker-Planck operators, we show that the ground state wavefunction of the quantum model is proportional to the Boltzmann measure of classical hard spheres. This connection allows us to obtain quantitative results on static and dynamic quantum correlation functions. In particular, by translating known results on the glassy dynamics of Brownian hard spheres we work out the properties of the superglass phase and of the quantum phase transition between the superfluid and the superglass phase.

Anomalias do nível do mar na costa do Rio Grande do Sul, Brasil (1993–2020): altimetria por satélite

description: R E S U M OAs zonas costeiras encontram-se suscetíveis a inúmeros riscos devido a sua localização na interface entre o mar e o continente. Muitos desses perigos estão associados a elevação do nível do mar sobre essas áreas, muitas vezes por consequência de eventos climáticos extremos. Em um planeta com o clima em mudança é fundamental caracterizar as diferentes regiões costeiras para entender as mudanças a que estarão submetidas. Esse estudo pretende quantificar as médias anuais de anomalias do nível do mar (SLA) na costa do Rio Grande do Sul (RS) entre os anos de 1993 e 2020. Para isso utilizamos dados de altimetria por satélites pós-processados pelo software X-TRACK (CTOH/LEGOS). Após a obtenção, organização e análise dos dados, foram calculadas as médias anuais da série histórica que demonstraram que até 2009 os valores eram negativos. A partir de 2010 os dados se tornaram positivos em uma escala ascendente. Nota-se também que 2020 é o ano com a variação positiva mais elevada. Dessa forma, podemos afirmar que os dados de satélite e o produto pós processado do X-TRACK são uma excelente alternativa para estudo do nível do mar regional em um país com poucos marégrafos e boias disponíveis.Palavras-Chaves: Altimetria, dinâmica costeira, mudanças climáticas, X-TRACK.

description: Because of its distinctive compositional properties and variability, low-speed ($\lesssim 450$ km s$^{-1}$) solar wind is widely believed to originate from coronal streamers, unlike high-speed wind, which comes from coronal holes. An alternative scenario is that the bulk of the slow wind (excluding that in the immediate vicinity of the heliospheric current sheet) originates from rapidly diverging flux tubes rooted inside small coronal holes or just within the boundaries of large holes. This viewpoint is based largely on photospheric field extrapolations, which are subject to considerable uncertainties and do not include dynamical effects, making it difficult to be certain whether a source is located just inside or outside a hole boundary, or whether a high-latitude hole will be connected to Earth. To minimize the dependence on field-line extrapolations, we have searched for cases where equatorial coronal holes at central meridian are followed by low-speed streams at Earth. We describe 14 examples from the period 2014--2017, involving Fe XIV 21.1 nm coronal holes located near active regions and having equatorial widths of $\sim$3$^\circ$--10$^\circ$. The associated in situ wind was characterized by speeds $v\sim 300$--450 km s$^{-1}$ and by O$^{7+}$/O$^{6+}$ ratios of $\sim$0.05--0.15, with $v$ showing the usual correlation with proton temperature. In addition, consistent with other recent studies, this slow wind had remarkably high Alfvénicity, similar to that in high-speed streams. We conclude that small coronal holes are a major contributor to the slow solar wind during the maximum and early post-maximum phases of the solar cycle.
