3月30日下午，国防部新闻发言人吴谦大校在国防部举行例行记者会上提到“我国首艘国产航母正在开展舾装工作，进展非常顺利”。对于是不是4月23日海军建军节下水的问题，吴谦表示“相信不会让大家久等”。

The traditional trial and error techniques used in the field of medicine are now being replaced by safe, marker-assisted, accurate, and molecularguided treatments. One such technique is molecular diagnostics. It involves the measurement and analysis of DNA and RNA at the molecular level to signify changes in biochemical pathways. The purpose of performing these tests is to detect the location of a disease and its activity. The factors that are contributing to its importance include the specificity, wide scope of application, and quick turnaround time. The application of this technology in the development and testing of pharmaceuticals has opened up a huge opportunity for molecular diagnostics in the form of CD. Pharmaceutical companies are focusing on R&D in pharmacogenomics to reduce the turnaround time required from the point of discovery of a drug to its approval.

Flow cytometry is a laser or impedance-based technology used in cell sorting, cell counting, biomarker detection, and protein engineering. Flow cytometry allows for indepth analysis of cell structures using software.

Blood loss or anemia can lead to chronic health problems; therefore, clinicians perform blood transfusion that can help to get relief from chronic health problems. To transfuse, blood clinicians or hospitals take blood units present in their own integrated blood banks or from other centers. Immunohematology, also commonly known as blood banking, helps to screen the donor blood components for blood antigens, Rh factor, plasma, and white blood cell components. It helps to reduce blood transfusionrelated diseases such as HIV and thalassemia. According to the guidelines by World Health Organization (WHO), donated blood is screened before it is transfused to protect the people from such fatalities in most of the countries.

Ion-exchange chromatography is a separation process that utilizes the charge of the medium and desired particle. This process can be used for almost any kind of charged molecules ranging from large proteins to small nucleotides and amino acids. Mobile phage refers to the mobile molecules in the mixture. It is usually a concentration of a buffer, pH, and a salt. The opposite charged solute ions get attracted to the stationary phage by electrostatic force, and the stationary phage resin is used to covalently attach anions or cations onto it.

The need for security technologies, including highly reliable and accessible personal authentication and identification systems, has increased mainly due to the frequent instances of security breaches, identity theft, and fraud in different sectors. Biometrics has emerged as a suitable security and monitoring solution to meet this need, as it is based on the behavioral and physiological characteristics of an individual, which are difficult to replicate.

Affinity chromatography is a separation method that utilizes the specific binding interaction between an immobilized ligand and its binding partner for separation and purification. Boronate affinity chromatography is based on the boronate functional group and used for the selective separation and molecular recognition of cis-diolcontaining compounds in industries like healthcare, pharmaceutical, and biotechnology.

Sludge is a blend of liquid and solid wet mud-like components generated during the treatment of wastewater. It is viscous in nature. It contains water, natural materials, chemicals, and microorganisms including pathogens. The sludge produced by different industries include pollutants (heavy metals, pathogens, and organic pollutants) and compounds of agricultural value (organic waste, phosphorus, potassium, nitrogen, calcium, magnesium, and sulfur). The treatment of sludge depends on the pollution load of the treated water, and the characteristics of the sludge depend on the wastewater treatments undertaken.

Security of data and financial assets have been a key concern for banks as well as for customers. Numeric keypads, keys, and identity badges were widely used to prevent unauthorized access to data and premises. With technological advancements, twofactor authentication was introduced, where individuals could gain access to secure premises after they are authenticated twice, via hardware devices and numeric codes. However, hackers can gain access to hardware devices and obtain numeric codes, which increases the security risks, especially in the BFSI sector.

A biometric sensor is a transducer, which converts the biometric input signal (fingerprints, voice, vein patterns, or facial traits) of its user into an electrical signal. In order to authenticate any biometric measurement, a biometric sensor is required to scan the user's fingerprint or voice or face in the hardware set.
