The Rationale for Initiation and Continuation of Drug Abuse among Female Users: A Study of the Youth in Dhaka City
Authors: Mahbub Fabiha , Rahman Zia
Published: October 2023

This paper explores the reasons for female drug abuse in an urban setting. It is concerned with a gender-sensitive approach to one of the burning issues of the 21st century: abusive and non-medical consumption of drugs among the youth. It focuses on social learning theory, control theory, labeling theory, and strain theory to understand and explain why female drug abusers initiate and continue to abuse drugs. This phenomenological research was carried out in three female rehabilitation centers in the Dhaka region. Semi-structured interviews were conducted with twenty research participants: twelve female drug abusers (aged 12-30 years), seven rehabilitation personnel, and an official working with the Department of Narcotics Control, Bangladesh. This study finds some crucial reasons for initiating and continuing drug abuse among young female drug abusers, including traumatic experiences in life, the influence of peers and relatives, curiosity and sensation-seeking, easy access to and availability of unprescribed medicinal drugs, and social stigma.

Police Training for Managing Crime: With Special Reference to the Crime Data Management System of Bangladesh Police
Authors: Chowdhury Saber Ahmed
Published: October 2023

Initiations of the Crime Data Management System (CDMS) have led e-policing to a higher level of accuracy. The purpose of this study is to explore the existing training on CDMS, assess the training needed on CDMS, and recommend some ways forward. This study follows the mixed methodology where the primary data were collected by using surveys, key informant interviews (KIIs), and FGDs. This study reveals that since its initiation in 2005, CDMS has been working to depict case information, investigation reports, and crime analysis. In 2010, this system introduced online medium, and the Police Headquarters took over total control from the Crime Investigation Department (CID). Gradually in 2015, the Dhaka Metropolitan Police (DMP) introduced this system and in 2016, this system has been used at all police stations throughout the country. Moreover, this study also finds that from 2009 to 2020 more than half of the police officials did not receive any training on CDMS. The training receivers express their dissatisfaction with its short duration, and the aged and newly promoted officers remain vulnerable due to the partial training system. Additionally, police officials working in local thanas remain largely untrained and they also need to use this software on a regular basis.

The Rohingya Influx into Bangladesh’s Cox’s Bazar: Mapping Internal Security Threats
Authors: Ahmed Saifuddin , Siddiqui Muhammad Sazzad Hossain
Published: October 2023

Following the recent 2017 Rohingya influx, Bangladesh now hosts nearly one million Rohingyas. Being persecuted by the Myanmar state machinery and some local vigilantes, they fled for safe refuge in Bangladesh’s Cox's Bazar. Bangladesh sheltered them in 34 overcrowded camps located in the Teknaf and Ukhiya sub-districts of Cox’s Bazar. At present, Rohingyas are counted more than double compared to the local host population in these two areas. This study makes efforts to explicate why and how these stranded Rohingyas can be a security threat to Bangladesh. Theoretically, the study relies on security discourse; ecological and resource scarcity model; and relative deprivation theory. Under the qualitative research approach, the researchers conducted semi-structured interviews mainly with key informants and subject experts to gather field data. The study brings out that this overpopulation has perplexed the security milieu of the country and forecasts multifaceted internal security threats. Thus, the study offers salient policy recommendations to ameliorate the crisis response by neutralizing the identified and forecasted conflictual issues.

Authors: Ahmed Asib , Nahar Nazmun , Hossain Md Shamim , Shahriar Md
Published: October 2023

Urban Rooftop gardening (RTG) as a possible solution to food insecurity gets popularised due to the reduction of urban agricultural land and regarded as an effective climate change impact mitigation strategy. This paper identified the spatio-temporal changes of RTG practices in Dhaka Metropolitan Area (DMA) between 2016 and 2021. This evidence-based study was conducted based on manually extracted build-up (building rooftop) areas of DMA for 2021 and RTG areas of DMA for 2016 and 2021 through digitization from Google earth images using Google Earth Pro software. It is identified that the different zones of DMA experience changes in RTG differently based on their zonal development stages. The DMA received moderate increase (i.e. 15 percent) in RTG between 2016 and 2021 where the western part has greater RTG area than the eastern part. The study also reveals that planned residential areas have higher RTG areas than any other landuse whereas most Government/ Non-Government buildings have less RTG throughout the 20 zones of DMA and the Dhaka Cantonment area.

The Dynamics of the US-Iran Relationship after the Assassination of Qassem Suleimani: Explanations and Predictions
Authors: Faruque Jubaida Auhana , Durrat Fahima
Published: October 2023

The political dynamics of the US-Iran relationship have kept the two states always on the brink of the eruption of a major conflict. The targeted assassination of Major General Qassem Suleimani, one of the most consequential figures in Iranian military history, took the world to the brink of a global conflict on January 3, 2020. Fortunately, however, the subsequent events did not escalate to declared or undeclared war. This article provides a theoretical analysis of the conflict following the assassination of Major Suleimani to explain why and how war was avoided in this context. The analysis based on contemporary context, regional power dynamics, and relevant conditions illustrates how de-escalation of conflict was possible and argues why, in light of existing theories, there is hardly any possibility of a manifest war between the US and Iran in the near future despite prevailing in an alternate and latent form.

Potret perbandingan kebijakan harga pangan dengan realita harga beras, gula dan kedelai di tahun pertama pandemi Covid-19, Indonesia
Authors: Ivan's Eny , Sari Novia Ambar
Published: October 2023

Penyebab kelangkaan komoditi pertanian adalah karena kebijakan lockdown dan PSBB di awal pandemi, serta perilaku punic buying dari konsumen. Tujuan penelitian ini adalah membandingkan antara kebijakan harga komoditi beras, gula dan kedelai dengan realita harga yang terjadi di tahun pertama pandemi Covid-19.  Data sekunder yang digunakan dalam penelitian ini merupakan data harian dan bulanan harga komoditas dari SP2KP Kementerian Perdagangan dan BPS. Data tersebut dianalisis menggunakan grafik dan dibandingkan dengan kebijakan harga yang berlaku saat ini pada tiga komoditas tersebut. Hasil kajian menunjukkan bahwa kebijakan harga untuk komoditi beras, gula dan kedelai di tahun pertama pandemi Covid-19 belum menunjukkan keberpihakan kepada petani. Tingginya harga beras di tingkat ecer tidak berbanding lurus dengan kenaikan harga gabah di tingkat produsen. Harga gula yang fluktuatif dikarenakan periode impor gula bersamaan dengan periode panen tebu. Penghapusan tarif impor kedelai menjadi 0% menjadikan petani domestik bersaing secara face to face di pasar global.
The cause of the scarcity of agricultural commodities is due to the lockdown policy and PSBB (large-scale social restrictions) at the beginning of the pandemic Covid-19 and the punic buying behavior from consumers. The research objective was to compare the commodity price policies for rice, sugar, and soybeans with the price realities that occurred in the first year of the Covid-19 pandemic. Secondary data used in this study are daily and monthly data on commodity prices from SP2KP of the Ministry of Trade and BPS. The data is analyzed using charts and compared with the prevailing price policies for these three commodities. The study results show that the price policy for rice, sugar, and soybean commodities in the first year of the Covid-19 pandemic has not shown partiality to farmers. The high price of rice at the retail level is not directly proportional to the increase in grain prices at the producer level. Sugar prices fluctuate because the sugar import period coincides with the sugar cane harvest period. The elimination of import tariffs to 0% allows domestic farmers to compete directly in the global market.

Posyandu ialah kegiatan pelayanan dengan tujuan mendapatkan pelayanan kesehatan dasar, serta turunnya angka kematiaan ibu dan anak yang dibentuk untuk dan oleh masyarakat dari instansi terkait. Partisipasi masyarakat dibutuhkan dalam melaksanakan aktivitas posyandu. Penelitian ini bertujuan untuk mendefinisikan keikutsertaan kader posyandu dalam mendorong kontribusi masyarakat dan strategi kader posyandu dalam mendorong kontribusi masyarakat. Jenis penelitian yang digunakan adalah penelitian deskriptif dengan desain penelitian cross-sectional. Penelitian ini dilaksanakan pada bulan Oktober tahun 2021 di Posyandu Melati IV Kecamatan Medan Area, Kota Medan. Hasil penelitian didapatkan bahwa bentuk keikutsertaan yang didapatkan oleh ibu-ibu dibagi menjadi dua, yakni partisipasi dalam bentuk tenaga dan perwujudan program. Aspek utama yang membawa para ibu untuk berkontribusi dalam pelayanan kesehatan balita adalah lebih kepada aspek internal. Hal ini tampak dari wawasan dari ibu begitu pentingnya menjaga kesehatan. Kemudian aspek eksternal, seperti dukungan keluarga, yaitu suami setuju jika para ibu ikut berkontribusi. Aspek internal dan eksternal tersebut membuktikan sudah terlaksana sasaran dalam bidang kesehatan.
Posyandu is a service activity with the aim of obtaining basic health services, as well as reducing maternal and child mortality rates which are established for and by the community from the relevant agencies. Community participation is needed in carrying out posyandu activities. This study aims to define the participation of posyandu cadres in encouraging community contribution and the strategy of posyandu cadres in encouraging community contributions. The type of research used is descriptive research with a cross-sectional research design. This research was conducted in October 2021 at the Posyandu Melati IV, Medan Area District, Medan City. The results showed that the form of participation obtained by the mothers was divided into two, namely participation in the form of energy and program realization. The main aspect that brings mothers to contribute to health services for children under five is more to the internal aspect. This can be seen from the mother's insight into how important it is to maintain health. Then external aspects, such as family support, where the husband agrees if the mothers contribute. These internal and external aspects prove that the targets in the health sector have been achieved.
Analisis unsur hara N dan P serta tingkat kemiripan antar Lokasi KJA dan Non KJA di Perairan Waduk Cirata, Jawa Barat
Authors: Utami Endang Sri , Ivan’s Eny
Published: October 2023

Perairan Waduk Cirata merupakan perairan cascade hasil bendungan Sungai Citarum di Jawa Barat. Penelitian ini bertujuan untuk melihat karakteristik unsur hara N dan P terkait adanya aktivitas budidaya keramba jaring apung (KJA). Secara umum kandungan nitrat, nitrit dan ammonia di lokasi padat KJA memiliki nilai lebih tinggi dari lokasi non KJA Sedangkan secara vertikal antara kedalaman 1 m dengan 20 m memiliki nilai yang berbeda nyata. Di daerah KJA pada kedalaman 1 m nilai tersebut masing-masing berkisar 0,0940-0,2240; 0,0010-0,0020; 0,0280-0,0900 mg/l dan di kedalaman 20 m berkisar 0,1210-1,3970; 0,0010-0,0030; 0,0410-0,5310 mg/l. Konsentrasi nitrat, nitrit dan amonium pada kedalaman 1 m daerah non KJA masing-masing berkisar 0,0970-0,2180; 0,0010; 0,0420-0,1080 mg/l dan di kedalaman 20 m berkisar 0,3590-1,6380; 0,0010-0,0030; 0,1690-0,3780 mg/l. Berdasarkan hasil pengamatan diperoleh kandungan ortofosfat di daerah KJA dengan nilai lebih besar dan berbeda nyata dari daerah non KJA. Daerah dengan aktivitas padat KJA memiliki nilai kandungan ortofosfat lebih tinggi dikarenakan tingginya beban masukan nutrien yang berasal dari sisa pakan dan sisa hasil metabolisme ikan dalam KJA. Berdasarkan grafik dendrogram terlihat bahwa adanya aktivitas KJA mempengaruhi perbedaan karakteristik N dan P di Waduk Cirata.
Cirata Reservoir are cascade lake made by the Citarum River dam in West Java. This study aims to understand the characteristics of the nutrients N and P related to the activity of KJA cultivation. In general, the content of nitrate, nitrite and ammonia in intensive KJA locations has a higher value than non-KJA locations. Meanwhile, vertically between the depths of 1 m and 20 m have significantly different values. In the KJA area at a depth of 1 m these values ranged from 0.0940-0.2240, respectively; 0.0010-0.0020; 0.0280-0.0900 mg/l and at a depth of 20 m in the range 0.1210-1.3970; 0.0010-0.0030; 0.0410-0.5310 mg/l. The concentrations of nitrate, nitrite and ammonium at a depth of 1 m in non-KJA areas ranged from 0.0970-0.2180, respectively; 0.0010; 0.0420-0.1080 mg/l and at a depth of 20 m in the range 0.3590-1.6380; 0.0010-0.0030; 0.1690-0.3780 mg/l. Based on the observations, it was found that the orthophosphate content in the KJA area had a higher value and was significantly different from the non-KJA area. Areas with intensive KJA activity had a higher value of orthophosphate content due to the high load of nutrient input from feed residues and fish metabolism in the KJA. Based on the dendrogram graph, it can be known that the presence of KJA activity affects the differences in the characteristics of N and P in the Cirata Reservoir.

Published: October 2023

La piedra de uso en esculturas y edificios históricos sufre con el tiempo distintos fenómenos de alteración, tanto naturales como antrópicos, que ocasionan daños y pérdidas de material. Para tratar de paliar los efectos del así llamado “mal de la piedra” se han desarrollado y aplicado distintos tratamientos de conservación basados en el uso de materiales consolidantes y protectores. Estos tratamientos tienen la finalidad de devolver al material alterado sus características físico-mecánicas perdidas y protegerlo frente al deterioro futuro. Sin embargo, los consolidantes y protectores convencionales de uso común desde la segunda mitad del siglo XX, tales como los polímeros sintéticos y los (alquil)alcóxisilanos, en muchas ocasiones han demostrado una eficacia limitada y, en otras, incluso han agravado los problemas de alteración que se trataban de resolver. Como alternativa a estos tratamientos convencionales se ha propuesto, y aplicado en las últimas décadas, la carbonatogénesis bacteriana como método más eficaz, natural y ecológico para la protección y consolidación de piedra ornamental. Aquí presentamos una visión general de los fundamentos de la protección y consolidación de la piedra con bacterias y las variantes de este tratamiento, así como sus efectos tanto en ensayos de laboratorio como en aplicaciones in situ. Finalmente, se indican algunas conclusiones y futuras líneas de investigación para favorecer y potenciar el uso de esta biotecnología de conservación.
Materiales basados en cal aérea. Aprender del pasado para un futuro mejor
Authors: Giráldez Pilar , Vendrell Saz Màrius
Published: October 2023

La cal es uno de los materiales tradicionalmente usados en construcción histórica desde hace milenios, desde siempre ha sido un producto de km 0, que reabsorbe el CO2 usado en su fabricación (excepto el consumido en la combustión) y de una notable durabilidad a la vista de los innumerables monumentos construidos con ella y que una pervive. En el artículo se hace una revisión de la naturaleza y producción de la cal, de los procesos en puesta en obra y posterior endurecimiento y, sobre todo, de sus usos en situaciones constructivas variadas, algunas de ellas que requieren prestaciones importantes, como las obras hidráulicas o ciertos revestimientos. En este sentido se analiza con cierto detalle la posibilidad de mejora de las propiedades inherentes a la cal en base a la adición de substancias que modifican su comportamiento y hacen que endurezca en inmersión, que sea impermeable, que endurezca más rápidamente y que, en definitiva, aumente su durabilidad. La valoración que se hace del futuro de este material pasa por la recuperación de las tradiciones ancestrales mejorando ocasionalmente sus prestaciones. En definitiva, aprender del pasado para un futuro más sostenible.

As the data collection instrument, the 'Attitude Scale for Healthy Nutrition,' developed by TekkurşunDemir and Cicioğlu (2019), was used in the research. According to the results of the normality assumption, Student's T-test was utilized for pairwise comparisons, and One-Way Analysis of Variance (ANOVA) and Tukey's multiple comparison test were employed for multiple comparisons in the study. Significant differences were detected in the residence status variable of students in terms of the sub-dimensions of positive nutrition and malnutrition with the Attitude Scale for Healthy Nutrition (p<0,05). However, no significant differences were found in terms of gender regarding students' attitudes towards healthy nutrition and its sub-dimensions (p>0,05). Concerning physical activity, significant differences were observed in the sub-dimensions of information on nutrition, positive nutrition, and malnutrition with the Attitude Scale for Healthy Nutrition (p<0,05). Additionally, it was determined that students who lived with their families and engaged in sports had higher mean scores compared to others. Hence, living with family and regularly participating in exercise positively influenced students' attitudes towards healthy nutrition. In conclusion, organizing seminars and educational programs regarding healthy eating habits for students is of utmost importance.

The aim of this study to examine the relationship between the perception of success and coaching behavior of 14-18 age swimming athletes living in Aegean region. A total of 114 swimmers participated voluntarily. The "Children’s Version of the Perception of Success Questionare" (POSQ-CH) and “Coach Behavior Scale for Sport” (CBS-S) was used. The analysis of the data was evaluated with the SPSS. POSQ-CH score was 49.03 (very high); sub-dimensions, "Ego Orientation" (EO) score is 22.17 (high) and the "Task Orientation" (TO) score is 26.85 (very high). CBS-S score is 262.35 (quite high); sub-dimensions scores are between 23.43 (very low)-50.95 (very high). According to gender, a significant difference in POSQ-CH and GO sub-dimension and TS, PR and NR sub-dimension scores of CBS-S (p<0.05). Similarly, a significant difference in the EO sub-dimension according to coach gender, in the POSQ-CH and GO according to swimming style and in the EO and TS according to sport age (p<0.05). No correlation between POSQ-CH and CBS-S and its sub-dimensions; however, a positive and moderate relationship between the closeness to team captain score and CBS-S. It was determined that the swimmers in the relevant age range had high perception of achievement and perception of coach behavior, and the athletes were more goal-oriented. It can be said that the coach's physical-mental preparation, positive behavior, providing technical skill learning, directing the athlete correctly in terms of goal expectation, helping to provide appropriate and optimum competition strategy and negative behavior are not related to the swimmers' perception of success.

Authors: Pérez Ripossio Ramiro Nicolás
Published: October 2023

The article analyzes the migratory chains that constitute South American transvestites and trans women who reside in the Buenos Aires Metropolitan Area during the period 2017-2019, paying special attention to the role of godmothers. The migratory projects of these people are produced becauseof the hostility and vulnerability they experience in their surroundings and have different instances. One of them is the migratory chains that refer to the social capital necessary to be able to leave the sending society and settle in the receiving society. In this way, South American transvestites/trans women constitute diverse migratory chains that can be characterized as horizontal and vertical, being the godmothers key actors in their diasporas. The focus of the article is qualitative and the method used is grounded theory. According to a theoretical sample consisting of 41 interviews, the information was analyzed usingAtlas.Ti.
Logic, mathematics, physics: from a loose thread to the close link: Or what gravity is for both logic and mathematics rather than only for physics
Authors: Penchev Vasil
Published: October 2023

Gravitation is interpreted to be an “ontomathematical” force or interaction rather than an only physical one. That approach restores Newton’s original design of universal gravitation in the framework of “The Mathematical Principles of Natural Philosophy”, which allows for Einstein’s special and general relativity to be also reinterpreted ontomathematically. The entanglement theory of quantum gravitation is inherently involved also ontomathematically by virtue of the consideration of the qubit Hilbert space after entanglement as the Fourier counterpart of pseudo-Riemannian space. Gravitation can be also interpreted as purely mathematical or logical “force” or “interaction” as a corollary from its ontomathematical (rather than physical) realization. The ontomathematical approach to gravitation is implicit in general relativity equating it to operators in pseudo-Riemannian space obeying the Einstein field equation and also well-known by the “geometrization of physics”. Quantum mechanics shares the same by the separable complex Hilbert space and defining “physical quantity” by the Hermitian operators.
ANÁLISIS DE METODOLOGÍA DE RECUPERACIÓN DE MÓDULOS SOLARES FV DAÑADOS EN PARQUES SOLARES
Authors: Rojo Jeremias
Published: October 2023

El presente análisis tiene como objetivo describir la metodología utilizada para evaluar la reutilización de módulos solares fotovoltaicos dañados durante la fase de construcción de un parque solar. En esta etapa los módulos solares pueden presentar diversos daños físicos (rotura de vidrio superior, marcos, cables, conectores, etc.) o daños eléctricos internos (puntos calientes, celdas dañadas, corto circuito, entre otros). Generalmente estos módulos son descartados debido a que los niveles de exigencia respecto a la generación de energía son muy elevados, siendo inviable su utilización y fomentando el recambio de los mismos. En la mayoría de las construcciones de parques solares antes de comenzar con el montaje de los módulos se realizan ensayos de electroluminiscencia, en donde se descartan los módulos que cuentan con celdas dañadas. Luego, una vez instalados los módulos aprobados se realiza un trazado de curvas I-V, y en caso de que alguno de los módulos presente algún tipo de falla, también es descartado. Este tipo de práctica de control de calidad en la mayoría de los casos genera que una parte importante de módulos queden separados o fuera de uso. Sumado a esto, también se contabilizan los dispositivos que son dañados físicamente durante el montaje en sus respectivas estructuras de soporte, ya sea por errores en la manipulación o por efecto de algún evento climático/meteorológico (rafagas de viento de alta velocidad durante el momento del montaje o posibles tormentas).
PATRULHA COMERCIAL: IMPLANTAÇÃO DE UM NOVO MODELO DE POLICIAMENTO
Authors: Chagas Suelen Ramos
Published: October 2023

Este trabalho buscou analisar a implantação de uma nova modalidade de policiamento que vem sendo adotada pela Polícia Militar do Paraná: a Patrulha Comercial. Com base em estudos de diversos autores, percebeu-se que várias discussões surgem entorno dessa temática, tornando-se um tópico complexo e multifacetado. A literatura internacional vem mostrando que uma polícia que visa à obediência normativa se mostra mais eficaz. No Brasil, estudos têm mostrado que uma polícia que busca a legitimidade e a justeza procedimental tende a ser mais competente. Entretanto, a legitimidade da implantação de um novo modelo pode enfrentar diversos obstáculos, mas existem estratégias que podem ajudar a superá-los. Alguns dos obstáculos comuns incluem a resistência à mudança, cultura organizacional, capacitação e treinamento específico para o trabalho, aceitação da comunidade e falta de diretrizes claras para padronizar e orientar o trabalho dos policiais, fortalecendo tanto a relação entre pares, quanto a relação entre a polícia e a comunidade. Assim, sugere-se que a Patrulha Comercial busque o envolvimento da comunidade por meio de consultas, reuniões e outras ferramentas disponíveis para estabelecer diretrizes formais baseadas no policiamento comunitário, com o intuito de criar uma parceria entre a população e a Polícia Militar, contribuindo para a legitimidade e eficácia desse modelo de policiamento.
Ion—modified optimization of smart scaffolds in bone tissue regeneration
Authors: Basavarajappa Yashas
Published: October 2023

Bioactive glasses and Calcium Phosphate bioceramics have emerged as promising scaffold biomaterials for bone tissue engineering. These materials possess inherent osteoinductive properties that work to create a more suitable environment for bone tissue formation. Additionally, these scaffolds exhibit dissolution properties when submerged in physiological fluids in vivo and therefore can release different ions. Incorporating therapeutic ion-modifiers that have independently demonstrated their osteogenic favorability to these scaffolds can further increase environmental suitability. This review discusses the favorable properties of bioactive glasses and Calcium Phosphate bioceramics in the context of Bone Tissue Engineering as well as potential incorporable metal ion-modifiers.

Introduction

The midgut epithelium functions as tissue for nutrient uptake as well as physical barrier against pathogens. Additionally, it responds to pathogen contact by production and release of various factors including antimicrobial peptides, similar to the systemic innate immune response. However, if such a response is restricted to a local stimulus or if it appears in response to a systemic infection, too is a rather underexplored topic in insect immunity. We addressed the role of the midgut and the role of systemic immune tissues in the defense against gut-borne and systemic infections, respectively.

Methods

Manduca sexta larvae were challenged with DAP-type peptidoglycan bacteria – Bacillus thuringiensis for local gut infection and Escherichia coli for systemic stimulation. We compared the immune response to both infection models by measuring mRNA levels of four selected immunity-related genes in midgut, fat body, hematopoietic organs (HOs), and hemocytes, and determined hemolymph antimicrobial activity. Hemocytes and HOs were tested for presence and distribution of lysozyme mRNA and protein.

Results

The midgut and circulating hemocytes exhibited a significantly increased level of lysozyme mRNA in response to gut infection but did not significantly alter expression in response to a systemic infection. Conversely, fat body and HOs responded to both infection models by altered mRNA levels of at least one gene monitored. Most, but not all hemocytes and HO cells contain lysozyme mRNA and protein.

Discussion

These data suggest that the gut recruits immune-related tissues in response to gut infection whereas systemic infections do not induce a response in the midgut. The experimental approach implies a skewed cross-talk: An intestinal infection triggers immune activity in systemic immune organs, while a systemic infection does not elicit any or only a restricted immune response in the midgut. The HOs, which form and release hemocytes in larval M. sexta, i) synthesize lysozyme, and ii) respond to immune challenges by increased immune gene expression. These findings strongly suggest that they not only provide phagocytes for the cellular immune response but also synthesize humoral immune components.

Antibiotic resistance represents one of the greatest threats to global health. The spread of antibiotic resistance genes among bacteria occurs mostly through horizontal gene transfer via conjugation mediated by plasmids. This process implies a direct contact between a donor and a recipient bacterium which acquires the antibiotic resistance genes encoded by the plasmid and, concomitantly, the capacity to transfer the acquired plasmid to a new recipient. Classical assays for the measurement of plasmid transfer frequency (i.e., conjugation frequency) are often characterized by a high variability and, hence, they require many biological and technical replicates to reduce such variability and the accompanying uncertainty. In addition, classical conjugation assays are commonly tedious and time-consuming because they typically involve counting colonies on a large number of plates for the quantification of donors, recipients, and transconjugants (i.e., the bacteria that have received the genetic material by conjugation). Due to the magnitude of the antibiotic resistance problem, it is critical to develop reliable and rapid methods for the quantification of plasmid transfer frequency that allow the simultaneous analysis of many samples. Here, we present the development of a high-throughput, reliable, quick, easy, and cost-effective method to simultaneously accomplish and measure multiple conjugation events in 96-well plates, in which the quantification of donors, recipients, and transconjugants is estimated from the time required to reach a specific threshold value (OD600 value) in the bacterial growth curves. Our method successfully discriminates different plasmid transfer frequencies, yielding results that are equivalent to those obtained by a classical conjugation assay.
