text: This article discusses the additive manufacturing and post-processing of axicons,
and their performance evaluation using attenuation and near-field-measurements
based fundamental techniques. The axicons are manufactured using the materials
cyclic olefin copolymer (TOPAS) and polymethyl methacrylate (PMMA), for their
respective use in terahertz and near-infrared applications. An emphasis is placed
on the dip-coating-based post-processing. Interval dipping and intermittent hardening
lead to excellent surface finish and transparency in case of additively-manufactured
near-infrared axicons. The dip-coated samples exhibit surface roughness of sub
10nm, and a uniformly distributed thin layer coating over the axicon surface.
In addition to the improved surface finish and transparency, the coatings are
also closely matched in refractive index to the axicon material. Such post-processed
axicons pave the way for rapid-prototyping and production.

text: The use of additive manufacturing for rapid prototyping of near-infrared and
terahertz components provides seamless and error-free production. This article
discusses the additive manufacturing and post-processing of axicons and their
performance evaluation using attenuation and near-field-measurements based fundamental
techniques. The axicons are manufactured using the materials cyclic olefin copolymer
(TOPAS) and polymethyl methacrylate (PMMA), for their respective use in terahertz
and near-infrared applications. The optical and terahertz components manufactured
using traditional 3D-printing processes, e.g., fused filament fabrication or stereolithography
apparatus exhibit high surface roughness in the range of 15 ± 2.5 µm, resulting
in undesired propagation and scattering in the near infrared wavelengths. This
research work proposes an economical post-processing technique for additively
manufactured terahertz and near-infrared axicons for applications in multispectral
characterization, e.g., bio-sensing. The authors used an enhanced method of dip-coating,
which involves interval dipping and intermittent hardening to achieve better surface
finish. An emphasis is placed on interval dipping and intermittent hardening,
which lead to excellent transparency in case of additively-manufactured near-infrared
axicons. The dip-coated samples exhibit surface roughness below 10 nm. With the
use of heated resin material as the coating layer, due to reduced viscosity, the
resin material distributes uniformly over the surface of the 3D-printed terahertz
and near-infrared axicons. The authors also observed that the DOF length deviation
between unprocessed and enhanced dip-coated axicons remains within the measurement
error estimation from analytical calculations. In addition to the improved surface
finish and transparency, the coatings are also closely matched in refractive index
to the axicon material. Such post-processed axicons pave the way for producing
a wide array of systems in the fields of communication, imaging, and bio-sensing.

text: Additive manufacturing of optical, electrical, and mechanical components is
a beneficial approach for the rapid prototyping of components and error elimination,
with short turnaround times. However, additively manufactured components usually
have rough surfaces that need post-processing, particularly for optical components,
where the surface roughness must be a small fraction of the wavelength. We demonstrate
an innovative and economical approach by dip-coating with the same resin used
for printing in a simple post-processing step, providing high transparency to
the 3D-printed optical components and reducing surface roughness while achieving
perfect index matching of the coating layer. The surface roughness of the 3D-printed
optical components drops to 5 nm (arithmetic average) after the dip-coating process.
We observed significant performance enhancements after comparing the unprocessed
optical components and the dip-coated optical components, including optical transparency
and a shiny surface finish for previously rough surfaces.

text: "Additive manufacturing of optical, electrical and mechanical components is
a beneficial approach for rapid prototyping of components and error elimination
with short turn around times. However, additively manufactured components usually
have rough surfaces which need post-processing, in particular for optical components
where the surface roughness must be a small fraction of the wavelength. We demonstrate
an innovative and economical approach by dip-coating with the same\r\nresin as
used for printing, providing high transparency of the 3D-printed optical components
and reduced surface roughness with perfect index matching of the coating layer
in a simple post processing step. The surface roughness of the 3D-printed optical
components drops to 5 nm (arithmetic average) after the dip-coating process. We
observed significant performance enhancement after comparing the unprocessed optical
components and dip-coated optical components, including achieving optical transparency
and shiny surface finish of previously rough surfaces."

text: Early weight gain is a primary goal in the treatment of anorexia nervosa (AN)
and associated with more favorable discharge weights and clinical outcomes. Activity
urges, that is, a motivational state to engage in activity, have been suspected
to delay early weight gain, but their prognostic role remains barely explored.
Here, we investigated whether acute (state‐like) activity urges at treatment onset
would predict within‐person weight gain in patients with AN during the initial
2 weeks of inpatient treatment. Adults with AN from an inpatient unit (N = 53)
completed an activity urges measure at treatment onset, and weight changes were
monitored for the duration of their treatment. Regression analyses, controlling
for admission body mass index and other patient variables (i.e., patient age and
AN subtype), found that higher state activity urges were associated with lower
initial weight gain. Mediation analyses showed that differences in early weight
changes further linked higher activity urges at admission to lower discharge weights.
An activity urge cutoff value of 2.76 for distinguishing between cases with optimal
and suboptimal initial weight gain is proposed. We discuss potential mechanisms
of the link between activity urges and early weight gain and the implications
of activity urges as a prognostic factor for improving weight restoration during
AN treatment.

text: The concepts of collective management of housing and urban spaces are being
revisited within the contemporary discussions about community-driven approaches
and practices and, in particular, related to the revitalization of residential
neighbourhoods. This research identifies the concepts of self-management and social
ownership of housing in the post-World War II period in Yugoslavia as an important
legacy of Yugoslav urban planning and housing policies. Although they were subsequently
neglected, these concepts can contribute to contemporary global discussions about
housing affordability and the role of community in ensuring spatial and social
equality. New Belgrade mass housing blocks—the main site for testing the new dwelling
concepts, in terms of both policies and modernist design—are the object of this
research. The article is mainly a theoretical analysis of the issues of common
interest and engagement, common good, and common spaces which played a decisive
role in its design. The study applies interpretative and correlational research
methods in re-theorizing these concepts and their underlying narratives. It traces
how the perspectives on the collective practices and spaces evolved over time,
revealing a correlation between changed social practices and the spatial deterioration
of the New Belgrade mass housing blocks. The study highlights the importance of
both collective practices and common spaces for addressing housing issues, emphasizing
their instrumentality, and potentiality for rearticulating the dialogue between
public and private, engaging citizens in interactive and inclusive decision-making
and co-creation of the urban reality.

text: 'The paper studies local community centres (Serbian: centar mesne zajednice
– CMZ) of post–war mass housing neighbourhoods in New Belgrade. Those were designed
and built in 1970s as multifunctional centres with facilities and programmes complementary
to the housing blocks: socio–cultural, commercial (grocery stores), daily services
(post office, bank, crafts, etc.) spaces for socio–political activities and office
spaces for the local community. The local community centres significantly increased
quality of life of the residents, liveability and socialisation in the neighbourhoods.
Furthermore, one of the main aims of these spaces was to enable actual realisation
of the self–management in local communities. This paper reflects on the ideological
and theoretical basis for their conceptualisation, referring to Edvard Kardelj,
one of the main ideologues of self–management and originator of the local community
concept in Yugoslavia. Moreover, the paper investigates: how the local community
centres were planned, designed and programmed, and how they were spatially integrated
in the existing residential blocks; how their organisational and governing role
has been neglected over time, and their main purpose altered; and what are potentials
and socio–spatial capacities for their future reuse. Reaffirmation of local community
centres as utilitarian, governing and social space is recognized as key for promoting
participation and collaborative governance in New Belgrade blocks, as well as
for improving social connections, solidarity and sense of belonging in these neighbourhoods.
As such, the local community centres could be one of the main factors of revitalisation
of the blocks, increasing vitality and improving quality of life of the residents.
Furthermore, the local community centres could have a major role in unlocking
the potential of institutions and individuals towards new effective urban governance
structures, as well as institutionalising citizens{\textquoteright} participation
and bottom-up governance as direct democracy in the city today.'

text: 'The main purpose of bovine colostrum, being the milk secreted by a cow after
giving birth, is to transfer passive immunity to the calf. The calves have an
immature immune system as they lack immunoglobulins (Igs). Subsequently, the supply
of good quality bovine colostrum is required. The quality of colostrum is classified
by low bacterial counts and adequate Ig concentrations. Bacterial contamination
can contain a variety of human pathogens or high counts of spoilage bacteria,
which has become more challenging with the emerging use of bovine colostrum as
food and food supplements. There is also a growing risk for the spread of zoonotic
diseases originating from bovines. For this reason, processing based on heat treatment
or other feasible techniques is required. This review provides an overview of
literature on the microbial quality of bovine colostrum and processing methods
to improve its microbial quality and keep its nutritional values as food. The
highlights of this review are as follows: high quality colostrum is a valuable
raw material in food products and supplements; the microbial safety of bovine
colostrum is increased using an appropriate processing-suitable effective heat
treatment which does not destroy the high nutrition value of colostrum; the heat
treatment processes are cost-effective compared to other methods; and heat treatment
can be performed in both small- and large-scale production.'

text: Flocculation filtration in deep bed is one of the techniques to achieve advanced
phosphorus removal. In addition to particle retention and phosphorus removal,
granular activated carbon may serve as a filtration medium but also as an adsorption
bed for micropollutants. The aim of the study was to investigate the simultaneous
elimination of total phosphorus (TP) and selected micropollutants. In the first
part of the study the target phosphorus threshold of 0.2 mg/L TP in the filtrate
was achieved in a dual-bed media filter with anthracite and sand up to filter
velocities of 16 m/h. By using a detailed sampling protocol and headloss curves,
the influence of different operation modes on retention could be identified. Afterwards,
the filter media were replaced by three types of GAC. In all filter beds substantial
differences were found in the mode and efficiency of particle retention. This
led to different filter run times, which is one of the main parameters for efficient
and economical filter operation. Specific curves were generated for the different
bed materials showing the dependency of filter run time on the specific load of
suspended solids. Elimination of micropollutants in a GAC 4 × 8 mesh filter bed
was low due to coarse grains and low empty bed contact time (EBCT). The application
of GAC 8 × 14 mesh filter bed resulted in high elimination of most micropollutants.
These results can be applied when choosing filter bed material. This may involve
a compromise between filter run time and adsorption of micropollutants.

text: Granular activated carbon (GAC) adsorption, as well as ozonation in combination
with biodegradation was investigated in order to remove refractory organics from
biologically pre-treated process waters (PW) produced by the hydrothermal carbonization
(HTC) of spent grains and fine mulch. Kinetic tests revealed that the organics
in spent grains PW had much lower molecular weights than organics in fine mulch
PW. Moreover, isotherms showed that they were more strongly adsorbable. This was
confirmed in GAC column experiments, where the breakthrough curves could be predicted
fairly well by a dynamic adsorption model. On the other hand, ozonation had a
stronger effect on fine mulch PW with respect to an enhancement of the aerobic
degradability. Thus, the type of input material determines the properties of soluble
reaction products from the carbonization process that must be accounted for when
selecting the most suitable post-treatment method for HTC PW. However, adsorption
on granular activated carbon should always be the final stage.

text: Additive manufacturing technologies can provide cost and time advantages in
mold making, compared to traditional approaches. Nevertheless, their applicability
is not yet completely proven, especially in terms of surface finishing. The aim
of this research work is to create perfect mold inserts by Selective Laser Melting
(SLM) and to optimize surface quality. Therefore a process is developed to reduce
the effort of surface quality optimization including a high flexibility in design.
The tested process shows that simple and affordable methods can lead to usable
molds with only minor restrictions in terms of appearance. Due to the initial
reduction of layer thicknesses and distinct settings of laser melting parameters,
the surface smoothness is significantly enhanced during the SLM building process.
Subsequently blasting, manual grinding, as well as polishing operations, enable
a selective smoothening of the surface up to a polished finish. As a result, the
built tool parts can be used instantly for injection molding.
