Abstract. Chrismanto D, Lastuti NDR, Suwanti LT, Hastutiek P, Suprihati E, Kurniawati DA, Winarso A. 2023. Species diversity of Entamoeba and gastrointestinal parasites as co infection in pigs in Kupang, East Nusa Tenggara, Indonesia. Biodiversitas 24: 233-240. Protozoa Entamoeba spp. is the causative agent of amoebiasis that can infect humans and livestock. Several species that infect pigs are E. suis, E. polecki, E. histolytica, and E. coli. However, microscopic examination through morphological identification of parasites couldn't determine the genus and species level identity, leading to misdiagnosis. Therefore, molecular techniques are needed for accurate diagnosis with species-specific primers. In this study, 100 fecal samples were collected from pig farms in Kupang, East Nusa Tenggara Province, Indonesia. This study aims to identify, using molecular techniques, the presence of Entamoeba spp. with the SSUrRNA gene as a marker to determine the diversity of Entamoeba species in pigs and to detect co-infection with other gastrointestinal parasites in Kupang. The result was found: E. suis 98% (98/100), E. polecki 44% (44/100), E. polecki ST3 10% (10/100), and E. coli 20% (30/100) spread on pig farms in 8 villages in Kupang. Furthermore, E. polecki ST3 and E. coli finding show that pigs in several areas in Kupang are infected with potentially zoonotic species. In addition to finding various species of Entamoeba by Polymerase Chain Reaction (PCR) amplification, based on microscopic examination, other gastrointestinal parasites were also found as co-infections, namely: Eimeria sp. (34%), Cystoisospora suis (30%), Strongyloides sp. (34%), Oesophagostomum sp. (51%), Metastrongylus sp. (18%), and Trichuris suis (8%). That is the first report concerning mixed infections with E. suis, E. polecki ST3, E. coli, and other gastrointestinal parasites in pigs in Kupang, Indonesia.

Published: February 2023

We analyze the multiple steady states of a multimode inhomogeneously broadened ring laser and their linear stability. From these results, we predict hysteresis and pulsations for appropriate control parameters.
The effects of the inhomogeneous broadening on the unstable behavior of single-mode lasers have been documented extensively, both theoretically and experimentally1. Only limited attention, however, has been paid to the multimode extension of this problem2, in spite of the fact that the earliest multimode analysis for a homogeneously broadened ring laser appeared more than 15 years ago3.
Optical Design of i-Line Stepper for Microlithography
Authors: Lin Dajian , Lee Zhan , Zhou Chongxi 
Published: February 2023

Double telecentric configuration of an optical projection lens with alignment through lens wafer-to-reticle and uniform illumination pinciple of optical system for micro­lithography are discribed in the paper. To meet requirement of optical transfer function (OTF) for i-line lithography, the relation between photolithographic resolution (R) and numerical aperture (NA) is discussed. As an example, we have designed a new double telecentric projection lens with NA=0.42, magnification M=-l/5, image field size 15mmx15mm (21.2mm diametre) and conjugate distance 602mm.
Optical design program ZEMAX-XE is used to calculate image qualities of the i-line lens. The calculating results indicate wavefront aberrations < λ/4 and MTF >0.55 across the entire field when spatial frequency is 715 c/mn and wavelength is 365+/-3mn. This means the photolithographic resolution of 0.7um could be realized. The illumination uniformizer called the integrator consists of an array of 81 small square lens elements. The illumination non-uniformity of+/-2% could be realized by using our simulation program OPTENG to calculate light intensity distribution on tire illuminated image plane.

Authors: Rabinovich E. M. , Smolyakov G. A. , Tuchin V. V. 
Published: February 2023

Space - modulation characteristics of the emission (SMCE) of stripe - geometry DH lasers without lateral confinement have been studied both experimentally and theoretically.
Experimentally , the modulation phase dependence on the lateral beam coordinate was found. We suggest the displacement of a laser lateral pattern under the direct current modulation to be responsible for this phenomenon.
Theoretically, the injection current - induced laser pattern displacement has been demonstrated by direct numerical solution of the corresponding one - dimensional wave equation, with the complex permittivity being taken of the asymmetric Epstein layer form.

Published: February 2023

Background
There is growing interest in using social media to improve pregnant women’s well-being. This study aimed to evaluate the effects of social media (Snapchat) dissemination of health-promoting interventions on knowledge of oral health during pregnancy among pregnant women in Saudi Arabia.

Materials and methods
Using a single-blinded parallel group randomized controlled trial design, 68 volunteers were assigned to either a study group (SG) or a control group (CG). The SG received information about oral health during pregnancy via Snapchat, while the CG received the same information using WhatsApp. The participants were assessed three times: T1 prior to the intervention, T2 immediately following the intervention, and T3 as a follow-up 1 month later.

Results
A total of 63 participants completed the study in the SG or CG. According to paired t-test, total knowledge scores in the SG and CG increased significantly from T1 to T2 (p < 0.001) and from T1 to T3 (p < 0.001), but there was no significant change from T2 to T3 in either the SG or CG (p  =  0.699 and p  =  0.111, respectively). Using t-test, no significant differences were found between the SG and CG at T2 (p  =  0.263) or T3 (p  =  0.622). Also using t-test, no significant differences were found in the scores of the SG and CG from T2 to T1 (p  =  0.720), T3 to T2 (p  =  0.339), or T3 to T1 (p  =  0.969).

Conclusions
Using social media (e.g., Snapchat and WhatsApp) as a health-promoting intervention is a promising method for improving women’s knowledge about oral health during pregnancy for short term. However, further studies are needed to compare social media with conventional standard lecturing methods. also, to assess the longevity of the impact (short or long term).
Real movement or systematic errors? – TLS-based deformation analysis of a concrete wall
Authors: Jost Berit , Coopmann Daniel , Holst Christoph , Kuhlmann Heiner 
Published: February 2023

Abstract
Performing deformation analyses with high accuracy demands using terrestrial laser scanners is very challenging due to insufficient knowledge about the error budget and correlations. Terrestrial laser scans suffer from random and systematic errors that degrade the quality of the point cloud. Even though the vast majority of systematic errors can be calibrated, remaining errors or errors that vary with time or temperature influence spatially neighboring points in the same way. Hence, correlations between the measurements exist. Considering area-based deformation analyses, these correlations have two effects: On the one hand, they reduce the effective number of measurements in the point cloud, which mainly influences the decision of whether the movement is significant or not. On the other hand, correlations caused by systematic errors in the scanner can lead to a misinterpretation as a deformation of the object. Within this study, we analyze the deformation of a concrete wall (9.50 m height, 50 m width), and we develop a workflow that avoids the misinterpretation of correlated measurements as deformations of the object. Therefore, we first calibrate the scanner to reduce the influence of systematic errors. Afterwards, we use the average of two-face measurements from several scanner stations to eliminate remaining systematic errors and correlated measurements. This study demonstrates that systematic effects can lead to errors of a few millimeters that are likely to be interpreted as small deformations, and it provides a strategy to avoid misinterpretation. Hence, it is inevitable either to model or to eliminate systematic errors of the scanner while performing a precise deformation analysis with a magnitude of a few millimeters.
Conditions forcing the existence of relative complements in lattices and posets
Authors: Chajda Ivan , Länger Helmut 
Published: February 2023

Abstract
It is elementary and well known that if an element x of a bounded modular lattice

L

$ \mathbf L $

has a complement in

L

$ \mathbf L $

then x has a relative complement in every interval [a, b] containing x. We show that the relatively strong assumption of modularity of

L

$ \mathbf L $

can be replaced by a weaker one formulated in the language of so-called modular triples. We further show that, in general, we need not suppose that x has a complement in

L

$ \mathbf L $

. By introducing the concept of modular triples in posets, we extend our results obtained for lattices to posets. It should be remarked that the notion of a complement can be introduced also in posets that are not bounded.

Abstract
In this paper, by using Sadovskii’s fixed point theorem and the properties of the measure of noncompactness, we establish some sufficient conditions for the asymptotic stability results of nonlinear neutral integro-differential equations with variable delays. The results presented in this paper improve and generalize some results in the literature. An example is considered to illustrate our main results.
Tribological properties of UHMWPE/PAANa/Ph4Sn composite materials in seawater lubrication
Authors: Yang Tian , Zhan Shengpeng , Jia Dan , Tu Jiesong , Ma Lixin , Duan Haitao 
Published: February 2023

Abstract
The blended composites with ultra-high molecular weight polyethylene (UHMWPE) as the matrix polymer, sodium polyacrylate (PAANa), and tetraphenyltin (Ph4Sn) as fillers were prepared by hot compression molding process. The friction and wear behavior of GCr15 balls with composites mating pairs under the seawater environment was explored, and the friction and wear mechanism was analyzed. The results show that adding PAANa, a polyelectrolyte material, can effectively reduce the friction coefficient of UHMWPE/PAANa/Ph4Sn composites. The wear resistance of composites increased significantly with increasing Ph4Sn content compared with pure UHMWPE, and the best wear resistance was observed at 1% content. The primary wear mechanism of UHMWPE/PAANa/Ph4Sn composites changed from adhesive wear of pure UHMWPE to plastic deformation at lower PAANa and Ph4Sn contents and finally to adhesive wear and spalling. This work provides a theoretical basis for preparing and applying other polymer blend composites.

An Experimental Study on Compressive Strength of the Concrete Containing Type II Cement and Tire-Rubber Particles at Various Ages
Authors: Hassan Vanhari Seyyed Meyssam , Gholhaki Majid 
Published: February 2023

Abstract
Compressive strength of concrete is one of the most important properties of concrete for designers and quality control engineers and the engineering community is interested in predicting 28-day compressive strength of concrete because of the strength of concrete at younger ages such as 7 days. Portland cement type II is one of the most widely used cements, which has the highest consumption because of the weather conditions and the construction process of structures in Iran. The relation for computing the compressive strength at the age of t based on the 28-day strength has been presented only for cement types I and III and there is no relation for type II cement in ACI codes of practice. In this study, the compressive strength of concrete at the age of t based on the 28-day strength has been experimentally investigated for the concretes containing cement type II and tire rubber particles. To this end, three cement grades of 350, 400, and 450 kg/m3 as well as water-to-cement ratios (w/c) of 0.5 and 0.65 were used. Moreover, cement was replaced with tire-rubber particles at contents of 5 to 20 % by volume. The values for α and β coefficients to be applied in the concrete strength relation based on the age of 28 days according to ACI209 for the concretes containing type II cement and tire-rubber particles were obtained equal to 3.13 and 0.91 as well as 3.32 and 0.9, respectively. Finally, the best mix design was found to do with the ordinary concrete with cement grade of 400 kg/m3, w/c of 0.5 and tire-rubber particles of 5 % that leads to the highest compressive strength by which the environmental issues could be markedly mitigated.

Published: February 2023

Background and aim. The SARS-CoV-2 outbreak in Romania was followed by the declaration of an Emergency State and the subsequent lockdown. As all the schools and universities ceased onsite activities, the teaching process continued exclusively online, on different platforms, such as Microsoft Teams or Zoom.
Objectives. The aim of this cross-sectional study is to evaluate how the lifestyle changes imposed by the Covid-19 lockdown and online lectures influenced the learning experience of Romanian dental students, as their point of view could bring new information which might contribute to improving the teaching process.
Methods. The questionnaire had 28 items, each with either a Likert Scale or a multiple-choice option and was distributed in April 2020, one month after implementation of circulation restrictions and social distancing.
Results. Compared to classical teaching, we found that the online teaching process had a lower efficiency, with a higher satisfaction level for online courses, but lower for online practical teaching activities. The absence of human interaction was found to be detrimental to the teaching process.
Conclusion. Despite the lower efficiency of online learning, it was a good alternative that helped students continue their education in the situation created by the outbreak of Covid-19. For higher learning efficiency, a compromise method consisting of online courses and onsite practical training could be a better alternative.
The Late Lithuanian Greimas: Intentions and Reception
Authors: Mačianskaitė Loreta 
Published: February 2023

The main research material consists of Algirdas Julius Greimas’s texts written during the transition period, when Lithuania was parting with Soviet rule (1989–1991), mainly his “Baltos lankos” column in Literatūra ir menas weekly periodical as well as various texts by other authors on Greimas’s texts along with memoirs, letters and obituaries. The study has two aims: 1) to find a conceptual approach for analyzing Lithuanian texts by the late Greimas, 2) to identify points of change in the semiosphere of Lithuanian culture. Greimas’s own semiotic method, namely, a structure of four Senders is used to describe his texts. The theoretical context of Juri Lotman’s cultural semiotics is a more permanent intellectual context for this study, and some of the terms are useful in more than one aspect. The readers’ attitudes towards Greimas’s texts highlight how the core and periphery change in the semiosphere: the period of cultural activity and openness and the internal cultural barriers appearing at the same time, the gradual passivation of culture and cases of sporadic creative relationships.

La ciudadanía miscelánea del liberalismo radical en Colombia
Authors: López Lopera Liliana María 
Published: February 2023

El presente artículo intenta pensar el liberalismo radical colombiano desde viejas y nuevas preguntas que se hacen al liberalismo en el debate actual. Específicamente se mostraran los matices del concepto de ciudadanía postulado por el pensamiento radical a partir de la reconstrucción de las nociones de Estado, individuo y libertad. En la primera parte se realiza una caracterización desde la filosofía política, del liberalismo radical de mediados del siglo XIX. El argumento central de esta parte apunta a afirmar que el liberalismo radical se estructura a partir de la interacción entre los principios y presupuestos del libertarianismo (liberalismo individualista) y el republicanismo, con la primacía del primero sobre el segundo. Complementariamente se presenta la influencia del utilitarismo y el socialismo en el pensamiento de los radicales, doctrinas que fueron asimiladas de manera artificial, mas no determinante, dentro del pensamiento del radicalismo. En la segunda parte del texto se caracteriza el ideal de ciudadanía subyacente al pensamiento liberal radical. En este apartado el argumento apunta a señalar que el resultado de la interacción entre los principios enunciados atrás es la construcción de una noción miscelánea de ciudadanía. En un tercer apartado se contrasta la noción de ciudadanía de los radicales con la noción de ciudadanía de los conservadores. Finalmente, en el cuarto apartado se rescata la idea de libertad y dignidad subyacente al pensamiento radical a partir de la reconstrucción de sus argumentos a favor de la abolición de la pena de muerte y de la esclavitud.
